Racial/ethnic and socioeconomic variations in duration of smoking: results from 2003, 2006 and 2007 Tobacco Use Supplement of the Current Population Survey

Exploring the Link between Altitude of Residence and Smoking Patterns in the United States

INTRODUCTION

Smoking-related diseases affect 16 million Americans, causing approximately 480,000 deaths annually. The prevalence of cigarette smoking varies regionally across the United States, and previous research indicates that regional rates of smoking-related diseases demonstrate a negative association with altitude. The purpose of this study was to determine the relationship between altitude and the prevalence of cigarette smoking by county (N = 3106) in the United States. We hypothesized that smoking prevalence among adults would be negatively associated with mean county altitude.

METHODS

A multivariate linear regression was performed to examine the relationship between county-level mean altitude and county smoking rate. Covariates were individually correlated with 2020 smoking data, and significant associations were included in the final model.

RESULTS

The multivariate linear regression indicated that the county-level smoking rates are significantly reduced at high altitudes (p < 0.001). The model accounted for 89.5% of the variance in smoking prevalence, and for each 1000-foot increase in altitude above sea level, smoking rates decreased by 0.143%. Based on multivariate linear regression, the following variables remained independently and significantly associated: race, sex, educational attainment, socioeconomic status, unemployment, physical inactivity, drinking behavior, mental distress, and tobacco taxation.

CONCLUSIONS

Our results indicate that smoking rates are negatively associated with altitude, which may suggest that altitude affects the pharmacokinetics, pharmacodynamics, and mechanistic pathways involved in cigarette use. Further research is needed to explore the relationship between altitude and smoking and how altitude may serve as a protective factor in the acquisition and maintenance of tobacco use disorders.

Assessing the impact of socioeconomic status on incidental lung nodules at an urban safety net hospital

INTRODUCTION

Lower socioeconomic status has been identified as an emerging risk factor for health disparities, including lung cancer outcomes. Most research investigating these outcomes includes patients from formal lung cancer screening programs. There is a paucity of studies assessing the relationship between socioeconomic status and incidental lung nodules. This study aimed to investigate the association between socioeconomic status and the size of incidental lung nodules on initial presentation at an urban safety net hospital, which did not have a formal lung cancer screening program or incidental lung nodule program.

METHODS

A retrospective chart review was conducted on patients with incidental lung nodules on CT chest imaging who were referred from primary care to a pulmonology clinic at a safety net hospital. Patients with incomplete nodule characteristics information were excluded. Data on demographics, comorbidities, smoking history, insurance type, immigration status, and geographical factors were collected. Less commonly studied determinants such as crime index, cost of living, and air quality index were also assessed. Logistic regression analysis was performed to assess relationships between nodule size and socioeconomic determinants.

RESULTS

Out of 3,490 patients with chest CT scans, 268 patients with ILNs were included in the study. 84.7% of patients represented racial or ethnic minorities, and most patients (67.8%) had federal insurance. Patients with non-commercial insurance were more likely to have larger, inherently higher-risk nodules (> 8 mm) compared to those with commercial insurance (OR 2.18, p 0.01). Patients from areas with higher unemployment rates were also less likely (OR 0.75, p 0.04) to have smaller nodules (< 6 mm). Patients representing racial or ethnic minorities were also more likely to have nodules > 8 mm (OR 1.6, p 0.24), and less likely to have nodules < 6 mm (OR 0.6, p 0.32), however, these relationships were not statistically significant.

CONCLUSION

This study found that lower socioeconomic status, indicated by having non-commercial insurance, was associated with larger incidental lung nodule size on initial presentation. While it is established that socioeconomic status is associated with disparities in lung cancer screening, these findings suggest that inequalities may also be present in those with incidental lung nodules. Further research is needed to understand the underlying mechanisms and develop interventions to address these disparities in incidental lung nodule evaluation and improve outcomes.

Birth Cohort‒Specific Smoking Patterns by Family Income in the U.S

INTRODUCTION

In the U.S., low-income individuals generally smoke more than high-income individuals. However, detailed information about how smoking patterns differ by income, especially differences by birth cohort, is lacking.

METHODS

Using the National Health Interview Survey 1983-2018 data, individual family income was calculated as a ratio of the federal poverty level. Missing income data from 1983 to 1996 were imputed using sequential regression multivariate imputation. Age‒period‒cohort models with constrained natural splines were used to estimate annual probabilities of smoking initiation and cessation and smoking prevalence and intensity by gender and birth cohort (1900-2000) for 5 income groups: <100%, 100%-199%, 200%-299%, 300%-399%, and ≥400% of the federal poverty level. Analysis was conducted in 2020-2021.

RESULTS

Across all income groups, smoking prevalence and initiation probabilities are decreasing by birth cohort, whereas cessation probabilities are increasing. However, relative differences between low- and high-income groups are increasing markedly, such that there were greater declines in prevalence among those in high-income groups in more recent cohorts. Smoking initiation probabilities are lowest in the ≥400% federal poverty level group for males across birth cohorts, whereas for females, this income group has the highest initiation probabilities in older cohorts but the lowest in recent cohorts. People living below the federal poverty level have the lowest cessation probabilities across cohorts.

CONCLUSIONS

Smoking prevalence has been decreasing in all income groups; however, disparities in smoking by family income are widening in recent birth cohorts. Future studies evaluating smoking disparities should account for cohort differences. Intervention strategies should focus on reducing initiation and improving quit success among low-income groups.

Food Insecurity and Depression among US Adults: NHANES 2005-2016

A growing body of evidence suggests that food insecurity is associated with adverse mental health outcomes such as depression and anxiety. In this study, the relationship between food insecurity and depression was examined using data from the 2005−2016 National Health and Nutrition Examination Survey (NHANES). Food insecurity was assessed with the 18-item United States Food Security Survey Module with zero affirmative responses indicating high food security, 1 or 2 affirmative responses indicating marginal food security, and ≥3 affirmative responses indicating food insecurity. Depression was assessed with the Patient Health Questionnaire-9 with scores ≥10 indicating depression. Data were analyzed from 28,448 adult participants aged 20 or older. Food insecurity was present in 19.2% of the sample population (n = 5452). Food security status was significantly associated with gender, race, education level, marital status, smoking status, and BMI (Rao-Scott chi-square, p < 0.05). Fully food secure and very low food security adults experienced depression at a rate of 5.1% and 25.8%, respectively (Rao-Scott chi-square, p < 0.0001). Participants with very low food security had a significantly greater odds of depression than food secure adults, OR = 3.50 (95% CI: 2.98, 4.12). These findings suggest that food insecurity is a significant risk factors for depression in US adults over 20 years of age. To address this issue in our citizenry, police initiatives and public health interventions addressing both food access and mental health should be prioritized.

Tobacco-related health inequalities among Black Americans: A narrative review of structural and historical influences

We conducted a narrative literature review to examine contributing factors of disparities in tobacco usage and outcomes affecting Black Americans. We propose potential solutions that can be used to effectively address these disparities. We identified historical factors; socioeconomic factors; targeted marketing/advertising; the influence of racism/discrimination; neighborhood socioeconomic disadvantage; and mass incarceration. We call for more thorough examinations of these factors as a key element of tobacco-focused research and interventions to eliminate the disproportionate burdens faced by Black Americans. We advocate for greater emphases on the impacts of personal and structural racism on tobacco usage and outcomes affecting Black Americans.

Hispanic/Latinx ethnic subgroup differences in sociodemographic, sociocultural, and smoking characteristics in a cessation trial: An exploratory study

INTRODUCTION

Hispanic/Latinx smokers in the United States are often treated as a homogeneous group. However, population-based studies suggest cigarette use differs among Hispanic/Latinx subgroups by sociodemographic or sociocultural characteristics. This secondary analysis aimed to advance the limited literature by examining differences in smoking-related variables.

METHODS

We used baseline data from a randomized controlled trial testing a self-help Spanish-language smoking cessation intervention. Puerto Rican (PR), Mexican, and Cuban, the three largest Hispanic/Latinx subgroups in the sample (N=1028), were first compared on sociodemographic and sociocultural variables (acculturation and familism). Primary analyses assessed subgroup differences in cigarette use variables [e.g., cigarettes per day (CPD), nicotine dependence (Fagerström Test for Nicotine Dependence), daily smoking] and smoking-related cognitive constructs (motivation to quit, smoking outcome expectancies and abstinence self-efficacy) controlling for sociodemographic and sociocultural variables. Additional analyses explored differences between men and women within subgroups.

RESULTS

Mexicans exhibited the lowest levels of daily smoking (90% vs. 95% Cubans and 96% PR; p=.001), CPD (M=13.5, SD=9.5 vs. M=20.1, SD=9.9 Cubans and M=16.7, SD=10.1 PR; p=.016), and nicotine dependence (M=4.2, SD=2.3 vs. M=6.0, SD=2.1 Cubans and M=5.7, SD=2.2 PR; p< .001), with no differences between PRs and Cubans. Within-subgroup comparisons between men and women showed the most differences among PRs [e.g., men were more nicotine dependent (M=6.0, SD=1.9) than women (M=5.4, SD=2.3; p=.041)] and Cubans [e.g., men smoked more CPD (M=22.2, SD=12.2) than women (M=19.3, SD=12.0; p=.042)], and the fewest among Mexicans.

CONCLUSIONS

Findings support heterogeneity within Hispanic/Latinx smokers and highlight the potential utility of examining sociodemographic, sociocultural, and smoking characteristics important for developing salient cessation interventions.

