Reliability and Validity of a Theory-Based Determinants of Eating and Physical Activity Behaviors Questionnaire for Chinese Elementary School Children.

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.

Lipid-focused dietary education intervention in pregnant women: study protocol for an open-label, parallel, randomised, intervention study addressing adverse pregnancy outcomes in China.

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.

Pilot Study of the Feasibility of a Worksite Plant-Based Diabetes Prevention Program.

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 pretest‒post-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 Approach‒based 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.

Mi Vida Saludable: Content Validity and Reliability of The Preferences and Self-Efficacy of Diet and Physical Activity Behaviors Questionnaire for Latina Women (PSEDPALW) for Cancer Survivors.

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.

Diet quality, ultra-processed food consumption, and quality of life in a cross-sectional cohort of adults and teens with celiac disease.

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.

Position of the Society for Nutrition Education and Behavior: Nutrition Educator Competencies for Promoting Healthy Individuals, Communities, and Food Systems: Rationale and Application.

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.

Teachers' Resources to Support School Lunch: Professional Development Is Warranted.

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.

Developing a Diet and Physical Activity Intervention for Hispanic/Latina Breast Cancer Survivors.

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.

Associations Between Acculturation and Weight, Diet Quality, and Physical Activity Among Latina Breast Cancer Survivors: The ¡Mi Vida Saludable! Study.

BACKGROUND: Among Latinos, greater acculturation to the United States (US) is associated with risk of obesity and obesity-related comorbidities. Less is known about the associations between acculturation and obesity-related modifiable risk factors, such as diet quality and physical activity (PA) among Latina breast cancer survivors. OBJECTIVE: The aim of this study was to explore associations between acculturation and weight status, diet quality, and PA among Latina breast cancer survivors. DESIGN: This is a cross-sectional secondary analysis of baseline data on demographic and clinical characteristics, acculturation, anthropometric measures, diet quality, and PA collected from Latina breast cancer survivors enrolled in the ¡Mi Vida Saludable! (My Healthy Life) behavioral diet and PA intervention trial. PARTICIPANTS/SETTING: Participants were Latina women (n = 167) residing in New York City, with a medical history of stage 0 to III breast cancer, no evidence of recurrent or metastatic disease, and at least 90 days post cancer treatment who participated in the ¡Mi Vida Saludable! randomized controlled trial between July 2016 and October 2018. MAIN OUTCOME MEASURES: Acculturation status was measured by the Short Acculturation Scale for Hispanics score, language preference, place of birth, and duration of US residence. Weight, height, and waist and hip circumferences were measured at an in-person clinic visit. Diet information was collected via 3 telephone-based 24-hour dietary recalls and PA information was collected via staff administered 7-day recalls. STATISTICAL ANALYSES PERFORMED: Linear regression models examined associations between acculturation and weight status, diet quality, and PA. RESULTS: Based on the Short Acculturation Scale for Hispanics acculturation score, more acculturated compared with less acculturated Latinas were younger in age, more educated, and had higher annual household incomes (all, P < .05). Compared with Spanish-speaking Latinas, English-speaking Latinas had larger waist circumference (103 vs 96.1 cm; P = .01) and poorer-quality diets (Healthy Eating Index 2015 scores, 57.3 vs 71.5; P < .001). Greater levels of acculturation were also associated with higher levels of leisure walking at a moderate-to-vigorous intensity (265.8 vs 179.0 min/wk; P =.04). CONCLUSIONS: Greater levels of acculturation were associated with higher central obesity and poorer-quality diets. Future lifestyle modification trials tailored to the unique role of acculturation on adopting behavior change recommendations is a promising next step in this line of research.

Cognitive Functioning and Health in Hispanic/Latina Breast Cancer Survivors.

We examined the effect of waist-to-hip ratio, body mass index (BMI), diet, and physical activity on cognitive functioning among Hispanic/Latina breast cancer survivors in a cross-sectional design study. Participants were 54 Hispanic/Latina breast cancer survivors and completed the NIH Toolbox Cognition Battery. Linear Regression Models tested if statistically significant correlations held with covariates. After controlling for covariates, moderate and hard physical activity were not associated with cognition. However, very hard physical activity was positively associated with faster processing speed (ß = 0.56, p < 0.001) and composite cognition score (ß = 0.36, p < 0.05). Total time (minutes) of moderate to very hard physical activity was positively associated with cognitive flexibility (ß = 0.52, p < 0.001). Total caloric intake was positively associated with episodic memory (ß = 0.35 p < 0.05). BMI and WHR were not associated with cognition. These findings showed positive association with engagement in more MVPA and harder intensity physical activity to better cognitive functioning among Hispanic/Latina breast cancer survivors.ClinicalTrials.gov NCT02780271.

