Factors associated with sleep quality in adolescent pregnant women.

Objective: To verify the association of sociodemographic, anthropometric, obstetric, lifestyle factors, and depressive symptoms with sleep quality in pregnant adolescents.

Method: This cross-sectional study involved pregnant adolescents aged 10 to 19 who received prenatal care in Recife, Pernambuco, Brazil. Data collection included an individual evaluation form and the administration of the Pregnancy Physical Activity Questionnaire (PPAQ), the Pittsburgh Sleep Quality Index (PSQI), and the Beck Depression Inventory (BDI). Prevalence and associations were calculated using Pearson's chi-square test or Fisher's exact test, followed by logistic regression analysis.

Results: The study included 386 pregnant adolescents with a mean age of 17 ± 2 years. The prevalence of poor sleep quality was 67.5%. Poor sleep quality was associated with moderate to severe depressive symptoms (OR = 2.21; 95%CI 1.27-3.85), higher education levels (OR = 2.26; 95%CI 1.43-3.57), and the presence of gestational physical symptoms (OR = 1.18; 95%CI 1.10-1.27).

Conclusion: Pregnant adolescents exhibit a high prevalence of poor sleep quality, which is linked to depressive symptoms, higher education levels, and gestational physical symptoms. These findings highlight the importance of screening for sleep disorders in this population and emphasize the need for guidelines addressing physical symptoms and their impact on sleep, as well as the presence of depression.
