One-Year Association of Drug Possession Law Change With Fatal Drug Overdose in Oregon and Washington.

Importance: Two states modified laws to remove or substantially reduce criminal penalties for any drug possession. The hypothesis was that removing criminal penalties for drug possession may reduce fatal drug overdoses due to reduced incarceration and increased calls for help at the scene of an overdose. Objective: To evaluate whether decriminalization of drug possession in Oregon and Washington was associated with changes in either direction in fatal drug overdose rates. Design, Setting, and Participants: This cohort study used a synthetic control method approach to examine whether there were changes in drug possession laws and fatal drug overdose rates in Oregon and Washington in the postpolicy period (February 1, 2021, to March 31, 2022, in Oregon and March 1, 2021, to March 31, 2022, in Washington). A counterfactual comparison group (synthetic controls) was created for Oregon and Washington, using 48 states and the District of Columbia, that did not implement similar policies during the study period (January 1, 2018, to March 31, 2022). For 2018-2021, final multiple cause-of-death data from the National Vital Statistics System (NVSS) were used. For 2022, provisional NVSS data were used. Drug overdose deaths were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision underlying cause-of-death codes X40-X44, X60-X64, X85, and Y10-Y14. Exposures: In Oregon, Measure 110 went into effect on February 1, 2021. In Washington, the Washington Supreme Court decision in State v Blake occurred on February 25, 2021. Main Outcome: Monthly fatal drug overdose rates. Results: Following the implementation of Measure 110, absolute monthly rate differences between Oregon and its synthetic control were not statistically significant (probability = 0.26). The average rate difference post Measure 110 was 0.268 fatal drug overdoses per 100 000 state population. Following the implementation of the policy change in Washington, the absolute monthly rate differences between Washington and synthetic Washington were not statistically significant (probability = 0.06). The average rate difference post Blake was 0.112 fatal drug overdoses per 100 000 state population. Conclusions and Relevance: This study found no evidence of an association between legal changes that removed or substantially reduced criminal penalties for drug possession in Oregon and Washington and fatal drug overdose rates. Additional research could examine potential other outcomes as well as longer-term associations with fatal drug overdose overall and across racial and ethnic groups.

Changes in arrests following decriminalization of low-level drug possession in Oregon and Washington.

BACKGROUND: Despite evidence that the U.S. "War on Drugs" is associated with increases in drug-related harm and other negative outcomes, all U.S. states have long criminalized most drug possession. In early 2021, both Oregon and Washington became exceptions to this rule when they fully (Oregon) or partially (Washington) decriminalized possession of small amounts of all drugs. METHODS: We obtained arrest data for 2019 to 2021 for intervention states (Oregon and Washington) and control states (Colorado, Idaho, Montana, and Nevada). We calculated monthly rates for arrests overall and for violent crimes, drug possession, equipment possession, non-drug crimes, and a set of low-level crimes termed displaced arrests. Using an interrupted time series analysis, we examined changes in monthly arrest rates after the implementation of policy change in Oregon and Washington compared to control states. RESULTS: In Oregon, there were 3 fewer drug possession arrests per 100,000 in the month after the policy change; the rate decreased throughout the post-implementation period. In Washington, there were almost 5 fewer drug possession arrests per 100,000 in the month following policy change, and the rate remained stable thereafter. Both declines were significantly greater than in comparison states. There were also statistically significant reductions in arrests for possession of drug equipment in Washington and a significant increase in displaced arrests in Oregon. There were no significant changes in overall arrests, non-drug arrests or arrests for violent crime in either state, relative to controls. CONCLUSION: This analysis demonstrates that it is possible for state drug decriminalization policies to dramatically reduce arrests for drug possession without increasing arrests for violent crimes, potentially reducing harm to people who use drugs and their communities. Additional research is needed to determine whether these legal reforms were associated with changes in overdose rates and other drug-related harms.

A tale of two cities: Racialized arrests following decriminalization and recreational legalization of cannabis.

