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;, 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.

Happiness Rises with Age
Angelina R. Sutin of Florida State University College of Medicine (Florida, USA), and colleagues used two large-scale longitudinal studies, NIH’s Baltimore Longitudinal Study of Aging (BLSA) and the CDC’s National Health and Nutrition Examination Survey (NHANES), involving  more than 10,000 repeated assessments across 30 years that surveyed well-being, health, and other factors. When the researchers analyzed the data across the whole pool of participants, older adults had lower levels of well-being than younger and middle-aged adults. Factoring in the effects of “birth cohort” – people born around the same time who may have had unique experiences that shape the way they evaluate happiness and optimism, the team analyzed the same data and found that life satisfaction increased over the participants’ lifetimes. In short, self-reported feelings of well-being tend to increase with age, but a person’s overall level of well-being depends on when he or she was born.

Dr. Klatz observes: “Psychological well-being has been linked to many important life outcomes, including career success, relationship satisfaction, and even health. While unique experiences shape the way that people evaluate happiness and optimism, this large-scale study reveals that life satisfaction increases over subjects’ lifetimes.”

Beef Up to Maintain Muscle
Stuart M. Phillips, from McMaster University (Canada), and colleagues enrolled 45 men, average age 59 years, in a study that found that eating a six-ounce (170 g) serving of 85% lean ground beef resulted in significant treatment the rate of muscle protein synthesis following exercise. This determination is double the current recommended serving sizes of meat in Canada.   Study authors propose that: “Ingestion of 170 g of beef protein is required to stimulate a rise in myofibrillar [muscle protein synthesis] over and above that seen with lower doses.”

Remarks Dr. Goldman: “Sarcopenia, or the gradual loss of muscle mass, is a common consequence of aging, and poses a significant risk factor for disability in older adults.  Six-ounces of beef helps to renew new muscle protein, among middle-aged men.”

Stress May Prompt Diabetes
Masuma Novak and colleagues utilized this data to observe that of the total sample, 6,828 men without any previous history of diabetes, coronary artery disease or stroke were analysed. A total of 899 of these men developed diabetes during the follow up.  The team found that those men who reported permanent stress had a 45% higher risk of developing diabetes, compared with men who reported to have no or periodic stress. The study authors conclude that: “Self-perceived permanent stress is an important long-term predictor of diagnosed diabetes, independently of socio-economic status, BMI and other conventional Type 2 diabetes risk factors.”

Comments Dr. Klatz: “Since the 1970s, a large population based cohort study has been undertaken at the Sahlgrenska Academy, University of Gothenburg (Sweden) to monitor the health of men born in Gothenburg between 1915 and 1925.  In an intriguing finding, thus Swedish team proposes link between permanent stress and the risk of developing type-2 diabetes, among 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.
