Efficacy of technology-based interventions to increase the use of hearing protections among adolescent farmworkers

Hearing Difficulties Among Farmworkers in the México-US Southwest Border Region

Migrant and seasonal farmworkers are a vulnerable population with a potentially high risk for hearing loss due to farm-related noise exposures. Occupational noise-induced hearing loss (NIHL) is permanent, and it is associated with an increased risk for injuries on the job, as well as communication difficulties, isolation, and depression. The México/US border region is one of the most productive agricultural regions in the country, however, no known studies have explored hearing loss among farmworkers in this area. This pilot study was a first step toward measuring and addressing hearing loss and noise exposure among this region's farmworkers. We conducted a cross-sectional survey to estimate the prevalence of subjective hearing difficulties among Yuma County, Arizona farmworkers. Survey interviews took place during a late-night farmworker health fair from 2 am to 6 am to accommodate local farms' labor schedules. Multivariable regression adjusted for demographic and work covariates estimated subjective hearing loss prevalence ratios. Among 132 farmworker participants, 36% reported they have or might have hearing loss, and 62% reported no hearing loss. Subjective hearing loss prevalence was lower in farmworkers who report not working in noise compared to prevalence in farmworkers who work in noise [prevalence ratio, 0.44 (95% CI 0.23-0.82)]. This report contributes to understanding the perception of hearing-related health and occupational exposures among farmworkers in the México-US Southwest border region. The information from this line of research will inform appropriate safety measures known to lower the risk of experiencing occupational NIHL.

Community Health Workers' Role in Addressing Farmworker Health Disparities

Community health workers (CHWs) are uniquely positioned to connect migrant and seasonal farmworkers to health promotion and clinical services. However, research on CHWs' experiences, particularly related to their provision of health education to farmworkers, is limited. To explore CHWs' practices and challenges in conducting health education outreach, we conducted three focus group discussions with farmworker health CHWs (N = 28) in North Carolina in the spring of 2020. We analyzed the focus group transcripts, and we compared the code outputs, thematic code summaries, and memos maintained throughout the analytic process to examine the experiences of CHWs in acquiring and disseminating health information and resources, including use of technology. We identified three themes related to CHWs' experiences providing health information to farmworkers. First, CHWs described short-term preparation, immediately before providing health outreach, and long-term activities, devoted to maintaining and improving their capacity to provide relevant health information to farmworkers. Second, they described their use of health education delivery methods, including open-ended questions, participatory and interactive approaches, and non-verbal aids. Third, participants described their current use of technology and related challenges, as well as the technology needed to enhance health outreach, including internet access. Findings reveal opportunities to improve farmworker health education through professional development for CHWs, identification of preferred methods of health education delivery to farmworkers, and provision of technology to farmworker-serving organizations. Establishing rural internet access and equipping outreach organizations with technology would position CHWs to be maximally effective as they strive to reduce farmworkers' health inequities.Abbreviations: CHW: Community health worker; FGD: focus group discussion; NC: North Carolina.

A Test of Social Cognitive Theory to Increase Hearing Protection Use in Swine Buildings

Farming ranks among the top occupations for which workers are at risk for noise-induced hearing loss (NIHL), an irreversible yet preventable condition. Hearing Protection Devices (HPDs) (i.e., earmuffs and ear plugs) are effective at preventing expo- sure to noise; however, few farmers report consistent use. The purpose of this study was to test an intervention based on Social Cognitive Theory with interactive smartphone technology to increase the use of HPDs among swine facility workers. A pilot, quasi-experimental study was implemented among 72 younger adult swine workers. Participants were randomly assigned to one of three groups. Group 1 received HPDs (e.g., earmuffs and ear plugs). Group 2 received the same HPDs as Group 1 and was also instructed to use a smartphone application to track their use of hearing protection for 60 days. Group 3 received the HPDs and instructions on using a smartphone app for tracking the use of hearing protection and setting daily goals for hearing protection use. Use of hearing protection was assessed via an online survey prior to the intervention (i.e., "baseline"), immediately after the post-intervention, and at a 3-month follow-up. Compared to baseline use, all three groups reported increased use of hearing protection immediately post-intervention. However, this increase was not maintained at a 3-month follow-up for two of the study groups. Group 3 (HPD, tracking, and goal-setting app) showed the greatest increase in the use of HPDs from baseline to immediate post-intervention; however, Group 1 (HPD only) showed the greatest sustained increase from baseline to the 3-month follow-up. Modifying the environment by supplying HPDs was effective in increasing HPD use among swine facility workers. Improving access to hearing protection devices alone may lead to sustained changes in behavior.