BACKGROUND: In the U.S., "War on Drugs" policies have led to large and unequal increases in arrests among particularly of Black/African American men. The change in the legal status of cannabis may reduce the racial disparity in arrests. We examined the impact of changing legal status on arrest disparities. METHODS: We obtained publicly available deidentified cannabis arrest data from the District of Columbia (D.C.) Metropolitan Police Department (2012-2019) and Los Angeles (L.A.) Police Department (2010-2019). We examined the differences in average monthly cannabis arrest rates for each city and each outcome (possession, possession with intent to distribute, distribution, and public consumption) across racial groups. RESULTS: For both D.C. and L.A. following changes in the legal status of cannabis, we saw a decrease of the absolute disparity in possession-related arrests. There was also a reduction in D.C. for the relative disparity, but there was an increase in the relative disparity in L.A. In both cities, there was an emergence of public consumption-arrests. In D.C., there was an absolute increase of 4.0 (SD=2.5) more arrests per-month for Black people than white people and a relative increase of 9.1 (SD=1.5). In L.A., absolute disparity of 0.6(SD=1.3) and a relative disparity of 6.7 (SD=2.0). CONCLUSIONS: There was a reduction in the absolute arrest disparity for cannabis-related possession arrests following decriminalization and legalization in both D.C and L.A. However, we saw the emergence of arrests for public consumption. This emergence of possession arrests towards public consumptions arrests, underscores the need to examine arrests beyond possession.

Alcohol Enforcement in the United States From 2010 to 2019.

OBJECTIVE: Despite the important role of enforcement in reducing alcohol-related harms, few studies have assessed alcohol enforcement efforts, particularly over time. We assessed the prevalence of alcohol law enforcement strategies at two time points. METHOD: Of a random sample of U.S. local law enforcement agencies (i.e., police, sheriff) surveyed in 2010, 1,028 were resurveyed in 2019 (742/1,028 [72%] response rate). We assessed changes in alcohol enforcement strategies and priorities within three domains: (a) alcohol-impaired driving, (b) alcohol sales to obviously intoxicated patrons (i.e., overservice), and (c) underage drinking. RESULTS: Agencies reported placing higher priority on enforcement of alcohol-impaired driving and overservice in 2019 versus 2010. For alcohol-impaired driving enforcement strategies, we found increases over time in use of saturation patrols and in enforcing laws prohibiting open containers of alcohol in motor vehicles, but not in use of sobriety checkpoints. Approximately 25% of agencies conducted overservice enforcement in both years. For all strategies directed at underage drinking, enforcement decreased over time with more agencies using strategies aimed at underage drinkers versus alcohol suppliers (alcohol outlets, adults) in both years. CONCLUSIONS: Agencies reported continued low levels or declines in enforcement across most strategies despite reported increases in prioritizing alcohol enforcement. More agencies could adopt alcohol control enforcement strategies, including an increased focus on suppliers of alcohol to youth rather than on underage drinkers, and increased awareness and enforcement of selling alcohol to obviously intoxicated patrons. Use of these strategies has the potential to reduce health and safety consequences of excessive alcohol use.

Strategies Used by Local Law Enforcement Agencies to Prevent Overservice of Alcohol in the United States.

Overservice of alcohol, defined as commercial provision of alcohol to an individual who is obviously intoxicated, is illegal in most states and contributes to motor vehicle crashes and violence. Law enforcement agencies use various strategies that aim to reduce overservice at licensed alcohol establishments (e.g., bars, restaurants). Place of Last Drink (POLD) data collection is an emerging overservice enforcement strategy. POLD identifies patterns of overservice, which can provide support for targeted interventions to prevent overservice at offending establishments. We describe the prevalence of POLD and other overservice enforcement strategies and associations with agency characteristics, which has important implications for public health and safety. We conducted a national survey of 1024 municipal (e.g., town, city) and county law enforcement agencies in 2019 (response rate = 73%). We assessed the use of overservice enforcement strategies conducted by the agencies over the past year. We examined associations of each type of overservice enforcement strategy with agency and jurisdiction characteristics using regression models. 27% of responding agencies reported conducting overservice enforcement and 7% conducted POLD data collection specifically. Municipal (vs. county) agencies and agencies with an officer assigned primarily to alcohol enforcement activities were significantly more likely to conduct overservice enforcement generally but not POLD data collection specifically. Overservice enforcement in general, and POLD data collection specifically, are not widely conducted. Prevention of overservice has the potential to reduce harms related to excessive alcohol consumption. Increased evaluation of overservice enforcement strategies should be prioritized.

