Methods: 12 out of 115 communities were randomly selected in Futian district of Shenzhen city from October to November, 2013, and 1 923 cases were screened by multiple ways as high risk groups of chronic diseases. High risk groups of chronic diseases were divided into intervention group (1 338 cases, from five residential communities and three villages within city) and control group (585 cases, from four residential communities). The intervention group received group based health education activities as well as lifestyle intervention. The intervention group was provided with health management which was mainly lifestyle intervention. No intervention was implemented in the control group. All participants were followed up over two years. 1 563 participants (1 002 in intervention group and 561 in control group) were followed up from October to November, 2015. The changes of lifestyle related outcome indicators were analyzed to examine the effect of intervention. Results: In the intervention group, 21.8% (219 persons) in high risk groups of chronic diseases became healthy individuals and 15.2% (152 persons) became patients with chronic diseases. In the control group, 9.6% (54 persons) in high risk groups of chronic diseases became healthy individuals and 20.5% (115 persons) became patients with chronic diseases. The outcome of the intervention group was better than that of the control group and the difference was statistically significant (χ2=-5.67, P<0.001). The proportion of people who knew how to correctly use of oil control pot in the intervention group increased from 61.00% (61/100) to 80.00% (280/350). The proportion of people who took oil control measures in the intervention group increased from 36.43% (365/1 002) to 56.99%(571/1 002). The changes in the intervention group were statistically different (P<0.001), but there was no statistical difference in the control group over the years (P>0.05). The proportion of people who knew how to correctly use of the salt restriction spoon increased from 81.95% (109/133) to 97.99% (342/349). The proportion of people who took salt control measures increased from 45.61% (457/1 002) to 62.67% (628/1 002) in the intervention group. The changes in the intervention group were statistically different (P<0.001). There was no statistical difference in the control group over the years (P>0.05).
