Fruit and vegetable (F&V) consumption is below recommendations, and cost may be a barrier to meeting recommendations. Limited evidence exists on individual perceptions about the cost, actual spending and consumption of F&V. This study investigated perceptions and beliefs about cost of F&V and whether this is a barrier to higher consumption.
An online survey of Australian adults (n = 2474) measured F&V consumption; expenditure on F&V and food; and perceived barriers to consumption. Multivariable logistic regression examined associations between participants' responses about cost of F&V and demographic factors, and with actual consumption and expenditure on F&V.
Cost was identified as a barrier for 29% of people not meeting recommended fruit servings and for 14% of people not meeting recommendations for vegetables. Cost was a more common barrier for those on lower incomes (fruit aOR 1.89; 95% CI 1.20-2.98 and vegetables aOR 2.94; 95% CI 1.97-4.39) and less common for older participants (fruit aOR 0.33; 95% CI 0.17-0.62 and vegetables aOR 0.31; 95% CI 0.18-0.52). There was no association between the perceived barriers and actual F&V spending. Twenty percent of participants said F&V were not affordable; 39% said cost made it difficult to buy F&V, and for 23% the cost of F&V meant they bought less than desired.
A minority reported F&V were not affordable where they shopped and that cost was a barrier to higher consumption. However, it is apparent that young adults and those on low incomes eat less than they would like because of cost. Strategies that remove financial impediments to consumption are indicated for these population sub-groups.
水果和蔬菜(F&V)的摄入量低于建议水平,成本可能是达到建议摄入量的一个障碍。关于个人对F&V成本、实际支出和消费的看法,现有证据有限。本研究调查了对F&V成本的看法和信念,以及这是否是增加消费的一个障碍。
对澳大利亚成年人(n = 2474)进行的一项在线调查测量了F&V的消费量;F&V和食品的支出;以及消费的感知障碍。多变量逻辑回归分析了参与者对F&V成本的回答与人口统计学因素之间的关联,以及与F&V的实际消费和支出之间的关联。
成本被确定为29%未达到建议水果摄入量人群和14%未达到蔬菜建议摄入量人群的一个障碍。对于低收入者来说,成本是一个更常见的障碍(水果调整后的比值比为1.89;95%置信区间为1.20 - 2.98,蔬菜调整后的比值比为2.94;95%置信区间为1.97 - 4.39),而对于老年参与者来说则不太常见(水果调整后的比值比为0.33;95%置信区间为0.17 - 0.62,蔬菜调整后的比值比为0.31;95%置信区间为0.18 - 0.52)。感知障碍与F&V的实际支出之间没有关联。20%的参与者表示F&V价格过高难以承受;39%的参与者表示成本使得购买F&V变得困难,23%的参与者表示F&V的成本意味着他们购买的量少于期望量。
少数人报告称在他们购物的地方F&V价格过高难以承受,并且成本是增加消费的一个障碍。然而,很明显,年轻人和低收入者由于成本原因摄入的量少于他们的期望量。对于这些亚人群体,需要采取消除消费经济障碍的策略。
