Longevity News & Review

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 20,000 physician and scientist members from 90 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, A4M president, and Dr. Robert Goldman, A4M chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary

Abnormal Sleep Patterns in Women Linked to Stroke
In previous studies, the impact of the length of sleep per night has been linked to increased risk of death, but a new study by Jiu-Chiuan Chen, from the University of North Carolina School of Public Health, and colleagues establishes a direct relationship between sleep patterns and cardiovascular disease. In the team’s study of data from the Women’s Health Inititiative Study, involving 93,175 women participants (ages 50 to 79), the team found that those women who slept a duration of 6 hours or less, 8 hours, or 9 hours or more per-night had an increased risk of stroke of 14 percent, 24 percent and 70 percent, respectively (compared to those women who slept seven hours a night). In addition, the adverse effects of sleeping six hours or less was found to be more pronounced in those women with an existing cardiovascular issue; in this group, less sleep increased their risk of stroke by 22 percent.

Dr Klatz remarks: The restorative role of sleep is often underestimated. This study is important because it establishes clearly that abnormal sleep durations have a direct impact on the risk of stroke. Stroke is the No. 3 cause of death in the United States, and costs the nation $65.5 billion in 2008 in medical costs and disability. The suggestion that normalization of sleep patterns may reduce stroke risk is one that warrants further investigation.

US Adult Obesity Rates Continue to Expand
According to the United States Centers for Disease Control and Prevention, 25.6 percent of America’s adult population qualified as clinically obese in 2007, up from 24 percent in 2004. Twenty-seven of America’s states have a body mass index (BMI) of/greater than 30. In addition, the obesity prevalence stood at 31.7 and 30.2 percent, respectively, for men and women ages 50 to 59 years.

Dr. Goldman observes: Obesity is a significant public health problem, with serious implications for the health and wellbeing of the American public. Clearly it is incumbent upon physicians and health practitioners to encourage that patients participate in a regular program of aerobic exercise, supplemented by strength training, to help shed these dangerous excess pounds.

Heart Disease Linked to Worse Mental Function & Predicts Dementia
Archana Singh-Manoux, from the University College London, and colleagues completed a study of 5,837 middle-aged participants in the Whitehall study, which began in 1985 and consists of a group of civil servants working in the Whitehall region of the United Kingdom. The researchers found that coronary heart disease is associated with a worse performance in mental processes such sa reasoning, vocabulary and verbal fluency. The study also found that the longer ago the heart disease had been diagnosed, the worse was the person’s cognitive performance, an effect that was particularly marked in men.

Dr Klatz remarks: This large-scale study suggests the link between coronary heart disease and poor cognitive function. While future study is warranted to elucidate the exact causal mechanisms, this study is important in that it potentially identifies a major risk factor for dementia that may be effectively intervened, or modulated, at an early stage.
