Take Heart II: Replication of a worksite health promotion trial

The purpose of this study was to evaluate the effects of a revised worksite health promotion program that featured an employee steering committee/menu approach to intervention. The ''Take Heart II'' program was evaluated using a quasi-experimental matched-pair design with worksite as the unit of analysis. Experimental and control worksites did not differ on baseline organizational or employee demographic variables or on baseline levels of dependent variables. Outcome and process results revealed consistent, but modest effects favoring intervention worksites on most measures. Cross-sectional analyses generally failed to produce statistically significant intervention effects, but cohort analyses revealed significant beneficial effects of the Take Heart II intervention on eating patterns, behavior change attempts, and perceived social support. Neither analysis detected a beneficial effect of intervention on cholesterol levels.
