Collision tumor: Multinodular and vacuolating neuronal tumor with isocitrate dehydrogenase-mutant diffuse astrocytoma.

Herein, we report a case of a collision tumor involving a multinodular and vacuolating neuronal tumor (MVNT) and a diffuse astrocytoma. A collision tumor between these two entities has not previously been reported. The patient is a 35-year-old woman who presented with new-onset hearing loss and ringing in her right ear. Magnetic resonance imaging identified a non-enhancing mass involving the gray matter and subcortical white matter of the left middle frontal gyrus. Additionally, tiny clustered nodules were noted along the underlying subcortical ribbon and superficial subcortical white matter of the left superior frontal gyrus. The patient underwent a left frontal craniotomy and complete resection of the mass. Histologic examination of the resected specimen demonstrated a collision tumor consisting of a diffuse astrocytoma (isocitrate dehydrogenase [IDH] mutant, central nervous system [CNS] World Health Organization [WHO] grade 2) and an MVNT, with the latter demonstrating characteristic morphologic and immunohistochemical features.

Healthcare social network research and the ECHO model™: Exploring a community of practice to support cultural brokers and transfer cultural knowledge.

BACKGROUND: Project ECHO® networks at Children's Health Queensland Hospital and Health Service (CHQHHS) are communities of practice designed to mitigate services and systems fragmentation by building collaborative partnerships addressing priority child and youth health needs. Aboriginal and Torres Strait Islander people experience the negative impacts of fragmentation in addition to historical challenges of absent or culturally inappropriate health services. Access to culturally safe and responsive services can be improved by engaging Aboriginal and Torres Strait Islander Health Workers and similar roles in an online community of practice, supporting the integration of cultural and clinical knowledge and self-determination of Aboriginal and Torres Strait Islander consumers in decisions affecting their health. Analysing professional support networks and knowledge sharing patterns helps identify enablers and barriers to partnerships. Using social network research, the multilevel network inclusive of ECHO network members and their colleagues was studied to identify interdisciplinary and cross-sector advice exchange patterns, explore the position of cultural brokers and identify common relational tendencies. METHODS: Social network theories and methods informed the collection of network data and analysis of advice-seeking relationships among ECHO network members and their nominees. Registered members from two ECHO networks were invited to complete the Qualtrics survey. Networks analysed comprised 398 professionals from mainstream health, Aboriginal and Torres Strait Islander Community Controlled Health Organisation, education, disability and child safety service settings. RESULTS: Brokers were well represented, both those who hold knowledge brokerage positions as well as cultural brokers who incorporate clinical and cultural knowledge enabling holistic care for Aboriginal and Torres Strait Islander patients (38 individuals, 17% of network). Professionals who occupy brokerage positions outside the ECHO network tend to be more connected with co-members within the network. CONCLUSIONS: This study is the first application of contemporary social network theories and methods to investigate an ECHO network. The findings highlight the connectivity afforded by brokers, enabling the coordination and collaboration necessary for effective care integration. Inclusion of cultural brokers in an ECHO network provides sustained peer group support while also cultivating relationships that facilitate the integration of cultural and clinical knowledge.

Experiences of Racial Discrimination and Periconceptional Diet Quality.

BACKGROUND: Racism is a key determinant of perinatal health disparities. Poor diet may contribute to this effect, but research on racism and dietary patterns is limited. OBJECTIVE: We aimed to describe the relation between experiences of racial discrimination and adherence to the 2015‒2020 Dietary Guidelines for Americans. METHODS: We used data from a prospective pregnancy cohort study conducted at 8 United States medical centers (2010‒2013). At 6‒13 weeks of gestation, 10,038 nulliparous people with singleton pregnancies were enrolled. Participants completed a Block food frequency questionnaire, assessing usual diet in the 3 mo around conception, and the Krieger Experiences of Discrimination Scale, assessing the number of situational domains (e.g., at school and on the street) in which participants ever experienced racial discrimination. Alignment of dietary intake with the 2015-2020 Dietary Guidelines for Americans was assessed using the Healthy Eating Index (HEI)-2015. RESULTS: The study showed that 49%, 44%, 35%, and 17% of the Asian, Black, Hispanic, and White participants reported experiences of racial discrimination in any domain. Most participants experienced discrimination in 1 or 2 situational domains. There were no meaningful differences in HEI-2015 total or component scores in any racial or ethnic group according to count of self-reported domains in which individuals experienced discrimination. For example, mean total scores were 57‒59 among Black, 61‒66 among White, 61‒63 among Hispanic, and 66‒69 among Asian participants across the count of racial discrimination domains. CONCLUSIONS: This null association stresses the importance of going beyond interpersonal racial discrimination to consider the institutions, systems, and practices affecting racialized people to eliminate persistent inequalities in diet and perinatal health.

