The co-occurrence of mental disorders among Dutch adolescents admitted for acute alcohol intoxication.

Adolescents with substance use disorders are often diagnosed with co-occurring mental disorders. However, it is unknown if adolescent hospital admission for acute alcohol intoxication is also associated with co-occurring mental disorders. Therefore, the primary aim of this study is to estimate the prevalence of co-occurring mental disorders among Dutch adolescents admitted for acute alcohol intoxication. Secondly, this study aims to explore the cross-sectional relationship between the co-occurrence of mental disorders and patient characteristics, such as sex, age and blood alcohol concentration at admittance. Data were retrospectively collected from 726 adolescents admitted for acute alcohol intoxication. Overall, 245 (34%) of the 726 adolescents treated for acute alcohol intoxication were diagnosed with a co-occurring mental health disorder, such as attention-deficit hyperactivity disorder (13%) or autism spectrum disorder (2.1%). Attention-deficit hyperactivity disorder in particular seems to be more prevalent in the study population than in the general Dutch adolescent population.Conclusion: This study demonstrates that among adolescents admitted for acute alcohol intoxication, the prevalence of co-occurring mental disorders is a common and a relevant issue for treatment and prevention strategies. What is Known: • Alcohol consumption among adolescents has been associated with negative psychosocial effect. • Among adolescents admitted for acute alcohol intoxication, risk factors for psychological dysfunction appear to be inadequately assessed, documented and followed up. What is New: • The current study reports on the prevalence of co-occurring mental disorders among a substantial sample of adolescents admitted for acute alcohol intoxication. • Understanding the prevalence of co-occurring mental disorders is clinically relevant for the outpatient follow-up of adolescents admitted for acute alcohol intoxication.

Age at First Alcohol Use as a Possible Risk Factor for Adolescent Acute Alcohol Intoxication Hospital Admission in the Netherlands.

BACKGROUND: The primary objective of this study is to determine whether age at first alcohol use is a determinant for adolescent acute alcohol intoxication characteristics, such as age at first acute alcohol intoxication and blood alcohol concentration (BAC) at hospital admission. Around the world, as in the Netherlands, a key aim of alcohol policy is to postpone the age at first alcohol use. This is based on cohort studies that indicate a relationship between a younger age at first alcohol use and subsequent adult alcohol use disorders. METHODS: This study was conducted using a cohort of data comprising individuals under 18 years of age. Data were collected between 2007 and 2017 by the Dutch Pediatric Surveillance System (NSCK) in order to monitor trends in admissions for acute alcohol intoxication. Multivariate linear regression analyses were used to determine the association between age at first alcohol use and acute alcohol intoxication characteristics, such as age at first acute alcohol intoxication and BAC at admission. RESULTS: This study indicates that among adolescents admitted for acute alcohol intoxication, adolescents who started drinking at ≤ 14 years of age are significantly more often female, lower educated, and raised in nontraditional family structures than adolescents who started drinking between 15 and 18 years of age. Multiple linear regression analyses indicated that age at first alcohol use, corrected for covariates, significantly predicted the age at acute alcohol intoxication and BAC at admission. The association between age at first alcohol use and age at intoxication was also found to be clinically relevant. CONCLUSIONS: Although causation cannot be implied based on the results of these analyses, the results of this study suggest that interventions delaying the age at first alcohol use could be successful in increasing the average age that adolescents are admitted to the hospital for acute alcohol intoxication.

Gender, age, and educational level attribute to blood alcohol concentration in hospitalized intoxicated adolescents; a cohort study.

