Cost-effectiveness of Lifestyle Africa: an adaptation of the diabetes prevention programme for delivery by community health workers in urban South Africa

BACKGROUND

Lifestyle Africa is an adapted version of the Diabetes Prevention Program designed for delivery by community health workers to socioeconomically disadvantaged populations in low- and middle-income countries (LMICs). Results from the Lifestyle Africa trial conducted in an under-resourced community in South Africa indicated that the programme had a significant effect on reducing haemoglobin A1c (HbA1c).

OBJECTIVE

To estimate the cost of implementation and the cost-effectiveness (in cost per point reduction in HbA1c) of the Lifestyle Africa programme to inform decision-makers of the resources required and the value of this intervention.

METHODS

Interviews were held with project administrators to identify the activities and resources required to implement the intervention. A direct-measure micro-costing approach was used to determine the number of units and unit cost for each resource. The incremental cost per one point improvement in HbA1c was calculated.

RESULTS

The intervention equated to 71 United States dollars (USD) in implementation costs per participant and a 0.26 improvement in HbA1c per participant.

CONCLUSIONS

Lifestyle Africa reduced HbA1c for relatively little cost and holds promise for addressing chronic disease in LMIC. Decision-makers should consider the comparative clinical effectiveness and cost-effectiveness of this intervention when making resource allocation decisions.

Implementing text-messaging to support and enhance delivery of health behavior change interventions in low- to middle-income countries: case study of the Lifestyle Africa intervention

The prevalence of non-communicable diseases, such as diabetes and cardiovascular disease, is rising in low- and middle-income countries (LMICs). Health behavior change (HBC) interventions such as the widely used Diabetes Prevention Program (DPP) are effective at reducing chronic disease risk, but have not been adapted for LMICs. Leveraging mobile health (mHealth) technology such as text messaging (SMS) to enhance reach and participant engagement with these interventions has great promise, yet we lack evidence-informed approaches to guide the integration of SMS specifically to support HBC interventions in LMIC contexts. To address this gap, we integrated guidance from the mHealth literature with expertise and first-hand experience to establish specific development steps for building and implementing SMS systems to support HBC programming in LMICs. Specifically, we provide real-world examples of each development step by describing our experience in designing and delivering an SMS system to support a culturally-adapted DPP designed for delivery in South Africa. We outline eight key SMS development steps, including: 1) determining if SMS is appropriate; 2) developing system architecture and programming; 3) developing theory-based messages; 4) developing SMS technology; 5) addressing international SMS delivery; 6) testing; 7) system training and technical support; and 8) cost considerations. We discuss lessons learned and extractable principles that may be of use to other mHealth and HBC researchers working in similar LMIC contexts.Trial registration Clinicaltrials.gov, NCT03342274 .

Strengthening Tobacco 21 implementation and enforcement to reduce tobacco-related health disparities: A stakeholder engagement project

INTRODUCTION

As a part of a priority-setting stakeholder engagement project to strengthen the impact of the federal Tobacco 21 (T21) law, we conducted a qualitative study to solicit input from a nationwide sample of tobacco control stakeholders regarding the implementation, enforcement, and equity implications of the T21 law.

METHODS

Following the T21 policy evaluation guidance developed by the Centers for Disease Control (CDC), we identified T21 experts in four domains: policy, evaluation, subject matter, and implementation from a national search of stakeholders (invitations, n=1279) to account for geographical variation. This study presents results from five focus groups conducted in December 2021 among stakeholders (n=31) with experience in T21 policy, evaluation, subject matter, and implementation.

RESULTS

Participating T21 stakeholders reported on eight themes from four main topic areas: 1) Implementation, 2) Enforcement, 3) Equity outcomes, and 4) Recommended changes from stakeholders. Stakeholders shared insights on both passive and active implementation methods used in their communities, and highlighted major barriers such as the absence of a standardized tobacco retail licensing mandate and insufficient resources. Regarding T21 enforcement, stakeholders believed that current deterrents for retail violations might not be effective. They noted that vape and tobacco shops and online sales of tobacco products are emerging major challenges in T21 enforcement. Stakeholders also discussed possible health inequities that may be exacerbated by heterogenous implementation of the T21 law.

CONCLUSIONS

To strengthen T21 and mitigate potential exacerbation of existing health inequities, greater alignment of federal, state, and local efforts to reduce heterogeneity of implementation and enforcement of the T21 law is recommended.

The Effects of Opt-out vs Opt-in Tobacco Treatment on Engagement, Cessation, and Costs: A Randomized Clinical Trial

Importance

Tobacco use causes 7 million deaths per year; most national guidelines require people who use tobacco to opt in to care by affirming they are willing to quit. Use of medications and counseling is low even in advanced economy countries.

Objective

To evaluate the efficacy of opt-out care vs opt-in care for people who use tobacco.

Design, Setting, and Participants

In Changing the Default (CTD), a Bayesian adaptive population-based randomization trial, eligible patients were randomized into study groups, treated according to group assignment, and debriefed and consented for participation at 1-month follow-up. A total of 1000 adult patients were treated at a tertiary care hospital in Kansas City. Patients were randomized from September 2016 to September 2020; final follow-up was in March 2021.

Interventions

At bedside, counselors screened for eligibility, conducted baseline assessment, randomized patients to study group, and provided opt-out care or opt-in care. Counselors and medical staff provided opt-out patients with inpatient nicotine replacement therapy, prescriptions for postdischarge medications, a 2-week medication starter kit, treatment planning, and 4 outpatient counseling calls. Patients could opt out of any or all elements of care. Opt-in patients willing to quit were offered each element of treatment described previously. Opt-in patients who were unwilling to quit received motivational counseling.

Main Outcomes and Measures

The main outcomes were biochemically verified abstinence and treatment uptake at 1 month after randomization.

Results

Of a total of 1000 eligible adult patients who were randomized, most consented and enrolled (270 [78%] of opt-in patients; 469 [73%] of opt-out patients). Adaptive randomization assigned 345 (64%) to the opt-out group and 645 (36%) to the opt-in group. The mean (SD) age at enrollment was 51.70 (14.56) for opt-out patients and 51.21 (14.80) for opt-out patients. Of 270 opt-in patients, 123 (45.56%) were female, and of 469 opt-out patients, 226 (48.19%) were female. Verified quit rates for the opt-out group vs the opt-in group were 22% vs 16% at month 1 and 19% vs 18% at 6 months. The Bayesian posterior probability that opt-out care was better than opt-in care was 0.97 at 1 month and 0.59 at 6 months. Treatment use for the opt-out group vs the opt-in group was 60% vs 34% for postdischarge cessation medication (bayesian posterior probability of 1.0), and 89% vs 37% for completing at least 1 postdischarge counseling call (bayesian posterior probability of 1.0). The incremental cost-effectiveness ratio was $678.60, representing the cost of each additional quit in the opt-out group.

Conclusions and Relevance

In this randomized clinical trial, opt-out care doubled treatment engagement and increased quit attempts, while enhancing patients' sense of agency and alliance with practitioners. Stronger and longer treatment could increase cessation.

"I'm a transgender man… I have to quit smoking for treatment and surgery": Describing the experience of a Latino transgender man during his attempt to quit smoking

OBJECTIVE

To describe the experience of a Latino transgender man during his attempt to quit smoking using a text messaging intervention.

METHODS

A Latino transgender man enrolled in a smoking cessation randomized controlled trial for Latino smokers. The participant was randomized to Decídetexto, a smoking cessation mobile intervention. The participant received a 24-week text messaging intervention. We assessed text messaging interactivity with the program, satisfaction, and self-reported abstinence at Week 12 and Month 6.

RESULTS

During the 24-week intervention period, the participant sent a total of 287 text messages to the program. When analyzing the content of the text messages sent by the participants, four important themes were identified: 1) gender identity, 2) low social support, 3) stressors (e.g., gender dysphoria), and 4) gender affirmation surgery as a reason to quit smoking. At both Week 12 and Month 6, the participant reported being extremely satisfied with the intervention and self-reported cigarette use.

CONCLUSION

A smoking cessation mobile intervention generated high satisfaction and frequent interactivity among a Latino transgender man. This case report provides important insights into the experience of one Latino transgender man during his attempt to quit smoking. There is an urgent need to develop or adapt existing smoking cessation interventions to better meet the needs of transgender people.

COVID-19 Testing in African American Churches Using a Faith-Health- Academic Partnership

Increasing access to COVID-19 testing in influential, accessible community settings is needed to address COVID-19 disparities among African Americans. We describe COVID-19 testing intervention approaches conducted in Kansas City, Missouri, African American churches via a faith-health-academic partnership. Trained faith leaders promoted COVID-19 testing with church and community members by implementing multilevel interventions using a tailored toolkit and standard education information. The local health department conducted more than 300 COVID-19 tests during or after Sunday church services and outreach ministry activities. (Am J Public Health. 2022;112(S9):S887-S891. https://doi.org/10.2105/AJPH.2022.306981).

