The survey reported in this document examined worksite health promotion and disease prevention activities in 1,507 private worksites in the United States. Specificlly, the survey assessed policies, practices, services, facilities, information, and activities sponsored by employers to improve the health of their employees, and assessed health promotion activities sponsored by a random sample of worksites with 50 or more employees. The survey was designed to describe characteristics of worksite health promotion activities in the private sector, to measure the level of change in worksite health promotion activity since baseline data was obtained from a 1985 survey, and to track worksite-related activities within the context of "Healthy People 2000: National Health Promotion and Disease Prevention Objectives." The main body of the report presents highlights of the survey by subject areas such as: high blood pressure, cholesterol, cancer, sexually transmitted diseases, smoking control, physical fitness, nutrition, weight control, prenatal education, mental health and stress management, alcohol and other drugs, program administration and support, incentives, and benefits and evaluation.
