Impact of delaying high school start times on weight and related behaviors - the START study.

In the US, few adolescents get adequate school night sleep, largely due to early school start times. In the START study we aimed to test the following hypothesis: That following the implementation of later high school start times students have lesser longitudinal increases in body mass index (BMI) and shift to more healthful weight-related behaviors relative to students attending schools that retain early start times. The study enrolled a cohort of students (n = 2426) in five high schools in the Twin Cities, MN metro. Heights and weights were measured objectively, and surveys were administered annually from 9th through 11th grades (2016-2018). All study schools started early (either 7:30 am or 7:45 am) at baseline (2016). At follow-up 1 (2017) and continuing through follow-up 2 (2018), two schools delayed their start times by 50-65 min, while three comparison schools started at 7:30 am throughout the observation period. Using a difference-in-differences natural experiment design, we estimated differences in changes in BMI and weight-related behaviors over time between policy change and comparison schools. Students' BMIs increased in parallel in both policy change and comparison schools over time. However relative to changes in comparison schools after the start time shift, students in policy change schools had a modestly more healthful profile of weight-related behaviors - for instance they had a relatively greater probability of eating breakfast, having supper with their family, getting more activity, eating fast food less frequently, and eating vegetables daily. Later start times could be a durable, population-wide strategy that promotes healthful weight behaviors.

The impact of delayed school start time on adolescent beverage consumption, findings from the START study.

OBJECTIVES: We sought to examine the effects of high school start time delay, a proven sleep-promoting intervention, on sugary beverage (SB) consumption among U.S. adolescents. METHODS: In the Spring of 2016 (baseline), the START study recruited 2134 ninth grade students who were enrolled high schools in the Twin Cities, MN metropolitan area. These participants were surveyed again in their 10th and 11th grade years, in Spring 2017 and 2018 (follow-ups 1 and 2). All five high schools started early (7:30 or 7:45 a.m.) at baseline. By follow-up 1, two "policy change" schools shifted their start times later (8:20 or 8:50 a.m.) and maintained these later start times through follow-up 2 while three "comparison schools" retained an early start time at all time points. Generalized estimating equations using a negative binomial distribution were used to obtain estimates of the number of sugary beverages consumed per day at each wave as well as the difference in difference (DiD) estimates between baseline and each follow-up period comparing policy change to comparison schools. RESULTS: Mean baseline sugary beverage consumption was 0.9 (1.5) beverages per day in policy change schools and 1.2 (1.7) beverages per day in the comparison schools. While there was no evidence of impact of start time change on total SB consumption, DiD estimates revealed a small decrease in the number of caffeinated sugary beverages consumed between baseline and the second follow-up period in students attending the policy change schools relative to comparison schools in both crude (0.11/day reduction, p-value = 0.048) and adjusted analyses (0.11/day reduction, p-value = 0.028). CONCLUSION: Although the differences in this study were quite modest, a population-wide reduction in sugary beverage consumption could have public health benefit.

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.

School start time delays and high school educational outcomes: Evidence from the START/LEARN study.

INTRODUCTION: Delaying high school start times extends adolescents' nightly sleep, but it is less clear how it affects educational outcomes. We expect links between school start time delays and academic performance because getting enough sleep is a key input to the cognitive, health, and behavioral factors necessary for educational success. Thus, we evaluated how educational outcomes changed in the 2 years following a school start time delay. METHODS: We analyzed 2153 adolescents (51% male, 49% female; mean age 15 at baseline) from START/LEARN, a cohort study of high school students in the Minneapolis-St. Paul, MN, USA metropolitan area. Adolescents experienced either a school start time delay ("policy change schools") or consistently early school start times ("comparison schools"). We compared patterns of late arrivals, absences, behavior referrals, and grade point average (GPA) 1 year before (baseline, 2015-2016) and 2 years after (follow-up 1, 2016-2017 and follow-up 2, 2017-2018) the policy change using a difference-in-differences analysis. RESULTS: A school start time delay of 50-65 min led to three fewer late arrivals, one fewer absence, a 14% lower probability of behavior referral, and 0.07-0.17 higher GPA in policy change schools versus comparison schools. Effects were larger in the 2nd year of follow-up than in the 1st year of follow-up, and differences in absences and GPA emerged in the second year of follow-up only. CONCLUSIONS: Delaying high school start times is a promising policy intervention not only for improving sleep and health but for improving adolescents' performance in school.

