Optimizing Cognition Via Exercise and Nutrition (OCEAN)

August 13, 2025 updated by: University of Illinois at Urbana-Champaign
Investigators propose to test the preliminary efficacy of the refined BAILAMOS™ Latin dance program plus a culturally tailored MIND diet (Mediterranean-DASH diet intervention for neurodegenerative delay) program on cognitive function among older Latinos (ages 50+) at risk of cognitive decline. This project will test whether participants randomized to the BAILAMOS™ Latin dance plus MIND diet experience better cognitive outcomes than participants randomized to the BAILAMOS™ Latin dance plus a health education program.

Detailed Description

By 2060, the prevalence of Alzheimer's disease (AD) in Latinos is projected to increase by 832%. There is an urgent need to create non-pharmacological interventions to reduce the risk of AD among Latinos. Physical activity (PA) and diet interventions (e.g. Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND)) have been shown to decrease the incidence of AD. Behavioral interventions that concomitantly target physical activity (PA) and diet have shown an improvement in cognitive function; however, these studies have not been conducted in older Latinos nor have they included culturally appropriate interventions. The need to test culturally appropriate PA and diet interventions that have the potential to reduce the loss of cognitive function in older Latinos, a group at elevated risk of health disparities, is of high public health importance. OCEAN (Optimizing Cognition via Exercise and Nutrition) is a 6-month multidomain (Latin dance plus MIND DIET) intervention delivered virtually to middle-aged and older Latinos. The investigators propose a pilot randomized controlled trial to test the preliminary efficacy of the refined BAILAMOS™ Latin dance program plus MIND (Mediterranean-DASH diet intervention for neurodegenerative delay)- a new program tailored for the protection of the brain. The impact of the combined program (intervention group (IG)) will be compared to a BAILAMOS™ plus health education (control group (CG)) on cognitive performance among middle-aged to older Latinos at risk of cognitive decline.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Montreal Cognitive Assessment (MoCA)
Time Frame: Change in scores from baseline to post-intervention 6 months
MoCA version 8.1 Blind will be used to assess global cognition. The MoCA-BLIND assesses different cognitive domains such as attention and concentration, memory, language, conceptual thinking, calculations, and orientation. It contains the same items as the original MoCA except those requiring visual abilities have been removed as this is administered over the phone. Time to administer the MoCA- BLIND is approximately 5-10 minutes. The total possible score is 22 points; a score of 19 or above is considered normal.
Change in scores from baseline to post-intervention 6 months
WMS-R: Wechsler Memory Scale-Logical Memory I & II
Time Frame: Change in score from baseline to post-intervention 6 months
Logical Memory I & II will be used to assess episodic memory. A brief story will be read to the participant who will then asked to retell it immediately (I) and after a 10- min delay filled with other activities (II). The score is the number of the 25 story units recalled immediately (I) and after the delay (II).
Change in score from baseline to post-intervention 6 months
Stroop Neuropsychological Screening Test (Trennerry et al., 1989)
Time Frame: Change in score from baseline to post-intervention 6 months
Stroop Test will be used to assess executive function. In Stroop C, participants are shown a list of colors printed in conflicting color ink and are asked to read words (names of colors). The second part of this task is Stroop CW in which participants are shown a list of colors printed in conflicting color ink and are asked to say the color of the ink the word is printed. The scores are the number of words named correctly in 30 seconds and the number of colors named correctly in 30 seconds subtracting the number of errors. respectively.
Change in score from baseline to post-intervention 6 months
Digit Span Test (Wechsler, 1987)
Time Frame: Change in score from baseline to post-intervention 6 months
Digit Span Forward & Backward will be used to assess working memory. Digit strings of increasing length will be read, and the participant is asked to repeat each string forward (Digit Span Forward) or backward (Digit Span Backward). The score is the number of correctly retrieved strings in each part.
Change in score from baseline to post-intervention 6 months
Word fluency Test (Welsh et al., 1994)
Time Frame: Change in score from baseline to post-intervention 6 months
Word Fluency will be used to assess executive function. The Word Fluency Test asks participants to name as many animals (part 1) or fruits and vegetables (part 2) as possible in 60 seconds. The score is the sum of the number of animals and the number of fruits and vegetables named.
Change in score from baseline to post-intervention 6 months
Digit Ordering Test (Cooper at al., 1991)
Time Frame: Change in score from baseline to post-intervention 6 months
Digit ordering test will be used to assess working memory. For Digit Ordering, digit strings of increasing length will be read and the participant is asked to reorder the digits and say them in ascending order. The score is the number of correctly reordered strings.
Change in score from baseline to post-intervention 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Godin-Shephard leisure-time physical activity questionnaire (GLTEQ)
Time Frame: Change in activity score from baseline to post-intervention 6 months
The GLTEQ is a 3-item questionnaire that assesses the number of times in the past week an individual participates in strenuous (eg, jogging), moderate (eg, brisk walking), and mild (eg, easy walking) exercise of more than 15 minutes in duration. Frequencies from the strenuous and moderate items are multiplied by 9 and 5 metabolic equivalents, respectively, and summed to calculate a moderate-to-vigorous activity score in accordance with the GLTEQ scoring protocol.
Change in activity score from baseline to post-intervention 6 months
MIND diet adherence
Time Frame: Change in MIND diet adherence from baseline to post-intervention 6 months
Block 2005 Food Frequency Questionnaire will be used to compute MIND diet scores. Frequency of consumption for food items was assigned a score of 0, 0.5, or 1, where scores ranged from 0 (lowest adherence) to 15 (highest adherence).
Change in MIND diet adherence from baseline to post-intervention 6 months
National Institutes of Health (NIH) Toolbox: Perceived Stress Fixed Form Age 18+ v2.0
Time Frame: Change in scores from baseline to post-intervention 6 months
NIH Tool box measure of perceived stress is a self-reported measure that assesses how unpredictable, uncontrollable, and overloaded respondents find their lives. 10 items are administered using a 5-point scale, with options ranging from "never" to "very often". Higher scores are indicative of higher perceived stress.
Change in scores from baseline to post-intervention 6 months
