  abstract = {{I}ntroduction: {I}n sub-{S}aharan {A}frica, many older people experience vision impairment ({VI}) and its adverse health outcomes. {I}n this study, we examined separately the association between {VI} and each adverse health conditions (cognitive disorders, vision-related quality of life [{VRQ}o{L}], and daily functioning interference [{DFI}]) among {C}ongolese older people. {W}e also explored whether {VI} had a significant effect on {VRQ}o{L} components in our population. {M}ethod: {W}e performed cross-sectional analyses on data from 660 {C}ongolese people aged 65 years who participated in the 2013 survey of the {EPIDEMCA} population-based cohort study. {VI} was defined as having a near visual acuity <20/40 (assessed at 30 cm using a {P}arinaud chart). {C}ognitive disorders were assessed using neuropsychological tests and neurological examinations. {VRQ}o{L} was assessed using a reduced version of the {N}ational {E}ye {I}nstitute {V}isual {F}unction {Q}uestionnaire ({VFQ}-22) and {DFI} using 11 items of participation restrictions and activity limitations. {R}egarding our main objective, each association was explored separately using multivariable logistic and linear regression models. {A}dditionally, the effects of {VI} on each {VRQ}o{L} components were explored using univariable linear regression models. {R}esults: {VI} was not associated with cognitive disorders after adjustment for residence area (adjusted odds ratio = 1.7; 95% confidence interval [{CI}]: 0.6; 4.7), but it was associated with a low {VRQ}o{L} score (adjusted  = 12.4; 95% {CI}: 17.5; 7.3) even after controlling for several covariates. {A}n interaction between {VI} and age (p = 0.007) was identified, and {VI} was associated with {DFI} only among people aged >73 years (adjusted  = 0.5; 95% {CI}: 0.2; 0.8). {O}ur exploratory analysis showed that all components of {VRQ}o{L} decreased with a decrease in visual acuity (corrected p 0.05). {C}onclusion: {VI} was associated with poor {VRQ}o{L} and high {DFI}. {R}esidence area seems to play a confounding role in the association between {VI} and cognitive disorders. {O}ur findings suggest that targeting interventions on vision could reduce {DFI} among older people and improve their well-being.},
