Factors Associated With Self-Perceived Hearing Handicap in Adults From Hispanic/Latino Background: Findings From the Hispanic Community Health Study/Study of Latinos.

OBJECTIVES: We sought to determine what factors, including acculturation (language and social contact preferences), were associated with self-perceived hearing handicap among adults from Hispanic/Latino background. We utilized the Aday-Andersen behavioral model of health services utilization to frame our hypotheses that predisposing characteristics (age, sex, education, city of residence, Hispanic/Latino background, and acculturation), enabling resources (annual income and current health insurance coverage), and need (measured hearing loss and self-reported hearing loss) would be related to clinically-significant self-perceived hearing handicap as measured by the Hearing Handicap Inventory - Screening (HHI-S) version. DESIGN: We analyzed baseline data collected from 2008 to 2011 as part of the multisite Hispanic Community Health Study/Study of Latinos. Data were from 6585 adults with hearing loss (defined by a worse-ear 500, 1000, 2000, and 4000 Hz pure-tone average [PTA] of ≥25 dB HL and/or a 4000, 6000, and 8000 Hz high-frequency PTA of ≥25 dB HL) aged 18 to 74 years from various Hispanic/Latino backgrounds. We conducted a series of multivariable logistic regression models examining the roles of independent variables of interest representing predisposing, enabling, and need indicators on the occurrence of clinically-significant self-perceived hearing handicap (e.g., HHI-S score > 8). RESULTS: Among included participants, 953 (14.5%) had an HHI-S score >8. The final model revealed significant associations between predisposing characteristics, enabling resources, need, and HHI-S outcome. Predisposing characteristics and need factors were associated with higher odds of reporting self-perceived hearing handicap (HHI-S score >8) including acculturation as measured by the Short Acculturation Scale for Hispanics (odds ratio [OR] = 1.28, 95% confidence interval [CI]: 1.09-1.50), female sex (OR = 1.72, 95% CI: 1.27-2.33), and poorer worse ear 500, 1000, 2000, and 4000 Hz PTA (OR = 1.02, 95% CI: 1.01-1.03); suggesting that a 5-decibel increase in a person's PTA was consistent with 10% higher odds of a HHI-S score of >8. Greater enabling resources were associated with lower odds of reporting clinically-significant self-perceived hearing handicap: compared with individuals with income <$10,000/year, the multivariable-adjusted OR among individuals with income $40,000 to $7500/year was 0.55 (95% CI: 0.33-0.89) and among individuals with income >$75,000/year was 0.28 (95% CI: 0.13-0.59]; p-trend < 0.0001). CONCLUSIONS: Our findings suggest there are associations between predisposing, enabling and need variables consistent with the Aday-Andersen model and self-perceived hearing handicap among adults from Hispanic/Latino background. The influence of language and culture on perceived hearing loss and associated handicap is complex, and deserves more attention in future studies. Our findings warrant further investigation into understanding the role of language and language access in hearing health care utilization and outcomes, as the current body of literature is small and shows mixed outcomes.

RISK FACTORS FOR HEARING IMPAIRMENT IN TYPE 1 DIABETES.

Objective: Studies have demonstrated that glycated hemoglobin (HbA1c) is a significant predictor of hearing impairment in type 1 diabetes. We identified additional factors associated with hearing impairment in participants with type 1 diabetes from the Diabetes Control and Complications Trial and its observational follow-up, the Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. Methods: A total of 1,150 DCCT/EDIC participants were recruited for the Hearing Study. A medical history, physical measurements, and a self-administered hearing questionnaire were obtained. Audiometry was performed by study-certified personnel and assessed centrally. Logistic regression models assessed the association of risk factors and comorbidities with speech- and high-frequency hearing impairment. Results: Mean age was 55 ± 7 years, duration of diabetes 34 ± 5 years, and DCCT/EDIC HbA1c 7.9 ± 0.9% (63 mmol/mol). In multivariable models, higher odds of speech-frequency impairment were significantly associated with older age, higher HbA1c, history of noise exposure, male sex, and higher triglycerides. Higher odds of high-frequency impairment were associated with older age, male sex, history of noise exposure, higher skin intrinsic florescence (SIF) as a marker of tissue glycation, higher HbA1c, nonprofessional/nontechnical occupations, sedentary activity, and lower low-density-lipoprotein cholesterol. Among participants who previously completed computed tomography and carotid ultrasonography, coronary artery calcification (CAC) >0 and carotid intima-medial thickness were significantly associated with high-but not speech-frequency impairment. Conclusion: Consistent with previous reports, male sex, age, several metabolic factors, and noise exposure are independently associated with hearing impairment. The association with SIF further emphasizes the importance of glycemia-as a modifiable risk factor-over time. In addition, the macrovascular contribution of CAC is novel and important.

