The Harmonized Cognitive Assessment Protocol (HCAP) is a major innovation that provides, for the first time, harmonized data cross-national comparisons of later-life cognitive functions are sensitive to linguistic, cultural, and educational differences across countries. However, function does not lend itself direct comparison diverse populations without careful consideration best practices such comparisons. This perspective discusses theoretical methodological considerations offers set recommended conducting risk factor associations using HCAP data. Because existing planned studies provide cognition representing an estimated 75% global population ≥65 years age, these will support high-quality comparative analyses aging around world. principles described in this applicable any researcher aiming integrate or compare on outcomes their protective factors populations.

Abstract Background Established evidences have demonstrated that hypertension was associated with the cognitive impairment. But associations between duration of exposure and performance are still inconclusive. Objectives The objective this study to assess association diagnosis in older adults by National Health Nutrition Examination Survey (2011–2014). Methods To evaluate relationship performance, we conducted logistic regression analysis. Furthermore, also performed Restricted cubic spline (RCS) analysis nonlinear performance. Results Initially, total 19,931 participants were included study, 2928 individuals enrolled. With increase duration, more risk impairment observed Digit Symbol Substitution test (DSST) (OR = 1.012, 1.006–1.019), a similar trend Animal Fluency (AFT) (OR=1.009,1.003–1.016). RCS results showed pattern linear DDST (P for non–linearity 0.758). Meanwhile, subgroups midlife hypertension, revealed DSST non–linearity=0.391) CERAD non–linearity= 0.849) among diagnose < 55 years populations. Conclusion Collectively, our finding indicates longer worsens cognition especially middle-aged hypertension.
