A double burden of overall or central adiposity and anemia or iron deficiency is prevalent but with little socioeconomic patterning among moroccan and tunisian urban women

Abstract

In North Africa, overnutrition has dramatically increased with the nutrition transition while micronutrient deficiencies persist, resulting in clustering of opposite types of malnutrition that can present a unique difficulty for public health interventions. We assessed the magnitude of the double burden of malnutrition among urban Moroccan and Tunisian women, as defined by the coexistence of overall or central adiposity and anemia or iron deficiency (ID), and explored the sociodemographic patterning of individual double burden. In cross-sectional surveys representative of the region around the capital city, we randomly selected 811 and 1689 nonpregnant women aged 20-49 y in Morocco and Tunisia, respectively. Four double burdens were analyzed: overweight (body mass index ≥25 kg/m2) or increased risk abdominal obesity (waist circumference ≥80 cm) and anemia (blood hemoglobin <120 g/L) or ID (C-reactive protein-corrected serum ferritin <15 μg/L). Adjusted associations with 9 sociodemographic factors were estimated by logistic regression. The prevalence of overweight and ID was 67.0% and 45.2% in Morocco, respectively, and 69.5% and 27.0% in Tunisia, respectively, illustrating the population-level double burden. The coexistence of overall or central adiposity with ID was found in 29.8% and 30.1% of women inMorocco, respectively, and in 18.2% and 18.3%of women in Tunisia, respectively, quite evenly distributed across age, economic, or education groups. Generally, the rare, associated sociodemographic factors varied across the 4 subject-level double burdens and the 2 countries and differed fromthose usually associated with adiposity, anemia, or ID. Any double burden combining adiposity and anemia or ID should therefore be taken into consideration in all women. This trial was registered at clinicaltrials. © 2014 American Society for Nutrition.
