Identifying Factors That Influence Physical Activity and Healthy Aging Among Older Latino Adults.

BACKGROUND: For older Latinos, some benefits of leisure-time physical activity (LTPA) include enhanced cognitive functioning, decreased loneliness, and reduced premature mortality. Despite LTPA benefits, adults ≥50 years are one of the most inactive age groups in the United States. METHODS: This qualitative study aimed to add to the limited evidence of LTPA in older Latino adults by exploring the barriers and facilitators for fitness class uptake and park use. Guided by a Social-Ecological Model of Health and Social Determinants of Health theoretical and a phenomenological research design, qualitative research data were collected via 27 personal interviews with Latino adults using a semistructured interview guide. Participants were recruited using purposive sampling strategies in collaboration with community partners. Bicultural data collectors conducted the semistructured interviews over Zoom. Thematic analysis was performed using Dedoose, following an inductive and deductive approach. RESULTS: The main barriers to fitness class attendance and park use were family and/or work commitments, perceived safety, and perceived discrimination. Conversely, the critical facilitators for participation were socialization into a group, social connectedness with group members, fitness instructor characteristics, and exercise history. CONCLUSIONS: Findings from this study hold important implications for the design of fitness programming and park-based recreation, including the need to increase the cultural diversity of recreation staff and culturally relevant programming. Future research is needed on time poverty related to family/work commitments and whether discriminatory practices at fitness centers, like ageism and race/ethnicity, influence physical activity behavior.

Supporting Peer Support Workers and Their Supervisors: Cluster-Randomized Trial Evaluating a Systems-Level Intervention.

OBJECTIVE: Peer support workers are a substantial and growing part of the mental health workforce. Because little research has investigated how to effectively support and supervise peer support workers, the authors evaluated the efficacy of a training program to strengthen the peer support workforce and the supervision of its workers. METHODS: Mental health services sites with peer support workers and supervisors in Los Angeles County were recruited for this cluster-randomized trial and 10-month follow-up. Of 348 peer support workers and 143 supervisors at 85 sites, 251 (72%) peer support workers and 115 (80%) supervisors completed baseline surveys. SHARE! the Self-Help And Recovery Exchange, a peer-run organization, delivered four training sessions on strategies to reduce stigma and to build an effective peer workforce, cultural competence, and a trauma-informed developmental model of supervision. Primary outcomes were peer-supportive organizational climate, mental health stigma, and peer support worker recovery. RESULTS: Intention-to-treat analyses indicated that sites receiving the training had significantly higher scores on peer-supportive organizational climate (Cohen's d=0.35, 95% CI=0.02-0.68, p=0.04) relative to sites not receiving the training. No significant differences were found between the two conditions for mental health stigma (Cohen's d=0.04) or peer support worker recovery (Cohen's d=0.14). CONCLUSIONS: The training had no impact on mental health stigma or peer support worker recovery. However, the findings suggest that the training increased the value organizations gave to peer support work, which may help improve peer support worker retention and outcomes among those served. Efforts to incorporate principles of the training into practice may strengthen outcomes.

Development and refinement of a corner-based injury prevention programme for Latino day labourers.

Objective: Latino day labourers (LDLs) in the USA are at increased risk for non-fatal and fatal occupational injuries, which are compounded by stressors that include wage theft, job insecurity and discrimination. This paper describes the development and refinement of Vales+Tú (You are Worthy of More), an injury prevention programme currently being evaluated as part of a cluster randomised trial in which health promotion is taken directly to the 'corners' (e.g. street corners, home improvement store parking lots, and public parks) where workers gather to seek employment. Design: Vales+Tú comprises two corner-based intervention approaches, group problem-solving (small group discussions) and brief motivational interviewing (one-on-one dialogue), that aim to activate LDL agency to control their safety and that of their peers. Setting: Corners in Houston, Texas, where LDLs seek employment. Method: Intervention Mapping informed the refinement of Vales+Tú for the current trial. We provide a narrative review of the development process based on needs assessment and formative development activities (surveys, focus group discussions and pilot tests). Results: In addition to documenting the need for LDL injury prevention, with 20.2%-41.6% of Houston-based LDLs surveyed between 2013-2014 and 2019 reporting a severe work-related injury in the past year, we describe key facets of the Vales+Tú corner-based intervention approaches - including their theoretical basis and LDL-centred activities, as well as enhancements made informed by formative evaluation. Conclusion: The community-engaged development process of Vales+Tú resulted in two practical intervention approaches that can be adopted by worker centres and other organisations to promote LDL worker safety.

