Association of outdoor artificial light at night exposure with overweight and obesity among children and adolescents aged 9 to 18 years in China / 北京大学学报(医学版)

OBJECTIVE@#To analyze the association between outdoor artificial light-at-night (ALAN) exposure and overweight and obesity among children and adolescents aged 9 to 18 years in China.@*METHODS@#Using follow-up data of 5 540 children and adolescents aged 9 to 18 years conducted from November 2019 to November 2020 in eight provinces of China, latitude and longitude were determined based on school addresses, and the mean monthly average nighttime irradiance at the location of 116 schools was extracted by the nearest neighbor method to obtain the mean outdoor ALAN exposure [unit: nW/(cm2·sr)] for each school. Four indicators of overweight and obesity outcomes were included: Baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence. Mixed effects Logistic regression was used to explore the association between ALAN exposure levels (divided into quintiles Q1-Q5) and baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence. In addition, a natural cubic spline function was used to explore the exposure response association between ALAN exposure (a continuous variable) and the outcomes.@*RESULTS@#The prevalence of baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence among the children and adolescents in this study were 21.6%, 16.3%, 2.9% and 12.8%, respectively. The OR value for the association between ALAN exposure and baseline overweight and obesity was statistically significant when ALAN exposure levels reached Q4 or Q5, 1.90 (95%CI: 1.26-2.86) and 1.77 (95%CI: 1.11-2.83), respectively, compared with the children and adolescents in the Q1 group of ALAN exposure. Similar to the results for baseline overweight and obesity, the OR values for the association with persistent overweight and obesity were 1.89 (95%CI: 1.20-2.99) and 1.82 (95%CI: 1.08-3.06) when ALAN exposure levels reached Q4 or Q5, respectively, but none of the OR values for the association between ALAN and overweight and obesity progression and overweight and obesity incidence were statistically significant. Fitting a natural cubic spline function showed a non-linear trend between ALAN exposure and persistent overweight and obesity.@*CONCLUSION@#There is a positive association between ALAN exposure and overweight and obesity in children and adolescents, and the promotion of overweight obesity in children and adolescents by ALAN tends to have a cumulative effect rather than an immediate effect. In the future, while focusing on the common risk factors for overweight and obesity in children and adolescents, there is a need to improve the overweight and obesity-causing nighttime light exposure environment.

Overweight and associated factors in Basic Education teachers during the Covid-19 pandemic: gender differentials / Excesso de peso e fatores associados entre professores da Educação Básica durante a pandemia de Covid-19: diferenciais de sexo

ABSTRACT Objective To estimate the prevalence of overweight among teachers in Minas Gerais during the Covid-19 pandemic and to review relevant gender associated factors. Methods Cross-sectional and analytical study, websurvey type, carried out with 15,641 teachers of public Basic Education in Minas Gerais, Brazil. Data collection took place from August to September 2020 with the use of a digital form. The dependent variable was overweight, calculated by the body mass index using the teachers' self-reported weight and height. Poisson regression was used, with robust variance. Results Among the participating teachers, 52.4% were overweight. When stratified by gender, 51.1% women and 58.2% men were considered overweight, with a significant difference between them (p<0.001). There was a higher prevalence of overweight among women in the age group of 30 to 59 years (PR=1.39) and in women 60 years or older (PR=1.45) living in the metropolitan region of the state (PR=1.06) who had children (PR=1.19), who were not exercising (PR=1.09) and with a worse dietary pattern during the pandemic (PR=1.12), much afraid of Covid-19 (PR=1.04) and with anxiety and/or depression during the pandemic (PR=1.14). Among men, there was a higher prevalence of overweight among those individuals aged 30 to 59 years (PR=1.19), who lived with a spouse (PR=1.15) working more than 40 hours per week (PR=1.12) and those with the worst dietary pattern during the pandemic (PR=1.10). Conclusion The results showed a 52.4% prevalence of overweight teachers and different associated factors between the genders.

Entre os homens, houve maior prevalência de excesso de peso entre aqueles de 30 a 59 anos (RP=1,19), que viviam com cônjuge (RP=1,15), que trabalhavam mais de 40 horas semanais (RP=1,12) e aqueles com pior padrão alimentar durante a pandemia (RP=1,10). Conclusão Os resultados evidenciaram que 52,4% dos professores respondentes estavam com excesso de peso, tendo sido encontrados diferentes fatores associados entre os sexos.

Inadequacies of gestational weight gain: prevalence and association with sociodemographic characteristics and the living environment / Inadequações do ganho de peso gestacional: prevalência e associação com características sociodemográficas e do ambiente de moradia

ABSTRACT Objective To assess the association of gestational weight gain inadequacies with sociodemographic indicators and characteristics of the living environment. Methods Cross-sectional study conducted in 2019 with a probabilistic sample of 3580 postpartum women who gave birth in maternity hospitals of the Unified Health System in the State of Santa Catarina. Prevalence was calculated and, using logistic regression models, odd ratios of inadequate and adequate gestational weight gain were estimated according to sociodemographic and health indicators (Body Mass Index, age, marital status, race/skin color and education); and characteristics of the neighborhood (violence, social cohesion, encouragement to practice physical activity and access to healthy food). Results It was observed that 29.6% of the mothers had adequate gestational weight gain, 29.3% insufficient and 41.1% excessive gestational weight gain. Lower chances of adequate weight gain were found in women with pre-pregnancy body mass index classified as overweight (43.0%) and obesity (58.0%) and who lived in an environment with social cohesion (25.0%). In contrast, the chances of adequate weight gain were 43.0% higher among women with 12 years of schooling or more when compared to those with 8 years or less. Conclusion Inadequate gestational weight gain is associated with high pre-pregnancy body mass index, with social cohesion in the living environment and with a low level of education of the pregnant woman, requiring public policies that go beyond prenatal care.