Prevalence and Risk Factors of Self-Reported Smell and Taste Alterations: Results from the 2011-2012 US National Health and Nutrition Examination Survey (NHANES).

Chemosensory problems challenge health through diminished ability to detect warning odors, consume a healthy diet, and maintain quality of life. We examined the prevalence and associated risk factors of self-reported chemosensory alterations in 3603 community-dwelling adults (aged 40+ years), from the nationally representative, US National Health and Nutrition Examination Survey (NHANES) 2011-2012. In this new NHANES component, technicians surveyed adults in the home about perceived smell and taste problems, distortions, and diminished abilities since age 25 (termed "alterations"), and chemosensory-related health risks and behaviors. The prevalence of self-reported smell alteration was 23%, including phantosmia at 6%; taste was 19%, including dysgeusia at 5%. Prevalence rates increased progressively with age, highest in those aged 80+ years (smell, 32%; taste, 27%). In multivariable logistic regression, controlling for sociodemographics, health behaviors, and chemosensory-related conditions, the strongest independent risk factor for smell alteration was sinonasal symptoms (odds ratio [OR] = 2.06; 95% confidence interval [CI]: 1.63-2.61), followed by heavy drinking, loss of consciousness from head injury, family income ≤110% poverty threshold, and xerostomia. For taste, the strongest risk factor was xerostomia (OR = 2.65; 95% CI: 1.97-3.56), followed by nose/facial injury, lower educational attainment, and fair/poor health. Self-reported chemosensory alterations are prevalent in US adults, supporting increased attention to decreasing their modifiable risks, managing safety/health consequences, and expanding chemosensory screening/testing and treatments.

Hearing loss in an aging American population: extent, impact, and management.

Despite contributing substantially to disability in the United States, age-related hearing loss is an underappreciated public health concern. Loss of hearing sensitivity has been documented in two-thirds of adults aged 70 years and older and has been associated with communication difficulties, lower health-related quality of life, and decreased physical and cognitive function. Management strategies for age-related hearing loss are costly, yet the indirect costs due to lost productivity among people with communication difficulties are also substantial and likely to grow. Hearing aids can improve health-related quality of life, but the majority of people with documented hearing loss do not report using them. Uncovering effective means to improve the utilization of hearing health care services is essential for meeting the hearing health care demands of our aging population. The importance of hearing for general well-being warrants an effort to enhance awareness among the general population of the indications of hearing loss and options for assistance.

Hearing aid use among older U.S. adults; the national health and nutrition examination survey, 2005-2006 and 2009-2010.

OBJECTIVES: The authors estimated the proportion of older adults in the United States who report hearing aid use among those likely to benefit. To more fully understand what factors underlie the low proportion of hearing aid use, the authors examined a variety of socio-demographic correlates as well as measures of health care access and insurance status in relation to hearing aid use among potential hearing aid candidates. DESIGN: The study makes use of cross-sectional data collected during 2005-2006 and 2009-2010 as part of the National Health and Nutrition Examination Survey. The 1636 adults aged 70 years and older were selected by using a complex sampling design and comprise a nationally representative sample. In addition to self-reported hearing aid use, data on pure-tone thresholds, perceived hearing ability, place for routine health care, time since last hearing test, type of insurance coverage, and socio-demographic characteristics including age, sex, race/ethnicity, family size, and income-to-poverty ratio were collected. The analytical sample consisted of 601 adults who had a better-ear pure-tone average of ≥35 dB HL at 500, 1000, and 2000 Hz or who reported moderate or worse hearing ability. RESULTS: One third of the potential hearing aid candidates reported current use of hearing aids. The authors observed a 28 to 66% greater prevalence of hearing aid use among older adults in the upper four fifths of the income-to-poverty distribution compared with those in the bottom one fifth. Compared with people who had their hearing tested 5 to 9 years ago, those with more recent hearing tests were more than two to three times as likely to be a current hearing aid user. No differences were observed by age after adjusting for pure-tone average and no differences were observed by sex after adjusting for perceived hearing ability. No differences were observed by place of routine health care or by type of insurance coverage. CONCLUSIONS: Use of hearing aids is low among older adults who might benefit. Identifying and surmounting barriers to hearing aid use, especially among low-income adults, remains an important objective for hearing health care in the United States.

Priorities for hearing loss prevention and estimates of global cause-specific burdens of hearing loss: a systematic rapid review.

