Type 2 diabetes mellitus is increasingly being observed among children and youth, including the Native population of Canada. Only one study has investigated prenatal and early infancy risk factors for the disease.
A case-control study was conducted; 46 patients younger than 18 years were recruited from the only clinical center for the treatment of diabetes serving the province of Manitoba, and 92 age- and sex-matched controls were recruited from a pediatric ambulatory clinic serving a large Native population in Winnipeg, Manitoba. Information on exposure to prenatal and early infancy risk factors was obtained through questionnaires administered by a Native nurse-interviewer.
Multiple logistic regression modeling identified preexisting diabetes (odds ratio [OR], 14.4; 95% confidence interval [CI], 2.86-72.5), gestational diabetes (OR, 4.40; 95% CI, 1.38-14.1), and breastfeeding longer than 12 months (OR, 0.24; 95% CI, 0.13-0.99) as significant independent predictors of diabetic status. Other factors, such as low (<2500 g) and high (>4000 g) birth weight and maternal obesity, were also associated with diabetes in our population, but the elevated risks were not statistically significant.
Breastfeeding reduces the risk of type 2 diabetes among Native Canadian children and should be promoted as a potential intervention to control the disease.
