Investigation on Current Situation of T2DM in Ganzhou City and Countryside and Analysis of Correlation Factors

Abstract

Objective: to study the current situation and distributional characteristics of T2DM in Ganzhou city and countryside and to explore the correlation factors of T2DM. Methods: the baseline of T2DM and its correlation factors was investigated in the 35- to 64-year-old residents in Ganzhou by multiple horizon Hierarchies random sampling method from 2009 to 2016. The WHO diagnostic code of 1999 was adopted for the diagnosis of T2DM. Results: the prevalence of T2DM and IFG in Ganzhou was 7.7% (683/8906) and 13.1% (1,167/8,906) respectively. The prevalence of T2DM was 9.6% (283/2947) and 14.9% (112/751) in overweight population and obesity population respectively which was higher than in BMI normal population [6.7% (289/4317), x2=62.185, P<0.001]. The prevalence of IFG was 21.5% (634/2947) and 25.5% (192/751) in overweight population and obesity population which was obviously higher than in BMI normal population [16.2% (699/4317), x2=55.191, P<0.01]. The prevalence of T2DM and IFG in hypertension population was 12.4% (306/2469) and 23.7% (457/1929) which was obviously higher than in non-hypertension population [7.0% (369/5274),x2=19.309, P<0.001 and 17.1%(705/4121),x2= 14.474, P<0.001]. The prevalence of T2DM and IFG in hyperlipemia population was 12.3% (297/2412) and 23.7% (451/1902) respectively which was obviously higher than in non-hyperlipemia population [6.2% (319/5152),x2=61.709, P<0.001 and 17.7% (709/4003), x2=15.674 , P<0.001]. The prevalence of male T2DM and IFG was 8.5% (383/4504) and 13.2% (479/3630) respectively. The prevalence of female T2DM and IFG was 7.0% (296/4224) and 19.4% (660/3404) respectively. There was not statistically significant between the male and female T2DM (x2 =3.208, P=0.073), but there was statistically significant between the male and female IFG (x2 =29.222, P<0.001). The prevalence of T2DM and IFG in city was 8.0%(349/4366) and 20.0% (670/3350). The prevalence of T2DM and IFG in countryside was 7.3%(240/3293) and 19.4% (490/2527) respectively. There was not significant in T2DM or IFG between in the city and in the countryside (x2=0, P=1 and x2=0.193, P=0.660). Conclusion: the prevalence of T2DM and IFG in Ganzhou city and countryside was severe. The health education should be carried out for moderate and small city which has just recently transformed and been rich. The early screening for T2DM should be evolved through the onset risk prediction model of T2DM in order to decrease the prevalence of T2DM.
