Prevalence, diagnoses and rehabilitation services related to severe dual sensory loss (DSL) in older persons: a cross-sectional study based on medical records.

OBJECTIVE: To estimate the prevalence of severe dual sensory loss (DSL) among older persons (aged ≥65 years) in the Swedish population, to identify the diagnoses that cause severe DSL, and to identify rehabilitation services in which the participants have been involved. DESIGN: A cross-sectional design was applied. Medical records from Audiological, Low Vision, and Vision clinics from two Swedish counties were used. STUDY SAMPLE: 1257 adults, aged ≥65 years with severe hearing loss (HL) (≥70 dB HL) were included, whereof 101 had decimal visual acuity ≤0.3. RESULTS: Based on the population size in the two counties (≥65 years, n = 127,638), the prevalence of severe DSL was approximately 0.08% in the population. Within the group having DSL (n = 101), 61% were women and 71% were aged ≥85 years. Common diagnoses were cataract and/or age-related macular degeneration (AMD) in combination with HL. The rehabilitation services offered were mainly hearing aids and various magnifiers. CONCLUSIONS: The study confirmed previous results, indicating that the prevalence of severe DSL increases with age and that sensorineural HL and cataract, AMD or glaucoma coexist. The identified rehabilitation services mainly focussed on either vision loss or HL but not on severe DSL as a complex health condition.

Headphone listening habits, hearing thresholds and listening levels in Swedish adolescents with severe to profound HL and adolescents with normal hearing.

OBJECTIVE: Research has minimally focussed on the music listening habits and preferred sound volumes among adolescents with severe to profound congenital HL. Listening to music played at loud sound volumes and for a long duration of time could imply risks of worsening the HL. Therefore, it is important to investigate the listening habits in adolescents with HL. The aim of the present study was to describe the use of personal music devices, subjective estimated sound levels, measured sound levels, listening habits, and hearing symptoms in adolescents with severe to profound hearing loss compared with adolescents with normal hearing. DESIGN: The study was conducted in two steps. First, a questionnaire was given to students with or without hearing loss. In step two, hearing and sound level measurements were made in a subsample from both groups. STUDY SAMPLE: The study sample were based on 112 seventeen-year-old students with severe to profound hearing loss and 279 adolescents with normal hearing. Hearing thresholds and listening levels was measured on two subsamples based on 29 adolescents with severe to profound hearing loss and 50 adolescents from the group with normal hearing. RESULTS: The results showed that adolescents with severe to profound hearing loss listened to significantly louder sound levels for longer periods. For both groups, those listening at louder sound levels had poorer hearing thresholds. This finding is especially alarming for subjects with hearing loss. Among those listening above 85 dB per occasion, the sound level ranged between 85.8 dB up to 109 dB for those with hearing loss, whereas the sound level ranged between 85.5 dB and 100 dB for those with normal hearing. CONCLUSIONS: Adolescents with congenital hearing loss used portable music devices in the same manner as adolescents with normal hearing. However, adolescents with hearing loss listened to louder sound volumes most likely to compensate for their hearing loss, which significantly increases the risk of further damage to their hearing. From a hearing rehabilitation perspective it could be concluded that aspect of music listening habits should be focussed in order to prevent noise induced hearing loss among individuals with congenital hearing loss.

Headphone listening habits and hearing thresholds in swedish adolescents.

INTRODUCTION: The aim of this study was to investigate self-reported hearing and portable music listening habits, measured hearing function and music exposure levels in Swedish adolescents. The study was divided into two parts. MATERIALS AND METHODS: The first part included 280 adolescents, who were 17 years of age and focused on self-reported data on subjective hearing problems and listening habits regarding portable music players. From this group, 50 adolescents volunteered to participate in Part II of the study, which focused on audiological measurements and measured listening volume. RESULTS: The results indicated that longer lifetime exposure in years and increased listening frequency were associated with poorer hearing thresholds and more self-reported hearing problems. A tendency was found for listening to louder volumes and poorer hearing thresholds. Women reported more subjective hearing problems compared with men but exhibited better hearing thresholds. In contrast, men reported more use of personal music devices, and they listen at higher volumes. DISCUSSION: Additionally, the study shows that adolescents listening for ≥3 h at every occasion more likely had tinnitus. Those listening at ≥85 dB LAeq, FF and listening every day exhibited poorer mean hearing thresholds, reported more subjective hearing problems and listened more frequently in school and while sleeping. CONCLUSION: Although the vast majority listened at moderate sound levels and for shorter periods of time, the study also indicates that there is a subgroup (10%) that listens between 90 and 100 dB for longer periods of time, even during sleep. This group might be at risk for developing future noise-induced hearing impairments.

