Background and Aims: Alcohol use is increasing among women in mid‐life concurrently with societal changes in timing of parenthood and changing cultural norms, which may influence alcohol use. The aim of this study was to determine if age of first parenting was associated with excessive drinking [i.e. past 2‐week binge drinking and past 5‐year alcohol use disorder (AUD) symptoms] among women during mid‐life in the United States and to determine if there were pronounced cohort effects influencing these relationships. Design: This was a retrospective cohort, longitudinal study. Setting, Participants and Measurements: Data were drawn from the Monitoring the Future survey, an annual ongoing survey of high school students' substance use behaviors in the United States. Participants were women who completed the age 35 survey between 1993 and 2019, corresponding to high school senior years 1976–2002 (n = 9988). Past 2‐week binge drinking and past 5‐year AUD symptoms were self‐reported. Age of first parenting was self‐reported. Findings Binge drinking and AUD symptoms were higher among women in recent than in older cohorts. Women from the 2018–19 cohort had increased odds of binge drinking [odds ratio (OR) = 1.73, 95% confidence interval (CI) = 1.41–2.12] and AUD symptoms (OR = 1.51, CI = 1.27–1.80) relative to women from the 1993–97 cohort. Throughout cohorts, there was an inverse association between transition to parenthood and excessive drinking outcomes (e.g. range for ORs for binge drinking among those without children compared with those who had had children between the ages of 18 and 24: 1.22–1.55). Simultaneously, there was a population shift towards delaying parenting in recent cohorts (i.e. 54% of women in the 1993–97 cohort had children before age 30 compared with 39% in the two recent cohorts), increasing the size of the group at highest risk for excessive drinking. Conclusions: In the United States, subgroups of women at highest risk of excessive drinking appear to be expanding, probably supported in part by a trend towards delayed parenting.

Background and aims: Smoking is associated with increased risk for brain aging/atrophy and dementia. Few studies have examined early associations with brain aging. This study aimed to measure whether adult men with a history of heavier smoking in early mid‐life would have older than predicted brain age 16–28 years later. Design Prospective cohort observational study, utilizing smoking pack years data from average age 40 (early mid‐life) predicting predicted brain age difference scores (PBAD) at average ages 56, 62 (later mid‐life) and 68 years (early old age). Early mid‐life alcohol use was also evaluated. Setting: Population‐based United States sample. Participants/cases: Participants were male twins of predominantly European ancestry who served in the United States military between 1965 and 1975. Structural magnetic resonance imaging (MRI) began at average age 56. Subsequent study waves included most baseline participants; attrition replacement subjects were added at later waves. Measurements Self‐reported smoking information was used to calculate pack years smoked at ages 40, 56, 62, and 68. MRIs were processed with the Brain‐Age Regression Analysis and Computation Utility software (BARACUS) program to create PBAD scores (chronological age—predicted brain age) acquired at average ages 56 (n = 493; 2002–08), 62 (n = 408; 2009–14) and 68 (n = 499; 2016–19). Findings In structural equation modeling, age 40 pack years predicted more advanced age 56 PBAD [β = −0.144, P = 0.012, 95% confidence interval (CI) = –0.257, −0.032]. Age 40 pack years did not additionally predict PBAD at later ages. Age 40 alcohol consumption, but not a smoking × alcohol interaction, predicted more advanced PBAD at age 56 (β = −0.166, P = 0.001, 95% CI = –0.261, –0.070) with additional influences at age 62 (β = −0.115, P = 0.005, 95% CI = –0.195, –0.036). Age 40 alcohol did not predict age 68 PBAD. Within‐twin‐pair analyses suggested some genetic mechanism partially underlying effects of alcohol, but not smoking, on PBAD. Conclusions: Heavier smoking and alcohol consumption by age 40 appears to predict advanced brain aging by age 56 in men. [ABSTRACT FROM AUTHOR]

