Trends in the prevalence of type 2 diabetes and prediabetes in a Japanese community, 1988-2012: the Hisayama Study.

ABSTRACT:

Objective

We estimated secular trends in the prevalence of type 2 diabetes (T2DM) and prediabetes, and examined potential explanatory factors for these trends in a Japanese community.

Methods

4 cross-sectional examinations were conducted among subjects aged 40-79 years in 1988 (n = 2,490), 2002 (n = 2,856), 2007 (n = 2,761), and 2012 (n = 2,644). Glucose tolerance status was defined by a 75g oral glucose tolerance test.

Results

The age-standardized prevalence of T2DM increased significantly in both sexes from 1988 to 2002, and thereafter it remained stable in men, and decreased nonsignificantly in women from 2002 to 2012. The age-standardized prevalence of prediabetes in men increased significantly between 1988 and 2002, but then decreased
