健康的體位與多種慢性疾病的防治有著密不可分的關係,肥胖更是全球性的議題。本文綜合國內外相關文獻,針對肥胖、體重過輕等相關體位問題在不同年齡、性別的影響及其因應策略加以回顧。我國男性成人過重與肥胖盛行率分別為30.5%與19.2%而女性為21.3%與13.4%,過去十年來男性肥胖的盛行率比起女性明顯上升,而國人攝取過多的油脂量及不運動都是肥胖的主因。女性肥胖盛行率在停經前低於男性,而在停經後卻高於男性,因此婦女在停經前後就應調整飲食及保持運動習慣,才能維持健康體位,進而預防慢性病的發生。此外,兒童及青少年肥胖也日漸受到矚目,父母親若有肥胖問題或母親在懷孕時有妊娠糖尿病等都會增加兒童及青少年肥胖的機率,故此族群的健康行為更應特別注意。另外,青少無因為過分注意身體形象而造成體重過輕也是近年來受到關注的議題,如何透過社會、學校的介入,培養群體間正確的飲食態度和行為以減少青少年的飲食障礙是值得思考的問題。健康體位的推行,需要充分運用社區、學校、職場及醫院的資源,配合良好的公共政策,才能讓全民申健康。
As a risk factor of various chronic diseases, obesity has become a worldwide problem. In Taiwan, the prevalence of being overweight and obesity are 30.5% and 19.2% in men, and 21.3% and 13.4% in women, respectively. The increase in the obesity prevalence has been more profound in men than in women compared to prevalences 10 years ago. A high-fat diet and sedentary lifestyle are responsible for the increases in obesity. Childhood and adolescent obesity is also another major problem in Taiwan. A family history of parental obesity and maternal gestational diabetes are important risk factors for childhood and adolescent obesity. In addition, being underweight is also a rising problem, since an excessively thin body image has been overemphasized in adolescents. Therefore, to attain a healthy weight status, we need a good healthcare policy from the government and must adequately utilize resources from communities, schools, workplaces, and hospitals.
