Linking occupational conditions to physical health through marital, social, and intrapersonal processes.

In the present longitudinal study of 330 married men and 300 married women, we use a comprehensive structural equation model to investigate how occupation is linked to physical health. Results show that occupational quality influences health-risk behavior (measured by composite indices) for both men and women through a series of mediating variables: social integration, marital integration, and psychological control. Health-risk behavior is related to adverse change in physical health status over a two-year period. Occupational quality influences social and marital integration and psychological control for both husbands and wives. Social integration and marital integration also enhance husbands' psychological control, but marital integration is the only factor contributing to wives' psychological control. In turn, psychological control is associated with health-risk behaviors for both husbands and wives. In addition, both social and marital integration directly deter husbands' health-risk behaviors, while social integration is the only variable to directly influence wives' health-risk behaviors.
