“…It is important to appreciate that there may be subpopulations of women for whom night shift work is particularly detrimental to reproductive health. We believe such subpopulations exist, given the suspected effects of psychosocial stress and sleeplessness on ovarian function, 62 and bearing in mind that not all women with poor tolerance to shift work can choose to avoid it. Women with other reproductive problems predisposing them to difficulties in conceiving and maintaining a pregnancy could also plausibly be at higher risk than other shift workers.…”

Fixed or Rotating Night Shift Work Undertaken by Women: Implications for Fertility and Miscarriage

This review summarizes the evidence concerning effects of night shift work on women's reproductive health, specifically difficulty in conceiving and miscarriage. We distinguish between fixed night shift and rotating night shift, as the population subgroups exposed, the social and biological mechanisms, and the magnitude of effects are likely to differ; of note, women working fixed night shift are known to have high tolerance for this schedule. We identified two relevant systematic reviews with meta-analyses and five additional studies. Night shift work may give rise to menstrual cycle disturbances, but effect sizes are imprecise. Endometriosis may be elevated in night shift workers, but evidence is only preliminary. Adequate data are lacking to assess associations between night shift work and infertility or time to pregnancy. The weight of evidence begins to point to working at night, whether in fixed or rotating shifts, as a risk factor for miscarriage. There are many methodological problems with this literature, with substantial variation in the definitions of night shift and schedule types making comparisons between studies difficult and pooling across studies questionable. Nevertheless, there appears to be grounds for caution and counselling where women have concerns about night shift work and their reproductive health.

“…The risk of OSA increases with older age, obesity, male gender, smoking, alcohol intake, sedative use, menopause, and in certain ethnicities [19]. Similar to PCOS, OSA is a health burden in affected individuals and it is associated with increased risk of hypertension [21], CVD [22][23][24], mortality [25,26], insulin resistance (IR) and T2DM [27], road traffic accidents [28], depression and impaired QoL [29][30][31], as well as subfertility [32].…”

The prevalence of obstructive sleep apnoea in women with polycystic ovary syndrome: a systematic review and meta-analysis

et al. 2019

Background Obesity is a common risk factor for polycystic ovary syndrome (PCOS) and obstructive sleep apnoea (OSA). Both PCOS and OSA are associated with increased risk of type 2 diabetes and cardiovascular disease. Hence, it is important to determine the burden of OSA in women with PCOS. Methods We searched electronic databases (MEDLINE, Embase, CINAHL, PsycINFO, Scopus, Web of Science, OpenGrey, CENTRAL), conference abstracts, and reference lists of relevant articles, up to January 2019. No restriction for language or publication status. Studies that examined the presence of OSA in women with PCOS using polysomnography and/or level III devices were eligible for inclusion. Results Seventeen studies involving 648 participants were included. Our meta-analysis showed that 35.0% (95% CI 22.2-48.9%) of women with PCOS had OSA. This prevalence was not affected by variation in PCOS definition between studies. Approximately one-tenth of the variation in OSA prevalence was related to differences in study population (higher in adults than adolescents and mixed populations), and around one-tenth was related to sample size (higher in smaller studies). OSA prevalence was markedly higher in obese versus lean women with PCOS, and in women with PCOS compared to controls (odds ratio = 3.83, 95% CI 1.43-10.24, eight studies, 957 participants (349 PCOS and 608 controls)). However, most of the studies were at high risk Abd A. Tahrani and Harpal S. Randeva are joint senior authors and contributed equally to the manuscript.

“…7 Sleep disturbances have been observed right from the first trimester of pregnancy till the end of the third trimester. 8 However, the percentage of sleep disorder and sleep disturbances are more in the third trimester of pregnancy. 9 To our dismay, a change in sleep pattern is associated with adverse pregnancy outcomes both in the Venugopal L et al Int J Res Med Sci.…”

A study on assessment of sleep quality in south Indian pregnant women

2018

Background: Sleep disturbances are common during pregnancy. The risk of sleep disturbances is estimated to be two times higher in the later part of pregnancy compared to the early trimester. Thus, the present study was planned to assess the sleep quality in different trimesters of South Indian pregnant women.Methods: This was a descriptive cross-sectional questionnaire-based study. A total of 90 healthy pregnant women with a mean age of 25 years were recruited and sleep quality was assessed using a standardized PSQI questionnaire. Mean global PSQI score of ≥5 is suggestive of poor sleep quality. A p value <0.05 was considered statistically significant.Results: Subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications and daytime medication were found to be significantly higher in the second and third trimester (p<0.0001) pregnant women. Mean global PSQI score was ≥5 in the third trimester pregnant women.Conclusions: The present study shows that the sleep quality is disturbed during pregnancy and it is more in the third trimester of pregnancy. Pregnant women should be aware of the effects of sleep deprivation and adverse outcomes related to it. Thus, proper identification of sleep disturbances and a good awareness on the cumulative effects of the risk factors associated with sleep deprivation during pregnancy will help the physicians to manage and prevent the adverse maternal and fetal outcomes.