Aims: To examine changes in drinking behavior among United States (US) adults between March 10 and July 21, 2020, a critical period during the COVID‐19 pandemic. Design Longitudinal, internet‐based panel survey. Setting: The Understanding America Study (UAS), a nationally representative panel of US adults age 18 or older. Participants: A total of 4298 US adults who reported alcohol use. Measurements Changes in number of reported drinking days from March 11, 2020 through July 21, 2020 in the overall sample and stratified by sex, age, race/ethnicity, household structure, poverty status, and census region. Findings Compared with March 11, the number of drinking days per week was significantly higher on April 1 by an average of 0.36 days (95% CI = 0.30, 0.43), on May 1 by an average of 0.55 days (95% CI = 0.47, 0.63), on June 1 by an average of 0.41 days (95% CI = 0.33, 0.49), and on July 1 by an average of 0.39 days (95% CI = 0.31, 0.48). Males, White participants, and older adults reported sustained increases in drinking days, whereas female participants and individuals living under the federal poverty line had attenuated drinking days in the latter part of the study period. Conclusions: Between March and mid‐July 2020, adults in the United States reported increases in the number of drinking days, with sustained increases observed among males, White participants, and older adults.

Background and Aims: Past research has found that young smokers are more likely to make quit attempts; however, there are conflicting findings regarding age and quit success. This study examined the degree to which smoker age is related to making quit attempts and quit success. Design Ten waves of the International Tobacco Control Policy Cohort survey (ITC‐4C) collected between 2002 and 2014, with nine wave‐to‐wave transitions with predictors at the first wave predicting quit attempts and success by the next wave. Setting: Canada, the United States, the United Kingdom and Australia. Participants: Data from 15 874 smokers categorized into four age groups at baseline (18–24, 25–39, 40–54 and 55+ years). Measurements Age, quit attempts and success (defined as ≥ 30 days abstinence confirmed, if possible, on a third wave for recent attempts). Findings Older smokers were more likely to smoke daily (χ2 = 1557.86, r = 0.136, P < 0.001) than younger smokers. Daily smokers were less likely to report quit attempts (38.1 versus 58.2%) and to achieve 30 days of abstinence (22.9 versus 34.3%) than non‐daily smokers. Older daily smokers were less likely to make quit attempts [0.61, confidence interval (CI) = 0.54–0.70, P < 0.001], even after controlling for indicators of nicotine dependence, country, sex, education, income, relationship status and household composition, than younger smokers. Younger smokers (< 25) were more likely to succeed for at least 30 days of abstinence, but only when compared with those aged 40–54 (OR = 0.83, 95% CI = 0.68–0.99). However, when controlling for heaviness of smoking the age effect disappeared. Significant interactions with age were found between age and intention when predicting quit attempts, and age and heaviness of smoking when predicting quit success. Conclusions: An international cohort study indicates that young smokers are more likely to attempt to quit and appear to have similar levels of success in abstaining from smoking compared with older smokers when controlling for dependence. Quit success in all ages is most predicted by lower levels of nicotine dependence. [ABSTRACT FROM AUTHOR]

Aims: To examine whether norms towards nicotine vaping product (NVP) use varied between Australia, Canada, England and the United States and by socio‐demographics, smoking and NVP status. Design Cross‐sectional data from the 2016 ITC Four Country Smoking and Vaping Survey. Setting: Four countries with distinct regulatory policies relating to the sale and advertising of NVPs: Australia (most restrictive), Canada (restrictive), England and the United States (least restrictive). Participants: A total of 10900 adult (age 18+) current smokers, former smokers, or at least weekly NVP users. Respondents were from Australia (n = 1366), Canada (n = 3309), England (n = 3835) and the United States (n = 2390). Measurements Questions permitted the categorization of respondents as current smokers, former smokers, NVP users and socio‐demographic categories (sex, age, country, ethnicity, income and education). Further questions were asked regarding the frequency of exposure to NVPs in public, whether they had a partner or close friends who vaped and whether they believed society or those considered important to them approved of NVPs. Findings Adjusting for relevant covariates, compared with Australian respondents, those in England, Canada and the United States were more likely to report frequent exposure to NVPs in public (83.1%, 57.3% and 48.3%, respectively, compared to 19.8% in Australia; P < 0.0001), having a partner who vaped (13.8%, 7.1% and 7.7%, respectively, compared to 2.1% in Australia; P < 0.0001) and having close friend(s) who vaped (31.7%, 25.3%, 20.9%, respectively, compared to 10.0% in Australia; P < 0.0001). Compared with Australian respondents, respondents from England were more likely to report that society (27.6% compared to 12.3% in Australia; P < 0.0001) and people important to them approved of NVP use (28.9% compared to 14.3% in Australia; P < 0.0001). Conclusions: Norms towards nicotine vaping product (NVP) use appear to vary among countries with different regulatory contexts regarding sales and advertising. [ABSTRACT FROM AUTHOR]

