Alcohol and cannabis use and co-use among Whites and Hispanics on and off the U.S./Mexico border in California.

This paper examines self-reported rates of drinking and cannabis use and co-use among White and Hispanic adults randomly selected in four counties in California: Imperial on the border; and Kern, Tulare, and Madera in California's Central Valley. Co-use was significantly higher among the U.S.

Did the association between alcohol outlet density and crime change during COVID shelter-in-place orders?

Introduction: We investigated whether greater concentrations of on- and off-sale alcohol outlets were associated with crime and whether this association was moderated by COVID-19 shelter-in-place orders (SIP) that restricted on-premises consumption of alcohol.

Methods: Crimes (2019-2020) and addresses of licenced alcohol outlets in a medium-sized California city were geocoded within census block groups (N = 61). On- and off-sale alcohol outlet density was calculated as licenced outlets/2.

Gender moderates the association between posttraumatic stress disorder and mutual intimate partner violence in an emergency department sample.

Introduction: Patients in emergency departments (EDs) constitute a diverse population with multiple health-related risk factors, many of which are associated with intimate partner violence (IPV). This paper examines the interaction effect of depression, posttraumatic stress disorder (PTSD), impulsivity, drug use, adverse childhood experiences (ACEs), at-risk drinking, and having a hazardous drinker partner with gender on mutual physical IPV in an urban ED sample.

Methods: Research assistants surveyed 1037 married, cohabiting, or partnered patients in face-to-face interviews (87% response rate) regarding IPV exposure, alcohol and drug use, psychological distress, ACEs, and other sociodemographic features.

A statewide study of disparities in local policies and tobacco, vape, and cannabis retail environments.

The current study: (1) assesses sociodemographic disparities in local policies related to tobacco and cannabis retail, and (2) examines the cross-sectional association between policy strength and retailer densities of tobacco, e-cigarette (vape), and cannabis retailers within California cities and county unincorporated areas (N = 539). We combined (a) American Community Survey data (2019 5-year estimates), (b) 2018 tobacco, vape, and cannabis retailer locations from a commercial data provider, (c) 2017 tobacco and vape retail environment policy data from American Lung Association, and (d) 2018 cannabis policy data from California Cannabis Local Laws Database. Conditional autoregressive models examined policy strength associations with sociodemographic composition and retailer density in California jurisdictions.

Drinking and driving among Whites and Hispanics on and off the US/Mexico border in California.

Objective: To examine self-reported rates of driving under the influence (DUI) with and without arrest among border and non-border residents in California.

Methods: Data were obtained from 1,209 adults 18 to 39 years of age resident in four counties in California: Imperial on the U.S.

Micro-temporal analyses of crime related to alcohol outlets: A comparison of outcomes over weekday, weekend, daytime and nighttime hours.

Introduction: Causal relationships between alcohol outlets and crime are inferred from their statistical associations across neighbourhoods. However, many unobserved covariates may confound these effects. Recognising that outlet sales vary by time of day and day of week, we assess whether areas with more bars/pubs, restaurants or off-premise outlets have more crime during days and times when alcohol sales are greatest.

Contexts of Drinking- and Alcohol-Related Problems Among Whites and Hispanics on and off the US/Mexico border in California.

Background: This paper examines the association between drinking context use by Whites and Hispanics on and off the US/Mexico border and alcohol problems.

Methods: Data come from a household sample of 1209 adults 18 to 39 years of age resident in Imperial County on the California/Mexico border; and Kern, Tulare, and Madera in California's Central Valley. Data were collected on the phone or online and analyzed with an ordinal generalized linear model.

Equity in Coverage of Local Cannabis Control Policies in California, 2020‒2021.

To assess whether cannabis control policies that may protect public health were adopted evenly across California localities with differing sociodemographic compositions. From November 2020 to January 2021, we measured cannabis control policies for 241 localities across California and linked them to data on the characteristics of the communities affected by these policies. We evaluated whether disadvantaged communities were more likely to allow cannabis businesses and less likely to be covered by policies designed to protect public health.

