食品安全状况可能会缓和人们对水果和蔬菜消费障碍的看法。这项研究旨在1)描述水果和蔬菜消费与消费的微障碍和中间障碍之间的关联，以及2)检验这些关联是否因食品安全状况而不同。2013年和2014年，我们对居住在加利福尼亚州奥克兰两个经济贫困社区的成年人(n=531)进行了调查。多元线性回归评估了微障碍(口味、成本、忙碌)和中间障碍(产品选择、质量和购买简易性)与水果和蔬菜消费之间的关系，来自26项饮食筛查。通过食品安全状况来检验相互作用。受访者平均每天消费2.4(标准差，1.5)份水果和蔬菜；39%的样本是食物不安全。在所有受访者中，忙于准备健康食物与水果和蔬菜摄入量减少有关(β忙碌=−0.40；95%可信区间[CI]，−0.52至−0.28)。食品安全缓和了水果和蔬菜消费与健康食品的味道、成本和感知的购买便利性之间的关系。在食品安全方面，不喜欢健康食品的味道(β味觉=−0.38；95%CI，−0.60至−0.15)和成本(β成本=−0.29；95%CI，−0.44至−0.15)与较低的水果和蔬菜消费量有关。在这两组人中，Mezzobarrier与消费都没有显著的关联。感知到的时间限制影响了水果和蔬菜的消费。口味和成本影响了安全食品中水果和蔬菜的消费，在解释描述饮食摄入量的分析和设计与饮食相关的干预措施时，可能需要考虑这些因素。
Food security status may moderate how people perceive barriers to fruit and vegetable consumption. This study aimed to 1) describe the association between fruit and vegetable consumption and microbarriers and mezzobarriers to consumption, and 2) test whether these associations differ by food security status. We surveyed adults (n = 531) living in 2 economically deprived communities in Oakland, California, in 2013 and 2014. Multivariate linear regression assessed associations between microbarriers (taste, cost, busyness) and mezzobarriers (produce selection, quality, and purchase ease) and fruit and vegetable consumption, derived from a 26-item dietary screener. Interactions were tested by food security status. Respondents consumed a mean 2.4 (standard deviation, 1.5) servings of fruits and vegetables daily; 39% of the sample was food insecure. Being too busy to prepare healthy foods was associated with reduced fruit and vegetable consumption (βbusyness = −0.40; 95% confidence interval [CI], −0.52 to −0.28) among all respondents. Food security moderated the relationship between fruit and vegetable consumption and taste, cost, and perceived ease of purchase of healthy foods. Among the food secure, disliking healthy food taste (βtaste = −0.38; 95% CI, −0.60 to −0.15) and cost (βcost = −0.29; 95% CI, −0.44 to −0.15) concerns were associated with lower consumptions of fruits and vegetables. Mezzobarriers were not significantly associated with consumption in either group. Perceived time constraints influenced fruit and vegetable consumption. Taste and cost influenced fruit and vegetable consumption among the food secure and may need to be considered when interpreting analyses that describe dietary intake and designing diet-related interventions.
