Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A pilot trial among ship-board US Navy personnel surrounding a holiday weekend tested an evidence-based video on responsible drinking. Service members \>18 years were eligible to volunteer if they were aboard during data collection. Participants were randomized to intervention or control arms, with all given a brief survey before (T1) and after (T2) the weekend. The intervention arm viewed a 3-minute video at T1. A urine specimen collected at T1 and T2 for ethyl glucuronide (EtG) measurement used \>100ng/ml for significant alcohol use. Multivariable regression measured odds of detecting EtG at T2, controlling for T1 EtG detectability, age, and alcohol misuse at baseline per AUDIT-C. 86 subjects participated at T1, and 100 at T2, with complete data for 72 (control, n=34; intervention, n=38) who participated in both T1 and T2 were analyzed. Average age was 28 years with 25% and 32% reporting white or black/African-American, 54% married and 84% \<E6. At T1, 22% (n=16) and T2, 32% (n=23) had EtG\>100ng/ml. At T1, 50% and 55% in control and intervention arms respectively, screened positive for alcohol misuse by AUDIT-C; T1 AUDIT-C screen positivity was significantly associated with detecting EtG\>100ng/ml at T1 (p=0.04). Control arm EtG\>100ng/ml participants increased 1.7-fold over the weekend, from n=7 at T1 to n=12 at T2; the intervention arm had no increase in EtG\>100ng/ml participants, with n=11 at T1 and n=11 at T2.
