Association of nonrefractive visual impairment with risk of all-cause and specific-cause mortality in the National Health and Nutrition Examination Survey, 1999 to 2008.

ABSTRACT:

Objective

To investigate and describe the impact of nonrefractive visual impairment (NVI) and its severity on all-cause and cause-specific mortality, along with the latest estimations.

Methods

Cox proportional hazards regression models with multiple covariate adjustments and Fine-Gray competing risk regression models assessed the risk of all-cause and specific-cause mortality. Propensity score matching (PSM) was employed to achieve covariate balance.

Results

Among 7 961 participants (representing 171 383 125 non-institutionalized US individuals), baseline NVI was present in 350 participants (4.40%), with 313 (3.93%) having mild NVI and 37 (0.47%) having severe NVI. Both any NVI and Severe NVI were associated with increased all-cause and diabetes mellitus (DM)-related