RESUMO Objetivo Analisar a associação do ganho de inadequações do peso gestacional com indicadores sociodemográficos e características do ambiente de residência. Métodos Estudo transversal realizado em 2019, com amostra probabilística de 3.580 puérperas que realizaram o parto no Sistema Único de Saúde em maternidades do Estado de Santa Catarina. Foram calculadas as prevalências e, por meio de modelos de regressão logística, foram estimadas razões de chance de ganho de peso gestacional inadequado e adequado, segundo indicadores sociodemográficos e de saúde (Índice de Massa Corporal, idade, estado civil, raça/cor da pele e escolaridade) e características da vizinhança de residência (violência, coesão social, estímulo à prática de atividade física e acesso à alimentação saudável). Resultados Observou-se que 29,6% das puérperas tiveram ganho de peso gestacional adequado, 29,3% insuficiente e 41,1% excessivo. Menores chances de ganho de peso adequado foram encontradas em mulheres com índice de massa corporal pré-gestacional de sobrepeso (43,0%) e obesidade (58,0%) e que viviam em ambiente com coesão social (25,0%). Já as chances de ganho de peso adequado foram 43,0% maiores entre as mulheres com 12 anos ou mais de estudo quando comparadas àquelas com 8 anos ou menos. Conclusão O ganho de peso gestacional inadequado está associado com o índice de massa corporal pré-gestacional elevado, com a coesão social no ambiente de moradia e com a baixa escolaridade da gestante, exigindo políticas públicas que transcendam o cuidado básico do pré-natal.

Association between breastfeeding and overweight/obesity in schoolchildren aged 7-14 years / Associação entre aleitamento materno e sobrepeso/obesidade em escolares de 7-14 anos

ABSTRACT Objective: To evaluate the prevalence of breastfeeding (BF) and the association between occurrence/duration of BF and overweight/obesity in schoolchildren aged 7-14 years. Methods: This is a cross-sectional study, conducted in 2012-2013, on schoolchildren aged 7-14 years from Florianópolis, Santa Catarina, Southern Brazil. Weight and height were measured according to procedures of the World Health Organization. Breastfeeding and sociodemographic data were obtained from a questionnaire responded by parents/guardians. BF was categorized as a dichotomous variable (yes/no) and according to duration (months). Nutritional status was evaluated according to the Z score of the body mass index per age for sex and it was categorized into two groups: normal weight (<Z score+1) and overweight/obesity (≥Z score+1). The adjusted analysis was performed by logistic regression in two age strata (age groups of 7-10 and 11-14 years). Results: 6.6% of schoolchildren had never breastfed; 16.8% had been breastfed for ≤3 months; 16.7%, for 4-6 months; and 59.9%, for ≥7 months. No statistically significant differences were found in the occurrence and duration of BF between the age groups. The prevalence of overweight/obesity was 34.2%. For age groups (7-10 and 11-14 years), the prevalence of overweight/obesity was 36.7% and 29.8%, respectively. Chance of overweight/obesity for the age group of 7-10 years was lower among schoolchildren who were breastfed (OR=0.54; 95%CI 0.33-0.88), when compared with those who never breastfed. When categorized, the chance of overweight/obesity in the age group of 7-10 years was lower for duration of BF ≤3 months (OR=0.41; 95%CI 0.20-0.83), and 4-6 months (OR=0.48; 95%CI 0.28-0.82) when compared with children who never breastfed. Conclusions: BF for at least six months was associated with a lower chance of overweight/obesity for schoolchildren aged 7-10 years. No association was found for schoolchildren aged 11-14 years.

RESUMO Objetivo: Investigar prevalência e duração de aleitamento materno (AM) e sua associação com sobrepeso/obesidade em escolares de 7-14 anos. Métodos: Estudo transversal, realizado em 2012-2013, com escolares de 7-14 anos de Florianópolis, Santa Catarina. Peso e altura foram mensurados segundo preconizado pela Organização Mundial da Saúde (OMS). Dados sociodemográficos e sobre AM foram obtidos por questionários enviados aos responsáveis/cuidadores. A variável amamentação foi analisada como dicotômica (sim/não) e por duração (em meses). O perfil antropométrico foi avaliado por escore Z do índice de massa corporal (IMC) para a idade, segundo sexo, categorizado em: normal (<escore Z+1) e sobrepreso/obesidade (≥escore Z+1). Análises ajustadas foram realizadas (regressão logística) em dois estratos etários (7-10 e 11-14 anos). Resultados: 6,6% dos escolares nunca tinham sido amamentados, 16,8% foram amamentados por ≤3 meses, 16,7% por 4-6 meses e 59,9% por ≥7 meses. Não houve diferença estatística de ocorrência/duração de AM entre os grupos etários. A prevalência de sobrepeso/obesidade foi 34,2%. Nos grupos etários (7-10 e 11-14 anos), a prevalência foi 36,7% e 29,8%, respectivamente. A chance de sobrepeso/obesidade nos escolares de 7-10 anos foi menor entre aqueles que tinham sido amamentados (OR=0,54; IC95% 0,33-0,88), comparando com os nunca amamentados. Quando categorizada, a chance de ter sobrepeso/obesidade nos escolares de 7-10 anos foi menor quando a duração do AM foi ≤3 meses (OR=0,41; IC95% 0,20-0,83) e 4-6 meses (OR=0,48; IC95% 0,28-0,82), em comparação à ausência de AM. Conclusões: AM por pelo menos seis meses foi associado com menor chance de sobrepeso/obesidade para escolares de 7-10 anos. Não foi observada associação para o grupo 11-14 anos.

Objective@#Nutrition is closely related to the health of the elderly population. This study aimed to provide a comprehensive picture of the nutrition status of elderly Chinese and its related dietary, geographical, and socioeconomic factors.@*Methods@#A total of 13,987 ≥ 60-year-old persons from the 2010-2013 Chinese National Nutrition and Health Survey were included to evaluate various aspects of malnutrition, including underweight, overweight or obesity, and micronutrient inadequacy.@*Results@#Overall, the prevalence of obesity, overweight, and underweight was 12.4%, 34.8%, and 5.7%, respectively, with disparities both geographically and socioeconomically. The prevalence of underweight was higher among the older old (≥ 75 years), rural residents and those with low income, with low education status, and residing in undeveloped West areas. More than 75% of the elderly do not meet the Dietary Reference Intakes for vitamins A, B @*Conclusions@#Obesity epidemic, inadequacy of micronutrient intake, and high prevalence of underweight and anemia in susceptible older people are the major nutrition challenges for the rapidly aging population in China.

