Long-Term Follow-Up of the Telemonitoring Weight-Reduction Program "Active Body Control".

The Active Body Control (ABC) weight-reduction program is based on telemonitoring of physical activity and nutrition together with telecoaching by weekly counseling letters sent by post or by e-mail. The study presented here reports the results of a 1-year follow-up of 49 patients with the metabolic syndrome who had lost weight with the aid of the ABC program in the preceding year. The weight regain after the second year in patients not receiving any further care ("ABC discontinued" group; n = 24) and the potential benefit of continuing with the ABC program with monthly counseling letters ("ABC continued" group; n = 25) were investigated. The relative weight changes after the first year had been, respectively, -13.4% and -11.4% in the "ABC discontinued" and "ABC continued" groups, and after the second year they decreased by, respectively, 4.4 and 2.8%. However, this difference in weight regains between the two groups was not statistically significant. It is concluded that three-quarters of the weight loss after 1 year is maintained after the second year. The decision whether to continue with the ABC program after 1 year should be made individually.

Weight loss by telemonitoring of nutrition and physical activity in patients with metabolic syndrome for 1 year.

OBJECTIVE: Mobile technology can improve lifestyle programs, but the monitoring techniques and carer feedback need to be optimized. To this end, we investigated the efficacy of telemonitoring physical activity and nutrition over 12 months in patients with metabolic syndrome in a randomized, parallel-group, open trial. METHODS: Screening all over Germany yielded 184 patients with metabolic syndrome. All patients attended a single 2-hour instruction meeting in their region concerning a combination diet and the importance of physical activity. Thereafter they were randomized into a control group (controls, n = 62) or one of 2 different intervention groups. Both intervention groups were issued accelerometers, which measured physical activity, recorded daily weight and calorie intake, and transmitted these data to a central server for use by patient carers. In the Active Body Control Program of University of Magdeburg (ABC) intervention group (n = 60), information and motivation was ensured by weekly letters. In the 4sigma telephone coaching (4S) intervention group (n = 58), this was accomplished by monthly telephone calls from the carers. Clinical and biochemical data for all patients were collected at 0, 4, 8, and 12 months without any regular face-to-face meetings between patients and carers. The primary endpoint was weight loss and the secondary endpoint was the presence of metabolic syndrome. RESULTS: After 12 months the dropout rates in the control, 4S, and ABC groups were respectively 35%, 17%, and 18%. The adjusted relative weight losses after 12 months were respectively 3.7%, 8.6%, and 11.4% (all p < 0.000 versus baseline). ABC was more effective than 4S (p = 0.041); 43% of the patients completing the study in the ABC group lost more than 15% of their baseline weight. The diagnosis of metabolic syndrome was no longer applicable in 58% of the cases in the ABC group, in 41% of the 4S group, and in 33% of the controls. CONCLUSIONS: Telemonitoring of physical activity and nutrition markedly improves weight loss and markers of metabolic syndrome.

Weight loss in obese patients with type 2 diabetes: effects of telemonitoring plus a diet combination - the Active Body Control (ABC) Program.

AIMS: We evaluate the efficacy of the "Active Body Control (ABC) Program" for weight reduction in patients with type 2 diabetes. METHODS: The ABC program combines telemonitoring of the physical activity with a low-calorie diet also preferring carbohydrates with low glycemic indexes. In this 6-month, randomized, clinical trial 35 patients (aged 57 ± 9 years; BMI=35.3 ± 5.7 kg/m(2)) were treated according to the ABC program and 35 control patients (aged 58 ± 7 years; BMI=34.8 ± 5.9 kg/m(2)) received standard therapy. RESULTS: After 6 months the mean weight loss in the intervention group was 11.8 kg ± 8.0 kg. Glucose and HbA1c were lowered by respectively 1.0 mmol/l and 0.8 percentage points (p=0.000, respectively). The proportion of patients with HbA1c>7% fell from 57% to 26%. Antidiabetic drugs were discontinued in 13 patients (39%) and reduced in 14 (42%). The reduction of costs on medication per patient was € 83 in 6 months. In the control group, there were no relevant changes in body weight, laboratory values or drug treatment. CONCLUSIONS: The ABC program effectively lowers body weight, Hb1Ac and antidiabetic drug use in patients with type 2 diabetes.