Do Alcohol Outlets Mediate the Effects of the Moving to Opportunity Experiment on Adolescent Excessive Drinking? A Secondary Analysis of a Randomized Controlled Trial.

Background: Housing mobility impacts adolescent alcohol use, and the neighborhood built environment may impact this relationship. Methods: Moving to Opportunity (MTO) was a multi-site, three-arm, household-level experiment. MTO randomly assigned one of three treatment arms (1994-1997) allowing families living in public housing to (1) receive a voucher to be redeemed any neighborhood (2) receive a voucher to be redeemed in a neighborhood with less than 10% poverty (3) remain in public housing (control). MTO decreased girls' alcohol use, but increased boys' alcohol use. Treatment groups were pooled because they are similar conceptually and statistically on our primary outcome. Among youth aged 12-19 in 2001-2002 (N = 2829), we estimated controlled direct effects mediation of MTO treatment effects on youth with housing vouchers (N = 1950) vs. controls (N = 879) on past 30-day number of drinks per day on days drank, using gender-stratified Poisson regression. Mediators were density of on- and off-premises alcohol outlets per square mile at the families' census tract of residence in 1997. Results: Treatment group youth were randomized to live in 1997 census tracts with lower off-premises, but higher on-premises, outlet density. MTO treatment (vs. controls) decreased drinking for girls via alcohol outlet density, but only at higher levels of outlet density. Treatment was 18% more beneficial when girls moved to high density neighborhoods, compared to controls who stayed living in public housing in high density neighborhoods. Conclusion: Additional social processes unmeasured in the current study may play an important role in the alcohol use and other health risks for girls.

Housing mobility protects against alcohol use for children with socioemotional health vulnerabilities: An experimental design.

PURPOSE: Neighborhood context may influence alcohol use, but effects may be heterogeneous, and prior evidence is threatened by confounding. We leveraged a housing voucher experiment to test whether housing vouchers' effects on alcohol use differed for families of children with and without socioemotional health or socioeconomic vulnerabilities. TRIAL DESIGN: In the Moving to Opportunity (MTO) study, low-income families in public housing in five US cities were randomized in 1994 to 1998 to receive one of three treatments: (1) a housing voucher redeemable in a low-poverty neighborhood plus housing counseling, (2) a housing voucher without locational restriction, or (3) no voucher (control). Alcohol use was assessed 10 to 15 years later (2008 to 2010) in youth ages 13 to 20, N = 4600, and their mothers, N = 3200. METHODS: Using intention-to-treat covariate-adjusted regression models, we interacted MTO treatment with baseline socioemotional health vulnerabilities, testing modifiers of treatment on alcohol use. RESULTS: We found treatment effect modification by socioemotional factors. For youth, MTO voucher treatment, compared with controls, reduced the odds of ever drinking alcohol if youth had behavior problems (OR = 0.26, 95% CI [0.09, 0.72]) or problems at school (OR = 0.46, [0.26, 0.82]). MTO low-poverty treatment (vs. controls) also reduced the number of drinks if their health required special medicine/equipment (OR = 0.50 [0.32, 0.80]). Yet treatment effects were nonsignificant among youth without socioemotional vulnerabilities. Among mothers of children with learning problems, MTO voucher treatment (vs. controls) reduced past-month drinking (OR = 0.69 [0.47, 0.99]), but was harmful otherwise (OR = 1.22 [0.99, 1.45]). CONCLUSIONS: For low-income adolescents with special needs/socioemotional problems, housing vouchers protect against alcohol use.

Racial Equity in Cannabis Policy: Diversity in the Massachusetts Adult-Use Industry at 18-months.

