Observable, but Not Unobservable Health Numbers are Associated With Self-Reported Health: NHANES 2017-2020

Area of Science:

• Public Health
• Health Outcomes Research
• Biostatistics

Background:

• Self-reported health is a key indicator of an individual's well-being.
• Understanding the relationship between perceived health and objective health measures is crucial for effective healthcare.
• Discrepancies between self-perception and clinical measures can impact patient care and health management.

Purpose of the Study:

• To investigate how self-reported health status relates to objectively measured health indicators.
• To determine if perceived health accurately reflects physiological health markers.
• To explore potential factors influencing the alignment between subjective and objective health assessments.

Main Methods:

• Utilized data from the National Health and Nutrition Examination Survey (NHANES) 2017-2020 pre-pandemic dataset.
• Employed analyses of covariance with self-reported health as the independent variable.
• Dependent variables included blood pressure, waist-to-hip ratio, fasting glucose, and total cholesterol, with family income as a covariate.

Main Results:

• Significant associations were found between self-reported health and blood pressure, waist-to-hip ratio, and fasting glucose levels.
• Individuals reporting 'excellent' or 'very good' health demonstrated better objective health markers compared to those reporting 'fair' or 'poor' health.
• No statistically significant relationship was observed between self-reported health and total cholesterol levels.

Conclusions:

• Objective health metrics measurable outside clinical settings may align more closely with an individual's perceived health.
• Healthcare providers should encourage patients to recognize their health status more accurately.
• Integrating data from wearable technologies could enhance health perception and improve patient care strategies.
