Dolor lumbar crónico y la conducta sedentaria en estudiantes universitarios de medicina / Chronic Low Back Pain and Sedentary Behavior in Medical College Students / Dor lombar crônica e comportamento sedentário em estudantes universitários de medicina

Introducción: el dolor lumbar (dl) es una condición frecuente en los estudiantes de medicina y a partir de ahí se identifican diversos factores de riesgo. El objetivo del estudio fue evaluar la asociación entre la presencia de dlen los últimos 12 meses y la conducta sedentaria en estudiantes de medicina de una universidad privada. Materiales y métodos: estudio transversal analítico, prospectivo observacional, en el que participaron 167 encuestados. La conducta sedentaria se evaluó junto con la actividad física, a través del Cuestionario Mundial sobre Actividad Física; mientras que el dlse midió con el Cuestionario Nórdico de Kuorinka de Trastornos Musculoesqueléticos. Además, se valoraron variables demográficas y académicas como sexo, edad y ciclo universitario de los participantes. Resultados: se encontró una frecuencia de dldel 67.7 % y una media de conducta sedentaria de 9.5 horas (dt = 3.04). En el análisis mul-tivariado se halló que para cada hora sentado se aumenta significativamente la probabilidad de padecer dl (or = 1.17; p = 0.013). Los estudiantes que permanecen de 10 a más horas sentados/recostados presentan un aumento de riesgo de padecer dl(ora = 4.13; p = 0.001) frente a los que permanecen menos de 10 horas en estas posiciones. Conclusión: por cada hora en posición sedente/recostado, aumenta en 15 % el odds ratio de sufrir dlen los estudiantes, así como que acumular de 10 a más horas al día en posición sedente/recostado aumenta significativamente el padecer dl en los últimos 12 meses.

Introduction: Low back pain is a common condition among medical students, with various risk factors identified. The aim of the study was to evaluate the association between the presence of low back pain in the last 12 months (lbp) and sedentary behavior in medical students at a private university. Materials and Methods: A cross-sectional analytical, prospective observational study was conducted with 167 respon-dents (101 women and 66 men). The main measurements in this study included sedentary behavior and low back pain in the last 12 months. Sedentary behavior was assessed along with physical activity through the Global Physical Activity Questionnaire (gpaq), while low back pain was measured using the Kuorinka Nordic Musculoskeletal Questionnaire. In addition, demographic and academic variables such as gender, age, and academic cycle of the participants were assessed. Results: A frequency of low back pain of 67.7% and an average sedentary behavior of 9.5 hours (sd = 3.04) were found, 70.1% maintain a healthy level of physical activity. Greater sedentary behavior was found to be associated with a greater presence of lbp. In the multivariate analysis, it was found that for each hour seated, the likelihood of suffering lbpsignificantly increased (or = 1.17; p = 0.013). Students who remain seated/reclined for 10 or more hours have an increased risk of suffering low back pain (aor = 4.13; p = 0.001) compared to those who spend less than 10 hours in these positions. Conclusion: It is observed that for each hour in a seated/reclined position, the odds ratio of suffering low back pain in students increases by 15%, and accumulating 10 or more hours a day in a seated/reclined position significantly increases the suffering of low back pain in the last 12 months.

Introdução: a dor lombar é uma condição comum entre os estudantes de medicina, com diversos fatores de risco identificados. O objetivo do estudo foi avaliar a associação entre a presença de dor lombar nos últimos 12 meses (dl) e o comportamento sedentário em estudantes de medicina de uma universidade privada. Materiais e métodos: foi realizado um estudo transversal analítico, observacional prospectivo com 167 respondentes (101 mulheres e 66 homens). As principais medidas neste estudo incluíram o comportamento sedentário e a dor lombar nos últimos 12 meses. O comportamento sedentário foi ava-liado juntamente com a atividade física através do Questionário Mundial sobre Atividade Física (gpaq), enquanto a dor lombar foi medida usando o questionário nórdico de Kuorinka de transtornos muscu-loesqueléticos. Além disso, foram avaliadas variáveis demográficas e acadêmicas como o sexo, a idade e o ciclo acadêmico dos participantes. Resultados: foi encontrada uma frequência de dor lombar de 67,7% e uma média de comportamento sedentário de 9,5 horas (dp = 3,04), 70,1% mantêm um nível saudável de atividade física. Um maior comportamento sedentário foi encontrado associado a uma maior presença de dl. Na análise multivariada, verificou-se que para cada hora sentada, a probabilidade de sofrer dlaumenta significativamente (or = 1,17; p = 0,013). Estudantes que permanecem sentados/reclinados por 10 ou mais horas têm um risco aumentado de sofrer dor lombar (ora = 4,13; p = 0,001) em comparação com aqueles que passam menos de 10 horas nessas posições. Conclusão: observa-se que para cada hora em posição sentada/reclinada, a razão de chances de sofrer dor lombar nos estudantes aumenta em 15%, e acumular 10 ou mais horas por dia em posição sentada/reclinada aumenta significativamente o sofri-mento de dor lombar nos últimos 12 meses.

Association between sedentary behaviors with cardiorespiratory fitness and executive function among adolescents / 中国学校卫生

Objective@#To explore the relationship between sedentary behavior with cardiorespiratory fitness and executive function in adolescents, and to provide some references for sedentary behavior prevention and executive function improvement.@*Methods@#From September to December 2022, a total of 5 018 adolescents aged 13 to 18 years were selected by stratified random sampling method in Shanghai, Suzhou, Taiyuan,Wuyuan, Xingyi, and Urumqi to conduct physical activity survey, as well as cardiorespiratory fitness and executive function assessment. Pearson s correlation was used to analyze the relationship between sedentary behavior, cardiorespiratory fitness and executive function. The mediation effect model was fitted by the bootstrap mediation procedure in the PROCESS (version 3.3 ) SPSS macro compiled by Haves, and the mediation effect of adolescents cardiorespiratory fitness in the relationship between static behavior and executive function was examined using model 4 in the PROCESS SPSS macro, where Boosrap method was used to compute the mediation effect of adolescents cardiorespiratory fitness. where the Boosrap method was used to calculate confidence intervals for the mediating effects.@*Results@#Adolescents daily sedentary time was positively correlated with both the refreshing function (1-back and 2-back) and the switch function reaction time ( r =0.05, 0.07, 0.05, P <0.01). Adolescent VO 2max was negatively correlated with both the refreshing function (1-back,2-back) and the switching function ( r =-0.09, -0.14 , -0.11, P <0.01). Adolescents daily sedentary time was negatively correlated with VO 2max ( r =-0.04, P <0.01); cardiorespiratory fitness mediated effect values between sedentary behavior and refreshing function (1-back and 2-back) and converted function were 0.20(95% CI =0.06-0.36), 0.43(95% CI =0.14-0.74) and 0.13 (95% CI =0.04-0.22), with mediating effect shares of 6.87%, 8.33% and 8.59%, respectively.@*Conclusion@#The duration of sedentary behavior in adolescents is related to executive function performance, and cardiorespiratory fitness may serve as a mediator to mediate the association between sedentary behavior and executive function in adolescents.

