Associations between smoking cessation and anxiety and depression among U.S. adults

Many studies have shown a relationship between smoking and depression. However, few studies have examined the association between current depression and smoking and even fewer used large cross-sectional data to support these findings. Using the 2006 Behavioral Risk Factor Surveillance System data (n = 248,800), we compared rates of lifetime depression, lifetime anxiety, current depression, and current depressive symptoms among smokers who unsuccessfully attempted to quit (unsuccessful quitters), former smokers (successful quitters), and smokers who made no attempts to quit (non-quitters).Unsuccessful quitters experienced more lifetime depression and anxiety than non-quitters (OR = 1.2; 95% CI, 1.0–1.4), whereas successful quitters experienced less (OR = 0.7, 95% CI, 0.6–0.8). Current depression prevalence was 14.3% among non-quitters, 18.8% among unsuccessful quitters, and 8.0% among successful quitters. On average, unsuccessful quitters also experienced more days of depressive symptoms during the previous month than either non-quitters or successful quitters.Our results suggest that smokers who attempt to quit unsuccessfully may experience lifetime depression as well as current depression at a higher rate than other smokers and former smokers.     

Psychosocial and metabolic function by smoking status in individuals with binge eating disorder and obesity

Individuals with binge eating disorder (BED) report smoking to control appetite and weight. Smoking in BED is associated with increased risk for comorbid psychiatric disorders, but its impact on psychosocial functioning and metabolic function has not been evaluated. Participants were 429 treatment-seeking adults (72.4% women; mean age 46.2 ± 11.0 years old) with BED comorbid with obesity. Participants were categorized into current smokers (n = 66), former smokers (n = 145), and never smokers (n = 218). Smoking status was unrelated to most historical eating/weight variables and to current eating disorder psychopathology. Smoking status was associated with psychiatric, psychosocial, and metabolic functioning. Compared with never smokers, current smokers were more likely to meet lifetime diagnostic criteria for alcohol (OR = 5.51 [95% CI = 2.46–12.33]) and substance use disorders (OR = 7.05 [95% CI = 3.37–14.72]), poorer current physical quality of life, and increased risk for metabolic syndrome (OR = 1.80 [95% CI = 0.97–3.35]) and related metabolic risks (reduced HDL, elevated total cholesterol). On the other hand, the odds of meeting criteria for lifetime psychiatric comorbidity or metabolic abnormalities were not significantly greater in former smokers, relative to never smokers. Our findings suggest the importance of promoting smoking cessation in treatment-seeking patients with BED and obesity for its potential long-term implications for psychiatric and metabolic functioning.     

Prevalence and correlates of a lifetime cannabis use disorder among pregnant former tobacco smokers

BackgroundFollowing tobacco and alcohol, cannabis is the most commonly used substance during pregnancy. Given the high prevalence of concurrent cannabis and tobacco use as well as the health consequences associated with prenatal substance use, we sought to document the relative contributions of psychosocial and psychiatric factors commonly associated with cannabis use in predicting a lifetime cannabis use disorder (CUD) among women who had quit smoking tobacco as a result of pregnancy.MethodsPregnant former tobacco smokers (n = 273) enrolled in a larger randomized controlled trial for postpartum tobacco relapse prevention completed semi-structured psychiatric interviews and self-reported demographic, pregnancy, health, psychosocial, and tobacco use factors during their third trimester of pregnancy.ResultsIn total, 14% (n = 38) of women met criteria for a lifetime CUD. The strongest predictors of a lifetime CUD were a history of having multiple psychiatric disorders (OR = 36.44; 95% CI = 5.03–264.27; p < 0.001) followed by a lifetime alcohol use disorder (OR = 3.54; 95% CI = 1.27–9.87; p < 0.05). In addition, more frequent attempts to quit smoking tobacco (OR = 1.12; 95% CI = 1.01–1.25; p < 0.05) and lower self-efficacy about weight management after quitting smoking tobacco (OR = 0.78; 95% CI = 0.62–0.97; p < 0.05) also were significantly associated with a lifetime CUD.ConclusionsWomen with a history of both cannabis and tobacco dependence may represent a subset of women who need more specialized treatment during the perinatal period to improve substance use outcomes.     

