Altered Body Composition in Dizziness and Vestibular Dysfunction: Insights From the Korean National Health and Nutrition Examination Survey.

Sarcopenia was associated with a higher risk of dizziness with vestibular dysfunction compared to dizziness without vestibular dysfunction.

• Odds ratio of 1.65 (95% CI, 1.09–2.49; P = 0.017) for dizziness with VD versus dizziness without VD
• Finding derived from multivariate regression analysis
• Cross-sectional study design with 9,682 participants aged over 40
• Participants were classified using a dizziness questionnaire and modified Romberg test

Sarcopenia was associated with a higher risk of dizziness with vestibular dysfunction compared to the control group.

• Odds ratio of 1.92 (95% CI, 1.28–2.88; P = 0.002) for dizziness with VD versus controls
• Finding derived from multivariate regression analysis
• Controls were participants without dizziness or vestibular dysfunction based on questionnaire and modified Romberg test results

Sarcopenia was significantly associated with dizziness only in the group with vestibular dysfunction, not in those without it.

• The association between sarcopenia and dizziness was specific to the vestibular dysfunction subgroup
• No significant association was found between sarcopenia and dizziness in the group without vestibular dysfunction
• Three groups compared: dizziness associated with VD, dizziness without VD, and controls

Proportions of bone mineral and fat were comparable among the three participant groups.

• Body composition analysis focused on muscles, bones, and fats
• No significant differences in bone mineral content or fat proportions were found across the dizziness with VD, dizziness without VD, and control groups
• Suggests the body composition alteration in vestibular dysfunction is specific to muscle mass rather than bone or fat

The study population was classified into three groups based on dizziness questionnaire results and the modified Romberg test.

• Total of 9,682 participants aged over 40 were included
• Cross-sectional study using data from the Korean National Health and Nutrition Examination Survey
• Groups classified as: dizziness associated with vestibular dysfunction, dizziness without vestibular dysfunction, and controls
• The modified Romberg test was used to assess vestibular dysfunction
