OBJECTIVE: To conduct a randomized controlled trial examining the effects of a social network intervention on health.
METHODS: The Microclinic Social Network Program randomized controlled trial (implemented from June 1, 2011, through December 31, 2014) delivered weekly social-health classroom interventions for 9 to 10 months vs standard of care. Longitudinal multilevel analyses examined end-of-trial and 6-month post-intervention outcomes. Social network effects were estimated via a novel social induction ratio.
RESULTS: We randomized 494 participants, comprising 27 classroom clusters from five neighborhood cohorts. Compared with controls, the intervention showed decreased body weight -6.32 pounds (95% CI, -8.65 to -3.98; overall P<.001), waist circumference -1.21 inches (95% CI, -1.84 to -0.58; overall P<.001), hemoglobin A1c % change -1.60 (95% CI, -1.88 to -1.33; overall P<.001), mean arterial blood pressure -1.83 mm Hg (95% CI, -3.79 to 0.32; overall P<.01), borderline-increased high-density lipoprotein cholesterol 1.09 (95% CI, 0.01-2.17; P=.05; overall P=.01). At 6 months post-intervention, net improvements were: weight change 97% sustained (P<.001), waist circumference change 92% sustained (P<.001), hemoglobin A1c change 82.5% sustained (P<.001), high-density lipoprotein change 79% sustained (overall P=.01), and mean arterial blood pressure change greater than 100% sustained improvement of -4.21 mm Hg (P<.001). Mediation analysis found that diet and exercise did not substantially explain improvements. In the intent-to-treat analysis of social causal induction, the weight-change social induction ratio (SIR) was 1.80 for social-network weight change-meaning that social networks explained the greater weight loss in the intervention than controls. Furthermore, we observed an even stronger weight-loss SIR of 2.83 at 6 months post-intervention.
CONCLUSIONS: Results show intervention effectiveness for improving health in resource-limited communities, with SIR demonstrating that social-network effects helped induce such improvements.

We characterized concentrations of trihalomethanes (THMs), a measure of disinfection byproducts (DBPs), in tap water samples collected from households with utility-supplied water in two rural counties in Appalachian Virginia, and assessed associations with pH, free chlorine, and metal ions which can impact THM formation. Free chlorine concentrations in all samples (n = 27 homes) complied with EPA drinking water guidelines, though 7% (n = 2) of first draw samples and 11% (n = 3) of 5-min flushed-tap water samples exceeded the US Safe Drinking Water Act (SDWA) maximum contaminant level (MCL) for THM (80 ppb). Regression analyses showed that free chlorine and pH were positively associated with the formation of THM levels above SDWA MCLs (OR = 1.04, p = 0.97 and OR = 1.74, p = 0.79, respectively), while temperature was negatively associated (OR = 0.78, p = 0.38). Of the eight utilities serving study households, samples from water served by three different utilities exceeded the EPA MCL for THM. Overall, these findings do not indicate substantial exposures to DBPs for rural households with utility-supplied water in this region of southwest Virginia. However, given the observed variability in THM concentrations between and across utilities, and established adverse health impacts associated with chronic and acute DBP exposure, more research on DBPs in rural Central Appalachia is warranted.

The COVID-19 pandemic has created new digital health care landscapes for the management of substance use and misuse. While telehealth was prohibited for addiction treatment prior to the pandemic, the severity of COVID-19 precipitated telehealth expansion for the delivery of individual and group-based treatment. Research has highlighted benefits and challenges of telehealth; however, little is known about the impacts of telehealth on the quality, use, and effectiveness of treatment. Fewer studies examine how these emerging digital geographies of care transform the spaces and landscapes of substance misuse. This article examines how telehealth affects landscapes of opioid use disorder care in Pennsylvania, West Virginia, and Kentucky during the COVID-19 pandemic. Our findings reveal that while telehealth extends access to treatment for opioid use disorder (OUD), it also creates new care inequities within and between providers and clientele that can undermine effective care and recovery.

BACKGROUND: The present commentary highlights the pressing need for systematic research to assess the implementation and effectiveness of medications for opioid use disorder, used in conjunction with peer recovery support services, to improve treatment outcomes for individuals with opioid use disorder in Central Appalachia. This region, encompassing West Virginia, Eastern Kentucky, Southwest Virginia, East Tennessee, and Western North Carolina, has long grappled with a disproportionate burden of the opioid crisis. Due to a complex interplay of cultural, socioeconomic, medical, and geographic factors, individuals in Central Appalachia face challenges in maintaining treatment and recovery efforts, leading to lower success rates.
METHODS: To address the issue, we apply an exploratory approach, looking at the intersection of unique regional factors with the utilization of medications for opioid use disorder, in conjunction with peer recovery support services. This combined treatment strategy shows promise in addressing crucial needs in opioid use disorder treatment and enhancing the recovery journey. However, there are significant evidence gaps that need to be addressed to validate the expected value of incorporating peer support into this treatment strategy.
CONCLUSIONS: We identify nine obstacles and offer recommendations to address the gaps and advance peer recovery support services research. These recommendations include the establishment of specific partnerships and infrastructure for community-engaged, peer recovery support research; improved allocation of funding and resources to implement evidence-based practices such as peer support and medication-assisted treatment; developing a more precise definition of peer roles and their integration across the treatment and recovery spectrum; and proactive efforts to combat stigma through outreach and education.

