Making Effective Nutritional Choices

Dr. Christine Cole Johnson (HFHS) led the development and evaluation of an individually tailored, Web-based program to promote daily fruit and vegetable (F&V) consumption. Its efficacy was tested in a randomized trial of five HMOs. The online intervention was shown to be effective in the diverse sample of healthy adults who enrolled. All three intervention arms (untailored and tailored Web program and tailored Web program plus email support) showed early and sustained increases of more than two F&V servings per day. The untailored Web program arm was least effective. Those participating online at a higher rate had more gain in F&V servings, the retention rate was high, and reported satisfaction with the online program overall was high. Analyses exploring the effects of additional variables on dietary behaviors are ongoing.
