Evidence supports the relationship between fruit and vegetable consumption (FVC) and risk reduction for several illness conditions, even for older adults. Thus, we examined the effects of motivational interviewing (MI) on FVC in adults with a mean age ≥60. We chose MI because of its growing popularity as an effective behavior change strategy and because the person-centered MI principles are a good fit for older adults. We searched 10 electronic databases, several journals, and unpublished and fugitive literature. We retrieved seven primary studies, providing nine comparisons, with 1,978 participants. The overall MI effect size (ES) was .221 ( p = .002). When the percentage of women was greater, ES was lower; when interventionists had more training, ES was higher; and when sessions were longer, ES was stronger. Future researchers might test longer sessions with trained interventionists and examine gender differences. Practitioners should be well trained and offer sessions that are 30 to 40 min in length.
有证据支持食用水果和蔬菜（FVC）与降低多种疾病风险之间的关系，即使对于老年人也是如此。因此，我们研究了动机性访谈（MI）对平均年龄≥60岁成年人的FVC的影响。我们选择MI是因为它作为一种有效的行为改变策略越来越受欢迎，并且以人为主的MI原则很适合老年人。我们检索了10个电子数据库、几本期刊以及未发表和难以获取的文献。我们检索到7项主要研究，提供了9组比较，涉及1978名参与者。MI的总体效应量（ES）为0.221（p = 0.002）。女性比例越高，ES越低；干预者接受的培训越多，ES越高；疗程越长，效果越强。未来的研究人员可以测试由训练有素的干预者进行的更长疗程，并研究性别差异。从业者应该接受良好的培训，并提供时长为30至40分钟的疗程。
