Telehealth-Based Health Coaching Increases m-Health Device Adherence and Rate of Weight Loss in Obese Participants.

Background: Healthy rate of weight loss (RWL) is defined as 1-2 lb of body weight loss per week. Objective: The objective of this study is to investigate changes in adherence to remote monitoring devices and RWL per week in response to a fully online, 12-week, medically monitored, weight management program incorporating weekly video-based health coaching (intervention group [INT]) versus self-guided (control group [CON]). Methods: Twenty-five obese participants (12 males, 13 females) were randomly assigned to either an INT (n = 13, 106.8 ± 25.46 kg, body mass index [BMI] = 35.19 ± 3.91 kg/m2) or CON group (n = 12, 99.8 ± 19.14 kg, BMI = 34.86 ± 4.43 kg/m2). Program related content was derived from inHealth Medical Services, Inc., Telehealth Enabled Approach to Multidisciplinary care (TEAM™) curriculum. All participants were given two wireless devices (Activity Pop and Body Scale; Withings®, Cambridge, MA) that connected them directly with the research team. The INT group connected via telehealth videoconferencing weekly for health coaching with the registered dietitian and monthly for medical monitoring with the physician, while the CON group did not. Both groups connected with the physician and registered dietitian at baseline to establish clinical goals and at the end to review progress. To analyze the data, independent samples t-tests and χ2 tests were performed via SPSS v24 with data displayed as average ± SD; significance set to p < 0.05. Results: The INT group had increased device adherence when compared with CON (92% ± 10% vs. 75% ± 15% scale [p < 0.05]) and (80% ± 14% vs. 49% ± 15% tracker [p < 0.05]). Furthermore, RWL per week was greater in the INT when compared with CON; -0.74 ± 1.8 kg versus 0.18 ± 1.8 kg per week, respectively (p < 0.05). Conclusions: Weekly health coaching via telehealth can be an effective tool to increase remote device adherence and may help to induce a healthy RWL.

Childhood nutrition in the Mississippi Delta: challenges and opportunities.

Childhood obesity in the USA has more than tripled in the last three decades, and the prevalence is higher in the Mississippi Delta. Insight into the social, cultural and environmental factors that influence inequity can inform efforts to mediate health disparities. Focus groups (n = 12) among parents/guardians of elementary school children (n = 44) and teachers (n = 59) in the Mississippi Delta were used to investigate barriers and facilitators of healthy eating. Transcriptions were analyzed for themes. A strong preference for junk food among children and the pervasiveness of junk foods in schools and communities were cited as barriers to healthy eating. Potential facilitators of healthy eating included desire to avoid chronic disease, effort to limit junk food consumption and school support. Despite support for efforts to improve nutrition in the Delta, participants voiced a sense of inevitability related to children's consumption of unhealthy foods. This study suggests that parents and teachers express concern related to eating habits of children, yet they experience barriers to healthy eating which contribute to a sense of disempowerment. Improving health in the Mississippi Delta requires comprehensive strategies that offer its citizens a sense of agency.

SNAP-Ed Programming for College Students Experiencing Food Insecurity: A Qualitative Process-Focused Evaluation.

BACKGROUND: Growing recognition of food insecurity experienced by college students has led to efforts on college campuses to provide students with food assistance benefits and related nutrition education. A Supplemental Nutrition Assistance Program-Education (SNAP-Ed) program was developed for college students as one of these efforts. OBJECTIVE: To explore program content, recruitment, and implementation through experiences of program implementers in a novel SNAP-Ed intervention among college students. DESIGN: This qualitative study used focus groups and a case study approach to elicit program implementers' experiences delivering SNAP-Ed to college students. PARTICIPANTS/SETTING: Students, staff, and faculty (n = 26) implementing SNAP-Ed with college students experiencing food insecurity across eight campuses in the California State University system participated in 8 focus groups in 2021-2022. MAIN OUTCOME MEASURES: A process evaluation framework was used to evaluate content fit and orientation; recruitment, retention, and reach; and structure and capacity for implementation. ANALYSES PERFORMED: Focus groups were recorded, transcribed, and coded via thematic analysis using NVivo (QSR International, Burlington, MA). RESULTS: Five themes were identified: (1) need for this work to extend college-based basic needs services; (2) importance of aligning programming with college student context/needs; (3) common factors important for attracting/engaging the audience; (4) program barriers; and (5) training/team sharing for extending ideas. CONCLUSIONS: Study findings suggest tailoring SNAP-Ed programming to the needs of college students experiencing food insecurity, such as integrating student-relevant cooking skills, recipes, and topics of interest. Additional intervention and research efforts may lead to a new model for serving college students with SNAP-Ed.

