China's National Health Commission (NHC) published its first set of guidelines to standardize the diagnosis and treatment of obesity, with more than half of China's adults already overweight and obese, and the rate expected to keep rising.

The guidelines, made public on October 17, come as China experiences an upward morbidity trend of its overweight and obese population. The rate of overweight or obese people could reach 65.3% by 2030, the NHC said.

"Obesity has become a major public health issue in China, ranking as the sixth leading risk factor for death and disability in the country," the guidelines said.

China is facing a twin challenge that feeds its weight problem: In a modernizing economy underpinned by technological innovation, more jobs have become static or desk-bound, while a prolonged slowdown in growth is forcing people to adopt cheaper, unhealthy diets.

Job stress, long work hours and poor diets are growing high-risk factors in the cities, while in rural areas, agriculture work is becoming less physically demanding and inadequate healthcare is leading to poor screening and treatment of weight problems, doctors and academics say.

The guidelines provide guidance and regulations including in clinical nutrition, surgical treatment, behavioral and psychological intervention, and exercise intervention for obesity, Zhang Zhongtao, director of the guideline drafting committee and deputy head of Beijing Friendship Hospital, told the official Xinhua news agency.

China's NHC and 15 other government departments in July launched public awareness efforts to fight obesity. The campaign, set to last for three years, is built around eight slogans: "lifelong commitment, active monitoring, a balanced diet, physical activity, good sleep, reasonable targets and family action."

Health guidelines were distributed to primary and secondary schools in July urging regular screening, daily exercise, hiring nutritionists and implementing healthy eating habits – including lowering salt, oil and sugar.

Obesity in China is an "unintended consequence of improving living standards in the country," Xinhua said, after China struggled for centuries to feed its population and under-nourishment was a genuine concern for many families before the reform and opening-up in the late 1970s.
