Public expenditure on health care and the incidence of non-communicable diseases (NCDs) in China from 2008 to 2018

Abstract

ObjectivesThis study investigates whether differences in individual-level and provincial-level health funding could explain or mitigate health inequalities among older people in terms of non-communicable diseases within a population served by fragmented health insurance schemes. Study designA national repeated cross-sectional analysis was done of the 2008, 2011, 2014, and 2018 Chinese Longitudinal Healthy Longevity Surveys. These provided a total of 44,623 persons aged 60 and over. Main outcome measuresRespondents were asked whether they had been diagnosed with any types of non-communicable diseases by doctors. A dichotomous outcome variable was constructed to indicate whether older people had any diagnosed non-communicable diseases. ResultsCompared with uninsured older persons, those who were enrolled in social health insurance schemes designed for civil servants as cadres, urban employees and urban residents were more likely to report a higher incidence of non-communicable diseases. There were no significant differences in the prevalence of non-communicable diseases between uninsured older people and those in the New Rural Cooperative Medical Scheme. Although the incidence of non-communicable diseases among older persons increased over the study period, greater health expenditure was significantly associated with a lower risk of non-communicable diseases. The interaction results between individual social health insurance schemes and public health expenditure indicate that disparities in the incidence of non-communicable diseases among different health insurance schemes diminish as public health expenditure increases. Older individuals with Public Free Medical Services benefited the most in provinces with higher public health expenditure compared with other health insurance schemes. ConclusionsGiven the evidence of the beneficial effects of universal health coverage on non-communicable diseases among older persons, these results should encourage policy makers to increase public health funding and to raise the overall benefit packages for social health insurance schemes.
