Nonoperative Treatment of Humeral Shaft Fractures With Immediate Functional Bracing Versus Coaptation Splinting and Delayed Functional Bracing: A Retrospective Study

OBJECTIVES

To compare radiographic and clinical outcomes in nonoperative management of humeral shaft fractures treated initially with coaptation splinting (CS) followed by delayed functional bracing (FB) versus treatment with immediate FB.

METHODS

DESIGN

Retrospective cohort study.

SETTING

Academic Level 1 Trauma Center.

PATIENT SELECTION CRITERIA

Patients with closed humeral shaft fractures managed nonoperatively with initial CS followed by delayed FB or with immediate FB from 2016 to 2022. Patients younger than 18 years and/or with less than 3 months of follow-up were excluded.

OUTCOME MEASURES AND COMPARISONS

The primary outcome was coronal and sagittal radiographic alignment assessed at the final follow-up. Secondary outcomes included rate of failure of nonoperative management (defined as surgical conversion and/or fracture nonunion), fracture union, and skin complications secondary to splint/brace wear.

RESULTS

Ninety-seven patients were managed nonoperatively with delayed FB (n = 58) or immediate FB (n = 39). Overall, the mean age was 49.9 years (range 18-94 years), and 64 (66%) patients were female. The immediate FB group had less smokers ( P = 0.003) and lower incidence of radial nerve palsy ( P = 0.025), with more proximal third humeral shaft fractures ( P = 0.001). There were no other significant differences in demographic or clinical characteristics ( P > 0.05). There were no significant differences in coronal ( P = 0.144) or sagittal ( P = 0.763) radiographic alignment between the groups. In total, 33 (34.0%) humeral shaft fractures failed nonoperative management, with 11 (28.2%) in the immediate FB group and 22 (37.9%) in the delayed FB group ( P = 0.322). There were no significant differences in fracture union ( P = 0.074) or skin complications ( P = 0.259) between the groups.

CONCLUSIONS

This study demonstrated that nonoperative treatment of humeral shaft fractures with immediate functional bracing did not result in significantly different radiographic or clinical outcomes compared to treatment with CS followed by delayed functional bracing. Future prospective studies assessing patient-reported outcomes will further guide clinical decision making.

Testing the feasibility of the QuitAid smoking cessation intervention in a randomized factorial design in an independent, rural community pharmacy

BACKGROUND

Adult smoking rates in the USA are highest in economically depressed rural Appalachia. Pharmacist-delivered tobacco cessation support that incorporates medication therapy management (such as the QuitAid intervention) is a promising approach to address this need.

METHODS

Twenty-four adult smokers recruited between September and November 2021 through an independent pharmacy in rural Appalachia were randomized in a non-blinded 2 × 2 × 2 factorial design to (1) pharmacist delivered QuitAid intervention (yes vs. no); (2) combination nicotine replacement therapy (NRT) gum + NRT patch (vs. NRT patch); and/or (3) 8 weeks of NRT (vs. standard 4 weeks). Participants received 4 weeks of NRT patch in addition to the components to which they were assigned. Participants completed baseline and 3-month follow-up assessments. Primary outcomes were feasibility of recruitment and randomization, retention, treatment adherence, and fidelity.

RESULTS

Participants were recruited in 7 weeks primarily through a referral process, commonly referred to as ask-advise-connect (61%). Participants were on average 52.4 years old, 29.2% were male and the majority were white (91.6%) and Non-Hispanic (91.7%). There was a high level of adherence to the interventions, with 85% of QuitAid sessions completed, 83.3% of the patch used, and 54.5% of gum used. Participants reported a high level of satisfaction with the program, and there was a high level of retention (92%).

CONCLUSIONS

This demonstration pilot randomized controlled study indicates that an ask-advise-connect model for connecting rural smokers to smoking cessation support and providing QuitAid for smoking cessation is feasible and acceptable among rural Appalachian smokers and independent pharmacists. Further investigation into the efficacy of a pharmacist-delivered approach for smoking cessation is needed.

Impact of a Cancer Education Curriculum on Appalachian Kentucky Middle and High School Students

Appalachian Kentucky is disproportionately affected by elevated cancer incidence and mortality rates. This disparity is driven by inequities in health behaviors and social determinants of health including decreased education attainment levels that cause lower health literacy. To increase cancer literacy in the region, a three-part cancer education curriculum was designed for Appalachian Kentucky middle and high school students. This study was designed to evaluate the effect the curriculum had on students' cancer literacy. The curriculum lessons were disseminated to Appalachian Kentucky middle and high school teachers who engaged 223 students with the material. For each lesson, students filled out a 10-question pretest and an identical 10-question posttest. The average and median percent of correct responses from the pre- to posttests were analyzed. The average percentage of correct responses significantly increased from 40% to 70%, 52% to 69%, and 33% to 53% on lessons 1, 2, and 3, respectively. A significant increase in the average percentage of correct responses on each individual question was also observed. The results demonstrate that the three-part cancer education curriculum intervention can significantly increase Appalachian Kentucky middle and high school students' cancer literacy. Increased cancer knowledge has the potential to encourage behavioral modifications that could reduce cancer incidence and mortality rates over time. Future work will include further improving the content relative to the target age/grade level and implementing the material with a broader group of teachers and students.

