Prospective associations between work stress, allostatic load, and combined modifiable lifestyle behaviours over 12 years in the Personality and Total Health (PATH) Through Life study

The aim of this study is to examine the effect of work stress at baseline on the development of allostatic load at 12-year follow-up, and to determine the extent to which combined modifiable lifestyle behaviours mediate this association using the Australian PATH Through Life study.

The data was collected by a group of researchers across Australian institutions such as University of New South Wales and Australian National University. The data was collected using validated instruments (e.g. questionnaires) at baseline and follow-up periods.

The data will be coded accordingly to address our research aim. The data will be analysed using statistical techniques (latent class analysis and mediation analysis). Latent class analysis will identify the combinations of lifestyle behaviours emerged from the data; mediation analysis will assess whether such combined lifestyle behaviours is a mediator of the association between work stress and allostatic load.

Work stress at baseline may be associated with increased allostatic load at 12 years follow-up and combined modifiable lifestyle behaviours may partially explain the association.
