Objective: Handgrip strength (HGS) has several clinical implications. The study aimed to determine indicators of low HGS and its association with sleep quality among community-dwelling geriatric persons. Materials and Methods: A cross-sectional study included 120 older adults in the community. Charlson Comorbidity Index (CCI) assessed multimorbidity. Anthropometrics included body mass index (BMI) and waist-hip ratio (WHR) measurements. The Pittsburgh Sleep Quality Index (PSQI) and Jamar dynamometer determined sleep quality and HGS in kilograms (kg), respectively. Low HGS was determined according to adjusted cut-offs based on participants’ BMI and sex. PSQI score >5 defined as poor sleep quality. The short physical performance battery (SPPB), activities of daily living (IADLs), and instrumental IADLs were performed. The mini-mental state examination, the patient health questionnaire-9 (PHQ-9), and the general anxiety disorder questionnaire-7 (GAD-7) were conducted. Statistical analyses were executed. Results: The mean age and HGS were 67.26 years and 27.06 kilograms, respectively. Median PSQI score was 7. Seventy-six (63.3%) patients had low HGS while 97 (80.0%) had poor sleep quality. Indicators of low HGS were BMI >27.3 kg/m2, CCI >2, PHQ-9 >3, and total balance test score ≤2. PSQI score was significantly related to BMI, depression, and low HGS with P 0.007, 0.00, and 0.006, respectively. PSQI scores inversely correlated with IADL (r: -0.197), HGS (r: -0.254), SPPB (r: -0.338) and positively correlated with BMI (r: 0.336), WHR (r 0.189), PHQ-9 (r: 0.457), and GAD-7 (r 0.438). PSQI score >6 identified low HGS with sensitivity 63.16% and specificity 68.18%. Conclusion: The study identified low HGS indicators. HGS was inversely correlated with PSQI score.
