    OBJETIVO: Verificar a associação entre atividade física e características socioeconômicas com a presença de obesidade e/ou sobrepeso em crianças de seis a 14 anos, escolares da Escola Sérgio Porto e pacientes que procuraram o Ambulatório de Pediatria no Hospital de Clínicas (HC), ambos no campus da Universidade Estadual de Campinas (Unicamp). MÉTODOS: O estudo foi realizado por meio da aplicação de questionário aos pais ou responsáveis e coleta de dados de peso e altura das crianças. Foi calculado o índice de massa corpórea (IMC), e feita a classificação em normal, sobrepeso ou obesidade, a partir dos dados do Centers for Disease Control and Prevention (CDC), dos Estados Unidos. Foi feita análise descritiva dos dados e utilizados os testes do qui-quadrado ou exato de Fisher. RESULTADOS: A amostra ambulatorial foi composta por 107 crianças (13,1% com sobrepeso e 11,2% obesas) e a escolar de 109 (16,5% com sobrepeso e 20,2% obesas). Não foi observada diferença significante entre a prevalência de obesidade ou de obesidade e sobrepeso entre as duas amostras, apesar de as amostras serem diferentes em relação à renda mensal (p<0,0001), escolaridade materna (p<0,0001) e atividade física (p<0,0001), sendo que a população ambulatorial apresentou menores índices nestas três variáveis, comparada à escolar. CONCLUSÕES: Os índices de sobrepeso e obesidade encontrados no presente estudo foram elevados, confirmando que houve a transição nutricional em ambas as amostras, de maneira similar à observada no resto do nosso país, independentemente do sexo, da classificação socioeconômica e da atividade física.<br>OBJECTIVE: The aim of this study was to verify the association between physical activity and socio-economic status with the presence of obesity and/or overweight in children aged six to 14 years of two different sources: an elementary school and an out-patient Pediatric clinic of one university hospital of Campinas, São Paulo. METHODS: A socio-demographic questionnaire was answered by parents and the evaluation of children's weight and height was performed according to Centers for Disease Control and Prevention (CDC), USA, standards for body mass index (BMI) The children were divided in three categories: normal, overweight and obese. Chi-square and Fisher exact test were used to compare both groups of children. RESULTS: 107 children from the university hospital were studied (13.1% with overweight and 11.2% obese) as well as 109 from the elementary school (16.5% overweight and 20.2% obese). Both groups were similar regarding the prevalence of obesity alone or obesity and overweight. Groups differed in family income (p<0.0001), number of maternal years in school (p<0.0001) and physical activity (p<0.0001), with disadvantage of the clinic patients. CONCLUSIONS: The frequency of overweight and obesity observed in this study were high, pointing out that a nutritional transition has occurred in both samples independently of gender, socio-economic status and physical activity

    Investigou-se a relação entre o estado nutricional e a situação sócio-econômica familiar de adolescentes moradores de Niterói, Rio de Janeiro, Brasil. Os dados de 523 adolescentes, pertencentes a uma amostra probabilística de 1.734 domicílios, foram coletados entre janeiro e dezembro de 2003 e representam os 71.922 jovens residentes em Niterói. As análises incluíram a estimação de intervalos de confiança de razões de prevalência e testes de distribuições proporcionais e de independência entre classes de estado nutricional e classes de renda familiar per capita e as faixas de número de moradores do domicílio. Foi encontrada uma associação positiva significativa entre baixo peso/magreza e o número de moradores do domicílio (sexo masculino: p < 0,05; sexo feminino: p < 0,001). O número de moradores do domicílio encontra-se diretamente associado ao baixo peso/magreza em adolescentes. Foi evidenciada uma tendência positiva de aumento na proporção de adolescentes com sobrepeso/obesidade segundo os quintos de renda familiar per capita.<br>This study focused on the relationship between nutritional and socioeconomic status among adolescents in Niterói, Rio de Janeiro State, Brazil. Data from 523 adolescents living in 1,734 households were collected from January to December 2003, from a total of 71,922 adolescents living in Niterói. Subjects were selected through a probabilistic household sample. The analyses included the estimation of confidence intervals for prevalence ratios and proportional distributions and independence tests between categories of nutritional status and per capita family income and number of residents per household. There was a significant positive association between underweight/thinness and number of residents in the same household (male: p < 0.05; female: p < 0.001). Number of residents in the same household was positively associated with prevalence of underweight/thinness in adolescents. Overweight/obesity was positively associated with per capita family income

    Background: Spinal pain is an important health issue for adolescents resulting in functional limitations for many and increasing the risk of spinal pain in adulthood. Whilst human and animal studies suggest nutrition could influence spinal pain, this has not been investigated in adolescents. The objective of this exploratory cross sectional study was to evaluate associations between diet and adolescent spinal pain. Methods: This study surveyed the spinal pain (neck and back) and nutrition (specific nutrients, broad food groups, diet quality and dietary pattern) of 1424 male and female adolescents at 14 years of age, in Western Australia. Results: Back or neck pain were experienced by around half of the adolescents, with females more likely to experience spinal pain. Nutrition differed between sexes and deviated from optimal intakes. Vitamin B12, eggs, cereals and meat consumption were related to spinal pain in sex specific multivariate analyses including primary carer education level and adolescent waist girth and smoking. Conclusions: The findings of this study suggest that certain aspects of diet may have an association with spinal pain in adolescence
