          Abstract

          Objective

          The aim of this study was to evaluate the prevalence and risk factors of anemia among adolescents in Denizli where Mediterranean cuisine (fresh fruit and vegetables) is adopted.

          Methods

          We accepted hemoglobin values below 12 g/dl for girls and 13 g/dl for boys as the criteria of anemia. We recorded a detailed history including nutritional habits, consumption of animal source foods especially red meat, consumption of fresh fruit and vegetables, presence of parasitic infestation, psychosocial status, school success and any materials consumed except ordinary food.

          Findings

          We investigated the prevalence of anemia in 1120 children (672 girls and 448 boys), aged 12 to 16 years. We found that the overall prevalence of anemia was 5.6%. 8.3% of the girls and 1.6% of the boys were anemic. We diagnosed iron deficiency anemia in 37(59%) anemic patients and combined iron deficiency and vitamin B12 deficiency anemia in 26 (41%) anemic patients. None of the patients had folic acid deficiency.

          Conclusion

          Our results suggest that the socioeconomic status of the family, traditional eating habits of the region, the fear of gaining weight and irregular eating habits are of great importance in the development of adolescent anemia in Denizli.

          Iron deficiency and cognitive achievement among school-aged children and adolescents in the United States.

          Iron deficiency anemia in infants can cause developmental problems. However, the relationship between iron status and cognitive achievement in older children is less clear. To investigate the relationship between iron deficiency and cognitive test scores among a nationally representative sample of school-aged children and adolescents. The National Health and Nutrition Examination Survey III 1988-1994 provides cross-sectional data for children 6 to 16 years old and contains measures of iron status including transferrin saturation, free erythrocyte protoporphyrin, and serum ferritin. Children were considered iron-deficient if any 2 of these values were abnormal for age and gender, and standard hemoglobin values were used to detect anemia. Scores from standardized tests were compared for children with normal iron status, iron deficiency without anemia, and iron deficiency with anemia. Logistic regression was used to estimate the association of iron status and below average test scores, controlling for confounding factors. Among the 5398 children in the sample, 3% were iron-deficient. The prevalence of iron deficiency was highest among adolescent girls (8.7%). Average math scores were lower for children with iron deficiency with and without anemia, compared with children with normal iron status (86.4 and 87.4 vs 93.7). By logistic regression, children with iron deficiency had greater than twice the risk of scoring below average in math than did children with normal iron status (odds ratio: 2.3; 95% confidence interval: 1.1-4.4). This elevated risk was present even for iron-deficient children without anemia (odds ratio: 2.4; 95% confidence interval: 1.1-5.2). We demonstrated lower standardized math scores among iron-deficient school-aged children and adolescents, including those with iron deficiency without anemia. Screening for iron deficiency without anemia may be warranted for children at risk.

            Iron requirements in adolescent females.

            Adolescence is characterized by a large growth spurt and the acquisition of adult phenotypes and biologic rhythms. During this period, iron requirements increase dramatically in both boys and girls as a result of the expansion of the total blood volume, the increase in lean body mass and the onset of menses in young females. The overall iron requirements increase from a preadolescent level of approximately 0.7-0.9 mg Fe/d to as much as 2.2 mg Fe/d or perhaps more in heavily menstruating young women. These increased requirements are associated with the timing and size of the growth spurt as well as sexual maturation and the onset of menses. The available data on iron intakes in adolescents suggest that adolescent girls are unlikely to acquire substantial iron stores during this time period because intakes may average as little as 10-11 mg Fe/d. The bioavailability from diets in developing and industrialized countries indicates a negative iron balance is likely in many female populations. The low iron stores in these young women of reproductive age will make them susceptible to iron deficiency anemia during pregnancy because dietary intakes alone are insufficient, in most cases, to meet the requirements of pregnancy.

              Iron requirements in menstruating women.

              Total-absorbed-iron requirements in adult and teen-age menstruating women were calculated from previously published data on menstrual blood losses; hemoglobin distribution in healthy, nonanemic women; basal iron losses; and growth requirements in teen-agers. Because present calculations included the effect of the variation of all indices, the new requirements for iron were increased to 2.84 mg/d in adult women and 3.21 mg/d in teen-agers (95th percentiles). Six independent estimations of whole-diet iron bioavailability were made to translate absorbed iron requirements into dietary requirements. In subjects with no iron stores, estimated dietary iron bioavailability amounted to 14% (Swedish diet), 16% (French diet), and 16.6% (US diet). When 15% was used as a single figure to represent the optimal, long-term bioavailability of iron in a general Western-type diet, the 95th percentiles of dietary iron requirements were 18.9 mg in adult menstruating women and 21.4 mg in menstruating teenagers.
