Lifestyle Interventions in Turkish-background Patients With Metabolic Syndrome and Diabetes in Germany

The investigators conducted a prospective, randomized, two-arm parallel study. In both arms, patients were instructed in a 12-week diet that was reduced by in caloric content by at least 30% based on calorimetric measurements of 24 h resting energy expenditure and estimated additional expenditures by diet- and activity-induced thermogenesis. Before and after the diet, anthropometric measures and various MetS-associated blood parameters were determined.

The subjects were not instructed in an exercise program. However, the subjects were advised on the value of increased physical activity. For additional motivation, effects were tested by an activity monitor. Therefore, in one of the arms, 24 hour locomotor activity and energy expenditure were determined by means of the SenseWear® MF armband (Body Media Inc., AliphCom dba Jawbone®, Pittsburgh, PA, U.S.A.). This device detects activity contest using accelerometers and assesses daily energy expenditure. For allocation of the subjects, a computer-generated list of random numbers was used. The randomization sequence was created using SPSS 18 (SPSS, Inc., Chicago, IL, USA) statistical software and subjects were assigned to be tested or not for locomotor activity with a 1:1 allocation using random block sizes of 2, 4, and 6.
