This study investigated how exposure to non-body focused others (i.e., those who are not preoccupied with their body weight/shape or appearance) and exposure to body focused others uniquely affect young women's eating and body image over a week, within a day, and from one day to the next. For seven consecutive days, 92 female college students completed nightly online questionnaires about their daily experiences. Between-persons, multilevel modelling revealed that higher average levels of exposure to non-body focused others over the week uniquely predicted greater intuitive eating, greater body appreciation, and less dietary restraint, whereas higher average exposure to body focused others predicted these outcomes in the opposite direction. Within-persons, exposure to body focused others did not predict eating and body image, but exposure to non-body focused others did. On days when women had more exposure to non-body focused others than their personal average level or than the previous day's level, eating and body image were better. These findings are the first to suggest that independent of exposure to body focused others, level of exposure to non-body focused others - within and across days - contribute positively to eating and body image.
本研究旨在探究非关注体型人士（即那些不专注于自身体重/体型或外貌的人）和关注体型人士的接触分别如何在一周内、一天内以及一天与另一天之间对年轻女性的饮食和身体意象产生影响。在连续七天的时间里，92 名女大学生每天晚上都要在线填写问卷，报告他们的日常经历。跨人群多层次模型分析显示，一周内平均接触非关注体型人士的水平越高，预示着直觉饮食、身体欣赏和饮食抑制的水平越高，而平均接触关注体型人士的水平越高，则预示着这些结果呈相反方向。个体内，接触关注体型人士并不预示着饮食和身体意象，但接触非关注体型人士则预示着这些结果。当女性接触非关注体型人士的水平高于个人平均水平或前一天的水平时，其饮食和身体意象会更好。这些发现首次表明，独立于关注体型人士的接触，接触非关注体型人士的水平——在个体内和个体间——对饮食和身体意象有积极的影响。