Transitioning from adequate to inadequate sleep duration associated with higher smoking rate and greater nicotine dependence in a population sample

IntroductionInadequate sleep (≤ 6 and ≥ 9 h) is more prevalent in smokers than non-smokers but the extent to which sleep duration in smokers relates to smoking behaviors and cessation outcomes, is not yet clear. To begin to address this knowledge gap, we investigated the extent to which sleep duration predicted smoking behaviors and quitting intention in a population sample.MethodsData from current smokers who completed the baseline (N = 635) and 5-year follow-up (N = 477) assessment in the United Kingdom Biobank cohort study were analyzed. Multivariable regression models using smoking behavior outcomes (cigarettes per day, time to first cigarette, difficulty not smoking for a day, quitting intention) and sleep duration (adequate (7–8 h) versus inadequate (≤ 6 and ≥ 9 h) as the predictor were generated. All models adjusted for age, sex, race, and education.ResultsWorsening sleep duration (adequate to inadequate) predicted a more than three-fold higher odds in increased cigarettes per day (OR = 3.18; 95% CI = 1.25–8.06), a more than three-fold increased odds of not smoking for the day remaining difficult (OR = 3.90; 95% CI = 1.27–12.01), and a > 8-fold increased odds of higher nicotine dependence (OR = 8.98; 95% CI = 2.81–28.66). Improving sleep duration (i.e., inadequate to adequate sleep) did not predict reduced cigarette consumption or nicotine dependence in this population sample.ConclusionTransitioning from adequate to inadequate sleep duration may be a risk factor for developing a more “hard-core” smoking profile. The extent to which achieving healthy sleep may promote, or optimize smoking cessation treatment response, warrants investigation.     

The long-term effects of childhood maltreatment experiences on subsequent illicit drug use and drug-related problems in young adulthood

ObjectivesThe objective of this study was to examine the associations between (a) childhood maltreatment (i.e., physical abuse, sexual abuse, and neglect) and subsequent illicit drug use and (b) childhood maltreatment and drug-related problems in young adulthood.MethodsWave 1 and Wave 3 public-use data from the National Longitudinal Study of Adolescent Health were used. Logistic regressions, controlling for adolescent drug use and other important family and peer contextual processes, were estimated to determine the associations between (a) childhood maltreatment experiences and subsequent illicit drug use and (b) childhood maltreatment and drug-related problems in young adulthood.ResultsAmong the participants, 31.9% reported some form of childhood maltreatment. Childhood physical abuse was associated with a 37% (OR = 1.37; 95% CI = 1.04, 1.80) increase in illicit drug use during the 30 days prior to the Wave 3 survey, a 48% (OR = 1.48; 95% CI = 1.16, 1.89) increase in illicit drug use during the year prior to the Wave 3 survey, and a 96% (OR = 1.96; 95% CI = 1.40, 2.76) increase in drug-related problems in young adulthood. The latter two associations persisted even after controlling for illicit drug use in adolescence. Neglect among females was associated with a higher likelihood of past year illicit drug use in young adulthood (OR = 1.31; 95% CI = 1.002, 1.71). However, this association was not significant once the effect of illicit drug use in adolescence was statistically controlled for.ConclusionsThe present findings suggest that childhood maltreatment is related to subsequent illicit drug use and drug-related problems in young adulthood and that some of these associations differ by gender. Implications for preventive intervention are discussed.     

Get with the program: Adherence to a smartphone app for smoking cessation

IntroductionAlthough engagement is generally predictive of positive outcomes in technology-based behavioral change interventions, engagement measures remain largely atheoretical and lack treatment-specificity. This study examines the extent to which adherence measures based on the underlying behavioral change theory of an Acceptance and Commitment Therapy (ACT) app for smoking cessation predict smoking outcomes, and user characteristics associated with adherence.MethodsStudy sample was adult daily smokers in a single arm pilot study (n = 84). Using the app's log file data, we examined measures of adherence to four key components of the ACT behavior change model as predictors of smoking cessation and reduction. We also examined baseline user characteristics associated with adherence measures that predict smoking cessation.ResultsFully adherent users (24%) were over four times more likely to quit smoking (OR = 4.45; 95% CI = 1.13, 17.45; p = 0.032). Both an increase in tracking the number of urges passed (OR = 1.02; 95% CI = 1.00, 1.03; p = 0.043) and ACT modules completed (OR = 1.27; 95% CI = 1.01, 1.60; p = 0.042) predicted cessation. Lower baseline acceptance of cravings was associated with over four times higher odds of full adherence (OR = 4.59; 95% CI = 1.35, 15.54; p = 0.014).ConclusionsFull adherence and use of specific ACT theory-based components of the app predicted quitting. Consistent with ACT theory, users with low acceptance were most likely to adhere to the app. Further research is needed on ways to promote app engagement.     

