Healthy Aging Resources to Thrive (HART)

2018-11-18 20:06:25 | BioPortfolio


Healthy Aging Resources to Thrive (HART) uses a rigorous two-stage randomized control design, adapted and refined based on pilot studies, to test a novel intervention to reduce sitting time in older adults. Half the participants will be randomized to the intervention aimed at decreasing sitting time, and the other half will be randomized to a healthy living control that does not focus on reduced sitting time. After 6 months, the intervention group will be further randomized so that half continue with the intervention and the other half receive no further intervention. All participants will be followed for 12 months.


Healthy Aging Resources to Thrive (HART) is a two-stage randomized controlled trial (RCT) of adults over age 60 with obesity to determine the efficacy of a novel sitting-reduction intervention and its impact on cardiometabolic risk markers. Participants will be randomized to a 6-month sitting reduction intervention (termed I-STAND) or healthy-living attention control (Stage 1).

After 6 months, I-STAND participants will be re-randomized to receive either booster sessions or no further intervention (Stage 2). Attention control participants will receive no further intervention. All participants will be followed for 12 months total with in person assessments at baseline 6, and 12 months. Primary outcomes are reduction in sitting time at 6 months, objectively measured using the activPAL device, and blood pressure. The design will answer novel questions about the impact of sitting reduction on cardiometabolic risk markers as well as maintenance of sitting reduction.

The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents.

Individual's ability to manage the symptoms, treatment, physical and psychosocial consequences and lifestyle changes inherent in living with a chronic condition.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
