RESUMO

OBJECTIVE: To determine nutrition practitioners' attitudes, behavioural control and normative beliefs to best inform the development and formulation of a nutrition-specific Dissemination and Implementation (D&I) science training. DESIGN: A cross-sectional survey aimed to assess Theory of Planned Behaviour (TPB) constructs and intention to use D&I science. A validated TPB questionnaire assessed constructs including perceived behavioural control, subjective, injunctive and descriptive normative beliefs, attitudes and intention to use D&I science. For analysis, Spearman's ρ, Kruskal-Wallis and Steel-Dwass tests were conducted for quantitative variables. SETTING: Online, 26-item Qualtrics survey. PARTICIPANTS: Cross-sectional sample of members (n 70) affiliated with the Society for Nutrition Education and Behaviour listserv. RESULTS: The major finding from this study was a significant positive correlation between perceived behavioural control score and intention (r = 0·315, P = 0·0119). CONCLUSIONS: D&I training interventions could formulate learning and teaching strategies to target perceived behavioural control (self-efficacy, knowledge and ability) to enhance intention. For example, application and experience-based learning techniques trainings could be strategies to increase knowledge and abilities.

RESUMO

PURPOSE: There is little investigation into the causes of food addiction. The aim of this study was to determine the impact of early life influences on the development of food addiction in college-attending young adults aged 18-29. METHODS: This study utilized a sequential explanatory mixed-methods research design. College-attending young adults were invited to complete an online survey measuring Adverse Childhood Experiences (ACEs), food addiction, depression, anxiety, stress, and demographic information. Correlations between food addiction and the other variables were analyzed and significant variables were placed into a nominal logistic regression model to predict the development of food addiction. Participants who met the criteria for food addiction were invited to participate in interviews to examine their childhood eating environment and when their symptoms emerged. Interviews were transcribed and thematically analyzed. Quantitative analysis was conducted using JMP Pro Version 16.0 and qualitative analysis was conducted using NVIVO Software Version 12.0. RESULTS: Survey respondents (n = 1645) had an overall 21.9% prevalence of food addiction. Significant correlations were observed between food addiction and ACEs, depression, anxiety, stress, and sex (p < .01 for all). Depression was the only significant predictor of the development of food addiction (OR = 3.33 95% CI 2.19, 5.05). The most common eating environment described by interview participants (n = 36) was an emphasis on diet culture, ideal body image, and restrictive environments. Symptoms frequently emerged after transitioning into college and having the ability to make their own food choices. CONCLUSION: These results show the impact of early life eating environments and young adulthood mental health on the development of food addiction. These findings contribute to the understanding of underlying causes of food addiction. LEVEL OF EVIDENCE: Level V, Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

RESUMO

Background: The COVID-19 pandemic can cause in increase in stress experienced by college students and consequently, potentially adversely affect their health behaviours. Aims: The aim of this study was to investigate how COVID-19 impacted college-attending young adults diet quality and physical activity. Methods: Students attending an Appalachian university in spring 2020 participated in this cross-sectional study. Participants were surveyed on their eating habits, diet quality, and physical activity before and since COVID-19. Frequencies of responses were analyzed and Bowker's test was used to determine differences in responses before and since COVID-19. Alpha was set at 0.05. Results: Almost one third (32.6%) of students reported eating somewhat more since COVID-19 and 67.9% of these students stated it was due to boredom. Students showed a significant increase in frequency of eating and in consumption of almost every food group. The number of students engaging in low physical activity increased from 27.8% to 51.9% and the number of students engaging in high physical activity decreased from 59.5% to 34.0% (p < .0001) and many switched to the use of at-home workouts. Conclusion: Results indicate the effects of campus closure on college student's lifestyles and the risk of developing health problems due to the COVID-19 pandemic, potentially inhibiting their academic progress and well-being.