Changes in cancer incidence and survival among Aboriginal and Torres Strait Islander children in Australia, 1997-2016.

BACKGROUND: This study reports cancer incidence and survival among Aboriginal and Torres Strait Islander children and other Australian children, and assesses changes over time. PROCEDURE: Data were from the population-based Australian Childhood Cancer Registry. The study comprised children aged under 15 diagnosed between 1997 and 2016 and with mortality follow-up until 31 December 2017. Incidence trends were analysed using JoinPoint regression. Five-year cancer-specific survival was calculated using the semi-complete approach with survival comparisons made using multivariable flexible parametric models. RESULTS: Aboriginal and Torres Strait Islander children accounted for 506 of 13,299 eligible cases (3.8%). Incidence rates for Aboriginal and Torres Strait Islander children across the study period increased by 2.3% annually (95% confidence interval [CI]: +0.6% to +4.0%) and for other Australian children increased by 0.6% annually (95% CI: +0.3% to +0.9%; p = .05). Nonetheless, cancer incidence was consistently lower for Aboriginal and Torres Strait Islander children, with an incidence rate ratio of 0.73 (95% CI: 0.62-0.85; p < .01) between 2012 and 2016. Survival for Aboriginal and Torres Strait Islander children with solid tumours was 70.6% (95% CI: 62.5%-77.3%) and for other Australian children was 83.5% (95% CI: 82.3%-84.7%; p < .01), with indications of this difference diminishing in recent years. CONCLUSIONS: Improvements in identification, particularly in urban areas, most likely accounts for the greater increase in cancer incidence rates among Aboriginal and Torres Strait Islander children. Examination of data on stage at diagnosis and treatment may provide important insights into survival for children with solid tumours.

An embedded multiple case study: using CFIR to map clinical food security screening constructs for the development of primary care practice guidelines.

BACKGROUND: Food insecurity (FI), the limited access to healthy food to live an active and healthy life, is a social determinant of health linked to poor dietary health and difficulty with disease management in the United States (U.S.). Healthcare experts support the adoption of validated screening tools within primary care practice to identify and connect FI patients to healthy and affordable food resources. Yet, a lack of standard practices limits uptake. The purpose of this study was to understand program processes and outcomes of primary care focused FI screening initiatives that may guide wide-scale program implementation. METHODS: This was an embedded multiple case study of two primary care-focused initiatives implemented in two diverse health systems in Chicago and Suburban Cook County that routinely screened patients for FI and referred them to onsite food assistance programs. The Consolidated Framework for Implementation Research and an iterative process were used to collect/analyze qualitative data through semi-structured interviews with N = 19 healthcare staff. Intended program activities, outcomes, actors, implementation barriers/facilitators and overarching implementation themes were identified as a part of a cross-case analysis. RESULTS: Programs outcomes included: the number of patients screened, identified as FI and that participated in the onsite food assistance program. Study participants reported limited internal resources as implementation barriers for program activities. The implementation climate that leveraged the strength of community collaborations and aligned internal, implementation climate were critical facilitators that contributed to the flexibility of program activities that were tailored to fill gaps in resources and meet patient and clinician needs. CONCLUSION: Highly adaptable programs and the healthcare context enhanced implementation feasibility across settings. These characteristics can support program uptake in other settings, but should be used with caution to preserve program fidelity. A foundational model for the development and testing of standard clinical practice was the product of this study.

