Strong concordance and correlation between direct alcohol biomarkers and alcohol self-report among youth with variable drinking patterns.

ABSTRACT:

Background

Heavy drinking among adolescents is associated with various consequences but is often undetected, limiting early intervention. Self-report of alcohol use has strengths but can be inaccurate due to recall biases and underreporting. Objective biomarkers may improve detection of drinking and related consequences, but few adolescent studies have assessed biomarker concordance with subjective self-report.

Methods

Youth aged 15-19 (54 % female) with minimal (n = 22) or heavy (n = 56) drinking patterns attended two research-related visits, approximately 13 days apart. Biospecimens were collected at both visits for urine ethylglucuronide (EtG) quantification (100ng/ml cutoff) and at visit two for whole blood phosphatidylethanol (PEth) quantification (20ng/ml cutoff).
