“…Por conta disso, aumentaria o consumo de tais alimentos durante essa atividade sedentária. Em crianças, Jackson et al 21 identificaram que a atividade física não intermedeia a relação positiva entre o tempo de TV e a gordura corporal, e que o hábito de assistir TV não esteve relacionado a um menor gasto energético total. Portanto, o tempo de TV e a obesidade devem estar ligados por outros mecanismos, e não pelo menor gasto energético.…”

Objective: To analyze associations between two physical activity domains during leisure time and different food habits in adolescents. Methods:The sample comprised 1,630 adolescents (46% male and 54% female). Physical activity level, television (TV) viewing, and eating behaviors were assessed through an interview. According to the results of the assessment, adolescents were classified as physically active or engaged in high amounts of TV viewing and unhealthy/healthy diets.Results: Male adolescents were more active than females (21.7 and 9.4%, respectively; p = 0.001), while TV viewing was more frequent in females (44.0 and 29.2%; p = 0.001). Physical activity level was related to higher consumption of fruits (OR = 1.90; 95%CI 1.39-2.60) and vegetables (OR = 1.48; 95%CI 1.09-2.01), while higher consumption of fried foods (OR = 2.13; 95%CI 1.64-2.77) and snacks (OR = 1.91; 95%CI 1.49-2.45) was associated with TV viewing. Conclusion:This study presented epidemiological information indicating that active and inactive behaviors were differently and independently associated with healthy and unhealthy diets.J Pediatr (Rio J). 2011;87(3):252-256: Physical activity, food habits, adolescents. ResumoObjetivo: Analisar associações entre dois domínios da atividade física de lazer e hábitos alimentares em adolescentes. Métodos:A amostra foi composta por 1.630 adolescentes (46% do gênero masculino e 54% do gênero feminino). O nível de atividade física, o tempo de televisão (TV) e os comportamentos alimentares foram avaliados por entrevista, e, de acordo com o resultado da avaliação, os adolescentes foram classificados como fisicamente ativos, espectadores assíduos de TV, e engajados em dietas não saudáveis/saudáveis. Resultados:Os adolescentes do gênero masculino foram mais ativos do que as do feminino (21,7 e 9,4%, respectivamente; p = 0,001), ao passo que o hábito de assistir TV foi mais frequente entre as meninas (44,0 e 29,2%; p = 0,001). Práticas de atividades físicas foram associadas com maior consumo de frutas (OR = 1,90; IC95% 1,39-2,60) e vegetais (OR = 1,48; IC95% 1,09-2,01), ao passo que o maior consumo de frituras (OR = 2,13; IC95% 1,64-2,77) e salgadinhos (OR = 1,91; IC95% 1,49-2,45) esteve associado ao hábito de assistir TV. Conclusão:Este estudo epidemiológico apresenta informações indicando que os comportamentos ativo e inativo estiveram diferente e independentemente associados aos hábitos alimentares saudáveis e não saudáveis. J Pediatr (Rio J) IntroduçãoO nível de atividade física (NAF) tem diminuído nas últimas décadas, e é considerado um dos principais fatores de risco modificáveis para uma ampla gama de doenças crônicas; por esse motivo, várias organizações e agências têm publicado recomendações sobre a quantidade adequada de atividade física para a população em geral, inclusive para os jovens em idade escolar 1,2 .

“…Ortega et al (2007) also found that the negative impact of TV viewing on WC can be attenuated with more vigorous physical activity. However, TV viewing's association with childhood obesity after controlling for physical activity has been stated a number of times (Vandewater and Huang, 2006;Jackson et al, 2009). In our study as well, the results were controlled for physical activity.…”

Health behaviors, waist circumference and waist-to-height ratio in children

et al. 2011

View full text Add to dashboard Cite

Background: Waist circumference (WC) and waist-to-height ratio (WHtR) begin to gain attention as measures of adiposity and as important cardiometabolic disease risk factors also among children. Still, little research has been done on behavioral determinants of WC and WHtR in children. The purpose of this study was to examine associations between health behaviors, WC and WHtR in children. Methods: The study was a cross-sectional study conducted in Swedish-speaking schools in Helsinki region in 2006. In all, 1146 children were recruited, from which 55 % took part in the study. A total of 604 9-11-year-old children (312 girls, 292 boys) were measured by research staff and completed a study questionnaire on their health behaviors, including breakfast intake, TV viewing, sleep duration and physical activity, and a 16-item food frequency questionnaire. Covariance analysis was used as the statistical analysis method. Results: When controlling for other health behaviors, for example, irregular breakfast (B-coefficient 2.49 CI, 0.64-4.34; Po0.01), TV viewing (B-coefficient 0.89 CI, 0.17-1.61; Po0.05), a TV in child's room (B-coefficient 2.30 CI, 0.73-3.86; Po0.01) and physical inactivity during school breaks (B-coefficient 0.78 CI, 0.19-1.37; Po0.01) were associated with larger WC. Results were similar with WHtR. Conclusions: Many health behaviors were related to children's WC and WHtR. Determinants were associated to both WC and WHtR similarly.
