MID-LIFE JOB STRESS AND SUPPORT PREDICT SLEEP HEALTH TRAJECTORIES THROUGHOUT ADULTHOOD

Good sleep is necessary for healthy aging, but it may be threatened by work stress. This study connected midlife job characteristics to trajectories of sleep health profiles (within-person configurations of key self-reported facets: duration, regularity, sleep onset latency or SOL, insomnia symptoms, feeling unrested, and napping) over one decade. A working adult sample (N=847, Mage=45) of the Midlife in the United States study provided data on sleep and job characteristics in 2004-2006 (T1) and 2013-2016 (T2). Four sleep profiles were consistently identified at both time points: (1) good sleepers, (2) irregular but sufficient, (3) short sleepers, and (4) long SOL/insomnia. Higher job demands at T1 predicted a transition from good or irregular/sufficient sleep at T1 to long SOL/insomnia at T2. Higher workplace social support at T1 predicted maintenance of good or irregular/sufficient sleep over time. Attention to job demands and workplace social support may help promote sleep health.
