Blood type tied to heart disease risk
A new study published in the journal BMC Medicine suggests that people whose blood type is A, B or AB have a higher risk of heart disease and shorter life spans compared to people who have type O blood.
For the study, researchers from the U.S. National Institutes of Health followed about 50,000 middle-age and elderly people in northeastern Iran for an average of seven years. They found that people with non-O blood types were 9 percent more likely to die during the study for any health-related reason, and 15 percent more likely to die from cardiovascular disease, compared with people with blood type O. The researchers also found that people with non-O blood types had a 55 percent increased risk of gastric cancer – a disease common in northeastern Iran – compared to people with type O blood.
While researchers don’t have a conclusive reason for these results, several factors may put non-O blood types at greater risk for certain diseases. For instance, people with non-O blood types have an increased tendency to form blood clots, and this higher coagulation might lead to more heart problems.
Researchers emphasize that people should not be overly concerned by the study’s results, noting that blood type is just one factor among many that contributes to a person’s overall health and emphasizing that a healthy lifestyle remains the key factor in how long you live.

People who work long hours at higher risk for alcohol excess
People who work more than 49 hours a week are more likely to engage in “risky alcohol consumption,” according to analysis by Finnish researchers of studies done in 14 countries.
Scientists at the Finnish Institute of Occupational Health in Helsinki conducted a cross-sectional analysis of studies involving 333,693 adults, and a prospective analysis of studies involving 100,602 adults from nine countries. Researchers analyzed the number of hours people worked each week and correlated it to alcohol use. Risky alcohol use was defined as more than 21 drinks each week for men, and more than 14 drinks each week for women.
The cross-sectional analysis found that working long hours increased the likelihood of risky alcohol consumption by 11 percent and the prospective analysis found the likelihood to be 12 percent. Analysis of individual participant information from 18 prospective studies found that people who worked 49 to 54 hours a week were 13 percent more likely to engage in risky alcohol consumption, compared to those who worked 35 to 40 hours a week.
The results held even after accounting for the participants’ sex, age, region and socioeconomic status, according to the study, which was published in _BMJ (British Medical Journal). _
Researchers acknowledged that alcohol consumption can be a stress reliever for people working long hours and facing deadline demands. They said their research supports the recommendations of the European Union Working Time Directive that people not work more than 48 hours a week.
