RESUMO
BACKGROUND: Coeliac disease (CeD), a common autoimmune condition, requires strict adherence to a gluten-free diet (GFD). Adherence to the GFD has been associated with quality of life (QOL). However, there may be other diet-related concerns, such as overall diet patterns, including diet quality or ultra-processed food (UPF) consumption, possibly associated with QOL among people with CeD following a GFD that have not been examined. METHODS: Diet quality was determined based on 24-h diet recalls of a cross-sectional prospectively recruited sample of 80 participants (50 adults and 30 teens) with biopsy-confirmed CeD ('Study Sample') using the Healthy Eating Index and Alternate Mediterranean Diet score. The amount of UPF consumed was assessed using Nova, a food processing classification system. QOL was measured using Celiac Disease-Specific Quality of Life (CDQOL) and Celiac Disease Pediatric-Specific Quality of Life (CDPQOL). The Study Sample's diet patterns were compared with National Health and Nutrition Examination Survey (NHANES) groups (25 adults reporting prior CeD and GFD; 51 adults with new CeD and no GFD; 15,777 adults and 2296 teens without CeD). The relationship of the Study Sample's diet patterns with CDQOL/CDPQOL was assessed using analysis of covariance. RESULTS: The Study Sample's diet patterns were suboptimal but generally favourable compared with all NHANES groups. Compared to Study Adults with the highest tertile of UPF, those with the lowest tertile had significantly higher CDQOL (mean: 67.6 vs. 78.3, p < 0.001). Compared to Study Teens with the lowest tertile of AMED, those with the highest tertile had significantly higher CDPQOL (mean: 67.0 vs. 79.9, p < 0.01). CONCLUSIONS: Maintaining high diet quality and minimising UPF may be important for CeD-specific QOL among individuals with CeD maintaining a GFD.

OBJECTIVES: There is limited guidance on how to effectively educate cancer survivors to adopt and maintain specific diet and physical activity recommendations, especially among underserved and under-resourced populations. Here, the objective is to present the development of a behavioral and theoretically-based multi-modal diet and physical activity intervention program for Hispanic/Latina breast cancer survivors, Mi Vida Saludable (My Healthy Life). METHODS: The development process was based on the 6 steps of the Nutrition Education DESIGN Procedure: (1). Decide behaviors; (2). Explore determinants; (3). Select theory-based model; (4). Indicate objectives; (5). Generate plans; and (6). Nail down evaluation. The theoretical framework for the intervention is Social Cognitive Theory. RESULTS: The resulting behavioral intervention consists of 2 components. The first component is in-person group education consisting of 4 lessons over 1 month. Each 4-hour group lesson includes a hands-on cooking component, a physical activity component, and facilitator-led nutrition education and discussion, with 2 field trips to a local grocery store and farmers' market. The second component is an e-Health program that includes weekly text messages, biweekly emailed newsletters, and ongoing website access. CONCLUSION: The systematic DESIGN Procedure provided practical guidance for developing a behaviorally-focused, theory-based, and culturally sensitive program that addresses both dietary and physical activity behaviors for delivery both in-person education and through eHealth. The Procedure may be useful for developing other behaviorally focused and theory-based interventions.

Current treatment for celiac disease (CD) requires a life-long gluten-free diet (GFD).1 Among the top challenges are eating outside the home2 and over-reliance on processed foods, which are often high-fat, low-fiber, and high-sugar.3 Home cooking is a GFD management strategy that addresses both. Research not specific to CD suggests a variety of positive outcomes related to home cooking: healthier dietary pattern, positive self-management behaviors (eg, improved glycosylated hemoglobin and cholesterol levels), increased willingness to integrate complex dietary changes, and improved quality of life (QOL).4-6 In this study we assessed the feasibility and acceptability of a cooking-based nutrition education intervention to promote GFD adherence and QOL among adults with CD.

