RESUMO
Primary care physicians (PCPs) are well suited to manage patients with non-alcoholic fatty liver disease (NAFLD), but the limited, existing research suggests inadequate knowledge about the natural history, diagnostic methods, and management of NAFLD. The purpose of this qualitative study is to further understand the knowledge and practices for the diagnosis and management of NAFLD among PCPs. We conducted in-depth interviews with PCPs in the Greater Houston area, addressing current clinical practices used for diagnosing and managing NAFLD, as well as the perceptions of the PCPs regarding the burden of NAFLD on patients. We recorded interviews, transcribed them, coded transcripts, and identified patterns and themes. The interviewed PCPs (n = 16) were from internal or family medicine, with a range of experience (1.5-30 years). We found variations in NAFLD diagnosis and management across practices and by insurance status. Patients with abnormal liver imaging who had insurance or were within a safety-net healthcare system were referred by PCPs to specialists. Uninsured patients with persistently elevated liver enzymes received lifestyle recommendations from PCPs without confirmatory imaging or specialist referral. The role of PCPs in NAFLD management varied, with some helping patients set dietary and physical activity goals while others provided only general recommendations and/or referred patients to a dietitian. The diagnosis and management of NAFLD vary widely among PCPs and may be impacted by patients' insurance status and clinic-specific practices. The increasing burden of NAFLD in the U.S. medical system highlights the need for more PCPs involvement in managing NAFLD.

Community involvement in research is key to translating science into practice, and new approaches to engaging community members in research design and implementation are needed. The Community Scientist Program, established at the MD Anderson Cancer Center in Houston in 2018 and expanded to two other Texas institutions in 2021, provides researchers with rapid feedback from community members on study feasibility and design, cultural appropriateness, participant recruitment, and research implementation. This paper aims to describe the Community Scientist Program and assess Community Scientists' and researchers' satisfaction with the program. We present the analysis of the data collected from 116 Community Scientists and 64 researchers who attended 100 feedback sessions, across three regions of Texas including Northeast Texas, Houston, and Rio Grande Valley between June 2018 and December 2022. Community Scientists stated that the feedback sessions increased their knowledge and changed their perception of research. All researchers (100%) were satisfied with the feedback and reported that it influenced their current and future research methods. Our evaluation demonstrates that the key features of the Community Scientist Program such as follow-up evaluations, effective bi-directional communication, and fair compensation transform how research is conducted and contribute to reducing health disparities.
RESUMO
INTRODUCTION: The COVID-19 pandemic has prompted governments internationally to consider strengthening their public health systems. To support the work of Ireland's Public Health Reform Expert Advisory Group, the Health Information and Quality Authority, an independent governmental agency, was asked to describe the lessons learnt regarding the public health response to COVID-19 internationally and the applicability of this response for future pandemic preparedness. METHODS: Semi-structured interviews with key public health representatives from nine countries were conducted. Interviews were conducted in March and April 2022 remotely via Zoom and were recorded. Notes were taken by two researchers, and a thematic analysis undertaken. RESULTS: Lessons learnt from the COVID-19 pandemic related to three main themes: 1) setting policy; 2) delivering public health interventions; and 3) providing effective communication. Real-time surveillance, evidence synthesis, and cross-sectoral collaboration were reported as essential for policy setting; it was noted that having these functions established prior to the pandemic would lead to a more efficient implementation in a health emergency. Delivering public health interventions such as testing, contact tracing, and vaccination were key to limiting and or mitigating the spread of the SARS-CoV-2 virus. However, a number of challenges were highlighted such as staff capacity and burnout, delays in vaccination procurement, and reduced delivery of regular healthcare services. Clear, consistent, and regular communication of the scientific evidence was key to engaging citizens with mitigation strategies. However, these communication strategies had to compete with an infodemic of information being circulated, particularly through social media. CONCLUSIONS: Overall, functions relating to policy setting, public health interventions, and communication are key to pandemic response. Ideally, these should be established in the preparedness phase so that they can be rapidly scaled-up during a pandemic.