Shared Decision Making in Health Care: Theoretical Perspectives for Why It Works and For Whom

Applying both theoretical perspectives and empirical evidence, we address 2 key questions regarding shared decision making (SDM): 1) When should SDM be more patient driven, and when should it be more provider driven? and 2) Should health care providers match their SDM style/strategy to patient needs and preferences? Self-determination theory, for example, posits a distinction between autonomy and independence. A patient may autonomously seek their health care provider's input and guidance, perhaps due to low perceived competence, low coping resources, or high emotional arousal. Given their need state, they may autonomously require nonindependence. In this case, it may be more patient centered and need supportive to provide more provider-driven care. We discuss how other patient characteristics such as personality attributes, motivational state, and the course of illness and other parameters such as time available for an encounter may inform optimal provider decision-making style and strategy. We conclude that for some types of patients and clinical circumstances, a more provider-driven approach to decision making may be more practical, ethical, and efficacious. Thus, while all decision making should be patient centered (i.e., it should consider patient needs and preferences), it does not always have to be patient driven. We propose a flexible model of SDM whereby practitioners are encouraged to tailor their decision making behaviors to patient needs, preferences, and other attributes. Studies are needed to test whether matching decision-making behavior based on patient states and traits (i.e., achieving concordance) is more effective than simply providing all patients with the same type of decision making, which could be tested using matching/mismatching designs.

Use of pre-enrollment randomization and delayed consent to maximize participation in a clinical trial of opt-in versus opt-out tobacco treatment

Background: Enrollment in smoking cessation trials remain sub-optimal. The aim of this analysis was to determine the effectiveness of a modified Zelen's design in engaging hospitalized patients who smoke in a pragmatic OPT-IN versus OPT-OUT tobacco treatment trial. Methods: At bedside, clinical staff screened smokers for eligibility, randomized eligible into study arms, and delivered the appropriate treatment approach. Study staff called randomized patients at one-month post-discharge, debriefed patients on the study design, and collected consent to participate. We used frequencies and percentages for categorical variables and means and standard deviations for quantitative variables to describe the characteristics of those who consented and were enrolled versus those who did not enroll. We also compared the characteristics of participants who consented and those who were reached and explicitly refused consent at one-month follow-up. We used the Cohen's d measure of effect size to evaluate differences. Results: Of the 1,000 randomized, 741 (74.1%) consented to continue in the study at one-month follow-up. One hundred and twenty-seven (12.7%) refused consent and 132 (13.2%) were unreachable. Cohen's d effect size differences between those who consented/enrolled (n = 741) and those who were not enrolled (n = 259) were negligible (<0.2) for age, gender, race/ethnicity, and most forms of insurance. The effect size was small for Medicaid (0.36), and other public insurance (0.48). After excluding those unreached at 1 month (12.7%), there were medium Cohen's d effect size differences between those who consented to participate (n = 741) and those who explicitly refused (n = 127) with respect to age (0.55) and self-pay or no insurance (0.51). There were small to negligible effect size differences with respect to sex, race/ethnicity, and other forms of health insurance. Conclusions: The modified Zelen's design resulted in successful enrollment of most participants who were initially randomized into the trial, including those not motivated to quit.

Trends in Adolescent Cannabis-Related Hospitalizations by State Legalization Laws, 2008-2019

PURPOSE

Adolescent cannabis use is associated with adverse health outcomes. The impact of cannabis legalization on adolescent cannabis-related hospitalizations remains unknown. We sought to assess whether state cannabis legalization is associated with adolescent cannabis-related hospitalizations.

METHODS

We conducted a retrospective cohort study of adolescent (11-17 years) hospitalizations at children's hospitals between January 1, 2008 and December 31, 2019 using the Inpatient Essentials database. We investigated differences in adolescent cannabis-related diagnosis during a hospitalization by state cannabis legalization status, including states with no legal use to medical cannabis laws (MCLs) and states with MCLs to nonmedical (>21 years old) cannabis laws (NMCLs).

RESULTS

Of 1,898,432 adolescent hospitalizations in 18 states and Washington, DC, there were 37,562 (2%) hospitalizations with a cannabis-related diagnosis, with 8,457 (23%) in states with no legal use, 20,444 (54%) in MCL states, and 8,661 (23%) in NMCL states. There was an increase in adjusted odds of a cannabis-related hospitalization in MCL (odds ratio 1.05, 95% confidence interval 1.04-1.06) and NMCL states (odds ratio 1.03, 95% confidence interval 1.02-1.03) between 2008 and 2019. Characteristics associated with the greatest increase in adjusted odds of a cannabis-related hospitalization postpolicy change included adolescents without an underlying mental health or other substance use disorder in MCL and NMCL states (p < .001) and younger age in NMCL states (13 vs. 16 and 17 years old, p = .02 and p = .02).

CONCLUSIONS

Cannabis-related adolescent hospitalizations at children's hospitals are increasing, with a disproportionate increase postlegalization in states with NMCLs. Interventions are warranted to increase cannabis use identification and treatment among at-risk adolescents in the hospital-based setting.

Effectiveness of Recruitment Strategies of Latino Smokers: Secondary Analysis of an mHealth Smoking Cessation Randomized Clinical Trial (Preprint)

Background

Latinos remain disproportionately underrepresented in clinical trials, comprising only 2%-3% of research participants. In order to address health disparities, it is critically important to increase enrollment of Latino smokers in smoking cessation trials. There is limited research examining effective recruitment strategies for this population.

Objective

The purpose of this study was to compare the effectiveness of direct versus mass and high- versus low-effort recruitment strategies on recruitment and retention of Latino smokers to a randomized smoking cessation trial. We also examine how the type of recruitment might have influenced the characteristics of enrolled participants.

Methods

Latino smokers were enrolled into Decídetexto from 4 states—New Jersey, Kansas, Missouri, and New York. Participants were recruited from August 2018 until March 2021. Mass recruitment strategies included English and Spanish advertisements to the Latino community via flyers, Facebook ads, newspapers, television, radio, church bulletins, and our Decídetexto website. Direct, high-effort strategies included referrals from clinics or community-based organizations with whom we partnered, in-person community outreach, and patient registry calls. Direct, low-effort strategies included texting or emailing pre-existing lists of patients who smoked. A team of trained bilingual (English and Spanish) recruiters from 9 different Spanish-speaking countries of origin conducted recruitment, assessed eligibility, and enrolled participants into the trial.

Results

Of 1112 individuals who were screened, 895 (80.5%) met eligibility criteria, and 457 (457/895, 51.1%) enrolled in the trial. Within the pool of screened individuals, those recruited by low-effort recruitment strategies (both mass and direct) were significantly more likely to be eligible (odds ratio [OR] 1.67, 95% CI 1.01-2.76 and OR 1.70, 95% CI 0.98-2.96, respectively) and enrolled in the trial (OR 2.60, 95% CI 1.81-3.73 and OR 3.02, 95% CI 2.03-4.51, respectively) compared with those enrolled by direct, high-effort strategies. Among participants enrolled, the retention rates at 3 months and 6 months among participants recruited via low-effort strategies (both mass and direct) were similar to participants recruited via direct, high-effort methods. Compared with enrolled participants recruited via direct (high- and low-effort) strategies, participants recruited via mass strategies were less likely to have health insurance (44.0% vs 71.2% and 71.7%, respectively; P<.001), lived fewer years in the United States (22.4 years vs 32.4 years and 30.3 years, respectively; P<.001), more likely to be 1st generation (92.7% vs 76.5% and 77.5%, respectively; P=.007), more likely to primarily speak Spanish (89.3% vs 65.8% and 66.3%, respectively), and more likely to be at high risk for alcohol abuse (5.8 mean score vs 3.8 mean score and 3.9 mean score, respectively; P<.001).

Conclusions

Although most participants were recruited via direct, high-effort strategies, direct low-effort recruitment strategies yielded a screening pool more likely to be eligible for the trial. Mass recruitment strategies were associated with fewer acculturated enrollees with lower access to health services—groups who might benefit a great deal from the intervention.

Feasibility and Effectiveness of Recruiting Latinos in Decídetexto-A Smoking Cessation Clinical Trial from an Emergency Department Patient Registry

There is an underrepresentation of Latinos in smoking cessation clinical trials. This study describes the feasibility and effectiveness of recruiting Latino smokers in the U.S. from an emergency department (ED) patient registry into a randomized smoking cessation clinical trial. Recruitment occurred from the Hackensack University Medical Center ED. Potential participants were contacted from a patient registry. The primary outcome was whether the participant responded to a call or text. Secondary outcomes included the best day of the week, week of the month, and time of day to obtain a response. Of the 1680 potential participants, 1132 were called (67.5%), while 548 (32.5%) were texted. For calls, response rate was higher compared to text (26.4% vs 6.4%; p < 0.001). More participants were interested in the study when contacted by calls compared to text (11.4% vs. 1.8%) and more participants were enrolled in the study when contacted by calls compared to text (1.1% vs. 0.2%). Regression models showed that ethnicity, age, time of day, and week of the month were not significantly associated with response rates. Recruitment of Latinos from an ED patient registry into a smoking cessation clinical trial is feasible using call and text, although enrollment may be low.

