To generate the database, we used IMSS hospitals\u2019 records in the State of Chihuahua, covering the period between 1 January 2000 and 31 December 2004. We included singleton live births only, and excluded babies with congenital malformations. The birthweights of 88\u2003368 children born at 21\u201344 weeks of gestation comprised our data. From these data, we calculated the 10th, 50th and 90th percentiles for each sex, at 32\u201344 weeks of gestation. The observed cutoffs for the 10th percentile in our population were 40\u2013250\u2003g higher than those reported in other references with Mexican populations. These results constitute an updated birthweight reference that will allow the identification of newborns in the North region of the country with low birthweight\u2010for\u2010gestational age. Such information can be a useful instrument for preventing or diminishing associated risks.<\/jats:p>","DOI":"10.1111\/j.1365-3016.2007.00898.x","type":"journal-article","created":{"date-parts":[[2008,2,20]],"date-time":"2008-02-20T13:28:57Z","timestamp":1203514137000},"page":"188-194","source":"Crossref","is-referenced-by-count":13,"title":["Birthweight percentiles by gestational age and gender for children in the North of Mexico"],"prefix":"10.1111","volume":"22","author":[{"given":"Jes\u00fas Manuel","family":"R\u00edos","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edith","family":"Tufi\u00f1o\u2010Olivares","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Reza\u2010L\u00f3pez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luz Helena","family":"San\u00edn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margarita","family":"Levario\u2010Carrillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,2,20]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.111.6.1430"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(93)90681-8"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-200606000-00004"},{"key":"e_1_2_6_5_2","doi-asserted-by":"crossref","first-page":"707","DOI":"10.1542\/peds.86.5.707","article-title":"Impact of intrauterine growth retardation and body proportionality of fetal and neonatal outcome","volume":"86","author":"Kramer MS","year":"1990","journal-title":"Pediatrics"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(97)70316-0"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.108.2.407"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1080\/147670410001728223"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(93)91224-A"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(93)90138-7"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyi048"},{"key":"e_1_2_6_12_2","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1159\/000047129","article-title":"Relation between birth weight and placenta weight","volume":"80","author":"Sanin LH","year":"2001","journal-title":"Biology of the Neonate"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-3156.1997.d01-182.x"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1022381506823"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1590\/S1020-49891998000500005"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.87.6.1003"},{"key":"e_1_2_6_17_2","first-page":"693","article-title":"Curvas de crecimiento intrauterino en gemelos mexicanos","volume":"59","author":"Avila\u2010Reyes R","year":"2002","journal-title":"Bolet\u00edn del Hospital Infantil de M\u00e9xico"},{"key":"e_1_2_6_18_2","first-page":"624","article-title":"Fetal growth and perinatal viability in California","volume":"59","author":"Williams RL","year":"1982","journal-title":"Obstetrics and Gynecology"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.37.3.403"},{"key":"e_1_2_6_20_2","first-page":"523","volume-title":"Tratado de Neonatolog\u00eda","author":"Behrman RE.","year":"2001"},{"issue":"3","key":"e_1_2_6_21_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1159\/000091501","article-title":"New definition of small for gestational age based on fetal growth potential","volume":"65","author":"Gardosi J.","year":"2006","journal-title":"Hormone Research"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0029-7844(98)00553-5"},{"key":"e_1_2_6_23_2","first-page":"163","article-title":"El crecimiento intrauterino.
