Di erences in glycemic control and survival predict higher ESRD rates in diabetic rst nations adults Abstract Purpose: Diabetic First Nations people (FN) have higher ESRD rates than other Canadians but the reasons remain unclear. We sought to better understand this disparity by comparing demographic, laboratory and survival features of diabetic FN and other Saskatchewan residents (OSK) by renal function stage.Methods: Prevalent diabetes cases in 2005/06 were identi ed in Saskatchewan's two largest health regions using administrative databases, and linked with centralized laboratory tests. ey were sub-divided into ve stages of renal function using estimated glomerular ltration rates (eGFR) that were determined in 992 of 2,321 FN (42.7%) and 14,054 of 21,886 OSK (64.2%). Age, sex, urine microalbumin (MA), glycosylated hemoglobin (A1C), low density lipoprotein cholesterol (LDL-C) and two year mortality risk was compared for all subjects.Results: Diabetic FN were younger (mean age 52.7 vs. 64.2, p<0.0001), more likely to be female (59.6% vs.45.4%, p<0.001), had increased MA (56.6% vs. 48.4%, p<0.0001) and displayed higher mean A1C levels (8.16% vs.7.36%, p<0.0001) than OSK. Despite a larger proportion having eGFR's >60 ml/min (87.0% vs.77.3%, p<0.001), FN were also more likely to have ESRD (2.3% vs.0.8%, p<0.001). Although FN with eGFR's >30 ml/min experienced higher age/sex adjusted mortality risk than OSK, the trends for both adjusted and unadjusted mortality risks for those with advanced pre-ESRD renal failure were lower for FN than for OSK.Conclusions: Elevated rates of ESRD experienced by FN with diabetes are related to poorer glycemic control at all levels of renal function, and lower age-related mortality at advanced stages of chronic kidney disease. ORIGINAL RESEARCH © 2010 CIMClin In E390 Diabetes mellitus is the most common cause of end stage renal disease (ESRD) in Canada [1] but the burden of diabetic ESRD upon indigenous peoples is of particular concern. In 1994, a disproportionate incidence of ESRD was reported among Saskatchewan First Nations (FN) people with diabetes [2] and a recent study shows that such disparities persist [3]. While the mechanisms underlying these observations are incompletely understood, there are two possibilities. First, FN with diabetes may be more prone to the initial development of diabetic glomerulosclerosis, which can lead to ESRD. is is supported by reports that diabetic FN have higher rates of microalbuminuria [4]. Second, FN with early diabetic glomerulosclerosis may progress to ESRD more frequently than others because of a more rapid course and/or lower mortality rates. Although our recent ndings that FN are diagnosed at a a younger age and experience a longer duration between diabetes and ESRD diagnoses are consistent with a di erential mortality e ect [5] other studies report lower survival rates among FN with all-cause advanced chronic kidney disease (CKD) [6].Identifying the mechanisms underlying ethnicity-based di erences in diabetic ESRD is important for understa...

“…For diabetes prevalence calculations, we included all Ministry of Health beneficiaries in the denominator. 10,14 To calculate diabetes incidence, we first subtracted prevalent diabetes cases. Age-standardized rate calculations used the direct method standardized to the 1991 Canadian census population.…”

“…Nearly all (99%) Saskatchewan residents receive provincial healthcare coverage (Downey et al, 2005) and constitute the "covered population" for the present study. Federally insured residents (federal prison inmates, members of the Canadian Forces, and Royal Canadian Mounted Police) are not included in the covered population (Saskatchewan Ministry of Health, 2012); however, their information is captured in hospital data.…”

Background:Original studies published over the last decade regarding time trends in dementia report mixed results. The aims of the present study were to use linked administrative health data for the province of Saskatchewan for the period 2005/2006 to 2012/2013 to: (1) examine simultaneous temporal trends in annual age-and sex-specific dementia incidence and prevalence among individuals aged 45 and older, and (2) stratify the changes in incidence over time by database of identification.