The role of health-related behaviors in gestational weight gain among women with overweight and obesity: A cross-sectional analysis / Papel dos comportamentos relacionados à saúde no ganho de peso gestacional em mulheres com sobrepeso e obesidade: Um estudo transversal

Abstract Objective To evaluate the influence of health-related behaviors including food intake, physical activity, sleep time, smoking habits, stress, depression, and optimism on excessive gestational weight gain (GWG) among women with overweight and obesity. Methods A cross-sectional study was conducted at the Women's Hospital of the Universidade de Campinas, Campinas, state of São Paulo, Brazil, with 386 mediate postpartum women that fit the inclusion criteria of ≥ 19 years old, first prenatal care visit at or before 14 weeks, and single live baby. Dietary habits, physical exercise practice, sleep duration, smoking and alcohol habits were self-reported. Psychosocial history was evaluated using the Edinburgh Postpartum Depression Scale (EPDS), Perceived Stress Scale (PSS), and Life Orientation Test-Revised (LOT-R). Sociodemographic, obstetric, anthropometric, and neonatal data were retrieved from medical records. Descriptive statistics and stepwise logistic regression were performed. Results The prevalence of overweight and obesity was 29.27% and 24.61%, respectively, according to the body mass index (BMI). Excessive GWG was observed in 47.79% of women with overweight and in 45.26% of women with obesity. Excessive GWG among overweight and obese women was associated with inadequate vegetable and bean consumption (odds ratio [OR] = 2.95, 95% confidence interval [CI]: 1.35-6.46 and OR = 1.91; 95%CI: 1.01-3.63, respectively) and stress (OR = 1.63; 95%CI 1.01-2.64). After adjustment by maternal age, multiparity, sleep duration, smoking, and alcohol intake, we found that stress (PSS ≥ 20) was associated with excessive GWG in women with overweight or obesity (OR: 1.75; 95%CI: 1.03-2.96). Conclusion Among women with overweight and obesity, stress is the main variable associated with excessive GWG. Inadequate vegetables and beans consumption also showed association with excessive GWG.

Resumo Objetivo Avaliar a influência de comportamentos relacionados à saúde: ingestão alimentar, atividade física, tempo de sono, tabagismo, estresse, depressão e otimismo no ganho de peso gestacional (GPG) excessivo em mulheres com sobrepeso e obesidade. Métodos Estudo transversal no Hospital da Mulher, Universidade de Campinas, Campinas, SP, Brasil, com 386 mulheres no puerpério mediato, ≥ 19 anos, primeira consulta pré-natal até 14 semanas e cuja gestação resultou em neonato vivo. Os comportamentos relacionados à saúde foram autorreferidos. História psicossocial foi avaliada usando: Escala de Depressão Pós-Parto de Edimburgo (EPDS, na sigla em inglês), Escala de Estresse Percebido (PSS, na sigla em inglês) e Teste de Orientação à Vida-Revisado (LOT-R, na sigla em inglês). Dados sociodemográficos, obstétricos, antropométricos e neonatais foram obtidos dos prontuários médicos. Realizou-se análises descritivas e regressão logística. Resultados A prevalência de sobrepeso e obesidade foi de 29,27% e de 24,61%, respectivamente. Ganho de peso gestacional excessivo foi observado em 47,79% das mulheres com sobrepeso e em 45,26% das mulheres com obesidade. O consumo inadequado de verduras e feijão (razão de probabilidade [OR] = 2,95; índice de confiança [IC] 95%: 1,35-6,46 e OR = 1,91; IC95%: 1,01-3,63, respectivamente) e estresse (OR = 1,63; IC95%: 1,01-2,64) foram associados ao GPG excessivo em mulheres com sobrepeso e obesidade. Análises ajustadas para idade materna, multiparidade, duração do sono, tabagismo e ingestão de álcool mostraram que o estresse (PSS ≥ 20) associou-se ao GPG excessivo em mulheres com sobrepeso e obesidade (OR = 1.75; 95%CI: 1.03-2.96). Conclusão Entre mulheres com sobrepeso e obesidade, o estresse foi a principal variável associada ao GPG excessivo. O consumo inadequado de verduras e feijão também se associou com o GPG excessivo.

Overweight and associated factors in children and adolescents with phenylketonuria: a systematic review / Excesso de peso e fatores associados em crianças e adolescentes com fenilcetonúria: uma revisão sistemática

ABSTRACT Objective: To verify the occurrence of overweight in children and adolescents with phenylketonuria and to identify possible causal factors. Data sources: A systematic review was performed in the SciELO, PubMed and VHL databases using the descriptors "Phenylketonurias", "Overweight", "Child" and "Adolescent". Original articles conducted with children and adolescents, published between 2008 and 2018 in Portuguese, English or Spanish languages were included. Data synthesis: A total of 16 articles were identified and, after screening procedures, 6 studies were selected for the review. Overweight in children and adolescents with phenylketonuria was a frequent occurence in the studies included in this review, ranging from 7.8 to 32.6%. The female sex was the most affected by the nutritional disorder. Furthermore, a high caloric intake combined with a lack of stimuli to practice physical activities were main factors associated with the excessive weight in the population of interest. Conclusions: Excess weight can be considered a common outcome in children and adolescents with phenylketonuria. It is mainly caused by inadequate food consumption and sedentary lifestyle. The importance of early identification of nutritional disturbances in children and adolescents with phenylketonuria should be emphasized, in order to prevent associated chronic diseases and to promote health by encouraging continued healthy eating habits and the regular practice of physical exercises.

