Fatores associados à adequação do ganho de peso gestacional de adolescentes brasileiras / Factors associated with the adequacy of gestational weight gain among Brazilian teenagers

RESUMO

Resumo O objetivo deste artigo é avaliar a adequação do ganho de peso gestacional total (GPT) segundo características maternas de adolescentes brasileiras. Estudo transversal e de base hospitalar. Foram incluídos 3.904 adolescentes com gestação de feto único e idade gestacional (IG) ao nascimento ≥ 37 semanas. Foi construído um modelo hierarquizado para analisar as variáveis dependentes e a adequação do GPT e das independentes: características sociodemográficas, assistenciais, obstétricas e comportamentais. As chances de GPT insuficiente foram maiores para as adolescentes do Norte (OR = 1,50; IC95%: 1,07-2,10) e Nordeste (OR = 1,68; IC95%: 1,27-2,21). O trabalho remunerado elevou as chances de GPT insuficiente (IC95%: 1,15-2,39) e excessivo (IC95%: 1,01-1,86). O índice de massa corporal pré-gestacional de sobrepeso ou obesidade associou-se ao GPT excessivo (OR = 1,86; IC95%: 1,19-2,92 e OR = 3,06; IC95%: 2,10-4,45, respectivamente), bem como a IG ≥ 42 semanas (OR = 2,23; IC95%: 1,03-4,81). Residir nas regiões Norte e Nordeste aumentou as chances de as adolescentes apresentarem GPT insuficiente. Exercer trabalho remunerado esteve associado a maior chance de GPT excessivo e insuficiente. Além disso, o sobrepeso ou obesidade pré-gestacional e IG ≥ 42 semanas ampliaram as chances de GPT excessivo.

ABSTRACT

Abstract The scope of this article is to evaluate the adequacy of total gestational weight gain (GWG) according to maternal characteristics of Brazilian adolescents. It involved a 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 and independent variables adequacy of GWG: sociodemographic, care, obstetric and behavioral characteristics. The chances of insufficient GWG were higher for adolescents from the 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 (95%CI: 1.15-2.39) and excessive (95%CI: 1.01-1.86) GWG. The pre-pregnancy body mass index of overweight or obese adolescents 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). Living 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 excess weight or obesity and GA ≥ 42 weeks increased the chances of excessive GWG.
