Abstract

Background: Sitting time and physical activity are related to renal function among type 2 diabetes mellitus (T2DM); however, the mechanism of how it contributes to renal function is not well understood. The current study attempts to explore the relationship between sitting time and renal function among T2DM patients, with a particular focus on the mediating role of physical activity.

Methods: This research uses the data of 1761 Chinese T2DM patients from Ningxia Province. Sitting time and physical activity were obtained during a face-to-face survey, and renal function was assessed by the estimated glomerular filtration rate (eGFR). The bootstrap method is used to test the mediating effect.

Results: The research found that sitting time was negatively associated with eGFR and physical activity after controlling for covariates. Physical activity was positively associated with eGFR. Physical activity has mediated the relationship between sitting time and eGFR among T2DM patients (explaining 16.1% of the total variance).

Conclusion: The present findings suggest that sitting time negatively affects eGFR among T2DM patients and provides new evidence that physical activity could attenuate the association between sitting time and eGFR. Hence, intervention strategies focusing on sitting time and physical activity should be paid more attention in the future.