BACKGROUND: Hearing loss affects approximately 1·6 billion individuals worldwide. Many cases are preventable. We aimed to estimate the annual number of new hearing loss cases that could be attributed to meningitis, otitis media, congenital rubella syndrome, cytomegalovirus, and ototoxic medications, specifically aminoglycosides, platinum-based chemotherapeutics, and antimalarials. METHODS: We used a targeted and a rapid systematic literature review to calculate yearly global incidences of each cause of hearing loss. We estimated the prevalence of hearing loss for each presumed cause. For each cause, we calculated the global number of yearly hearing loss cases associated with the exposure by multiplying the estimated exposed population by the prevalence of hearing loss associated with the exposure, accounting for mortality when warranted. FINDINGS: An estimated 257·3 million people per year are exposed to these preventable causes of hearing loss, leading to an estimated 33·8 million new cases of hearing loss worldwide per year. Most hearing loss cases were among those with exposure to ototoxic medications (19·6 million [range 12·6 million-27·9 million] from short-course aminoglycoside therapy and 12·3 million from antimalarials). We estimated that 818 000 cases of hearing loss were caused by otitis media, 346 000 by meningitis, 114 000 by cytomegalovirus, and 59 000 by congenital rubella syndrome. INTERPRETATION: The global burden of preventable hearing loss is large. Hearing loss that is attributable to disease sequelae or ototoxic medications contributes substantially to the global burden of hearing loss. Prevention of these conditions should be a global health priority. FUNDING: The US National Institute on Deafness and Other Communication Disorders and the US National Institute on Aging.

Hearing Sensitivity, Cardiovascular Risk, and Neurocognitive Function: The Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

Importance: Both cardiovascular disease risk and hearing impairment are associated with cognitive dysfunction. However, the combined influence of the 2 risk factors on cognition is not well characterized. Objective: To examine associations between hearing impairment, cardiovascular disease risk, and cognitive function. Design, Setting, and Participants: This population-based, prospective cohort, multisite cross-sectional analysis of baseline data collected between 2008 and 2011 as part of the Hispanic Community Health Study/Study of Latinos included 9623 Hispanic or Latino adults aged 45 to 74 years in New York, Chicago, Miami, and San Diego. Exposures: Hearing impairment of at least mild severity was defined as the pure tone average of 500, 1000, 2000, and 4000 Hz greater than 25 dB hearing level (dB HL) in the better ear. Our measure of cardiovascular disease risk was a latent class variable derived from body mass index, ankle-brachial index, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, fasting blood glucose, and the Framingham Cardiovascular Risk score. Main Outcomes and Measures: Results on Brief-Spanish English Verbal Learning Test (episodic learning and memory), and Word Fluency (verbal fluency), and Digit Symbol Subtest (processing speed/executive functioning), and a cognitive composite of the mentioned tests (overall cognition). Results: Participants (N = 9180) were 54.4% female and age 56.5 years on average. Hearing impairment was associated with poorer performance on all cognitive measures (global cognition: unstandardized ß, -0.11; 95% CI, -0.16 to 0.07). Cardiovascular grouping (healthy, typical, high cardiovascular disease risk, and hyperglycemia) did not attenuate the associations between hearing impairment and cognition (global cognition: unstandardized ß, -0.11; 95% CI, -0.15 to -0.06). However, cardiovascular grouping interacted with hearing impairment such that hyperglycemia in the context of hearing impairment exacerbated poor performance on learning and memory tasks (F3 = 3.70 and F3 = 2.92, respectively). Conclusions and Relevance: The findings of this cohort study suggest that hearing impairment increases the likelihood that individuals with excessively high glucose perform poorly on learning and memory tasks. Further research is needed to specify the mechanisms by which cardiovascular disease risk and hearing impairment are collectively associated with cognition.

Phantom odor perception and vascular conditions among adults in the United States: National Health and Nutrition Examination Survey 2011-2014.

