Objective: To assess the cost-effectiveness of hearing aid interventions to middle-aged and older adults in rural China., Study Design: Randomized controlled trial., Setting: Community centers., Patients: A total of 385 subjects 45 years and older with moderate or above hearing loss participated in the trial, of which 150 were in the treatment group and 235 in the control group., Intervention: Participants were randomly assigned to the treatment group prescribing with hearing aids or to the control group with no intervention., Main Outcome and Measures: The incremental cost-effectiveness ratio was calculated by comparing the treatment group with the control group., Results: Assuming that the average life span of hearing aids is N years, the cost of the hearing aid intervention included the annual purchase cost of 10,000/N yuan, the annual maintenance cost of 41.48 yuan. However, the intervention led to annual healthcare costs of 243.34 yuan saved. The effectiveness of wearing a hearing aid included an increase of 0.017 quality-adjusted life years. It can be calculated that if N > 6.87, the intervention is very cost-effective; if 2.52 < N < 6.87, the increased cost-effectiveness of the intervention is acceptable; if N < 2.52, the intervention is not cost-effective., Conclusion: In general, the average life span of hearing aids is between 3 and 7 years, so hearing aid interventions can be considered cost-effective with high probability. Our results can provide critical reference for policy makers to increase accessibility and affordability of hearing aids., Competing Interests: Conflicts of interest: The authors disclose no conflicts of interest., (Copyright © 2023, Otology & Neurotology, Inc.)

Aims: Hearing impairment (HI) is prevalent among middle-aged and older adults, but few studies have examined its mental health consequences in China. This study investigated the association of HI with depressive symptoms and whether family financial support moderated the association among adults aged 45 in China., Methods: Data were obtained from three waves of the China Health and Retirement Longitudinal Study (2011, 2013 and 2015). Hearing impairment was defined as a self-reported hearing problem in one or both ears. Depressive symptoms were measured with CESD-10. Associations between HI and depressive symptoms were modeled using fixed-effect models., Results: People with self-reported hearing loss were more likely than those without hearing loss to have depressive symptoms, with an odds ratio of 1.25 [1.07-1.47]. The association remained significant after adjusting for socio-demographic characteristics, lifestyle behaviors, and health conditions. Family financial support moderated this association. Among those with HI, adults with a higher level of family financial support tend to have better performance on symptoms of depression., Conclusions: HI was positively associated with depressive symptoms among adults aged ≥45 in China, and family financial support played a buffering role in the relationship between HI and depressive symptoms., (© 2022 John Wiley & Sons Ltd.)

Background: Hearing loss has been associated with serious health problems around the globe. Previous studies have found the positive effects of fitting hearing aids on health, but few studies were conducted in developing countries. The aim of this study is to examine the effects of hearing aids on multiple health outcomes among middle-aged and older adults with hearing loss in rural China., Methods: In this randomized controlled trial (RCT), participants aged 45 and above were randomly assigned to the treatment group prescribing with hearing aids or to the control group with no intervention. Trial outcomes for 385 participants were collected during the 20-month follow-up study. Using the difference-in-difference approach, our primary outcomes were hearing-related quality of life (QoL) and generic QoL., Results: The intervention led to improvements in hearing-related QoL, presenting as the reduction in Hearing Handicap Inventory for the Elderly Screening Version (HHIE-S) scores (interaction coefficient = - 2.86, p = 0.005), HHIE-S-Emotional scores (interaction coefficient = - 1.42, p = 0.029), and HHIE-S-Situational scores (interaction coefficient = - 1.43, p = 0.007). The intervention was also effective in alleviating the increase in depressive symptoms (interaction coefficient = - 0.14, p = 0.042). Subgroup analysis revealed that the effects were only shown among people with social activities or active social networks., Conclusions: Our study is the first RCT in China to measure the health effects and heterogeneity of hearing aid interventions. Wearing hearing aids can help improve hearing-related QoL and alleviate the increase in depressive symptoms. The intervention is expected to be applicable to similar settings in other developing countries to combat hearing-related health problems., Trial Registration: Chinese Clinical Trial Registry, ChiCTR1900024739 .

Background: Hearing loss is quite prevalent and can be related to people's quality of life. To our knowledge, there are limited studies assessing the efficacy of hearing interventions on quality of life in adults. Therefore, we aim to conduct a randomized controlled trial (RCT) to determine the impact and cost-effectiveness of community-based hearing rehabilitation on quality of life among Chinese adults with hearing loss., Methods/design: In this two-arm feasibility study, participants aged 16 and above with some degree of hearing loss (n = 464) will be recruited from Linyi City, Shandong Province. They are randomly assigned to the treatment group or the control group. Those in the treatment group are prescribed with hearing aids, while those in the control group receive no intervention. Reinstruction in use of devices is provided for the treatment group during booster visits held 12 months post-randomization or unscheduled interim visits when necessary. Data are collected at baseline and the follow-up 20 months later. The primary outcome is changes in quality of life over a 20-month study period. Secondary outcomes include sub-dimensions in quality of life, physical functioning, chronic diseases, cognitive function, depression, social support, hospitalizations, falls, and healthcare costs. Finally, we will evaluate whether hearing aids intervention is cost-effective to apply in a large scale., Discussion: The trial is designed to evaluate the impact and cost-effectiveness of a community-based rehabilitation intervention on quality of life among Chinese adults with hearing loss. We hope that it would help improve the well-being for Chinese adults and provide references in policy and practice for China and other countries., Trial Registration: Chinese Clinical Trial Registry ChiCTR1900024739 .

Background: Hearing impairment is a common chronic condition which can be closely related to people's health. However, current studies on this topic are quite limited in developing countries, and few with standardized audiometric measurement and multiple health outcomes. Therefore, we aimed to explore the association between hearing impairment and its severity with physical and mental health among Chinese middle-aged and older adults., Methods: We obtained data from two sources: (1) China Health and Retirement Longitudinal Study (CHARLS) 2011, 2013, and 2015, in which hearing impairment was measured by asking whether participants aged 45 years old had hearing problems; and (2) Hearing Survey 2019, the baseline survey of a randomized controlled trial conducted in Shandong Province of China, including 376 middle-aged and older participants. The severity of hearing impairment was identified by pure tone average of hearing thresholds at 0.5, 1, 2, and 4 kHz., Results: In CHARLS, 1248 (8.36%) participants suffered from hearing impairment at baseline, and hearing-impaired individuals were more likely to have chronic diseases, impaired activities of daily living (ADLs), impaired instrumental activities of daily living (IADLs) and depressive symptoms. For the 376 hearing-impaired participants in Hearing Survey 2019, 30.32, 38.30 and 31.38% of them had moderate, severe and profound hearing impairment, respectively. As the severity of hearing impairment increased, individuals were likely to have impaired ADLs, impaired IADLs and depressive symptoms., Conclusions: Hearing impairment and its severity were closely related to multiple physical and mental health outcomes among Chinese middle-aged and older adults. Actions should be taken to prevent and treat hearing impairment, so as to improve people's health and well-being.