Evaluation of the efficacy of an intersection conflict warning system at two-way stop-controlled rural intersections: difference-in-differences and triple-difference analytical approaches.

OBJECTIVE: Intersection conflict warning systems (ICWSs) have been implemented at high-risk two-way stop-controlled intersections to prevent right-angle crashes and associated injuries. This study involved investigation of the impacts of ICWSs on crash reductions. METHODS: The study used a quasi-experimental design to analyse the potential causal relations between Minnesota's ICWSs and various crash rate outcomes (including total, injury, non-injury, targeted right-angle and non-right-angle crashes) in pre-post analyses. A restricted randomisation method enabled identification of three controls to each ICWS treatment intersection, and included as many comparable intersection characteristics as possible. Annual crash rates (per year per intersection) were analysed over the same periods before and after system activation for treatment and control intersections in each matched group. Pre-crash data for 3 years and post-crash data for up to 5 years were included, ranging from 2010 to 2018. Negative binomial regression models with generalised estimating equations were applied to estimate the average, immediate and continuing treatment effects of ICWSs, through the difference-in-differences and difference-in-difference-in-difference approaches, respectively. RESULTS: The ICWS treatment was significantly associated with a decreasing trend for targeted right-angle crash rates posttreatment. Although not statistically significant, most crash rate outcomes appeared to be elevated immediately after treatment (statistically significant for sideswipe crashes only). Pre-post differences in average crash rates (over entire periods), except for incapacitating injury-related crashes, were not statistically significant between treatment and control intersections. CONCLUSIONS: The study provided important insight into potential causal associations between intersection safety countermeasures and crashes at high-risk rural two-way stop-controlled intersections.

Differential effectiveness of the Minnesota Safe Patient Handling Act by health care setting: An exploratory study.

BACKGROUND: The Minnesota Safe Patient Handling (MN SPH) Act requires health care facilities to implement comprehensive programs to protect their workers from musculoskeletal injuries caused by lifting and transferring patients. Nursing homes, hospitals, and outpatient facilities each face unique challenges implementing and maintaining SPH programs. The objective of the study was to compare patient handling injuries in these three health care settings and determine whether change in injury rate over time differed by setting following enactment of the law. METHODS: Workers' compensation data from a Minnesota-based insurer were used to describe worker and claim characteristics in nursing homes, hospitals, and outpatient facilities. Negative binomial models were used to compare claims and estimate mean annual patient handling claim rates by health care setting and time period following enactment of the law. RESULTS: Consistent with national data, the patient handling claim rate was highest in Minnesota nursing homes (168 claims/$100 million payroll [95% confidence interval: 163-174]) followed by hospitals (35/$100 million payroll [34-37]) and outpatient facilities (2/$100 million payroll [1.8-2.2]). Patient handling claims declined by 38% over 10 years following enactment of the law (vs. 27% for all other claims). The change in claims over time did not differ by health care setting. CONCLUSIONS: In this single-insurer sample, declines in workers' compensation claims for patient handling injuries were consistent across health care settings following enactment of a state SPH law. Though nursing homes experienced elevated claim rates overall, results suggest they are not lagging hospitals and outpatient facilities in reducing patient handling injuries.

Evaluation of the Minnesota Safe Patient Handling Act: trends in workers' compensation indemnity claims in nursing home workers before and after enactment of the law.