Aim: To describe the methods of the 2016 International Tobacco Control (ITC) Four Country Smoking and Vaping (4CV) Survey, conducted in 2016 in Australia (AU), Canada (CA), England (EN) and the United States (US). Methods: The respondents were cigarette smokers, former smokers (quit within the previous 2 years), and at‐least‐weekly vapers, aged 18 years and older. Eligible cohort members from the ITC Four Country Survey (4C) were retained. New respondents were sampled by commercial firms from their panels. Where possible, ages 18–24 and vapers were oversampled. Data were collected online, and respondents were remunerated. Survey weights were calibrated to benchmarks from nationally representative surveys. Results: Response rates by country for new recruits once invited ranged from 15.2 to 49.6%. Sample sizes for smokers/former smokers were 1504 in AU, 3006 in CA, 3773 in EN and 2239 in the US. Sample sizes for additional vapers were 727 in CA, 551 in EN and 494 in the US. Conclusion: The International Tobacco Control Four Country Smoking and Vaping Survey design and data collection methods allow analyses to examine prospectively the use of cigarettes and nicotine vaping products in jurisdictions with different regulatory policies. The effects on the sampling designs and response quality of recruiting the respondents from commercial panels are mitigated by the use of demographic and geographic quotas in sampling; by quality control measures; and by the construction of survey weights taking into account smoking/vaping status, sex, age, education and geography.

Background and Aims Including a low‐intensity blood collection method in population‐based alcohol studies would advance our ability to study biological mechanisms related to alcohol. However, the likelihood of participation in such a blood collection method remains understudied. This study's primary aims were to (1) estimate the return rate of mail‐in, self‐administered dried blood spot (saDBS) samples in national surveys and (2) test correlates of returning a sample. Design Re‐contact of all eligible participants from two telephone, population‐based alcohol surveys followed by χ2 tests and multivariate logistic regression analysis. Setting Non‐institutionalized US population in all 50 states and Washington, DC. Participants Adults aged 18+ who reported drinking at least one alcoholic beverage in the past 12 months (assessed 2017–18). Contact was made with 680 eligible participants, and 257 consented. Measurements The return rate of saDBS samples was defined as the proportion of returned samples among those who were eligible and contacted. Key correlates examined were gender, age, race/ethnicity and education. Findings Among the 680 eligible people contacted, 179 (26.3%) returned a saDBS sample. Blacks [odds ratio (OR) = 0.58, 95% confidence interval (CI) = 0.35–0.95], Latinos (OR = 0.40, 95% CI = 0.23–0.69) and those with a high school education or less (OR = 0.50, 95% CI = 0.31–0.81). Conclusions: The likelihood of participating in mail‐in, self‐administered dried blood spot (saDBS) sampling among drinkers in the US general population appears low, and blacks, Latinos and people with lower levels of education appear less likely to provide a saDBS sample compared with whites and people with higher levels of education.

Background and Aims: Long‐term frequent marijuana use is associated with significant negative outcomes, yet little is known about the longitudinal course of marijuana use among those who start frequent use during adolescence. Objectives are (a) to identify latent patterns of within‐person marijuana use from ages 19–30 years among 12th graders reporting frequent marijuana use, (b) to examine if membership in identified patterns has changed across historical time and (c) to examine if key covariates differentiate class membership. Design, Setting, Participants: Longitudinal, national US panel data from 4423 individuals [53.4% of the eligible sample; 2744 (62%) males] who reported frequent marijuana use in 12th grade (modal age 18 years; senior year cohorts 1976–2006) followed biennially from ages 19/20 to 29/30. Measurements Self‐reported past 30‐day marijuana use (frequent use defined as use on 20+ occasions), demographics, college graduation, marriage and parenthood. Findings Repeated‐measures latent class analysis (RMLCA) identified five latent classes of past 30‐day marijuana use from ages 19/20 to 29/30: continued frequent users (estimated membership 23.4%); frequent to non‐frequent users (15.5%); consistent non‐frequent users (18.4%); non‐frequent users to discontinuers (19.5%); and discontinuers (23.2%). In multivariable models, membership in the highest‐risk latent class (continued frequent users) versus one or more of the lower‐risk latent classes was more likely for recent cohorts (P = 0.038 to <0.001), as well as those who did not marry (P = 0.039 to < 0.001) or become parents (P = 0.001) by modal age 29/30. Conclusions: Nearly one in four 12th grade (modal age 18 years) frequent marijuana users in the US continues to report high frequency use to age 30; the proportion continuing high frequency use across young adulthood has increased among more recent cohorts.

