The Association of Alcohol Outlet Density with Alcohol Intake: The Multiethnic Cohort

OBJECTIVE

Neighborhood characteristics have been shown to influence lifestyle behaviors. Here we characterized alcohol outlet density in Los Angeles County, California, and Hawaii and assessed the association of alcohol outlet density with self-reported alcohol intake in the Multiethnic Cohort.

METHOD

Participants (n=178,977) had their addresses geocoded, at cohort entry (1993-1996), and appended to block group-level alcohol outlet densities (on- and off-premises). Multinomial logistic regression was performed to assess the association between self-reported alcohol intake and on- and off-premise alcohol outlet densities by each state. Stratified analysis was conducted by sex, race, and ethnicity.

RESULTS

Overall, we did not find associations between alcohol outlet density and self-reported alcohol intake in Los Angeles County, but we found that on-premise alcohol outlets were associated with 59% (OR=1.59, 95% CI:1.29,1.96) increased odds of consuming >2 drinks per day in Hawaii. Women living in neighborhoods with high density of on-premise alcohol outlets (Los Angeles County OR=1.15, 95% CI: 0.95,1.40) and (Hawaii OR=2.07, 95% CI: 1.43,3.01) had an increased odds of >2 drinks per day.

CONCLUSION

This study suggests that neighborhood factors are associated with individual level behaviors and that there may be a need for multilevel interventions.

Increasing risk of hepatocellular carcinoma with successive generations in the United States among Mexican American adults: The Multiethnic Cohort

BACKGROUND

US-born Latinos have a higher incidence of hepatocellular carcinoma (HCC) than foreign-born Latinos. Acculturation to unhealthy lifestyle behaviors and an immigrant self-selection effect may play a role. In this study, the authors examined the influence of generational status on HCC risk among Mexican American adults.

METHODS

The analytic cohort included 31,377 self-reported Mexican Americans from the Multiethnic Cohort Study (MEC). Generational status was categorized as: first-generation (Mexico-born; n = 13,382), second-generation (US-born with one or two parents born in Mexico; n = 13,081), or third-generation (US-born with both parents born in the United States; n = 4914). Multivariable Cox proportional hazards regression was performed to examine the association between generational status and HCC incidence.

RESULTS

In total, 213 incident HCC cases were identified during an average follow-up of 19.5 years. After adjusting for lifestyle and neighborhood-level risk factors, second-generation and third-generation Mexican Americans had a 37% (hazard ratio [HR], 1.37; 95% confidence interval [CI], 0.98-1.92) and 66% (HR, 1.66; 95% CI, 1.11-2.49) increased risk of HCC, respectively, compared with first-generation Mexican Americans (p for trend = 0.012). The increased risk associated with generational status was mainly observed in males (second-generation vs. first-generation: HR, 1.60 [95% CI, 1.05-2.44]; third-generation vs. first-generation: HR, 2.08 [95% CI, 1.29-3.37]).

CONCLUSIONS

Increasing generational status of Mexican Americans is associated with a higher risk of HCC. Further studies are needed to identify factors that contribute to this increased risk.

Diet quality and risk of gastric adenocarcinoma: The Multiethnic Cohort

BACKGROUND

Certain dietary patterns (i.e., low intake of fruit/vegetables and high intake of salt and processed meats) have been associated with the risk of gastric cancer. However, it is unclear whether overall diet quality assessed by predefined indices that consider the complexity of dietary intake is associated with gastric cardia and distal adenocarcinoma.

OBJECTIVES

To examine the association of a variety of diet indices with the risk of gastric cardia and distal adenocarcinoma and assess whether there are any subgroups that may benefit from better diets to reduce the risk of gastric adenocarcinoma.

METHODS

Dietary indices of interest included the Alternative Healthy Index (AHEI)-2010, Healthy Eating Index (HEI)-2015, the Dietary Approach to Stop Hypertension, alternate Mediterranean diet (aMED), and the energy-adjusted Dietary Inflammatory Index.

RESULTS

After an average follow-up time of 19.2 years, there were 836 incident cases of gastric distal adenocarcinoma and 207 cases of gastric cardia adenocarcinoma. We did not observe any significant associations between the dietary indices and gastric cancer for either anatomic site. Among former aspirin users, we observed an inverse association between aMED with distal cancer (HRQ5 vs. Q1: 0.64; 95% CI: 0.33, 1.23; P-trend = 0.03). Never smokers, who showed high-quality diet according to AHEI-2010, exhibited a 40% decreased risk of gastric distal cancer compared with those with the poorest-quality AHEI-2010 diet (HRQ5 vs. Q1: 0.60; 95% CI: 0.41, 0.88; P-trend = 0.08).

