Parental alcohol misuse and hazardous drinking among offspring in a general teenage population: gender-specific findings from the Young-HUNT 3 study

Paternal and maternal psychological distress and adolescent health risk behaviors: The role of sensitive periods

INTRODUCTION

Adolescent health risk behaviors are linked to poor physical and mental health outcomes. While past research shows that maternal psychological distress predicts those behaviors, we know less about the role of paternal psychological distress and the role of sensitive periods.

METHODS

Using 11,128 data from families (50.5% female children) from the UK's Millennium Cohort Study, we examined the role of timing of exposure to paternal and maternal psychological distress in engagement in health risk behaviors (smoking, alcohol use, binge drinking, and sexual activity) at age 14. Paternal and maternal psychological distress, measured with the Kessler-6 scale, were assessed at child ages 3, 7, and 11. We performed path analysis, adjusting for key covariates, modeling maternal distress parallel to paternal, and allowing for autoregressive paths.

RESULTS

Paternal distress experienced at age 11 predicted a higher likelihood of smoking at age 14. Maternal distress at age 7 also predicted a higher likelihood of smoking, alcohol use, and binge drinking, but only for boys. Moreover, maternal distress at age 3 was associated with a lower risk for alcohol use. Effects were not replicated in the sensitivity analysis we performed, including only families with resident biological fathers across the study period. Instead, maternal and paternal distress at age 11 raised girls' risk for binge drinking and sexual activity, respectively.

CONCLUSIONS

Parental distress in early childhood does not predict adolescent health risk behaviors. In late childhood, however, both paternal and maternal distress seem to influence the likelihood of engagement in such behaviors.

Perceived parental alcohol problems and drinking patterns among adolescents in Sweden

Introduction

Much research into the links between parental problematic alcohol use and adolescent substance use has focused on clinically diagnosed parental alcohol disorders. Few prior studies have utilised validated measures of adolescents' perception of parental alcohol problems and considered the severity of these problems. This study examined the associations between the severity of perceived parental alcohol problems and adolescents' drinking patterns in a Swedish national sample.

Methods

We used survey information from grade 9 and 11 students (15-18 years) from 2021 (n = 9,227). Perceived parental alcohol problems were measured by the short version of The Children of Alcoholics Screening Test (CAST-6). The outcomes were: alcohol consumption during the past 12 months, frequent heavy episodic drinking (HED), and early alcohol debut (before age 14). Sociodemographic characteristics were adjusted for.

Results

Binary logistic regressions showed that the severity of perceived parental alcohol problems was associated with alcohol consumption during the past 12 months (low severity OR 1.53, p < 0.001; moderate severity OR 1.85, p < 0.001; high severity OR 2.52, p < 0.001), HED (low severity OR 1.16, n.s.; moderate severity OR 1.31, n.s.; high severity OR 1.64, p < 0.01), and early alcohol debut (low severity OR 1.57, p < 0.001; moderate severity OR 1.65, p < 0.001; high severity OR 2.20, p < 0.001).

Conclusions

Adolescents with perceived parental alcohol problems are more likely to have risky drinking patterns themselves, and the likelihood becomes higher with increased severity. Effective interventions for children whose parents have drinking problems are important, and should also take the severity of the parents' drinking problem into account.

Perceived parental alcohol problems and psychosomatic complaints among adolescents in Sweden

Introduction

For adolescents, parental problem drinking can be regarded as a chronic stressor, negatively affecting their health. There is limited knowledge and a relative lack of empirical evidence on this topic, especially in Sweden. The aim of the current study was to examine perceived parental alcohol problems and the links with psychosomatic complaints among adolescents in Sweden.

Methods

Data were obtained from the Swedish Council for Information on Alcohol and Other Drugs' national survey of 2021, collected amongst 9,032 students in grades 9 (∼15-16 years) and 11 (∼17-18 years). Perceived parental alcohol problems were measured by the Children of Alcoholics Screening Test (CAST-6) scale, using a cutoff at ≥ 3. Psychosomatic complaints were captured by a binary measure based on the frequency of headache, stomach ache, feeling depressed or down, difficulties to fall asleep, and sleeping poorly at night. Sociodemographic characteristics included gender, grade, parental education, and parental country of birth. Descriptive analyses with chi2 tests and binary logistic regression analyses were performed.

Results

Adolescents with perceived parental alcohol problems had higher odds of reporting psychosomatic complaints compared with adolescents without perceived parental drinking problems, even when adjusting for sociodemographic characteristics. Girls, grade 11 students, adolescent with at least one parent born in Sweden, and those without university-educated parents were more likely to report parental alcohol problems.

Conclusions

The findings highlight adolescents with perceived parental alcohol problems need support. The school, being an arena where adolescents spend much of their time, may play a vital role in this regard.

