RESUMO

BACKGROUND: Women with higher body mass index report low rates of and face unique barriers to exercise. Increasing exercise participation can improve mental and physical health independent of weight loss; however, most exercise programs targeting this population focus predominately on losing weight. This paper aims to describe the development of Fit&Fab, a community-based exercise intervention focused on increasing exercise participation and enjoyment for women with obesity. METHODS: In partnership with the YMCA, we recruited women ages 35-64 years (body mass index ≥ 30) to participate in 4 focus groups to understand exercise preferences. Formative work was used to identify theory constructs and associated intervention components. Women from the focus groups were recruited for a community advisory board that finalized the intervention design, recruitment, and evaluation plan. RESULTS: Focus groups participants (N = 29) preferred to exercise without men and wanted a cohort-style class that included women of similar exercise levels and body types, incorporated social support, fun activities, and broke exercise into smaller bouts. They wanted a supportive instructor who was fit but understood weight-related challenges. The community advisory board and research team used focus group findings to inform design of the final intervention including group exercise classes, psychosocial support sessions, personalized training, exercise tracking, outcome monitoring, and rewards. CONCLUSIONS: Our findings emphasize the need to focus on exercise enjoyment and benefits other than losing weight to improve exercise participation among women with higher body mass index. In addition to having outcomes other than weight loss, exercise interventions with this population should also consider group composition, instructor, and class format.

RESUMO

Objectives: The Veggie Van model is a mobile market model that is efficacious in increasing fruit and vegetable consumption for lower-income participants. The model is currently being evaluated for its effectiveness in a multi-state trial. Preliminary implementation data, collected through process measures surveys and implementation interviews, indicate that there are several barriers to implementation among partner organizations and implementation fidelity to the Veggie Van model was low. Consideration and planning for implementation ought to occur early and often throughout the research process order to ensure Veggie Van model effectiveness. This paper describes the step-by-step process for creating strategies to enhance implementation of Veggie Van model components. Methods: Implementation mapping is a systematic process to develop implementation strategies through engagement with key stakeholders. We conducted a series of interviews (n = 31 representatives) with partner organizations (n = 8) to identify facilitators and barriers to Veggie Van model implementation. We then applied interview findings to an Implementation Mapping process to develop theory and practice-driven strategies to be integrated into existing implementation tools and technical assistance. Results: We identified implementation outcomes (e.g., staff implement the Veggie Van model component of nutrition education with fidelity) and performance objectives (e.g., offer nutrition education, in the form of food lessons and/or food demonstrations, at least bi-weekly) to achieve them. We conducted a secondary qualitative analysis of the findings from implementation interviews with partner organizations to identify behavioral determinants (e.g., attitudinal beliefs, social support) which were combined with the performance objectives to generate change objectives (e.g., view the Veggie Van model as advantageous to an organization and communities served). To achieve the change objectives, we developed implementation strategies that would be integrated into existing Veggie Van training resources including an online toolkit, webinars and trainings, an annual mobile market conference, and technical assistance. Conclusion: The development of theory and practice-driven implementation strategies will enable us to improve our implementation tools, thereby improving fidelity to the Veggie Van model among organizations and increasing the likelihood of its effectiveness. Detailing the design of a multifaceted implementation strategy using Implementation Mapping also provides a model to design similar strategies for other community-based interventions.

RESUMO

OBJECTIVE: To examine whether household type (eg, families with children) moderated the effects of an optimal defaults grocery intervention and examine intervention effects on grocery purchases to be consumed by the participant vs others in the household. METHODS: Participants (n = 65) diagnosed with or at risk for type 2 diabetes were recruited and randomized into an optimal default online grocery intervention or an online or in-person control group. Grocery receipt data were coded into Dietary Approaches to Stop Hypertension nutritional quality scores, and energy, carbohydrate, and sugar content were calculated. Repeated measures analysis of variance examined household types (eg, single vs multi-resident) as moderators of intervention effects. Parallel models explored foods purchased for the participant and foods purchased for other household members separately. RESULTS: Household type was not a significant moderator of intervention effects on nutritional quality or other nutrients of interest (P > 0.10). The default intervention significantly increased the nutritional quality of groceries purchased across household types and for other household members besides the participant (P < 0.05). CONCLUSIONS AND IMPLICATIONS: Optimal defaults may improve grocery purchases across different household types and extend to others in the household, supporting use across household types.

