Process evaluation of an occupational health guideline aimed at preventing weight gain among employees.

Abstract

To evuate the process of an occupational health guideline aimed at preventing weight gain. Quantitative data on seven process items were assessed and linked to effects on employees' waist circumference and body weight at 6 months. Occupational physicians (n = 7) implemented the guideline partly with respect to the environmental level, but performed well at the individual level. Behavioral change counseling was performed "to some extent." Employees (n = 274) showed high reach (86%), satisfaction (7.1), and attendance rates (4.4 of 5 sessions). Significant effects were found on waist circumference (-1.5 cm to -2.1 cm) and body weight (-0.9 kg to -1.4 kg) among employees with higher attendance and satisfaction rates. Workplace health promotion via an occupational health guideline is feasible, but the environmental component and behavioral change counseling need revisions before practical application.