Developmental disparities in sedentary time by period of the day among US youth: a cross-sectional study.

BACKGROUND: Definitive evidence shows sedentary time (ST) is an independent risk factor for chronic disease, irrespective of physical activity. Despite calls to limit youth ST, studies demonstrate a spike in ST at the transition from childhood to adolescence. Identifying periods of the day (e.g., before school, during school, afterschool, and evenings) during which ST is higher in adolescents vs. children-that is, specifying when within daily routines ST disparities emerge-may be important to inform intervention strategies, as periods of the day correspond with variations in setting and supervision. The purpose of this study was to examine device-assessed ST engagement by period of day and developmental stage in a nationally representative sample of United States youth. METHODS: Youth (N = 2,972 between 6-18 years) from the 2003-2004 and 2005-2006 waves of NHANES reported demographic variables and wore an accelerometer for seven consecutive days to determine ST. Linear regression analyses were applied to study associations between ST and developmental stage (childhood or adolescence) by period of the week and weekend days, while controlling for sex, race/ethnicity, annual family income, and body mass index. RESULTS: Adjusted linear regressions (p-values < 0.0001) showed that adolescents were more sedentary than children during school, afterschool, and weekday evening periods as well as all the weekend periods. However, during school (36.3 ± 7.3 vs. 28.2 ± 7.2 min/hour; b = -7.4 [-8.1, -6.6]) and afterschool periods (31.1 ± 7.7 vs. 22.7 ± 7.0 min/hour; b = -7.8 [-8.6, -7.0]) showed the largest weekly ST disparities by developmental stage. Overall, the during school and after school hours constitute most (during school = 35% and afterschool = 16%) of the weekly ST disparity between children and adolescents. CONCLUSIONS: Our data provide interventionists with estimates of the potential for ST reduction in each setting and period of the day among US adolescents. Future research should gather information about the barriers and facilitators of ST in adolescents by period of the day to help understand factors driving disparities.

Pilot study of a culturally sensitive intervention to promote genetic counseling for breast cancer risk.

BACKGROUND: Despite the benefits of genetic counseling and testing, uptake of cancer genetic services is generally low and Black/African American (Black) women are substantially less likely to receive genetic services than non-Hispanic White women. Our team developed a culturally sensitive, narrative decision aid video to promote uptake of genetic counseling among Black women at risk for a hereditary breast cancer syndrome that can be incorporated in conjunction with population-based cancer risk assessment in a clinical setting. We report here a pilot study to demonstrate changes in intention to access genetic counseling and intervention satisfaction. METHODS: Black women who were personally unaffected by breast cancer and were recommended for genetic counseling based on family history screening in a mammography center were recruited at the time of the mammogram. A prospective, pre-post survey study design, guided by theoretical constructs, was used to evaluate baseline and immediate post-intervention psychosocial factors, including intention to participate in genetic counseling and intervention satisfaction. RESULTS: Pilot recruitment goals were met (n = 30). Pre-intervention, 50% of participants indicated that they were extremely likely to make a genetic counseling appointment, compared with 70% post-intervention (p = 0.05). After watching the intervention, 50% of participants indicated that the video changed their mind regarding genetic counseling. CONCLUSIONS: This study demonstrated cultural satisfaction with a decision aid intervention designed to motivate Black women with hereditary breast cancer risk to attend a genetic counseling appointment. Our study showed that intention may be a specific and key construct to target in interventions designed to support decision-making about genetic services. Study results informed the design of a subsequent large scale, randomized implementation study. TRIAL REGISTRATION: Trial registration: Clinicaltrials.gov NCT04082117 . Registered September 9, 2019. Retrospectively registered.

Development of a culturally sensitive narrative intervention to promote genetic counseling among African American women at risk for hereditary breast cancer.

