Obesity is a risk factor for type 2 diabetes mellitus. Insulin resistance is associated with visceral subcutaneous fat content. Neck circumference (NC) is a marker of upper body subcutaneous adipose tissue distribution.
The aim of this study is to compare NC in diabetics and non-diabetics and to correlate NC with other anthropometric measures.
A cross-sectional study was conducted in 350 type 2 diabetics and 350 non-diabetics of >30 years of age. Anthropometric parameters like body mass index (BMI), waist circumference (WC), hip circumference, and NC were measured. Independent t-test and Pearson's correlation were the tests of significance done to analyze quantitative data.
There was positive correlation of NC, BMI, and index of central obesity. The NC in diabetics was significantly higher than in non-diabetics (P < 0.001). NC >36 cm in diabetics and >37 cm in non-diabetics was the best cutoff value to determine subjects with central obesity.
The findings indicated that NC may be used both in clinical practice and in epidemiologic studies as a straightforward and reliable index. It is an economical easy to use test with less consumption of time and correlates well with other standard anthropometric parameters.
肥胖是2型糖尿病的一个风险因素。胰岛素抵抗与内脏及皮下脂肪含量相关。颈围（NC）是上身皮下脂肪组织分布的一个指标。
本研究的目的是比较糖尿病患者和非糖尿病患者的颈围，并将颈围与其他人体测量指标进行关联。
对350名30岁以上的2型糖尿病患者和350名非糖尿病患者进行了一项横断面研究。测量了体重指数（BMI）、腰围（WC）、臀围和颈围等人体测量参数。采用独立t检验和Pearson相关性分析对定量数据进行显著性检验。
颈围、BMI与中心性肥胖指数呈正相关。糖尿病患者的颈围显著高于非糖尿病患者（P < 0.001）。糖尿病患者颈围>36 cm和非糖尿病患者颈围>37 cm是确定中心性肥胖患者的最佳截断值。
研究结果表明，颈围可作为一个直接且可靠的指标用于临床实践和流行病学研究。它是一种经济、易于使用、耗时少的检测方法，且与其他标准人体测量参数相关性良好。
