結果發現年齡是影響體位（BMI、腰臀比、體脂肪）的主要因素。女性對於自己的體型，比男性不滿意也較男性嚴苛，所以女性進行體重控制（69.9﹪）也比男性多。覺得自己體型越胖（74.3﹪），越會進行體重控制，而且是進行減重。進行體重控制民眾在體重控制的利益性、肥胖對健康和對形象的威脅認同都高於沒有進行體重控制。 The 304 residents in Kao-Fu Li of Hwan-lain city were recruited in this study to find the influences of their demographic characteristics, body size, self-image, beliefs about weight control upon their weight control practices.
