The study, which provided lung-function screenings for more than 50,990 participants, is the largest survey of COPD across age groups ever conducted in China, said a team of researchers.

COPD, an inflammatory lung disease that causes obstructed airflow into the lungs, is the third leading cause of death in China. It is caused by long-term exposure to irritants in the air, including cigarette smoke. During the past decade, ambient air pollution has become a major public-health crisis in the country while cigarette smoking remains high, especially among men, says, senior author, Dr. Jiang He, Joseph S. Copes Chair of Epidemiology at Tulane University School of Public Health & Tropical Medicine.

"Our research shows that COPD is highly prevalent in the Chinese adult population. The biggest preventable risk factors for the disease are cigarette smoking and air pollution," He says. "Prevention programs and increased efforts to catch COPD early should be public-health priorities in China to reduce COPD-related diseases and deaths."

The study found that men had a higher prevalence (11.9 percent) of COPD than women (5.4 percent). The sex difference was noted among all age groups in the general population and even among those who never smoked.

Based on the lung-function screenings, researchers estimated the total number of individuals aged 20 years or older with COPD in China was 99.9 million in 2015. Of these, 68.4 million were men, and 31.5 million were women.

A team of researchers found that most people with COPD were unaware of their condition, and few had received a pulmonary function test prior to the study. Only 2.6 percent of participants were aware of their condition, and only 12 percent of those found to have COPD reported getting a previous pulmonary function test.

The research team found COPD prevalence increased with age. It was 2.1 percent for individuals aged 20-39 years old compared to 13.7 percent for those aged 40 years or older. The disease was more common for rural residents (9.6 percent) than for those in urban areas (7.4 percent). The same trend was noted among non-smokers.

The research team suspect that those who didn't smoke developed COPD due to other risk factors or environmental exposures such as air pollution, chronic cough during childhood, parental history of respiratory diseases, low body weight and low education.

The study calls for new national public health strategies to prevent COPD that include smoking cessation programs, stricter control of ambient air pollution and biomass use, and COPD screenings for high-risk individuals using pulmonary function tests.

Right after my 40th birthday I was informed by my family doctor after having some chest X-rays that I had mild emphysema. I had smoked for 20 years. I kept smoking and started getting sick about 7 months later. I ended up in intensive care for six days in septic shock from double pneumonia and almost died. The minute I start to walk around my breathing gets bad. Even the oxygen doesn't seem to help. I want to feel good, and alive and energetic besides, I have a 2 years old grandson and I want to watch him grow up. My search for alternative treatments for treating my emphysema eventually led me to some amazing researcher/herbal doctor called Dr Linda[Best Health Herbal Centre] who had made unbelievable advancements in the use of alternative treatments to actually “Reverse” diseases. This same researcher/herbal doctor was providing her patients with herbal supplements that restored the immune system. I followed suit once again purchasing emphysema herbal supplement. After 6 weeks of relentlessly taking of the emphysema herbal supplements twice each day i completely recovered from emphysema! All my symptoms are gone and Remaining positive helped me during this treatment.
