Abstract
Background. Influenza infection during pregnancy is associated with adverse fetal outcomes such as preterm birth and small for gestational age (SGA). Maternal influenza immunization may prevent these adverse infant outcomes during periods of influenza circulation. Methods. We conducted a retrospective cohort study of live births within Kaiser Permanente (KP) Georgia and Mid-Atlantic States (n = 3327) during the period of 2009 influenza A (H1N1) virus circulation. Primary outcomes were third-trimester preterm birth (27-36 weeks), birth weight, low birth weight (LBW, <2500 g), and SGA. Results. There were 327 (9.8%) preterm, 236 (7.4%) LBW, and 267 (8.4%) SGA births. Among H1N1-vaccinated mothers (n = 1125), there were 86 (7.6%) preterm, 68 (6.4%) LBW, and 99 (9.3%) SGA births, and the mean birth weight was 3308.5 g (95% confidence interval [CI], 3276.6-3340.4). Among unvaccinated mothers (n = 1581), there were 191 (12.1%) preterm, 132 (8.8%) LBW, and 123 (8.2%) SGA births, and the mean birth weight was 3245.3 g (95% CI, 3216.5-3274.2). Infants of H1N1-vaccinated mothers had 37% lower odds of being born preterm than infants of unvaccinated mothers (adjusted odds ratio, 0.63 [95% CI, .47-.84]). The mean birth weight difference between infants of H1N1-vaccinated mothers and infants of unvaccinated mothers was 45.1 g (95% CI, 1.8-88.3). There was no significant association between maternal H1N1 influenza immunization and LBW or SGA. Conclusions. Pregnant women who received H1N1 influenza vaccine were less likely to give birth preterm, and gave birth to heavier infants. The findings support US vaccine policy choices to prioritize pregnant women during the 2009 influenza A (H1N1) pandemic.

There were 327 (9.8%) preterm, 236 (7.4%) LBW, and 267 (8.4%) SGA births. Among H1N1-vaccinated mothers (n = 1125), there were 86 (7.6%) preterm, 68 (6.4%) LBW, and 99 (9.3%) SGA births, and the mean birth weight was 3308.5 g (95% confidence interval [CI], 3276.6-3340.4). Among unvaccinated mothers (n = 1581), there were 191 (12.1%) preterm, 132 (8.8%) LBW, and 123 (8.2%) SGA births, and the mean birth weight was 3245.3 g (95% CI, 3216.5-3274.2). Infants of H1N1-vaccinated mothers had 37% lower odds of being born preterm than infants of unvaccinated mothers (adjusted odds ratio, 0.63 [95% CI, .47-.84]). The mean birth weight difference between infants of H1N1-vaccinated mothers and infants of unvaccinated mothers was 45.1 g (95% CI, 1.8-88.3). There was no significant association between maternal H1N1 influenza immunization and LBW or SGA. Conclusions. Pregnant women who received H1N1 influenza vaccine were less likely to give birth preterm, and gave birth to heavier infants. The findings support US vaccine policy choices to prioritize pregnant women during the 2009 influenza A (H1N1) pandemic.</div></front></TEI><inist><standard h6="B"><pA><fA01 i1="01" i2="1"><s0>1058-4838</s0></fA01><fA02 i1="01"><s0>CIDIEL</s0></fA02><fA03 i2="1"><s0>Clin. infect. dis.</s0></fA03><fA05><s2>56</s2></fA05><fA06><s2>9</s2></fA06><fA08 i1="01" i2="1" l="ENG"><s1>Neonatal Outcomes After Antenatal Influenza Immunization During the 2009 H1N1 Influenza Pandemic: Impact on Preterm Birth, Birth Weight, and Small for Gestational Age Birth</s1></fA08><fA11 i1="01" i2="1"><s1>RICHARDS (Jennifer L.)