Aims: Survey data from 10 diverse countries were used to analyse the social location of harms from others' drinking: which segments of the population are more likely to be adversely affected by such harm, and how does this differ between societies? Methods: General‐population surveys in Australia, Chile, India, Laos, New Zealand, Nigeria, Sri Lanka, Thailand, United States and Vietnam, with a primary focus on the social location of the harmed person by gender, age groups, rural/urban residence and drinking status. Harms from known drinkers were analysed separately from harms from strangers. Results: In all sites, risky or moderate drinkers were more likely than abstainers to report harm from the drinking of known drinkers, with risky drinkers the most likely to report harm. This was also generally true for harm from strangers' drinking, although the patterns were more mixed in Vietnam and Thailand. Harm from strangers' drinking was more often reported by males, while gender disparity in harm from known drinkers varied between sites. Younger adults were more likely to experience harm both from known drinkers and from strangers in some, but not all, societies. Only a few sites showed significant urban/rural differences, with disparities varying in direction. In multivariate analyses, most relationships remained, although some were no longer significant. Conclusion: The social location of harms from others' drinking, whether known or a stranger, varies considerably between societies. One near‐commonality among the societies is that those who are themselves risky drinkers are more likely to suffer harm from others' drinking. [ABSTRACT FROM AUTHOR]

Abstract: Aims: To assess (1) how far the efficacies of front‐line smoking cessation pharmacotherapies vary as a function of smoker characteristics and (2) associations between these characteristics and success of smoking cessation attempts. Design: Prospective correlational study in the context of a double‐blind randomized trial. The outcome was regressed individually onto each covariate after adjusting for treatment, and then a forward stepwise model constructed. Treatment moderator effects of covariates were tested by treatment × covariate interactions. Setting: Health service facilities in multiple countries. Participants: Data came from 8120 smokers willing to make a quit attempt, randomized to varenicline, bupropion, nicotine replacement therapy (NRT) or placebo in Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES) between 30 November 2011 and 13 January 2015. Measurements: Smoker characteristics measured at baseline were country, psychiatric history, sex, age, body mass index (BMI), ethnic group, life‐time suicidal ideation/behaviour, anxiety, depression, aggression, psychotropic medication, history of alcohol/substance use disorder, age of starting smoking, cigarette dependence [Fagerström Test for Cigarette Dependence (FTCD)] and prior use of study medicines. Outcome was biochemically confirmed continuous abstinence at weeks 9–24 from start of treatment. Findings: No statistically significant treatment × covariate interactions were found. Odds of success were associated independently positively with age [odds ratio (OR) = 1.01; 95% confidence interval (CI) = 1.00, 1.01], BMI (1.01; 95% CI = 1.00, 1.02) and age of starting smoking (1.03; 95% CI = 1.02, 1.04). Odds were associated independently negatively with US (versus non‐US) study site (0.53; 95% CI = 0.46, 0.61), black (versus white) ethnic group (0.57; 95% CI = 0.45, 0.72), mood disorder (0.85; 95% CI = 0.73, 0.99), anxiety disorder (0.71; 95% CI = 0.55, 0.90) and psychotic disorder (0.73; 95% CI = 0.50, 1.07), taking psychotropic medication (0.81; 95% CI = 0.68, 0.95), FTCD (0.89; 95% CI = 0.87, 0.92) and previous use of NRT (0.78; 95% CI = 0.67, 0.91). Conclusions: While a range of smoker characteristics—including psychiatric history, cigarette dependence and prior use of nicotine replacement therapy (NRT)—are associated with lower cessation rates, they do not substantially influence the efficacy of varenicline, bupropion or NRT.

