- ItemAcesso aberto (Open Access)Consumo de frutas e hortaliças por adultos em Ribeirão Preto, SP(Faculdade de Saúde Pública da Universidade de São Paulo, 2010-08-01) Mondini, Lenise [UNIFESP]; Moraes, Suzana Alves de; Freitas, Isabel Cristina Martins de; Gimeno, Suely Godoy Agostinho [UNIFESP]; Secretaria de Agricultura e Abastecimento do Estado de São Paulo Instituto de Economia Agrícola; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: To assess fruit and vegetable intake by adults and identify sociodemographic and life style variables associated with this intake. METHODS: A population-based cross-sectional study was performed in the urban area of the city of Ribeirão Preto, Southeastern Brazil, in 2006. Sample was selected using three-stage cluster sampling, with census tracts as primary units. Sample was comprised of 930 participants aged 30 years and more and the design effect was considered in data analysis. Fruit and vegetable intake was based on a semi-quantitative food frequency questionnaire, using mean scores of frequency of fruit and vegetable intake, daily intake and minimum intake of such foods as indicators. The independent variables analyzed were as follows: age group, marital status, level of education, per capita household income, nutritional status, smoking and physical activity. Mean scores of frequency of intake were estimated by point and 95% confidence intervals. Prevalence ratios were also estimated by point and 95% confidence intervals to analyze association, using Poisson regression. Linear trend tests were applied, adopting a 5% confidence level. RESULTS: Only 24% of men and 38% of women met the minimum recommendation for fruit and vegetable intake; there was a positive association with age and per capita income. Women with a higher level of education and men who lived with a female partner consumed more fruits and vegetables than others. Physical activity, smoking and nutritional status were not associated with the minimum recommended fruit and vegetable intake. CONCLUSIONS: Socioeconomic factors have an important influence on fruit and vegetable intake and, as these are subject to intervention, they can contribute to the adoption of healthy eating habits.
- ItemAcesso aberto (Open Access)Consumption of vegetables and their relation with ultra-processed foods in Brazil(Revista de Saude Publica, 2018) Canella, Daniela Silva; Louzada, Maria Laura da Costa [UNIFESP]; Claro, Rafael Moreira; Costa, Janaina Calu [UNIFESP]; Bandoni, Daniel Henrique [UNIFESP]; Levy, Renata Bertazzi; Martins, Ana Paula BortolettoOBJECTIVE: To characterize the household purchase and the individual consumption of vegetables in Brazil and to analyze their relation with the consumption of ultra-processed foods. METHODS: We have used data on the purchase of food for household consumption and individual consumption from the 2008-2009 Brazilian Household Budget Survey. The Brazilian Household Budget Survey studied the purchase of food of 55,970 households and the food consumption of 34,003 individuals aged 10 years and over. The foods of interest in this study were vegetables (excluding roots and tubers) and ultra-processed foods. We have described the amount of vegetables (grams) purchased and consumed by all Brazilians and according to the quintiles of caloric intake of ultra-processed food. To this end, we have calculated the crude and predicted values obtained by regression models adjusted for sociodemographic variables. We have analyzed the most commonly purchased types of vegetables (% in the total amount) and, in relation to individual food consumption, the variety of vegetables consumed (absolute number), the participation (%) of the types of culinary preparations based on vegetables, and the time of consumption. RESULTS: The adjusted mean household purchase of vegetables was 42.9 g/per capita/day. The adjusted mean individual consumption was 46.1 g. There was an inverse relation between household purchase and individual consumption of vegetables and ultra-processed foods. Ten types of vegetables account for more than 80% of the total amount usually purchased. The variety consumed was, on average, 1.08 type/per capita/day. Approximately 60% of the vegetables were eaten raw, and the amount consumed at lunch was twice that consumed at dinner
- ItemAcesso aberto (Open Access)Relative validity of a food-frequency questionnaire developed to assess food intake of schoolchildren living in the Brazilian Western Amazon(Escola Nacional de Saúde Pública Sergio Arouca, Fundação Oswaldo Cruz, 2011-11-01) Scagliusi, Fernanda Baeza [UNIFESP]; Garcia, Mariana Tarricone; Indiani, Ana Luiza Coutinho; Cardoso, Marly Augusto; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)This study aimed to assess the relative validity of a food frequency questionnaire (FFQ) developed to assess food intake of schoolchildren from the Brazilian Western Amazon. The dietary intakes of 61 schoolchildren, aged between six and nine 9 years, were measured using two 24-hour dietary recalls and one FFQ, conducted with the children's, mother or guardians. Validity of the FFQ compared to the mean of the two dietary recalls was assessed using Pearson's correlation coefficient adjusted for attenuation and energy intake, Bland & Altman plots and evaluation of agreement levels between the two assessment methods. Energy-adjusted and deattenuated correlation coefficients ranged from -0.03 for vitamin C, to 0.93 for calcium. The mean coefficient was 0.46. The mean proportion of subjects classified within one quintile by the two methods was 66%. The Bland & Altman plots indicated good agreement for almost all nutrients, with a mean limit of agreement of 108%. These results indicate that, although there was a lack of accuracy for certain nutrients, such as vitamins A and C, the FFQ ensures reliable estimates of intake of most nutrients.
