Association of life-style with intraocular pressure in middle-aged and older Japanese residents.
OBJECTIVE
To evaluate the associations of several life-style-related factors with intraocular pressure (IOP).


METHODS
Of a total of 649 men and women who had been examined in an annual health check-up being conducted by a general hospital in Ibaraki prefecture, Japan, 569 individuals (age range, 29-79 years) who had not undergone any medical treatment for hypertension, ocular hypertension, or glaucoma, were selected as the subjects of this study. The associations of several life-style-related factors with the IOP were evaluated by multiple regression analyses and analyses of covariance.


RESULTS
Body mass index (BMI), alcohol consumption score, and cigarette consumption were found to have a significantly positive association with the IOP in men (P for trend =.002, <.001, and <.001, respectively). In women also, the BMI was positively related to the IOP (P for trend =.071). In respect to the effects of coffee consumption, it was shown that in men the mean IOP adjusted for age, the BMI, alcohol intake score, cigarette consumption, and blood pressure were significantly lower in habitual coffee drinkers than in coffee abstainers (P =.016).


CONCLUSIONS
The results of this study suggest that the IOP level may be substantially affected by daily life-style among Japanese.
