Determinants of fruit and vegetable consumption, including affordability and attitudes, have been poorly investigated, especially in European deprived populations. Our objective was to analyze various determinants of low consumption of fruits and vegetables in disadvantaged participants. Our participants were randomized into 2 groups, 1 which received nutritional advice alone and 1 that also received vouchers that were exchangeable for fruits and vegetables during a 12-mo period. Socioeconomic characteristics, food insufficiency, affordability, and motivation for eating fruits and vegetables were assessed. A short FFQ was administered. Determinants of consumption of <1 fruit or vegetable/d were analyzed using multivariate logistic regression. A total of 295 participants were included (mean age 44.8 y; 133 men, 162 women). At baseline, mean daily consumption of fruits and vegetables was 2.13 +/- 1.57 times/d. Nearly 30% of the sample did not eat fruits and vegetables every day. Determinants of low fruit and vegetable consumption were: age younger than 55 y, education level lower than tertiary, and absence of financial means for buying fruits and vegetables daily. Other determinants were affordability (whether fruits and vegetables are affordable, lack of money in preventing healthy diet) and attitudes (whether one's own diet is healthy, whether or not fruits and vegetables improve health, whether eating fruits and vegetables is a pleasure). Thus, determinants of inadequate consumption of fruits and vegetables in this deprived French population are numerous. The impact of financial difficulties is crucial, as is the perception of affordability of fruits and vegetables.
水果和蔬菜消费的决定因素,包括可负担性和态度,研究得很差,特别是在欧洲贫困人群中。我们的目的是分析贫困参与者中水果和蔬菜低消费的各种决定因素。我们的参与者被随机分为 2 组,一组仅接受营养建议,另一组在 12 个月内还收到可兑换水果和蔬菜的代金券。评估了社会经济特征、食物不足、可负担性和食用水果和蔬菜的动机。进行了简短的食物频率问卷(FFQ)调查。使用多变量逻辑回归分析了 <1 份水果或蔬菜/天的消费决定因素。共纳入 295 名参与者(平均年龄 44.8 岁;133 名男性,162 名女性)。在基线时,水果和蔬菜的平均每日摄入量为 2.13 +/- 1.57 次/天。近 30%的样本没有每天吃水果和蔬菜。低水果和蔬菜消费的决定因素包括:年龄小于 55 岁、教育水平低于高等教育和没有每天购买水果和蔬菜的经济手段。其他决定因素包括可负担性(水果和蔬菜是否负担得起,缺乏资金来维持健康饮食)和态度(自己的饮食是否健康,水果和蔬菜是否改善健康,食用水果和蔬菜是否是一种乐趣)。因此,在这个贫困的法国人群中,水果和蔬菜摄入不足的决定因素很多。经济困难的影响至关重要,对水果和蔬菜的可负担性的看法也是如此。