Food Insecurity Knowledge and Training Among College Students in Health Majors.

OBJECTIVE: To describe current food insecurity (FI)-related training among nutrition/dietetics, public health, and social work students. METHODS: A cross-sectional online survey was used among students (n = 306) enrolled in health-related programs at 12 US universities. Participants reported FI-related course-based and extracurricular experiences and rated confidence to address FI on a scale of 1-3. Open-ended questions investigated perceived definitions of FI and impactful course activities. Descriptive statistics and thematic analysis were used for data analysis. RESULTS: Participants' FI definitions were multifaceted. Most (80.6%) reported FI being covered in at least 1 course. The overall mean confidence to address FI was 2.2 ± 0.48. Participants suggested increasing application-based opportunities and skills training. CONCLUSIONS AND IMPLICATIONS: Most students have a basic understanding of FI and report high confidence to address it in the future. Impactful FI-related experiences and participants' suggestions guide developing an FI training resource to enhance student FI competency and sensitivity.

Food security as a basic need: College students need greater support from institutional administration.

Food insecurity among college students has become a growing concern, with reports documenting its prevalence for over a decade. As the demographics of university and college students change, with more first-generation, nontraditional, and minority students, the risk of food insecurity is heightened. This viewpoint contends that food security is an essential basic need among college students, and when left unmet, it significantly impacts their well-being, resulting in an increased risk of poor academic performance or departure from higher education before degree completion. To combat this issue, universities and colleges must develop and sustain food security initiatives and programs, with administrators playing a critical role. We highlight key areas in which institutional administration can take actionable steps to dedicate the necessary support and resources to proposed and ongoing programs, foster an equitable campus culture, and be advocates for policies at the state and federal level that promote students' food security.

Comparative analysis between a brief nutrition screening survey and validated food frequency questionnaire among physically active college students.

OBJECTIVE: To evaluate the agreement between a 61-item Nutrition Screening Survey (NSS) and 127-item validated Food Frequency Questionnaire (FFQ). PARTICIPANTS: Forty-seven college students (male, n = 29; female, n = 18), age 21.7 ± 0.4 years, BMI of 23.5 ± 0.4 kg/m2. METHODS: Participants completed the NSS, Block FFQ, and anthropometric measurements. Pearson's correlation, paired sample t test, and Bland-Altman plot evaluated agreement between the assessments. RESULTS: Moderate to strong associations between assessments (0.61-0.89, p < 0.001) were identified for meals/day, snacks/day, calories, carbohydrate, fiber, grains, non-starchy vegetables, potatoes, legumes, fruit, yogurt, cheese, and eggs. Mean daily meals/day, calories, fat, fiber, grains, fruit, milk, and eggs did not significantly differ between surveys. The Bland-Altman plot analyses indicated no proportional bias for calories, fat, fiber, grains, fruit, milk, and eggs. CONCLUSIONS: The NSS and Block FFQ display reasonable agreement, supporting use of the NSS for evaluating a range of dietary components among physically active college students.

Nutrition Education Curriculum Promotes Adolescent Runners' Self-Efficacy, Knowledge, and Intake of Nutrient-Rich Carbohydrate Foods.

