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 optimise the human aging process. Dr Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, and Dr Ronald Klatz, M.D., D.O., A4M President, physician co-founders of the anti-aging medical movement, distil these headlines and provide their commentary.
Screenings to Reduce Cardiovascular Disease
An estimated 900 million people in developing countries have high blood pressure, but a mere one-third are aware of their disease. Further, only 100 million of these people receive treatment, while only 5% of the total cases are controlled. Thomas Gaziano, from Harvard University, and colleagues report that a 25% increase in high blood pressure screening in 19 developing countries would reduce the number of cardiovascular disease events and deaths that occur each year by up to 3% in these countries. Furthermore, the incremental cost-effectiveness ratios of these screening programs were found to be well below one times GDP per capita in the 19 developing countries assessed.
Dr Klatz observes: Reporting that a 25% increase in blood pressure screening in 19 developing countries would reduce the number of cardiovascular disease events by up to 3% annually, these researchers reveal a simple – yet effective – approach for the effective management of premature cardiovascular-related deaths.
Score More with Exercise on the Shore
Exercise in the open air is good for you, but researchers from the Peninsula College of Medicine and Dentistry (United Kingdom) suggest that to reap the full benefits you should head for the coast or the countryside, rather than an urban park. Katherine Ashbullby and colleagues studied data from 2750 English respondents drawn from Natural England’s two-year study of people’s engagement with the natural environment. Assessing people who had visited urban parks, the countryside and the coast, the team found that all outdoor locations were associated with positive feelings (enjoyment, calmness, refreshment), but visits to the coast were most beneficial – and visits to urban parks least beneficial. This finding remained when the researchers took account of factors like people’s age, how far they had travelled, the presence of others and the activity they undertook. The study authors observe that: Our findings suggest it is time to move beyond a simple urban vs rural debate and start looking at the effect that different natural environments have on people’s health and well-being.”
Remarks Dr Goldman: Finding that exercising on a coastal shoreline delivers the greatest positive feelings of enjoyment, calmness, and refreshment, this team reaffirms the mind-body connection for health, wellness, and longevity.
Vitamin D Levels Linked to Alzheimer’s
A deficiency of Vitamin D has been shown by a number of studies contribute to cognitive decline. Cedric Annweiler, from the University of Angers (France), and colleagues analyzed data collected on 498 women, average age 79.8 years, who did not take Vitamin D supplements. Dietary intake of the vitamin was assessed using food surveys, and the women were followed for seven years. The team found that those women with lower vitamin D dietary intake (50 micrograms per week) at the studies start were at a greater risk of developing Alzheimer’s Disease, as compared to women with higher vitamin D dietary intake (59 micrograms per week). Additionally, the highest average intakes of vitamin D were associated with a lower risk of Alzheimer’s, as compared to lower intakes. Suggesting that vitamin D has been linked to protection of the hippocampal region of the brain, or that the vitamin influences clearance of beta-amyloid proteins, the study authors conclude that: “Higher vitamin D dietary intake was associated with a lower risk of developing [Alzheimer’s Disease] among older women.”
Comments Dr Klatz: People with higher intakes of Vitamin D may be at a lower risk of developing Alzheimer’s Disease. This data may suggest a future role for Vitamin D in preventing this devastating disease.
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.