Habitual physical activity and sedentary behavior as predictors of dynapenia in older adults: a cross-sectional study

ABSTRACT BACKGROUND: Dynapenia is a risk factor of mortality. Therefore, the development of low-cost and easy-to-apply tools is essential to optimize the health surveillance actions of older people. OBJECTIVES: To compare the time spent on habitual physical activity (HPA) and sedentary behavior (SB) among dynapenic and non-dynapenic older adults and ascertain the predictive ability of these behaviors on outcome. DESIGN AND SETTING: A cross-sectional population epidemiological survey was conducted involving 208 older adults. METHODS: HPA and SB were quantified using the International Physical Activity Questionnaire, and dynapenia was identified by handgrip strength (women: 18.37 kgf; men: 26.75 kgf). RESULTS: The prevalence was 24.50%. In both sexes, dynapenic individuals reported a HPA median time of 70.00 minutes/week (min/wk), while non-dynapenic women and men reported HPA median times of 240.00 and 280.00 min/wk, respectively (P < 0.05). For SB among dynapenic individuals, a median of 388.75 min/day was observed in women and 428.57 min/d in men. In contrast, non-dynapenic women and men had 291.42 and 274.28 min/day in SB (P < 0.05), respectively. The best cutoff HPA to discriminate the outcome was 150.00 min/wk in women (sensitivity: 73.30%; specificity: 60.67%) and 140.00 min/wk in men (sensitivity, 71.43%; specificity, 61.54%). The best cutoff SB was 381.43 min/day in women (sensitivity, 53.30%; specificity, 84.80%) and 351.43 min/day in men (sensitivity, 71.43%; specificity, 73.85%). CONCLUSION: Older individuals with dynapenia spent less time on HPA and more time in SB. Furthermore, HPA was found to be a better discriminator of dynapenic individuals, and SB better discriminated non-dynapenic individuals.

Influence of the COVID-19 pandemic on sleep quality, psychosocial aspects, and physical activity levels in patients with chronic pain in Brazil: COVIDor cross-sectional study / Influência da pandemia de COVID-19 na qualidade do sono, em aspectos psicoemocionais e no nível de atividade física de pacientes com dor crônica no Brasil: estudo observacional COVIDor

ABSTRACT BACKGROUND AND OBJECTIVES: The social distancing of COVID-19 pandemic exacerbated symptoms of chronic pain patients. Furthermore, it is necessary to consider the sociocultural context of coping with the pandemic in different countries. The objective of this study was to evaluate pain, psychoemotional symptoms, sleep quality, and level of physical activity in chronic pain patients during the COVID-19 pandemic in Brazil. METHODS: Individuals with fibromyalgia, migraine and chronic low back pain were included. The survey was performed through a questionnaire elaborated by researchers on the Forms application, from Google Drive, in the period between October 2020 and March 2021, with straight and clear questions about pain, psychoemotional aspects, sleep quality, and level of physical activity. Binary or multinominal logistic regression analysis was performed to identify possible predictors. RESULTS: 973 people were evaluated, 63.5% had fibromyalgia, and 98.3% were female. Anxiety increased the odds ratio in 395% of chronic pain patients to feel pain (ß: 1.375; OR: 3.956; p=0.001) and a greater intensity of pain increases in 62.3% the chance of these individuals not performing physical activity (ß: -0.474; OR: 0.623; p=0.001). Pain intensity increased the odds ratio of having insomnia by 186.9% (ß: 0.625; OR: 1.869; p=0.001) and the chance of taking sleep drugs by 160.4% (ß: 0.472; OR: 1.604; p=0.001). CONCLUSION: The social isolation of COVID-19 pandemic maximized the vicious cycle between painful symptoms, anxiety, and sleep disorders in chronic pain patients in Brazil. The intensification of these factors is associated with the reduction of physical activity levels.

RESUMO JUSTIFICATIVA E OBJETIVOS: A pandemia de COVID-19 exacerbou os sintomas de pacientes com dor crônica. Porém, é necessário considerar o contexto sociocultural de enfrentamento da pandemia nos diferentes países. O objetivo deste estudo foi avaliar a dor, os sintomas psicoemocionais, a qualidade do sono e o nível de atividade física em pacientes com dor crônica durante a pandemia de COVID-19 no Brasil. MÉTODOS: Foram incluídos indivíduos com fibromialgia, enxaqueca e dor lombar. O levantamento foi realizado por meio de questionário elaborado pelos pesquisadores no aplicativo Forms, do Google Drive, entre outubro de 2020 e março de 2021, com perguntas diretas e claras sobre dor, aspectos psicoemocionais, qualidade do sono e nível de atividade física. Análise de regressão logística binária ou multinominal foi realizada para identificar possíveis preditores. RESULTADOS: Foram avaliadas 973 pessoas, 63,5% apresentavam fibromialgia, sendo 98,3% do sexo feminino. A ansiedade aumentou a razão de chances em 395% dos pacientes com dor crônica sentirem dor (ß: 1,375; OR: 3,956; p= 0,001) e a dor aumentou em 62,3% a chance desses indivíduos não realizarem atividade física (ß: -0,474; OR: 0,623; p=0,001). A intensidade da dor aumentou a razão de chances de ter insônia em 186,9% (ß: 0,625; OR: 1,869; p= 0,001) e a chance de tomar fármacos para dormir em 160,4% (ß: 0,472; OR: 1,604; p=0,001). CONCLUSÃO: O isolamento social da pandemia de COVID-19 maximizou o ciclo vicioso entre sintomas dolorosos, ansiedade e distúrbios do sono em pacientes com dor crônica no Brasil. A intensificação desses fatores está associada à redução de atividade física.

