This proposal addresses healthy ageing and management of dementia. These are significant issues for New Zealand, given increasing life expectancy and lack of cure for dementia, creating pressure on national support systems. Sleep problems are more common with ageing and negatively impact waking function, comorbid disease, and healthcare usage. Sleep problems are among the most challenging symptoms associated with dementia, having implications for living independently and well. This project builds knowledge regarding the impact of sleep problems on health and well-being of older people, their families, and for aged care services. Two studies analyse existing national data sets (2013-2014 New Zealand Health Survey, and assessment forms for residential care). Another two studies explore people’s experiences using focus groups with older Maori and non-Maori, and interviews with carers who have recently transitioned a family member with dementia into care. Findings will identify needs and opportunities for developing sleep-focused strategies and interventions.
