The prevalences of diabetes mellitus and impaired glucose tolerance (IGT) among 866 Indians living in the Chatsworth area of Durban were determined. The study group was selected by cluster sampling and the participants underwent a modified glucose tolerance test (GTT) (determination of fasting and 2-hour plasma glucose levels after a 75 g glucose load). On the basis of the revised World Health Organization criteria the overall prevalence of diabetes mellitus was 11% and of IGT 5,8%. Of the 368 men, 7,6% were found to have diabetes mellitus and 7,1% IGT; the prevalence of diabetes mellitus was much greater among women (13,5%), while there was less IGT (4,8%). Subjects with diabetes mellitus were significantly older (mean 50,7 years) than those with a normal GTT (mean 30,9 years), but of similar age distribution compared with the IGT group (mean 46 years). Subjects with a normal GTT had a significantly lower mean body mass index (22,1 +/- 2,8) compared with diabetic subjects (26,1 +/- 5,2) or the IGT group (25,8 +/- 6,6). Obesity was commonly associated with both diabetes mellitus and IGT, particularly among women.
对居住在德班查茨沃思地区的866名印度人的糖尿病和糖耐量受损（IGT）患病率进行了测定。研究组通过整群抽样选取，参与者接受了改良糖耐量试验（GTT）（75克葡萄糖负荷后测定空腹及2小时血浆葡萄糖水平）。根据世界卫生组织修订标准，糖尿病总体患病率为11%，IGT为5.8%。在368名男性中，发现7.6%患有糖尿病，7.1%有IGT；女性糖尿病患病率（13.5%）远高于男性，而IGT患病率（4.8%）低于男性。糖尿病患者的年龄（平均50.7岁）显著高于糖耐量正常者（平均30.9岁），但与IGT组（平均46岁）年龄分布相似。糖耐量正常者的平均体重指数（22.1±2.8）显著低于糖尿病患者（26.1±5.2）或IGT组（25.8±6.6）。肥胖通常与糖尿病和IGT都有关联，尤其是在女性中。
