Knowledge and practices of dietary iron and anemia among early adolescents in a rural district in Ghana

The study assessed knowledge and practices of dietary iron intake and anemia among early adolescents in the Asante‐Akim Municipality of Ghana. A cross‐sectional study was conducted among 137 adolescents, aged 10–14 years. Structured questionnaire was used to collect data on sociodemographic, knowledge of iron, and anemia, and iron intake practices. Hemoglobin levels were determined using Hemocue 301. Data were analyzed using descriptive, chi‐square test, and binary logistics regression. The mean age of participants was 11.5 years. About 40% had knowledge of iron deficiency anemia, 29.4% knew anemia causes, 86% knew symptoms of anemia, and 35% knew anemia consequences. Although 41.2% of participants knew its prevention as eating iron‐rich foods, 31.4% knew the food sources of iron, and 4.4% mentioned animal‐based foods as rich sources, with the bulk (27%) mentioning plant‐based foods instead. Moreover, 18.2% knew iron enhancers, while 0.7% knew iron inhibitors. More chicken consumers (72.2%) than nonconsumers (56.6%) met the Estimated Average Requirement for dietary iron intake (Chi‐square 3.4, p = .073), while more dried fish consumers (88%) than nonconsumers (66.7%) had normal hemoglobin levels (Chi‐square 4.5, p = .050). Knowledge of food sources of iron and iron‐rich foods was positively associated with intake of chicken, fresh fish, and dried fish. Moreover, lower knowledge of iron‐based food sources (β = −1.015, p = .020) and iron‐rich foods (β = −2.188, p = .015) was inversely associated with beef intake. Anemia was negatively associated with chicken (β = −0.310, p = .416) and dried fish (β = −1.299, p = .045) consumption. Majority of the adolescents had low knowledge of iron. Chicken and dried fish intake reduced the risk of anemia development. Our study may be the first to assess knowledge on iron, anemia, and its impact among young Ghanaian adolescents. Our findings provide insights into this topic, calling for to improve knowledge, and practices on anemia in Ghanaian adolescents.
Anaemia, a type of micronutrient deficiency, is known to affect the physical and cognitive abilities of adolescents. The study assessed knowledge and practices of dietary iron intake and anaemia. Results show that majority of adolescents had little knowledge of iron, causes of anaemia and sources of iron‐rich foods.