Levels of physical dependence on tobacco among adolescent smokers in Cyprus

PurposeThe purpose of this study is to assess tobacco dependence among Cypriot adolescents and examine its association to cigarette consumption and attitudes towards smoking.MethodsThe current study used cross-sectional data from the 2011 Cyprus Global Youth Tobacco Survey which adopted multistage cluster sampling methods to select adolescents registered in middle and high schools in Cyprus. Tobacco use, physical dependence on tobacco, and attitudes towards tobacco use were measured in 187 adolescents aged 13–18 years old who reported that they had smoked at least once in the preceding 30 days. Physical dependence was assessed using the Levels of Physical Dependence scale.ResultsPhysical dependence was present in 86% of the adolescent smokers. The mean latency to needing among smokers in the highest dependence group was 101 h. Significant associations were observed between physical dependence and the perceived difficulty in quitting (OR = 13.1, 95% CI: 4.0, 43.0) as well as the expectation to continue smoking for the next five years (OR = 3.3, 95% CI: 1.3, 8.4). Significant associations were also observed between physical dependence and the number of smoking days per month, daily smoking, daily cigarette consumption, lifetime cigarette consumption, and perceived difficulty in abstaining from smoking for one week.ConclusionsPhysical dependence provides a symptom-based approach to assess dependence and it is a strong predictor of adolescents' perceptions of their ability to quit or to refrain from smoking for a week. Physical dependence on tobacco was highly prevalent among adolescent smokers in Cyprus and it was associated with greater perceived difficulty in quitting. Interventions targeting adolescent smoking must account for the high prevalence of physical dependence.     

Influence of point-of-sale tobacco displays and plain black and white cigarette packaging and advertisements on adults: Evidence from a virtual store experimental study

IntroductionWe examined the potential impact of banning tobacco displays and mandating plain packaging and cigarette advertisements at the point of sale (POS) on adult outcomes.MethodsA virtual convenience store was created with scenarios in which the tobacco product display was either fully visible (status quo) or enclosed behind a cabinet (display ban), and cigarette packs and advertisements were either in full color (status quo) or black and white, text only (plain). A national convenience sample of 1313 adult current smokers and recent quitters was randomized to 1 of 4 conditions and given a shopping task to complete in the virtual store. Main outcomes were participants' self-reported urge to smoke and tobacco purchase attempts in the virtual store.ResultsCompared with recent quitters in the status quo conditions, recent quitters in the display ban condition had lower urges to smoke (β = − 4.82, 95% CI = − 8.16–− 1.49, p < 0.01). Compared with current smokers in the status quo conditions, smokers in the display ban conditions were less likely to attempt to purchase cigarettes in the virtual store (OR = 0.05, 95% CI = 0.03–0.08, P < 0.01). Smokers exposed to plain packs and ads were significantly less likely to attempt to purchase cigarettes (OR = 0.31, 95% CI = 0.20–0.47, P < 0.01) than those exposed to color packs and ads.ConclusionsPolicies that ban the display of tobacco products or require plain packaging and advertising at the POS may help reduce adult smoking.     

