To investigate socio-economic differences in changes in fruit and vegetable intake between 2004 and 2011 and explore the mediating role of financial barriers in this change.
Respondents completed a self-reported questionnaire in 2004 and 2011, including questions on fruit and vegetable intake (frequency per week), indicators of socio-economic position (education, income) and perceived financial barriers (fruits/vegetables are expensive, financial distress). Associations were analysed using ordinal logistic regression. The mediating role of financial barriers in the association between socio-economic position and change in fruit and vegetable intake was studied with the Baron and Kenny approach.
Longitudinal GLOBE study.
A total of 2978 Dutch adults aged 25-75 years.
Respondents with the lowest income in 2004 were more likely to report a decrease in intake of cooked vegetables (P-trend<0·001) and raw vegetables (P-trend<0·001) between 2004 and 2011, compared with those with the highest income level. Respondents with the lowest education level in 2004 were more likely to report a decrease in intake of fruits (P-trend=0·021), cooked vegetables (P-trend=0·033), raw vegetables (P-trend<0·001) and fruit juice (P-trend=0·027) between 2004 and 2011, compared with those with the highest education level. Financial barriers partially mediated the association between income and education and the decrease in fruit and cooked vegetable intake between 2004 and 2011.
These results show a widening of relative income and educational differences in fruit and vegetable intake between 2004 and 2011. Financial barriers explained a small part of this widening.
调查 2004 年至 2011 年间水果和蔬菜摄入量变化在社会经济方面的差异，并探讨其中经济障碍的中介作用。
受访者于 2004 年和 2011 年完成了一份自我报告问卷，其中包括水果和蔬菜摄入量（每周频率）、社会经济地位指标（教育、收入）和感知经济障碍（水果/蔬菜很贵，经济困难）的问题。使用有序逻辑回归分析关联。使用 Baron 和 Kenny 方法研究社会经济地位与水果和蔬菜摄入量变化之间关联的经济障碍的中介作用。
纵向 GLOBE 研究。
共 2978 名 25-75 岁的荷兰成年人。
2004 年收入最低的受访者报告 2004 年至 2011 年间熟食蔬菜（P 趋势<0·001）和生蔬菜（P 趋势<0·001）摄入量下降的可能性更大，而收入水平最高的受访者则不然。2004 年受教育程度最低的受访者报告 2004 年至 2011 年间水果（P 趋势=0·021）、熟食蔬菜（P 趋势=0·033）、生蔬菜（P 趋势<0·001）和果汁（P 趋势=0·027）摄入量下降的可能性更大，而受教育程度最高的受访者则不然。经济障碍部分解释了收入和教育与 2004 年至 2011 年间水果和熟食蔬菜摄入量下降之间的关联。
这些结果表明，2004 年至 2011 年间，水果和蔬菜摄入量在收入和教育方面的相对差异有所扩大。经济障碍解释了这一扩大的一小部分。