OBJECTIVES/HYPOTHESIS: Phantom odor perception has been correlated with burden of vascular risk among older adults. We evaluated associations between vascular conditions and phantom odor perception among adults in the United States. STUDY DESIGN: Cross-sectional analysis. METHODS: Cross-sectional data were collected as part of the 2011 to 2014 National Health and Nutrition Examination Survey, yielding a nationally representative sample of 7,417 adults aged 40 years and older. Phantom odor perception was defined as report of an unpleasant, bad, or burning odor when nothing is there. Participants reported on vascular conditions including history of stroke. Total cholesterol and glycated hemoglobinwere measured. High blood pressure was ascertained during an examination. RESULTS: Stroke was associated with a 76% greater likelihood of phantom odor perception. Congestive heart failure and angina were associated with three times and 2.8 times the odds of phantom odor perception among adults 40 to 59 years and 60 years and older, respectively. Adults with diagnosed, but controlled, high cholesterol reported phantom odors more frequently than those without high cholesterol. Adults with diagnosed, but controlled, high blood pressure reported phantom odors more frequently than those without high blood pressure. We observed a threefold greater odds of phantom odor perception among adults aged 60 years and older with diabetes, but only among those who use both insulin and oral medications. CONCLUSIONS: Stroke, angina, congestive heart failure, well-managed high blood pressure, and well-managed high cholesterol are associated with phantom odor perception. Vascular or metabolic conditions or their treatments may contribute to reporting of phantom odor perception. LEVEL OF EVIDENCE: NA Laryngoscope, 130:332-337, 2020.

Prescription Medication Use and Phantom Odor Perception Among US Adults.

INTRODUCTION: Prescription medication use may be associated with phantom odor perception. We evaluated associations between number of prescription medications and their therapeutic class and phantom odor perception among U.S. adults. METHODS: Data were collected between 2011-2014 as part of the National Health and Nutrition Examination Survey (NHANES). A complex sampling design resulted in a nationally representative sample of 7,417 adults aged 40 years and older. During an in-home interview, participants were asked whether they had experienced an unpleasant, bad, or burning odor when nothing is there. Prescription medication use was assessed using validation with prescription bottles, when possible. RESULTS: Almost one quarter (23.3%) of adults uses ≥5 prescription medications. Use of five or more prescription medications is associated with 70% greater odds of phantom odor perception (OR 1.69 (1.09, 2.63)). Among adults 60 years and older, antidiabetic medications, antihyperlipidemic agents, and proton pump inhibitors are associated with 74-88% greater odds of report of phantom odor [OR=1.74 (1.09, 2.77), OR=1.85 (1.22. 2.80), and OR=1.88 (1.15, 3.07)], respectively. CONCLUSIONS: Phantom odor perception may be a side effect of antidiabetic or antihyperlipidemic agents. Among people taking proton pump inhibitors, phantom odors may also be a consequence of gastric gas reflux. IMPLICATIONS: Common prescription medications may be providing an olfactory stimulus.

Diabetes and hearing impairment in the United States: audiometric evidence from the National Health and Nutrition Examination Survey, 1999 to 2004.

BACKGROUND: Diabetes might affect the vasculature and neural system of the inner ear, leading to hearing impairment. OBJECTIVE: To determine whether hearing impairment is more prevalent among U.S. adults with diabetes. DESIGN: Cross-sectional analysis of nationally representative data. SETTING: National Health and Nutrition Examination Survey, 1999 to 2004. PARTICIPANTS: 5140 noninstitutionalized adults age 20 to 69 years who had audiometric testing. MEASUREMENTS: Hearing impairment was assessed from the pure tone average of thresholds over low or mid-frequencies (500, 1000, and 2000 Hz) and high frequencies (3000, 4000, 6000, and 8000 Hz) and was defined as mild or greater severity (pure tone average >25 decibels hearing level [dB HL]) and moderate or greater severity (pure tone average >40 dB HL). RESULTS: Hearing impairment was more prevalent among adults with diabetes. Age-adjusted prevalence of low- or mid-frequency hearing impairment of mild or greater severity in the worse ear was 21.3% (95% CI, 15.0% to 27.5%) among 399 adults with diabetes compared with 9.4% (CI, 8.2% to 10.5%) among 4741 adults without diabetes. Similarly, age-adjusted prevalence of high-frequency hearing impairment of mild or greater severity in the worse ear was 54.1% (CI, 45.9% to 62.3%) among those with diabetes compared with 32.0% (CI, 30.5% to 33.5%) among those without diabetes. The association between diabetes and hearing impairment was independent of known risk factors for hearing impairment, such as noise exposure, ototoxic medication use, and smoking (adjusted odds ratios for low- or mid-frequency and high-frequency hearing impairment were 1.82 [CI, 1.27 to 2.60] and 2.16 [CI, 1.47 to 3.18], respectively). LIMITATIONS: The diagnosis of diabetes was based on self-report. The investigators could not distinguish between type 1 and type 2 diabetes. Noise exposure was based on participant recall. CONCLUSION: Hearing impairment is common in adults with diabetes, and diabetes seems to be an independent risk factor for the condition.

Hearing Aid Prevalence and Factors Related to Use Among Older Adults From the Hispanic Community Health Study/Study of Latinos.

