Background: Limited evidence exists on the population attributable fraction (PAF) of cancer cases and deaths in Latin America. In Peru several studies have been published regarding the PAF of various risk factors and their associated diseases. The objective of this study was to estimate the fraction of cancer cases and deaths attributable to potentially modifiable risk factors in Peru in 2018, before the COVID-19 pandemic in the population of 15 years old and older., Methods: An ecological study was conducted using the prevalence of exposure of the Peruvian population to modifiable risk factors for cancer, the relative risk associated with each factor, and the number of cancer cases and deaths in 2018 as inputs. We used the Parkin formula with a Montecarlo statistical simulation model to calculate the PAF and confidence intervals. The number of new cancer cases and deaths attributed to each risk factor was determined by multiplying the number of cases and deaths in each gender by the PAF of each risk factor., Findings: In Peru, 38.5% of new cases (34.5% in men and 42% in women) and 43.4% of cancer-related deaths (43.4% in men and 43.4% in women) were attributable to modifiable risk factors. The number of cancers attributable was 25,308 (10,439 in men and 14,869 in women) and the number of deaths attributable to cancer was 14,839 (6,953 in men and 7,886 in women). The predominant modifiable risk factors contributing to the highest number of cases and deaths were HPV infection (4,563 cases, 2,409 deaths), current tobacco use (3,348 cases, 2,180 deaths), and helicobacter pylori infection (2,677 cases, 1,873 deaths). Among the risk factors, oncogenic infections constituted the group with the highest PAF (16.6% for cases, 19.2% for deaths) followed by other unhealthy lifestyle factors (14.2% for cases, 16.7% for deaths), tobacco (7.2% for cases, 7.2% for deaths) and ultraviolet radiation (0.5% for cases, 0.3% for deaths)., Conclusions: Prior to the COVID-19 pandemic, 38.5% of cancer cases and 43.4% of cancer-related deaths in Peru were linked to modifiable risk factors in the population of 15 years old and older. Most preventable cancer cases and deaths were related to oncogenic infections, primarily caused by HPV and helicobacter pylori, followed by tobacco and obesity., (© 2024. The Author(s).)

Background: Smoking among sexual and gender minority (SGM) groups, which include lesbian, gay, bisexual, transgender, and queer individuals, has been reported to be highly prevalent. This is attributed to several factors, including minority-specific stress and targeted tobacco marketing. Therefore, this population is at an increased risk for tobacco-related diseases. SMS text messaging programs have been found to be effective for smoking cessation and appeal to traditionally hard-to-reach populations over other interventions. It has also been suggested that targeted and tailored interventions could be more effective among SGM smokers because they can be designed to assure a safe, validating health care environment that enhances receptivity to cessation., Objective: The aim of this study is to develop SmokefreeSGM, a text-based smoking cessation program tailored to and tested among SGM smokers., Methods: The study consists of three phases, culminating in a feasibility trial. In Phase 1, our research team will collaborate with a Community Advisory Board to develop and pretest the design of SmokefreeSGM. In Phase 2, the tailored text messaging program will be beta tested among 16 SGM smokers. Our research team will use a mixed-methods approach to collect and analyze data from participants who will inform the refinement of SmokefreeSGM. In Phase 3, a feasibility trial will be conducted among 80 SGM smokers either enrolled in SmokefreeSGM or SmokefreeTXT, the original text-based program developed by the National Cancer Institute for the general population. Our research team will examine recruitment, retention, and smoking abstinence rates at 1-, 3-, and 6-month follow-up. Additionally, a qualitative interview will be conducted among 32 participants to evaluate the feasibility and acceptability of the programs (SmokefreeSGM and SmokefreeTXT)., Results: This study received approval from The University of Texas Health Science Center at Houston Committee for the Protection of Human Subjects to begin research on August 21, 2020. Recruitment for the beta testing of SmokefreeSGM (Phase 2) began in January 2022. We estimate that the feasibility trial (Phase 3) will begin in September 2022 and that results will be available in December 2023., Conclusions: Findings from this research effort will help reduce tobacco-related health disparities among SGM smokers by determining the feasibility and acceptability of SmokefreeSGM, an SGM-tailored smoking cessation intervention., Trial Registration: ClinicalTrials.gov NCT05029362; https://clinicaltrials.gov/ct2/show/NCT05029362., International Registered Report Identifier (irrid): DERR1-10.2196/42553., (©Irene Tami-Maury, Rebecca Klaff, Allison Hussin, Nathan Grant Smith, Shine Chang, Lorna McNeill, Lorraine R Reitzel, Sanjay Shete, Lorien C Abroms.

