On follow-up (24±18 months), 18 individuals showed progression which was associated with gastro-oesophageal reflux disease (OR 4.1, 95% CI 1.2–12.9; p=0.02) and in females with diabetes mellitus (OR 5.3, 95% CI 1.0–27.4; p=0.01).Conclusions Around 10% of respiratory asymptomatic individuals enrolled in our lung ageing programme show ILAs. Increased serum concentrations of pro-inflammatory molecules and MMPs are associated with ILAs.Some individuals older than 50 years may present interstitial lung abnormalities which are associated with a greater risk of all-cause mortality. This study provides demographic and molecular factors which may help to identify individuals at higher risk. https://bit.ly/2Lc4y88 ER -
