Iron Status of Women Is Associated with the Iron Concentration of Potable Groundwater in

摘要: Women of reproductive age are at a high risk iron deficiency, often as result diets low in bioavailable iron. In some settings, the content domestic groundwater sources is high, yet its contribution to intake and status has not beenexamined.In ruralBangladeshipopulation womendeficientin dietaryiron, weevaluatedtheassociationbetween groundwateriron status. 2008, participants (n= 209 with complete data) were visited collect data on 7d food frequency, 7-d morbidity history, 24-h drinking water intake, rice preparation, measure concentration. Blood was collected assess infection Plasma ferritin (mg/L) body (mg/kg) concentrationswere[median(IQR)]67(46,99)and10.462.6,respectively,andtheprevalenceofirondeficiency(ferritin, 12 mg/L) 0%. Daily from [42 mg (18, 71)] positively correlated plasma (r = 0.36) totalbodyiron(r= 0.35)(P,0.001for both).Inadjustedlinearregressionanalyses,plasmaferritinincreasedby6.1%(95% CI: 3.8, 8.4%) by 0.3 mg/kg (0.2, 0.4) for every 10-mg increase (P , 0.001). this rural area northern Bangladesh, women had no deficiency likely attributable consumed groundwater, which contributed substantially dietary intake. These findings suggest that should be included assessments such settings. J. Nutr. 141: 944‐949, 2011.