Background: Cannabis criminalization disproportionately harms communities of color in the United States. In Massachusetts' legal recreational ("adult-use") cannabis industry, state regulations intend to promote diverse participation. We assessed short-term racial/ethnic and gender diversity across the industry and in senior-level positions with greater opportunities to build wealth (i.e., board members, executives, directors). Methods: We extracted race/ethnicity and gender from required registration forms submitted to state regulators for each person working in a licensed adult-use cannabis business from October 2018 to April 2020 (n=4,883). We conducted descriptive analysis and negative binomial regression to assess characteristics associated with senior positions. Results: As of April 2020, racial/ethnic and gender diversity in the Massachusetts adult-use cannabis market (n=4,883) was 75% white, 7% Latino, 6% Black/African American, similar to the state labor market, and 65% male. Diversity was more limited in senior positions. Agents in senior positions (n=403) were 84% white, 2% Latino, 5% Black/African American, and 82% male. Senior-level participation was markedly low for women of color. Conclusion: Despite legislative and regulatory commitment, diversity lacks in senior positions in this emerging cannabis market. States considering adult-use cannabis markets, and those that have already done so, should monitor participation to identify inequities and adapt initiatives to ensure Black/African American and Latino communities socially and economically benefit from state legalization.

The Revolution Will Be Hard to Evaluate: How Co-Occurring Policy Changes Affect Research on the Health Effects of Social Policies.

Extensive empirical health research leverages variation in the timing and location of policy changes as quasi-experiments. Multiple social policies may be adopted simultaneously in the same locations, creating co-occurrence that must be addressed analytically for valid inferences. The pervasiveness and consequences of co-occurring policies have received limited attention. We analyzed a systematic sample of 13 social policy databases covering diverse domains including poverty, paid family leave, and tobacco use. We quantified policy co-occurrence in each database as the fraction of variation in each policy measure across different jurisdictions and times that could be explained by covariation with other policies. We used simulations to estimate the ratio of the variance of effect estimates under the observed policy co-occurrence to variance if policies were independent. Policy co-occurrence ranged from very high for state-level cannabis policies to low for country-level sexual minority-rights policies. For 65% of policies, greater than 90% of the place-time variation was explained by other policies. Policy co-occurrence increased the variance of effect estimates by a median of 57-fold. Co-occurring policies are common and pose a major methodological challenge to rigorously evaluating health effects of individual social policies. When uncontrolled, co-occurring policies confound one another, and when controlled, resulting positivity violations may substantially inflate the variance of estimated effects. Tools to enhance validity and precision for evaluating co-occurring policies are needed.

An examination of how alcohol enforcement strategies by sheriff and police agencies are associated with alcohol-impaired-driving fatal traffic crashes.

Objective: Over 10,000 people die in alcohol-impaired-driving traffic crashes every year in the U.S. Approximately half of alcohol-impaired drivers report their last drink was at a bar or restaurant, and most bars and restaurants serve alcohol to patrons who are already intoxicated, known as overservice. Law enforcement agencies use various strategies to address alcohol-impaired driving and overservice but research on the effectiveness of these strategies is limited. Our objective was to assess whether law enforcement efforts focusing on alcohol-impaired driving and alcohol overservice were associated with alcohol-impaired-driving fatal traffic crashes.Methods: We conducted a survey of police and sheriff agencies in 1,082 communities across the U.S. in 2010 regarding their alcohol enforcement practices. We assessed whether the agency conducted: (1) alcohol overservice enforcement and (2) alcohol-impaired driving enforcement (sobriety checkpoints, saturation patrols, open container, overall alcohol-impaired driving enforcement). From the Fatality Analysis Reporting System (2009-2013), we obtained counts of alcohol-impaired-driving fatal traffic crashes (at least one driver had blood alcohol content ≥ 0.08) within the agency's jurisdiction boundary and within a 10-mile buffer. Using multi-level regression, we assessed whether each enforcement type was associated with alcohol-impaired-driving fatal crashes (per 100,000 population). For both the jurisdiction boundary and 10-mile buffer, we ran stratified models based on community/agency type: (1) small town/rural police; (2) urban/suburban police and (3) sheriffs.Results: In jurisdiction boundary models, urban/suburban communities where police conducted overservice enforcement (compared to those that did not) had fewer alcohol-impaired-driving fatal crashes (5.0 vs. 6.6; p = 0.01). For the 10-mile buffer, small town/rural communities where police agencies conducted overservice enforcement (compared to those that did not) had fewer alcohol-impaired-driving fatal crashes (16.9 vs. 21.2; p = 0.01); we found similar results for small town/rural communities where police used saturation patrols (18.7 vs. 22.1; p = 0.05) and had overall high alcohol-impaired driving enforcement (18.7 vs. 22.1; p = 0.05). The direction and the size of the effects for other types of enforcement and agencies were similar, but not statistically significant.Conclusions: Alcohol enforcement strategies among police agencies in small town/rural communities may be particularly effective in reducing alcohol-impaired fatal traffic crashes. Results varied by enforcement, agency and community type.

