| Summary: | 碩士 === 中國醫藥大學 === 醫務管理研究所 === 93 === Previous studies indicate that metabolic syndrome increases the incidence and mortality of cardiovascular disease, type 2 diabetes mellitus, hypertension and stroke etc. Therefore, the syndrome causes great damage to general public health. The prevalence of metabolic syndrome increases as westernized life style becomes popular in Taiwan nowadays. There are only few studies about metabolic syndrome being conducted in Taiwan. In addition, no representative and population-based study in Taichung city up to now. Therefoe, the objectives of the study are to estimate the prevalence of metabolic syndrome and to explore its associated factors among Taichung residents aged forty years old and over. This is a cross-sectional study. There were 4,278 subjects being sampled and 1,374 people participating in this study during October 16, 2004 to May 7, 2005.
This study adopted the guidelines of National Cholesterol Education Program III (NCEP ATP III) for Europe and Asia, World Health Organization (WHO), and the department of health, Executive Yuan, Taiwan to define the metabolic syndrome. The kappa values of agreement on metabolic syndrome between four definitions according to different criteria are from 0.57 to 0.97; the range of prevalence for metabolic syndrome defined by four criteria among Taichung residents aged forty years old and over is 18.20%-24.54%; and after adjustment by Taichung 2003 population, the prevalence of metabolic syndrome ranged from 17.65% to 24.38%. The significant risk factors of metabolic syndrome are not completely the same for different criteria, and these risk factors included gender, age, marriage status, education level, family income, nutrition intake (including carbohydrate, cholesterol, calorie), activity level of occupation, habits of smoking, drinking and betel quid, time of watching TV and family disease history of gout and type 2 diabetes mellitus. Besides, the associated risk factors in women included menopause, procreation experiences, hysterectomy experiences and taking oral contraceptive pills experiences. Factor analysis identifies three to four factors underlying clustering of the basic variables constituting the metabolic syndrome.
This study shows that the prevalence of metabolic syndrome among Taichung residents aged forty years old and over is not low and the government must pay more attention to this health problem that causes great damage to public health. In addition, the department of health or the healthcare providers sholud aim at different groups to provide different associated health-care consultation activities, propagandas and suggestions for disease prevention. On the other hand, the agreement of metabolic syndrome under different definitions exists high variation; this will require future studies to investigate which definition is more related to increase risk of occurrence and mortality of CVA or cardiovascular disease.
