In 2002, a survey on Chinese people's diet and health found that more than 18 percent of the Chinese older than 18 have high blood pressure.

According to Wang, the number of patients nationwide has also increased from less than 100 million in 1991 to 260 million in 2012.

The National Center for Cardiovascular Disease started a new national survey in 2012. Though it is not yet completed, the prevalence of high blood pressure will probably hit a new high, Hu said.

The communities are the "main battlefield" to help treat the huge number of patients, he said.

Zhanlanlu Community Health Center in Beijing is among the first of its kind in China to carry out high blood pressure monitoring and prevention advocacy.

Chang Shuling, director of the center, said the community has sponsored regular lectures and free consultations to persuade people to change unhealthy lifestyles and help patients manage their blood pressure.

She said there are more than 20,000 people in the community living with high blood pressure, accounting for more than 22 percent of its population.

"The center and its seven healthcare stations are tracking the condition of 13,000 patients by measuring their blood pressure at least four times a year and offering them prescriptions to control blood pressure," said Chang, who has worked at the center for 16 years.

She admitted that the disease is becoming more common in the community and patients are getting younger.

"Most of the patients coming to us are retirees, but in recent years we started to have people in their 20s and 30s coming to us for treatment, as they tend to lack exercise, consume fatty foods, stay up late at night and are usually under great pressure from work," she said.

"One of our tasks is reducing the risks among this kind of people by intervening and changing their unhealthy habits."
