Abstract:
To compare the prevalence of self-reported abnormal sleep duration and excessive daytime sleepiness in pregnancy among Māori (indigenous New Zealanders) and non-Māori women versus the general population, and to examine the influence of socio-demographic factors.Self-reported total sleep time (TST) in 24-hrs, Epworth Sleepiness Scale scores and socio-demographic information were obtained from nullipara and multipara women aged 20-46 yrs at 35-37 weeks pregnant (358 Māori and 717 non-Māori), and women in the general population (381 Māori and 577 non-Māori).After controlling for ethnicity, age, socio-economic status, and employment status, pregnant women average 30 min less TST than women in the general population. The distribution of TST was also greater in pregnant women, who were 3 times more likely to be short sleepers (≤6 h) and 1.9 times more likely to be long sleepers (>9 h). In addition, pregnant women were 1.8 times more likely to report excessive daytime sleepiness (EDS). Pregnant women >30 years of age experienced greater age-related declines in TST. Identifying as Māori, being unemployed, and working at night increased the likelihood of reporting abnormal sleep duration across all women population in this study. EDS also more likely occurred among Māori women and women who worked at night.Pregnancy increases the prevalence of abnormal sleep duration and EDS, which are also higher among Māori than non-Māori women and those who do night work. Health professionals responsible for the care of pregnant women need to be well-educated about the importance of sleep and discuss sleep issues with the women they care for.