RESUMO

Ending the HIV epidemic in the United States will require addressing social determinants contributing to poor care engagement among people living with HIV (PLH), such as food insecurity. Food insecurity is associated with poor care engagement among PLH. Yet, few studies have examined the perspectives of healthcare and social services providers on addressing food insecurity in HIV care. Guided by the Social Ecological Model, we conducted semi-structured interviews with 18 providers in New York State to understand barriers and facilitators to addressing food insecurity in HIV care. Thematic analysis illustrated eight themes across various levels of the Social Ecological Model. At the patient-level, providers perceived patients' feelings of embarrassment, shame, and judgement, and low health literacy as barriers. At the provider-level, challenges included limited time. Facilitators included fostering strong, patient-provider relationships. Barriers at the clinic-level included limited funding, while clinic resources served as facilitators. At the community-level, challenges included intersecting stigmas arising from community norms towards PLH and people who receive food assistance and limited access to healthy food. Findings suggest the need to incorporate their insights into the development of interventions that address food insecurity in HIV care.

RESUMO

Introduction: Attaining The Joint United Nations Programme on HIV/AIDS 95-95-95 targets to end the HIV epidemic by 2030 will require a greater understanding of the underlying mechanisms influencing care engagement among people living with HIV/AIDS (PLWHA). One such mechanism is food insecurity, defined as limited or uncertain access to food. Food insecurity has been shown to significantly impact HIV outcomes. Yet, few studies have examined the mechanisms through which food insecurity may influence these outcomes. We aimed to examine the effects of nutritional, behavioral, and mental health mechanisms through which food insecurity may impact HIV care continuum outcomes: receipt of care, retention in care, and viral suppression. Methods: We conducted a cross-sectional study of 200 PLWHA in New York State, United States from May-August 2022. Participants were recruited using convenience sampling methods. Multivariable logistic regression models were conducted to examine the associations between food insecurity and care continuum outcomes (receipt of care, retention in care, viral suppression), adjusting for age, race, ethnicity, education, income, and marital status. Individual causal mediation analyses were conducted to assess whether behavioral, mental health, and nutritional mechanisms mediated the hypothesized associations. Results: The median age of participants was 30 years (IQR: 27-37 years). The majority self-identified as Black (54.0%), male (55.5%) and straight/heterosexual (63.0%). Increasing severity of food insecurity was associated with greater odds of non-retention in care (aOR: 1.35, 95% CI: 1.07, 1.70) and viral non-suppression (aOR: 1.29, 95% CI: 1.08, 1.54). For the impact of food insecurity on non-retention in care, there was an indirect relationship (natural indirect effect; NIE) mediated through Body Mass Index (BMI) (ORNIE: 1.08, 95% CI: 1.00, 1.18). For viral non-suppression, there was an indirect relationship mediated through BMI (ORNIE: 1.07, 95% CI: 1.00,1.16) and an indirect relationship mediated through depression (ORNIE: 1.27, 95% CI: 1.07, 1.47). Discussion: Food insecurity was associated with greater odds of non-retention in care and viral non-suppression among PLWHA. Nutritional and mental health pathways are important mediators of these relationships. Results highlight the need for interventions to target these pathways to address food insecurity as an underlying mechanism influencing engagement in HIV care.

RESUMO

BACKGROUND: Creating strong partnerships with community organizations is essential to test implementation of evidence-based interventions. However, partners are often chosen based on convenience rather than capacity or diversity. Streamlined processes are needed to identify qualified, diverse, and invested partners to conduct community-based research. OBJECTIVES: There is a gap in the literature on effective and efficient processes for recruiting partners. This paper aims to fill that gap by describing a novel approach for identifying a diverse group of community organizations to participate in research. METHODS: We used a Request for Partners (RFP) approach to recruit partners to participate in a hybrid implementation-effectiveness study of the Veggie Van mobile market model. The process included formative work to inform RFP development, creation of an external advisory committee, an intent-to-apply round, a full application round, and an inperson training and selection process. Data was collected to characterize applicant size, location, and experience; pre-post surveys were conducted to understand the training's utility. RESULTS: We received 59 intent-to-apply submissions and invited 28 organizations to apply: 17 submitted applications and 12 organizations were chosen as finalists. The process took approximately 8 months to recruit 9 organizations and 32 community sites across 5 states and increased understanding of the intervention and partner responsibilities. CONCLUSIONS: An RFP process is familiar to many community organizations that compete for grant funding but may not have prior research experience. This process streamlined recruitment timelines, increased diversity, and cultivated community among organizations. It may also improve research transparency, study completion, and intervention fidelity.