Importance: Hearing loss is highly prevalent in the rapidly growing and aging Hispanic/Latino population in the United States. However, little is known or understood about hearing aid use among US adults from Hispanic/Latino backgrounds. Objective: To describe hearing aid prevalence and factors associated with hearing aid use among US adults of Hispanic/Latino backgrounds. Design, Setting, and Participants: Cross-sectional data were collected between 2008 and 2011 from 4 field centers (Bronx, New York; Chicago, Illinois; Miami, Florida; and San Diego, California) as part of the multisite Hispanic Community Health Study/Study of Latinos. Included individuals were adults aged 45 to 76 years with hearing loss (pure-tone average ≥25 dB HL) from randomly selected households in the 4 field centers and were from self-reported Hispanic/Latino backgrounds, including Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and mixed or other backgrounds. Analysis, including age- and background-weighted prevalence estimates and multivariate logistic regression using survey methodology, was conducted from 2017 to 2018. Main Outcomes and Measures: The primary outcome of interest was self-reported hearing aid use. The a priori hypothesis was that hearing aid prevalence estimates among included Hispanic/Latino adults would be less than recently published estimates of the general US population, and that poorer hearing, higher perceived need, older age, and higher acculturation would be associated with hearing aid use. Results: Of 1898 individuals with hearing loss, 1064 (56.1%) were men, and the mean (SE) age was 60.3 (0.3) years. A total of 87 (4.6%) included individuals reported hearing aid use. Increased odds of self-reported use was associated with poorer measured hearing (odds ratio [OR], 1.06; 95% CI, 1.03-1.09), higher Hearing Handicap Inventory-Screening scores (OR, 1.06; 95% CI, 1.03-1.08), access to health insurance coverage (OR, 2.30; 95% CI, 1.20-4.37), and place of residence (OR, 2.42; 95% CI, 1.17-5.02) in an adjusted logistic regression model. Conclusions and Relevance: Findings revealed underuse of hearing aids among adults from Hispanic/Latino backgrounds. A primary factor related to use was lack of health insurance, which suggests that access influenced hearing aid use. Changes to policy and clinical service provision are needed to increase hearing aid use among aging Hispanic/Latino adults in the United States.

Factors Associated With Phantom Odor Perception Among US Adults: Findings From the National Health and Nutrition Examination Survey.

Importance: Phantom odor perception can be a debilitating condition. Factors associated with phantom odor perception have not been reported using population-based epidemiologic data. Objective: To estimate the prevalence of phantom odor perception among US adults 40 years and older and identify factors associated with this condition. Design, Setting, and Participants: In this cross-sectional study with complex sampling design, 7417 adults 40 years and older made up a nationally representative sample from data collected in 2011 through 2014 as part of the National Health and Nutrition Examination Survey. Exposures: Sociodemographic characteristics, cigarette and alcohol use, head injury, persistent dry mouth, smell function, and general health status. Main Outcomes and Measures: Phantom odor perception ascertained as report of unpleasant, bad, or burning odor when no actual odor exists. Results: Of the 7417 participants in the study, 52.8% (3862) were women, the mean (SD) age was 58 (12) years, and the prevalence of phantom odor perception occurred in 534 participants, which was 6.5% of the population (95% CI, 5.7%-7.5%). Phantom odor prevalence varied considerably by age and sex. Women 60 years and older reported phantom odors less commonly (7.5% [n = 935] and 5.5% [n = 937] among women aged 60-69 years and 70 years and older, respectively) than younger women (9.6% [n = 1028] and 10.1% [n = 962] among those aged 40-49 years and 50-59 years, respectively). The prevalence among men varied from 2.5% (n = 846) among men 70 years and older to 5.3% (n = 913) among men 60 to 69 years old. Phantom odor perception was 60% (n = 1602) to 65% (n = 2521) more likely among those with an income-to-poverty ratio of less than 3 compared with those in the highest income-to-poverty ratio group (odds ratio [OR], 1.65; 95% CI, 1.06-2.56; and OR, 1.60; 95% CI, 1.01-2.54 for income-to-poverty ratio <1.5 and 1.5-2.9, respectively). Health conditions associated with phantom odor perception included persistent dry mouth (OR, 3.03; 95% CI, 2.17-4.24) and history of head injury (OR, 1.74; 95% CI, 1.20-2.51). Conclusions and Relevance: An age-related decline in the prevalence of phantom odor perception is observed in women but not in men. Only 11% (n = 64) of people who report phantom odor perception have discussed a taste or smell problem with a clinician. Associations of phantom odor perception with poorer health and persistent dry mouth point to medication use as a potential explanation. Prevention of serious head injuries could have the added benefit of reducing phantom odor perception.

