Heart healthy education. Effectiveness of teaching methods in the workplace.

One fourth to one third of employed workers in this country have at least one of three major risk factors for coronary heart disease. This pilot study examined differences between educational methods used in an occupational setting. The specific aims of the quasi-experimental study were: to determine differences between two groups of subjects who received either group support and instruction or only written instruction; and to determine the association between the practice of heart healthy behaviors and decreased blood cholesterol levels. No significant differences were found between the two groups in cholesterol and behavior changes. However, there was a significant difference between pre- and post-instruction for all subjects. The study documented significant changes in cholesterol levels, cholesterol and fat intake, and weight reduction.