IMPLICATIONS

Findings demonstrate that treatment-seeking Hispanic/Latinx smokers in the US differ in sociodemographic, sociocultural, and smoking-related variables (cigarette use and smoking-related cognitive constructs) by subgroup (i.e., Puerto Rican, Mexican, Cuban) and within subgroups by sex. These differences suggest that heterogeneity among subgroups should be considered when developing cessation interventions for Hispanics/Latinxs. Future research should examine how differences in sociodemographic and smoking-related variables impact intervention outcomes and explore the role of sociocultural factors (e.g., acculturation and familism) as determinants of cessation.

Sociodemographic Patterns of Exclusive and Dual Combustible Tobacco and E-Cigarette Use among US Adolescents-A Nationally Representative Study (2017-2020)

This study assessed the sociodemographic predictors of exclusive and dual use of the most frequently used nicotine/tobacco products, e-cigarettes, and combustible tobacco among adolescents. Cross-sectional data was from the 2017-2020 Monitoring the Future nationally representative study of eighth, tenth, and twelfth-grade students. We coded past 30 day nicotine/tobacco use into four mutually exclusive categories: no use, e-cigarette use only, combustible use (cigarette or cigar) only, and dual use (e-cigarette and combustible). We pooled the 2017-2020 data to examine the relationship between sex, race/ethnicity, parental education, and each product-use category using multinomial logistic regression, stratified by grade level. Among eighth (N = 11,189), tenth (N = 12,882), and twelfth graders (N = 11,385), exclusive e-cigarette use was the most prevalent pattern (6.4%, 13.2%, 13.8%, respectively), followed by dual use (2.7%, 4.5%, 8.9%), and exclusive combustible use (1.5%, 2.5%, 5.3%). eighth and tenth-grade adolescents whose highest parental education was a 4-year college degree or more had lower odds of exclusive combustible and dual use when compared to adolescents whose highest parental education was less than a high school degree. Research should continue to monitor the differential use of combustible tobacco products and e-cigarettes among adolescents from low socioeconomic status backgrounds or racial/ethnic minority households to inform ongoing and future interventions or policies.

Public Housing Resident Perspectives on Smoking, Barriers for Smoking Cessation, and Changes in Smoking Mandates

Background

Individuals from low-income groups report disproportionate rates of cigarette use, secondhand smoke (SHS) exposure with increased morbidity and mortality. Smoking bans in public housing have been enacted in attempt to reduce tobacco use and SHS exposure among lower income individuals. This study investigated the support needs of tobacco users living in two public housing complexes in Detroit, Michigan (USA), including their perspectives on smoking, resources and barriers for smoking cessation, and the impact of policy changes.

Methods

This is a mixed-methods study, using a qualitative focus groups approach and a short survey, public housing residents interview data was analyzed to explore themes related to smoking-related issues. Specifically, six themes were assessed across four focus groups: (1) Quitting Smoking, (2) Current Smoking Cessation Resources, (3) Legal Mandates, (4) Education and Perceptions of Smoking, (5) Community Needs and Barriers, and (6) Medical Experiences.

Results

There were 59 participants; the majority (39/42, 93%) of smokers reported at least one quit attempt. During the focus groups, several participants indicated a desire to quit smoking but reported barriers to smoking cessation, such as lack of access to medications, social triggers to continue smoking, and socioeconomic stressors. A number of suggestions were provided to improve smoking cessation resources, including support groups, graphic images of smoking-related diseased tissue, and better communication with health care providers.

Conclusions

These findings demonstrate smoking bans in two public housing complexes can be effective yet are dependent upon a complex set of issues, including numerous barriers to care.

Evaluating the feasibility and acceptability of a mobile-based health technology for smoking cessation: Mobile Anxiety Sensitivity Program

OBJECTIVES

Cigarette smoking is the leading preventable cause of death and disability. Although most US smokers want to quit, more than 95% of cessation attempts end in relapse within 6 months. To improve cessation outcomes, research has turned to targetable mechanisms, such as anxiety sensitivity (AS), which maintain smoking behaviour, impede cessation success, and can be effectively targeted in the context of psychosocial interventions. Although integrated treatment programmes that address AS reduction in the context of smoking cessation have demonstrated promising results, presently, no mobile, technology-based integrated treatment exists to expressly address smoking and AS. The current study evaluated the initial feasibility and acceptability of a mobile smoking cessation intervention, Mobile Anxiety Sensitivity Program for smoking (MASP).

METHODS

Participants were 15 daily adult combustible cigarette smokers (females n = 6, M_age  = 46.5 years, SD = 13.3) who completed a 6-week total intervention period (baseline visit, 2 weeks pre-quit, 4 weeks post-quit, follow-up visit).

RESULTS

Most participants (N = 12) completed the full 6-week intervention, and participant engagement with MASP was high. Participants reported that MASP was acceptable. Biochemical verification of smoking abstinence indicated 25% of smokers were abstinent for at least 24 hr prior to the in-person 4 weeks post-quit follow-up visit.

CONCLUSIONS

Findings indicated that MASP has the potential to provide effective assistance to those wanting to quit cigarettes.

PRACTITIONER POINTS

Mobile-based smoking cessation interventions may be a promising treatment option, particularly for those of lower socio-economic status. Targeting AS in the context of a mobile-based smoking cessation app may be a viable way to improve smoking cessation success and treatment outcome. Due to the pilot nature of this study, there was no control group. Thus, comparative conclusions and generalizability based on the current study must be made with caution.

Mobile Health Tobacco Cessation Interventions to Promote Health Equity: Current Perspectives

Although US tobacco use trends show overall improvement, social disadvantage continues to drive significant disparities. Traditional tobacco cessation interventions and public policy initiatives have failed to equitably benefit socially-disadvantaged populations. Advancements in mobile digital technologies have created new opportunities to develop resource-efficient mobile health (mHealth) interventions that, relative to traditional approaches, have greater reach while still maintaining comparable or greater efficacy. Their potential for affordability, scalability, and efficiency gives mHealth tobacco cessation interventions potential as tools to help redress tobacco use disparities. We discuss our perspectives on the state of the science surrounding mHealth tobacco cessation interventions for use by socially-disadvantaged populations. In doing so, we outline existing models of health disparities and social determinants of health (SDOH) and discuss potential ways that mHealth interventions might be optimized to offset or address the impact of social determinants of tobacco use. Because smokers from socially-disadvantaged backgrounds face multi-level barriers that can dynamically heighten the risks of tobacco use, we discuss cutting-edge mHealth interventions that adapt dynamically based on context. We also consider complications and pitfalls that could emerge when designing, evaluating, and implementing mHealth tobacco cessation interventions for socially-disadvantaged populations. Altogether, this perspective article provides a conceptual foundation for optimizing mHealth tobacco cessation interventions for the socially-disadvantaged populations in greatest need.

Self-help smoking cessation intervention for Spanish-speaking Hispanics/Latinxs in the United States: A randomized controlled trial

BACKGROUND

Hispanic/Latinx smokers living in the United States face unique challenges in quitting smoking. This study evaluated the efficacy of a culturally relevant, Spanish-language, extended self-help smoking cessation intervention among Hispanic smokers.

METHODS

A 2-arm parallel randomized controlled trial was conducted with Hispanic/Latinx smokers living in the United States who preferred health information in Spanish and smoked 5 or more cigarettes per week. Participants were randomly allocated to receive Libre del Cigarrillo (LDC), which consisted of 11 booklets and 9 pamphlets mailed monthly over 18 months, or the usual care (UC), which was a single Spanish-language self-help booklet from the National Cancer Institute. The primary outcome was self-reported 7-day point prevalence smoking abstinence assessed 6, 12, 18, and 24 months after the baseline. Eight prespecified moderators of the intervention were evaluated. Cost-effectiveness was also evaluated. All statistical tests were 2-sided.

RESULTS

Data from all participants randomized to LDC (n = 714) or UC (n = 703) were used for analyses after multiple imputation to manage missing data. Generalized estimating equation analyses indicated that LDC abstinence rates were higher (P < .001) across all assessments. Logistic regression analyses revealed that at 24 months, the abstinence rate was greater for LDC (33.1%) than UC (24.3%; odds ratio, 1.54; 95% confidence interval, 1.18-2.02; P = .002). Men exhibited a strong intervention effect at all assessments (P values < .001), whereas the intervention effect for women was observed only at 6 and 12 months (P values < .018). In comparison with UC, the incremental cost per quitter in the LDC arm was $648.43 at 18 months and $683.93 at 24 months.

CONCLUSIONS

A culturally relevant, Spanish-language intervention was efficacious and cost-effective for smoking cessation.

LAY SUMMARY

Research is needed to develop interventions for ethnic minority smokers. The aim of the current study was to test a Spanish-language adaptation of a validated and easily implemented self-help smoking cessation intervention in a nationwide randomized controlled trial. The findings demonstrated that the intervention produced greater smoking abstinence in comparison with a standard self-help booklet. Participants also were more satisfied with the intervention, and it was cost-effective. Efforts aimed at promoting tobacco abstinence in this underserved population could have significant public health implications, including potential reductions in cancer health disparities associated with tobacco smoking.

Regional Effects of Perceived Risks of Harm on Cigarette Smoking among U.S. High School Seniors: Evidence from Monitoring the Future

Overall, there has been an increasing trend in the perceived risk of harm from smoking among U.S. high school seniors. However, these perceptions of risk have been falling in recent years. This study uses regional-level panel data from the Monitoring the Future survey and a fixed effects model to estimate the effect of perceived risk on three regional measurements of smoking behavior: consumption, lifetime prevalence, and daily smoking prevalence. Elasticity measurements at regional levels show that an increase in perceived risk decreases these regional measurements of smoking behavior. Moreover, the results show that, at regional levels, these measurements of smoking behavior are more responsive to changes in the perceived risk associated with smoking than to changes in the price of cigarettes.

