The hypothesis is that lactose digestion and milk tolerance do not change throughout pregnancy anddo not differ from those of non-pregnant African-American women.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980003001071_sec02\"><jats:title>Design and subjects:<\/jats:title><jats:p>This longitudinal study determined lactose digestion after ingesting 240 ml of 1% fat milk containing 12g of lactose at: (1) early pregnancy, prior to 16 weeks (<jats:italic>n<\/jats:italic> = 148); (2) late pregnancy, 30\u201335 weeks (<jats:italic>n<\/jats:italic> = 77); and (3) 8 weeks postpartum (<jats:italic>n<\/jats:italic> = 93). One hundred and one comparably matched non-pregnant African-American women served as controls.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980003001071_sec03\"><jats:title>Results:<\/jats:title><jats:p>Prevalence of lactose digestion, as measured by breath hydrogen, was 80.2% in the control women, 66.2% in early pregnancy, 68.8% in late pregnancy and 75.3% postpartum. The prevalence of women reporting symptoms was approximately 20% regardless of lactose absorption status. However, the control women reported significantly more symptoms than did the pregnant women.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980003001071_sec04\"><jats:title>Conclusions:<\/jats:title><jats:p>This study indicates that there is no significant change in lactose digestion during pregnancy. The prevalence of lactose intolerance for the pregnant African-American women studied is similar to that for non-pregnant African-American women and similar to previous prevalence reports in adult African-Americans. There was no change in the tolerance of lactose noted during pregnancy in these women. There were, however, fewer symptoms reported by the lactose-maldigesting pregnant women.<\/jats:p><\/jats:sec>","DOI":"10.1079\/phn2003489","type":"journal-article","created":{"date-parts":[[2003,11,27]],"date-time":"2003-11-27T00:25:01Z","timestamp":1069892701000},"page":"801-807","source":"Crossref","is-referenced-by-count":7,"title":["Lactose digestion in pregnant African-Americans"],"prefix":"10.1017","volume":"6","author":[{"given":"David M","family":"Paige","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank R","family":"Witter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yvonne L","family":"Bronner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa A","family":"Kessler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jay A","family":"Perman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tara R","family":"Paige","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,1,2]]},"reference":[{"key":"S1368980003001071_ref011","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/58.6.879"},{"key":"S1368980003001071_ref016","first-page":"117","volume-title":"Lactose Digestion: Clinical and Nutritional Implications","author":"Bayless","year":"1981"},{"key":"S1368980003001071_ref017","doi-asserted-by":"crossref","first-page":"447","DOI":"10.1525\/maq.1998.12.4.447","article-title":"\u2018Milk makes me sick but my body needs it\u2019: conflict and contradiction in the establishment of authoritative knowledge","volume":"12","author":"Kingfisher","year":"1998","journal-title":"Medical Anthropology Quarterly"},{"key":"S1368980003001071_ref001","volume-title":"Nutrition During Pregnancy","year":"1990"},{"key":"S1368980003001071_ref003","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/48.2.439"},{"key":"S1368980003001071_ref002","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/48.4.1142"},{"key":"S1368980003001071_ref004","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/26.3.238"},{"key":"S1368980003001071_ref005","first-page":"33","article-title":"Lactose intolerance during pregnancy in different Indian communities","volume":"66","author":"Tandon","year":"1977","journal-title":"Indian Journal of Medical Research"},{"key":"S1368980003001071_ref006","first-page":"697","article-title":"Improved lactose digestion during pregnancy: a case of physiologic adaptation?","volume":"71","author":"Villar","year":"1988","journal-title":"Obstetrics and Gynecology"},{"key":"S1368980003001071_ref007","first-page":"416","article-title":"Lactose handling by women with lactose malabsorption is improved during pregnancy","volume":"19","author":"Szilagyi","year":"1996","journal-title":"Clinical and Investigative Medicine"},{"key":"S1368980003001071_ref008","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(78)80592-7"},{"key":"S1368980003001071_ref009","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2002.05664.x"},{"key":"S1368980003001071_ref010","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1966.03110120074017"},{"key":"S1368980003001071_ref012","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1970.tb03423.x"},{"key":"S1368980003001071_ref013","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2036.2001.00952.x"},{"key":"S1368980003001071_ref014","first-page":"124","volume-title":"Lactose Digestion: Clinical and Nutritional Implications","author":"Newcomer","year":"1981"},{"key":"S1368980003001071_ref015","doi-asserted-by":"publisher","DOI":"10.1007\/BF02088058"}],"container-title":["Public Health Nutrition"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1368980003001071","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T22:17:06Z","timestamp":1557181026000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1368980003001071\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,12]]},"references-count":17,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2003,12]]}},"alternative-id":["S1368980003001071"],"URL":"https:\/\/doi.org\/10.1079\/phn2003489","relation":{},"ISSN":["1368-9800","1475-2727"],"issn-type":[{"value":"1368-9800","type":"print"},{"value":"1475-2727","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,12]]}}}
