3．In the past years the popularity of rock climbing has greatly increased，and so has the number of injuries．It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year．Study findings revealed a 65 percent increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2011．
The study，published in the online issue of the American Journal of Preventive Medicine，found that about 40，000 patients were treated in US emergency departments for rock climbing-related injuries between 1991and 2011．The most common types of rock climbing-related injuries were fractures （骨折） and sprains （扭傷）．The ankle was the most common body part to be injured （40 percent）．Climbers in the study ranged in age from 2 to 74，with an average age of 26．The study also found that women took up a quarter of the injuries．
Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall．The severity of fall-related injuries had a lot to do with the height of the fall．Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower．
"We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury，"explained the study author Lara McKenzie，PhD，director at the Center for Injury Research and Policy at Nationwide Hospital．"This trend，combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries，demonstrates the need to increase injury prevention efforts for climbers．"
