Introduction: Physical inactivity is a major contributor to the development of lifestyle diseases such as type 2 diabetes mellitus (DM2) (Werle u. a. 2006) and incurs significant costs (Ding u. a. 2016). Patient education is well established, but does not always lead to sustainable lifestyle changes (Wood & Neal 2016). In DM2 patients, activities of 3 000 steps per day already have a positive effect on health (Tudor-Locke u. a. 2004a). Methods: In the partially randomized, controlled, open-labeled intervention study, individuals with non-primary insulin-dependent DM2 were consecutively trained and followed for 1 year in 11 diabetes primary care practices (DSPs). The 90-minute DiSkoPlus (DP) training module integrates a pedometer (PM) for exercise control and subsequent diabetes self-management. Exercise experience and exercise management occur in the intervention group (IG) with and in the control group (KG) without the PM. The PM records total steps/day (TS) and contiguous (aerobic) steps/day (AS) in total and minutes (AWT). Results: 63 patients aged 60±10 years, 37 were women (59 %), were followed for 12 months: IG, N = 35 (56 %); KG, N = 28 (44 %). At the end of the study, there was a clinically relevant HbA1c reduction of ≥ 0.4 %, in 23.3 % of cases in IG versus 18.5% in KG. 53.4 % of IG patients (KG: 57.1%) had a HbA1c -value < 6.5 % and a proportion of 6.7 % of IG patients (KG: 7.1 %) had a value < 5.7 %. Patients in the IG had a higher skeletal muscle percentage after one year and they covered a longer distance in the 6-minute walk test (499±94.3 to 534±103 m, p = 0.024 1 ). Blood pressure decreased to 76.8±10.5 mmHg (systolic) and 125±10.5mmHg (diastolic) in IG and to 76.2±9.47 mmHg (systolic) and 126±10.6 mmHg (diastolic) in the KG, respectively. Body weight decreased from 90.1±19.6 kg to 87.2±17.6 kg in the IG and from 85.8±18.9 kg to 83.6±18.8 kg in the KG. By BMI, normal-weight and overweight subjects increased by 2 % in IG and 7 % in KG. PM-data showed a decreasing trend. In males, there was a decrease in AWT from 28.77±46.46 to 20.81±37.82 minutes (p = 0.00326), whereas the decrease was not significant in females (from 20.55±28.46 to 18±29.36 minutes; p = 0.0949). The percentage of subjects receiving medication (diabetic metabolic condition, hypertension) decreased from 88.6 % to 71.4 % in the IG and increased from 75 % to 78.6 % in the KG. Conclusion: Overall, in the relatively small study described here, no significant differences were demonstrated between the DiSko and DiskoPlus training module over the one-year period. However, more positive trends emerged in the IG (18/27 risk factors) than in the KG (15/27 risk factors), which speaks for the use of PM.
