Narrowed Leg Arteries Disable Women Faster Than Men: Study

Women coping with peripheral arterial disease (PAD) in the legs appear to lose mobility faster than men, new research reveals. PAD is marked by narrowing and blockages of the peripheral arteries, usually those in the legs and pelvis. The most common symptoms are pain, cramping and tiredness in the leg or hip muscles when walking or climbing stairs symptoms that go away during rest. "The bottom line is that among those with lower extremity PAD, women have faster declines in mobility and functional performance compared to men," said study author Mary M. McDermott, a professor of medicine.

"This may be related to gender differences in calf muscle, as women tend to have less calf muscle compared to men," McDermott added. She and her colleagues report their findinsg in the Feb. 8 issue of the Journal of the American College of Cardiology. Both the researchers and the American Heart Association note that an estimated 8 million American men and women are affected by lower extremity PAD, with disease prevalence being split about equally across genders. To examine whether disease progression differs among men and women, between 2002 and 2009 McDermott and her team tracked the progress of 380 male and female patients with PAD of the legs in the Chicago area.

All the participants were 59 and older. Over a four-year period, annual mobility assessments were conducted during which each patient was asked to complete a quarter mile, six-minute walk, as well as a four-minute speed test, to observe the development of disability. Changes in calf muscle measurements and characteristics were also noted, alongside knee extension strength. Overall, the research team determined that after adjusting for age, women fared more poorly than men over the course of the study. As the study period unfolded, they noted that women ended up walking less per week and had more difficulty walking the quarter-mile.

More Kids Who Play Basketball Suffering Head Injuries

Children's basketball may be getting rougher or the kids may be bigger, but either way the number of head injuries is soaring, researchers report. "Although the total number of injuries decreased during the study period, the number of traumatic brain injuries increased by 70 percent," said study author Lara McKenzie, of the Center for Injury Research and Policy at Nationwide Children's Hospital in Columbus, Ohio. "These injuries are exceedingly high in this popular sport," she added. "This is cause for alarm." McKenzie thinks the increased size of players is one factor in the increase in concussions. Another is that the game has become more competitive, she said. Why total injuries have gone down by 20 percent over the 11 years covered by the study is not clear, McKenzie added.

"We don't want to discourage kids from physical activity. We don't want to discourage kids from playing basketball, either," she said. "But we need to recognize that there are some inherent risks in any activity." McKenzie added that the problem of traumatic brain injury needs to be addressed. "Maybe we need to do more education of coaches, athletes and parents to recognize the signs of concussion and help to prevent them," she said. The findings are published in the Sept. 13 online edition of the journal Pediatrics. For the study, McKenzie's team used data from 1997 to 2007 from the U.S. Consumer Product Safety Commission's National Electronic Injury Surveillance System to estimate the number of children injured while playing basketball.

Over the study period, the researchers found an estimated 4,128,852 children were treated in emergency rooms for injuries sustained while playing the sport. That's 375,350 every year. While the total number of injuries went down over the study period, traumatic brain injuries increased 70 percent, the researchers found. The most common other injuries were sprains in the legs 30.3 percent, particularly of the ankle. Boys were more likely to suffer cuts, fractures and dislocations, while girls were more likely to suffer concussions and knee injuries. Children 15 to 19 years of age were three times more likely to injure their knees and ankles, while younger children, aged 5 to 10, were more likely to suffer concussions, fractures and dislocations, the study found.
