34 Gender Difference in the Association between Handgrip Strength and Cognitive Performance of Older Adults in Rural Malaysia

Abstract Introduction Handgrip strength is an easy and safe measurement to evaluate the physical functioning of older adults. Lower hand grip strength is associated with cognitive decline, and can be used as an effective method for early detection of cognitive impairment. Objective This study aimed to evaluate the gender differences in association between hand grip strength and cognitive performance among older adults in rural Malaysia Methods This was a cross-sectional study done among 200 community dwelling older adults (100 men and 100 women) aged ≥ 50 years. The study was embedded in the ongoing longitudinal study of South East Asia Community Observatory (SEACO) in Segamat district of Johor, Malaysia. Data was collected by trained data collectors during home visits. Cognitive performance was assessed using Mini Mental State Examination (MMSE). Hand grip strength was measured using digital grip dynamometer. Results The mean age of study participants was 61.5 years (SD= 8.4). Women had lower mean hand grip strength (19.8, SD=5.6) compared to men (33.4, SD= 8.2). The mean MMSE score for women and men were 23 (SD= 4.5) and 25.1(SD=3) respectively. Cognitive impairment was detected in 26% of men and 21% of women. Hand grip strength showed positive association with MMSE score, among women (ß coefficient= 0.302, p