Background: Areca nut (AN) is an addictive substance consumed in the Southeast region and is highly associated with oral premalignant lesions and oral cancer. The impact of AN use in the United States (US) is largely unknown, but the products are readily available and probably used by a significant fraction of Asian immigrants or descendants living in the US. We aimed at assessing AN use prevalence among the Asian community in Houston, Texas., Methods: A cross-sectional questionnaire was used to interview adult individuals (≥ 18 years of age) who self-identified as Asian immigrants or descendants residing in Houston. Means, frequencies, and proportions were reported. Factors associated with AN use were evaluated using logistic regression., Results: We surveyed 275 individuals (58% women, 43% between 35-54 years old, 67% born outside of the US, and 6% concurrent smokers). Among respondents, 91% were familiar with AN products, 17% self-reported ever use of AN products in the US, and 31% had friends/family members who were AN ever users. AN use was significantly associated with being Indian Subcontinent immigrants or descendants (ISID) (OR = 3·9; CI: 1·10,13·81; p = 0·035) and having friends/family members using AN products (OR = 6·2; CI: 1·69, 22·69; p = 0·006)., Conclusions: Our findings provide quantitative data on the prevalence of AN ever use and context for future AN prevention and cessation interventions specific to the Southeast Asian groups living in the US mainland. This is crucial for the prevention and control of oral cancer and other detrimental conditions related to AN consumption., (© 2022. The Author(s).)

Background: Adolescent and young adult (AYA) patients with cancer are underrepresented on cancer clinical trials (CCTs), and most AYAs are treated in the community setting. Past research has focused on individual academic institutions, but factors impacting enrollment vary across institutions. Therefore, we examined the patterns of barriers and facilitators between high- and low-AYA enrolling community-based clinics to identify targets for intervention., Materials and Methods: We conducted 34 semi-structured interviews with stakeholders employed used at National Cancer Institute Community Oncology Research Program (NCORP) affiliate sites ("clinics"). Stakeholders (eg, clinical research associates, patient advocates) were recruited from high- and low-AYA enrolling clinics. We conducted a content analysis and calculated the percentage of stakeholders from each clinic type that reported the barrier or facilitator. A 10% gap between high- and low-enrollers was considered the threshold for differences., Results: Both high- and low-enrollers highlighted insufficient resources as a barrier and the presence of a patient eligibility screening process as a facilitator to AYA enrollment. High-enrolling clinics reported physician gatekeeping as a barrier and the improvement of departmental collaboration as a facilitator. Low-enrollers reported AYAs' uncertainty regarding the CCT process as a barrier and the need for increased physician endorsement of CCTs as a facilitator., Conclusions: High-enrolling clinics reported more barriers downstream in the enrollment process, such as physician gatekeeping. In contrast, low-enrolling clinics struggled with the earlier steps in the CCT enrollment process, such as identifying eligible trials. These findings highlight the need for multi-level, tailored interventions rather than a "one-size-fits-all" approach to improve AYA enrollment in the community setting., (© The Author(s) 2022.