OBJECTIVES: The 2007 Minnesota Safe Patient Handling Act aims to protect healthcare workers from injuries caused by lifting and transferring patients. The effectiveness of the law in nursing homes is unknown. This policy evaluation measured changes in patient handling injuries before and after the law was enacted. Additionally, it assessed whether effects of the law were modified by facility levels of staffing and retention. METHODS: Workers' compensation indemnity claims for years 2005-2016 were matched to annual direct care productive hours and facility characteristics (eg, profit status, hospital affiliation and region) for all Medicaid-certified nursing homes in Minnesota. Trends in patient handling claims were analysed using negative binomial regression with generalised estimating equations. The primary predictors were time period, staff hours per resident day and staff retention. RESULTS: The patient handling indemnity claim rate declined by 25% in years 4-6 and 38% in years 7-9 following enactment of the law. Claims for all other injuries and illnesses declined by 20% in years 7-9 only. Associations between time period and patient handling claims did not vary by levels of staffing or retention. However, independent of time, facilities with annual retention ≥75% (vs <65%) had a 17% lower patient handling claim rate. CONCLUSIONS: Results suggest the law reduced patient handling claims in nursing homes. However, claim rates were elevated in facilities with low worker retention and those that were non-profit, not hospital-affiliated or in a non-metro area. Facilities with these characteristics may benefit from targeted state grants and consultation efforts.

Small food store retailers' views on healthy food retail policy in response to a local staple foods ordinance.

OBJECTIVE: Our objectives were to explore attitudes regarding food retail policy and government regulation among managers of small food stores and examine whether manager views changed due to the 2014 Minneapolis Staple Foods Ordinance, a city policy requiring retailers to stock specific healthy products. DESIGN: Manager interviewer-administered surveys were used to assess views on food retail policy four times from 2014 to 2017. We examined baseline views across manager and store and neighbourhood characteristics using cross-sectional regression analyses and examined changes over time using mixed regression models. In 2017, open-ended survey questions asked about manager insights on the Minneapolis Staple Foods Ordinance. SETTING: Minneapolis, MN, where the ordinance was enacted, and St. Paul, MN, a control community, USA. PARTICIPANTS: Managers from 147 small food retail stores. RESULTS: At baseline, 48 % of managers were likely to support a policy requiring stores to stock healthy foods/beverages, 67·5 % of managers were likely to support voluntary programmes to help retailers stock healthy foods and 23·7 % agreed government regulation of business is good/necessary. There was a significant increase in overall support for food retail policies and voluntary programmes from 2014 to 2017 (P < 0·01); however, neither increase differed by city, suggesting no differential impact from the ordinance. Minneapolis store managers reported some challenges with ordinance compliance and offered suggestions for how local government could provide support. CONCLUSIONS: Findings suggest that managers of small food retail stores are becoming increasingly amenable to healthy food policies; yet, challenges need to be addressed to ensure healthy food is available to all customers.

Store and neighborhood differences in retailer compliance with a local staple foods ordinance.

BACKGROUND: Policies to improve healthy food retail have been recognized as a potential means of reducing diet-related health disparities. The revised 2014 Minneapolis Staple Foods Ordinance instituted minimum stocking standards for healthy, staple foods. The objective of this study was to examine retailer compliance with the policy, and whether compliance varied by neighborhood and store characteristics. METHODS: In this natural experiment, audits were conducted annually pre- and post-ordinance (2014-2017) in 155 small/nontraditional stores in Minneapolis, MN and a comparison city (St. Paul, MN). Compliance measures for 10 product categories included: (1) met requirements for ≥8 categories; (2) 10-point scale (one point for each requirement met); and (3) carried any item in each category. Store characteristics included store size and ownership status. Neighborhood characteristics included census-tract socioeconomic status and low-income/low-access status. Analyses were conducted in 2018. RESULTS: All compliance measures increased in both Minneapolis and St. Paul from pre- to post-policy; Minneapolis increases were greater only for carrying any item in each category (p < 0.01). In Minneapolis, corporate (vs. independent) stores were generally more compliant. No differences were found by neighborhood characteristics. CONCLUSIONS: Overall trends suggest broad movement among Minneapolis stores towards providing a minimum level of staple foods. Increases were greater in corporate stores. Trends do not suggest neighborhood-level disparities in compliance. STUDY REGISTRATION: ClinicalTrials.gov NCT02774330, retrospectively registered May 17, 2016.

