A Population-Level Assessment of Smoking Cessation following a Diagnosis of Tobacco- or Nontobacco-Related Cancer among United States Adults

Motivating smoking cessation among patients with cancers not perceived as smoking-related: a targeted intervention

PURPOSE

Smoking after cancer impairs cancer treatment outcomes and prognosis, regardless of cancer type. Prior data suggest that patients with cancers other than lung or head/neck cancer had lower cessation motivation, which in turn predicted lower smoking abstinence. This study evaluated feasibility for a future efficacy trial and assessed the acceptability of brief self-help materials, targeted by cancer type, to enhance cessation motivation.

METHODS

Patients had a diagnosis of skin melanoma, breast, bladder, colorectal, or gynecological cancers within ≤ 6 months, smoked ≥ 1 cigarette in the past month, and were not currently participating in a cessation program. After completing a baseline assessment, participants received the booklet corresponding to their cancer type. Follow-ups were conducted 1 week and 1 month post-intervention.

RESULTS

Among 118 patients potentially eligible, 109 were successfully contacted and 53 patients were eligible and all consented. Among consenting patients, 92.5% completed baseline, and 90.6% received the intervention. Among patients receiving the intervention, 91.7% completed all study procedures and follow-up. At 1 month, 87.5% reported reading the booklet and 92.8% rated it as good/excellent. Motivation to quit smoking increased over time among those with lower motivation at baseline, 33.3% sought smoking cessation assistance, and 25.0% were smoke-free 1 month post-intervention.

CONCLUSION

This study demonstrated the feasibility and acceptability of the first intervention developed for patients with cancers not typically associated with smoking. This low-cost and easy to disseminate intervention has potential to increase motivation to quit smoking among patients with cancers not typically perceived as smoking-related.

Association between a diagnosis of diabetes mellitus and smoking abstinence: An analysis of the National Health Interview Survey (2006-2018)

OBJECTIVE

Both diabetes and smoking significantly increase the risk of cardiovascular disease (CVD). Understanding whether a diagnosis of diabetes can be leveraged to promote smoking cessation is a gap in the literature.

METHODS

We used data from the US National Health Interview Survey, 2006 to 2018, to investigate the relationship between self-report of diagnosis of diabetes and subsequent smoking abstinence among 142,884 respondents who reported regular smoking at baseline. Effect sizes were presented as hazard ratios (HRs) derived from multivariable Cox regression models adjusted for potential confounders using diabetes as a time-dependent covariate. Subgroup-specific estimates were obtained using interaction terms between diabetes and variables of interest.

RESULTS

A self-reported diagnosis of diabetes was associated with smoking abstinence (HR: 1.21; 95% CI: 1.16 to 1.27). The strength of the association varied based on race (P for interaction: 0.004), where it was strongest in African Americans (HR: 1.44; 95% CI: 1.29 to 1.60); income (P for interaction <0.001), where it was strongest in those with a yearly income less than $35,000 (HR: 1.45; 95% CI: 1.36 to 1.53); and educational attainment (P for interaction <0.001), where it was strongest in those who did not attend college (HR: 1.48; 95% CI: 1.40 to 1.57).

CONCLUSION

Among adults who smoke, a diagnosis of diabetes is significantly associated with subsequent smoking abstinence. The association is strongest in socially disadvantaged demographics, including African Americans, low-income individuals, and those who did not attend college.

Multimorbidity, lifestyle, and cognitive function: A cross-cultural study on the role of diabetes, cardiovascular disease, cancer, and chronic respiratory diseases

BACKGROUND

The effect of lifestyle factors on cognitive function related to four major noncommunicable diseases (NCDs) including diabetes, cardiovascular disease, cancer, and chronic respiratory diseases, and the relationship between these NCDs and cognitive function have not been fully studied. We aimed to investigate the longitudinal associations between these NCDs and cognitive function in middle-aged and older people, and the combined effects of lifestyle factors.

METHODS

By employing the data from three large-scale cohort studies from the U.S. Health and Retirement Study (2010-2019), English Longitudinal Study of Aging (2014-2019), and China Health and Retirement Longitudinal Study (2011-2019), this study carried out a multi-cohort analysis to 77, 210 participants. Fixed-effects regression models were used to examine associations between NCD status and cognitive function. Margin plots were used to illustrate the effect of lifestyle factors.

RESULTS

Our findings revealed the dose-dependent association between mounting these NCDs and declining cognitive performance, ranging from one NCD (β = -0.05, 95 % CI: -0.08 to -0.02) to four NCDs (β = -0.51, 95 % CI: -0.75 to -0.28). Decline in cognitive function associated with NCDs was exacerbated with physical inactivity, current smoking status, and an increase in unhealthy lifestyle behaviors.

LIMITATIONS

The observational study design precludes causal interrogation of lifestyles and four NCDs on cognitive function.