Sedentary behavior, abdominal obesity and healthcare costs in Brazilian adults with cardiovascular diseases: a cross-sectional study

ABSTRACT BACKGROUND: Research on the economic burden of sedentary behavior and abdominal obesity on health expenses associated with cardiovascular diseases is scarce. OBJECTIVE: The objective of this study was to verify whether sedentary behavior, isolated and combined with abdominal obesity, influences the medication expenditure among adults with cardiovascular diseases. DESIGN AND SETTING: This cross-sectional study was conducted in the city of President Prudente, State of São Paulo, Brazil in 2018. METHODS: The study included adults with cardiovascular diseases, aged 30-65 years, who were treated by the Brazilian National Health Services. Sedentary behavior was assessed using a questionnaire. Abdominal obesity was defined by waist circumference. Medication expenditures were verified using the medical records of each patient. RESULTS: The study included a total of 307 adults. Individuals classified in the group with risk factor obesity combined (median [IQ] USD$ 29.39 [45.77]) or isolated (median [IQ] USD$ 27.17 [59.76]) to sedentary behavior had higher medication expenditures than those belonging to the non-obese with low sedentary behavior group (median [IQ] USD$ 13.51 [31.42]) (P = 0.01). The group with combined obesity and sedentary behavior was 2.4 (95%CI = 1.00; 5.79) times more likely to be hypertensive. CONCLUSION: Abdominal obesity was a determining factor for medication expenses, regardless of sedentary behavior, among adults with cardiovascular diseases.

Isotemporal substitution analysis of time between sleep, sedentary behavior, and physical activity on depressive symptoms in older adults: a cross-sectional study

ABSTRACT BACKGROUND: Compared to young individuals, older adults participate more in sedentary behavior (SB) and less in physical activity (PA). These behaviors are associated with numerous adverse health factors. OBJECTIVE: The purpose of the study was to examine the hypothetical effects of substituting time spent sleeping, performing SB, and performing moderate-to-vigorous physical activity (MVPA) on depressive symptomatology in older adults. DESIGN AND SETTING: An analytical cross-sectional study employing exploratory survey methods was conducted in the city of Alcobaça in the state of Bahia, Brazil METHODS: The study included 473 older adults who answered a structured questionnaire during an interview. Exposure time to SB and PA level were assessed using the International Physical Activity Questionnaire, and depressive symptoms were analyzed using the short version of the Geriatric Depression Scale. An isotemporal replacement model was used to evaluate the effects of different SB sessions on depressive symptomatology. RESULTS: An increase in the risk of depressive symptoms was observed when MVPA and sleep time were substituted for the same SB time at all times tested, with maximum values of 40% and 20%, respectively. Opposite substitution of MVPA and sleep time increments reduced the risk of depressive symptomatology by 28% and 17%, respectively. CONCLUSIONS: The results of the present study indicate that replacing SB with the same amount of sleep or MVPA may reduce depressive symptoms. The longer the reallocation time, the greater are the benefits.

Baixos Níveis de Atividade Física e suas Associações com o Estado de Humor, Sonolência Diurna e Consumo Alimentar em Universitários / Low Levels of Physical Activity and its Associations with Mood State, Daytime Sleepiness and Food Consumption in University Students

O ingresso em um curso universitário leva a mudanças significativas no estilo de vida e na rotina do estudante, com impacto na prática de atividade física, saúde mental, hábitos de sono e hábitos alimentares. O objetivo do estudo foi verificar o nível de atividade física dos jovens universitários e suas associações com estado de humor, qualidade do sono e consumo alimentar. Trata-se de uma pesquisa de corte transversal, realizada com estudantes universitários do curso de Medicina de uma Instituição de Ensino Superior Pública. Realizou-se avaliação de medidas antropométricas, do nível de atividade física (NAF) por meio do acelerômetro GT3x (Actigraph), do consumo alimentar (inventário de 24h), e utilizando os questionários de BECK e BRUMs / POMS avaliou-se os distúrbios de sono e estado de humor. Utilizando o software SPSS realizou análise comparativa com teste t Student para grupos independentes, análise inferencial de correlação de Pearson e Regressão logística binária. Dos universitários analisados (n=75), 54,7% (n=41) eram do sexo masculino e, quando comparado com as mulheres, apresentaram maior nível de atividade física (NAF). Aproximadamente 1/3 de toda a amostra do estudo realizou menos de 300min de atividade física moderada/vigorosa. O perfil alimentar dos universitários não foi satisfatório. Verificou-se para ambos os sexos o Escore Total de POMS (Profile of Mood States) se associou com universitários que realizam menos de 300min de atividade física por semana. As mulheres têm 65% mais chances de apresentar Escala de Tensão (POMS) quando são menos ativas, e nos homens, a razão de chances é de aproximadamente três vezes maior de apresentar Confusão (BRUMS - Escala de Humor de Brunel). Conclui-se que os estudantes universitários do curso estudado, em sua maioria, foram insuficientemente ativos fisicamente e apresentam algumas alterações no estado de humor, sonolência diurna e um consumo alimentar insatisfatório.

Starting a university course leads to significant changes in the student's lifestyle and routine, with an impact on physical activity, mental health, sleeping habits and eating habits. The objective of the study was to verify the level of physical activity of young university students and its associations with mood, sleep quality and food consumption. This is a cross-sectional survey, carried out with university students studying Medicine at a Public Higher Education Institution. Anthropometric measurements, physical activity level (PAL) were assessed using the GT3x accelerometer (Actigraph), food consumption (24-hour inventory), and using the BECK and BRUMs / POMS questionnaires, health disorders were assessed. sleep and mood. Using SPSS software, comparative analysis was carried out with Student's t test for independent groups, Pearson correlation inferential analysis and binary logistic regression. Of the university students analyzed (n=75), 54.7% (n=41) were male and, when compared to women, they had a higher physical activity level (PAL). Approximately 1/3 of the entire study sample performed less than 300 minutes of moderate/vigorous physical activity. The dietary profile of university students was not satisfactory. For both sexes, the POMS Total Score (Profile of Mood States) was found to be associated with university students who perform less than 300 minutes of physical activity per week. Women are 65% more likely to present with Tension Scale (POMS) when they are less active, and in men, the odds ratio is approximately three times greater for presenting Confusion (BRUMS - Brunel Mood Scale). It is concluded that the majority of university students on the course studied were insufficiently physically active and presented some changes in mood, daytime drowsiness and unsatisfactory food consumption.

