Accelerometry provides researchers with a powerful tool with which to measure physical activity in population-based studies, yet this technology has been underutilized in cross-cultural studies of older adults. This study of 200 older adults in urban India combines seven days of accelerometry with anthropometric, sociodemographic, and health data in order to: 1) examine the impact of different monitoring durations; 2) evaluate links between activity and anthropometric and sociodemographic variables; and 3) consider links between activity and measures of health and physical fitness. Results reveal overall low activity levels, with significantly lower activity energy expenditure (AEE) among females (P<0.05). No significant differences were documented in activity level by monitoring duration. Age was negatively correlated with AEE in males (P<0.01) and females (P<0.001). Women who were more socially integrated had greater AEE (P<0.01). Finally, activity measures were associated with several health and physical function variables including grip strength and timed walk.