The association between maternal and paternal substance use and child substance use, internalizing and externalizing problems: a systematic review and meta-analysis

AIMS

There is substantial evidence showing an association between parental substance use and child substance use and/or mental health problems. Most research focuses upon maternal substance use, with the influence of paternal substance use often being overlooked. We aimed to investigate the differential effects of maternal and paternal substance use upon children aged 0-18 years.

METHODS

We used systematic review methods to identify observational studies examining the association between either maternal or paternal substance use and child substance use and/or mental health problems. The odds ratio (OR) effect measure was used, for ease of computation. We used a random-effects model with the inverse variance method to meta-analyse the findings from eligible studies.

RESULTS

We included 17 unique studies with a total of 47 374 child participants. Maternal and paternal substance use were both associated with increased odds of child any drug use [OR = 2.09; 95% confidence interval (CI) = 1.53, 2.86; n = 12 349 participants; three studies and OR = 2.86; 95% CI = 1.25, 6.54; n = 5692 participants; three studies, respectively], child alcohol problem use (OR = 2.16; 95% CI = 1.73, 2.71; n = 7339 participants; four studies and OR = 1.70; 95% CI = 1.36, 2.12; n = 14 219 participants; six studies), child externalizing problems (OR = 1.81; 95% CI = 1.01, 3.22; n = 1748 participants; three studies and OR = 1.60; 95% CI = 1.18, 2.17; n = 2508 participants; six studies) and child internalizing problems (OR = 1.60; 95% CI = 1.25, 2.06; n = 1748 participants; three studies and OR = 1.42; 95% CI = 1.12, 1.81; n = 2248 participants; five studies). Child any alcohol use was associated with maternal substance use only (OR = 2.26; 95% CI = 1.08, 4.70; n = 28 691 participants; five studies).

CONCLUSIONS

Both maternal and paternal substance use are associated with child substance use and mental health problems.

Qualitative exploration of perceived barriers of exclusive breastfeeding among pregnant teenagers in the Greater Accra Region of Ghana

BACKGROUND

The World Health Organization endorses exclusive breastfeeding for the first six months of every child's life since exclusive breastfeeding has the potential of saving thousands of infants' lives. The global exclusive breastfeeding rate among mothers is sub-optimal. This predisposes infants born to teenage mothers to all types of ailments. Therefore, this study explored the factors that inhibit the practice of exclusive breastfeeding as perceived by pregnant teenagers in the Greater Accra Region of Ghana which is an urban area.

METHODS

The study used techniques in qualitative descriptive exploration to collect data from 30 pregnant teenagers through focus group discussions. Six focus group discussions were conducted and each group was made up of five participants. Informed consent was obtained from participants who were 18 years and above as well as parents of participants below 18 years while informed assent was obtained from participants below 18 years after purposive sampling. Interviews were audiotaped, transcribed and data were analysed through content analysis.

RESULTS

Two major themes and eight sub themes emerged from the data after analysis. Personal related barriers (negative emotional feelings, irrational thinking, perceived health risks to the baby and perceived self-inefficacy) and social related barriers (provider-client interaction, disapproval of exclusive breastfeeding by close relatives, unfriendly workplace policies and social myths) were the perceived factors that discouraged exclusive breastfeeding among teenage mothers.

CONCLUSION

Health professionals should be trained to provide culturally sensitive care to teenage mothers in order to promote exclusive breastfeeding. The media, religious leaders and politicians should help debunk misconceptions about breastfeeding expressed by participants in the study.

Problematic alcohol use in Mexican students: Transmission from parents to children

Introduction. Studies in various countries have shown that adolescents with a history of parental use of alcohol have a greater risk of presenting alcohol problems of their own, including binge drinking, driving under the influence of alcohol, and alcohol dependence. A few studies in Mexico have also found this association, but these have been carried out with non-representative populations. Objective. To examine the association between a history of parental alcohol use and binge drinking, and parental use and possible dependence on alcohol, in a national sample of junior high and high school students in Mexico. Method. A descriptive correlational study was carried out based on a secondary analysis of the National Survey of Student Drug Use (Encuesta Nacional de Consumo de Drogas en Estudiantes, ENCODE), which questioned 114,364 respondents. The association was evaluated with an estimate of prevalence ratios (PR). Results. Students whose mothers or both parents used alcohol had a greater risk for binge drinking (PR [mother] = 2.12, p #abr# .001; PR [both parents] = 2.18, p #abr# .001) and possible alcohol dependence (PR [mother] = 5.43, p #abr# .001; PR [both parents] = 5.14, p #abr# .001). Those whose fathers alone used alcohol had a lower risk for binge drinking (PR = 1.35, p #abr# .001) and for possible dependence (PR = 1.83, p #abr# .001). Discussion and conclusion. This study shows differences in the effects of problematic alcohol use by parents: use by the mother or by both parents implies a greater risk of binge drinking and possible dependence for their children. This finding should be considered in the design of interventions to prevent binge drinking.