Trends in cigarette use,by serious psychological distress status in the United States, 1998–2013

ObjectivesThe study compared trends in current and heavy cigarette smoking between adults with and without serious psychological distress (SPD).MethodsThis study examined data from 480,024 adults aged 18 years or older in the 1998–2013 National Health Interview Survey (NHIS) public use files. SPD is defined as having a Kessler-6 score of 13 or higher in the past month. Trends in the prevalence of current smoking and heavy smoking for 2-year time periods were assessed among those with versus those without SPD using logistic regression; tests of interaction terms determined whether smoking trends differed by SPD status.ResultsThe prevalence of current smoking decreased over time among adults without SPD (adjusted odds ratio [AOR] = 0.97, 95% CI = 0.97–0.98), but remained stable among adults with SPD (AOR = 1.01, 95% CI = 0.99–1.03). Both groups had significant declines in heavy smoking over time; however, the rates of decline were greater among adults without versus with SPD (AOR = 0.87, 95% CI = 0.86–0.88 and AOR = 0.91, 95% CI = 0.88–0.94, respectively).ConclusionsThe prevalence of current smoking is not declining among adults with SPD, and the prevalence of heavy smoking is not declining as quickly among adults with SPD as compared with those without SPD. Smoking cessation efforts may need to target these populations and tailor programs accordingly.     

Increased self-efficacy to quit and perceived control over withdrawal symptoms predict smoking cessation following nicotine dependence treatment

AimTo examine changes in nicotine withdrawal, nicotine craving, self-efficacy to quit smoking, and perceived control over withdrawal symptoms as predictors of smoking cessation following behavioral counseling and nicotine replacement therapy in a sample of smokers.Design and settingThe data were ascertained from a randomized effectiveness trial comparing nicotine patch to nicotine lozenge. Predictors of smoking cessation were assessed at baseline and 5 weeks post-baseline, and 24-hour point prevalence abstinence, biochemically confirmed, was assessed at the end-of-treatment (week 15) and 6 months after a target quit date (week 27).Participants642 treatment-seeking smokers randomized to 12 weeks of nicotine patch or nicotine lozenge.FindingsParticipants who showed a greater increase in self-efficacy to quit smoking (OR = 1.09, 95% CI: 1.02–1.16, p = .01) and perceived control over withdrawal symptoms (OR = 1.02, 95% CI: 1.00–1.04, p = .05) were significantly more likely to have quit smoking at week 15. Participants who showed a greater increase in self-efficacy to quit smoking (OR = 1.04, 95% CI: 1.01–1.06, p = .01) were significantly more likely to have quit smoking at week 27. Changes in withdrawal symptoms and craving were not related to week 15 or week 27 abstinence rates.ConclusionsThe results highlight two relatively under-studied potential psychological predictors of abstinence following treatment for nicotine dependence. Behavioral counseling interventions to promote smoking cessation should help smokers develop confidence in their ability to quit smoking and increase their sense of control over withdrawal symptoms to increase their chances for cessation.     

Respiratory problems and anxiety sensitivity in smoking lapse among treatment seeking smokers

PurposeThe current study examined whether the interaction of lower respiratory symptoms and anxiety sensitivity is related to smoking lapse in the context of smoking cessation.MethodParticipants were adult daily smokers (N = 60) exposed to the World Trade Center (WTC) disaster who were in a smoking cessation treatment program (75.0% male, 50.6 years old [SD = 9.2], and current smoking rate was 17.6 cigarettes per day (SD = 10.6).ResultsResults indicated that the interaction between lower respiratory symptoms and anxiety sensitivity was a significant predictor of greater risk for lapse (i.e., lower survival time; B = 0.005, OR = 1.01, p = 0.039). Follow-up analysis showed that greater respiratory symptoms were a significant predictor of lapse risk among those with high (B = 0.116, OR = 1.12, p = 0.025), but not those with low (B = − 0.048, OR = 0.95, p = 0.322), levels of anxiety sensitivity.DiscussionThe findings from the current study suggest that smokers with greater respiratory symptoms and higher levels of anxiety sensitivity may be associated with early lapse to smoking following smoking cessation treatment. Future work has the potential to inform the development of tailored cessation interventions for smokers who experience varying levels of lower respiratory symptoms and anxiety sensitivity.     

