Worksite cholesterol and nutrition: an intervention project in Colorado.

The study purpose was to determine whether group intervention or an individual self help program proved to be more effective at lowering heart disease risk factors among employees in different worksites. Eight worksites and 502 employees in the Denver metropolitan area were selected for the project, with four randomized to Usual Care and four to the Special Intervention. Most worksites had < 200 employees. Employees were randomly assigned to either a control group receiving usual nutrition education or one of two special intervention groups in which employees selected to attend group nutrition education classes or complete an individual self paced nutrition education program. Results indicated that offering a choice of methods for the special nutrition education intervention was valuable, and both approaches modified behavior and certain physiological outcomes. Results suggested that enhanced nutrition education efforts in worksites may be effective and will realize greater benefits than a pamphlet or brief discussion following a worksite screening.
