Objectives. We estimated age-standardized ratios of infection and hospitalization among Canadian First Nations (FN) populations and compared their distributions with those estimated for non-FN populations in Manitoba, Canada. Methods. For the spring and fall 2009 waves of the H1N1 pandemic, we obtained daily numbers of laboratory-confirmed and hospitalized cases of H1N1 infection, stratified by 5-year age groups and FN status. We calculated agestandardized ratios with confidence intervals for each wave and compared ratios between age groups in each ethnic group and between the 2 waves for FN and non-FN populations. Results. Incidence and hospitalization ratios in all FN age groups during the first wave were significantly higher than those in non-FN age groups (P adolescent; adult; age distribution; aged; American Indian; article; Canada; child; comparative study; epidemiological monitoring; ethnology; hospitalization; human; incidence; infant; influenza; Influenza virus A H1N1; middle aged; newborn; pandemic; preschool child; statistics, Adolescent; Adult; Age Distribution; Aged; Child; Child, Preschool; Epidemiological Monitoring; Hospitalization; Humans; Incidence; Indians, North American; Infant; Infant, Newborn; Influenza A Virus, H1N1 Subtype; Influenza, Human; Manitoba; Middle Aged; Pandemics; Young Adult
