Quality of life in people with visual impairment compared with the general population

Abstract

Aim: The aim of the present study was to examine quality of life and its associated factors among adults with visual impairment in Norway. Subject and methods: Of the 1216 adults contacted, 736 (61% response rate) participated in a cross-sectional survey. A general population probability sample served as reference (n=1792, 36% response rate). Differences between the populations were examined with independent t-tests for continuous variables and with Chi-square tests for categorical variables. Quality of life covariates were investigated with linear regression analysis. Results: People with visual impairment had lower quality of life than the general Norwegian population, across all age groups (mean QOL: 6.8 versus 7.6, p<0.001) and within all age groups (all p<0.01). Compared with the general population, people with visual impairment were less likely to report the highest levels and more likely to report intermediate levels of quality of life. Higher quality of life was associated with lower onset-age of impaired vision (B=-0.11, p<0.001), having employment (B=0.36, p=0.02), lower levels of loneliness (B=-0.28, p<0.001) and higher levels of social support (B=0.40, p<0.001) and general self-efficacy (B=0.07, p<0.001). Conclusion: Quality of life was lower among people with visual impairment and may be increased by promoting work participation, social inclusion, connectedness, and coping.