Prevalence Trend and Disparities in Rheumatoid Arthritis among US Adults, 2005-2018

Rheumatoid arthritis (RA) trends among US adults and disparities in RA patients in recent years have not been well described. We aimed to examine the trend of RA prevalence and disparities among US adults. Data from the National Health and Nutrition Examination Survey (NHANES) of the years 2005–2018 were analyzed to examine the self-reported RA prevalence trend. Age-adjusted RA prevalence stratified by race/ethnicity and socioeconomic status (SES), as well as associated linear trends, were calculated for both genders. The multivariable adjustment was used to evaluate the association between race, SES, and RA. During 2005–2018, there was no significant linear trend in the age-adjusted self-reported RA prevalence among men and women, but significant differences among people from different races, educational levels, and family poverty income ratio (PIR) groups were observed. The RA rate difference was significant for both genders and between Non-Hispanic Caucasians and Non-Hispanic African Americans (both p-value ≤ 0.001). Both men and women with a higher educational level and a higher PIR had a lower age-adjusted RA rate. Age-adjusted RA prevalence fluctuated for both men and women during 2005–2018. Non-Hispanic African Americans and people with low SES had significantly higher age-adjusted RA prevalence and RA risk.

The impact of income and education on lung cancer screening utilization, eligibility, and outcomes: a narrative review of socioeconomic disparities in lung cancer screening

Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths in the US and worldwide. In particular, vulnerable populations such as those of low socioeconomic status (SES) are at the highest risk for and suffer the highest mortality from NSCLC. Although lung cancer screening (LCS) has been demonstrated to be a powerful tool to lower NSCLC mortality, it is underutilized by eligible smokers, and disparities in screening are likely to contribute to inequities in NSCLC outcomes. It is imperative that we collect and analyze LCS data focused on individuals of low socioeconomic position to identify and address barriers to LCS utilization and help close the gaps in NSCLC mortality along socioeconomic lines. Toward this end, this review aims to examine published studies that have evaluated the impact of income and education on LCS utilization, eligibility, and outcomes. We searched the PubMed, Ovid MEDLINE, and CINAHL Plus databases for all studies published from January 1, 2010, to October 21, 2020, that discussed socioeconomic-based LCS outcomes. The review reveals that income and education have impact on LCS utilization, eligibility, false positive rates and smoking cessation attempts; however, there is a lack of studies evaluating the impact of SES on LCS follow-up, stage at diagnosis, and treatment. We recommend the intentional inclusion of lower SES participants in LCS studies in order to clarify appropriate eligibility criteria, risk-based metrics and outcomes in this high-risk group. We also anticipate that low SES smokers and their providers will require increased support and education regarding smoking cessation and shared decision-making efforts.

Randomised pilot trial of cash incentives for reducing paediatric asthmatic tobacco smoke exposures from maternal caregivers and members of their social network

BACKGROUND

The primary aim was to evaluate the efficacy of financial incentives for reducing paediatric tobacco smoke exposures (TSEs) through motivating cigarette usage reduction among low-income maternal caregivers and members of their social network.

DESIGN

Randomised control pilot trial over a 6-month study follow-up time period. The study was undertaken from May 2017 to -May 2018. Once monthly follow-up visits occurred over the 6-month study period.

SETTING

Baltimore City, Maryland, USA.

PARTICIPANTS

We grouped 135 participants into 45 triads (asthmatic child (2-12 years of age), maternal caregiver and social network member). Triads were assigned in a 1:1 allocation ratio. The maternal caregiver and social network members were active smokers and contributed to paediatric TSE.

INTERVENTIONS

Triads were randomised to receive either usual care (TSE education and quitline referrals) or usual care plus financial incentives. Cash incentives up to $1000 were earned by caregivers and designated social network participants. Incentives for either caregivers or social network participants were provided contingent on their individual reduction of tobacco usage measured by biomarkers of tobacco usage. Study visits occurred once a month during the 6-month trial.

MAIN OUTCOME MEASURES

The main outcome measure was mean change in monthly paediatric cotinine levels over 6 months of follow-up interval and was analysed on an intention-to-treat basis.

RESULTS

The mean change in monthly child cotinine values was not significantly different in the intervention cohort over the 6-month follow-up period, compared with the control group (p=0.098, CI -0.16 to 1.89). Trends in child cotinine could not be ascribed to caregivers or social network members. Despite decreasing mean monthly cotinine values, neither the intervention cohort's caregivers (difference in slope (control-intervention)=3.30 ng/mL/month, CI -7.72 to 1.13, p=0.144) or paired social network members (difference in slope (control-intervention)=-1.59 ng/mL/month, CI -3.57 to 6.74, p=0.546) had significantly different cotinine levels than counterparts in the control group.

CONCLUSIONS

Financial incentives directed at adult contributors to paediatric TSE did not decrease child cotinine levels.

Tobacco use and associated factors among adults reside in Arba Minch health and demographic surveillance site, southern Ethiopia: a cross-sectional study

BACKGROUND

Tobacco use is one of the world-leading preventable killers. There was a varied prevalence of tobacco use and cigarette smoking across different areas. The aim of the study was to assess the prevalence and factors associated with current tobacco use among adults residing in Arba Minch health and demographic surveillance site (HDSS).

METHODS

A community-based cross-sectional study was conducted among adults residing in Arba Minch HDSS in 2017. The estimated sample size was 3368 individuals which were selected by simple random sampling techniques using Arba Minch HDSS dataset. Data collection tools were obtained from the WHO STEPwise. Current use of tobacco, which defined as the current use of smoked and/or smokeless tobacco, was considered as the dependent variable. A binary logistic regression model was used to identify candidate variables for the multivariable logistic regression model. An adjusted odds ratio (AOR) at a p-value of less than 0.05 was used to determine a statistically significant association between independent and dependent variables.

RESULT

The prevalence of tobacco use among adults was 20.2% (95% CI: 18.9-21.6%). The current use of smoked and smokeless tobacco were 17.1% (95%CI: 15.8-18.4%) and 9.7% (95%CI: 8.8-10.8%), respectively. The current use of tobacco was significantly associated with sex (female [AOR 0.54; 95%CI: 0.42-0.68] compared to men), age group (35-44 [AOR 1.57; 95%CI: 1.14-2.17], 45-54 [AOR 1.99; 95%CI: 1.45-2.74], and 55-64 [AOR 3.26; 95%CI: 2.37-4.48] years old compared to 25-35 years old), physical activity (moderate physical activity level [AOR 0.65; 95%CI: 0.44-0.96] compared with low) and residency (highland [AOR 4.39; 95% CI: 3.21-6.01] compared with at lowlander). Also, heavy alcohol consumption (AOR 3.97; 95% CI: 3.07-5.12), and Khat chewing (AOR 3.07(95%CI: 1.64-5.77) were also associated with the use of tobacco among the study participants.

CONCLUSION

Nearly one in five adults used tobacco currently in the study area, which is more than the national reports. Interventions for the reduction of tobacco use need to give due attention to men, older adults, uneducated, poor, and highlanders.

Comparing recruitment strategies for a digital smoking cessation intervention: Technology-assisted peer recruitment, social media, ResearchMatch, and smokefree.gov

BACKGROUND

Choosing the right recruitment strategy has implications for the successful conduct of a trial. Our objective was to compare a novel peer recruitment strategy to four other recruitment strategies for a large randomized trial testing a digital tobacco intervention.

METHODS

We compared enrollment rates, demographic and baseline smoking characteristics, and odds of completing the 6-month study by recruitment strategy. Cost of recruitment strategies per retained participant was calculated using staff personnel time and advertisement costs.

FINDINGS

We enrolled 1487 participants between August 2017 and March 2019 from: Peer recruitment n = 273 (18.4%), Facebook Ads n = 505 (34%), Google Ads = 200 (13.4%), ResearchMatch n = 356 (23.9%) and Smokefree.govn = 153 (10.3%). Mean enrollment rate per active recruitment month: 1) Peer recruitment, n = 13.9, 2) Facebook ads, n = 25.3, 3) Google ads, n = 10.51, 4) Research Match, n = 59.3, and 5) Smokefree.gov, n = 13.9. Peer recruitment recruited the greatest number of males (n = 110, 40.3%), young adults (n = 41, 14.7%), participants with a high school degree or less (n = 24, 12.5%) and smokers within one's social network. Compared to peer recruitment (retention rate = 57%), participants from Facebook were less likely (OR 0.46, p < 0.01, retention rate = 40%), and those from ResearchMatch were more likely to complete the study (OR 1.90, p < 0.01, retention rate = 70%). Peer recruitment was moderate in cost per retained participant ($47.18) and substantially less costly than Facebook ($173.60).

CONCLUSIONS

Though peer recruitment had lower enrollment than other strategies, it may provide greater access to harder to reach populations and possibly others who smoke within one's social network while being moderately cost-effective. ClinicalTrials.gov: NCT03224520.

