An Exploration of Effective Communication Channels for Improving Physical Activity and Diet Messages

Abstract

Background: While much research attention has been given to the impact of health behavior interventions, relatively little is known about the efficacy of communication channels for health messages. The purpose of this study was to evaluate the efficacy of various communication channels for behavior change messages that focus on promoting physical activity and healthy diet in Japanese suburban populations. Methods: A health communication campaign was created collaboratively in 2011–2013 with researcher-designed materials derived from enhanced community health resources presented in a variety of communication channels. Participants (n = 1,500) were recruited from the community. Findings: Public relations magazines, leaflets and newsletters were found to be effective channels for communicating health messages than other resources (Chi-square = 328.25, df = 7, p < .01, Cohen’s w = .74). This finding remained constant across gender and age differences. Discussion: These findings suggest that using a combination of public relations magazines, leaflets, and newsletters based on community health resources is effective way to disseminate health information in suburban populations.