Brief Motivational Intervention to Improve Adolescent Sexual Health Service Uptake: A Pilot Randomized Controlled Trial in the Emergency Department

OBJECTIVE

To test the hypothesis that our motivational sexual health intervention (SexHealth) would increase health service uptake when compared with control.

STUDY DESIGN

In a randomized controlled trial at a pediatric emergency department, sexually active adolescents received either the SexHealth intervention or printed materials (control). SexHealth, delivered by a health educator, was a tablet-based, interactive intervention that included motivational techniques to promote sexual health, condom skills training, and tailored service recommendations. We assessed feasibility (eg, intervention completion, recommendations discussed, intervention duration), acceptability (ie, proportion enrolled and rating intervention as satisfactory), and efficacy; secondary outcomes were sexual and care-seeking behaviors at 6 months. The efficacy outcome was completion of ≥1 service at the index visit (ie, counseling, condoms, emergency contraception for immediate or future use, pregnancy/sexually transmitted infection/HIV testing, sexually transmitted infection treatment, and clinic referral).

RESULTS

We enrolled 91 participants (intervention = 44; control = 47). The intervention demonstrated high feasibility: 98% completed the intervention; 98% of recommendations were discussed; duration was 24.6 minutes, and acceptability: 87% of eligible adolescents enrolled and 93% rated the intervention as fairly to very satisfactory. Compared with controls, intervention participants were more likely to complete ≥1 service (98% vs 70%, P < .001) including HIV testing (33% vs 6%, P = .02) and emergency contraception (80% vs 0%, P = .01). There were no meaningful differences between arms in behaviors at follow-up.

CONCLUSIONS

SexHealth was feasible to implement, acceptable to youth, and resulted in increased uptake of health services during the emergency department visit. Additional strategies may be needed to extend intervention effects over time.

Adapting the Diabetes Prevention Program for low- and middle-income countries: preliminary implementation findings from lifestyle Africa

Rates of cardiovascular disease and diabetes are rising in low- and middle-income countries (LMIC), but there is a dearth of research devoted to developing and evaluating chronic disease interventions in these settings, particularly in Africa. Lifestyle Africa is a novel, culturally adapted version of the Diabetes Prevention Program (DPP) being evaluated in an ongoing community-based cluster-randomized trial in an underresourced urban community in South Africa. The purpose of this study is to describe the adaptations and adaptation process used to develop the program and to report preliminary implementation findings from the first wave of groups (n = 11; 200 individuals) who participated in the intervention. The RE-AIM model and community advisory boards guided the adaptation process. The program was designed to be delivered by community health workers (CHWs) through video-assisted sessions and supplemented with text messages. Participants in the trial were overweight and obese members of existing chronic disease "support groups" served via CHWs. Implementation outcomes included completion of sessions, session attendance, fidelity of session delivery, and participant satisfaction. Results indicated that 10/11 intervention groups completed all 17 core sessions. Average attendance across all sessions and groups was 54% and the percentage who attended at least 75% of sessions across all groups was 35%. Fidelity monitoring indicated a mean of 84% of all required procedures were completed while overall communication skills were rated as "good" to "excellent". These preliminary results support the feasibility of culturally adapting the DPP for delivery by CHWs in underresourced settings in LMIC.

Translation and Examination of the Reliability and Validity of the Spanish Version of the Smoking Self-Efficacy Questionnaire Among Latino Smokers

The 12-item Smoking Self-Efficacy Questionnaire (SEQ-12) is a valid and reliable instrument to assess confidence in one’s ability to refrain from smoking in a variety of different situations. This study evaluated the psychometric properties of the Spanish version of the 12-item Smoking Self-Efficacy Questionnaire (SEQ-12) among a sample of Spanish-speaking Latino smokers engaged in a smoking cessation research study. A forward-backward translation procedure guided the translation of the SEQ-12 into Spanish. The Spanish version of the SEQ-12 showed promising internal consistency reliability and construct validity among Latino smokers, with potential applications in both research and clinical settings.

Rural-Urban Differences in Changes and Effects of Tobacco 21 in Youth E-cigarette Use

BACKGROUND

The prevalence of current electronic cigarette (e-cigarette) use has increased dramatically among US youth. It is unknown how the impact of policies to curb e-cigarette use might differ across rural and urban areas.

METHODS

Data were collected from an annual statewide survey of middle and high school students in Kansas. Multivariable logistic regression was performed to examine the temporal change in current e-cigarette use in 2018 and 2019 across rural and urban areas and across the areas with and without a Tobacco 21 (T21) policy that raises the minimum age of tobacco sales to 21 years.

RESULTS

Of 132 803 participants, the prevalence of current e-cigarette use increased from 8.2% in 2018 to 12.6% in 2019. The increase was larger in rural areas (from 6.7% in 2018 to 13.4% in 2019, difference = 6.7%) than in urban areas (9.8%-11.9%, difference = 2.1%), with a significant interaction effect of year × urbanicity/T21 group (P < .0001). In urban areas, e-cigarette use increased significantly for middle school students in T21 areas (3.3%-4.5%; P = .01) and all students in non-T21 areas (8.1%-12.0%; P < .0001). In rural areas, the increase in e-cigarette use was significant in both T21 and non-T21 areas for all students, but the increase was smaller in T21 (7.9%-10.8%, difference = 3.0%) than in non-T21 areas (6.5%-13.7%, difference = 7.1%).

CONCLUSIONS

In this study, we reported marked disparities in the increase of youth e-cigarette use, with a larger recent increase in rural than in urban areas. T21 policies appear to mitigate these increases in both rural and urban youth.

Differential mechanisms of change in motivational interviewing versus health education for smoking cessation induction

Objective: To determine if Motivational Interviewing (MI) versus health education (HE) elicited different types of client language and whether these differences were associated with outcomes in a randomized clinical trial (RCT) for cessation induction among people who smoke with low motivation to quit. Methods: A secondary data analysis was conducted using data from the MI and HE arms of a trial in which people who smoke (N = 202) with low desire to quit were randomly assigned to four sessions of MI, HE or brief advice. Mediation analyses examined two types of client language: change talk (CT) and a novel form of client speech called "learning talk" (LT). Outcomes were assessed at baseline, 3 and 6 months. Results: With HE as the reference group, MI resulted in greater CT (OR = 3.0, 95% CI: 1.7-5.5) which was associated with better outcomes (average d = .34, SD = .13) and HE resulted in greater LT (OR = .05, 95% CI: .02-.10) which was also associated with better outcomes (average d = .42, SD = .08). Indirect parallel mediation effects on quit attempts were significant for both MI-CT (OR = 1.4, 95% CI: 1.1-1.7) and HE-LT (OR = .4, 95% CI: .2-.7). Conclusions: MI and HE were both efficacious via different pathways to change, confirming the utility of MI in this RCT as well as highlighting the potential of HE based on the "5R's" for smoking cessation. These findings emphasize the value of exploring theorized mechanisms of action of interventions evaluated in RCTs. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Changes in opioid prescriptions for Medicaid-enrolled children and young adults, 2012-2016

OBJECTIVES

To describe current trends in filled opioid prescriptions for Medicaid-enrolled children, adolescents and young adults (AYAs) from 2012 to 2016, and to identify patient characteristics and clinical settings associated with a higher probability of filled opioid prescriptions.

DESIGN

Retrospective cohort study of children and young adults enrolled in Medicaid from 2012 to 2016.

SETTING

10-12 states participating in the Medicaid Marketscan claims database.

PARTICIPANTS

Medicaid-enrolled children and young adults (0-21 years old).

EXPOSURE

Healthcare encounter(s) that could result in a new opioid prescription.

MAIN OUTCOME MEASURE

"Opioid visits," defined as healthcare encounters associated with a new opioid prescription filled within 7 days. Each opioid visit was assigned to the clinical provider most likely to have prescribed an opioid.

RESULTS

There were 113,068,027 visits among 4,427,838 Medicaid-enrollees and 1 percent (n = 1,130,006) of these were considered an opioid visit. Adjusted probabilities decreased from 1.2 percent to 0.8 percent from 2012 to 2016. The most frequently prescribed opioids were hydrocodone (48 percent; n = 653,011), codeine (23 percent; n = 305,644), and oxycodone (14 percent; n = 189,700); most of these were in combination with acetaminophen. The high-est adjusted percentages by clinical setting were seen in dental surgery (29 percent), outpatient surgery (21 percent), and inpatient (upon discharge, 10 percent).

