Is self-reported hypertension accurate for identifying patients with hypertension in epidemiological studies?
Self-reported hypertension misses a substantial proportion of patients and can introduce significant bias in epidemiological research.
Less than half of patients with HTN would not be identified by self-reporting in epidemiological studies. Self-reported HTN has important limitations and may represent an important source of bias in research depending on regional, socioeconomic, and cultural differences.
Gonçalves et al. (Tue,) studied this question.
