Nitrogen dioxide exposure attenuates or even reverses the association between physical activity and fasting plasma glucose levels in non-diabetic elderly Chinese adults.

ABSTRACT:

Background

The combined effects of physical activity (PA) and nitrogen dioxide (NO₂) on fasting plasma glucose (FPG) levels have rarely been studied. This study aimed to examine whether long-term exposure to NO₂ attenuates the association between PA and FPG levels in non-diabetic older adults.

Methods

A total of 2600 non-diabetic elderly Chinese adults were included in this cross-sectional study. PA data were collected using the International Physical Activity Questionnaire (IPAQ). The Space-Time Extra-Trees model was utilized to estimate the annual concentration of NO₂. General linear regression models were used to assess independent and interaction associations of long-term exposure to NO₂ and PA with FPG levels. An interaction p
