Abstract
The prevalence of non-insulin-dependent diabetes mellitus (NIDDM) as defined by WHO criteria was studied in a rural community of Hiroshima. All the inhabitants over the age of 30 were asked to participate in this study, during the month of December in 1990 and 1991. Eventually, 307 males (23.2%) and 620 females (41.5%) agreed to participate and had an oral glucose tolerance test (75g of glucose).
The crude prevalence rates of NIDDM were 11.4% for males and 6.9% for females, and the adjusted prevalence rates by population in 1985 were 9.5% for males and 4.5% for females, respectively.
The results suggest that both males and females over the age of 50 showed a higher-rate of prevalence than those under the age of 50.
