“…10 The FFQ currently applied 34 has been used in previous studies. [36][37][38] The good reproducibility for associations currently observed by applying FFQ and PCA was also identified by another author. 39 In fact, FFQ can be applied in epidemiological studies, since it is able to associate the frequency of intake of certain dietary factors with variables of interest.…”

Objective: dietary pattern evaluation is often used in order to determine wheter a diet is healthy, as well as to predict the onset of diseases. This study aimed to identify dietary patterns, and to examine their associations with general (body mass index) and central (waist circumference and waist-to-hip ratio) obesity in community-living elderly in a Brazilian city. Methods: this cross-sectional study included 126 elderly subjects aged 60 or older (57.1% females and mean age 74.2 ± 6.46 years). Anthropometric variables, weight, height, waist (WC) and hip (HC) circumferences, were measured. Body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Answers to a Food Frequency Questionnaire were interpreted by Principal Component Analysis in order to identify dietary patterns. Results: five dietary patterns were identified and named as prudent (fruit, vegetables and meat), sweets and fats (pastries, sugary foods, fatty foods, whole milk), typical Brazilian (fried eggs, cooked beans, beef, candy, string beans, fried cassava), Mediterranean (fruit, vegetables, olive oil and nuts) and traditional meal (rice and beans). Moderate and high adherences to the Mediterranean pattern were protective factors to general and central obesity (WHR). High adherence to prudent was also protective to central obesity (WC). Conclusion: adherences to the dietary patterns prudent and Mediterranean were protective factors to general and central obesity in elderly.

“…The Quantitative Food Frequency Questionnaire (QFFQ) used in the HIM study in Brazil was developed based on the dietary intake cited on the 24HR of 708 men in the population-based survey Inquéritos de Saúde de São Paulo (ISA-SP, Health Survey of São Paulo). The full description of the QFFQ development and validation is described in previous studies [10,11]. The participants in Brazil have reported the frequency of their consumption of the 54 food items (0-10 times a day, week, month, or year) over the past year and the size of the consumed portion (small, medium, large, and extra-large).…”

“…The FFQ used in the cohort study entitled "Natural History of HPV Infection In Men" (HIM study) in Brazil was developed by Fisberg et al [11] based on the food intake of a representative sample of men in the city of São Paulo. In addition, validation [12] and calibration [10] studies were conducted, and the performance of the method was assessed when standard portions were replaced by portions obtained in a sub-sample of the Brazilian cohort [13], once portion determination is considered one of the main errors of dietary intake assessment [14,15].…”

Objective This study aimed to compare dietary intake estimates using two different methodological approaches: use of new portions obtained with the 24-Hour Diet Recall, which was applied in the current study population, and the application of calibration equations, which were estimated using the same 24h-recalls. Methods Calibration equations were estimated using linear regression. The medians and confidence intervals of energy and nutrient intakes were assessed using all the approaches. The U Mann Whitney test was applied to verify differences among dietary intakes obtained with the 24 Hour Recall and Food Frequency Questionnaire-based methods. The correlation between different measures was assessed with Spearman coefficient. Weighted Kappa was used to verify the capability of the Food Frequency Questionnaire -based methods to classify individuals in the same intake levels of the 24 Hour Recall. Results Nine of the eleven components that were analyzed using the Food Frequency Questionnaire with standard portions and calibrated had medians significantly different from those obtained using the 24 Hour Recall; only the measurements of vitamin E and energy were statistically equal. For the Food Frequency Questionnaire with 24 Hour Recall portions, only the medians of vitamin D and B12 did not significantly differ from the 24 Hour Recall medians. Finally, for the Food Frequency Questionnaire with 24 Hour Recall portions and calibrated, all components, except folate and iron, had medians statistically equal to those obtained using the 24 Hour Recall. Spearman correlation coefficients were higher for the Food Frequency Questionnaire with 24 Hour Recall portions calibrated for all the assessed components, and the values ranged from 0.27 (total fat) to 0.57 (iron). Higher Kappa correlation coefficients were found for the Food Frequency Questionnaire 24 Hour Recall portions calibrated. Conclusion Calibrated FFQ with portions estimated from the own target population obtained better estimates of dietary intake, with values considerably more similar to those obtained with the reference method.

Background: HPV infections are the most common among sexually transmitted diseases. Although most frequently transitory, persistent oncogenic-type HPV infection may progress to a precursor lesion and, if not correctly treated, to cancer. The dissemination of HPV tends to be universal in sexually active individuals. Men, besides being in risk to cancer, in special penile and anal cancer, can be the spreader of this virus to women, contributing to the infection, and hence the cervical cancer. However, little is known about this infection in men. Some studies discuss the possible relation between diet and the risk of HPV and the role of food in persistent infections. Food and nutrients could influence carcinogenesis process by affecting nutritional status, susceptibility to infection and by acting in the probability of infection turning persistent and progressing to neoplastic lesions, besides altering DNA repair and stability.Objective: Investigate the relation of selected nutrients and HPV persistent infection in men of São Paulo, Brazil. Methods: The study population consisted of 1,248 men from the Brazilian cohort of HIM study, aged from 18 to 70 years old, whose answered a quantitative food frequency questionnaire (FFQ) in the baseline. The FFQ was developed and validated for the study population and afterwards calibrated and energy-adjusted. The U Mann-Whitney test was used to assess differences in the medians of nutrient intake between men with persistent and non-persistent infection. The association of dietary intake and persistent HPV infection was assessed in multivariate logistic models. Two independent multivariate logistic regression models were developed, one for oncogenic HPV persistent infection and other for nononcogenic HPV persistent infection. By treating categorical nutrient variables as continuous, it was possible to perform tests for trends. INTRODUÇÃOEntre as doenças sexualmente transmissíveis (DST), as infecções por papilomavírus humano (HPV) são as mais comuns no mundo (TROITTIER, 2006;MINISTÉRIO DA SAÚDE, 2013). Mesmo que muito frequentes, são, em geral, transitórias, e se resolvem espontaneamente pelo sistema imunológico na maioria dos casos (STANLEY, 2008, WILLIAMS et al., 2011 WHO, 2014 WILLIAMS et al., 2011; IARC, 2012 (MINISTÉRIO DA SAÚDE, 2015b; INCA, 2015) Estima-se que entre 25% e 50% da população feminina e por volta de 50% da população masculina mundial tenha alguma infecção por HPV (INCA, 2015), e que cerca de 80% das pessoas adquiram algum tipo de HPV em 15 algum momento da vida (INCT-HPV, 2013). No Brasil, acredita-se que existam cerca de 10 milhões de pessoas contaminadas pelo HPV (GIRALDO et al., 2008; INCT-HPV, 2013) e, a cada ano, 685,4 mil novas pessoas são infectadas por algum tipo do vírus (BRASIL, 2014).A disseminação do HPV tende a ser universal entre os indivíduos sexualmente ativos, sendo que o homem, além do risco de câncer anal, peniano e da orofaringe, pode ser um importante fator propagador desse vírus entre as mulheres, contribuindo para a infecção...
