Effectiveness of NeoMayor in Improving Cardiovascular Health (NEOMAYOR)

June 2, 2026 updated by: University of Chile

Effectiveness of NeoMayor in Improving Cardiovascular Health Status in Chilean Adults

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.

Study Overview

Detailed Description

Population aging in low- and middle-income countries has led to an increasing burden of non-communicable diseases, particularly cardiovascular disease and dementia. A substantial proportion of cardiovascular and dementia risk factors are modifiable, making lifestyle-based preventive interventions a public health priority.

Multidomain interventions targeting physical activity, diet, sleep, and psychosocial factors have demonstrated effectiveness in reducing cardiovascular risk and supporting cognitive health. However, implementation barriers such as limited access, low adherence, and healthcare inequities reduce their impact in real-world settings.

Mobile health interventions offer a scalable alternative, particularly in settings with increasing smartphone adoption among older adults. NeoMayor was developed using a user-centered design approach and demonstrated feasibility and potential effectiveness in a pilot study conducted in Chile.

This study will evaluate the effectiveness of NeoMayor in improving cardiovascular health using the Life's Essential 8 Cardiovascular Health Index, a composite measure developed by the American Heart Association that includes modifiable behavioral and biological cardiovascular risk factors. The trial will also explore cognitive and mental health outcomes as well as pshysical performance associated with lifestyle improvement.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Life's Essential 8 Cardiovascular Health Index (CVHI)
Time Frame: Baseline and 4 months

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.