Nutrition and Health Programming and Outreach in Grocery Retail Settings: A Community Coalition in Action.

Grocery stores can provide a conducive environment for interventions targeting healthy eating and access to health services, particularly in low-income communities. A wide array of organizations deliver nutrition and related programs in community settings, but rarely in a coordinated fashion. Collaboration of local health promotion organizations with grocery stores could increase consumers' access to and selection of healthy foods and related services. This evaluation of the In-Store Programming and Outreach Coalition (IPOC) uses thematic analysis of first-person accounts from coalition members. To our knowledge, this is the first study of such a coalition. We present perspectives from six stakeholders about the IPOC strengths, challenges, and recommendations for strengthening the delivery of in-store interventions. Themes identified include partnership, increased client reach and cross-referrals, conflicting work schedules, leadership, and recommendations to identify coalition leaders and expand services to other grocery stores. We conclude that grocery stores can offer a suitable setting for programming and community outreach through coalitions.

Vales+Tú: a cluster-randomized pilot study to reduce workplace injuries among US Latino day laborers.

Latino day laborers (LDL) are a vulnerable population of workers facing considerable risk for occupational injury. Under the guidance of our Community Advisory Board, we developed and tested the feasibility, acceptability and preliminary effects of Vales+Tú (You Are Worth More), a workplace injury risk-reduction program implemented by promotores on street-corners where LDL seek employment. The program was informed by theoretical perspectives emphasizing individual and group agency and self-determination. A pilot three-arm cluster-randomized community trial was conducted among 75 LDL. The intervention arms consisted of an individualized Brief Motivational Interview, a Group Problem Solving activity and a standard of care control (OSHA safety cards). We met our study goal of 25 LDL per intervention arm, and contacted 88% of participants post intervention. Participants evaluated the interventions favorably. At post-test, the Brief Motivational Interview group reported significant reductions in exposure to workplace hazards and increases in risk-reduction practices. The Group Problem Solving participants showed significant reductions in exposure to hazards (t-test -4.16, p < 0.001). Both intervention groups increased their reliance on corner peers, a measure of social support. Standard of care participants increased in self-efficacy to work safely. Overall, the only significant different between the three study conditions was in self-efficacy. These findings provide evidence of the feasibility and acceptability of Vales+Tú and show preliminary program efficacy. A large-scale replication trial will permit a more formal modeling of the study findings. Clinical Trial Registration (ClinicalTrials.gov): NCT04378348.

This pilot-randomized trial tested the feasibility and initial efficacy of an injury risk-reduction program among Latino day laborers (LDL). The study tested two alternative interventions consisting of a Brief Motivational Interview (Individual) and a Group Problem Solving (Group) conditions that were compared with a Standard-of-Care control group receiving safety cards. We then tested the extent to which the study conditions reduced exposure to workplace hazards and increased safety practices at work. Results indicate that intervening at day labor corners is a feasible intervention strategy acceptable to these immigrant workers. Initial results also indicate that there were multiple within-group significant differences in risk reduction, mostly in the individual condition, and that there was one significant between-group difference in safety self-efficacy at post-test. A larger more rigorous trial can further test the stability of these results and determine the extent to which these intervention approaches can reduce the risk for injury that LDL confront at work.

Predictors of e-cigarette initiation and use among middle school youth in a low-income predominantly Hispanic community.

