Effectiveness of NeoMayor in Improving Cardiovascular Health in Chilean Older Adults (NEOMAYOR)

5 agosto 2026 aggiornato da: University of Chile

A Hybrid Type 1 Effectiveness-Implementation Randomized Controlled Trial of NeoMayor, a Mobile Health Intervention to Improve Cardiovascular Health in Chilean Older 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.

Descrizione dettagliata

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 of 2 months conducted in Chile. That pilot did not assess sustained use beyond the initial period, so no prior data exist on how engagement or adherence evolve over a four-month intervention.

This trial follows a Hybrid Type 1 design, the primary aim is confirmatory and evaluates clinical effectiveness on cardiovascular health index; the implementation aim is exploratory and evaluates strategies to support sustained engagement. This distinction is reflected in the statistical analysis plan, where only the primary effectiveness outcome is powered for confirmatory testing.

The implementation aim is guided by the RE-AIM framework, focusing on reach, adoption, fidelity, and maintenance. Within the NeoMayor arm, participants are randomized to receive the app with or without a human health coach, and with or without a wearable device. These two implementation support strategies are evaluated through their main effects on engagement, adherence, retention, and maintenance of app use, using the full intervention arm sample. The coach x wearable interaction, and any association between implementation outcomes and clinical outcomes, will be analyzed descriptively and reported as exploratory, given the sample size was not calculated for these comparisons.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Nessun intervento: Control Group
Participants will receive standard health information and continue with their usual healthcare provided by the public health system
Sperimentale: NeoMayor app
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 four months. Within this arm, participants are further randomized to receive the app with or without human health coach support, and with or without wearable device support (2x2 factorial).
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.

  • mHealth
  • mobile software
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.
Participants randomized to coach support will receive monthly contact from a geriatrician to support onboarding, troubleshoot app use, and encourage continued engagement with the app content and challenges. This is an implementation support strategy, not an independent clinical intervention.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Life's Essential 8 Cardiovascular Health Index (CVHI)
Lasso di tempo: Baseline and 4 months
The primary outcome is the change in the American Heart Association Life's Essential 8 Cardiovascular Health Index (CVHI) from baseline to 4 months. The CVHI is a composite score ranging from 0 to 100, with higher scores indicating better outcome. The score is calculated as the unweighted average of eight cardiovascular health components: smoking status, physical activity, diet quality, sleep duration, body mass index, blood pressure, LDL cholesterol, and fasting glucose. Each component is scored from 0 to 100 according to the American Heart Association scoring algorithm, with higher scores indicating better cardiovascular health.