Prevalence of Parental Alcohol Problems among a General Population Sample of 28,047 Norwegian Adults: Evidence for a Socioeconomic Gradient

The aim of the study presented here was to estimate the prevalence of parental alcohol problems during childhood in a general population of Norwegian adults, and to investigate associations between parental alcohol problems during childhood and lower socioeconomic status in adulthood. This cross-sectional study recruited 28,047 adults (≥18 years) to an online health survey (Norwegian Counties Public Health Surveys). We evaluated demographic and socioeconomic measures and responses to a shortened version of the Children of Alcoholics Screening Test (CAST-6) scale to assess whether respondents perceived parental alcohol consumption during childhood as problematic. Respondents reported parental alcohol problems at a rate of 15.6%, but the experience was more prevalent among adults with a low education (20.0%), compared to those with intermediate (16.4%) or high educations (13.8%, χ2(2) = 87.486, p < 0.001), and it was more common among respondents with low economic capabilities (21.1%) compared to those with middle/high capabilities (14.2%, χ2(1) = 162.089, p < 0.001). Parental alcohol problems were most prevalent among respondents that received welfare benefits (24.5%). Multivariable logistic regression analyses revealed associations between parental alcohol problems and low socioeconomic status in adulthood; odds ratios (95% confidence intervals) ranged from 1.33 (1.25-1.42) to 1.89 (1.72-2.06). From a public health perspective, children who grow up with parental alcohol problems should be reached through both universal and selective interventions.

Parental risk constellations and future alcohol use disorder (AUD) in offspring: A combined HUNT survey and health registries study

OBJECTIVE

We examined the risk of developing a future alcohol use disorder (AUD) among offspring of families with different constellations of parental risk factors.

METHOD

We analyzed a sample of 8,774 offspring (50.2% male) from 6,696 two-parent families who participated in the Nord-Trøndelag Health Study in Norway when offspring were 13-19 years old in 1995-1997 or 2006-2008. Based on population registry information and parental Nord-Trøndelag Health Study self-reports, families were classified via Latent Profile Analysis into fiver risk constellations reflecting parents' education, drinking quantities and frequencies, and mental health. Information about AUD-related diagnoses, treatments, and prescriptions for all offspring in the period between 2008 and 2016 was obtained from 3 national health registries and pooled to reflect any AUD. The likelihood of AUD in offspring was examined with a set of nested logistic regression models.

RESULTS

Registry records yielded 186 AUD cases (2.1%). Compared with the lowest-risk constellation, offspring from two constellations were more likely to present with AUD in unadjusted analyses. After adjusting for all covariates, including offspring's alcohol consumption and witnessing parental intoxication during adolescence, AUD risk remained elevated and statistically significant (adjusted odds ratio = 2.34, 95% confidence interval = 1.14, 4.85) for offspring from the constellation characterized by at least weekly binge drinking, low education, and poor mental health in both parents.

CONCLUSION

Weekly binge drinking by both parents was associated with future AUD risk among community offspring in Norway when clustered with additional parental risks such as poor mental health and low educational attainment. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Parental alcohol intoxication and adverse health outcomes among offspring. A 4-year follow up HUNT study among 2399 Norwegian adolescents

This study aimed to investigate whether experience of parental alcohol intoxication was associated with adverse health outcomes among adolescents four years later. A population-based Norwegian cohort study of 2399 adolescents who participated in the Young-HUNT1 Survey 1995-97 (T1, 13-15 years old) was followed up four years later (T2) in 2000 (Young-HUNT2, 17-19 years old). Measures were based on adolescent self-report of exposure to parental alcohol intoxication, self-rated general health, mental distress (SCL-5) and lifetime hospital admission. Multivariable logistic regression analyses, adjusted for gender, age and parental education were applied. Results show that half of the adolescents (51%) had seen parents intoxicated at age 13-15 years. Four years later, those who had reported parental alcohol intoxication at T1 had increased odds of admission to hospital with odds ratios ranging from OR1.3; CI 1.0-1.7 to OR 2.2; CI 1.3-3.9, poorer self-rated health (odds ratio ranging from 1.8;1.2-2.6 to 2.0;1.1-3.7) and more mental distress (odds ratio ranging from 1.7;1.1-2.5 to 1.9;1.0-3.6). Furthermore, the increased frequency of experience of parental alcohol intoxication are associated with higher prevalence of admission to hospital and mental distress and lower levels of self-rated health. Findings from this large, representative population of Norwegian adolescents indicate that adverse health outcomes among adolescents in a general population are related to relatively common heavy drinking behaviours among parents.

The Association Between Adverse Child Health, Psychological, Educational and Social Outcomes, and Nondependent Parental Substance: A Rapid Evidence Assessment

BACKGROUND

Between 5% and 30% of children in high-income countries live with a substance misusing parent, the majority of which is below dependent levels. However, little is understood about the impact of nondependent parental substance misuse upon children.