Introduction: Early-onset of Electronic Nicotine Delivering Systems (ENDS) use puts users at higher risk of developing a regular ENDS use pattern and/or transitioning to combusted tobacco products. Previous studies on ENDS use among adolescents have not considered sexual orientation as a fluid trait that can change over time. Our objective was to evaluate whether ENDS initiation differed by sexual orientation in a longitudinal, population-based cohort of adolescents transitioning into young adulthood in Texas., Methods: Sample (n = 1712) was drawn from the Texas Adolescent Tobacco and Marketing Surveillance System (waves 5-11) and stratified into three groups, representing sexual orientation: (1) respondents who reported being heterosexuals at each wave (straight), (2) those who consistently self-identified as lesbian, gay or bisexual individuals (LGB), and (3) subjects who reported sexual orientation mobility across waves (mobile). Nonparametric models for interval-censored data were used to estimate the cumulative distribution of age at ENDS initiation by sexual orientation group. Cox models for interval-censored data were used to evaluate whether ENDS initiation varied by sexual orientation group after adjusting for sex assigned at birth, race/ethnicity, cohort, and socioeconomic status., Results: Compared to Straight adolescents, the risk of earlier-onset of ENDS use was higher among mobile individuals (HR = 1.43, 95% CI: 1.12 to 1.83) and LGB individuals (HR = 1.49, 95% CI: 1.13 to 1.98), respectively, after adjusting for sociodemographic risk factors. Differences between Straight adolescents and LGB/mobile individuals became more pronounced with increasing age., Conclusion: Analyzing sexual mobility overtime is necessary for understanding the risk associated with youth ENDS initiation and subsequent use., Implications: Future research should use more accurate sexual orientation assessments to explore further the relationship between sexual orientation mobility and early-onset Electronic Nicotine Delivering Systems (ENDS) use. Understanding the implications of sexual orientation mobility on ENDS initiation will be critical for developing inclusive public health programs aimed at preventing or delaying ENDS use and for providing practical recommendations at state and local levels., (© The Author(s) 2021.

Background: There is a dearth of literature on sexual and gender minority (SGM) only data that examines the association between tobacco use, co-occurring substance use, and psychological distress., Methods: Using SGM-only primary data collected between March 2016 and January 2017, participants were categorized based on recent tobacco use and prevalence estimates were calculated for exclusive e-cigarette use and use of other tobacco products. The strength of the association between tobacco use, recent hazardous alcohol use, illicit substance use, and having a diagnosis for depression, anxiety, or PTSD was estimated. Bivariate and adjusted multinomial logistic regression analyses were used to obtain estimates., Results: A third of participants (32.91%) reported recent tobacco use. Of these, 8.79% were exclusive e-cigarette users and 24.12% used other tobacco products. Compared to non-tobacco users, e-cigarette users were more likely to have recently used illicit drugs (RRR= 3.00 [1.89, 4.77]) and participated in a substance use treatment program (RRR= 7.98 [1.76, 36.15]). Participants categorized as using other tobacco products, when compared to non-tobacco users, were more likely to have recently used illicit drugs (RRR= 2.05 [1.46, 2.86]), engaged in hazardous drinking (RRR= 2.27 [1.63, 3.16]), and participated in a substance use treatment program (RRR= 9.53 [3.14, 28,88]). They were also more likely to have been recently diagnosed with PTSD (RRR= 3.40 [1.82, 6.34])., Conclusions: SGM tobacco users are more likely to engage in hazardous drinking and illicit substance use and access substance use treatment services. There is an opportunity to reduce tobacco use among SGM individuals by developing, implementing, and evaluating tailored tobacco cessation interventions within substance use treatment facilities., (Copyright © 2021 Elsevier B.V.

Background: Although it is well documented that adolescents and young adults (AYAs) with cancer have low participation in cancer clinical trials (CCTs), the underlying reasons are not well understood. We used the National Cancer Institute Community Oncology Research Program (NCORP) network to identify barriers and facilitators to AYA CCT enrollment, and strategies to improve enrollment at community-based and minority and/or underserved sites., Methods: We performed one-on-one semistructured qualitative interviews with stakeholders (NCORP site principle investigators, NCORP administrators, physicians involved in enrollment, lead clinical research associates or clinical research nurses, nurse navigators, regulatory research associates, patient advocates) in the AYA CCT enrollment process. NCORP sites that included high and low AYA-enrolling affiliate sites and were diverse in geography and department representation (eg, pediatrics, medical oncology) were invited to participate. All interviews were recorded and transcribed. Themes related to barriers and facilitators and strategies to improve enrollment were identified., Results: We conducted 43 interviews across 10 NCORP sites. Eleven barriers and 13 facilitators to AYA enrollment were identified. Main barriers included perceived limited trial availability and eligibility, physician gatekeeping, lack of provider and research staff time, and financial constraints. Main facilitators and strategies to improve AYA enrollment included having a patient screening process, physician endorsement of trials, an "AYA champion" on site, and strong communication between medical and pediatric oncology., Conclusions: Stakeholders identified several opportunities to address barriers contributing to low AYA CCT enrollment at community-based and minority and/or underserved sites. Results of this study will inform development and implementation of targeted interventions to increase AYA CCT enrollment., (© The Author(s) 2021. Published by Oxford University Press.)