CONCLUSIONS

In a multiethnic population, we did not observe overall significant associations between these dietary quality indices and risk of gastric cancer. However, among former aspirin users and never smokers, there could be a reduction of gastric distal adenocarcinoma risk with a higher adherence to a Mediterranean diet.

Abstract 737: Diet quality and risk of gastric adenocarcinoma: The Multiethnic Cohort

Background: Certain diet components (i.e. low intake of fruit/vegetables and high intake of salt and processed meats) have been associated with risk of gastric cancer. However, it is unclear whether overall diet quality assessed by pre-defined indices, that take into account the complexity of dietary intake, is associated with gastric cardia and distal adenocarcinoma particularly in a racially and ethnically diverse population. Our objectives are to 1) examine the association of a variety of diet quality indices with risk of gastric cardia and distal adenocarcinoma and 2) assess if there are any subgroups that may benefit from better diets to reduce risk of gastric adenocarcinoma.

Methods: The analysis included 176,752 men and women aged 45-75 from the Multiethnic Cohort (MEC), who were African American, Japanese American, Latino, Native Hawaiian, or White, and completed a quantitative food frequency questionnaire (QFFQ) at cohort entry. Incident cases of gastric cancer (cardia ICD-O-3 C16.0 and non-cardia adenocarcinoma C16.1-C16.6) were identified by linkages with the Surveillance, Epidemiology, and End Results (SEER) cancer registries. Dietary indices, Alternative Healthy Index-2010 (AHEI-2010), Healthy Eating Index-2015 (HEI-2015), Dietary Approach to Stop Hypertension (DASH) score, alternate Mediterranean Diet (aMED) score, and Dietary Inflammatory Index (DII®), were calculated from the QFFQ and categorized into quintiles. Multivariable Cox models were used to estimate the association between dietary indices and gastric cancer risk by anatomic site. Effect modification was assessed for distal cancer by sex, smoking status, and aspirin use.

Results: A total of 207 incident cases of gastric cardia and 836 incident cases of gastric non-cardia were identified during an average follow up of 19.2 years. We did not observe any significant associations between any of the dietary indices and gastric cancer for both cardia and non-cardia tumors. However, we observed effect modification by aspirin use for aMED (P for heterogeneity = 0.01) as well as for DII (P for heterogeneity = 0.02). Among ever aspirin users, we observed an inverse association between aMED (HRQ5 vs Q1: 0.82, 95% CI: 0.53-1.26, Ptrend = 0.03) with non-cardia cancer, and the association with DII® was borderline statistically significant for the trend test (HRQ5 vs Q1: 0.86, 95% CI: 0.57-1.29, Ptrend = 0.07).

Conclusion: In a multiethnic population, we did not observe overall significant associations between these dietary quality indices and risk of gastric cancer. However, among ever aspirin users there could be a reduction of gastric non-cardia adenocarcinoma risk with a higher adherence to a Mediterranean diet.

Examining Attitudes, Expectations, and Tobacco Cessation Treatment Outcomes Among Incarcerated Tobacco Smokers

People who are incarcerated have limited resources to help them quit tobacco smoking. This study assessed the association between baseline attitudes and expectations of the program with final smoking status as the outcome. A 6-week group-based counseling with nicotine patches was provided to incarcerated individuals to quit smoking. A cross-sectional survey was given at the first session. Questions surrounding attitudes such as interest, confidence, motivation, and expectations were used to assess associations with smoking cessation. Exhaled carbon monoxide (CO) levels were taken at each sessions. Participants were categorized as nonsmoking or continued smoking at a 6.0 parts per million (ppm) CO at their final session attended. Overall, 123 participants had a CO higher than 6.0 ppm or missed more than two sessions at their final session, and 54 had a CO under 6.0 ppm. A total of 102 participants completed the 6-week program. Differences among the two groups in exhaled CO began at Session 3 and continued throughout the study.

