Weekly Working Hours and Mental Health Status in Different Occupations Evidence From the 2015 to 2016 California Health Interview Survey

摘要

Objective: The aim of this paper was to identify shapes of the curves between weekly working hours (WWH) and mental health status (MHS) and determine WWH for the best MHS in 13 occupations. Methods: This cross-sectional study applied public data of the 2015 to 2016 California Health Interview Survey. Restricted cubic spline regression was used to determine non-linear trends. Results: A statistically significant nearly V-shaped curve was demonstrated between WWH and MHS in total population, men and management, business and finance occupations. WWH for the best MHS were 42, 45, and 46 hours, respectively. Conclusion: These results suggest MHS be susceptible to WWH in total population, men and management, business and finance occupations. WWH for the best MHS for relevant populations could provide evidence for better work hours regulations in California.