Objective: Cancer care providers' (CCPs) attitudes towards smoking cessation are influenced by many factors, including their smoking status and knowledge. Our objective was to assess CCPs' characteristics, tobacco use and smoking cessation practices in two Latin American cancer centres., Design: Cross-sectional survey., Settings: Two urban cancer centres located in Colombia and Mexico., Participants: A total of 238 CCPs., Measures: Online survey consisted of 28 close-ended questions adapted from the 2012 International Association for the Study of Lung Cancer survey and the Global Adult Tobacco Survey developed by the WHO. Means, frequencies and proportions were reported for each country. Factors associated to providing of smoking cessation treatment or referral at initial visit were evaluated using logistic regression., Results: Current smoking prevalence was 10.5% and 12.3% among Colombian and Mexican CCPs, respectively. Around three quarters of the Colombian (86.4%) and Mexican CCPs (66.1%) considered to have inadequate training in smoking cessation. Approximately two-thirds of Colombian (67.5%) and Mexican CCPs (63.9%) reported always or most of the time asking patients about tobacco use during the initial visit. In Colombia and Mexico, the most relevant barriers for providing cessation services were (1) difficulties for motivating patients with cancer, (2) patient resistance in quitting smoking, (3) lack of local resources or referral centres for smoking cessation and (4) lack of training in smoking cessation. CCPs appointed at Instituto Nacional de Cancerología were less likely to provide cessation treatment or referral to their patients if they had less than 50% of their time devoted to patient care and were former or current smokers. The regression model for Instituto de Cancerología did not retain statistically significant variables., Conclusion: Our findings highlight an urgent need for assisting Latin American CCPs in their quitting efforts as well as expanding formal smoking cessation training specifically tailored to these professionals for improving patients' cancer prognosis and quality of life., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Importance: The population of cancer survivors is rapidly growing in the US. Tobacco smoking is associated with many cancers; however, whether cigarette smoking behaviors among cancer survivors vary according to cancer type-that is, smoking-related cancers (SRCs) vs non-smoking-related cancers (NSRCs)-remains unclear., Objectives: To examine cigarette smoking prevalence and behaviors (ie, continuing or quitting smoking) among cancer survivors and to compare them between survivors of SRCs and NSRCs., Design, Setting, and Participants: This study was a cross-sectional analysis of the 2017 National Health Interview Survey, a household survey of civilian US residents who were aged 18 years or older. The National Health Interview Survey is population based and is representative of the US population. Data analysis was performed from June to October 2019., Main Outcomes and Measures: The primary outcomes were prevalence of current cigarette smoking among cancer survivors and prevalence of continuing smoking and quitting smoking after a cancer diagnosis. Secondary outcomes included factors associated with continued smoking vs quitting smoking after a cancer diagnosis., Results: A total of 26 742 respondents (mean [SD] age, 50.97 [18.61] years; 14 646 women [51.76%]) to the 2017 National Health Interview Survey were included in this study. Of the 3068 individuals (9.42%) in the study population who had cancer, 589 (19.96%) were SRC survivors, 2297 (74.50%) were NSRC survivors, 168 (4.96%) were survivors of both SRC and NSRC, and the remaining 14 (0.58%) had missing information about the type of cancer. Four hundred forty-nine SRC survivors (54.08%) were women, compared with 1412 NSRC survivors (54.30%). Ninety-six SRC survivors (15.69%) and 151 NSRC survivors (7.99%) were younger than 45 years. Overall, 372 cancer survivors (13.16%) were current smokers. Current smoking prevalence was higher among survivors of SRCs (145 survivors [19.78%]) compared with NSRC survivors (251 survivors [10.63%]). Among cancer survivors, 309 current smokers at cancer diagnosis (43.96%) reported having successfully quit smoking and 372 (56.04%) reported continuing smoking. Among the continuing smokers, 176 (56.49%) reported an unsuccessful quit attempt in the last 12 months. After cancer diagnosis, SRC survivors had higher odds of continued smoking compared with NSRC survivors (odds ratio [OR], 2.10; 95% CI, 1.12-3.93; P = .02). Men (OR, 1.93; 95% CI, 1.05-3.57; P = .04), those with angina pectoris (OR, 5.40; 95% CI, 1.33-21.91; P = .02), and those with chronic bronchitis (OR, 2.55; 95% CI, 1.05-6.19; P = .04) had higher odds of continued smoking, whereas Hispanic participants (compared with non-Hispanic white participants: OR, 0.18; 95% CI, 0.05-0.68; P = .01) and married participants (compared with never married participants: OR, 0.33; 95% CI, 0.12-0.96; P = .04) had lower odds of continued smoking., Conclusions and Relevance: These findings suggest that compared with NSRC survivors, SRC survivors may be at higher risk of being cigarette smokers at cancer diagnosis and of continuing smoking afterward. Although smoking cessation interventions are critically important for all cancer survivors, special efforts should target survivors of SRCs.

