Demographic and lifestyle risk factors of dry eye disease subtypes: A cross-sectional study.

Abstract

PURPOSE\nTo evaluate demographic and lifestyle factors associated with aqueous deficient and evaporative dry eye disease.\n\n\nMETHODS\nA total of 1125 general public visitors (707 females, mean\u202f±\u202fSD age, 33\u202f±\u202f21, range 5-90 years) at the Royal Society Summer Science Exhibition were recruited in a cross-sectional study. A demographic and lifestyle factor questionnaire was administered, and dry eye symptomology (DEQ-5 score), ocular surface characteristics (conjunctival hyperaemia, and infrared meibography), and tear film parameters (tear meniscus height, non-invasive breakup time, and lipid layer grade) were evaluated for each participant within a single session. The diagnostic criteria for dry eye disease subtypes were adapted from the rapid non-invasive dry eye assessment algorithm.\n\n\nRESULTS\nOverall, 428 (38%) participants fulfilled the diagnostic criteria for dry eye disease, 161 (14%) with aqueous deficient dry eye disease, and 339 (30%) with evaporative dry eye disease. Multivariate logistic regression demonstrated that advancing age, female sex, reduced sleep duration, increased psychological stress, and poorer self-perceived health status were independently associated with aqueous deficient dry eye disease (all p\u202f<\u202f0.05). Significant risk factors for evaporative dry eye disease included advancing age, East and South Asian ethnicity, contact lens wear, increased digital device screen exposure, higher psychological stress, and poorer self-perceived health status (all p\u202f<\u202f0.05).\n\n\nCONCLUSIONS\nBoth subtypes of dry eye disease were associated with several unique and shared demographic and lifestyle factors. The findings of this study could inform future research design investigating the utility of targeted screening and risk factor modification for the prevention and management of dry eye disease.
