Perceived stress and associated factors in pregnant women: a cross-sectional study nested within a population-based cohort

Abstract

Abstract Objectives: to estimate the prevalence of perceived stress and verify the associated factors in pregnant women assisted by Family Health teams in Montes Claros, Minas Gerais - Brazil. Methods: epidemiological, cross-sectional, and analytical study, nested in a population-based cohort. Sociodemographic and obstetric characteristics and physical and mental health conditions were assessed. The stress level was estimated by the Perceived Stress Scale (PSS-14). Descriptive and bivariate analyses were conducted, followed by the Poisson Regression model with robust variance. Results: a total of 1,279 pregnant women participated. The prevalence of high-stress levels was 23.5% (CI95%=20.8%-26.2%). The outcome was more prevalent among pregnant women aged above 35 years (PR=1.38; CI95%=1.09-1.74) and less than or equal to 19 (PR=1.41; CI95%=1.13-1.77); without a partner (PR=1.33; CI95%=1.09-1.62); with low social support (PR=1.42; CI95%=1.18-1.70); multiparous (PR=1.30; CI95%=1.02-1.66); with current unplanned pregnancy (PR=1.23; CI95%=1.00-1.52); urinary tract infection (PR=1.35; CI95%=1.12-1.62); high level of anxiety symptoms (PR=1.42; CI95%=1.18-1.71); severe (PR=4.74; CI95%=3.60-6.26) and moderate (PR=3.19; CI95%=2.31-4.39) symptoms of depression; and neurological complaints (PR=1.77; CI95%=1.27-2.47). Conclusions: there was a significant prevalence of high perceived stress among pregnant women, an outcome associated with sociodemographic, clinical, obstetric, and emotional factors, which demonstrates the need for comprehensive care of pregnant women’s health.