The Effectiveness of Alcohol Impact Areas in Reducing Crime in Washington Neighborhoods.

BACKGROUND: We evaluated the effectiveness of Alcohol Impact Areas (AIA) in reducing crime around off-premise alcohol outlets in 3 AIAs in Spokane and Tacoma, Washington, using an interrupted time series design with comparison groups. AIAs only exist in Washington and include designated areas in a city where specific brands of malt liquor are restricted. We hypothesized that mandatory restrictions on malt liquor sales in AIAs would be significantly associated with decreases in crime, especially less-serious crime. METHODS: In Spokane and Tacoma, targets were 3 AIAs and 3 comparison areas with demographically similar neighborhoods without malt liquor restrictions in the same respective city. Nine different crime outcomes were evaluated: Part I selected crimes, Part II selected crimes (further split into nuisance crimes and other Part II crimes), assaults, vandalism, narcotics, disorderly conduct, and all selected crimes combined. Crime was typically compared 3 years prior to and 3 years following policy adoption using time series and negative-binomial modeling. Separate models were run for each area and each crime. RESULTS: Study hypotheses were partially supported. Malt liquor restrictions in AIAs were associated with significant decreases in crime, particularly certain Part II crimes and assaults (simple and aggravated) in 12 of the 23 models. The strength of the observed associations varied by AIA. Average monthly crime counts across all crime categories decreased more in the Tacoma AIA than in Spokane AIAs, and average monthly crime decreased more in Spokane AIA 2 (East Central) than in AIA 1 (Downtown Core). Malt liquor restrictions were significantly associated with increases in disorderly conduct in the Tacoma AIA; the increase, however, was small. CONCLUSIONS: Findings suggest that malt liquor policies such as AIAs may be one of a number of tools local officials can use to reduce alcohol-related crime in cities, especially less-serious crime.

A latent class analysis of heavy substance use in Young adulthood and impacts on physical, cognitive, and mental health outcomes in middle age.

BACKGROUND: This study examines whether longitudinal patterns of persistent or experimental heavy substance use across young adulthood were associated with physical and mental health in midlife. METHODS: Data (N = 21,347) from Monitoring the Future from adolescence (age 18) to midlife (age 40) were used. Repeated measures latent class analysis modeled patterns of patterns of cigarettes, alcohol, marijuana, and other illicit drugs across young adulthood (ages 18-30). Latent classes were then used as predictors of physical health problems, cognitive problems, self-rated health, and psychological problems in midlife (age 40), while controlling for sociodemographic variables (i.e., gender, race/ethnicity, parental education). RESULTS: Identified classes were "Extreme Heavy Users" (3.9%), "Early Young Adult Users" (8.9%), "Cigarette Smokers" (9.2%), "All But Cigarette Smokers" (5.0%), "Frequent Alcohol Bingers" (10.4%), and "Not-Heavy Users" (62.6%). Extreme Heavy Users, Early Young Adult Users, and Cigarette Smokers had significantly poorer overall health based on a number of physical conditions and self-rated health. Extreme Heavy Users, Early Young Adult Users, Cigarette Smokers, and All But Cigarette Smokers had more cognitive problems than other classes. Extreme Heavy Users, Early Young Adult Users, Cigarette Smokers, and All But Cigarette Smokers were more likely to see a health professional for a psychological problem. CONCLUSIONS: Patterns of heavy substance use were associated with health across decades. Regular cigarette smokers and heavy users across substances and ages had the worst health in midlife, although even those with time-limited use during young adulthood were at risk for later physical and cognitive health problems.

