The Study On The Effect Of Community-based Lifestyle Intervention On High Risk Group Of Non-communicable Diseases In Shenzhen

Objective: To evaluate the effect of community-based intervention on lifestyle,dietary intake and biochemical indicators among high risk group of NCDs from Futian District of Shenzhen,and to provide theoretical basis for the prevention and treatment of NCDs and the formulation of public health policies.Methods: Twelve communities were randomly selected from Futian District,Shenzhen City in 2016.High risk group of NCDs were screened from the selected communities and divided into intervention group(4 communities)and control group(8communities).The general characteristics,lifestyle and dietary information among high risk group of NCDs were collected and physical examinations were performed before and after intervention.After over-night fasting,venous blood of the participants was collected,and the serum TC,TG,LDL-C and HDL-C were detected by AU640 automatic biochemical analyzer,and the serum FBG was determined by enzymatic method.The intervention participants received a 3-year of community-based intervention program consisting of health education activities and any other support in making lifestyle changes while the control group did not receive any active intervention activities.Differences in Differences(DID)methods were used to evaluate the effect of the lifestyle intervention among high risk group of NCDs.Results: A total of 1192 subjects(676 in the intervention group,516 in the control group)were included in the present study.After intervention,average consumption of cereals and tubers,aquatic products,milk and dairy products,eggs,soybean and nuts and vegetables in the intervention group increased by91.8,33.0,30.9,26.6,49.7 and 66.8g/d(P<0.05 or P<0.01).The proportion of participants whose consumption met Chinese Balance Dietary Pagoda(2016)increased significantly.Compared with the control group,SBP and DBP in the intervention group were decreased by 3.45 and 2.01 mm/Hg,while HDL-C,TG,and FBG were increased by 0.19,0.29,0.28mmol/L,and LDL-C was decreased by0.33mmol/L(P<0.05 or P<0.01).The proportion of abnormal SBP and DBP and WC decreased by 15.8%,4.9% and 9.5%,respectively.After intervention,the rate of weight control,oil usage control and the skills of control salt and oil increased by12.2%,22.4%,7.7% and 9.7% respectively(P<0.05 or P<0.01).Conclusions: After 3 years of lifestyle intervention,participants with high risk of NCDs in the intervention group have more reasonable dietary structure and healthy lifestyle,and blood pressure,TC,HDL-C,LDL-C levels and WC were significantly improved,but the effect of intervention on TG and FBG was not obvious.
