Lifestyle and cancer: the relative effects of a workplace health promotion program across gender and social class.

A self-administered cross-sectional survey was used to assess the relative impact of a health promotion program on blue- and white-collar workers of both sexes. The program operated in five different types of organizations and consisted of exercise, nutrition, smoking, stress, breast and testicular self-examination. Significant positive improvements occurred on at least five health behaviors for female workers reporting and four behaviors for male workers, with the greatest gains among blue-collar women. Several study limitations are noted suggesting a cautious interpretation of the results.