County incidence and geospatial trends of early-onset hypertensive disorders of pregnancy in Kentucky, 2008-2017

BACKGROUND

Early-onset hypertensive disorders of pregnancy (eHDP) are associated with more severe maternal and infant outcomes than later-onset disease. However, little has been done to evaluate population-level trends. Therefore, in this paper, we seek to address this understudied area by describing the geospatial and temporal patterns of county-level incidence of eHDP and assessing county-level demographics that may be associated with an increased incidence of eHDP.

METHODS

Employing Kentucky certificates of live and stillbirth from 2008-2017, this ecological study detected county-level clusters of early-onset hypertensive disorders of pregnancy using SaTScan, calculated average annual percent change (AAPC) with a join point analysis, and identified county-level covariates (% of births to women ≥ 35 years of age, % with BMI ≥ 30 kg/m², % currently smoking, % married, and % experienced eHDP) with a fixed-effects negative binomial regression model for longitudinal data with an autoregressive (AR) correlation structure offset with the natural log of the number of births in each county and year.

RESULTS

County-level incidence of eHDP had a non-statistically significant increase of almost 3% (AAPC: 2.84, 95% CI: -4.26, 10.46), while maternal smoking decreased by almost 6% over the study period (AAPC:-5.8%, 95%CI: -7.5, -4.1), Risk factors for eHDP such as pre-pregnancy BMI ≥ 30 and proportion of births to women ≥ 35 years of age increased by 2.3% and 3.4% respectively (BMI AAPC:2.3, 95% CI: 0.94, 3.7; ≥ 35 years AAPC:3.4, 95% CI: 0.66, 6.3). After adjusting for race, county-level proportions of college attainment, and maternal smoking throughout pregnancy, counties with the highest proportion of births to women with BMI ≥ 30 kg/m² reported an eHDP incidence 20% higher than counties with a lower proportion of births to mothers with a BMI ≥ 30 kg/m² and a 20% increase in eHDP incidence (aRR = 1.20, 95% CI: 1.00, 1.44). We also observed that counties with the highest proportion vs. the lowest of mothers ≥ 35 years old (> 6.1%) had a 26% higher incidence of eHDP (RR = 1.26, 95%CI: 1.04, 1.50) compared to counties with the lowest incidence (< 2.5%). We further identified two county-level clusters of elevated eHDP rates. We also observed that counties with the highest vs. lowest proportion of mothers ≥ 34 years old (> 6.1% vs. < 2.5%) had a 26% increase in the incidence of eHDP (RR = 1.26, 95% CI: 1.04, 1.50). We further identified two county-level clusters of elevated incidence of eHDP.

CONCLUSIONS

This study identified two county-level clusters of eHDP, county-level covariates associated with eHDP, and that while increasing, the average rate of increase for eHDP was not statistically significant. This study also identified the reduction in maternal smoking over the study period and the concerning increase in rates of elevated pre-pregnancy BMI among mothers. Further work to explore the population-level trends in this understudied pregnancy complication is needed to identify community factors that may contribute to disease and inform prevention strategies.

Adult asthma associated with roadway density and housing in rural Appalachia: the Mountain Air Project (MAP)

BACKGROUND

Appalachian Kentucky is a rural area with a high prevalence of asthma among adults. The relative contribution of environmental exposures in the etiology of adult asthma in these populations has been understudied.

OBJECTIVE

This manuscript describes the aims, study design, methods, and characteristics of participants for the Mountain Air Project (MAP), and focuses on associations between small area environmental exposures, including roadways and mining operations, and lifetime and current asthma in adults.

METHODS

A cohort of residents, aged 21 and older, in two Kentucky counties, was enrolled in a community-based, cross-sectional study. Stratified cluster sampling was used to select small geographic areas denoted as 14-digit USGS hydrologic units (HUCs). Households were enumerated within selected HUCs. Community health workers collected in-person interviews. The proximity of nearby active and inactive coal mining operations, density of oil and gas operations, and density of roadways were characterized for all HUCs. Poisson regression analyses were used to estimate adjusted prevalence ratios.

RESULTS

From 1,459 eligible households contacted, 1,190 individuals were recruited, and 972 persons completed the interviews. The prevalence of lifetime asthma was 22.8%; current asthma was 16.3%. Adjusting for covariates, roadway density was positively associated with current asthma in the second (aPR = 1.61; 95% CI 1.04-2.48) and third tertiles (aPR = 2.00; 95% CI 1.32-3.03). Increased risk of current asthma was associated with residence in public, multi-unit housing (aPR = 2.01; 95% CI 1.27-3.18) compared to a residence in a single-family home. There were no notable associations between proximity to coal mining and oil and gas operations and asthma prevalence.

CONCLUSIONS

This study suggests that residents in rural areas with higher roadway density and those residing in public housing units may be at increased risk for current asthma after accounting for other known risk factors. Confirming the role of traffic-related particulates in producing high asthma risk among adults in this study contributes to the understanding of the multiple environmental exposures that influence respiratory health in the Appalachia region.