Introduction: E-cigarette use among middle and high school youth increased from 2. 5 million in 2014 to 9.2 million in 2019, becoming the most common tobacco product used among youth. Hispanic youth, the largest ethnic minority in the United States, have higher rates of tobacco use, including e-cigarettes, than non-Hispanics. Identifying factors that put youth at risk for future e-cigarette use is vital to focusing prevention efforts. Informed by social cognitive theory, this study identifies predictors of e-cigarette uptake among e-cigarette naïve youth in a predominantly low-income Hispanic community. Methods: 1,249 students (6-8th grades) from two middle schools in El Paso, Texas consented to participate in this longitudinal survey during the 2016-2017 school year. The study sample for analysis was restricted to e-cigarette naïve students (n = 862). Outcome measures were e-cigarette initiation and current use at follow-up. Logistic regression models tested six hypotheses about predictors of e-cigarette initiation and current use: (1) intention, (2) outcome expectations, (3) knowledge, (4) friendship network exposure, (5) normative beliefs, and (6) social acceptability. Results: Among e-cigarette naïve students at baseline, 8% (n = 71) reported initiation at follow-up; of these, 3% (n = 23) reported current use. Significant predictors of initiation were intention (AOR = 2.46; 95% CI 1.69-3.59; p < 0.001), outcome expectations (AOR = 1.73; 95% CI 1.14-2.61; p = 0.009), friendship network exposure (AOR = 1.53; 95% CI 1.11-2.11; p =0.01), normative beliefs (AOR = 2.12; 95% CI 1.47-3.08; p < 0.001), and social acceptability (AOR = 1.91; 95% CI 1.28-2.85; p = 0.002). Significant predictors of current use were intention (AOR = 1.98; 95% CI 1.07-3.69; p = 0.03) and friendship network exposure (AOR = 1.69; 95% CI 1.06-2.70; p = 0.03). Conclusions: With the increasing popularity of e-cigarettes, age appropriate and culturally sensitive prevention strategies tailored at altering these predictive factors are essential in preventing future e-cigarette use.

Association Between Adverse Childhood Experiences, Resilience and Mental Health in a Hispanic Community.

This study explores the relations between adverse childhood experiences (ACEs), mental health and resilience among Hispanic adults living in the United States - Mexico Border region. Numerous studies have investigated the negative impact of ACEs on adult mental health, but the concept of resilience as a protective factor for mental health in the Hispanic communities has limited consideration in ACE treatment interventions. The proposed study addresses this gap in knowledge by investigating relations between ACEs, resilience, and mental health. An online survey was administered to 221 university students to assess the relationship between ACEs, mental distress and resilience. Using hierarchical linear regression, three models were estimated. First, including demographics, second including ACEs and low resilience, followed by the interaction of ACEs and resilience. Analyses indicate that ACEs were associated with mental distress (B = 1.02, 95% CI 0.37 - 1.68, p < 0.01) and low resilience was associated with mental distress (B = 5.37, 95% CI 3.15 - 7.59, p < .01). The interaction between ACEs and low resilience was also related to mental distress (B = 1.32, 95% CI 0.17 - 2.47, p = 0.03), indicating that ACEs had a larger association with mental distress among respondents with low resilience. Findings highlight the importance of the direct association between resilience and mental distress, along with the moderating influence of resilience on the relation between ACEs and mental health. Interventions promoting resilience may be effective in reducing mental distress, especially among individuals with a history of ACEs.

Initial conditions and functioning over time among community coalitions.

Developing operationally strong community coalitions is critical to actualizing their potential for public health improvement. The purpose of this study was to measure how substance use prevention coalitions in Mexico functioned across their first 1.5 years, and to test associations between initial community contextual factors and subsequent coalition functioning and outcomes. Members of 19 coalitions participated in three waves of surveys about coalition context and functioning. We used paired t-tests to assess changes in coalition functioning and outcomes. Regression models estimated associations between coalition functioning and outcomes and initial community context. Among coalition functioning factors, over coalitions' first 1.5 years, member engagement increased, as did coordinator skill and participatory leadership style. Two initial community context factors - community support for prevention and community champions - predicted several measures of process competence, but only community champions predicted perceived community improvement. Thus, community champions may play a pivotal role in later coalition success. The observed increases in member engagement and process competence may support subsequent coalition sustainability, a crucial component to realizing their potential impact on public health.

