Sleep quality in women who use different contraceptive methods

Background Both menstrual cycle and hormone alterations influence sleep pattern. The aim of this study was to evaluate sleep quality in women who use different contraceptive methods. Material and Methods This study was a descriptive, cross-sectional survey. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality, and a questionnaire was used to obtain sociodemographic, clinical, lifestyle, and contraceptive use data. Results The study population comprised 235 women in reproductive age. Regarding lifestyle, 25.5% of the women were physically active, 12.3% were tobacco-smoking, and 70.6% drank coffee daily. Sleep quality was good in 34% of the studied population and poor in 66% of the population. The population was divided into two groups: hormonal (57.1%) and non-hormonal (42.9%) contraceptive users. Sleep quality in the users of non-hormonal contraceptive methods was similar to that in the users of hormonal methods (6.1±3.2 versus 5.9±2.9; p=0.5). Sleep efficiency was statistically higher among the users of non-hormonal contraceptive methods (94.7±17.7) than among the users of hormonal methods (90.0±15.3; p=0.03). The patients who had irregular or altered menstrual cycles reported poorer sleep quality. The absence of routine physical activity negatively influenced sleep quality (p=0.05). The women who snored reported worse sleep quality (p=0.002). Conclusions Nearly half of the studied population was users of hormonal contraception, and most of these women reported poor sleep quality. Sleep efficiency was higher among the users of non-hormonal contraceptives. No differences in subgroups (hormonal contraceptive users) were observed.
