Effect of an IT-supported home-based exercise programme on metabolic syndrome in India

Summary We studied the effectiveness of a home-based exercise programme with information technology (IT) support in people with metabolic syndrome in India. Ninety-four participants with metabolic syndrome (mean age 50 years) were randomized into two groups. Both groups received a 12-week home exercise programme and Group 2 received additional IT support for health education. Before and after the exercise programme, participants were measured for arterial stiffness using applanation tonometry, exercise capacity using an incremental shuttle walk test and quality of life (QoL) using the SF-36 questionnaire. Sixty-one participants completed the post intervention tests. There was a significant reduction in systolic blood pressure, mean pressure and aortic systolic pressure in both groups. Pulse wave velocity, aortic pulse pressure and aortic diastolic pressure showed significant reductions only in Group 2. There were no significant changes in QoL measures, except vitality in Group 2. There was significant improvement in fasting blood glucose in Group 2, cholesterol in Group 1 and triglycerides in both groups. The participants' exercise capacity did not change significantly, although the mean duration of regular exercise was 7.2 weeks for Group 1 and 10.0 weeks for Group 2 (P = 0.019). Metabolic syndrome was reversed in 16% of the participants in both groups. IT support, through mobile text messages and phone calls, may be helpful in metabolic syndrome. Longer-term studies are now required.
