Methods According to the guideline of experimental epidemiology, two city communities were selected as intervened community and controlled community respectively in Shandong province.In the year of 1997, the baseline data in both of the two communities were collected and a DM community intervention program in the intervened community was implemented.In the year of 2001, the related data were collected again with the same criteria and methods in the two communities.By the comparison of the baseline data and the data of 4 years later, the effectiveness of community intervention on healthy population's body mass index(BMI), waist to hip ratio(WHR), leisure physical activity intensity and dietary composition were analyzed.
Results In the intervened community, there was no significant difference between the baseline and 4 years later data in the aver age of BMI or WHR, while the average in the controlled community rose after 4 years(P < 0.05).There was no significant difference was found in the prevalence of over weight or fat in the intervented community, but in the controlled community, overweight raised by 12.1% and fat raised by 5.6%(P < 0.01), No difference in leisure physical activity in intervened community while the proportion of middle level decreased from 47.6% to 14.2%(P < 0.01).