Proactive outreach tobacco treatment for socioeconomically disadvantaged smokers with serious mental illness.

Smokers with serious mental illness (SMI) face individual, interpersonal, and healthcare provider barriers to cessation treatment utilization and smoking abstinence. Proactive outreach strategies are designed to address these barriers by promoting heightened contact with smokers and facilitating access to evidence-based treatments. The present study examined the effect of proactive outreach among smokers with SMI (n = 939) who were enrolled in the publicly subsidized Minnesota Health Care Programs (MHCP) and compared this effect to that observed among MHCP smokers without SMI (n = 1382). Relative to usual care, the intervention increased treatment utilization among those with SMI (52.1% vs 40.0%, p = 0.002) and without SMI (39.3% vs 25.4%, p < 0.001). The intervention also increased prolonged smoking abstinence among those with SMI (14.9% vs 9.4%, p = 0.010) and without SMI (17.7% vs 13.6%, p = 0.09). Findings suggest that implementation of proactive outreach within publicly subsidized healthcare systems may alleviate the burden of smoking in this vulnerable population.

Occupational differences in workers' compensation indemnity claims among direct care workers in Minnesota nursing homes, 2005-2016.

BACKGROUND: Nursing assistants have one of the highest injury rates in the U.S., but few population-based studies assess differential injury risk by occupation in nursing homes. This statewide study assessed differences in musculoskeletal disorders (MSDs) and patient handling injuries among direct care workers in Minnesota nursing homes. METHODS: Indemnity claims from the Minnesota workers' compensation database were matched to time at risk from the Minnesota Nursing Home Report Card to estimate 2005 to 2016 injury and illness claim rates for certified nursing assistants (CNAs), licensed practical nurses (LPNs), and registered nurses (RNs). Associations between occupation and claim characteristics were assessed using multivariable regression modeling. RESULTS: Indemnity claim rates were 3.68, 1.38, and 0.69 per 100 full-time equivalent workers for CNAs, LPNs, and RNs, respectively. Patient handling injuries comprised 62% of claims. Compared to RNs, CNAs had higher odds of an indemnity claim resulting from an MSD (odds ratio [OR] = 1.67; 95% confidence interval [CI], 1.31-2.14) or patient handling injury (OR = 1.89; 95% CI, 1.47-2.45) as opposed to another type of injury or illness. CNAs had lower odds of receiving temporary and permanent partial disability benefits and higher odds of receiving a stipulation settlement. CONCLUSIONS: CNAs in Minnesota nursing homes are at heightened risk for lost time MSDs and patient handling injuries. Claims filed by CNAs are more frequently settled outside the regular workers' compensation benefit structure, an indication that the workers' compensation system is not providing adequate and timely benefits to these workers.

College Climate and Sexual Orientation Differences in Weight Status.

Previous research has identified significant sexual orientation disparities in obesity. Contextual factors, like lack of anti-discrimination policies and gay-straight alliances, have been shown to be associated with health outcomes like poor mental health and substance use for lesbian, gay, and bisexual (LGB) individuals moreso than their heterosexual counterparts; however, little work to date has explored the role of contextual factors on sexual orientation disparities in obesity. Individual-level, serial cross-sectional data from the 2009-2013 College Student Health Survey, which includes 2- and 4-year college students (n = 29,118) attending 46 Minnesota colleges, were used. College-level data on LGB context were primarily collected through college websites. Multinomial logistic regression models were fit to examine associations between LGB college climate scores (including non-discrimination policies, presence of LGB or diversity-related student groups, LGB courses offered, LGB housing accommodations, and prevalence of LGB students) and students' weight status (underweight, healthy weight, overweight, and obese), based on self-reported height and weight. Higher LGB climate scores (i.e., more supportive environments) were associated with lower risk of overweight and obesity among all students. Sexual orientation-stratified findings among female students suggested that the association between LGB climate scores and weight status was similar to the overall female sample. Sexual orientation-stratified findings among male students showed a more complex relationship between LGB climate scores and weight status. More work is needed to disentangle the observed associations, and to investigate other contextual factors, like state- and city-level policies, social networks and norms, and individual resiliency within these contexts to better understand the contextual influences on sexual orientation disparities in obesity.

