Hormonal contraceptives alter hormone levels in women and have been linked to alterations in sleep patterns; however, previous studies yielded inconsistent results and lacked generalizability. This study examines hormonal contraceptive use and its impact on sleep outcomes, including sleep duration and sleep disturbances.Women self-reported their sleep patterns and use of contraceptives in the 2017 population-based Behavioral Risk Factor Surveillance System Survey (n=1,970). Participants were categorized by use of hormonal or non-hormonal contraceptives for the purpose of pregnancy prevention. Sleep duration was defined as having met the recommended sleep levels of 7-9 hours per 24 hours. Sleep disturbances were defined as trouble falling asleep, staying asleep, or sleeping too much ≥ 6 days within a 14-day period. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated to examine the association between contraceptive use and each sleep outcome. SAS-callable SUDAAN was used for analyses to account for the complex sampling design.Women who used hormonal contraceptives had 6% higher prevalence of sleep disturbances (PR: 1.06, 95% CI: 0.99, 1.14) and 17% lower prevalence of not meeting sleep duration recommendations (PR: 0.83, 95% CI: 0.71, 0.98) compared to those who used non-hormonal contraceptives after adjustment for age.These findings suggest the use of hormonal contraceptives may have negative impacts on sleep disturbances, and positive effects on sleep duration among women using contraceptives for preventing pregnancy. Future studies should be conducted in diverse populations utilizing objective measurements of sleep patterns. |