Presently in the U.S., few children meet the recommendation for daily consumption of fruits and vegetables (FV). School feeding programs have shown promise for increasing FV consumption among young children. However, several aspects of the school cafeteria environment have not been examined regarding their relationship with FV consumption. The purpose of this study was to examine the relationship between noise, selected environmental factors previously explored in the literature (i.e., recess/lunch order, the amount of time allocated for lunch, the presence of a salad bar, and number of FV items offered) and 2nd and 3rd grade students' FV consumption during lunch. A digital photography method was used to assess FV consumption among students across 40 days from 20 schools and environmental exposures, including the noise or sound pressure level of the cafeteria, were assessed during lunch. On average, students in this study consumed 0.35 (SDâ¯=â¯0.31) cups of fruit and 0.24 (SDâ¯=â¯0.29) cups of vegetables. The average noise level in cafeterias was 79.7 (SDâ¯=â¯4.1) Leq DbA (range 70 DbA - 84 DbA). Combined FV consumption was negatively associated with noise exposure (Bâ¯=â¯-0.017; SEâ¯=â¯0.004; Pâ¯<â¯0.001) in hierarchical linear models. Among young children eating in cafeterias, increased noise levels may decrease consumption of fruits and vegetables at the school lunch meal. We hypothesize that increased noise can work in two ways to decrease FV consumption: increased socializing (i.e., talking) and/or decreased hedonic enjoyment of the school lunch meal, however future research is needed to examine these mechanisms and provide causal evidence of this effect.

OBJECTIVE: To examine psychosocial mediators of the effect of a culturally tailored dietary intervention on dietary change among Hispanic/Latina breast cancer survivors. METHODS: Hispanic/Latina breast cancer survivors (n = 70) were randomized to receive either a 12-week theory-based and culturally tailored dietary change program (intervention group, n = 34), or standard-of-care printed recommendations (control group, n = 36) (ClinicalTrials.gov NCT01414062). Fruit/vegetable intake (F/V), % calories from fat, and hypothesized psychosocial mediators were assessed at baseline, 6 and 12 months. Analysis of covariance assessed intervention effects on psychosocial mediators at 6 and 12 months. Mediation analysis using the bootstrap method evaluated the indirect intervention effects on dietary intake at 6 and 12 months through changes in psychosocial mediators at 6 and 12 months. RESULTS: Compared with controls, at 6 and 12 months, the intervention group reported greater improvements in stages of change (P < .001, P < .001, respectively), self-efficacy (P = .009, P = .002, respectively), snack preference for F/snack preference for F/V (P = .045, P = .002, respectively); at 12 months, the intervention group reported a decrease in chance-oriented external locus of control (P = .02). At 6 months, mediation analysis showed that the intervention effect was associated with an increase of 1.0 (95% CI, -0.1-2.4) serving/day of F/V, compared with the control group, although no indirect effect through the hypothesized psychosocial mediators was observed. At 12 months, the intervention was associated with an increase in 0.5 serving/day F/V through improved taste/snack preference for F/V at 6 and 12 months (95% CIs, 0.1-1.3, 0.0-1.4, respectively). CONCLUSIONS: Future programs can target improving taste/snack preference for F/V to promote dietary change in Hispanic/Latina breast cancer survivors.

Social cognitive theory (SCT) is a well-known theory for designing nutrition education and physical activity programs for adolescents. This systematic review aimed to evaluate the efficacy of intervention studies based on SCT in reducing or preventing overweight and obesity in adolescents. An electronic literature search in PubMed-Medline, Web of Science and Scopus was performed to identify intervention studies based on SCT aiming at preventing or reducing obesity in adolescents. All the articles published up to July 2016 were included. Only studies reporting body mass index (BMI) or its variant as one of the outcome measures were included. From 240 initially identified studies, 12 met the eligibility criteria. Seven had moderate or strong study quality. Two of the eight randomized controlled trials (RCT) and two of the four quasi-experimental studies showed significant reduction in BMI among intervened participants compared to control. Impacts on diet and physical activity were mixed, but were mostly not significant. The current systematic review found only weak evidence for the efficacy of SCT-based interventions in treating and preventing obesity in adolescents. Further studies systematically using effective behavior change strategies or techniques, larger population sizes, better measurement tools and more robust designs are warranted for a conclusive judgment.

