Abstract

BACKGROUND: Dynapenic abdominal obesity (D/AO) has been associated with negative outcomes in older people, including trait of falls. AIMS: To assess the association between D/AO and the incidence of falls over 18 months in older community-dwelling women.

METHODS: A total of 201 older women (67.97 ± 6.02 years; 27.70 kg/m2) underwent waist circumference measurement, and had handgrip strength assessed using a hydraulic dynamometer. Dynapenia was classified using the lower tertile of handgrip strength, while abdominal obesity was considered as a waist circumference > 88 cm. D/AO was the combination of both aforementioned criteria. Volunteers were classified into four groups: normal, abdominal obesity, dynapenic, and D/AO. Participants were then tracked by phone calls for ascertainment of falls during a follow-up period of 18 months. Chi-square and multivariable Cox proportional regressions were conducted.

RESULTS: The overall incidence of falls over the follow-up was 27.5%; and for normal, dynapenic, abdominal obesity, and D/AO were 14.7%, 17.2%, 27.5%, and 40.4% (X2 = 8.341; P = 0.039), respectively. D/AO was associated with a higher risk of falls (hazard ratio: 3.595 [95% CI: 1.317-9.815], even after adjustments for age, body mass index, physical activity level, regular use of medications, peripheral sensation, chronic diseases, and history of lower-limbs pain.

CONCLUSIONS: D/AO is more closely related to falls than either dynapenia or abdominal obesity alone, and is independently associated with an increased incidence of falls in older women. These results provide support for the concept that the combined evaluation of muscle strength and central obesity may be clinically relevant in this population.
