Sobrepeso y obesidad en infancias de Bariloche, Argentina: más allá de la alimentación y la actividad física / Childhood overweight and obesity in Bariloche, Argentina: Beyond eating habits and physical activity

La incidencia de sobrepeso y obesidad es alarmante en el mundo. En Argentina son escasos los estudios multifactoriales a pesar de los altos índices de sobrepeso y obesidad en la población infantil (SOI). En este estudio evaluamos la prevalencia de SOI y sus factores de riesgo asociados desde una perspectiva multicausal: analizamos hábitos de sueño, uso de pantallas, estrés crónico en niños y sus cuidadores, problemas de relación social, alimentación y actividad física. De los 397 niños de primer y séptimo grado que completaron los cuestionarios, el 41 % presentó SOI. Los niños con obesidad mostraron realizar menos actividad física, tener un menor consumo de alimentos protectores, más riesgos de trastornos del sueño, mayores niveles de estrés crónico (tanto en los niños como en sus cuidadores) y mayor índice de rechazo entre pares. En la mayoría de los niños se encontró un uso generalizado de pantallas antes de acostarse. El presente estudio evidencia la diversidad de factores asociados a esta problemática y destaca la conveniencia de utilizar un enfoque multidimensional para abordar la obesidad en la infancia. Asimismo, los resultados de este trabajo sugieren la necesidad de considerar los hábitos de vida como estrategia preventiva y terapéutica para el tratamiento de esta enfermedad desde etapas tempranas.

The incidence of overweight and obesity is alarming worldwide. In Argentina, multifactorial studies are scarce despite the high rates of childhood overweight and obesity (OW/OB). In this study we assessed the prevalence of childhood OW/OB and the associated risk factors from a multicausal perspective: we analyzed sleep habits, screen use, chronic stress in children and their caregivers, social relationship problems, eating habits, and physical activity. Of the 397 first and seventh graders who completed the questionnaires, 41% had childhood OW/OB. In children with obesity, a lower level of physical activity, a lower consumption of protective foods, a higher risk for sleep disorders, higher levels of chronic stress (in both children and their caregivers), and higher rates of peer rejection were observed. Widespread use of screens before bedtime was noted in most children. This study evidences the diversity of factors associated with childhood OW/OB and highlights the convenience of a multidimensional approach to address it. In addition, the results of this study suggest the need to consider lifestyle habits as a preventive and therapeutic strategy for the management of OW/OB from early stages.

Percentiles de peso, talla e índice de masa corporal de escolares de Mendoza. Comparación con la referencia de la Organización Mundial de la Salud / Body mass index, weight, and height percentiles in school-aged children from Mendoza. A comparison with the WHO reference

Introducción. La Organización Mundial de la Salud (OMS) recomienda el uso de tablas de referencia para monitorear el crecimiento y estado nutricional de niños, niñas y adolescentes. El peso corporal, la talla y el índice de masa corporal (IMC) son las variables más utilizadas. El presente trabajo tiene como objetivos estimar los percentiles de peso, talla e IMC de escolares (2009-2011) residentes en el departamento San Rafael (Mendoza) y compararlos con la referencia internacional de la Organización Mundial de la Salud, a fin de establecer su pertinencia para la evaluación del crecimiento y estado nutricional de dicha población. Población y métodos. Se realizó un estudio antropométrico transversal en 3448 escolares de entre 4,00 y 13,49 años de edad. Se utilizó el programa LMS ChartMarker Pro para calcular los valores percentilares de peso/edad, talla/edad e IMC/edad, por sexo y edad, y se compararon con las curvas de la OMS. Además, se calcularon diferencias porcentuales (D%) para estimar las diferencias y su significación estadística mediante prueba de Wilcoxon. Resultados. La población de San Rafael mostró, en varones y mujeres, valores percentilares superiores de peso e IMC (D% ≈7 % y 9 %, respectivamente), y menores de talla (D% ≈0,8 %) que los de la OMS (p <0,05). Conclusión. Las diferencias encontradas alertan sobre el empleo de la referencia OMS en la población escolar de San Rafael, ya que sobreestimaría las prevalencias de sobrepeso, obesidad y desnutrición crónica, y subestimaría la de desnutrición aguda y global. Esta situación resalta la importancia de contar con una referencia local.

Introduction. The World Health Organization (WHO) recommends the use of reference tables to monitor the growth pattern and nutritional status of children and adolescents. Body mass index (BMI), weight, and height are the most commonly used variables. The objective of this study was to estimate the BMI, weight, and height percentiles for school-aged children (2009-2011) living in the department of San Rafael (Mendoza) and compare them to the international World Health Organization reference to establish their relevance for the evaluation of the growth pattern and nutritional status of this population. Population and methods. A cross-sectional anthropometric study was conducted in 3448 school-aged children aged 4.00 to 13.49 years. The LMS ChartMarker Pro software was used to estimate the BMI- for-age, weight-for-age, and height-for-age percentiles, by sex and age, and they were compared with the WHO curves. Besides, percentage differences (%D) were calculated to estimate the differences and their statistical significance using the Wilcoxon test. Results. The population of boys and girls in San Rafael showed higher weight and BMI (%D ≈ 7% and 9%, respectively) percentiles, and lower height (%D ≈ 0.8%) values than WHO reference (p < 0.05). Conclusion. The differences found warn about the use of the WHO reference in the school-aged population of San Rafael since it would overestimate the prevalence of overweight, obesity, and chronic malnutrition and underestimate the prevalence of acute and global malnutrition. This situation highlights the importance of having a local reference resource

Overweight in Sateré-Mawé indigenous residents of an urban area in Parintins, Amazonas / Sobrepeso em indígenas Sateré-Mawé residentes em área urbana de Parintins, Amazonas