Abstract: Aims: We evaluated the effects of a community organizing intervention, Communities Mobilizing for Change on Alcohol (CMCA), on the propensity of retail alcohol outlets to sell alcohol to young buyers without age identification and on alcohol acquisition behaviors of underage youth. Design: Random assignment of community to treatment (n = 3) or control (n = 2). Student surveys were conducted four times per year for 3 years; the cohort was in 9th and 10th grades in the 2012–13 academic year. Alcohol purchase attempts were conducted every 4 weeks at alcohol retailers in each community (31 repeated waves). Setting: The Cherokee Nation, located in northeastern Oklahoma, USA. Participants: A total of 1399 high school students (50% male; 45% American Indian) and 113 stores licensed to sell alcohol across five study communities. Intervention: Local community organizers formed independent citizen action teams to advance policies, procedures and practices of local institutions in ways to reduce youth access to alcohol and foster community norms opposed to teen drinking. Measurements: Perceptions regarding police enforcement and perceived difficulty of and self‐reported actual acquisition of alcohol from parents, adults, peers and stores. Findings: Alcohol purchases by young‐appearing buyers declined significantly, an 18 [95% confidence interval (CI) = 3, 33] percentage‐point reduction over the intervention period. Student survey results show statistically significant differences in the trajectory of perceived police enforcement, increasing 7 (4, 10) percentage points, alcohol acquisition from parents, decreasing 4 (0.1, 8) percentage points, acquisition from 21+ adults, decreasing 6 (0.04, 11) percentage points, from < 21 peers decreasing 8 (3, 13) percentage points and acquisition from stores decreasing 5 (1, 9) percentage points. Conclusions: A community organizing intervention, Communities Mobilizing for Change on Alcohol (CMCA), is effective in reducing the availability of alcohol to underage youth in the United states. Furthermore, results indicate that the previously reported significant effects of CMCA on teen drinking operate, at least in part, through effects on alcohol access. [ABSTRACT FROM AUTHOR]

Background and aims Prescription opioid overdose is a leading cause of injury-related morbidity and mortality in the United States. We aimed to identify characteristics associated with clinical severity in emergency department patients with prescription opioid overdose. Design This was a secondary data analysis of adult prescription opioid overdoses from a large prospective cohort of acute overdoses. We examined elements of a typical emergency department evaluation using a multivariable model to determine which characteristics were associated with clinical severity, specifically severe respiratory depression (SRD). Setting This study was conducted at two urban academic emergency departments in New York City, USA. Participants Adult patients who presented with acute prescription opioid overdose between 2009 and 2013 were included in the current study. We analyzed 307 patients (mean age = 44.7, 42% female, 2.0% mortality). Measurements Patient demographics, reported substances ingested, suspected intent for ingesting the substance, vital signs, laboratory data, treatments including antidotes and intubation and outcome of death were recorded by trained research assistants. Intent was categorized into four mutually exclusive categories: suicide, misuse, therapeutic error and undetermined. The primary outcome was SRD, defined as administration of either (a) naloxone or (b) endotracheal intubation (ETI). Findings A total of 109 patients suffered SRD with 90 patients receiving naloxone alone, nine ETI alone and 10 both naloxone and ETI. The most common opioids were oxycodone ( n = 124) and methadone ( n = 116). Mean age was higher in patients with SRD (51.1 versus 41.1, P < 0.001). Opioid misuse was associated with SRD in the multivariable analysis [odds ratio (OR) = 2.07, 95% confidence interval (CI) = 1.21-3.55]. The unadjusted relative risk of SRD was high for fentanyl (83.3% SRD) and lowest for codeine (3.6% SRD). Conclusion In emergency department patients in the United States with prescription opioid overdose, worse clinical severity was associated with opioid misuse, increased with age and was widely variable, depending on the specific opioid medication involved.

Aims To identify the developmental course of non-medical use of four separate prescription drug classes (opioids, sedatives, stimulants and tranquilizers) by examining the general functional growth and related covariates during the transition from adolescence to adulthood in the United States. Design Nationally representative probability samples of high school seniors were followed longitudinally across five waves (waves 1, 2, 3, 4 and 5: modal ages 18, 19/20, 21/22, 23/24 and 25/26 years, respectively). Setting Data were collected via self-administered questionnaires to high school seniors and young adults in the United States. Participants The sample consisted of nearly 72 000 individuals in 30 cohorts (high school senior years of 1977-2006) who participated in at least one wave. Measurements Self-reports of annual non-medical use of prescription opioids, sedatives, stimulants, and tranquilizers. Findings The annual non-medical use of prescription opioids, sedatives, stimulants and tranquilizers was highest at wave 1 over the five waves. There was a consistent descending path (linear and quadratic slopes, P < 0.001) in annual non-medical use from baseline across all four prescription drug classes (e.g. opioids linear slope = −0.043 and opioids quadratic slope = 0.034, P < 0.001). While the annual non-medical use of stimulants declined over time (linear slope = 0.063, P < 0.01; quadratic slope = −0.133, P < 0.001), the same decrease was not observed for the annual non-medical use of prescription opioids, sedatives or tranquilizers when controlling for socio-demographic and substance use behaviors at baseline. The covariates associated with the general functional growth differed across the four prescription drug classes. Conclusions The non-medical use of prescription opioids, sedatives, stimulants and tranquilizers appears to peak during late adolescence, suggesting preventive intervention efforts should be initiated in early adolescence. The developmental course of non-medical use is not the same among all four classes of prescription drugs, suggesting that each drug class warrants individual research. [ABSTRACT FROM AUTHOR]