RESUMO

Adult physical activity levels influence youth physical activity levels, but the nature of this relationship is still unknown. Most research focusing on this topic has been conducted with accelerometers, which are ideal since self-report physical activity measures can be biased. However, self-report measures for physical activity are useful to include in studies to gather information at low-cost. The purpose of this study was to further develop a self-report adult-youth dyad measure of physical activity. This study was conducted using secondary data analysis of the physical activity measures used in an intervention on behavioral nutrition (iCook 4-H). Participants were a sample of 214 adults (M = 39.0, SD = 8.0 years) and youth (M = 9.4, SD = 0.7 years) pairs. Accelerometer data was collected for a subset of youth (n = 122). There was dependency between the adult-youth physical activity data, and a dyadic confirmatory factor analysis model showed good fit to the data and achieved metric invariance, a measure to determine if the same construct was being measured in both youth and adults. Invariance was confirmed across matched versus unmatched sex pairs and some evidence of invariance with youth accelerometer data. Based on study findings, when using self-report measures of physical activity, researchers should measure both members of the adult-youth dyad to get more accurate measurements. Further validation of these findings is needed using an objective physical activity measure, like accelerometers, with all participants and more diverse samples.

RESUMO

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 < 0·0001) and reported more days with poor mental (P < 0·0001) and physical (P < 0·0001) health as well as days when mental and physical health prevented them from completing daily activities (P < 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.

RESUMO

OBJECTIVES: In order to determine methods to reduce vaping prevalence, motivations for use and co-occurring health behaviors and disorders need to be determined. This study investigated vaping characteristics and associated health behaviors in a young adult Appalachian college population. METHODS: Students attending an Appalachian university were invited to participate in an online survey measuring their use of e-cigarettes, motivations for use, mental health, and Adverse Childhood Experiences (ACEs). Analysis included prevalence of e-cigarette use and associations between e-cigarette use and Appalachian identity, mental health, and ACEs. RESULTS: Participants (N = 3398) stated that the most common motivator for using e-cigarettes was to decrease stress, followed by the good taste, friends' usage, and wanting to quit cigarettes. E-cigarette use was associated with alcohol use, anxiety, depression, stress, and Adverse Childhood Experiences (ACEs) and these variables were placed into a full logistic regression model, in which anxiety and stress were no longer significant, and alcohol use was the strongest association (OR 1.36 95% CI 1.35-1.42, p<.0001).Conclusions/importance: Findings demonstrate a need for efforts to reduce e-cigarette use to focus on the co-use of alcohol, co-occurring mental health disorders, and the social and enjoyment motivations for use.

RESUMO

BACKGROUND: There is a positive cross-sectional relationship between alcohol-related proactive dietary restriction to feel the effects of alcohol faster (APDR) and binge drinking, a health and safety issue impacting college students. Objective: To examine: 1) the longitudinal predictive ability of varying levels of APDR on binge drinking frequency; and 1a) the strength of the relationship between varying levels of APDR and binge drinking frequency during freshman year of college (n = 1,149). METHODS: Ordinal logistic regression was used to model the relationship between APDR and binge drinking frequency. RESULTS: Main findings suggest APDR of students who reported eating less than usual (low APDR) prior to drinking to feel the effects of alcohol faster was a significant predictor of binge drinking frequency (1.27 (95% CI, 0.06 to 0.42), Wald χ2 (1) = 8.46, p=.009) at baseline, but not at 7-month follow-up (1.02 (95% CI, -0.18 to 0.23), Wald χ2 (1) = .51, p=.83). APDR for students who reported skipping one or more meals (high APDR) to feel the effects of alcohol faster was not a significant predictor of binge drinking frequency at baseline nor at 7-month follow-up. CONCLUSION: Low APDR is a significant predictor of binge drinking frequency that is established early in the first semester of college with no significant change occurring in binge drinking frequency over the course of students' freshman year at 7-month follow-up. Campus health professionals are urged to emphasize the detrimental health effects of low APDR early in the first semester of college.