Exploring Tobacco and E-Cigarette Use among Queer Adults during the Early Days of the COVID-19 Pandemic

The purpose of this narrative study is to describe the vaping and smoking characteristics of Queer people ages 18-34 before March of 2020 and to better understand how the COVID-19 pandemic has impacted those behaviors since March of 2020. In total, 31 participants were screened. Thirteen participants were screened prior to the emergence of COVID-19, and 18 were screened when study protocols transitioned to a remote setting (pre and during). Of the 27 eligible participants, a total of 25 participants completed the study. Most participants (n = 13) self-identified as male, followed by five identified as female, four self-identified as gender non-binary, and three identified as transgender. The most common sexual orientation amongst participants was gay (n = 10), with bisexual being the second-most reported. Approximately 20 Queer participants reported using cigarettes, 14 participants self-reported using electronic devices, and 11 reported using hookah. Twenty participants reported smoking ten or less, and four self-reported using 11-20 cigarettes per day. Approximately, 92% of participants (n = 23) indicate that they are using an e-cigarette and regular cigarettes, and 57% of participants (n = 12) report using one pod or cartridge per day. The three themes that emerged in this study are: (1) Queer people during COVID-19 are experiencing heightened minority stress; (2) Queer people are unfamiliar with smoking cessation; and (3) vaping and smoking are attributed to stress and anxiety. Queer participants are likely to be dual users of cigarette and vaping products. This present study provides increasing evidence that Queer people are experiencing heightened stress and anxiety and using cigarette smoking and vaping to cope during the COVID-19 pandemic.

Abstract 2551: The development of cancer digital videos to increase participation in marginalized communities

Social media, in the form of digital videos, targeted people with limited health literacy, as well as disadvantaged or marginalized groups, may help reduce cancer health disparities and improve health outcomes in these populations. In this article, we document the process of adapting the content from the Cancer 101 curriculum to create animated scripts about the cancer care continuum that is clear, straightforward, and in plain language. The development of the Cancer 101 digital videos required a multidisciplinary collaboration from - public health, medicine, technology, and expertise in correctional health, smoking cessation, web development, video producers, and individuals directly impacted by cancer disparities. The Cancer 101 videos were showcased at a community health fair where the videos were viewed by attendants waiting to be seen by a medical provider. While waiting for their cancer screening, thirteen individuals were selected and invited to watch all eleven videos totaling less than 60-minutes of viewing time. Overall, participants agreed that they would recommend the videos to friends/family and that they plan to watch other video modules to learn more information about cancer. Additionally, participants enjoyed the graphics and audio of the videos presented. Furthermore, participants noted that Cancer 101 digital videos described cancer in plain language, leading to a better understanding of the disease. Future research is needed to implement Cancer 101 digital videos in healthcare clinics to increase cancer information and improve cancer screening rates in marginalized communities.

Oncotype DX Test Receipt among Latina/Hispanic Women with Early Invasive Breast Cancer in New Jersey: A Registry-Based Study

Oncotype DX® (ODX) is a valid test of breast cancer (BC) recurrence risk and chemotherapy benefit. The purpose of this study was to examine prevalence of and factors associated with receipt of ODX testing among eligible Latinas/Hispanics diagnosed with BC. Sociodemographic and tumor data of BC cases diagnosed between 2008 and 2017 among Latina/Hispanic women (n = 5777) were from the New Jersey State Cancer Registry (NJSCR). Eligibility for ODX testing were based on National Comprehensive Cancer Network guidelines. Multivariable logistic regression models of ODX receipt among eligible women were used to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CI) by demographic and clinicopathologic factors. One-third of Latinas/Hispanics diagnosed with BC were eligible for ODX testing. Among the eligible, 60.9% received ODX testing. Older age (AOR 0.08, 95% CI: 0.04, 0.14), low area-level SES (AOR 0.58, 95% CI: 0.42, 0.52), and being uninsured (AOR 0.58, 95% CI: 0.39, 0.86) were associated with lower odds of ODX testing. While there was relatively high ODX testing among eligible Latina/Hispanic women with BC in New Jersey, our findings suggest that age, insurance status, and area-level SES contribute to unequal access to genetic testing in this group, which might impact BC outcomes.

Evidence for the Confluence of Cigarette Smoking, Other Substance Use, and Psychosocial and Mental Health in a Sample of Urban Sexual Minority Young Adults: The P18 Cohort Study

BACKGROUND

Sexual minority men (SMM) and transgender women (TW) are more likely to smoke cigarettes than heterosexual and cisgender peers, which may exacerbate existing disparities in mental and psychosocial health and substance use.

PURPOSE

As few existing studies have examined the confluence of these factors, we sought to examine tobacco use in a diverse sample of SMM and TW and describe its relationship with other substance use and health.

