    Objective: This research project consisted of three studies designed to investigate intermediate school teachers’ classroom food-related practices and perceptions of the school nutrition environment Setting: The setting for this project was a rural county in the southern region of East Tennessee Design: This project used a mixed-methods approach to investigate teachers’ food-related practices and perceptions of the school nutrition environment, including grounded theory methodology, secondary data analysis, and a cross-sectional survey. Analyses: For the first study, the transcribed data were coded using open, axial, and selective coding and constant comparison of data. For the second study, descriptive and inferential statistics were used to compare teachers’ themes to student BMI and 24-hour recall data. For the final study, a factor analysis and regression analysis was used to determine what factors were predictive of teacher food-related classroom practices. Results: Rich details were obtained and a logic model was developed from the in-depth interviews in the first study. The second study yielded numerous significant results, including those which demonstrated that lunches students brought from home had significantly greater mean ranks of percent calories from carbohydrate and grams of total sugar and significantly less mean ranks of percent calories from protein and grams of fiber than lunches purchased at school. The factor analysis and descriptive statistics from the final study showed that many teachers used candy, pizza, and soft drinks as rewards, while fewer used more healthy food alternatives. Additionally, the regression analysis showed that years teaching at current school was predictive of less frequently reported use of teacher food-related practices that supported healthful eating among students, while a less supportive attitude regarding the school environment was predictive of more frequent reported use of less healthful classroom food-related practices Conclusions: Teachers were able to identify key areas in the school environment that may have influenced students’ diet quality and weight status. However, there were mixed results when comparing teacher-identified themes about the school nutrition environment with student BMI and 24-hour recall data. In addition, many teachers used classroom food-related practices that were not supportive of healthful eating behaviors among students

    This paper presents a formative evaluation of an afterschool program that combined positive youth development and school garden curricula. Novel approaches were used to teach elementary school children about gardening and nutrition, and to engage them in advocacy for healthy community physical activity and nutrition environments. The youth development curriculum included sessions on team building, community pride, healthy eating, physical activity, and advocacy. Photovoice methods were used to allow participants to assess their community and communicate findings with community leaders. The school garden curriculum included nutrition and gardening lessons. Formative evaluation was conducted for each session. Themes of the evaluation were: successful methods for engaging youth, issues in the social environment, and implications for program management. Evaluation results are discussed in relationship to relevant youth development literature to provide recommendations that will strengthen future programs

    More than Fast Food: Development of a Story Map to Compare Adolescent Perceptions and Observations of Their Food Environments and Related Food Behaviors

    The purpose of this convergent, multiphase, mixed methods study was to better understand the perceptions of adolescents’ food environments and related food behaviors using grounded visualization and story mapping. Adolescents from one high school (13–16 years) in the southeastern United States were evaluated via data from health behavior surveys (n = 75), school environment maps, focus groups (n = 5 groups), and Photovoice (n = 6) from October 2016 to April 2017. Data from each phase were integrated using grounded visualization and new themes were identified (n = 7). A story map using ArcGIS Online was developed from data integration, depicting the newly identified themes. Participants failed to meet national recommendations for fruit and vegetable intake (2.71 cups). Focus group and Photovoice findings indicated the need for convenience food items in all environments. The story map is an online, interactive dissemination of information, with five maps, embedded quotes from focus groups, narrative passages with data interpretation, pictures to highlight themes, and a comparison of the participants’ food environments. Story mapping and qualitative geographic information systems (GIS) approaches may be useful when depicting adolescent food environments and related food behaviors. Further research is needed when evaluating story maps and how individuals can be trained to create their own maps

    Background A number of studies have measured college student food insecurity prevalence higher than the national average; however, no multicampus regional study among students at 4-y institutions has been undertaken in the Appalachian and Southeast regions of the United States. Objectives The aims of this study were to determine the prevalence of food insecurity among college students in the Appalachian and Southeastern regions of the United States, and to determine the association between food-insecurity status and money expenditures, coping strategies, and academic performance among a regional sample of college students. Methods This regional, cross-sectional, online survey study included 13,642 college students at 10 public universities. Food-insecurity status was measured through the use of the USDA Adult Food Security Survey. The outcomes were associations between food insecurity and behaviors determined with the use of the money expenditure scale (MES), the coping strategy scale (CSS), and the academic progress scale (APS). A forward-selection logistic regression model was used with all variables significant from individual Pearson chi-square and Wilcoxon analyses. The significance criterion α for all tests was 0.05. Results The prevalence of food insecurity at the universities ranged from 22.4% to 51.8% with an average prevalence of 30.5% for the full sample. From the forward-selection logistic regression model, MES (OR: 1.47; 95% CI: 1.40, 1.55), CSS (OR: 1.19; 95% CI: 1.18, 1.21), and APS (OR: 0.95; 95% CI: 0.91, 0.99) scores remained significant predictors of food insecurity. Grade point average, academic year, health, race/ethnicity, financial aid, cooking frequency, and health insurance also remained significant predictors of food security status. Conclusions Food insecurity prevalence was higher than the national average. Food-insecure college students were more likely to display high money expenditures and exhibit coping behaviors, and to have poor academic performance

