Identification and Intervention for Dementia in Elderly Africans Study (IDEA)
The IDEA study was conducted in the rural Hai district of northern Tanzania. In 2014, community-dwelling people aged 65 years and over living in six villages were invited to take part in a cognitive screening program. All participants from four of the six villages were followed-up at two years and cognitive function re-tested. There were 186 females (56.9%) and the mean age at follow-up was 76.2 years. Two-hundred and ninety-eight (91.1%) reported being farmers and 189 (57.8%) reported still working. Eighty-one (24.8%) participants said they were illiterate and 82 (25.1%) had completed seven years of primary education.
