Adherence
Individuals significantly underestimate their cardiovascular risk and their level of physical activity, demonstrating a disconnect between perceived and actual metrics.
Do not rely on your gut feeling to judge your health risk or activity level. You are likely underestimating your risk and overestimating your activity. Use objective tools like smartphone sensors or medical checkups to get a true picture of your cardiovascular health.
ModerateRefutesMEDIUM confidence
Individuals’ perception of their activity and risk bore little relation to sensor-estimated activity or calculated cardiovascular risk.
Why this rating
Observational study with self-reported data; correlation is low but statistically significant.