Hearing Impairment and Type 1 Diabetes in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) Cohort.

OBJECTIVE: To evaluate the prevalence of hearing impairment in participants with type 1 diabetes enrolled in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study and compare with that of a spousal control group without diabetes. Among participants with type 1 diabetes, to evaluate the association of hearing impairment with prior DCCT therapy and overall glycemia. RESEARCH DESIGN AND METHODS: DCCT/EDIC participants (n = 1,150) and 288 spouses without diabetes were recruited for the DCCT/EDIC Hearing Study. All subjects completed a self-administered questionnaire, medical history, and physical measurements. Audiometry was performed by study-certified personnel; audiograms were assessed centrally. Speech-frequency (pure-tone average [PTA] thresholds at 500, 1,000, 2,000, and 4,000 Hz) and high-frequency impairment (PTA thresholds at 3,000, 4,000, 6,000, and 8,000 Hz) were defined as PTA >25 dB hearing loss. Logistic regression models were adjusted for age and sex. RESULTS: DCCT/EDIC participants and spousal control subjects were similar in age, race, education, smoking, and systolic blood pressure. There were no statistically significant differences between groups in the prevalence or adjusted odds of speech- or high-frequency impairment in either ear. Among participants with type 1 diabetes, for every 10% increase in the time-weighted mean HbA1c, there was a 32% (95% CI 1.15-1.50) and 19% (95% CI 1.07-1.33) increase in speech- and high-frequency hearing impairment, respectively. CONCLUSIONS: We found no significant difference in the prevalence of hearing impairment between the group with type 1 diabetes and the spousal control group. Among those with type 1 diabetes, higher mean HbA1c over time was associated with hearing impairment.

Voice disorders and associated risk markers among young adults in the United States.

OBJECTIVES/HYPOTHESIS: To examine the prevalence of voice disorders in young adults and identify sociodemographic factors, health conditions, and behaviors associated with voice disorder prevalence. STUDY DESIGN: Cross-sectional analysis of data from the National Longitudinal Study of Adolescent to Adult Health. METHODS: During home interviews, 14,794 young adults, aged 24 to 34 years, reported their health conditions and behaviors. Presence and duration of voice disorders were reported over the past 12 months. We computed overall and stratified prevalence estimates by age, gender, race/ethnicity, medical conditions, smoking, and alcohol use. Multiple logistic regression was used to identify independent risk factors for a voice disorder while accounting for the complex sample design. RESULTS: Six percent of participants reported a voice disorder lasting at least 3 days. Females had 56% greater odds of voice disorders than males. Number of days drinking alcohol was associated with voice disorders, but number of smoking days was not. Conditions that increased the likelihood of voice disorders included hypertension (OR = 1.42 [95% confidence interval {CI}: 1.07-1.89]), tinnitus (OR = 1.53 [95% CI: 1.06-2.20]), and anxiety/panic disorder (OR = 1.26 [95% CI: 1.00-1.60]). Results were independent of gender, alcohol consumption, upper respiratory symptoms, and lower respiratory conditions including asthma, bronchitis/emphysema, and gastrointestinal symptoms (diarrhea/nausea/vomiting). CONCLUSIONS: Voice disorders in young adulthood were associated with hypertension, tinnitus, and anxiety. Greater awareness of these relationships may facilitate voice evaluation among people who seek healthcare for these chronic conditions. LEVEL OF EVIDENCE: 2b Laryngoscope, 127:2093-2099, 2017.

Risk Factors for Hearing Impairment among Adults with Diabetes: The Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

AIM: The aim was to examine risk factors for hearing impairment among Hispanic/Latino adults with diabetes. METHODS: Findings are based on 3384 participants aged 18-76 years with diagnosed or previously undetected diabetes who completed audiometric testing as part of the Hispanic Community Health Study/Study of Latinos. We defined hearing impairment as the pure-tone average (PTA) >25 decibels hearing level [dB HL] of pure-tone thresholds at high frequencies (3000, 4000, 6000, and 8000 Hz) in the worse ear and defined a second hearing impairment outcome with the additional requirement of PTA >25 dB HL of low/mid-frequency (500, 1000, and 2000 Hz) thresholds in the worse ear. We identified independent associations using logistic regression. RESULTS: Controlling for age and Hispanic/Latino background, prevalence ratios for hearing impairment in the high plus low/mid frequencies were 1.35 (95% CI 1.07, 1.71) for current smoking, 1.64 (1.14, 2.38) for alcohol consumption (≥ 14 drinks/week for men or ≥ 7 drinks/week for women), and 1.29 (1.06, 1.56) for triglycerides ≥ 150 mg/dL. For high-frequency only hearing impairment, the prevalence ratio for estimated glomerular filtration rate 30-59 mL/min/1.73m2 was 1.23 (1.03, 1.47) adjusted for age and sex. People with family income less than $20,000 had almost twice the prevalence of hearing impairment (PR=1.93 (1.34, 2.78)) as people with income over $40,000. CONCLUSIONS: Current smoking, alcohol consumption, high triglycerides, and chronic kidney disease are potentially preventable correlates of hearing impairment for persons with diabetes. Low income is a marker of increased likelihood of hearing impairment.

