Abstract:

Objective: To evaluate the adequacy of total gestational weight gain (GWG) according to maternal characteristics of Brazilian adolescents. Methods: Cross-sectional, hospital-based study. A total of 3.904 teenagers with a single fetus gestation and gestational age (GA) at birth ≥37 weeks were included. A hierarchical model was built to analyze the dependent variables adequacy of the GWG and independent: sociodemographic, care, obstetric and behavioral characteristics. Results: The chances of insufficient GWG were higher for adolescentsthe North (OR=1.50, 95%CI: 1.07 – 2.10) and Northeast (OR=1.68, 95%CI: 1.27 – 2, 21). Paid work increased the chances of insufficient (CI95%: 1.15 – 2.39) and excessive (CI95%: 1.01 – 1.86) GWG. The pre-pregnancy body mass index of overweight or obesity was associated with excessive GWG (OR=1.86, 95%CI: 1.19 - 2.92 and OR= 3.06, 95%CI: 2.10 - 4.45, respectively), as well as GA ≥42 weeks (OR=2.23, 95%CI: 1.03 – 4.81). Conclusion: Reside in the North and Northeast regions increases the chances of adolescents having insufficient GWG. Having paid work was associated with a greater chance of excessive and insufficient GWG. Furthermore, pre-pregnancy overweight or obesity and GA ≥ 42 weeks increased the chances of excessive GWG.
