Digital connectedness, including internet and smartphone use, is linked to younger age and better cardiovascular health. However, this digital divide may limit the generalizability of studies focusing on connected populations.

Area of Science:

  • Cardiovascular epidemiology
  • Digital health technologies
  • Population health assessment

Background:

  • eHealth and mobile technology offer new ways to assess and manage large populations outside clinical settings.
  • Digital connectedness is increasingly important in public health research and interventions.

Purpose of the Study:

  • To examine the relationship between digital connectedness (internet, cell phone, smartphone usage) and demographic/cardiovascular disease risk factors in the Framingham Heart Study.
  • To assess the prevalence of digital technology use among study participants.

Main Methods:

  • A digital connectedness survey was administered to 8096 participants in the Framingham Heart Study (2014-2015).
  • Data collected included internet, email, cell phone, and smartphone usage, alongside demographic and cardiovascular disease risk factors.

  • Statistical analyses adjusted for age and sex.

    • Main Results:

    • 80.3% of participants completed the survey; 87.4% reported regular internet use, with users being younger and having more favorable cardiovascular risk profiles.
    • 92.1% used cell phones, and 67.8% of those had smartphones. Smartphone users were younger, more educated, employed, and less likely to have hypertension.
    • Internet and smartphone users were significantly younger and exhibited better cardiovascular health indicators compared to non-users.

    Conclusions:

    • Digital connectedness significantly varies by age, with younger, better-educated individuals showing higher usage.
    • Favorable cardiovascular disease risk factor profiles are associated with higher digital connectedness.
    • The limited smartphone penetration (less than two-thirds of users) and age-related differences highlight potential limitations in the generalizability of studies focusing on digitally connected populations.
