The aims were to test relationships between bulimic eating disorder behaviors, and measures of quality of life, and to replicate previous findings with respect to their prevalence and distribution in a representative sample.
Data were obtained from 3010 interviews of a randomly selected sample of 4400 adult households. Quality of life was assessed with the SF-36 Health Status Measure and the Australian Quality of Life Survey.
Eating disorder behaviors were associated with significantly lower quality of life scores. On MANOVA, regular current binge eating explained 23% (p < 0.001) of the variance in SF-36 physical and mental health component scores, and extreme weight control behaviors explained 5% (p = 0.001). The main findings of the former South Australian survey were replicated. The mean duration of behaviors since onset was 6.6 (SD, 9.2; median 3) years.
Eating disorder behaviors were associated with poorer quality of life and were often chronic.
旨在测试暴食症饮食失调行为与生活质量指标之间的关系，并在一个具有代表性的样本中重复先前关于其患病率和分布情况的研究结果。
数据来自对4400个成年家庭随机抽取的样本进行的3010次访谈。生活质量通过SF-36健康状况量表和澳大利亚生活质量调查进行评估。
饮食失调行为与显著更低的生活质量得分相关。在多变量方差分析中，当前经常暴饮暴食解释了SF-36身心健康成分得分中23%（p < 0.001）的方差变异，而极端体重控制行为解释了5%（p = 0.001）。南澳大利亚州先前调查的主要结果得到了重复。自发病以来行为的平均持续时间为6.6年（标准差为9.2；中位数为3年）。
饮食失调行为与较差的生活质量相关，且往往是慢性的。
