Physical inactivity, prolonged sedentary behaviors, and use of visual display terminals as potential risk factors for dry eye disease: JPHC-NEXT study

Abstract Purpose This population-based, cross-sectional study was performed to assess the influence of life-style modalities, including physical activity, sedentary behaviors, and visual display terminal (VDT) use, on the prevalence of dry eye disease (DED). Methods The study included a total of 102,582 participants aged 40–74 years, from the Japan Public Health Center-based Prospective Study for the Next Generation, a large nationwide prospective ongoing Japanese cohort study. Logistic regression analyses were used to investigate the relationship of total and leisure-time physical activity, duration of sedentary behaviors, and VDT use (hours/day) with DED. Results Among 47,346 men and 55,236 women, 25,234 (8315 males and 16,919 females) cases of DED were documented. Total physical activity was significantly related to decreased DED in both sexes; for the highest vs. lowest total physical activity quartiles, the multivariable-adjusted odds ratios (ORs) for DED were 0.90 (95% confidence interval [CI], 0.84–0.97; Ptrend Conclusions Physical inactivity, prolonged sedentary behaviors, and use of VDT were related to increased susceptibility to DED among middle-aged to older Japanese adults.
