Key result
Higher systolic blood pressure and lower diastolic blood pressure were each independently associated with worse cognitive function among older adults in India.
Why the study?
The relationship between blood pressure and cognitive function among older adults in India needed investigation.
Cross-Sectional (n=3,690)
Yes
In older adults in India, higher systolic and lower diastolic blood pressures are independently associated with worse cognitive function, suggesting blood pressure management may impact cognitive health.
May prompt BP evaluation in cognitive assessments of older Indians; extends associations but leaves causality and targets open.
Objective We aimed to investigate the relationship between blood pressure and cognitive function among older adults in India. Methods In this study, we analyzed cross-sectional data of systolic and diastolic blood pressure (SBP and DBP, respectively) and cognitive testing from 3690 adults aged 60 years and older participating in the Longitudinal Aging Study in India—Diagnostic Assessment of Dementia from 14 states in India. Results After controlling for key sociodemographic, health, and geographic factors, higher SBP and lower DBP were each independently associated with worse cognitive function. Older age, female sex, lower education level, being widowed, residing in a rural area, being a member of a Scheduled Caste or Scheduled Tribe, having a low level of economic consumption, being underweight, and a history of stroke were all independently associated with worse cognitive function scores. Conclusions Both SBP and DBP were independently associated with cognitive function among older adults in India in diverging directions. Clinical interventions targeting high SBP and low DBP may benefit both cognitive health and cardiovascular health.

Farron et al. (2022) conducted a cross-sectional in Cognitive function (n=3,690). Systolic and diastolic blood pressure was evaluated on Cognitive function. Higher systolic blood pressure and lower diastolic blood pressure were each independently associated with worse cognitive function among older adults in India.