Trends in Tobacco Use among Young Adults Presenting for Military Service in the United States Air Force between 2013 and 2018

Background: The US military has historically higher tobacco use compared to civilians, and tobacco use increases following enlistment. While the military is vulnerable to tobacco use, current surveillance of tobacco among this high-risk population is lacking. Methods: Recently enlisted Airmen (N = 43,597) between 2013 and 2018 were asked about tobacco use prior to enlistment across ten products: (1) cigarettes/roll your own tobacco, (2) smokeless tobacco/snus, (3) cigars, cigarillos/little cigars, (4) hookah/pipe, and (5) e-cigarettes. Results: Hookah/pipe use, cigarettes/roll your own, smokeless tobacco/snus, and cigars/little cigars/cigarillos use decreased significantly between 2013 and 2018, while the prevalence of e-cigarette use increased (p's < 0.0001). The relationships between the time and each tobacco product(s) use outcomes were influenced differently by different age, race, education and marital status. Conclusion: While e-cigarette use has increased in the civilian sector, the use of e-cigarettes among new recruits increased much more drastically (i.e. prevalence 15.3% in 2018). Further, demographic characteristics influenced tobacco trends; specifically, recruits of racial minorities increased their use of e-cigarettes over the past five years faster than Whites. Of concern is what impact this dramatic increase in e-cigarette use will have on overall health and later initiation of combustible tobacco products in the military.

Linkage of Maternal Caregiver Smoking Behaviors on Environmental and Clinical Outcomes of Children with Asthma: A Post-Hoc Analysis of a Financial Incentive Trial Targeting Reduction in Pediatric Tobacco Smoke Exposures

(1) Background: Monthly variability in smoking behaviors in caregivers of pediatric asthmatics yields questions of how much and when does smoking reduction result in improved environmental and clinical outcomes. (2) Methods: Post hoc analysis of data from a 6 month pilot randomized-control trial occurring from May 2017 to May 2018 in Baltimore City (MD, USA). The initial trial’s primary intervention explored the utility of financial incentives in modifying caregiver smoking behaviors. Post hoc analyses examined all dyads independent of the initial trial’s randomization status. All caregivers received pediatric tobacco smoke harm reduction education, in addition to monthly encouragement to access the state tobacco quitline for individual phone-based counseling and nicotine replacement therapy. Maternal caregivers who were active cigarette smokers and their linked asthmatic child (aged 2–12 years) were grouped into two classifications (“high” versus “low”) based on the child and caregiver’s cotinine levels. A “low” cotinine level was designated by at least a 25% reduction in cotinine levels during 3 months of the trial period; achieving ≤2 months of low cotinine levels defaulted to the “high” category. Twenty-seven dyads (caregivers and children) (total n = 54) were assigned to the “high” category, and eighteen dyads (caregivers and children) (total n = 36) were allocated to the “low” category. The primary outcome measure was the correlation of caregiver cotinine levels with pediatric cotinine values. Secondary outcomes included asthma control, in addition to caregiver anxiety and depression. (3) Results: Caregivers with 3 months of ≥25% decrease in cotinine levels had a significantly greater mean change in child cotinine levels (p = 0.018). “Low” caregiver cotinine levels did not significantly improve pediatric asthma control (OR 2.12 (95% CI: 0.62–7.25)). Caregiver anxiety and depression outcomes, measured by Patient Health Questionnaire (PHQ)-4 scores, was not significantly different based on cotinine categorization (p = 0.079); (4) Conclusion: Reduced pediatric cotinine levels were seen in caregivers who reduced their smoking for at least 3 months, but clinical outcome measures remained unchanged.

A randomized controlled trial protocol for engaging distress tolerance and working memory to aid smoking cessation in low socioeconomic status (SES) adults

Low income and low educational attainment are among the strongest predictors of both smoking prevalence and lapse (i.e., return) to smoking after cessation attempts. Treatment refinement is limited by inadequate knowledge of the specific lapse- or relapse-relevant vulnerabilities characteristic of populations that should be the target of treatment. In the context of a randomized clinical trial design, we describe an experimental medicine approach for evaluating the role of 2 specific lapse-relevant targets relative to the higher stress characteristic of low-socioeconomic contexts: low distress tolerance and low working memory capacity. Furthermore, we use an innovative approach for understanding risk of smoking lapse in smokers undergoing a quit attempt to examine candidate mechanistic targets assessed not only during nicotine use, but also during the conditions smokers will face upon a cessation attempt-during stressful nicotine-deprivation windows. This study is designed to show the incremental value of assessments during deprivation windows, in part because of the way in which specific vulnerabilities are modified by, and interact with, the heightened stress and withdrawal symptoms inherent to nicotine-deprivation states. Specifically, the study is designed to evaluate whether a novel mindfulness intervention (mindfulness combined with interoceptive exposure) can improve upon existing mindfulness interventions and extend therapeutic gains to the modification of mechanistic targets assessed in high-stress or negative affectivity contexts. The overall goal is to validate mechanistic targets and associated interventions for the purpose of expanding treatment options for at-risk smokers.

Cross-Sectional Study of Ethnicity and Chronic Heart Failure: Complex Interplay of Health and Wealth

Objectives: Extrapolating data from international and regional registries on chronic heart failure provides a challenge in Malaysia in view of it being a multicultural country. This study aimed to illustrate the chronic heart failure landscape within northern Kuala Lumpur and identify differences amongst major ethnic groups. Methods: A retrospective, single-centre study was conducted between the 1st January 2013 and 30th April 2016. Patients with left ventricular ejection fraction ≤45% were identified and information was collected on these individuals’ demographics, risk factors, and aetiology. Comparisons were made between three major ethnic groups within Malaysia, and between the author’s database and that of other international registries. Results: 1,181 patients were identified, the majority being Malays (67.3%) and male (81.2%). The mean age was 58.2±11.7 years. The majority had ischaemic risk factors, including previous and current smoking habits (56.7%), coronary artery disease (66.1%), hypertension (71.2%), diabetes (61.8%), and dyslipidaemia (47.9%). There were significant differences noted when looking at rates of dyslipidaemia, diabetes, atrial fibrillation, and chronic kidney disease amongst different ethnicities. The mean left ventricular ejection fraction in Malays was lower (33.1±9.6%) compared to that of Chinese (34.7±8.7%) and Indians (34.9±8.3%). There was marked differences seen in this study’s cohort, compared to three major Asian registries: The 2003 Chong et al. registry, Inter-CHF, and ASIAN-HF. Conclusion: There exists great disparity in chronic heart failure burden amongst populations, and therefore local registries are needed to narrow the gap in knowledge regarding chronic heart failure within Malaysia.

Smoking cessation and survival among people diagnosed with non-metastatic cancer

Background

We aimed to estimate the effects of smoking cessation on survival among people diagnosed with cancer.

Methods

We used data from a Comprehensive Community Cancer Program that is part of a large urban safety-net hospital system. Eligible patients were diagnosed with primary invasive solid tumors between 2013 and 2015, and were current smokers at time of diagnosis. Our exposure of interest was initiation of smoking cessation within 6 months of cancer diagnosis. We estimated inverse probability weighted restricted mean survival time (RMST) differences and risk ratio (RR) for all cause 3-year mortality.

Results

Our study population comprised 369 patients, of whom 42% were aged < 55 years, 59% were male, 44% were racial/ethnic minorities, and 59% were uninsured. The 3-year RMST was 1.8 (95% CL: − 1.5, 5.1) months longer for individuals who initiated smoking cessation within 6 months of cancer diagnosis. The point estimate for risk of 3-year mortality was lower for initiation of smoking cessation within 6 months of diagnosis compared with no initiation within 6 months (RR = 0.72, 95% CL: 0.37, 1.4).

Conclusions

Our point estimates suggest longer 3-year survival, but the results are compatible with 1.5 month shorter or 5.1 longer 3-year overall survival after smoking cessation within 6 months of cancer diagnosis. Future studies with larger sample sizes that test the comparative effectiveness of different smoking cessation strategies are needed for more detailed evidence to inform decision-making about the effect of smoking cessation on survival among cancer patients.

Implications for Cancer survivors

The benefits of smoking cessation after cancer diagnosis may include longer survival, but the magnitude of benefit is unclear.

Sociodemographic Correlates of Food Insecurity Among New York City Tobacco Users

PURPOSE

To identify rates and sociodemographic correlates of food insecurity among low-income smokers.

DESIGN

Cross-sectional analysis of baseline survey data from a randomized controlled trial (N = 403) testing a smoking cessation intervention for low-income smokers.

SETTING

Two safety-net hospitals in New York City.

SAMPLE

Current smokers with annual household income <200% of the federal poverty level.

MEASURES

Food insecurity was measured using the United States Department of Agriculture 6-item food security module. Participant sociodemographics were assessed by self-reported survey responses.

ANALYSIS

We used frequencies to calculate the proportion of smokers experiencing food insecurity and multivariable logistic regression to identify factors associated with being food insecure.

RESULTS

Fifty-eight percent of participants were food insecure, with 29% reporting very high food insecurity. Compared to married participants, separated, widowed, or divorced participants were more likely to be food insecure (adjusted odds ratio [AOR] = 2.33, 95% confidence interval [CI]: 1.25-4.33), as were never married participants (AOR = 2.81, 95% CI: 1.54-5.14).

CONCLUSIONS

Health promotion approaches that target multiple health risks (eg, smoking and food access) may be needed for low-income populations. Interventions which seek to alleviate food insecurity may benefit from targeting socially isolated smokers.