CONCLUSIONS

Opioid prescriptions filled for Medicaid-enrolled children, adolescents, and young adults are relatively rare and adjusted probabilities decreased from 2012 to 2016. Among opioids filled, combination opioids and those with pedi-atric safety warnings remain commonly prescribed. Further research is critical to better understand drivers of prescribing practices and clinical indications for appropriate opioid use to inform improvements in pain management guidelines in this population.

Stress, Depression and Quit Attempt Outcomes among Unmotivated Smokers

INTRODUCTION

Stress and depressive symptoms have been linked to a reduced likelihood of sustaining smoking cessation. Because stress and depressive symptoms may negatively affect motivation to quit, stress and depression may also be important for whether or not smokers make a quit attempt.

OBJECTIVE

To examine the relationship between perceived stress and depressive symptoms and initiating a quit attempt in a smoking cessation induction trial.

METHODS

We conducted a secondary analysis of existing data from a randomized clinical trial (N = 255) comparing motivational interviewing to health education and brief advice for smoking cessation induction in smokers with low motivation to quit.

RESULTS

We observed positive associations between baseline predictors and quit attempts at week 12 (r = 0.192, p < 0.01 for depressive symptoms and r = 0.136, p < 0.05 for perceived stress). Logistic regression models revealed similar significant positive associations between baseline perceived stress and baseline depressive symptoms and making a quit attempt by week 12 (OR = 1.5, CI:1.03, 2.19 and OR = 1.03, 95% CI: 1.01, 1.06; respectively).

CONCLUSION

Unexpectedly, this study found generally small but consistently positive associations between baseline depressive symptoms and baseline perceived stress and making a quit attempt by week 12. The results can be viewed as encouraging in that interventions to encourage quit attempts do not appear counter-productive for individuals higher in stress and depressive symptoms, but these patients very likely will need additional supports to sustain abstinence.

Trends in Incidence of Nicotine Use Disorder Among Adolescents in the Pediatric Hospital, 2012-2019

OBJECTIVES

To assess trends in the incidence of nicotine use disorder (NUD) and describe associated factors among adolescents in the pediatric emergency department (ED) and inpatient settings.

METHODS

We conducted a retrospective cohort study of all adolescents (11-18 years) with a hospital encounter (inpatient, observation, or ED) in the Pediatric Health Information System between January 1, 2012, and September 30, 2019. After excluding adolescents with a previous International Classification of Diseases, Ninth Revision, and International Classification of Diseases, Tenth Revision, NUD diagnosis in the past 2 years, adolescents with new NUD diagnosis (ie, NUD incidence) were identified. A multivariable generalized liner mixed model was used to assess adjusted NUD incidence and investigate the relationship of NUD with patient characteristics and any interactions between characteristics and time. Spearman's correlation coefficient was used to assess the correlation between NUD incidence and e-cigarette use reported among youth.

RESULTS

Of 3 963 754 adolescents, 15 376 (0.4%) had a new diagnosis of NUD. Between 2012 and 2019, NUD incidence increased from 0.3% to 0.4% (P < .001). Findings from the time interaction effect analysis revealed increasing NUD incidence among certain subpopulations, including boys, those with a commercial or other insurance type, adolescents seen in the ED, those from the lowest and highest median household income quartile, and those in the South and West US Census regions. The correlation between NUD incidence and e-cigarette use among high school students was ρ = 0.884 (P = .006).

CONCLUSIONS

The incidence of NUD among adolescents is increasing. Efforts to increase the screening and treatment of NUD among adolescents in the hospital, particularly among the at-risk populations identified, are needed.

Barriers to Tobacco Cessation for Caregivers of Hospitalized Children: Perspectives of Pediatric Hospitalists

OBJECTIVES

Secondhand smoke exposure is associated with adverse health outcomes in children, yet tobacco cessation efforts for caregivers of hospitalized children are lacking. We sought to explore pediatric hospitalists' attitudes and barriers to providing tobacco cessation for caregivers of hospitalized children.

METHODS

We conducted a cross-sectional survey of pediatric hospitalists and fellows at 7 hospitals from November 1, 2018, to November 30, 2019. A 70-question anonymous survey was used to assess participants' perceptions of current practices, attitudes, and barriers to providing tobacco cessation support for caregivers of hospitalized children. We used descriptive statistics to summarize the data.

RESULTS

Of 207 eligible participants, 100 responded (48%). A majority (79%) agreed that offering tobacco cessation counseling for caregivers is an important part of their role in caring for hospitalized children, but 79% never received tobacco cessation training. Only half of the participants were comfortable providing brief advice and few were comfortable prescribing nicotine replacement therapy. Identified barriers included lack of time (74%), perceived lack of interest from patients' caregivers (71%), and other medical conditions of the patient taking priority (70%). The majority of participants were interested in further training in tobacco cessation support.

CONCLUSIONS

In this survey of 100 pediatric hospitalists, we found overall agreement that tobacco cessation support for caregivers of hospitalized children is important. However, most participants did not feel comfortable with provision of evidence-based counseling or pharmacotherapy because of identified barriers. Future work should target actionable barriers to improve provision of tobacco cessation support in this clinical setting.

Decídetexto: Mobile cessation support for Latino smokers. Study protocol for a randomized clinical trial

INTRODUCTION

Latinos, the largest minority group in the U.S., experience tobacco-related disparities, including limited access to cessation resources. Evidence supports the efficacy of mobile interventions for smoking cessation, which may be greater among Latinos, the highest users of text messaging.

OBJECTIVES

To describe the methodology of a randomized clinical trial to evaluate the impact of Decídetexto, a culturally appropriate mobile smoking cessation intervention versus standard care on smoking abstinence (cotinine-verified 7-day point prevalence abstinence) at Month 6 among Latino smokers.

METHODS

Latino smokers (N = 618) will be randomized to one of two conditions: 1) Decídetexto or 2) standard of care. Decídetexto is a mobile smoking cessation intervention (available in English and Spanish) that incorporates three integrated components: 1) a tablet-based software that collects smoking-related information to develop an individualized quit plan, 2) a 24-week text messaging counseling program with interactive capabilities, and 3) pharmacotherapy support. Decídetexto follows the Social Cognitive Theory as theoretical framework. Standard of care consists of printed smoking cessation materials along with referral to telephone quitline. Participants in both groups are given access to free pharmacotherapy (nicotine patches or gum) by calling study phone number. Promotores de Salud will rely on community-based approaches and clinical settings to recruit smokers into the study. All participants will complete follow-up assessments at Week 12 and Month 6.

DISCUSSION

If successful, Decídetexto will be ready to be implemented in different community- and clinic-based settings to reduce tobacco-related disparities.

A Multilevel Diabetes and CVD Risk Reduction Intervention in African American Churches: Project Faith Influencing Transformation (FIT) Feasibility and Outcomes

Wide-reaching health promotion interventions are needed in influential, accessible community settings to address African American (AA) diabetes and CVD disparities. Most AAs are overweight/obese, which is a primary clinical risk factor for diabetes/CVD. Using a faith-community-engaged approach, this study examined feasibility and outcomes of Project Faith Influencing Transformation (FIT), a diabetes/CVD screening, prevention, and linkage to care pilot intervention to increase weight loss in AA church-populations at 8 months. Six churches were matched and randomized to multilevel FIT intervention or standard education control arms. Key multilevel religiously tailored FIT intervention components included: (a) individual self-help materials (e.g., risk checklists, pledge cards); (b) YMCA-facilitated weekly group Diabetes Prevention Program (DPP) weight loss classes; (c) church service activities (e.g., sermons, responsive readings); and (d) church-community text/voice messages to promote healthy eating and physical activity. Health screenings (e.g., weight, blood pressure, blood glucose) were held during church services to identify participants with diabetes/CVD risks and refer them to their church's DPP class and linkage to care services. Participants (N = 352 church members and community members using churches' outreach ministries) were primarily female (67%) and overweight/obese (87%). Overall, FIT intervention participants were significantly more likely to achieve a > 5 lb weight loss (OR = 1.6; CI = 1.24, 2.01) than controls. Odds of intervention FIT-DPP participants achieving a > 5 lb weight loss were 3.6 times more than controls (p < .07). Exposure to sermons, text/email messages, brochures, commitment cards, and posters was significantly related to > 5 lb. weight loss. AA churches can feasibly assist in increasing reach and impact of diabetes/CVD risk reduction interventions with intensive weight loss components among at risk AA church-populations.

