Assessing the Joint Prevalence of Dementia and Hearing Loss in Scotland: An Epidemiological Model for Public Health Planning
(Springer, 2023-08-03) Koesters, Nils Bernd; McMenemy, Andrena; Johnson, Christine
Aim: Data in Public Health studies often comes in mismatched age groups. This study investigated how mathematical modeling techniques could be used to estimate the number of individuals with dementia and hearing loss in Scotland given heterogeneous age group data. Subject and Methods: Using established criteria for modeling hearing loss, current population level estimates from the Scottish National Records office were employed to calculate general estimates of the number of individuals with hearing loss in Scotland. Additionally, age group models developed by the European Collaboration on Dementia were used to generate estimates of the number of people with dementia in Scotland. To estimate the number of individuals with both conditions, the two models were combined in a single formula. Parameter optimization was performed on various growth models to determine the best fit to the data. Results: The Stannard growth model was found to be the best fit to the data. Conclusion: The prevalence of hearing loss, dementia, and their co-occurrence exhibit a sigmoidal pattern, which is well-captured by the Stannard growth model, a logistic, sigmoidal type model. This study demonstrates the potential of mathematical modeling to provide nuanced and robust estimates of the prevalence of hearing loss, dementia, and their co-occurrence given heterogeneous data sources. A lookup table is provided.
Deafness and Dementia: Predicting the future for Scotland

Deafness: Predicting the future for Scotland

The exact numbers of deaf people in Scotland varies depending upon which source is consulted. This lack of clarity is problematic when it comes to planning for delivery of future services and it is widely recognised that there is a need to establish better reporting procedures in order to capture relevant statistics. To this end, this research has sought to investigate the source with which the Scottish Government makes policy decisions; the source that is used to ‘allocate resources and plan services’ in Scotland: The 2011 Census for Scotland (Office for National Statistics 2011). As the next Census will be taken in 2021, it would seem timely to look at what information this source currently offers on the prevalence of hearing loss in Scotland and how far it relates to the wider picture. How far does the above definition of the aims and objectives of the Census fit to enable precise data to be captured and recorded and as a result ensure optimum service planning and provision for those with hearing loss in Scotland?

Visualizing Worldwide Prevalence of Age-Related Dual Sensory Loss
(SAGE Publications, 2024-06-23) Koesters, Nils; Minhas, R; Wittich, Walter; McMenemy, Andrena; Johnson, Christine
Objectives: This study aims to create a first visualization of global prevalence of age-related dual sensory loss (DSL), significantly affecting older people’s quality of life. Methods: Data from World Health Organization (WHO) regions, particularly African, American, and European, were analyzed. The study focused on DSL onset and prevalence, using adjusted life expectancy for regional comparison. Results: There were notable regional variations in DSL onset and prevalence. The African region showed consistent data, thanks to standardized methods from the World Federation of the Deafblind. However, global patterns varied when adjusted for life expectancy, hinting at possible DSL prevalence stabilization at older ages. Discussion: The study identifies a lack of standardization in DSL prevalence research regarding definitions, methodologies, and reporting. It calls for more uniform and thorough research methods for accurate global DSL understanding. The research highlights the complexity and challenges in determining DSL prevalence worldwide.