Increased odds of mortality from non-malignant respiratory disease and lung cancer are highest among US coal miners born after 1939

OBJECTIVES

Coal miners suffer increased mortality from non-malignant respiratory diseases (NMRD), including pneumoconioses and chronic obstructive pulmonary disease, compared with the US population. We characterised mortality trends from NMRD, lung cancer and ischaemic heart disease (IHD) using data from the Federal Black Lung Program, National Coal Workers' Health Surveillance Program and the National Death Index.

METHODS

We compared mortality ORs (MORs) for NMRD, lung cancer and IHD in former US coal miners to US white males. MORs were computed for the study period 1979-2017 by birth cohort (<1920, 1920-1929, 1930-1939, ≥1940), with a subanalysis restricted to Central Appalachia.

RESULTS

The study population totalled 235 550 deceased miners, aged >45 years. Odds of death from NMRD and lung cancer across all miner birth cohorts averaged twice those of US males. In Central Appalachia, MORs significantly increased across birth cohorts. There was an eightfold increase in odds of death from NMRD among miners born after 1940 (MORBC≥1940 8.25; 95% CI 7.67 to 8.87). Miners with progressive massive fibrosis (PMF) were younger at death than those without PMF (74 vs 78 years; p<0.0001). We observed a pattern of reduced MORs from IHD in coal miners compared with national and regional counterparts.

CONCLUSION

US coal miners have excess mortality from NMRD and lung cancer compared with total US and Appalachian populations. Mortality is highest in the most recent birth cohorts, perhaps reflecting increased rates of severe pneumoconiosis.

Sociodemographic Factors and Health Insurance Coverage Are Associated with Invasive Breast Cancer in Tennessee: Appalachian and Non-Appalachian County Comparison

Background:

Tennessean women experience the 12th highest breast cancer (BC) mortality in the United States. Yet, few studies have examined BC outcomes among Tennessean women in and outside of Appalachia. We examined whether sociodemographic factors and health insurance status were associated with invasive BC in Tennessee by Appalachian and non-Appalachian county designation.

Materials and Methods:

Using the Tennessee Cancer Registry, we identified 52,187 women, aged ≥18, diagnosed with BC between 2005 and 2015. Multivariable logistic regression was performed to examine associations between invasive BC and sociodemographic characteristics, health insurance coverage, and county designation (Appalachian/non-Appalachian). Regression analyses stratified by county designation were subsequently performed.

Results:

In Tennessee, younger women had lower odds of invasive BC diagnosis (<45: odds ratio [OR] = 0.74, 95% confidence interval [CI] = 0.67–0.81; 55–64: OR = 0.91, 95% CI = 0.84–0.97) compared to women ≥65. Married Tennessean women had 12% (95% CI = 1.04–1.21) higher odds of invasive BC than single women. Further, both public (OR = 1.81, 95% CI = 1.41–2.33) and private (OR = 1.36, 95% CI = 1.06–1.76) health insurance were found to increase odds of invasive BC compared to no insurance/self-pay. Results from the subpopulation analyses were largely consistent with overall findings. In Appalachian counties, women on public health insurance had increased odds (OR = 1.42, 95% CI = 1.00–2.03) of invasive BC compared to uninsured/self-pay women, while in non-Appalachian counties, women insured both publicly (OR = 2.25, 95% CI = 1.57–3.24) and privately (OR = 1.68, 95% CI = 1.16–2.24) had increased odds of invasive BC.

Conclusions:

The results identify risk factors for Tennessean women in Appalachian and non-Appalachian counties whose malignancies evaded early detection, increasing risk of mortality.

Factors Influencing Cardiovascular Risk Factors and Health Perception Among Kentuckians Living in Appalachia

BACKGROUND

Cardiovascular disease (CVD) and risk factors for CVD are prevalent among Appalachians from Kentucky. Appalachian men and women have high rates of engagement in unhealthy behaviors and poor physical health measures that increase their risk for CVD.

OBJECTIVE

In this study, the relationship among gender, CVD risk factors, and health perception in Appalachians from Kentucky was explored.

METHODS

This cross-sectional secondary analysis is from a randomized controlled trial on CVD health in rural Kentucky. To assess gender differences in smoking history, χ was used. Independent t tests compared the mean between participants 50 years or younger and those older than 50 years with differences in body mass index (BMI), waist circumference, systolic and diastolic blood pressure, hemoglobin A1C, total cholesterol, and physical activity. A multivariate linear regression analysis assessed variables predicting the outcome of health perception.

RESULTS

Most participants had a mean BMI of 33 kg/m and 94.3% of men used smokeless tobacco compared to 5.7% of the women. Differences existed between gender and current, ever, or never smoked (P < .001). Women had higher total cholesterol levels but men had higher waist circumference. Participants older than 50 years had higher engagement in physical activity than did those 50 years or younger. Higher BMI and hemoglobin A1C level were significant predictors of worse health perception (P ≤ .05). For every unit increase in the physical activity scale, there was a 0.2-unit improvement in health perception (P ≤ .001).

