Prevalence and correlates of electronic-cigarette use in young adults: Findings from three studies over five years

BACKGROUNDnWe aimed to examine prevalence and correlates of past-month electronic cigarette (e-cigarette) use and use of e-cigarettes to aid a cessation attempt in three samples of young adult smokers recruited online in 2009-2010 (Study 1), 2010-2011 (Study 2), and 2013 (Study 3).nnnMETHODSnParticipants were young adults aged 18 to 25 who smoked at least one cigarette in the previous month (Study 1, N=1987 and Study 2, N=570) or smoked 3 or more days each week and used Facebook 4 or more days per week (Study 3, N=79). We examined both past-month e-cigarette use and ever use of e-cigarettes to quit conventional cigarettes.nnnRESULTSnPrevalence of past-month use of e-cigarettes was higher in each subsequent study: Study 1 (6%), Study 2 (19%), and Study 3 (41%). In multivariate analyses, significant correlates of past-month e-cigarette use were identified for Study 1 (male sex OR=2.1, p=.03; past-year quit attempt OR=1.6, p=.03) and Study 2 (male sex, OR=1.7, p=.03; younger age OR=0.88, p=.05), but not Study 3. In multivariate analyses, significant correlates of ever use of e-cigarette to quit conventional cigarettes were identified for Study 1 (education, OR=1.2, p=.02; smoking within 30min of waking, OR=2.8, p=.02; past year quit attempt OR=4.1, p=.02), and Study 3 (desire to quit smoking, OR=1.3, p=.02), but not Study 2.nnnCONCLUSIONSnE-cigarette use is increasingly common among young adults, particularly men. E-cigarette use for quitting conventional cigarettes appears more common among those more nicotine dependent and interested in quitting.

Smoking, Mental Illness, and Public Health

Tobacco use remains the leading preventable cause of death worldwide. In particular, people with mental illness are disproportionately affected with high smoking prevalence; they account for more than 200,000 of the 520,000 tobacco-attributable deaths in the United States annually and die on average 25 years prematurely. Our review aims to provide an update on smoking in the mentally ill. We review the determinants of tobacco use among smokers with mental illness, presented with regard to the public health HAVE framework of “the host” (e.g., tobacco user characteristics), the “agent” (e.g., nicotine product characteristics), the “vector” (e.g., tobacco industry), and the “environment” (e.g., smoking policies). Furthermore, we identify the significant health harms incurred and opportunities for prevention and intervention within a health care systems and larger health policy perspective. A comprehensive effort is warranted to achieve equity toward the 2025 Healthy People goal of reducing US adult tobacco use to 12%, with attention to all subgroups, including smokers with mental illness.

Patient-provider discussions about lung cancer screening pre- and post-guidelines: Health Information National Trends Survey (HINTS)

OBJECTIVEnIn 2013, the USPSTF issued a Grade B recommendation that long-term current and former smokers receive lung cancer screening. Shared decision-making is important for individuals considering screening, and patient-provider discussions an essential component of the process. We examined prevalence and predictors of lung cancer screening discussions pre- and post-USPSTF guidelines.nnnMETHODSnData were obtained from two cycles of the Health Information National Trends Survey (2012; 2014). The analyzed sample comprised screening-eligible current and former smokers with no personal history of lung cancer (n=746 in 2012; n=795 in 2014). Descriptive and multiple logistic regression analyses were conducted; patient-reported discussion about lung cancer screening with provider was the outcome of interest.nnnRESULTSnContrary to expectations, patient-provider discussions about lung cancer screening were more prevalent pre-guideline, but overall patient-provider discussions were low in both years (17% in 2012; 10% in 2014). Current smokers were more likely to have had a discussion than former smokers. Significant predictors of patient-provider discussions included family history of cancer and having healthcare coverage.nnnCONCLUSIONSnThe prevalence of patient-provider discussions about lung cancer screening is suboptimal.nnnPRACTICE IMPLICATIONSnThere is a critical need for patient and provider education about shared decision-making and its importance in cancer screening decisions.

