“…been observed in studies of North-American adolescents. 3,6 In the present study 11% of adolescents exhibited intake above the EAR, whereas, in a study of 15-year old NorthAmerican children, 30% were consuming more than the recommended dietary allowance (RDA), which is the EAR plus two standard deviations. 7 There is already evidence of the significance of obesity prevalence among adolescents in our country, [8][9][10] It is important to point out that RDA, but not EAR, is applied differently depending on sex.…”

“…Studies that investigated factors that determine low folate consumption found links with socioeconomic status and sex. [3][4][5][6][7] In the context of these considerations the fact that no studies exist that have investigated folate intake among adolescents in Brazil, the objective of this study was to evaluate factors linked with the risk for folate deficiency during this phase of life. Sampling was made by clusters in three stages: first census regions were chosen by systematic lots from the total of 40, next the blocks and street corners where sampling would start were chosen at random and finally residences were sampled systematically with one in three being selected.…”

Objective: To evaluate factors associated with the risk of low folate intake among adolescents.Methods: We employed cluster sampling, using a random selection of 40 representative census sectors and households within those sectors, including all individuals between 10 and 19 years of age. The weight, height and skin folds of subjects were measured and socioeconomic data on their families were collected. A 24-hour dietary recall and frequency questionnaire were used to estimate the quantity and frequency of folate intake. Folate consumption was quantified using Nutwin software. Risk of low folate intake was defined as Folate consumption below the estimated average requirement. The statistical analysis employed hierarchical logistic regression.Results: A total of 722 adolescents were investigated and their mean folate intake was 145±117 µg. The frequency of subjects at risk of having a lower than recommended folate intake was 89%. Adolescents had a greater risk of inadequate folate intake if their body mass index was at or above the 85 th percentile, their waist circumference was at or above the 80 th percentile or they had a family history of cardiovascular disease. Adolescents who ate beans and dark green vegetables less than four times a week also exhibited an increased chance of having folate intake below recommended levels.Conclusions: These adolescents present a high risk of low folate intake and this risk is linked with increasing age, waist circumference above the 80 th percentile and low frequency of beans and dark green vegetables consumption.J Pediatr (Rio J). 2006;82(2):121-6: Adolescent, folic acid, food habits, obesity.

“…On the other hand, mean Fe intake among our subjects was a relatively low, 3?70 mg/4184 kJ with energy adjustment or 6?55 mg/d without. The lower mean Fe intake in Japan than in other developed countries (19)(20)(21)(22) is likely attributed to the different dietary habits of most Japanese, with greater consumption of rice and fish and lower consumption of meat (23) . This difference in Japanese dietary habits also likely influenced bioavailable Fe levels in our study.…”

Objectives: We evaluated the association of nutrient intake with Fe deficiency with regard to lifestyle factors and health condition in young Japanese women. Uniquely among developed countries, dietary habits render Japanese populations vulnerable to Fe deficiency, owing to their relatively low intake of Fe and high intake of Fe absorption inhibitors, such as green tea and soyabeans. Design: A cross-sectional study. Setting and subjects: The subjects were 1019 female Japanese dietetic students aged 18-25 years. Dietary habits during the preceding month were assessed using a previously validated, self-administered, diet history questionnaire. Blood analysis was performed to assess body Fe status. Subjects were categorized with Fe deficiency when their serum ferritin levels were ,12 ng/ml. Twenty-nine dietary variables, i.e. intakes of energy, sixteen nutrients including Fe and twelve food groups, were analysed using multivariate logistic regression models adjusted for possible confounders. Results: Of the subjects, 24?5 % were categorized with Fe deficiency. However, no dietary factors assessed were significantly associated with Fe deficiency. The risk of Fe deficiency was significantly lower in women with infrequent or no menstrual cycles than in those with regular cycles (OR 5 0?58; 95 % CI 0?34, 1?00) and significantly higher in women with heavy menstrual flow than in women with average flow, albeit that these were self-reported (OR 5 1?83; 95 % CI 1?35, 2?48). Conclusions: These results suggest that dietary habits, including Fe intake, do not significantly correlate with Fe deficiency among young Japanese women.

“…A comparação com estudos realizados em outros países é limitada, uma vez que foram utilizados valores de recomendações diferentes e também há divergências quanto aos critérios para adequação de ingestão. Entretanto, é nítido observar que o nível de ingestão apresenta situação muito aquém do encontrado em estudos com adolescentes norte-americanos 3,6 . Enquanto que, neste estudo, 11% dos adolescentes apresentaram ingestão acima da EAR, no estudo com norteamericanos de 15 anos, 30% apresentaram ingestão acima das recommended dietary alowances (RDA), que é a EAR mais dois desvios padrão 7 .…”

“…A análise de alguns estudos internacionais com adolescentes aponta média de ingestão de folato abaixo da estimativa de requerimento médio (estimated average requirement EAR) das novas recomendações 1 e que, nos últimos estudos comparativos, a prevalência de adolescentes com esse comportamento aumentou, sugerindo que o risco para ingestão insuficiente de folato inicia nesse ciclo da vida. Estudos que investigaram os fatores determinantes com o consumo deficiente de folato mostraram associação com o nível socioeconômico e sexo [3][4][5][6][7] .…”

ResumoObjetivo: Avaliar os fatores associados com risco para ingestão deficiente de folato entre adolescentes.Métodos: O processo amostral deu-se por conglomerados através de sorteio sistemático de 40 setores censitários e dos domicílios, incluindo todos os indivíduos com idade entre 10 e 19 anos. Foram obtidos as medidas de peso, estatura, dobras cutâneas dos adolescentes e dados sociodemográficos da família. Utilizou-se o inquérito recordatório de 24 horas e inquérito de freqüência alimentar. A determinação do folato presente nos alimentos foi realizada por meio do programa Nutwin. Foi considerado risco para ingestão insuficiente quando a ingestão de folato era menor que a estimativa de requerimento médio. A análise estatística foi realizada por meio de regressão logística, utilizando modelo hierárquico.Resultados: Os resultados foram obtidos com 722 adolescentes, com média de ingestão de folato de 145±117 µg e freqüência de adolescentes com risco de ingestão de folato abaixo da recomendação de 89%. Observou-se que os adolescentes com índice de massa corporal > ao percentil 85, aqueles com a circunferência da cintura > ao percentil 80 e com antecedentes familiares de doenças cardiovasculares, além do consumo não habitual de feijão e de vegetais verdeescuros, foram associados positivamente com a maior chance de risco para consumo insuficiente.Conclusões: Os adolescentes apres...