CONCLUSION

Appalachians from Kentucky have many CVD risk factors. Minimal engagement in preventative measures against CVD can worsen patient outcomes.

Increased Odds of Incident Alzheimer's Disease and Related Dementias in Presence of Common Non-Cancer Chronic Pain Conditions in Appalachian Older Adults

BACKGROUND

There is a growing concern regarding the increasing prevalence of common non-cancer chronic pain conditions (NCPCs) and their possible association with Alzheimer's disease and related dementias (ADRD). However, large population-based studies are limited, especially in Appalachian and other predominantly rural, underserved populations who suffer elevated prevalence of both NCPCs and known ADRD risk factors.

OBJECTIVES

We investigated the relation of NCPC to risk of incident ADRD in older Appalachian Medicare beneficiaries and explored the potential mediating effects of mood and sleep disorders.

METHODS

Using a retrospective cohort design, we assessed the overall and cumulative association of common diagnosed NCPCs at baseline to incident ADRD in 161,573 elders ≥65 years, Medicare fee-for-service enrollees, 2013-2015. NCPCs and ADRD were ascertained using claims data. Additional competing risk for death analyses accounted for potential survival bias.

MAIN FINDINGS

Presence of any NCPC at baseline was associated with significantly increased odds for incident ADRD after adjustment for covariates [adjusted odds ratio (AOR) = 1.26 (1.20, 1.32), p < .0001]. The magnitude and strength of this association increased significantly with rising burden of NCPCs at baseline [AOR for ≥4 vs. no NCPC = 1.65 (1.34, 2.03), p-trend = .01]. The addition of depression and anxiety, but not sleep disorders, modestly attenuated these associations [AORs for any NCPC and ≥4 NCPCs, respectively = 1.16 (1.10, 1.22) and 1.39 (1.13, 1.71)], suggesting a partial mediating role of mood impairment. Sensitivity analyses, multinomial logistic regressions accounting for risk of death, yielded comparable findings.

CONCLUSION

In this large cohort of older Appalachian Medicare beneficiaries, baseline NCPCs showed a strong, positive, dose-response relationship to odds for incident ADRD; this association appeared partially mediated by depression and anxiety. Further longitudinal research in this and other high-risk, rural populations are needed to evaluate the causal relation between NCPC and ADRD.

Persistent disparities in smoking among rural Appalachians: evidence from the Mountain Air Project

BACKGROUND

Adult smoking prevalence in Central Appalachia is the highest in the United States, yet few epidemiologic studies describe the smoking behaviors of this population. Using a community-based approach, the Mountain Air Project (MAP) recruited the largest adult cohort from Central Appalachia, allowing us to examine prevalence and patterns of smoking behavior.

METHODS

A cross-sectional epidemiologic study of 972 participants aged 21 years and older was undertaken 2015-2017, with a response rate of 82%. Prevalence ratios and 95% confidence intervals for current smoking (compared to nonsmokers) were computed for the entire cohort then stratified by multiple characteristics, including respiratory health. Adjusted prevalence ratios for current smoking versus not smoking were also computed.

RESULTS

MAP participants reported current smoking prevalence (33%) more than double the national adult smoking prevalence. Current smoking among participants with a reported diagnosis of chronic obstructive pulmonary disease and emphysema was 51.5 and 53.3%, respectively. Compared to participants age 65 years and older, those age 45 years or younger reported double the prevalence of smoking (PR: 2.04, 95% CI: 1.51-2.74). Adjusted analyses identified younger age, lower education, unmet financial need, and depression to be significantly associated with current smoking.

CONCLUSIONS

Despite declining rates of smoking across the United States, smoking remains a persistent challenge in Central Appalachia, which continues to face marked disparities in education funding and tobacco control policies that have benefitted much of the rest of the nation. Compared with national data, our cohort demonstrated higher rates of smoking among younger populations and reported a greater intensity of cigarette use.

Tobacco-Free Ambassador Partnership: Empowering Youth Advocates in Appalachian Communities

Kentucky youth (14.3%) smoke more cigarettes as compared to the U.S. average (8.8%), and Appalachian communities suffer disproportionately from tobacco-related diseases such as lung cancer. Training youth to become advocates is an effective strategy to improve health equity. This article describes the development and impact of a youth advocacy program to promote tobacco control policies in Appalachian Kentucky. Phase I (2017-2018): two ½-day trainings followed by monthly meetings with one high school (n = 20 youth). Trainings provided information on tobacco use, consequences, industry tactics, evidence-based tobacco control, and advocacy skills. Results provided support for expansion to Phase II (2018-20119): A 1-day training followed by monthly information sharing implemented in three counties (N = 80). Youth were surveyed before and 6-months posttraining during both phases. Phase I: At posttraining, 85% of youth believed they could reduce the amount of tobacco use in their community versus 66% at baseline. More students tried at least once to convince school or government officials to be more concerned about tobacco use (77% vs. 47%). Phase II: More students supported tobacco policies at posttraining survey and realized policies are an effective strategy to reduce tobacco use. At posttraining survey, students reported greater interpersonal confidence talking with others about tobacco-related issues, with a 24% increase in confidence talking with adults in their communities, as well as greater advocacy self-efficacy. Youth in Appalachia demonstrate desire to influence tobacco use and policy to improve health equity. Findings reinforce the need for collaborative public health interventions to promote ongoing training and support for youth living in high-risk communities.

