Micronutrient adequacy of women's diet in urban Burkina Faso is low

Abstract

In developing countries, urban populations are deemed to have better access to a wider variety of foods than their rural counterparts. Yet, data on micronutrient status are scarce and the impact of urban food consumption behaviors on micronutrient adequacy is not well known. The objective of this study was to assess individual micronutrient adequacy of the diet along with food consumption behaviors of women of reproductive age in Ouagadougou, Burkina Faso. A cross-sectional survey of 182 women was conducted in 2 districts of the city. Nutrient intakes were derived from 3 nonconsecutive quantitative 24-h recalls for each woman. Balance in macronutrients was in the range of recommendations except that mean sugar intake was somewhat high. Mean probability of adequacy across 11 micronutrients was low (0.38). The most problematic micronutrients were vitamin B-12 (only 4% of our sample had sufficient intake), folate (12%), riboflavin (13%), and niacin (20%). Higher intakes of organ meat, flesh foods, vitamin A- and vitamin C-rich fruits and vegetables, and legumes and nuts were significantly associated with lower risk of micronutrient inadequacy. Ready-to-eat foods bought outside the home provided 46% of overall energy intake, 52% of fat intake, and 72% of sugar intake but were not associated with micronutrient inadequacy (P > 0.05). These results highlight the low micronutrient intakes among women of reproductive age in Burkina Faso, even in an urban area.
