Trend analysis of the lifestyle of pregnant women in Brazil between 2007 and 2017.

We aimed to analyze lifestyle trends of Brazilian pregnant women from 2007 to 2017 and their association with sociodemographic factors. This was time-series study using data from Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (VIGITEL). Lifestyle indicators were: regular consumption (≥ 5x/week) of beans, vegetables, chicken, meat, fruit, milk, and soft drinks, alcohol and tobacco uses, and practice of physical activity (PA). Variance-weighted linear regression was used to obtain average annual variation (percentage points-pp) of indicators, and Poisson regression was used to verify the association of sociodemographic factors and indicators. There was an increase in chicken consumption (+0.74pp/year), practice of PA (+1.36pp/year); reduction in consumption of soft drinks (-1.64pp/year) and tobacco (-0.26pp/year). Pregnant women aged > 20 years had a higher prevalence of raw vegetables and milk and a lower of meat and soft drinks. Pregnant women with ≥ 9 years of schooling had a higher prevalence of consumption of vegetable, fruit, PA practice and a lower prevalence of meat, chicken, soft drinks and tobacco use.
