Abstract
BACKGROUND: There is little epidemiological evidence of sex differences in the association between dynapenic abdominal obesity and the decline in physical performance among older adults. OBJECTIVE: The aims of the present study were to investigate whether the decline in physical performance is worse in individuals with dynapenic abdominal obese and whether there are sex differences in this association. METHODS: Out of 6,183 individuals aged 60 years or older from the English Longitudinal Study of Ageing, 2,308 participants with missing data were excluded. Therefore, a longitudinal analysis was conducted with 3,875 older adults. Abdominal obesity was determined based on waist circumference (>102 cm for male and >88 cm for female) and dynapenia was based on grip strength (<26 kg for male <16 kg for female). The sample was divided into four groups: non-dynapenic/non-abdominal obesity (ND/NAO), non-dynapenic/abdominal obesity (ND/AO), dynapenic/non-abdominal obesity (D/NAO) and dynapenic/abdominal obesity (D/AO). Decline in physical performance in an eight-year follow-up period was analyzed using generalized linear mixed models. RESULTS: At baseline, both male (-1.11 points; 95% CI: -1.58, -0.65; p <0.001) and female (-1.39 points; 95% CI: -1.76, -1.02; p <0.001) with D/AO had worse performances on the Short Physical Performance Battery (SPPB) than their counterparts in the ND/NAO group. Over the eight-year follow-up, male with D/AO had a faster rate of decline in the SPPB performance compared to male in the ND/NAO group (-0.11 points per year; 95% CI: -0.21, -0.01; p = 0.03). CONCLUSION: D/AO is associated with a stronger decline in physical performance in male but not female. The identification and management of dynapenic abdominal obesity may be essential to avoiding the first signs of functional impairment in older male.
