Objective To investigate Hangzhou resident’s obesity cases and the relationship between body mass index(BMI),waist to hip ratio(WHR)and the prevalence rate of diabetes mellitus(DM)and impaired glucose tolerance(IGT). Methods Stratified cluster sampling method was applied,and totally 4 682 persons were randomly selected from two communities in urban area and two towns in suburban area.They were all older than 15 and had lived there for more than 5 years.They did the questionnaire and their height,weight,waistline,and hip perimeter were tested.Their blood glucose before meal and two hours after taking 75g oral glucose was tested separately. Results The rate of Hangzhou residents with overweight and obesity(BMI≥24)reached 34.39%.Among them,those with abdomen obesity reached 53.95%;and the prevalence rates of DM and IGT were 4.59% and 7.07% respectively.The prevalence rates of DM and IGT in the group with overweight and obesity were significantly higher than that in the group with normal or lightweight(OR were 2.02 and 2.82 respectively,95% CI were 1.50～2.72 and 1.87～4.28 respectively).In the group with abdomen obesity,the prevalence rates of DM and IGT reached 8.02% and 10.29% respectively,which were significantly higher than that in the group with normal weight(OR was 2.83,95% CI was 2.15～3.73). Conclusions Obesity is one of the important risk factors of DM and IGT.Education on DM is necessary and intervention measures such as diet control,proper exercise,and weight reducing to fat population should be taken.