RESUMO Objetivo: Verificar a ocorrência de excesso de peso em crianças e adolescentes com fenilcetonúria e identificar possíveis fatores causais. Fontes de dados: Revisão sistemática realizada nas bases de dados Scientific Eletronic Library Online (SciELO), Publisher Medline (PubMed) e Biblioteca Virtual em Saúde (BVS) com os descritores "Phenylketonurias", "Overweight", "Child" e "Adolescent". Foram incluídos artigos originais sobre crianças e adolescentes, publicados entre 2008 e 2018 nos idiomas português, inglês ou espanhol. Síntese dos dados: Foram identificados 16 artigos e, após aplicação dos procedimentos de seleção, 6 estudos foram selecionados para compor a revisão. O excesso de peso em crianças e adolescentes com fenilcetonúria foi evento frequente nos estudos incluídos na presente revisão, variando de 7,8 a 32,6%. Aponta-se o sexo feminino como o grupo mais acometido pelo distúrbio nutricional. O principal fator associado ao excesso de peso na população de interesse na população de interesse foi o consumo calórico elevado aliado à falta de estímulos para a prática de atividades físicas. Conclusões: O excesso de peso pode ser considerado um desfecho comum em crianças e adolescentes com fenilcetonúria, sendo ocasionado principalmente pelo consumo alimentar inadequado e pelo sedentarismo. Salienta-se a importância da identificação precoce de agravos nutricionais em crianças e adolescentes fenilcetonúricos, a fim de prevenir doenças crônicas associadas e promover a saúde, com incentivo à manutenção de hábitos alimentares saudáveis e à prática regular de exercícios físicos.

Efectos endocrinológicos tardíos del tratamiento oncológico en supervivientes de meduloblastoma / Endocrinological late effects of oncologic treatment on survivors of medulloblastoma

INTRODUCCIÓN: La radioterapia, quimioterapia y la cirugía empleada en el tratamiento de los tumores cerebrales tienen efectos en el eje hipotálamo-hipofisario y pueden resultar en disfunción endocrina hasta en el 96% de los casos. PACIENTES Y MÉTODO: Estudio retrospectivo y descriptivo en pacientes diagnos ticados de meduloblastoma sometidos a tratamiento con quimio y radioterapia en los últimos 20 años en un hospital terciario. Se analizan variables edad, sexo, peso, talla, índice de masa corporal (IMC) al final del seguimiento, estadio de maduración sexual, niveles séricos de TSH y T4 libre, ACTH/cortisol e IGF-1, FSH, LH, estradiol, testosterona, perfil lipídico (colesterol total) y prueba de función dinámica de hormona de crecimiento. RESULTADOS: Muestra total de 23 pacientes. El déficit de hormona de crecimiento es la secuela más frecuente (82 %) seguido de disfunción ti roidea (44,8%) y disfunción puberal (24,1%). Solo se diagnosticó un caso de diabetes insípida y 2 casos de déficit de corticotrofina. CONCLUSIONES: El seguimiento a largo plazo de los supervivientes de meduloblastoma tratados con quimio y radioterapia revela una prevalencia muy alta de disfun ción endocrina, particularmente de deficiencia de hormona del crecimiento y de hipotiroidismo. Creemos oportuna la monitorización y el seguimiento a largo plazo de estos pacientes con el fin de garantizar un manejo terapéutico adecuado de aquellas disfunciones tratables.

INTRODUCTION: Radiation therapy, chemotherapy, and surgery used to treat brain tumors have effects on the hy pothalamic-pituitary-adrenal axis and can result in endocrine dysfunction in up to 96% of cases. PATIENTS Y METHOD: Retrospective and descriptive study in patients diagnosed with medulloblasto ma who underwent treatment with chemo and radiotherapy in the last 20 years in a tertiary hospital. The variables analyzed were age, sex, weight, height, body mass index (BMI) at the end of follow-up, sexual maturity stage, serum levels of TSH and free T4, ACTH/cortisol and IGF-1, FSH, LH, estradiol, testosterone, lipid profile (total cholesterol), and growth hormone dynamic function test. RESULTS: Total sample of 23 patients. Growth hormone deficiency is the most frequent sequelae (82%) fo llowed by thyroid dysfunction (44.8%), and disorders of puberty (24.1%). Only one case of diabetes insipidus and two cases of corticotropin deficiency were diagnosed. CONCLUSIONS: Long-term follow- up of medulloblastoma survivors treated with chemo and radiotherapy reveals a very high prevalence of endocrine dysfunction, especially growth hormone deficiency and hypothyroidism. We believe that monitoring and long-term follow-up of these patients is necessary in order to ensure adequate therapeutic management of those treatable dysfunctions.

Growth and weight status of Brazilian children with autism spectrum disorders: A mixed longitudinal study / Crescimento e massa corporal em crianças brasileiras com transtornos do espectro autista: um estudo longitudinal misto

ABSTRACT Objective: This study examined the growth status and physical development of Brazilian children with autism spectrum disorders from 4 to 15 years of age. Furthermore, it was examined whether variation in growth patterns and weight status was influenced by the use of psychotropic medications. Methods: One-hundred and twenty children aged 3.6-12.1 years at baseline (average = 7.2 years, SD = 2.3 years) diagnosed with autism spectrum disorders were measured on three repeated occasions across a 4-year period. Stature, body mass, and body mass index were considered. Bayesian multilevel modeling was used to describe the individual growth patterns. Results: Growth in stature was comparable to the age-specific 50th percentile for Centers for Disease Control and Prevention reference data until approximately 8 years, but a substantial decrease in growth rate was observed thereafter, reaching the age-specific 5th percentile at 15 years of age. Both body mass and body mass index values were, on average, higher than both the Brazilian and Centers for Disease Control and Prevention age-specific 95th percentile reference until 8 years, but below the 50th specific-age percentile at the age of 15 years. Conclusions: Brazilian boys with autism spectrum disorders between 4 and 15 years appear to have impaired growth in stature after 8-9 years of age, likely impacting pubertal growth. A high prevalence of overweight and obesity was observed in early childhood, although a trend of substantial decrease in body mass and body mass index was apparent when children with autism spectrum disorders entered the years of pubertal development.

