Lazer sedentário e consumo de alimentos entre adolescentes brasileiros: Pesquisa Nacional de Saúde do Escolar (PeNSE), 2009

Abstract

The objective of this paper was to investigate whether sedentary leisure time was associated with increased regular consumption of unhealthy foods, independently of socio-demographic indicators and family context. The analysis included 59,809 students from the Brazilian National School-Based Adolescent Health Survey (PeNSE) in 2009. The response variable was sedentary leisure time, defined as watching more than two hours of TV daily. The target explanatory variables were regular consumption of soft drinks, sweets, cookies, and processed meat. Odds ratios (OR) and 95% confidence limits (95%CI) were obtained by multiple logistic regression. Prevalence of sedentary leisure time was 65%. Regular consumption of unhealthy foods was statistically higher among students reporting sedentary leisure time, before and after adjusting for sex, age, skin color, school administration (public versus private), household assets index, and household composition. The results indicate the need for integrated interventions to promote healthy leisure-time activities and healthy eating habits among young people.

Consumption of sugar-rich food products among Brazilian students:National School Health Survey (PeNSE 2012)

“…Moreover, a study that used data from PeNSE 2012 showed a poorer quality diet among girls compared with boys 30 , suggesting that Brazilian female adolescents are more exposed to inadequate food consumption 29,30 . The finding regarding the association gradient between a higher amount of time spent watching TV and more elevated consumption of sugar-rich food products among adolescents is also consistent with evidence from other studies 17,31,32,33,34 . Evidence suggests that behavioral risk factors, such as the habit of watching TV, or lengthy screen time, and inadequate food consumption, have an influence on one another, tending to coexist in the form of a cluster, resulting in added risk of the development of overweight and comorbidities 32 .…”

“…Evidence suggests that behavioral risk factors, such as the habit of watching TV, or lengthy screen time, and inadequate food consumption, have an influence on one another, tending to coexist in the form of a cluster, resulting in added risk of the development of overweight and comorbidities 32 . This coexistence can be justified by the elevated exposure of adolescents with higher screen time to advertisements of food products with elevated calorie content, such as sweets and soft drinks, favoring the consumption of those food groups instead of products with less media exposure, such as fruits and vegetables 14,17,31 .…”

“…Studies suggest that adolescents who do not live with their mother and father have an increased chance of having several risk behaviors, including smoking, alcohol and other drugs use, and sedentary behavior 15,31 . This relationship derives from a possible lack of support and adequate monitoring of adolescents who do not live with their parents 15,31 .…”

This relationship derives from a possible lack of support and adequate monitoring of adolescents who do not live with their parents 15,31 . Having meals in the presence of parents/ guardians encourages family cohesion, since it favors moments of interaction among its members, in addition to providing lower consumption of fried foods and soft drinks and a higher intake of dairy and fruits and vegetables 15,29,30,39 .…”

Hábito de assistir à televisão e sua relação com a alimentação: resultados do período de 2006 a 2014 em capitais brasileiras

“…Porém, poucos estudos analisaram essa relação com vistas, especialmente, ao consumo alimentar de adultos em países em desenvolvimento 42 . No Brasil, a maioria dos estudos realizados é dedicada a avaliar essas relações apenas em crianças ou adolescentes 43,44 , ou restringem sua abordagem à análise da associação entre o hábito de assistir à TV e a prática de atividade física 45,46 .…”
