To investigate the epidemiological characteristics of sarcopenic obesity (SO) among community-dwelling older adults aged 60 years and above, to analyze the associations between physical activity and other influencing factors with SO, and to explore their predictive effects, providing evidence for the prevention and management of sarcopenic obesity.
Community-dwelling adults aged ≥60 years in Chengdu, Sichuan Province, were recruited using cluster random sampling and convenience sampling. Physical activity data were collected through questionnaires and body composition assessments, and physical activity levels were categorized accordingly. Based on the diagnostic criteria of the Asian Working Group for Sarcopenia (AWGS), participants were classified into an SO group and a non-SO sarcopenia group.Multivariable logistic regression and restricted cubic spline analyses were conducted to examine the association between physical activity and SO.
A total of 7 862 participants were included, comprising 941 individuals with SO (11.97%) and 1 339 with non-SO sarcopenia (17.03%). The SO group had the lowest weekly physical activity level (3 360.00 [1 680.00, 5 880.00] MET-min/week), with the highest proportion of low physical activity (91.4%) and the lowest proportion of high physical activity (2.1%). Subgroup analysis by sex revealed that moderate physical activity was a protective factor against SO in women (OR=0.58, 95%CI=0.35-0.96).
Physical activity may be associated with sarcopenic obesity. Increasing physical activity levels could reduce the risk of SO and play an important role in its prevention.