Sedentary behavior among medical students: repercussions of the coronavirus pandemic / Conduta sedentária entre estudantes de medicina: repercussões da pandemia do coronavírus

ABSTRACT Introduction: In order to face COVID-19, social restriction measures were adopted that influenced the population's living habits, increasing sedentary lifestyle. Considering the high complexity and dedication required by the Medicine course, it becomes relevant to investigate the effect of the pandemic on the practice of physical exercise and sedentary behavior of these students. Objective: Identify changes in physical activity and sedentary behavior self-reported by medical students in the city of Salvador, Bahia, before and during the self-confinement imposed by the COVID-19 pandemic. Methods: Longitudinal, prospective, quantitative study carried out with regularly enrolled medical students over 18 years of age. A virtual, structured, anonymous, self-completed questionnaire was applied, containing sociodemographic and academic aspects. In addition, the International Physical Activity Questionnaire (IPAQ) was applied in its short version, considering the period before and during the pandemic. Through this, the level of physical activity, sedentary behavior and time spent walking and performing moderate and vigorous activities were measured. Results: 268 medical students were included, predominantly women (65.7%), white (50.0%) and mixed race (38.8%), aged 24.2 ± 5.5 years, single (90.7%), attending the clinical cycle (59.0%), in private institutions (78.4%). No statistically significant differences were identified in the level of physical activity and in the time spent with moderate and vigorous activities. However, there was a reduction in walking time (p<0.00001) and an increase in sedentary behavior (p=0.001) during the COVID-19 pandemic, with the greatest impact among women (p=0.0009). Conclusion: The repercussions of the COVID-19 pandemic have been shown to increase the sedentary behavior of medical students, especially among women, and to reduce activity time spent with walking. Longitudinal studies are needed to analyze the medium and long-term consequences of this change in the healthy lifestyle habits of medical students. Level of evidence II; Comparative prospective study.

Impact of the COVID-19 pandemic isolation concerning physical activity and cardiovascular health / Impacto do isolamento da pandemia de COVID-19 na atividade física e na saúde cardiovascular

Background: Regular physical activity (PA) is essential for health maintenance and disease prevention. COV-ID-19 and its social isolation affected patients with cardiovascular (CV) disease. This is a scoping review aiming to map, analyze, and summarize the impacts caused by the isolation of the COVID-19 pandemic concerning PA and CV health in adults. Methods: The review was based on PRISMA-ScR. PubMed, PubMed Central, BVS/BIREME, Scopus, Web of Science, CINAHL, Brazilian Digital Library of Theses and Dissertations, and SciELO databases were selected to search. Two search phases were performed: May 2021 and March 2022. English-language full-text papers were included. Initially, the titles and abstracts of the retrieved documents were read and screened based on the research question. A third reviewer resolved disagreement through consensus meetings. An assessment form was adapted for data extraction. The study was registered in the Open Science Framework platform under the DOI https://doi.org/10.17605/OSF.IO/AH6P8. Results: 11 papers were included and demonstrated that regular PA could be challenging in social isolation environments. Most participants were moderately active and performed low-intensity PA. Confinement led to the limitation of everyday activities, nutritional disorders, and reduced PA, contributing to weight gain. Quarantine was associated with stress and depression, leading to an unhealthy diet (AU).

Introdução: A prática regular de atividade física (AF) é essencial para a manutenção da saúde e prevenção de doenças. A COVID-19 e seu isolamento social afetaram pacientes com doenças cardiovasculares (CV) na prática dessas atividades. Desta forma, realizou-se uma revisão de escopo com o objetivo de mapear, analisar e sintetizar os impactos causados pelo isolamento da pandemia de COVID-19 na realização de AF e na saúde CV em adultos. Métodos: A revisão foi baseada no PRISMA-ScR. Foram selecionadas para a pesquisa a PubMed, PubMed Central, BVS/BIREME, Scopus, Web of Science, CINAHL, Biblioteca Digital Brasileira de Teses e Dissertações e bases de dados SciELO. Duas fases de busca foram realizadas: maio de 2021 e março de 2022. Foram incluídos artigos que possuíam texto completo em inglês. Inicialmente, os títulos e resumos dos documentos recuperados foram lidos e triados com base na questão de pesquisa. Um terceiro revisor foi utilizado para avaliar os desacordos por meio de reuniões de consenso. Um formulário de avaliação foi adaptado para extração de dados. O estudo foi registrado na plataforma Open Science Framework sob o DOI https://doi.org/10.17605/OSF.IO/AH6P8. Resultados: 11 artigos foram incluídos neste estudo e demonstraram que a AF regular pode ser desafiadora em ambientes de isolamento social. A maioria dos participantes era moderadamente ativa e praticava AF de baixa intensidade. O confinamento levou à limitação das atividades cotidianas, distúrbios nutricionais e diminuição da AF, contribuindo para o ganho de peso. A quarentena foi associada ao estresse e à depressão, levando a uma dieta pouco saudável. Possíveis soluções apontam para a realização de AF domiciliar, considerando a saúde basal e o estado CV. Conclusão: A era pós-COVID-19 e suas consequências apontam para a necessidade de planejamento de estratégias que aumentem e mantenham a AF domiciliar como medida protetora para a população em geral, considerando saúde CV, recursos e espaço domiciliar (AU).

Habilidades Cognitivas y Quiebres en la Conducta Sedentaria en Niños Chilenos / Cognitive Skills after Breaks in Sedentary Behavior in Chilean Children

Introducción. En Chile las tasas de sedentarismo infantil han aumentado, siete de cada 10 niños no cumple con los estándares mínimos recomendados por la Organizaciónn Mundial de la Salud. Faltan en Chile estudios que asocien el sedentarismo de tiempo libre y las horas sedentes en jornada escolar con las habilidades cognitivas. Objetivo. Determinar los cambios en las habilidades cognitivas posterior a la realización de quiebres en la conducta sedentaria. Métodos. Participaron 83 alumnos de 12 a 14 años, pertenecientes a 7° y 8° básico de la región metropolitana de Santiago de Chile. Los alumnos fueron distribuidos aleatoriamente como casos (42) y control (41). Se realizó durante 10 días, un protocolo de quiebres en la conducta sedentaria de 3 minutos cada 40 minutos, durante toda la jornada escolar. Ambos grupos tuvieron evaluaciones fisiológicas y aplicación de test de memoria y atención pre y post intervención. Resultados. Se encontraron diferencias estadísticamente significativas en la variable de atención con un valor p-value de (< 0,005) a favor del grupo intervenido. En valores de presión arterial sistólica y frecuencia cardiaca se evidencio un descenso significativo en el grupo intervenido (p<0,005) Conclusión. En este estudio se demuestra que el protocolo aplicado, mejora la habilidad cognitiva de atención en la población estudiada y además se reducen los valores de parámetros fisiológicos.

Background. In Chile, child sedentary lifestyle rates have increased; seven out of 10 children do not meet the minimum standards recommended by the World Health Organization. There is a lack of studies in Chile that associate free-time sedentary behavior and seated hours during the school day with cognitive skills. Objective. To determine the changes in cognitive abilities after the completion of sedentary behavior breaks. Methods. 83 students from 12 to 14 years old participated, belonging to 7th and 8th grade of the metropolitan region of Santiago de Chile. Students were randomly distributed as cases (42) and control (41). A protocol of sedentary behavior breaks of 3 minutes every 40 minutes was carried out during 1 week, during the whole school day. Both groups had physiological evaluations and application of memory tests and pre and post intervention care. Results. Statistically found differences were found both in the care variables with a p-value of <0.005 in favor of the intervened group, as well as in the systolic blood pressure and heart rate values evidencing a significant decrease in the intervened group (p < 0.005) Conclusion. This study shows that the applied protocol improves the cognitive ability of attention in the studied population and also reduces values of physiological parameters.