Adolescents and young adults (AYAs) are underrepresented in cancer clinical trials (CCTs). Limited trial enrollment slows progress in improving survival rates and prevents the collection of valuable biospecimens. A systematic literature review was conducted to assess barriers and facilitators to AYA enrollment in CCTs and to identify opportunities to improve enrollment. The PubMed MEDLINE, Web of Science, Scopus, and PsycINFO databases were searched to identify studies relevant to AYA CCT enrollment. Eligibility criteria included the qualitative and/or quantitative evaluation of barriers and facilitators to AYA enrollment. One hundred fifty-five unique publications were identified; 13 were included in the final analysis. Barriers to AYA enrollment in CCTs included a lack of existing trials applicable to the patient population, limited access to available CCTs, and a lack of physician awareness of relevant trials. Facilitators of enrollment included optimizing the research infrastructure, improving the awareness of available CCTs among providers, and enhancing communication about CCTs between providers and patients. In conclusion, the limited available research reports institution- and patient-level barriers and facilitators to AYA CCT enrollment. Because of persistent disparities in AYA enrollment, there is an urgent need to further identify the barriers and facilitators to AYA CCT enrollment to determine actionable areas for intervention., (© 2019 American Cancer Society.)

Background: Guidelines of the American Cancer Society and US Preventive Services Task Force specify that colorectal cancer (CRC) screening using guaiac-based fecal occult blood test (FOBT)/fecal immunochemical test (FIT) should be done at home. We therefore examined the prevalence and correlates of CRC screening using FOBT/FIT in physicians' office vs at home., Methods: Analysis of 9493 respondents 50-75 years old from the Cancer Control Supplement of the 2015 National Health Interview Survey was conducted. Weighted multivariable logistic regression was used to identify the determinants of in-office vs home use of FOBT/FIT for CRC screening., Results: Of the overall sample of screening-eligible adults (n = 9403), only 937 (10.4%) respondents underwent CRC screening using FOBT/FIT within the past year; among this screening population, 279 (28.3%) respondents were screened in-office. We found that sociodemographic factors alone, not CRC risk factors, determined whether FOBT/FIT would be used in-office or at home. Hispanics had greater odds of being screened in-office using FOBT/FIT (aOR: 2.04; 95% CI: 1.05-3.99). Compared with those 50-59 years old, respondents 70-75 years old were less likely to be screened in-office using FOBT/FIT (aOR: 0.44, 95% CI: 0.25-0.79). Similarly, individuals residing in the Western region of the country had lower odds of in-office FOBT/FIT (aOR: 0.26; 95% CI: 0.11-0.58)., Conclusion: Amid low overall uptake rates of FOBT/FIT in the United States, in-physician office testing is high, indicative of a missed opportunity for effective screening and poor adherence of physicians to national guidelines. Sociodemographic factors are determinants of uptake of FOBT/FIT at home or in-office and should be considered in designing interventions aimed at providers and the general population., (© 2019 The Authors.