OBJECTIVE: Our aim was to explore postpartum individuals\' experiences and perceptions of breastfeeding and International Board Certified Lactation Consultants\' (IBCLC) knowledge and perceptions of maternity care practices and perceived barriers to breastfeeding among their patient populations in Appalachia.
METHODS: Semistructured interviews were conducted with seven IBCLCs and seven postpartum individuals. Interviews were recorded and transcribed. Thematic analysis was conducted to determine emergent themes and subthemes related to knowledge/perceptions, experiences, and barriers to breastfeeding among postpartum individuals, as well as emergent themes associated with the knowledge and perceptions of maternity care practices, easy-/difficult-to-implement Baby-Friendly Hospital Initiative maternity care practices, and perceived barriers to breastfeeding among IBCLCs.
RESULTS: Postpartum individuals recruited from an Appalachian obstetrics/gynecology clinic were aware of the benefits of breastfeeding, but their infant feeding journeys were more stressful than they expected, and they had limited access to lactation support and breastfeeding education/information. IBCLCs identified the benefits of the Baby-Friendly maternity care practices but mentioned some risks, especially when there is a lack of communication and coordination among providers. Environmental and informational barriers were identified by both postpartum individuals and IBCLCs as breastfeeding challenges potentially amenable to change.
CONCLUSIONS: To support postpartum mothers in the Appalachian region, environmental barriers (eg, lack of lactation support) and informational barriers (eg, lack of prenatal education) need to be addressed.

The COVID-19 pandemic produced acute effects on health inequities, yet more enduring impacts in vulnerable populations in rural Appalachia are understudied. This qualitative study included three focus groups with thirty-nine adults (74% female, mean age 52.7 years) to obtain perspectives on the impact of the COVID-19 pandemic on well-being in Martin County, Kentucky, in fall 2022. Grounded Theory was employed using an iterative inductive-deductive approach to capture the lasting effects of the COVID-19 pandemic on health practices and status. Three prominent themes emerged: (1) increased social isolation; (2) household cost of living strains caused by inflation; and (3) higher food prices and diminished food availability causing shifts in food purchasing and consumption. Participants noted that the rising cost of living resulted in residents having to \"choose between medication, food and utilities\". Increased food prices resulted in residents \"stretching\" their food, modifying how they grocery shopped, and limiting meat consumption. Persistent food shortages were exacerbated by there being few grocery stores in the county. Lastly, increased social isolation was profoundly articulated as widely impacting mental health, especially among youth. Our findings underscore the ongoing deleterious effects of inflation and food supply chain disruptions in this rural, geographically isolated community, which resulted in difficult spending choices for residents.

UNASSIGNED: Under-represented subgroups in biomarker research linked to behavioral health trials may impact the promise of precision health. This mixed methods study examines biorepository donations across an Appalachian sample enrolled in a sugary drink reduction intervention trial.
UNASSIGNED: Participants enrolled in the behavioral trial were asked to join an optional biomarker study and were tracked for enrollment and biospecimen returns (stool and/or buccal sample). At 6 months, participants completed a summative interview on decision-making process, experiences collecting samples, and recommendations to encourage biospecimen donation. Return rates were analyzed across demographics (i.e., age, gender, race, education, income, health literacy status, and rurality status) using chi-squares. Qualitative data were content coded with differences compared by biomarker study enrollment and donation choices.
UNASSIGNED: Of the 249 invited participants, 171 (61%) enrolled, and 63% (n = 157) returned buccal samples and 49% (n = 122) returned stool samples. Metro residing participants were significantly more likely (56%) to return stool samples compared to non-metro (39%) counterparts [x2(1) = 6.61; p = 0.01]. Buccal sample return had a similar trend, 67 and 57%, respectively for metro vs. non-metro [x2(1) = 2.84; p = 0.09]. An additional trend indicated that older (≥40 years) participants were more likely (55%) to donate stool samples than younger (43%) participants [x2(1) = 3.39; p = 0.07]. No other demographics were significantly associated with biospecimen return. Qualitative data indicated that societal (66-81%) and personal (41-51%) benefits were the most reported reasons for deciding to donate one or both samples, whereas mistrust (3-11%) and negative perceptions of the collection process (44-71%) were cited the most by those who declined one or both samples. Clear instructions (60%) and simple collection kits (73%) were donation facilitators while challenges included difficult stool collection kits (16%) and inconveniently located FedEx centers (16%). Recommendations to encourage future biorepository donation were to clarify benefits to science and others (58%), provide commensurate incentives (25%), explain purpose (19%) and privacy protections (20%), and assure ease in sample collection (19%).
UNASSIGNED: Study findings suggest the need for biomarker research awareness campaigns. Researchers planning for future biomarker studies in medically underserved regions, like Appalachia, may be able to apply findings to optimize enrollment.