Knowledge, attitudes, harm perception, and practice related to waterpipe smoking in Lebanon

Waterpipe smoking (WPS) is one of the most emerging popular trends in Lebanon, with a prevalence of 36.9%, the highest among all Middle Eastern countries. Thus, the primary objective of the study was to examine the factors associated with knowledge, attitudes, and practice (KAP) related to WPS among a representative sample of waterpipe smokers. The secondary objective was to examine the effect of KAP on cumulative waterpipe dose and dependence. This cross-sectional study was carried out between May and December 2018 and enrolled a representative sample of 1550 waterpipe smokers from all Lebanese districts. The questionnaire used was specifically designed for this study. High knowledge score (Beta = 0.02, p = 0.002) were significantly associated with higher waterpipe harm perception score. In addition, high knowledge score (Beta = 0.32, p = 0.007) were significantly associated with higher attitude score toward smoking ban. Higher waterpipe harm perception score (Beta = - 1.30, p < 0.001), higher attitude (Beta = - 0.21, p < 0.001), and higher knowledge score (Beta = - 0.11, p < 0.001) were significantly associated with lower waterpipe dependence. In addition, higher waterpipe dependence (Beta = 2.02, p < 0.001) was significantly associated with higher cumulative waterpipe smoking, while higher waterpipe harm perception score (Beta = - 1.96, p = 0.009) and higher knowledge score (Beta = 0.27, p < 0.001) were significantly associated with lower cumulative waterpipe smoking. Our main finding was that better knowledge and perception of the harmful effects of waterpipe were related to a better attitude toward smoking bans and a lower waterpipe smoking. Therefore, health care providers and policymakers should join efforts to make awareness campaigns across Lebanon and develop adequate interventions to curb the use of waterpipe among the population.

Targeting cognitive and emotional regulatory skills for smoking prevention in low-SES youth: A randomized trial of mindfulness and working memory interventions

Research to date provides striking evidence that youth from low socio-economic status (SES) households are at an increased risk for smoking. Converging evidence from developmental studies, psychopathology studies, intervention studies, and basic research on self-control abilities have identified working memory and distress tolerance as potential crucial modifiable risk factors to prevent smoking onset in this cohort. To confirm the value of these mechanistic targets, this randomized trial was designed to evaluate the influence of working memory and distress tolerance interventions on risk of smoking initiation. Recruiting primarily from low-income community afternoon programs, we randomized 93 adolescents to one of three intervention conditions, all of which were a prelude to a smoking-prevention informational intervention: (1) a working memory intervention, (2) a mindfulness training intervention to target distress tolerance, and (3) a wellness-focused control condition. Despite a number of adherence efforts, engagement in treatment was limited, and under these conditions no significant evidence was found either for differential efficacy for smoking prevention or for intervention effects on mechanistic targets. However, working memory capacity and distress tolerance were found to be negatively related to smoking propensity. As such, our mechanistic targets-working memory and distress tolerance--may well be processes undergirding smoking, despite the fact that our interventions did not adequately engage these targets.

Association between snus use over time and smoking cessation in Norwegian smokers

BACKGROUND AND AIMS

The effect of snus (Swedish moist snuff) use over time on smoking cessation has not been clearly established. This study aimed to assess whether there is an association between snus use over the life-span and smoking cessation in Norway.

DESIGN AND SETTING

Yearly national cross-sectional surveys (2007-17) among Norwegian adults.

PARTICIPANTS

A total of 5353 ever-daily smokers aged 16-79 years, 61.0% of whom (n = 3268) had quit daily smoking, and 16.9% (n = 903) were ever snus users.

MEASUREMENTS

Retrospective data on smoking and snus use initiation and smoking cessation. Cox proportional hazard models were applied to estimate the association between time from initiation of snus use and quitting smoking.

FINDINGS

There was a significant association between snus use and quitting smoking during the 5 first years after starting using snus (hazard ratio = 1.92, confidence interval = 1.62-2.26), but not thereafter.

CONCLUSION

In Norway, snus use appears to be associated with a higher likelihood of quitting smoking within the first 5 years of initiation of this use.

The Affordable Care Act Medicaid Expansion and Smoking Cessation Among Low-Income Smokers

INTRODUCTION

This study sought to empirically evaluate whether the Medicaid expansion under the Affordable Care Act increased smoking cessation among low-income childless adult smokers.

METHODS

The effects of the Medicaid expansion on smoking quit attempts and the probability of 30- and 90-day smoking cessation were evaluated using logistic regression and data from the 2010-2011 and 2014-2015 waves of the Tobacco Use Supplement to the Current Population Survey. Using boosted logistic regression, the Tobacco Use Supplement was restricted to an analytic sample composed of childless adults with high probability of being <138% of the federal poverty level. Propensity score weighting was used to compare changes in smoking cessation among a sample of current and past smokers in states that expanded Medicaid with a control sample of current and past smokers in states that did not expand Medicaid with similar sociodemographic characteristics and smoking histories. This study additionally controlled for state socioeconomic trends, welfare policies, and tobacco control policies. Analysis was conducted between January 2018 and June 2019.

RESULTS

After weighting by propensity score and adjusting for state socioeconomic trends, welfare policies, and tobacco control policies, the Medicaid expansion was not associated with increases in smoking quit attempts or smoking cessation.

CONCLUSIONS

The Medicaid expansion did not appear to improve smoking cessation, despite extending health insurance eligibility to 2.3 million low-income smokers. Greater commitments to reducing barriers to cessation benefits and increasing smoking cessation in state Medicaid programs are needed to reduce smoking in low-income populations.

Differential Relationship between Tobacco Control Policies and U.S. Adult Current Smoking by Poverty

The study's purpose was to identify differences in the relationship between tobacco control policies and smoking by poverty. We matched state smoke-free air law coverage (SFALs), tobacco control funding (TCF), and cigarette taxes with individual current smoking and demographics from supplements to the Current Population Survey (1985-2015). We regressed (logistic) smoking on policy variables, poverty (<138% of poverty line versus ≥138% of poverty line), interactions of policy and poverty, and covariates, presenting beta coefficients instead of odds ratios because it is difficult to interpret interactions using odds ratios (they are ratios of odds ratios). We coded SFALs as (1) proportion of state covered by 100% workplace, restaurant and bar laws (SFAL-All) or (2) proportion of state covered by workplace laws (SFAL-WP) and proportion covered by restaurant or bar laws (SFAL-RB). In the SFAL-All model, SFAL-All (Beta coeff: -0.03, 95% CI: -0.06, -0.002), tax (Coeff: -0.06, 95% CI: -0.07, -0.05), and TCF (Coeff: -0.01, 95% CI: -0.01, -0.001) were associated with less smoking. In this model, the interaction of SFAL-All by poverty was significant (Coeff: 0.08, 95% CI: 0.02, 0.13). In the SFAL-WP/RB model, SFAL-RB (Coeff: -0.05, 95% CI: -0.08, -0.02), tax (Coeff: -0.05, 95% CI: -0.06, -0.04), and TCF (Coeff: -0.01, 95% CI: -0.01, -0.00) were significant. In the same model, SFAL-WP (Coeff: 0.09, 95% CI: 0.03, 0.15), SFAL-RB (Coeff: -0.14, 95% CI: -0.19, -0.09), and TCF (Coeff: 0.01, 95% CI: 0.00, 0.02) interacted with poverty. Tax by poverty was of borderline significance in this model (Coeff = 0.02, 95% CI: -0.00, 0.04, p = 0.050). Among adults, SFALs, TCF, and tax were associated with less current smoking, and SFALs and TCF had differential relationships with smoking by poverty.

Comparing in person and internet methods to recruit low-SES populations for tobacco control policy research

Tobacco use and the associated consequences are much more prevalent among low-SES populations in the U.S. However, tobacco-based research often does not include these harder-to-reach populations. This paper compares the effectiveness and drawbacks of three methods of recruiting low-SES adult smokers in the Northeast. From a 5-year, [funding blinded] grant about impacts of graphic warning labels on tobacco products, three separate means of recruiting low-SES adult smokers emerged: 1) in person in the field with a mobile lab vehicle, 2) in person in the field with tablet computers, and 3) online via Amazon Mechanical Turk (MTurk). We compared each of these methods in terms of the resulting participant demographics and the "pros" and "cons" of each approach including quality control, logistics, cost, and engagement. Field-based methods (with a mobile lab or in person with a tablet) yielded a greater proportion of disadvantaged participants who could be biochemically verified as current smokers-45% of the field-based sample had an annual income of <$10,000 compared to 16% of the MTurk sample; 40-45% of the field-based sample did not complete high school compared to 2.6% of the MTurk sample. MTurk-based recruitment was substantially less expensive to operate (1/14th the cost of field-based methods) was faster, and involved less logistical coordination, though was unable to provide immediate biochemical verification of current smoking status. Both MTurk and field-based methods provide access to low-SES participants-the difference is the proportion and the degree of disadvantage. For research and interventions where either inclusion considerations or external validity with low-SES populations is critical, especially the most disadvantaged, our research supports the use of field-based methods. It also highlights the importance of adequate funding and time to enable the recruitment and participation of these harder-to-reach populations.

Relationships between smoking duration, smoking intensity, hypothetical tobacco price increases, and smoking habit change intention among current smokers in Shanghai

Objectives

We conducted a cross-sectional study to explore the effect of a hypothetical tobacco retail price increase on smoking habit change intention, and the role of smoking duration and intensity in smoking change intention.

Methods

In 2016 and 2017, we collected questionnaire data from 36,698 residents aged over 18 years in Songjiang district, Shanghai. Chi-square tests and weighted logistic regression were used for data analyses.

Results

The prevalence of current smoking was 19.78% (men: 48.36% and women: 0.22%). A total of 10.83% (men: 10.89% and women: 2.04%) and 9.39% of smokers (men: 9.42% and women: 6.12%) expressed the intention to smoke less or quit, respectively, given tobacco retail price increases. If the current tobacco retail price doubled, 75% of smokers stated that they would smoke less and 60% of smokers would consider quitting. Smokers with longer smoking duration and lower smoking intensity were more sensitive to tobacco price increases and more likely to change their smoking habits.