METHODS

We searched the international literature using rigorous systematic methods to identify studies examining parental substance misuse and adverse outcomes in children. The inclusion criteria were cross-sectional, longitudinal, case-control, and cohort studies; of children aged 0-18 years whose parents are high-risk substance misusers; reporting on their health, psychological, substance use, educational, and social outcomes.

RESULTS

We identified 36 papers (from 33 unique studies), most of which were assessed as being of medium to high methodological quality (N= 28). Parental nondependent substance misuse was found to be associated with adversity in children, with strong evidence of an association with externalizing difficulties (N = 7 papers, all finding an association) and substance use (N = 23 papers, all finding an association) in adolescents and some evidence of adverse health outcomes in early childhood (N = 6/8 papers finding an association). There is less evidence of an association between parental substance misuse and adverse educational and social outcomes. The body of evidence was largest for parental alcohol misuse, with research examining the impact of parental illicit drug use being limited.

CONCLUSION

Methodological limitations restrict our ability to make causal inference. Nonetheless, the prevalence of adverse outcomes in children whose parents are nondependent substance misusers highlights the need for practitioners to intervene with this population before a parent has developed substance dependency.

The number of biological parents with alcohol use disorder histories and risk to offspring through age 30

OBJECTIVE

We investigated associations between the number of parents with histories of alcohol use disorder (AUD) and several offspring (proband) variables through age 30: occurrence of AUD and, separately, alcohol dependence; onset age of the initial AUD episode; time to recovery from the first AUD episode; number of distinct AUD episodes; and cumulative duration of AUD across episodes.

METHODS

Offspring data were collected during four assessment waves of a longitudinal epidemiological study of psychiatric disorders with a regionally representative sample. The reference sample included 730 offspring with diagnostic data from at least one parent. Offspring were assessed with semi-structured diagnostic interviews between mid-adolescence and young adulthood and parents were assessed when offspring were approximately 24 years of age.

RESULTS

As the number of parents with AUD increased, offspring risk for AUD and alcohol dependence also increased. Latent growth model results indicated that offspring AUD risk trajectories increase in severity as a function of the number of parents with AUD. This pattern of results was not observed for other AUD course-related features in offspring (i.e., number of distinct episodes; months required for recovery from initial episode; cumulative duration across episodes).

CONCLUSIONS

The number of parents with a history of AUD is associated with overall offspring risk for AUD and alcohol dependence and elevated AUD risk trajectories through age 30. The number of parents with AUD may be a more relevant risk factor for onset-related characteristics of AUD in offspring than for its longitudinal course.

Prevalence of alcohol consumption and its risk factors among university students: A cross-sectional study across six universities in Myanmar

BACKGROUND

Globally, alcohol consumption is a significant public health concern and it is one of the most important risk behaviours among university students. Alcohol consumption can lead to poor academic performance, injuries, fights, use of other substances, and risky sexual behaviours among students. However, the study explored the prevalence of alcohol consumption and the associated risk factors among university students since these have not been fully examined in previous research. Therefore, the aim of this study was to explore the prevalence of alcohol consumption and the associated risk factors among university students in Myanmar.

METHODS

The present cross-sectional study was conducted using a sample of 15-24-year-old university students who were selected from six universities in Mandalay, Myanmar, in August 2018. In total, 3,456 students (males: 1,301 and females: 2,155) were recruited and asked to respond to a self-administered questionnaire. Multiple logistic regression analysis was used to estimate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for alcohol consumption among university students.

RESULTS

The prevalence of alcohol consumption in the previous 30 days was 20.3% (males: 36.0%, females: 10.8%). The alcohol consumption was significantly higher among males (AOR = 2.3, 95% CI; 1.9-2.9), truant students (AOR = 2.1, 95% CI; 1.3-3.3), smokers (AOR = 7.0, 95% CI; 5.1-9.7), students who reported feeling of hopelessness or sadness (AOR = 1.4, 95% CI; 1.2-1.8), peers' alcohol consumption (AOR = 7.5, 95% CI; 4.8-11.7).

CONCLUSION

The present study revealed that males, smokers, peer alcohol consumption, and truant students had higher odds of alcohol consumption among the students. Therefore, effective campus-based counselling, peer education, and national surveillance systems that can monitor risky drinking behaviours among university students should be implemented. Further, government regulations that control the production, sale, promotion, advertising, and restriction of alcohol should be well developed and strengthened, as in the case of other Southeast Asian countries.

Determinants of harmful use of alcohol among urban slum dwelling adults in Kenya

BACKGROUND

Harmful alcohol use is a public health problem associated with negative health and socio-economic impacts. However, patterns and dynamics of alcohol use among slum-dwellers in Kenya are poorly understood.