Appalachian disparities in tobacco cessation treatment utilization in Medicaid

BACKGROUND

Kentucky Medicaid enrollees, particularly those in the rural Appalachian region, face disproportionate smoking rates and tobacco-related disease burden relative to the rest of the United States (US). The Affordable Care Act (ACA) mandated tobacco cessation treatment coverage by the US public health insurance program Medicaid. Medicaid coverage was also expanded in Kentucky, in 2013, with laxer income eligibility requirements. This short report describes tobacco use incidence and tobacco cessation treatment utilization, comparing by Appalachian status before and after ACA-mandated cessation treatment coverage.

METHODS

The study design was a retrospective cross-sectional analysis from 2013 to 2015. Subjects were Medicaid enrollees with 1) diagnosis of any tobacco use (2013 n = 541,349; 2014 n = 864,183; 2015 n = 1,090,274); and/or (2) procedure claim for tobacco cessation counseling, and/or (3) pharmaceutical claim for varenicline or any nicotine replacement product. Primary measures included tobacco use incidence and proportion of users receiving cessation treatment. Analysis was via chi square testing of change by year.

RESULTS

Overall, the proportion of tobacco users utilizing cessation treatment decreased (4.75% tobacco users in 2013; 3.15% in 2015). Tobacco users receiving counseling decreased from 2.06% pre-ACA (2013) to 1.06% post-ACA (2015, p < 0.001), as did the proportion receiving nicotine replacement products post-ACA (2.69% in 2013 to 1.55% by 2015; p < 0.001). More Appalachians received cessation treatment than non-Appalachians in 2013 (2.72% vs. 2.03%), but by 2015 non-Appalachians received more treatment overall (1.50% vs. 1.65%; p < 0.001). Appalachians received more counseling and NRT, but less varenicline, than non-Appalachians.

CONCLUSIONS

Utilization of all forms of tobacco cessation treatment throughout Kentucky, and particularly in rural Appalachia, remained limited despite Medicaid enrollment as well as coverage expansions. These findings suggest that barriers persist in access to tobacco cessation treatment for individuals in Medicaid.

The Prevalence of Multiple Comorbidities in Stroke Survivors in Rural Appalachia and the Clinical Care Implications

BACKGROUND

The majority of studies on multimorbidity have been in aging populations and there is a paucity of data on individuals following stroke.

OBJECTIVE

In order to better understand the overall complexity of the stroke population in rural Kentucky, we examined the prevalence of multimorbidity that impact the overall long-term health and health care for these individuals.

METHODS

A secondary analysis examined whether there are gender or age differences in this stroke population related to the prevalence of multimorbidity. A total of 5325 individuals, 18 years of age and older, seen at an academic medical center for the primary diagnosis of acute ischemic stroke or transient ischemic attack between the years of 2010-2017 were identified using the Kentucky Appalachian Stroke Registry. Descriptive analysis was used to report the prevalence of each comorbidity in the rural population by age group, gender, and level of multimorbidity by looking at concurrent frequencies.

RESULTS

Overall, hypertension, dyslipidemia, tobacco use, diabetes, and obesity were the comorbidities with the highest prevalence in our population irrespective of gender. Over 78% (n = 4153) of the individuals had 3 or more comorbidities while 61% (n = 3285) had at least 3 out of the top 5 comorbidities (hypertension, hyperlipidemia, tobacco, obesity, diabetes). With respect to age, 15% (n = 795) of the sample was under the age of 50, while 32% (n = 1704) were between the age of 50 and 64 and 53% (n = 2826) of the sample were 65 years or older.

CONCLUSIONS

The results of this study indicate the majority of individuals affected by stroke in rural Appalachia Kentucky have multimorbidity. In addition, almost half of these individuals are having their strokes at a younger age, which will require a shift in the focus for therapeutic interventions (eg, reintegration into the workforce versus just community reintegration).

Health Behaviors in Rural Appalachia

OBJECTIVES

To better understand the disproportionate burdens from cancer, cardiovascular disease, diabetes mellitus, stroke, and other chronic conditions related to energy balance, we studied diet and physical activity patterns in younger and older adults in rural Appalachia by using a nonclinical, cross-sectional, community-based sampling approach.

METHODS

A total of 651 younger (ages 18-59) and 254 older (ages ≥60) Appalachians were recruited from 43 churches or community organizations. Participants answered questions about fruit and vegetable intake and physical activity. Analyses were adjusted for clustering within churches.

RESULTS

Compared with older Appalachians, younger Appalachians consumed significantly fewer fruits and vegetables (P = 0.01) and reported significantly more moderate-to-vigorous physical activity (P = 0.01). Regardless of age, engagement in healthy behaviors was suboptimal and well below national averages.