RESUMO Objetivo: Este estudo examinou o estado de crescimento e o desenvolvimento físico de crianças brasileiras com transtornos do espectro autista entre 4 e 15 anos. Adicionalmente, examinamos se a variação nos padrões de crescimento e na massa corporal foi influenciada pelo uso de medicamentos psicotrópicos. Métodos: 120 crianças com idades entre 3,6 e 12,1 anos no início do estudo (média = 7,2 anos, DP = 2,3 anos) diagnosticadas com transtornos do espectro autista foram avaliadas em três ocasiões repetidas em um período de 4 anos. Foram considerados estatura, massa corporal e índice de massa corporal. O modelo multinível bayesiano foi utilizado para descrever os padrões de crescimento individual. Resultados: O crescimento em estatura foi comparável ao percentil 50 específico para a idade para os dados de referência do Centro de Controle e Prevenção de Doenças dos Estados Unidos até cerca de 8 anos. Porém, foi observada uma redução substancial na taxa de crescimento depois dos 8 anos, atingindo o percentil 5 específico para a idade aos 15 anos de idade. Tanto os valores de massa corporal quanto de índice de massa corporal foram, em média, maiores comparativamente ao percentil 95 específico para a idade até aos 8 anos da referência brasileira e do Centro de Controle e Prevenção de Doenças dos Estados Unidos, porém abaixo do percentil 50 específico para a idade aos 15 anos de idade. Conclusões: Os meninos brasileiros com transtornos do espectro autista entre 4 e 15 anos parecem ter retardo do crescimento na estatura após os 8-9 anos, provavelmente afeta o crescimento púbere. Foi observada uma alta prevalência de sobrepeso e obesidade na primeira infância, apesar de uma tendência de redução substancial na massa corporal e no índice de massa corporal ter sido aparente quando as crianças com transtornos do espectro autista entraram nos anos de desenvolvimento púbere.

Fatores clínico-comportamentais associados ao excesso ponderal em adultos jovens estudantes / Clinical-behavioral factors associated with overweight in young adults students / Factores clínico-conductuales asociados al exceso ponderal en adultos jóvenes estudiantes

Objetivo: identificar os fatores clínico-comportamentais associados ao excesso ponderal (EP) em adultos jovens estudantes. Método: estudo transversal, realizado com 560 adultos jovens de 26 escolas de uma capital do nordeste brasileiro. Após obtenção dos dados pela aplicação de questionários específicos, utilizou-se a regressão logística múltipla para identificação dos fatores associados ao EP. Resultados: o EP acometeu mais de um terço dos adultos jovens e, na análise bivariada, apresentou associação estatística significativa com as variáveis: peso na infância, peso na adolescência, história familiar de excesso ponderal, uso de fármacos obesogênicos e exposição ao álcool. No modelo final da regressão, permaneceram as variáveis: peso na adolescência, história familiar de EP e exposição ao álcool. Conclusão: a frequência de casos de EP é alta e o histórico de ganho de peso na adolescência, o histórico familiar de EP e a exposição ao álcool explicam o agravo em questão, ratificando a relação do EP com fatores genéticos e comportamentais

Objective: to identify clinical-behavioral factors associated with overweight in young adult students. Methods: a cross-sectional study was conducted with 560 young adults from 26 schools in a state capital in northeast Brazil. After obtaining the data by applying specific questionnaires, multiple logistic regression was used to identify the factors associated with overweight. Results: overweight affected more than a third of the young adult students and, in bivariate analysis, showed statistically significant associations with the variables: weight in childhood, weight in adolescence, family history of overweight, use of obesogenic drugs and exposure to alcohol. The variables retained in the final regression model were: weight in adolescence, family history of overweight and alcohol exposure. Conclusion: frequency of overweight was high, and a history of weight gain in adolescence, family history of overweight and exposure to alcohol explained the problem in question, confirming the relationship of overweight with genetic and behavioral factors.

Método: estudio transversal, realizado junto a 560 adultos jóvenes de 26 escuelas de una capital del nordeste brasileño. Después de obtener los datos por la aplicación de cuestionarios específicos, se utilizó la regresión logística múltiple para identificación de los factores asociados al EP. Resultados: el EP afecta a más de un tercio de los adultos jóvenes y, en el análisis bivariado, presentó asociación estadística significativa con las variables: peso en la infancia, peso en la adolescencia, historia familiar de exceso ponderal, uso de fármacos obesogénicos y exposición al alcohol. En el modelo final de la regresión, permanecieron las variables: peso en la adolescencia y exposición al alcohol. Conclusión: la frecuencia de casos de EP es alta y la historia de aumento de peso en la adolescencia, el historial familiar de EP y la exposición al alcohol explican el agravio en cuestión, ratificando la relación del EP con factores genéticos y conductuales.

Caracterización del consumo de alimentos e ingesta de nutrientes de población residente en las Islas Galápagos / Characterization of food consumption and nutrient intake of population resident in the Galapagos Islands

Las Islas Galápagos es una de las provincias de Ecuador con mayores índices de sobrepeso y obesidad en población adulta. Debido a las restricciones de producción de alimentos, la presión turística y otros factores sociales; la disponibilidad, el acceso y consumo de alimentos saludables y recomendables puede estar afectando al estado de seguridad alimentaria y nutricional de su población. Por ello, el objetivo de este estudio es analizar el consumo de alimentos de la población y su adecuación a las necesidades nutricionales. Sobre una muestra de 120 personas residentes en las Islas Galápagos se aplicaron 3 R24h. Los resultados de la valoración nutricional fueron comparados con las IDR, realizando un análisis factorial multivariante para analizar diferencias por grupo de edad o desempeño profesional. Se realizó un análisis de componentes principales para caracterizar el perfil de ingesta de nutrientes. Para energía y principios inmediatos se sobrepasan las recomendaciones, principalmente entre las mujeres, a la vez que se evidencia una ingesta inadecuada de fibra, iodo, ácido fólico y vitamina E. Respecto a los grupos de alimentos, el consumo medio de frutas y verduras frescas es muy escaso y el aporte proteico proviene en mayor medida de productos cárnicos (46%), seguido de pescado (24%) y arroz (17%). Los resultados de este estudio evidencian la necesidad de asegurar el acceso a alimentos frescos y saludables, en especial frutas y verduras, y promover la adopción de pautas nutricionales que promuevan un consumo adecuado de ciertos alimentos(AU)