Variation in Alcohol Policy Enforcement Across Urban and Nonurban Communities.

PURPOSE: The goal of this study was to assess whether different types of communities (ie, urban, suburban, small town, and rural) vary in the alcohol enforcement activities they conduct. METHODS: We conducted a cross-sectional study using data from a national survey of local law enforcement agencies. DATA: The survey assessed enforcement of a range of alcohol policies at 1,082 law enforcement agencies. U.S. Census data were used to categorize agencies based on community type. RESULTS: Agencies in urban areas conducted more enforcement activities than agencies in other community types. Urban agencies were more likely than rural agencies to conduct underage compliance checks (prevalence ratio [PR]: 0.42; CI: 0.34-0.53), saturation patrols (PR: 0.80; CI: 0.67-0.95), sobriety checkpoints (PR: 0.68; CI: 0.53-0.86), and enforcement aimed at illegal sales to intoxicated patrons (PR: 0.59; CI: 0.42-0.81). Urban agencies were also more likely than small town agencies to do compliance checks (PR: 0.66; CI: 0.56-0.79) and sobriety checkpoints (PR: 0.75; CI: 0.61-0.91), and they were more likely than suburban agencies to do compliance checks (PR: 0.67; CI: 0.57-0.78) and enforcement actions around the sale of alcohol to intoxicated patrons (PR: 0.64; CI: 0.45-0.90), provision of alcohol to minors (PR: 0.77; CI: 0.65-0.92), and consumption by minors (PR: 0.90; CI: 0.82-0.99). CONCLUSIONS: Enforcement of alcohol laws differs by community type. Future research is needed to identify mechanisms to increase enforcement by agencies in different types of communities.

Effects of Restricting High Alcohol Content Beverages on Crime in California.

Background: Policy restrictions on malt liquor sales have been adopted in several cities throughout the United States in an effort to reduce crime around off-premise alcohol outlets. Although California has implemented the most restrictions on malt liquor sales, no studies in the published literature have evaluated the effects of these policies on reducing crime. Objectives: We evaluated the effectiveness of malt liquor restrictions on reducing crime around off-premise alcohol outlets in six California cities. We hypothesized that adoption of malt liquor policies would be significantly associated with decreases in crime within areas surrounding targeted outlets. Methods: We used an interrupted time-series design with control areas to examine the relationship between malt liquor policies and crime reduction. We compared crime rates three years prior and following adoption of malt liquor policies. Results: Malt liquor policies were associated with modest decreases in crime, largely Part II or less serious crimes such as simple assaults. The effectiveness of malt liquor policies varied by city, with reductions in crime greatest in Sacramento where policies were more restrictive than in other cities. Malt liquor policies were also associated with small increases in nuisance crime, especially in San Francisco. Conclusion: Results suggest that malt liquor policies may have modest effects on reducing crime when they include strong restrictions on the sale of malt liquor products. Results may be informative to other cities considering whether to maintain or change their malt liquor policies as well as cities considering placing restrictions on other high content beverages.

Effects of a federal housing voucher experiment on adolescent binge drinking: a secondary analysis of a randomized controlled trial.

