The Causal Role of Alcohol Use in Adolescent Externalizing and Internalizing Problems: A Mendelian Randomization Study

Chao, Miao, Li, Xinying, McGue, Matt·2017·Alcoholism: Clinical and Experimental Research

Abstract

Background: The co‐occurrence of alcohol use and externalizing/internalizing problems threatens adolescents’ mental health. Research on whether alcohol use and these problems are causal and the direction of the potential causal relationships is needed to understand the mechanisms of the co‐occurrence. Methods: A Mendelian randomization analysis was conducted in which the aldehyde dehydrogenase 2 (ALDH 2) rs671 polymorphism was used as an instrumental variable for alcohol use phenotypes. In total, 1,608 Chinese adolescents (mean age 14.11 ± 1.83 years) were genotyped for the ALDH 2 rs671 polymorphism. Three externalizing problems (aggression, delinquency, and attention problems) were measured with the Youth Self‐Report inventory, and 2 internalizing problems (depression and anxiety) were measured with the self‐reported Children's Depression Inventory and the Trait subscale of the State‐Trait Anxiety Inventory. Results: Alcohol use was positively associated with all 3 externalizing and 2 internalizing problems, and the ALDH 2 polymorphism had a significant effect on alcohol use. Aggression and attention problems were also significantly affected by the ALDH 2 polymorphism, whereas no significant association was observed between the ALDH 2 polymorphism and delinquency, anxiety, or depression. Conclusions: The results suggest that alcohol use is a cause of adolescent aggression and attention problems but not adolescent delinquency, anxiety, or depression.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Aggression scores were ALDH2 nondeficient: M = 50.37 (SD = 10.04), ALDH2 deficient: M = 49.18 (SD = 9.90), p = 0.033.

  • Path estimates indicated that ALDH2 deficiency was associated with a lower alcohol use frequency, reduced quantity, and lower desire, which in turn was associated with less aggressive behavior.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
