Abstract Background Physical activity (PA) is key for the well-being of the elderly. Despite its proven efficacy, many older adults remain sedentary. Digital health interventions offer promising results. The study aimed to appraise scientific literature evidence regarding digital interventions to improve physical activity levels among community-dwelling adults aged 60 years or older. Methods A systematic review and semiquantitative analysis were performed. Digital interventions were included if using eHealth/mHealth tools, app-based technologies and text messaging. An intervention control was required. Main outcomes consisted in physical activity levels and related measures. A semiquantitative approach was chosen for evidence synthesis, using a harvest plot to visually facilitate the weighing of results with sample size and quality assessment. Results A total of 10 studies (13 publications) were included, from which five main intervention types were identified (2 studies per each intervention type). A semiquantitative evidence synthesis via a harvest plot was performed, to base the studies evaluation on the simultaneous consideration of sample size, study quality by type and effectiveness of intervention. Interventions adopting dynamically-adjusted exercise plans via wearables and app-based digital peer-support resulted the most successful, whereas PA digital coaching interventions resulted the least recommendable for adoption. Motivating interventions through digital platforms and digital diaries showed inconclusive results. Conclusions Personalized interventions using dynamically-adjusted wearable-based technology and app-based digital peer-support ones resulted as the most promising. Their ability to provide real-time, personalized feedback and foster social support is key for health promotion. It is crucial to leverage these promising tools for enhancing population health, integrating them into comprehensive, equitable, sustainable and engaging public health interventions. Key messages • Interventions using personalized and dynamically-adjusted plans result as the most effective to increase physical activity amond the elderly. • It is key to integrate effective digital health tools into comprehensive, equitable, sustainable and engaging public health interventions to enhance population health.
