Topic: Risk, prevention and care in population studies

Background Determinants for undetected dementia and late-life depression have been not well studied. Aims To investigate risk factors for undetected dementia and depression in older communities. Method Using the method of the 10/66 algorithm, we interviewed a random sample of 7072 participants aged ≥60 years in six provinces of China during 2007-2011. We documented doctor-diagnosed dementia and depression in the interview. Using the validated 10/66 algorithm we diagnosed dementia (n = 359) and depression (n = 328). Results We found that 93.1% of dementia and 92.5% of depression was undetected. Both undetected dementia and depression were significantly associated with low levels of education and occupation, and living in a rural area. The risk of undetected dementia was also associated with 'help available when needed', and inversely, with a family history of mental illness and having functional impairment. Undetected depression was significantly related to female gender, low income, having more children and inversely with having heart disease. Conclusions Older adults in China have high levels of undetected dementia and depression. General socioeconomic improvement, associated with mental health education, targeting high-risk populations are likely to increase detection of dementia and depression in older adults, providing a backdrop for culturally acceptable service development.

Key findings

Results We found that 93.1% of dementia and 92.5% of depression was undetected.
Both undetected dementia and depression were significantly associated with low levels of education and occupation, and living in a rural area.
The risk of undetected dementia was also associated with 'help available when needed', and inversely, with a family history of mental illness and having functional impairment.
Undetected depression was significantly related to female gender, low income, having more children and inversely with having heart disease.
General socioeconomic improvement, associated with mental health education, targeting high-risk populations are likely to increase detection of dementia and depression in older adults, providing a backdrop for culturally acceptable service development.

Why it matters

This study found that most dementia and depression in older adults in China went undetected. It identified low education, low occupation, and rural living as factors linked to undetected dementia, but it does not test any treatment or cure.
