Item Open Access Association Between Hearing Handicap and Life-Space Mobility in a Patient Population.(American journal of audiology, 2023-06) Oliva, Allison; West, Jessica S; Smith, Sherri L; Huang, Ryan J; Riska, Kristal MPurpose
The purpose of this study was to evaluate the association between self-reported hearing handicap and life-space mobility utilizing the Life-Space Questionnaire (LSQ). Life-space mobility reflects how an individual moves through their daily physical and social environment, and the role of hearing loss in life-space mobility is not fully understood. We hypothesized that those with higher self-reported hearing handicap would be more likely to demonstrate restricted life-space mobility.Method
A total of 189 older adults (M age = 75.76 years, SD = 5.81) completed a mail-in survey packet including the LSQ and Hearing Handicap Inventory for the Elderly (HHIE). Participants were categorized into one of three groups ("no/none," "mild/moderate," or "severe" hearing handicap) according to HHIE total score. LSQ responses were dichotomized to either "nonrestricted/typical" or "restricted" life-space mobility groups. Logistic regression models were performed to analyze life-space mobility differences among the groups.Results
Logistic regression results demonstrated no statistically significant association between hearing handicap and LSQ.Conclusions
The results of this study indicate that there is no association between self-reported hearing handicap and life-space mobility as evaluated using a mail-in version of the LSQ. This counters other studies that have demonstrated that life space is associated with chronic illness, cognitive functioning, and social and health integration.Item Open Access Demographic and Socioeconomic Disparities in Life Expectancy With Hearing Impairment in the United States.(The journals of gerontology. Series B, Psychological sciences and social sciences, 2021-04) West, Jessica S; Lynch, Scott MObjectives
Hearing impairment is one of the most common disabilities among older people, and its prevalence will increase as the U.S. population ages. However, little is known about social disparities in onset or transitions into and out of hearing impairment, nor how these transitions impact years of life to be spent impaired.Method
We investigate the number of years an "average" person can expect to live with and without hearing impairment after age 50; sex, race, educational, and regional differences in these expectancies; and the implication of hearing impairment for remaining life expectancy. Bayesian multistate life table methods are applied to 9 waves of data from the Health and Retirement Study (1998-2014) to investigate social disparities in life expectancy with hearing impairment (n = 20,200) for the general population, people hearing impaired at age 50, and people hearing unimpaired at age 50.Results
Men, Hispanics, persons with less educational attainment, and those born in the south can expect to live a larger proportion of their remaining lives hearing impaired. Although transitions from hearing impaired to unimpaired occur, those with some hearing impairment at age 50 can expect to live more years with hearing impairment, and hearing impairment does not shorten remaining life expectancy.Discussion
Significant sociodemographic disparities in hearing impaired life expectancy exist. In contrast to past research, we find that hearing impairment does not affect total life expectancy. Future research should consider the consequences of hearing impairment for years to be lived with other age-related and potentially downstream health outcomes.Item Open Access Hearing impairment, social support, and depressive symptoms among U.S. adults: A test of the stress process paradigm(Social Science and Medicine, 2017-11) West, JSHearing impairment is a growing physical disability affecting older adults and is an important physical health stressor, but few studies have examined it in relation to mental health outcomes and even fewer have considered the role of social support in buffering this relationship. The current study builds on the stress process framework and uses longitudinal data from three waves of the Health and Retirement Study (2006, 2010, 2014) to examine the relationship between hearing impairment and depressive symptoms among U.S. adults aged 50 and older (n = 6075). The analysis uses fixed-effects models to assess this relationship and examine the extent to which social support mediates (buffers) or moderates (interaction) the association. The results found that worse self-rated hearing was associated with a significant increase in depressive symptoms, even after controlling for sociodemographic factors. Social support did not buffer this relationship. Instead, social support interacted with hearing impairment: low levels of social support were associated with more depressive symptoms but only among people with poor self-rated hearing. Among those with excellent self-rated hearing, low levels of social support did not increase depressive symptoms. Moreover, high levels of social support reduced depressive symptoms for those with poor hearing. These findings suggest that hearing impairment is a chronic stressor in individuals' lives, and that responses to this stressor vary by the availability of social resources.Item Open Access Impact of Hearing Aid Use on Falls and Falls-Related Injury: Results From the Health and Retirement Study.(Ear and hearing, 2022-03) Riska, Kristal M; Peskoe, Sarah B; Kuchibhatla, Maragatha; Gordee, Alexander; Pavon, Juliessa M; Kim, Se Eun; West, Jessica S; Smith, Sherri LObjectives
