Abstract:Abstract: Objective To explore the effect of the utilization of National Basic Public Health Service (NBPHS) on the regular medication behavior and glycemic control of patients aged 35 and over with type 2 diabetes, and to provide support for the health management practice of type 2 diabetes patients in China.Methods Based on the multi-stage stratified sampling method, a questionnaire survey was conducted in 10 community health service centers or township health centers in Zhejiang Province, Shanxi Province and Chongqing City in China from November to December 2019. The data of socio-demographic characteristics, utilization of NBPHS in the last year, regular medication in the last six months and glycemic control were collected. And the effect of national basic public health service utilization on the regular medication rate and glycemic control rate of type 2 diabetes patients was analyzed by logistic regression. sensitivity analysis were applied.Results A total of 1527 patients aged 35 and over with type 2 diabetes were recruited, with the proportion of 41.00% men, 66.08% aged 65 and over and the course of 10 years and above accounted for 39.64%. The survey showed that the regular medication rate was 89.26%, the glycemic control rate was 65.23%, and the score on utilization of NBPHS was 11.83±2.246 (range 0-15) . With the more utilization of NBPHS, regular medication rate in patients with type 2 diabetes increased (χ2 trend =4.816, P<0.05), the glycemic control rate was no statistical trend (χ2 trend =0.080, P>0.05). Multivariate regressions showed that secondary school and above (OR=2.20), longer duration of disease (OR 5-9 years =1.62, OR 10 year and above =3.92) and higher utilization score of NBPHS(OR Q3=2.01) are protective factors of the regular medication; compared to local resident, domestic resident population (OR =0.54) is a risk factor. Unmarried or divorced or widowed (OR =0.61) and longer duration of disease (OR 10 years and above =0.60) are risk factors for satisfactory glycemic control, and increased monthly income per household (OR 2000-5000 yuan=1.52 , OR More than 5000 yuan =1.76) is a protective factor for satisfactory glycemic control.Conclusion The utilization of NBPHS has promoted the regular medication rate of patients with type 2 diabetes, and the higher utilization takes better effect. Emphasis should be paid on patients with low education, non-local resident, short duration of disease and without couple and strengthen their utilization of NBPHS and promote the change of their health awareness and health behavior.
