Brief Summary

Over 30% of American adults have hypertension (HTN) (high blood pressure), and the rate increases considerably with age; 64% of men and 78% of women over 65 have HTN. High blood pressure associated with HTN can force of the blood against artery walls with enough pressure that it can eventually cause health problems, such as heart disease and stroke. HTN is one of the most significant causes of early death worldwide and one of the most preventable causes of death. Many studies reveal that lowering blood pressure (BP) reduces the incidence of diseases of the heart and blood vessels. Non-drug related treatments are known to reduce BP which can have a great effect on public health. Research suggests that Tai Chi (TC) is effective in lowering BP in patients with HTN, but because of the low quality of existing studies there is no definite proof. Also, it is not known how TC reduces BP. One possibility is that TC practice, which is shown to reduce psychological distress such as anxiety and depression and reduce the body's responses to stress, can improve the balance of the autonomic nervous system (the part of your nervous system that controls beating of the heart and the widening or narrowing of blood vessels). This may lead to lower BP. The investigators plan to investigate the pathways among autonomic, blood vessel, immune and psychological factors in relation to BP changes in response to 12-weeks of TC compared with Healthy Aging Practice-centered Education (HAP-E). 250 older adults (60+ years old) with mild HTN will be enrolled, and the investigators will take several measurements of heart and nervous system functioning. The investigators hypothesize that performing TC for 12 weeks will result in autonomic "re-regulation" which will improve BP and blood vessel health (Aim 1) and sympathetic nervous system (part of the nervous system that serves to speed up heart rate, contract blood vessels, and raise blood pressure) regulation of the immune system (Aim 2). Lastly, the investigators hypothesize that psychological factors will be related to TC effects on autonomic regulation (Aim 3). Findings from the investigators study will hopefully shed light on the pathways by which TC reduces BP. Also, the particular effects of TC ("meditative movement") in an older, "hard-to-treat" hypertensive population will be better understood.

Study Arms (2)

Healthy Aging Practice-centered Instruction (HAPI)

ACTIVE COMPARATOR

24 hours of group instruction in which experts present on a variety of health-related topics followed by class discussion, goal-setting, and goal review. Themes will include: sleep, nutrition, mental health, social support, bone-health, diabetes prevention, cognitive wellness, and resilience.

Behavioral: Healthy Aging Practice-centered Instruction (HAPI)

Tai Chi (CHI)

EXPERIMENTAL

24 hours of group instruction in 8 meditative Tai Chi movements.

Behavioral: Tai Chi (CHI)

Interventions

Sessions will include interactive activities derived from the CDC's "Program to Encourage Active and Rewarding LiveS (PEARLS)" and will include lectures based on health-related topics from presentations given by experts as part of the UC San Diego Stein Institute of Aging's Successful Aging project. The PEARLS Problem Solving Treatment (PST) group discussions will be facilitated by a trained instructor in order for participants to identify problems or barriers they have in engaging in healthy behaviors relevant to each of 12 topic areas (e.g. sleep, nutrition, mental health, social support, bone health, diabetes prevention, cognitive wellness, and resilience). Each session will be composed of: Successful Aging video (45 min), discussion (40 min), and identifying problem solving strategies (25 min) with a homework assignment each week, for a total of 24 hours of in-class instruction and discussion.

Healthy Aging Practice-centered Instruction (HAPI)
Tai Chi (CHI)BEHAVIORAL

Sessions will include expert instruction in the brief Yang-style 8-form Tai Chi meditative movements. Each class will include a 10-minute warm-up and cool-down plus 40 minutes of Tai Chi instruction and or practice, for a total of 24 hours of in-class instruction