Dietary patterns associated with physical activity and sedentary behavior in university students in Mexico

Dietary patterns (DPs) are conditioned by a large number of factors, including physical activity and sedentary lifestyle, however, there is limited information on their interaction. This study aimed to identify DPs and their associations with physical activity and sedentary behavior among university students from Mexico. We conducted a cross-sectional, observational and analytical study. The participants were university students from Southwest Mexico. A total of 419 participants who did not suffer from any disease that affects oral nutrition or that prevented them from performing physical activity were included. DPs were generated from a principal component analysis and associations were analyzed using a logistic regression model. Three DPs were identified: "western", "prudent" and "traditional". The traditional pattern was significantly associated with high physical activity (OR: 2.78; 95% CI: 1.34-5.75) and was a protective factor against sedentary lifestyle (OR: 0.35; 95% CI: 0.13-0.93). The results show that a high physical activity and a lower sedentary lifestyle were associated with a healthier dietary pattern in the study population. It is important to implement interventions towards nutrition, physical activity and sedentary behavior for the population being studied.

Los patrones dietéticos están condicionados por una gran cantidad de factores, entre ellos la actividad física y el sedentarismo, sin embargo, existe poca información sobre su interacción. Este estudio tuvo como objetivo identificar patrones dietéticos y sus asociaciones con la actividad física y el comportamiento sedentario entre estudiantes universitarios del suroeste de México. Se trata de un estudio transversal, observacional y analítico. Los participantes fueron estudiantes universitarios del suroeste de México. Se incluyeron un total de 419 participantes que no padecían alguna enfermedad que condicionara su nutrición oral, ni condición que les impidiera realizar actividad física. Se realizó un análisis de componentes principales para determinar los patrones dietéticos, mientras que se utilizó un modelo de regresión logística para verificar las asociaciones. Se identificaron tres patrones dietéticos: "occidental", "prudente" y "tradicional". El patrón tradicional se asoció significativamente con actividad física elevada (OR: 2,78; IC 95%: 1,34-5,75) y fue un factor protector contra el sedentarismo (OR: 0,35; IC 95%: 0,13-0,93). Los resultados muestran que una alta actividad física y un menor sedentarismo se asociaron con un patrón dietético más saludable en la población de estudio. Es importante implementar intervenciones hacia la nutrición, la actividad física y el sedentarismo para la población en estudio.

Relación entre actividad física, sedentarismo y obesidad en adultos, Colombia, 2015

Introducción. La inactividad física y los comportamientos sedentarios demostraron ser factores de riesgo en la prevalencia de enfermedades como la obesidad. Objetivo. Analizar la relación entre la actividad física, el sedentarismo y el estado nutricional en la población de 18 a 64 años en Colombia, 2015. Materiales y métodos. Se llevó a cabo el análisis secundario de la encuesta de nutrición de Colombia en 2015, utilizando variables sociodemográficas (edad, sexo, etnia, área geográfica, región e índice de riqueza) y, además, peso, talla, actividad física y sedentarismo. Se estimaron proporciones e intervalos de confianza al 95 %, utilizando la prueba de ji al cuadrado, regresión logística y razón de momios (Odds ratio). Resultados. La población analizada incluyó 16.607 individuos (54,8 % mujeres y 45,2 % hombres) de 18 a 64 años. Los hombres tuvieron más sobrepeso (37,6 %) que las mujeres, mientras que la obesidad fue más frecuente en mujeres (22,1 %). El 48,3 % no cumple con la recomendación de actividad física; 56,9 % de los adultos pasa dos o más horas al día mirando pantallas. Hubo una asociación significativa (p<0,050) entre el incumplimiento de las recomendaciones de actividad física y la obesidad. Además, el cumplir con la recomendación de actividad física disminuye 1,25 veces la probabilidad de obesidad. Conclusión. La obesidad es un problema de salud para la población adulta, con mayor prevalencia en las mujeres y en los mayores de 30 años. Se relaciona con el incumplimiento de las recomendaciones sobre actividad física y con los comportamientos sedentarios (los cuales son más prevalentes en los afrodescendientes), el cuartil alto de riqueza, el vivir en área urbana y el vivir en Bogotá.

Introduction. Physical inactivity and sedentary behaviors were shown to be risk factors in the prevalence of diseases such as obesity. Objective. To conduct an analysis of the relationship between physical activity, sedentary lifestyle and nutritional status in the population aged 18 to 64 years in Colombia, 2015. Materials and methods. A secondary analysis of the 2015 Colombian nutrition survey was done, using sociodemographic variables (age, sex, ethnicity, geographic area, region, wealth index), along with weight, height, physical activity and sedentary lifestyle. Proportions and 95% confidence intervals, chi-square, logistic regression and odds ratio were estimated. Results. The analyzed population included 16,607 individuals (54.8% women and 45.2% men) aged 18 to 64 years. Men were more overweight (37.6%) than women, while obesity was more frequent in women (22.1%). It was observed that 48.3% did not meet the physical activity recommendations; 56.9% of adults spent two or more hours a day watching screens. There was a significant association (p<0.050) between non-compliance with physical activity recommendations and obesity. In addition, complying with the physical activity recommendation decreases the probability of obesity by 1.25 times. Conclusion. Obesity is a health problem for the adult population, with a higher prevalence in women and in those over 30 years old. It is related to non-compliance with the recommendations about physical activity and sedentary behaviors (which are more prevalent in Afro-descendants), high wealth quartile status, and to reside in urban areas and to live in the Bogotá area.