Adolescents' reported hearing symptoms and attitudes toward loud music.

The aim of the present study was to compare the adolescents' attitudes toward loud music in relation to a set of self-perceived auditory symptoms and psychological variables such as norms, preparedness to take risks and risk-judgment in noisy situations. A questionnaire on hearing and preventive behavior was distributed to 281 upper secondary school students aged 15-19 years. The questionnaire included youth attitude to noise scale, questions about perceived hearing symptoms such as tinnitus and sound sensitivity and finally statements on perceived behavioral norms regarding hearing protection use, risk-taking and risk-judgment in noisy settings. Self-perceived auditory symptoms such as sound sensitivity and permanent tinnitus had a significant relationship with less tolerant attitudes toward loud music. Permanent tinnitus and sound sensitivity together accounted for 15.9% of the variation in attitudes toward loud music. Together with the psychological variables norms, preparedness to take risks and risk-judgment 48.0% of the variation in attitudes could be explained. Although perceived hearing symptoms (sound sensitivity and permanent tinnitus) was associated with less tolerant attitudes toward loud music, psychological variables such as norms, preparedness to take risks and risk-judgment were found to be more strongly associated with attitudes toward loud music and should therefore be considered more in future preventive work. Health promotive strategies should focus on changing not merely individual attitudes, but also societal norms and regulations in order to decrease noise induced auditory symptoms among adolescents.

Experiences of rehabilitation services from the perspective of older adults with dual sensory loss - a qualitative study.

PURPOSE: To describe the rehabilitation service experiences of older adults with dual sensory loss (DSL). METHODS: Twenty older adults aged ≥65 years with DSL participated in semistructured interviews. Inductive qualitative content analysis was conducted. RESULTS: The participants' experiences were classified into three main categories: 1. Maintaining and regaining function included experiences regarding interventions compensating for loss of function and medical corrections; 2. Mastering the situation described the individuals' competence of DSL, skills acquisition and taking control; and 3. Delivery of rehabilitation services included experiences of encounters with professionals, their attitudes and the organizational impact on accessibility and collaboration. CONCLUSIONS: It was important for participants to regain function and compensate for loss in function and to meet others in group rehabilitation. The professionals' attitudes were an important factor that affected the participants' approach to rehabilitation services. Rehabilitation services mainly focused on either VL or HL, not DSL. Based on the participants' experiences, the rehabilitation services seemed to contribute to the older adults' well-being, participation in activities and life roles, which is consistent with the WHO's definition of healthy ageing. The findings can contribute to the development of rehabilitation services for older adults with DSL to meet the diversity of these individuals' needs.

Perceived hearing status and attitudes toward noise in young adults.

PURPOSE: To estimate the prevalence of perceived hearing loss, tinnitus, and temporary threshold shift (TTS) in community college students and to see whether those students' attitudes toward noise affected their perception of their own possible hearing loss, tinnitus, and TTS. METHOD: Young adults (N = 245; age 18-27) completed 3 questionnaires: the Hearing Symptom Description, Youth Attitude to Noise Scale, and Adolescents' Habits and Hearing Protection Use. RESULTS: Perceived TTS and pain associated with loud noise were the most common hearing related factors, followed by perceived tinnitus and hearing loss. The students' attitudes toward noise in their daily environment showed the most negative response, whereas attitudes toward noise and concentration indicated a more positive, or less harmful, response. Chi-square analysis indicated a significant correlation between perceived hearing loss and respondents' overall attitudes toward noise exposure. Hearing protection use was limited for all participants, with the majority reporting never having used hearing protection. CONCLUSION: Approximately 6% of respondents reported perceived hearing loss, and 13.5% reported prolonged tinnitus. In general, participants had neutral attitudes toward noise. Over 20% of participants reported ear pain, tinnitus, and/or TTS after noise exposure at least sometimes. Coincidentally, few participants reported consistent use of hearing protection.
