Rationale: Obesity is considered a risk factor for falls. However, the results are conflicting, maybe due to different obesity measurements. This study aimed to examine the association of obesity based on Body Fat Percentage (%BF) or Body Mass Index (BMI) with the incidence of falls in one year.
Methods: Subjects were 479 outpatients who had visited the frailty clinic in the NCGG. In the clinic, we evaluated %BF, physical performances, hand grip strength, activity, and background factors such as mood, living alone, history of falls, etc. The %BF was measured using the bioimpedance method. The BMI (kg/m2) was classified into three groups: Underweight (<18.5), Normal (18.5-24.9), and Obesity (25≤). Obesity based on the %BF was defined as %BF ≥20% and ≥30% for men and women, respectively. The subjects were asked whether they had fallen over one year after the baseline visit. The relationship between %BF or BMI and falls was analyzed using logistic regression.
Results: Among 479 subjects, we could follow 282 patients in one year, excluding persons assessed for orthopedic surgery. The mean age was 76.7 years (53-96), with a 34.0% male distribution. Eighty-four persons experienced one or more falls (29.8%). The odds ratios (95% CI) of the %BF-defined obesity with the incidence of falls over one year, adjusted for age, sex, history of falls, depressive mood, low activity, balance disturbance, and the number of comorbidities, were 2.421 (1.251-4.687), with a statistically significant. However, the BMI-defined obesity did not reach a statistical significance.
Conclusion: The %BF-defined obesity was significantly associated with falls in one year.
