Item Acesso aberto (Open Access) Associação entre excesso de peso e consumo de feijão em adultos(2010-04) SILVA, Sara Araújo da; SANTOS, Priscilla de Nazaré Silva dos; MOURA, Erly Catarina deOBJECTIVE: The objective of this study was to assess the association between overweight and intake of beans in adults. METHODS: The study population was 2,352 adults (>18 years of age) living in Belém (PA), Brazil, in 2005. Sampling was done by randomly selecting households with a telephone landline and then selecting an adult in the household. The dependent variable was overweight, the explanatory variable was intake of beans and the confounding variables were age, education level, marital status, leisure-time physical activity and risky food habits. The data were analyzed by the chi-square test and logistic regression. RESULTS: A total of 2,352 individuals were assessed where 39.8% were males. The prevalence of overweight was higher in men (49.3%) than in women (34.0%, p<0.001). Overweight was directly associated with age in both genders and with education level in men. In women, overweight was inversely associated with education level. The food behavior variable that best associated with overweight was intake of beans. After adjustment for the other variables, the risk of overweight was approximately 1.4 times greater in men who ate beans less than five times per week, but the inverse was true for women. CONCLUSION: The data show that better controlled studies are needed to understand the association between intake of beans and excess weight.Item Acesso aberto (Open Access) Impacto da farinha de mandioca fortificada com ferro aminoácido quelato no nível de hemoglobina de pré-escolares(Universidade Federal do Pará, 2003-03) TUMA, Rahilda Conceição Ferreira Brito; YUYAMA, Lucia Kiyoko Ozaki; AGUIAR, Jaime Paiva Lopes; MARQUES, Hedylamar OliveiraObjective: The impact of the cassava flour fortified with iron amino acid chelate was evaluated in 80 pre-scholars of a Philanthropic Unit of Manaus, state of Amazonas, randomly distributed in four groups of 20 children each, for a period of 120 days. Methods: Cassava flour was used without fortification (group zero) or fortified with 1, 2 and 3mg of Fe/day, corresponding respectively to 5, 10 and 15g of flour/day, which were given to the children at lunch time on weekdays. The equivalent amount was previously distributed to their families for flour intake also during the weekends. In the beginning and at the end of the experiment the children’s nutritional status was evaluated, being adopted the cutoff point <-2 Z-scores as a discriminating limit between eutrophy/ malnutrition, in agreement with the World Health Organization criteria, as well as being established as a cutoff point for the occurrence of iron deficiency anemia a hemoglobin rate of less than 11g/dL. Results: At the end of this study, children recovered from chronic malnutrition, and a significant increase (p <5%) of the hemoglobin rates, independently of iron concentration, from 11.4±0.9g/dL to 12.2±0.8g/dL, was observed in all individuals. The formerly anemic children who received cassava flour fortified with 2mg of Fe/day were fully recovered at the end of the research, demonstrating a good performance of this group in relation to the others. Conclusion: A double-blind study is suggested for the consolidation of the recommendation of cassava flour fortified with iron in the prevention of iron deficiency anemia in pre-scholars of the Amazon region.Item Acesso aberto (Open Access) Perfil de utilização de repositores protéicos nas academias de Belém, Pará(Universidade Federal do Pará, 1999-04) ARAÚJO, Ana Cláudia Matos de; SOARES, Yone de Nazareth GonçalvesThe presente study was carried out in the first semester of 1996, aiming to evaluate users of academies in Belém, Pará, Brazil. Beyond vast bibliographic research about the energetic and proteic metabolism, sportsmen’s nutritional necessities and supplementation with protein and amino acids, a field research was carried out with the purpose of tracing the profile of utilization of nutritional suplements with emphasis on protein and amino acid products, considering sex, age and period of physical activity practice. The research involved a sample of 18 academies and 388 interviewees; 103 of then (27%) used some kind of supplementation and 45 of these (44%) used protein supplements. Among the justifications given for the option of using the supplementation, the “professional indication” stood out from the others. Comparison with technical list existing in these units, in which only 4 of the 18 academies included in the sample had nutritionists or doctors, suggests that the utilization of these products by physical activities practitioners may be inadequate.