BACKGROUND: Sexual assault nurse examiners are crucial care providers in cases of sexual assault. However, it is not clear whether sexual assault nurse examiner availability differs throughout the 13 states that comprise the Appalachian region of the United States. Therefore, this cross-sectional analysis identified sexual assault nurse examiner availability in 13 states and determined differences in availability by both county-level Appalachian status and county-level rurality status.
METHODS: Data were downloaded from 2 public sexual assault nurse examiner registries for the included 13 states. Descriptive statistics of sexual assault nurse examiner certification type and availability by state were calculated. In addition, bivariate analyses of sexual assault nurse examiner availability by rurality and by Appalachian status were performed using 2-sample z-tests for equality of proportions.
RESULTS: State-level sexual assault nurse examiner availability ranged from 0.34 to 0.86 sexual assault nurse examiners per 100,000 residents. Sexual assault nurse examiner availability in these 13 states did not differ by Appalachian status. However, rural areas had significantly lower sexual assault nurse examiner availability than urban areas in these 13 states.
CONCLUSIONS: These data support previous literature on the need for stronger sexual assault nurse examiner programs in rural areas in the United States. Future research should take sexual assault prevalence into account to determine whether local sexual assault nurse examiner access needs, as well as appropriate support for sexual assault nurse examiners, are being met throughout Appalachian states.

OBJECTIVE: In the US, violations of drinking water regulations are highest in lower-income rural areas overall, and particularly in Central Appalachia. However, data on drinking water use, quality, and associated health outcomes in rural Appalachia are limited. We sought to assess public and private drinking water sources and associated risk factors for waterborne pathogen exposures for individuals living in rural regions of Appalachian Virginia.
METHODS: We administered surveys and collected tap water, bottled water, and saliva samples in lower-income households in two adjacent rural counties in southwest Virginia (bordering Kentucky and Tennessee). Water samples were tested for pH, temperature, conductivity, total coliforms, E. coli, free chlorine, nitrate, fluoride, heavy metals, and specific pathogen targets. Saliva samples were analyzed for antibody responses to potentially waterborne infections. We also shared water analysis results with households.
RESULTS: We enrolled 33 households (83 individuals), 82% (n = 27) with utility-supplied water and 18% with private wells (n = 3) or springs (n = 3). 58% (n = 19) reported household incomes of <$20,000/year. Total coliforms were detected in water samples from 33% (n = 11) of homes, E. coli in 12%, all with wells or springs (n = 4), and Aeromonas, Campylobacter, and Enterobacter in 9%, all spring water (n = 3). Diarrhea was reported for 10% of individuals (n = 8), but was not associated with E. coli detection. 34% (n = 15) of saliva samples had detectable antibody responses for Cryptosporidium spp., C. jejuni, and Hepatitis E. After controlling for covariates and clustering, individuals in households with septic systems and straight pipes had significantly higher likelihoods of antibody detection (risk ratios = 3.28, 95%CI = 1.01-10.65).
CONCLUSIONS: To our knowledge, this is the first study to collect and analyze drinking water samples, saliva samples, and reported health outcome data from low-income households in Central Appalachia. Our findings indicate that utility-supplied water in this region was generally safe, and individuals in low-income households without utility-supplied water or sewerage have higher exposures to waterborne pathogens.

BACKGROUND: People make oral healthcare decisions regardless of having partial information, misinformation, sources that deliberately mislead, or information that is culturally influenced. This is particularly true in the Appalachian culture where oral healthcare decision-making practices are not well understood by researchers and dental professionals. Despite efforts to improve dental care utilization, the Appalachia region remains low in oral healthcare utilization. There is a need for a theory to identify concepts in decision-making when seeking oral healthcare. The theory could be useful in creating oral health interventions. The study objective is to develop a theory to identify concepts that influence oral healthcare decision-making in Appalachia (OHDA).
METHODS: The researchers used a grounded theory qualitative study design to explain data for a theory of OHDA. Participants from Appalachia, in 20-minute interviews, provided insights into concepts that influence OHDA from August 22, 2017 to May 26, 2022. Notes/memos were written during and after the interviews and coding was conducted after the interviews. Open coding categories emerged through constant comparison of responses.
RESULTS: Five overarching concepts that embody OHDA were discovered: Affect (Level of Pain/Emotion/Stress involvement), Awareness, Trust/belief, Resources, and Risk Perception. All participants discussed the impact of social media toward these concepts.
CONCLUSIONS: To influence a person\'s OHDA, public health officials and researchers need to address the person\'s affect, level of awareness, trust/belief, available resources, and risk perception. Social media is very important in awareness concerning oral health information. These factors are important to consider for similar research in oral healthcare utilization at the population level.
