Engaging high-risk populations in community-level fitness promotion: ROCK! Richmond.

The purpose of this study was to determine whether ROCK! Richmond, a healthy nutrition and physical activity promotion initiative of the Richmond (Virginia) City Department of Public Health was effectively recruiting the high-risk individuals for whom this lifestyle change intervention was intended. The effectiveness of recruitment, participant demographic and health status characteristics were compared with those of respondents to a random sample survey conducted 18 months earlier. Relatively high-risk residents were recruited.