CONCLUSIONS

This community-based sample demonstrated elevated behavioral risk factors that likely contribute to some of the nation's highest rates of premature mortality. Despite suboptimal dietary intake and physical activity, results indicate some potential leverage points between the generations that may be used to improve health. For example, the older generation could benefit from engaging with their younger relatives in physical activities while advocating for a better-rounded diet. Given traditions of intergenerational connectedness, mutual aid, and self-reliance, transmission of healthier behaviors across the generations may be beneficial in the rural Appalachian context.

Epidemiology and Implementation of Cancer Prevention in Disparate Populations and Settings

Successful cancer prevention strategies must be tailored to support usability. In this article, we will focus on cancer prevention strategies in populations that differ by race and ethnicity, place and location, sexual orientation and gender identity, and age by providing examples of effective approaches. An individual may belong to none of these categories, to all of these categories, or to some. This intersectionality of belonging characterizes individuals and shapes their experiences. Even within a category, broad diversity exists. Effective cancer prevention strategies comprehensively engage the community at multiple levels of influence and may effectively include lay health workers and faith-based cancer education interventions. Health system efforts that integrate cancer health with other health promotion activities show promise. At the individual physician level, culturally literate approaches have demonstrated success. For example, when discussing cancer screening tests with older adults, clinicians should indicate whether any data suggest that the screening test improves quality or quantity of life and the lag time to benefit from the screening test. This will allow older adults to make an informed cancer screening decision based on a realistic understanding of the potential benefits and risks and their values and preferences. Addressing individual and health system bias remains a challenge. Quality improvement strategies can address gaps in quality of care with respect to timeliness of care, coordination of care, and patient experience. The time is ripe for research on effective and interdisciplinary prevention strategies that harness expertise from preventive medicine, behavioral medicine, implementation science, e-health, telemedicine, and other diverse fields of health promotion.

Utilizing Multi-Theory Model in Determining Intentions to Smoking Cessation Among Smokers

Background:

Smoking is a risk factor for lung cancers, and a myriad of other acute and chronic ailments. The purpose of this study was to predict initiation and sustenance of smoking cessation among smokers using a fourth-generation behavioral framework, multi-theory model (MTM) of health behavior change.

Methods:

A convenience sample of smokers from a shopping mall in rural, Appalachian Kentucky county was invited to participate in this cross-sectional study. A 38-item, face and content validated, MTM-based survey instrument was administered to the participants.

Results:

A total of 148 participants completed the study. The mean age of the participants was 35.53 (SD = 14.52) years. Most were male (58.1%) and Caucasian (95.9%). Participants reported smoking for an average of 16.45 (SD = 13.12) years. Participatory dialogue (β = 0.235, P = .003) and behavioral confidence (β = 0.305, P = .005) were significant predictors of intention for initiation for smoking cessation behavior. Emotional transformation (β = 0.319, P = .001) was a significant predictor of intention for sustenance for smoking cessation behavior.

Discussion:

Two of the MTM constructs for initiation and one of the MTM constructs for sustenance of change accounted for a moderate amount of variance in initiation and sustenance of smoking cessation behavior among community members in a rural, Kentucky county. MTM has utility for predicting both initiation and sustenance of smoking cessation behavior. Future interventions using MTM constructs should be developed for smoking cessation behavior change.

Mountaintop removal mining and multiple illness symptoms: A latent class analysis

BACKGROUND

Mountaintop removal mining has been associated with multiple types of disease outcomes for populations living nearby. The current study tested whether latent classes identifying people with symptoms from multiple organ systems were associated with residence in mountaintop mining communities.

METHODS

We used data from three cross-sectional household community surveys conducted in three Appalachian states (N = 2756). The surveys contained information on 29 recent illness symptoms grouped into eight organ systems (respiratory, cardiovascular, gastrointestinal, musculoskeletal, skin, eye-ear-nose-throat, neurological, and other.) We identified latent classes, and then tested whether classes with higher probabilities of multiple symptoms would be associated with residence in mountaintop removal areas after control for covariates.

RESULTS

Three latent classes were identified, including a low-symptom referent class, an intermediate class, and a class with high symptom probability across organ systems. Controlling for covariates, latent classes characterized by intermediate and high multi-symptom probabilities were significantly associated with residence near mountaintop removal mining, with the highest odds ratio for the MTR versus control condition for the high multi-symptom group (OR = 2.17, 95% CI = 1.80-2.61).

CONCLUSIONS

Symptoms across multiple organ systems were related to residential proximity to mountaintop removal mining. Prior research has established multiple environmental contaminants related to mining that may contribute to poor population health through more than one exposure route or chemical of concern.

Cancer-Related Beliefs and Perceptions in Appalachia: Findings from 3 States

BACKGROUND

Appalachians experience increased rates of cancer incidence and mortality compared to non-Appalachians. Many factors may contribute to the elevated cancer burden, including lack of knowledge and negative beliefs about the disease.

METHODS

Three National Cancer Institute (NCI)-designated cancer centers with Appalachian counties in their respective population-based geographic service areas-Kentucky, Ohio, and Pennsylvania-surveyed their communities to better understand their health profiles, including 5 items assessing cancer beliefs. Weighted univariate and bivariate statistics were calculated for each of the 3 state's Appalachian population and for a combined Appalachian sample. Weighted multiple linear regression was used to identify factors associated with a cancer beliefs composite score. Data from the combined Appalachian sample were compared to NCI's Health Information National Trends Survey (HINTS).

