Abstract

Proper nutrition is very important for good health. A cross-sectional study on 352 adolescent girls to evaluate nutrition knowledge, practices and actual diet. Results: 83.2% of the subjects understood about the deficiencies of calcium and vitamin D, but the prevalence of regular milk consumption was low (23.9%). The ratio of P:L:G was unbalanced (16%:14%:70%). Vitamin D intake was 0.4 µg, calcium was 353 mg; zinc was 6.2 mg and iron was 8.4 mg. Ca:P ratio was 1:1.25. 85.4% of the subjects had dietary calcium intake below 500 mg/day. Conclusions: Adolescent girls had good knowledge on calcium and vitamin D, but did not turn in good practices. Dietary intake of adolescent girls lacked in both quantity and quality and was unbalanced. There is a need for education to improve knowledge of calcium and vitamin D, to increase the intake of dairy products, supplements or calcium and vitamin D fortified foods to prevent calcium, vitamin D deficiencies.
