This study examined whether the association of household income with fresh fruit and vegetable consumption varies by the level of education. Data were derived from mail surveys carried out during 2000-2002 among 40- to 60-year-old employees of the City of Helsinki (n=8960, response rate 67%). Education was categorized into three levels, and the household income was divided into quartiles weighted by household size. The outcome was consumption of fresh fruit and vegetables at least twice a day (58% among women and 33% among men). Beta-binomial regression analysis was used. Among women, higher income resulted in equally higher consumption of fruit and vegetables at all educational levels, that is, similar among those with low, intermediate and high education. Among men, the pattern was otherwise similar; however, men with intermediate education differed from those with low education. We conclude that the absolute cost of healthy food is likely to have a role across all income groups.
本研究旨在探讨家庭收入与新鲜水果和蔬菜消费之间的关联是否因受教育程度而异。数据来源于 2000-2002 年期间对赫尔辛基市 40 至 60 岁员工进行的邮件调查（n=8960，回应率为 67%）。教育程度分为三个层次，家庭收入按家庭规模加权分为四个四分位数。结果是每天至少食用两次新鲜水果和蔬菜（女性占 58%，男性占 33%）。采用贝塔二项式回归分析。在女性中，高收入与所有教育程度的水果和蔬菜消费同样较高有关，即无论教育程度高低，情况都相似。在男性中，模式大致相同；然而，具有中等教育程度的男性与具有低等教育程度的男性不同。我们的结论是，健康食品的绝对成本可能在所有收入群体中都发挥作用。