BACKGROUND: Endurance runners exhibit an elevated prevalence of low bone mass and characteristics consistent with undernourishment. OBJECTIVE: This quasi-experimental, pretest-posttest design study evaluated the efficacy of a 4-week nutrition education curriculum to optimize nutrition knowledge, self-efficacy, and the intake of nutrient-rich carbohydrate foods. METHODS: Forty-eight adolescent endurance runners, age 15.7 ± 1.2 y, from two high schools in Southern California were recruited to complete four, weekly lessons addressing the quantity, quality, and timing of carbohydrate intake. Differences in pre- compared to post-intervention nutrition knowledge and self-efficacy to consume nutrient-rich carbohydrate foods were evaluated using paired samples t-tests. Qualitative coding of open-response questions explored changes in food intake behaviors reported by runners during the intervention. RESULTS: The percent of nutrition knowledge questions answered correctly increased after Lessons 1 and 2 (59.0% ± 20.0% pre- vs. 81.9% ± 22.8% post-Lesson 1; 44.7% ± 13.7% pre- vs. 74.5% ± 17.4% post-Lesson 2, P<.001) and the number of identified nutrient-rich carbohydrate foods (8.7 ± 2.7 vs. 12.4 ± 2.3, P < 0.001). Self-efficacy scores improved after all lessons (P<.001). After Lesson 2, 84% (n = 27/32) of runners increased the carbohydrate included in a snack or meal; after Lesson 4, 85% (n = 29/34) added a post-exercise snack. Frequent themes identified from questions addressing dietary changes included increasing quantity and quality of carbohydrates in snacks and meals and being more aware of food choices.Conclusions: Findings suggest that the curriculum enhanced nutrition knowledge, self-efficacy, and dietary behaviors related to intake of nutrient-dense carbohydrate foods in adolescent runners.

Support for inadvertent undereating in female adolescent athletes with clinical indicators of low energy availability.

OBJECTIVES: This study evaluated pathways to low energy availability in a sample of female adolescent athletes (n = 464). DESIGN: Cross-sectional. METHODS: Participants (age 13-18 y) underwent assessments for height, weight, eating attitudes and behaviors, and menstrual function. Bone mineral density and body composition were evaluated by dual-energy x-ray absorptiometry in a subset of participants (n = 209). Athletes were classified with clinical indicators of low energy availability if they met criteria for 1) primary or secondary amenorrhea or 2) clinical underweight status (body mass index-for-age < 5th percentile). Disordered eating was assessed using the Eating Disorder Examination Questionnaire. RESULTS: Thirty (6.5%) athletes exhibited clinical indicators of low energy availability, with higher estimates in leanness than non-leanness sports (10.9% vs. 2.1%, p < 0.005). Among athletes with clinical indicators of low energy availability, 80% (n = 24) did not meet criteria for disordered eating, eating disorder, or report the desire to lose weight. Athletes with (vs. without) clinical indicators of low energy availability exhibited lower lumbar spine (-1.30 ±â€¯1.38 vs. -0.07 ±â€¯1.21, p < 0.001) and total body (-0.30 ±â€¯0.98 vs. 0.53 ±â€¯0.97, p < 0.006) bone mineral density Z-scores. CONCLUSIONS: A majority of female adolescent athletes with clinical indicators of low energy availability did not exhibit characteristics consistent with intentional dietary restriction, supporting the significance of the inadvertent pathway to low energy availability and need for increased nutrition education in this population.

Positive Stimulation for Medically Sedated Patients: A Music Therapy Intervention to Treat Sedation-Related Delirium in Critical Care.