CONCLUSIONS

An increasing number of these NCDs were dose-dependently associated with the decline in cognitive function score. Unhealthy lifestyle factors expedite decline in cognitive function linked to these NCDs.

Changes in cigarette smoking behavior among breast cancer and unaffected women - A prospective study in the MARIE cohort

BACKGROUND

Smoking cessation after a cancer diagnosis can reduce adverse cancer treatment outcomes. Whether a breast cancer diagnosis, a cancer commonly seen as unrelated to smoking cigarettes, motivates changes in smoking behavior is not fully understood. We aimed to compare long-term changes at three follow-up times of cigarette smoking behavior in women with breast cancer and baseline age- and region-matched unaffected women.

METHODS

We used longitudinal data from the population-based case-control study MARIE (Mamma Carcinoma Risk Factor Investigation). Women with breast cancer (N = 3813) and unaffected women (N = 7341) aged 50-74 years were recruited from 2002 to 2005. Analyses on changes in smoking were based on data from those who also completed follow-up 1 in 2009-2012, follow-up 2 in 2014-2016 and follow-up 3 in 2020. Multinomial logistic regression for changes (quitting, stable, or start smoking) adjusted for age, study region, education, comorbidities, living situation, and follow-up time, was applied to examine the associations between breast cancer status and changes in smoking behavior.

RESULTS

Women with breast cancer had significantly higher odds than unaffected women of quitting smoking (OR = 1.38, 95 % CI: 1.01-1.89) and lower odds of returning to smoking (OR = 0.29, 95 % CI: 0.09-0.94) at follow-up 1, but were more likely to start or return to smoking at follow-up 2 (OR = 2.11, 95 % CI 1.08-4.15). No significant group differences were found for changes in smoking behavior at follow-up 3.

CONCLUSION

Our findings indicate that short-term changes in smoking behavior can be attributed to a breast cancer diagnosis, but that over time the effect diminishes and changes in smoking no longer differ between breast cancer and breast cancer-free women. To support smoking cessation and to prevent relapse, guidelines to address smoking in cancer care, as well as comprehensive tobacco treatment services, are needed.

Supporting Smokers in Difficult Settings: Suggestions for Better Education and Counseling in Cancer Centers in Jordan

Continued smoking in cancer patients is commonly observed in Jordan. In a country that exhibits some of the highest smoking rates globally, enhancing patient education regarding the value of smoking cessation for cancer care is vital. The objectives of our study were to describe sociodemographic and clinical factors associated with continued smoking in Jordanian smokers after a cancer diagnosis; to identify reasons for smoking and knowledge regarding smoking's impact on care; to examine in a multivariable manner the factors associated with continued smoking, and to accordingly generate patient counseling recommendations. An interviewer-administered survey using the Theoretical Domains Framework was employed. Among 350 subjects (mean age 51.0, median 52.7), approximately 38% of patients had quit or were in the process of quitting; 61.7% remained smokers. Substantial knowledge gaps with regard to the impact of continued smoking on cancer care were observed. Remaining a smoker after diagnosis was associated with being employed, not receiving chemotherapy or surgery, having lower confidence in quitting, and having a lower number of identified reasons for smoking. Interventions to promote cessation in Jordanian cancer patients who smoke should focus on enhancing patient awareness about the impact of smoking in cancer care and raising perceived self-efficacy to quit.

Association between socioeconomic status and health behaviour change before and after non-communicable disease diagnoses: a multicohort study

BACKGROUND

Behavioural risk factors of non-communicable diseases (NCDs) are socially patterned. However, the direction and the extent to which socioeconomic status (SES) influences behaviour changes before and after the diagnosis of NCDs is not clearly understood. We aimed to investigate the influence of SES on behaviour changes (physical inactivity and smoking) before and after the diagnosis of major NCDs.

METHODS

In this multicohort study, we pooled individual-level data from six prospective cohort studies across 17 countries. We included participants who were diagnosed with either diabetes, cardiovascular disease, chronic lung disease, or cancer after recruitment. Participants were surveyed every 2 years. Education and total household wealth were used to construct SES. We measured behaviour changes as whether or not participants continued or initiated physical inactivity or smoking after NCD diagnosis. We used multivariable logistic regression models to estimate odds ratios (ORs), prevalence ratios (PRs), and 95% CIs for the associations between SES and continuation or initiation of unfavourable behaviours.

FINDINGS

We included 8107 individuals recruited between March, 2002, and January, 2016. Over the 4-year period before and after NCD diagnosis, 886 (60·4%) of 1466 individuals continued physical inactivity and 1018 (68·8%) of 1480 participants continued smoking; 1047 (15·8%) of 6641 participants with physical activity before diagnosis initiated physical inactivity after diagnosis and 132 (2·0%) of 6627 non-smokers before diagnosis initiated smoking after diagnosis. Compared with participants with high SES, those with low SES were more likely to continue physical inactivity (244 [70·3%] of 347 vs 23 [50.0%] of 46; PR 1·41 [95% CI 1·05-1·99]; OR 2·28 [1·18-4·41]), continue smoking (214 [75·4%] of 284 vs 39 [60·9%] of 64; PR 1·27 [1·03-1·59]; OR 2·08 [1·14-3·80]), but also to initiate physical inactivity (188 [26·1%] of 720 vs 47 [7·4%] of 639; PR 3·59 [2·58-4·85]; OR 4·31 [3·02 - 6·14]).

