【 摘 要 】

ObjectiveThe objective of the current analysis was to explore the association of multiple micronutrients with Hb concentration among pregnant women in a South Asian setting, a topic that has not been adequately explored.DesignSociodemographic, anthropometric and micronutrient status (plasma ferritin, transferrin receptor, retinol, α- and γ-tocopherol, folate, vitamin B12, Zn) and Hb concentration were assessed at early pregnancy.SettingThe biochemical sub-study was nested within a double-blind, placebo-controlled, community-based vitamin A and β-carotene supplementation trial in rural north-western Bangladesh (JiVitA). All assessments were conducted before trial supplementation was initiated.SubjectsA systematic sample of 285 women was selected from those enrolled in the biochemical sub-study.ResultsSeventeen per cent of women were mildly anaemic; moderate and severe anaemia was uncommon (2·1 %). α-Tocopherol, vitamin B12 and Zn deficiencies were common (43·5 %, 19·7 % and 14·7 %, respectively); however, vitamin A, folate and Fe deficiencies were comparatively rare (7·4 %, 2·8 % and
