The purpose of this study was to examine changes in physical activity and healthy eating knowledge and behaviors associated with the level of exposure to POWERPLAY, a men-centered workplace health promotion program.


This study is based on a quasi-experimental prepost design. Using a computer assisted telephone interview survey, data regarding program exposure and physical activity and health eating knowledge and behaviors were collected from men (N = 103) in 4 workplaces.


Exposure scores were calculated and participants were categorized as having low (n = 54) or high exposure (n = 49) to POWERPLAY. Compared with the low exposure group, those reporting high exposure scored significantly higher on physical activity knowledge (F (1, 99) =14.17, P < .001, eta2 = .125) and health eating knowledge (F (1, 99) =14.37, P = .001, eta2 = .111). The high exposure group also reported significantly more minutes walked place to place (F (2, 206) = 3.91, P = .022, eta2 = .037) and on minutes walked for leisure (F (2, 230) = 3.08, P = .048, eta2 = .026).


POWERPLAY shows significant promise as a workplace health promotion approach and may have an even greater impact when program exposure is augmented with environmental and policy changes.
