本研究目的在探討大學新生身體質量指數與代謝症候群危險因子相關性之研究。採橫斷性之研究，以95、96學年參與健康檢查大學新生爲研究對象，共1096名。以國民健康局2004年訂定的「代謝症候群」定義爲標準。以描述統計、百分比及卡方檢定(Chi-square test)分析，α=.001。研究結果一、代謝症候群危險因子中，血壓及診斷有代謝症候群異常者，96學年低於95學年；三酸甘油脂、總膽固醇、肝功能(GOT、GPT)、腎功能(BUN)及尿酸(UA)危險因子異常值，96學年皆高於95學年。二、以BMI分類在代謝症候群危險因子中，三酸甘油脂、血壓值、血糖、總膽固醇、尿酸、GOT、GPT值皆達顯著差異(p<.001)。體重「過重」者，三酸甘油脂、血糖及尿酸值異常者的比例，較正常者高；體重「肥胖」者，僅在血糖值異常者的比例，較正常者高。三、在診斷代謝症候群比例女性顯著高於男性(p<.001)；有代謝症候群者，三酸甘油脂、血壓值、血糖值及總膽固醇等指標異常者，亦達顯著差異(p<.001)。結論：藉由健康檢查瞭解大學新生體重「過重」及「肥胖」比例約爲總人數28.5%，有相關代謝症候群者達總人數31.9%。顯見「肥胖」及相關代謝症候群疾病已是大學生健康的一大隱憂，值得學校相關衛生單位重視。

The purpose of this study is to body mass index and examine risk factors of metabolic syndrome in university freshmen. A cross-sectional design was used to investigate 1096 university freshmen. Who participated in the health examination of 95 and 96 academic years in integrated screening test. The diagnosis of metabolic syndrome was based on definitions issued by Bureau of Health Promotion, Department of Health in 2004. Data were analyzed using by descriptive statistics, chi-square test and the percentage. The criterion for significance for all comparisons was p<.001. Results: 1. Of all the risk factors for metabolic syndrome, the abnormal fasting blood pressure and with metabolic syndrome levels 96 academic less than 95 academic, Other triglycerides, total cholesterol, GOT, GPT, BUN and UA risk factor for abnormal value, levels 96 academic higher than 95.2. The of BMI standards and classification of the metabolic syndrome risk factors, triglycerides, blood pressure, sugar, cholesterol, uric acid, GOT, GPT values were statistically significant differences (p<.001). A higher percentage of overweight triglycerides, sugar and uric acid value of the abnormal ratio are higher than normal and obesity is sugar level in the ratio of higher than normal with metabolic syndrome. 3. The metabolic syndrome and the relationship between variables, women diagnosed with than of men, showed significant improvement of (p<.001). The diagnosis of metabolic syndrome, triglycerides, blood pressure, sugar and total cholesterol, showed significant improvement of (p<.001). Conclusion: The health examination by the understanding of overweight and obesity, showed the of 28.5%, metabolic syndrome-related diseases showed the of 31.9%. The obesity and metabolic syndrome related diseases for the college student's health problem, school administrative, can not be ignored.