Fidelity of motivational interviewing training for dental hygiene students

Use of Motivational Interviewing (MI), a patient centered counseling strategy in the health professions, has demonstrated efficacy. Given the varied training associated with the delivery of health interventions, it is essential adherence and competence are equivocally assured. Motivational Interviewing Treatment Integrity (MITI) coding evaluated our recorded standardized patient oral assessment and planning sessions to identify the skills in which MI-trained students (n = 26) performed compared to student counterparts (n = 24) not trained in the MI curriculum. The full integration of MI in those receiving the MI curriculum resulted in the dental hygiene students with higher ratings for all global ratings, behavioral counts, and summary scores. MI-trained mean scores for evocation, collaboration, autonomy support, empathy, and direction ranged from 4.16(±0.43) to 3.85 (±0.67). All students receiving MI training reached competence in all 5 of the referenced MITI global variables: evocation, collaboration, autonomy support, empathy, and direction. The most substantial improvements for MITI behavioral and summary variables were in Giving Information, MI Adherence, and proportion of Open-Ended Questions. Complex Reflections, and subsequently Ratios of Complex Reflections to Open-Ended Questions were notably below proficiency in the MI group. Knowing which elements were adhered to well and which were lacking helps inform student MI learning outcomes. Results inform the design of MI training curricula to address areas of weakness and maximize performance across all MI fidelity domains.

Retail violations of sales to minors on e-cigarettes and cigars

OBJECTIVES

The finalized 'Deeming Rule' extended the Food and Drug Administration (FDA) authority to regulate e-cigarettes, cigars, and other newly deemed tobacco products. We seek to assess the neighborhood characteristics associated with retail violations of sales to minors (RVSM) by tobacco product.

STUDY DESIGN

We collected national inspection data on tobacco retailers during August 8, 2016, and May 31, 2018, from the FDA compliance check database.

METHODS

A web scraping tool was applied to text mine the FDA decision letters and extract information on the tobacco product involved in RVSM. Separate logistic regression models with random effects were performed to examine the association between zip code-level neighborhood characteristics and RVSM by tobacco product.

RESULTS

Of 268,317 minor-involved compliance inspections, 35,403 (13.2%) were identified as RVSM. Among 23,352 warning letters included in the final analysis, e-cigarettes, cigars, cigarettes, and smokeless tobacco accounted for 20.0% (n = 4673), 40.4% (9439), 35.6% (8303), and 4.0% (937) of RVSM, respectively. Flavored tobacco products were abundant among underage sales. For e-cigarettes, RVSM were more likely to occur in zip codes with a larger proportion of youth population aged 10-17 years (adjusted odds ratio [AOR] = 1.17 [1.02-1.34]). A larger proportion of African Americans was associated with a higher risk of RVSM for cigars (AOR = 1.09 [1.07-1.11]) but a lower risk of RVSM for e-cigarettes (AOR = 0.90 [0.87-0.93]).

CONCLUSIONS

Retail violations of underage sales for cigars and e-cigarettes are prevalent and neighborhood characteristics associated with violations differ by tobacco product. Continued inspections with tailored strategies to reduce RVSM of all tobacco products are needed.

Motivational Interviewing to Encourage Quit Attempts Among Smokers Not Ready to Quit: A Trial-Based Economic Analysis

INTRODUCTION

This study used data from a randomized controlled trial evaluating the efficacy of motivational interviewing (MI) relative to health education (HE) and brief advice (BA) to encourage quit attempts and cessation in order to determine their relative cost-effectiveness.

AIMS AND METHODS

Urban community residents (n = 255) with low desire to quit smoking were randomized to MI, HE, or BA which differed in communication style and/or number of treatment sessions. Incremental cost-effectiveness ratios were used to compare the intensive interventions (MI and HE) to BA for facilitating quit attempts and smoking cessation. Costs were calculated from the perspective of an agency that might engage in program delivery. Sensitivity analysis examined different assumptions for MI training and pharmacotherapy costs.

RESULTS

Total intervention delivery time costs per participant for MI, HE, and BA were $46.63, $42.87, and $2.4, respectively. Cost-effectiveness ratios per quit attempt at 24 weeks were $380 for MI, $272 for HE, and $209 for BA. The cost per additional quit attempt for MI and HE relative to BA was $508 and $301, respectively. The cost per additional quit for MI and HE relative to BA was $2030 and $752, respectively. Four separate sensitivity analyses conducted in our study did not change the conclusion the HE had a lower Incremental Cost-Effectiveness Ratio for both quit attempts and cessation.

CONCLUSIONS

HE was the most cost-effective of the three types of smoking cessation induction therapies and therefore may be preferable for smokers who are less motivated to quit. Providing valuable cost information in choosing different clinical methods for motivating smokers to quit.

IMPLICATIONS

All direct costs and activity-based time costs associated with delivering the intervention were analyzed from the perspective of an agency that may wish to replicate these strategies. A randomized controlled trial evaluating the efficacy of MI relative to HE and BA to encourage quit attempts and cessation determined their relative cost-effectiveness. HE was the most cost-effective of the three types of smoking cessation induction therapies and therefore may be preferable. Despite guideline recommendations, MI may not be the best approach to encourage quit attempts in diverse populations. Rather, a structured, intensive HE intervention might be the most cost-effective alternative.

Trial-by-Trial Fluctuations in Brain Responses to Stress Predict Subsequent Smoking Decisions That Occur Several Seconds Later

BACKGROUND

To investigate the neurobiological mechanisms that determine self-regulation of smoking urges when a person encounters stress, we investigated brain network interactions of smoking self-regulation by employing a real-time smoking (nicotine delivery) decision paradigm and a brain-as-predictor neuroimaging approach.

METHODS

While in the functional magnetic resonance imaging scanner, 25 cigarette smokers who abstained from smoking overnight made 200 real smoking decisions regarding whether or not to take a puff of an electronic cigarette during 3 different stress conditions (cognitive stress, emotional stress, and no stress). Cognitive stress was induced by a concurrent working memory load, and emotional stress was induced by manipulating a chance of aversive electric shock.

RESULTS

Behaviorally, both cognitive and emotional stress manipulations increased the probability of making a decision to smoke (i.e., taking a puff). In magnetic resonance imaging trial-by-trial analyses, the dorsolateral prefrontal cortex activity measured at the time of the stress cue significantly predicted future smoking decisions that occurred several seconds later. Furthermore, the influence of dorsolateral prefrontal cortex activity on smoking decisions was mediated by the ventral striatum activity at the time of smoking decisions.

CONCLUSIONS

Our study demonstrated that brain responses at the time of a stressful moment determine subsequent trial-by-trial smoking decisions by systematically altering brain executive (dorsolateral prefrontal cortex) and reward (ventral striatum) system network activities. Our results further suggest potential translational importance of neuroscientific approaches to predicting self-regulation failures at critical stressful moments.

Youth Knowledge of Tobacco 21 and its Association With Intention to Use Tobacco

Background

Raising the minimum legal age (MLA) of tobacco sales from 18 to 21 (Tobacco 21 [T21]) has recently been implemented nationwide as a method to reduce tobacco use, but empirical data on youth knowledge of T21 policies and related pathways to tobacco use are limited.

Methods

Data were collected from the 2018 Kansas Communities That Care Student Survey. Knowledge of the MLA was compared between T21 and non-T21 regions using a quasi-experimental design. Logistic regression and mediation analysis were conducted to assess the association between knowledge of the MLA, influencing factors, and intention to use tobacco.

Results

Of 16 949 students (aged between 11 and 18) completing the T21 survey, fewer students responded correctly about the MLA in T21 than in non-T21 regions (37.4% vs. 46.3% responded correctly, 27.6% vs. 24.2% responded incorrectly, respectively). In T21 regions, Hispanics and students who support T21 were more likely to respond correctly about the MLA. Among current non-tobacco users in T21 regions, students who responded correctly about the MLA were less likely to report intention to use tobacco (adjusted odds ratio [AOR] = 0.7, 95% confidence interval [CI]: [0.6–0.8]) than those who responded incorrectly. The pathway from knowledge of the MLA to intention to use tobacco was significantly mediated by increased support for T21 (p = .002), perceived difficulty in accessing cigarettes (p = .042), and reduced susceptibility to peer influence (p = .027).

Conclusions

Knowledge of the MLA was inversely associated with intention to use tobacco among youth. Educational campaigns to raise awareness and support for T21 among youth may improve the impact of T21 policies.

Implications

This study examined youth knowledge of the MLA to purchase tobacco products, and whether knowledge of the MLA was associated with reduced intention to use tobacco. It also examined other influencing factors (eg, perceived support for T21) and potential mediation pathways linking knowledge of the MLA with intention to use tobacco. Given the nationwide adoption of T21, educational campaigns to promote knowledge of the policy may improve its impact.

Feasibility and Acceptability of a Culturally- and Linguistically-Adapted Smoking Cessation Text Messaging Intervention for Latino Smokers

Objective: Assess the feasibility and acceptability of a culturally- and linguistically-adapted smoking cessation text messaging intervention for Latino smokers.