ABSTRACT Objective To verify overweight prevalence in the Sateré-Mawé indigenous population over 18 years of age, residing in the city of Parintins (AM), Brazil, and to assess its associated variables. Methods Household survey performed in the urban area of Parintins in 2017, visiting new households in each interview, completing the census universe. Self-declared Sateré-Mawé, over 18 years of age, residing in the city for a period longer than one year were considered eligible. Overweight was considered for body mass index values ≥ 25 kg/m2 or ≥ 27 kg/m2, for those over 60 years of age. Household information on social assistance, as well as individual information such as speaking the indigenous language, years living in the city and also in the indigenous territory, income, work, schooling, marital status, leisure and transport physical activity level, and time watching television per week were retrieved. The hierarchical logistic model analysis was carried out, calculating the odds ratio and confidence interval (95%). Results A total of 174 subjects participated in the survey, 42% being overweight. Those who spoke the Sateré-Mawé language, number of years living in the city, working outside home and being married had a positive effect on the outcome, but lost significance in the final model. Only transport insufficient physical activity (OR=2.24, 95% CI=1.01-4.98) and being in the age group from 30 to 59 years (OR=8.79, 95% CI=3.41-22.64) maintained statistical significance. Conclusion Efforts to provide visibility to the health situation of urban indigenous populations in Brazil are necessary. Poor transport infrastructure in the city seems to favor transport physical activity levels as a necessity, in addition to age, which is commonly associated with overweight.

RESUMO Objetivo Verificar a prevalência de sobrepeso em indígenas Sateré-Mawé maiores de 18 anos de idade, residentes na cidade de Parintins (AM), Brasil, identificando as variáveis associadas. Métodos Um inquérito domiciliar foi realizado em 2017 na cidade de Parintins e identificou novos domicílios em cada entrevista, alcançando o universo censitário. Foram elegíveis os autodeclarados Sateré-Mawé maiores de 18 anos e residentes há mais de um ano na cidade. O sobrepeso foi considerado para valores de índice de massa corporal ≥25 kg/m2 ou ≥27 kg/m2 para os maiores de 60 anos de idade. Coletou-se informações domiciliares sobre bolsa família, bem como individuais como falar a língua indígena, anos morando na cidade e na terra indígena, renda, trabalho, escolaridade, estado civil, nível de atividade física no lazer e no deslocamento e tempo assistindo televisão na semana. Foi utilizado o modelo logístico hierarquizado, calculando a razão de chances e intervalo de confiança (95%). Resultados Participaram do estudo 174 pessoas no total, sendo que 42% deles estavam com sobrepeso. Falar a língua Sateré-Mawé, a quantidade de anos residindo na cidade, trabalhar fora de casa e ser casado tiveram efeito positivo no desfecho, porém perderam significância no modelo final. Somente atividade física insuficiente no deslocamento (OR=2,24 IC 95%=1,01-4,98) e a faixa etária dos 30 a 59 anos (OR=8,79 IC 95%=3,41-22,64) mantiveram-se significativas. Conclusão Esforços para dar visibilidade à situação de saúde das populações indígenas urbanas no Brasil são necessários. A fraca infraestrutura de transporte na cidade parece favorecer a atividade física no deslocamento como necessidade, além da idade, já comumente associada ao sobrepeso.

Influencia de la seropositividad contra adenovirus-36 sobre riesgo de obesidad y resistencia a la insulina en población infanto-juvenil de la Región de la Araucanía / Influence of adenovirus 36 seropositivity on the risk of obesity and insulin resistance in a population of children and adolescents from the Región de la Araucanía

La infección previa por el adenovirus-36 (Ad-36) se ha asociado con el proceso adipogénico y el control glicémico en modelos experimentales de cultivos celulares y animales. En humanos, la presencia de anticuerpos contra Ad-36 ha mostrado aumentar el riesgo de obesidad y, paradójicamente, mejorar el control glicémico en diferentes poblaciones. Se evaluó la influencia de la seropositividad contra Ad-36 sobre riesgo de obesidad, el perfil lipídico y glicémico en una población de niños en edad escolar. Métodos: Doscientos ocho individuos de entre 9 y 13 años se agruparon según estado nutricional como normopeso (IMC z-score de -1 a +1), con sobrepeso (IMC z-score de +1 a +2) y con obesidad (IMC z-score > +3). Se evaluaron medidas antropométricas, desarrollo puberal según Tanner y parámetros bioquímicos (perfil lipídico, glucemia e insulina) y la seropositividad contra Ad-36. Se determinó la resistencia a la insulina (RI) según criterio para la población infantil chilena. La seropositividad contra Ad-36 se determinó mediante ELISA. Resultados: Hubo una alta prevalencia de sobrepeso/obesidad en la población de estudio. La seropositividad contra Ad-36 fue del 5,4% en el grupo total, pero no se observó una asociación con el estado nutricional. No se encontró correlación entre la seropositividad contra Ad-36 y los parámetros del perfil lipídico. La insulina y la HOMA-RI fueron significativamente más bajas en el grupo Ad-36 (+) (p<0,001), no habiendo sido reportados casos de RI en el grupo Ad-36 (+) en nuestra población. Conclusiones: Nuestros resultados sugieren que la infección previa por el adenovirus-36 afecta la secreción de insulina y la resistencia a la insulina, como se ha descrito anteriormente, sin embargo, no se observa correlación con el desarrollo de la obesidad infantil en la población pediátrica del sur de Chile.

