Association of pre school children physical activities and sedentary behaviors on calcanues bone density / 中国学校卫生

Objective@#To investigate the effects of physical activity (PA) intensity and sedentary behavior (SB) on calcanues bone mineral density (BMD) in preschool children, so as to provide a basis for rationalizing the daily physical activity of preschool children to promote bone health.@*Methods@#A total of 673 pre school children aged 3-6 years from nine kindergartens in Pingxiang City, Ganzhou City and Yingtan City of Jiangxi Province, were selected from September to December 2021 by using the whole stratified cluster random sampling method. The PA levels and SB were measured by using a three axis acceleration sensor, and left calcanues BMD was measured by an ultrasound bone densitometer. Multiple linear regression was used to explore the effects of changes in PA on calcanues BMD in pre school children of all ages.@*Results@#Of the 673 preschoolers surveyed, 498 (74.0%) achieved an average of ≥60 min of moderate to vigorous physical activity (MVPA) per day, there were 265 boys (71.2%), and 233 girls ( 77.4 %). The difference between genders was not statistically significant ( χ 2=2.77, P >0.05). There was no statistically significant difference in the BMD test of the calcaneus bones of preschoolers by gender ( Z=0.42, P >0.05). The difference in BMD results of pre school children with 3, 4, 5 to 6 years was statistically significant ( H=2.65, P <0.05). Correlation analysis revealed a negative correlation between SB duration and calcaneus BMD ( r =-0.13), and a positive correlation between low intensity physical activity (LPA) duration, MVPA duration, and calcaneus BMD ( r =0.14, 0.25 ) ( P <0.05). Multivariate linear regression analysis showed that SB duration negatively correlated with calcaneus BMD, whereas LPA and MVPA duration positively correlated with calcaneus BMD ( P <0.05).@*Conclusions@#MVPA duration is positively correlated with the growth of BMD in the heel bone and negatively correlated with SB. The kindergartens can adjust their curricula according to the physical and mental developmental characteristics, gender and age differences of pre school children, increase the time of outdoor activities, and reduce the sedentary time to promote the bone health of young children.

Establishment of an intervention model for adolescent obesity based on component isochronous substitution method / 中国学校卫生

Objective@#To explore the relationship between isochronous substitution and BMI, waist circumference (WC), and body fat rate (FAT) among physical activity (PA), sedentary (SB), and sleep (SLP), so as to provide effective measures for obesity control in adolescents.@*Methods@#A total of 193 adolescents aged 12-15 (90 males and 103 females) was randomly selected, and their height, weight, and BMI were measured using routine testing methods from May to August 2022. The PA, SB and SLP of the participants were measured using a 3D accelerometer (ActiGraph GT3X+).@*Results@#The arithmetic mean value overestimated SLP (40.8%) and SB (39.6%) to some extent, and underestimated LPA (16.1%) and MVPA (3.5%) to some extent. Based on the ISM at 15 min, MVPA was substituted for other activity, BMI Z decreased by 0.17-0.22 units, WC Z decreased by 0.16-0.20 units, and FAT Z decreased by 0.17-0.22 units. The substitution between MVPA and for other activity exhibited significant asymmetry. The effects of MVPA substitutions for SB was the largest, followed by the effects of MVPA substitutions for SLP, and the effects of MVPA substitutions for LPA was the lowest. As MVPA substitutions for other behaviors, it reached its maximum (0.06-0.08 units ) when the MVPA time increased by 5 minutes.@*Conclusions@#MVPA plays an irreplaceable role in the control of adolescent obesity . While reducing SB time, MVPA duration should be increased to ensure that the daily MVPA duration is not less than 55 minutes in order to effectively control obesity.

Correlation between handgrip strength and pulmonary function in college students / 中国学校卫生

Objective@#To explore the relationship between handgrip strength (HGS) and pulmonary function (PF) in college students with sedentary lifestyle, so as to provide a reference for taking HGS as an essential factor of PF.@*Methods@#In March 1-5, 2023, a total of 44 college students were recruited and were divided into the sedentary group (22) and exercise group (22) according to the International Physical Activity Questionaire (IPAQ), with 22 students in each group. Independent sample t-test was used to compare the indexes between groups, pearson correlation coefficient was used to determine the correlation between HGS and PF. Multiple linear regression analysis was used to determine the predictive model of PF.@*Results@#There were statistical significance of the correlations between HGS and FVC, MEP, PEF, FEV1, FIVC, MIP, and PIF ( r=0.79, 0.47, 0.44, 0.60, 0.72, 0.53 , 0.49, P <0.01). When gender, physical activity, age, height, weight, and HGS were included as predictors in the regression model, height and HGS had significant effects on FVC ( R 2=0.75, F= 60.55 , P <0.01), weight and HGS had a good predictive effect on FIVC ( R 2=0.67, F=41.77, P <0.01).@*Conclusion@#HGS is significantly associated with PF in college students with sedentary lifestyle. Therefore, HGS can be used as an important indicator to predict the PF status of habitual sedentary college students.

