“…This is a cross-sectional study of Confirmatory Factor Analysis (CFA) of a questionnaire to assess the cognition of women about how to combine foods to make dietary iron available. The questionnaire derived from an exploratory study [9] and has two dimensions: "stimulators of iron absorption in the diet" (S) and "inhibitors of iron absorption in the diet" (I), Table1.…”

Objective: to validate an instrument designed to assess the knowledge of adult women about combining foods to make dietary iron more bioavailable. Design Study: cross-sectional, Confirmatory Factor Analysis (CFA). Place and Duration: Rio de Janeiro, Brazil, May 2018 and February 2019. Methodology: sample: n=222 women 15 to 49 years old, not pregnant. The questionnaire was designed on Likert scale. Kaiser-Meyer-Olkin (KMO) and Doornik-Hansen tests were applied, as well as the AFC models with Promax rotation. Convergent validity (CV) and discriminant validity (DV) and reliability (Cronbach's alpha) were evaluated. The Quality of Model Fit was Assessed by: Root Mean Square Error of Approximation (RMSEA), Comparative Fit Index (CFI) and the Tucker-Lewis Index (TLI). The dimensional structure of the questionnaire was reevaluated by Structural Equation Modeling (Modification Indices (MI) and Expected Parameter Changes (EPC). Results: Initial model: total KMO 0.75 (min = 0.63, max = 0.84), Doornik-Hansen (chi2 (30) = 208.91, P = .00), eigenvalue (F1 = 2.87 and F2 = 1.98), CV not reached (F1: AVE = 0.30 and F2: AVE = 0.21) and DV corroborated, Conbrach alphas reached for 0.75 inhibitory items ( 95% CI = 0.69 to 0.81), for stimulators: 0.62 (95% CI = 0.51 to 0.70), RMSEA = 0.10 (90% CI = 0.08 to 0.11 ), CFI (0.70), TLI (0.65), items with MI>10 (i16I, i23E, i25E, i28E). Re-specified Model: eigenvalue (F1 = 2.44 and F2 = 1.42), CV not reached (F1: AVE= 0.29 and F2: AVE=0.20) and corroborated DVl, Conbrach alphas: for 0.75 inhibitory items (95% CI = 0.69 to 0.81); stimulators items: 0.55 (95% CI = 0.44 to 0.64), RMSEA = 0.03 (90% CI = 0.00 to 0.06), CFI (0.95), TLI (0, 94). The items did not show MI>10. Conclusion: The reliability was achieved in both models. Validities: convergent was not achieved and the discriminant attested two-dimensionality.

O presente estudo objetivou caracterizar na população infantil ribeirinha da Ilha do Combu, de zero (0) a 12 anos de idade, a ocorrência de anemia ferropriva, identificando a prevalência e a possível interferência dos hábitos alimentares das crianças nesta condição clínica de saúde. Os critérios foram avaliados por três medidas antropométricas: peso, idade e estatura, utilizando-se a referência antropométrica do WHO/MS, e o diagnóstico da anemia, que foi realizado em duas etapas: 1) coleta de hemoglobina de polpa digital, 2) por determinação da concentração de hemoglobina, concentração de ferro sérico e ferritina sérica. Trata-se de um estudo qualitativo e quantitativo de natureza descritiva epidemiológica, realizado na Estratégia de Saúde da Família (ESF) na Ilha do Combu com as comunidades igarapé Combu e igarapé Piriquitaquara, realizado no período de outubro de 2018 a fevereiro de 2019, e incluiu 153 crianças. A prevalência de anemia ferropriva encontrada foi de apenas 10%, sendo que a classificação dos anêmicos ficou entre leve (Hb=9,5g/dl) e moderada (Hb=7,2g/dl), e nenhum caso de anemia grave (Hb < 7g/dl) nem muito grave (Hb <4g/dl). Ressalta-se que 44% das crianças avaliadas recebiam suplementação na Unidade Básica de Saúde, com sais de ferro no momento da pesquisa, o que pode justificar a baixa incidência de casos de anemia nas crianças pesquisadas.