Previous infection with Adenovirus-36 (Ad-36) has been associated with adipogenic process and glycemic control in experimental models of cell culture and animals. In humans, the presence of antibodies against Ad-36 has been shown to increase the risk of obesity and, paradoxically, improve glycemic control in different populations. The influence of Ad-36 seropositivity on obesity risk, lipid and glycemic profile was evaluated in a population of school-age children. Methods: Two hundred eight individuals aged 9 to 13 years were grouped according to their nutritional status as normal weight (BMI z-score from -1 to +1), overweight (BMI z-score from +1 to +2) or obese (BMI z-score from -1 to +1). z-score > +3). Anthropometric measurements, pubertal development according to Tanner stage, biochemical parameters (lipid profile, glycemia and insulin) and seropositivity against Ad-36 were evaluated. Insulin resistance (IR) was determined according to criteria for the Chilean child population. Seropositivity against Ad-36 was determined by ELISA. Results: There was a high prevalence of overweight/obesity in the study population. Seropositivity against Ad-36 was 5.4% in the total group, but no association with nutritional status was observed. No correlation was found between Ad-36 seropositivity and lipid profile parameters. Insulin and HOMA-RI were significantly lower in the Ad-36 (+) group (p<0.001), and no cases of RI were reported in the Ad-36 (+) group in our population. Conclusions: Our results suggest that previous adenovirus-36 infection affects insulin secretion and insulin resistance, as previously described, however, no correlation is observed with the development of childhood obesity in the pediatric population. from southern Chile.

Food practices and nutritional status of university students who use the University Restaurant / Práticas alimentares e o estado nutricional entre estudantes universitários usuários do Restaurante-Escola

ABSTRACT Objective To evaluate the food practices and nutritional status of students who use the University Restaurant at a public university. Methods This is a cross-sectional study carried out with 958 university students. Data related to regular eating practices (≥5 times/week), routine food consumption and nutritional status were collected. The association between University Restaurant attendance and dietary practices and body mass index was reviewed by bivariate logistic regression model and multiple regression. Results Students who attended the University Restaurant three or more times a week were more likely to regularly consume beans (OR: 1.35, p=0.041) and fresh salad (OR: 1.77, p<0.001) and less likely to have afternoon snack (OR: 0.68; p=0.008). In addition, an association between soda consumption and overweight was observed. Conclusion Thus, the importance of strategies that seek to promote incentives for healthy eating and lifestyle practices in the university population become evident.

RESUMO Objetivo O objetivo do estudo foi avaliar as práticas alimentares e o estado nutricional de estudantes usuários do restaurante-escola em uma universidade pública. Métodos Trata-se de um estudo transversal realizado com 958 estudantes universitários. Foram coletados dados relacionados às práticas alimentares regulares (≥5 vezes/semana), à rotina alimentar e ao estado nutricional. A associação entre a frequência de ida ao restaurante-escola, práticas alimentares e índice de massa corporal foi analisada por modelo de regressão logística bivariada e regressão múltipla. Resultados Os estudantes que frequentaram o restaurante-escola 3 ou mais vezes por semana apresentaram maiores chances de consumir regularmente feijão (OR: 1,35, p=0,041) e salada crua (OR: 1,77, p<0,001) e menos chances de realizar o lanche da tarde (OR: 0,68; p=0,008). Além disso, foi observada associação entre o consumo de refrigerante e o excesso de peso. Conclusão Dessa forma, evidencia-se a importância de estratégias que busquem promover incentivos a práticas alimentares e de vida saudáveis na população universitária.

A case-control study on the association between a healthy lifestyle and obesity among adult twins in Shanghai / 中华流行病学杂志

Objective: To investigate the associations between the numbers of healthy lifestyles and overweight/obesity and abdominal obesity in adult twins in Shanghai. Methods: Based on the Shanghai Twin Registry System Phase Ⅱ survey data in 2017-2018, a case-control study was conducted to analyze the association between healthy lifestyles and obesity and further adjusted for confounders by a co-twin control study. Results: A total of 7 864 adult twins (3 932 pairs) were included. In the co-twin case-control analysis for monozygotic twins, compared with participants with 0 to 2 healthy lifestyles, those with 3 and 4 to 5 healthy lifestyles had a 49% (OR=0.51, 95%CI: 0.28-0.93) and 70% (OR=0.30, 95%CI: 0.13-0.69) lower risk of overweight/obesity, respectively, and a 17% (OR=0.83, 95%CI: 0.44-1.57) and 66% (OR=0.34, 95%CI: 0.14-0.80) lower risk of abdominal obesity, respectively. For each additional healthy lifestyle, the risk of developing overweight/obesity was reduced by 41% (OR=0.59, 95%CI: 0.42-0.85), and the risk of developing abdominal obesity was reduced by 37% (OR=0.63, 95%CI: 0.44-0.90). Conclusion: An increasing number of healthy lifestyles was associated with a marked decreased risk for both overweight/obesity and abdominal obesity.

