Interventions
Two intervention conditions (phone-based [N=462] or Internet-based intervention[N=464]) or a reference group (N=460)
In addition, employees were randomized to either a group of employees having basic measures only (80% out of each group) or to a group of employees having additional measures (i.e. waist circumference
20% subjects of each group). The two-step randomization means there are six groups an employee could be assigned to.
