Prevalence of overweight/obesity and its association with sedentary behavior in children

Objective: The aim of this study was to determine the prevalence of overweight and obesity in children in the northeast region of Portugal, and to examine its association with sedentary behavior. Methods: Data were collected on 1786 children (907 boys, 879 girls) aged 6 to 13 years. Body mass index...

description Objective: The aim of this study was to determine the prevalence of overweight and obesity in children in the northeast region of Portugal, and to examine its association with sedentary behavior. Methods: Data were collected on 1786 children (907 boys, 879 girls) aged 6 to 13 years. Body mass index was calculated from measured height and weight (weight in kg/height in m squared). Overweight and obesity were determined using the International Obesity Task Force cutoff values. Sedentary behavior was assessed based on means of transport to and from school and time spent watching TV and playing video games (TVPC). Results: The prevalences of overweight and obesity were 22.6% and 9.4% respectively. The differences between the sexes for both overweight and obesity were not significant. Most of the children (78.4%) go to school by car. Boys spend more time on TVPC than girls, both on weekdays and on weekends. The logistic regression model indicated a significant effect of 1.5 hours of TVPC by boys during weekdays (OR=0.246; p=0.015). Boys who spent less than 1.5 hours on weekdays on TVPC were 75.4% less likely to be overweight than those who spent more than 1.5 hours. Conclusion: The prevalence of overweight and obesity was 32%. Only 12.2% of the children spend less than 1.5 hours on TVPC. Boys who spend less than 1.5 hours on TVPC are 75.4% less likely to be overweight/obese than those who spend more than 1.5 hours. Resumo: Objectivo: determinar a prevalência de sobrepeso/obesidade em crianças da região Nordeste de Portugal, e analisar sua associação com o sedentarismo. Métodos: Os dados foram recolhidos em 1786 crianças (n = 907 meninos, meninas n = 879) com idades entre os 6 e 13 anos, o índice de massa corporal foi calculado a partir da estatura e peso [massa corporal (kg) / Altura (m2)] medidos. O sobrepeso/obesidade foram determinados usando os valores de corte da IOTF. O comportamento sedentário foi avaliado tendo em conta: o meio de transporte e tempo gasto a ver televisão/jogar videojogos (TVPC). Resultados: a prevalência de sobrepeso/obesidade foi de 22,6% e 9,4%, respetivamente. As diferenças entre os sexos, tanto para o sobrepeso como para a obesidade, não foram significativas. A maioria das crianças usa o automóvel (78,4%) para ir à escola. Os meninos gastaram mais tempo em TVPC que as meninas, tanto durante a semana como nos fins de semana. O modelo de regressão logística indicou um efeito significativo de 1,5 horas de TVPC para os meninos, durante a semana (OR = 0,246; p = 0,015). Os meninos que gastaram menos de 1,5 horas durante a semana em actividades TVPC foram 75,4% menos propensos a serem obesos do que aqueles que gastaram mais de 1,5 horas. Conclusão: a prevalência de sobrepeso/obesidade atinge 32%. Apenas 12,2% gastam menos de 1,5 horas em TVPC. Os meninos que passam menos de 1,5 horas em TVPC são 75,4% menos propensos a ter sobrepeso/obesidade do que aqueles que gastam mais de 1,5 horas.