E-cigarette advertisements,and associations with the use of e-cigarettes and disapproval or quitting of smoking: Findings from the International Tobacco Control (ITC) Netherlands Survey

BackgroundMuch attention has been directed towards the possible effects of e-cigarette advertisements on adolescent never smokers. However, e-cigarette advertising may also influence perceptions and behaviours of adult smokers. The aim of our study was to examine whether noticing e-cigarette advertisements is associated with current use of e-cigarettes, disapproval of smoking, quit smoking attempts, and quit smoking success.MethodsWe used longitudinal data from two survey waves of the ITC Netherlands Survey among smokers aged 16 years and older (n = 1198). Respondents were asked whether they noticed e-cigarettes being advertised on television, on the radio, and in newspapers or magazines in the previous 6 months.ResultsThere was a significant increase in noticing e-cigarette advertisements between 2013 (13.3%) and 2014 (36.0%), across all media. The largest increase was for television advertisements. There was also a substantial increase in current use of e-cigarettes (from 3.1% to 13.3%), but this was not related to noticing advertisements in traditional media (OR = 0.99, p = 0.937). Noticing advertisements was bivariately associated with more disapproval of smoking (Beta = 0.05, p = 0.019) and with a higher likelihood of attempting to quit smoking (OR = 1.37, p = 0.038), but these associations did not reach significance in multivariate analyses. There was no significant association between noticing advertisements and quit smoking success in either the bivariate or multivariate regression analysis (OR = 0.92, p = 0.807).ConclusionNoticing e-cigarette advertisements increased sharply in the Netherlands between 2013 and 2014 along with increased e-cigarette use, but the two appear unrelated. The advertisements did not seem to have adverse effects on disapproval of smoking and smoking cessation.     

Safe havens and rough waters: Networks,place, and the navigation of risk among injection drug-using Malaysian fishermen

BackgroundHIV prevalence among Malaysian fishermen is ten times that of the general population. Fishing boats are a key place where drug use occurs, but we know little about how these environments shape HIV risk behaviour. Utilizing Rhodes’ ‘risk environment’ framework, we assessed drug use contexts and how characteristics of place associated with fishing and fishermen's social networks served as key axes along which drug use and HIV risk behaviour occurred.MethodsData were collected during 2009–2011 in Kuantan, a fishing port on the eastern coast of Malaysia, and include 28 in-depth interviews and 398 surveys collected using RDS. Logistic regression was used to determine the effect of occupational, network and risk environment characteristics on unsafe injection behaviour and access to clean needles/syringes; qualitative data were coded and analyzed thematically.ResultsDrug injecting was common and occurred on boats, often with other crewmembers. Captains and crewmembers were aware of drug use. Unsafe injection practices were significantly associated with having a larger proportion of drug injectors in network (OR = 3.510, 95% CI = 1.053–11.700) and having a captain provide drugs for work (OR = 2.777, 95% CI = 1.018–7.576). Size of fishermen network (OR = 0.987, 95% CI = 0.977–0.996), crewmembers’ knowledge of drug use (OR = 7.234, 95% CI = 1.430–36.604), and having a captain provide drugs for work (OR = 0.134, 95% CI = 0.025–0.720) predicted access to clean needles/syringes. Qualitative analyses revealed that occupational culture and social relationships on boats drove drug use and HIV risk.ConclusionsWhile marginalized in broader society, the acceptance of drug use within the fishing community created occupational networks of risk. Fishing boats were spaces of both risk and safety; where drug users participated in the formal economy, but also where HIV risk behaviour occurred. Understanding the interplay between social networks and place is essential for developing HIV prevention and harm reduction policies appropriate for the unique needs of this fishing population.     

Predictors of heroin abstinence in opiate substitution therapy in heroin-only users and dual users of heroin and crack

