Abstract
Excessive daytime sleepiness (EDS) is the tendency to sleep at inappropriate times during the day. It can interfere with day-to-day activities and lead to several health issues. The objective of this study was to investigate the association between income, housing conditions, and incidence of EDS in adults living in two Cree First Nations communities. The data for this study involved 317 individuals aged 18 years and older who participated in baseline and follow-up evaluations (after four years) of the First Nations Lung Health Project, which was conducted in Saskatchewan in 2012–2013 and 2016. Both at baseline and follow-up survey after four years, an Epworth Sleepiness Scale (ESS) score >10 was considered to be abnormal. Logistic regression models were used to assess relationships between abnormal ESS and covariates at baseline. In 2016, 7.6% (24/317) of the participants reported an ESS >10 with the mean being 12.8 ± 2.0. For the same group, the mean ESS at baseline was 6.9 ± 2.2. The incidence of subjective EDS based on the ESS >10 was estimated at 7.6% over four years. This study showed an association between incidence of subjective EDS and less money left over at end of the month, having a house in need of repairs, having water or dampness in the past 12 months, and damage caused by dampness.
Highlights
Sleep timing, a key aspect of sleep behavior, varies largely within the population [1]
We observed that boys with a delayed pubertal development had a significantly earlier chronotype than the male database control cohort of the same age (n = 19) (Figure 2A; Table 2)
Sleep timing did not differ between the 10 girls with a premature thelarche and the controls (Figure 2B, Table 2)
Summary
A key aspect of sleep behavior, varies largely within the population [1]. Clocks&Sleep 2019, 1, 13 between individuals who wake up early in the morning and individuals who wake up late in the day This variation in sleep timing has been used as a proxy for chronotype, or the individual phase of entrainment [2,3,4,5,6,7]. Adolescents on average have a later phase of entrainment and this is paralleled by their sleep timings, especially on non-school days when sleep timing is not affected by school start times, but at least in part regulated by the circadian system This phase delay leads to a mismatch with early school and work start times, a phenomenon referred to as social jetlag [14]. Higher levels of social jetlag have been associated with adverse metabolic profiles and obesity [12,15,16,17,18,19,20,21]