BACKGROUND: African American women with hereditary breast cancer risk are less likely to undergo genetic counseling and testing compared with non-Hispanic White women. Inequities in the use of precision cancer care are likely to exacerbate racial disparities in cancer outcomes. A culturally sensitive multimedia narrative intervention was developed to motivate African American women at risk for hereditary breast cancer to engage in genetic counseling. METHODS: Development of the intervention was grounded in the Integrative Model of Behavioral Prediction using a phenomenological, deductive approach and employed multiple qualitative methods for data collection, including 1-on-1 interviews and story circles with members of the target audience to identify salient themes and lived experiences. Focus group testing was then conducted with members of the group of focus, primary care providers, and community stakeholders. RESULTS: Six themes that mapped to the theoretical model were identified. Lived experiences were abstracted from story circle data to create a narrative storyline. Educational content and motivational messaging derived from the 6 themes were embedded into the script. Focus group testing with stakeholder groups was used to refine the intervention. Testing of the final multimedia narrative with focus groups indicated that the intervention was culturally sensitive and authentic, and the messaging was effective. CONCLUSIONS: Multiple qualitative data collection methods and a robust theoretical framework of health behavior were key elements for this study to develop a culturally sensitive, narrative intervention that reflects lived experiences and motivates underserved African American women with hereditary breast cancer risk to engage in genetic counseling. This strategy can be applied to mitigate racial inequities in the use of other genomic approaches for personalizing cancer care.

Did Playground Renovations Equitably Benefit Neighborhoods in Chicago?

Between 2013 and 2016, the Chicago Park District renovated 327 playgrounds in need of repair across Chicago through a $44 million investment. This study evaluated whether short-term and longer-term impacts of renovations on park use and park-based moderate-to-vigorous physical activity (MVPA) differed by neighborhood income level and neighborhood concentration of Black residents. A total of 39 parks with renovated playgrounds and 39 matched comparison parks with playgrounds that needed repair but not selected for renovation in year 1 were studied. Three waves of observational data were collected at each park: baseline, 12 months post-renovation, and 24 months post-renovation. Difference-in-differences mixed-effects Poisson regression models estimated renovation effects. The effects of renovations differed by the income level and concentration of Black residents in the neighborhoods where parks were located. In low-income neighborhoods, renovations were associated with reductions in park use and park-based MVPA over the longer term. In contrast, renovations were associated with short- and longer-term increases in park use and park-based MVPA in medium-income neighborhoods and with longer-term increases in MVPA in high-income neighborhoods. Renovations were generally not associated with any changes in park use or park-based MVPA in high-percent Black neighborhoods, but they were associated with increased park use and park-based MVPA in low-percent Black neighborhoods. This study suggests playground renovations in Chicago may have had unintended consequences, increasing neighborhood income and racial disparities in park use and park-based MVPA. Future playground renovation efforts may need to allocate more resources for renovating the broader park where in disrepair, more intensely involve neighborhood residents, and employ complementary strategies such as additional park programming to ensure renovations benefit all neighborhoods.

Gender and racial/ethnic differences in food selectivity in children with intellectual disabilities.

BACKGROUND: We examined differences in food selectivity by gender and parent race/ethnicity in children with intellectual disabilities. METHOD: A convenience sample of 56 children with intellectual disabilities was analysed. A modified Youth/Adolescent Food Frequency Questionnaire and a 3-day food record were used to measure child food refusal rate and food repertoire, respectively. RESULTS: Boys were about twice as likely to refuse total foods (rate ratio = 2.34, 95%CI = 1.34-4.09) and fruits (rate ratio = 2.03, 95%CI = 1.04-3.95) and 54% more likely to refuse vegetables (rate ratio = 1.54, 95%CI = 0.93-2.54). Children with Hispanic parents were twice as likely to refuse vegetables compared to children with non-Hispanic White parents (rate ratio = 2.00, 95%CI = 1.03-3.90). In analyses stratified by the presence or absence of co-occurring probable autism spectrum disorder, boys had greater food selectivity than girls. CONCLUSIONS: This study expands our understanding of food selectivity in children with intellectual disabilities.

Invited Commentary: Learning From Our Past to Build on Our Future- Lessons Learned From MRFIT and JUMBO.