AimsTo analyse predictors of heroin abstinence in opiate substitution therapy (OST) based on frequency of crack use and its interactions with other predictors in a clinical non-experimental setting.DesignRetrospective study.SettingA community drug service in London, UK.Participants325 clients starting OST between 2010 and 2014 (197 methadone and 128 buprenorphine).MeasurementsLogistic regression models (a general model and separate models for methadone and buprenorphine) assessed demographic and clinical data as predictors of heroin abstinence at one year after treatment start (or at the date of transfer to another service).FindingsFor the general model participants choosing methadone were more likely to use heroin at follow up (OR = 2.36, 95% CI: 1.40–3.17) as were daily crack users on methadone (OR = 2.62, 95% CI: 0.96–7.16).For the methadone model only daily crack use predicted heroin use at follow up (OR = 2.62, 95% CI: 0.96–7.16).For buprenorphine, higher amounts of baseline heroin use, lower buprenorphine dose and daily drinking predicted heroin use at follow up (OR = 0.85, 95% CI: 0.75–0.95; OR = 1.31, 95% CI: 1.06–1.60 and OR = 6.04, 95% CI: 1.26–28.92). Both use of cannabis and depression increased likelihood of heroin abstinence for clients not using crack compared to occasional (OR = 6.68, 95% CI: 0.37–119.59; OR = 106.31, 95% CI: 3.41–3313.30) and daily (OR = 57.49 (95% CI: 2.37–1396.46; OR = 170.99 (95% CI: 4.61–6339.47) users.ConclusionsMost of the predictors in the general model were found significant only in the buprenorphine but not in the methadone model, suggesting that a general model has little predictive value. Crack use was a significant predictor of heroin abstinence at follow up in all models, however for buprenorphine only when depression or cannabis use was present. Further research is needed to assess effective treatment approaches for the growing population of dual users.     

Social cohesion and the smoking behaviors of adults living with children

IntroductionThe smoking behavior of adults can negatively impact children through exposure to environmental tobacco smoke and by modeling this unhealthy behavior. Little research has examined the role of the social environment in smoking behaviors of adults living with children. The present study specifically analyzed the relationship between social cohesion and smoking behaviors of adults living with children.MethodsData from the 2009 California Health Interview Survey, a random-digit dial cross-sectional survey of California Adults, were used. Adults living with children reported their levels of social cohesion and smoking behaviors (N = 13,978). Logistic regression models were used to predict odds of being a current smoker or living in a household in which smoking was allowed, from social cohesion.ResultsOverall, 13% of the sample was current smokers and 3.74% lived in households in which smoking was allowed. Logistic regression models showed that each one-unit increase in social cohesion is associated with reduced odds of being a current smoker (AOR = 0.92; 95% CI = 0.85–0.99) and reduced odds of living in a household in which smoking is allowed (AOR = 0.84; 95% CI = 0.75–0.93), after controlling for sociodemographic characteristics.ConclusionsAmong adults living with children, higher social cohesion is associated with a lower likelihood of both being and smoker and living in a home where smoking is allowed. Thus, future research is needed to better understand mechanisms that explain the relationship between social cohesion and smoking-related behavior in order to prevent smoking-related health consequences and smoking initiation among children and adults.     

Panic attacks and smoking cessation among cancer patients receiving smoking cessation treatment

ObjectiveLittle is known about factors associated with smoking cessation in cancer patients. This study examined the impact of panic attacks on smoking abstinence likelihood among cancer patients receiving tobacco cessation treatment.MethodThe relationship of panic attacks to 7-day point-prevalence abstinence at mid-treatment, end of treatment, and 6-month post-end of treatment were examined among cancer patients (N = 2255 patients; 50.1% female; M_age = 54.9, SD = 11.0) who received counseling and pharmacotherapy for smoking cessation. Panic attack history indexed by two questions from the Patient Health Questionnaire (PHQ). Point-prevalence abstinence was assessed via the Timeline Follow-Back.ResultsCancer patients with a history of panic attacks, (n = 493, 21.9%) relative to those without, were less likely to be abstinent at mid-treatment (OR = 0.79, CI_95% = 0.64–0.98) and end of treatment (OR = 0.72, CI_95% = 0.58–0.89). After adjusting for significant covariates, panic attack history remained predictive of decreased abstinence likelihood at end of treatment (OR = 0.78, CI_95% = 0.62–0.99).ConclusionsPanic attacks may be related to poorer cessation outcome during smoking treatment among cancer patients, and may be usefully assessed and targeted for intervention.     