The Galapagos Islands are one of the provinces of Ecuador with the highest rates of overweight and obesity among the adult population. Due to its restrictions on local production, tourist pressure and other social factors; availability, access and consumption to food is a problem that is related to the state of food and nutritional security of its population. Therefore, the objective of this study is to analyze the pattern of food consumption of healthy and recommended foods may be affecting the food insecurity or nutritional status of its population. Therefore, the objective of this study is to analyze the food consumption of the population and its adaptation to nutritional needs. On a sample of 120 people resident in the Galapagos Islands, 3 R24h were applied. The results of the nutritional assessment were compared with the RDI. A multivariate factor analysis has been performed to analyze differences by age group or professional performance. Principal component analysis (PCA) was performed to characterize the nutrient intake. Recommendations are exceeded for energy and immediate principles, mainly among women. On the other hand, there is an inadequate intake of fiber, iodine, folic acid and vitamin E. Regarding food groups, the average consumption of fresh fruits and vegetables is very low and protein intake comes mostly from meat products (46%), followed by fish (24%) and rice (17%). The results of this study demonstrate the need to ensure access to fresh and healthy foods, especially fruits and vegetables, and to promote the adoption of nutritional guidelines that promote adequate food intake(AU)

Metabolic and hormonal assessment of adolescent and young adult women with prior premature adrenarche

OBJECTIVE: Follow-up studies of girls with premature adrenarche have reported the development of polycystic ovary syndrome, insulin resistance, and dyslipidemia and a propensity to cardiovascular disease. The aim of this study was to analyze the presence of these conditions in patients previously treated at the Universidade Federal do Triângulo Mineiro. METHODS: A total of 130 medical records reported premature adrenarche. One hundred and twenty-two patients were invited to participate, of whom 54 accepted; 34 patients were selected, as they had reached their final height. Anthropometric, blood glucose, insulin, and lipid and hormonal profile (LH, FSH, estradiol, 17α-OH-progesterone, androstenedione, dehydroepiandrosterone sulfate, testosterone) data were obtained, the HOMA-IR index was calculated, and pelvic ultrasonography was performed. To characterize polycystic ovary syndrome and metabolic syndrome, the Rotterdam and International Diabetes Federation criteria, respectively, were used. Data were analyzed according to measures of dispersion, frequency and correlations of interest. RESULTS: The age of the participants ranged from 15.2 to 28.2 years/months; 23.5% of the patients were overweight, 11.8% were obese, 29.4% had a large waist circumference, and 8.8% were hypertensive. None of the patients had altered glucose levels, and insulin levels and HOMA-IR were elevated in 29.4% and 38.2% of the participants, respectively; 14.7% of the patients exhibited acanthosis nigricans. The lipid profiles of the participants were variable, and one patient (2.9%) had metabolic syndrome. Polycystic ovary syndrome was found in 41.2% of patients. CONCLUSION: The percentage of patients with polycystic ovary syndrome who also had overweight, obesity and insulin resistance corroborates the literature data about the need for follow-up aiming at interventions, especially for conditions associated with cardiometabolic risk.

Relationship between minimally and ultra-processed food intake during pregnancy with obesity and gestational diabetes mellitus / A relação entre consumo de alimentos minimamente processados e ultraprocessados durante a gestação e obesidade e diabetes mellitus gestacional / La relación entre el consumo de comida mínimamente procesada y ultraprocesada durante embarazos con obesidad y diabetes mellitus gestacional

This study aimed to investigate the relationship between food intake (considering the nature, extent, and purpose of food processing) during pregnancy and overweight, obesity, and gestational diabetes mellitus conditions. This is a cross-sectional study conducted among 785 adult women in singleton pregnancies (between 24th and 39th weeks of gestation) in Brazil. Usual food intake was estimated by the Multiple Source Method, using two 24-hour dietary recalls. The food groups of interest in this study were the unprocessed or minimally processed foods and ultra-processed foods. The World Health Organization criteria for the diagnosis of gestational diabetes mellitus and the Atalah criteria for excess weight were used. Adjusted multinomial logistic regression models were used to assess the relationship between energy contribution (%E) from foods with overweight and obesity conditions and, adjusted logistic regression models for gestational diabetes mellitus. In total, 32.1% participants were overweight, 24.6% were obese, and 17.7% of women were diagnosed with gestational diabetes mellitus . After adjustments, an inverse association between the highest tertile of %E from the intake of unprocessed or minimally processed foods and obesity was found [0.49 (0.30-0.79)]. Moreover, a positive association between the highest tertile of %E from ultra-processed food intake [3.06 (1.27-3.37)] and obesity was observed. No association between food intake (considering the nature, extent, and purpose of food processing) during pregnancy and overweight or gestational diabetes mellitus was found. The findings suggest a role of food processing in obesity but not in gestational diabetes mellitus. Further research is warranted to provide robust evidence on the relationship between the role of processed foods in obesity and gestational diabetes mellitus.

O objetivo deste estudo foi investigar a relação entre o consumo de alimentos (considerando a natureza, extensão e propósito do processamento de alimentos) durante a gestação e sobrepeso, obesidade e diabetes mellitus gestacional. Estudo transversal realizado com 785 mulheres adultas com gestações únicas (24ª-39ª semanas de gestação) no Brasil. O consumo usual de alimentos foi estimado usando o Multiple Source Method, usando recordatórios alimentares de 24 horas. Os grupos alimentares de interesse neste estudo foram os alimentos não-processados e minimamente processados e os alimentos ultraprocessados. Os critérios da Organização Mundial da Saúde para diagnóstico de diabetes mellitus gestacional e critérios de Atalah para excesso de peso foram usados. Modelos de regressão logística multinomial foram empregados para avaliar a relação entre a contribuição energética (%E) de alimentos e sobrepeso e obesidade, e modelos de regressão logística ajustados foram usados para diabetes mellitus gestacional. No total, 32,1% das gestantes estavam com sobrepeso, 24,6% com obesidade e 17,7% foram diagnosticadas com diabetes mellitus gestacional. Após ajustes, uma associação inversa entre obesidade e o maior tercil de %E do consumo de alimentos não-processados ou minimamente processados foi encontrada [0,49 (0,30-0,79)]. Além disso, uma associação positiva entre obesidade e o maior tercil de %E do consumo de alimentos ultraprocessados [3,06 (1,27-3,37)] foi observada. Nenhuma associação entre consumo de alimentos (considerando a natureza, extensão e propósito do processamento de alimentos) durante a gestação e sobrepeso ou diabetes mellitus gestacional foi encontrada. Os resultados sugerem o papel do processamento de alimentos na obesidade, mas não na diabetes mellitus gestacional. Pesquisas adicionais são necessárias para fornecer evidências robustas sobre a relação entre o papel do processamento de alimentos na obesidade e na diabetes mellitus gestacional durante a gestação.

