Anemia in pregnancy in rural Tanzania: associations with micronutrients status and infections

We studied the association between anemia in pregnancy and characteristics related to nutrition and infections. Cross-sectional study. Four antenatal clinics in rural northern Tanzania. A total of 2547 women were screened for hemoglobin (Hb) and malaria plasmodia in capillary blood and for infections in urine. According to their Hb, they were assigned to one of five groups and selected accordingly, Hb or =150 g/l (n=50). The 312 selected subjects had venous blood drawn, were interviewed, and their arm circumference was measured. The sera were analyzed for ferritin, iron, total iron binding capacity (TIBC), cobalamin, folate, vitamin A, C-reactive protein (CRP), and lactate dehydrogenase (LD). Transferrin saturation (TFsat) was calculated. Urine was examined by dipsticks for nitrite. Unadjusted and adjusted odds ratio (OR and AOR) of anemia with Hb
