Alcohol consumption – a method to prolong life in old age?

Some studies have suggested that moderate alcohol consumption extends life and protects the heart, while others have negated these benefits, arguing that the former studies are flawed and that there is no such thing as safe alcohol consumption. Moderate drinking — sometimes defined as 2–7 glasses of wine per week — may also keep depression at bay, according to some research, although the same study showed that heavy drinking increased depression risk. When it comes to the cardiovascular benefits of alcohol, the results are mixed. Some suggest that moderate consumption of wine and beer, but not spirits, protects against cardiovascular disease, while other results point to protective benefits of drinking vodka as well as wine. now, the results of a new, large-scale study are in. The Health and Retirement Study (HRS) is "one of the largest and most rigorous" studies on alcohol consumption and death risk in the United States, and a new report has presented the findings of a 16-year follow-up period. The analysis revealed that moderate and occasional drinkers had lower death rates than abstainers. Current abstainers had the highest mortality rates. However, the researchers explain, this could result from reverse causation — that is, people may have stopped drinking when their health became poor. Also, importantly, moderate and occasional female drinkers were less likely to die prematurely than lifetime abstainers.

What do you know about erectile dysfunction?

Erectile dysfunction refers to an inability to either produce or maintain an erection that is firm enough to have sexual intercourse. Although erectile dysfunction is thought to be relatively common, its exact prevalence has been difficult to ascertain; studies have produced a wide range of results. A group of researchers recently set out to examine the prevalence of erectile dysfunction. They also assessed the evidence of its association with cardiovascular disease and mortality. Understanding the size and scope of erectile dysfunction is more important than ever. To investigate, the scientists took data from earlier studies. In total, they identified 41 relevant studies that examined the prevalence of erectile dysfunction or its role in other conditions. The researchers found an incredible variety; prevalence rates ranged from just 3% to 76.5%. When the scientists looked for links between erectile dysfunction and cardiovascular disease, they found a "wealth of evidence." They observed increased prevalence and incidence in a number of conditions, including myocardial infarction, ischemic heart disease, hypertension, stroke, angina, arteriosclerosis, and peripheral vascular disease. The authors conclude that "The global prevalence of [erectile dysfunction] is high and represents a significant burden on the [quality of life] of men and their partners." They also believe that "Physicians should consider screening for [erectile dysfunction] in at-risk patients, as information may not be volunteered."
