The mediating roles of physical exercise and social-psychological stress in the relationship between socioeconomic status and self-rated health

This study confirms that physical exercise and social-psychological stress play partial mediating roles in the association between SES and SRH. The findings suggest that limited physical exercise and higher levels of social-psychological stress may adversely affect health, particularly with low SES. Promoting healthy lifestyles and supportive social environments is therefore crucial for improving population health.
