OBJECTIVE In vitro evidence shows that immune function is compromised in people with diabetes. Although certain rare infections are more common and infection-related mortality is higher, the risk of acquiring an infectious disease for diabetic patients has never been quantified. RESEARCH DESIGN AND METHODS A retrospective cohort study using administrative(More)
OBJECTIVE The definition of obesity (BMI ≥ 30 kg/m(2)), a key risk factor of diabetes, is widely used in white populations; however, its appropriateness in nonwhite populations has been questioned. We compared the incidence rates of diabetes across white, South Asian, Chinese, and black populations and identified equivalent ethnic-specific BMI cutoff values(More)
BACKGROUND Women with preeclampsia (PEC) and gestational hypertension (GH) exhibit insulin resistance during pregnancy, independent of obesity and glucose intolerance. Our aim was to determine whether women with PEC or GH during pregnancy have an increased risk of developing diabetes after pregnancy, and whether the presence of PEC/GH in addition to(More)
OBJECTIVE To examine the risk of new onset diabetes among patients treated with different HMG-CoA reductase inhibitors (statins). DESIGN Population based cohort study with time to event analyses to estimate the relation between use of particular statins and incident diabetes. Hazard ratios were calculated to determine the effect of dose and type of statin(More)
OBJECTIVE To determine whether women with gestational diabetes mellitus (GDM) have an increased risk of cardiovascular disease (CVD) following pregnancy. RESEARCH DESIGN AND METHODS All women aged 20-49 years with live births between April 1994 and March 1997 in Ontario, Canada, were identified. Women with GDM were matched with 10 women without GDM and(More)
OBJECTIVE To determine in Canadian children aged <18 years the 1) incidence of type 2 diabetes, medication-induced diabetes, and monogenic diabetes; 2) clinical features of type 2 diabetes; and 3) coexisting morbidity associated with type 2 diabetes at diagnosis. RESEARCH DESIGN AND METHODS This Canadian prospective national surveillance study involved a(More)
BACKGROUND Gatifloxacin has been associated with both hypoglycemia and hyperglycemia. We examined dysglycemia-related health outcomes associated with various antibiotics in a population of approximately 1.4 million Ontario, Canada, residents 66 years of age or older. METHODS We conducted two population-based, nested case-control studies. In the first,(More)
OBJECTIVE To determine whether adjusting for confounder bias in observational studies using propensity scores gives different results than using traditional regression modeling. METHODS Medline and Embase were used to identify studies that described at least one association between an exposure and an outcome using both traditional regression and(More)
AIMS To compare the prevalence of diabetes in pregnancy, pregnancy care and adverse pregnancy outcomes in on-reserve First Nations women vs. non-First Nations women in Ontario, Canada. METHODS A retrospective population-based cohort study was performed. All 487368 live singleton hospital deliveries between 1 April 2002 and 31 March 2010 were identified.(More)
BACKGROUND Evidence from large, population-based studies about the association between neighbourhood walkability and the prevalence of obesity is limited. DATA AND METHODS The study population consisted of 106,337 people aged 20 or older living in urban and suburban Ontario, who participated in the National Population Health Survey and the Canadian(More)
