[Validity of Self-reported Hypertension in Chinese Elderly Populations]
Objective:
To determine the validity of self-reported hypertension and its associated factors in Chinese elderly populations.
Methods:
Self-reported data of 13 610 elderly participants of the China Health and Retirement Longitudinal Study were compared with their actual blood pressure measurements. The sensitivity and specificity of self-reported hypertension were calculated corrected for current medication use. Multivariate logistic regression analysis was performed to identify individual characteristics that independently predicted the accuracy of self-reports.
Results:
Overall, self-reported hypertension had low sensitivity (56. 3%) and high specificity (96.9%). Agreement between self-reported data and medical records was moderate (Kappa= 0. 57). The multivariate analysis identified age, sex, education, financial situation, health service utilization, history of diabetes and types of medical insurance as significant factors that determined the validity of self-reported data.
Conclusion:
Self-reporting leads to underestimation of the prevalence of hypertension. The accuracy of self-reporting differs among subpopulations.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
