[Relationship between maximum body mass index and type 2 diabetes mellitus among adults in Heilongjiang province.].
OBJECTIVE
To determine the prevalence and distribution of type 2 diabetes mellitus (T2DM) and the relationship between maximum body mass index (MAXBMI) and T2DM.


METHODS
From June to August, 2005, a stratified cluster sampling of 1071 permanent residents in communities, over 20 years old, from 4 districts and 1 county of Mudanjiang was chosen. The prevalence of T2DM, and the association between T2DM and different levels of the MAXBMI, current BMI were studied.


RESULTS
The prevalence in the communities was 7.09% and in those with past maximum BMI >/= 28 kg/m(2), it was 12.10%. With the increase of past MAXBMI levels, the risk of T2DM patients also increased significantly (trend chi(2) = 17.387 23, P < 0.0001). Data from multifactor analysis showed that MAXBMI in the past was positively related to T2DM (OR = 3.06, P = 0.0013). In T2DM patients, the group with MAXBMI >/= 27.4 kg/m(2) had higher 2-hour postprandial blood glucose than those with lower MAXBMI (P = 0.0408). When compared with low maximum BMI group in normal blood glucose population, the group with higher MAXBMI (>/= 25.4 kg/m(2)) had higher blood glucose and greater change of BMI.


CONCLUSIONS
In both groups that patients with T2DM and with normal glucose, in order to control blood glucose better, researchers should not only concern about the influence of the MAXBMI in the past, but also pay attention to constantly keep BMI at the normal range.