Breast cancer is the most common cancer in women globally with enormous associated morbidity, mortality and economic impact. Prevention of breast cancer is a global public health imperative. To date, most of our global efforts have been directed at expanding population breast cancer screening programs for early cancer detection and not at breast cancer prevention efforts. It is imperative that we change the paradigm. As with other diseases, prevention of breast cancer starts with identification of individuals at high risk, and for breast cancer this requires improved identification of individuals who carry a hereditary cancer mutation associated with an elevated risk of breast cancer, and identification of others who are at high risk due to non-genetic, established modifiable and non-modifiable factors. This article will review basic breast cancer genetics and the most common hereditary breast cancer mutations associated with increased risk. We will also discuss the other non-genetic modifiable and non-modifiable breast cancer risk factors, available risk assessment models and an approach to incorporating screening for genetic mutation carriers and identifying high-risk women in clinical practice. A discussion of guidelines for enhanced screening, chemoprevention and surgical management of high-risk women is beyond the scope of this review.

The first successful solid organ transplant was a living donor kidney transplant in 1954. Since then, living donation has been an important source of organs for kidney and liver transplants in the United States. Unfortunately, the demand for organs has not kept pace with the supply, and unlike deceased donor transplant, there has been little growth in the number of living donor transplants over the past decade. To better understand possible barriers to living donation and long-term risks attributable to donation, the Health Resources and Services Administration (HRSA) directed the Scientific Registry of Transplant Recipients (SRTR) to establish a national registry of all living donor candidates and donors evaluated at US transplant programs to acquire lifetime follow-up information. Other goals include understanding the factors associated with candidate approval and variation in approval practices across centers. A pilot program was conducted from June 2018 through September 2020 to inform baseline data collection and registration processes. In September 2020, the registry began recruiting additional sites evaluating candidates for living donation. Here, we describe candidates registered at participating living donor kidney and liver programs, from June 2018 through the end of 2020. Not all programs submitted data throughout the whole period. Data for kidney and liver living donor candidates are presented separately.

The year 2020 presented significant challenges to the field of kidney transplantation. After increasing each year since 2015 and reaching the highest annual count to date in 2019, the total number of kidney trans- plants decreased slightly, to 23642, in 2020. The decrease in total kidney transplants was due to a decrease in living donor transplants; the number of deceased donor transplants rose in 2020. The number of patients waiting for a kidney transplant in the United States declined slightly in 2020, driven by a slight drop in the number of new candidates added in 2020 and an increase in patients removed from the waiting list owing to death-important patterns that correlated with the COVID-19 pandemic. The complexities of the pandemic were accompanied by other ongoing challenges. Nationwide, only about a quarter of waitlisted patients receive a deceased donor kidney transplant within 5 years, a proportion that varies dramatically by donation service area, from 14.8% to 73.0%. The nonutilization (discard) rate of recovered organs rose to its highest value, at 21.3%, despite a dramatic decline in the discard of organs from hepatitis C-positive donors. Nonutilization rates remain particularly high for Kidney Donor Profile Index ≥85% kidneys and kidneys from which a biopsy specimen was obtained. Due to pandemic-related disruption of living donation in spring 2020, the number of living donor transplants in 2020 declined below annual counts over the last decade. In this context, only a small proportion of the waiting list receives living donor transplants each year, and racial disparities in living donor transplant access persist. As both graft and patient survival continue to improve incrementally, the total number of living kidney transplant recipients with a functioning graft exceeded 250,000 in 2020. Pediatric transplant numbers seem to have been impacted by the COVID-19 pandemic. The total number of pediatric kidney transplants performed decreased to 715 in 2020, from a peak of 872 in 2009. Despite numerous efforts, living donor kidney transplant remains low among pediatric recipients, with continued racial disparities among recipients. Of concern, the rate of deceased donor transplant among pediatric waitlisted candidates continued to decrease, reaching its lowest point in 2020. While this may be partly explained by the COVID-19 pandemic, close attention to this trend is critically important. Congenital anomalies of the kidney and urinary tract remain the leading cause of kidney disease in the pediatric population. While most pediatric de- ceased donor recipients receive a kidney from a donor with KDPI less than 35%, most pediatric deceased donor recipients had four or more HLA mis- matches. Graft survival continues to improve, with superior survival for living donor recipients versus deceased donor recipients.