OBJECTIVE

To establish determinants of harmful alcohol use among adults in an urban slum setting in Kenya.

MATERIALS AND METHODS

Cross-sectional study involving a consecutively selected sample (N=215) from Githurai, in Nairobi. A pre-tested questionnaire that captured data on socio-demographics, drinking patterns, type, reasons, initiator, and support system.

RESULTS

Of the respondents, those above 31 years, married, separated/divorced/widowed, of high education, earning above 50 USD, and from dysfunctional families consumed more alcohol. Low earners consumed (p < 0.05) unrecorded while high earners drank (p< 0.001) recorded alcohol. Adults from families with a drinking father and sibling consumed more alcohol (p=0.001). Single, low educational attainment/earners, and those in dysfunctional families (p <0.05) drank due to stress and reported alcohol-related problems. Young, unmarried, and casual laborers were introduced (p < 0.05) to alcohol by friends.

CONCLUSION

Socio-demographic, economic, familial, social interactions, and stress are associated with harmful alcohol use among adults from slums calling for interventions targeting these factors.

Association of Constellations of Parental Risk With Children's Subsequent Anxiety and Depression: Findings From a HUNT Survey and Health Registry Study

IMPORTANCE

The research focus on children of parents with alcohol use disorder has eclipsed the potentially wider-reaching detrimental effects of subclinical parental drinking, both alone and in combination with other parental risk factors.

OBJECTIVE

To identify constellations of early parental risk characterized by variations in drinking, mental health, and education in both parents and examine their prospective associations with children's contact with the health care system for anxiety and/or depression (ie, diagnoses or treatment).

DESIGN, SETTING, AND PARTICIPANTS

This prospective study was based on linked survey and health registries data. The sample included 8773 children from 6696 two-parent families in Norway who participated in the Nord-Trøndelag Health Study (HUNT) survey in 1995 to 1997 or 2006 to 2008, when the children were aged 13 to 19 years. Data were analyzed from January to September 2018.

EXPOSURES

Five constellations of early parental risks, characterized by variations in drinking frequencies and amounts, mental health, and education for both parents, as identified through latent profile analysis.

MAIN OUTCOMES AND MEASURES

Children's diagnoses or treatment of anxiety and/or depression from 2008 to 2016 were recorded in 3 health registries. The primary outcome was the total number of registries where participants presented (ranging from 0 to 3).

RESULTS

Of the 8773 included children, 4404 (50.2%) were boys, and the mean (SD) age at the time of participation in the Nord-Trøndelag Health Study was 16.1 (1.8) years. Prevalence of anxiety and/or depression, as evidenced in at least 1 registry record, was 24.3% (2132 of 8773). Early parental risk profiles risks marked by (1) the lowest parental education (adjusted relative risk, 1.13; 95% CI, 1.01-1.25) and (2) elevated drinking in both parents and elevated mental health symptoms in fathers (adjusted relative risk, 1.52; 95% CI, 1.03-2.22) were associated with a significant increase in risk of anxiety and/or depression in children from those families compared with children from no-risk families.

CONCLUSIONS AND RELEVANCE

Studies seeking to understand prospective associations of parental drinking with children's mental health need to consider additional risk factors in combination with one another as well as parental behaviors and characteristics below clinically defined levels. When accumulated at a family level, even seemingly innocuous characteristics contributed to meaningful increases in risk of anxiety and/or depression among children, potentially translating into poorer mental health outcomes for many young people.

Gender Difference in Offspring's Alcohol Use Disorder by 21 Years: A Longitudinal Study of Maternal Influences

AIMS

There is little known about the extent to which maternal alcohol consumption influences offspring's alcohol use disorder. This study aims to examine whether different maternal alcohol consumption trajectories predict gender difference in adolescent alcohol use disorder at child age 21 years.

METHODS

Data are from a prospective cohort, the Mater-University of Queensland Study of Pregnancy (MUSP) and its outcomes. The study involves 2531 mother-child pairs for whom data are available at the 21-year follow-up survey. Maternal alcohol consumption trajectories were determined by group-based trajectory modelling. Offspring's lifetime ever alcohol use disorder was assessed using DSM-IV diagnostic criteria.

RESULTS

Over 14 years of follow-up after the birth of a child, three distinct alcohol consumption trajectories were identified (abstainer, low-stable. and moderate-escalating drinker). A maternal trajectory of moderate-escalating alcohol consumption independently predicted offspring's lifetime ever alcohol use disorder at 21 years after adjustment for a range of potential confounders. "Cross-gender influence" is observed in the study.

CONCLUSIONS

A maternal life course pattern of alcohol consumption may have an independent effect on offspring alcohol consumption, with male offspring being more vulnerable to the effects of maternal alcohol use than are female offspring. Programs intended to address alcohol consumption by adolescents and young adults need to focus on the behaviors of both parents but acknowledging that maternal patterns of alcohol consumption may be particularly important for male offspring.