RESUMO

Refugee-specific nutrition and cooking curricula addressing dietary acculturation barriers to food security are limited. A cooking curriculum was culturally adapted for Burundian and Congolese refugees to address their unique dietary acculturation experiences. A four-phase curriculum adaptation process (information gathering [literature review, researcher informed, and formative interviews; n = 18], preliminary adaptation design [data incorporation and steering committee; n = 5], pilot testing [n = 10 youth/adult dyads], and refinement) was applied to the existing evidence-based iCook 4-H curriculum using a five-strategy (peripheral, evidential, linguistic, constituent-involving, and sociocultural) cultural adaptation framework. A multiphase, two-cycle coding analytic process was completed within NVivo 12, followed by direct content analysis. Seventeen adaptations were made to the iCook curriculum, derived from varying combinations of four data sources (literature review, researcher informed, priority population, and steering committee), applying all five cultural adaptation strategies. A majority of the curriculum adaptations were derived from two or more data sources (71%) and were categorized within multiple adaptation strategies (88%). This study provided a community-based cultural adaptation process that could be used with various populations to address unique barriers and facilitators to food security. This innovative model addresses cultural needs while simultaneously aiming to improve health habits of refugee communities.

RESUMO

Health professionals generally have positive attitudes towards the role of nutrition in medicine, but limited knowledge and low self-efficacy for incorporating it into routine care. To assess the effectiveness of a "learn first, practice second" intervention on the nutrition-related knowledge, attitudes, and self-efficacy of multidisciplinary health professionals, the present approach consisted of 16 weeks of online education and 2 weeks of cultural immersion in Tuscany, Italy. Data was captured via online surveys at Baseline, Post-education, Post-immersion, and Follow Up. Repeated measures ANOVA with irregular spacing was used, followed by Dunnett's or Cochran-Mantel-Haenszel testing. Results indicate significantly improved participant nutrition knowledge (nonzero correlation p = .0136, means score p = .0075) and self-efficacy (T0-T1 p < .0001, T0-T2 p < .0001, T0-T3 p = .0002), with differences in attitude trending towards significance (p = .0764). Findings from this study suggest that a combination of online education and hands on learning experiences can be beneficial for increasing health professionals' nutrition knowledge, confidence, and potentially attitude.

RESUMO

Pika Pamoja (Cook Together) is an eight-session cooking curriculum for Burundian and Congolese refugee families, culturally adapted from the evidence-based iCook 4-H curriculum to address dietary acculturation barriers to and facilitators of food security. The goal of this study was to determine the feasibility and acceptability of implementing Pika Pamoja. Researchers and a multilingual community aid implemented Pika Pamoja in a pre-post pilot intervention with randomized control (n = 5)/treatment (n = 5) dyads (youth/mother). Feasibility (recruitment/retention, implementation, fidelity testing, and assessment procedures) and acceptability (process and program evaluations) measures were collected. All 10 dyads (control and treatment) were retained throughout the study. All fidelity measures were 91% or above. The final youth assessment instrument included scales for cooking skills (α = 0.93), cooking self-efficacy (α = 0.90), openness to new foods (α = 0.81), and eating (α = 0.68), playing (α = 0.90), and setting healthful goals (α = 0.88) together as a family. The final adult instrument included scales for cooking, eating, and playing together (α = 0.68), kitchen proficiency (α = 0.89), and food security (α = 0.79). Participant feedback was uniformly positive. Based on these results, Pika Pamoja was feasible to implement and was accepted by the priority population. Larger scale studies to measure the effectiveness of Pika Pamoja to increase food security among refugee families are needed.

