Introduction: This study explored the associations between sleep duration and emotion regulation among urban black women (mean age = 59 ± 7 yrs).

Method: Eligible women (n = 523) provided sociodemographic data during face-to-face interviews. We used the Comprehensive Assessment and Referral Examination Physical to measure health status; women also estimated their habitual sleep duration. We utilized a modified version of Weinberger’s conceptual model of repression, the Index of Self-Regulation (ISE) to measure emotion regulation. ISE scores were derived by amalgamating the defensive subscale from the Social Desirability Scale and the anxiety subscale from the State-Trait Anxiety Inventory.

Results: The median habitual sleep duration was 7 hours; 20% of the women were short sleepers (<6 hours) and 6% were long sleepers (>8 hours). Short sleepers, rather than long sleepers, had a greater likelihood of reporting insomnia symptoms than those sleeping 6-8 hours [63.4% vs. 28.1%; X2 = 41.87, p<0.001]. In the first logistic regression model, the odds of being a short sleeper for low regulators were 3 times greater than for high regulators [OR = 3.22 95% CI: 2.05-5.06; p<0.0001]. In multivariate-adjusted analysis, OR was reduced to 2.06, but remained significant. In the second logistic model, the likelihood of being a long sleeper among low regulators were 37% greater than for high regulators, but results were not significant [OR = 1.37, 95% CI: 0.62-3.01; NS].

Discussion: Short and long sleep duration are associated with reduced ability for emotion regulation. Women sleeping 6-8 hrs might be more adept at regulating emotions in their daily lives. Insomnia symptoms might mediate associations between emotion regulations and sleep durations.