BACKGROUND: Limited information exists on how the family unit aids or impedes physical activity (PA) engagement within Hispanic populations. This qualitative study explored family-level influences on PA in dyads of adult Hispanic family members (eg, parent-adult child, siblings, spouses). METHODS: In-person interviews and brief surveys were conducted together with 20 dyads lasting 1.5 hours each. Two researchers coded and analyzed text using thematic analysis in NVivo (version 11.0). They resolved discrepancies through consensus and used matrix coding analysis to examine themes by participants' demographics. RESULTS: The participants were mainly women (70%), from Mexico (61.5%), and they reported low levels of acculturation (87.5%). Themed facilitators for PA included "verbal encouragement," "help with responsibilities," "exercising with someone," and "exercising to appease children." Themed challenges included "lack of support," "challenges posed by children," "sedentary behaviors," and "competing responsibilities." Women more so than men described family-level challenges and facilitators, and dyads where both study partners were physically active provided more positive partner interaction descriptions for PA support than other dyads. CONCLUSIONS: This study suggests that leveraging family support may be an important approach to promote and sustain PA, and that family-focused interventions should integrate communication-building strategies to facilitate family members' ability to solicit support from each other.

OBJECTIVE: To refine a measure of home cooking quality (defined as the usage level of practices with the potential to influence the nutrient content of prepared foods) and conduct a construct validation of the revised tool, the Healthy Cooking Questionnaire 2 (HCQ2). DESIGN: Two validation approaches are described: (1) a community science approach used to refine and validate Healthy Cooking Questionnaire (HCQ) constructs, and (2) responses to the revised HCQ (HCQ2) in a sample of Amazon Mechanical Turk (MTurk) workers to determine questionnaire comprehension. SETTING: The Community Scientist Program at the University of Texas MD Anderson Cancer Center facilitated discussion groups to refine the HCQ questions and validate constructs. MTurk workers were subsequently recruited to complete the refined survey so that comprehension and associations with demographic variables could be explored. PARTICIPANTS: Ten community scientists participated in the refinement of the HCQ. The revised tool (HCQ2) was completed by 267 adult US-based MTurk workers. VARIABLES MEASURED: Demographics, HCQ concepts, HCQ2, Self-Reported Questionnaire Comprehension. ANALYSIS: Comprehension items were examined using descriptive statistics. Exploratory analysis the relationships between cooking quality and demographic characteristics, meal type, cooking frequency, as well as patterns of food preparation behavior was conducted on the MTurk sample RESULTS: The HCQ was refined through activities and consensus-building. MTurk responses to the HCQ2 indicated high comprehension and significant differences in cooking quality scores by demographic factors. CONCLUSIONS AND IMPLICATIONS: This study refined and validated a self-report measure of cooking quality. Cooking quality measures offer critical evaluation methods for culinary programs.

BACKGROUND: Conflicting breast cancer screening recommendations have the potential to diminish informed decision making about screening. OBJECTIVE: We examined the knowledge, attitudes, and intentions related to divergent recommendations for breast cancer screening among racially/ethnically diverse women. DESIGN: We used a multimethod study design employing focus groups and questionnaires. Focus groups included: (1) two 10-min presentations on the national screening recommendations and the potential benefits and harms of screening and (2) an interactive discussion. Data were collected: 8/3/2017 to 11/19/2019. Analysis occurred from 1/21/2019 to 7/24/2020. PARTICIPANTS: Participants were (1) women 40-75 years; (2) English or Spanish speaking; (3)self-identified as Latina, Black, or non-Latina White; and (4) no known increased risk for breast cancer. MAIN MEASURES: Main outcomes were participants' knowledge and perceptions of benefits and harms of screening mammography and their screening intentions. Focus groups were transcribed and analyzed using a qualitative descriptive approach. Quantitative data were summarized using descriptive statistics. KEY RESULTS: One hundred thirty-four women (n=52, 40-49 years; n=82, 50-75 years) participated in 28 focus groups. Participants were Latina (n=44); Black (n=51); and non-Latina White (n=39). Approximately one-quarter (n=32) had limited health literacy and almost one-fifth (n=23) had limited numeracy. In the context of differing national screening recommendations, participants questioned the motives of the recommendation-making agencies, including the role of costs and how costs were considered when making screening recommendations. Participants expressed concern that they were not represented (e.g., race/ethnicity) in the data informing the recommendations. Immediately following the focus groups, most participants expressed intention to screen within the upcoming year (pre n=100 vs. post n=107). CONCLUSIONS: Divergent breast cancer screening recommendations may lead to mistrust and paradoxically reinforce high overall enthusiasm for screening.

