Effectiveness of the lay health advisor program on oral function and quality of life in aboriginal older adults: A randomized controlled trial

BACKGROUND

Aboriginal older adults residing in remote areas have poor oral function due to inadequate access to healthcare services. Lay health advisor (LHA) strategies can fill capacity shortages of healthcare professionals in rural communities and increase population acceptance of health care or healthy behaviours.

OBJECTIVE(S)

To evaluate the effectiveness the LHA program on oral function and oral health-related quality of life (OHRQoL) among older adults in aboriginal community.

METHODS

Participants were randomly assigned to an experimental group (EG; n = 122) and a control group (CG; n = 118). All participants performed oral exercises, and the EG received additional one-on-one 30-min lessons by an LHA over 4 weeks. Data were collected through face-to-face interview and oral examination. The generalized estimating equation model was used to analyse changes in outcomes over time.

RESULTS

The EG exhibited significantly greater improvement in swallowing (β = .63) at the 6-month follow-up and in masticatory performance (β = .52) and pronunciation of the syllable/pa/ (β = 2.65) at the 2-week follow-up than the CG did. The EG had a significantly lower plaque control record (β = -.14) and plaque index (β = -.30) at the 3-month follow-up than the CG did. Moreover, the OHRQoL was significantly increased at 6-months follow-up in the EG (p = .010).

CONCLUSION

The LHA program had positive effects on chewing, swallowing and plaque control in aboriginal older adults. LHA group also experienced positive long-term effect on OHRQoL after intervention.

Long-term effects of a lay health advisor intervention on immigrant children's dental caries and maternal preventive behaviour: A randomized controlled trial

OBJECTIVES

An oral health disparity exists between native and immigrant children in Taiwan. This study evaluated the long-term effectiveness of a lay health advisor (LHA) intervention on immigrant children's dental caries and maternal preventive behaviours.

METHODS

Fifty-one immigrant mother-child pairs were randomly assigned to LHA intervention (n = 23) and control (n = 28) groups. Mothers in the LHA group received a four-chapter one-on-one lesson plan, which included dental caries-related knowledge, brushing techniques, caries prevention and free preventive services, from the LHA over 4 weeks. Mothers in the control group received only a health brochure. Baseline and 1-week, 2-month, and 8-month follow-up information was collected using dental examinations and questionnaires.

RESULTS

The mean ages of the children in the LHA and control groups were 4.0 ± 1.4 and 4.2 ± 1.5, respectively. The decayed, missing due to caries, filled teeth (dmft) index in the LHA and control groups was 4.8 ± 6.0 and 5.4 ± 5.4, respectively, at baseline. At the 8-month postintervention follow-up, the number of filled teeth (ft) in the LHA group was higher than that in the control group (β = 8.3, P = .033). The effect size (ES) demonstrated an upward trend at 1-week, 2-month and 8-month follow-ups in ft (ES = 0.21, 0.50 and 0.59, respectively) and a decrease in the number of decayed teeth (dt) (ES = 0.30, 0.43 and 0.57, respectively). The mothers in the LHA group were observed to be 10.9 times more likely than control mothers to assist their children in toothbrushing for 3 min at the 1-week follow-up (95% CI = 1.98-59.40, P = .006).

CONCLUSIONS

The LHA intervention strategy had positive effects on the immigrant children's new dt and ft and on maternal preventive behaviour, such as assisting their children in toothbrushing.

Prostate Cancer Ambassadors: Process and Outcomes of a Prostate Cancer Informed Decision-Making Training Program

African American men bear a higher burden of prostate cancer than Caucasian men, but knowledge about how to make an informed decision about prostate cancer screening is limited. A lay health advisor model was used to train "Prostate Cancer Ambassadors" on prostate cancer risk and symptoms, how to make an informed decision for prostate-specific antigen screening, and how to deliver the information to members of their community. Training consisted of two, 6-hour interactive sessions and was implemented in three predominantly African American communities over an 8-month period between 2013 and 2014. Following training, Ambassadors committed to contacting at least 10 people within 3 months using a toolkit composed of wallet-sized informational cards for distribution, a slide presentation, and a flip chart. Thirty-two Ambassadors were trained, with more than half being females (59%) and half reporting a family history of prostate cancer. Prostate cancer knowledge improved significantly among Ambassadors ( p ≤ .0001). Self-efficacy improved significantly for performing outreach tasks ( p < .0001), and among women in helping a loved one with making an informed decision ( p = .005). There was also an improvement in collective efficacy in team members ( p = .0003). Twenty-nine of the Ambassadors fulfilled their commitment to reach at least 10 people (average number of contacts per Ambassador was 11). In total, 355 individuals were reached with the prostate cancer information. The Ambassador training program proved successful in training Ambassadors to reach communities about prostate cancer and how to make an informed decision about screening.

