More Drinking, More Problems-Stable Association Between Alcohol Consumption and Harm Among Swedish Youth 1995-2012

17 Is the New 15: Changing Alcohol Consumption among Swedish Youth

To examine and compare trends in drinking prevalence in nationally representative samples of Swedish 9th and 11th grade students between 2000 and 2018. A further aim is to compare drinking behaviours in the two age groups during years with similar drinking prevalence. Data were drawn from annual surveys of a nationally representative sample of students in year 9 (15-16 years old) and year 11 (17-18 years old). The data covered 19 years for year 9 and 16 years for year 11. Two reference years where the prevalence of drinking was similar were extracted for further comparison, 2018 for year 11 (n = 4878) and 2005 for year 9 (n = 5423). The reference years were compared with regard to the volume of drinking, heavy episodic drinking, having had an accident and quarrelling while drunk. The prevalence of drinking declined in both age groups during the study period. The rate of decline was somewhat higher among year 9 students. In 2018, the prevalence of drinking was the same for year 11 students as it was for year 9 students in 2005. The volume of drinking was lower among year 11 students in 2018 than year 9 students in 2005. No differences were observed for heavy episodic drinking. The decline in drinking has caused a displacement of consumption so that today's 17-18-year-olds have a similar drinking behaviour to what 15-16-year-olds had in 2005.

Parental education differentially predicts young adults' frequency and quantity of alcohol use in a longitudinal Swedish sample

Background

Alcohol consumption contributes to health inequalities, but few studies have examined how socially differentiated alcohol use develops across the life course. In this study, we examine how one aspect of childhood socioeconomic position (parental education) relates to two often-conflated young adult drinking patterns: drinking frequency and quantity per occasion. Using a life course perspective, we also explore whether parental drinking patterns or young adults’ own educational attainment might account for such associations.

Methods

This study used longitudinal data from the nationally representative Swedish Level of Living Surveys (LNU). Young adults’ (aged 20–28, n = 803) drinking patterns and educational attainment were determined through the LNU 2010 and official registers. A decade earlier, parents self-reported their education and drinking patterns in the LNU 2000 and Partner-LNU 2000.

Results

Logistic regression models showed that high parental education predicted young adult frequent drinking, while low parental education predicted young adult high quantity drinking. Drinking patterns were associated inter-generationally, but parental alcohol use did not account for differences in young adult drinking patterns by parental education. Young adults’ own education similarly predicted their drinking patterns but did not account for differences in drinking frequency by parental education. Differences in drinking quantity by parental education were no longer significant when young adults’ own education was included in the final model.

Conclusions

Findings suggest that parental education constitutes an early-life structural position that confers differential risk for young adult drinking patterns. Young adults whose parents had low education were less likely to drink frequently but were more likely to drink heavily per occasion, a drinking pattern that may place more disadvantaged young adults at a greater health risk.

•

High parental education predicts young adult frequent drinking.

•

Low parental education predicts young adult high quantity drinking.

•

Drinking patterns were associated inter-generationally.

•

Young adults’ education predicted their drinking patterns.

•

After adjusting for relevant pathways, an effect of parental education remains.