Background and aims While mortality rates after prison release are high, little is known about clinical risk factors for death. We sought to identify risk and protective factors for all-cause and accidental poisoning (overdose) death. Design Nested case-control study of people released from prison. Setting Washington State Department of Corrections, Washington, USA. Participants Cases (699 all-cause deaths, of which 88 were among women, and 196 additional overdose deaths, of which 76 were among women) between 1999 and 2009 matched 1 : 1 to controls on sex, age and year of release using risk set sampling. Measurements Prison medical charts were abstracted for clinical information. Independent associations between clinical characteristics and all-cause and overdose mortality were assessed using conditional logistic regression. Findings Key independent risk factors for all-cause mortality included homelessness [odds ratio (OR) = 1.53, 95% confidence interval (CI) = 1.06, 2.23], injection drug use (OR = 1.54, 95% CI = 1.16, 2.06), tobacco use (OR = 1.51, 95% CI = 1.07, 2.13), cirrhosis (OR = 4.42, 95% CI = 1.63, 11.98) and psychiatric medications before release (OR = 2.38, 95% CI = 1.71, 3.30). Independent risk factors for overdose mortality included substance use disorder (OR = 2.33, 95% CI = 1.32, 4.11), injection drug use (OR = 2.43, 95% CI = 1.53, 3.86), panic disorder (OR = 3.87, 95% CI = 1.62, 9.21), psychiatric prescriptions before release (OR = 2.44, 95% CI = 1.55, 3.85) and problems with opiates/sedatives (OR = 2.81, 95% CI = 1.40, 5.63). Substance use disorder treatment during the index incarceration was protective for all-cause (OR = 0.67, 95% CI = 0.49, 0.91) and overdose (OR = 0.57, 95% CI = 0.36, 0.90) mortality. Conclusions Injection drug use and substance use disorders are risk factors for death after release from prison. In-prison substance use disorder treatment services may reduce the risk.

Aims To examine differences between early-onset versus later-onset pathological gamblers in socio-demographic characteristics, rates of Axis I and II disorders, preferred type of gambling and rates of treatment-seeking in a large nationally representative survey of adults in the United States. Design Data were collected from face-to-face interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM- IV version IV ( AUDADIS- IV). Setting and Measurement The study drew on data from the United States' National Epidemiologic Survey on Alcohol and Related Conditions ( NESARC). Participants All individuals with a DSM- IV diagnosis of pathological gambling ( PG). To be consistent with prior studies, age of onset of PG was dichotomized as 25 years and younger (early-onset) versus 26 years and older (later-onset). Findings Individuals with early-onset PG were more likely than individuals with later-onset PG to be male [odds ratio ( OR) = 2.86; 95% confidence interval ( CI) = 1.20, 6.82], never married ( OR = 3.51; 95% CI = 1.39, 8.84), to have income below US$70 000 ( OR = 0.09; 95% CI = 0.01, 0.61), to belong to younger cohorts ( OR = 0.93; 95% CI = 0.89, 0.97) and to have a cluster B personality disorder ( OR = 4.11; 95% CI = 1.77, 9.55), but less likely to have a mood disorder ( OR = 0.42; 95% CI = 0.19, 0.94). There were no differences between individuals with early- and later-onset PG regarding rates of treatment-seeking ( OR = 0.71; 95% CI = 0.20, 2.43) or preferred type of gambling ( OR = 2.00; 95% CI = 0.55, 7.3). All results remained significant after adjusting for age, sex and race, except the difference in the prevalence for mood disorders, which was no longer significant. Conclusions Individuals with early-onset versus later-onset pathological gambling differ in several socio-demographic and clinical characteristics, but not in their preferred types of game. Individuals from more recent cohorts appear to be at significantly increased risk for developing early-onset pathological gambling. [ABSTRACT FROM AUTHOR]

