Exploring associations between age of onset and quality of life of people with eating disorder behaviours and weight/shape overvaluation: a general population study

Abstract

Objective:

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).

Method:

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.

Results:

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.

Conclusions:

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.