We propose that Blackburn (Am J Epidemiol. 2020;189(6):491-498) ignores several important issues that need to be considered in the context of a historical reflection of the National Heart Institute's landmark study, the Multiple Risk Factor Intervention Trial (MRFIT), and the alternative proposal, the "JUMBO" trial, submitted to the National Heart Institute by an experienced team of extramural investigators but never funded. A key focus of this commentary is to offer an alternative perspective on both studies using our current understanding of the impact of social and structural determinants of health; evidence that policy, systems, and environmental interventions are needed to support behavior change at the individual level; and the significance of examining research from a racial/socioeconomic equity lens. While we strongly agree with Blackburn's conclusion urging the National Institutes of Health to invest in prevention research at a level consistent with its social and economic impact, we encourage the author to move beyond simply underscoring the methodological limitations and failure of the findings of MRFIT compared with the potential of the proposed JUMBO trial to consider the contribution of MRFIT to our current understanding of chronic disease prevention and treatment.

A Step toward Understanding Diet Quality in Urban African-American Breast Cancer Survivors: A Cross-sectional Analysis of Baseline Data from the Moving Forward Study.

PURPOSE: Little is known about the dietary behaviors of African-American breast cancer survivors (AABCS). We sought to describe dietary intake and quality in AABCS and examine associations with demographic, social, lifestyle, and body composition factors to potentially inform the development of effective dietary interventions. METHODS: Baseline data from a prospective weight loss trial of 210 AABCS were assessed. A food frequency questionnaire was used to evaluate dietary intake and diet quality via the Healthy Eating Index 2010 (HEI-2010) and Alternative Healthy Eating Index 2010 (AHEI-2010). Linear regression analysis was conducted to determine the most influential variables on diet quality. RESULTS: Mean HEI- and AHEI-2010 total scores were 65.11 and 56.83 indicating that diet quality needs improvement. Women were the least adherent to recommendations for intake of whole grains, dairy, sodium, empty calories, sugary beverages, red/processed meats, and trans-fat. Increased self-efficacy for healthy eating behaviors, more years of education (AHEI only), negative smoking status, smaller waist circumference, and increased physical activity (HEI only) were significantly associated with higher diet quality scores. CONCLUSION: Our findings suggest the diet quality of AABCS needs improvement. Intervention programs may achieve higher diet quality in AABCS by focusing on increasing self-efficacy for healthy eating behaviors.

Understanding the factors influencing low-income caregivers' perceived value of a federal nutrition programme, the Special Supplemental Nutrition Program for Women, Infants and Children (WIC).

OBJECTIVE: Retention of participants has been an issue in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). It has been suggested that the perceived value of WIC may affect whether participants remain in the programme. The present study aimed to explore this phenomenon. DESIGN: Using a constructivist approach, thirty-one individual in-depth interviews were conducted. Transcripts were analysed using constant comparative analysis. Social, cultural and environmental factors that contribute to the value of WIC were explored as the phenomenon of interest. SETTING: Eight WIC clinics across the State of Illinois, USA.ParticipantsThirty-one caregivers of children enrolled in WIC for at least 6 months. RESULTS: Several factors influenced perceived value of WIC at the interpersonal (level of social support), clinic (value of WIC services v. programme administration issues), vendor (shopping difficulties), community and systems levels (other programme use, stigma and restrictions on food choice). Other themes existed along continua, which overlapped several levels (continuum of perceived need and perceived value of infant formula). CONCLUSIONS: Many caregivers value WIC, especially before their child turns 1 year old. Improvements are needed at the clinic, during shopping and within the food packages themselves in order to increase perceived value of WIC.

Primary Care Women's Health Screening: A Case Study of a Community Engaged Human Centered Design Approach to Enhancing the Screening Process.

