Children with transient and persistent/late wheeze were compared to children who had never wheezed. Unadjusted and adjusted analyses for each maternal variable are presented. RR: relative risk; ALA: alpha-linolenic acid; DHA: docosahexaenoic acid; EPA: eicosapentaenoic acid; LA: linoleic acid; AA: arachidonic acid. RR derived from Poisson regression.
*Adjusted for maternal asthma and rhinitis, parity, child’s sex, and maternal educational attainment. †Adjusted for maternal asthma and rhinitis, paternal asthma, maternal smoking in pregnancy, child’s sex, and maternal educational attainment.
