Multiple chronic conditions among older adults in China: differences in socio-demographic characteristics.

OBJECTIVE

There are relatively few studies on multiple chronic conditions (MCC) among older adults in China. This study sought to assess the potential differences in the risk of MCC among different elderly populations, and thus to identify the most vulnerable populations at higher risk of developing the MCC.

METHODS

A sample of 5320 adults aged 60 years or above from the China's Health-Related Quality of Life Survey for Older Adults 2018 (CHRQLS-OA 2018) were included in this study. Descriptive statistics frequencies and proportions were used to summarize the sample characteristics, and logistic regression models were conducted to identify the differences in the risk of having MCC among different populations.

RESULTS

Overall, 52.6% of respondents had been clearly diagnosed with at least one chronic disease with 25.3% having MCC. The males ((adjusted odds ratio [AOR] = 0.84; 95% confidence interval [CI] = 0.73-0.98) were less likely to have MCC. This was also true among female elderly with a non-agricultural hukou (AOR = 0.75; 95% CI = 0.57-0.99). The elderly with a non-agricultural hukou aged 60-64 (AOR = 0.55; 95% CI = 0.34-0.88) had a lower risk of having MCC. Those whose average annual household income per capita were 15,000-30,000 RMB (AOR = 1.42; 95% CI = 1.03-1.96) were more likely to suffer from MCC. The odds ratios of having MCC were smaller as the personal savings increases in total samples (all P < 0.05).

CONCLUSIONS

The findings suggest that different policies or approaches should target these specific populations who are most in need and are most likely to suffer from MCC.