Aims To assess age variation in correlates of drinking cessation. Design Prospective study of a US general population sample. Setting Face-to-face household interviews. Participants Past-year ≥ monthly drinkers interviewed at baseline and 3-year follow-up ( n = 14 885). Measurements Baseline values and selected changes over follow-up in alcohol consumption, alcohol use disorder ( AUD), socio-demographic and health characteristics, other substance use and psychiatric comorbidity were used to predict drinking cessation in three age groups. Findings Correlates of drinking cessation varied over the life-course, with pregnancy/presence of an infant, nicotine or drug use disorder, incident AUD, cluster A personality disorder, liver disease and incident retirement being important at younger ages and high-school graduation, family income ≥ $70 000, volume of ethanol intake, Asian race/ethnicity, mood disorder and incident cardiovascular disease being significant at older ages. Age-invariant correlates included smoking cessation over follow-up, odds ratio ( OR) = 2.82 [95% confidence interval ( CI): 1.62-4.92] to 3.45 (2.20-5.39); college education, OR = 0.42 (0.27-0.65) to 0.54 (0.36-0.83); black and Hispanic race/ethnicity, OR = 1.74 (1.18-2.29) to 1.88 (1.21-2.93) and 1.58 (1.11-1.25) to 1.73 (0.83-3.63), respectively, and months since last drink, OR = 1.24 (1.13-1.36) to 1.29 (1.19-1.39). Conclusions Factors associated with ceasing alcohol use in US adults appear to differ over the life-course, reflecting age variation in both their prevalence and impact and supporting the importance of role transitions and health problems (the 'sick quitter' effect). The most consistent correlates of drinking cessation included factors reflecting ability/inability to give up potentially addictive substances and factors associated with perceived acceptability of drinking and subgroup-specific drinking contexts that might facilitate/impede continued drinking.

ABSTRACT Aims Marital dissolution is associated with increased risk of problematic drinking. However, marriage to a problem drinker also increases this risk, and ending this type of relationship may actually decrease risk of problematic drinking. This study tested whether women ending their marriage to a problem drinker exhibited improvements in drinking. Design National Epidemiologic Survey on Alcohol and Related Conditions, a two-wave nationally representative survey of the US adult population. Setting In-person interviews conducted in US households. Participants Females married or living as if married at wave 1 at least 18 years of age. Measurements Socio-demographics, drinking frequency, drinking quantity, alcohol use disorders, problem drinking, partner problem drinking and relationship dissolution. Findings Ending marriage to a non-problem drinker predicted increased frequency of drinking [risk ratio (RR) = 1.55; 95% confidence interval (CI) = 1.43, 1.67], heavier drinking (RR = 1.30; 95% CI = 1.71, 1.45), more problematic drinking (RR = 2.45; 95% CI = 2.17, 2.77) and a greater likelihood of use disorder diagnosis [odds ratio (OR) = 2.2; 95% CI = 1.67, 2.91]. Ending a relationship with a problem drinker predicted less frequent drinking (RR = 0.94; 95% CI = 0.90, 0.98), less heavy drinking (RR = 0.84; 95% CI = 0.78, 0.90) and fewer alcohol-related problems (RR = 0.77; 95% CI = 0.62, 0.95). Conclusions Ending a marriage with a husband who drinks problematically may decrease risk of alcohol-related problems among women, substantiating the need for alcohol treatments to address a problem drinking partner.

