Factors associated to the practice of physical activity by Brazilian workers

Abstract

The factors associated with the practice of physical activity among Brazilian workers
were evaluated. It is a descriptive, analytical, cross-sectional, quantitative study conducted with
82,019,207 workers by means of the National Survey by Household Sample of 2015. So to verify
the association of physical activity practice among workers, Odds Ratio (OR) was estimated at
p<0.05 by means of a logistic regression model with a 95% Confidence Interval (CI). It was noted
that only 31.7% of the workers practiced physical activity. The practicing probability decreased
with age increasing, especially for males between 46 and 55 years old (OR 0.626, CI 0.565-0.693),
as well as for female workers with children under 14 years old (OR 0.569, IC 0.474-0.682) facing
high working hours. The practice of formal workers is 17.9% higher than among informal workers.
Also, the increase in schooling as in salaries raised the chance by, respectively, 5.719 for those with
15 years or more of study and by 2.365 for those between 12 and 15 minimum salaries of income.
Finally, the military personnel enjoyed a greater chance of practicing physical activity (OR 5.586,
IC 3.572-8.736).
