To assess the response of low consumers of fruit and vegetables to a nutrition education intervention programme, data were collected from 104 adults on attitudinal variables related to 'eating more fruit, vegetables and vegetable dishes'. Questionnaires (based on the theory of planned behaviour) assessing perceived barriers to increasing fruit and vegetable consumption were administered before an action-orientated intervention programme and at the end of the intervention period (8 weeks). Questionnaire scores for belief-evaluations in the intervention groups pre- and post-study indicated that support of family and friends, food costs, time constraints and shopping practicalities (in order to increase intake of fruit, vegetable and vegetable dishes) were barriers to greater consumption of these foodstuffs. Perceived situational barriers to increasing intakes of fruits and vegetables were: limited availability of vegetables, salads and fruit at work canteens, take-aways, friends' houses and at work generally. Following the intervention the number of visits to the shops was perceived as a greater barrier for increasing intakes of fruit and vegetables. Perceived practical opportunities for increasing intakes high-lighted drinking fruit juice, taking fruit as a dessert, having fruit as a between-meal snack and eating two portions of vegetables with a meal. About two-thirds of intervention subjects achieved the recommended fruit and vegetable target, but it is concluded that practical issues and situational barriers need to be addressed for the success of future public health campaigns.
为评估果蔬低摄入量人群对营养教育干预计划的反应，收集了104名成年人与“增加水果、蔬菜和蔬菜菜肴摄入量”相关的态度变量数据。在一项以行动为导向的干预计划实施前及干预期结束时（8周），发放了基于计划行为理论的问卷，以评估增加果蔬消费的感知障碍。研究前后干预组问卷中信念评估得分表明，家人和朋友的支持、食品成本、时间限制和购物便利性（为增加水果、蔬菜和蔬菜菜肴的摄入量）是增加这些食品消费的障碍。增加水果和蔬菜摄入量的感知情境障碍包括：工作食堂、外卖店、朋友家以及工作场所普遍存在蔬菜、沙拉和水果供应有限的情况。干预后，去商店购物的次数被认为是增加水果和蔬菜摄入量的更大障碍。增加摄入量的感知实际机会包括：喝果汁、把水果作为甜点、把水果作为餐间零食以及每餐吃两份蔬菜。约三分之二的干预对象达到了推荐的果蔬摄入量目标，但得出的结论是，为使未来的公共卫生运动取得成功，需要解决实际问题和情境障碍。