Conclusions

An increase in tobacco retail prices could induce some smokers to change their smoking behavior, particularly those with longer smoking duration and lower smoking intensity. A tobacco retail price increase is recommended, which should apply to all cigarette brands.

Receipt of direct tobacco mail/email coupons and coupon redemption: Demographic and socioeconomic disparities among adult smokers in the United States

A key marketing strategy used by tobacco companies to lower tobacco product prices is the distribution of tobacco coupons via direct marketing channels such as mail or email. We analyzed data on adult smokers from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study (n = 10,994) to examine the prevalence and correlates of coupon receipt via both channels, and associations with cigarette coupon redemption. Overall, 22% and 32% of smokers received tobacco coupons via email and mail, respectively, and 22% redeemed cigarette coupons. White, 25-44 year old, female, sexual minority, and more nicotine dependent smokers were more likely to receive coupons via both channels and to redeem coupons, as were smokers with mid-levels education (GED to associate degree) and those unable to pay important bills (OR _{email receipt} = 1.37, 95% CI 1.22-1.54; OR _{mail receipt} = 1.38, 95% CI 1.24-1.55; and OR _{coupon redemption} = 1.44, 95% CI 1.26-1.64). Smokers who received coupons via mail only or via both channels, had three times (OR = 2.97, 95% CI 2.31-3.83) and five times (OR = 4.56, 95% CI 3.61-5.76) higher odds to redeem cigarette coupons compared to those who received them via email only. Major demographic and socioeconomic disparities exist in receipt and redemption of direct email\mail tobacco coupons among US smokers. Cigarette coupons received via direct mail are more likely to be redeemed than coupons received via email. Restrictions on tobacco coupon redemption, implemented jointly with increasing access to affordable cessation resources, may incentivize smokers vulnerable to tobacco marketing tactics to quit.

Racial/Ethnic Differences in Duration of Smoking Among Former Smokers in the National Health and Nutrition Examination Surveys

Introduction

The burden of tobacco-related disease is not uniformly distributed across racial/ethnic groups. Differences in smoking duration by race/ethnicity may contribute to this disparity. Previous studies have examined racial/ethnic differences in smoking duration among ever smokers (former and current smokers combined). It is unknown if racial/ethnic differences in smoking duration are evident among quitters. This study examined racial/ethnic differences in duration of smoking among former smokers in the United States.

Methods

We studied 6030 white, black, and Mexican-American former smokers (3647 men and 2383 women) aged 20-79 years who participated in the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2012. Mean differences in smoking duration by race/ethnicity were estimated using linear regression models.

Results

After adjustment for demographics, age at smoking initiation and smoking intensity, compared to white men, black men smoked for 2.3 (95% confidence interval [CI]: 1.3, 3.3) years longer before quitting and Mexican-American men for 0.2 (95% CI: -1.6, 1.2) years less before quitting. Compared to white women, black women smoked for 1.9 (95% CI: 0.7, 3.0) years longer before quitting and Mexican-American women for 0.9 (95% CI: -2.4, 0.5) years less before quitting.

Conclusions

In a representative sample of US adults, black former smokers continued smoking for longer periods before quitting compared to white former smokers. These findings support the need for smoking cessation efforts that address racial/ethnic differences in smoking behaviors. The longer time to quit among black former smokers should be investigated as an explanation for racial/ethnic disparities in smoking-associated diseases.

Implications

In a representative sample of US adults that successfully quit smoking, the timing of smoking cessation differed by race/ethnicity with blacks smoking for longer periods before quitting compared to whites. Racial/ethnic differences in duration of smoking among former smokers differed by participant age and age at smoking initiation. These findings support the need for smoking cessation efforts that address racial/ethnic differences in smoking behaviors.

Socioeconomic differences in nicotine exposure and dependence in adult daily smokers

Background

Socioeconomic status (SES) is a major determinant of tobacco use but little is known whether SES affects nicotine exposure and the degree of nicotine dependence.

Methods

The Pennsylvania Adult Smoking Study is a cross-sectional study of smoke exposure and nicotine dependence among adults conducted in central Pennsylvania between June 2012 and April 2014. The study included several measures of SES, including assessments of education and household income, as well as occupation, home ownership, health insurance, household density and savings accounts. Measurements included saliva for the nicotine metabolites cotinine (COT), 3-‘hydroxycotinine (3HC) and total metabolites (COT +3HC). Puffing behavior was determined using portable smoking topography devices.

Results

The income levels of lighter smokers (< 20 cigarettes per day) was $10,000 more than heavier smokers. Higher Fagerström Test for Nicotine Dependence scores were associated with lower income and job status, scores ranged from 5.4 in unemployed, 4.4 in blue-collar, and 3.8 in white-collar workers. In principal components analysis used to derive SES indicators, household income, number in household, and type of dwelling were the major SES correlates of the primary component. Job category was the major correlate of the second component. Lower SES predicted significantly higher adjusted total nicotine metabolite levels in the unemployed group. Job category was significantly associated with total daily puffs, with the highest level in the unemployed, followed by blue-collar workers, after adjustment for income.

Conclusions

Among smokers, there was a relationship between lower SES and increased nicotine dependence, cigarettes per day and nicotine exposure, which varied by job type.

Conscientiousness explains the link between childhood neglect and cigarette smoking in adults from a low-income, urban area-the differential effects of sex

Cigarette smoking represents the leading cause of preventable morbidity and mortality in the US and understanding its risk factors remains a critical public health endeavor. Low-income individuals and individuals with a history of childhood maltreatment are at heightened risk for cigarette smoking, yet the underlying factors between this association are understudied. Conscientiousness is one construct with potential explanatory relevance to both smoking and childhood neglect. The current investigation examined the association between childhood physical and emotional neglect with smoking (i.e., self-reported cigarette smoking and breath carbon monoxide levels) via conscientiousness. The sample was comprised of 115 adults (M_age = 50.46, SD_age = 5.86; 76.4% Black) recruited from a community center serving low-income and homeless individuals. Mediation analyses showed the indirect effect of childhood emotional neglect on cigarette smoking through conscientiousness; for physical neglect, this relationship was only present among males. The current study provides preliminary evidence that conscientiousness may be a particularly important vulnerability factor when examining the association between childhood neglect and smoking.

Tobacco use among non-elderly adults with and without criminal justice involvement in the past year: United States, 2008-2016

BACKGROUND

Tobacco use remains the leading cause of preventable disease and death in the United States and is concentrated among disadvantaged populations, including individuals with a history of criminal justice involvement. However, tobacco use among individuals with a history of criminal justice involvement has been understudied in the United States, and data are needed to inform policy and practice.

METHODS

We used data from the 2008-2016 National Survey on Drug Use and Health (unweighted N = 330,130) to examine trends in tobacco use, categories of tobacco use, characteristics of cigarette use, and health care utilization and tobacco use screening among individuals (aged 18-64) with and without a history of criminal justice involvement in the past year. We used multiple logistic and Poisson regression models with predictive margins to provide adjusted prevalence estimates.

RESULTS

The weighted sample in each year was, on average, representative of 8,693,171 individuals with a history of criminal justice involvement in the past year and 182,817,228 individuals with no history of criminal justice involvement in the past year. Tobacco use was significantly more common among individuals with a history of criminal justice involvement compared with individuals with no criminal justice involvement, and disparities increased over time (Difference in adjusted relative differences: - 10.2% [95% CI - 17.7 to - 2.7]). In 2016, tobacco use prevalence was more than two times higher among individuals with a history of criminal justice involvement (62.9% [95% CI 59.9-66.0] vs. 27.6% [95% CI 26.9-28.3]). Individuals with a history of criminal justice involvement who smoked reported a significantly earlier age of cigarette initiation, more cigarettes used per day, and higher levels of nicotine dependence and chronic obstructive pulmonary disease. Individuals with a history of criminal justice involvement were less likely to report an outpatient medical visit in the past year and, among those reporting an outpatient medical visit, were less likely to be asked about tobacco use, but paradoxically, more likely to report being advised to quit.

CONCLUSIONS

Novel programs and tobacco control policies are needed to address persistently high rates of tobacco use and reduce cardiovascular morbidity and mortality among individuals with a history of criminal justice involvement.

A review of the effects of nicotine on social functioning

Many smokers are aware that smoking is a dangerous health behavior and eventually try to quit smoking. Unfortunately, most quit attempts end in failure. Traditionally, the addictive nature of smoking has been attributed to the pharmacologic effects of nicotine. In an effort to offer a more comprehensive, biobehavioral analysis of smoking behavior and motivation, some researchers have begun to consider the role of social factors in smoking. In line with recent recommendations to integrate social and pharmacological analyses of smoking, we reviewed the experimental literature examining the effects of nicotine and nicotine withdrawal on social functioning. The review identified 13 studies that experimentally manipulated nicotine and assessed social functioning, 12 of which found support for nicotine's enhancement of social functioning. Although few experiments have investigated social functioning, they nevertheless offer compelling evidence that nicotine enhances social functioning in smokers and suggest that nicotine deprivation may hamper social functioning in those dependent on nicotine. Future directions for investigating social outcomes and context in those who use nicotine products are discussed with a focus on leveraging advances in social and developmental psychology, animal research, sociology, and neuroimaging to more comprehensively understand smoking behavior.

Educational Attainment and Smoking Status in a National Sample of American Adults; Evidence for the Blacks' Diminished Return

BACKGROUND

Although higher socioeconomic status (SES) indicators such as educational attainment are linked with health behaviors, the Blacks’ Diminished Return theory posits that the protective effects of SES are systemically smaller for Blacks than Whites.

