Although exposure to thin-ideal females in the media has been shown to increase women's body dissatisfaction, only a few studies have examined the effects of comparisons with peers, and no prior work has studied the effects of peer comparisons in a naturalistic setting or on objective behavior.
Female undergraduates (n = 45) in a campus gym who exercised on a target apparatus were assigned to have a fit-peer, unfit-peer, or no-peer (control) exercise within their view on a nearby apparatus. Objective time spent exercising and body satisfaction reports were collected.
Exposure to a fit peer had undermining effects on women's body satisfaction and exercise duration, whereas an unfit peer produced no compensating greater body satisfaction but did elicit longer exercise duration relative to controls.
Incidental comparisons with fit versus unfit peers can affect women's body satisfaction and fitness-related behavior in a naturalistic setting.
尽管有研究表明，接触媒体中宣扬瘦身理念的女性会增加女性对自身身材的不满，但只有少数研究考察了与同龄人比较的影响，而且之前没有研究在自然环境中或对客观行为研究同龄人比较的影响。
在校园健身房中，在目标器械上锻炼的45名女大学生被分配到在其视野范围内的附近器械上与身材好的同龄人、身材不好的同龄人一起锻炼，或独自锻炼（对照组）。收集锻炼的客观时长和身体满意度报告。
接触身材好的同龄人会削弱女性的身体满意度和锻炼时长，而接触身材不好的同龄人虽然不会带来更高的身体满意度，但相对于对照组，确实会延长锻炼时长。
在自然环境中，与身材好或不好的同龄人进行偶然比较会影响女性的身体满意度和与健康相关的行为。
