ObjectiveUsing data from the national micronutrients survey 2011-2012, the present study explored the determinants of Fe status and Hb levels in Bangladesh with a particular focus on groundwater Fe.DesignCross-sectional study conducted at the nationwide scale.SettingsThe survey was conducted in 150 clusters, fifty in each of the three strata of rural, urban and slum.SubjectsThree population groups: pre-school age children (6-59 months; PSAC), school age children (6-14 years; SAC) and non-pregnant non-lactating women (15-49 years; NPNLW).ResultsNational prevalence of Fe deficiency was 107 %, 71 % and 39-95 % in PSAC, NPNLW and SAC, respectively. Prevalence of anaemia was 331 % (PSAC), 260 % (NPNLW) and 171-191 % (SAC). Multivariate regression analyses showed that the area with predominantly high groundwater Fe' was a determinant of higher serum ferritin levels in NPNLW (standardized =019; P=003), SAC (standardized =022; P=001) and PSAC (standardized =020; P=003). This area also determined higher levels of Hb in PSAC (standardized =014; P=001).ConclusionsNational prevalence of Fe deficiency in Bangladesh is low, contrary to the widely held assumption. High Fe level in groundwater is associated with higher Fe status (all populations) and higher Hb level (PSAC).