Factores asociados a baja agudeza visual en una población escolar de la ciudad de Bucaramanga, Colombia / Factors Associated with Low Visual Acuity in a School Population in the City of Bucaramanga, Colombia / Fatores associados à baixa acuidade visual em uma população escolar da cidade de Bucaramanga, Colômbia

Introducción. La baja agudeza es un problema de salud pública en el mundo, que aumenta año tras año, relacionada con factores comportamentales poco saludables como el sedentarismo. La baja agudeza afecta especialmente a escolares, en quienes la visión representa uno de los sistemas más importantes para su desarrollo, tanto para el aprendizaje como para las relaciones sociales. El objetivo es establecer asociación entre baja agudeza visual y características sociodemográficas y comportamentales en una población escolar de la ciudad de Bucaramanga, Colombia. Metodología. Estudio observacional de corte transversal basado en datos recolectados de encuestas a estudiantes de una institución educativa de Bucaramanga entre los años 2006 y 2017, sobre las cuales se realizó un análisis bivariado entre características sociodemográficas y comportamentales con baja agudeza visual. Resultados. La prevalencia de baja agudeza visual fue de 33.57%, con mayor prevalencia de baja agudeza visual en mujeres y aquellos con mayor índice de masa corporal. La agudeza visual baja no tuvo asociación estadísticamente significativa con las otras variables estudiadas. Discusión. Las mujeres tienen una mayor prevalencia de baja agudeza visual. Parece existir una relación entre la actividad física y la agudeza visual. Conclusiones. Las diferencias encontradas según el sexo pueden deberse a patrones comportamentales diferentes entre hombres y mujeres, como la actividad física y el sedentarismo. Hacen falta estudios que evalúen la causalidad de la asociación entre los problemas de agudeza visual y los hábitos de vida poco saludables.

Introduction. Low visual acuity is a public health problem worldwide, which is increasing year by year, and it is associated with unhealthy behavioral factors such as sedentary lifestyle. Low visual acuity particularly affects schoolchildren, whom eyesight is one of the most important abilities for their development, both in terms of learning and social interactions. The objective of this study is to establish an association between low visual acuity, sociodemographic, and behavioral characteristics of a student population in Bucaramanga, Colombia. Methodology. This was a cross-sectional observational study based on data collected from surveys of students within an educational institution sited in Bucaramanga between 2006 and 2017. A bivariate analysis was conducted between sociodemographic and behavioral characteristics and low visual acuity. Results. The prevalence of low visual acuity was 33.57%, with a higher prevalence of low visual acuity in women and those with a higher body mass index. However, low visual acuity didn't have a statistically significant association with the other variables studied. Discussion. Women have a higher prevalence of low visual acuity. There appears to be an association between physical activity and visual acuity. Conclusions. The encountered differences according to sex may be due to different behavioral patterns between males and females, such as physical activity and sedentary lifestyle. Further studies are needed to assess the causality of the association. Keywords: Visual Acuity; Adolescent; Sedentary Behavior; Vision, Ocular; Vision, Low.

Obesogenic behavior clusters associated with weight status among Brazilian students: a latent class analysis / Agrupamentos de comportamentos obesogênicos associados com status de peso em estudantes brasileiros: uma análise de classe latente

Abstract This study aimed to examine the association between clusters of physical activity (PA), diet, and television viewing (TV) with weight status among a representative sample of Brazilian students. Data from the National Health School-based Survey (PeNSE) 2015 were analyzed (n = 16,521; mean age 14.8, standard deviation 0.03 year). PA (minutes/week spent in leisure-time, and commuting to/from school), TV (hours/day), and weekly consumption of deep-fried empanadas, candies, sodas, ultra-processed foods, fast foods, green salads or vegetables, and fruits were self-reported on the validated PeNSE questionnaire. Latent class analysis defined behavior classes, and binary logistic regression assessed the association between clustering and weight status. Six classes' types with positive and negative behaviors were identified. Adolescents belonging to the "low TV time and high healthy diet" class had higher chances of being overweight (including obesity) compared to their peers in the "moderate PA and mixed diet" class. No associations were found in the other clusters. Mixed classes with healthy and unhealthy behaviors characterized adolescents' lifestyles and these profiles were related to weight status.

Resumo O estudo objetivou examinar a associação entre agrupamentos de atividade física (AF), dieta e tempo de televisão (TV) com o status do peso em uma amostra representativa de estudantes brasileiros. Foram analisados ​​dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2015 (n = 16.521; idade média 14,8, desvio padrão de 0,03 ano). AF (minutos/semana no lazer e deslocamento para/da escola), assistir televisão (TV) (horas/dia), consumo semanal de doces, refrigerantes, alimentos ultraprocessados/fast-foods, saladas/vegetais e frutas foram coletadas por questionário validado. Análise de classes latentes definiu os perfis de comportamento e a regressão logística binária a associação entre agrupamento e status de peso. Foram identificadas seis classes com comportamentos positivos e negativos. Adolescentes pertencentes à classe "baixo tempo de TV e alta alimentação saudável" apresentaram maior probabilidade de ter sobrepeso/obesidade em comparação com seus pares na classe "AF moderada e dieta mista". Não foram encontradas associações nos outros perfis. Classes com comportamentos saudáveis ​​e não saudáveis ​​caracterizaram o estilo de vida dos adolescentes e estiveram relacionadas com o status de peso.

Obesity in Adolescents: Prevalence and Association with Sociodemographic and Lifestyle Factors

Introduction: Overweight and obesity has become a worldwide epidemic and is a growing public health concern. The increase in prevalence and severity of obesity among children and adolescents has been attributed largely to behavioral factors such as changing eating habits and sedentary lifestyles. Objective: To determine prevalence of obesity and abdominal obesity among adolescents and its association with sociodemographic factors and lifestyle. Methods: Present cross-sectional study was conducted in the urban field practice area under the Community Medicine Department of LLRM Medical College, Meerut, among 872 adolescents. All localities in the field area were covered and house to house survey was done. Questions were asked about eating patterns, physical activity and sedentary lifestyle. Data was collected and analyzed using appropriate statistical tests. Results: The prevalence of overweight and obesity was 17.43, 6.88%, respectively. Obesity was significantly higher among females, those who indulged in unhealthy eating habits were physically inactive, watched television for a longer duration and ate junk while watching television. Conclusion: In the present study, we found that high junk food consumption and a sedentary lifestyle were found to be significantly associated with childhood overweight/obesity. As a result, timely interventions should be taken to improve awareness about healthy lifestyle behavior to prevent obesity and its complications among adolescents.

Main results and public health implications of the National School Health Survey (ENSE), Colombia 2017

Introduction: The school population represents a fundamental group for health promotion actions, given that the foundations of healthy behaviors in adult life are established in children and adolescents, who can be greatly influenced by the school. Objective: To describe the health-related behavioral factors of schoolchildren between 13 and 17 years of age in secondary and middle school in Colombia. Methods: A national cross-sectional study was conducted (i.e., School Health Survey -ENSE-) that recorded information on dietary practices, physical activity, alcohol and drug consumption, injuries and bullying, and oral, visual and hearing health. Sampling was probabilistic, cluster and multistage. Results: Schoolchildren have low consumption of fruits, vegetables (13.1%) and dairy (76.5 %), high consumption of ultra-processed foods (82.4 %), sugary drinks (74.0 %) and fast foods (14.8 %), frequent addition of salt at the table (43.3 %), low compliance with physical activity recommendations (15.0 %) and high sedentary lifestyle (46.3 %), frequent consumption of alcohol (44.7 %) and psychoactive substances (14.7 %), in addition to prevalent situations of bullying (15.4 %), rejection (8.2 %) and verbal aggression (42.7 %). Conclusions: The ENSE shows critical inequalities by gender, ethnicity and social class, throughout the country. The indicators observed in schoolchildren are precursors of various chronic and degenerative diseases and mental illness, which requires the urgent attention of the different social actors in the country.