RESUMO

OBJECTIVE: To examine the feasibility and implementation of an optimal defaults intervention designed to align grocery purchases with a diet recommended for people with or at-risk for type 2 diabetes. DESIGN: This was a 5-week pilot randomised trial with three groups: in-person grocery shopping, shopping online and shopping online with 'default' carts. Participants were asked to shop normally in Week One, according to group assignment in Weeks Two-Four (intervention period), and as preferred in Week Five. All groups received diabetes-friendly recipes via email each intervention week. SETTING: Participants grocery shopped in person or online. Grocery receipt forms, enrolment information and exit surveys were collected remotely and used to assess feasibility and implementation. PARTICIPANTS: Sixty-five adults with or at-risk for type 2 diabetes. RESULTS: Sixty-two participants completed the exit survey and fifty-five submitted receipts all 5 weeks. Forty utilised recipes, 95 % of whom indicated recipes were somewhat or very useful. Orange chicken, quesadillas and pork with potato and apples were the most liked recipes. Most Defaults group participants accepted at least some default cart items. Recipes with the highest default acceptance were whole grain pasta and chicken, quesadillas with black beans and chicken with olives. Participants' primary concerns about the intervention were costs associated with online shopping, inability to select preferred foods and some recipes including ingredients household members would not eat. CONCLUSIONS: The study had high retention, data were successfully collected remotely and the intervention was acceptable to most participants. Tailoring recipes to household preferences may be beneficial in future studies.

RESUMO

INTRODUCTION: Randomized controlled trials (RCTs) suggested that liquid formulation of botulinum toxin type A (aboBoNT-A) is safe and effective, but data confirming these characteristics in a real-life heterogenous set of patients are currently lacking. This study aimed to assess the efficacy and safety of the ready-to-use aboBoNT-A solution in adults with moderate-to-severe glabellar wrinkles. METHODS: In this real-life, multicenter, retrospective, observational study, healthy adults were treated at baseline only with aboBoNT-A solution on the glabellar area and followed up for 24 weeks. Re-treatment after 20-24 weeks could also be combined with other aesthetic procedures. Family history of immune-mediated inflammatory diseases (IMIDs) was not an exclusion criterion. Patient-reported outcomes (patient's satisfaction and injection-related pain) and physician-reported outcomes (Physician Global Assessment, PGA) were collected. RESULTS: Of the 542 patients enrolled in the study, 38 had IMID family history. Injection-related pain was reported in 128 (23.62%) as mild (pain VAS = 1.34 ± 0.87) mainly by non-botulinum toxin treatment-naïve women under 50 years of age. At 48 h, physicians rated the clinical result as "improved" in 64% of patients, conversely 264 patients (48.71%) self-evaluated as "satisfied"/"very satisfied". At 4 weeks a touch-up (< 10 units) was performed in 11 (2.03%) patients and 98.2% were "highly satisfied". Re-treatment was performed in 330 (61.45%) patients, mainly botulinum-experienced, at 20 weeks and in 207 (38.55%), mainly botulinum naïve, at 24 weeks. A total of 403 (74.35%) patients were re-treated with the three-point technique and 201 (37.08%) also received hyaluronic acid filler in the lower central face and middle third. There were no cases of de novo IMIDs. CONCLUSIONS: Real-world data confirmed that aboBoNT-A is a fast, efficient, durable, reproducible, and easy-to-use drug which is also well tolerated in patients with family history of IMID.

RESUMO

OBJECTIVE: The decision to eat is often a choice made in the context of food and non-food alternatives. However, no research, to the authors' knowledge, has assessed the combination of the motivation to eat, as indexed by the relative reinforcing value of food (RRVFOOD ), and the enriched home environment, i.e., access to activities that can serve as alternatives to eating on weight gain. METHODS: This study used a cross-sectional design to study how RRVFOOD and the enriched home environment predict percent overweight change over 2 years in 291 children aged 6 to 9 years and of varying socioeconomic status. RESULTS: Results showed that RRVFOOD and access to food were positively associated with baseline percent overweight, and an enriched home environment was negatively related to baseline percent overweight. RRVFOOD and an enriched home environment interacted to predict change in percent overweight. Children with a high relative RRVFOOD and a relatively non-enriched environment showed the greatest relative weight gain. CONCLUSIONS: These results suggest that providing an enriched home environment may reduce the effects of food reinforcement and being motivated to eat on weight gain in childhood, and this represents a novel approach to intervention that can be used to strengthen current behavioral approaches to prevent obesity in children.

