Abstract

OBJECTIVES: To determine the rate of iron deficiency in women coming for antenatal care and to asses whether the haemoglobin concentration is a good index in its detection. DESIGN: A cross sectional cohort study. SETTING: University antenatal clinic, Teaching Hospital, Galle. SUBJECTS: Haemoglobin (Hb), haematocrit (HC) and serum ferritin (SF) were estimated in 236 women. RESULTS: Only 7(3%) women had satisfactory iron stores as shown by SF of over 60 ng/ml. SF levels of less than 10 ng/ml indicating complete depletion of iron stores were found in 135(57%). An Hb level of 11 g/dl, which is the recommended cut off point for the diagnosis of anaemia, had a sensitivity of 63% and a negative predictive value of 41% in the detection of iron deficiency in the study population. The SF was poorly correlated to the Hb at Hb levels of more than 11 g/dl. (r2 = 0.000342, P > 0.5). CONCLUSION: In women attending for antenatal care the rate of iron deficiency is high (69%). The haemoglobin concentration is not a good index to detect this.
