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.
Two Personality Traits Help to Extend Longevity
Margie Lachman, from Brandeis University (Massachusetts, USA), and colleagues explored whether personality traits may exert a role. In this study, less educated people with higher perceived control in their life had a mortality rate three times lower than those with a lower sense of control. In fact, a high sense of control seemed to negate the mortality risks of lower education. This effect remained after adjusting for potential confounding variables, including health behaviors, depressed affect, and general health (chronic illnesses, functional limitations, and self-rated health). The study authors submit that: “These findings demonstrate the importance of individual perceptions of control in buffering the mortality risk associated with educational disadvantage.”
Dr. Klatz observes: “Previous studies have shown that people with a high school diploma or less education tend to die younger than those with a college degree or graduate training – but the association is not always true. These findings suggest that people who feel in control, and have a high sense of self-determination, are more likely to live longer and healthier lives.”
Manage Your Week to Manage Your Weight
Brian Wansink, from Cornell University (New York, USA), and colleagues explored the role of the seven-days-a-week human cycle on weight. The researchers enrolled 80 adults, ages 25 to 62 years, who were categorized according to relative weight changes: weight losers (-3% weight loss), weight gainers (+1% weight gain), and weight maintainers (-3% to 1% weight change). The study participants were asked to weigh themselves after waking up before breakfast. The minimum follow-up time was 15 days and maximum 330 days. Weekly weight patterns were analyzed across the three groups: weight losers, weight gainers and weight maintainers. The results revealed a clear pattern in weekly weight fluctuation with higher weight after weekends (Sunday and Monday) and decreasing weight during the weekdays reaching the lowest point on Friday. Unexpectedly the researchers found a difference between weight losers and weight gainers in these fluctuation patterns. Weight losers had stronger compensation pattern (i.e. after weekend the decrease started immediately and continued downward until Friday) whereas weight gainers had more variability between days and no clear decrease during weekdays. Weight losers reached week’s maximum weight in 59% of cases on Sunday and Monday and week’s minimum weight in 60% of cases on Friday or Saturday. Among weight gainers no such a pattern was seen. Minimum and maximum weights did not systematically appear on certain days but they were evenly distributed all over the week. Observing that: “Weight variations between weekends and weekdays should be considered as normal instead of signs of weight gain,” the study authors suggest that: “Those who compensate the most are most likely to either lose or maintain weight over time. Long-term habits may make more of a difference than short-term splurges.”
Remarks Dr. Goldman: “It is common for many people to lose a bit of weight on weekdays and gain a little weight on weekends. These US researchers enlighten on how and why the seven-days-a-week human cycle affects weight.”
Blueberry-Based Formula Boosts Brain Skills
Paula C Bickford, from the University of South Florida (Florida, USA), and colleagues have developed a formulation containing extracts from blueberries and green tea combined with vitamin D3 and amino acids – notably carnosine. The researchers enrolled 105 healthy men and women, ages 65 to 85 years, for a two-month study, during which half of the subjects received the formulation as a dietary supplement, and the other half served as controls. Those subjects who received the formulation demonstrated improvements in cognitive processing speeds, whereas those who did not receive the supplement showed no changes. Well tolerated without adverse symptoms, the study authors submit that: “Overall, the results of the current study were promising and suggest the potential for interventions like these to improve the cognitive health of older adults.”
Comments Dr. Klatz: “A persistent and common fear among aging adults is the decline and/or loss of the abilities to think, remember, and learn. This US team has devised a formulation composed of extracts from blueberries and green tea, plus vitamins and amino acids, that may help to improve cognitive processing speed in healthy older adults.”
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.
