Covid-19 shelter-in-place, modified reopening orders, and order compliance impact on adolescent alcohol use and drinking contexts in California: A longitudinal analysis

Abstract

IntroductionThis study evaluated how Shelter-in-Place (SIP), modified reopening orders, and self-reported compliance with these orders have affected adolescent alcohol frequency and quantity of use across contexts during the COVID-19 pandemic. Materials and MethodsDifferences-in-differences (DID) models and multi-level modeling analyses were conducted on longitudinal data collected as part of a larger study on alcohol use among adolescents in California. 1,350 adolescents at baseline contributed 7,467 observations for a baseline and 5 six-month follow-up surveys. Analytic samples ranged from 3,577–6,245 participant observations based on models. Alcohol use outcomes included participant frequency (days) and quantity (number of whole drinks) of alcohol use in past 1-month and past 6-month periods. Context-specific alcohol use outcomes included past 6-month frequency and quantity of use at: restaurants, bars/nightclubs, outside, one’s own home, another’s home, and fraternities/sororities. Participant self-reported compliance with orders in essential business/retail spaces and at outdoor/social settings were also assessed. ResultsOur DID results indicated that being under a modified reopening order was associated with decreases in past 6-month quantity of alcohol use (IRR = 0.72, CI = 0.56–0.93, p < 0.05). Higher self-reported compliance with SIP orders related to social outdoor/social settings was associated with decreases in overall drinking frequency and quantity as well as decreases in frequency and quantity of alcohol use in all contexts in the past six months. Compliance with SIP orders impacting essential businesses and retail spaces was associated with decreased frequency and quantity of use at other’s home and outdoors. ConclusionsResults suggest that SIP and modified reopening policies may not directly affect adolescent alcohol use or drinking contexts, and that individual compliance with such orders may be a protective factor for alcohol use.
