Impact of disease screening on awareness and management of hypertension and diabetes between 2011 and 2015: results from the China health and retirement longitudinal study

Abstract

Background There has been a limited recognition of hypertension and diabetes in China which has compromised optimal treatment. It is not clear if a screening program implemented by a national health survey has improved awareness and management of these conditions. Methods The China Health and Retirement Longitudinal Study (CHARLS) is an ongoing longitudinal health survey conducted since 2011 among Chinese people aged 45 years and older. Participants have been assessed every two years by interviews, physical examinations, and fasting glucose samples were taken in 2011. In 2013 and 2015, participants were asked about awareness and management of selected chronic diseases, and they first became aware of these conditions. Results Of the 11,000+ participants screened in 2011, 4594 were identified with hypertension and 1703 with diabetes by medical examinations. Over 80% of the middle-aged and elderly Chinese diagnosed with hypertension and/or diabetes in 2011 reported in 2015 that they were unaware of the disease(s). Although some improvement was observed between 2011 and 2015, the main reason for the increase in awareness was a medical examination initiated by the study participant (over 75%), by their work unit or community (12–15%), and rarely (less than 3%) by the CHARLS examination. Participants with a rural household registration status and lower BMI were the most likely to be unaware and to remain unaware of their condition(s). Conclusions Disease screening in CHARLS did not lead to significant improvements in awareness of hypertension and diabetes. Improvements should be made by the systematic feedback of screening results to survey participants and the monitoring of disease awareness over time. This will be essential to improve disease recognition and facilitate optimal management.

Factors associated with treatment and control of hypertension among elderly adults in Shenzhen, China: a large-scale cross-sectional study

“…Several previous epidemiological studies have reported on the treatment of hypertension in Chinese elderly populations. 18 19 One of those studies, the China Health and Retirement Longitudinal Study, measured the treatment of hypertension in a nationally representative sample of 9357 Chinese aged 45 years or above, which provided the best comparison data for our study. 18 When compared with the findings from that study, the treatment of hypertension in this study indicated higher incidence, 51.0% vs 54.4%, respectively.…”

Urban and Rural Disparities in Healthcare Utilization and Expenditures Among Rural Hukou Beneficiaries of New Cooperative Medical Scheme in China

“…However, rural migrants are also constrained by many barriers when we have a close look. These barriers include lack of knowledge of NCMS, difficult reimbursement policies, and lack of health awareness [14][15] [16] [17]. Accordingly, an uncertainty of the direction of disparity distribution among NCMS beneficiaries was raised.…”

The Impact of Illness Awareness on the Difference in the Economic Burden of Disease Among Middle-Aged and Elderly Diabetic Patients in Rural Areas

“…Patients who are judged to be diabetes and have no consciousness of illness are judged to be diabetes without consciousness of illness, a patient who is judged to be a diabetes with a illness consciousness is judged to be a patient with a illness consciousness diabetes. [9] The data screening process is shown in Figure 1.…”