Maternal Problem Drinking and Child Mental Health

BACKGROUND

Offspring of individuals with alcohol use disorders have been shown to have elevated risk for mental health problems.

OBJECTIVES

To examine the association between maternal problem drinking and child mental health as assessed by three informants in three European countries.

METHODS

Data were drawn from the School Child Mental Health in Europe study. Maternal alcohol use was assessed using the alcohol use disorders identification test. Child mental health was assessed using the mother and teacher versions of the strengths and difficulties questionnaire, and the child self-reported Dominic interactive. Analyses were performed on 2,678 individuals, 6-11 year olds.

RESULTS

Adjusting for variables associated with maternal drinking, among children eight years old or younger, excessive drinking was not significantly associated with mental health problems, whether reported by the mother, teacher or by the child. However, among girls eight years old and above, problem drinking was associated with conduct problems as reported by the mother (OR = 4.19), teacher reported total difficulties (OR = 4.69), and peer relationship problems (OR = 8.86). It was also associated with the presence of any child-reported disorder (OR = 3.88), externalizing (OR = 5.55) and internalizing disorders (OR = 4.42). Conclusions/Importance: Adjusting for sociodemographic variables and for psychological distress, maternal problem drinking was not significantly associated with child mental health problems in boys or in girls ages six to eight. The association was only present among girls ages 8-11. Examining relationships between mothers and their daughters in the peripubertal period may be a critical window for the development of effective intervention strategies.

Perceived parental alcohol problems and drinking patterns in youth: A cross-sectional study of 69,030 secondary education students in Denmark

The aim of the study was to examine whether young people with parental alcohol problems have different drinking patterns than those without parental alcohol problems. Further, we examined whether the association between parental alcohol problems and young people's drinking patterns differed depending on the gender of the child and the parent, and whether more severe parental alcohol problems and cohabitation with the parent with alcohol problems was associated with earlier and heavier drinking patterns. Data came from the Danish National Youth Study 2014, a web-based national survey. 75,025 high school and vocational school students (15-25years) participated. Drinking patterns were investigated by the following outcomes: non-drinking, weekly alcohol consumption, frequent binge drinking, and early intoxication debut age. The main predictor variables were perceived parental alcohol problems, gender of the parent with alcohol problems, cohabitation with a parent with alcohol problems and severity of the parents' alcohol problems. Young people with parental alcohol problems had a higher weekly alcohol consumption (boys: 15.2 vs. 13.9 drinks per week; girls: 11.6 vs. 10.2 drinks per week), higher odds of early intoxication debut age (boys: OR=1.68 [95% CI 1.50-1.89]; girls: OR 1.95 [95% CI 1.79-2.14]), and more frequent binge drinking (boys, OR=1.16 [95% CI 1.04-1.29]; girls, OR=1.21 [95% CI 1.11-1.32]) compared to young people without parental alcohol problems. In conclusion, this study shows that young people with perceived parental alcohol problems have an earlier intoxication debut age, binge drink more frequently, and drink larger quantities per week than young people without perceived parental alcohol problems.

Alcohol use among Norwegian students: Demographics, personality and psychological health correlates of drinking patterns

AIMS

This study investigates demographic, personality, and psychological health correlates of different drinking patterns.

DESIGN

Students at the four largest institutions of higher education in Bergen municipality were invited via email to complete an internet-based questionnaire. The final sample size was 11,236 (39.4%), mean age 24.9 years (SD = 6.5), and 63.3% were women. The survey included the Alcohol Use Disorder Identification Test (AUDIT) and questions about demographics, personality traits, and symptoms of depression and anxiety. Binary logistic regressions were used to identify correlates of different drinking patterns.

RESULTS

A total of 53.0% of the students had an AUDIT score of or above 8 (i.e., hazardous drinking). Being native Norwegian, male, single, without children, non-religious, extroverted, unconscientious, and less open to experience were associated with higher AUDIT scores, drinking frequently, and binge drinking. Having parents with high alcohol or drug use increased the odds of engaging in binge drinking, but this factor was not associated with frequent drinking. Students scoring higher on neuroticism and openness were less likely to report problematic alcohol usage.

CONCLUSIONS

A majority of the students reported alcohol habits that are associated with harm if they persist. This emphasises the need to examine the long-term consequences of students' alcohol use.

