Prevalence and factors associated with the use of sleep-inducing medication among women receiving Primary Health Care: a cross-sectional study in Vitoria, Espirito Santo, Brazil, 2014

Objective: To verify prevalence and factors associated with the use of sleep-inducing medication among women receiving primary health care (PHC) in Vitoria, ES, Brazil. Methods: This was a cross-sectional study conducted in 2014 with women aged 20-59. We analyzed association of sleep-inducing medication use with socioeconomic factors and experiences of violence (Poisson regression). Results: Out of 991 participants, 18.5% were using sleep-inducing medication and 45.9% had used it at some point in their lives. Current and lifetime use of these medications was associated with age, years of education, as well as psychological, physical and sexual violence in the last year (p-value<0.05). Lower family income (PR=1.30; 95%CI 1.03;1.64) and controlling partner (PR=1.35; 95%CI 1.08;1.69) were associated with current use, while experience of sexual violence in childhood (PR=1.33; 95%CI 1.13;1.56) was associated with lifetime use. Conclusion: Use of sleep-inducing medication was frequent among PHC service users, and was associated with socioeconomic factors and experiences of violence.
