Longevity News and Review provides readers with the latest information in breakthroughs pertaining to the extension of the healthy human lifespan. These news summaries are compiled by the American Academy of Anti-Aging Medicine (A4M; www.worldhealth.net), a non-profit medical society composed of 24,000 physician and scientist members from 110 nations, united in a mission to advance biomedical technologies to detect, prevent, and treat aging related disease and to promote research into methods to retard and optimize the human aging process. Dr. Ronald Klatz, M.D., D.O., A4M President, and Dr. Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their insightful commentary.
Better Diet Helps to Improve Quality of Life
Bamini Gopinath, from the University of Sydney (Australia), and colleagues studied data collected on 1,305 men and women, ages 55 years and older, who were enrolled in a large Australian study of common eye diseases and general health. Participants filled out questionnaires about what they ate and how often in 1992 to 1994. Researchers scored each person’s diet on a scale from 0 to 20 based the Australian Guide to Healthy Eating. Higher scores indicated better diets. The one-quarter of participants with the highest-quality diets had scores above 11.1. The one-quarter with the poorest diets scored 8.1 and below. Five and ten years after reporting on their diets, subjects completed surveys assessing their quality of life with regard to physical health, mental health, social functioning and vitality. Each area was measured on a scale of 0 to 100. On average, participants with the highest diet scores also reported a better quality of life. The team observed that physical function was almost six points higher among the healthiest eaters than the least healthy. As well, general health was four points higher among healthy eaters and vitality was five points higher. The study authors conclude that: “Higher diet quality was prospectively associated with better quality of life and functional ability.”
Dr. Klatz observes: “Issues with mobility are a major factor in reduced quality of life in aging. Australian researchers report that older men and women who follow healthy eating guidelines tend to maintain the capacity for independent living.”
Physical Activity Reduces Heart Injury
Moderate physical activity in sedentary older adults reduces the progression of injury to the heart, submits Christopher DeFilippi from the University of Maryland Medical Center (Maryland, USA), and colleagues. In a pilot study, 310 adults 70 years and older with a previously sedentary lifestyle, were randomly assigned to one-year supervised physical activity or to health education controls. The researchers measured troponin T, a blood-based injury marker which historically has been used for the diagnosis of heart attack was measured with a new high sensitive cardiac assay (hs cTnT). The team observed that troponin T levels, measured at baseline and at one year, had more than a three times increase in the control population than in the exercise group. The lead author posits that: “Our findings suggest biochemical evidence to support the old adage, ‘You’re never too old to start a physical activity program to improve cardiac health.’”
Remarks Dr. Goldman: “Further expanding the scientific data demonstrating the health benefits of physical activity, this team finds that older sedentary adults can reduce potential injury to the heart via regular moderate-intensity exercise.”
Long Walks Lower Stroke Risk
Barbara J. Jefferis, from the University College London (United Kingdom), and colleagues studied 3,435 healthy men, ages 60 to 80 years, who were enrolled in the British Regional Heart Study. Following the subjects for an average of 10.9 years, the investigators tracked cardiovascular blood markers including C-reactive protein (CRP), D-dimer, and N-terminal pro-brain natriuretic peptide (NT-proBNP). The team observed that men who walked 8 to 14 hours per week were at one-third lower risk of stroke, compared to men who walked no more than three hours a week or did not walk at all. The stroke risk was about two-thirds lower for men who walked more than 22 hours per week. The association was found to be independent of walking pace and activity level. Reporting that: “Time spent walking was associated with reduced risk of onset of stroke in dose-response fashion,” the study authors submit that: “Walking could form an important part of stroke-prevention strategies in older people.”
Comments Dr. Klatz: “Walking is a popular form of physical activity, one that can be conducted by older adults who live independently. UK researchers report that walks of an extended duration may help to reduce the odds of stroke, among older men.”
Anti-aging medicine is the fastest-growing medical specialty throughout the world and is founded on the application of advanced scientific and medical technologies for the early detection, prevention, treatment, and reversal of age-related dysfunction, disorders, and diseases. It is a healthcare model promoting innovative science and research to prolong the healthy lifespan in humans. As such, anti-aging medicine is based on solid scientific principles of responsible medical care that are consistent with those applied in other preventive health specialties. The goal of anti-aging medicine is not to merely prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.
