We hypothesized that a 12-month health-counselling intervention will lead to changes in a) health behaviour (increased physical activity and consumption of fruit and vegetables, and improved fat quality), b) a moderate reduction in excessive weight (10%) (main outcome), c) improved alertness at work and less day-time fatigue, improved duration and quality of sleep, and d) improved health-related fitness and decreased proportion of men with MeS.
Volunteer participants (N=140) are obese male commercial truck drivers. They are randomised into two groups, intervention (INT) and control (CON), for a period of 12 months. The INT group is followed for another 12 months. After the 12 months, the CON group receives a shorter intervention (3 months), after which they are followed for 9 months. Assessments for both groups occur at 0, 12 and 24 months from the start.
The intervention consists of individual monthly counselling (6 times face-to-face, 7 times by telephone) throughout the first study year.
