Assessing food security through cooking and food literacy among students enrolled in a basic food science lab at Appalachian State University

A dual relationship between food insecurity and inadequate food literacy among college students may be attributed to limited food literacy, availability and ability to prepare healthful foods. Experiences that increase food literacy can improve diet quality and reduce food insecurity. Research was conducted through a food literacy-based curriculum developed using Social Cognitive Theory and Experiential Learning Theory. Food literacy outcomes and food security level were measured pre- and post-term through a Qualtrics-based survey. Analyses included Wilcoxon Signed Rank test and McNemar test. Analysis was completed on participants who completed both the pre and post surveys (n = 39). Over 30% of participants identified as food insecure. Results showed an increase in food literacy-based behaviors, self-efficacy and confidence (p<.05) in several measurements. Food security did not significantly improve; however, a positive trend toward food secure habits was observed. Food literacy-based self-efficacy and behaviors improved, which increases the potential for engagement and adaptation of related behaviors. Improvements observed may provide positive coping skills to reduce food insecurity. Incorporating a Basic Foods Lab into the General Education, Wellness Literacy curriculum can increase food literacy skills that may translate into reduced food insecurity.

School Nutrition Director Perceptions of Flexible Regulations for School Nutrition Programs in One Southeastern State

BACKGROUND

Schools are a promising site for influencing the dietary intake of children and adolescents. The US Department of Agriculture recently released flexibilities to requirements for whole-grains, sodium, and low-fat milk in schools who demonstrated difficulty meeting nutrition standards for school meal programs. The support of School Nutrition Directors (SNDs) is vital to the success of school food environment changes; however, few studies have explored SNDs perceptions to changes in nutrition standards.

METHODS

Experiences and perspectives toward nutrition standards of 10 SNDs, and their satisfaction with flexibilities for whole-grains, sodium, and low-fat milk were explored using a semi-structured interview. Responses were analyzed using an inductive approach with thematic analysis.

RESULTS

Three broad categories emerged challenges with the Healthy, Hunger-Free Kids Act, food preferences and acceptability, and support and representation. A greater need for internal and external support, assistance in equipment and staff, procurement of foods compliant with regulations and acceptable to students, and more input on federal decisions and policies were perceived as important.

CONCLUSIONS

Results provide critical insight into the implementation of nutrition standards. Future research and changes to school nutrition programs should consider these challenges as they strive to meet the needs of this important population.

Serotonin2A receptor binding potential in people with aggressive and violent behaviour

OBJECTIVE

Indexes of brain serotonin2A (5-HT2A) density have never been investigated in a sample of humans with violent aggressive behaviour unbiased by medication use or current axis I psychiatric disorders. The objective of this study was to investigate prefrontal cortex 5-HT2A binding potential (BPND), an index of 5-HT2A density, in an unbiased sample of people with violent aggressive behaviour.

METHODS

We used [18F] setoperone positron emission tomography to measure 5-HT2A BPND in the dorsolateral prefrontal cortex (primarily sampling Brodmann area 9) in 16 participants with violent aggressive behaviour and 16 healthy control participants.

RESULTS

In people with violent aggressive behaviours, the slope of 5-HT2A BPND decline in the dorsolateral prefrontal cortex is 44% less than in healthy control participants (analysis of variance group by age interaction, p = 0.004). Prefrontal cortex 5-HT2A BPND was significantly lower in participants with more severe impulsivity and aggression (multiple linear regression with age and Barratt Impulsivity Scale [BIS] as predictor variables and regional 5-HT2A BPND as dependent variable; effect of BIS, dorsolateral prefrontal cortex: F1,13 = 7.95, p = 0.014).

CONCLUSION

Lower prefrontal 5-HT2A BPND is related to violent aggression. Lower 5-HT2A BPND occurs at a younger age, when violent behaviour is more frequent, and is more prominent when impulsivity and aggression are more severe.
