摘要
Background: About 4% to 12% of women in their fertile age suffer from polycystic ovarian syndrome (PCOS). Typically, women with PCOS report higher symptoms of depression, insomnia, and stress. To improve psychophysiological PCOS-related stress and insomnia, melatonin may have favorable effects. Accordingly, the present study aimed to investigate among women with PCOS, if melatonin improved symptoms of sleep disturbances and depression, compared to a placebo condition. Methods: A total of 72 women (mean age: 31.21 years) with PCOS-related infertility were randomly assigned either to the melatonin or to the placebo condition. Melatonin/placebo intake lasted for six consecutive weeks (3 mg/d). At baseline and six weeks later at study end, participants completed a series of self-rating questionnaires on sleep patterns (Insomnia Severity Index (ISI); Pittsburgh Sleep Quality Index (PSQI); obstructive sleep apnea (OSA); restless legs syndrome (RLS)) and depression. After the study, participants underwent intracytoplasmic sperm injection (ICSI). Results: OSA- and RLS-related values did not vary over time and within and between the melatonin and placebo conditions. Over time and irrespective of the melatonin or placebo condition, scores for insomnia decreased (significant p-value and medium effect size). Over time, scores for sleep disturbances descriptively decreased in the melatonin condition and descriptively increased in the placebo condition (medium effect size for the Time by Condition interaction). Next, scores for depression decreased descriptively over time, and irrespective of the study condition (always medium effect sizes). Conclusions: The pattern of results suggests that, among women with PCOS and compared to placebo, overall, the effect of melatonin on sleep patterns and depression was modest. Future studies might focus on further standardized psychotherapeutic interventions, such as CBTi, to improve sleep and mood and to decrease PCOS-related psychosocial stress.
