Evaluation on the prevalence of metabolic syndrome and index of insulin resistance in the population screened by oral glucose tolerance test (OGTT) / 解放军医学杂志

ABSTRACT

Objective To investigate the prevalence of metabolic syndrome (MS) and its risk factors in the population of age between 21 to 78 years in Beijing, and to study the clinical significance of evaluation of MS and hyperinsulinaemia by the use of waist circumference and body mass index (BMI). Methods A standard questionnaire and 75g oral glucose tolerance test (OGTT) were used in the investigation. All the data, including plasma glucose (fasting blood glucose level and postprandial glucose level), blood levels of insulin, blood lipid, blood uric acid, and creatinine, as well as height, weight, waist circumference (WC), blood pressure, body mass, were determined or measured. Obesity was defined by WC and BMI value. The incidence of obesity complicated with two abnormal metabolic disorders (IDF), as well as hyperinsulinaemia in these subjects, were analyzed. Results The prevalence of obesity as determined by WC and BMI were 20.6% and 41.5%, respectively, in the said popalation of Beijing (P0.05) in subjects of obesity complicated with two other metabolic abnormality as defined by WC and BMI criteria, accounting for 1.37% and 3.13% of the whole investigated population (P
