    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 de
    OBJECTIVE: 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.

    Associação entre hipertensão arterial e excesso de peso em adultos, Belém, Pará, 2005
    (2008-08) BORGES, Hilma Paixão; CRUZ, Nilma do Carmo; MOURA, Erly Catarina de
    BACKGROUND: Hypertension is a major public health issue affecting 20 to 25% of the global population of adults, and 12 to 35 % of Brazilians. OBJECTIVE: To evaluate the association between hypertension and overweight. METHODS: A cross-sectional study was conducted in 2005 with a probabilistic sampling of the population >18 years of age in Belém, capital of the state of Pará, in the Northern region of Brazil, using the telephone surveillance system for chronic diseases (SIMTEL). The dependent variable was hypertension, the explanatory variable was overweight and the confounding variables were age, level of education and lifestyle characteristics. The variables associated with hypertension were run through the regression logistic model and odds ratios were calculated for each variable. RESULTS: Hypertension affected 16.2% of men and 18.3% of women, and overweight affected 49.2% of men and 34.1% of women. The prevalence of hypertension was directly associated with age and overweight in both genders. Among men, hypertension was associated with intake of vegetables and low intake of beans (similar to kidney- and pinto-type beans); as for women, hypertension was associated with marital status (widow or separated), and inversely to education level. The risk of hypertension increased directly with weight for both genders (p<0.001), and it was 6.33 times higher among obese men and 3.33 among obese women as compared to normal-weight subjects. CONCLUSION: Overweight was associated with hypertension. However, variables such as age, education, and food consumption interfere in this relationship, creating circumstances favorable to reducing or increasing that risk.

    Validação de indicadores do consumo de alimentos e bebidas obtidos por inquérito telefônico em Belém, Pará, Brasil
    (2010-12) NEVES, Alice Cristina Medeiros das; GONZAGA, Lidyane Andrea Amaral; MARTENS, Irland Barroncas Gonzaga; MOURA, Erly Catarina de
    The aim of this study was to evaluate the relative validity of indicators of food and beverage intake obtained from the telephone interview surveillance system (VIGITEL). A random sample (n = 100) was evaluated from the total sample of approximately two thousand adults studied by the system in 2009 in Belém, Pará State, Brazil. The indicators were protective factors (adequate consumption of fruit, vegetables, and leafy vegetables) and risk factors (consumption of saturated fat, soft drinks, and alcoholic beverages) for chronic non-communicable diseases. The telephone interview results were compared with those of three 24-hour recalls (reference standard). The reference standard showed underestimation in the indicators' frequency, except for soft drinks and alcoholic beverages. The mean consumption frequencies were generally higher in the exposed group interviewed by the VIGITEL system. We cannot conclude that the VIGITEL system is not a good indicator of consumption, since the reference standard also shows limitations. Nevertheless, its use as a surveillance tool in Brazil is justifiable.
