肥胖是已開發與開發中國家流行的主要慢性病之一。本研究之目的在探討成人肥胖與肥胖型態之盛行率與其對血壓、血糖及血脂之影響。樣本來自於南部某醫學中心572位20歲以上參與健康檢查者，經由體型測量與血液生化檢查，分析男女年齡別肥胖型態之盛行率與其與血壓、血糖及血脂之關係。結果顯示男女肥胖盛行率分別為24.2％與23.3％，女性肥胖比率隨年齡增加而增加，年性則以41至50歲間肥胖比例最高，而後比例隨年齡增加而下降。女性腹胖比例約為一成，幾乎完全集中在60歲以上的婦女；男性腹胖比例約為三成，約有30％至35％的40歲以上的男人有腹胖的現象。肥胖及肥胖型態與高密度膽固醇、三酸甘油脂、飯前血糖、舒張壓、收縮壓、動脈硬化指數有相關。當成人有肥胖現象時，醫護人員應建議民眾控制體重，定期檢測血脂、血壓、血糖等相關之因子，以預防心血管疾病及新陳代謝症候群之發生。

　　　　　The obesity has become one of the major epidemic disease in many developing and developed countries worldwide. We presented the prevalence of obesity and examined the association of obesity with blood lipoprotein, blood sugar, and blood pressure among 572 adults who attended a physical check-up program in a medical center in southern Taiwan. The prevalence of obesity was 24.2% for men and 23.3% for women, respectively. This prevalence increased as age increased among women, while it peaked at the age between 41 and 50 among men and decreased as age increased thereafter. The prevalence of abdominal obesity was about 30% for men and around 10% for women, and the cases mainly were from women in the age group of over 60. About 30-35% of the men who were aged over 40 had abdominal obesity. Obesity was found to be associated with several test results, including high density lipoprotein, triglyceride, blood sugar before meals, blood pressure, and index of arteriosclerosis. The obese adults are advised to control their body weight and regularly monitor their blood lipoproteins, sugars, and pressures to prevent the occurrence of cardiovascular and metabolic diseases.
