The effect of experimental manipulations of the thin beauty ideal, as portrayed in the mass media, on female body image was evaluated using meta-analysis.
Data from 25 studies (43 effect sizes) were used to examine the main effect of mass media images of the slender ideal, as well as the moderating effects of pre-existing body image problems, the age of the participants, the number of stimulus presentations, and the type of research design.
Body image was significantly more negative after viewing thin media images than after viewing images of either average size models, plus size models, or inanimate objects. This effect was stronger for between-subjects designs, participants less than 19 years of age, and for participants who are vulnerable to activation of a thinness schema.
Results support the sociocultural perspective that mass media promulgate a slender ideal that elicits body dissatisfaction. Implications for prevention and research on social comparison processes are considered.
运用荟萃分析评估大众媒体所描绘的纤瘦审美理想的实验性操控对女性身体意象的影响。
来自25项研究（43个效应量）的数据用于检验纤瘦理想的大众媒体形象的主效应，以及既有身体意象问题、参与者年龄、刺激呈现次数和研究设计类型的调节效应。
观看纤瘦媒体形象后，身体意象显著比观看平均身材模特、加大码模特或无生命物体的形象后更消极。这种效应在被试间设计、年龄小于19岁的参与者以及易激活瘦素模式的参与者中更强。
结果支持社会文化观点，即大众媒体传播一种引发身体不满的纤瘦理想。同时考虑了对社会比较过程预防和研究的启示。
