C.E.R.E.B.R.O.: A home-based physical activity study for older Latino adults

The growing Latino population is 1.5 times more likely to develop Alzheimer's Disease (AD) and Related Dementias (ADRD) than non-Latino Whites. Interventions that can reduce the risk of ADRD are needed. Older Latinos face many barriers to the incorporation of physical activity (PA) into their daily lives given a lack social support, caregiving responsibilities, and lacking resources to maintain PA. Walking and dancing are the two most frequently reported forms of PA among older Latinos, and indoor PA programs conducted in a community location or at home can overcome barriers to participation.

C.E.R.E.B.R.O. (Cognitive Enhancement and Risk-reduction through Exercise for Brain-Related Outcomes; meaning "brain" in English) is testing two remote intervention programs, the BAILAMOS™ dance program and ¡En Forma y Fuerte! (Fit & Strong!), a PA/behavior change program. Participants are randomly assigned to either study condition. The BAILAMOS™ dance program is a 6-month long dance program, in which participants learn different Latin dances including Merengue, Cha Cha Cha, Bachata, Salsa, Cumbia, and Kizomba. Trained CEREBRO staff also lead monthly discussions. Persons randomized to the 3-month long ¡En Forma y Fuerte! program participate in flexibility and aerobic exercise, strength training, and health education. All classes are held live via Zoom. Trained study staff assist participants with technology-related issues. Data are collected through remote testing at baseline, 12 weeks, and 24 weeks after the start of the interventions. Outcomes include PA, cognition, quality of life, social connectedness, and cost-effectiveness.

CEREBRO has the potential to provide evidence regarding the advantages of providing remote intervention programs to reduce PA barriers in the older Latino community.