Objective: To explore the obesity-related factors among primary and middle school students in Hangzhou. Methods: A stratified random cluster sampling cross-sectional study was conducted using Hangzhou city's 2016-2020 annual school health survey data. Finally, 9 213 primary and secondary school students with complete data were selected as the research objects. The standard of Overweight and Obesity Screening for School-age Children and Adolescents (WS/T 586-2018) was used to verify students' obesity. SPSS 25.0 software was applied to conduct statistical analysis on the related factors of obesity. Results: The overall obesity detection rate among primary and middle school students in Hangzhou was 8.52%. The results of logistic regression analysis showed that inadequate sleep (OR=6.507, 95%CI: 2.371-17.861, P<0.001), 3- hours (OR=5.666, 95%CI: 2.164-14.835, P<0.001) and ≥4 hours (OR=7.530, 95%CI: 2.804-20.221, P<0.001) of watching video every day in the past week, being beaten and scolded by parents in the past week (OR=1.627, 95%CI: 1.161-2.280, P=0.005), parents often reduce students' exercise time in order to let students have more time to study in the past week (OR=3.310, 95%CI: 1.243-8.819, P=0.017), age 16-18 years old (OR=0.137, 95%CI: 0.050-0.374, P<0.001), often suffering from campus violence in the past week (OR=0.332, 95%CI: 0.141-0.783, P=0.012), 1 hour of watching video every day in the past week (OR=0.023, 95%CI: 0.006-0.083, P<0.001), sometimes having breakfast (OR=0.151, 95%CI: 0.058-0.397, P<0.001) and eating breakfast every day (OR=0.020, 95%CI: 0.005-0.065, P<0.001) in the past week, eating vegetables and fruits sometimes (OR=0.015, 95%CI: 0.010-0.023, P<0.001) and every day (OR=0.020, 95%CI: 0.008-0.053, P<0.001) in the past week, eating sweet food sometimes (OR=0.089, 95%CI: 0.035-0.227, P<0.001) and every day (OR=2.568, 95%CI: 1.632-4.041, P<0.001) in the past week, eating fried food sometimes (OR=0.274, 95%CI: 0.094-0.800, P=0.018) in the past week, and having three physical education classes every week (OR=0.156, 95%CI: 0.057-0.423, P<0.001) were the main related factors affecting the occurrence of obesity in primary and secondary school students. Conclusions: With the higher obesity prevalence among primary and middle school students in Hangzhou, parents and teachers should strengthen health education for primary and middle school students, help children develop scientific eating behavior, develop positive and healthy living habits of children, and effectively prevent overweight/obesity in primary and middle school students.

Analysis of incidence and associated factors of preterm birth based on pre-pregnancy body mass index stratification / 中华预防医学杂志

Objective: To analyze the incidence of preterm birth based on pre-pregnancy body mass index (BMI) stratification and explore the associated factors of preterm birth among pregnant women at different BMI stratifications. Methods: From February 2018 to December 2020, pregnant women who participated in China Birth Cohort Study (CBCS) and gave birth at Beijing Obstetrics and Gynecology Hospital were enrolled as the study subjects. Electronic Data Capture System and standard structured questionnaires were used to collect data related to pre-pregnancy, pregnancy, and delivery for pregnant women. Pregnant women were divided into the low-weight group, normal-weight group and overweight group based on their pre-pregnancy BMI. A Cox proportional hazards model was used to analyze the associated factors of preterm birth among pregnant women with different BMI before pregnancy. Results: A total of 27 195 singleton pregnant women were included, with a preterm birth rate of 5.08% (1 381/27 195). The preterm birth rates in the low-weight group, normal-weight group and overweight group were 4.29% (138/3 219), 4.63% (852/18 390) and 7.00% (391/5 586) respectively (P<0.001). After adjusting for relevant factors, the Cox proportional hazards model showed that the risk of preterm birth in the overweight group was 1.457 times higher than that in the normal-weight group (95%CI: 1.292-1.643). Preeclampsia-eclampsia (HR=2.701, 95%CI: 1.318-5.537) was the associated factor for preterm birth in the low-weight group. Advanced maternal age (HR=1.232, 95%CI: 1.054-1.441), history of preterm birth (HR=4.647, 95%CI: 3.314-6.515), vaginal bleeding in early pregnancy (HR=1.613, 95%CI: 1.380-1.884), and preeclampsia-eclampsia (HR=3.553, 95%CI: 2.866-4.404) were associated factors for preterm birth in the normal-weight group. Advanced maternal age (HR=1.473, 95%CI: 1.193-1.818), history of preterm birth (HR=3.209, 95%CI: 1.960-5.253), vaginal bleeding in early pregnancy (HR=1.636, 95%CI: 1.301-2.058), preeclampsia-eclampsia (HR=2.873, 95%CI:2.265-3.643), and pre-gestational diabetes mellitus (HR=1.867, 95%CI: 1.283-2.717) were associated factors for preterm birth in the overweight group. Conclusion: Pre-pregnancy overweight is an associated factor for preterm birth, and there are significant differences in the associated factors of preterm birth among pregnant women with different BMI before pregnancy.

Overweight/obesity in college students: a systematic review / Excesso de peso/obesidade em estudantes universitários: uma revisão sistemática / Sobrepeso/obesidad en estudiantes universitarios: una revisión sistemática

This article aims to characterize the prevalence and the factors associated with overweight/obesity in college students, through a systematic review. For doing so, the PRISMA protocol has been utilized. Articles about overweight/obesity were selected in college students on the databases of the National Library of Medicine (PUBMED), Scientific Electronic Library Online (SciELO), Biblioteca Virtual em Saúde (BVS), Web of Science and Scopus, it was considered the publication period from 2014 to 2019. We found 4,740 articles and 28 met the eligibility criteria. The overweight/obesity prevalence in college students varied from 9.5% to 47.0%. The Odds Ratio was the most used association measure (comparison) in studies. As characteristics that favor overweight/obesity, inadequate diet, income, male gender, low level of physical activity and family history of overweight/obesity are mentioned. The factors associated with protection against overweight/obesity were a healthy diet, regular physical activity and screen time. Finally, this review showed that university students are prone to overweight/obesity, as they have behavioral factors related to inadequate diet, low level of physical activity, income, being male, and sociocultural and family aspects due to a history of overweight/obesity. In counterpart, this review argues that healthy diet and physical activity and reduced screen time represent a health maintenance factor against overweight/obesity.

