title: Fruit and vegetable intake by adults in Ribeirão Preto, Southeastern Brazil.
abstract: 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.