El objetivo del presente estudio fue investigar la relación entre el consumo de comida (considerando la naturaleza, alcance, y propósito del procesamiento de comida) durante el embarazo y el sobrepeso, obesidad, y diabetes mellitus gestacional. Se realizó un estudio transversal con 785 mujeres adultas de embarazos únicos (24ª-39ª semanas de gestación) en Brasil. El consumo habitual se estimó mediante un Multiple Source Method, usando dos encuestas de 24-hour en relación con los hábitos alimentarios. Los grupos de comidas de interés en el presente estudio fueron los mínimamente procesados o sin procesar y los productos de comida ultraprocesada. Se utilizaron criterios de la Organización Mundial de la Salud para el diagnostico de diabetes mellitus gestacional, y los criterios Atalah para el sobrepeso. Se utilizaron modelos ajustados de regresión logística multinomial para evaluar la relación entre la contribución energética (%E) de comidas con el sobrepeso y la obesidad, y modelos ajustados de regresión logística para la diabetes mellitus gestacional . En total, un 32,1% sufrían sobrepeso, un 24,6% eran obesas, y un 17,7% de las mujeres fueron diagnosticadas con diabetes mellitus gestacional. Tras los ajustes, se encontró una asociación inversa entre el tercil más alto de %E, procedente del consumo de comidas sin procesar o mínimamente procesadas con la obesidad [0,49 (0,30-0,79)]. Asimismo, se encontró una asociación positiva entre el tercil más alto de %E de comida ultraprocesada [3,06 (1,27-3,37)] y la obesidad. No se encontró ninguna asociación entre el consumo de comida (considerando la naturaleza, alcance, y propósito de la comida procesada) durante el embarazo y el sobrepeso, respecto a la diabetes mellitus gestacional. Los resultados sugieren la importancia de la comida procesada en la obesidad pero no así en la diabetes mellitus gestacional. Son necesarias más investigaciones para proporcionar evidencias sólidas sobre la relación entre el papel de la comida procesada en la obesidad y diabetes mellitus gestacional durante el embarazo.

Experiencia de caries dental y masa corporal en escolares peruanos / Dental caries and body mass among Peruvian schoolchildren

Introducción: comprender el impacto de los desórdenes metabólicos en la salud se ha vuelto una problemática mundial en los últimos años. Objetivo: determinar la relación entre el índice de masa corporal con la prevalencia de caries dental en escolares peruanos. Métodos: el diseño fue de tipo descriptivo, transversal y correlacional. Se estudiaron 220 escolares de 6 a 12 años de edad de Huando-Huancavélica, en el año 2016. La selección de la muestra fue aleatoria, en la que se cumplieron los criterios de inclusión y exclusión, y se siguieron las normas éticas en investigación. Los datos se analizaron en el programa SPSS 21 mediante tablas de distribución de frecuencias y la prueba chi cuadrado. Resultados: la prevalencia de caries dental fue de 91,82 por ciento (CPO-D= 4,08, ceo-d= 5,81). Con respecto al estado nutricional 30 niños presentaron desnutrición (13,63 por ciento) y 23 sobrepeso (10,45); el resto presentó un peso y talla adecuado para su edad y ninguno presentó la condición de obesidad. No hubo asociación estadística entre el IMC y caries dental (p= 0,612). Conclusiones: la malnutrición no predispone a la presencia de lesiones cariosas por su causa multifactorial, aunque se debe remarcar que ambos son problemas prioritarios en salud pública por lo cual se requiere un trabajo en conjunto entre los padres y autoridades educativas(AU)

Introduction: understanding the impact of metabolic disorders on health has become a global challenge in recent years. Objective: determine the relationship between body mass index and the prevalence of dental caries among Peruvian schoolchildren. Methods: adescriptive cross-sectional correlational study was conducted of 220 schoolchildren aged 6-12 years from Huando, Huancavelica, in the year 2016. The sample was randomly selected and met the inclusion and exclusion criteria. Ethical research standards were observed. Data were processed with the statistical software SPSS 21, using frequency distribution tables and the chi-squared test. Results: prevalence of dental caries was 91.82 percent (CPO-D= 4.08, ceo-d= 5.81). Regarding the nutritional status, 30 children were malnourished (13.63 percent) and 23 were overweight (10.45 percent). The rest had a weight and height appropriate for their age, and none were obese. No statistical association was found between BMI and dental caries (p= 0.612). Conclusions: malnutrition does not predispose to the presence of carious lesions due to their multifactorial etiology, but it must be remarked that both are priority public health problems requiring the joint effort of parents and educational authorities(AU)

Treatment with Ilex paraguariensis (yerba mate) aqueous solution prevents hepatic redox imbalance, elevated triglycerides, and microsteatosis in overweight adult rats that were precociously weaned

Early weaning (EW) leads to overweight, visceral obesity, hyperleptinemia, and insulin resistance in adulthood. Treatment with Ilex paraguariensis (yerba mate) improves obesity and insulin resistance in these animals. Here, we evaluated the effects of chronic treatment with yerba mate on the redox balance and liver morphology of overweight early-weaned rats. To induce EW, we wrapped the dams with bandages to interrupt milk access during the last 3 days of lactation. Control pups (C) had free access to maternal milk for the full 21 days of lactation. On postnatal day (PN) 150, EW offspring were subdivided into the EW+YM group, which received the aqueous extract of yerba mate (1 g/kg bw by gavage once a day for 30 days) and the EW group, which received water by gavage for the same period. All rats were euthanized on PN180. The EW group showed higher bound carbonyl (a marker of total protein oxidation), higher TBARS levels (a marker of lipid peroxidation), and lower superoxide dismutase (SOD) activity in liver tissue than the C group, as well as higher triglyceride content and microsteatosis. In plasma, the EW offspring showed higher TBARS levels. One month of yerba mate treatment normalized these parameters. Thus, we have shown evidence that yerba mate improved antioxidant defenses and mitigated liver dysfunction in overweight adult rats that were weaned prematurely.