Este artigo tem como objetivo caracterizar a prevalência e os fatores associados ao sobrepeso/obesidade em universitários, por meio de uma revisão sistemática. Para isso, foi utilizado o protocolo PRISMA. Foram selecionados os artigos sobre sobrepeso/obesidade de universitários nas bases de dados da National Library of Medicine (PUBMED), Scientific Electronic Library Online (SciELO), Biblioteca Virtual em Saúde (BVS), Web of Science e Scopus, considerou-se o período de publicação de 2014 a 2019. Dos 4.740 artigos encontrados, 28 atenderam aos critérios de elegibilidade. A prevalência de sobrepeso/obesidade em universitários variou de 9,5% a 47,0%. Dentre as medidas de associação (comparação), houve maior utilização do Odds Ratio. Como destaques os fatores associados com o sobrepeso/obesidade, cita-se a dieta inadequada, renda, sexo masculino, baixo nível de atividade física e o histórico familiar de sobrepeso/obesidade. Os fatores associados como proteção ao sobrepeso/obesidade foram a dieta saudável, prática regular de atividade física e o tempo de tela. Por fim, esta revisão mostrou que os universitários são propensos ao sobrepeso/obesidade, por apresentarem fatores comportamentais relacionados a dietas inadequadas, baixo nível de atividade física, renda, ser do sexo masculino e aspectos socioculturais e familiares em função de histórico de sobrepeso/obesidade. Em contrapartida, esta revisão sustenta que a dieta saudável e atividade física e a redução do tempo de tela representam um fator de manutenção da saúde contra o sobrepeso/obesidade.

INTRODUCCIÓN: La malnutrición por exceso afecta aproximadamente a 337 millones de niños, niñas y adolescentes en el mundo. Entre los aspectos multifactoriales asociados a la obesidad, destaca el contexto Pandemia por COVID-19, el cual ha aumentado las cifras de obesidad infantil. Por otro lado, la obesidad es considerada un factor de riesgo para desarrollar de forma grave la enfermedad por COVID-19. Este estudio busca analizar el efecto de la pandemia en los índices de malnutrición por exceso en los niños, niñas y adolescentes atendidos en el centro médico de la carrera de medicina de la Universidad de Tarapacá durante el año 2021 y compararlos con estudios previos realizados en Chile. METODOLOGÍA: La investigación tiene un enfoque analítico, transversal, retrospectivo y observacional. El estudio se basó en la revisión de fichas clínicas de 1094 pacientes entre 2 y 17 años atendidos en el Centro Médico de la Escuela de Medicina de la Universidad de Tarapacá en la ciudad de Arica. Los datos obtenidos fueron almacenados en plantilla Excel para ser ingresados en un programa estadístico. RESULTADOS: Del total de 1094 fichas analizadas, 611 pacientes (55,8%) se encontraron en un estado nutricional concordante con malnutrición por exceso, predominando en el sexo masculino (54,7%) y a mayor edad mayor malnutrición por exceso, encontrando mayor prevalencia de obesidad y obesidad severa en los(las) adolescentes. DISCUSIÓN: La malnutrición por exceso ha adquirido las características de epidemia y es un problema frecuente de los países en vías de desarrollo, convirtiéndose en un problema de salud pública. En este estudio se demuestra un aumento en los niveles de malnutrición por exceso durante el año 2021, comparando los resultados obtenidos en relación a la realidad nacional y regional en los años 2019 y 2020.

INTRODUCTION: Malnutrition due to excess affects approximately 337 million children and adolescents in the world. Among the multifactorial aspects associated with obesity, the COVID-19 Pandemic context stands out, which has warned the figures of childhood obesity. On the other hand, obesity is considered a risk factor for severely developing COVID-19 disease. This study seeks to analyze the effect of the pandemic on the rates of malnutrition due to excess in children and adolescents treated at the medical center of the University of Tarapacá during the year 2021 and compare them with previous studies carried out in Chile. METHODOLOGY: The research has an analytical, cross-sectional, retrospective and observational approach. The study was based on the review of clinical records of 1094 patients between 2 and 17 years of age treated at the Medical Center of the School of Medicine of the University of Tarapacá in the city of Arica. The data obtained was stored in an Excel template to be entered into a statistical program. RESULTS: Of the total of 1094 records analyzed, 611 patients (55.8%) were found to be in a nutritional state consistent with malnutrition due to excess, predominating in males (54.7%) and at older ages, finding a higher prevalence of obesity and severe obesity in adolescents.

Association between rapid weight gain and overweight in children aged 0 to 5 years in Latin America / Associação entre ganho rápido de peso e excesso de peso em crianças de 0 a 5 anos de idade na América Latina

Abstract Objectives: to assess the prevalence of rapid weight gain (RWG) in children born with normal weight and its association with overweight (OW) in four Latin America countries. Methods: cross-sectional study in children aged 0 to 5 from the Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher in Brazil and the Encuesta Nacional de Demografía y Salud in Bolivia, Colombia and Peru,using a birth weight ≥2,500g. The outcome variable was OW, the exposure was RWG and breastfeeding (BF) was the adjustment variable. Prevalence, odds ratio and 95% confidence intervalwere estimated using multivariate logistic regression model. Results: there was a greater prevalence of RWG and BF at less than 6 months in Brazil, and a greater prevalence of OW in Brazil and Bolivia. The chances of OW when RWG was present and adjusted for BF were 6.1 times (CI95% = 3.8-9.7) in Brazil, 4.4 times (CI95% = 3.6-5.3) in Bolivia, 6.7 times (CI95% = 5.5-8.2) in Colombia, and 12.2 times in Peru (CI95% = 9.4-15.7) with a p < 0.001 for all countries. Conclusions: RWG in children with normal birth weight was associated with a greater chance of being OW in the four observed Latin America countries.

