Negative binomial regression was used to estimate the incidence rate ratio (IRR) and 95% confidence intervals (CIs) at \u22641 year and \u22645 years for ED presentations and admissions to the hospital through the ED for any reason and by 9 major disease categories for children exposed versus children not exposed to maternal smoking during pregnancy. Models were adjusted for sex, socioeconomic position, maternal age at birth, and region of residence. Presentations and admissions for poisoning and injuries were used as a negative control.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>Among 36\u2009630 infants, 21% were exposed to maternal smoking during pregnancy.
