De Pie y a Movernos-undersøgelse: Fremme af fysisk aktivitet hos ældre latinamerikanske/latino(a) voksne
In this randomized controlled trial, study staff will randomize 130 Hispanic/Latino adults without dementia and over age 55 from Southern California and from Kaiser Permanente Washington (State) to either the culturally adapted De Pie physical activity intervention or an active comparison program focusing on general brain health topics. The purpose of this study is to determine if 12 weeks of the culturally adapted and fully remote De Pie y a Movernos intervention improves self-efficacy, habit strength, social support, and enjoyment for physical activity (PA), thus promoting adherence to moderate-intensity physical activity (MIPA) guidelines (150 minutes/week).

Detaljeret beskrivelse
Building on the cultural adaptation of our preliminary R61 De Pie pilot study, study staff will randomize 130 Hispanic/Latino adults without dementia and over age 55 from Southern California and from Kaiser Permanente Washington to either the culturally adapted De Pie physical activity intervention or an active comparison program, Healthy Actions and Lifestyles to Avoid Dementia (HALT-AD), focusing on general brain health topics. The investigators will determine if De Pie improves physical activity (Aim 1) and psychosocial mediators (self-efficacy, habit strength, social support, and enjoyment for physical activity, [PA]), thus promoting adherence to moderate-intensity physical activity (MIPA) guidelines (150 minutes/week; Aim 2). The intervention period lasts 12 weeks.
The investigators target middle-aged and older Hispanic/Latino adults that are under-studied and have a higher risk of Alzheimer's disease and related dementias (ADRD), compared to non-Hispanic White older adults. Study staff employ a community engaged and collaborative approach to culturally adaptive the intervention framework and a staircase intervention approach designed to build self-efficacy, PA habit strength, social support, and PA enjoyment. Results will inform culturally adapted, theory-based approaches to prevent ADRD in the Hispanic/Latino community.

Intervention / Behandling |
|---|---|
|
Eksperimentel: De Pie Intervention
The De Pie intervention program receives a sedentary behavior reduction and physical activity promotion intervention centered on two steps: Step 1) reduce sitting time and move more throughout the day; Step 2) if cleared by a safety assessment and blood pressure check, participants can work towards adding structured bouts of exercise into their day. |
Participants are guided by a health coach trained in motivational interviewing through 6 biweekly phone sessions. Each session involves reviewing goals and problem-solving barriers from the prior 2 weeks experience; covering a topic related to Step 1 goals (or Step 2 goals if they pass the safety assessment) such as how to enjoy movement, social support, and using your surroundings; and setting goals and an action plan for the following two weeks. |
|
Aktiv komparator: HALT-AD Active Comparison Group
Those randomized to HALT-AD (Healthy Actions and Lifestyles to Avoid Dementia) will receive one phone call to introduce them to preventing cognitive decline through various lifestyle behaviors (e.g. stress reduction, healthy diet, healthy sleep) other than physical activity. They will be encouraged by the Health Coach upon randomization to complete one module approximately every week (there are 10 modules in total). |
Those in the active comparison program will receive no additional health coaching sessions. They will work through the HALT-AD content at their own pace, setting goals in the online platform as they go. |
