“…The prevalence of anemia among adolescents found in this study (13.1%) was lower than that obtained in an analysis conducted with children and adolescents aged between 7 and 14 years in the public education network of Salvador, Bahia (24.7%) 23 , and in a study conducted with adolescent girls aged between 10 and 18 years in the education network of Balneário Camboriú, in Santa Catarina (31.1%) 24 . The lowest prevalence (7.3%) was observed in the public elementary schools in the suburbs of Vespasiano, city in Minas Gerais, in which 736 girls aged between 11 and 16 years were assessed 25 .…”

ABSTRACT:Objective: To identify the prevalence of iron-deficiency anemia and associated factors in women at reproductive age in the city of Vitoria de Santo Antão, Pernambuco. Methods: Cross-sectional study with a representative sample of 322 women aged between 15 and 49 years. Anemia was diagnosed by measuring hemoglobin below 12 g/dL. The independent variables were: demographic and socioeconomic conditions (age, race/color, education, literacy, presence of children aged < 5 years in the household, regime of residence occupation, ownership of assets, and per capita income), housing conditions (number of people in the household, number of bedrooms, and basic sanitation), food and nutrition security and women's health conditions (menarche, number of pregnancies, history of miscarriages, body mass index, and ferritin). Poisson regression was used to analyze the factors associated with anemia. Results: The mean age of women surveyed was 31.1 ± 6.61 years old (standard deviation -SD) and the prevalence of anemia was 18.6% . After multivariate analysis, anemia was significantly associated with age ≤ 19 years and low ferritin. Conclusion: The prevalence of anemia is characterized as a mild public health problem and follows the world trend in developing countries.

“…The lower iron intake observed among 14 to 18 year olds makes them more vulnerable to anemia due to lack of iron, which is highly prevalent among Brazilian adolescents of both genders. 24 The greater inadequacy of iron observed in females compared to males of the same age, in the second half of adolescence, may be associated with this group's lower intake of the nutrient, as the values of the percentiles are lower than the values for the males, although needs are similar for both groups (7.9 mg for females and 7.7 mg for males).…”

OBJECTIVE: to assess energy and nutrient consumption and the prevalence of inadequate micronutrient intake among Brazilian adolescents. METHODS:A random sample composed of 6,797 adolescents (49.7% girls), between 10 and 18 years old, was evaluated in the fi rst National Dietary Survey, part of the Household Budget Survey carried out in [2008][2009]. Expansion factors, sample complexity design and correction of intraindividual variability were considered. The prevalence of inadequate micronutrient intake was based on the proportion of adolescents with intake below the Estimated Average Requirement. The prevalence of intake above the Tolerable Upper Intake Level (UL) was estimated for sodium. RESULTS:The mean energy intake ranged between 1,869 kcal (10 to 13 year old females) and 2,198 kcal (14 to 18 year old males). Of the total energy intake, 57% came from carbohydrates, 27% from lipids and about 16% from proteins. Inadequacies were higher for calcium (> 95%), phosphorous (54% to 69%) and vitamins A (66% to 85%), E (100%) and C (27% to 49%). More than 70% of adolescents reported sodium intake above the UL. CONCLUSIONS:Mean energy consumption and distribution of macronutrients were adequate, but prevalence of inadequate vitamin and mineral intake were high and notable consumption of sodium above the recommended levels, low levels of calcium consumption and, in 14 to 18 year old females, important inadequacies in iron intake were found.

“…This percentage is expected in this population, according to the WHO [18]. This value is far below those found in some regional studies conducted in Brazil [5,7]. In 2004, the prevalence of iron deficiency was found to be 14.5% (37 individuals), of which 64.4% (24) were male, and 35.6% (13) female [9].…”

“…Regional studies have observed that the prevalence of anemia on both sex ranges from 6.4 to 41.7% [3][4][5][6][7][8], in females from 7.5 to 31.1% [4][5][6][7] and males from 6.0 to 31.4% [4][5][6]. The prevalence of iron deficiency on both sexes is 21.2% [3], in females 10.3% and in males 18.6% [9].…”

Background: As it is difficult to know the content of iron added in the Brazilian iron fortification of wheat and corn flour, and if the compound has good or poor bioavailability, the objective was to assess the effect of the Brazilian iron fortification program, as it was carried out, on iron nutritional status of adolescents, 6 years after its implementation. Methods: A cross-sectional retrospective study was conducted with adolescents aged 10 to 17 years, both sexes, treated at a primary health care center. Data were collected from medical records of patients and compared with those of a previous survey conducted at the same center in 2004. Anthropometry, iron biochemical indicators, food intake, pubertal stage, and transferrin saturation were assessed, with pubertal stage and transferrin saturation being the last two variables compared between 2004 and 2010. Mann-Whitney and chi-square tests were also used. Results: In 2010, mean hemoglobin values and serum ferritin levels were within normal ranges for both sexes, and adolescents who consumed diets with low iron bioavailability constituted more than half of the sample (52.7%). In 2004, a 10.3 and 18.6% prevalence of iron deficiency was observed, based on low transferrin saturation, in females and males, respectively. It was noted that during the 6-year period, this prevalence decreased significantly, 4 and 10.4%. Conclusions: Anemia and iron deficiency are not prevalent in this population, probably due to the implementation of flour fortification with iron; it is not possible, however, to attribute such a result only to the implementation of this strategy.