INTERPRETATION

Low SES was associated with continuing or initiating physical inactivity and continuing smoking after NCD diagnosis. Reducing socioeconomic inequality in health behaviour changes should be prioritised and integrated into NCD-prevention programmes.

Cessation experiences and quitting perspectives of Jordanian cancer patients who smoke

OBJECTIVES

To describe quitting experiences of cancer patients in a Cancer Center in Jordan; to study patients' perceptions regarding the process of smoking cessation; and to provide insights about patients in this difficult setting in order to inform oncology practitioners with regards to how improve perceptions and skills related to quitting.

METHODS

An Arabic cross-sectional questionnaire was developed to evaluate smoking and quitting behaviors in the context of cancer. The tool used as its framework the Theoretical Domains Framework to capture quitting perceptions of cancer patients who smoke, as well as social, environmental, and system-level factors that influence quitting. Eligible patients who were treated at the Center (both in-patient and out-patient settings) and who were current smokers or who smoked up to the time of cancer diagnosis were eligible. Patients were interviewed between July, 2018 and January 2020 using two versions of the questionnaire: an 'ex-smokers' version, and a 'current smokers' version.

RESULTS

Only a third of subjects (104/350) had been smoke-free for at least 30 days. Both smokers and ex-smokers generally felt that quitting was important, but mean importance and confidence scores (out of 10) were significantly lower in current smokers (8.2 versus 9.1, p-value=0.002; 6.4 versus 8.7, p-value=0.000). Roughly 31% of subjects believed smoking harms were exaggerated and that smoking was not an addiction. About 62% of subjects agreed quitting required skills, and 78.5% felt the steps to quit were clear, but across several listed strategies for quitting, use of these was limited (even in ex-smokers). Among current smokers, roughly a third exhibited forms of cessation fatigue.

CONCLUSION

Jordanian cancer patients who smoke present with limited knowledge about the quitting process. Even when some success is observed, low rates of utilization of specific quitting strategies were observed, highlighting the need for better counseling about quitting.

Using a multilevel implementation strategy to facilitate the screening and treatment of tobacco use in the outpatient urology clinic: A prospective hybrid type I study

BACKGROUND

Urologists frequently treat patients for tobacco-related conditions but infrequently engage in evidence-based practices (EBPs) that screen for and treat tobacco use. Improving the use of EBPs will help to identify smokers, promote cessation, and improve patients' health outcomes.

METHODS

A prospective type I hybrid effectiveness-implementation study was performed to test the feasibility and effectiveness of using a multilevel implementation strategy to improve the use of tobacco EBPs. All urology providers at outpatient urology clinics within the Veterans Health Administration Greater Los Angeles and all patients presenting for a new urology consultation were included. The primary outcome was whether a patient was screened for tobacco use at the time of consultation. Secondary outcomes included a patient's willingness to quit, chosen quit strategy, and subsequent engagement in quit attempts.

RESULTS

In total, 5706 consecutive veterans were seen for a new consultation during the 30-month study period. Thirty-six percent of all visits were for a tobacco-related urologic diagnosis. The percentage of visits that included tobacco use screening increased from 18% (before implementation) to 57% in the implementation phase and to 60% during the maintenance phase. There was significant provider-level variation in adherence to screening. Of all screened patients, 38% were willing to quit, and most patients chose a "cold turkey" method; 22% of the patients elected referral to a formal smoking cessation clinic, and 24% chose telephone counseling. Among those willing to quit, 39% and 49% made a formal quit attempt by 3 and 6 months, respectively.

CONCLUSIONS

A strategy that includes provider education and a customized clinical decision support tool can facilitate provider use of tobacco EBPs in a surgery subspecialty clinic.

Best practices for assessing and reporting tobacco use in urology oncology practice and research

Tobacco use is the cause of several urologic cancers. Persistent use after diagnosis is associated with worse cancer-specific, quality of life, and overall mortality outcomes. Cigarette smoking remains the most common form of tobacco use despite significant population-level decline over the past few decades. The burden of smoking-related urologic disease is under appreciated by urologists and patients which has resulted in gaps in clinical care and limitations to research progress. We sought to summarize evidence-based practices and guideline recommendations for assessing and reporting tobacco use in the clinical and research settings. With a focus on smoking, our two primary goals are: 1) to promote the adoption of standardized and validated measures of tobacco use and 2) to highlight evidence-based strategies for urologists to use in clinical practice.