AIMS: To test how a housing voucher generating residential mobility to lower-poverty neighborhoods, compared with public housing controls, influenced adolescent binge drinking, and whether gender modified effects. DESIGN: A multi-site household-level three-arm randomized trial of a housing intervention executed 1994-98, evaluated 2001-02. SETTING: Five US cities: Baltimore, MD; Boston, MA; Chicago, IL; Los Angeles, CA; and New York, NY. PARTICIPANTS: A total of 3537 adolescents in 4248 low-income eligible families were randomized; 2829 adolescents were analyzed at the interim evaluation (1950 in treatment; 879 in the control group). Attrition bias was accounted for with a 3-in-10 oversampling of hard-to-reach participants (effective response rate: 89%). INTERVENTIONS: The Moving to Opportunity (MTO) trial randomized volunteer low-income families in public housing to receive (1) rental subsidies redeemable in neighborhoods with < 10% tract poverty plus housing counseling, (2) unrestricted Section 8 rental subsidies or (3) to remain in public housing. We pooled the subsidy ('treatment') groups because they were conceptually similar and there was no evidence of statistical differences between groups on binge drinking. MEASUREMENTS: Primary outcome: past month binge drinking (five or more drinks in one sitting). FINDINGS: Adolescent binge drinking prevalence was 3.9% for treatment and 3.2% for control. The intention-to-treat (ITT) main effect of subsidy treatment (versus control) on binge drinking was non-significant, but treatment effects were different for girls and boys (treatment-gender interaction P = 0.002). MTO treatment reduced girls' binge drinking [odds ratio (OR) = 0.48, 95% confidence interval (CI) = 0.24-0.96, P = 0.037], but increased boys' binge drinking (OR = 2.37, 95% CI = 1.13-4.97, P = 0.023), compared with controls. Results were similar for secondary alcohol outcomes. Instrumental variable (IV) results adjusting for treatment compliance were comparable with ITT, but larger. CONCLUSIONS: A housing subsidy treatment that enables low-income families to move from public to private housing appears to lessen girls' binge drinking but increases boys' binge drinking, compared with controls.

Is Restricting Sales of Malt Liquor Beverages Effective in Reducing Crime in Urban Areas?

OBJECTIVE: We evaluated the effects of outlet and small area level malt liquor policies on crime in 10 U.S. cities and hypothesized that more restrictive malt liquor policies would be associated with greater reductions in crime. METHOD: We used a pooled time-series study design (i.e., panel regression) with comparison areas to test our hypothesis. Quarterly crime rates in targeted areas were compared 3 years before and after policy adoption. Four crime outcomes were analyzed: Selected Part II crimes, assaults, vandalism/property damage, and disorderly conduct. Both the presence and absence of a malt liquor policy (yes, no) and degree of restrictiveness of the malt liquor policy were assessed using a newly created measure of malt liquor policy restrictiveness developed by the investigators. Results were analyzed using a series of linear mixed models. RESULTS: Adoption of malt liquor policies was not associated with Part II selected crimes. For individual crimes (e.g., assaults, vandalism, disorderly conduct), we found mixed results as more restrictive malt liquor policies were significantly associated with decreases as well as increases in crime. In general, the evaluated policies were considered to be not highly restrictive. CONCLUSIONS: Our findings suggest that malt liquor policies at the outlet or small area level alone may not be sufficient to reduce crime associated with malt liquor use. Policies that are more restrictive or cover larger areas than assessed in the current study may be required to have an independent effect on crime outcomes.

Longitudinal Patterns of Physical Activity Among Older Adults: A Latent Transition Analysis.

Most epidemiologic studies of physical activity measure either total energy expenditure or engagement in a single type of activity, such as walking. These approaches may gloss over important nuances in activity patterns. We performed a latent transition analysis to identify patterns of activity, as well as neighborhood and individual determinants of changes in those activity patterns, over 2 years in a cohort of 2,023 older adult residents of New York, New York, surveyed between 2011 and 2013. We identified 7 latent classes: 1) mostly inactive, 2) walking, 3) exercise, 4) household activities and walking, 5) household activities and exercise, 6) gardening and household activities, and 7) gardening, household activities, and exercise. The majority of subjects retained the same activity patterns between waves (54% unchanged between waves 1 and 2, 66% unchanged between waves 2 and 3). Most latent class transitions were between classes distinguished only by 1 form of activity, and only neighborhood unemployment was consistently associated with changing between activity latent classes. Future latent transition analyses of physical activity would benefit from larger cohorts and longer follow-up periods to assess predictors of and long-term impacts of changes in activity patterns.

The Impact of Single-Container Malt Liquor Sales Restrictions on Urban Crime.

