Background: Current recommendations for chronic disease prevention include increasing consumption of fruits and vegetables. We tested the effectiveness of a single 15-minute interaction with a CD-ROM program to improve fruit and vegetable intake. Methods: Low-income African American and NonHispanic White women (n=481, mean age 50.2 years) participated in a three-arm randomized controlled study. Subjects were randomized to receive one of three intervention conditions: 1) the Little by Little CD-ROM plus two phone reminders over the following two months; 2) the Little by Little CD-ROM without reminder calls; 3) a stress-reduction CD-ROM. Subjects completed baseline assessments of knowledge, Stage of Change, and dietary intake, and follow-up assessments two months later. Fruit and vegetable intake was assessed using a modified 24-hour recall of all fruits, vegetables and juices consumed by the respondent, based on the California Dietary Practices Survey instrument. Results: Controlling for baseline fruit/vegetable intake, both Little by Little treatment groups had significantly greater increase in fruits and vegetables compared with the control group: The intervention group that included reminder calls had an 86% increase over that experienced by the control group (an increase of 1.32 occurrences per day, p=0.016). The intervention group without reminder calls had a 69% increase, 1.20 occurrences, p=0.052 compared with controls. The two intervention groups were not statistically significantly different from one another (p=0.59). There was also significant increase in Stage of Change in intervention group #1. Conclusion: This brief intervention was effective, and may be feasible in public health and primary care settings.
