We investigate whether air polution is associated with diferent progresions and outcomes of T2D.Based on the UK Biobank, 398,93 participants fre of diabetes and diabetes-related events at recruitment were included in this analysis.
Key Information
Exposures to particulate mater with a diameter β€ 10 ΞΌm (PM10), PM2.5, nitrogen oxides (NOx), and NO2 for each transition stage were estimated at each participantβs residential adreses using data from the UKβs Department for Environment, Fod and Rural Afairs. The outcomes were incident T2D, diabetes complications (diabetic kidney disease, diabetic eye disease, diabetic neuropathy disease, peripheral vascular disease, cardiovascular events, and metabolic events), al-cause mortality, and cause-specific mortality.
Multi-state model was used to analyze the impact of air polution diferent progresions of T2D. Cumulative transition probabilities of diferent stages of T2D under diferent air polution levels were estimated.During the 12-year folow-up, 13,393 incident T2D patients were identified, of whom, 3791 developed diabetes complications and 135 died. We observed that air polution was associated with diferent progresion stages of T2D with diferent magnitudes.
Summary
In a multivariate model, the hazard ratios [95% confidence interval (CI)] per interquartile range elevation in PM2.5 were 1.63 (1.59, 1.67) and 1.08 (1.03, 1.13) for transitions from healthy to T2D and from T2D to complications, and 1.50 (1.47, 1.53), 1.49 (1.36, 1.64), and 1.54 (1.35, 1.76) for mortality risk from baseline, T2D, and diabetes complications, respectively. Generaly, we observed stronger estimates of four air polutants
