检查与频繁节食相关的心理和行为变化。与nondieters相比，频繁的节食者被假设为显示出更多的不良心理变化和增加使用不健康的体重控制行为，但可能更健康的饮食和锻炼行为的变化，在三年的观察期.METHODSA前瞻性研究的女学生，在7-10年级在基线完成了一项健康行为调查，每年一次在学校共三年。与非节食者相比，经常节食者的身体不满意度和对瘦的渴望、自我诱发的呕吐、泻药的使用、减肥药的使用和酒精的使用显著增加，而身体外观和自我概念显著降低。五个EDI分量表，8个自尊分量表，体重波动，饮食摄入量和身体活动模式的分数变化并没有显着不同，随着时间的推移节食status.CONCLUSIONDieting可能反映了一般模式的不健康的行为在青春期，而不是作为一个因果因素，促进心理困扰。
PURPOSEPsychologic and behavioral changes associated with frequent dieting were examined. Compared to nondieters, frequent dieters were hypothesized to show more adverse psychologic changes and increased use of unhealthy weight control behaviors, but possibly healthier eating and exercise behavior changes, over the three-year period of observation.METHODSA prospective study of female students, in grades 7–10 at baseline completed a health behavior survey in school once a year for a total of three years.RESULTSRestrained eating, body dissatisfaction and drive for thinness, self-induced vomiting, laxative use, diet pill use, and alcohol use, significantly increased, and physical appearance and self-concept significantly decreased among frequent dieters, compared to non-dieters. Changes in scores on five EDI subscales, eight self-esteem subscales, weight fluctuations, dietary intake, and physical activity patterns did not significantly differ over time by dieting status.CONCLUSIONDieting may reflect a general pattern of unhealthy behaviors adopted in adolescence, rather than act as a causal factor in promoting psychologic distress.
