The Association between Dry Eye Disease and Physical Activity as well as Sedentary Behavior: Results from the Osaka Study

Abstract EN

Purpose.

To assess the association of dry eye disease (DED) with physical activity and sedentary behavior.

Methods.

The cross-sectional survey conducted included Japanese office workers who use visual display terminals ( n = 672 ).

DED was assessed according to the Japanese Dry Eye Diagnostic Criteria, and participants were categorized into “definite DED,” “probable DED,” or “non-DED” groups based on the results of DED examinations.

Physical activity and sedentary behavior of participants were assessed using the International Physical Activity Questionnaire (IPAQ), and physical activity level was calculated in metabolic equivalent units per week (MET, min/week).

Participants were classified as having a high, moderate, or low level of physical activity.

Results.

Participants with abnormal tear break-up time (BUT) (≤5 s) were involved in sedentary behavior for significantly longer duration than those with normal BUT ( P = 0.

035 ).

Non-DED participants (14.5%) tended to have higher levels of physical activity than definite DED participants (2.5%).

Participants with definite DED had significantly lower MET scores than those with non-DED ( P = 0.

025 ).

Conclusions.

Our findings suggest that a lower level of physical activity and sedentary behavior are associated with DED; however, longitudinal/intervention studies with large groups of participants are needed to validate these findings.
