Anthropometry and body composition, estimated by air displacement plethysmography, were evaluated at the corrected ages: term and 1, 3, and 5 months. We used the lean mass\/fat mass index (LM\/FM) at each time point and the weight, length and head circumference SDS gain between the time points.<\/jats:p><\/jats:sec><jats:sec id=\"j_jpm-2017-0175_s_997_w2aab3b7c31b1b6b1aab1c15b3Aa\"><jats:title>Results:<\/jats:title><jats:p>At term age, the SGA preterm infants had less lean mass (g), fat mass (g) and percent fat mass but a greater LM\/FM index than AGA infants (P&lt;0.001). At 1 month corrected age the LM\/FM index and percent fat mass between the groups became similar. Lower lean mass persisted up to 3 months in the SGA group [4004 g (3256\u20134595) vs. 4432 g (3190\u20136246), P&lt;0.001]. During the first month corrected age, the weight SDS gain was higher in SGA preterm infants when compared to AGA preterm infants. However, the SGA preterm infants remained lighter, shorter and with smaller head circumferences than the AGA preterm infants until 3 months of corrected age.<\/jats:p><\/jats:sec><jats:sec id=\"j_jpm-2017-0175_s_996_w2aab3b7c31b1b6b1aab1c15b4Aa\"><jats:title>Conclusions:<\/jats:title><jats:p>The greater lean tissue deficits and an earlier \u201ccatch-up\u201d in fat in the SGA group can reflect growth patterns variability since the early life.<\/jats:p><\/jats:sec>","DOI":"10.1515\/jpm-2017-0175","type":"journal-article","created":{"date-parts":[[2018,2,6]],"date-time":"2018-02-06T10:01:38Z","timestamp":1517911298000},"page":"804-810","source":"Crossref","is-referenced-by-count":9,"title":["Body composition in preterm infants with intrauterine growth restriction: a cohort study"],"prefix":"10.1515","volume":"46","author":[{"given":"Let\u00edcia Duarte","family":"Villela","sequence":"first","affiliation":[{"name":"Departamento de Neonatologia , Instituto Fernandes Figueira, Funda\u00e7\u00e3o Oswaldo Cruz, FIOCRUZ , Avenida Rui Barbosa, 716.
