Abstract Background: The purpose of this study was to estimate individuals’ expected longevity based on self-assessed survival probabilities and determine the predictors of such subjective life expectancy in a sample of elderly people in Côte d’Ivoire.Methods: Paper-based questionnaires were administered to a sample (n=267) of older adults residing in the city of Dabou, Côte d’Ivoire in May 2017. Information on subjective expectations regarding health, comorbidities, and self-assessed survival probabilities were collected. The subjective expectations were related to sociodemographic, health and lifestyle indicators. A spline-based approach was used to estimate the overall distribution of life expectancy for each individual using two to four points of self-assessed survival probabilities. A finite mixture of regression models was used to identify clusters/components of the overall subjective life expectancy distribution of the study participants. Results: The mean subjective life expectancy in older people varied according to four components/clusters. The average subjective life expectancy among the elderly was 79.51, 78.89, 80.02 and 77.79 years in the first, second, third and fourth component of the subjects' overall subjective life expectancy, respectively. The effect of sociodemographic characteristics, comorbidities, and lifestyle on subjective life expectancy varied across components. For instance, a U-shape relationship between household per capita income and subjective life expectancy was found for individuals classified into the third component, and an inverse U-shape relationship was found for individuals classified into the fourth component.Conclusion: We extended the estimation of subjective life expectancy by accounting for heterogeneity in the distribution of the estimated subjective life expectancy. This approach improved the usual methods for estimating individual subjective life expectancies and may provide insight into the elderly’s perception of aging, which could be used to forecast the demand for health services and long-term care needs.

Abstract Background The purpose of this study was to estimate individuals’ expected longevity based on self-assessed survival probabilities and determine the predictors of such subjective life expectancy in a sample of elderly people (50 years and older) in Côte d’Ivoire. Methods Paper-based questionnaires were administered to a sample (n=267) of older adults residing in the city of Dabou, Côte d’Ivoire in May 2017. Information on subjective expectations regarding health, comorbidities, and self-assessed survival probabilities were collected. We estimated self-assessed life expectancy and its determinants using a two-pronged approach by: (i) estimating individuals’ life expectancy using the self-assessed survival probabilities (SSPs), and (ii) applying a finite mixture of regression models to form homogenous groups of individuals (clusters/components) and investigate the determinants. A spline-based approach was used to estimate the overall distribution of life expectancy for each individual using two to four points of self-assessed survival probabilities. A finite mixture of regression models was used to identify homogeneous groups of individuals (i.e. clusters/components) of the overall subjective life expectancy distribution of the study participants.

Côte D'ivoire

This study proposes an analysis of the representation of the female beauty whose clear complexion is one of the illustrations in the bété. In Côte d’Ivoire, the bété shows that there was a development of the beauty through the worship of the bagnon. However, in the representation of the male beauty through the bagnon, there is no fixed color complexion. It is not the same for the beauty of the woman whose clear complexion is of significant importance. This is why this study proposes the canons of the female beauty and to question the sociocultural bases which specifically underlie the preference of the clear complexion to the black complexion of the bété woman. However, this is in a bid to understand the cultural anchoring of the female depigmentation in bété country. From a field survey of people of all social categories, the study shows that the preference of the clear complexion is explained by the fact that it would carry virtues of rejuvenation and longevity for the man. In other words, the beauty of the woman aims at developing the man by rejuvenating him and by lengthening his life expectancy. These imaginations results to the depigmentation of the young girls and women bété in their search for beauty. This they do via the clear complexion to make them more attractive to men.

Nucleic Acid Tests

Abstract Introduction The World Health Organization (WHO) HIV diagnostic strategy requires six rapid diagnostic tests (RDTs). Point-of-care nucleic acid tests (POC NATs) are costlier, less sensitive, but more specific than RDTs. Methods We simulated a one-time screening process in Côte d’Ivoire (CI; undiagnosed prevalence: 1.8%), comparing WHO- and CI-recommended RDT-based strategies (RDT-WHO, RDT-CI) and an alternative: POC NAT to resolve RDT discordancy (NAT-Resolve). Costs included assays (RDT: $1.47; POC NAT: $27.92); ART ($6–22/month); HIV care ($27–38/month). We modeled two sensitivity/specificity scenarios: high-performing (RDT: 99.9%/99.1%; POC NAT: 95.0%/100.0%) and low-performing (RDT: 91.1%/82.9%; POC NAT: 93.3%/99.5%). Outcomes included true/false positive/negative (TP, TN, FP, FN) results, life expectancy, costs, and incremental cost-effectiveness ratios (ICERs: $/year-of-life saved [YLS]; threshold ≤$1,720/YLS [per-capita GDP]). Results Model-projected impacts of misdiagnoses were: 4.4y lost (FN versus TP; range: 3.0–13.0y) and a $5,800 lifetime cost increase (FP versus TN; range: $590–$14,680). In the high-performing scenario, misdiagnoses/10,000,000 tested were lowest for NAT-Resolve versus RDT-based strategies (FN: 409 versus 413–429; FP: 14 versus 21–28). Strategies had similar life expectancy (228 months) and lifetime costs ($220/person) among all tested; ICERs were $3,450/YLS (RDT-CI versus RDT-WHO) and $120,910/YLS (NAT-Resolve versus RDT-CI). In the low-performing scenario, misdiagnoses were higher (FN: 22,845–30,357; FP: 83,724–112,702) and NAT-Resolve was cost-saving. Conclusions We projected substantial clinical and economic impacts of misdiagnoses. Using POC NAT to resolve RDT discordancy generated the fewest misdiagnoses, was not cost-effective in high-performing scenarios, but may be an important adjunct to existing RDT-based strategies in low-performing scenarios.
