Characteristics of obesity and its related disorders in China.

Obesity is a medical condition with excess body fat accumulation to the extent which leads to serious health consequences. Abdominal obesity, also known as central obesity, refers to the presence of excess fat in the abdominal area. Obesity, especially abdominal obesity, contributes to many metabolic disorders including metabolic syndrome (MetS), type 2 diabetes (T2DM) and cardiovascular diseases (CVD). The incidence of obesity has increased dramatically in recent years worldwide. In China, more than one-third of adults are overweight or obese and 10%-20% of all adults are affected by MetS. The pathogenesis underlying the abdominal obesity remains unclear. The ultimate health outcome of obesity and its related metabolic disorders haveprompted physicians to take aggressive treatments (lifestyle changes, pharmacological interventions and surgical therapies) before a serious consequence becomes clinically apparent. In this review, we discuss the prevalence, pathogenesis and clinic features of obesity in China.
