Iron status of premenopausal women in two regions of Bangladesh: prevalence of deficiency in high and low socio-economic groups

Abstract
Objective: The objective of the study was to assess iron status in women of different physiological staus of two socio-economic groups in Bangladesh. Design: Cross sectional study, using 3-day food record and blood haemoglobin, serum iron, serum ferritin concentrations. Setting: Two regions of Bangladesh. The Dhaka city area and west region of Nandail, Mymensingh. Subjects: Women aged 16–40 y. The low socio-economic group (group L, n=101) consisted of rural women with precarious income levels. The high socio-economic group (group H, n=90) consisted of women with high income and educational levels. The groups were composed of three sub-groups (non-pregnant non-lactating=1, pregnant = 2 and lactating = 3). Results: There was no significant difference between the corresponding sub-groups of the two socio-economic groups in dietary intake of iron. In all sub-groups, the intake of iron was much higher than the RDA level and mainly based on non-haem iron. Blood haemoglobin (B-Hb) concentration (P=0.000), serum iron concentration (P=0.005) and serum ferritin (SF) concentration (P=0.000) were affected by socio-economic status. Physiological status (PS) influenced the B-Hb concentration (P=0.000). Prevalence of anaemia ranged from 63 to 70% in group L and 27 to 66% in group H, respectively.