Many US cities have adopted legal restrictions on high-alcohol malt liquor sales in response to reports of crime and nuisance behaviors around retail alcohol outlets. We assessed whether these policies are effective in reducing crime in urban areas. We used a rigorous interrupted time-series design with comparison groups to examine monthly crime rates in areas surrounding alcohol outlets in the 3 years before and after adoption of malt liquor sales restrictions in two US cities. Crime rates in matched comparison areas not subject to restrictions served as covariates. Novel methods for matching target and comparison areas using virtual neighborhood audits conducted in Google Street View are described. In Minneapolis, Minnesota, sales of single containers of 16 oz or less were prohibited in individual liquor stores (n = 6). In Washington, D.C., the sale of single containers of any size were prohibited in all retail alcohol outlets within full or partial wards (n = 6). Policy adoption was associated with modest reductions in crime, particularly assaults and vandalism, in both cities. All significant outcomes were in the hypothesized direction. Our results provide evidence that retail malt liquor sales restrictions, even relatively weak ones, can have modest effects on a range of crimes. Policy success may depend on community support and concurrent restrictions on malt liquor substitutes.

Contextual Correlates of Physical Activity among Older Adults: A Neighborhood Environment-Wide Association Study (NE-WAS).

Background: Few older adults achieve recommended physical activity levels. We conducted a "neighborhood environment-wide association study (NE-WAS)" of neighborhood influences on physical activity among older adults, analogous, in a genetic context, to a genome-wide association study.Methods: Physical Activity Scale for the Elderly (PASE) and sociodemographic data were collected via telephone survey of 3,497 residents of New York City aged 65 to 75 years. Using Geographic Information Systems, we created 337 variables describing each participant's residential neighborhood's built, social, and economic context. We used survey-weighted regression models adjusting for individual-level covariates to test for associations between each neighborhood variable and (i) total PASE score, (ii) gardening activity, (iii) walking, and (iv) housework (as a negative control). We also applied two "Big Data" analytic techniques, LASSO regression, and Random Forests, to algorithmically select neighborhood variables predictive of these four physical activity measures.Results: Of all 337 measures, proportion of residents living in extreme poverty was most strongly associated with total physical activity [-0.85; (95% confidence interval, -1.14 to -0.56) PASE units per 1% increase in proportion of residents living with household incomes less than half the federal poverty line]. Only neighborhood socioeconomic status and disorder measures were associated with total activity and gardening, whereas a broader range of measures was associated with walking. As expected, no neighborhood meaZsures were associated with housework after accounting for multiple comparisons.Conclusions: This systematic approach revealed patterns in the domains of neighborhood measures associated with physical activity.Impact: The NE-WAS approach appears to be a promising exploratory technique.

Neighborhood Disorder and Physical Activity among Older Adults: A Longitudinal Study.

Neighborhood physical disorder-the visual indications of neighborhood deterioration-may inhibit outdoor physical activity, particularly among older adults. However, few previous studies of the association between neighborhood disorder and physical activity have focused on this sensitive population group, and most have been cross-sectional. We examined the relationship between neighborhood physical disorder and physical activity, measured using the Physical Activity Scale for the Elderly (PASE), in a three-wave longitudinal study of 3497 New York City residents aged 65-75 at baseline weighted to be representative of the older adult population of New York City. We used longitudinal mixed linear regression controlling for a number of individual and neighborhood factors to estimate the association of disorder with PASE score at baseline and change in PASE score over 2 years. There were too few subjects to assess the effect of changes in disorder on activity levels. In multivariable mixed regression models accounting for individual and neighborhood factors; for missing data and for loss to follow-up, each standard deviation increase in neighborhood disorder was associated with an estimated 2.0 units (95% CI 0.3, 3.6) lower PASE score at baseline, or the equivalent of about 6 min of walking per day. However, physical disorder was not related to changes in PASE score over 2 years of follow-up. In this ethnically and socioeconomically diverse population of urban older adults, residents of more disordered neighborhoods were on average less active at baseline. Physical disorder was not associated with changes in overall physical activity over time.