Gender differences in the prospective association between maternal alcohol consumption trajectories and young adult offspring's problem gambling at 30 years

Although a large number of studies have examined the association between young adult’s alcohol consumption and their problem gambling behaviours, none of these studies address the prospective association between mother’s alcohol consumption and their young adult offspring’s problem gambling behaviours. Using data from a 30 year prospective pre-birth cohort study in Brisbane, Australia (n = 1691), our study examines whether different maternal alcohol consumption trajectories predict offspring’s risk of problem gambling behaviours and whether these associations differ by the young adults’ gender. Offspring’s level of problem gambling behaviours was assessed by the short version of the Canadian Problem Gambling Index, with about 10.6 % of young adults having some risk of problem gambling behaviours. Trajectories of maternal alcohol consumption were determined by group-based trajectory modelling over five time points. Our study found that mother’s alcohol consumption pattern fits into three drinking trajectory groups, namely abstainers (17.2 %), a low-stable drinkers group (64.6 %) and a moderate-escalating drinkers group (18.2 %). Multivariate logistic regression analyses showed that the moderate-escalating alcohol trajectory group is independently associated with a risk of their male young adult offspring having problem gambling behaviours at 30 years—even after adjustment for a range of potential confounding variables. Mothers who exhibit a persistent life course pattern of moderate-escalating drinking have male children who have a high risk of engaging in problem gambling behaviours. Offspring’s alcohol consumption partially mediated the association between maternal drinking trajectories and young adult’s risk of problem behaviours. High levels of maternal alcohol consumption may lead to male offspring antisocial behaviours. Programs intended to address problem gambling behaviours by young adults may need to focus on male group with a focus which specifically addresses family influences as these contribute to gambling behaviour.

A Cohort Study on Long-Term Adverse Effects of Parental Drinking: Background and Study Design

Although many studies have addressed adverse outcomes in children of parents with alcohol abuse/dependence, less is known about the possible long-term effects of more normative patterns of parental alcohol consumption, including drinking at lower risk levels and heavy episodic or binge drinking. The extent of harm from parental drinking may therefore be underestimated. With this research proposal, we describe a project that aims to assess possible long-term adverse effects of parental drinking by combining survey and nationwide registry data. Advantages of a longitudinal general population cohort design include that it allows for detailed information on parental drinking through survey data and identification of possible negative long-term health and social outcomes from exposure to parental drinking 1-19 years after exposure through continuously updated nationwide registers. The rich information available from combining survey and registry data allows us to take into account important confounders, mediators, and moderators.

Identifying binge drinkers based on parenting dimensions and alcohol-specific parenting practices: building classifiers on adolescent-parent paired data

BACKGROUND

Most Dutch adolescents aged 16 to 18 engage in binge drinking. Previous studies have investigated how parenting dimensions and alcohol-specific parenting practices are related to adolescent alcohol consumption. Mixed results have been obtained on both dimensions and practices, highlighting the complexity of untangling alcohol-related factors. The aim of this study was to investigate (1) whether parents' reports of parenting dimensions and alcohol-specific parenting practices, adolescents' perceptions of these dimensions and practices, or a combination are most informative to identify binge drinkers, and (2) which of these parenting dimensions and alcohol-specific parenting practices are most informative to identify binge drinkers.

METHODS

Survey data of 499 adolescent-parent dyads were collected. The computational technique of data mining was used to allow for a data driven exploration of nonlinear relationships. Specifically, a binary classification task, using an alternating decision tree, was conducted and measures regarding the performance of the classifiers are reported after a 10-fold cross-validation.

RESULTS

Depending on the parenting dimension or practice, parents' reports correctly identified the drinking behaviour of 55.8% (using psychological control) up to 70.2% (using rules) of adolescents. Adolescents' perceptions were best at identifying binge drinkers whereas parents' perceptions were best at identifying non-binge drinkers.

CONCLUSIONS

Of the parenting dimensions and practices, rules are particularly informative in understanding drinking behaviour. Adolescents' perceptions and parents' reports are complementary as they can help identifying binge drinkers and non-binge drinkers respectively, indicating that surveying specific aspects of adolescent-parent dynamics can improve our understanding of complex addictive behaviours.

Posttraumatic stress avoidance symptoms as mediators in the development of alcohol use disorders after exposure to childhood sexual abuse in a Swiss community sample

This study examined the role of posttraumatic stress disorder (PTSD) symptoms of re-experience, avoidance, and hyperarousal in the relationship between different types of trauma and alcohol use disorders (AUD). We used data from 731 trauma-exposed individuals who participated in the first wave of the PsyCoLaus-study. Trauma characteristics were assessed relatively to the occurrence of lifetime PTSD symptoms and AUD. The results suggest that lifetime and childhood sexual abuse as well as overall childhood trauma were directly linked to AUD and PTSD symptoms, in particular to avoidance symptoms. From single symptom clusters PTSD avoidance was found to specifically mediate the trauma-AUD pathway. Both childhood and sexual trauma strongly contribute to the comorbidity of PTSD and AUD and avoidance-type symptoms appear to play a central role in maintaining this association. Hence, the alleviation of avoidance symptoms might be an important target for therapeutic intervention among victims of sexual abuse before specific addiction treatment is initiated.

