Differential Impact of an Education-Based Intervention for Patients with Type 2 Diabetes Mellitus in Rural China.

The study aimed to assess the impact of an education-based intervention to improve vertical integration and management of type 2 diabetes mellitus in primary care in rural China. Patients with type 2 diabetes mellitus in three townships in Jingjiang county, Jiangsu Province were randomly divided into intervention and control groups. Participants in the intervention group received an education-based intervention. Patients' data including the fasting blood glucose (FBG) level, health-related quality of life (HRQoL), and sociodemographic characteristics were collected at baseline (2015) and follow-up (2016). The FBG levels decreased significantly in the intervention group compared to the control group in the overall analysis. In the stratified analysis, FBG levels and some aspects of HRQoL improved in the intervention group more for females, married persons, those with low education, and those in farming or house working. Participants in the control group deteriorated in FBG levels but improved in some aspects of HRQoL. The intervention improved in FBG levels and some aspects of HRQoL among participants. Furthermore, the intervention seemed to differentially benefit females, married persons, lowly educated persons, and those in farming or house working more than other groups.