RESUMO

BACKGROUND: College students may be vulnerable to food insecurity due to limited financial resources, decreased buying power of federal aid, and rising costs of tuition, housing, and food. This study assessed the prevalence of food insecurity and its sociodemographic, health, academic, and food pantry correlates among first-year college students in the United States. METHODS: A cross-sectional study was conducted among first-year students (n = 855) across eight U.S. universities. Food security status was assessed using the U.S. Department of Agriculture Adult Food Security Survey Module. Cohen's Perceived Stress Scale, Pittsburgh Sleep Quality Index, and Eating Attitudes Test-26 were used to assess perceived stress, sleep quality, and disordered eating behaviors, respectively. Participants self-reported their grade point average (GPA) and completed questions related to meal plan enrollment and utilization of on-campus food pantries. RESULTS: Of participating students, 19% were food-insecure, and an additional 25.3% were at risk of food insecurity. Students who identified as a racial minority, lived off-campus, received a Pell grant, reported a parental education of high school or less, and did not participate in a meal plan were more likely to be food-insecure. Multivariate logistic regression models adjusted for sociodemographic characteristics and meal plan enrollment indicated that food-insecure students had significantly higher odds of poor sleep quality (OR = 2.32, 95% CI: 1.43-3.76), high stress (OR = 4.65, 95% CI: 2.66-8.11), disordered eating behaviors (OR = 2.49, 95% CI: 1.20-4.90), and a GPA < 3.0 (OR = 1.91, 95% CI: 1.19-3.07) compared to food-secure students. Finally, while half of the students (56.4%) with an on-campus pantry were aware of its existence, only 22.2% of food-insecure students endorsed utilizing the pantry for food acquisition. CONCLUSIONS: Food insecurity among first-year college students is highly prevalent and has implications for academic performance and health outcomes. Higher education institutions should screen for food insecurity and implement policy and programmatic initiatives to promote a healthier college experience. Campus food pantries may be useful as short-term relief; however, its limited use by students suggest the need for additional solutions with a rights-based approach to food insecurity.

RESUMO

PURPOSE OF REVIEW: Worldwide, diabetes has increased steadily and in recent years, drastically. The majority of diabetes cases are type 2 (T2DM), caused by modifiable risk factors such as diet. Vegetarian diets have been studied over the past few decades for their preventative and therapeutic effects on diabetes and may be more beneficial than medication for diabetes management. RECENT FINDINGS: A vegetarian diet characterized by whole plant foods is most beneficial for diabetes prevention and management. Vegetarian diets are inversely associated with risk of developing diabetes independent of the positive association of meat consumption with diabetes development. Vegetarian diets range from vegan (no animal products), lacto-ovo-vegetarian (no animal meat, but consumes milk and eggs), pesco-vegetarian (consumes fish), and semi-vegetarian (occasional meat consumption). There has been an observed difference in the extent of preventative and therapeutic effects of these different types of diets. The most important aspect of any of these types of diets is emphasizing whole grains, fruits and vegetables, legumes, and nuts and reducing saturated and trans fats.

RESUMO

It is important to understand adult outcomes in childhood obesity prevention programs as parents and caregivers have a significant influence on the eating and physical activity habits of youth. Grounded in the social cognitive theory, the iCook 4-H study was centered on a dyad model (9-10 year-olds and their primary meal preparers) to teach healthy cooking skills, shopping and meal habits, and being active as a family. The program took place in five states and dyads (n = 54) were recruited through flyers, e-mails, and in-person contact. The focus of this article is to provide findings from adult program participants. Demographics and self-reported food intake, procurement, preparation and safety practices, feeding relationships, mealtime routines, and height and weight were collected through surveys at baseline and program completion, which spanned 3 months. Descriptive statistics including two-related samples tests and paired samples t tests were used to assess pre- and post-program survey data responses at p < 0.05 significance level. Most had a bachelor's degree (31%) or some college (29%), about half were white, 66% were married, about 30% of households participated in assistance programs, and 82% were female. At program conclusion, participants significantly improved meal planning, prioritizing healthy meal choices, shopping with a grocery list, and reading Nutrition Facts Labels. There were also significant, positive differences noted in cooking skill confidence (p = 0.015), desire to cook more meals at home, and fewer fast food meals. Adult-youth feeding interactions also significantly improved. There were also significant increases in fruit juice (100%), vegetable soup, and whole grain consumption. Based on results, adults reported improvements in meal planning, cooking, and purchasing skills that were taught in classes.

