Individual\u2010level differences in attained size and growth, when using WHO\u2010GS versus IG\u2010NS, were greater than 0.2 SD in magnitude for &gt;60% of infants across all anthropometric indices.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Using IG\u2010NS at birth with WHO\u2010GS postnatally is acceptable for full\u2010term infants but may give a misleading interpretation of growth trajectories among early\u2010 and late\u2010term infants.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ppe.12880","type":"journal-article","created":{"date-parts":[[2022,5,16]],"date-time":"2022-05-16T07:36:07Z","timestamp":1652686567000},"page":"839-850","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Implications for quantifying early life growth trajectories of term\u2010born infants using INTERGROWTH\u201021st newborn size standards at birth in conjunction with World Health Organization child growth standards in the postnatal period"],"prefix":"10.1111","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3624-4405","authenticated-orcid":false,"given":"Nandita","family":"Perumal","sequence":"first","affiliation":[{"name":"Department of Global Health and Population Harvard TH Chan School of Public Health  Boston Massachusetts USA"},{"name":"Centre for Global Child Health Peter Gilgan Centre for Research and Learning The Hospital for Sick Children  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric O.","family":"Ohuma","sequence":"additional","affiliation":[{"name":"Centre for Global Child Health Peter Gilgan Centre for Research and Learning The Hospital for Sick Children  Toronto Ontario Canada"},{"name":"Maternal, Adolescent, Reproductive and Child Health Centre, Department of Infectious Disease Epidemiology London School of Hygiene and Tropical Medicine  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew M.","family":"Prentice","sequence":"additional","affiliation":[{"name":"MRC Unit The Gambia at the London School of Hygiene and Tropical Medicine  Fajara The Gambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prakesh S.","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mount Sinai Hospital &amp;