Methods: Using a community-based strategy, 50 Latino smokers were recruited to participate in a smoking cessation pilot study. Participants received a 12-week text messaging intervention and were offered Nicotine Replacement Therapy (NRT) at no cost. We assessed biochemically verified abstinence at 12 weeks, text messaging interactivity with the program, NRT utilization, self-efficacy, therapeutic alliance, and satisfaction.

Results: Participants were 44.8 years old on average (SD 9.80), and they were primarily male (66%) and had no health insurance (78%). Most of the participants were born in Mexico (82%) and were light smokers (1–10 CPD) (68%). All participants requested the first order of NRT, and 66% requested a refill. Participants sent an average of 39.7 text messages during the 12-week intervention (SD 82.70). At 12 weeks, 30% of participants were biochemically verified abstinent (88% follow-up rate) and working alliance mean value was 79.2 (SD 9.04). Self-efficacy mean score increased from 33.98 (SD 10.36) at baseline to 40.05 (SD 17.65) at follow-up (p = 0.04). The majority of participants (90.9%, 40/44) reported being very or extremely satisfied with the program.

Conclusion: A culturally- and linguistically-adapted smoking cessation text messaging intervention for Latinos offers a promising strategy to increase the use of NRT, generated high satisfaction and frequent interactivity, significantly increased self-efficacy, produced high therapeutic alliance, and resulted in noteworthy cessation rates at the end of treatment. Additional testing as a formal randomized clinical trial is warranted.

Opioid Use to Treat Migraine Headaches in Hospitalized Children and Adolescents

OBJECTIVES

Prescription of opioids to treat pediatric migraine is explicitly discouraged by treatment guidelines but persists in some clinical settings. We sought to describe rates of opioid administration in pediatric migraine hospitalizations.

METHODS

Using data from the Pediatric Health Information System, we performed a cross-sectional study to investigate the prevalence and predictors of opioid administration for children aged 7 to 21 years who were hospitalized for migraine between January 1, 2016, and December 31, 2018.

RESULTS

There were 6632 pediatric migraine hospitalizations at 50 hospitals during the study period, of which 448 (7%) had an opioid administered during the hospitalization. There were higher adjusted odds of opioid administration in hospitalizations for non-Hispanic black (adjusted odds ratio [aOR], 1.68; P < .001) and Hispanic (aOR, 1.54; P = .005) (reference white) race and ethnicity, among older age groups (18-21 years: aOR, 2.74; P < .001; reference, 7-10 years), and among patients with higher illness severity (aOR, 2.58; P < .001). Hospitalizations during which an opioid was administered had a longer length of stay (adjusted rate ratio, 1.48; P < .001) and higher 30-day readmission rate (aOR, 1.96; P < .001). By pediatric hospital, opioid administration ranged from 0% to 23.5% of migraine hospitalizations. Hospitals with higher opioid administration rates demonstrated higher adjusted readmission rates (P < .001) and higher adjusted rates of return emergency department visits (P = .026).

CONCLUSIONS

Opioids continue to be used during pediatric migraine hospitalizations and are associated with longer lengths of stay and readmissions. These findings reveal important opportunities to improve adherence to migraine treatment guidelines and minimize unnecessary opioid exposure, with the potential to improve hospital discharge outcomes.

Developing and Testing a Personalized, Evidence-Based, Shared Decision-Making Tool for Stent Selection in Percutaneous Coronary Intervention Using a Pre-Post Study Design

Background Drug-eluting stents reduce the risk of restenosis in patients undergoing percutaneous coronary intervention, but their use necessitates prolonged dual antiplatelet therapy, which increases costs and bleeding risk, and which may delay elective surgeries. While >80% of patients in the United States receive drug-eluting stents, less than a third report that their physicians discussed options with them. Methods and Results An individualized shared decision-making (SDM) tool for stent selection was designed and implemented at 2 US hospitals. In the postimplementation phase, all patients received the SDM tool before their procedure, with or without decision coaching from a trained nurse. All patients were interviewed with respect to their knowledge of stents, their participation in SDM, and their stent preference. Between May 2014 and December 2016, 332 patients not receiving the SDM tool, 113 receiving the SDM tool with coaching, and 136 receiving the tool without coaching were interviewed. Patients receiving the SDM tool + coaching, as compared with usual care, demonstrated higher knowledge scores (mean difference +1.8; P<0.001), reported more frequent participation in SDM (odds ratio=2.96; P<0.001), and were more likely to state a stent preference (odds ratio=2.00; P<0.001). No significant differences were observed between the use of the SDM tool without coaching and usual care. For patients who voiced a stent preference, concordance between stent desired and stent received was 98% for patients who preferred a drug-eluting stent and 50% for patients who preferred a bare metal stent. The SDM tool (with or without coaching) had no impact on stent selection or concordance. Conclusions An SDM tool for stent selection was associated with improvements in patient knowledge and SDM only when accompanied by decision coaching. However, the SDM tool (with or without coaching) had no impact on stent selection or concordance between patients' stent preference and stent received, suggesting that physician-level barriers to SDM may exist.

Race moderates the effects of Motivational Interviewing on smoking cessation induction

OBJECTIVE

Health disparities necessitate exploration of how race moderates response to smoking cessation treatment. Data from a randomized clinical trial of Motivational Interviewing (MI) for smoking cessation induction were used to explore differential treatment response between African American (AA) vs Non-Black (NB) smokers.

METHODS

Adult tobacco smokers (138 AA vs 66 NB) with low desire to quit were randomly assigned to four sessions of MI or health education (HE). Outcomes (e.g., quit attempts) were assessed 3- and 6-months.

RESULTS

There was evidence of a Race by Treatment interaction such that MI was less effective than HE in AA smokers. Mean Cohen's d for the interaction effect was -0.32 (95% CI [-0.44, -0.20]). However, the race interaction could be accounted for by controlling for baseline relationship status and communication preference (wants directive approach).

CONCLUSIONS

MI may be less effective for smoking cessation induction in AA vs NB smokers when compared to another active and more directive therapy. The differential response between races may be explained by psychosocial variables.

PRACTICE IMPLICATIONS

MI may not be an ideal choice for all African American smokers. Patients' relationship status and preference for a directive counseling approach might explain disparities in response to MI treatment.

Dietary Intake Among Church-Affiliated African Americans: The Role of Intentions and Beliefs

Diabetes and heart disease disproportionately burden African Americans, who tend to have worse nutritional intake than Whites. Many Black churches are influential institutions in the Black community, with potential to assist with promotion of healthy eating behaviors. The purpose of the current study was to use the Theory of Planned Behavior (TPB) to examine intention to eat a healthy diet and dietary behaviors among church-affiliated African Americans. It was hypothesized that TPB constructs would positively predict intention to eat a healthy diet and that intention to eat a healthy diet would be a predictor of fat and fruit and vegetable intake. It was also hypothesized that control beliefs would predict reduced fat intake and increased fruit and vegetable intake. Path analyses indicated behavioral, normative, and control beliefs were predictive of intention to eat a healthy diet. Intention to eat healthy was a significant predictor of dietary intake behaviors. These findings provide support for the use of the TPB in examining diet among church-affiliated African Americans. This study represents an opportunity to inform dietary interventions for the African American faith community.

Adapting the Diabetes Prevention Program for low and middle-income countries: protocol for a cluster randomised trial to evaluate 'Lifestyle Africa'

INTRODUCTION

Low and middle-income countries like South Africa are experiencing major increases in burden of non-communicable diseases such as diabetes and cardiovascular conditions. However, evidence-based interventions to address behavioural factors related to these diseases are lacking. Our study aims to adapt the CDC's National Diabetes Prevention Program (DPP) within the context of an under-resourced urban community in Cape Town, South Africa.

METHODS/ANALYSIS

The new intervention (Lifestyle Africa) consists of 17 weekly sessions delivered by trained community health workers (CHWs). In addition to educational and cultural adaptations of DPP content, the programme adds novel components of text messaging and CHW training in Motivational Interviewing. We will recruit overweight and obese participants (body mass index ≥25 kg/m²) who are members of 28 existing community health clubs served by CHWs. In a 2-year cluster randomised control trial, clubs will be randomly allocated to receive the intervention or usual care. After year 1, usual care participants will also receive the intervention and both groups will be followed for another year. The primary outcome analysis will compare percentage of baseline weight loss at year 1. Secondary outcomes will include diabetes and cardiovascular risk indicators (blood pressure, haemoglobin A1C, lipids), changes in self-reported medication use, diet (fat and fruit and vegetable intake), physical activity and health-related quality of life. We will also assess potential psychosocial mediators/moderators as well as cost-effectiveness of the programme.

ETHICS/DISSEMINATION

Ethical approval was obtained from the University of Cape Town and Children's Mercy. Results will be submitted for publication in peer-reviewed journals and training curricula will be disseminated to local stakeholders.