Panel 1: Epidemiology, natural history, and risk factors.

BACKGROUND: The First International Symposium on Recent Advances in Otitis Media (OM) with Effusion was held in Columbus, Ohio, in 1975. The symposium has been organized in the United States every 4 years since, followed by a research conference to (a) assess major research accomplishments, (b) identify important research questions and opportunities, (c) develop consensus on definitions and terminology, and (d) establish priorities with short- and long-term research goals. One of the principal areas reviewed quadrennially is Epidemiology, Natural History, and Risk Factors. OBJECTIVE: To provide a review of recent literature on the epidemiology, natural history, and risk factors for OM. DATA SOURCES AND REVIEW METHODS: A search of OM articles in English published July 2007 to June 2011 was conducted using PubMed and related databases. Those with findings judged of importance for epidemiology, public health, and/or statistical methods were reviewed. RESULTS: The literature has continued to expand, increasing understanding of the worldwide burden of OM in childhood, complications from treatment failures, and comorbidities. Novel risk factors, including genetic factors, have been examined for OM susceptibility. Population-based studies in Canada, the United States, and other countries confirmed reductions in OM prevalence. Although most studies concentrated on acute OM (AOM) or OM with effusion (OME), a few examined severe chronic suppurative OM (CSOM), a major public health problem in developing countries and for certain indigenous populations around the world. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Recent publications have reinforced earlier epidemiological findings, while extending our knowledge in human population groups with high burden of OM.

Diabetes knowledge and its relationship with achieving treatment recommendations in a national sample of people with type 2 diabetes.

OBJECTIVE: We examined the prevalence of knowledge of A1C, blood pressure, and LDL cholesterol (ABC) levels and goals among people with diabetes, its variation by patient characteristics, and whether knowledge was associated with achieving levels of ABC control recommended for the general diabetic population. RESEARCH DESIGN AND METHODS: Data came from 1,233 adults who self-reported diabetes in the 2005-2008 National Health and Nutrition Examination Survey. Participants reported their last ABC level and goals specified by their physician (not validated by medical record data). Analysis included descriptive statistics and logistic regression. RESULTS: Among participants tested in the past year, 48% stated their last A1C level. Overall, 63% stated their last blood pressure level and 22% stated their last LDL cholesterol level. Knowledge of ABC levels was greatest in non-Hispanic whites, lowest in Mexican Americans, and higher with more education and income (all P ≤ 0.02). Demographic associations were similar for those reporting physician-specified ABC goals at the American Diabetes Association-recommended levels (A1C <7%, blood pressure <130/80 mmHg, and LDL cholesterol <100 mg/dL). Nineteen percent of participants stated that their provider did not specify an A1C goal compared with 47% and 41% for blood pressure and LDL cholesterol goals, respectively. For people who self-reported A1C <7.0%, 83% had an actual A1C <7.0%. Otherwise, participant knowledge was not significantly associated with risk factor control, except for in those who knew their last LDL cholesterol level (P = 0.046 for A1C <7.0%). Results from logistic regression corroborated these findings. CONCLUSIONS: Ample opportunity exists to improve ABC knowledge. Diabetes education should include behavior change components in addition to information on ABC clinical measures.

Risk factors for hearing impairment among U.S. adults with diabetes: National Health and Nutrition Examination Survey 1999-2004.