METHODS

Data were drawn from a study of syndemic conditions among SMM and TW, which included measures assessing tobacco use, substance use, and mental, psychosocial, and general health.

RESULTS

A majority of the racially/ethnically and socioeconomically diverse sample (n = 665) reported ever smoking a cigarette, and more than half of them were current smokers. Current smoking was associated with more frequent recent substance use and poorer mental, psychosocial, and general health. In multivariable analyses, current smoking was predicted by more frequent substance use and more severe anxiety, when adjusting for demographic, substance use, and health factors.

CONCLUSIONS

A syndemic approach to health conditions such as substance use, mental health, and psychosocial burden dictates a framework of interrelation and mutual exacerbation. In doing so, we found that current cigarette use was associated with more frequent alcohol and marijuana use and more severe anxiety, suggesting a confluence of cigarette smoking, other substance use, and mental health burden. We recommend a holistic approach to treating tobacco use in sexual and gender minority populations that addresses both substance use and the myriad psychosocial burdens that sexual and gender minority communities experience.

The Development and Prototype Feedback of Digital Cancer 101 Videos to Enhance Cancer Education for Marginalized Communities With Limited Health Literacy

Social media, in the form of digital videos targeted to people with limited health literacy, as well as disadvantaged or marginalized groups, may help reduce cancer health disparities and improve health outcomes in these populations. In this article, we document the process of adapting the content from the Cancer 101 curriculum to create animated scripts about the cancer care continuum that is clear, straightforward, and in plain language. The development of the Cancer 101 digital videos required a multidisciplinary collaboration from-public health, medicine, technology, and expertise in correctional health, smoking cessation, web development, video producers, and individuals directly impacted by cancer disparities. The Cancer 101 videos were showcased at a community health fair where the videos were viewed by attendants waiting to be seen by a medical provider. While waiting for their cancer screening, 13 individuals were selected and invited to watch all 11 videos totaling less than 60-minutes of viewing time. They included 3 Latina women, 2 Latino men, and 8 Haitian women. All participants were between the ages of 40-65 years old. Overall, participants agreed that they would recommend the videos to friends/family (M = 4.77, SD = 0.44) and that they plan to watch other video modules to learn more information about cancer (M = 4.72, SD = 0.47). Additionally, participants enjoyed the graphics and audio of the videos presented (M = 4.85, SD = 0.38). Furthermore, participants noted that Cancer 101 digital videos described cancer in plain language, leading to a better understanding of the disease. Future research is needed to implement Cancer 101 digital videos in healthcare clinics to increase cancer information and improve cancer screening rates in marginalized communities.

Harnessing Digital Videos to Promote Cancer Prevention and Education: a Systematic Review of the Literature from 2013-2018

Social media has transformed the way cancer patients search for information about their chronic health problems. The purpose of this systematic review is to identify the use of online digital videos to increase cancer knowledge and to understand information preference, behavioral changes, and attitudes towards online cancer education videos. The databases used for this review included MedLine, PsychINFO, and PubMed. These medical databases were used to locate peer-reviewed academic journals from 2013-2018 using the following MeSH terms: "cancer education videos," "cancer prevention videos," and "cancer education digital videos." A total of 4996 articles were retrieved from the initial search, and 33 articles were reviewed. Articles were excluded if videos did not (1) focus on cancer education and prevention; (2) posted on an online platform; and (3) assessed participants' knowledge, attitude, or beliefs about cancer. Eleven articles were found to meet inclusion criteria for final review. All of the studies focused on increasing education on preventive health behaviors (i.e., sunscreen use, smoking, and diet) and/or early detection strategies (i.e., screening testing and/or self-skin exams). While online digital health videos have the potential to improve health outcomes, issues related to technology access and health literacy must be considered when developing online health education videos.

