这项研究调查了家庭收入与新鲜水果和蔬菜消费的关系是否因教育水平而异。数据来自2000-2002年期间进行的邮件调查中的40- 60岁的雇员的城市赫尔辛基（n = 8960，响应率67%）。教育分为三个级别，家庭收入分为四分位数，按家庭规模加权。结果是每天至少食用两次新鲜水果和蔬菜（58%的女性和33%的男性）。采用β-二项式回归分析。在妇女中，较高的收入导致所有教育水平的水果和蔬菜消费量同样较高，即在低、中、高教育水平的妇女中相似。在男子中，这一模式在其他方面类似;然而，受过中等教育的男子与受教育程度低的男子不同。我们的结论是，健康食品的绝对成本很可能对所有收入群体都有影响。欧洲临床营养学杂志（2010）64，324-327; doi：10.1038/ejcn.2009.155; 2010年1月20日在线发表
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.
