Background: Disability and dementia are significant health concerns that share common risk factors, and their co-occurrence can profoundly affect the health and well-being of middle-aged and older adults. Dementia involves the decline of cognitive functions such as memory, thinking, and reasoning, while disability refers to the inability to perform essential daily activities, including seeing, hearing, walking, climbing, remembering, or concentrating. Both conditions hinder an individual's ability to manage daily life and routines. Forcibly Displaced Myanmar Nationals (FDMN), commonly known as Rohingya refugees, living in refugee camps in Bangladesh, are particularly vulnerable to physical and cognitive impairments. Despite this heightened vulnerability to social, psychological, and quality-of-life challenges, there is a lack of research exploring the impact of loneliness on disability, the relationship between disability and dementia, and the factors associated with these conditions among Rohingya refugees.
Objectives: This study aims to examine the impact of loneliness on disability among refugees residing in camps in Bangladesh. Additionally, it seeks to explore how disability influences dementia within these communities. Specifically, the study will: (a) investigate the relationship between disability and loneliness among middle-aged and older FDMN in Bangladesh; (b) explore the link between disability and dementia within this group, using existing survey data; and (c) examine the factors associated with disability and dementia among Rohingya individuals aged 50 and older living in refugee camps in Bangladesh.
Methods: To achieve these objectives, a retrospective analysis was conducted using data from the Needs and Gaps Assessment Survey. The first part of the survey included 543 FDMN, while the second part focused on 497 FDMN aged 50 and older residing in Bangladesh. Data were collected in 2020. Disability was assessed across six domains: seeing, hearing, walking, concentrating, self-care, and communication. Dementia was evaluated using the Mini Mental State Examination (MMSE), which included 11 questions covering orientation (time and place), location, registration, attention and calculation, delayed recall of three objects, naming, repetition, comprehension of simple commands, reading and obeying instructions, writing, and copying. Dementia was defined as an MMSE score of 17 or lower out of 30. Descriptive statistics were used to summarize the data, chi-square tests were conducted to examine initial associations, and logistic regression was applied to assess the relationships between variables.
Results: The average age of participants was 61.6 years (SD: 10.2). Seven out of 10 middle-aged and older FDMN had a disability. Disability was found to be associated with increasing age (OR=7.42, 95% CI: 1.70-32.45) and loneliness (OR=1.84, 95% CI: 1.02-3.30) among this group. The prevalence of dementia among middle-aged and older FDMN was 52.9%. Dementia prevalence was higher in the oldest age group (70.8%), among women (62.3%), those with two or more chronic conditions (65.4%), those living alone (56.5%), individuals with moderate acute malnutrition (81.6%), and those with disabilities (58.5%). Prevalence rates were also higher among individuals experiencing difficulties with seeing (55.5%), hearing (59.7%), walking (57.9%), concentrating (68%), self-care (72.8%), and communication (72.2%). Multivariate logistic regression analysis identified several factors associated with dementia, including age (70-79), female gender, chronic morbidities, moderate acute malnutrition, disability, and difficulties with walking, concentrating, self-care, and communication.
Conclusions: Disability was found to be associated with both advancing age and loneliness. This highlights the urgent need for practical, targeted interventions to address disability among FDMN, particularly for the high-risk subgroups identified. Dementia, on the other hand, was associated with age, gender, chronic morbidities, disability, and difficulties with walking, concentrating, self-care, and communication. The high prevalence of dementia emphasises the critical need to identify key risk factors within this population. Understanding these factors can inform the development of targeted strategies aimed at risk reduction and prevention, addressing the unmet needs of this vulnerable group.
