0241 Sleep Across the Lifespan in Hispanic/Latinx Adults

Abstract

Abstract Introduction Studies examining racial/ethnic sleep disparities have observed that minoritized individuals are more likely to experience poor sleep compared to non-Hispanic whites. Existing research on Hispanic/Latinx (H/L) individuals further reinforces this assertion. However, to date, little attention has been paid to lifespan examinations of sleep within minoritized groups. The present study assessed sleep characteristics differences across the lifespan within a large sample of H/L adults. We hypothesized that older adults would report more concerns and symptoms associated with impaired sleep. Methods Participants included 1,072 (63.3% female; µ=36.43) adults who self-identified as H/L and completed an online survey assessing insomnia symptoms (Insomnia Severity Index), sleep-related daytime impairment (PROMIS Sleep-Related Impairment), sleep regularity (Sleep Regularity Questionnaire), subjective sleep quality (Pittsburgh Sleep Quality Index), and self-reported sleep duration. A One-Way ANOVA was utilized to detect mean differences in sleep markers across age groups [Young (18-25), Middle (30-50), and Late adulthood (55+)]. Significant mean differences were further analyzed with Duncan’s post hoc analysis. Results The One-Way ANOVA revealed significant mean differences across all sleep markers analyzed: insomnia symptoms, F(2, 1069)=67.459, p<.001; sleep-related daytime impairment, F(2, 1069)=77.465, p<.001; sleep regularity, F(2, 1069)=74.091, p<.001; sleep quality, F(2, 1069)=29.300, p<.001; and total sleep duration, F(2, 1069)=5.898, p=.003. Post hoc analyses revealed significantly more insomnia symptoms (µ=14.325) and poorer sleep quality (µ=1.623) in late adulthood compared to younger (µ=8.270; 1.092) and middle-aged (µ=10.186; 1.345). As well as significant elevations in sleep-related daytime impairment (µMiddle=22.314; µLate=23.508) and poorer sleep regularity (µMiddle=16.556; µLate=16.704) in middle and late adulthood compared to younger adults (µ=16.056; 13.054). Lasty, young adults slept (µ=6.756) significantly less than middle and late adulthood (µMiddle=7.025; µLate=7.162). Conclusion Results suggest that age is important factor in the consideration of sleep among H/L adults. These findings generally point to an increase in poor sleep as age increases. It’s important to consider this trend when working with minoritized individuals due to the disproportionate burden of sleep factors being potentially compounded by age.
