Hypertension Prevalence, Awareness, Treatment, and Control Following China’s Healthcare Reform

BACKGROUND: In 2009, China started an impressive national healthcare system reform. One of the key components is to promote equity in access to essential healthcare services including chronic disease management. We assessed the changes in hypertension management and its equity before and after China's healthcare reform in 2009. METHODS: We used data from the 2008 and 2012 waves of the China Health and Retirement Longitudinal Study (CHARLS). The surveys were conducted in Zhejiang and Gansu provinces, containing 1,961 and 1,836 respondents aged 45 and older in 2008 and 2012 respectively. We measured the prevalence of hypertension, and proportions of respondents with hypertension aware of their conditions, receiving treatment and under effective control, separately for 2008 and 2012. We also reported these measures in provinces and rural/urban areas. RESULTS: From 2008 to 2012, the age standardized prevalence of hypertension was steady at 46.2%, but hypertension management improved substantially. Among those with hypertension, the proportion of patients aware of their conditions increased from 57.8% to 69.9%, the proportion of patients receiving treatment increased from 38.1% to 56.1%, and the proportion of patients with hypertension under effective control increased from 21.7% to 36.4%. The highest improvement was found in rural areas of the underdeveloped province, which indicated that the inequity across regions declined over time. CONCLUSIONS: Among Chinese population aged 45 and older in Zhejiang and Gansu provinces, hypertension management improved following healthcare reform. The rate of improvement was faster in rural and underdeveloped areas, possibly related to additional governmental subsidies to these areas.
