Cognitive function was assessed via episodic memory and mental integrity. Sarcopenia status was diagnosed according to the criteria of the AWGS 2019. General linear regression models were applied to investigate the association between WC, sarcopenia, their combined effects and cognitive function. Mediation analysis was used to access the mediating effect of WC in the relationship between sarcopenia and cognitive function. The nonlinear association between WC and cognitive function was explored by using the restricted cubic spline model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 5577 participants, the average cognitive score was 12.41. After controlling for confounding factors, participants with central obesity and severe sarcopenia had the worst cognitive scores (\u03b2\u2009=\u2009\u22123.22, 95%CI\u2009=\u2009\u22124.81, \u22121.61). WC mediated 16.95% of the association between sarcopenia and cognitive scores, and 9.26% of the association between severe sarcopenia and cognitive scores. The strongest positive association was found between WC and cognitive scores when WC was 96.74\u2005cm in men.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Central obesity was associated with better cognitive function.
