Improving dietary intakes is a key public health target. Perceived barriers to healthy eating (PBHE) are an important component of the Health Belief Model which aims to understand why individuals do not adopt preventive health measures. This study investigates the relationship between PBHE and reported fruit and vegetable (F&V) consumption.
Data from the Scottish Health Survey 2008-11 (n = 8319) for PBHE and self-reported F&V consumption were used in Probit regression models to test the association between meeting the 400 g per day F&V recommendation and PBHE.
Regression models show women who reported a lack of cooking skills were 10.4% less likely to meet the F&V recommendations (P = 0.001). Not liking the taste of healthy foods or finding them too boring (10.2%, P = 0.022), preparation time (5.6%, P = 0.020) or willpower (3.0%, P = 0.021) were also significant. For men, reporting not liking the taste of healthy foods or finding them too boring (6.8%, P = 0.02) was the only significant result. Price, a commonly reported PBHE, was not significantly associated with F&V consumption.
Not all commonly reported perceived barriers to healthy eating are significantly associated with meeting the recommended F&V intake.
改善饮食摄入是一项关键的公共卫生目标。感知到的健康饮食障碍（PBHE）是健康信念模型的一个重要组成部分，该模型旨在理解个体为何不采取预防性健康措施。本研究调查了PBHE与报告的水果和蔬菜（F&V）摄入量之间的关系。
使用2008 - 2011年苏格兰健康调查（n = 8319）中关于PBHE和自我报告的F&V摄入量的数据，通过Probit回归模型来检验达到每天400克F&V推荐量与PBHE之间的关联。
回归模型显示，报告缺乏烹饪技能的女性达到F&V推荐量的可能性降低了10.4%（P = 0.001）。不喜欢健康食品的味道或觉得它们太无趣（10.2%，P = 0.022）、准备时间（5.6%，P = 0.020）或意志力（3.0%，P = 0.021）也具有显著影响。对于男性，报告不喜欢健康食品的味道或觉得它们太无趣（6.8%，P = 0.02）是唯一显著的结果。价格，一种常见的PBHE，与F&V摄入量没有显著关联。
并非所有常见的感知到的健康饮食障碍都与达到推荐的F&V摄入量显著相关。
