Combination of dynapenia and abdominal obesity affects long-term physical performance trajectories in older adults: sex differences.

ABSTRACT:

Background

There is little epidemiological evidence of sex differences in the association between dynapenic abdominal obesity and the decline in physical performance in older adults.

Objectives

The aims of the present study were to investigate whether the decline in physical performance is worse in individuals with dynapenic abdominal obesity and whether there are sex differences in this association.

Methods

Of 6183 individuals aged ≥60 y from the English Longitudinal Study of Ageing, 2308 participants with missing data were excluded. Therefore, a longitudinal analysis was conducted with 3875 older adults. Abdominal obesity was determined based on waist circumference (>102 cm for males, and >88 cm for females), and dynapenia was based on grip strength (<26 kg for males, <16 kg for female). The sample was divided into 4 groups: nondynapenic/nonabdominal obesity (ND/NAO), nondynapenic/abdominal obesity (ND/AO), dynapenic/nonabdominal obesity (D/NAO), and dynapenic/abdominal obesity (D/AO). Decline in physical performance in an 8-y follow-up period was analyzed using generalized linear mixed models.

Results

At baseline, both male (-1.11 points; 95% CI: -1.58, -0.65 points; P < 0.001) and female (-1.39 points; 95% CI: -1.76, -1.02 points; 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 8-y follow-up, males with D/AO had a faster rate of decline in the SPPB performance compared with males in the ND/NAO group (-0.11 points/y; 95% CI: -0.21, -0.01 points; P = 0.03).

Conclusions

D/AO is associated with a stronger decline in physical performance in males but not in females. The identification and management of dynapenic abdominal obesity could be essential to avoiding the first signs of functional impairment in older males.

Project description:BACKGROUND/OBJECTIVES:The concept of dynapenic obesity has been gaining great attention recently. However, there is little epidemiological evidence demonstrating that dynapenic abdominal obese individuals have worse trajectories of disability than those with dynapenia and abdominal obesity alone. Our aim was to investigate whether dynapenia combined with abdominal obesity can result in worse trajectories of instrumental activities of daily living (IADL) among English and Brazilian older adults over eight and ten years of follow-up, respectively. METHODS:We used longitudinal data from 3374 participants from the English Longitudinal Study of Ageing (ELSA) and 1040 participants from the Brazilian Health, Well-being and Aging Study (SABE) who were free from disability as assessed by IADL at baseline. IADL disability was defined herein as a difficulty to perform the following: preparing meals, managing money, using transportation, shopping, using the telephone, house cleaning, washing clothes, and taking medications according to the Lawton IADL modified scale. The study population in each country was categorized into non-dynapenic/non-abdominal obese (reference group), abdominal obese, dynapenic and dynapenic abdominal obese according to their handgrip strength (<26 kg for men and <16 kg for women) and waist circumference (>102 cm for men and >88 cm for women). We used generalized linear mixed models with IADL as the outcome. RESULTS:The estimated change over time in IADL disability was significantly higher for participants with dynapenic abdominal obesity compared to those with neither condition in both cohorts (ELSA: +0.023, 95% CI = 0.012-0.034, p < 0.001; SABE: +0.065, 95% CI = 0.038-0.091, p < 0.001). Abdominal obesity was also associated with changes over time in IADL disability (ELSA: +0.009, 95% CI = 0.002-0.015, p < 0.05; SABE: +0.021, 95% CI = 0.002-0.041, p < 0.05), which was not observed for dynapenia. CONCLUSIONS:Abdominal obesity is an important risk factor for IADL decline but participants with dynapenic abdominal obesity had the highest rates of IADL decline over time among English and Brazilian older adults.