Falls are considered a significant public health issue and falls risk increases with age. There are many age-related physiologic changes that occur that increase postural instability and the risk for falls (i.e., age-related sensory declines in vision, vestibular, somatosensation, age-related orthopedic changes, and polypharmacy). Hearing loss has been shown to be an independent risk factor for falls. The primary objective of this study was to determine if hearing aid use modified (reduced) the association between self-reported hearing status and falls or falls-related injury. We hypothesized that hearing aid use would reduce the impact of hearing loss on the odds of falling and falls-related injury. If hearing aid users have reduced odds of falling compared with nonhearing aid users, then that would have an important implications for falls prevention healthcare.Design
Data were drawn from the 2004-2016 surveys of the Health and Retirement Study (HRS). A generalized estimating equation approach was used to fit logistic regression models to determine whether or not hearing aid use modifies the odds of falling and falls injury associated with self-reported hearing status.Results
A total of 17,923 individuals were grouped based on a self-reported history of falls. Self-reported hearing status was significantly associated with odds of falling and with falls-related injury when controlling for demographic factors and important health characteristics. Hearing aid use was included as an interaction in the fully-adjusted models and the results showed that there was no difference in the association between hearing aid users and nonusers for either falls or falls-related injury.Conclusions
The results of the present study show that when examining self-reported hearing status in a longitudinal sample, hearing aid use does not impact the association between self-reported hearing status and the odds of falls or falls-related injury.Item Open Access Rare hereditary COL4A3/COL4A4 variants may be mistaken for familial focal segmental glomerulosclerosis.(Kidney Int, 2014-12) Malone, Andrew F; Phelan, Paul J; Hall, Gentzon; Cetincelik, Umran; Homstad, Alison; Alonso, Andrea S; Jiang, Ruiji; Lindsey, Thomas B; Wu, Guanghong; Sparks, Matthew A; Smith, Stephen R; Webb, Nicholas JA; Kalra, Philip A; Adeyemo, Adebowale A; Shaw, Andrey S; Conlon, Peter J; Jennette, J Charles; Howell, David N; Winn, Michelle P; Gbadegesin, Rasheed AFocal segmental glomerulosclerosis (FSGS) is a histological lesion with many causes, including inherited genetic defects, with significant proteinuria being the predominant clinical finding at presentation. Mutations in COL4A3 and COL4A4 are known to cause Alport syndrome (AS), thin basement membrane nephropathy, and to result in pathognomonic glomerular basement membrane (GBM) findings. Secondary FSGS is known to develop in classic AS at later stages of the disease. Here, we present seven families with rare or novel variants in COL4A3 or COL4A4 (six with single and one with two heterozygous variants) from a cohort of 70 families with a diagnosis of hereditary FSGS. The predominant clinical finding at diagnosis was proteinuria associated with hematuria. In all seven families, there were individuals with nephrotic-range proteinuria with histologic features of FSGS by light microscopy. In one family, electron microscopy showed thin GBM, but four other families had variable findings inconsistent with classical Alport nephritis. There was no recurrence of disease after kidney transplantation. Families with COL4A3 and COL4A4 variants that segregated with disease represent 10% of our cohort. Thus, COL4A3 and COL4A4 variants should be considered in the interpretation of next-generation sequencing data from such patients. Furthermore, this study illustrates the power of molecular genetic diagnostics in the clarification of renal phenotypes.Item Open Access Rare variants create synthetic genome-wide associations.(PLoS Biol, 2010-01-26) Dickson, Samuel P; Wang, Kai; Krantz, Ian; Hakonarson, Hakon; Goldstein, David BGenome-wide association studies (GWAS) have now identified at least 2,000 common variants that appear associated with common diseases or related traits (http://www.genome.gov/gwastudies), hundreds of which have been convincingly replicated. It is generally thought that the associated markers reflect the effect of a nearby common (minor allele frequency >0.05) causal site, which is associated with the marker, leading to extensive resequencing efforts to find causal sites. We propose as an alternative explanation that variants much less common than the associated one may create "synthetic associations" by occurring, stochastically, more often in association with one of the alleles at the common site versus the other allele. Although synthetic associations are an obvious theoretical possibility, they have never been systematically explored as a possible explanation for GWAS findings. Here, we use simple computer simulations to show the conditions under which such synthetic associations will arise and how they may be recognized. We show that they are not only possible, but inevitable, and that under simple but reasonable genetic models, they are likely to account for or contribute to many of the recently identified signals reported in genome-wide association studies. We also illustrate the behavior of synthetic associations in real datasets by showing that rare causal mutations responsible for both hearing loss and sickle cell anemia create genome-wide significant synthetic associations, in the latter case extending over a 2.5-Mb interval encompassing scores of "blocks" of associated variants. In conclusion, uncommon or rare genetic variants can easily create synthetic associations that are credited to common variants, and this possibility requires careful consideration in the interpretation and follow up of GWAS signals.Item Open Access Revealing Hearing Loss: A Survey of How People Verbally Disclose Their Hearing Loss.(Ear and hearing, 2016-03) West, Jessica S; Low, Jacob CM; Stankovic, Konstantina MObjective