BACKGROUND: The prevalence of adolescents hospitalized with acute alcohol intoxication, mainly because of severe reduced consciousness, is increasing. However, the characteristics of these adolescents are mainly unidentified. In this clinical research, we aimed to identify factors that attribute to higher ethanol concentration, on which targeted alcohol health interventions can be designed. METHODS: Since 2007, alcohol intoxication among adolescents has been one of the leading topics of the Dutch Pediatric Surveillance System. In the current study, we have analyzed which demographic characteristics, general alcohol use behaviors, and clinical intoxication data were related to the blood alcohol concentration (BAC) levels at hospital admittance. We included all adolescents aged <18 years, admitted with BAC >0.0 g/l, and reduced consciousness during the years 2007, 2008, 2009, and 2010. RESULTS: A total of 2,023 adolescents with alcohol intoxication were reported, and 1,618 questionnaires were returned, of which 1,350 met our inclusion criteria. In univariate analysis, age, gender, educational level, place of alcohol purchase, place of alcohol consumption, age of first drink, and regular alcohol use during the weekend correlated with higher BAC. After multivariate analysis, older adolescents, boys, and higher educational level significantly attributed to higher BAC at admittance. CONCLUSIONS: In alcohol-intoxicated adolescents with reduced consciousness, gender, age, and also educational level correlate with BAC at admittance. Explanatory factors could be found in sensitivity to alcohol, but also in socioeconomic factors, which influence availability. Intervention strategies could be targeted more specific now for the subgroups found in this study to decrease the growing burden of adolescent alcohol intoxication, both on the societal level and on the clinical level.

Adolescent alcohol intoxication in Dutch hospital centers of pediatrics: characteristics and gender differences.

Gender differences in alcohol intoxication among adolescents are still largely unknown, whereas these differences have been studied in adults. To investigate possible differences, this study analyzed pediatric admissions for alcohol intoxication to the majority of Dutch hospitals between 2007 and 2009. Another aim was to explore key characteristics (e.g. blood alcohol concentration, duration of reduced consciousness, and age) and trends of alcohol intoxication among adolescents in the period 2007-2009. We analyzed data from the Dutch Pediatric Surveillance system, which monitors alcohol intoxication among children in pediatric departments of Dutch hospitals. Patients aged 11-17 years with reduced consciousness due to alcohol intoxication were included. The number of adolescents admitted with alcohol intoxication increased sharply from 2007 to 2009. The average age of the patients treated for alcohol intoxication increased from 15.3 years in 2007 and 15.4 years in 2008 to 15.7 years in 2009. The duration of reduced consciousness due to alcohol intoxication also increased over the 3-year period: from 2.2 to 3.1 h. Gender differences were observed regarding alcohol intoxication characteristics. Most strikingly, intoxicated girls were younger (15.3 vs. 15.7 years), had a lower blood alcohol concentration (1.79 vs. 1.94 g/l) and were hospitalized for shorter times than boys. No association was found between alcohol intoxication and other, possibly illicit drug use. The drinks most consumed prior to hospital admission were spirits and beer. Alcohol intoxication among adolescents is an emerging problem. Differences in intoxication characteristics between boys and girls were observed. These findings are important for future prevention and intervention strategies. In the Netherlands, special policlinics for children with alcohol intoxication have already been established.

[Ten years of alcohol intoxication among young people in The Netherlands]. / 10 jaar alcoholintoxicaties bij jongeren.

OBJECTIVE: To provide insight into the number of adolescents admitted to hospital with alcohol intoxication in the period 2007-2016. DESIGN: Observational cross-sectional study. METHODS: We used data from the hospital admissions for alcohol intoxication among minors that had been reported to the Dutch Paediatric Surveillance System (NSCK). We also used data on minors who had been admitted to hospital for other alcohol-related reasons. RESULTS: In the period 2007-2016, 4,674 minors were admitted to a hospital in the Netherlands with alcohol intoxication. The number of minors admitted with alcohol intoxication increased annually from 2007 to 2011, after which it became reasonably stable, with a peak in 2015. The average age at which a minor was admitted increased (2007: 14.9 years; 2016: 15.5 years), and this also applied to the duration of loss of consciousness (2007: 2.24 hours; 2016: 3.12 hours). Parents of young people admitted with alcohol intoxication have become markedly stricter; 69% had given permission for consumption of alcohol in 2011; in 2016 that had decreased to 19%. CONCLUSION: Raising the minimum age for obtaining low-alcohol drinks, the creation of better awareness of the consequences of alcohol use and the opening of the Outpatient Adolescents and Alcohol Clinics seem to have had an effect. The average age of young people with alcohol intoxication has increased and parents have become stricter, but binge-drinking is still a serious problem. Further research is needed into characteristics and treatment of the group of young people who end up in hospital.
