肥胖會增加代謝症候群的風險，是年輕人不可忽略的健康問題，也是重要的公共衛生議題。本研究目的在瞭解青春後期（15～18歲）與成年早期（19～25歲）的學生在肥胖與代謝症候群的狀況，及探究正常體重與肥胖在代謝症候群指標上的差異。採橫斷式研究設計，以某科技大學醫護學院之新生為研究對象，共收取有效樣本730位，資料收集包括個案基本屬性、身體質量指數、腰圍、血壓、空腹血糖及血脂。肥胖及代謝症候群定義以中華民國行政院衛生署及國民健康局的標準為依據。結果顯示符合代謝症候群定義者有57人（7.82%），青春後期比成年早期的學生有較高比率的體重過重、肥胖及多項代謝症候群異常指標；體重過重及肥胖者比起正常體重者，有較多代謝症候群異常指標及較高的代謝症候群風險。依據研究結果，建議技專院校的新生健康檢查應將腰圍及高密度脂蛋白膽固醇納入常規檢測，以早期評估與確認學生在肥胖、代謝症候群的相關風險。學校衛生護士應透過介入措施，加強減少肥胖學生的腹部脂肪分佈，並防止體重增加，以降低代謝症候群的發生。

Obesity increases the risk of metabolic syndrome and represents a significant health problem with youth that must be addressed by public health authorities. The purposes of this study were to investigate differences in obesity and metabolic syndrome between post-puberty (15-18 year old) and early adulthood (19-25 year old) students, and to explore differences in metabolic syndrome between normal weight and obese subjects. A cross-sectional study was conducted on 730 medicine-nursing freshmen who received a health examination at a university. Demographic data, body mass index, waist circumference, blood pressure, fasting plasma glucose and lipid levels were collected. The obesity and metabolic syndrome criteria used were those published by the Department of Health and Bureau of Health Promotion, Taiwan. Results show that the metabolic syndrome rate was 7.82% amongst respondents. Post-puberty students scored higher in terms of being overweight, obese and facing multi-component metabolic syndrome than their early adulthood student counterparts. Overweight and obese students faced a higher metabolic syndrome risk as compared to normal weight students. Based on findings, we suggested that both waist and high-density-lipoprotein cholesterol measurement be added to the health examination administered to university freshmen to help detect the risk of obesity and metabolic syndrome as early as possible. Through an intervention program, the school nurses should target the decrease of abdominal fat distribution and prevent excess weight gain for obese students in order to reduce the incidence of metabolic syndrome.