BACKGROUND: Individuals at increased hereditary risk of cancer are an important target for health promotion and cancer prevention interventions. Health-4-Families uses the Multiphase Optimization STrategy (MOST) framework and is designed to pilot digital delivery strategies for a distance-based, 16-week intervention to promote weight management, healthy diet, and increased physical activity among individuals with BRCA1/BRCA2 or DNA mismatch repair (MMR) pathogenic germline variants. This communication describes participant recruitment and the design of the Health-4-Families pilot study. METHODS: Health-4-Families is a full-factorial (16 condition) randomized pilot study of four lifestyle intervention components: social networking, telephone or email coaching, text messaging, and self-monitoring. The primary outcome was feasibility and satisfaction with these study components. Participants with pathogenic germline variants were identified via clinic surveillance lists and advocacy organizations and were invited to participate with family members. All participants had to report meeting at least one of the following criteria: (1) having a BMI ≥ 25 kg/m2, (2) consuming <5 servings of fruit and vegetables per day, or (3) getting <150 min of moderate-to-vigorous intensity activity per week. RESULTS: The majority of screened potential participants with pathogenic variants (83%) were eligible; 86% of those eligible provided informed consent and 79% (n = 104) completed baseline. A total of 206 family members were nominated by study participants and 49% (n = 102) completed baseline. DISCUSSION: Recruitment data suggest that individuals with pathogenic germline variants, who are at increased risk for hereditary cancers, are motivated to participate in digital lifestyle interventions. This recruitment success highlights the importance of identifying and prioritizing effective and efficient intervention components for hereditary cancer families. We intend to use the outcomes of our pilot study to inform a fully-powered factorial study for this community.

INTRODUCTION: Women with pathogenic germline gene variants in BRCA1 and/or BRCA2 are at increased risk of developing ovarian and breast cancer. While surgical and pharmacological approaches are effective for risk-reduction, it is unknown whether lifestyle approaches such as healthful dietary habits, weight management, and physical activity may also contribute to risk-reduction. We conducted a systematic review of evidence related to dietary habits, weight status/change, and physical activity on ovarian and breast cancer risk among women with BRCA1/2 pathogenic variants. METHODS: We searched Medline, EMBASE, CENTRAL, PubMed, and clinicaltrials.gov up to October 3, 2019. We identified 2775 records and included 21. RESULTS: There is limited evidence related to these factors and ovarian cancer risk. For breast cancer risk, evidence suggests higher diet quality, adulthood weight-loss of ≥10 pounds, and activity during adolescence and young-adulthood may be linked with decreased risk. Higher meat intake and higher daily energy intake may be linked with increased risk. CONCLUSIONS: There is not enough evidence to suggest tailored recommendations for dietary habits or weight management among women with BRCA1/2 pathogenic variants compared to the general population for ovarian and breast cancer risk-reduction, and physical activity recommendations should remain the same.
RESUMO
Physical activity reduces cancer risk, yet African American adults remain insufficiently active, contributing to cancer health disparities. Harmony & Health (HH) was developed as a culturally adapted mind-body intervention to promote physical activity, psychosocial well-being, and quality of life among a church-based sample of overweight/obese, insufficiently active African American adults. Men and women were recruited to the study through an existing church partnership. Eligible participants (N = 50) were randomized to a movement-based mind-body intervention (n = 26) or waitlist control (n = 24). Participants in the intervention attended 16 mind-body sessions over 8 weeks and completed a physical assessment, questionnaires on moderate-to-vigorous physical activity (MVPA) and psychosocial factors, and accelerometry at baseline (T1), post-intervention (T2), and 6 week follow-up (T3). Eighty percent of participants (94% women, M age = 49.7 ± 9.4 years, M body mass index = 32.8 ± 5.2 kg/m2) completed the study, and 61.5% of intervention participants attended ≥10 mind-body sessions. Participants self-reported doing 78.8 ± 102.9 (median = 40.7, range: 0-470.7) min/day of MVPA and did 27.1 ± 20.7 (median = 22.0, range: 0-100.5) min/day of accelerometer-measured MVPA at baseline. Trends suggest that mind-body participants self-reported greater improvements in physical activity and psychosocial well-being from baseline to post-intervention than waitlist control participants. HH is feasible and acceptable among African American adults. Trends suggest that the mind-body intervention led to improvements in physical activity and psychosocial outcomes. This study extends the literature on the use of mind-body practices to promote physical and psychological health and reduce cancer disparities in African American adults.