Do parents play different roles in drinking behaviours of male and female adolescents? A longitudinal follow-up study

OBJECTIVE

Gender differences in the associations between adolescent drinking behaviour, and perceived parental drinking behaviours and attitudes towards underage drinking, were investigated.

METHODS

Data were drawn from two cohorts in the Child and Adolescent Behaviours in Long-term Evolution project. We used data from 2009 to 2006, when cohorts 1 and 2, respectively, were in grade 9. No cohort effect was found, so the two cohorts were pooled; 3972 students (1999 boys and 1973 girls) participated in the study. The major variables included adolescent drinking behaviours over the last month, and perceived parental drinking behaviours and parental attitudes towards underage drinking. The effects of the combination of parental drinking behaviours, and attitudes on the drinking behaviours of male and female adolescents, were analysed by logistic regression.

RESULTS

The drinking behaviour of boys was correlated with the drinking behaviours and attitudes of their fathers but not with those of their mothers. Among boys, having a non-drinking father who was against underage drinking (OR=0.27, 95% CI 0.16 to 0.46), a non-drinking father who was favourable towards underage drinking (OR=0.61, 95% CI 0.39 to 0.94), or a drinking father who was against underage drinking (OR=0.44, 95% CI 0.23 to 0.85) significantly decreased the likelihood of alcohol consumption, whereas maternal behaviour and attitude were not significant influences. Among girls, having a non-drinking father who was against underage drinking (OR=0.52, 95% CI 0.30 to 0.91) or a non-drinking father who was favourable towards underage drinking (OR=0.51, 95% CI 0.32 to 0.83) significantly decreased the likelihood of alcohol consumption, as did having a non-drinking mother who was against underage drinking (OR=0.23, 95% CI 0.09 to 0.60).

CONCLUSIONS

The influences of fathers and mothers on the drinking behaviour of their adolescent children differed by offspring gender.

The association between parental and adolescent substance misuse: findings from the Irish CASE study

Background

Self-report data from 2716 adolescents aged 15–17 years old in Irish schools were analysed to consider the association between psycho-social factors and the presence of adolescent substance and alcohol abuse, with an emphasis on family circumstances.

Methods

Data were collected using the ‘Lifestyle and Coping Questionnaire’ which includes questions about lifestyle, coping, problems, alcohol and drug use, deliberate self-harm, depression, anxiety, impulsivity and self-esteem. Two additional questions were added to the standard questionnaire regarding parental substance misuse.

Results

Adolescent substance abuse was more common in boys; parental substance misuse increased the risk of adolescent abuse of alcohol and drugs; the increased risk was marginally higher if the parental substance abuse was maternal rather than paternal; the increased risk was higher if the parental substance abuse affected both rather than one of the parents, especially regarding adolescent drug abuse; the magnitude of the increased risk was similar for boys and girls. Parental substance misuse increased the risk of adolescent substance abuse even after adjusting for other family problems and the adolescent’s psychological characteristics.

Conclusions

This study indicates that parental substance misuse affects the development of both alcohol and drug misuse in adolescent children independent of other family problems and the psychological characteristics of the adolescent. A wider perspective is needed, including societal and family issues, especially parental behaviour, when attempting to reduce risk of adolescent addiction. The impact on children of parental substance misuse also needs consideration in clinical contexts.

Intergenerational Hazardous Alcohol Use and Area Factors: The HUNT Study, Norway

BACKGROUND

Alcohol use among adolescents has been found to be associated with parental alcohol abuse, but it's relation to more prevalent forms of hazardous drinking patterns among parents has been less explored. Few studies have included area factors when investigating alcohol use across generations.

OBJECTIVES

The aims of this study were to investigate whether adolescent intoxication was associated with parental heavy episodic drinking (HED) and intoxication, area-level socioeconomic status (SES), and rates of area-level HED.

METHODS

General Estimation Equations (GEE) was applied to analyze data from the Nord-Trøndelag Health Study (2006-08) including 2,306 adolescents. Adolescent alcohol use was defined by self-reported frequency of intoxication. Parental alcohol use was defined by parental self-reports of drinking five glasses of alcohol at one occasion (HED), whether they had been strongly intoxicated, and adolescent reports of seeing parents intoxicated. Area-level SES and HED were based on data from HUNT3 and Statistics Norway.

RESULTS

Parental and offspring alcohol use were associated, although this varied to some extent with gender and exposures. The strongest associations were found between offspring intoxication and offspring reports of seeing their parent intoxicated (girls: OR 3.3, 95% CI 2.3-4.7; boys: OR 3.4, 95% CI 2.4-4.7). Intoxication was more common among girls, who lived in areas with a higher level of adult HED. Living in areas with higher SES was associated with less intoxication among adolescents.

CONCLUSION

Intoxication in adolescence was associated with factors at both family and area level, which emphasize the need of both population and high risk preventive approaches.
