  1. RR: risk ratio, CI: confidence interval. a Variables included in the model 1 were vision and hearing impairments. bIn addition to the model 1, age (continuous), education, marital status, smoking, alcohol consumption, past/current history of major illness and diabetes mellitus were included. For combined-gender analysis, we further adjusted for gender.cStatistical interaction between sensory impairments and gender with a likelihood ratio test.
