Background & aims: Coexistence of obesity and decreased muscle strength, defined as sarcopenic obesity, is often observed in the older adults. The present study investigated whether sarcopenic obesity, defined as reduced handgrip strength and increased body mass index (BMI), is associated with cognitive impairment.Methods: Study participants include 1615 older adults aged 65-84 years who lived in an urban area of Tokyo, Japan and participated in the Bunkyo Health Study. Mild cognitive impairment (MCI) and dementia were defined based on <= 22 points of Montreal Cognitive Assessment and <= 23 points of the Mine Mental State Examination, respectively. Handgrip strength was measured using a dynamometer in a standing position. We divided participants into four groups according to their sarcopenia (probable) (handgrip strength <28 kg in men and <18 kg in women) and obesity status (BMI >= 25 kg/m(2)) as control, obesity, sarcopenia and sarcopenic obesity, and investigated the association between cognitive function, sarcopenia, and obesity status.Results: Mean age was 73.1 +/- 5.4 years, and 57.6% of study participants were female. The prevalence of control, obesity, sarcopenia, and sarcopenic obesity was 59.4%, 21.2%, 14.6%, and 4.7%, respectively. The prevalence of MCI and dementia, respectively, was highest in participants with sarcopenic obesity, followed by those with sarcopenia, obesity, and control. After multivariate adjustment, sarcopenic obesity was independently associated with increased odds of MCI and dementia compared with the control (MCI: 2.11 [95% confidence interval, 1.12-3.62]; dementia: 6.17 [2.50-15.27]).Conclusions: Sarcopenic obesity was independently associated with MCI and dementia among Japanese older adults. Future studies are necessary to clarify the causal relationship. (C) 2022 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.
