The long-term effectiveness of sleep medications among women in midlife should be re-evaluated. These findings, from a longitudinal cohort study, were published in BMJ Open.

Community-dwelling women were recruited for the Study of Women’s Health Across the Nation (SWAN) at 7 sites in the United States between 1995 and 1997. Follow-up data between 2014 and 2016 for propensity-matched women (N=685) with some sleep disturbances were analyzed for sleep quality and medication use.

At baseline, study participants were aged mean 49.5 (standard deviation [SD], 8.5) years, BMI was 29.1 (SD, 7.4) kg/m2, 57.5% were White, 46.1% had hypertension, 44.2% osteoarthritis, and 42.9% were postmenopausal. Most women (n=447) did not use sleep medications.

Women in the medication and no medication groups had trouble initiating sleep 3 nights per week (34.5% vs 30.7%), waking frequently 3 nights per week (66.4% vs 65.1%), early morning awakening 3 nights per week (34.0% vs 30.2%), and any disturbance 3 nights per week (76.9% vs 72.0%) at baseline, respectively.

At the 1- and 2-year follow-up, sleep disturbances were not significantly changed among either cohort, except, non-users of sleep medications had lower early morning awakening scores at year 1 (P =.02) but not at year 2 (P =.92).

Among only benzodiazepine users, no significant differences were observed for sleep disturbances compared with the non-user group (all P =.17). Among women who used selective benzodiazepine receptor agonists and other hypnotics, no differences were observed for difficulty initiating sleep (P =.12) or early morning awakening (P =.28), but waking frequently during sleep was significantly reduced among the non-user group (P =.05).

This study may have been limited by relying on self-reported sleep difficulties.

These data did not support long-term sleep medication use, as there was no improvement in self-reported sleep disturbances among women in midlife. Additional study is needed especially due to the fact that sleep disturbances are common, and the use of sleep aids has been increasing.