Conclusões: o GRP em crianças nascidas com peso normal foi associado a maior chance de EP infantil nos quatro países da América Latina.

Impacto de un programa de actividad física musicalizada sobre la aptitud física de ancianas / Impact of musicalized physical activity program on the physical fitness of elderly women

Introducción: El envejecimiento es un proceso natural consecuencia de múltiples factores moleculares y celulares que producen un deterioro de la aptitud física. Objetivo: Determinar el impacto de un programa de actividad física musicalizada en la aptitud física de ancianas colombianas. Métodos: Estudio cuasiexperimental realizado en 49 ancianas de Bucaramanga, Colombia. Se implementó un programa de actividad física musicalizada de 10 semanas. La composición corporal, la capacidad aeróbica y la fuerza de miembros inferiores se determinaron mediante el Índice de Masa Corporal, las pruebas de seis minutos de caminata, y sentarse y levantarse de una silla, respectivamente. Las variables fueron analizadas en medidas de tendencia central o frecuencias según su naturaleza. Para determinar la existencia de una diferencia estadísticamente significativa, se usaron las pruebas t-student y exacta de Fischer. El nivel de significancia fue de p≤0,05. Resultados: Luego de la implementación del programa, se evidenció una disminución de 0,71 kg/m2 en la media de IMC, un aumento de 2,14 en la media de repeticiones en la prueba de resistencia a la fuerza y un incremento de 39,89 en la media de metros alcanzados en la prueba de capacidad aeróbica. Así mismo, aumentó el número de mujeres que pasaron a la categoría funcional en los niveles de fuerza y capacidad aeróbica y el número de mujeres que alcanzaron un peso normal. Las diferencias anteriormente mencionadas fueron estadísticamente significativas. Conclusiones: El programa de actividad física musicalizada mejoró la composición corporal y aumentó los niveles de fuerza muscular y capacidad aeróbica(AU)

Introduction: Aging is a natural process resulting from multiple molecular and cellular factors producing deterioration of physical fitness. Objective: To determine the impact of a musicalized physical activity program on the physical fitness of elderly Colombian women. Methods: A quasi-experimental study carried out in 49 elderly women from Bucaramanga, Colombia. We implemented a 10-week musicalized physical activity program. Body composition, aerobic capacity, and lower limb strength were determined by Body Mass Index, six-minute walk, and chair sitting and standing tests, respectively. The variables were analyzed in measures of central tendency or frequencies according to their nature. To determine the existence of a statistically significant difference, the t-student and Fischer's exact tests were used. The level of significance was p ≤ 0.05. Results: After implementing the program, the mean BMI decreased by 0.71 kg/m2, the mean number of repetitions increased by 2.14 in the strength resistance test and the average reached meters increased by 39 .89 in the aerobic capacity test. Likewise, the number of women who moved into the functional category in strength and aerobic capacity levels and the number of women who reached a normal weight increased. The aforementioned differences were statistically significant. Conclusions: The musicalized physical activity program improved body composition and increased levels of muscle strength and aerobic capacity(AU)

Overweight/obesity in adolescents with phenylketonuria: protective and predisposing factors

Abstract Objective: To estimate the prevalence and factors associated with overweight/obesity development in adolescents with early diagnosed phenylketonuria treated exclusively by diet. Methodology: In this cross-sectional study anthropometric measurements, serum phenylalanine levels, and 10 metabolites associated with lipid and carbohydrate metabolism were analyzed in 101 adolescents aged 10-20 years. Adolescents were categorized into overweight/obesity and eutrophic/low body mass index groups. These patients were compared using Student's t-test, Pearson's chi-square test, Wald's chi-square test for multivariate analysis. Further, to verify whether the prevalence of overweight/obesity found in the study population was similar to that in the general population, the authors compared the nutritional status of 46 patients aged 13-17 years with that of healthy students of the same age from the National School Health Survey using the chi-square test for adherence. The significance threshold was p < 0.5. Results: The prevalence of overweight/obesity in adolescents was 27.7%. There was no difference in prevalence between sexes. Older age was a protective factor and Increased Homeostasis Model Assessment Insulin Resistance index and high phenylalanine and low-density lipoprotein cholesterol levels were predictive factors for overweight/obesity. The equality hypothesis was not rejected in the comparison of nutritional states of 46 patients aged 13-17 years and healthy students of the same age. Conclusion: The prevalence of overweight/obesity in phenylketonuria adolescents was similar to what is found in healthy adolescents.

Tendência temporal (2008-2018) da prevalência de excesso de peso em lactentes e pré-escolares brasileiros de baixa renda / Time-trend analysis (2008-2018) of overweight prevalence among low-income infant and preschool children

Resumo O objetivo deste estudo foi analisar a tendência temporal da prevalência de excesso de peso (EP) em crianças menores de cinco anos assistidas pelo Programa Bolsa Família (PBF) entre 2008 e 2018. O painel de dados foi baseado nos relatórios de estado nutricional do Sistema de Vigilância Alimentar e Nutricional (SISVAN) (n=30.574.118) e analisado por meio de modelos de regressão joinpoint específicos para idade (lactentes e pré-escolares) e macrorregião. Ainda, calculou-se a cobertura do SISVAN para o PBF e a representatividade nacional, segundo projeção censitária. Na década analisada, o EP em lactentes reduziu de 11,9% (11,8; 12,0 IC95%) para 8,5% (8,4; 8,6 IC95%) (-3,6%/ano [-5,1; -2,0 IC95%]); quanto aos pré-escolares, a prevalência EP aumentou em 3,1%/ano (2,0; 4,2 IC95%) até 2015, seguida por uma retração até 2018 (-6,4%/ano [-10,1; -2,6 IC95%]). Em ambos os grupos etários, a região Norte apresentou a menor prevalência em toda série histórica e a Nordeste o pior desempenho no controle do EP infantil. A cobertura do SISVAN no PBF foi elevada e a representatividade dos dados variou entre 13,9% (Sul) e 42,2% (Nordeste). Apesar da prevalência estar acima do esperado, após 2014, identificou-se redução linear no EP em lactentes e desaceleração na taxa de crescimento nos pré-escolares.