Supportive Community Resources Are Associated with Lower Risk of Substance Use among Lesbian, Gay, Bisexual, and Questioning Adolescents in Minnesota.

Research has indicated that lesbian, gay, bisexual, and queer/questioning (LGBQ) adolescents have disproportionately high rates of substance use compared to heterosexual peers; yet certain features of schools and communities have been associated with lower substance use rates in this population. To advance this field, research examining multiple levels of influence using measures developed with youth input is needed. With community, school, and student data, this study tested hypotheses that LGBQ students attending high schools and living in communities with more LGBQ-supportive environments (assessed with a novel inventory tool) have lower odds of substance use behaviors (cigarette smoking, alcohol use, marijuana use, prescription drug misuse, and other drug use) than their peers in less supportive LGBQ environments. Multilevel models using data from 2454 LGBQ students (54.0% female, 63.9% non-Hispanic white) in 81 communities and adjusting for student and school covariates found that LGBQ adolescents who lived in areas with more community support had lower odds of frequent substance use, particularly among females. Expanding and strengthening community resources (e.g., LGBQ youth-serving organizations, LGBQ events such as a Pride parade, and LGBQ-friendly services) is recommended to further support LGBQ adolescents and reduce substance use disparities.

Evaluation of the first U.S. staple foods ordinance: impact on nutritional quality of food store offerings, customer purchases and home food environments.

BACKGROUND: Many lower-income and racially diverse communities in the U.S. have limited access to healthy foods, with few supermarkets and many small convenience stores, which tend to stock limited quantities and varieties of healthy foods. To address food access, in 2015 the Minneapolis Staple Foods Ordinance became the first policy requiring food stores to stock minimum quantities and varieties of 10 categories of healthy foods/beverages, including fruits, vegetables, whole grains and other staples, through licensing. This study examined whether: (a) stores complied, (b) overall healthfulness of store environments improved, (c) healthy customer purchases increased, and (d) healthfulness of home food environments improved among frequent small store shoppers. METHODS: Data for this natural (or quasi) experiment were collected at four times: pre-policy (2014), implementation only (no enforcement, 2015), enforcement initiation (2016) and continued monitoring (2017). In-person store assessments were conducted to evaluate food availability, price, quality, marketing and placement in randomly sampled food retailers in Minneapolis (n = 84) and compared to those in a nearby control city, St. Paul, Minnesota (n = 71). Stores were excluded that were: supermarkets, authorized through WIC (Special Supplemental Nutrition Program for Women, Infants, and Children), and specialty stores (e.g., spice shops). Customer intercept interviews were conducted with 3,039 customers exiting stores. Home visits, including administration of home food inventories, were conducted with a sub-sample of frequent shoppers (n = 88). RESULTS: Overall, findings indicated significant improvements in healthy food offerings by retailers over time in both Minneapolis and St. Paul, with no significant differences in change between the two cities. Compliance was low; in 2017 only 10% of Minneapolis retailers in the sample were fully compliant, and 51% of participating Minneapolis retailers met at least 8 of the 10 required standards. Few changes were observed in the healthfulness of customer purchases or the healthfulness of home food environments among frequent shoppers, and changes were not different between cities. CONCLUSIONS: This study is the first evaluation a local staple foods ordinance in the U.S. and reflects the challenges and time required for implementing such policies.

Variation in the food environment of small and non-traditional stores across racial segregation and corporate status.

