NCT07633392

Brief Summary

This study aims to evaluate the effectiveness of NeoMayor, a mobile health (mHealth) intervention designed to improve cardiovascular health among older adults at elevated cardiovascular risk in Chile. NeoMayor is a smartphone-based application that provides personalized guidance on physical activity, diet, sleep, and mental well-being through a multidomain lifestyle approach. This multicenter randomized controlled trial will enroll community-dwelling older adults aged 55 to 75 years recruited from primary healthcare centers in urban and rural settings. Participants will be randomized in a 2:1 ratio to either the NeoMayor intervention or a control group receiving standard health information and usual care. The intervention duration will be four months. The primary objective is to determine whether the NeoMayor intervention improves cardiovascular health as measured by the Life's Essential 8 Cardiovascular Health Index. Secondary objectives include evaluating changes in cognitive performance, depressive symptoms, anxiety symptoms, quality of life and physical performance outcomes. The study will also assess feasibility and adherence to digital intervention.

Outcome Measures

Primary Outcomes (1)

  • Change in Life's Essential 8 Cardiovascular Health Index (CVHI)

    The primary outcome is the change in the Life's Essential 8 Cardiovascular Health Index (CVHI) from baseline to 4 months. The CVHI is a composite cardiovascular health score ranging from 0 to 100, with higher scores indicating better cardiovascular health status. The index is based on the eight cardiovascular health components defined by the American Heart Association Life's Essential 8 framework, including:Smoking status,Physical activity,Diet quality,Sleep duration,Body mass index (BMI),Blood pressure,LDL cholesterol,Fasting glucose. Each component is standardized according to published scoring algorithms and combined to generate the overall cardiovascular health score. The primary analysis will evaluate the between-group difference in change in CVHI over time.

Study Arms (2)

NeoMayor app

EXPERIMENTAL

Participants will receive access to the NeoMayor mobile health application designed to promote healthy lifestyle behaviors through structured behavioral challenges targeting physical activity, diet, sleep, and mental well-being during 4 months. Participants in this arm will additionally be randomized to receive the intervention with or without wearable device suppor

Interventions

NeoMayor AppBEHAVIORAL

NeoMayor is a smartphone-based multidomain lifestyle intervention designed for older adults. The application delivers structured behavioral challenges and personalized recommendations targeting physical activity, healthy diet, sleep quality, and emotional well-being. Participants receive onboarding training and ongoing app-based feedback throughout the 4-month intervention period.

Also known as: mhealth, mobile software
NeoMayor app

Participants randomized to wearable support will receive a commercially available wearable activity tracker synchronized with the NeoMayor application to support self-monitoring of physical activity and health behaviors.
