Abstract

Obesity has become a global epidemic and is a major risk factor for the development of metabolic abnormalities and cardiovascular disease. With the rapid economic development in China, the prevalence of overweight and obesity has been rising, estimated 22.4% of the adult population is overweight and 3.01% is obese in 1990s. It is categorized as abdominal obesity if fat is accumulated in the abdomen. Theoretically, abdominal obesity should be determined by visceral adipose tissue (VAT) precisely measured by magnetic resonance imaging (MRI) or computerized tomography (CT) scanning. While, waist circumference is widely used clinically to estimate the abdominal fat for its convenience and strong correlation with VAT. The waist circumference increased with aging in Chinese population and was quite similar in men and women especially in the subgroup with age over 60 years. Based on a cross-sectional survey, the accumulation of visceral fat at the level of visceral fat area (VFA) over 80 cm2 in Chinese linked with high prevalence of the metabolic syndrome (MetS). The corresponding waist circumference cut-offs were 87.5 cm in men and 84.3 cm in women. Therefore, it was demonstrated that the optimal cut-offs of waist circumference were 90 cm in men and 85 cm in women. Another prospective study demonstrated that the MetS based on the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults (JCDCG) definition was a significant predictor for the development of CVD in total subjects. This study furthermore confirmed that the waist circumference cut-offs with 90 cm in men and 85 cm in women were more suitable than the IDF recommended in Chinese population.
