Increasing fruit and vegetable consumption is a goal for the U.K. Therefore, the effectiveness of a fruit and vegetable voucher scheme coupled with key 'five-a-day' consumption messages as a brief intervention in primary care consultations was assessed in the present study.
One thousand one hundred and eighty-eight vouchers as a prescription for fruits and vegetables were routinely distributed to patients attending a primary healthcare centre in a deprived area, and 124 volunteer patients routinely attending the centre were included. Telephone-based questionnaires were used to examine changes in consumption over the short and medium term. Other key aspects assessed in the evaluation related to fruit and vegetable purchasing behaviour, knowledge relating to what constitutes a portion size, the relationship between food and health, and barriers to consumption.
Although 76.2% of participants used the prescription vouchers when purchasing fruits and vegetables, a significant change in the consumption or purchasing behaviour was not observed (P > 0.05). Participants' level of knowledge relating to the number of portions recommended and the portion size of different fruits and vegetables showed a moderate increase from baseline over the short and medium term. The primary barriers to fruit and vegetable consumption were reported as 'the quality of fresh fruits and vegetables' and 'the money available to spend on food'.
The use of 'the fruit and vegetable on prescription' scheme was an effective method of engaging participants in improving awareness of key diet-related health messages. However, further intervention is required to produce a significant impact on the actual behaviour change.
增加水果和蔬菜的摄入量是英国的一个目标。因此，在本研究中评估了一项水果和蔬菜代金券计划以及关键的“每日五蔬果”消费信息作为初级保健咨询中的简短干预措施的有效性。
向一个贫困地区的初级保健中心就诊的患者常规发放1188张水果和蔬菜代金券作为处方，纳入了124名经常到该中心就诊的志愿患者。通过电话问卷来调查短期和中期的消费变化。评估中的其他关键方面涉及水果和蔬菜的购买行为、与一份量构成相关的知识、食物与健康的关系以及消费障碍。
尽管76.2%的参与者在购买水果和蔬菜时使用了处方代金券，但未观察到消费或购买行为有显著变化（P>0.05）。参与者关于推荐份数以及不同水果和蔬菜一份量大小的知识水平在短期和中期从基线有适度提高。报告的水果和蔬菜消费的主要障碍是“新鲜水果和蔬菜的质量”以及“可用于购买食物的钱”。
“处方水果和蔬菜”计划的使用是促使参与者提高对关键饮食相关健康信息认识的有效方法。然而，需要进一步干预以对实际行为改变产生显著影响。