Evaluating the stage of change model to a cervical cancer screening intervention among Ohio Appalachian women

Cervical cancer incidence and mortality rates are disproportionally high among women living in Appalachia Ohio. This study used the Transtheoretical Model to examine screening barriers before and after a lay health advisor (LHA) intervention (2005-2009) to increase cervical cancer screening rates. Ohio Appalachian women (n = 90) who were in need of a Pap test, based on risk-appropriate guidelines, were randomized to a 10-month LHA intervention and received two in-person visits, two phone calls, and four mailed postcards targeted to the participant's stage of change. Findings revealed that 63% had forward stage movement 10 months after the intervention. The most frequently reported screening barriers were time constraints, forgetting to make an appointment, and cost. Women who reported the following barriers-doctor not recommending the test; being unable to afford the test; and being embarrassed, nervous, or afraid of getting a Pap test-were less likely to be in the action stage. Understanding the stages of change related to Pap testing and reported barriers among this underserved population may help inform researchers and clinicians of this population's readiness for change and how to set realistic intervention goals.

Once a Navegante, Always a Navegante: Latino Men Sustain Their Roles as Lay Health Advisors to Promote General and Sexual Health to Their Social Network

Little is known about the sustainability of male- and men's health-focused lay health advisors. HoMBReS Por un Cambio was a community-level social network intervention designed to improve sexual health among Latino men who were members of soccer teams. During the year after the intervention implementation, lay health advisors (Navegantes) continued to promote sexual health; over 84% (16 of the 19) Navegantes conducted 9 of 10 primary health promotion activities. Describing where to get condoms was the activity that the most Navegantes reported having conducted. Navegantes had broad reach with their social networks, although the number of Navegantes that conducted each activity differed across the categories of social network members (soccer teammates, nonteammates, and women). Results suggest that HIV-related health disparities may be addressed through lay health advisor interventions because they are sustained after the intervention ends and reach large numbers of community members.

Usefulness of the Audience Response System in training lay health advisors for chronic disease prevention

Lay health promoters (LHPs) have been successful in preventing disease. Given the complexity of health interventions, a crucial component that is necessary for LHPs' success is the training they receive. Engaging methods have the potential to increase LHPs' learning and efficacy to implement health interventions. The Audience Response System (ARS) has successfully facilitated interactive learning in several settings, but has not been used to train LHPs. This paper describes how the ARS was used in LHP training to implement a complex behavioral intervention, reports the training results, and serves as a model for others who work with LHPs.

Latino men's qualitative perspectives on a lay health advisor intervention to promote their sexual health

Lay health advisor (LHA) approaches are a promising strategy to reduce health disparities among communities considered 'hard to reach' by researchers and practitioners. LHAs have addressed a variety of health issues, but limited studies have included men as LHAs. The purpose of this study was to better understand the roles of male LHAs and their male-helping relationships. We used an inductive approach to explore Latino men's perspectives on serving as LHAs for other Latino men and Latino men's views on receiving sexual health information from a male LHA. We collected qualitative data in 2009 and 2010 as part of an LHA intervention designed to reduce the risk of HIV infection among immigrant Latinos through the social networks of soccer teams. We analysed and interpreted data from 30 in-depth interviews with Latino men who served as LHAs and their social networks in North Carolina, USA. Participants shared perceptions on social network importance for immigrant Latinos, facilitators and challenges of helping other men, recommendations for intervention modification and suggestions for future work involving the Latino community. Findings revealed that Latino men are receptive to fulfilling the roles of health advisors and opinion leaders, and can effectively serve as LHAs. Social network members valued the social support they received. Working through sports teams and identifying existing leaders to be LHAs may be a culturally congruent approach to meeting Latino community needs. More research is needed on the potential of male LHAs to address other health issues.

Testing Interventions to Motivate and Educate (TIME): A multi-level intervention to improve colorectal cancer screening

Objective

To test the effectiveness of a colorectal cancer (CRC) screening intervention directed at three levels (clinic, provider, patient) in a primary care setting.