Trends in Self-reported and Biochemically Tested Marijuana Use Among Pregnant Females in California From 2009-2016

Trends in Self-reported and Biochemically Tested Marijuana Use Among Pregnant Females in California From 2009-2016 Marijuana is the most commonly used illicit drug during pregnancy, and its use is increasing. From 2002 to 2014, the prevalence of self-reported, past-month marijuana use among US adult pregnant women increased from 2.4% to 3.9%.1 In aggregated 2002-2012 data, 14.6% of US pregnant adolescents reported past-month use.2 However, studies are limited to self-reported surveys and likely underestimate use due to social desirability bias and underreporting, leaving the scope of the problem unclear. We investigated trends of prenatal marijuana use from 2009-2016 using data from a large California health care system with universal screening via self-report and urine toxicology.

Use of Electronic Cigarettes Among Cancer Survivors in the U.S.

INTRODUCTIONnThe population-level patterns of electronic cigarette (e-cigarette) use among cancer survivors in the U.S. are unknown. The objective of this study was to examine the prevalence and correlates of e-cigarette use among cancer survivors in a nationally representative sample.nnnMETHODSnA cross-sectional analysis was conducted of the 2014 National Health Interview Survey of the U.S. non-institutionalized civilian population. The main study outcomes were the prevalence and correlates of ever and current e-cigarette use among adults with self-reported history of cancer, excluding non-melanoma skin cancer (N=2,695). Multivariable logistic regression analyses examined whether e-cigarette use differed by cigarette smoking status and demographic subgroups. The analyses were performed in 2015.nnnRESULTSnThe prevalence of e-cigarette use among adult cancer survivors was lower than the general population: 2.8% of cancer survivors reported currently using e-cigarettes and an additional 6.3% had previously used e-cigarettes but were not currently using them. Use of e-cigarettes was most common among cancer survivors who currently smoked cigarettes: 34.3% of current smokers were ever e-cigarette users and 15.6% were current e-cigarette users, compared with former smokers (2.7% ever and 1.4% current e-cigarette users) and never smokers (small sample/estimates unavailable).nnnCONCLUSIONSnE-cigarettes are not part of current evidence-based smoking-cessation strategies. However, the finding that cancer survivors who currently smoke cigarettes are more likely to use e-cigarettes highlights the importance of addressing e-cigarette use in patient-provider communications around tobacco cessation.

Drinking experience uncovers genetic influences on alcohol expectancies across adolescence

AIMSnTo test whether drinking onset moderates genetic and environmental contributions to individual differences in the etiology of alcohol expectancies across adolescence.nnnDESIGNnLongitudinal twin design.nnnSETTINGnCommunity sample from Los Angeles, CA, USA.nnnPARTICIPANTSnA total of 1292 male and female twins, aged 11–18years, were assessed at 1 (n = 440), 2 (n = 587) or 3 (n = 265) occasions as part of the risk factors for the Antisocial Behavior Twin Study.nnnMEASUREMENTSnSocial behavioral (SB) alcohol expectancies were measured using an abbreviated version of the Social Behavioral subscale from the Alcohol Expectancy Questionnaire for adolescents (AEQ-A). Drinking onset was defined as >1 full drink of alcohol.nnnFINDINGSnAlcohol expectancies increased over age and the increase became more rapid following onset of drinking. The importance of genetic and environmental influences on SB scores varied with age and drinking status, such that variation prior to drinking onset was attributed solely to environmental influences, whereas all post-onset variation was attributed to genetic influences. Results did not differ significantly by sex.nnnCONCLUSIONnOnly environmental factors explain beliefs about the social and behavioral consequences of alcohol use prior to drinking onset,whereas genetic factors explain an increasing proportion of the variance in these beliefs after drinking onset.

Smoking Status and Opioid-related Problems and Concerns Among Men and Women on Chronic Opioid Therapy.