OBJECTIVE: We examined differences in consumer-level characteristics and structural resources and capabilities of small and non-traditional food retailers (i.e. corner stores, gas-marts, pharmacies, dollar stores) by racial segregation of store neighbourhood and corporate status (corporate/franchise- v. independently owned). DESIGN: Observational store assessments and manager surveys were used to examine availability-, affordability- and marketing-related characteristics experienced by consumers as well as store resources (e.g. access to distributors) and perceived capabilities for healthful changes (e.g. reduce pricing on healthy foods). Cross-sectional regression analyses of store and manager data based on neighbourhood segregation and store corporate status were conducted. SETTING: Small and non-traditional food stores in Minneapolis and St. Paul, MN, USA.ParticipantsOne hundred and thirty-nine stores; seventy-eight managers. RESULTS: Several consumer- and structural-level differences occurred by corporate status, independent of residential segregation. Compared with independently owned stores, corporate/franchise-owned stores were more likely to: not offer fresh produce; when offered, receive produce via direct delivery and charge higher prices; promote unhealthier consumer purchases; and have managers that perceived greater difficulty in making healthful changes (P≤0·05). Only two significant differences were identified by residential racial segregation. Stores in predominantly people of colour communities (<30 % non-Hispanic White) had less availability of fresh fruit and less promotion of unhealthy impulse buys relative to stores in predominantly White communities (P≤0·05). CONCLUSIONS: Corporate status appears to be a relevant determinant of the consumer-level food environment of small and non-traditional stores. Policies and interventions aimed at making these settings healthier may need to consider multiple social determinants to enable successful implementation.

Correlates of short sleep duration among adolescents.

INTRODUCTION: Short sleep duration is exceedingly common among adolescents and has implications for healthy youth development. We sought to document associations between adolescents' sleep duration and characteristics of their schedules, behaviors, and wellbeing. METHODS: We used data from the baseline wave (9th grade year) of the START study, a cohort of 2134 students in five Minnesota high schools to assess how self-reported sleep duration was associated with the prevalence of time-use characteristics (i.e. activity schedules, screen use), sleep-wake problems (i.e. trouble waking in the morning, falling asleep in class, etc.), and risk of depression. RESULTS: Shorter sleep duration was associated with various behaviors including greater computer/screen time and screen use after bed, a lower probability of doing homework, participation in sports doing chores on school nights, and reporting that it takes at least 20 min to fall asleep on school days (p < 0.05). Suboptimal sleep duration was also associated with a higher probability of all reported sleep-wake problems as well as higher risk of depressive symptoms (p < 0.05). CONCLUSIONS: Given that getting an optimal amount of sleep can protect youth from risk and promote healthy youth development, it is critical that we gain a greater understanding of correlates and consequences of short sleep duration in order to develop a sleep-friendly culture for youth.

Association between store food environment and customer purchases in small grocery stores, gas-marts, pharmacies and dollar stores.

BACKGROUND: Purchases at small/non-traditional food stores tend to have poor nutritional quality, and have been associated with poor health outcomes, including increased obesity risk The purpose of this study was to examine whether customers who shop at small/non-traditional food stores with more health promoting features make healthier purchases. METHODS: In a cross-sectional design, data collectors assessed store features in a sample of 99 small and non-traditional food stores not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Minneapolis/St. Paul, MN in 2014. Customer intercept interviews (n = 594) collected purchase data from a bag check and demographics from a survey. Store measures included fruit/vegetable and whole grain availability, an overall Healthy Food Supply Score (HFSS), healthy food advertisements and in-store placement, and shelf space of key items. Customer nutritional measures were analyzed using Nutrient Databases System for Research (NDSR), and included the purchase of ≥1 serving of fruits/vegetables; ≥1 serving of whole grains; and overall Healthy Eating Index-2010 (HEI-2010) score for foods/beverages purchased. Associations between store and customer measures were estimated in multilevel linear and logistic regression models, controlling for customer characteristics and store type. RESULTS: Few customers purchased fruits and vegetables (8%) or whole grains (8%). In fully adjusted models, purchase HEI-2010 scores were associated with fruit/vegetable shelf space (p = 0.002) and the ratio of shelf space devoted to healthy vs. less healthy items (p = 0.0002). Offering ≥14 varieties of fruit/vegetables was associated with produce purchases (OR 3.9, 95% CI 1.2-12.3), as was having produce visible from the store entrance (OR 2.3 95% CI 1.0 to 5.8), but whole grain availability measures were not associated with whole grain purchases. CONCLUSIONS: Strategies addressing both customer demand and the availability of healthy food may be necessary to improve customer purchases. TRIAL REGISTRATION: ClinialTrials.gov: NCT02774330 .

