To analyse overweight, obesity and central fat patterning among the Inuit of Greenland and Inuit migrants in Denmark and their relation to Westernization.
Cross-sectional, population-based epidemiological study.
A total of 2046 adult Greenlanders (Inuit), 61% of those invited to participate, living in three areas of Greenland and in Denmark.
Height, weight, waist and hip circumferences were measured and body mass index (BMI in kg/m(2)) and waist-hip ratio calculated. Sociocultural information was obtained by questionnaire and interview. Westernization was estimated by language and place of residence.
The prevalence of obesity (>or=30 kg/m(2)) was 16 and 22% among men and women in Greenland (P=0.004), and 12 and 11%, respectively, in Denmark (NS). Westernization was accompanied by a decrease in the proportion of obese people, in particular among women. Adjusted for BMI, age and Inuit heritage waist circumference decreased with Westernization (among women), while hip circumference did not change. The differences were particularly pronounced for migrants compared with residents of Greenland.
BMI and central fat patterning decrease with Westernization among Greenland Inuit women contrary to most studies of migrants. The changes were less prominent among men. This suggests a reduced cardiovascular risk profile with Westernization among Greenland Inuit.
分析格陵兰因纽特人以及丹麦的因纽特移民中的超重、肥胖和中心性脂肪分布情况，及其与西方化的关系。
基于人群的横断面流行病学研究。
共有2046名成年格陵兰人（因纽特人），占受邀参与研究人数的61%，他们生活在格陵兰的三个地区以及丹麦。
测量身高、体重、腰围和臀围，计算体重指数（BMI，单位为kg/m²）和腰臀比。通过问卷调查和访谈获取社会文化信息。根据语言和居住地评估西方化程度。
格陵兰男性和女性的肥胖患病率（≥30 kg/m²）分别为16%和22%（P = 0.004），丹麦的患病率分别为12%和11%（无显著差异）。西方化伴随着肥胖人群比例的下降，尤其是在女性中。在调整了BMI、年龄和因纽特人血统后，腰围随着西方化程度的提高而减小（女性中），而臀围没有变化。与格陵兰居民相比，移民中的差异尤为明显。
与大多数移民研究相反，格陵兰因纽特女性的BMI和中心性脂肪分布随着西方化程度的提高而降低。男性中的变化不太明显。这表明格陵兰因纽特人随着西方化程度的提高，心血管疾病风险有所降低。