Background Childhood obesity is a major public health concern and families play an important role. Improving strategies to reach parents and directing tailored nutrition education to them is needed. Purpose To investigate the challenges and facilitators to promoting a healthy environment at home and to identify communication preferences to inform intervention strategies for effectively reaching low-income urban minority families. Procedure Semi-structured focus group interviews were conducted with four groups involving 16 low-income urban parents (94% female; 88% Hispanic/Latino, 12% African American) of elementary school children. Interviews were transcribed and analyzed applying Social Cognitive Theory and using in-vivo coding. Main Findings The most common barriers to parents providing healthy foods to their children were accommodating child preferences and familial opposition. Parents showed intentionality to engage in healthy behaviors, and often shared procedural knowledge for reaching health goals. The analyses of desired communication channels yielded major preferences: tailored information, information provided through multiple mediums, appropriate duration/frequency of messages, and presented from a voice of authority. Conclusion and Implication While parents expressed desires to be healthy, the home food environment presented substantial challenges. Multi-media supports such as workshops, flyers, and text messaging may be useful to facilitate the sharing of information to minimize the tensions between intentionality and reaching desired goals to be healthy. Some parents thought that information received through text messaging could be easily shared and would act as a voice of authority to support child behavior change.

BACKGROUND: Childhood obesity prevention is a pressing issue. Understanding the relationships among eating and physical activity behaviors and potential psychosocial determinants of behavior will help us design more effective interventions. This study aimed to examine such relationships in a large sample of urban elementary school children. METHODS: Fifth grade students in 20 recruited New York City public schools completed a validated questionnaire on six "do more" (fruits and vegetables and physical activity) and "do less" (sweetened beverages, processed packaged snacks, fast food and sedentary behavior) energy balance related behaviors (EBRBs) and psychosocial determinants of behavior from social cognitive and self-determination theories. Correlations among behaviors and hierarchical linear model analyses of the relationship between psychosocial determinants and behaviors were conducted for those with complete data (n = 952). RESULTS: The "do more" and the "do less" behaviors were significantly correlated within categories (p < 0.01). "Do more" food-related behaviors were correlated with physical activity but so were sports drinks, while the "do less" food-related behaviors tended to be correlated to sedentary behavior (p < 0.01). "Do more" behaviors were associated with self-efficacy and habit strength, and "do less" behaviors with outcome expectations, self-efficacy, habit strength, and behavioral intention. CONCLUSIONS: Interventions can address the healthy and less healthy clusters of behaviors together, focusing on strategies to enhance their self-efficacy and habit strength for the "do more" behaviors and outcome expectations to motivate intention to choose fewer "do less" behaviors, along with enhancing self-efficacy and habit. Research can examine these determinants as potential mediators of change in intervention.

Childhood obesity is a complex, worldwide problem. Significant resources are invested in its prevention, and high-quality evaluations of these efforts are important. Conducting trials in school settings is complicated, making process evaluations useful for explaining results. Intervention fidelity has been demonstrated to influence outcomes, but others have suggested that other aspects of implementation, including participant responsiveness, should be examined more systematically. During Food, Health & Choices (FHC), a school-based childhood obesity prevention trial designed to test a curriculum and wellness policy taught by trained FHC instructors to fifth grade students in 20 schools during 2012-2013, we assessed relationships among facilitator behaviors (i.e., fidelity and teacher interest); participant behaviors (i.e., student satisfaction and recall); and program outcomes (i.e., energy balance-related behaviors) using hierarchical linear models, controlling for student, class, and school characteristics. We found positive relationships between student satisfaction and recall and program outcomes, but not fidelity and program outcomes. We also found relationships between teacher interest and fidelity when teachers participated in implementation. Finally, we found a significant interaction between fidelity and satisfaction on behavioral outcomes. These findings suggest that individual students in the same class responded differently to the same intervention. They also suggest the importance of teacher buy-in for successful intervention implementation. Future studies should examine how facilitator and participant behaviors together are related to both outcomes and implementation. Assessing multiple aspects of implementation using models that account for contextual influences on behavioral outcomes is an important step forward for prevention intervention process evaluations.