RESULTS

Data from 1,891 Appalachian respondents were included in the analysis (Kentucky = 798, Ohio = 112, Pennsylvania = 981). Significant differences were observed across the 3 Appalachian populations related to income, education, marital status, rurality, perceptions of present income, and body mass index (BMI). Four of 5 cancer beliefs were significantly different across the 3 states. Education, BMI, perceptions of financial security, and Kentucky residence were significantly associated with a lower composite score of cancer beliefs. When comparing the combined Appalachian population to HINTS, 3 of 5 cancer belief measures were significantly different.

CONCLUSIONS

Variations in cancer beliefs were observed across the 3 states' Appalachian populations. Interventions should be tailored to specific communities to improve cancer knowledge and beliefs and, ultimately, prevention and screening behaviors.

Characterization of Squamous Cell Lung Cancers from Appalachian Kentucky

BACKGROUND

Lung cancer is the leading cause of cancer mortality in the United States (U.S.). Squamous cell carcinoma (SQCC) represents 22.6% of all lung cancers nationally, and 26.4% in Appalachian Kentucky (AppKY), where death from lung cancer is exceptionally high. The Cancer Genome Atlas (TCGA) characterized genetic alterations in lung SQCC, but this cohort did not focus on AppKY residents.

METHODS

Whole-exome sequencing was performed on tumor and normal DNA samples from 51 lung SQCC subjects from AppKY. Somatic genomic alterations were compared between the AppKY and TCGA SQCC cohorts.

RESULTS

From this AppKY cohort, we identified an average of 237 nonsilent mutations per patient and, in comparison with TCGA, we found that PCMTD1 (18%) and IDH1 (12%) were more commonly altered in AppKY versus TCGA. Using IDH1 as a starting point, we identified a mutually exclusive mutational pattern (IDH1, KDM6A, KDM4E, JMJD1C) involving functionally related genes. We also found actionable mutations (10%) and/or intermediate or high-tumor mutation burden (65%), indicating potential therapeutic targets in 65% of subjects.

CONCLUSIONS

This study has identified an increased percentage of IDH1 and PCMTD1 mutations in SQCC arising in the AppKY residents versus TCGA, with population-specific implications for the personalized treatment of this disease.

IMPACT

Our study is the first report to characterize genomic alterations in lung SQCC from AppKY. These findings suggest population differences in the genetics of lung SQCC between AppKY and U.S. populations, highlighting the importance of the relevant population when developing personalized treatment approaches for this disease.

The Kentucky Appalachian Stroke Registry (KApSR)

BACKGROUND

The population of rural Kentucky and West Virginia has a disproportionately high incidence of stroke and stroke risk factors. The Kentucky Appalachian Stroke Registry (KApSR) is a novel registry of stroke patients developed to collect demographic and clinical data in real time from these patients' electronic health records.

OBJECTIVE

We describe the development of this novel registry and test it for ability to provide the information necessary to identify care gaps and direct clinical management.

METHODS

The KApSR was developed as described in this article. To assess utility in patient care, we developed a "Diabetes Quality Assurance Dashboard" by cross-referencing patients in the registry with a diagnosis of ischemic cerebrovascular disease with patients that were tested for hemoglobin A1c (HbA1c) levels, patients with HbA1c levels diagnostic for diabetes mellitus (DM), and patients with an elevated HbA1c that were formally diagnosed with DM.

RESULTS

For the 1008 patients treated for ischemic cerebrovascular disease in the year studied, 859 (85%) had their HbA1c tested. Of those, 281 had levels of 6.5 or greater, although only 261 (93%) were discharged with a formal diagnosis of DM.

CONCLUSIONS

The KApSR has practical value as a tool to assess a large population of patients quickly for care quality and for research purposes.

Widening Disparities In Infant Mortality And Life Expectancy Between Appalachia And The Rest Of The United States, 1990-2013

Appalachia-a region that stretches from Mississippi to New York-has historically been recognized as a socially and economically disadvantaged part of the United States, and growing evidence suggests that health disparities between it and the rest of the country are widening. We compared infant mortality and life expectancy disparities in Appalachia to those outside the region during the period 1990-2013. We found that infant mortality disparities widened for both whites and blacks, with infant mortality 16 percent higher in Appalachia in 2009-13, and the region's deficit in life expectancy increased from 0.6 years in 1990-92 to 2.4 years in 2009-13. The association between area poverty and life expectancy was stronger in Appalachia than in the rest of the United States. We found wide health disparities, including a thirteen-year gap in life expectancy among black men in high-poverty areas of Appalachia, compared to white women in low-poverty areas elsewhere. Higher mortality in Appalachia from cardiovascular diseases, lung cancer, chronic lower respiratory diseases or chronic obstructive pulmonary disease, diabetes, nephritis or kidney diseases, suicide, unintentional injuries, and drug overdose contributed to lower life expectancy in the region, compared to the rest of the country. Widening health disparities were also due to slower mortality improvements in Appalachia.

