ObjectivesThis study was conducted to examine sexual dimorphic effects of highly palatable food access during adolescence and youth on psychoemotional behaviors of rats and its underlying neural mechanism.MethodsMale and female Sprague Dawley pups had free access to chocolate cookie rich in fat (highly palatable food) from postnatal day 28 in addition to ad libitum chow, and the control groups received chow only. The food conditions were continued though out the entire experimental period, and the neurochemical and behavioral measurements were performed during young adulthood. Corticosterone levels during 2 h of restraint stress were analyzed with radioimmunoassay, and ΔFosB and brain-derived neurotrophic factor (BDNF) expression in the nucleus accumbens (NAc) with western blot analysis.ResultsCookie access did not affect body weight gain and total caloric intake in both sexes; however, it increased retroperitoneal fat depot only in males. The time spent in open arms during elevated plus maze test was decreased and immobility during forced swim test was increased in cookie-fed males, but not in cookie-fed females. Main effect of food condition on the stress-induced corticosterone increase was observed in males, but not in females, and cookie access increased BDNF expression in the NAc only in males.ConclusionsIncreased BDNF expression in the NAc and fat depot, in addition to the HPA axis dysfunction, may play roles in the pathophysiology of depression- and/or anxiety-like behaviors induced by cookie access.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Purpose: Examine if Historically Black Colleges and Universities (HBCUs) are more likely to be located in low food access area (LFA) census tracts compared to public non-HBCUs. Design: ArcGIS Pro was utilized to capture food environments and census tract sociodemographic data. Setting: The sample included 98 HBCUs and 777 public non-HBCUs within the United States. 28.9% of study census tracts were classified as LFA tracts. Measures: University data were gathered from the National Center for Education Statistics. Census tract-level LFA classification was informed by the United States Department of Agriculture’s Food Access Research Atlas. Covariates included population density and neighborhood socioeconomic status of census tracts containing subject universities. Analysis: Multilevel logistic regression was employed to examine the relationship between university type and LFA classification. Results: A higher percentage of HBCUs (46.9%) than public non-HBCUs (26.6%) were located in LFAs. After adjusting for population density and neighborhood socioeconomic status, university type was significantly associated with food access classification (B=0.71;p=.0036). The odds of an HBCU being located in LFA tracts were 104% greater than for a public non-HBCU (OR=2.04;95% CI=1.26,3.29). Conclusion: Findings underscore the need for policy interventions tailored to HBCU students to promote food security, environmental justice, and public health.

Abstract Background The North Carolina Healthy Food Small Retailer Program (NC HFSRP) was established through a policy passed by the state legislature to provide funding for small food retailers located in food deserts with the goal of increasing access to and sales of healthy foods and beverages among local residents. The purpose of this study was to qualitatively examine perceptions of the NC HFSRP among store customers. Methods Qualitative interviews were conducted with 29 customers from five NC HFSRP stores in food deserts across eastern NC. Interview questions were related to shoppers’ food and beverage purchases at NC HFSRP stores, whether they had noticed any in-store efforts to promote healthier foods and beverages, their suggestions for promoting healthier foods and beverages, their familiarity with and support of the NC HFSRP, and how their shopping and consumption habits had changed since implementation of the NC HFSRP. A codebook was developed based on deductive (from the interview guide questions) and inductive (emerged from the data) codes and operational definitions. Verbatim transcripts were double-coded and a thematic analysis was conducted based on code frequency, and depth of participant responses for each code. Results Although very few participants were aware of the NC HFSRP legislation, they recognized changes within the store. Customers noted that the provision of healthier foods and beverages in the store had encouraged them to make healthier purchase and consumption choices. When a description of the NC HFSRP was provided to them, all participants were supportive of the state-funded program. Participants discussed program benefits including improving food access in low-income and/or rural areas and making healthy choices easier for youth and for those most at risk of diet-related chronic diseases. Conclusions Findings can inform future healthy corner store initiatives in terms of framing a rationale for funding or policies by focusing on increased food access among vulnerable populations.