INTRODUCTION: The benefits of physical activity for health and well-being are well established, yet built environment characteristics in the school neighborhood may constrain students' ability to engage in physical activity and contribute to the considerable variation in physical activity among students at different schools. METHODS: Baseline data from the Food, Health and Choices obesity prevention trial were used to create multilevel linear models of the relationship between fifth-grade students' (n = 952) physical activity and related psychosocial factors and characteristics of the built environment of the school's neighborhood (park access, public transportation density, total crime, and walkability), controlling for age and body mass index z scores. RESULTS: Total crime was inversely associated with boys' light physical activity duration (ß = -0.189; P = .02) and behavioral intention for physical activity (ß = -0.178; P = .03). Boys' habit strength for physical activity was positively associated with public transportation density (ß = 0.375; P = .02) and negatively associated with total crime (ß = -0.216; P = .01), explaining 67% of between-school variation. Girls' frequency of light physical activity was positively associated with park access (ß = 0.188; P = .04). Built environment characteristics explained 97% of the between-school variation in girls' self-efficacy in walking for exercise. CONCLUSIONS: Characteristics of the built environment surrounding schools were associated with and explain between-school variation in students' physical activity and several theory-based psychosocial factors. Partnerships between public health practitioners, policy makers, and school administrators may be warranted to shape the school neighborhood, specifically to decrease crime rates and increase park access, to encourage physical activity in youth.

This study investigates the link between process evaluation components and the outcomes of a school-based nutrition curriculum intervention, 'Choice, Control and Change'. Ten New York City public middle schools were recruited and randomly assigned into intervention or control condition. The curriculum was to improve sixth to seventh grade students' energy balance related behaviors, based on social cognitive and self-determination theories, and implemented during the 2006-2007 school year (n = 1136). Behaviors and psychosocial variables were measured by self-reported questionnaires. Process components were evaluated with classroom observations, teacher interviews, and a student questionnaire. Using 'Teacher Implementation' (dose delivered) and 'Student Reception' (dose received) process data; intervention group was further categorized into medium- and high-implementation groups. Analysis of covariance revealed that, compared with control group, only high-implementation group showed significant improvement in students' behavior and psychosocial outcomes. Hierarchical linear models showed that 'Teacher Implementation' and 'Student Reception' significantly predicted students' sweetened beverage outcomes (P < 0.05). 'Student Satisfaction' was also greater when these implementation components were higher, and significantly associated with behavior and psychosocial outcomes (P < 0.05). Implementation process influenced the effectiveness of the 'Choice, Control and Change' intervention study. It is important to take into account the process components when interpreting the results of such research.

OBJECTIVE: To determine the degree of dietary adherence or change in eating patterns, and demographic, psychosocial and study characteristics associated with adherence, in the Comparing Healthy Options in Cooking and Eating (CHOICE) Study. DESIGN: Randomized controlled trial where women were randomized to one of three eating patterns: (i) Whole Foods, plant-based, macrobiotic-style (n 22); and Moderate Fat with (ii), and without (iii), 10 g of ground flaxseed added daily, which were combined (n 49). SETTING: A year-long intervention based on social cognitive theory, consisting of twenty-four class sessions involving hands-on cooking classes and behavioural sessions. Monthly 24 h food recalls were obtained and a psychosocial questionnaire was administered at baseline, 6 and 12 months. SUBJECTS: Healthy, free-living, postmenopausal women. RESULTS: A non-adherence score measuring all food servings out-of-compliance with eating pattern recommendations was specifically designed for the present study. Non-adherence scores decreased significantly (P < 0·05) in both groups to about 65 % during the adoption phase (first 4 months) and remained so during the 8-month maintenance period. Class attendance of the Moderate Fat group showed a trend towards significance as a predictor of adherence (P = 0·063). None of the other predictors (e.g. demographic and psychosocial factors) in a longitudinal regression model were significant. CONCLUSIONS: Postmenopausal women were able to adopt and maintain significant changes in their eating patterns, including those on a demanding, near-vegetarian eating plan, suggesting that behavioural interventions with a healthy free-living population can be effective. The non-adherence score developed for the study provides an example of a means for evaluating eating pattern adherence to a dietary intervention.

Parents influence their child's eating behavior and attitudes directly as food providers and indirectly through their parental feeding styles and feeding concerns and practices. Chinese American parents' practices are likely influenced by culture. The objective of this study was to explore the relationships between parental perceptions, feeding practices, feeding styles, level of parental acculturation (LPA), and child weight status via a self-administered questionnaire. This survey study involved a convenience sample of 712 individuals who were parents of 5- to 10-year old children attending Chinese language after-school programs. The prevalence of overweight was 11.5% and obesity was 11.1%. LPA was not directly predictive of child overweight in multiple regression but from categorical data, Chinese American parents tended to use indulgent (33.2%) and authoritarian (27.9%) feeding styles, with the former increasing with acculturation and the latter decreasing. Indulgent parents had more than expected overweight and obese children, and authoritarian and authoritative parents, fewer. LPA was negatively predictive of pressure to eat healthy foods (p < .01), which was negatively correlated with child weight status (p < .01). LPA was also independently positively correlated to responsiveness to child needs (p < .01), monitoring of child intake (p < .01), and perceived responsibility for child feeding. Parental perceptions and concerns about child weight were predictors of child weight. Consequently, parental concerns and responsiveness to child needs without also encouragement (demandingness) to eat healthy foods (indulgent feeding style) may promote overweight. The authoritative parental feeding style may contribute to children having healthy weights and therefore healthy lives.

