Abstract: ObjectiveTo investigate the effect of family doctor signing service on the health of the elderly in the community.MethodsElderly people aged 65 years and over, who participated in free medical examination in a community health service center in Huadu District, Guangzhou in March 2016, were recruited as study subjects. Among them, those who signed family doctor services voluntarily were taken as the signing group, and those who did not sign family doctor services were classified as the control group. The signing group was managed by family doctor service team, and the control group, by public health doctors for routine follow-up. Body mass index (BMI), blood pressure (BP), fasting blood glucose (FBG), total cholesterol (TC), triglycerides, low-density lipoprotein cholesterol (LDLC), and high-density lipoprotein cholesterol (HDLC) were tested and compared before and after intervention for one year between two groups. Logistic regression analysis was used to analyze the related factors.ResultsA total of 304 people were investigated, including 170 in the signing group and 134 in the control group. Before intervention, there were no statistical differences in abnormal rates of BMI, BP, FBG, TC, triglyceride, LDLC, and HDLC between the 2 groups (all P>0.05). After intervention, except for the BMI, the abnormal rates of BP, FBG, TC, triglyceride, LDLC, and HDLC in the signing group were lower than those in the control group (all P<0.05). Logistic regression analysis showed that family doctor signing service was the influencing factor of BP, FBG, triglyceride, and HDLC.ConclusionFamily doctor signing service could improve the normal rate of BP, FBG, triglyceride, and HDLC in the elderly, and effectively improve their health status.