Besides this physical activity, consumption of junk/fast foods along with watching TV and video games along with mother education and occupation were significantly associated with overweight and obesity in children抯 and adolescents.Conclusions:Having overweight parents along with limited exercise and Sedentary activities along with physical inactivity compounded by erratic eating habits with overweight parents are main risk factors leading to overweight and obesity in school going children抯 and adolescents in north Kashmir, India.

Prevalence of metabolic syndrome in urban low socioeconomic group patients with symptomatic coronary artery disease

Introduction: Sedentary lifestyle, low fiber, high fat and energy-rich foods have penetrated even the rural India in the name of globalization. All these will come not without cost. India is now facing the paradox of malnutrition on one hand and epidemic of obesity on the other. Indians three times higher risk of developing Coronary Artery Disease (CAD) compared to Chinese and are 20 times more likely to die due to CAD compared to native black or white South Africans. The aim of the study: To find out the prevalence of Central Obesity, Hypertension, Impaired Fasting Glucose or Diabetes mellitus, Hypertriglyceridemia and low HDL cholesterol and to analyze the differences in their prevalence among the age groups, sex, social class and chronic and acute coronary syndromes. Materials and methods: All patients belonged to a low socioeconomic group attended medical outpatient department or those who were getting admitted medical ward of Govt. Dharmapuri Medical College, Dharmapuri with coronary artery disease (CAD) were included. Results: Mean of age for males (CI: 55.49± 22years) and females (CI: 51.87±24.7years) lied within one standard deviation from the sample mean. 59 patients (52.2%) had central obesity. 64.2% patients in age group <40 years, 41.4% in age group 40-60 years and 72.4% in age group >60 years had central obesity. This increase in the prevalence of central obesity among younger (<40 year) and older age group (>60 years) was significant. 84 patients (74.34%) had hypertension. 71.43% patients in age group <40 years, 77.14% in age group 40-60 years and 68.96% in age group >60 years had hypertension. There was no significant difference in prevalence of hypertension among age group.57 patients (50.44%) had diabetes or IFG. 50% patients in age group <40 years, 40% in age group 40-60 G. Indhumathi, K. Suresh Kumar. Prevalence of metabolic syndrome in urban low socioeconomic group patients with symptomatic coronary artery disease. IAIM, 2018; 5(3): 15-22. Page 16 years and 75.86% in age group >60 years had diabetes or IFG. This increase in the prevalence of Diabetes and IFG among younger (<40 year) and older age group (>60 years) was significant. 48 patients (42.48%) had hypertriglyceridemia. 50% patients in age group <40 years, 32.86% in age group 40-60 years and 62% in age group >60 years had hypertriglyceridemia. 54 patients (47.78%) had metabolic syndrome. 50% patients in age group <40 years, 37.14% in age group 40-60 years and 72.41% in age group >60 years had metabolic syndrome. This increase in the prevalence of metabolic syndrome among younger (<40 year) and older age group (>60 years) is significant (X 2 - 10.25, p=.006). Conclusion: The result of the present study suggests that in urban patients who live below poverty line with symptomatic coronary artery disease there in the increased prevalence of metabolic syndrome, central obesity, hyperglycemia, hypertension, and dyslipidemia. The higher prevalence particularly noticeable in those with the premature coronary artery disease and that might have resulted in earlier onset of CAD in them.

Deslocamento passivo para escola e fatores associados em adolescentes / Passive commuting to school and associated factors among adolescents

RESUMO O presente estudo objetivou estimar a prevalência do deslocamento passivo para escola e os fatores associados em adolescentes (14-19 anos) do ensino médio de escolas públicas e particulares do município de Uberaba, MG, Brasil. Um total de 1.009 adolescentes participaram deste estudo transversal epidemiológico de base escolar. O desfecho do estudo foi o deslocamento passivo (motocicleta, carro e ônibus) e as variáveis exploratórias sociodemográficas (sexo, idade, situação de trabalho, série e turno de estudo), perceptiva e comportamentais (apreciação por atividade física, comportamento de tela e atividade física no lazer) e de saúde (IMC). O Odds Ratio (OR) foi a medida de associação empregada nas análises. O deslocamento passivo foi prevalente em 58,3% (IC95%: 55,2-61,4) dos adolescentes e foi associado ao sexo feminino (OR: 1,82; IC95%: 1,32-2,51), aqueles do 3º ano do ensino (OR: 1,67; IC95%: 1,07-2,61) e aos menos ativos no lazer (OR: 1,44; IC95%: 1,03-2,01). Por outro lado, estudar em escolas públicas apresentou menor associação (OR: 0,16; IC95%: 0,10-0,26). O deslocamento passivo para escola foi prevalente em mais da metade dos adolescentes investigados e está associado as moças, ao grau mais elevado de escolaridade e ao menor envolvimento com a atividade física no lazer.