Evaluation of a novel mechanical compression device for hematoma prevention and wound cosmesis after CIED implantation.

BACKGROUND: An important complication of cardiac implantable electronic devices (CIED) implantation is the development of hematoma and device infection. OBJECTIVE: We aimed to evaluate a novel mechanical compression device for hematoma prevention and cosmetic outcomes following CIED implantation. METHODS: An open, prospective, randomized, single-center clinical trial was performed in patients undergoing CIED implantation. Patients were randomized to receive a novel mechanical compression device (PressRite, PR) or to receive the standard of care post device implantation. Skin pliability was measured with a calibrated durometer; the surgical site was evaluated using the Manchester Scar Scale (MSS) by a blinded plastic surgeon and the Patient and Observer Scar Scale (POSAS). Performance of PR was assessed through pressure measurements, standardized scar scales and tolerability. RESULTS: From the total of 114 patients evaluated for enrollment, 105 patients were eligible for analysis. Fifty-one patients were randomized to management group (PR) and 54 to the control group. No patients required early removal or experienced adverse effects from PR application. There were 11 hematomas (14.8% vs. 5.9% in the control and PR group respectively, p = NS). The control group had higher post procedure durometer readings in the surgical site when compared with the PR group (7.50 ± 3.45 vs. 5.37 ± 2.78; p = < .01). There were lower MSS scores in the PR group after 2 weeks (p = .03). CONCLUSION: We have demonstrated the safety of PR application and removal. In addition, PR appears to improve postoperative skin pliability, which could facilitate wound healing.

Addressing Hispanic Obesity Disparities Using a Community Health Worker Model Grounded in Motivational Interviewing.

PURPOSE: To determine whether Hispanic residents receiving the Healthy Fit intervention enhanced with Motivational Interviewing (MI) experienced greater improvements in body composition, relative to participants receiving the initial intervention. DESIGN: Quasi-experimental evaluation. SETTING: El Paso, Texas. SAMPLE: Among 656 baseline participants, 374 (54%) completed the 12-month assessment. INTERVENTION: In Healthy Fit, community health workers (CHWs) promote nutrition and exercise. To strengthen intrinsic motivation and help participants overcome barriers to change, we incorporated a 30-minute motivational interview into the baseline assessment. Follow-up phone calls at 1, 3, and 6 months were identical across conditions. MEASURES: CHWs assessed body mass index (BMI) and body fat percentage (BFP) using a bioelectrical impedance scale. ANALYSIS: Regression models estimated differences between intervention conditions on change in BMI and BFP from baseline to the 12-month assessment. RESULTS: Participants receiving MI had 2.13 times higher odds of losing weight (OR = 2.14, 95% CI [1.30, 3.53], P = .003) and 2.59 times higher odds of reduced BFP (OR = 2.59, 95% CI [1.51, 4.41], P < .001), relative to initial intervention participants. MI participants lost an average of 1.23 kg (2.71 lbs.) and their BFP declined 2% over 12 months. CONCLUSION: Findings suggest CHW use of MI is a promising approach for promoting incremental changes in diet and exercise, which Healthy Fit integrates into a low-cost intervention.

Protocol for a hybrid type 3 cluster randomized trial of a technical assistance system supporting coalitions and evidence-based drug prevention programs.

