Twenty-four children aged 4\u201310 years were screened and in every case eggs of either <jats:italic>Ascaris, Trichuris<\/jats:italic> or hookworm were isolated from the stool. The average serum retinol was 0.91 (sd 0.35) \u03bcmol\/l and sixteen children had levels below 1.05 \u03bcmol\/l. This compared with a serum retinol concentration of 1.70 (sd 0.52) \u03bcmol\/l in five reference children from a more privileged social background. An oral dose of retinol (41.8 \u03bcmol) was given, to ten children in whom the concentration of <jats:italic>Ascaris<\/jats:italic> eggs in the stool varied. Less than 1% of the supplement could be recovered in the stools collected over the following 48 h. <jats:italic>Ascaris<\/jats:italic> worms were isolated from the stool and assayed for retinol content. In no case was retinol detected in the worms. These findings do not support the contention that infection with <jats:italic>Ascaris<\/jats:italic> predisposes to malabsorption of vitamin A.<\/jats:p>","DOI":"10.1079\/bjn19930082","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T04:07:20Z","timestamp":1126930040000},"page":"817-825","source":"Crossref","is-referenced-by-count":26,"title":["Vitamin A absorption in children with ascariasis"],"prefix":"10.1017","volume":"69","author":[{"given":"F.","family":"Ahmed","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Mohiduzzaman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