HIV-positive women are at elevated risk for developing cervical cancer. While emerging research suggests that gynecologic health care is underutilized by HIV-positive women, factors associated with adherence to Pap testing, especially among HIV-positive female smokers are not well known. We utilized baseline data from a smoking cessation trial and electronic medical records to assess Pap smear screening prevalence and the associated characteristics among the HIV-positive female participants (n = 138). 46 % of the women had at least 1 Pap test in the year following study enrollment. Multiple logistic regression analysis indicated that younger age, African American race, hazardous drinking, increased number of cigarettes smoked per day, and smoking risk perception were associated with non-adherence to Pap smear screening. Cervical cancer screening was severely underutilized by women in this study. Findings underscore the importance of identifying predictors of non-adherence and addressing multiple risk factors and behavioral patterns among HIV-positive women who smoke.

Background: People living with human immunodeficiency virus (HIV)/AIDS (PLWHA) have a substantially higher prevalence of cigarette smoking compared to the general population. In addition, PLWHA are particularly susceptible to the adverse health effects of smoking. Our primary objective was to design and test the efficacy over 12 months of a smoking cessation intervention targeting PLWHA., Methods: Participants were enrolled from an urban HIV clinic with a multiethnic and economically disadvantaged patient population. Participants received smoking cessation treatment either through usual care (UC) or counseling delivered by a cell phone intervention (CPI). The 7-day point prevalence abstinence was evaluated at 3, 6, and 12 months using logistic regression and generalized linear mixed models., Results: We randomized 474 HIV-positive smokers to either the UC or CPI group. When evaluating the overall treatment effect (7-day abstinence outcomes from 3-, 6-, and 12-month follow-ups), participants in the CPI group were 2.41 times (P = .049) more likely to demonstrate abstinence compared to the UC group. The treatment effect was strongest at the 3-month follow-up (odds ratio = 4.3, P < .001), but diminished at 6 and 12 months (P > .05)., Conclusions: Cell phone-delivered smoking cessation treatment has a positive impact on abstinence rates compared to a usual care approach. Future research should focus on strategies for sustaining the treatment effect in the long term.

This article reports the findings from an online survey of nursing faculty from the United States, Canada, Latin America, and Caribbean countries to identify their perceptions about global health competencies for undergraduate nursing students. A list of global health competencies for medical students developed by the Association of Faculties of Medicine of Canada Resource Group on Global Health and the Global Health Education Consortium was adapted for nurses and translated from English to Spanish and Portuguese. The competencies were divided into six subscales, and respondents rated each competency on a 4-point Likert scale, with high scores reflecting strong agreement that the competency was essential for undergraduate nursing students. E-mail invitations and links to the online survey were distributed using a nonprobability convenience sampling strategy. This article reports findings only from the respondents to the English and Spanish surveys. The final sample included 542 responses to the English survey and 51 responses to the Spanish survey. Cronbach's alpha reliability coefficients for the subscales ranged from .78 to .96. The mean values for all 6 subscales and for each of the 30 items were greater than 3.0 for the respondents to the Spanish survey, and the mean values for 27 of the items were greater than 3.0 for the respondents to the English survey. These findings suggest that respondents perceived the competencies as essential global health competencies for undergraduate nursing students in the Americas. Narrative comments written by respondents indicate additional competencies and specific concerns about adding additional content to an already full curricula. Results of this study can be used to guide faculty deliberations about global health competencies that should be incorporated in the nursing curricula., (Copyright © 2012 Elsevier Inc.
