Abstract
Purpose
The associations of duration of subjective poverty and poverty status with mortality among older people remains inconclusive, and the underlying mechanisms of mental health on them are rarely discussed in population-based epidemiological studies.
Methods
We used the data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) (2008–2018). The Cox regression model was used to estimate hazard ratio (HR) and 95% confidence intervals (CIs) for mortality. Mediation analysis was applied to assess the effect of mental health.
Results
When compared with participants without subjective poverty, those who reported subjective poverty at one time point (2008 or 2011) or two time points (2008 and 2011) had a higher risk of death, with multivariable-adjusted HR (95% CIs) of 1.08 (1.00–1.16) and 1.22 (1.06–1.39), respectively. For poverty status, the multivariable-adjusted HR (95% CIs) of mortality were 0.81 (0.66–0.98) for “just objective poverty” and 0.78 (0.62–0.98) for “neither subjective nor objective poverty” compared with participants who reported “just subjective poverty”, while there was no statistically significant association between “poverty subjectively and objectively” and mortality (HR = 0.88, 95% CI 0.72–1.07). Besides, we found that the proportion mediated by mental health was 26.6%, and age was a significant effect modifier.
Conclusions
Subjective poverty may be associated with a higher risk of death among Chinese older people. This study showed that promoting mental health alone may not substantially reduce socioeconomic inequality in health. Further explorations of measures to tackle the social determinants of health are still needed.
