Contact with the justice system can lead to a range of poor health and social outcomes. While persons of color are disproportionately represented in both the juvenile and criminal justice systems, reasons for these patters remain unclear. This study sought to examine the extent and sources of differences in arrests during adolescence and young adulthood among blacks, whites, and Hispanics in the USA. Multilevel cross-sectional logistic regression analyses were conducted using data from waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (n = 12,752 respondents). Results showed significantly higher likelihood of having ever been arrested among blacks, when compared to whites, even after controlling for a range of delinquent behaviors (odds ratio = 1.58, 95 % confidence interval = 1.27, 1.95). These black–white disparities were no longer present after accounting for racial composition of the neighborhood, supporting the growing body of research demonstrating the importance of contextual variables in driving disproportionate minority contact with the justice system.

As part of a comprehensive approach to combating the obesity epidemic, the Los Angeles County Department of Public Health launched the "Sugar Pack" health marketing campaign in fall 2011. Carried out in three stages, the campaign sought to educate and motivate the public to reduce excess calorie intake from sugar-sweetened beverage consumption. The primary Sugar Pack creative concepts provided consumers with information about the number of sugar packs contained in sugary drinks. Data from formative market research as well as lessons from previous campaigns in other U.S. jurisdictions informed the development of the materials. These materials were disseminated through a multipronged platform that included paid outdoor media on transit and billboards and messaging using social media (i.e., Twitter, Facebook, YouTube, and sendable e-cards). Initial findings from a postcampaign assessment indicate that the Sugar Pack campaign reached broadly into targeted communities, resulting in more than 515 million impressions. Lessons learned from the campaign suggest that employing health marketing to engage the public can lead to increased knowledge, favorable recognition of health messages, and self-reported intention to reduce sugar-sweetened beverage consumption, potentially complementing other obesity prevention strategies in the field.

Introduction: Tobacco policies that limit the sale of cigarettes to minors and restrict smoking in public places are important strategies to deter youth from accessing and consuming cigarettes. Methods:We examined the relationship of youth cigarette smoking status to state-level youth access and clean indoor air laws, controlling for sociodemographic characteristics and cigarette price. Data were analyzed from the 2001 to 2002 U.S. Health Behavior in School-Aged Children survey, a crosssectional survey conducted with a nationally representative sample of 13,339 students in the United States. Results:Compared with students living in states with strict regulations, those living in states with no or minimal restrictions, particularly high school students, were more likely to be daily smokers. These effects were somewhat reduced when logistic regressions were adjusted for sociodemographic characteristics and cigarette price, suggesting that higher cigarette prices may discourage youth to access and consume cigarettes independent of other tobacco control measures.Discussion: Strict tobacco control legislation could decrease the potential of youth experimenting with cigarettes or becoming daily smokers. The fi ndings are consistent with the hypothesis that smoking policies, particularly clean indoor air provisions, reduce smoking prevalence among high school students.

Although consumption of sugar-sweetened beverages (SSBs) is associated with many negative health outcomes, including obesity, diabetes, and cardiovascular disease, the relationship between consumer nutritional knowledge and the amount consumed is poorly understood. The objective of this study was to examine the relationship between knowledge of daily calorie recommendations and the amount of SSBs consumed in a large, economically and racially diverse sample of adults recruited at selected Metro subway and bus shelters in Los Angeles County. In June 2012, the Los Angeles County Department of Public Health conducted street intercept surveys to assess food attitudes and consumption behaviors and public opinions related to a recent 8-week health marketing campaign targeting SSB consumption. Descriptive and comparative analyses were conducted, including a negative binomial regression model, to examine the relationship between knowledge of the daily calorie recommendations and the amount of SSBs consumed. Among survey respondents (n = 1,041), less than one third correctly identified the daily calorie recommendations for a typical adult. After controlling for sociodemographics and weight status, respondents who correctly identified recommended calorie needs reported, on average, drinking nine fewer SSBs per month than respondents who did not. Results suggest that efforts to reduce SSB consumption might benefit from the inclusion of educational interventions that empower consumers to make healthy choices.

Objective We sought to characterize student receptivity to new menu offerings in the Los Angeles Unified School District by measuring the levels of fruit and vegetable waste after implementation of changes to the school lunch menu in fall 2011. Methods We measured waste at four randomly selected middle schools in the school district, using two sources: a) food prepared and left over after service (production waste); and b) food that was selected but not eaten by students (plate waste). Results 10.2% of fruit and 28.7% of vegetable items prepared at the four schools were left over after service. Plate waste data, collected from 2,228 students, suggest that many of them did not select fruit (31.5%) or vegetable (39.6%) items. Among students who did, many threw fruit and vegetable items away without eating a single bite. Conclusions Our findings suggest that fruit and vegetable waste was substantial and that additional work may be needed to increase student selection and consumption of fruit and vegetable offerings. Complementary interventions to increase the appeal of fruit and vegetable options may be needed to encourage student receptivity to these healthier items in the school meal program.

BACKGROUND School climate is an integral part of a comprehensive approach to improving the wellbeing of students; however, little is known about the relationships between its different domains and measures. This study examined the relationships between student, staff, and administrative measures of school climate in order to understand the extent to which they were related to each other and student outcomes. METHODS The sample included 33,572 secondary school students from 121 schools in Los Angeles County during the 2014–2015 academic year. A multilevel regression model was constructed to examine the association between the domains and measures of school climate and five outcomes of student wellbeing: depressive symptoms or suicidal ideation, tobacco use, alcohol use, marijuana use, and grades. RESULTS Student, staff, and administrative measures of school climate were weakly correlated. Strong associations were found between student outcomes and student reports of engagement and safety, while school staff reports and administrative measures of school climate showed limited associations with student outcomes. CONCLUSIONS As schools seek to measure and implement interventions aimed at improving school climate, consideration should be given to grounding these efforts in a multi-dimensional conceptualization of climate that values student perspectives and includes elements of both engagement and safety.

This study sought to examine the relationship between self-reported time and distance to the nearest retail grocery store, healthy and unhealthy food consumption, and objectively measured body mass index (BMI). We conducted a survey with 1,503 racially diverse, low-income residents at five public health centers in Los Angeles County. Most participants reported shopping at a supermarket (86.7%) and driving (59.9%) to their usual source for groceries. Over half reported living less than a mile from (58.9%) and traveling 5 min or less to reach (50.3%) the nearest grocery store. In the multivariable regression models, neither self-reported distance nor time to the nearest grocery store was consistently associated with fruit and vegetable intake, sugar-sweetened beverage consumption, or BMI. Results suggest that the need to consider access and quality as well as urban planning and transportation, when examining the relationship between the retail food environment and health outcomes.
