Objective: To evuate the process of an occupational health guideline aimed at preventing weight gain.
Methods: Quantitative data on seven process items were assessed and linked to effects on employees' waist circumference and body weight at 6 months.
Results: 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.
Conclusions: Workplace health promotion via an occupational health guideline is feasible, but the environmental component and behavioral change counseling need revisions before practical application.