INTRODUCTION: The incidence of infants who are large-for-gestational-age (LGA) is on the rise in China, and its detrimental effects on health have received increasing attention. Diet-based interventions have the potential to reduce adverse birth outcomes, particularly in decreasing the occurrence of LGA infants. We aim to evaluate the effect of lipid-focused diet education based on the theories of behaviour change in pregnant women on maternal and offspring outcomes through a randomised controlled trial. METHODS AND ANALYSIS: We have designed an open-label, parallel, multicentre randomised controlled trial in collaboration with three hospitals in Beijing, China.Pregnant women will be recruited before reaching 12 weeks of gestation and will be randomised in a 1:1:1 ratio into three arms: (1) online education arm, (2) pregnancy nutrition checklist and 'one-page flyer' arm and (3) routine antenatal education. The primary outcome LGA will be recorded at birth. Demographic information, physical activity, sleep and medical history will be collected through questionnaires and case cards prior to enrolment. Questionnaires will also be used to collect dietary behaviours and psychosocial factors of pregnant women at enrolment, at 24-28 weeks and 34-36 weeks of gestation. Additionally, information on breastfeeding and complementary food supplementation for infants and young children will be obtained through questionnaires. Physical development indicators of children and taste tests will be assessed 3 years after delivery. ETHICS AND DISSEMINATION: The study has received ethical approval from the Capital Medical University Ethics Committee and other collaborating study centres. Informed consent will be introduced to pregnant women, and their consent will be obtained. The findings will be reported in relevant national and international academic conferences and peer-reviewed publications. TRIAL REGISTRATION NUMBER: ChiCTR2300071126.

Diet and physical activity guidelines for cancer survivorship are less likely to be followed by populations of minority cancer survivors, such as Latina/Hispanic women, compared to non-Hispanic White women. It is important to understand psychosocial mechanisms that may increase adherence to healthy lifestyle habits, especially in populations at risk for poorer cancer outcomes. This cross-sectional study examined the relationships between overall social support (SS) and SS from three sources (family, friends, and significant other) with diet (fruit and vegetables, fat, energy density, and diet quality), and moderate-to-vigorous physical activity (MVPA) behaviors in Latina/Hispanic women with a history of breast cancer (n = 85; M age = 55.2; SD = 9.2). Linear regression models and odds ratios were used to examine associations and adjusted for age, income, and acculturation. Family, significant other, and total SS were positively related to total fruit and vegetable intake but SS from friends was not. Higher levels of SS from all sources were each related to a low energy density diet. A higher quality diet was only related to SS from family. SS was not related to fat intake or MVPA. Higher SS from family and a significant other were associated with higher odds of meeting the fruit/vegetable guidelines; (family, OR = 3.72, 95% CI [1.21, 11.39]; significant other, OR = 3.32, 95% CI [1.08, 10.30]). Having more SS from family or a significant other may contribute to Latina/Hispanic women breast cancer survivors meeting national guidelines for a diet high in fruits and vegetables and low in energy density.
RESUMO
OBJECTIVE: The primary objective of this study was to develop and validate a Social Cognitive Theory-based instrument to identify psychosocial factors that influence diet and physical activity among Chinese children aged 10-12 years. DESIGN: This is a cross-sectional study, with data collected from questionnaires. SETTING: Two elementary schools in Beijing, China. PARTICIPANTS: Fourth to sixth-grade students (N = 1,486) aged 10-12 years were recruited. VARIABLES MEASURED: Gender, height, weight, nation, and grade were collected. Energy-balanced eating behaviors and their related sociopsychological factors were surveyed. ANALYSIS: Confirmatory factor analysis, Pearson correlations, Cronbach α index, and mediation analysis were used. RESULTS: (1) Confirmatory factor analysis revealed a 6-factor solution (51 items) and all factor loadings > 0.32, indicating that the model fitness was acceptable. (2) All correlation coefficients are statistically significant. All of the Cronbach α indexes were > 0.65, indicating acceptable reliability. (3) The mediating effect of goal intention and outcome expectations between self-efficacy and habit strength was statistically significant (P < 0.01), verifying the theory structure. CONCLUSIONS AND IMPLICATIONS: This questionnaire exhibits good internal consistency, reliability, and structural validity. It can be effectively employed to investigate energy-balanced eating behaviors related to the Social Cognitive Theory in Chinese children.

