title: Trends of socioeconomic differences in daily vegetable consumption, 1979-2002.
abstract: BACKGROUND
  Studies from different time periods have shown that consumption of vegetables is more common in higher socioeconomic groups and among women. However, there are only few studies of changes of socioeconomic differences in vegetable consumption over time. Our aim was to determine whether socioeconomic differences, measured by educational level and household income, in daily vegetable consumption have increased, decreased or been stable over the last two decades among Finnish men and women.
  
  
  METHODS
  Data on daily consumption of fresh vegetables were derived from repeated annual cross-sectional surveys performed among representative samples of Finnish working aged (15-64 years) population. Data from the years 1979-2002 were linked with data on education and household income from Statistics Finland. Those under 25 years and all students were excluded, giving a total of 69 383 respondents. The main analyses were conducted with logistic regression.
  
  
  RESULTS
  Daily consumption of fresh vegetables became overall more prevalent during the study period. Daily consumption of fresh vegetables was more common among those with higher education and higher income during the whole study period. Both educational level and household income differences in daily vegetable consumption slightly narrowed since 1979 among men and women.
  
  
  CONCLUSIONS
  Women with high socioeconomic position have been initial trend setters, but the prevalence of daily consumers of vegetables in these groups has not increased since the early 1990s. The prevalence of daily consumption of fresh vegetables has increased more in lower educational and income groups during the 1980s and 1990s along with narrowing socioeconomic differences.
