Sample details

The 10/66 Dementia Research Group Population-Based Cohort Study investigates the lives of older people in 8 study sites in low and middle-income countries with the aim of providing evidence for policy development and reform. Beginning in 2003, 10/66 Cuba recruited adults at least 65 years old from Matanzas and the larger Havana Province in Cuba. Over 2,900 adults of varying socioeconomic, educational, marital, and occupational backgrounds participated in the baseline data collection sweep between 2003 and 2005. Participants were followed up between 2007 and 2011 and again between 2016 and 2018.
