The objective of the present study was to find out the appropriate BMI cut-off point in relation to type 2 diabetes mellitus (DM) in the population of Kavre district of Nepal.
Thirty-five "known type 2 diabetic" and Thirty-five "self-reported non-diabetic" subjects above thirty years of age were included in the present study. Height and weight were recorded for every subject. BMI was calculated by the standard formula. The data was analyzed using SPSS Version 11.5.
Our results showed that the reference BMI range for both diabetic male (23.26 +/- 6.88 kg/m(2)) and diabetic female (22.51 +/- 6.28 kg/m(2)) subjects were within normal BMI range according to WHO. Odds ratio showed an irregular pattern at different BMI ranges indicating the risk of having diabetes did not increase constantly. Comparison of number and percentage of both diabetic and non-diabetic male and female subjects according to various recommended normal BMI categories showed gradual reduction in percentage of both diabetic and non-diabetic male and female subjects that were within normal ranges from BMI category 18.5-24.9 kg/m(2) to BMI category 18.5-21.9 kg/m(2). The BMI cut-off point was found 22 kg/m(2) using Receiver Operating Characteristic (ROC) curves.
The appropriate BMI cut-off point for both men and women was found 22 kg/m(2) in the population of Kavre district of Nepal.
本研究的目的是找出尼泊尔卡夫雷地区人群中与2型糖尿病（DM）相关的合适体重指数（BMI）切点。
本研究纳入了35名“已知2型糖尿病患者”和35名年龄在30岁以上“自我报告非糖尿病患者”。记录每位受试者的身高和体重。采用标准公式计算BMI。使用SPSS 11.5版对数据进行分析。
我们的结果显示，根据世界卫生组织标准，糖尿病男性受试者（23.26±6.88kg/m²）和糖尿病女性受试者（22.51±6.28kg/m²）的参考BMI范围均在正常BMI范围内。比值比在不同BMI范围内呈现不规则模式，表明患糖尿病的风险并非持续增加。根据各种推荐的正常BMI类别，对糖尿病和非糖尿病男性及女性受试者的数量和百分比进行比较，结果显示，从BMI类别18.5 - 24.9kg/m²到BMI类别18.5 - 21.9kg/m²，处于正常范围内的糖尿病和非糖尿病男性及女性受试者的百分比逐渐降低。使用受试者工作特征（ROC）曲线得出BMI切点为22kg/m²。
在尼泊尔卡夫雷地区人群中，男性和女性的合适BMI切点均为22kg/m²。
