Obesity is now a crucial health problem worldwide. Even with the abundant methods of dietary control, exercise intervention, drug therapy and bariatric surgery for the treatment and prevention of obesity, the prevalence is still growing rapidly. The updated understanding of obesity and its complications is desperately needed. In recent years, investigators have been focusing on sleeping health care in the prevention and treatment of obesity. Sleep restriction and eating disorders during sleep time contribute critically to obesity and its complications, while obstructive sleep apnea hypopnea syndrome(OSAHS) and some other sleeping disorders result from obesity. More domestic and systemic study is required about sleeping health in obesity prevention and management in China.