BACKGROUND: Over 5000 community anti-drug coalitions operating in the USA serve as a cornerstone of federal drug prevention. These coalitions, however, have demonstrated effectiveness in preventing substance use only when they use technical assistance (TA) and implement evidence-based programs (EBPs). The absence of TA and EBP implementation by coalitions is a key research-to-practice gap. The Coalition Check-Up TA system is designed to fill this gap by supporting community coalition implementation of EBPs. Existing TA models for evidence-based coalition approaches are resource intensive and coalition model specific. The Coalition Check-Up is a lower cost strategy that works with a variety of types of coalitions to support sustainable implementation of EBPs. This study protocol describes a hybrid type 3 effectiveness-implementation trial applying Wandersman's Interactive Systems Framework to test the effects of the Coalition Check-Up on coalition EBP implementation capacity and outcomes. The Interactive Systems Framework outlines how the prevention support system-especially TA-bolsters EBP dissemination and implementation. METHODS: Using a cluster randomized controlled design, this trial will test the overall effectiveness of the Coalition Check-Up, including how it contributes to EBP implementation and prevention of youth substance use. The first aim is to estimate the impact of the Coalition Check-Up on coalitions' capacity to do their work. We will recruit 68 anti-drug coalitions for random assignment to the Coalition Check-Up or "TA as usual" condition. We will evaluate whether the Coalition Check-Up improves coalition capacity using measures of coalition member responses about team processes, coalition network composition, and collaborative structure. Our second aim is to estimate the impact of the Coalition Check-Up on implementation of EBPs, and our third aim is to estimate the impact of the Coalition Check-Up on youth substance use. DISCUSSION: This project will clarify how the Coalition Check-Up, a scalable approach to TA due to its low cost, affects coalition capacity to support EBP implementation. Analyses also provide insight into causal pathways from the prevention support system to the prevention delivery system outlined by the Interactive Systems Framework. Results will build the evidence-base for how to support community coalitions' sustainable implementation of evidence-based prevention programs and policies.

Body composition outcomes of Healthy Fit and the role of acculturation among low-income Hispanics on the US-Mexico border.

BACKGROUND: Hispanic immigrants continue to experience higher rates of overweight and obesity compared to their non-Hispanic counterparts. Acculturation may contribute to unhealthy weight gain among immigrant populations by shifting dietary patterns from high fruit and vegetable consumption to unhealthier high fat diets. Healthy Fit, a culturally tailored community health worker (CHW) intervention, aims to reduce obesity related outcomes by providing physical activity and nutrition education and resources in a low-income Hispanic population. This study aims to evaluate outcomes of Healthy Fit participants and examine changes in body composition in relation to level of acculturation at baseline and follow-up. METHOD: In this longitudinal observational study, CHWs recruited 514 participants from community events and agencies serving low-income Hispanic populations in El Paso, Texas from 2015 to 2016. Following an in-person health screening, eligible participants received nutrition and physical activity education guided by fotonovelas, comic-like educational books. Telephone follow-ups made at 1, 3, and 6 months by CHWs encouraged follow-through on referrals. 288 participants completed the screening again during the 12-month follow-up. RESULTS: The sample was predominantly Hispanic (96%), female (82%), uninsured (79%), had a household income of less than $19,999 (70%), foreign-born (79%), preferred Spanish (86%) and few rated themselves as good or excellent for English proficiency (27%). Overall, Healthy Fit participants significantly improved (i.e., decreased) BFP by 0.71% (t = 2.47, p = 0.01) but not BMI (b = .01, t = - 0.14, p = .89). Contrary to expectations, acculturation was not associated with lower BMI (b = 0.09, p = 0.84) or BFP (b = 0.13, p = 0.85) at baseline. However, acculturation predicted changes in both BMI (b = 0.30, p = 0.03) and BFP (b = 1.33, p = 0 .01) from baseline to follow-up. Specifically, the low acculturation group improved in body composition measures over time and the high acculturation group did not improve in either measure. CONCLUSION: Findings suggest Healthy Fit was most effective among less acculturated individuals. The influence of acculturation on the efficacy of nutrition and exercise interventions suggests that Hispanics should not be treated as a homogenous subgroup.

Traffic-related air pollution reduction at UK schools during the Covid-19 lockdown.