Hearing loss is the most common sensory deficit and congenital anomaly, yet the decision-making processes involved in disclosing hearing loss have been little studied. To address this issue, we have explored the phrases that adults with hearing loss use to disclose their hearing loss.Design
Since self-disclosure research has not focused on hearing loss-specific issues, we created a 15-question survey about verbally disclosing hearing loss. English speaking adults (>18 years old) with hearing loss of any etiology were recruited from otology clinics in a major referral hospital. Three hundred and thirty-seven participants completed the survey instrument. Participants' phrase(s) used to tell people they have hearing loss were compared across objective characteristics (age; sex; type, degree, and laterality of hearing loss; word recognition scores) and self-reported characteristics (degree of hearing loss; age of onset and years lived with hearing loss; use of technology; hearing handicap score).Results
Participants' responses revealed three strategies to address hearing loss: Multipurpose disclosure (phrases that disclose hearing loss and provide information to facilitate communication), Basic disclosure (phrases that disclose hearing loss through the term, a label, or details about the condition), or nondisclosure (phrases that do not disclose hearing loss). Variables were compared between patients who used and who did not use each disclosure strategy using χ or Wilcoxon rank sum tests. Multipurpose disclosers were mostly female (p = 0.002); had experienced reactions of help, support, and accommodation after disclosing (p = 0.008); and had experienced reactions of being overly helpful after disclosing (p=0.039). Basic disclosers were predominantly male (p = 0.004); reported feeling somewhat more comfortable disclosing their hearing loss over time (p = 0.009); had not experienced reactions of being treated unfairly or discriminated against (p = 0.021); and were diagnosed with mixed hearing loss (p = 0.004). Nondisclosers tended not to disclose in a group setting (p = 0.002) and were diagnosed with bilateral hearing loss (p = 0.005). In addition, all of the variables were examined to build logistic regression models to predict the use of each disclosure strategy.Conclusions
Our results reveal three simple strategies for verbally addressing hearing loss that can be used in a variety of contexts. We recommend educating people with hearing loss about these strategies-this could improve the experience of disclosing hearing loss, and could educate society at large about how to interact with those who have a hearing loss.Item Open Access The emerging phenotype of long-term survivors with infantile Pompe disease.(Genetics in medicine : official journal of the American College of Medical Genetics, 2012-09) Prater, Sean N; Banugaria, Suhrad G; DeArmey, Stephanie M; Botha, Eleanor G; Stege, Erin M; Case, Laura E; Jones, Harrison N; Phornphutkul, Chanika; Wang, Raymond Y; Young, Sarah P; Kishnani, Priya SPurpose
Enzyme replacement therapy with alglucosidase alfa for infantile Pompe disease has improved survival creating new management challenges. We describe an emerging phenotype in a retrospective review of long-term survivors.Methods
Inclusion criteria included ventilator-free status and age ≤6 months at treatment initiation, and survival to age ≥5 years. Clinical outcome measures included invasive ventilator-free survival and parameters for cardiac, pulmonary, musculoskeletal, gross motor, and ambulatory status; growth; speech, hearing, and swallowing; and gastrointestinal and nutritional status.Results
Eleven of 17 patients met study criteria. All were cross-reactive immunologic material-positive, alive, and invasive ventilator-free at most recent assessment, with a median age of 8.0 years (range: 5.4-12.0 years). All had marked improvements in cardiac parameters. Commonly present were gross motor weakness, motor speech deficits, sensorineural and/or conductive hearing loss, osteopenia, gastroesophageal reflux, and dysphagia with aspiration risk. Seven of 11 patients were independently ambulatory and four required the use of assistive ambulatory devices. All long-term survivors had low or undetectable anti-alglucosidase alfa antibody titers.Conclusion
Long-term survivors exhibited sustained improvements in cardiac parameters and gross motor function. Residual muscle weakness, hearing loss, risk for arrhythmias, hypernasal speech, dysphagia with risk for aspiration, and osteopenia were commonly observed findings.Item Open Access The impact of hearing loss on trajectories of depressive symptoms in married couples.(Social science & medicine (1982), 2023-03) West, Jessica S; Smith, Sherri L; Dupre, Matthew EHearing loss is a prevalent chronic stressor among older adults and is associated with numerous adverse health outcomes. The life course principle of linked lives highlights that an individual's stressors can impact the health and well-being of others; however, there are limited large-scale studies examining hearing loss within marital dyads. Using 11 waves (1998-2018) of the Health and Retirement Study (n = 4881 couples), we estimate age-based mixed models to examine how 1) one's own hearing, 2) one's spouse's hearing, or 3) both spouses' hearing influence changes in depressive symptoms. For men, their wives' hearing loss, their own hearing loss, and both spouses having hearing loss are associated with increased depressive symptoms. For women, their own hearing loss and both spouses having hearing loss are associated with increased depressive symptoms, but their husbands' hearing loss is not. The connections between hearing loss and depressive symptoms within couples are a dynamic process that unfolds differently by gender over time.
