Background: This study aimed to examine the social gradient in self-reported alcohol-related harm (ARH) among young alcohol consumers by including a largely overlooked group of adolescents. We also explored the extent to which such a gradient could be attributed to differential exposure or differential vulnerability to risk factors.
Method: Cross-sectional survey of upper-secondary students (n = 2996) in Sweden.
Aim: To examine the association between academic orientation and frequent cannabis use among Swedish adolescents in upper secondary school and include pupils from introductory programs (IPs), a large group of adolescents previously overlooked in research on adolescent cannabis use.
Methods: We used cross-sectional data from two anonymous school surveys carried out in upper secondary school in 2021. The samples consisted of pupils from all academic orientations, and the analysis included 3151 pupils in higher education preparatory programs (HEPs), 1010 pupils in vocational programs (VPs), and 819 pupils in IPs.
Introduction: To examine gender differences in drinking habits among Swedish ninth graders over the period 1989-2021.
Methods: Annual school surveys with nationally representative samples of ninth-grade students in Sweden covering the period 1989-2021, total sample of 180,538 students. Drinking habits were measured with self-reports of frequency and quantity of use and frequency of heavy episodic drinking.
Article Synopsis
- Alcohol use among adolescents in Nordic countries has decreased significantly, with the exception of Denmark, while cannabis use remains low and stable overall.
- Data analyzed from a survey of 15- to 16-year-olds from 2003 to 2019 indicates a decline in total substance use occasions among adolescents.
- The study suggests that cannabis use is increasingly substituting or co-occurring with alcohol use, supporting the 'substitution' and 'hardening' hypotheses, but not the idea that both substances are declining in parallel.
Background: Few studies have assessed how children are affected by parental alcohol consumption without clinically diagnosed alcohol problems, especially in relation to more long-term and severe consequences. The aim is to investigate how fathers' alcohol use is related to the risk for substance-related disorders in offspring.
Method: A prospective cohort study of 64 710 Swedish citizens whose fathers were conscripted for compulsory military training at ages 18-20 in 1969/70.
Article Synopsis
- The study investigates the relationship between childhood socioeconomic status (SES) and cannabis use among adolescents in Sweden, noting inconsistencies in previous research.
- Using data from over 9,000 11th graders, researchers found that students with at least one parent with a university education had a higher likelihood of trying cannabis but were less frequent users compared to those with no college education.
- The findings suggest that while lower SES families may have adolescents who are less likely to experiment with cannabis, those who do may use it more frequently, indicating a complex relationship between SES and cannabis use.
Aims: The study aims to examine how socio-economic status (SES) among youth is related to binge-drinking and alcohol-related problems using three SES indicators: (i) SES of origin (parental education level), (ii) SES of the school environment (average parental education level at student's school) and (iii) SES of destination (academic orientation).
Methods: Cross-sectional data on upper secondary students (n= 4448) in Sweden. Multilevel logistic and negative binomial regression were used to estimate the relationship between each SES indicator and binge-drinking and alcohol-related problems, respectively.
Aims: Alcohol consumption among Swedish youth increased during the 1990s. In the following decade, levels declined coinciding with a reduction in the prevalence of self-reported alcohol-related harm. We examine how the trend in self-reported alcohol-related problems among young Swedish alcohol consumers has followed the trend in alcohol consumption during 1995-2012, and test whether the strength of the association between self-reported alcohol consumption and alcohol-related problems within individuals is inversely proportional to the overall level of consumption among youth.
