HANDGRIP STRENGTH AND SOME RELATED FACTORS AMONG OLDER PATIENTS WITH OSTEOPOROSIS

Abstract

Objectives: To assess handgrip strength (HGS), lower limb strength, and some related factors among older people with osteoporosis. Subjects and Methods: A cross-sectional study was conducted on 141 older patients with osteoporosis examined and treated at National Geriatric Hospital from June to October 2022. HGS was measured using a handgrip strength dynamometer, and lower limb strength was assessed by the 5-time chair stand test. General information, characteristics of osteoporosis, and geriatric syndromes were collected. Results: Overall, 56% of participants had impaired HGS, and 24.8% had impaired lower limb strength. Older age was significantly associated with lower HGS (p<0.05). Participants with impaired HGS had a lower mean body mass index (BMI) (p<0.05). The prevalence of lumbar spondylosis and diabetes differed significantly between participants with and without impaired HGS (p<0.05). Individuals who experienced pain and lumbar spine deformity had a higher prevalence of impaired HGS (p<0.05). Cognitive decline increased the risk of HGS impairment by 5.7 times. In addition, the risk of HGS impairment was higher among participants with low physical activity (OR=3.9), sleep disturbance (OR=3.8), depression (OR=3.7), frailty syndrome (OR=3.5), risk of falls (OR=3.4), and malnutrition (OR=2.2). Conclusion: Half of the study participants had reduced HGS, and one-quarter had reduced lower limb muscle strength. Age, BMI, diabetes, lumbar spondylosis or other joint diseases, living status, and geriatric syndromes were significantly associate
