Background In clinic, a subjective visual estimation of a patient’s general health often guides interventions, yet little is known of how this assessment relates to objectively measured frailty. Aims To characterize the relationship between these two assessments and explore the implication of discordance. Methods The study was performed in the OPRA cohort of 75-year old community-dwelling women ( n  = 1044). Visual perception of health (VPH) was estimated within 15 s from first sight and stratified into tertiles (poor/intermediate/good health). Frailty was measured using a frailty index (FI) (scored 0.0–1.0) and stratified into tertiles: ‘ frail’  (≥ 0.22), ‘ pre-frail’  (0.13–0-21) and ‘ non-frail’  (≤ 0.12). Association between VPH and FI and with 10-year mortality was evaluated using Kaplan Meier curves and Cox proportional hazard models. Results VPH and FI correlated, but was strongest in those perceived to be in poor health ( r  s  = 0.424,  p  &lt; 0.001). Approximately half of these women were also objectively frail (53.7%). Similarly, 50.7% perceived to be in good health were also objectively non-frail. However, for one in ten, perceived health was discordant with measured frailty. Subjective and objective measures were associated with mortality, but VPH lacked discrimination in healthier looking women ( p  = 0.372) compared to FI ( p  = 0.002). Discussion Detecting pre-frailty is important to prevent or slow the transition into a frail state. The frailest can be identified with a visual estimation, but only objective frailty assessments can reliably identity pre-frailty. Conclusions A visual estimation of health provides valuable complementary information on health, whereas objective assessment of frailty has a broader applicability for health in aging.
