Background:Aging involves parallel deterioration across multiple physiological systems. Although cardiovascular, respiratory, cognitive, and psychological changes are well documented individually, their interdependence and combined impact on functional decline remain insufficiently explored, particularly in low- and middle-income country settings such as India.
Objectives:To examine the associations and potential mechanistic links among cardiovascular, respiratory, cognitive, and psychological functions in a community-dwelling urban elderly population in India.
Methods: A community-based cross-sectional study was conducted among 180 individuals aged 60 years residing in a Tier-2 city. Cardiovascular assessment included blood pressure and heart rate variability (HRV); respiratory function was evaluated using spirometry; cognitive performance was measured using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA); and psychological distress was assessed using the GHQ-12 scale. Correlation analyses, hierarchical multiple linear regression, and k-means cluster analysis were employed to explore inter system relationships.