Abstract This study aimed to analyze the overweight (OW) prevalence trends from 2008 to 2018 among under-five-year-old children assisted by the conditional cash transfer program entitled Programa Bolsa Família (PBF). The panel was based on the Food and Nutritional Surveillance System (SISVAN) (n=30,574,118) nutritional status reports. Age- (infants and preschoolers) and region-specific joinpoint regression models were used to analyze OW's prevalence temporal changes. Besides, the coverage of SISVAN for PBF and national representativity were calculated according to census projection. In the decade analyzed, OW in infants decreased from 11.9% (11.8; 12.0 95%CI) to 8.5% (8.4; 8.6 95%CI) (-3.6%/year [-5.1; -2.0 95%CI]); for preschool children, the prevalence of OW increased by 3.1%/year (2.0; 4.2 95%CI) until 2015, followed by a decrease until 2018 (-6.4%/year [-10.1; -2.6 95%CI]). In both age groups, the North region had the lowest prevalence in all time-series, and the Northeast had the worst performance in managing childhood obesity. The SISVAN's coverage in the PBF was high, and the data representativity varied between 13.9% (South) and 42.2% (Northeast). Although the prevalence was higher than expected, after 2014, it was detected a linear reduction in OW in infants and a deceleration in the growth rate in preschoolers.

Undernutrition and obesity trends in Brazilian adults from 1975 to 2019 and its associated factors / Tendências de subnutrição e obesidade em adultos brasileiros entre 1975 e 2019 e fatores associados / Tendencias de desnutrición y obesidad en adultos brasileños desde 1975 a 2019 y sus factores asociados

Nutritional status has evolved in a dual trend worldwide: underweight has become a minor or local issue while overweight or obesity has risen to play a major role in the global burden of disease. In 2014, Brazil was ranked as the third country with the highest absolute number of obese men. Our aim was to estimate trends of underweight and obesity among Brazilian adults using a comprehensive set of surveys from 1974 to 2019. The data used in the study originate from subjects aged ≥ 18 in six Brazilian national surveys, presented in chronological order: Brazilian National Survey on Household Expenses (ENDEF 1974-1975); Brazilian National Survey on Health and Nutrition (PNSN 1989); Brazilian Household Budget Survey (POF 2002-2003, 2008-2009); and Brazilian National Health Survey (PNS 2013 and 2019). All six surveys were designed to sample household complexes that were representative of the Brazilian population. Body mass index was calculated (kg/m2). The nutritional status of individuals was classified following the standards. We have modeled obesity trend according to income and education strata. The trajectories of underweight and obesity over time in Brazil draw the classical "X" of nutrition transition. From 1975 to 2019 underweight has decreased from 9.1% to 2.5% among men and 12.2% to 3.4% among women. On the other hand, obesity trajectories have scaled up from 3% to 22% among men and from 9% to 30% among women. The increase in obesity rate is directly and negatively proportional to income quintiles. Sociodemographic (income and education) improvement is associated with an increase in obesity. All public policies intending to stop the obesity spread in Brazil have been ineffective or too small to be effective.

O estado nutricional tem evoluído em duas direções no mundo: o baixo peso se tornou uma questão menor ou local, enquanto o sobrepeso ou obesidade passou a ter papel preponderante na carga global de doença. Em 2014, o Brasil ocupou terceiro lugar no mundo em número absoluto de homens obesos. O estudo teve como objetivo estimar as tendências nas taxas de baixo peso e obesidade entre adultos brasileiros, tendo como base um conjunto abrangente de inquéritos entre 1974 e 2019. Os dados utilizados no estudo se referem a indivíduos com 18 anos ou mais em seis pesquisas nacionais, apresentadas em ordem cronológica: Estudo Nacional de Despesa Familiar (ENDEF 1974-1975); Pesquisa Nacional sobre Saúde e Nutrição (PNSN 1989); Pesquisa de Orçamentos Familiares (POF 2002-2003, 2008-2009) e Pesquisa Nacional de Saúde (PNS 2013 e 2019). Todos os 6 inquéritos foram desenhados para obter amostras de complexos de domicílios que fossem representativas da população brasileira. O ídice de massa corporal foi calculado (kg/m2). O estado nutricional dos indivíduos foi classificado de acordo com as normas da Organização Mundial da Saúde. Modelamos a tendência da obesidade de acordo com as faixas de renda e escolaridade. As trajetórias de baixo peso e obesidade no Brasil ao longo do tempo mostram a forma clássica em "X" da transição nutricional. Entre 1975 e 2019, a taxa de baixo peso diminuiu de 9,1% para 2,5% entre homens e de 12,2% para 3,4% entre mulheres. Inversamente, as trajetórias da obesidade aumentaram de 3% para 22% entre homens e de 9% para 30% entre mulheres. O incremento na obesidade está relacionado diretamente e de maneira negativamente proporcional aos quintis de renda. A melhoria sociodemográfica (de renda e escolaridade) está associada ao aumento da obesidade. Todas as políticas públicas para interromper a expansão da obesidade no Brasil têm sido ineficazes, ou pequenas demais para ser eficazes.

