Overweight and obesity among Alaskan Eskimos of the Bering Straits Region: the Alaska Siberia project.
OBJECTIVE
To document the height, weight, BMI and prevalence of obesity for Eskimo residents of four villages of the Bering Straits Region of Alaska.


METHODS
454 Non-pregnant residents over 24 y of age, with at least one Eskimo grandparent participated in one cross sectional survey within each village.


METHODS
Height, weight, calculation of BMI (kg/m2), proportion of 'overweight' (BMI 25-29.9), and proportion of 'obese' (BMI>/=30).


RESULTS
For women and men, respectively, mean heights were 153.4 and 165.2 cm; weights were 64.2 and 71.6 kg; and BMI were 27.2 and 26.2 kg/m2 after age standardization. For women, 27.9% were overweight, and 32.8% were obese compared with 36.2% and 15.6%, respectively, for men. Alaskan Eskimo participants of the Alaska Siberia Project had a significantly lower proportion of total overweight (BMI>/=25, 54.9% for women, and 32.0% for men) compared with the three sites of the Strong Heart Study, which ranged from 65.9 to 80.2% for women and 53.6 to 66.7% for men. Compared with American men of all races, the proportion of overweight and obese participants was similar for Eskimo men. The proportion of obese was significantly higher for Eskimo women compared with American women of all races, but the proportion of overweight was similar.


CONCLUSIONS
Although the prevalence of obesity among the Alaskan Eskimos is lower than for American Indians, the high proportion of overweight observed in this study is of concern for Alaskan Eskimo adults, especially for women.