Introducción: La población escolar es un grupo fundamental para las intervenciones de promoción de la salud, ya que en los niños y adolescentes se sientan las bases de un comportamiento saludable en la vida adulta, que puede ser muy influenciado por la escuela. Objetivo: Describir los factores comportamentales relacionados con la salud de los escolares de 13 a 17 años de edad que cursan educación básica secundaria y media en Colombia. Métodos: Se realizó una encuesta nacional transversal (Encuesta de Salud en Escolares -ENSE-) con los lineamientos de Global School-based Student Health Survey para recolectar información sobre prácticas alimentarias, actividad física, consumo de alcohol y drogas, lesiones e intimidación, y salud bucal, visual y auditiva. El muestreo fue probabilístico, por conglomerados y polietápico. Resultados: Se incluyeron 79.640 escolares de 298 municipios. Los escolares presentaron bajo consumo de frutas, verduras (13.1%) y productos lácteos (76.5 %), alto consumo de alimentos ultraprocesados (82.4 %), bebidas azucaradas (74.0 %) y comidas rápidas (14.8 %); alto uso de sal añadida en la mesa (43.3 %), actividad física inferior a la recomendada (15.0 %) y sedentarismo (46.3 %). Fue frecuente el consumo de alcohol (44.7 %) y sustancias psicoactivas (14.7 %) y reportaron situaciones de intimidación (15.4 %), rechazo (8.2 %) y agresiones verbales (42.7 %). Conclusiones: La ENSE muestra desigualdades por género, etnia y clase social en todo el país. Los hallazgos observados en los escolares son factores de riesgo de enfermedades crónico-degenerativas y mentales, y requieren la atención urgente de los actores sociales del país.

Association between ultraprocessed food consumption and obesity in US adults: an analysis of NHANES 2009-2018 / Asociación entre consumo de alimentos ultraprocesados y obesidad en US adultos: un análisis de NHANES 2009-2018

We propose the following hypothesis: ultraprocessed foods in the global food supply contribute to the worldwide increase in obesity. Objective. To analyze the association between a higher consumption of ultraprocessed foods and the obesity in adulthood in the United States. Materials and methods. United States National Survey of Health and Nutrition Examination (NHANES) (2009-2018) data were used. We included subjects of both sexes, aged between 18-64 years old, with anthropometric, health, income, race/ethnicity and physical activity (PA) data. The association between the ultraprocessed food intake and obesity was calculated using a binomial logistic regression. In addition, we also evaluated a subsample with subjects who did not consume more than their adequate daily energy requirements. Results. We evaluated 13,310 subjects in total, and 4,788 in our subsample. Of these 33% were committed to obesity, and in the subsample the prevalence was even higher, around 49%. In our analysis, we found five factors (ultraprocessed food consumption, sex, age, race/ethnicity, and sedentary lifestyle) that were positively associated with the development of obesity. Compared to subjects who consumed less than 20% of ultraprocessed foods, subjects who consumed between 20 to 40% of ultraprocessed food had 16% more odds of developing obesity [95%CI:1.06­1.26]. For the subsample, the odds were even higher, being around 27% [95%CI:1.11­1.46]. Conclusions. Our results showed a positive association between obesity and the amount of ultraprocessed food consumption, even though, in those who consumed no more than their adequate daily energy requirements(AU)

La hipótesis planteada es que los alimentos ultraprocesados contribuyen al aumento de la obesidad a nivel global. Objetivo. Analizar la asociación entre un mayor consumo de alimentos ultraprocesados y la obesidad en adultos en Estados Unidos. Materiales y métodos:. Se utilizaron datos de la Encuesta Nacional de Examen de Salud y Nutrición de los Estados Unidos (NHANES) (2009-2018). Se incluyeron individuos de 18 a 64 años de ambos sexos, con datos antropométricos, de salud, ingresos, raza/ etnia y actividad física. La asociación entre la ingesta de alimentos ultraprocesados y la obesidad se calculó utilizando un modelo de regresión logística binomial. Además, evaluamos una submuestra con sujetos que no consumieron más que sus requerimientos energéticos diarios adecuados. Resultados. Evaluamos 13.310 sujetos en total y 4.788 en nuestra submuestra. De estos, el 33% comprometidos con la obesidad, y en la submuestra la prevalencia era aún mayor, alrededor del 49%. En nuestro análisis encontramos cinco factores (consumo de alimentos ultraprocesados, sexo, edad, raza/etnia y sedentarismo) asociados positivamente con el desarrollo de obesidad. En comparación con los sujetos que consumían menos del 20% de los alimentos ultraprocesados, aquellos que consumían entre el 20 y el 40 % de los alimentos ultraprocesados tenían un 16% más de probabilidades de desarrollar obesidad [95%IC: 1,06-1,26]. Para la submuestra, las probabilidades fueron aún mayor, rondando el 27% [95%IC: 1,11-1,46]. Conclusiones. Nuestros resultados mostraron una asociación positiva entre la obesidad y la cantidad de consumo de alimentos ultraprocesados, incluso en aquellos que no superaron sus requerimientos energéticos diarios adecuados(AU)

Objetivo: comparar se o indicativo de sarcopenia e comportamento sedentário aumentou durante o isolamento social devido à pandemia de COVID-19 em idosos brasileiros. Métodos: Estudo transversal realizado com 98 idosos de ambos os sexos, sendo 64 homens e 34 mulheres das regiões Sul e Sudeste do Brasil, e que estavam em isolamento social total ou parcial devido à pandemia de COVID-19 (junho a julho de 2020). Foram utilizados o SARC-F e o Questionário Internacional de Atividade Física (IPAQ), versão curta. A coleta de dados quantitativos ocorreu através de um formulário on-line disponibilizado pela Survey Monkey. Os dados foram analisados por meio dos testes Kolmogorov-Smirnov, Levene, t independente e dependente, e coeficiente de Spearman. Adotou-se significância quando p < 0,05. Resultados: as mulheres (p = 0,047) e os idosos que não praticavam exercício físico (p = 0,001), apresentaram maior tempo sentado após o início da pandemia. Os idosos mais novos (p = 0,002) e que reportaram estar praticando exercício antes do isolamento social (p = 0,006) apresentam menores escores indicativos de sarcopenia durante a pandemia. Os idosos apresentaram aumento nos indicativos de sarcopenia (p = 0,050) e no comportamento sedentário (p = 0,001) durante o período de isolamento social. Conclusão: o período de isolamento social devido à pandemia da COVID-19 provocou aumento no indicativo de sarcopenia e no comportamento sedentário das pessoas idosas.