Sedation is an essential component of treatment for some patients admitted to the ICU, but it carries a risk of sedation-related delirium. Sedation-related delirium is associated with higher mortality and increased length of stay, but pharmacologic treatments for delirium can lead to oversedation or other adverse effects. Therefore, nonpharmacologic treatments are recommended in the literature; however, these recommendations are quite general and do not provide structured interventions. To establish a structured nonpharmacologic intervention that could improve indications of delirium after sedation, we combined evidence-based interventions including recordings of sensory-rich stories told by the patient's family and patient-specific music into our novel positive stimulation for medically sedated patients (PSMSP) protocol. The positive listening stimulation playlist organized by a board-certified music therapist (MT-BC) within the PSMSP protocol can be used in carefully monitored sessions with the MT-BC potentially to decrease agitation and stabilize arousal, as well as being played by nursing staff throughout the patient's recovery from sedation. Further controlled studies will be necessary, but the PSMSP protocol has the potential to reduce agitation and increase arousal during listening, as highlighted by the case of a patient recovering from sedation during treatment for COVID-19 pneumonia. It is important for the entire critical care team to be aware of nonpharmacologic treatments like PSMSP that are available for delirium mitigation so that, where applicable, these therapies can be incorporated into the patient's treatment regimen.

Adolescent Endurance Runners Exhibit Suboptimal Energy Availability and Intakes of Key Nutrients.

Backgroud: Despite the evidence of an elevated prevalence of low bone mass in adolescent endurance runners, reports on dietary intake in this population is limited.Objectives: This study aimed to evaluate energy availability (EA) and dietary intake among 72 (n = 60 female, n = 12 male) high school cross-country runners.Methods: The sample consisted of a combined dataset of two cohorts. In both cohorts, the Block Food Frequency Questionnaire (FFQ; 2005 & 2014 versions) assessed dietary intake. Fat free mass was assessed using dual-energy x-ray absorptiometry or bioelectrical impedance analysis.Results: Mean EA was less than recommended (45 kcal/kgFFM/day) among male (35.8 ± 14.4 kcal/kg FFM/day) and female endurance runners (29.6 ± 17.4 kcal/kgFFM/day), with 30.0% of males and 60.0% of females meeting criteria for low EA (<30 kcal/kgFFM/day). Calorie intake for male (2,614.2 ± 861.8 kcal/day) and female (1,879.5 ± 723.6 kcal/day) endurance runners fell below the estimated energy requirement for "active" boys (>3,100 kcal/day) and girls (>2,300 kcal/day). Female endurance runners' relative carbohydrate intake (4.9 ± 2.1 g/kg/day) also fell below recommended levels (6-10 g/kg/day). Male and female endurance runners exhibited below-recommended intakes of calcium, vitamin D, potassium, fruit, vegetables, grains, and dairy. Compared to male endurance runners, female endurance runners demonstrated lower relative intakes of energy (kcal/kg/day), protein (g/kg/day), fat (g/kg/day), fiber, vegetables, total protein, and oils.Conclusion: This study provides evidence of the nutritional risk of adolescent endurance runners and underscores the importance of nutritional support efforts in this population.

Cognitive dietary restraint score is associated with lower energy, carbohydrate, fat, and grain intake among female adolescent endurance runners.

This cross-sectional study investigated associations between cognitive dietary restraint (CDR), energy, macronutrient and food group intake, menstrual function, and bone density in female adolescent endurance runners. Participants were forty female adolescent endurance runners. The independent variable was CDR, as assessed by the Three Factor Eating Questionnaire (TFEQ). Runners with CDR subscale scores ≥11 were classified with elevated CDR. The main outcomes measured were dietary intake measured by 24-hour recall for 7 days, menstrual history, and bone mineral density (BMD). Twelve of 40 participants (30.0%) met criteria for elevated CDR. Compared to runners with normal CDR, runners with elevated CDR scores reported consuming lower energy (kcal/kg/day) (37.5 ± 8.6 vs. 44.0 ± 9.6, p = 0.052), lower carbohydrate (g/kg/day) (5.3 ± 1.3 vs. 6.3 ± 1.3, p = 0.042), more fiber (g/day) (24.9 ± 6.7 vs. 20.0 ± 5.3, p = 0.018), more servings of fruit (3.3 ± 1.4 vs. 1.9 ± 1.2, p = 0.003), more servings of vegetables (2.7 ± 1.4 vs. 1.7 ± 0.7, p = 0.004), and fewer servings of grain (7.6 ± 2.4 vs. 9.8 ± 2.4, p = 0.009) per day. Runners with elevated CDR exhibited significantly lower lumbar spine BMD Z-scores (adjusting for BMI) (-0.78 ± 0.19 vs. -0.22 ± 0.12, p = 0.016) than runners with normal CDR. Menstrual history did not significantly differ based on CDR status. Elevated CDR may increase risk of dietary patterns associated with consuming inadequate levels of energy, key nutrients, and developing low BMD in endurance runners.

