Incidence and predictors of idiopathic pulmonary fibrosis complicating Type 2 diabetes: the Fremantle Diabetes Study Phase I

During 106 865 person-years of follow up, 17 (1.3%) Fremantle Diabetes Study Phase I participants with Type 2 diabetes and 57 (1.1%) matched individuals without diabetes developed idiopathic pulmonary fibrosis (IPF), an incidence rate ratio (95% confidence interval) of 1.40 (0.76-2.44) (P = 0.22). In the diabetes cohort, age at diabetes diagnosis and total serum cholesterol (inversely) predicted incident IPF in competing risk multivariable models. The incidence of IPF was low in community-based cohorts, regardless of Type 2 diabetes status.
