A survey of 704 adult Cree and Ojibwa Indians in northern Canada found that a large proportion of individuals in all age-sex groups was obese. Almost 90% of females aged 45-54 y had a body mass index (BMI) greater than or equal to 26. The obesity was primarily of the central type as gauged by skinfold thickness and girth ratios. Multivariate analyses showed that age, sex, smoking, alcohol use, marital status, and employment were associated with the levels of BMI and/or the sum of skinfold thicknesses. When three categories of BMI were compared, higher age-adjusted mean serum lipids, blood pressures, glucose, and glycosylated hemoglobin were observed in the obese subjects whereas total energy was decreased. Calorie-adjusted carbohydrate intake was higher in the obese subjects. BMI was an independent and significant predictor of both diabetic and hypertensive status. Obesity is a significant public health problem for Indians and poses particular risks for future chronic diseases.
对加拿大北部704名成年克里族和奥吉布瓦族印第安人的一项调查发现，所有年龄性别组中很大一部分人都肥胖。几乎90%的45 - 54岁女性体重指数（BMI）大于或等于26。根据皮褶厚度和周长比判断，肥胖主要为中心型。多变量分析表明，年龄、性别、吸烟、饮酒、婚姻状况和就业与BMI水平和/或皮褶厚度总和有关。当比较三类BMI时，肥胖受试者的年龄调整后平均血脂、血压、血糖和糖化血红蛋白较高，而总能量降低。肥胖受试者经热量调整后的碳水化合物摄入量较高。BMI是糖尿病和高血压状态的独立且显著的预测指标。肥胖是印第安人的一个重大公共卫生问题，对未来的慢性病构成特别风险。
