HFIAS, Household Food Insecurity Access Scale. The dependent (hemoglobin concentration) and all independent variables are continuous. Coding: Age of women (18–52 years), body mass index (15.4–26.1 kg/m2), Gravidity (0–14), household size (0–12), school years attended (0–12), land size (0–1.5 ha), HFIAS scores ranging from (0 [no food insecurity] to 27 [the most food insecurity], weekly enset products consumption (3–7), weekly maize consumption (3–7), weekly kale consumption (3–7), transferrin saturation (4.0–92%), and body iron (-15.8 to 19.2 mg/kg).