PURPOSE: To apply a Human Centered Design (HCD) approach to co-designing a comprehensive women's health screening tool with community partners. DESCRIPTION: Evidenced-based health screenings for behaviors and risks are important tools in primary health care and disease prevention, especially for women. However, numerous barriers limit the effective implementation of comprehensive health screenings, and often lead to excluding important risks such as intimate partner violence (IPV). Utilizing a human centered design approach (HCD), Mountain Area Health Education Center (MAHEC, NC USA) developed a community co-designed 9-topic health screening for women. Key end-users were recruited to participate in the design process, including women who identified IPV as a health issue in their community, Spanish speaking women, domestic violence program organizers, and MAHEC staff. ASSESSMENT: A total of 21 participants collaborated during three design sessions on two specific goals: 1) creating a comprehensive women's health screening tool from the existing tools that were in use in our clinics at the time, and 2) incorporating IPV screening. Through the HCD sessions, participants highlighted the impact of what they termed "Triple T: time, trust and talk" on the effectiveness of women's health screening. CONCLUSION: Our co-designed women's health screening tool is a first step towards addressing screening barriers from both primary care provider's and community women's perspectives. Future research will explore the facilitators of and barriers to implementing the tools in different primary care settings. Future work should also more systematically examine whether and how screening processes may reinforce or contribute to women's feelings of being stereotyped, and how screening processes can be designed to avoid stereotype threat, which has the potential to reduce the effectiveness of screenings intended to promote women's health.

The relationship between home- and individual-level diet quality among African American and Hispanic/Latino households with young children.

BACKGROUND: The quality of most Americans' diets is far from optimal. Given that many Americans consume a significant portion of calories in the home, intervening in this setting could be beneficial. However, the relationship between the home food environment and diet quality is not well understood. This study examined the relationship between diet quality at the individual level with home-level diet quality using an index that measures compliance with federal dietary guidance. METHODS: This was a cross sectional study that enrolled 97 African American and Hispanic/Latino low-income parent-child dyads. Diet quality at the individual level was assessed through two 24-h dietary recalls collected for parents and children, respectively. Diet quality at the home level was assessed with two home food inventories conducted in participants' homes. Diet quality scores at the home and individual levels were computed by applying the Healthy Eating Index-2010 (HEI-2010) to these data. Linear models adjusted for potential confounding factors were used to examine the relationship between diet quality at the home and individual levels. RESULTS: Total HEI-2010 scores from parents and children's diets were positively associated with HEI-2010 scores based on home food inventories (parent diet: ß: 0.36, 95% CI: 012-0.60; child diet: 0.38 95% CI: 013-0.62). Positive associations were also observed between individual level and home level subcomponent HEI-2010 scores for total fruit (parent: 0.55 95% CI: 0.16-0.94; child: 0.49 95% CI: 0.03-0.94), whole fruit (parent only: 0.41 95% CI: 0.07-0.74), greens and beans (parent only: 0.39 95% CI: 0.05-0.74), and whole grain (children only: 0.33 95% CI: 0.04-0.63). CONCLUSION: This study demonstrated that individual level diet quality was positively associated with home-level diet quality. Findings from this study can help us to address modifiable targets of intervention in the home to improve diet quality.

Barriers to fruit and vegetable consumption among farmers' market incentive programme users in Illinois, USA.

OBJECTIVE: Previous research indicates that low-income individuals often struggle to consume the recommended amount of fruits and vegetables (F&V). LINK Up Illinois is a farmers' market incentive programme that aims to increase F&V consumption among Supplemental Nutrition Assistance Program (SNAP) recipients by improving access to and affordability of locally grown foods. The present research aimed to identify barriers to F&V consumption that exist among users of the LINK Up Illinois programme. DESIGN: Cross-sectional. SETTING: Farmers' markets in Chicago, Springfield, Northbrook, Woodstock, Aurora and Urbana, IL. SUBJECTS: In 2016, a volunteer sample of 140 LINK Up Illinois users (mean age 42·5 years; 81·7 % female; 28·7 % African American; 44·0 % obese) completed a survey at participating farmers' markets across the state. Information on demographics, food shopping behaviours, programme satisfaction, barriers to F&V consumption and frequency of F&V consumption was collected and examined. RESULTS: Approximately 23 % of survey participants reported consuming F&V ≥3 times/d. The barriers to F&V consumption most often reported by survey participants were the cost of F&V (29·5 %), spoilage (18·6 %), knowing how to cook F&V (8·7 %) and not thinking about F&V when hungry (8·6 %). Results from multivariable-adjusted logistic regression models suggested that reporting one or more barriers was associated with reduced odds of consuming vegetables ≥3 times/d, but not fruits. CONCLUSIONS: Cost, spoilage and knowledge of cooking are key barriers to F&V consumption that exist among LINK Up Illinois users. Strategies are needed to mitigate these barriers and increase F&V consumption in this population.

