Design

Study design
Cohort
Follow Up
Participants were followed every 12 to 15 months, for a maximum of 6 follow-ups, via home visits that included clinical and cognitive assessments. Brief semi annual phone visits were also conducted.
Supplementary Information

The main study was a cohort study design, however, a cross-sectional prevalence study design was used at baseline.

A number of substudies were done, including MRIs in demented, impact of dementia in caregiver health, and intergenerational studies.

Supplementary Information

The first stage of the sampling involved identifying 1998 Census tracts in five contiguous counties and characterizing them by the percentage of eligible residents (aged 60 and Latino).

Because the recruitment occurred 8 years after the 1998 Census, a phone and address list was purchased of people aged 60 and over with Latino surnames in the target area. This list was used to identify census tract areas where there might have been a change in the eligible population since 1998 and to contact individuals in the selected census tracts. Participants were contacted in three stages: by mail, by phone, and, finally, by door-to-door neighborhood enumeration. Up to 10 attempts to contact the participant by telephone were allowed and up to five attempts at the household. Participants who contacted the study themselves were screened for eligibility, residence in a target census tract, and presence on the sampling list.
