Résumé
Abstract The aim of the present study was to analyze the relationship between time spent engaged in sedentary behaviors, type of diet, and overweight in adolescents. A cross-sectional study using data from the Longitudinal Study on Sedentary Behavior, Physical Activity, Eating Habits, and Health of Adolescents - LONCAAFS Study. A total of 1,438 adolescents (10 to 14 years old) from public schools in the city of João Pessoa, Brazil, participated in the study. To evaluate the combined effects of excessive time in sedentary behavior and consumption from two food groups: Convenience and Prudent on overweight, we performed multiple logistic regression analyses, adjusted for energy, level of physical activity, sex, and age. Excessive time in sedentary behavior increased the chance of adolescents being overweight by 37% (OR = 1.37; 95%CI: 1.04-1.80). This chance increased to 43% when the adolescents were simultaneously engaged in excessive sedentary behavior and had high consumption of the Convenience food group (OR = 1.43; 95%CI: 1.05-1.94) and increased to 39% on those who engaged in excessive sedentary behavior and had low consumption of foods from the Prudent (OR = 1.39; 95%CI: 1.04-1.84). Excessive sedentary behavior is associated with being overweight and the chance increases with the consumption of convenient foods.
Resumo O objetivo do estudo foi analisar a relação entre tempo gasto em comportamentos sedentários, dieta e excesso de peso em adolescentes. Estudo transversal com dados do Estudo Longitudinal sobre Comportamento Sedentário, Atividade Física, Hábitos Alimentares e Saúde do Adolescente - Estudo LONCAAFS. Participaram 1.438 adolescentes (10 a 14 anos) de escolas públicas de João Pessoa, Brasil. Para avaliar os efeitos combinados do tempo excessivo no comportamento sedentário e no consumo de dois grupos de alimentos: Conveniência e Prudente sobre o excesso de peso, foram realizadas análises de regressão logística múltipla, ajustadas para energia, nível de atividade física, sexo e idade. O tempo excessivo em comportamento sedentário aumentou em 37% a chance de os adolescentes apresentarem excesso de peso (OR = 1,37; IC95%: 1,04-1,80). Essa chance aumentou para 43% quando os adolescentes apresentaram, simultaneamente, comportamento sedentário excessivo e alto consumo do grupo de alimentos de conveniência (OR = 1,43; IC95%: 1,05-1,94), e aumentou para 39% naqueles com excesso de comportamento sedentário e baixo consumo de alimentos do Prudente (OR = 1,39; IC95%: 1,04-1,84). O comportamento sedentário excessivo está associado ao excesso de peso e a chance aumenta com o consumo de alimentos convenientes.
Résumé
Aim: To evaluate the effects of an intervention for the prevention of obesity on the prevalence of dental caries disease in Spanish children. Methods: Two cities participated intervention study nested in a cohort IDEFICS (Identification and prevention of dietary and lifestyle induced health effects in children and infants): Huesca, where there was a 2-year intervention, which encouraged less sugar consumption; and Zaragoza (control). The prevalence of caries was evaluated by examining the 1st permanent molars in the 7-11 age range, using the ICDAS (International Caries Detection and Assessment System). These teeth erupt at 6 years of age and at the baseline (2007-2008) were free of caries because they were not present in the oral cavity. As outcomes, white spots were selected, combining the ICDAS criteria 1 and 2, and untreated caries, combining criteria 4, 5 and 6. Their association with socioeconomic variables, BMI (Body Mass Index), frequency of sugar intake, sex and parents' perceptions of their children, was investigated. To do so, the chi-square test was applied (p<0.05). Results: The sample consisted of 281 children. The prevalence of white spots and untreated caries was higher in Huesca, despite the intervention. There was no association between the outcomes and the variables studied (p>0.05). Conclusion: The intervention for the prevention of obesity did not exert any association with the prevalence of caries in Spanish children