A religiously-tailored, multilevel intervention in African American churches to increase HIV testing: Rationale and design of the Taking It to the Pews cluster randomized trial

HIV continues to disproportionately impact African American (AA) communities. Due to delayed HIV diagnosis, AAs tend to enter HIV treatment at advanced stages. There is great need for increased access to regular HIV testing and linkage to care services for AAs. AA faith institutions are highly influential and have potential to increase the reach of HIV testing in AA communities. However, well-controlled full-scale trials have not been conducted in the AA church context. We describe the rationale and design of a 2-arm cluster randomized trial to test a religiously-tailored HIV testing intervention (Taking It to the Pews [TIPS]) against a standard information arm on HIV testing rates among AA church members and community members they serve. Using a community-engaged approach, TIPS intervention components are delivered by trained church leaders via existing multilevel church outlets using religiously-tailored HIV Tool Kit materials and activities (e.g., sermons, responsive readings, video/print testimonials, HIV educational games, text messages) to encourage testing. Church-based HIV testing events and linkage to care services are conducted by health agency partners. Control churches receive standard, non-tailored HIV information via multilevel church outlets. Secondarily, HIV risk/protective behaviors and process measures on feasibility, fidelity, and dose/exposure are assessed. This novel study is the first to fully test an HIV testing intervention in AA churches - a setting with great reach and influence in AA communities. It could provide a faith-community engagement model for delivering scalable, wide-reaching HIV prevention interventions by supporting AA faith leaders with religiously-appropriate HIV toolkits and health agency partners.

Identifying pathways to quitting smoking via telemedicine-delivered care

OBJECTIVE

A randomized controlled trial of quitline-like phone counseling (QL) versus telemedicine integrated into primary care (ITM) compared the effectiveness of these modalities for smoking cessation. Study design and components were based on self-determination theory (SDT). The purpose of this study was to test our SDT-based model in which perceived health care provider autonomy support, working alliance, autonomous motivation, and perceived competence were hypothesized to mediate the effects of ITM on smoking cessation.

METHOD

Rural smokers (n = 560) were randomized to receive 4 sessions over a 3-month period of either QL or ITM. Follow-up assessments were conducted at Months 3, 6, and 12. The primary outcome was biochemically verified 7-day point prevalence at 12 -months. Structural equation modeling with latent change scores was used for the analysis.

RESULTS

Participants in the ITM condition reported greater increases in perceived health care provider autonomy support (PAS) at end of treatment, which in turn was associated with enhanced perceived competence to quit smoking (PC). Increased PC was associated with a higher likelihood of cessation at 12-months. Mediation analysis demonstrated significant indirect effects, including a path from ITM to increases in PAS to increases in PC to cessation at 12-months (indirect effect = 0.0183, 95% confidence interval [.003, .0434]).

CONCLUSIONS

When integrated into primary care, ITM may influence smoking cessation by enhancing the extent to which smokers feel supported by their providers and thereby increase their perceived ability to quit. Findings suggest that locating tobacco treatment services in health care provider offices imparts a motivational benefit for cessation. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Discontinuing Treatment Against Medical Advice: The Role of Perceived Autonomy Support From Providers in Relapsing-Remitting Multiple Sclerosis

BACKGROUND

Long-term medication adherence is problematic among patients with chronic medical conditions. To our knowledge, this was the first study to examine factors associated with nonadherence among patients with relapsing-remitting multiple sclerosis who discontinue disease-modifying treatments against medical advice.

PURPOSE

To examine differences in perceived provider autonomy support between disease-modifying treatment-adherent relapsing-remitting multiple sclerosis patients and relapsing-remitting multiple sclerosis patients who discontinued disease-modifying treatments against medical advice.

METHODS

Self-report questionnaires and a neurologic exam were administered to demographically matched adherent (n = 50) and nonadherent (n = 79) relapsing- remitting multiple sclerosis patients from the Midwest and Northeast USA.

RESULTS

Adherent patients reported greater perceived autonomy support from their treatment providers, F(1, 124) = 28.170, p < .001, partial η2 = .185. This difference persisted after controlling for current multiple sclerosis healthcare provider, education, disease duration, Expanded Disability Status Scale, perceived barriers to adherence, and prevalence of side effects, F(1, 121) = 9.61, p = .002, partial η2 = .074. Neither depressive symptoms, F(1, 124) = 1.001, p > .05, partial η2 = .009, nor the occurrence of a major depressive episode, χ2(1, N = 129) = .288, p > .05, differed between adherent and nonadherent patients.

CONCLUSIONS

Greater perceived autonomy support from treatment providers may increase adherence to disease-modifying treatments among patients who discontinue treatment against medical advice. Results may inform interventions for patients who discontinue treatment against medical advice.

Feasibility and Outcomes of an HIV Testing Intervention in African American Churches

The updated National HIV/AIDS Strategy recommends widespread HIV education and testing and calls the faith community to assist in these efforts. Yet, limited information exist on church-based HIV testing interventions. This study examined feasibility and assessed HIV testing outcomes of Taking It to the Pews (TIPS), a multilevel HIV education and testing intervention. Four African American churches were matched and randomized to TIPS or a standard-information control arm. Intervention churches delivered the religiously-tailored TIPS Tool Kit, which included educational materials to individuals and ministry groups; pastoral activities (e.g., sermons preached, receipt of HIV testing role-modeled), responsive readings, and church bulletin inserts in church services; and HIV testing during church services and church outreach events. All churches delivered 2-3 tools/month and coordinated 3 HIV testing events. At 12 months, significant increases in receipt of HIV testing (59% vs. 42%, p = 0.008), and particularly church-based testing (54% vs. 15%, p < 0.001), relative to controls were found. TIPS has great potential to increase reach, feasibility, and impact of HIV testing in African American churches.

"Every day I think about your messages": assessing text messaging engagement among Latino smokers in a mobile cessation program

INTRODUCTION

Mobile health interventions are a promising mode to address tobacco-related disparities among Latinos, the largest minority group and the highest users of text messaging technology. The purpose of this pilot study was to assess engagement in a smoking cessation intervention delivered via text message (Kick Buts) among Latino smokers.

METHODS

We relied on a community-based recruitment strategy to enroll 20 Latino smokers in Kick Buts. Outcome measures included biochemically verified abstinence at 12 weeks, participant text messaging interactivity with the program, and satisfaction.

RESULTS

Participants' mean age was 40.7 years old (SD=14.6). Most of the participants were male (70%), did not have health insurance (75%), and reported low nicotine-dependence (60%). The majority of participants (75%) sent at least one text message to the program. On average, participants who interacted with the program sent 31.8 (SD=39.7) text messages. Eight themes were identified in participants' messages (eg, well-being, self-efficacy, strategies to quit, extra-treatment social support, etc). At 12 weeks, 30% of the participants were biochemically verified as abstinent.

CONCLUSION

A smoking cessation text message intervention generated high engagement among Latinos and resulted in noteworthy cessation rates. Future studies should assess the relationship of text messaging interactions with psychological effects (eg, intra-treatment social support, therapeutic alliance, and perceived autonomy support).

Reasons for nonadherence and response to treatment in an adherence intervention trial for relapsing-remitting multiple sclerosis patients

OBJECTIVES

To explore whether patients in an adherence trial who appeared not to take disease modifying therapy (DMT) for avoidance reasons could be reliably identified, by observational coding, for their main reason of not taking DMT. To determine whether reason groups could be distinguished by clinical and self-report psychological characteristics and intervention outcomes.

METHOD

Participants were multiple sclerosis patients (N = 78, 88.5% female, mean age 45.64) demotivated to take DMT. Audio recordings of the sessions were coded for the main reason of not taking DMT. Reason groups were compared based on patient characteristics and intervention outcomes.

RESULTS

Avoidance and three other reasons for not taking DMT (side effects, cost, and mild course) were reliably identified (κ = 0.88). Patient characteristics failed to distinguish participants in the Avoidance group, which also had poorer outcomes (X² [2, n = 73] = 6.35, p = 0.036).

CONCLUSIONS

Patients not taking DMT for avoidance reasons may need novel methods to identify them and encourage (re-)initiation.

Functional brain activation changes associated with practice in delaying smoking among moderate to heavy smokers: study protocol and rationale of a randomized trial (COPE)

BACKGROUND

Most smokers struggle to overcome tobacco addiction. Neuroscientific models of addiction emphasize the importance of brain regions associated with cognitive control and reward to understand the cycle of addiction and relapse. During an attempt at abstinence, the cognitive control system appears to be underpowered to override the heightened reward system of the addicted brain. Thus, one neural target for treatment is to strengthen the cognitive control system. It may be possible to improve the functioning of the cognitive control system via deliberate practice.

