【Abstract】 With the improvement of living conditions in China,the prevalence rate of obesity is going up.Obesity,of which the prevention is principal,has been found to be a main factor initiating diseases related to better living conditions(DRBLC),such as hypertension,coronary heart disease(CHD),non-insulin dependent diabetes mellitus(NIDDM)and hyperlipidemia.World Health Organization(WHO)has recommended a body mass index (BMI) to judge whether he or she is fat or not.Since the distributions of the BMI in various countries differ,it is important to get a clear understanding of the distribution of Chinese BMI.Based on a survey in a community in Shanghai during 1997-1998,this paper studies the distribution of the MBI in this community,and fits the density function by a model of contaminated normal distribution.更多还原
