Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="add12397-sec-0001" sec-type="section"> <title>Aims</title> <p>To examine relationships between characteristics of the local alcohol environment and adolescent alcohol use and beliefs in 50 California cities.</p> </sec> <sec id="add12397-sec-0002" sec-type="section"> <title>Design</title> <p>The study used longitudinal survey data collected from adolescents; city‐level measures of local alcohol policy comprehensiveness, policy enforcement, adult drinking and bar density; and multi‐level modeling with three levels (city, individual, time), allowing for random effects. Models included interaction terms (time × alcohol environment characteristics) and main effects, controlling for city and youth demographic characteristics. Analyses also examined possible mediating effects of alcohol‐related beliefs.</p> </sec> <sec id="add12397-sec-0003" sec-type="section"> <title>Setting</title> <p>Fifty California cities (50 000–500 000 population).</p> </sec> <sec id="add12397-sec-0004" sec-type="section"> <title>Participants</title> <p>Random samples of 1478 adolescents and 8553 adults.</p> </sec> <sec id="add12397-sec-0005" sec-type="section"> <title>Measurements</title> <p>Past‐year alcohol use and heavy drinking, and alcohol‐related beliefs (e.g. perceived alcohol availability) among adolescents; past 28‐day alcohol use among adults; ratings of local alcohol control policies; funding for enforcement activities; bars per roadway mile.</p> </sec> <sec id="add12397-sec-0006" sec-type="section"> <title>Findings</title> <p>Local alcohol policy comprehensiveness and enforcement were associated with lower levels of past‐year alcohol use (betas = −0.003 and −0.085, <italic>P</italic> < 0.05). Bar density was associated with a higher level of past‐year alcohol use (beta = 1.086, <italic>P</italic> < 0.01). A greater increase in past‐year alcohol use and heavy drinking over time was observed among adolescents living in cities with higher levels of adult drinking (betas = 0.224 and 0.108, <italic>P</italic> < 0.01).

Change in adolescents' drinking appears to be influenced by community‐level adult drinking. Bar density effects appear to be mediated through perceived alcohol availability and approval of alcohol use.</p> </sec> </abstract>