Introduction: This study aimed to explore the feasibility and acceptability of implementing a worksite diabetes prevention program-Beat Diabetes-on the basis of a plant-based diet and encouragement of physical activity. Methods: This was a mixed-methods pilot study using a 1-group pretestâpost-test design. The participants were university employees. A 13-week group-based intervention adapted from the Diabetes Prevention Program to emphasize a plant-based diet and on the basis of the Health Action Process Approach. Program implementation and participant acceptability were assessed through surveys, weekly documentation of the process, and individual interviews. Consumption of healthy and less healthy plant-based foods and animal-based foods, physical activity, and Health Action Process Approachâbased psychosocial determinants were measured through questionnaires before and after the program, as was blood glucose. Weights were measured weekly. Results: A total of 14 participants were enrolled, with 93% retention. Program implementation was feasible and highly acceptable to participants and also resulted in significant improvements in weight, healthy relative to less healthy plant-based and animal-based foods, vigorous physical activity, blood glucose, and psychosocial determinants of behavior change. Conclusions: On the basis of our pilot study, conducting a worksite plant-based diabetes prevention program was feasible and acceptable and elicited positive changes in physiologic, behavioral, and psychosocial variables related to the risk of diabetes.
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.

The purpose of this study is to conduct validity and reliability testing of a new instrument, the Preferences and Self-Efficacy of Diet and Physical Activity Behaviors Questionnaire for Latina Women (PSEDPALW), which is for women who identify as Latina and are breast cancer survivors. PSEDPALW measures preferences and self-efficacy for four behaviors: physical activity (PA), fruit and vegetable (FV) intake, dietary fat (DF) intake, and added sugar (AS) intake (eight scales in total). Validity testing was conducted through an expert panel review and a cognitive interviewing focus group (n = 4). Reliability was tested via internal consistency reliability (n = 118) and test-retest reliability (n = 30). Validity testing was used to refine PSEDPALW. Reliability testing was conducted on three versions with 104, 47, and 41 items. PA scales had acceptable Cronbach's α (>0.70) but low ICC (NS). FV and DF scales had acceptable Cronbach's α (>0.70), with preferences for the shorter (47- and 41-item) versions (Cronbach's α < 0.70), and all scales had moderate ICC (p < 0.05, except the FV scale on the 104-item version (p = 0.07)). The AS preferences scale had Cronbach's α < 0.70, with self-efficacy > 0.70 for all versions and ICC moderate for all versions (p ≤ 0.01). PSEDPALW may be useful to assess diet and physical activity preferences and self-efficacy in theory-based diet and physical activity interventions in women who identify as Latina and are breast cancer survivors.

In the United States, many children who come from low-income backgrounds and experience food insecurity do not take and eat school lunch, despite it being a nutritious meal. Teachers could play a role in encouraging students' consumption of school lunch; however, teachers in America are traditionally uninvolved in the lunch period. The purpose of this research was to understand the resources kindergarten through twelfth grade (K-12) teachers need to encourage students to take and eat school lunch. Two data collection workshops and semi-structured follow-up interviews were conducted with K-12 teachers. The workshops and interviews were recorded, transcribed, and analyzed for salient themes. Ten teachers participated in the workshops and six teachers participated in the follow-up interviews. In general, teachers believe school meals are essential for students' focus and behavior in the classroom. However, to encourage students to take and eat school lunch, teachers need support and resources. From the workshops and interviews, three themes emerged: (1) improvements in the food quality; (2) school community support; and (3) professional development. The data suggests professional development is the greatest resource teachers need, as professional development can enhance teachers' motivation to advocate for better food quality and engage school community support. Greater teacher involvement in school lunch could lay the groundwork for future healthier generations.