RESUMO

BACKGROUND: The US National Physical Activity Plan (NPAP) was released in 2009 as a national strategic plan to increase physical activity (PA). The NPAP emphasized implementing state and local PA programs. Dissemination of information about NPAP has been limited, however. COMMUNITY CONTEXT: West Virginia is a predominantly rural state with high rates of chronic diseases associated with physical inactivity. In 2015 an evaluability assessment (EA) of the West Virginia Physical Activity Plan (WVPAP) was conducted, and community stakeholders were invited to participate in updating the plan. METHODS: A good EA seeks stakeholder input, assists in identifying program areas that need improvement, and ensures that a full evaluation will produce useful information. Data for this EA were collected via national stakeholder interviews, document reviews, discussions among workgroups consisting of state and local stakeholders, and surveys to determine how well the WVPAP had been implemented. OUTCOME: The EA highlighted the need for WVPAP leaders to 1) establish a specific entity to implement local PA plans, 2) create sector-specific logic models to simplify the WVPAP for local stakeholders, 3) evaluate the PA plan's implementation frequently from the outset, 4) use quick and efficient engagement techniques with stakeholders when working with them to select strategies, tactics, and measurable outcomes, and 5) understand the elements necessary to implement, manage, and evaluate a good PA plan. INTERPRETATION: An EA process is recommended for other leaders of PA plans. Our project highlights the stakeholders' desire to simplify the WVPAP so that it can be set up as a locally driven process that engages communities in implementation.

RESUMO

Metabolic syndrome (MetS) is the manifestation of a cluster of cardiovascular risk factors and is associated with a threefold increase in the risk of cardiovascular morbidity and mortality, which is suggested to be mediated, in part, by resting left ventricular (LV) systolic dysfunction. However, to what extent resting LV systolic function is impaired in MetS is controversial, and there are no data indicating whether LV systolic function is impaired during exercise. Accordingly, the objective of this study was to examine comprehensively the LV and arterial responses to exercise in individuals with MetS without diabetes and/or overt cardiovascular disease in comparison to a healthy control population. Cardiovascular function was characterized using Doppler echocardiography and gas exchange in individuals with MetS (n = 27) versus healthy control subjects (n = 20) at rest and during peak exercise. At rest, individuals with MetS displayed normal LV systolic function but reduced LV diastolic function compared with healthy control subjects. During peak exercise, individuals with MetS had impaired contractility, pump performance and vasodilator reserve capacity versus control subjects. A blunted contractile reserve response resulted in diminished arterial-ventricular coupling reserve and limited aerobic capacity in individuals with MetS versus control subjects. These findings are of clinical importance, because they provide insight into the pathophysiological changes in MetS that may predispose this population of individuals to an increased risk of cardiovascular morbidity and mortality.

RESUMO

OBJECTIVE: The aim of this study was to investigate how the COVID-19 pandemic impacted college student mental health and alcohol use and to determine how resilience could alleviate negative outcomes. PARTICIPANTS: Students attending an Appalachian university during spring 2020 were surveyed shortly after on-campus activities stopped. METHODS: Survey items included resilience, demographics, self-rated health, and depression symptoms, anxiety symptoms, and alcohol use before and since COVID-19. RESULTS: There was a significant increase in prevalence of severe depression, severe anxiety, and high stress, and a significant decrease in prevalence high risk for problem drinking before and since COVID-19. Four separate standard least squares regression models were conducted with each of the dependent variables. Self-rated health was the strongest predictor for changes in depression, anxiety, and stress in each of the models, displaying a negative relationship. CONCLUSIONS: Universities should prepare students using resilience training and provide employment and other resources to mitigate effects of stressful situations.

