Déficience visuelle et ses conséquences (troubles cognitifs, dépendance, mauvaise qualité de vie, fragilité) chez les personnes âgées en Afrique Sub-Saharienne

Abstract : Sub-Saharan Africa (SSA) is the second world region that will experience a steep increase in the number of older people within its population (+218% between 2019 and 2050). However, little attention is devoted to health issues related to aging. The main aim of this PhD thesis was to investigate the relationships between Visual Impairment (VI) and other adverse health conditions such as cognitive disorders, dependence, poor Vision-Related Quality of Life (VRQoL), and frailty among older people in SSA. To achieve this goal, several studies were conducted using data from the EPIDEMCA/FU programs. These showed that VI was very common among older people in Congo (68.8%) and that it affected daily functioning and VRQoL in this population. We also found that the residence area explained the relationship between VI and cognitive disorders in our study population without any clinical mechanism being involved (adjusted OR =1.7; 95% confidence interval: 0.6 - 4.7). Finally, focusing on older people with cognitive dysfunction, we observed that those who self-reported visual impairment were highly likely to present frailty (adjusted OR =2.2; 95% CI: 1.1 - 4.3). All these results suggest that public health actions towards prevention and promotion of management of vision issues in older people are needed to reduce the consequences of this impairment and to contribute to healthy aging of the population. Through the donation of corrective eyeglasses to older people living in Benin, we hope to bring additional evidence that will strengthen our above conclusions. Indeed, we have already prepared in this thesis a protocol for an interventional study that aims to assess the extent to which correction of VI could reduce dependence and improve VRQoL among the older people in an SSA setting.
