Abstract
To analyze socioeconomic and demographic factors associated with physical activity level among workers. Cross-sectional study conducted in Brazil's Federal District, from 2000 to 2001, with a representative sample of 1,044 workers from both sexes, who are covered by the Programa de Alimentação do Trabalhador (Workers' Food Program). Binary logistic regression was used to determine possible risk factors associated with physical activity level and selected by the backward elimination process. Interactive effects of the variables were verified in the final model by means of the odds ratio for physical activity level >1.4. The final model included sex, income and level of education. Male individuals who only finished elementary school and earned less than four Brazilian minimum wages per month were the most likely to show physical activity level >1.4. The odds ratio estimate indicated that men were five times more likely to show physical activity level >1.4 than women. Individuals who only finished elementary school and had an income equal to or below four minimum wages were two times more likely to show physical activity level >1.4 than individuals who earned more than four minimum wages and had a university degree or higher. Results indicate that the factors associated with physical activity level among workers are the following: male, elementary school level, and income below four Brazilian minimum wages per month.

The sample was calculated according to the official list of restaurants that are in partnership with the PAT in the Federal District, provided by the Ministério do Trabalho e do Emprego (MTE – Ministry of Labor and Employment) and combined with the list of restaurants registered in the Conselho Regional de Nutrição - 1a região – CRN-1 (Regional Council of Nutrition – 1st region)
Summary
Non-communicable diseases and conditions result from a group of risk factors, and are characterized as multi-causal. According to the World Health Organization (WHO), some of these factors are related to diet and physical activity, having an impact on people’s quality of life.[14]. Innumerable associations between physical activity and non-communicable diseases and conditions have been found.[9,12,14,16,19] As regular physical activity can prevent gain of weight, in addition to improving physical performance, mortality and morbidity can be reduced. As a result of changes in life and working conditions, the number of people who practice regular physical activity is small. In Brazil, around 13% of adult individuals practice leisure physical activity with some regularity, of which male practice surpassed female practice in terms of length of time and frequency.[6,12,16]
