Abstract
The purpose of this study was to explore associations between early-life factors and the development of youth onset type 2 diabetes mellitus (T2DM). Until 1990, T2DM was seldom reported in youth, however rates of youth onset T2DM are rising worldwide. This retrospective case-control study utilized repository data housed at the Manitoba Centre for Health Policy to review perinatal exposures of Manitoba youth with and without T2DM. The mean age at time of diagnosis was 13.1 years and 61% of youth onset T2DM cases were female. The majority of youth with T2DM resided in rural areas at time of diagnosis. This study found a 14-fold increase in the risk of youth onset T2DM when the mother had pre-gestational diabetes, and 6.5-fold increase in that risk if the mother had gestational diabetes. Breastfeeding was found to be protective, and a lower income quintile at time of birth was found to be more significantly associated with the development of youth onset T2DM than increasingly higher income quintiles . The findings emphasize that efforts aimed at preventing T2DM in youth must begin in the pre-conception period and continue throughout pregnancy.