Comparação do estado nutricional e da ingestão alimentar referida por idosos de diferentes coortes de nascimento (1936 a 1940 e 1946 a 1950): Estudo Saúde, Bem-Estar e Envelhecimento (SABE) / Comparison of nutritional status and dietary intake self-reported by elderly people of different birth cohorts (1936 to 1940 and 1946 to 1950): Health, Wellbeing and Aging (SABE) Study

RESUMO: Introdução: O processo de envelhecimento é caracterizado por várias alterações, incluindo do estado nutricional e da ingestão alimentar. Para compreender a tendência dessas alterações são necessários estudos com idosos de diferentes épocas de nascimento. Objetivo: Comparar o estado nutricional e a ingestão alimentar de idosos participantes do Estudo Saúde, Bem-Estar e Envelhecimento (SABE), realizado em São Paulo, em 2000 e 2010. Métodos: O estado nutricional foi identificado pelo índice de massa corporal (IMC), considerando: baixo peso (IMC < 23 kg/m²); peso adequado (23 ≤ IMC < 28 kg/m²); excesso de peso (IMC ≥ 28 kg/m²); e a ingestão alimentar referida: número de refeições (≥ 3/dia), frequência de laticínios (≥ 1 porção/dia), de ovos e leguminosas (≥ 1 porção/semana), de frutas, legumes e verduras (≥ 2 porções/dia), de carnes (≥ 3 porções/semana) e de líquidos (≥ 5 copos/dia). A comparação foi realizada por razão de prevalência, utilizando regressão de Poisson. Resultados: Participaram 755 indivíduos de ambos os sexos, de 60 a 64 anos, nascidos nos períodos de 1936 a 1940 e 1946 a 1950. Os idosos nascidos entre 1946 e 1950 apresentaram maior razão de prevalência para excesso de peso (RP = 1,19) e para número de refeições (RP = 1,34) e para líquidos (RP = 1,18), contudo menor razão de prevalência para laticínios (RP = 0,87), para carnes (RP = 0,93) e para frutas, legumes e verduras (RP = 0,83). Conclusão: Estes resultados mostram cenários alimentar e nutricional preocupantes para a coorte mais recente (1946 - 1950).

ABSTRACT: Introduction: The aging process is characterized by several changes in individuals' life, including his or her nutritional status and food intake. To understand the trends of these changes, studies with elderly people who were born at different times are necessary. Objective: To compare the nutritional status and food intake of elderly people who participated in the Health, Well-being, and Aging study (SABE study), conducted in São Paulo, in 2000 and 2010. Methods: The nutritional status was identified by means of the body mass index (BMI) and was classified as underweight (BMI < 23 kg/m²), adequate weight (23 ≤ BMI < 28 kg/m²), or overweight (BMI ≥ 28 kg/m). Food intake was self-reported and was classified as the number of meals (≥ 3/day), frequency of intake of dairy products (≥ 1 serving/day), eggs and beans (≥ 1 serving/week), fruits and vegetables (≥ 2 servings/day), meat (≥ 3 servings/week), and liquids (≥ 5 glasses/day). The prevalence ratio was calculated to compare the variables of the cohorts, using Poisson regression. Results: A total of 755 individuals of both the genders aged 60 to 64 years and who were born between 1936 and 1940 and between 1946 and 1950 participated in this study. Elderly people who were born between 1946 and 1950 presented higher prevalence ratio of overweight (PR = 1.19), number of meals (PR = 1.34), and liquids intake (PR = 1.18), but presented lower prevalence of intake of dairy products (PR = 0.87), meats (PR = 0.93), and fruits and vegetables (PR = 0.83). Conclusion: These results showed concerning scenarios of nutritional status and food intake for the most recent cohort (1946 - 1950).

Prevalence of overweight and obesity and associated factors in school children and adolescents in a medium-sized Brazilian city

OBJECTIVES: The objective of this study was to describe the prevalence of overweight and obesity in school children and adolescents in a medium-sized Brazilian city. METHODS: In total, 1,125 children and adolescents between the ages of 5.6 and 18 years from public and private schools participated in the study. The sample included 681 girls and 444 boys. Each subject's weight and height were obtained according to Brazilian guidelines (SISVAN). The triceps (TSF), subscapular (SSF), biceps, suprailiac, femoral and calf skinfolds were measured in triplicate. Body mass index (BMI) was classified as the BMI percentile (BMIP) according to the World Health Organization (WHO) 2007 criteria. The percentage body fat (%BF) was obtained using the equations by Slaughter et al., 1998. Categorical variables were analyzed using the chi-squared test. RESULTS: Overall, 364 participants with excess weight were identified: 17.3% were overweight, and 15.0% were obese. Among the girls, 18.0% were overweight, and 12.5% were obese; among the boys, 15.3% were overweight, and 18.0% were obese. These prevalence rates were higher when the time spent watching TV or participating in media-related activities surpassed 5 hrs/day, when individuals belonged to a higher economic class and when the head of the family had a higher education level (≥12 years). CONCLUSION: It is important to emphasize the need to increase our understanding of factors associated with overweight and obesity, and it is essential to implement measures and policies aimed at reversing this trend, such as stimulating healthy eating habits and physical activity and reducing time spent watching TV and participating in other media activities, including video games and social networking.