Online, Asynchronous Hearing Education and Research Project for Ethnically Diverse Adolescents via Interprofessional Collaboration and Electronic Service-Learning During the COVID-19 Pandemic: A Pilot Study on the Needs and Challenges

Purpose This study discusses the creation of an online, asynchronous presentation to educate adolescents about prevention of noise-induced hearing loss (NIHL) through interprofessional collaborations and electronic service-learning (eSL) during the COVID-19 pandemic. Method The Hearing Education and Research (HEAR) presentation, which included activities and videos to educate a group of ethnically diverse adolescents (n = 100) on NIHL, was created by 11 doctor of audiology (AuD) students through online collaborations toward course-related eSL requirements. Adolescents responded to a baseline survey to assess hearing health-related behaviors prior to reviewing the presentation. A postprogram survey was administered 1 week after the presentation to assess change in knowledge and attitudes toward NIHL prevention. Online collaborations with schoolteachers helped with project implementation. Postreflection papers written by AuD students regarding the eSL activities were analyzed. Lastly, suggestions from a focus group of educators were included that highlight the role of interprofessional collaborations to enhance school-based hearing conservation opportunities. Results The HEAR presentation resulted in changes in knowledge about NIHL among the adolescents. Postreflection papers by the AuD students indicated that the eSL activity served as a high-impact pedagogical assignment, especially during the academic challenges of the pandemic. Feedback from a focus group of schoolteachers helped outline ideas for future implementation of sustainable hearing conservation programs in school settings. Conclusion The pilot data collected in this study serve as a proof of concept for future hearing conservation projects in school-based settings via interprofessional collaborations and by engaging university students via eSL.

Health Education Intervention on Hearing Health Risk Behaviors in College Students

Young people, like college students, are at risk of hearing loss from prolonged and excessive exposure to loud sounds. However, behavioral interventional studies on them are inadequate. This study explored the application of a health belief model to the health education intervention on college students for improving hearing health knowledge, health belief, and hearing behaviors. From November 2017 to September 2018, a cluster randomized controlled trial was conducted, enrolling 830 college students, with 419 in the intervention group and 411 in the control group. The intervention group received a 3-month hearing health education, while the control group received no intervention. The information of hearing health knowledge, health belief, and hearing behaviors were collected using hearing health questionnaires before the intervention, after the intervention, and 3 months after the intervention cessation. The intervention significantly improved hearing health knowledge, health belief, perceived severity, and self-efficacy in female students, and effectively reduced the frequency of using headphones per day, duration of using headphones each time, and proportion of using headphones at high volume in female students, and reduced the behaviors of sleeping with headphones listening in females and males. Therefore, this study confirms the effectiveness of health belief model-based intervention for changing hearing loss-related risk behaviors.

Community-based program to increase use of hearing conservation practices among farm and rural youth: a cluster randomized trial of effectiveness

BACKGROUND

Noise exposure and associated hearing loss affects an estimated 2 million farm youth who are exposed as farm residents, farm family workers, hired workers, children of migrant or seasonal workers, and farm visitors. Risk factors for farm youth include frequent exposure to high farm noise; farm work from an early age, and exposure to high recreational noise (e.g., firearms, ATVs, and personal listening devices).

METHODS

This study compared the effectiveness of two interventions and control. The programs included a community-based interactive youth educational program alone (Group A), a community-based interactive youth educational program followed by an Internet-based booster (Group B), and a no-interaction control (Group C). The study used a cluster randomized control design, with equal allocation ratio to each cluster, without blinding. Inclusion criteria included enrollment in grade 4, parental consent, English speaking, and attending a community-based educational event included in the cluster sampling. A total of 1979 youth were enrolled at 36 sites distributed across the 3 study arms in the following distribution: N = 662 in 13 sites (Group A), N = 680 in 12 sites (Group B), and N = 637 in 11 sites (Group C).

RESULTS

Comparison with pre-intervention data showed no difference in intent to use hearing conservation strategies in experimental groups. However, knowledge and attitudes toward hearing conservation were improved in the groups receiving the Internet-based booster. Participants reported frequent exposure to sources of hazardous noise (e.g., loud sporting events, firecrackers, personal listening devices).