Examining the Impact of Structural Racism on Food Insecurity: Implications for Addressing Racial/Ethnic Disparities.

Food insecurity is defined as "a household-level economic and social condition of limited or uncertain access to adequate food." While, levels of food insecurity in the United States have fluctuated over the past 20 years; disparities in food insecurity rates between people of color and whites have continued to persist. There is growing recognition that discrimination and structural racism are key contributors to disparities in health behaviors and outcomes. Although several promising practices to reduce food insecurity have emerged, approaches that address structural racism and discrimination may have important implications for alleviating racial/ethnic disparities in food insecurity and promoting health equity overall.

Sex, Race, Food Security, and Sugar Consumption Change Efficacy Among Low-Income Parents in an Urban Primary Care Setting.

The purpose of this study was to examine relationships between food security and parents' self-efficacy to reduce consumption of sugar-sweetened beverages and sugary snacks in a sample of parents in waiting rooms in community-based primary care clinics in West Tennessee. Results from logistic regression models underscore the need for nuanced analysis, as the results from the pooled regression models differ from those stratified by food security status. Self-efficacy is an important factor for behavior change, and our study highlights the need for additional research examining how social, psychological, and behavioral factors have implications for behavior change self-efficacy.

Health Behavior and Weight Changes Among Ethnic and Racial Minority Preschoolers and Their Parents: Associations Across 1 Year.

OBJECTIVE: To determine whether parent health behavior changes and feeding practices were associated with child changes in body mass index z-score and related health behaviors over the course of 1 year. METHODS: Anthropometric data from 590 child-parent dyads of ethnic/racial minority groups were collected at baseline, 14 weeks (postintervention), and 1-year follow-up. Additionally, parent screen time and feeding practices and child dietary consumption, diet quality, physical activity, and screen time were collected. RESULTS: Random effects growth models revealed that changes in child screen time moved in tandem with parent screen time from baseline to 14-week postintervention and from postintervention to 1-year follow-up. Greater parental monitoring predicted greater reduction in child calorie consumption at 1 year. CONCLUSIONS: Future studies should include innovative ways to explicitly involve parents in prevention efforts.

USDA Snack Policy Implementation: Best Practices From the Front Lines, United States, 2013-2014.

INTRODUCTION: The Smart Snacks in Schools interim final rule was promulgated by the US Department of Agriculture (USDA) as authorized by the Healthy, Hunger-Free Kids Act of 2010 (PL 111-296) and implementation commenced beginning July 1, 2014; however, in the years leading up to this deadline, national studies suggested that most schools were far from meeting the USDA standards. Evidence to guide successful implementation of the standards is needed. This study examined snack policy implementation in exemplary high schools to learn best practices for implementation. METHODS: Guided by a multiple case study approach, school professionals (n = 37) from 9 high schools across 8 states were recruited to be interviewed about perceptions of school snack implementation; schools were selected using criterion sampling on the basis of the HealthierUS Schools Challenge: Smarter Lunchrooms (HUSSC: SL) database. Interview transcripts and internal documents were organized and coded in ATLAS.Ti v7; 2 researchers coded and analyzed data using a constant comparative analysis method to identify best practice themes. RESULTS: Best practices for snack policy implementation included incorporating the HUSSC: SL award's comprehensive wellness approach; leveraging state laws or district policies to reinforce snack reform initiatives; creating strong internal and external partnerships; and crafting positive and strategic communications. CONCLUSION: Implementation of snack policies requires evidence of successful experiences from those on the front lines. As federal, state, and local technical assistance entities work to ensure implementation of the Smart Snacks standards, these best practices provide strategies to facilitate the process.
