Objective:
The practice of parallel multiple jobs has increasingly become a global trend. However, the effects of parallel multiple jobs on physical and mental health have not been well understood.
Method:
Data come from China Health and Retirement Longitudinal Study published by CHARLS in 2015. The agricultural population aged 45 years old and above are selected through stratified random sampling (N = 10,118). Robust regression method is used to give robust estimation.
Results:
U-shape relations are found. The modest increase in the number of parallel multiple jobs can alleviate the difficulty in physical activities functioning and can reduce mental health problems. However, these beneficial effects could turn detrimental with the number of parallel multiple jobs beyond the modest level, leading to work overload.
Conclusion:
Parallel multiple jobs could be considered a double edge sword for physical and mental health.
