Patterns of prescription opioid dispensing among Red River Métis in Manitoba, Canada: a retrospective longitudinal cross-sectional study.

Background: Amid rising concern about opioid use across Canada, Métis leaders in Manitoba are seeking information on prescription opioid dispensing in Red River Métis populations to assist with planning and implementing appropriate evidence-based harm-reduction strategies in their communities. We examined patterns of prescription opioid dispensing among Red River Métis and compared them to those among other residents of Manitoba.

Methods: We conducted a population-based retrospective cross-sectional study for fiscal years 2006/07-2018/19 using administrative data from the Manitoba Population Research Data Repository and a study designed in partnership with researchers from the Manitoba Métis Federation.

Use of Medication to Treat Attention-Deficit/Hyperactivity Disorder in Young Children: The Role of Maternal History of Psychotropic Medication Use.

We examine whether, among children diagnosed with ADHD, are those whose mothers have a history of psychotropic medication use more likely to treat their ADHD with medication? Children born in Manitoba, Canada from 2000 to 2010 diagnosed with ADHD between their 4th and 8th birthday. Maternal psychotropic medication use was assessed from one year before the child's birth to the child's fourth birthday. Logistic regression models examine the relationship between maternal history of psychotropic medication use and the use of medication to treat ADHD in children.