Alcohol use disorder among Whites and Hispanics on and off the U.S./Mexico border in California.

This paper examines whether U.S./Mexico border residence in California is related to the prevalence of DSM-5 alcohol use disorder (AUD) among Whites and Hispanics.

A Spatiotemporal Analysis of the Association of California City and County Cannabis Policies with Cannabis Outlet Densities.

Background: Cannabis outlets may affect health and health disparities. Local governments can regulate outlets, but little is known about the effectiveness of local policies in limiting outlet densities and discouraging disproportionate placement of outlets in vulnerable neighborhoods.

Methods: For 241 localities in California, we measured seven policies pertaining to density or location of recreational cannabis outlets.

Trends and correlates of spatially aggregated alcohol-involved crashes among Whites and Hispanics in California.

Aims: This paper examines trends and correlates of alcohol-involved motor vehicle crashes (AMVCs) in California between 2005 and 2016 among Hispanic and non-Hispanic Whites (Whites hereafter). Together these two groups comprise 76% of the state population. The paper also examines whether alcohol outlet density, percentage of Hispanics in census tract populations, and distance to the U.

Association of Cannabis Use and At-Risk Alcohol Use With Intimate Partner Violence in an Urban ED Sample.

Introduction: Urban ED patients have elevated rates of substance use and intimate partner violence. The purpose of this study is to describe the risk profiles for intimate partner violence among urban ED patients who report at-risk alcohol use only, cannabis use only, or both types of substance use.

Methods: Cross-sectional survey data were collected from study participants (N = 1037; 53% female; ages 18-50) following informed consent.

Population-Based Correlates of Spatially Aggregated Drug-Related Arrests On and Off the U.S.-Mexico Border in California.

Objective: The purpose of this study was to examine drug-related arrest rates in California from 2005 to 2017 with a focus on the measurement of presumptive excess arrests across areas proximate to the U.S.-Mexico border.

Ethnic density effect on alcohol-related hospitalizations among Chinese enclaves and ethnoburbs in California, 2007-2011.

Introduction: Research suggests there is an 'ethnic density effect' whereby racial/ethnic minority populations appear healthier when they reside in neighborhoods with greater numbers of people from the same ethnic group. The purpose of this study is to test whether this effect is observed for residents in Chinese enclaves (immigrant neighborhoods in urban areas) and ethnoburbs (immigrant neighborhoods in suburban areas) for measures on alcohol abuse and dependence.

Methods: ZIP code areas of California that represented Chinese enclaves and ethnoburbs were identified and mapped.

Drinking in Mexico by Whites and Hispanics on and off the US/Mexico border in California.

This paper compares drinking patterns of Whites and Hispanics who after crossing the U.S./Mexico border drink and do not drink in Mexico.

Interrelationships of Economic Stressors, Mental Health Problems, Substance Use, and Intimate Partner Violence among Hispanic Emergency Department Patients: The Role of Language-Based Acculturation.

We analyzed the interrelationships of economic stressors, mental health problems, substance use, and intimate partner violence (IPV) among a sample of Hispanic emergency department patients and probed if Spanish language preference, which may represent low acculturation and/or immigrant status, had a protective effect, in accordance with the Hispanic health paradox. Study participants ( = 520; 50% female; 71% Spanish speakers) provided cross-sectional survey data. Gender-stratified logistic regression models were estimated for mental health problems (PTSD, anxiety, depression), substance use (risky drinking, cannabis, illicit drug use), and IPV.

Proximity to the U.S./Mexico border, alcohol outlet density and population-based sociodemographic correlates of spatially aggregated violent crimes in California.

This paper examines trends and population-level correlates of violent crime rates from 2005 to 2017 in California, including proximity to the U.S./Mexico border and alcohol outlet density.

Frequency of Intimate Partner Violence among an Urban Emergency Department Sample: A Multilevel Analysis.