CONCLUSIONS

It is feasible and acceptable to incorporate hearing health education into an already existing system designed to deliver health and safety educational programming to farm and rural youth. The program was adopted by the partner agency for dissemination to up to 100,000 youth annually. Results of this study inform future intervention studies, interventions aimed at farm youth, and interventions to increase use of hearing conservation strategies, as well as offer a base for developing programs for non-English speaking children.

Smartphone Apps in the Context of Tinnitus: Systematic Review

Smartphones containing sophisticated high-end hardware and offering high computational capabilities at extremely manageable costs have become mainstream and an integral part of users' lives. Widespread adoption of smartphone devices has encouraged the development of many smartphone applications, resulting in a well-established ecosystem, which is easily discoverable and accessible via respective marketplaces of differing mobile platforms. These smartphone applications are no longer exclusively limited to entertainment purposes but are increasingly established in the scientific and medical field. In the context of tinnitus, the ringing in the ear, these smartphone apps range from relief, management, self-help, all the way to interfacing external sensors to better understand the phenomenon. In this paper, we aim to bring forth the smartphone applications in and around tinnitus. Based on the PRISMA guidelines, we systematically analyze and investigate the current state of smartphone apps, that are directly applied in the context of tinnitus. In particular, we explore Google Scholar, CiteSeerX, Microsoft Academics, Semantic Scholar for the identification of scientific contributions. Additionally, we search and explore Google's Play and Apple's App Stores to identify relevant smartphone apps and their respective properties. This review work gives (1) an up-to-date overview of existing apps, and (2) lists and discusses scientific literature pertaining to the smartphone apps used within the context of tinnitus.

Feasibility of a mHealth Approach to Nutrition Counseling in an Appalachian State

West Virginia is a rural state with an aging population that may experience barriers to accessing nutritional and lifestyle counseling. This study examined feasibility of an online personalized nutrition tracking application, Good Measures (GM), with patients at seven health care clinics throughout the state. Fourteen healthcare providers and 64 patients 18 years or older with a Body Mass Index (BMI) greater than or equal to 30 and access to the Internet were recruited for this 12-week feasibility study. Patient participants logged meals and exercise into the GM application via smart phone, tablet, or computer and virtually engaged with a Registered Dietitian Nutritionist (RDN) in one-on-one sessions. The primary endpoint was to examine feasibility of the program by usage of the application and feedback questions regarding the benefits and challenges of the application. Participants were predominately white (92%) and female (76%). Minimal improvements in weight and systolic blood pressure were found. Participant attitude survey data declined from 4-weeks to 12-weeks of the intervention. Interestingly though, patients in a rural clinic had lesser declines in attitudes than peri-urban participants. Qualitative feedback data identified participants predominately had a positive overall feeling toward the approach. Participants expressed favorability of RDN access, the variety of foods, but did give suggestions for in-person meetings and more updating of the application. Implementing a technology approach to nutrition in rural areas of West Virginia using a mobile application with RDN access may be one strategy to address public health issues such as obesity.

Efficacy of hearing conservation education programs for youth and young adults: a systematic review

BACKGROUND

Many youth and young adults experience high noise exposure compounded by lack of access to hearing health education. Although the need for hearing health education programs is evident, the efficacy of these programs for youth is unclear. We evaluated the literature for efficacy of various hearing conservation programs aimed at youth and young adults, and analyzed their strengths and limitations.

METHODS

Studies reporting results of hearing conservation or hearing loss prevention programs with youth or young adults, using randomized controlled trials, quasi-experimental designs, experimental design, or qualitative research, and published in peer-reviewed journals in English between 2001 and 2018 were included. Studies were found through searches of selected literature databases (i.e., PubMed, Google Scholar, NIOSH Toxline, and Scopus). Identified publications were assessed for relevance, and data were extracted from the studies deemed relevant.

RESULTS

A total of 10 studies were included. Very little evidence of efficacy of hearing conservation educational programs was found in these studies. Several methodological limitations including lack of rigorous study designs, inadequate power, and application of inappropriate statistical analysis were noted. Some use of technology in programs (e.g., smartphone apps, mobile phone text messages, and computers) was observed, but conclusions as to the effectiveness of these tools were limited by the small number of studies and small sample sizes.

CONCLUSIONS

The number of studies of educational hearing conservation programs for youth and young adults was low. The efficacy of the program was not reported in most studies, and it is difficult to draw public health conclusions from these studies due to their multiple methodological limitations. While use of technology in hearing conservation educational programs offers promise, its effectiveness has not been studied.
