Abstract
PURPOSE: To quantify the association of visual field (VF) damage on physical activity away-from-home, per away-from-home excursion, and at-home.
DESIGN: Prospective cohort study.
METHODS: Among 229 participants with glaucoma or suspected glaucoma, the severity of VF damage was defined as average sensitivity within the integrated VF (IVF). Participants wore accelerometers and global po-sitioning system trackers for 7 days to measure physical activity and characterize activity location. Multivariable negative binomial regressions were used to test whether away-from-home activity per day, physical activity per away-from-home excursion, and at-home activity per day varied by the severity of VF damage.
RESULTS: Each 5-dB decrement in IVF sensitivity was associated with a lower number of away-from-home activ-ities per day (18% less moderate and vigorous physical ac-tivity [MVPA] minutes/d, 95% confidence interval, 0.690.97) and physical activities per away-from-home excursion (20% less MVPA minutes/excursion, 95% confi-dence interval, 0.65-0.98). Similar findings were noted for other away-from-home activity measures (including active minutes/steps per day, or active minutes/steps per excursion). However, worse IVF sensitivity was not asso-ciated with measures of at-home activities (MVPA min-utes/ d, active minutes/d, and steps/d), time spent at or away from home, or excursions/wk (P >.1 for all).
CONCLUSIONS: Restriction of physical activity in more patients with severe glaucoma results mostly from activity restriction outside the home environment. These findings highlight the importance of maintaining a safe home envi-ronment (where activity is less restricted) and increasing confidence to perform activity, particular high-intensity activity, when leaving the home amongst patients with glaucoma.