AIMS

To explore the Black/White differences in the association between education and smoking.

METHODS

This cross-sectional study used the Health Information National Trends Survey (HINTS) 2017 (n = 3217). HINTS is a national survey of American adults. The current analysis included 2277 adults who were either Whites (n = 1868; 82%) or Blacks (n = 409; 18%). The independent variable was educational attainment, and the dependent variables were ever and current (past 30-day) smoking. Demographic factors (age and gender) were covariates. Race was the focal moderator.

RESULTS

In the pooled sample, higher educational attainment was associated with lower odds of ever and current smoking. Race interacted with the effects of higher educational attainment on current smoking, suggesting a stronger protective effect of higher education against current smoking for Whites than Blacks. Race did not interact with the effect of educational attainment on odds of ever smoking.

CONCLUSIONS

In line with previous research in the United States, education is more strongly associated with health and health behaviors in Whites than Blacks. Smaller protective effects of education on health behaviors may be due to the existing racism across institutions such as the education system and labor market.

What factors are associated with abstinence amongst socioeconomically disadvantaged smokers? A cross-sectional survey of use of cessation aids and quitting approach

INTRODUCTION AND AIMS

This study aimed to compare current and ex-smokers' sociodemographic and psychosocial characteristics, use of cessation aids and abrupt versus gradual quitting approaches.

DESIGN AND METHODS

A cross-sectional survey of financially disadvantaged adults attending a community service organisation was conducted in New South Wales, Australia, between February 2012 and December 2013. Sociodemographic and psychosocial factors, use of cessation aids and gradual versus abrupt quit approach were assessed. χ2 tests and logistic regression compared characteristics of current and ex-smokers.

RESULTS

Of 905 individuals who completed the survey, 639 (71%) were current smokers and 107 (12%) were ex-smokers. Ex-smokers were older [odds ratio (OR) = 1.03, 95% confidence interval (CI) = 1.01, 1.05], had higher odds of being female (OR = 1.67, 95% CI = 1.06, 2.65), lower odds of being financially stressed (OR = 0.87, 95% CI = 0.76, 0.99), lower odds of anxiety and depression symptoms (OR = 0.91, 95% CI = 0.84, 0.98) and lower odds of having friends and family who were smokers (ORs ranged from 0.30-0.43). Ex-smokers had lower odds of using cessation aids and higher odds of reporting abrupt quitting during their last quit attempt (OR = 4.48, 95% CI = 2.66, 7.54).

CONCLUSIONS

Lower levels of disadvantage, less smoking in social networks, less use of cessation aids and abrupt (vs. gradual) quitting approaches were associated with being an ex-smoker. Lower use of evidence based methods to quit by disadvantaged ex-smokers requires further exploration. [Twyman L, Bonevski B, Paul C, Bryant J, West R, Siahpush M, D'este C, Oldmeadow C, Palazzi K.

Income Disparities in the Prevalence, Severity, and Costs of Co-occurring Chronic and Behavioral Health Conditions

BACKGROUND

Behavioral health problems usually co-occur along with physical health problems, resulting in higher health care costs. These co-occurring conditions are likely to be more prevalent and serious among low income patients, affecting both the quality and costs of care.

OBJECTIVE

To examine the prevalence, severity, and health care costs of co-occurring chronic and behavioral health conditions among low income people compared with higher income people.

METHODS

Analysis of the 2011-2014 Medical Expenditure Panel Survey. Sample includes 146,000 persons aged 18-64 years. Regression analysis was used to examine how the combination of behavioral health conditions and chronic health conditions is associated with health care expenditures, and how this association differs by family income.

RESULTS

(1) Comorbid behavioral health problems are more prevalent and serious among low income people with chronic conditions compared with higher income people; (2) among patients with co-occurring chronic and behavioral problems, average annual spending is greater among the low income patients ($9472) compared with high income patients ($7457); (3) higher costs among low income patients with co-occurring conditions reflects their poorer mental and physical health, relative to higher income patients.

CONCLUSIONS

For many low income people, comorbid behavioral problems need to be understood in the social context in which they live. Simply screening low income people for behavioral health problems may not be sufficient unless there is greater understanding of the mechanisms that both cause and exacerbate chronic and behavioral health problems in the low income population.

Effect of UGT2B10, UGT2B17, FMO3, and OCT2 genetic variation on nicotine and cotinine pharmacokinetics and smoking in African Americans

OBJECTIVES

Nicotine metabolism rates differ considerably among individuals, even after controlling for variation in the major nicotine-metabolizing enzyme, CYP2A6. In this study, the impact of genetic variation in alternative metabolic enzymes and transporters on nicotine and cotinine (COT) pharmacokinetics and smoking was investigated.

METHODS

We examined the impact of UGT2B10, UGT2B17, FMO3, NAT1, and OCT2 variation on pharmacokinetics and smoking (total nicotine equivalents and topography) before and after stratifying by CYP2A6 genotype in 60 African American (AA) smokers who received a simultaneous intravenous infusion of deuterium-labeled nicotine and COT.

RESULTS

Variants in UGT2B10 and UGT2B17 were associated with urinary glucuronidation ratios (glucuronide/free substrate). UGT2B10 rs116294140 was associated with significant alterations in COT and modest alterations in nicotine pharmacokinetics. These alterations, however, were not sufficient to change nicotine intake or topography. Neither UGT2B10 rs61750900, UGT2B17*2, FMO3 rs2266782, nor NAT1 rs13253389 altered nicotine or COT pharmacokinetics among all individuals (n=60) or among individuals with reduced CYP2A6 activity (n=23). The organic cation transporter OCT2 rs316019 significantly increased nicotine and COT Cmax (P=0.005, 0.02, respectively) and decreased nicotine clearance (P=0.05). UGT2B10 rs116294140 had no significant impact on the plasma or urinary trans-3'-hydroxycotinine/COT ratio, commonly used as a biomarker of CYP2A6 activity.

CONCLUSION

We found that polymorphisms in genes other than CYP2A6 represent minor sources of variation in nicotine pharmacokinetics, insufficient to alter smoking in AAs. The change in COT pharmacokinetics with UGT2B10 rs116294140 highlights the UGT2B10 gene as a source of variability in COT as a biomarker of tobacco exposure among AA smokers.

Lung cancer incidence trends in California by race/ethnicity, histology, sex, and neighborhood socioeconomic status: An analysis spanning 28 years

OBJECTIVES

Lung cancer incidence trends by histology, sex, race/ethnicity, and neighborhood socioeconomic status (nSES) have not been previously reported. We conducted a population-based study of lung cancer incidence over three peri-censal periods: 1988-1992, 1998-2002, and 2008-2012.

MATERIALS AND METHODS

We abstracted lung cancer cases from the California Cancer Registry and used US Census and American Community Survey data to develop multidimensional nSES indices for each census period. We calculated nSES tertile-specific incidence rates and rate ratios for each peri-censal period and used incidence rate ratios (IRR) to assess changes in rates from 1988 to 1992 to 1998-2002 and 2008-2012.

RESULTS

There were a total of 231,205 lung cancer cases. Males: Among males, incidence rates of lung cancer decreased over time, all race/ethnicities, and all nSES tertiles, with larger declines among males in higher nSES areas. Rates either declined or were stable for adenocarcinoma, with larger declines for other histologic subtypes. Females: Among females, declines in incidence rates of lung cancer were more pronounced for females in higher nSES areas, but diverged more so than for males, with variations by histology and race/ethnicity. Incidence rates of adenocarcinoma increased over time among all females, with greater increase among females in low nSES areas.

CONCLUSIONS

Our findings demonstrate differences in incidence trends over three decades by histology, gender, race/ethnicity, and nSES. While incidence rates consistently declined over time for males, there were greater declines in incidence for high nSES populations. In contrast, among females, there was evidence of increases in lung cancer incidence among low SES API females, and for adenocarcinoma.

Disposition kinetics and metabolism of nicotine and cotinine in African American smokers: impact of CYP2A6 genetic variation and enzymatic activity

OBJECTIVE

The rate of nicotine metabolism, determined primarily by CYP2A6 activity, influences tobacco dependence and smoking-induced disease risk. The prevalence of CYP2A6 gene variants differs by race, with greater numbers in African Americans compared with Caucasians. We studied nicotine disposition kinetics and metabolism by the CYP2A6 genotype and enzymatic activity, as measured by the nicotine metabolite ratio (NMR), in African American smokers.

METHODS

Participants were administered intravenous infusions of deuterium-labeled nicotine and cotinine. Plasma and urine concentrations of nicotine and metabolites were measured and pharmacokinetic parameters were estimated.

RESULTS

Pharmacokinetic parameters and urine metabolite excretion data were analyzed by CYP2A6 genotype and by NMR. A number of gene variants were associated with markedly reduced nicotine and cotinine clearances. NMR was strongly correlated with nicotine (r=0.72) and cotinine (r=0.80) clearances. Participants with higher NMR excreted significantly greater nicotine C-oxidation and lower non-C-oxidation products compared with lower NMR participants.

CONCLUSION

CYP2A6 genotype, NMR, and nicotine pharmacokinetic data may inform studies of individual differences in smoking behavior and biomarkers of nicotine exposure.

