However, since the fourth health screening (30\u201380\u2009months after birth), the fraction of underweight was no longer different between children from influenza-infected and non-infected mothers, whereas the rates of overweight increased paradoxically in those born to mothers with influenza infection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Maternal influenza infection might have long-term effects on the health of children and adolescents even after infancy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12879-020-05236-8","type":"journal-article","created":{"date-parts":[[2020,7,11]],"date-time":"2020-07-11T01:02:48Z","timestamp":1594429368000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Paradoxical long-term impact of maternal influenza infection on neonates and infants"],"prefix":"10.1186","volume":"20","author":[{"given":"Joon Young","family":"Song","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keon Vin","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Won","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Joo","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Yun","family":"Noh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hee Jin","family":"Cheong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woo Joo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min-Jeong","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geum Joon","family":"Cho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,7,11]]},"reference":[{"issue":"6","key":"5236_CR1","doi-asserted-by":"publisher","first-page":"299","DOI":"10.1055\/s-2001-17861","volume":"18","author":"G Gaunt","year":"2001","unstructured":"Gaunt G, Ramin K.