Method

We conducted a group randomized trial (Clinical Trials registration no. NCT01568151) among 10 primary care clinics in Columbus, Ohio that were randomized to a study condition (intervention or usual care). We determined the effect of a multi-level, stepped behavioral intervention on receipt of a CRC screening test among average-risk patients from these clinics over the study period.

Results

Patients (n = 527) who were outside of CRC screening recommendations were recruited. Overall, 35.4% of participants in the intervention clinics had received CRC screening by the end of the study compared to 35.1% of participants who were in the usual care clinics. Time to CRC screening was also similar across arms (HR = 0.97, 95% CI = 0.65–1.45).

Conclusion

The multi-level intervention was not effective in increasing CRC screening among participants who needed a test, perhaps due to low participation of patients in the stepped intervention. Future studies utilizing evidence-based strategies to encourage CRC screening are needed.

•

This study tested the effectiveness of a multi-level CRC screening intervention.

•

There was no difference in receipt of CRC screening between study arms.

•

Innovative strategies need to be developed to improve CRC screening rates.

A snapshot of how latino heterosexual men promote sexual health within their social networks: process evaluation findings from an efficacious community-level intervention

Hombres Manteniendo Bienestar y Relaciones Saludables (HoMBReS) was a community-level social network intervention designed to increase sexual health among Latino heterosexual men who were members of a multicounty soccer league. Process data were collected each month during 18 months of intervention implementation from each of 15 trained Latino male lay health advisors (known as Navegantes) to explore the activities that Navegantes conducted to increase condom and HIV testing among their social network members. The Navegantes reported conducting 2,364 activities, for a mean of 8.8 activities per Navegante per month. The most common activity was condom distribution. Most activities were conducted with men; about 2% were conducted with women. Among activities conducted with men, half were conducted with soccer teammates and half with nonteammates. Results suggest that Latino men's social networks can be leveraged to promote sexual health within the community. Innovative methods that reach large numbers of community members are needed given the lack of prevention resources for populations disproportionately impacted by HIV and STDs.

Randomized trial using hair stylists as lay health advisors to increase donation in African Americans

OBJECTIVE

To test the efficacy of using hair stylists as lay health advisors to increase organ donation among African American clients.

DESIGN

This study was a randomized, controlled intervention trial where we randomized 52 salons (2,789 clients) to receive a 4 session, stylist-delivered health education program (comparison) or a four session brief motivational intervention that encouraged organ donation (intervention). Intervention stylists received a four-hour training in organ donation education and counseling. Organ donation was measured by self-report questionnaire at 4-month posttest as well as by verified enrollment in the Michigan Organ Donor Registry.

SETTING

Hair salons in Michigan urban areas.

PARTICIPANTS

Blacks (n = 2,449), non-Blacks (n = 261) in Michigan.

MAIN OUTCOME MEASURES

Self-reported donation status, registration in Michigan Organ Donor Registry.

RESULTS

At posttest, rates of self-reported positive donation status were 19.8% in the intervention group and 16.0% in the comparison group. In multivariate analyses, intervention participants were 1.7 times (95% Cl = 0.98-2.8) more likely than comparison participants to report positive donation status at posttest. Based on verified organ registry data, enrollment rates were 4.8% and 2%, respectively for the intervention and comparison groups. In multivariate analyses, intervention group members were 4.4 (95% CI = 1.3-15.3) more likely to submit an enrollment card than comparison participants.

CONCLUSION

Clients of hair stylists trained to provide brief motivational intervention for organ donation were approximately twice as likely to enroll in the donor registry as comparison clients. Use of lay health advisors appears to be a promising approach to increase donation among African Americans.

What do men who serve as lay health advisers really do?: Immigrant Latino men share their experiences as Navegantes to prevent HIV

HoMBReS was a lay health adviser (LHA) intervention designed to reduce sexual risk among recently arrived, nonEnglish-speaking Latino men who were members of a multicounty soccer league in central NC. Our community-based participatory research (CBPR) partnership collected, analyzed, and interpreted qualitative life-story narratives to characterize the roles of male LHAs known as Navegantes. Nine Navegantes were interviewed. Their mean age was 39 years (range: 26-62 years); six were from Mexico and three from El Salvador. Navegantes described the function and facilitators of serving as LHAs and identified leverage points for future HIV and STD prevention strategies. They highlighted psychosocial and sociocultural influences on HIV risk, settings for risky behavior, and personal changes from serving as Navegantes. This study provides preliminary evidence that an LHA approach is feasible and appropriate for Latino men, and can be effective in reaching men who might otherwise be difficult to reach.
