Table 1 shows baseline information for the study population
in 2010. Of the 11,004 eligible addresses in the
study areas to which surveys were sent, responses were
obtained from 4624 (42%) households comprising 8208
males and females aged 18 years or older who lived on

individuals indicated ethnic background as First Nations,

with a self-described Caucasian heritage. Table 1 also
shows distribution of study participants and crude diabetes
prevalence by geographic location and farm/nonfarm
residence. Although overall unadjusted diabetes
prevalence was similar between Saskatchewan0

zones, it ranged from 8.0% (lowest) in the northwest
quadrant to 10.4% (highest) in the northeast quadrant and,
in each quadrant, was significantly higher among non-farm
compared to farm residents. Overall, 10.7% of non-farm
residents and 6.9% of farm residents reported a physiciandiagnosis