Few efficacious interventions for tobacco use exist for Latinos. Identification of cultural factors relevant to smoking among Latinos can inform the development of efficacious interventions for Latino smokers. Acculturation is associated with smoking, especially among Latinas, but extant research is limited by operationalization of acculturation with unidirectional, single-domain proxies. We examined associations of multiple domains of acculturation with gender and smoking status among Latino adults. Cross-sectional data from 140 bilingual Latino adults was utilized. Acculturation was measured with the 4 subscales of the Multidimensional Acculturation Scale II (MAS-II). Logistic regression analyses tested interaction effects between MAS-II American and Latino Cultural Identification subscales, English and Spanish Proficiency subscales, and their interactions with gender, on smoking status. Higher English Proficiency was associated with greater odds of being a smoker at Spanish Proficiency scores of 4.5 or higher. Higher Latino Cultural Identification was associated with lower odds of being a smoker among women, but not men. Acculturation toward American culture, per se, may not be a risk factor for smoking; rather, its influence depends on Latino culture maintenance. Unlike in other areas of mental/behavioral health among Latinos, biculturalism may not be protective against smoking. The association between acculturation and smoking among Latinas may be a function of loss of Latino culture identification. Intervention programs should consider targeting these at-risk individuals. Longitudinal work that corroborates current findings and identifies mechanisms underlying these associations is needed.
RESUMO
BACKGROUND: Low health literacy (HL) is associated with poor health status and outcomes. Racial/ethnic minorities in the United States disproportionately experience low HL and HL-related health disparities. Among Latinos, acculturation is associated with health outcomes, but little is known about the relationship between acculturation and HL. OBJECTIVE: We examined associations of sociodemographic and acculturation variables with English- and Spanish-language HL among 142 bilingual Latino adults with adequate HL. METHODS: HL was assessed in English using the Rapid Estimate of Adult Literacy in Medicine (REALM) and in Spanish with the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA). Acculturation was assessed using the four subscales of the Multidimensional Acculturation Scale-II. Associations of sociodemographic data and acculturation with HL were examined using linear regression. KEY RESULTS: Higher education, higher income, higher English proficiency, and lower Latino cultural identification predicted REALM scores (ps <.05) in univariate models. When these variables were entered into a single model, only education and Latino cultural identification were associated with REALM scores. In univariate analyses, the following characteristics were associated with SAHLSA scores: female gender, being partnered, higher education, higher income, being non-US born, lower English proficiency, and higher Spanish proficiency (ps < .05). Education, being non-US born, English proficiency, and Spanish proficiency were each significant in the multivariate model. CONCLUSIONS: Results revealed a significant association between acculturation and English- and Spanish-language HL among bilingual Latino adults with adequate HL, suggesting that HL should be assessed in the language in which individuals are most proficient. HL assessed in a nonprimary language may be confounded with language proficiency. [HLRP: Health Literacy Research and Practice. 2019;3(2):e81-e89.]. PLAIN LANGUAGE SUMMARY: The results of this investigation revealed a significant association between acculturation and English- and Spanish-language health literacy among bilingual Latino adults. This suggests that health literacy should be assessed in the language in which individuals are most proficient. Health literacy assessed in a nonprimary language may be influenced by language proficiency.
RESUMO
Lifestyle factors related to energy balance, such as excess body weight, poor diet, and physical inactivity, are associated with risk of sporadic endometrial cancer (EC) and colorectal cancer (CRC). There are limited data on energy balance-related lifestyle factors and EC or CRC risk among individuals with lynch syndrome, who are at extraordinarily higher risk of developing EC or CRC. We conducted a systematic review of evidence related to weight status, weight change, dietary habits, and physical activity on EC and CRC risk among individuals with lynch syndrome. Findings are reported narratively. We searched Medline, EMBASE, CENTRAL, PubMed, and clinicaltrials.gov up to June 14th, 2018. In total, 1060 studies were identified and 16 were included. Three studies were related to EC and 13 to CRC. Overall, evidence suggests that weight status/weight change may not be associated with EC risk and multivitamin and folic-acid supplementation may be associated with decreased EC risk. Early-adulthood overweight/obese weight-status and adulthood weight-gain may be associated with increased CRC risk, whereas multivitamin supplementation, tea and high fruit intake, and physical activity may be associated with decreased CRC risk. Current evidence proposes that recommendations related to weight, some dietary habits, and physical activity recommended for the general public are also relevant to individuals with lynch syndrome. More research is needed, specifically prospective cohorts and randomized controlled trials, to determine if tailored recommendations are needed among individuals with lynch syndrome.

