Wen-Jui Han, Ph.D., from the Silver School of Social Work at New York University in New York City, examined how employment patterns throughout working lives, based on work schedules, may shape health (sleep hours and quality, physical and mental functions, and the likelihood of reporting poor health and depressive symptoms) at age 50 years. The analysis included longitudinal data from the National Longitudinal Survey of Youth-1979 with employment patterns starting at age 22 years (approximately 7,336 participants).
