Key result
An increasing number of non-communicable diseases was significantly negatively associated with health utility value across all ethnic groups (p < 0.001), with more severe impacts observed in ethnic minority populations.
Why the study?
Chronic conditions among middle-aged and older ethnic minority adults are increasingly prominent, but evidence on the impact of non-communicable diseases in this population in later life remains limited.
Cross-Sectional (n=2,710)
p-value: p=<0.001
The accumulation of non-communicable diseases is associated with worse health utility, ADL, chronic pain, and frailty, with ethnic minority groups in underdeveloped regions of China experiencing more severe negative health impacts.
Ethnic minorities may experience amplified NCD-related health declines; leaves open need for targeted interventions in multi-ethnic settings.
Background Chronic conditions among middle-aged and older adults from ethnic minority backgrounds is becoming increasingly prominent, while there is limited evidence available regarding the influence of NCDs on ethnic minority groups in later life. This study aims to examine the characteristics of NCDs and health status among adults aged ≥45 in multi-ethnic settlement, as well as explore the disparate impacts of chronic condition on ethnically diverse populations. Methods This cross-sectional study was conducted in Yunnan Province, China from July to December 2022. Intergroup comparisons were performed using chi-square tests and Kruskal-Wallis H test. Multivariable linear regression and Tobit regression were used to assess the impact of NCDs on health status indicators. Results Out of the total 2,710 participants, approximately 57.90% exhibited at least one NCD, with individuals from the Han majority exhibiting a higher prevalence (p < 0.001). Individuals belong to Zhiguo ethnic minority groups had higher mean scores for ADL (15.92, SD = 3.80), chronic pain (2.27, SD = 2.28), and frailty (3.37, SD = 2.61). A significantly negative association was observed between the number of NCDs and the health utility value across all ethnic groups (p < 0.001). Conversely, there was a positive relationship between scores for chronic pain and frailty with the number of NCDs for all three ethnic groups respectively; within Zhiguo ethnic minority groups alone, there was also a positive correlation between ADL scores and the number of NCDs (p < 0.001). Conclusion The prevalence of NCDs among adults aged ≥45 in Yunnan province is significantly higher, indicating a substantial burden of NCDs in underdeveloped areas. Although the chronic condition is more prominent among Han majority, individuals belonging to Zhiguo ethnic minority exhibit poorer health outcomes. And the negative health effects from NCDs to health status are more severe among ethnic minority groups, indicating an urgent need for targeted interventions to address health disparities in multi-ethnic regions.

Deng et al. (2025) conducted a cross-sectional in Non-communicable diseases (n=2,710). Number of non-communicable diseases vs. No non-communicable diseases was evaluated on Health utility value (p=<0.001). An increasing number of non-communicable diseases was significantly negatively associated with health utility value across all ethnic groups (p < 0.001), with more severe impacts observed in ethnic minority populations.
