Preterm birth has a major impact on growth, and very preterm birth is associated with disabilities in numerous developmental domains. This article describes and quantifies morbidities in a sample of 1200 \u22641500-g births in Spain between 1993 and 2011 based on parent information, and it highlights several variables that influence these morbidities. Methods. Multiple method surveys using computer-assisted telephones interviewing and computer-assisted web interviewing methods. Sample design was intentional. Most subjects were contacted via their referral hospitals. Data collection was done from April 2013 to June 2014. Prior to the survey, extensive qualitative fieldwork was conducted, including nonparticipant observation in neonatal units and the design and analysis of discussion groups and interviews with professionals and families, including preterm adolescents. Results. A total of 44.2% of the sample were experiencing morbidity (mean: 1.788 morbidities per child). The most prevalent types were learning difficulties (34.4%) and attention deficit\/hyperactivity disorder (31.5%). The most influential variables were male gender, age, lower birthweight, private hospital admission for birth, scarcity of health resources in the family\u2019s residential area, non-Spanish maternal birthplace, and emotional distress in the primary carer. Conclusions. Overall, the total percentage of very low birth weight children with morbidities has decreased moderately between 1993 and 2011, thanks to major socio-sanitary improvements during this period. Biological and medical variables, rather than family factors, explain more accurately the presence of morbidities in children with birth weight \u22641500 g.<\/jats:p>","DOI":"10.1177\/2333794x17733372","type":"journal-article","created":{"date-parts":[[2017,9,28]],"date-time":"2017-09-28T07:47:45Z","timestamp":1506584865000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Morbidity in \u22641500-Gram Births in Spain, 1993-2011: Study of a Sample of 1200 Cases"],"prefix":"10.1177","volume":"4","author":[{"given":"Concepci\u00f3n","family":"G\u00f3mez Esteban","sequence":"first","affiliation":[{"name":"Complutense University of Madrid, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan J.","family":"S\u00e1nchez Carri\u00f3n","sequence":"additional","affiliation":[{"name":"Complutense University of Madrid, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando J.","family":"Garc\u00eda Selgas","sequence":"additional","affiliation":[{"name":"Complutense University of Madrid, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 M.","family":"Segovia Guisado","sequence":"additional","affiliation":[{"name":"Complutense University of Madrid, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,9,28]]},"reference":[{"key":"bibr1-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.e7976"},{"key":"bibr2-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2013-2024"},{"key":"bibr3-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2006-2407"},{"key":"bibr4-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(08)60380-3"},{"key":"bibr5-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(08)60136-1"},{"key":"bibr6-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2016.04.083"},{"key":"bibr7-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2009.06.001"},{"key":"bibr8-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.2010.03730.x"},{"key":"bibr9-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1111\/apa.12900"},{"key":"bibr10-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.5569\/2340-5104.02.01.12"},{"key":"bibr11-2333794X17733372","doi-asserted-by":"publisher","DOI":"10.1157\/13073244"},{"key":"bibr12-2333794X17733372","unstructured":"Guzm\u00e1n Caba\u00f1as JM, del Prado N, Fern\u00e1ndez P\u00e9rez C, et al; Red SEN1500.
