Academic orientation and alcohol-related harm among adolescents : Does the inclusion of a disadvantaged group add to the social gradient?

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. Negative binomial regressions estimated the relationship between academic orientation (higher education preparatory; HEP, vocational; VP and introductory; IP) and ARH. To assess the contribution of explanatory factors, we estimated models that included risk factors such as heavy episodic drinking (HED).

RESULTS

A graded association was observed between academic orientation and ARH, with more ARH among students in IP (IRR = 1.79) and VP (IRR = 1.43) than in HEP. Adjustments for risk factors attenuated the estimates by approximately half, but there was still 14% more ARH in VP and 50% more in IP than in HEP. The additive interaction test indicated a positive and significant interaction for students in VP who engaged in HED, versus students in HEP, who did not.

CONCLUSION

The findings suggest a negative gradient in the association between academic orientation and ARH, where the students in IP experienced the highest levels of ARH. While differential exposure and vulnerability to HED account for a significant proportion of the excess risk among VP students, HED seems to be less important relative to other risk factors among IP students. More research is needed to identify the mechanisms underlying the elevated levels of ARH among the most disadvantaged group-students enrolled in IP.
