Specifically designed case report forms collected information and measurements prospectively.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n After reviewing the medical records of 5806 women, it was possible to identify those who had spontaneous preterm birth (\n SPTB<\/jats:styled-content>\n ), induced preterm birth (\n IPTB<\/jats:styled-content>\n ), or spontaneous term birth (\n STB<\/jats:styled-content>\n ). Women with\n IPTB<\/jats:styled-content>\n (vs\n SPTB<\/jats:styled-content>\n ) were more obese and had higher education levels and household incomes; more had telephones and running water at home. They enrolled earlier and more developed hypertension and pre\u2010eclampsia. Women with\n SPTB<\/jats:styled-content>\n (vs\n STB<\/jats:styled-content>\n ) were less obese, shorter, had smaller arm circumferences and higher gravidities and Edinburgh Depression Scores, lower education, fewer telephones, and less running water at home. More women with\n SPTB<\/jats:styled-content>\n used methamphetamine, cigarettes, and were heavier smokers.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n SPTB<\/jats:styled-content>\n and\n IPTB<\/jats:styled-content>\n should not be conflated. Programs to reduce the high prevalence of\n SPTB<\/jats:styled-content>\n should include improving education, lifestyle, and socioeconomic conditions. Addressing hypertension should help reduce preterm inductions.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/ijgo.13143","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T10:35:38Z","timestamp":1584354938000},"page":"359-369","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Association of socioeconomic status and clinical and demographic conditions with the prevalence of preterm birth"],"prefix":"10.1002","volume":"149","author":[{"given":"Lucy T.","family":"Brink","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynaecology Faculty of Medicine and Health Sciences Stellenbosch University Tygerberg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daan G.","family":"Nel","sequence":"additional","affiliation":[{"name":"Department of Statistics and Actuarial Science Stellenbosch University Stellenbosch South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David R.","family":"Hall","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology Faculty of Medicine and Health Sciences Stellenbosch University Tygerberg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hein J.","family":"Odendaal","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology Faculty of Medicine and Health Sciences Stellenbosch University Tygerberg South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,4,8]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.7196\/SAMJ.2019.v109i2.13438"},{"key":"e_1_2_8_3_1","first-page":"1","volume-title":"Born Too Soon.