ABSTRACT The aim of this study was to estimate the prevalence of the passive commuting to school and associated factors among adolescents (14-19 years) of public and private schools from Uberaba, MG, Brazil. A total of 1009 adolescents participated of this epidemiological transversal study. The outcome of the study was the passive commuting (motorcycle, car and bus) and exploratory variables were socio-demographic (sex, age, labor status, grade and study shifts), perceptive and behavioral (physical activity appreciation, screen behavior and leisure physical activity) and health (BMI). The Odds Ratio (OR) was the association measure employed in the analyses. Passive commuting was prevalent in 58.3% (IC95%: 55.2-61.4) of the adolescents and it was associated with female sex (OR: 1.82; IC95%: 1.32-2.51), 3rd series of education (OR: 1.67; IC95%: 1.07-2.61) and to less actives in leisure (OR: 1,44; IC95%: 1,03-2,01). On the other hand, to study in public schools was less associated (OR: 0.16; IC95%: 0.10-0.26). The passive commuting for school was prevalent in more than half of the adolescents and is associated with the female sex, last school series, as well as the less active life style in the leisure.

Percepção de regras e de confiança em reduzir o tempo de tela em adolescentes / Rules perception and confidence in the ability to reduce screen time in adolescents

O objetivo deste estudo foi analisar a associação entre o tempo de tela com a percepção de regras e a confiança em reduzir o tempo de tela em adolescentes. Participaram 358 adolescentes (58,2% meninas), entre 14 e 18 anos, da cidade do Porto - Portugal. A percepção de regras e a confiança em reduzir o tempo de tela foram avaliadas por medidas autorreportadas através de instrumentos validados para esta população. Os adolescentes que percebem alguma regra por parte dos pais apresentam menor prevalência de exposição ao tempo de tela ( 2 horas/dia) para uso da internet (RP=0,62; IC95%: 0,28-0,99). A moderada (RP=0,60; IC95%: 0,34-0,99) ou elevada (RP=0,51; IC95%: 0,27-0,96) confiança na capacidade de reduzir o tempo de tela foi associado de forma inversa com a prevalência de não cumprir as recomendações do tempo de tela para assistir TV e usar vídeo game/computador. A percepção de regras e moderada ou elevada confiança na capacidade de reduzir o tempo de tela foram associados com menor proporção de adolescentes expostos a atividades sedentárias, tais como assistir TV e usar internet por +- 2 horas/dia.

The aim of this study was examine the association between screen time with rules perception and confidence to reduce screen time in adolescents. Data were obtained from 358 adolescents (58.2% girls) aged between 14 and 18 years old in the city of Porto - Portugal. To evaluate the amount time in screen time activities, as well as the confidence and rules perception we used validated self-reported surveys. Adolescents who perceived some rule have less likelihood to screen time ( 2 hours/day) for Internet use (PR = 0.62; 95% IC: 0.28 to 0.99). The moderate (RP= 0.60; 95% IC 0.34 to 0.99) or high (RP = 0.51; 95% IC: 0.27 to 0.96) confidence in the ability to reduce screen time was associated inversely with prevalence to meet the recommendations of screen time to watch TV and play video game/computer. There was an association in the capacity to reduce screen time between adolescents who perceive some rules and showed moderate to high confidence and the exposed time sedentary activities, such as, watching TV and Internet utilization for more +- 2 hours/day.

Prática de atividade física entre pacientes da Coorte Brasília de artrite reumatoide inicial / Physical activity among patients from the Brasília cohort of early rheumatoid arthritis

