In-patient and Out-patient GCRC subsets Of the 40 enrolled subjects, 24 will be randomly assigned to a subset of patients who will be admitted for overnight stays in order to test insulin resistance parameters and to monitor nocturnal blood pressure. The remaining 16 subjects will have GCRC outpatient visits only. The rationale for an in-patient subset is logistical. Our protocol calls for patients to be admitted for baseline evaluation at a uniform time preceding the mindfulness intervention, and then at three later time points. All patients need to be evaluated as close to the same time as possible, as they are going through the intervention according to the same schedule. It is not logistically possible to admit 40 patients for overnight stays within a 10-14 day interval at four different time periods. Admitting a subset of 24 patients for overnight stay allows an adequate sample size to measure insulin resistance. The biological markers being measured require a larger sample size to show statistical significance, and this larger sample size can be achieved without inpatient stays.