RESUMO

OBJECTIVE: The goal of this study was to examine the potential of an optimal-defaults intervention to promote grocery purchases corresponding to a diet for diabetes. METHODS: In total, 65 adults diagnosed with or at increased risk for type 2 diabetes who grocery shopped at one of two study stores were randomized to one of three groups: Defaults, Online, or Control. All groups received diabetes-friendly recipes. In addition, the Online group was asked to grocery shop online during a 3-week intervention, and the Defaults group was asked to shop online, with their online grocery carts prefilled with food items needed to prepare provided recipes. Participants provided weekly grocery receipt data at baseline, at each week of the 3-week intervention, and at post-intervention. RESULTS: Overall, the Defaults group had grocery purchases of a significantly greater nutritional quality versus other groups (F = 16.3, p < 0.001). Between-group comparisons of least-squares means showed consistent effects of the Defaults intervention while intervention components were in place, with a similar pattern for energy and carbohydrate content of grocery purchases. CONCLUSIONS: These results build upon emerging evidence that optimal defaults can promote healthier grocery purchases. Continued examination of this approach could promote healthy food acquisition in accordance with individual dietary preferences and needs.

RESUMO

Achieving HIV prevention goals will require successful engagement in each stage of the HIV continuum. The present study sought to understand the ways in which socio-structural factors influence HIV care engagement among people living with HIV (PLH) within the context of the ongoing COVID-19 pandemic. Twenty-five PLH were recruited from January to October 2021. Semi-structured interviews discussed various socio-contextual factors that influenced engagement in HIV-related care as a result of the pandemic. A thematic content analysis reported semantic level themes describing factors influencing HIV care following an integrated inductive-deductive approach. Qualitative analysis revealed three themes that either supported or hindered engagement in care within the context of the COVID-19 pandemic: (1) social determinants of health, (2) social support, and (3) modes of healthcare delivery. The results underscore the need to assess socio-structural factors of health as means to promote successful engagement in the HIV care continuum and shed new insights to guide future practice in the era of COVID-19.

RESUMO

Early-life metabolic stress has been demonstrated to affect brain development, persistently influence brain plasticity and to exert multigenerational effects on cognitive functions. However, the impact of an ancestor's diet on the adult neurogenesis of their descendants has not yet been investigated. Here, we studied the effects of maternal high fat diet (HFD) on hippocampal adult neurogenesis and the proliferation of neural stem and progenitor cells (NSPCs) derived from the hippocampus of both the second and the third generations of progeny (F2HFD and F3HFD). Maternal HFD caused a multigenerational depletion of neurogenic niche in F2HFD and F3HFD mice. Moreover, NSPCs derived from HFD descendants showed altered expression of genes regulating stem cell proliferation and neurodifferentiation (i.e., Hes1, NeuroD1, Bdnf). Finally, ancestor HFD-related hyper-activation of both STAT3 and STAT5 induced enhancement of their binding on the regulatory sequences of Gfap gene and an epigenetic switch from permissive to repressive chromatin on the promoter of the NeuroD1 gene. Collectively, our data indicate that maternal HFD multigenerationally affects hippocampal adult neurogenesis via an epigenetic derangement of pro-neurogenic gene expression in NSPCs.

RESUMO

BACKGROUND: Mobile produce markets were increasingly recognized as an effective and accepted approach to improving access to fruits and vegetables in lower-income and at-risk communities during the first year of the COVID-19 pandemic in the United States. This study provides insights into how mobile market operations were impacted by, and evolved in response to, challenges posed by the pandemic. METHODS: A survey evaluating impacts of the pandemic on mobile markets was distributed to a database of mobile market operators in the United States. Respondents were asked to describe impacts to their mobile market's operations, and what adaptations were needed to continue to effectively serve their communities during 2020. RESULTS: Surveys representing 48 unique mobile markets were collected from March to July 2021. Of the respondents, 63% reported an increase in demand for mobile market services from community members. Furthermore, 65% increased the amount of produce they distributed in 2020 as compared to 2019, often through adopting low or no-cost models or participating in pandemic government programs. DISCUSSION: Emergency adaptations employed by mobile markets can inform long-term operational modifications for not only mobile markets, but also other food access programs, beyond the COVID-19 pandemic.

