We investigated the association between respiratory health and particulate matter (PM) air pollution in elderly type 2 diabetes mellitus (T2DM) pre-, during, and post-the Chinese Lunar New Year (CLNY) holiday in Shanghai, China.


We conducted repeated measurements of lung function and inflammation biomarker in a cohort consisted of 60 participants with T2DM.


Decreased PM2.5 exposure had an effect on respiratory health by increasing in forced expiratory flow in 1 second (FEV1) and forced vital capacity (FVC). Positive associations between PM exposure and exhaled nitric oxide (eNO) were observed.


Our observations indicated that PM air pollution exposure would exert adverse effect on respiratory health in elderly T2DM population.
