Number approached: 12 373 women, response rate: 67% (8266 women aged 14\u201349 years).

Language proficiency in Dutch was a major determinant of knowledge in all the ethnic groups with a mother tongue other than Dutch [adjusted odds ratios (OR): Western 3.2, non\u2010Western (all countries combined) 7.5], while educational attainment was of secondary importance.

Measures to tackle this problem include the provision of linguistically appropriate information via ethnic health advisors, and language courses integrating health education for immigrants.<\/jats:p>","DOI":"10.1111\/j.1471-0528.2006.01096.x","type":"journal-article","created":{"date-parts":[[2006,11,2]],"date-time":"2006-11-02T19:49:36Z","timestamp":1162496976000},"page":"1446-1451","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Folic acid knowledge and use in a multi\u2010ethnic pregnancy cohort: the role of language proficiency"],"prefix":"10.1111","volume":"113","author":[{"given":"M","family":"Van Eijsden","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MF","family":"Van Der Wal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GJ","family":"Bonsel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,11,10]]},"reference":[{"key":"e_1_2_7_2_2","first-page":"14","article-title":"Racial differences in late prenatal care visits","volume":"13","author":"Kogan MD","year":"1993","journal-title":"J Perinatol"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/pubmed\/fdg025"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1067\/S0002-9378(03)01055-X"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(16)32826-5"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1067\/mob.2002.122446"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/1077558700057001S06"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/jech.55.10.701"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2003.08.004"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1023\/B:MACI.0000037645.63379.62"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.80.Suppl.11"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005650-200201000-00007"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1177\/107755870005700105"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-1497.2004.40103.x"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1497.1997.00085.x"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1093\/fampra\/16.4.369"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.38336.664352.82"},{"key":"e_1_2_7_18_2","first-page":"2426","article-title":"Awareness and periconceptional use of folic acid among non\u2010western and western women in the Netherlands following the 1995 publicity campaign (in Dutch)","volume":"147","author":"Bakker MK","year":"2003","journal-title":"Ned Tijdschr Geneeskd"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1093\/fampra\/18.3.300"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-3016.2000.00251.x"},{"key":"e_1_2_7_21_2","volume-title":"Standard Definition Ethnic Minorities (in Dutch)","author":"Central Bureau of Statistics","year":"2000"},{"key":"e_1_2_7_22_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0412.2000.079006513.x"},{"key":"e_1_2_7_23_2","doi-asserted-by":"crossref","first-page":"259","DOI":"10.1007\/BF03405012","article-title":"Pregnancy planning: a determinant of folic acid supplements use for the primary prevention of neural tube defects","volume":"93","author":"Morin P","year":"2002","journal-title":"Can J Public Health"},{"key":"e_1_2_7_24_2","doi-asserted-by":"crossref","first-page":"1142","DOI":"10.1542\/peds.111.S1.1142","article-title":"Pregnancy intendedness and the use of periconceptional folic acid","volume":"111","author":"Rosenberg KD","year":"2003","journal-title":"Pediatrics"},{"key":"e_1_2_7_25_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-3016.2003.00497.x"},{"key":"e_1_2_7_26_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2524.1998.00148.x"},{"key":"e_1_2_7_27_2","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/24.Supplement_1.S79"},{"key":"e_1_2_7_28_2","first-page":"64","volume-title":"Evidence\u2010based Health Promotion","author":"Lawrence T","year":"1999"},{"key":"e_1_2_7_29_2","doi-asserted-by":"publisher","DOI":"10.1136\/jech.52.8.501"},{"key":"e_1_2_7_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0277-9536(99)00418-9"},{"key":"e_1_2_7_31_2","volume-title":"Folic Acid Use and Health Behaviour in Pregnancy: a Study into Determinants of Behaviour of Pregnant Women with Different Cultural Backgrounds and Socio\u2010economic Status (in Dutch)","author":"Van Vree F","year":"2003"},{"key":"e_1_2_7_32_2","doi-asserted-by":"publisher","DOI":"10.1177\/0739986300223008"}],"container-title":["BJOG: An International Journal of Obstetrics &amp;
