Overweight and obesity and reduced perceived general health were also more prevalent among employees with a low education. Employees with a low educational level more often had physically demanding jobs and jobs with low job control than better educated participants.

Twenty-nine percent of the baseline participants were lost to follow-up. Individuals with insufficient fruit and vegetable intake (OR = 0.65, 95 % CI 0.49–0.88) and smokers (OR = 0.53, 95 % CI 0.37–0.75) were less likely to fill out the follow-up questionnaire than workers with a healthy lifestyle. Older employees (OR = 3.01, 95 % CI 1.86–4.86) were more likely to repeat participation at 1-year follow-up.
