Food consumption and its association with leisure-time physical activity and active commuting in Brazilian workers.

Background/objectives: An in-depth understanding of the relationship between food consumption and physical activity is relevant since these behaviours could influence each other, while both have an effect on obesity and chronic diseases. In this context, the aim of this study was to investigate the effect of various combinations of food consumption (fruits, vegetables, sweets and snacks) on the associations with PA domains (leisure and commute) among Brazilian industrial workers.

Subjects/methods: This is part of a cross-sectional national survey developed in Brazil using data from the "Lifestyle and Leisure Habits of Industrial Workers" project.

Methods: Secondary analysis of the survey "Lifestyle and leisure habits of industry workers" (n=46,981), conducted in 24 Brazilian states (2006-2008). Self-reported information was collected with a previously tested questionnaire.

[Socio-demographic factors associated with three sedentary behaviors in Brazilian workers].

This study focused on the association between socio-demographic characteristics and three sedentary behaviors among industrial workers in Brazil. Data were analyzed on 47,477 workers from 24 Brazilian states, collected by questionnaires from 2006 to 2008. Individual and simultaneous presence of ≥ 4 hours of TV time per day, commuting by car or motorcycle, and sitting most of the time at work were investigated, as well as associations between these behaviors and gender, age, schooling, and family income.

Clustering of unhealthy behaviors in a Brazilian population of industrial workers.