    Objectives To define and validate types of pain in critically ill neonates and infants by researchers and clinicians working in the neonatal intensive care unit (NICU) and high dependency unit (HDU). Design A qualitative descriptive mixed-methods design. Procedure/s Each stage of the study was built on and confirmed the previous stages. Stage 1 was an expert panel to develop definitions; stage 2 was a different expert panel made up of neonatal clinicians to propose clinical characteristics associated with the definitions from stage 1; stage 3 was a focus group of neonatal clinicians to provide clinical case scenarios associated with each definition and clinical characteristics; and stage 4 was a survey administered to neonatal clinicians internationally to test the validity of the definitions using the clinical case scenarios. Results In stage 1, the panel (n=10) developed consensus definitions for acute episodic pain and chronic pain in neonates and infants. In stage 2, a panel (n=8) established clinical characteristics that may be associated with each definition. In stage 3, a focus group (n=11) created clinical case scenarios of neonates and infants with acute episodic pain, chronic pain and no pain using the definitions and clinical characteristics. In stage 4, the survey (n=182) revealed that the definitions allowed an excellent level of discrimination between case scenarios that described neonates and infants with acute episodic pain and chronic pain (area under the receiver operating characteristic=0.87 and 0.89, respectively). Conclusions This four-stage study enabled the development of consensus-based and clinically valid definitions of acute episodic pain and chronic pain. There is a need to define and validate other pain types to inform a taxonomy of pain experienced by neonates and infants in the NICU and HDU

    Objective: To assess the relationship between food insecurity, sleep quality, and days with mental and physical health issues among college students. Design: An online survey was administered. Food insecurity was assessed using the ten-item Adult Food Security Survey Module. Sleep was measured using the nineteen-item Pittsburgh Sleep Quality Index (PSQI). Mental health and physical health were measured using three items from the Healthy Days Core Module. Multivariate logistic regression was conducted to assess the relationship between food insecurity, sleep quality, and days with poor mental and physical health. Setting: Twenty-two higher education institutions. Participants: College students (n 17 686) enrolled at one of twenty-two participating universities. Results: Compared with food-secure students, those classified as food insecure (43·4 %) had higher PSQI scores indicating poorer sleep quality (P \u3c 0·0001) and reported more days with poor mental (P \u3c 0·0001) and physical (P \u3c 0·0001) health as well as days when mental and physical health prevented them from completing daily activities (P \u3c 0·0001). Food-insecure students had higher adjusted odds of having poor sleep quality (adjusted OR (AOR): 1·13; 95 % CI 1·12, 1·14), days with poor physical health (AOR: 1·01; 95 % CI 1·01, 1·02), days with poor mental health (AOR: 1·03; 95 % CI 1·02, 1·03) and days when poor mental or physical health prevented them from completing daily activities (AOR: 1·03; 95 % CI 1·02, 1·04). Conclusions: College students report high food insecurity which is associated with poor mental and physical health, and sleep quality. Multi-level policy changes and campus wellness programmes are needed to prevent food insecurity and improve student health-related outcomes

    A Pan-Canadian Validation Study for the Detection of EGFR T790M Mutation Using Circulating Tumor DNA From Peripheral Blood

    Introduction: Genotyping circulating tumor DNA (ctDNA) is a promising noninvasive clinical tool to identify the EGFR T790M resistance mutation in patients with advanced NSCLC with resistance to EGFR inhibitors. To facilitate standardization and clinical adoption of ctDNA testing across Canada, we developed a 2-phase multicenter study to standardize T790M mutation detection using plasma ctDNA testing. Methods: In phase 1, commercial reference standards were distributed to participating clinical laboratories, to use their existing platforms for mutation detection. Baseline performance characteristics were established using known and blinded engineered plasma samples spiked with predetermined concentrations of T790M, L858R, and exon 19 deletion variants. In phase II, peripheral blood collected from local patients with known EGFR activating mutations and progressing on treatment were assayed for the presence of EGFR variants and concordance with a clinically validated test at the reference laboratory. Results: All laboratories in phase 1 detected the variants at 0.5 % and 5.0 % allele frequencies, with no false positives. In phase 2, the concordance with the reference laboratory for detection of both the primary and resistance mutation was high, with next-generation sequencing and droplet digital polymerase chain reaction exhibiting the best overall concordance. Data also suggested that the ability to detect mutations at clinically relevant limits of detection is generally not platform-specific, but rather impacted by laboratory-specific practices. Conclusions: Discrepancies among sending laboratories using the same assay suggest that laboratory-specific practices may impact performance. In addition, a negative or inconclusive ctDNA test should be followed by tumor testing when possible

    Using Blogs to Identify Misconceptions in a Large Undergraduate Nutrition Course

    No full text
    We describe two iterations of the design, development, implementation and evaluation of small online activity and reflection blogging groups into a large undergraduate lecture course in nutrition. Our goal was to promote student learning and conceptual change through reflection and interaction in blog conversations. We found the blog conversations to be highly useful to the instructors as a source of data on student understandings and misconceptions of course topics. These misconceptions could then be addressed with further instruction. We found that, even with initial training, graduate teaching assistants needed significant guidance in facilitation strategies and that finding the ideal balance between structure and autonomy is a design challenge
