Premastication is hypothesized to have both positive and negative implications for children, but the net effect of premastication on child health and nutrition is largely unknown because of a lack of research. This study quantitatively describes premastication in 5 provinces of Laos and examines the associations between premastication and the length of young children. We analyzed cross\u2010sectional data from the Laos 2015 Food and Nutrition Security Survey to characterize premastication among children under 2\u00a0years of age (<jats:italic>n<\/jats:italic>\u00a0=\u00a01,661) and to test associations between premastication and child length\u2010for\u2010age <jats:italic>z<\/jats:italic>\u2010score. We explored associations using multilevel mixed effects linear regression. Among children 0\u201323\u00a0months, 27.2% of mothers reported giving premasticated food in the past week. Receipt of premasticated food was inversely associated with length\u2010for\u2010age <jats:italic>z<\/jats:italic>\u2010score after controlling for potential confounders (child's age, ethno\u2010linguistic group, wealth, and parity) among children 6\u201313\u00a0months (\u03b2 \u22120.36, CI [\u22120.68, \u22120.04]) and among children 14\u201323\u00a0months (\u03b2 \u22120.43, CI [\u22120.81, \u22120.05]). For breastfed children 0\u20135\u00a0months who received complementary food, the coefficient was similar, but the association was not statistically significant (\u03b2 \u22120.42, CI [\u22121.2, 0.37]). Premastication is a common feeding practice for children 0\u201323\u00a0months of age, and many infants consume premasticated food on a daily basis. There was a negative relationship between premastication and child length. However, given the cross\u2010sectional nature of this study and potential unmeasured confounding factors, reverse causality or confounding cannot be ruled out. Longitudinal studies are needed to develop recommendations on premastication.<\/jats:p>","DOI":"10.1111\/mcn.12456","type":"journal-article","created":{"date-parts":[[2017,4,27]],"date-time":"2017-04-27T22:05:38Z","timestamp":1493330738000},"source":"Crossref","is-referenced-by-count":5,"title":["Premastication and length for age among children under 24\u00a0months in Laos"],"prefix":"10.1111","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2603-5052","authenticated-orcid":false,"given":"Joel","family":"Conkle","sequence":"first","affiliation":[{"name":"Nutrition and Health Sciences Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sengchanh","family":"Kounnavong","sequence":"additional","affiliation":[{"name":"Division of Health System Research, National Institute of Public Health The Ministry of Health  Vientiane Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Young","sequence":"additional","affiliation":[{"name":"Hubert Department of Global Health Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aryeh D.","family":"Stein","sequence":"additional","affiliation":[{"name":"Hubert Department of Global Health Emory University  Atlanta Georgia USA"},{"name":"Department of Epidemiology, Rollins School of Public Health Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,4,27]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejcn.1602928"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)61690-0"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.109.2.210"},{"key":"e_1_2_8_5_1","volume-title":"Nutrient adequacy of exclusive breastfeeding for the term infant during the first six months of life","author":"Butte N.