Intergenerational differences in smoking among West Indian, Haitian, Latin American, and African blacks in the United States

Due in large part to increased migration from Africa and the Caribbean, black immigrants and their descendants are drastically changing the contours of health disparities among blacks in the United States. While prior studies have examined health variation among black immigrants by region of birth, few have explored the degree of variation in health behaviors, particularly smoking patterns, among first- and second- generation black immigrants by ancestral heritage. Using data from the 1995-2011 waves of the Tobacco Use Supplements of the Current Population Survey (TUS-CPS), we examine variation in current smoking status among first-, second-, and third/higher- generation black immigrants. Specifically, we investigate these differences among all black immigrants and then provide separate analyses for individuals with ancestry from the English-speaking Caribbean (West Indies), Haiti, Latin America, and Africa-the primary sending regions of black immigrants to the United States. We also explore differences in smoking behavior by gender. The results show that, relative to third/higher generation blacks, first-generation black immigrants are less likely to report being current smokers. Within the first-generation, immigrants who migrated after age 13 have a lower probability of smoking relative to those who migrated at or under age 13. Disparities in smoking prevalence among the first-generation by age at migration are largest among black immigrants from Latin America. The results also suggest that second-generation immigrants with two foreign-born parents are generally less likely to smoke than the third/higher generation. We find no statistically significant difference in smoking between second-generation immigrants with mixed nativity parents and the third or higher generation. Among individuals with West Indian, Haitian, Latin American, and African ancestry, the probability of being a current smoker increases with each successive generation. The intergenerational increase in smoking, however, is slower among individuals with African ancestry. Finally, with few exceptions, our results suggest that intergenerational gaps in smoking behavior are larger among women compared to men. As additional sources of data for this population become available, researchers should investigate which ancestral subgroups are driving the favorable smoking patterns for the African origin population.

An Empirical Analysis of the Association Between Cigarette Smoking and Participation in the Supplemental Nutrition Assistance Program

PURPOSE

To examine the association between smoking and participation in Supplemental Nutrition Assistance Program (SNAP) among low-income families.

DESIGN

A quasi-experimental design using pooled cross-sectional data from the Bureau of Labor Statistics' Consumer Expenditure Diary Survey.

SETTING

A national, representative sample of US households from 2005 through 2012.

PARTICIPANTS

A total of 19 395 low-income households.

MEASURES

US poverty thresholds were used, in conjunction with household income, to create a sample of families at 130% of the federal poverty level and below. Expenditures on cigarettes and self-reported enrollment in SNAP were used to measure smoking behavior and program participation, respectively.

ANALYSIS

Estimation of a maximum likelihood model was used to predict the probability of smoking given participation in SNAP.

RESULTS

The SNAP participation among low-income households was associated with a 30% ( P < .01) increase in the likelihood of a household containing at least 1 smoker, relative to low-income non-SNAP households. Among smokers, SNAP households do not spend more money on tobacco products than non-SNAP households.

CONCLUSION

Given the strong association found between SNAP participation and smoking, connecting program participants who smoke to effective smoking cessation programs could be an effective tool in reducing the prevalence of smoking among the low-income population. States have a unique opportunity to use SNAP-Education programs to integrate tobacco prevention and cessation into curriculum for direct client impact.

Tobacco policies and on-premise smoking in bars and clubs that cater to young African Americans following the Maryland Clean Indoor Air Act of 2007

African American young adults ages 18-25 smoke less than their Caucasian peers, yet the burden of tobacco-related illness is significantly higher in African Americans than in Caucasians across the lifespan. Little is known about how clean indoor air laws affect tobacco smoking among African American young adults. We conducted a systematic observation of bars and clubs with events targeted to African American adults 18-25 in Baltimore City at two timepoints (October and November of 2008 and 2010) after enforcement of the Maryland Clean Indoor Air Act (CIAA). Twenty venues-selected on the basis of youth reports of popular venues-were rated during peak hours. All surveillance checklist items were restricted to what was observable in the public domain. There was a significant decrease in observed indoor smoking after CIAA enforcement. Observed outdoor smoking also decreased, but this change was not significant. Facilities for smoking outdoors increased significantly. The statewide smoking ban became effective February 1, 2008, yet measurable changes in smoking behavior in bars were not evident until the City engaged in stringent enforcement of the ban several months later.

Unnecessary Antibiotics for Acute Respiratory Tract Infections: Association With Care Setting and Patient Demographics

Background.  Up to 40% of antibiotics are prescribed unnecessarily for acute respiratory tract infections (ARTIs). We sought to define factors associated with antibiotic overprescribing of ARTIs to inform efforts to improve practice. Methods.  We conducted a retrospective analysis of ARTI visits between 2006 and 2010 from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. Those surveys provide a representative sample of US visits to community-based physicians and to hospital-based emergency departments (EDs) and outpatient practices. Patient factors (age, sex, race, underlying lung disease, tobacco use, insurance), physician specialty, practice demographics (percentage poverty, median household income, percentage with a Bachelor's Degree, urban-rural status, geographic region), and care setting (ED, hospital, or community-based practice) were evaluated as predictors of antibiotic overprescribing for ARTIs. Results.  Hospital and community-practice visits had more antibiotic overprescribing than ED visits (odds ratio [OR] = 1.64 and 95% confidence interval [CI], 1.27-2.12 and OR = 1.59 and 95% CI, 1.26-2.01, respectively). Care setting had significant interactions with geographic region and urban and rural location. The quartile with the lowest percentage of college-educated residents had significantly greater overprescribing (adjusted OR = 1.41; 95% CI, 1.07-1.86) than the highest quartile. Current tobacco users were overprescribed more often than nonsmokers (OR = 1.71; 95% CI, 1.38-2.12). Patient age, insurance, and provider specialty were other significant predictors. Conclusions.  Tobacco use and a lower grouped rate of college education were associated with overprescribing and may reflect poor health literacy. A focus on educating the patient may be an effective approach to stewardship.

Exploring why Costa Rica outperforms the United States in life expectancy: A tale of two inequality gradients

Mortality in the United States is 18% higher than in Costa Rica among adult men and 10% higher among middle-aged women, despite the several times higher income and health expenditures of the United States. This comparison simultaneously shows the potential for substantially lowering mortality in other middle-income countries and highlights the United States' poor health performance. The United States' underperformance is strongly linked to its much steeper socioeconomic (SES) gradients in health. Although the highest SES quartile in the United States has better mortality than the highest quartile in Costa Rica, US mortality in its lowest quartile is markedly worse than in Costa Rica's lowest quartile, providing powerful evidence that the US health inequality patterns are not inevitable. High SES-mortality gradients in the United States are apparent in all broad cause-of-death groups, but Costa Rica's overall mortality advantage can be explained largely by two causes of death: lung cancer and heart disease. Lung cancer mortality in the United States is four times higher among men and six times higher among women compared with Costa Rica. Mortality by heart disease is 54% and 12% higher in the United States than in Costa Rica for men and women, respectively. SES gradients for heart disease and diabetes mortality are also much steeper in the United States. These patterns may be partly explained by much steeper SES gradients in the United States compared with Costa Rica for behavioral and medical risk factors such as smoking, obesity, lack of health insurance, and uncontrolled dysglycemia and hypertension.

Latino Cigarette Smoking Patterns by Gender in a US-National Sample

BACKGROUND

Latino smokers are a rising public health concern who experience elevated tobacco-related health disparities.

PURPOSE

Additional information on Latino smoking is needed to inform screening and treatment.

ANALYSIS

Latent class analysis using smoking frequency, cigarette preferences, onset, smoking duration, cigarettes per day, and minutes to first cigarette was used to create multivariate latent smoking profiles for Latino men and women.

RESULTS

Final models found seven classes for Latinas and nine classes for Latinos. Despite a common finding in the literature that Latino smokers are more likely to be low-risk intermittent smokers, the majority of classes for both males and females described patterns of high-risk daily smoking. Gender variations in smoking classes were noted.

CONCLUSIONS

Several markers of smoking risk were identified among both male and female Latino smokers, including long durations of smoking, daily smoking, and preference for specialty cigarettes, all factors associated with long-term health consequences.

Racial Differences in Outcomes within the National Lung Screening Trial. Implications for Widespread Implementation

RATIONALE

Black individuals with lung cancer (LC) experience higher mortality because they present with more advanced disease and are less likely to undergo curative resection for early-stage disease. The National Lung Screening Trial (NLST) demonstrated improved LC mortality by screening high-risk patients with low-dose computed tomography (LDCT). The benefit of LDCT screening in black individuals is unknown.

OBJECTIVES

Examine results of the NLST by race.

METHODS

This was a secondary analysis of a randomized trial (NCT00047385) performed in 33 U.S. centers.

MEASUREMENTS AND MAIN RESULTS

Overall and lung cancer-specific mortality were measured. Screening with LDCT reduced LC mortality in all racial groups but more so in black individuals (hazard ratio [HR], 0.61 vs. 0.86). Smoking increased the likelihood of death from LC, and when stratified by race black smokers were twice as likely to die as white smokers (HR, 4.10 vs. 2.25). Adjusting for sociodemographic and behavioral characteristics, black individuals experienced higher all-cause mortality than white individuals (HR, 1.35; 95% confidence interval, 1.22-1.49); however, black individuals screened with LDCT had a reduction in all-cause mortality. Black individuals were younger, were more likely to be current smokers, had more comorbidities, and had fewer years of formal education than white individuals (P < 0.05).

CONCLUSIONS

Black individuals screened with LDCT had decreased mortality from lung cancer. However, the demographics associated with improved LC survival were less commonly found in black individuals. The overall mortality in the NLST was higher for black individuals than white individuals, but improved in black individuals screened, suggesting that this subgroup may have had improved access to care. To realize the reductions in mortality from LC screening, dissemination efforts need to be tailored to meet the needs of this community.
