Purpose. To evaluate the effects of a 12-week e-mail intervention promoting physical activity and nutrition, and to describe participant use and satisfaction feedback. Design. A longitudinal, randomized trial. Setting. Five large workplaces in Alberta, Canada. Participants. One thousand forty-three participants completed all three assessments, and 1263 participants in the experimental group provided use and satisfaction feedback after receiving the 12-week intervention. Intervention. Paired physical activity and nutrition messages were e-mailed weekly to the experimental group. The control group received all messages in bulk (i.e., within a single e-mail message) at the conclusion of the intervention. Measures. Self-report measures of knowledge, cognitions, and behaviors related to physical activity and nutrition were used. Satisfaction with e-mail messages was assessed at Time 2. Analysis. Planned contrasts compared the experimental group measures at Time 3 with those reported at Time 2 and with control group measures reported at Time 3. Control group measures at Time 3 were also compared with control group measures at Time 2. Results. The small intervention effects previously reported between Time 1 and Time 2 were maintained at Time 3. Providing the e-mail messages in bulk also had a significant positive effect on many of the physical activity and nutrition variables. Conclusions. E-mail offers a promising medium for promoting health-enhancing knowledge, attitudes, and behaviors. Additional research is needed to determine optimal message dose and content.

Purpose. Determine the proportion of adults aware of Canada's Physical Activity Guide to Healthy Active Living (Guide) and its specific recommendations (objective 1); whether key demographic factors (objective 2a) and physical activity behavior (objective 2b) are associated with awareness and specific familiarity with the Guide; and if changes in awareness and specific recommendations with the Guide occurred over a 1-year period (objective 3a and 3b). Design. Random selection with computer-assisted telephone interviewing. Setting. Edmonton, Alberta, Canada. Subjects. A total of 2803 adults 18 years or older completed interviews from 4831 telephone contacts (response rate, 58.0%), and after 1 year, 1423 individuals (55%) completed interviews. Measures. Demographic, physical activity, Guide awareness. Analysis. Chi-square, analysis of variance. Results. At baseline, 27.3% were aware of the Guide, and 15.6% were familiar with the Guide's specific recommendations. Younger individuals (p = .01), women (p < .001), and those with a higher education (p < .001) were more likely to be generally aware of the Guide, and women were also more specifically aware (p = .01). Physical activity levels were positively associated with the general (p < .001) and specific (p < .001) awareness of the Guide. Changes in general familiarity and specific recommendations over 1 year were observed. Conclusions. The majority of those surveyed were not familiar with the Guide. Men, individuals with a lower education, and older individuals may need to be specifically targeted. (Am J Health Promot 2011;25[5]:294-297.)