Elevated urban Nitrogen Dioxide (NO2) is a consequence of road traffic and other fossil-fuel combustion sources, and the road transport sector provides a significant contribution to UK NO2 emissions. The inhalation of traffic-related air pollution, including NO2, can cause a range of problems to human health. Due to their developing organs, children are particularly susceptible to the negative effects of air pollution inhalation. Accordingly, schools and associated travel behaviours present an important area of study for the reduction of child exposure to these harmful pollutants. COVID-19 reached the UK in late January 2020. On the 23rd of March that year, the UK government announced a nationwide stay-at-home order, or lockdown, banning all non-essential travel and contact with people outside of their own homes. The lockdown was accompanied by the closure of schools, public facilities, amenities, businesses and places of worship. The current study aims to assess the significance of nationwide NO2 reductions at schools in England as a consequence of the lockdown in order to highlight the benefits of associated behavioural changes within the context of schools in England and potential child exposure. NO2 data were collected from all AURN (Automatic Urban and Rural Network) monitoring sites within 500 m of nurseries, primary schools, secondary schools and colleges in England. A significant reduction of mean NO2 concentrations was observed in the first month of the UK lockdown at background (-35.13%) and traffic (-40.82%) sites. Whilst lockdown restrictions are undoubtedly unsustainable, the study results demonstrate the possible reductions of NO2 at schools in England and potential reductions of child exposure that are achievable when public behaviours shift towards active travel, work from home policies and generally lower use of polluting vehicles.

Promoting Hispanic Immigrant Health via Community Health Workers and Motivational Interviewing.

Hispanic immigrant health disparities are among the highest in the nation, especially related to obesity and access to health services. Healthy Fit (En Forma Saludable) is a health promotion program that leverages public health department infrastructure to address these disparities through the use of three key innovations explored in this article: community health workers (CHWs), motivational interviewing (MI), and vouchers for free preventative health services. CHWs trained in MI conduct a health screening and then distribute preventive service vouchers and health resources as needed based on screening results. Vouchers cover breast, cervical, and colorectal cancer screening, and several vaccinations including flu and human papillomavirus. Resources to support exercise, to support a healthy diet, to quit smoking, and to reduce risky drinking are also distributed as needed. CHWs then use MI to address perceived barriers and strengthen intrinsic motivation to make use of the health resources. Integrating these strategies provides a low-cost approach to promote healthy behavior in an underserved immigrant population.

Documenting and Understanding Workplace Injuries Among Latino Day Laborers.

BACKGROUND: Latino day laborers face substantial injuries at work. We present a comprehensive assessment of their injury experience and explore the predictors of selfreported injuries. METHODS: Worker and injury characteristics were collected from 331 day laborers using an innnovative injury assessment tool. The odds of injury were estimated using a logistic regression. RESULTS: Participants were foreign-born, Spanish monolingual, and employed in construction. Sixty-seven individuals reported 88 past-year injuries, mostly involving the upper or lower extremities. Injuries were caused by moving heavy objects, falling, or being struck an object. Of the documented injuries, 24% were not reported at work due to fear of being fired; 64.4% resulted in missed workdays, 54.0% in temporary incapacitation, and 34.5% in permanent incapacitation. Being married significantly reduced the odds of reporting an injury. DISCUSSION: Better documentation can inform the development of better policy protections that ameliorate injuries experienced by Latino day laborers at the workplace.

Attitudes toward tobacco among low-income Hispanic adolescents: Implications for prevention.

Background: Although US cigarette smoking rates have steadily declined, the changing nature of nicotine consumption and the popularity of non-combustible nicotine products urges us to revise tobacco prevention strategies. Research on smoking perspectives among Hispanic youth is limited yet crucial for prevention efforts with Hispanics being the largest minority in the U.S.Objective: This study sought to understand the experience and perceptions of low-income Hispanic youth regarding tobacco use.Methods: Forty-nine adolescents (ages 9 to 19) from El Paso, Texas, participated in five extended focus group discussions about tobacco/nicotine use.Results: Adolescents were predominantly exposed to tobacco through relatives, although school and party contexts became more relevant as youth aged. Youth had negative perceptions of tobacco and smokers, but believed their peers often viewed tobacco positively. Youth also saw tobacco use as a functional stress-management strategy, especially within their extended family. Health and family were strong motivators not to smoke.Conclusions: Youth maintain several tensions in their views on tobacco. Tobacco use is considered unpleasant and harmful, yet youth perceive their peers to view it as cool. Peer to peer discussion of tobacco experiences and perceptions may help correct these incongruent viewpoints. Adding to this tension is the perception that tobacco is used to manage stress. Given the importance of the home environment for Hispanic youth, tobacco prevention efforts may benefit from engaging family to identify the ways in which tobacco use causes stress.