RESUMO

Mobile produce markets are increasingly popular retail vendors used for providing access to fresh fruits and vegetables (F&V) in under-resourced communities; however, evaluation is limited due to design and implementation challenges. This protocol presents the original design of a randomized control trial aimed at assessing the effectiveness of the evidence-based Veggie Van (VV) mobile market model. Nine US community partner organizations were asked to partner with four community sites serving lower-income areas. Sites are randomized to either intervention or control. Intervention sites will host a mobile market for one year while the control sites will host planning events, with the goal to open a market afterward. Eligible participants are aged ≥ 18, the primary household shopper, live nearby/regularly frequent the site, and have expressed interest in learning about a mobile market. The primary outcome, F&V consumption, will be assessed via dietary recall at baseline and 12 months and compared between the intervention and control sites. This research advances work on the VV model and methods for mobile market evaluation with the addition of more robust measures and the study design. Determining the effectiveness of the VV model is imperative to justify taking it to scale to enhance the impact of mobile markets.

RESUMO

Mission-driven, independently-owned community food stores have been identified as a potential solution to improve access to healthy foods, yet to date there is limited information on what factors contribute to these stores' success and failure. Using a multiple case study approach, this study examined what makes a healthy community food store successful and identified strategies for success in seven community stores in urban areas across the United States. We used Stake's multiple case study analysis approach to identify the following key aims that contributed to community store success across all cases: (1) making healthy food available, (2) offering healthy foods at affordable prices, and (3) reaching community members with limited economic resources. However, stores differed in terms of their intention, action, and achievement of these aims. Key strategies identified that enabled success included: (1) having a store champion, (2) using nontraditional business strategies, (3) obtaining innovative external funding, (4) using a dynamic sourcing model, (5) implementing healthy food marketing, and (6) engaging the community. Stores did not need to implement all strategies to be successful, however certain strategies, such as having a store champion, emerged as critical for all stores. Retailers, researchers, philanthropy, and policymakers can utilize this definition of success and the identified strategies to improve healthy food access in their communities.

RESUMO

Community engagement is well established as a key to improving public health. Prior food environment research has largely studied community engagement as an intervention component, leaving much unknown about how food retailers may already engage in this work. The purpose of this study was to explore the community engagement activities employed by neighborhood food retailers located in lower-income communities with explicit health missions to understand the ways stores involve and work with their communities. A multiple case study methodology was utilized among seven retailers in urban U.S. settings, which collected multiple sources of data at each retailer, including in-depth interviews, store manager sales reports, store observations using the Nutrition Environment Measures Survey for Stores, public documents, and websites. Across-case analysis was performed following Stake's multiple case study approach. Results indicated that retailers employed a wide variety of forms of community engagement within their communities, including Outreach, Building Relationships through Customer Relations, Giving Back, Partnering with Community Coalitions, and Promoting Community Representation and Inclusiveness. Strategies that built relationships through customer relations were most common across stores; whereas few stores demonstrated community inclusiveness where members participated in store decision making. Findings provide a more comprehensive view of the ways local food retailers aim to develop and sustain authentic community relationships. Additional research is needed to evaluate the impact of community engagement activities on improving community health.

