Mortality associated with care-giving and care-giving related stress: a data linkage study

Many studies have suggested that caregiving has a detrimental impact on health, thus the terminology ‘caregiver burden’ and ‘caregiver stress’. However, these conclusions are challenged by research (including from NILS and ONS-LS) that finds evidence of a comparative survivorship advantage. It is possible that while the overall effect on mortality may be beneficial, there may be sub-groups of carers who are at a higher mortality risk. The differentiating factor may be the amount of stress experienced, as Fredman et al. (2010) found high-stress caregivers had a higher mortality risk compared to both non-carers and low stress caregivers.
Approximately 17% of the Northern Ireland population provides informal care and understanding who are most at risk of negative outcomes is vital for ensuring the health and well-being of caregivers. This study will utilize data from the Northern Ireland Mortality Study, which holds mortality information on all residents enumerated in the 2011 Census. By analysing mortality after the Census (until end 2012) we can determine risk based on both care-giving status and psychological health as identified in the 2011 Census.
This project will aim to determine:
(i) The risk of all-cause mortality based on caregiving status and psychological health
(ii) The risk of all-cause mortality given caregiving responsibility, i.e. no of hours in caring role and specific caring duties either to a child with illness or disability, or to a spouse with dementia, illness or disability.
