Pulmonary disease a big health threat
China has nearly 100 million people with chronic obstructive pulmonary disease, placing the respiratory condition among the country’s biggest public health challenges, a national study has found. Starting in mid2012, the three-year nationwide study covered nearly 51,000 participants ages 20 or older. The findings were published recently in the international medical journal The Lancet. The study found that 8.6 percent of participants had the disease, with the elderly and smokers at higher risk. It was led by Wang Chen, a respiratory disease expert and president of both the Chinese Academy of Medical Sciences and Peking Union Medical College.
