Efficacy of mHealth-Based Workplace Health Promotion Strategy in Improving Cardiorespiratory Fitness in a Healthcare Setting: A Randomized Controlled Study.

Abstract

This study aimed to test the efficacy of a mHealth-based workplace health promotion strategy in improving cardiorespiratory fitness in a healthcare setting. Seventy-seven female nurses (age, 30-45 years) meeting the inclusion criteria underwent baseline assessment and received either a 12-week mHealth or awareness intervention based on their workplace. Changes in peak oxygen consumption (VO 2 ), fasting blood sugar, and physical activity were compared within and between the groups at the end of the intervention. Thirty-seven and 33 participants in the mHealth and awareness arms, respectively, completed the 12-week intervention. Peak VO 2 (1.6 mL/kg/min, 7%), physical activity, and step counts improved significantly in the mHealth arm. However, between-group differences were not significant. mHealth interventions offer unique opportunities to improve physical activity and cardiorespiratory fitness among health professionals in their workplace.
