The purpose of this study is to examine if an individually tailored Internet intervention is more efficacious than an individually tailored print-based intervention and standard Internet intervention for physical activity adoption and maintenance among sedentary adults.
The objective of this study is to determine the differential effect of intervention delivery channel (phone versus print versus wait list control) on physical activity adoption and maintenance in previously sedentary adults. Both delivery channels have been found to be effective, but telephone-based interventions require more commitment on the part of the subjects and are more labor intensive than print-based interventions. Thus, we will conduct a randomized controlled clinical trial comparing three groups: 1) telephone-based motivationally-tailored individualized feedback; 2) print-based, motivationally-tailored individualized feedback; 3) minimal contact waiting list control condition (receive intervention after 12 months as controls). Two hundred and twenty-eight healthy, sedentary women and men ages 18-65 will be randomly assigned to one of the two interventions or the waiting-list control condition. Our primary hypothesis is that individuals randomized to either phone or print conditions will exhibit significantly higher levels of physical activity participation at 6 and 12 months than individuals in the waiting list control condition. And, in addition, that subjects randomized to the telephone condition will exhibit significantly higher levels of physical activity participation at 6 and 12 months than those in the print condition.
This is a prospective, non-randomised, 48 week study of the effect of protease inhibitor (PI) containing and non-PI containing antiretroviral regimens on the expression of adipocyte specific genes, protein levels and cellular structure in HIV-infected individuals, naive to therapy, who are starting therapy for the first time.
This is a randomised study of the effect of treatment with Combivir (zidovudine [AZT] and lamivudine [3TC]) and Kaletra (lopinavir [LPVr]), alone and in combination, on the development of abnormalities in lipid and glucose metabolism in HIV negative healthy subjects.
Cardiovascular disease is the main cause of death in patients on dialysis for end stage renal disease. Omega-3 fatty acids and antioxidants have been shown to be protective in the general population. A diet of fish and fruit, which will provide the fatty acids and the antioxidants is being tried in dialysis patients to assess the effect on cardiovascular disease in this high risk group.
The purpose of this study is to determine whether raloxifene compared with placebo lowers the risk of coronary events and reduces the risk of invasive breast cancer in postmenopausal women at risk for major coronary events.
The purpose of this study is to prove the hypothesis that the progression of renal and cardiovascular disease is more efficiently prevented when the angiotensin II receptor blocker valsartan is added to conventional antihypertensive therapy.
The purpose of this study is to determine whether N-acetylcysteine is effective in the prophylaxis of post-cardiopulmonary bypass acute renal impairment.
Does an oral selenium supplement increase blood levels of antioxidants in patients with established, smoking-related lung disease? Members of our study group recently discovered that elevated levels of the anti-oxidant GPx-1 may be protective against heart disease. We are studying whether selenium supplementation will improve GPx-1 levels.
