Objectives: To determine the prevalence of diabetes (using secondary data analysis), as well as undiagnosed diabetes and pre-diabetes (using primary research methods) among adult Métis Settlement dwellers in northern Alberta. We also sought to identify cardiovascular risk factors., Study Design: Quantitative research study utilizing both population census and community-based diabetes screening data., Methods: Self-reported diabetes was analyzed from the results of the Métis Settlement specific censuses in 1998 and 2006. Mobile clinics travelled into each of the 8 Métis Settlement communities in Alberta recruiting 693 subjects for screening for undiagnosed diabetes, pre-diabetes and metabolic syndrome. Logistic regression analyses (adjusted for age and sex) were used to identify associated factors., Results: According to the censuses, 4,312 Métis individuals were living on Settlements in 1998 and 5,059 in 2006. Self-reported age-adjusted prevalence of diabetes increased significantly from 5.1% in 1998 to 6.9% in 2006 (p < 0.01), with a crude prevalence increase of 66% (p < 0.01). In 2006, diabetes prevalence was higher among females than males, 7.8% vs. 6.1% respectively (p < 0.05). Of the 266 adults screened in the fasting state, 5.3% had undiagnosed diabetes, whereas 20.3% (Canadian Diabetes Association criteria) and 51.9% (American Diabetes Association criteria) had pre-diabetes. Rates of obesity and metabolic syndrome were 49.4% (n = 693) and 46.4% (n = 266), respectively. Hemoglobin A1c > 6.1% was strongly associated with diabetes, pre-diabetes and metabolic syndrome., Conclusions: Our results indicate high rates of diabetes, undiagnosed diabetes, pre-diabetes and metabolic syndrome among adult Alberta Métis Settlement dwellers.