Integrin-linked kinase functions as a downstream signal of platelet-derived growth factor to regulate actin polymerization and vascular smooth muscle cell migration.

BACKGROUND: Vascular smooth muscle cell migration and accumulation in response to growth factors extensively contribute to the development of intimal thickening within the vessel wall. Cumulative evidence has shown that actin cytoskeleton polymerization and rearrangement are critical steps during cellular spreading and migration. Integrin-linked kinase, an intracellular serine/threonine kinase, is a cytoplasmic interactor of integrin beta-1 and beta-3 receptors regulating cell-cell and/or cell-extracellular matrix interaction, cell contraction, extracellular matrix modification, and cell spreading and migration in response to various stimuli. However, the regulatory role of ILK during vascular smooth muscle cell migration and the importance of integrin signaling in occlusive vascular diseases are not yet fully elucidated. RESULTS: In the present study, we report that integrin-linked kinase controls mouse aortic smooth muscle cell migration in response to platelet-derived growth factor. We have also identified p38 mitogen activated protein kinase as a downstream signaling pathway of the integrin-linked kinase that regulates platelet-derived growth factor-induced actin polymerization and smooth muscle cell migration. CONCLUSION: This study will provide new insights into the potential therapeutic value of modulating integrin signaling in an attempt to block or delay smooth muscle cell migration and the progression of vascular diseases.

Significant Relationships Exist between Perceived and Objective Diet Quality in Young Adults.

BACKGROUND: There is a disproportionate burden of low diet quality among young adults compared with other adult subpopulations that is not understood. Perceived and objective diet qualities are studied to understand possible barriers to change. OBJECTIVE: To explore the association between perceived diet quality and objective diet quality in young adults in the United States. DESIGN: This cross-sectional study used data from the 2013-2014 National Health and Nutrition Examination Survey to calculate total Healthy Eating Index-2010 (HEI-2010) score and component scores and study their relationships with perceived diet quality scores. PARTICIPANTS/SETTING: The sample consisted of 1,261 young adults, aged 18 to 30, with 24-hour recall data. MAIN OUTCOME MEASURES: Perceived and objective diet quality were evaluated. STATISTICAL ANALYSES PERFORMED: Multiple regression analysis was used to test the ability to predict total HEI-2010 scores from perceived diet quality scores. Ordered logit was used to test whether HEI-2010 component scores predicted the odds of having higher perceived diet quality. RESULTS: Excellent (b=8.442, P<0.001), very good (b=9.733, P<0.001), and good (b=5.527, P<0.001) perceived diet quality were significant predictors of total HEI-2010 score, compared with the referent category of poor perceived diet quality. The full regression model predicted 17.0% of the variance in total HEI-2010 score. Whole fruit (odds ratio [OR]=1.098, P=.017), whole grains (OR=1.046, P=.023), and empty calories (OR=1.054, P<0.001) were each significantly associated with the odds of having a higher rating of perceived diet quality (fair, good, very good, excellent) instead of a poor rating of diet quality; the difference in odds was low across categories. CONCLUSIONS: There are significant relationships between perceived and objective diet quality, but other variables play a substantial role in explaining these two types of diet quality.

Development of a Family-Based Nutrition Program Rooted in Food Parenting Literature.

Family-based nutrition programs have been used to support healthy eating; however, few programs emphasize parental roles in regard to food. The purpose of this study was to develop and test a family-based curriculum with a parenting focus aimed at influencing child obesity risk. Qualitative data in the pilot implementation (cohort 1, n = 6 families with elementary-aged children) suggested parent value for: positive messages, hands-on learning, and group sharing. However, Family Nutrition and Physical Activity (FNPA) scores for cohorts 2-6 (n = 18 families) did not change significantly from pre- to post-program. Future implementations will consider more robust ways of assessing change and recruiting participants at various stages of change.