Objectives: In this study, we examined how racial discrimination and neighborhood perceptions relate to physical activity and sedentary behavior mediated through depression symptoms. Methods: Data were from the first year of a longitudinal cohort study, Project Creating a Higher Understanding of cancer Research and Community Health (CHURCH), based on a convenience community sample of church-attending African Americans collected between April 2012 and March 2013 (N = 370) in Houston, Texas. Measures included racial discrimination, perceived neighborhood problems and vigilance, depression (CES-D), physical activity (IPAQ-short), and sedentary behavior. Results: Main effects from the structural equation model showed that racial discrimination (b = .20, p < .01) was related to greater depression symptoms. The same pattern emerged for neighborhood problems, but the effect was not significant (b = .20, p = .07). Further, depression symptoms were related to less physical activity (b = -.62, p = .03) and greater sedentary behavior (b = .64, p < .01). Indirect effects showed that depression mediated the relationship between racial discrimination and neighborhood problems on physical activity and sedentary behavior. Conclusions: Depression symptoms are an important mechanism by which racial discrimination and perceived neighborhood problems impact physical activity and sedentary behavior.

Fresh betel leaves (Piper betle L.), imported into the UK are a traditional ready-to-eat food consumed by Asian populations. We report here the consolidation of routinely collected data to model the public health risks from consumption of this food. Amongst 2110 samples collected at Border Inspection, wholesale, catering or retail, Salmonella was detected in 488 (23%) of samples tested between 2011 and 2017 and was the most commonly Salmonella-contaminated ready-to-eat food examined by Public Health England during this period. Using data from multiple samples (usually 5) tested per consignment sampled at Border Inspection, contamination levels were calculated by most probable number: seasonal, temporal and country specific differences were detected. Quantitative contamination data was used to estimate the levels present at retail, and a ß-Poisson dose response model the probability of illness was calculated. Using data for products imported from India, the probability of acquiring infection following a single exposure (comprising of a single leaf) was estimated to be between 0.00003 (January-March) and 0.0001 (July-September). Using British Asian population data for individuals over 30â¯years of age in England in 2011, two estimates of consumption were modelled as 2.1 and 12.8 million servings per annum. Results from the model estimated 160 cases (range 102 to 242) and 960 cases (range 612 to 1456) per year in England for the two consumption estimates and equated to 34 (range 22 to 51) and 204 (range 130 to 310) salmonellosis cases per year reported to national surveillance. Salmonella from 475 of the contaminated samples were further characterised which showed a heterogeneous population structure with 46 S. enterica subsp. Enterica serovars, together with S. enterica subs diarizonae and salamae identified. Isolates from individual consignments were diverse and close genetic relationships between independent isolates were very rare except from within an individual consignment. There were no outbreaks detected as associated with betel leaf consumption. However analysis by whole genome sequencing of the 2014-17 data identified two cases where the clinical isolate had <5 single nucleotide polymorphism differences to isolates from betel leaves which is indicative of a likely epidemiological link and common source of contamination. Due to the diversity of the Salmonella contaminating this product, associations between salmonellosis cases and betel leaf consumption will appear sporadic and unlikely to be detected by current surveillance strategies based on outbreak detection.

We investigated class clustering patterns of four behaviors-physical activity, fruit and vegetable (F&V) intake, smoking, and alcohol use-in a faith-based African American cohort. Guided by socio-ecological models, we also examined the psychosocial and neighborhood social environmental factors associated with the clustering patterns. Participants were 1,467 African American adults recruited from a mega church in the metropolitan Houston, TX, in 2008-2009. They completed a survey and health assessment. Latent class analysis and multinomial regression analysis were conducted. Results supported a three-class model: Class 1 was characterized by low physical activity, low F&V intake, and low substance use (smoking and alcohol use). Class 2 was characterized by high physical activity, low F&V intake, and mild drinking. Class 3 seemed to be the healthiest group, characterized by high physical activity, moderate-to-high F&V intake, and low substance use. The probabilities of being included in Classes 1, 2, and 3 were .33, .48, and .19, respectively. Participants in Class 1 (vs. Class 3) reported lower physical activity norm ( p < .001) and higher smoking norm ( p = .002) and lower neighborhood social cohesion ( p = .031). Participants in Class 2 (vs. Class 3) reported higher cancer risk perception ( p < .001), lower F&V norm ( p = .022), lower physical activity norm ( p < .001), higher smoking norm ( p < .001), and lower social cohesion ( p = .047). As health behaviors are clustered together, future interventions for African Americans may consider targeting multiple health behaviors instead of targeting a single health behavior. Interventions addressing social norm and neighborhood social cohesion may enhance multiple health behaviors engagement in this population.