INTRODUÇÃO: O Consenso 2012 da Sociedade Brasileira de Reumatologia para Tratamento da Artrite Reumatoide (AR) recomenda que os pacientes realizem exercícios físicos de forma regular. Não há estudos no Brasil sobre a prática de atividade física entre pacientes com AR inicial. OBJETIVO: Investigar a prática de atividade física entre pacientes com AR inicial e a possível relação entre atividade física, atividade da doença e incapacidade funcional. MÉTODOS: Estudo transversal incluindo pacientes da Coorte Brasília de AR inicial. Foram analisados dados demográficos (sexo, idade e escolaridade), prática de atividade física, índice de atividade da doença (Disease Activity Score 28 - DAS 28), incapacidade funcional (Health Assessment Questionnaire - HAQ), além de dados sobre tabagismo, etilismo, presença de comorbidades e tratamento da AR. RESULTADOS: Foram avaliados 72 pacientes, sendo 90,27% do sexo feminino, com média de idade de 50,2 ± 13,3 anos, média do DAS 28: 3,66 e a do HAQ: 0,69. Estavam regularmente ativos 43,05%, sendo que a caminhada foi o exercício mais praticado (80,64%). A média de tempo de exercício físico foi de 48,22 ± 27,18 min, periodicidade de 3,7 ± 1,64 vezes na semana. Não houve associação entre atividade física com sexo, idade, escolaridade, atividade da doença, incapacidade funcional, tabagismo ou etilismo, presença de comorbidades e tratamento com drogas modificadoras do curso da doença. CONCLUSÃO: Dada a importância da prática regular de atividade física, há necessidade de orientação dos pacientes, em especial quanto à prática de atividades resistidas, pouco frequente entre os pacientes do nosso estudo.

INTRODUCTION: The 2012 Consensus of the Brazilian Society of Rheumatology (SBR) for the treatment of Rheumatoid Arthritis (RA) recommends that patients should regularly perform physical exercises. There have been no studies in Brazil on physical activity among patients with early RA. OBJECTIVE: To investigate the physical activity practice among patients with early RA and the possible association between physical activity, disease activity and functional disability. METHODS: Cross-sectional study of patients from the Brasilia cohort of early RA. Demographic data (sex, age and level of schooling), physical activity practice, Disease Activity Score 28 (DAS 28), functional disability (Health Assessment Questionnaire - HAQ), as well as data on smoking status, alcohol consumption, comorbidities and RA treatment were analyzed. RESULTS: A total of 72 patients were evaluated, 90.27% females, mean age 50.2 ± 13.3 years, mean DAS 28: 3.66 and HAQ: 0.69. Of them, 43.05% were regularly active, with walking being the most often practiced exercise (80.64%). The mean duration of exercise was 48.22 ± 27.18 min, with a frequency of 3.7 ± 1.64 times per week. There was no association between physical activity and gender, age, educational level, disease activity, functional disability, alcoholism or smoking, presence of comorbidities and treatment with drugs that alter the course of disease. CONCLUSION: Given the importance of regular physical activity practice, it is necessary to recommend it to patients, especially resistance physical activities, which are not frequent among the patients in our study.

Intervenciones dirigidas a disminuir/evitar el sedentarismo en los escolares / Interventions Aimed to Lower/Avoid Sedentarism in Scholars

Introducción. La obesidad tiene un origen multifactorial, uno de estos factores es la inactividad física o sedentarismo, que en conjunto con otros y a largo plazo predisponen al deterioro de la salud en general, con lo que la población infantil ya está lidiando. Los hábitos activos o sedentarios adquiridos en la infancia y la adolescencia tienden a persistir en la edad adulta. Objetivo. Identificar publicaciones, en bases de datos especializadas, sobre programas de intervención que han tenido buenos resultados para disminuir o limitar el sedentarismo en escolares. Metodología. Se realizó una búsqueda en las bases de datos Medline y Redalyc de artículos publicados durante los últimos 5 años, relacionados con intervenciones enfocadas a fomentar el ejercicio físico en escolares de 6 a 12 años. Los descriptores utilizados fueron: Sedentary, childrens and sedentary, physical inactivity. De 326 artículos que arrojaron las bases de datos, se eligieron 35 por su estrecha relación con este tema. Resultados. Hay diversas razones por las que los escolares no realizan Ejercicio Físico, entre ellas está la forma de vida que los padres de familia ofrecen a sus hijos. El buen hábito de la vida activa es influenciado por el espacio y ambiente en que los niños se desarrollan. Conclusiones. Se debe prestar mayor atención a los escolares, en todas sus actividades; alimentación, tiempo que pasan fuera de casa o solos, es necesario re ubicar o reafirmar los hábitos de vida que están adquiriendo los escolares durante su desarrollo ya que los seguirán por el resto de su vida.

Introduction: Physical inactivity is one of obesity's factors, and this problem, which in the long term impairs health in general, is already found in infantile populations whose sedentary habits tend to persist through out adulthood. Objective: to address publications on successful intervention programs in lowering or limiting sedentarism in scholars. Methodology; a Medline and Redalyc database search was performed on the last five years using the key words sedentary, children, and physical inactivity. From 326 articles located, 35 were finally kept. Results: there were several reasons to explain children's inactivity including the life-style which their parents teach them, and the space or ambience in which they grow. Conclusions: More attention should be given to scholars in their activities, nutrition, and time spent at home. It is necessary to generate good life habits which children will follow for the rest of their lives.
