To compare two circumpolar populations at different stages in adoption of a modern lifestyle with respect to body fat content, fat distribution, blood lipids and blood pressures.
Cross-sectional comparison between Inuit and nGanasan.
141 male and 107 female Inuit (aged 17-49 years) living in the modern settlement of Igloolik (69 degrees 40'N, 81 degrees W) and 38 male and 39 female nGanasan living a more traditional lifestyle in Volochanka (71 degrees N, 94 degrees E).
Triceps, subscapular and suprailiac skinfold thicknesses, chest and waist circumferences, blood pressures, plasma total cholesterol, plasma HDL-cholesterol and triglyceride concentrations.
Igloolik Inuit now have similar subcutaneous fat readings to their urban counterparts, average values increasing with age from 10 to 16 mm in males, and from 15 to 29 mm in females. In Volochanka, the men retain low readings (6-8 mm), but the women (13-25 mm) almost match their Inuit counterparts. Individual skinfolds, chest and waist circumferences all show substantial correlations with blood pressure (nGanasan > Inuit). The subscapular/triceps ratio is also high (Igloolik, 1.55 to 1.74 in men, 1.06 to 1.15 in women; Volochanka, 1.45 to 1.70 in men and 1.20 to 1.70 in women), but this ratio is only weakly correlated with plasma lipids and blood pressures.
Internal fat deposition may reduce correlations between skinfolds and other cardiac risk factors. Nevertheless, the Inuit have accumulated fat in adopting a modern, sedentary lifestyle, with adverse implications for their future health.
比较处于现代生活方式采用不同阶段的两个极地人群在体脂含量、脂肪分布、血脂和血压方面的情况。
因纽特人和恩加纳桑人的横断面比较。
居住在伊格卢利克现代定居点（北纬69度40分，西经81度）的141名男性和107名女性因纽特人（年龄17 - 49岁），以及生活在沃洛昌卡（北纬71度，东经94度）、保持更传统生活方式的38名男性和39名女性恩加纳桑人。
肱三头肌、肩胛下和髂上皮肤褶厚度、胸围和腰围、血压、血浆总胆固醇、血浆高密度脂蛋白胆固醇和甘油三酯浓度。
伊格卢利克因纽特人的皮下脂肪读数现在与城市同龄人相似，男性平均值随年龄从10毫米增加到16毫米，女性从15毫米增加到29毫米。在沃洛昌卡，男性读数较低（6 - 8毫米），但女性（13 - 25毫米）几乎与因纽特女性相当。各个皮肤褶、胸围和腰围均与血压显著相关（恩加纳桑人>因纽特人）。肩胛下/肱三头肌比值也较高（伊格卢利克，男性为1.55至1.74，女性为1.06至1.15；沃洛昌卡，男性为1.45至1.70，女性为1.20至1.70），但该比值与血脂和血压的相关性较弱。
内脏脂肪沉积可能会降低皮肤褶与其他心脏危险因素之间的相关性。尽管如此，因纽特人在采用现代久坐生活方式过程中积累了脂肪，这对他们未来的健康有不利影响。
