P12-126 - Determinants of anemia among women and children in rural Bangladesh: a comparison between households with high and low groundwater iron levels

Sunday, Jun 10
8:00 AM – 6:00 PM

Objective:

We aim to identify determinants of anemia among women and children, separately for households reporting groundwater iron consumption and those not.


Methods:


We analyzed data from the Food and Agricultural Approaches to Reducing Malnutrition (FAARM) trial 2015 baseline survey in Sylhet, Bangladesh on 1757 women and their 889 children aged 6-37 months. Determinants of anemia were assessed using multivariable logistic regression with robust standard errors to adjust for village-level clustering. Groundwater iron was assessed by asking women about iron content in their drinking water.


Results:


Women and children in households with reported groundwater iron were less likely to be anemic than those with none (Any: 31% and 46%; None: 37% and 56%, respectively). In both groundwater iron groups, recent pregnancy and lower educational attainment in women and lower child age were associated with higher levels of anemia.

Among women reporting no groundwater iron, heme-iron food or iron supplement consumption was significantly associated with reduced anemia (OR: 0.64; 95% CI (0.42, 0.97)). Among children in these households, no dietary factors were associated with anemia. However, children of underweight mothers (BMI<18.5) were more likely to be anemic (OR: 1.95; 95% CI (1.26, 3.00)).

Among women reporting groundwater iron, consumption of coffee or tea increased the likelihood of anemia (OR: 1.55; 95% CI (1.10, 2.18)). Among their children, consumption of Vitamin C-rich vegetables or fruit was associated with less anemia (OR: 0.57; 95% CI (0.34, 0.94)).


Conclusion:


The influence of dietary factors on anemia seem to differ depending on the presence of groundwater iron in household drinking water. Among women without groundwater iron, increasing dietary iron remains a key strategy. In areas with groundwater iron, making this iron source accessible for intestinal absorption may reduce anemia even without additional dietary iron sources. Furthermore, there is still a large proportion of anemia among both women and children consuming iron from water or dietary sources, which is likely due to causes other than iron deficiency.