</s1></fA11><fA11 i1="02" i2="1"><s1>HANSEN (Craig)</s1></fA11><fA11 i1="03" i2="1"><s1>BREDFELDT (Christine)</s1></fA11><fA11 i1="04" i2="1"><s1>BEDNARCZYK (Robert A.)</s1></fA11><fA11 i1="05" i2="1"><s1>STEINHOFF (Mark C.)</s1></fA11><fA11 i1="06" i2="1"><s1>ADJAYE-GBEWONYO (Dzifa)</s1></fA11><fA11 i1="07" i2="1"><s1>AULT (Kevin)</s1></fA11><fA11 i1="08" i2="1"><s1>GALLAGHER (Mia)</s1></fA11><fA11 i1="09" i2="1"><s1>ORENSTEIN (Walter)</s1></fA11><fA11 i1="10" i2="1"><s1>DAVIS (Robert L.)</s1></fA11><fA11 i1="11" i2="1"><s1>OMER (Saad B.)</s1></fA11><fA14 i1="01"><s1>Center for Health Research-Southeast, Kaiser Permanente</s1><s3>USA</s3><sZ>1 aut.</sZ><sZ>2 aut.</sZ><sZ>4 aut.</sZ><sZ>6 aut.</sZ><sZ>8 aut.</sZ><sZ>9 aut.</sZ><sZ>10 aut.</sZ><sZ>11 aut.</sZ></fA14><fA14 i1="02"><s1>Rollins School of Public Health, Emory University</s1><s2>Atlanta, Georgia</s2><s3>USA</s3><sZ>1 aut.</sZ><sZ>4 aut.</sZ><sZ>7 aut.</sZ><sZ>11 aut.</sZ></fA14><fA14 i1="03"><s1>Mid-Atlantic Permanente Research Institute, Kaiser Permanente Mid-Atlantic States</s1><s2>Rockville, Maryland</s2><s3>USA</s3><sZ>3 aut.</sZ></fA14><fA14 i1="04"><s1>Cincinnati Children's Hospital Medical Center</s1><s2>Cincinnati, Ohio</s2><s3>USA</s3><sZ>5 aut.</sZ></fA14><fA14 i1="05"><s1>Bloomberg School of Public Health, Johns Hopkins University</s1><s2>Baltimore, Maryland</s2><s3>USA</s3><sZ>5 aut.</sZ></fA14><fA14 i1="06"><s1>School of Medicine, Emory University</s1><s2>Atlanta, Georgia</s2><s3>USA</s3><sZ>7 aut.</sZ><sZ>11 aut.</sZ></fA14><fA14 i1="07"><s1>Emory Vaccine Center, Emory University</s1><s2>Atlanta, Georgia</s2><s3>USA</s3><sZ>7 aut.</sZ><sZ>9 aut.</sZ><sZ>11 aut.</sZ></fA14><fA20><s1>1216-1222</s1></fA20><fA21><s1>2013</s1></fA21><fA23 i1="01"><s0>ENG</s0></fA23><fA43 i1="01"><s1>INIST</s1><s2>18407</s2><s5>354000500660760040</s5></fA43><fA44><s0>0000</s0><s1>© 2013 INIST-CNRS.

Influenza infection during pregnancy is associated with adverse fetal outcomes such as preterm birth and small for gestational age (SGA). Maternal influenza immunization may prevent these adverse infant outcomes during periods of influenza circulation. Methods. We conducted a retrospective cohort study of live births within Kaiser Permanente (KP) Georgia and Mid-Atlantic States (n = 3327) during the period of 2009 influenza A (H1N1) virus circulation. Primary outcomes were third-trimester preterm birth (27-36 weeks), birth weight, low birth weight (LBW, <2500 g), and SGA. Results. There were 327 (9.8%) preterm, 236 (7.4%) LBW, and 267 (8.4%) SGA births. Among H1N1-vaccinated mothers (n = 1125), there were 86 (7.6%) preterm, 68 (6.4%) LBW, and 99 (9.3%) SGA births, and the mean birth weight was 3308.5 g (95% confidence interval [CI], 3276.6-3340.4). Among unvaccinated mothers (n = 1581), there were 191 (12.1%) preterm, 132 (8.8%) LBW, and 123 (8.2%) SGA births, and the mean birth weight was 3245.3 g (95% CI, 3216.5-3274.2). Infants of H1N1-vaccinated mothers had 37% lower odds of being born preterm than infants of unvaccinated mothers (adjusted odds ratio, 0.63 [95% CI, .47-.84]). The mean birth weight difference between infants of H1N1-vaccinated mothers and infants of unvaccinated mothers was 45.1 g (95% CI, 1.8-88.3). There was no significant association between maternal H1N1 influenza immunization and LBW or SGA. Conclusions. Pregnant women who received H1N1 influenza vaccine were less likely to give birth preterm, and gave birth to heavier infants.
