To estimate the prevalence of general (body mass index) and central (waist circumference and waist/hip ratio) obesity in an area with a mixed Sami and Norwegian population.
A cross-sectional population-based study carried out in 2003- 2004, the SAMINOR study. The attendance rate was 60.6%. A total of 7,301 men and 7,841 women, aged 36-79, were included in the analyses. Height, weight, waist and hip circumference were measured, body mass index (BMI) calculated and information concerning lifestyle was collected by questionnaire.
The prevalence of general obesity (BMI > or = 30 kg/m(2)) in participants who had Sami as their home language for three generations (Sami I) and Norwegian participants was 38.7% and 24.3% for women respectively; and for men 26.9% and 23.4% respectively. More than 40% of the women had central obesity (waist circumference > or = 88 cm), and the highest prevalence was found in Sami I women (45%). The highest prevalence of central obesity (waist circumference > or = 102 cm) was found in Norwegian men (24.2%). The ethnic differences persisted after adjustment for age, education, physical activity in leisure time, and smoking habits.
The prevalence of obesity was high in this population and central obesity was most pronounced in women, particularly in Sami women. Sami men were less obese than Norwegian men. Further studies are necessary to examine a possible explanation for these findings, especially to elaborate on the impact of diet.
评估一个拥有混合萨米族和挪威人群的地区中普遍（身体质量指数）和中心（腰围和腰臀比）肥胖的流行情况。
这是一项于 2003-2004 年进行的横断面基于人群的研究，SAMINOR 研究。出席率为 60.6%。共纳入 7301 名男性和 7841 名年龄在 36-79 岁之间的女性。通过问卷收集身高、体重、腰围和臀围数据，计算体重指数（BMI），并获取生活方式信息。
三代母语为萨米语的萨米人（萨米 I）和挪威参与者中普遍肥胖（BMI≥30kg/m²）的患病率分别为女性 38.7%和 24.3%；男性分别为 26.9%和 23.4%。超过 40%的女性患有中心性肥胖（腰围≥88cm），萨米 I 女性的患病率最高（45%）。腰围≥102cm 的中心性肥胖患病率最高见于挪威男性（24.2%）。在调整年龄、教育、休闲时间体力活动和吸烟习惯后，这些种族差异仍然存在。
该人群的肥胖患病率较高，中心性肥胖在女性中最为明显，尤其是萨米女性。萨米男性的肥胖程度低于挪威男性。需要进一步研究以探讨这些发现的可能解释，特别是要详细说明饮食的影响。