RESUMO

INTRODUCTION: Mobile produce markets are becoming an increasingly prevalent, accepted, and effective strategy for improving fruit and vegetable (F&V) access and consumption across underserved and lower-income communities. However, there is limited published research on mobile market operations. The goal of this research is to identify the challenges mobile markets face and ways to potentially mitigate those challenges. We will also discuss implications of our findings for future implementation of evidence-based food access interventions. METHODS: We conducted 21 semi-structured key informant (KI) interviews to assess common practices of mobile market organizations that had been operating for 2 + years. We asked KIs about their organizational structure, operations, procurement and logistics, evaluation efforts, marketing and community engagement, success and challenges. A primary qualitative analysis involved deductive coding using qualitative software. A secondary qualitative analysis identified subthemes related to common challenges and remedial practices. A deductive coding process was applied to match identified challenges to the appropriate Consolidated Framework for Implementation Research (CFIR). RESULTS: The leading challenges cited by KIs correspond to the CFIR domains of inner setting (e.g., funding and resources), outer setting (e.g., navigating regulations), and process (e.g., engaging community partnership). Practices that may mitigate challenges include maximizing ancillary services, adopting innovative volunteer and staffing structures, and formalizing agreements with community partners. CONCLUSION: Common and persistent challenges ought to be addressed to ensure and enhance the positive public health impacts of mobile produce markets. Contextual factors, particularly organizational factors, that impact implementation should also be considered when implementing an evidence-based intervention at a mobile market. Further research is needed to determine which innovative solutions are the most effective in mitigating challenges, improving implementation, and enhancing sustainability of mobile markets.

RESUMO

Neural stem and progenitor cell (NSPC) depletion may play a crucial role in the cognitive impairment observed in many age-related non-communicable diseases. Insulin resistance affects brain functions through a plethora of mechanisms that remain poorly understood. In an experimental model of insulin resistant NSPCs, we identified a novel molecular circuit relying on insulin receptor substrate-1 (IRS-1)/ Forkhead box O (FoxO) signaling cascade and inhibiting the recruitment of transcription factors FoxO1 and FoxO3a on the promoters of genes regulating proliferation and self-renewal. Insulin resistance also epigenetically increased the expression of cyclin-dependent kinase inhibitor 1 (p21) and accelerated NSPC senescence. Of note, we found that stimulation of NSPCs with NSPC-derived exosomes (exo-NSPC) rescued IRS-1/FoxO activation and counteracted both the reduced proliferation and senescence of stem cells. Accordingly, intranasal administration of exo-NSPC counteracted the high-fat diet-dependent impairment of adult hippocampal neurogenesis in mice by restoring the balance between proliferating and senescent NSPCs in the hippocampus. Our findings suggest a novel mechanism underlying the metabolic control of NSPC fate potentially involved in the detrimental effects of metabolic disorders on brain plasticity. In addition, our data highlight the role of extracellular vesicle-mediated signals in the regulation of cell fate within the adult neurogenic niche.

RESUMO

Improving healthy food access in low-income communities continues to be a public health challenge. One strategy for improving healthy food access has been to introduce community food stores, with the mission of increasing healthy food access; however, no study has explored the experiences of different initiatives and models in opening and sustaining healthy food stores. This study used a case study approach to understand the experiences of healthy food stores in low-income communities. The purpose of this paper is to describe the methodology used and protocol followed. A case study approach was used to describe seven healthy food stores across urban settings in the U.S. Each site individually coded their cases, and meetings were held to discuss emerging and cross-cutting themes. A cross-case analysis approach was used to produce a series of papers detailing the results of each theme. Most case studies were on for-profit, full-service grocery stores, with store sizes ranging from 900 to 65,000 square feet. Healthy Food Availability scores across sites ranged from 11.6 (low) to 26.5 (high). The papers resulting from this study will detail the key findings of the case studies and will focus on the challenges, strategies, and experiences of retail food stores attempting to improve healthy food access for disadvantaged communities. The work presented in this special issue will help to advance research in the area of community food stores, and the recommendations can be used by aspiring, new, and current community food store owners.

RESUMO

Alcohol mixed energy drinks (AmED) may promote excessive alcohol intake and risk-taking among college students. Objective: To understand the relationship between AmED use and risky behavior as well as attitudes and motivations for AmED use. Participants: Undergraduate college students N = 422 (Study 1), N = 37 (Study 2). Methods: Using a mixed-methods approach, we first surveyed undergraduate students about their AmED and alcohol consumption and a series of risk behaviors, self-efficacy, and beliefs (Study 1). We then conducted focus groups within the same population to better understand attitudes, knowledge, and motivations for using AmED (Study 2). Results: Recent AmED use was significantly associated with an increased number of reported binge drinking occasions and self-reported driving while intoxicated events. Our qualitative data analyses revealed two major themes associated with AmED consumption: factors encouraging AmED use and decisions about driving while under the influence of alcohol. Conclusions: These findings add to the literature of beliefs and motivations for AmED use among college students.