Qualitative Evaluation of Drivers of Eating Decisions among SNAP Participants in Mississippi.

OBJECTIVE: To explore food-related decision patterns among Supplemental Nutrition Assistance Program (SNAP) recipients in Mississippi. DESIGN: A qualitative design was used to conduct focus groups (n = 18) based on the Health Belief Model with low-income female caregivers of children aged under 13 years. SETTING: Mississippi. PARTICIPANTS: Cluster sampling was used to recruit participants (n = 126) from the 4 regional divisions of Mississippi State University Extension. PHENOMENON OF INTEREST: Drivers of eating decisions among SNAP participants. ANALYSIS: Focus groups were recorded, transcribed, and coded by 2 independent coders using thematic analysis. RESULTS: Drivers of food selection often overlapped with barriers to healthy eating. Participants used many strategies to manage costs and viewed healthy foods as out of reach and quick to perish. Cost, taste preferences, habits, and family factors were primary drivers of food selection and preparation; each of these presented barriers to healthier eating. Health was most often shared as a driver of food selection once disease was established. Participants reported a variety of strategies used in striving for healthier eating. CONCLUSIONS AND IMPLICATIONS: Focusing on ways to manage the costs of healthy foods, honor taste preferences, and work within habits/families may enhance efforts to support healthy eating among SNAP participants.

Prioritized Dietary Supplement Information Needs of 307 NCAA Division I Student Athletes.

OBJECTIVE: To evaluate dietary supplement information needs among collegiate athletes. METHODS: Three hundred seven (n = 154 male; n = 153 female) student athletes participating in a National Collegiate Athletic Association Division I team completed a dietary supplement survey. Qualitative coding addressed open-ended responses, and chi-square test of independence explored differences among athlete subgroups. RESULTS: Five themes representing athletes' information needs included quality/composition (53.5%; n = 77), general information (31.9%; n = 46), nutrition information (30.6%; n = 44), performance (18.8%; n = 27), and body composition (13.2%; n = 19). Athletes with "no" or "minimal" (n = 63), vs "moderate" or "strong" (n = 195), perceived knowledge of supplement safety were more likely to list a question about supplement quality or composition (34.9% [n = 22/63] vs 21.5% [n= 42/195]; P = .03; chi-square = 4.6). CONCLUSIONS AND IMPLICATIONS: Further research is needed to corroborate findings to inform educational efforts and promote safe and effective use of dietary supplements by student athletes.

The efficacy of a telemedicine-based weight loss program with video conference health coaching support.

INTRODUCTION: Clinically significant weight loss is defined as a ≥5% of initial body weight loss within a 6-month period. The purpose of this study was to assess body weight change from a 12-week telehealth-based weight loss program that integrated health coaching via video conferencing. METHODS: A total of 25 obese participants (12 males, 13 females) were recruited for this fully online 12-week weight loss program. Participants were randomly assigned to either an intervention group or control group ( n = 13 intervention, body mass index (BMI) = 34.7 ± 4.5 kg/m2; n = 12 control, BMI = 34.4 ± 4.43 kg/m2). All participants were given access to a secure platform for data tracking and video conferencing with the research team. The intervention group met with the medical doctor once per month and with a registered dietitian, weekly. Control participants met with the research team at baseline and at 12 weeks. Independent samples t-tests and Chi-square tests were used via SPSS version 24 with significance set to p < 0.05. RESULTS: There was a significant difference between the intervention and control groups for body weight loss (7.3 ± 5.2 versus 1.2 ± 3.9 kg, respectively, p < 0.05) as well as for percent body weight loss (7.16 ± 4.4 versus 1.5 ± 4.1%, respectively, p < 0.05). Clinically significant weight loss was achieved in 9 out of 13 (69.2%) in the intervention group versus 1 out of 12 (8%) in the control group. DISCUSSION: Mobile phone-based health coaching may promote weight loss. Weekly video conferencing with education may be an applicable tool for inducing significant body weight loss in obese individuals.

