Dementia prevalence in a population at high vascular risk: the Trinidad national survey of ageing and cognition.

ABSTRACT:

Objective

To investigate the dementia prevalence in a country with high levels of cardiovascular risk factors DESIGN AND METHODS: Older people in Trinidad are recognised to have particularly high levels of cardiovascular risk factors. We carried out a survey in a nationally representative sample of people aged ≥70 years using household enumeration. Dementia status was ascertained using standardised interviews and algorithms from the 10/66 schedule and age-specific prevalence were compared with identically defined output from the 10/66 surveys of 16 536 residents in eight other low-income and middle-income countries.

Results

Of 1832 participants (77.0% response rate), dementia was present in 442 (23.4%). Prevalences were 12.0% in persons aged 70-74 years, 23.5% at 75-79, 25.8
