Abstract
<?Pub Inc> In the James Bay Cree of Canada a nutrition transition has contributed to an increased prevalence of obesity and chronic diseases. A cross-sectional survey was conducted in five Iiyiyiu Aschii (Cree) communities. Dietary characteristics and physical activity levels were evaluated for their association with adiposity and insulin resistance in James Bay Cree adults (n = 486). The current analyses were restricted to those 18 years of age and older without a pre-existing diagnosis of diabetes mellitus. Diet quality, physical activity levels, and other characteristics were evaluated for their associations with obesity, impaired fasting glucose (IFG), and insulin resistance. The results revealed that regular walking (>= 6 days/week) was inversely associated to adiposity measures and HOMA-IR (Homeostasis Model Assessment of Insulin Resistance). In addition, the consumption of high-sugar drinks was associated with having an at-risk body mass index (BMI) and increased odds ratio (OR) for having an IFG in analyses adjusted for age, sex, and regular walking. The results indicate that promotion of daily walking and cessation of high-sugar drinks may help mitigate nutrition and epidemiologic transition in Cree communities.
