Factors Related with Hand Grip Strength in Korean Elderly

Background: Hand grip strength is important to identify old people with functional limitation. The objective of this study was to investigate the factors related with Reduction of Hand grip strength in Korean elderly. Methods: Korean community-dwelling elderly (n=3,598, male/female 1,577/2,021) at the first wave (2006) of KLoSA (Korean Longitudinal Study on Aging) were used for analysis. Hand grip strength was assessed with Dynamometer for 2times each arm and we calculated hand grip index. Hand grip strength, Socioeconomic status, Health related status was assessed through personal interviews by a trained interviewer with Computer Assisted Personal Interviewing (CAPI). Results: 1,684 subjects (46.8%) were classified as Low hand grip strength group (＜26 kg for male, ＜18 kg for female). Age, sex, MMSE score, education, employment, living with spouse, social activity, depression scale (Center for epidemiologic studies depression scale, CESD-10), function (Activity of daily living, ADL), smoking, drinking, BMI (Body mass index), hypertension and diabetes was significantly related with low hand grip strength. Low hand grip strength ratio for age 70∼74 and ≥75 were 1.68 (1.40∼2.02) and 2.89 (2.39∼3.50) compare to younger age group, female was 2.04 (1.73∼2.40), cognitive impairment was 1.84 (1.57∼2.16), no exercise group was 1.34 (1.13∼1.58). Among health-related factors, alcohol consumption and diabetes were significantly higher in low grip strength group. Among physical/psychological factors, cognitive impairment (MMSE≤23), function (ADL), depression scale (CESD-10), obesity were significantly different after multivariates adjustment. Conclusion: Age, sex, education, employment, alcohol consumption, diabetes, cognitive impairment, depression scale (CESD-10), function (ADL), exercise, obesity were significantly related with cognitive decline in Korean elderly.