Parents Report Competing Priorities Influence Snack Choice in Youth Sports.

OBJECTIVE: To describe parental perceptions of team snacks, factors that motivate snack choice, and perceptions of healthy snacking guidelines in youth sports. METHODS: Six in-depth group interviews were conducted among parents (n = 22) of children aged 4-12 years in 2 Los Angeles County Baseball Little Leagues. Interviews were audio-recorded, transcribed, and analyzed using thematic analysis. RESULTS: Parents perceived fruit as the ideal snack; this ideal was balanced with competing priorities, including children's preferences, cost, time, and social norms regarding snacks as rewards and team bonding. Although parents were supportive of promoting healthy snacks, they believed that snacking guidelines should not be mandated. CONCLUSIONS AND IMPLICATIONS: Developing messages that align with parents' motivations when choosing snacks could promote healthier snacking in youth sports. Future studies are warranted to explore drivers of snacking with a broader sample and to examine how to promote healthy snacks effectively.

The GLP-1 response to glucose does not mediate beta and alpha cell dysfunction in Hispanics with abnormal glucose metabolism.

AIMS: Glucagon-like peptide-1 (GLP-1) contributes to insulin secretion after meals. Though Hispanics have increased risk for type 2 diabetes mellitus, it is unknown if impaired GLP-1 secretion contributes to this risk. We therefore studied plasma GLP-1 secretion and action in Hispanic adults. METHODS: Hispanic (H; n = 31) and non-Hispanic (nH; n = 15) participants underwent an oral glucose tolerance test (OGTT). All participants were categorized by glucose tolerance into four groups: normal glucose tolerant non-Hispanic (NGT-nH; n = 15), normal glucose tolerant Hispanic (NGT-H; n = 12), impaired glucose tolerant Hispanic (IGT-H; n = 11), or newly diagnosed type 2 diabetes mellitus, Hispanic (T2D-H; n = 8). RESULTS: Glucose-induced increments in plasma GLP-1 (Δ-GLP-1) were not different in NGT-H and NGT-nH (p = .38), nor amongst Hispanic subgroups with varying degrees of glucose homeostasis (p = .6). In contrast, the insulinogenic index in T2D-H group was lower than the other groups (p = .016). Subjects with abnormal glucose homeostasis (AGH), i.e., T2D-H plus IGT-H, had a diminished glucagon suppression index compared to patients with normal glucose homeostasis (NGT-H plus NGT-nH) (p = .035). CONCLUSIONS: GLP-1 responses to glucose were similar in Hispanic and Non-Hispanic NGT. Despite similar glucose-induced Δ-GLP-1, insulin and glucagon responses were abnormal in T2D-H and AGH, respectively. Thus, impaired GLP-1 secretion is unlikely to play a role in islet dysfunction in T2D. Although GLP-1 therapeutics enhance insulin secretion and glucagon suppression, it is likely due to pharmacological amplification of the GLP-1 pathways rather than treatment of hormonal deficiency.

Academic-Related Factors and Emotional Eating in Adolescents.

BACKGROUND: Existing literature indicates a relationship between stress and emotional eating in adults, yet limited research has examined the impact of school-related stress on emotional eating in adolescents. This study investigated the influence of academic factors on emotional eating among minority adolescents. METHODS: A survey was implemented among a sample of minority adolescents (N = 666) to investigate the relationship between emotional eating and 3 academic factors: academic self-esteem, grade point average (GPA), and academic worries. Forced-entry multiple linear regressions were used to test for relationships. RESULTS: Findings indicate that GPA, academic self-esteem, and academic worries were related to emotional eating scores in adolescents. There were no significant differences in academic factors between emotional eaters and nonemotional eaters. CONCLUSIONS: Additional research is needed to further elucidate the complex interaction between emotional eating behavior and academics.
