The Association Between Social Engagement, Mild Cognitive Impairment, and Falls Among Older Primary Care Patients

To examine associations between mild cognitive impairment (MCI) and falls among primary care patients, and to investigate whether social engagement (SE) modifies these associations. Cross sectional analysis using baseline data from an observational cohort study. Primary care. Community-dwelling older adults (N=430) at risk of mobility decline with a mean age of 76.6 years (range 65-96y). The number of falls in the past year was reported at the baseline interview. MCI was identified using a cutoff of 1.5 SD below the age-adjusted mean on at least 2 of the standardized cognitive performance tests. SE (eg, keeping in touch with friends and family, volunteering, participating social activities…) was assessed with the Late Life Function and Disability Instrument, and required a score above the median value 49.5 out of 100. MCI was present among 42% of participants and 42% reported at least 1 fall in the preceding year. Using generalized estimating equations, MCI was associated with a 77% greater rate of falls (P