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.

Food and beverage purchases in corner stores, gas-marts, pharmacies and dollar stores.

OBJECTIVE: Little is known about customer purchases of foods and beverages from small and non-traditional food retailers (i.e. corner stores, gas-marts, dollar stores and pharmacies). The present study aimed to: (i) describe customer characteristics, shopping frequency and reasons for shopping at small and non-traditional food retailers; and (ii) describe food/beverage purchases and their nutritional quality, including differences across store type. DESIGN: Data were collected through customer intercept interviews. Nutritional quality of food/beverage purchases was analysed; a Healthy Eating Index-2010 (HEI-2010) score for purchases was created by aggregating participant purchases at each store. SETTING: Small and non-traditional food stores that were not WIC-authorized in Minneapolis and St. Paul, MN, USA. SUBJECTS: Customers (n 661) from 105 food retailers. RESULTS: Among participants, 29 % shopped at the store at least once daily; an additional 44 % shopped there at least once weekly. Most participants (74 %) cited convenient location as the primary draw to the store. Customers purchased a median of 2262 kJ (540 kcal), which varied by store type (P=0·04). The amount of added sugar far surpassed national dietary recommendations. At dollar stores, participants purchased a median of 5302 kJ (1266 kcal) for a median value of $US 2·89. Sugar-sweetened beverages were the most common purchase. The mean HEI-2010 score across all stores was 36·4. CONCLUSIONS: Small and non-traditional food stores contribute to the urban food environment. Given the poor nutritional quality of purchases, findings support the need for interventions that address customer decision making in these stores.

Can Obviously Intoxicated Patrons Still Easily Buy Alcohol at On-Premise Establishments?

BACKGROUND: Excessive alcohol consumption at licensed alcohol establishments (i.e., bars and restaurants) has been directly linked to alcohol-related problems such as traffic crashes and violence. Historically, alcohol establishments have had a high likelihood of selling alcohol to obviously intoxicated patrons (also referred to as "overservice") despite laws prohibiting these sales. Given the risks associated with overservice and the need for up-to-date data, it is critical that we monitor the likelihood of sales to obviously intoxicated patrons. METHODS: To assess the current likelihood of a licensed alcohol establishment selling alcohol to an obviously intoxicated patron, we conducted pseudo-intoxicated purchase attempts (i.e., actors attempt to purchase alcohol while acting out obvious signs of intoxication) at 340 establishments in 1 Midwestern metropolitan area. We also measured characteristics of the establishments, the pseudo-intoxicated patrons, the servers, the managers, and the neighborhoods to assess whether these characteristics were associated with likelihood of sales of obviously intoxicated patrons. We assessed these associations with bivariate and multivariate regression models. RESULTS: Pseudo-intoxicated buyers were able to purchase alcohol at 82% of the establishments. In the fully adjusted multivariate regression model, only 1 of the characteristics we assessed was significantly associated with likelihood of selling to intoxicated patrons-establishments owned by a corporate entity had 3.6 greater odds of selling alcohol to a pseudo-intoxicated buyer compared to independently owned establishments. CONCLUSIONS: Given the risks associated with overservice of alcohol, more resources should be devoted first to identify effective interventions for decreasing overservice of alcohol and then to educate practitioners who are working in their communities to address this public health problem.
