To identify the age of onset of eating disorder behaviours (EDBs) and weight/shape overvaluation in a community sample and to evaluate the association between the age of onset and duration of EDBs with health related quality of life (HRQoL).
Data were extracted from the 2008/2009 Health Omnibus Survey (HOS). In 2008, 3034 and in 2009, 3007 participants from a randomly selected sample of households in the Australian population were interviewed for current and age of onset of EDBs. In 2008, mental and physical HRQoL was assessed with the Short Form 12-item instrument (SF-36-2). In 2009, role impairment was assessed with reported days out of role in the past month.
There were no significant associations between ages of onset of EDBs with the overall summary measures of physical or mental HRQoL. There was a significant positive association between the duration of EDBs with role impairment. The age of onset of EDBs had a significant negative association with physical HRQoL subscales of SF-36-2 but effect sizes were small.
The age of onset of EDBs did not appear to have a significant impact on overall HRQoL measures but duration of symptoms impacted on current role function.
在社区样本中确定饮食障碍行为（EDB）和体重/体型过度重视的发病年龄，并评估 EDB 发病年龄和持续时间与健康相关生活质量（HRQoL）之间的关系。
数据取自 2008/2009 年健康综合调查（HOS）。2008 年，对澳大利亚人群中随机抽取的家庭样本中的 3034 名参与者和 2009 年的 3007 名参与者进行了当前和 EDB 发病年龄的访谈。2008 年，采用 12 项简短形式量表（SF-36-2）评估心理健康和生理 HRQoL。2009 年，通过报告过去一个月中角色缺失的天数来评估角色受损情况。
EDB 发病年龄与生理或心理健康 HRQoL 的总体综合指标之间无显著相关性。EDB 的持续时间与角色受损之间存在显著的正相关关系。EDB 的发病年龄与 SF-36-2 的生理 HRQoL 子量表呈显著负相关，但效应大小较小。
EDB 的发病年龄似乎对整体 HRQoL 指标没有显著影响，但症状持续时间会影响当前的角色功能。
