Iron deficiency anaemia in adolescent athletes of the Vila Olímpica Fonndation of Manaus - AM

Considering the dearth of information with regard to the nutritional state of young athletes, were identified the prevalence of iron deficiency anaemia and its association with nutritional indicators of adolescent athletes participating in the Sport Initiation Program of the Vila Olímpica Foundation in Manaus -AM. A sample was made up of 194 voluntary adolescent male athletes classified as beginners, who participated in several different sports. Data collected was by verification of anthropometric measures (body weight, height, and skinfold thicknesses of triceps and subscapular skinfold), hemoglobin dosage utilizing a portable hemoglobinometer, HemoCue direct calorimetric method, and socioeconomic instrument. In the diagnosis of the nutritional states, we used Height-for-age- and Body Mass Index for the age indicators, adjusted cut-off points proposed by the WHO. The results showed that 9.4 % of the adolescents suffered from malnutrition, 8.2% overweight, and 4.6 obesity. The prevalence of iron deficiency anaemia found in the samples was 41.7%, with predominance in the lowest socioeconomic class. Although the prevalence of anaemia was high, the nutritional state of the adolescents did not influence these results, considering that the majority looked healthy. In view of these findings, we suggest that effective means be taken for nutritional education to minimize and/or control iron deficiency anaemia.Considerando a escassez de informações quanto ao estado nutricional de atletas jovens, identificou-se a prevalência de anemia ferropriva e sua associação com indicadores nutricionais de atletas adolescentes participantes do Programa de Iniciação Esportiva da Fundação Vila Olímpica de Manaus-AM. A amostra foi constituída por 194 atletas adolescentes do gênero masculino, voluntários, praticantes de diferentes modalidades esportivas classificados como iniciantes. A coleta dos dados foi realizada mediante verificação de medidas antropométricas (peso corporal, estatura e espessuras das dobras cutâneas tricipital e subescapular), dosagem de hemoglobina utilizando o hemoglobinômetro portátil (Sistema Hemocue) e instrumento socioeconômico. No diagnóstico do estado nutricional foram utilizados os indicadores Estatura para a Idade (E/I) e Índice de Massa Corporal para a idade (IMC/I), assumindo pontos de corte propostos pela OMS. Os resultados mostraram que 9,4% dos adolescentes apresentaram desnutrição, 8,2% sobrepeso e 4,6% obesidade. A prevalência de anemia ferropriva encontrada na amostra foi de 41,7%, com predominância na classe socioeconômica mais baixa. Embora a prevalência de anemia tenha sido elevada, o estado nutricional dos adolescentes não influenciou sobre este resultado, considerando que a maioria dos adolescentes apresentou-se eutrófica. Diante do exposto, sugere-se a adoção de medidas efetivas de intervenção e de educação nutricional visando à minimização e/ou o controle da anemia ferropriva

Minor and trace elements in human milk from Guatemala, Hungary, Nigeria, Philippines, Sweden, and Zaire - Results from a WHO/IAEA joint project

Concentrations of As, Ca, Cd, Cl, Co, Cr, Cu, F, Fe, Hg, I, K, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Se, Sn, V, and Zn were determined in human whole milk samples from Guatemala, Hungary, Nigeria, Phillippines, Sweden, and Zaire; in most of these countries, three groups of subjects representing different socioeconomic conditions were studied. Analytical quality control was a primary consideration throughout. The analytical techniques used were atomic absorption spectrophotometry, atomic emission spectrometry with an inductively coupled plasma, colorimetry, electrochemistry, using an ionselective electrode and neutron activation analysis. The differences between median concentrations of Ca, Cl, Mg, K, Na, and P (minor elements) were lower than 20% among the six countries. Among trace elements, concentrations observed in Filipino milk for As, Cd, Co, Cr, Cu, F, Fe, Mn, Mo, Ni, Pb, Sb, Se, and V were higher than for milk samples from other countries. The remaining five countries showed a mixed picture of high and low values. In the case of at least some elements, such as, F, I, Hg, Mn, Pb, and Se, the environment appears to play a major role in determining their concentrations in human milk. The nutritional status of the mother, as reflected by her socioeconomic status, does not appear to influence significantly the breast milk concentrations of minor and trace elements. Significant differences exist between the actual daily intakes observed in this study and current dietary recommendations made by, for example, WHO and the US National Academy of Sciences. These differences are particularly large (an order of magnitude or more!) for Cr, F, Fe, Mn, and Mo; for other elements, such as, Ca, Cu, Mg, P, and Zn, they amount to at least a factor 2. In the opinion of the present authors, these findings point to the need for a possible reassessment of the dietary requirements of young infants, with respect to minor and trace elements, particularly for the elements Ca, Cr, Cu, F, Fe, Mg, Mn, Mo, P, and Zn. © 1991 Humana Press Inc.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
