AIM: To study the correlation between type A behavior and dry eye.

METHODS: Here we used case-control study,100 dry eye patients and 100 healthy persons all completed the questionnaire of type A behavior and unified questionnaire. The results were analyzed by univariate and multivariate conditional logistic regression analysis.

RESULTS: There was significant difference on distribution of behavior pattern between dry eye group and normal group(χ²=6.494,P=0.011). After one factor logistic regression analysis, the risk of dry eye for people with type A behavior was higher(OR=2.296, 95%CI:1.202-4.384, P=0.012); that for people using visual display terminal more than 6h was 2.992(95%CI:1.668-5.369, P<0.01); that for people staying in air condition room was 2.631(95%CI: 1.472-4.702, P=0.001). After multivariate conditional logistic regression analysis, compared with type B behavior, type A behavior pattern(OR=2.659,95%CI:1.335-5.295,P=0.005), people using visual display terminal more than 6h(OR=2.264, 95%CI: 1.166-4.396, P=0.016), people staying in air condition room(OR=2.053, 95%CI: 1.048～4.020, P=0.036)were more significantly associated with dry eye.

CONCLUSION: Type A behavior pattern, using visual display terminal more than 6h and staying in air condition room may be independent risk factors for dry eye.
