[Orthogonal factor analysis on metabolic syndrome].

To elucidate the principal of orthogonal factor analysis, using an example of factor analysis of metabolic syndrome. The basic structures and the fundamental concepts of orthogonal factor analysis were introduced and data involving 1877 women aged of 35-65 years, selected from a cross-sectional study, which was conducted in 1998 - 2001 in Shanghai, were included in this study. Factor analysis was carried out using principle components analysis with Varimax orthogonal rotation of the components of the metabolic syndrome.

[Serum lipid profile changes of the adults in Shanghai communities].

Objective: To explore the adult lipid profile of Huayang community from 1998 to 2000 and Caoyang communities in 2001.

Methods: Representative serum samples of 5628 adults (aged 20 - 95 years) were obtained in Huayang and Caoyang communities during 1998.9 and 2001.

[A comparison of the application of two working definitions of metabolic syndrome in Chinese population].

Objective: To compare the significance of the application of the working definition for metabolic syndrome (MS) proposed by the World Health Organization (WHO) in 1999 and the one proposed by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (ATP III) in 2001.

Methods: Data of 2048 subjects, aged 20-74, 896 males and 1152 females, with complete laboratory data, including plasma glucose, lipid profile, blood pressure, serum insulin, urine albumin and creatinine, were gathered from the data of baseline survey on obesity and its co-morbidities conducted in Huayang and Caoyang communities, Shanghai, from 1999 to 2001. MS was diagnosed according to these two definitions respectively.

[Relationship between the prevalence of microalbuminuria and components of metabolic syndrome in Shanghai].

Objective: To study the relationship between the prevalence of microalbuminuria and components of metabolic syndrome in Shanghai.

Methods: A total of 3532 Shanghai Chinese (men 1622, women 1910) aged over 20 years were included. Body mass index (BMI), blood pressure, fasting plasma glucose, lipid profile and plasma insulin concentrations were measured in all subjects.
