Heart disease risk factors greater for women, blacks
A new study from the American Heart Association provides more evidence of who’s at greatest risk for developing cardiovascular disease. The results, published in Circulation, show women are at a higher risk for heart disease than men, and that blacks have an increased risk compared to white people.
Researchers from Brigham and Women’s Hospital examined population attributable risk (PAR) for five adjustable heart disease risk factors: high cholesterol, smoking, obesity, high blood pressure, and diabetes. PAR measures the commonality of a risk and how much it plays a role in increasing heart disease risk. The goal of the study was to see if education and health awareness about risk factors can have a positive effect.
Analyzing 13,541 people from Atherosclerosis Risk in Communities study, individuals ages 52 to 66 had four examinations during four time periods between 1987 and 1998. The researchers calculated the influence of each adaptable PAR risk factor over a 10-year period.
The PAR risk factors remained constant for African-Americans but decreased for white populations. Diabetes and high blood pressure were found to play a larger role in heart disease risk for women than men and in blacks compared to white people. Obesity remained a consistent risk factor. But the researchers did find that the number of smokers and people with high blood pressure has decreased in recent years.

Top of head concussions most severe
There’s more insight into the effect of concussions from contact sports. A study from the American Academy of Pediatrics has found that where a collision occurs on a person’s head can make a difference in its effects, with blows to the top of the head often resulting in the most severe injuries.
Researchers looked at data compiled from the National High School Sports-Related Injury Surveillance Study, which provides rates and circumstances of concussions suffered by high school football players during direct player contact.
The largest percentage of concussions–44.7 percent–caused by football collisions were to the front of the head. Collisions on the side of the head occurred 22.3 percent of the time. The reseachers said there wasn’t much of a difference between the effects of these two types of collisions.
However, collisions on the top of the head were more likely to cause a player to go unconscious (8 percent of the time) compared to those on other parts of the head (3.5 percent). These collisions usually occur when a player lowers his head before impact. These concussions, say experts, can be prevented by learning proper tackling techniques.
Concussions are classified as a traumatic brain injury and actually disrupt how the brain functions. Teens and children take longer to recover from concussions than adults and symptoms may not appear immediately after a collision.
The study was published in the journal Pediatrics.