OBJECTIVE: The objective of this study was to examine the risk factors of low/mid-frequency and high-frequency hearing impairment among a nationally representative sample of diabetic adults. RESEARCH DESIGN AND METHODS: Data came from 536 participants, aged 20-69 years, with diagnosed or undiagnosed diabetes who completed audiometric testing during 1999-2004 in the National Health and Nutrition Examination Survey (NHANES). We defined hearing impairment as the pure-tone average>25 dB hearing level of pure-tone thresholds at low/mid-frequencies (500; 1,000; and 2,000 Hz) and high frequencies (3,000; 4,000; 6,000; and 8,000 Hz) and identified independent risk factors using logistic regression. RESULTS: Controlling for age, race/ethnicity, and marital status, odds ratios for associations with low/mid-frequency hearing impairment were 2.20 (95% CI 1.28-3.79) for HDL<40 mg/dL and 3.55 (1.57-8.03) for poor health. Controlling for age, race/ethnicity, sex, and income-to-poverty ratio, odds ratios for associations with high-frequency hearing impairment were 4.39 (1.26-15.26) for history of coronary heart disease and 4.42 (1.26-15.45) for peripheral neuropathy. CONCLUSIONS: Low HDL, coronary heart disease, peripheral neuropathy, and having poor health are potentially preventable correlates of hearing impairment for people with diabetes. Glycemic control, years since diagnosis, and type of glycemic medication were not associated with hearing impairment.

Potential mediators of diabetes-related hearing impairment in the U.S. population: National Health and Nutrition Examination Survey 1999-2004.

OBJECTIVE: We examined potential mediators of the reported association between diabetes and hearing impairment. RESEARCH DESIGN AND METHODS: Data come from 1,508 participants, aged 40-69 years, who completed audiometric testing during 1999-2004 in the National Health and Nutrition Examination Survey (NHANES). We defined hearing impairment as the pure-tone average >25 decibels hearing level of pure-tone thresholds at low/mid (500, 1,000, and 2,000 Hz) and high (3,000, 4,000, 6,000, and 8,000 Hz) frequencies. Using logistic regression, we examined whether controlling for vascular or neuropathic conditions, cardiovascular risk factors, glycemia, or inflammation diminished the association between diabetes and hearing impairment. RESULTS: Diabetes was associated with a 100% increased odds of low/mid-frequency hearing impairment (odds ratio 2.03 [95% CI 1.32-3.10]) and a 67% increased odds of high-frequency hearing impairment (1.67 [1.14-2.44]) in preliminary models after controlling for age, sex, race/ethnicity, education, smoking, and occupational noise exposure. Adjusting for peripheral neuropathy attenuated the association with low/mid-frequency hearing impairment (1.70 [1.02-2.82]). Adjusting for albuminuria and C-reactive protein attenuated the association with high-frequency hearing impairment (1.54 [1.02-2.32] and 1.50 [1.01-2.23], respectively). Diabetes was not associated with high-frequency hearing impairment after controlling for A1C (1.09 [0.60-1.99]) but remained associated with low/mid-frequency impairment. We found no evidence suggesting that our observed relationship between diabetes and hearing impairment is due to hypertension or dyslipidemia. CONCLUSIONS: Mechanisms related to neuropathic or microvascular factors, inflammation, or hyperglycemia may be mediating the association of diabetes and hearing impairment.

Prevalence of diabetes and high risk for diabetes using A1C criteria in the U.S. population in 1988-2006.

OBJECTIVE We examined prevalences of previously diagnosed diabetes and undiagnosed diabetes and high risk for diabetes using recently suggested A1C criteria in the U.S. during 2003-2006. We compared these prevalences to those in earlier surveys and those using glucose criteria. RESEARCH DESIGN AND METHODS In 2003-2006, the National Health and Nutrition Examination Survey included a probability sample of 14,611 individuals aged > or =12 years. Participants were classified on glycemic status by interview for diagnosed diabetes and by A1C, fasting, and 2-h glucose challenge values measured in subsamples. RESULTS Using A1C criteria, the crude prevalence of total diabetes in adults aged > or =20 years was 9.6% (20.4 million), of which 19.0% was undiagnosed (7.8% diagnosed, 1.8% undiagnosed using A1C > or =6.5%). Another 3.5% of adults (7.4 million) were at high risk for diabetes (A1C 6.0 to <6.5%). Prevalences were disproportionately high in the elderly. Age-/sex-standardized prevalence was more than two times higher in non-Hispanic blacks and Mexican Americans versus non-Hispanic whites for diagnosed, undiagnosed, and total diabetes (P < 0.003); standardized prevalence at high risk for diabetes was more than two times higher in non-Hispanic blacks versus non-Hispanic whites and Mexican Americans (P < 0.00001). Since 1988-1994, diagnosed diabetes generally increased, while the percent of diabetes that was undiagnosed and the percent at high risk of diabetes generally decreased. Using A1C criteria, prevalences of undiagnosed diabetes and high risk of diabetes were one-third that and one-tenth that, respectively, using glucose criteria. CONCLUSIONS Although A1C detects much lower prevalences than glucose criteria, hyperglycemic conditions remain high in the U.S., and elderly and minority groups are disproportionately affected.