The Preliminary Efficacy and Feasibility of Group-Based Smoking Cessation Treatment Program for Incarcerated Smokers

Group-based tobacco dependence treatment has been known to help smokers to quit in general adult populations, but the feasibility and efficacy of this type of smoking cessation treatment in correctional settings remain uncertain. A 6-week group-based smoking cessation treatment with nicotine replacement therapy (NRT) in the form of nicotine patches was implemented in seven male prison facilities, in the Northeast, among smokers who were born biologically as male. Exhaled breath carbon monoxide (CO) levels were collected from participants at each session to confirm smoking status. Participants were evaluated at the 1-month post-group treatment follow-up to determine abstinence. Those who were lost to follow-up were recorded as continued smoking and not using NRT nicotine patches. The goal of the study was to explore the feasibility and preliminary efficacy of conducting a smoking cessation treatment program for incarcerated smokers. A total of 350 inmates were screened, 177 inmates were enrolled across the prison sites for the 6-week program, and 102 inmates completed the program. A majority of those enrolled reported that they began smoking when they were between 15 and 19 years of age (44.9%) and were smoking on average for 26 years. Less than half (21.3%) reported ever using electronic cigarettes at baseline and in Session 1,116 individuals who attended reported a median CO level of 18.0 parts per million (ppm). At a 1-month follow-up, 43 individuals reported a median CO level of 5.00 ppm. The study demonstrated preliminary efficacy and feasibility of group-based smoking cessation treatment with NRT nicotine patches in incarcerated smokers.

Abstract LB-252: Group-based smoking cessation treatment for incarcerated men: A pilot study

Introduction. Cigarette smoking is the leading cause of morbidity and mortality that contributes to over six million deaths worldwide and is projected to cause more than eight million deaths per year by 2030. Overall cigarette smoking rates in the United States (U.S.) is estimated at 14%, but this number increases to 50-83% of smokers within correctional populations.

Methods. Using a cohort study design, sixteen incarcerated male smokers from a Northeastern state maximum prison facility in the U.S. participated in a 4-week group-based smoking cessation treatment program with nicotine replacement therapy and a one-month follow-up period to determine quit behaviors and abstinence. The goal of this pilot study was to explore the feasibility, acceptability, and efficacy of a smoking cessation group treatment intervention for incarcerated smokers where tobacco products are permitted.

Results. In this feasibility study, the average age of participants enrolled was 43 (SD = 13.69), and their first incarceration was at 19 (SD = 7.30). The majority of the participants identified as African American/Black (62.5%), 31.3% identified as Caucasian/White, and 6.3% identified as Hispanic/Latino as their race/ethnicity. The average age where individuals started smoking was 13.8 (SD = 3.2) and the total number of years smoked is 25.6 (SD = 14.9). The mean of cigarettes smoked each day was 13.0 (SD = 9.8). More than half of the people in the study indicated that they relight their cigarettes. Additionally, the two brands that participants indicated as their favorite were Kite (18.8%) and Newport (68.8%). Of all the participants, 87.5% indicated that they smoked menthol cigarettes. Majority of the participants indicated the importance of quitting tobacco (8.80 ± 1.82) and that they had a very difficult time during their previous quit attempts (43.8%). Previous quit attempts included forced abstinence while in solitary confinement or administrative segregation. At the 4-week follow up period, half of the participants that were enrolled in the group-based smoking cessation treatment and completed the program indicated that they did not smoke or use tobacco in the past 7-days or since their initial quit date (50.0%).

Conclusion. Group-based smoking cessation treatment should be prioritized as an effective intervention to aid incarcerated smokers to quit smoking. This study builds upon our growing knowledge of tobacco dependence and smoking cessation treatment, with a focus on individuals involved in the criminal justice system.

The smoking behaviors of incarcerated smokers

To determine smoking behaviors, quit attempts, and cessation preferences among incarcerated smokers, a cross-sectional survey was given to a sample of inmates from three state prison facilities in the United States. A majority of Black smokers (62%) identified as smokers, and 38% identified as ex-smokers, as compared to 46.4 percent of smokers (and 53.6% of ex-smokers) in the non-Black group. There were significant differences in the number of cigarettes smoked per day with non-Black smokers smoking one pack (M = 20.44, standard deviation = 15.86) than Black smokers (M = 14.49, standard deviation = 13.43; t = −2.50, p = 0.014). Smoking cessation interventions are needed to reduce smoking during incarceration.

[Autopsy findings related to Down's syndrome: 101 cases]

OBJECTIVES

To analyze the spectrum of congenital malformations among fetuses with Down's syndrome sent for necropsy. Materials and methods. Necropsies following medical termination of pregnancy during the second and third trimester were performed during a 4 year period.

RESULTS

The incidence of each malformation was determined. Talipes equinovarus and aberrant lobation of the lung were present in 6% of cases. We are able to state precisely the incidence of 11 pairs of ribs: 11%.

CONCLUSION

A precise knowledge about Down's syndrome associated malformations is essential for genetic counselling. The exact incidence of each sign is important to lead ultrasound examination when this syndrome is revealed.
