This trial has been completed.
|Conditions||overweight, obese, spinal cord injury|
|Treatments||lifestyle intervention, exercise control|
|Sponsor||University of Miami|
|Start date||September 2010|
|End date||September 2016|
|Trial size||29 participants|
|Trial identifier||NCT01467817, TMP-MN-009|
The purpose of this study is to determine how exercise and nutritional guidance and supplementation affects your physical fitness, risk for heart disease, your body's ability to burn fat, and your opinions about your health.
|Intervention model||single group assignment|
|Primary purpose||health services research|
time frame: 12 months
Male or female participants from 18 years up to 65 years old.
Inclusion Criteria: - participants will include 64 men and women aged 18-65 years with SCI (AIS A-C) at the C5-L1 levels for more than 1 year. - the International Standards for Neurological Classification of SCI (ASIA/ISCoS) will serve as benchmarks for subject classification. A physician-rater experienced in these procedures will classify subjects upon study entry. Exclusion Criteria: Study candidates will be excluded from study because of: - structured exercise conditioning for recreation or competition within 6 months of study entry; - defined diet involving caloric restriction or nutrient modification; - weight loss or gain of 5% within the preceding 6 months; - surgery within 6 months; - pressure ulcer within 3 months; - upper limb pain that limits exercise; - recurrent acute infection or illness requiring hospitalization or IV antibiotics; - pregnancy; - previous MI or cardiac surgery; - 6 month history of glucose-lowering and lipid-lowering drug therapy; - Type I or II diabetes (by WHO criteria); and - daily intake of vitamin supplements exceeding 100% RDA.
|Official title||Obesity/Overweight in Persons With Early and Chronic SCI: A Randomized Multi-Center Controlled Lifestyle Intervention|
|Principal investigator||Mark S Nash, PhD|
|Description||The study plan will enroll 80 persons with Spinal Cord Injury (SCI) who are overweight/obese and have fasting atherogenic dyslipidemia and dysglycemia. A Data Safety Management Board will oversee the trial. Interventions will include 6 months of structured lifestyle intervention incorporating education, exercise, diet, and behavioral support A second arm will test benefits of exercise alone while controlling for investigator contact. Multiple baselines tested before intervention will serve as a treatment control. Exercise will include a six-month circuit resistance training program already established as effective in fitness attainment for persons with paraplegia and tetraplegia. Dietary intervention over the same period will balance caloric expenditure measured by indirect calorimetry and food intake, the latter coming from a Mediterranean style diet having effectiveness established in the DPP for durable weight loss and diabetes prevention. The investigators and personal 'lifestyle coaches' will then shape and follow client-specific exercise and diet programs to be conducted for 12 months in the home or community-based centers. Behavioral approaches will include a 16-week training curriculum presented in both small groups and with the lifestyle coaches. Other behavioral approaches will include customized trial information booklets, performance incentives, outcome challenges between centers, and use of the VA Telehealth system for performance tracking, compliance assessment, and motivational support. Study specific aims and their accompanying hypotheses will test effects of intervention on: 1) reducing body weight and radiographically-derived body fat, 2) improving fitness as assessed by endurance, strength, and anaerobic power, 3) reducing risks of fasting dyslipidemia, post-prandial lipemia, and insulin resistance, and 4) enhancing perceived health-related quality of life. Data will be analyzed by Multivariate analysis with repeated measures. Ancillary testing will investigate effects of intervention on the whole body oxidation of fat at rest and following food intake, and examine the relationship between dietary intake and caloric expenditure at the beginning and the end of the 18 month study. The primary trial goal pays fidelity to the DPP by targeting sustained loss of 7% of body weight, a proven countermeasure for prevention of diabetes. Positive results of training will represent the first evidence-based randomized multi-center trial of sustained weight loss in persons with SCI - military or civilian. In the near term the data will provide evidence needed to initiate health reform of military and non-military constituencies with disability. The information will also underwrite changes in dietary support of newly injured persons. The information will further provide a roadmap for clinicians to institute client-centered programs of health planning and recovery. As the extension phase will test both home and community-based programs, deployment to wider military constituencies of persons with SCI can be achieved through VA Community Outpatient Clinics. The trial can also become a roadmap to weight and disease management experience by persons with physical impairments other than SCI.|