Cluster Randomized Trial of Teens Against Tobacco Use: Youth Empowerment for Tobacco Control in El Paso, Texas.

INTRODUCTION: This study examines smoke-free youth partnerships implementing the Teens Against Tobacco Use model developed by the American Lung Association. This innovative tobacco prevention strategy has not been evaluated rigorously. Students used peer teaching to educate youth about tobacco use and engaged in tobacco control advocacy activities. Participating high school and middle school youth were trained to develop and deliver tobacco prevention presentations to 4th-8th grade students in schools. STUDY DESIGN: To evaluate the efficacy of the presentations, matched pairs of classrooms willing to have 1 presentation were randomly assigned to receive either the presentation first (intervention condition) or later in the school year (control condition). SETTING/PARTICIPANTS: The study took place in a predominantly low-income Hispanic community. A total of 9 schools, 107 classes, and 2,257 students participated in the evaluation. MAIN OUTCOME MEASURES: Tobacco susceptibility was assessed with a brief survey administered to students in both intervention and control classrooms in 2014 and 2015 after the completion of presentations in intervention classrooms. Analyses completed in 2019 compared intervention and control classrooms on tobacco susceptibility. RESULTS: Intent-to-treat analyses indicated that classrooms receiving a tobacco prevention presentation had significantly lower tobacco susceptibility scores than classrooms that did not receive a presentation (12% vs 17%, p<0.01), representing a 37% reduction in the odds of tobacco susceptibility. Teens Against Tobacco Use presenters also completed tobacco retailer compliance checks and gained media coverage in advocating to regulate e-cigarettes in the same manner as other tobacco products. CONCLUSIONS: Findings suggest Teens Against Tobacco Use is an effective means of reducing tobacco susceptibility among 4th-8th graders in the immediate term. Longer-term outcome evaluations are needed to determine whether Teens Against Tobacco Use presentations can have a lasting impact on tobacco use. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT02443025.

Using a reasoned action approach to identify determinants of organized exercise among Hispanics: a mixed-methods study.

BACKGROUND: Research on Hispanics' activity preferences suggest that they prefer engaging in group-oriented physical activities, such as organized exercise. Yet, little is known about pathways to participation in organized exercise among Hispanics. This study used a reasoned action approach (RAA) framework to explore beliefs and determinants of organized exercise among Hispanics. Specifically, we examined the impact of participants' intentions on reported organized exercise behavior, and the relation between intentions and attitudes, subjective norms, perceived behavioral control, and self-efficacy. METHODS: Our mixed-methods study was part of a larger pre-post design intervention study. Participants completed an interview containing open- and closed-ended questions to identify salient beliefs and practices about attending organized exercise activities. We conducted two separate regression models to assess the effects of intentions on behavior (n = 330) and the associations of RAA constructs on intentions (n = 101), both adjusting for demographics. Qualitative analysis of a sub-sample (n = 105) of responses to open-ended questions identified salient beliefs related to organized exercise attendance. RESULTS: Our results showed that intentions predicted behavior at follow up (IRR = 2.03, p < .05), and that attitudes and perceived behavioral control were associated with intentions (ß = .36, p < .05; ß = .36, p <. 05, respectively). Qualitative findings suggest participants value health and the behavioral benefits of attending organized exercise activities; feel approval from family and friends; and identify transportation, time, distance, and costs as factors that influence their attendance to organized exercise activities. CONCLUSIONS: Consistent with theoretical expectations, we identified statistically significant determinants of intentions and attendance to organized exercise. Findings can inform the development of persuasive messages and interventions to promote exercise in low-income Hispanic populations facing obesity disparities.
