Iron status of adolescent girls from two boarding schools in southern Benin.
Iron deficiency (ID) is the most prevalent micronutrient deficiency in the world, particularly in developing countries. Blood samples and a qualitative FFQ on Fe- and vitamin C-rich foods were obtained in 180 adolescent girls aged 12 to 17 years living in two boarding schools from south Benin. ID, defined as serum ferritin either 73 micromol/l or transferrin saturation<20%, was found in 32% of subjects. Anaemia (Hb<120 g/l) was found in 51% of adolescents, while 24% suffered from iron-deficiency anaemia (IDA) (ID and Hb<20 g/l). After adjusting for confounding factors (age, mother's and father's occupation, household size) in a logistic regression equation, subjects having a low meat consumption (beef, mutton, pork) (<4 times/week) were more than twice as likely to suffer from ID (OR=2.43; 95% CI 1.72, 3.35; P=0.04). Adolescents consuming less fruits (<4 times/week) also had a higher likelihood of suffering from ID (OR=1.53; 95% CI 1.31, 2.80; P=0.03). Finally, subjects whose meat consumption was low were twice as likely to suffer from IDA (OR=2.24; 95% CI 1.01, 4.96; P=0.04). The prevalence of ID represents an important health problem in these Beninese adolescent girls. A higher consumption of Fe-rich foods and of promoters of Fe absorption (meat factor and vitamin C) is recommended to prevent ID deficiency in these subjects.