Intimate partner violence (IPV) is a pervasive public health problem. Within the U.S.

Drinking Context-Specific Dose-Response Models of Intimate Partner Violence Among an Urban Emergency Department Sample.

Objective: This cross-sectional study evaluates the association between physical intimate partner violence (IPV) and frequencies of drinking and volume consumed in six different contexts among a sample of urban emergency department (ED) patients.

Method: We obtained survey data from 1,037 married, cohabiting, or partnered patients (53% female; 50% Hispanic; 29% African American) at a Northern California safety-net hospital. Past-year physical IPV was measured with the Revised Conflict Tactics Scale.

Adverse childhood experiences are associated with at-risk drinking, cannabis and illicit drug use in females but not males: an Emergency Department study.

Background: Adverse childhood experiences (ACEs) are associated with adult substance use in the general population. Given pervasive health disparities among underserved populations, understanding how ACEs are associated with substance use among urban Emergency Department (ED) patients could help inform design of effective screening, brief interventions, and referral to treatment.

Objectives: To estimate gender differences in prevalence of separate and cumulative ACEs among a sample of urban ED patients, and assess its association with at-risk drinking (4+/5+ drinks for females/males), cannabis, and illicit drug use.

Predicting the Future Course of Opioid Overdose Mortality: An Example From Two US States.

Background: The rapid growth of opioid abuse and the related mortality across the United States has spurred the development of predictive models for the allocation of public health resources. These models should characterize heterogeneous growth across states using a drug epidemic framework that enables assessments of epidemic onset, rates of growth, and limited capacities for epidemic growth.

Methods: We used opioid overdose mortality data for 146 North and South Carolina counties from 2001 through 2014 to compare the retrodictive and predictive performance of a logistic growth model that parameterizes onsets, growth, and carrying capacity within a traditional Bayesian Poisson space-time model.

Impacts of confounding roadway characteristics on estimates of associations between alcohol outlet densities and alcohol-related motor vehicle crashes.

Introduction And Aims: Previous research on alcohol-related motor vehicle crashes (AMVC) share a substantial limitation: sources of geographic variations in background crash risks may confound estimated spatial relationships between alcohol outlets and AMVCs. The aim of this study was to address this concern by examining, spatial-temporally, relationships between alcohol outlets and AMVCs adjusting for a set of six roadway characteristics that may be, independently, related to crash risks. While most similar studies focus on one metropolitan area, we use a unique sample of 50 cities.

Proximity to the Southern Border and Sociodemographic Correlates of Drinking and Driving Arrests in California.

Background: About 30% of all motor vehicle fatalities in the United States are associated with alcohol-impaired motor vehicle crashes. Arrests for drinking and driving (Driving under the influence [DUI]) are 1 of the most important deterrence actions to minimize DUI. This paper examines trends and population-level correlates of drinking driving arrests (DUI) from 2005 to 2017 in California.

Multiresolution Analyses of Neighborhood Correlates of Crime: Smaller Is Not Better.

Population analyses of the correlates of neighborhood crime implicitly assume that a single spatial unit can be used to assess neighborhood effects. However, no single spatial unit may be suitable for analyses of the many social determinants of crime. Instead, effects may appear at multiple spatial resolutions, with some determinants acting broadly, others locally, and still others as some function of both global and local conditions.

Association of Medicaid Expansion With Opioid Overdose Mortality in the United States.

Importance: The Patient Protection and Affordable Care Act (ACA) permits states to expand Medicaid coverage for most low-income adults to 138% of the federal poverty level and requires the provision of mental health and substance use disorder services on parity with other medical and surgical services. Uptake of substance use disorder services with medications for opioid use disorder has increased more in Medicaid expansion states than in nonexpansion states, but whether ACA-related Medicaid expansion is associated with county-level opioid overdose mortality has not been examined.

Objective: To examine whether Medicaid expansion is associated with county × year counts of opioid overdose deaths overall and by class of opioid.
