“…''Dual disorders'' are common in health research and dual trajectory models provide an opportunity to study this phenomenon. Previous studies have found that concurrent sensory impairment such as vision and hearing loss increases the risk of dementia (Kuo et al, 2021b). Gopinath et al (2013) have found dual sensory impairment to be associated with increased mortality with a greater risk of death than that of vision loss or hearing loss alone.…”

Hearing loss and cognitive impairments are both highly prevalent neurological complications for older adults. While there is growing evidence to suggest that these two conditions are interrelated, little research has been conducted that directly examines the progression and developmental trajectories of these complications contemporaneously. The aim of the study is to identify the distinct trajectory profiles for hearing loss and cognitive function in an older population over a 10-year period. Through dual trajectory modeling, the interrelationship, co-occurring movements, and overlaps between these two complications were examined. We also investigated the influence of hearing aid ownership on cognitive function trajectories. We utilized longitudinal data from 1,445 participants in the Blue Mountains Hearing Study (aged 55+ years) involving repeated measures from a population-based survey with audiometric hearing assessments. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). The group-based trajectory modeling (GBTM) identified three trajectory profiles for both hearing loss and cognitive function in two older age groups (55–69 years and 70+ years). The outputs from the dual trajectories models showed the conditional probability for “no hearing loss” trajectories to be around 90% more likely to have “high-normal” cognitive function, demonstrating co-occurring overlap. In contrast, for “moderate to severe hearing loss” trajectories, the conditional probability drops to 65% and 79% for the 55–69 age group and 70+ age group respectively. There was also an increasing probability for “cognitive decline” conditional on the severity of hearing loss with 6.7%, 7.5%, and 8.7% for no hearing loss, mild hearing loss, and moderate to severe hearing loss trajectory groups. While we did not find any statistically significant difference in the influence of hearing aid use in the cognitive function trajectories, there was a consistent greater representation of non-hearing aid users in the trajectories with poorer cognitive function. This study found GBTM to identify trajectories that were in agreement with our current understanding of hearing loss and cognitive impairment in older adults. This study also adds to the existing evidence-base as dual trajectories demonstrated co-occurrence in developmental changes in these two common neurological complications for the older population.

“…2 Although it is likely that the investigators' overall conclusions remain valid, their approach may have underestimated standard errors and overestimated statistical power for their models. In a study that our group published earlier this year, 3 we reported a significant association between self-reported visual difficulty and dementia in NHATS. Like the study by Pershing et al, our analysis used data from NHATS and included up to 8 years of follow-up from 2011 to 2018.…”

“…Participants were coded as having a hearing disability if they reported being deaf or if they responded "No" to questions asking if they could hear well enough to use the telephone, carry on a conversation in a room with the TV or radio playing, and carry on a conversation in a quiet room. This method has been used in previous studies with NHATS data (Kuo et al, 2021). Individuals who self-reported vision disability or hearing disability at baseline were followed longitudinally to better understand trajectories of social isolation.…”

ObjectivesSensory disabilities, including vision disability and hearing disability, increase risk for social isolation, which is associated with multiple negative health outcomes. Existing literature suggests that the cultural value of familism may provide a buffer against social isolation. We examined the longitudinal trajectory of social isolation among Hispanic older adults with self-reported vision disability (SRVD) and self-reported hearing disability (SRHD) and tested a modified measure of social isolation incorporating familism.MethodsWe compared 8-year trajectories of social isolation among Hispanics (n = 445) and non-Hispanic Whites (n = 4,861) from the National Health and Aging Trends Study. We used structural equation modeling to explore the longitudinal relationships between sensory disability and social isolation while comparing two measures of social isolation.ResultsSocial isolation increased longitudinally for both groups, with SRVD significantly associated with higher initial levels. Social isolation started and remained higher across time among Hispanics. Using an adjusted measure of social isolation (added familial support), neither initial levels nor trajectories of social isolation differed between Hispanic and non-Hispanic White participants.DiscussionInitially, Hispanics appeared more socially isolated, reporting less social support from outside the home. Yet, we found that they were more likely to report family social connections. Traditional measures of social isolation focusing on social support outside of the home (neglecting support by family) may lack content validity among Hispanic groups. Culturally sensitive measures of social isolation will be increasingly consequential for future research and health policy to meet the needs of a diverse older population.