Objective: to compare whether the indicative of sarcopenia and sedentary behavior increased during social isolation due to the COVID-19 pandemic in elderly Brazilians. Methods: Cross-sectional study conducted with 98 elderly people of both sexes, 64 men and 34 women from southern and southeastern Brazil, and who were in total or partial social isolation due to the COVID-19 pandemic (June to July 2020). The SARC-F and the International Physical Activity Questionnaire (IPAQ), short version, were used. The collection of quantitative data took place through an online form provided by Survey Monkey. Data were analyzed using the Kolmogorov-Smirnov, Levene, independent and dependent t tests, and Spearman's coefficient. Significance was adopted when p < 0.05. Results: women (p = 0.047) and the elderly who did not exercise (p = 0.001) had more time sitting after the onset of the pandemic. Younger elderly (p = 0.002) and those who reported having been exercising before social isolation (p = 0.006) had lower scores indicative of sarcopenia during the pandemic. The elderly showed an increase in sarcopenia indicatives (p = 0.050) and in sedentary behavior (p = 0.001) during the period of social isolation. Conclusion: the period of social isolation due to the COVID-19 pandemic caused an increase in the indicative of sarcopenia and in the sedentary behavior of the elderly.

Questionnaire in Colombian Third-Grade Elementary Schools / Reprodutibilidade do questionário POiBA-(como nos movemos?) em estudantes colombianos da terceira série do ensino fundamental

Introducción: disponer de instrumentos reproducibles que midan la actividad física y los comportamientos sedentarios es una prioridad para la vigilancia y promoción de estilos de vida saludables en niños y niñas. En esta investigación se evaluó la reproducibilidad prueba-reprueba del cuestionario POIBA-¿Cómo nos movemos? en escolares colombianos. Materiales y métodos: participaron 125 estudian- tes de tercer grado de primaria de una institución educativa colombiana. En dos ocasiones se aplicó el cuestionario POIBA-¿Cómo nos movemos?, que evalúa la actividad física realizada para transportarse a la institución educativa y desde esta, durante el tiempo escolar (clases de educación física y recreo), extraescolar (deportiva, con entrenador) y libre. Se emplearon índices kappa y kappa ponderado en los ítems categóricos y el coeficiente de correlación intraclase con modelo de efectos mixtos en los ítems con escala cuantitativa. Resultados: en los ítems sobre actividad física en el ámbito escolar y deportivo predominaron kappas superiores a 0.70. Las preguntas sobre el transporte a la institución educativa y desde esta tuvieron coeficientes kappa cercanos a 0.90. Los ítems de tiempo frente a pantallas alcanzaron coeficientes kappa alrededor de 0.5, y los correspondientes a la hora de acostarse y levantarse obtuvieron coeficientes de correlación intraclase entre 0.40 y 0.72. Conclusiones: el cuestionario POIBA-¿Cómo nos movemos? es una opción para evaluar la actividad física de escolares en el contexto latinoamericano. Los ítems sobre actividad física de transporte, en el ámbito escolar y deportivo, tuvieron los mayores índices de reproducibilidad.

Introduction: Reproducible instruments measuring physical activity and sedentary behaviors are a priority for monitoring and promoting healthy lifestyles for boys and girls. This study evaluated the test-retest reproducibility of the "Prevención de la Obesidad Infantil en Barcelona (Childhood Obesity Prevention in Barcelona) [POIBA]-How do we move?" questionnaire in Colombian school children. Materials and methods: One hundred twenty-five third-grade primary students from a public educational institution in Colombia participated in the "POIBA-How do we move?" questionnaire, which was conducted twice. The survey measured physical activity during travel to and from school, school hours (physical education classes and recess), extracurricular activities (sports with a coach), and leisure time. To assess reproducibility, categorical questions and questions with a quantitative scale were evaluated using kappa and weighted kappa indices and an intraclass correlation coefficient with a mixed-effects model. Results: In the questions about physical activity at school and sports practice, kappas higher than 0.70 predominated. The questions about commuting to and from school had kappa coefficients close to 0.90. The kappa coefficients for the screen-time questions were around 0.5, and the intraclass correlation coefficients for questions about going to bed and getting up were between 0.40 and 0.72. Conclusions: The "POIBA-How do we move?" questionnaire is a valuable tool for evaluating the physical activity of school children in a Latin American context. The questions concerning physical activity during commuting to and from school, school hours, and sports environment had the highest reproducibility indices.

Clustering of cardiovascular disease risk factors among first-year students at the University of Ibadan, Nigeria: a cross-sectional study

ABSTRACT BACKGROUND: Cardiovascular disease (CVD) is the second leading cause of death in sub-Saharan Africa. Globally, there is substantial evidence that modifiable risk factors for CVD are increasing in adolescents. Unfortunately, there is a paucity of information on the prevalence and clustering of these risk factors in adolescents. OBJECTIVES: This study explores the modifiable risk factors for CVD among first-year students at the University of Ibadan, Nigeria. DESIGN AND SETTING: This cross-sectional study was conducted at the University of Ibadan, Nigeria. METHODS: A total of 546 newly admitted students at the University of Ibadan, Nigeria, were recruited using stratified random sampling. An interviewer-administered questionnaire was used to obtain information from study participants between January and February 2016. RESULTS: The mean age of respondents was 19 ± 2.2 years with a male-to-female ratio of 1:1. The reported risk factors for CVD were smoking (1.6%), abdominal obesity (3.3%), alcohol consumption (3.7%), overweight/obesity (20.7%), unhealthy diet (85.3%), and physical inactivity (94.5%). Clustering of ≥ 2 risk factors was reported in 23.4% of students. Female students were twice as probably overweight/obese as male students (adjusted odds ratio [AOR] = 2.2; confidence interval [CI] = 1.41-3.43). Students whose fathers were skilled workers were 3.5 times more likely to be physically inactive (AOR = 1.7; CI = 0.97-2.96). The clustering of ≥ 2 risk factors was significantly higher among women and Muslims in bivariate analysis, whereas no significant association was found in multivariate analysis. CONCLUSIONS: Public health strategies to prevent CVD risk factors should begin in schools and extend to the entire community.