Objectives: Smokers on chronic opioid therapy (COT) for noncancer pain use prescription opioids at higher dosages and are at increased risk for opioid misuse and dependence relative to nonsmokers. The current study aims to assess whether smoking is associated with problems and concerns with COT from the perspective of the patient. Materials and Methods: In a large sample (N=972) of adult patients prescribed opioids for chronic noncancer pain, we examined sex-specific associations between smoking status and patient perceptions of problems and concerns with COT using regression analyses, adjusting for covariates. Results: The sample self-identified as 27% current smokers, 44% former smokers, and 29% never smokers. Current smoking (vs. never smoking) was associated with increased odds of an opioid use disorder among males and females, and higher daily opioid dose among males only. Current and former smokers reported significantly fewer problems with opioids relative to never smokers, and this was driven primarily by lower endorsement of problems that are affected by the stimulant properties of nicotine (eg, difficulties thinking clearly, felt less alert or sleepy). Discussion: This study contributes to an understanding of perceived problems and concerns with COT among current, former, and never smokers with chronic noncancer pain. Results suggest that current and former smokers may be a difficult population to target to decrease COT, given that they perceive fewer problems with prescription opioid use, despite higher odds of having an opioid use disorder (males and females) and greater opioid doses (males only).

Documentation of e-cigarette use and associations with smoking from 2012 to 2015 in an integrated healthcare delivery system

It is unclear whether use of electronic nicotine delivery systems (ENDS) precedes cigarette smoking initiation, relapse, and/or quitting. Healthcare systems with electronic health records (EHRs) provide unique data to examine ENDS use and changes in smoking. We examined the incidence of ENDS use (2012-2015) based on clinician documentation and tested whether EHR documented ENDS use is associated with twelve-month changes in patient smoking status using a matched retrospective cohort design. The sample was Kaiser Permanente Northern California (KPNC) patients aged ≥12 with documented ENDS use (Nu202f=u202f7926); 57% were current smokers, 35% former smokers, and 8% never-smokers. ENDS documentation incidence peaked in 2014 for current and former smokers and in 2015 for never-smokers. We matched patients with documented ENDS use to KPNC patients without documented ENDS use (Nu202f=u202f7926) on age, sex, race/ethnicity, and smoking status. Documented ENDS use predicted the likelihood of smoking in the following year. Among current smokers, ENDS use was associated with greater odds of quitting smoking (ORu202f=u202f1.17, 95%CIu202f=u202f1.05-1.31). Among former smokers, ENDS use was associated with greater odds of smoking relapse (ORu202f=u202f1.53, 95%CIu202f=u202f1.22-1.92). Among never-smokers, ENDS use was associated with greater odds of initiating smoking (ORu202f=u202f7.41, 95%CIu202f=u202f3.14-17.5). The overall number of current smokers at 12u202fmonths was slightly higher among patients with (Nu202f=u202f3931) versus without (Nu202f=u202f3850) documented ENDS use. Results support both potential harm reduction of ENDS use (quitting combustibles among current smokers) and potential for harm (relapse to combustibles among former smokers, initiation for never-smokers).

Do you vape? Leveraging electronic health records to assess clinician documentation of electronic nicotine delivery system use among adolescents and adults.

Use of electronic nicotine delivery systems (ENDS) has increased substantially over the past decade. However, unlike smoking, which is systematically captured by clinicians through routine screening and discrete documentation fields in the electronic health record (EHR), unknown is the extent to which clinicians are documenting patients use of ENDS. Data were gathered from medical visits with patients aged 12 and older (N=9,119; 55% male) treated in a large, integrated healthcare system. We used natural language processing to assess the incidence rates of clinician documentation of patients ENDS use in unstructured tobacco comments in the EHR, and the words most frequently documented in relation to ENDS, from 2006-2015. ENDS documentation in the EHR increased dramatically over time (from 0.01 to 9.5 per 10,000 patients, p<0.0001), particularly among adults aged 18-24 and 25-44. Most prevalent were e-cig, electronic cigarettes, and vape, with much variation in spelling and phrasing of these words. Records of adolescent and young adult patients were more likely to contain the word vape, and less likely to have e-cig and electronic cigarette than records of adults (ps<0.0001). The relatively low observed number of patients with ENDS terms in the EHR suggested vast under documentation. While healthcare providers are increasingly documenting patients use of ENDS in the EHR, overall documentation rates remain low. Discrete EHR fields for standard screening and documentation of ENDS that reflect the language used by patients would provide more complete longitudinal population-level surveillance of ENDS use and its association with short- and long-term health outcomes.
