Early-Onset Physical Frailty in Adults With Diabesity and Peripheral Neuropathy.

ABSTRACT

OBJECTIVES: Diabesity (obesity and diabetes mellitus) has been identified as a potential contributor to early-onset frailty. Impairments contributing to early onset of physical frailty in this population are not well understood, and there is little evidence of the impact of peripheral neuropathy on frailty. The purpose of this study was to determine impairments that contribute to early-onset physical frailty in individuals with diabesity and peripheral neuropathy. METHODS: We studied 105 participants, 82 with diabesity and peripheral neuropathy (57 years of age, body mass index [BMI] 31 kg/m2); 13 with diabesity only (53 years of age, BMI 34 kg/m2) and 10 obese controls (67 years of age, BMI 32 kg/m2). Peripheral neuropathy was determined using Semmes Weinstein monofilaments; physical frailty was classified using the 9-item, modified Physical Performance Test; and knee extension and ankle plantarflexion peak torques were measured using isokinetic dynamometry. RESULTS: Participants with diabesity and peripheral neuropathy were 7.4 times more likely to be classified as physically frail. Impairments in lower-extremity function were associated with classification of frailty. CONCLUSIONS: Individuals with diabesity and peripheral neuropathy are particularly likely to be classified as frail. Earlier identification and interventions aimed at improving lower-extremity function may be important to mitigate the early-onset functional decline.