METHODS/DESIGN

This study will determine the effects of practicing delaying smoking on brain and behavioral measures of cognitive control. Smoking patterns will be monitored for 1 week and then smokers (N = 80) will be randomized to either practice cognitive control by delaying their first cigarette of the day for 2 weeks (practice group) or they will continue monitoring only (no practice group). Functional magnetic resonance imaging will be performed while smokers regulate their responses to smoking images (i) at baseline and (ii) after 2 weeks of practice (or no practice).

DISCUSSION

The primary aim of this study will be to identify the impact of practicing cognitive control on functional brain activation changes in response to smoking cues. If successful, this project will establish a neurobiological biomarker for increasing cognitive control and demonstrate the feasibility of neuroimaging methods to predict the efficacy of an intervention without a large clinical trial.

Probability discounting of treatment decisions in multiple sclerosis: associations with disease knowledge, neuropsychiatric status, and adherence

RATIONALE

Patients weigh risks and benefits when making treatment decisions. Despite this, relatively few studies examine the behavioral patterns underpinning these decisions. Moreover, individual differences in these patterns remain largely unexplored.

OBJECTIVES

The purpose of this study was to test a probability discounting model to explain the independent influences of risks and benefits when patients make hypothetical treatment decisions. Furthermore, we examine how individual differences in this probability discounting function are associated with patient demographics, clinical characteristics, disease knowledge, neuropsychiatric status, and adherence.

METHODS

Two hundred eight participants with relapsing-remitting multiple sclerosis (MS) indicated their likelihood (0-100%) of taking a hypothetical medication as the probability of mild side effects (11 values from .1 to 99.9%) and reported medication efficacies (11 values from .1 to 99.9%) varied systematically. They also completed a series of questionnaires and cognitive tests.

RESULTS

Individual components of medication treatment decision making were successfully described with a probability discounting model. High rates of discounting based on risks were associated with poor treatment adherence and less disease-specific knowledge. In contrast, high rates of discounting of benefits was associated with poorer cognitive functioning. Regression models indicated that risk discounting predicted unique variance in treatment adherence.

CONCLUSIONS

Insights gained from the present study represent an important early step in understanding individual differences associated with medical decision making in MS. Future research may wish to use this knowledge to inform the development of empirically supported adherence interventions.

The effects of assurances of voluntary compliance on retail sales to minors in the United States: 2015-2016

Multiple state attorneys generals have entered assurances of voluntary compliance (AVCs) with numerous national retail chains as an application of consumer protection laws to help prevent tobacco sales to minors. Little is known about the effectiveness of AVCs in reducing the violations of tobacco retailers for underage sales. We collected inspection data involving minors (n=53,832) on tobacco retailers in 2015 and 2016 from the Food and Drug Administration (FDA) compliance check database. Inspections on 13 national retail chains were classified into four categories: gas stations from oil companies, convenience stores, pharmacy stores, and supermarkets. Multilevel logistic regression models were performed to examine the effectiveness of AVCs, adjusted for state tobacco control policies, state youth smoking rates, and socio-economic status (SES) at census tracts. Overall the Retail Violation Rate for sales to minors (RVRm) significantly varied by retail category from 7.7% in pharmacy stores to 18.9% in gas stations from oil companies. Retailers that entered an AVC had lower odds of underage sales violations in convenience stores (aOR=0.75, 95% CI [0.61-0.93]) and supermarkets (aOR=0.74, 95% CI [0.59-0.93]). For gas stations from oil companies and pharmacy stores, there were no significant differences in RVRm between stores with an AVC and stores without an AVC. We found that entering into AVCs is associated with fewer retail violations of underage sales for convenience stores and pharmacy stores. Continued efforts to strengthen the enforcement of AVCs and to expand AVCs to more states and other retail chains may improve youth tobacco control.

Electronic Cigarettes and Future Marijuana Use: A Longitudinal Study

BACKGROUND

Cigarettes have been strongly associated with subsequent marijuana use among adolescents, but electronic cigarettes (e-cigarettes) are now rapidly replacing traditional cigarettes among youth. This study examines associations between youth e-cigarette use and subsequent marijuana use in a national sample.

METHODS

Youth (aged 12-17 years) never marijuana users at wave 1 (n = 10 364; 2013-2014) from the Population Assessment of Tobacco and Health study were followed-up in 1 year (wave 2, 2014-2015). Multivariable logistic regressions were performed to evaluate associations between e-cigarette use at wave 1 and ever/heavy marijuana use in the past 12 months (P12M) and at wave 2.

RESULTS

Among never marijuana users, e-cigarette ever use (versus never use) at wave 1 was associated with increased likelihood of marijuana P12M use (adjusted odds ratio [aOR] = 1.9; 95% confidence interval [CI]: 1.4-2.5) at wave 2. There was a significant interaction between e-cigarette use and age (P < .05) with aOR = 2.7 (95% CI: 1.7-4.3) for adolescents aged 12 to 14 and aOR = 1.6 (95% CI: 1.2-2.3) for adolescents aged 15 to 17. The association with heavy marijuana use was significant among younger adolescents (aOR = 2.5; 95% CI: 1.2-5.3) but was not among older adolescents. Heavier e-cigarette use at wave 1 yielded higher odds of P12M and heavy marijuana use at wave 2 for younger adolescents.

CONCLUSIONS

E-cigarette use predicts subsequent marijuana use among youth, with a stronger associations among young adolescents. Reducing youth access to e-cigarettes may decrease downstream marijuana use.

Two brief valid measures of therapeutic alliance in counseling for tobacco dependence

Behavioral counseling is effective for smoking cessation and the psychotherapy literature indicates therapeutic alliance is key to counseling effectiveness. However, no tobacco-counseling specific measures of alliance exist that are suitable in most tobacco counseling contexts. This hinders assessment of counseling components in research and clinical practice. Based on the Working Alliance Inventory, and external expert review, we developed two alliance instruments: the 12-item and 3-item Working Alliance Inventory for Tobacco (WAIT-12 and WAIT-3). Two samples of 226 daily smokers via Amazon Mechanical Turk completed measures including demographics, tobacco characteristics, working alliance scales, and quit attempts. Both WAIT-12 and WAIT-3 had good to excellent internal consistency (0.92 and 0.88 for the WAIT-3 and 0.96 for the WAIT-12). The WAIT-12 1-factor model indicated poor fit (CFI=0.83, TLI=0.79, RMSEA=0.19, SRMR=0.09). The WAIT-12 3-factor model (CFI=0.94, TLI=0.93, RMSEA=0.11, SRMR=0.04) was indicative of acceptable fit. Both the WAIT-12 and the WAIT-3 were significantly associated with participants' self-reported cigarettes per day, quit attempts, and cessation. Initial validation of the WAIT-12 and WAIT-3 indicates they are psychometrically sound measures of tobacco dependence counseling alliance. The WAIT-3 provides brevity; it can be administered in under 1min. The WAIT-12 allows for assessment of specific components of therapeutic alliance. Overall, these instruments should allow for better measurement of alliance in clinical services and research.

Implicit Attitudes and Smoking Behavior in a Smoking Cessation Induction Trial

INTRODUCTION

Although studies have suggested that implicit attitudes may predict smoking-related decisions, evidence that changes in implicit attitudes toward smoking are related to changes in smoking behavior is lacking. Using data from a trial comparing interventions to induce quit attempts among unmotivated smokers, this study examined whether changes in implicit attitudes were associated with quit attempts and cessation after controlling for explicit motivation.

METHODS

Daily smokers recruited from the community completed measures of implicit attitudes (Implicit Association Test) and explicit measure of motivation to smoke at baseline, mid-intervention (week 12 [W12]) and follow-up (week 26 [W26]). Quit attempts and cessation were assessed at follow-up, and cessation was biochemically verified.

RESULTS

As hypothesized, Implicit Association Test scores became more negative from baseline to W12, a change that was sustained at follow-up. Logistic regression analyses in which implicit attitudes were used to predict smoking outcomes revealed that negative changes in implicit attitudes from baseline to W12 and from baseline to W26 were significantly related to quit attempts (OR = 0.71, 95% CI [0.52, 0.97], p < .05 for both) independent of explicit motivation. Negative changes in implicit attitudes from baseline to W26 were significantly related to cessation (OR = 0.50, 95% CI [0.25, 1.00], p < .05).

CONCLUSIONS

Negative changes in implicit attitudes were associated with positive changes in smoking behavior independent of explicit motivation. This result indicates that smoking cessation interventions may be enhanced by incorporating strategies to change implicit attitudes, and that changes in implicit attitudes are also potentially important intervention outcomes.

IMPLICATIONS

Smoking cessation interventions may be improved by going beyond the current focus on explicit psychological constructs and targeting automatic cognitive processes such as implicit attitudes. The results are encouragement to examine how best to manipulate smokers' implicit attitudes as well as to determine the effect on their smoking behavior.