Gender differences in the use of alcohol and prescription drugs in relation to job insecurity. Testing a model of mediating factors

BackgroundThe results of several studies suggest that economy-related stressors are less distressing for women compared with men. This study proposed to examine the relationship of perceived job insecurity with the use of licit drugs using a theoretical model that considered antecedents and mediators of this association, in order to identify differences between working men and women.MethodsUsing information from the Catalan Health Survey (2010–2014), we selected working individuals aged 16–64 who were primary providers of household income (N = 5315). The outcomes were two measures of alcohol consumption (heavy drinking and binge drinking) and the use of hypnotics/sedatives. As antecedents of the exposure to job insecurity we considered the type of contractual relationship and occupational class. The mediating factors were poor mental health, household structure and the hours of housework per week. The theoretical model was assessed using path analysis where the moderating effect of gender was considered in all the associations.ResultsNo differences in the prevalence of job insecurity were found between men and women (17%). Job insecurity (Odds ratio [OR] = 1.35, 95% confidence interval [CI] = 1.23–1.48) and house workload (OR = 1.01, 95% CI = 1.00–1.02) were positively associated with poor mental health, with no significant interactions with gender. Poor mental health was significantly associated with binge drinking (OR = 1.23, 95% CI = 1.13–1.33) and with the use of hypnotics/sedatives (OR = 1.71, 95% CI = 1.53–1.91). House workload showed a direct negative association with binge drinking (OR = 0.99, 95% CI = 0.98–1.00), while those in households with no children were more likely to be binge drinkers, with no significant interactions with gender. An alternative model had better fitting results for heavy drinking.ConclusionNo gender differences were found in the association of job insecurity with mental health nor with the use of substances among primary providers of household income, emphasising the importance of social roles when assessing differences in mental health among men and women.     

Breakdowns of eye movement control toward smoking cues in young adult light smokers

BackgroundMany studies suggest that dependent smokers have a preference or attentional bias toward smoking cues. The purpose of this study was to test the ability of infrequent non-dependent light smokers to control their eye movements by look away from smoking cues. Poor control in the lightest of smokers would suggest nicotine cue-elicited behavior occurring even prior to nicotine dependency as measured by daily smoking.Methods17 infrequent non-dependent light smokers and 17 lifetime non-smokers performed an antisaccade task (look away from suddenly appearing cue) on smoking, alcohol, neutral, and dot cues.ResultsThe light smokers, who were confirmed light smokers and non-dependent (M_{Faegerström Dependency Score} = 0.35), were significantly worse at controlling their eye movements to smoking cues relative to both neutral cues (p < .04) and alcohol cues (p < .02). Light smokers made significantly more errors to smoking cues than non-smokers (p < .004).ConclusionsThese data suggest that prior to developing clinical symptoms of severe dependence or progressing to heavier smoking (e.g., daily smoking), the lightest of smokers are showing a specific deficit in control of nicotine cue-elicited behavior.     

The relationship of waterpipe use with cigarette smoking susceptibility and nicotine dependence: A cross-sectional study among Hong Kong adolescents

IntroductionWaterpipe smoking has become increasingly popular in adolescents. We examined the association of waterpipe smoking with cigarette smoking susceptibility and nicotine dependence among adolescents in Hong Kong.MethodsWe analyzed the data of School-based Survey on Smoking among Students 2012/13 from a representative sample of 45,857 secondary school students (US grades 7–12) in Hong Kong. Among never cigarette smokers (n = 37,740), we conducted chi-square test to compare cigarette smoking susceptibility by current (past 30-day) waterpipe smoking status, and used multivariate logistic regression to examine the association between current waterpipe smoking and cigarette smoking susceptibility controlling for age, sex, peer cigarette smoking, and living with a cigarette smoker. Then we conducted chi-square test and multivariate logistic regression among current cigarette smokers (n = 1694) to examine the relationship of current waterpipe smoking with two nicotine dependence outcomes, including heavier smoking (≥ 5 cigarettes/day) and first cigarette within 30 min of waking, controlling for demographics and the number of smoking days in the past 30 days.ResultsAmong never cigarette smokers, current waterpipe use was associated with cigarette smoking susceptibility (adjusted odds ratio [AOR] = 3.58, 95% confidence interval [CI]: 1.61–7.97). Of current cigarette smokers, waterpipe use was associated with heavier smoking (AOR = 1.56, 95% CI: 1.00–2.43) and first cigarette within 30 min of waking (AOR = 2.08, 95% CI: 1.35–3.19).ConclusionsSurveillance, prevention, and intervention programs should address waterpipe use in addition to cigarette smoking. Educational programs need to inform youth about the harmful and addictive effects of waterpipe smoking. Public health campaigns deglamourizing waterpipe use may help reduce waterpipe smoking among youth.