Beliefs About Behavioral Determinants of Obesity in Appalachia, 2011-2014

The populations of many Appalachian communities have high rates of unhealthy body weight. This study aimed to identify differences in beliefs about obesity between Appalachians and non-Appalachians. Our analyses explored health beliefs and behaviors among US adults aged ≥18 (n = 14 451) who responded to the Health Information National Trends Survey (2011-2014), of whom 1015 (8%) resided within the 420 counties recognized as Appalachian by the Appalachian Regional Commission. Using weighted regression analyses and controlling for sociodemographic characteristics and general health, we determined that self-reported body mass index was higher among Appalachians than among non-Appalachians ( B = 0.75, P = .03, 95% confidence interval, 0.08-1.47) and that Appalachians were less likely than non-Appalachians to believe that lifestyle factors were related to obesity ( B = -0.37, P = .03, 95% confidence interval, -0.04 to -0.71). Results suggest that Appalachians may regard behavioral prevention differently from non-Appalachians, perhaps with less confidence in the effectiveness of certain behaviors to reduce obesity risk. Future research may determine whether such beliefs could complicate efforts to encourage healthy lifestyles throughout the region.

Living with traumatic brain injury in a rural setting: supports and barriers across the continuum of care

PURPOSE

Traumatic brain injury (TBI) is prevalent in Kentucky and comes with a high cost in care and quality of life for individuals and caregivers affected. Many people living with the condition of TBI have unmet needs. Research among people living with TBI in rural areas is limited. The purposes of this study were to (1) increase understanding of the lived experience of people with TBI and caregivers in rural regions of Kentucky across the continuum of their care and (2) provide their perspectives on barriers and facilitators of optimal function and well-being.

METHODS

A qualitative descriptive interview study was conducted by a multidisciplinary team. Content analysis was completed with data-derived coding and iterative modifications to analysis, coalescing codes into categories and themes.

RESULTS

Thirteen people with TBI and six caregivers participated in the interview. Categories that emerged in analysis included the experiences under each locus of care; themes included relationships, functional competence, and participation in meaningful activity.

CONCLUSION

Relationships represented both barriers and facilitators of well-being. Major unmet needs persisted in terms of medical problems, support for caregivers, community linkages, and participation in meaningful activities. Recommendations are made regarding avenues for addressing unmet needs. Implications for Rehabilitation People with TBI are living with chronic conditions and may need intensive rehabilitation after the injury and intermittent rehabilitation throughout life to develop and maintain functional competence. Rehabilitation providers need to understand the unique aspects of the rural home environment to which a patient will be discharged (e.g., mountainous terrain, lack of transportation, dimensions of home) and communicate with rural providers directly. Rehabilitation providers need additional focus on improving patient's and caregiver's abilities to advocate for themselves. Patients with TBI should be referred to vocational rehabilitation as soon as possible to make the transition to meaningful activity at home more of a possibility.

Associations of smoking with overall obesity, and central obesity: a cross-sectional study from the Korea National Health and Nutrition Examination Survey (2010-2013)

OBJECTIVES

The association between smoking and obesity is a significant public health concern. Both are preventable risk factors of cardiovascular disease and a range of other conditions. However, despite numerous previous studies, no consensus has emerged regarding the effect of smoking on obesity. We therefore carried out a novel study evaluating the relationship between smoking and obesity.

METHODS

A total of 5,254 subjects aged 19 years or older drawn from the 2010-2013 Korea National Health and Nutrition Examination Survey were included in this cross-sectional study. Smoking was examined both in terms of smoking status and the quantity of cigarettes smoked by current smokers. Multiple logistic regression analysis was used to assess the association between smoking and obesity. Overall obesity was defined as a body mass index (BMI) ≥25 kg/m(2), and central obesity was defined as a waist circumference ≥90 cm for males and ≥85 cm for females. We adjusted for the possible confounding effects of age, sex, physical activity, alcohol consumption, and the presence of hypertension or diabetes.

RESULTS

A statistically significant difference in central obesity according to smoking status was identified. Current smokers were more likely to be centrally obese than never-smokers (adjusted odds ratio,1.30; 95% confidence interval, 1.02 to 1.67). However, no significant association was found between smoking and obesity defined by BMI. Moreover, among current smokers, no statistically significant association was found between the daily amount of smoking and obesity or central obesity.

CONCLUSIONS

Smoking was positively associated with central obesity. Current smokers should be acquainted that they may be more prone to central obesity.

Metabolic effects of smoking cessation

Smoking continues to be the leading cause of preventable death in the USA, despite the vast and widely publicized knowledge about the negative health effects of tobacco smoking. Data show that smoking cessation is often accompanied by weight gain and an improvement in insulin sensitivity over time. However, paradoxically, post-cessation-related obesity might contribute to insulin resistance. Furthermore, post-cessation weight gain is reportedly the number one reason why smokers, especially women, fail to initiate smoking cessation or relapse after initiating smoking cessation. In this Review, we discuss the metabolic effects of stopping smoking and highlight future considerations for smoking cessation programs and therapies to be designed with an emphasis on reducing post-cessation weight gain.
