身材不滿意之決定因子及身材不滿意對瘦身意圖的影響：以女大學生為例

The Determinants of Body Dissatisfaction and the Influence of Body Dissatisfaction on Weight-Loss Intention: A Study on Taiwanese Female College Students

目的：本研究探討女大學生對自我身材不滿意的因素與其影響。方法：研究設計以橫斷面調查方式針對台灣地區女大學生進行調查，運用多階集群抽樣方法收集607份有效問卷，並以結構方程式進行假設驗證。結果：(1)身體質量指數、社會批評會影響受訪者對胸部的不滿意；(2)身體質量指數、社會批評、向上社會比較及接收媒介對纖細身材的報導會影響女大學生對胸部以外其他部位的不滿意；(3)受訪者對其胸部或胸部以外其他部位的不滿意程度會影響其減肥意願。結論：校園衛生教育實務者進行身體意象衛教資訊設計時，應考慮身體質量指數、社會批評、向上社會比較及媒介對纖細身材的報導內容對大學女生身材滿意度的影響與身材滿意度對減重意願的影響。

Purpose: This cross-sectional study attempts to clarify the determinants and the consequence of body dissatisfaction among Taiwanese female college students. Method: A cluster sampling was used to recruit respondents from 8 universities. Finally, a total of 607 respondents completed the questionnaire. Results: The results showed that BMI and social criticism significantly impacted breast dissatisfaction while BMI, social criticism, upward social comparison, and appearance media exposure significantly influenced body (breast excluded) dissatisfaction. Also, body dissatisfaction significantly predicted weight-loss intention. Conclusion: This study suggests that on-campus health education designers need to consider the impact of BMI, social criticism, upward social comparison, and appearance media exposure on body dissatisfaction and the influence of body dissatisfaction on weight-loss intention as they attempt to design a health education campaign.
