Psychosocial Stressors, Poor Sleep Quality Linked

Sleep; 2016 Jul 1; Johnson, Lisabeth, Lewis, et al

Psychosocial stressors are associated with higher odds of short sleep, lower average sleep duration, and lower sleep quality in African Americans, a recent study found. Researchers examined cross-sectional associations between psychosocial stressors and sleep duration and quality in a large population sample of African Americans (n=4,863), using the Jackson Heart Study (JHS) baseline data. Mean age was 54.6 years and 64% were female. They found:

• Mean sleep duration was 6.4 + 1.5 hours, 54% had a short sleep duration, 5% had a long sleep duration, and 34% reported a “poor” or “fair” sleep quality.

• Persons in the highest Global Perceived Stress Scale (GPSS) quartile had higher odds of very short sleep, higher odds of short sleep, and shorter average sleep duration and reported poorer sleep quality compared to those in the lowest quartile of GPSS after adjustment for covariates.

• Effects of stress on sleep duration were stronger for younger (<60 years) and college-educated African Americans.