RESUMO

It is the position of the Society for Nutrition Education and Behavior that to improve the health of individuals, communities, and food systems, it is essential that nutrition educators meet each of 6 content competencies (basic food and nutrition knowledge, nutrition across the life cycle, food science, physical activity, food and nutrition policy, and agricultural production and food systems) and 4 process competencies (behavior and education theory; nutrition education program design, implementation and evaluation; written, oral, and social media communication; and nutrition education research methods). These competencies reflect the breadth of the nutrition education field and are grounded in peer-reviewed research. The rationale and evidence base for these competencies are presented. They are designed for educational institutions to plan curricula and programs; public, private, and nonprofit organizations for training; individuals for professional development; and policymakers and advocates to inform strong, comprehensive nutrition education policy.

RESUMO

Objective: This study aims to: (1) examine gender differences for weight conscious drinking among college students accounting for the broader phenomenon (e.g. including the Alcohol Effects dimension); and (2) longitudinally examine the effect of weight conscious drinking behaviors on body mass index (BMI). Participants: United States freshmen students from eight participating universities (N= 1,149). Methods: Structural equation modeling was used to model the effect of gender on weight conscious drinking dimensions at 7-month follow-up. Results: Findings suggest a significant effect of gender on Alcohol Effects (ß = -.15, SE = .05, p = .005) at 7-month follow-up among college freshmen. Weight conscious drinking dimensions predicted no significant change in BMI at 7-month follow-up among college freshmen. Conclusion: Findings contribute to weight conscious drinking theory and provide campus weight conscious drinking prevention initiatives with evidence to tailor their programming to address female tendencies to engage in compensatory strategies to enhance the psychoactive effects of alcohol.

RESUMO

BACKGROUND: College students are heavily influenced by their food environment and are an important population in which to study food addiction. This mixed-methods study aimed to examine diet quality and eating behaviors of college students with food addiction. METHODS: Students attending a large university in November 2021 were invited to complete an online survey that measured food addiction, eating styles, eating disorder symptoms, diet quality, and anticipated feelings after eating. Kruskal-Wallis H determined differences between those with and without food addiction in mean scores of quantitative variables. Participants who met the symptom threshold for the presence of food addiction were invited to participate in an interview that elicited more information. Quantitative data was analyzed using JMP Pro Version 16.0 and qualitative data was thematically analyzed using NVIVO Pro Software Version 12.0. RESULTS: Respondents (n = 1645) had a 21.9 % prevalence of food addiction. Individuals with mild food addiction had the highest scores in cognitive restraint. Those with severe food addiction had the highest scores in uncontrolled eating, emotional eating, and eating disorder symptoms. Individuals with food addiction showed significantly higher negative expectancies for healthy and junk food, lower intake of vegetables, higher intakes of added sugars and saturated fat. Interview participants had problems with sweets and carbohydrates most often and described eating until physically ill, eating in response to negative emotions, dissociation while eating, and strong negative feelings after eating. CONCLUSION: Findings contribute to the understanding of the behaviors, emotions, and perceptions surrounding food by this population, providing potential behaviors and cognitions to target for treatment.

RESUMO

OBJECTIVES: To quantify the number and type of students failing to secure basic needs. PARTICIPANTS: Students attending 22 postsecondary schools in the United States in Fall 2019. METHODS: The Adult Food Security Module and part of the #RealCollege Survey were used to measure food and housing insecurity, respectively. Logistic and linear regression models were used to assess the relationship between selected factors and basic needs insecurities. RESULTS: Participants (n = 22,153) were classified as 44.1% and 52.3% food insecure and housing insecure, respectively. Homeless students or those who experienced childhood food insecurity were at the greatest odds of college food insecurity. Year in school was the largest contributor to being housing insecure, with PhD or EdD students being 1,157% more likely to experience housing insecurity compared to freshmen. CONCLUSIONS: High prevalence of basic needs insecurities remain. Current campus initiatives may be insufficient, calling for a more holistic approach at the campus, state, and national levels.