ABSTRACT Aims To estimate ethnic differences in three components of alcohol use disorder and alcohol dependence course (onset, persistence and recurrence) in a developmental framework. Design Longitudinal data from The National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), collected using face-to-face interviews. Setting Civilian non-institutionalized US population aged 18 years and older, with oversampling of Hispanics, blacks and those aged 18-24 years. Participants Individuals who completed both NESARC assessments, were not life-long abstainers and were either white ( n = 17 458), black ( n = 4995), US-born Hispanic ( n = 2810) or Hispanic-born outside the United States ( n = 2389). Measurements Alcohol dependence (AD) and alcohol use disorder (AUD; abuse or dependence) onset, persistence and recurrence were examined using the Alcohol Use Disorders and Associated Disabilities Interview Schedule, DSM-IV version. Findings Among men: relative to whites aged 18-29, AUD onset and persistence were elevated only in US-born Hispanics aged 40 years and older; odds were reduced for all non-US-born Hispanics, older whites, most blacks and US-born Hispanics aged 30-39. For AD, onset risk was elevated for all younger minority men and only reduced among non-US-born aged Hispanics 40 or older. For women: compared to young whites, non-US-born Hispanics were at decreased AUD and AD onset risk; AUD and AD onset and persistence were increased for older blacks and US-born Hispanics. Conclusions In the United States, ethnic differences in alcohol disorder transitions (onset, persistence, and recurrence) vary across age, gender and whether a broad (alcohol use disorder) or narrow (alcohol dependence) alcohol definition is used. Evidence of increased risk for some transitions in minority groups suggests that attention should be paid to the course of alcohol use disorders, and that differences in prevalence should not be assumed to reflect differences in specific transitions.

ABSTRACT Aims To investigate whether differences in gender-income equity at country level explain national differences in the links between alcohol use, and the combination of motherhood and paid labour. Design Cross-sectional data in 16 established market economies participating in the Gender, Alcohol and Culture: An International Study (GenACIS) study. Setting Population surveys. Participants A total of 12 454 mothers (aged 25-49 years). Measurements Alcohol use was assessed as the quantity per drinking day. Paid labour, having a partner, gender-income ratio at country level and the interaction between individual and country characteristics were regressed on alcohol consumed per drinking day using multi-level modelling. Findings Mothers with a partner who were in paid labour reported consuming more alcohol on drinking days than partnered housewives. In countries with high gender-income equity, mothers with a partner who were in paid labour drank less alcohol per occasion, while alcohol use was higher among working partnered mothers living in countries with lower income equity. Conclusion In countries which facilitate working mothers, daily alcohol use decreases as female social roles increase; in contrast, in countries where there are fewer incentives for mothers to remain in work, the protective effect of being a working mother (with partner) on alcohol use is weaker. These data suggest that a country's investment in measures to improve the compatibility of motherhood and paid labour may reduce women's alcohol use. [ABSTRACT FROM AUTHOR]

ABSTRACT Aims Studies of the relationship between social norms and marijuana use have generally focused on individual attitudes, leaving the influence of larger societal-level attitudes unknown. The present study investigated societal-level disapproval of marijuana use defined by birth cohort or by time-period. Design Combined analysis of nationally representative annual surveys of secondary school students in the United States conducted from 1976 to 2007 as part of the Monitoring the Future study. Setting In-school surveys completed by adolescents in the United States. Participants A total of 986 003 adolescents in grades 8, 10 and 12. Measurements Main predictors included the percentage of students who disapproved of marijuana in each birth cohort and time-period. Multi-level models with individuals clustered in time-periods of observation and birth cohorts were modeled, with past-year marijuana use as the outcome. Findings Results indicated a significant and strong effect of birth cohort disapproval of marijuana use in predicting individual risk of marijuana use, after controlling for individual-level disapproval, perceived norms towards marijuana and other characteristics. Compared to birth cohorts in which most (87-90.9%) adolescents disapproved of marijuana use, odds of marijuana use were 3.53 times higher in cohorts where fewer than half (42-46.9%) disapproved (99% confidence interval: 2.75, 4.53). Conclusions Individuals in birth cohorts that are more disapproving of marijuana use are less likely to use, independent of their personal attitudes towards marijuana use. Social norms and attitudes regarding marijuana use cluster in birth cohorts, and this clustering has a direct effect on marijuana use even after controlling for individual attitudes and perceptions of norms.

Adults and adolescents in the United States are experiencing unprecedented increases in depression and suicide, yet while marijuana and other drug use are increasing among adults,they are decreasing among adolescents. The causes and,therefore the remedies, of this public health burden may be fundamentally different between the two generations. [ABSTRACT FROM AUTHOR]

The author comments on a study by Kerr and colleagues which revealed that in the U.S. the 1976-1985 birth cohorts report higher alcohol consumption than that of previous and following ones. The study highlights regular increase in consumption of only wine, from the mid 1990's; and attributes this to French Paradox which states that a moderate intake of alcohol could be beneficial to health. She mentions that despite this there may be a trend towards binge drinking in the U.S.
