Abstract
BACKGROUND: The growing prevalence of non-communicable chronic diseases poses a significant public health challenge globally, particularly impacting the well-being of aging populations. This study aims to assess the impact of community-based public health service (PHS) on the health-related quality of life (HRQoL) among middle-aged and older adults with chronic diseases in China. METHODS: Utilizing data from the China Health and Retirement Longitudinal Study, we constructed a novel scale based on the 36-Item Short Form Health Survey (SF-36) to measure the HRQoL of middle-aged and older patients with hypertension and/or type-2 diabetes. Multivariate linear regression models with Instrument Variables and Propensity Score Matching techniques were applied to examine the effect of PHS on the HRQoL of identified chronic disease patients. RESULTS: Among 8,403 hypertensive and/or diabetic patients, only 10.98% had received PHS. After adjusting for covariates, PHS exhibited a significant association with an elevated overall SF-36 score (β = 3.539, p < 0.001). Similar effects were observed in the physical and mental component summary scores, with increases of 1.982 (p < 0.001) and 5.095 (p < 0.001), respectively. Sensitive analysis affirmed the robustness of these findings. Heterogeneity analysis revealed significant HRQoL improvements among males, females, those aged 70 and older, patients with comorbidities, and urban residents, while the effect was less pronounced in the middle-aged, those without comorbidities, or rural dwellers. CONCLUSION: Community-based PHS has exerted a positive impact on both the physiological and psychological aspects of HRQoL among middle-aged and older chronic disease patients, with effects varying among individuals with different characteristics. Our findings advocate for enhancing the delivery and utilization of government-funded PHS, increasing health literacy, and promoting early prevention strategies for chronic diseases. Furthermore, targeted health management initiatives for patients with comorbidities and enhancements in the quality of community healthcare services, particularly in rural areas, are deemed necessary.
