ABSTRACT
The aim of this study was to explore the relationship between insulin resistance (IR) and objectively measured habitual moderate-to-vigorous physical activity (MVPA) in First Nations youth. A cross-sectional study was conducted in 2 rural villages in northern British Columbia, Canada. Thirty-nine healthy youth (16 males and 23 females; age = 11.8 yrs +/- 2.2; range = 8.8-18.5 yrs) participated. PA was measured with ActiGraph GT1M accelerometers. The homeostasis model assessment estimate of IR (HOMA-IR) was used to define IR. Duration of MVPA was inversely related to HOMA-IR (r = -.44, p < .01). From the regression model, 30 min of habitual MVPA corresponded to HOMA-IR levels that were 15% lower. In conclusion, these findings suggest that active First Nations youth have lower HOMA-IR values.