El estatus nutricional ha evolucionado en una doble tendencia alrededor del mundo: el bajo peso se ha convertido en un problema menor o local, mientras que el sobrepeso o la obesidad ha aumentado desempeñando un papel importante en la carga global de la enfermedad. En 2014, Brasil se situó como el tercer país con la mayor carga absoluta de hombres obesos. Nuestro objetivo fue estimar las tendencias de bajo peso y obesidad entre brasileños adultos, utilizando un conjunto completo de encuestas desde 1974 a 2019. Los datos usados en el estudio procedieron de individuos con ≥18 años en 6 encuestas nacionales brasileñas, presentadas en orden cronológico: Estudio Nacional sobre Gasto Familiar (ENDEF 1974-1975); Encuesta Nacional de Salud y Nutrición (PNSN 1989); Encuestas sobre Presupuesto Familiar (POF 2002-2003, 2008-2009); y Encuesta Nacional de Salud (PNS 2013 y 2019). Las 6 encuestas se diseñaron para las muestras complejas de hogares que eran representativas de la población brasileña. Se calculó el indice de masa corporal (kg/m2). El estatus nutricional de los individuos se clasificó siguiendo los estándares de la Organización Mundial de la Salud. Hemos modelado la tendencia a la obesidad según el nivel de ingresos y educación. Las trayectorias de bajo peso y obesidad a lo largo del tiempo en Brasil dibujaron la clásica "X" de transición nutricional. Desde 1975 a 2019, ha decrecido el bajo peso de 9,1% a 2,5% entre hombres y de 12,2% a 3,4% entre mujeres. Las trayectorias de obesidad, en cambio, escalan desde el 3% al 22% entre hombres, y desde el 9% al 30% entre mujeres. El incremento en la tasa de obesidad es directamente y negativamente proporcional a los quintiles de ingresos. La mejora sociodemográfica (ingresos y educación) está asociada con un incremento en la obesidad. Todas las políticas públicas puestas en práctica para intentar detener la propagación de la obesidad en Brasil han sido inefectivas o demasiado pequeñas para ser efectivas.

Methods: This was an ecological time series study using data on Brazilian macro-regions. The annual percent change in the classification of nutritional status and total coverage was estimated using the Prais-Winsten regression model. Results: A total of 115,034,534 records were identified in the period. Coverage increased from 5.0% in 2008 to 10.6% in 2019, with an annual change of 8.4%, 95% confidence interval (95%CI 6.7;10.0). Obesity and overweight showed a rising trend between 2008 and 2019, with an annual change of 6.4% (95%CI 5.3;7.3) and (1.8%; 95%CI 1.2;2.5) respectively, while underweight (-7.0%; 95%CI -8.0;-6.1) and eutrophy (-3.8%; 95%CI -4.1;-3.4) decreased in the period. Conclusion: There was an improvement in SISVAN coverage, with an increase in overweight and obesity among the population studied.

Insatisfação com a imagem corporal, uso de drogas e fatores associados entre adolescentes em três cidades brasileiras / Body dissatisfaction, drug use, and associated factors among adolescents in three Brazilian cities / Insatisfacción con la imagen corporal, uso de drogas y factores asociados entre adolescentes en tres ciudades brasileñas

Resumo Objetivo: analisar a associação entre uso de drogas e a insatisfação com a imagem corporal de adolescentes em três cidades brasileiras. Método: estudo transversal, aninhado em um ensaio controlado randomizado para avaliar o programa de prevenção ao uso de drogas em escolas brasileiras #TamoJunto2.0 do Ministério da Saúde. A amostra foi de 5.213 alunos de 73 escolas de três cidades brasileiras. O desfecho satisfação corporal foi analisado por meio da escala de Silhuetas de Stunkard e as variáveis explicativas foram o uso de drogas e dados sociodemográficos. Resultados: os adolescentes tinham entre 12 e 14 anos e cerca de 69,9% relataram insatisfação corporal, e no último ano 35,67% utilizaram álcool. A insatisfação por sobrepeso foi maior nas meninas (41,5%) e por baixo peso nos meninos (33,1%). Os adolescentes que usavam maconha apresentaram 39% (OR=1,39) mais chance de insatisfação por baixo peso e ser menina aumentou em 24% (OR=1,24) as chances de insatisfação por sobrepeso. Conclusão: os níveis de insatisfação corporal merecem atenção no cuidado de enfermagem hebiátrica e reforçam a necessidade de estratégias educativas abordando a imagem corporal e uso de drogas, a relacionando aos vários atributos subjetivos que podem afetar a saúde dos adolescentes, seja na comunidade ou escola.

Abstract Objective: analyze the association between drug use and body dissatisfaction among adolescents in three Brazilian cities. Method: cross-sectional study, using a nested randomized controlled trial to evaluate the drug use prevention program #TamoJunto2.0 of the Ministry of Health in Brazilian schools. The sample consisted of 5,213 students from 73 schools in three Brazilian cities. The outcome body satisfaction was analyzed using the Stunkard scale and the explanatory variables were drug use and sociodemographic data. Results: the adolescents were between 12 and 14 years old; about 69.9% of them reported body dissatisfaction, and 35.67% used alcohol in the previous year. Dissatisfaction due to overweight was higher among girls (41.5%) and dissatisfaction due to underweight was higher among boys (33.1%). Adolescents who used marijuana were 39% (OR=1.39) more likely to feel dissatisfied due to underweight and being a girl increased the chances of feeling dissatisfied due to overweight by 24% (OR=1.24). Conclusion: the levels of body dissatisfaction deserve attention in hebiatric nursing care and reinforce the importance of educational strategies addressing body image and drug use, relating them to the various subjective attributes that can affect the health of adolescents, whether in the community or at school.
