Purpose: Dizziness and balance impairment are major risk factors for falls in older adults. While grip strength decline and depressive symptoms are independently associated with balance problems, few studies have examined their combined effects in community-dwelling adults aged 65 years and older. Methods: This cross-sectional study analyzed data from the 2019, 2022, and 2023 Korean National Health and Nutrition Examination Survey (KNHANES), comprising 3,407 participants aged 65 years or older. Grip strength was measured using a digital dynamometer, and low grip strength was defined according to the 2019 Asian Working Group for Sarcopenia (AWGS) criteria (men <28 kg, women <18 kg). Depressive symptoms were assessed by asking whether participants had experienced persistent feelings of sadness or hopelessness for two consecutive weeks. Participants were classified into four groups: (1) normal grip strength with no depressive symptoms (reference group), (2) low grip strength only, (3) depressive symptoms only, and (4) both conditions combined. Complex sample logistic regression analyses were conducted using SPSS 29.0, adjusting for sex, age, education, income, smoking, alcohol use, hypertension, diabetes, and survey year. Results: The weighted prevalence of dizziness or balance impairment was 38.2%. In the fully adjusted model, adjusted odds ratios (AOR) relative to the reference group were as follows: low grip strength only, 1.23 (95% CI: 0.94–1.61, p = 0.132); depressive symptoms only, 2.18 (95% CI: 1.59–3.01, p < 0.001); and combined, 2.21 (95% CI: 1.16–4.20, p = 0.016). No significant interaction effect was observed (p = 0.462). Conclusion: Depressive symptoms showed a stronger association with dizziness and balance impairment than grip strength decline, with no synergistic effect between the two factors. These findings suggest that screening for depressive symptoms should be prioritized alongside physical assessments in fall prevention programs for older adults.
