There may be complex associations between family support and the circumstances of a pregnancy during adolescence. The aim of the study was to analyze the association between the family support network (FSN) characteristic and the maternal and neonatal outcomes in Mexican adolescents. A cross-sectional study was conducted, and 352 pregnant adolescents participated; their FSN during pregnancy was assessed. The gestational weight gain and birth weight\/length of newborns were registered. The size of the FSN was described and divided into quartiles; the main members for each quartile were identified. Then, sociodemographic and clinical variables were compared by FSN quartiles. Logistic regression models were performed to assess the association of FSN size and pregnancy and neonatal outcomes. Our results indicate that the mean age was 15 \u00b1 1 year old. The primary support member in the FSN was the mother of the adolescent in each quartile, except for quartile 3, where the primary support was the mother-in-law. In quartile 3 there was a significantly lower gestational weight gain compared to quartile 4 (11.8 \u00b1 5 vs. 13 \u00b1 5 kg, p = 0.054). According to the regression model, a higher risk of small for gestational age (OR 2.99, CI 95% 1.25\u20137.15) newborns was found in quartile 3. We conclude that the maternal and neonatal outcomes did not differ between quartiles of FSN size, except for quartile 3. Small for gestational age newborns were observed when a non-blood relative was present in the FSN. The quality rather than the network size might be more important for improving pregnancy outcomes.<\/jats:p>","DOI":"10.3390\/ijerph16071222","type":"journal-article","created":{"date-parts":[[2019,4,5]],"date-time":"2019-04-05T11:36:01Z","timestamp":1554464161000},"page":"1222","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Characteristics of the Family Support Network of Pregnant Adolescents and Its Association with Gestational Weight Gain and Birth Weight of Newborns"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5490-1363","authenticated-orcid":false,"given":"Reyna","family":"S\u00e1mano","sequence":"first","affiliation":[{"name":"Departamento de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud Montes Urales 800, Miguel Hidalgo, Lomas Virreyes, Ciudad de Mexico CP. 11000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5301-9878","authenticated-orcid":false,"given":"Hugo","family":"Mart\u00ednez-Rojano","sequence":"additional","affiliation":[{"name":"Departamento de Posgrado e Investigaci\u00f3n, Escuela Superior de Medicina del Instituto Polit\u00e9cnico Nacional, Plan de San Luis y D\u00edaz Mir\u00f3n s\/n, Colonia Casco de Santo Tomas, Delegaci\u00f3n Miguel Hidalgo, Ciudad de Mexico CP. 11340, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5741-0241","authenticated-orcid":false,"given":"Gabriela","family":"Chico-Barba","sequence":"additional","affiliation":[{"name":"Departamento de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud Montes Urales 800, Miguel Hidalgo, Lomas Virreyes, Ciudad de Mexico CP. 11000, Mexico"},{"name":"Escuela de Enfermer\u00eda, Universidad Panamericana, Augusto Rodin 498, Insurgentes Mixcoac, Alcald\u00eda Benito Ju\u00e1rez CP. 03920, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernarda","family":"S\u00e1nchez-Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"Subdirecci\u00f3n de Investigaci\u00f3n en Intervenciones Comunitarias, Instituto Nacional de Perinatolog\u00eda, Montes Urales 800, Lomas Virreyes, Alcald\u00eda Miguel Hidalgo CP. 11000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7654-9081","authenticated-orcid":false,"given":"Daniel","family":"Illescas-Zarate","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Nutrici\u00f3n y Salud (CINyS) del Instituto Nacional de Salud P\u00fablica.