Soda Consumption Among Mexican Construction Workers in the Context of the Sugar-Sweetened Beverage Tax.

This study explored the psychosocial determinants of consumption of soda and other taxed sugar-sweetened beverages (SSBs) in Mexican construction workers (CWs) and whether consumption changed as a result of the 2014 SSB tax. We conducted a qualitative case study involving in-depth interviews and focus groups (FGs) with 30 Mexican CWs; supplemented with descriptions of the food and beverages consumed during lunch breaks. We used NVivo 10 to classify information according to the analysis categories, primarily informed by the Reasoned Action Approach (RAA). CWs reported not having changed their consumption of soda and other taxed SSBs as a result of the SSB tax, despite the price increase and "knowing" the potential negative consequences of soda drinking. The most important determinants of soda consumption are a deep-seated social norm of soda drinking and use of soda drinking as part of their professional identity; their likeness for soda; a wide availability of soda in their environments; and a low perceived behavioral control (because they thought themselves as addicted to it). Participants indicated that the best way for them not to consume soda would be if it were not available. These findings lend support for the tight regulation of the availability of SSBs. To have a meaningful impact on these consumers, the SSB tax may need to be much higher. Policy-level interventions should be coupled with interventions at the individual and community levels that aim at denormalizing soda consumption, create new meanings in relation to water consumption, and develop behavioral control to decrease soda consumption.

¡Mi Vida Saludable! A randomized, controlled, 2 × 2 factorial trial of a diet and physical activity intervention among Latina breast cancer survivors: Study design and methods.

BACKGROUND: Most Latina breast cancer survivors do not meet diet and physical activity (PA) guidelines for cancer survivors and effective lifestyle interventions to adopt and maintain these recommendations are limited, especially among underserved populations. Here we describe the design, methods and enrollment of a 2 × 2 factorial-designed trial testing the separate effects of the ¡Mi Vida Saludable! (My Healthy Life!) intervention program on changes in diet and PA behaviors among Latina breast cancer survivors. METHODS: Latinas with a history of stage 0-III breast cancer, no evidence of recurrent/metastatic disease, and > 90 days post-treatment were primarily identified via cancer registries and physician referral. Participants were randomized to four arms: 1) 4 weeks of in-person group sessions plus 11 months of eHealth communication, 2) in-person group sessions alone, 3) eHealth alone, or 4) control. All participants received a Fitbit to self-monitor PA. Assessments at baseline, 6 and 12 months include diet, PA, anthropometrics, predictors and mediators of behavior change, psychosocial and quality of life outcomes, and blood draw. RESULTS: Of 884 women screened between January 2016 and September 2018, 27% were eligible. Primary reasons for ineligibility included not being willing/able to participate due to work/life responsibilities, health reasons, or transportation. Of 241 eligible women, 167 completed baseline assessment and enrolled. CONCLUSIONS: We successfully enrolled a diverse group of breast cancer survivors representing more than 15 Latin American nationalities to a diet and physical activity trial. If effective, the ¡Mi Vida Saludable! program can be implemented by community groups and medical centers. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02780271, registered May 2016.

A secondary analysis of maternal ultra-processed food intake in women with overweight or obesity and associations with gestational weight gain and neonatal body composition outcomes.

BACKGROUND: This study is an observational secondary analysis of the Lifestyle Intervention for Two (LIFT) randomised controlled trial data. There is a paucity of data related to mechanisms of health effects and dietary intake of ultra-processed foods (UPF). Earlier studies demonstrate associations between greater UPF intake and weight gain. The purpose of the study was to describe associations among maternal UPF intake with gestational weight gain (GWG) and neonatal body composition. MATERIAL AND METHODS: Women with overweight or obesity (n=156) and offspring (n=126) with complete energy intake, anthropometrics and body composition measures were selected. Maternal weights and diet recalls (Automated Self-Administered 24) were measured at weeks 14 and 35 gestational age (GA). Body composition was assessed by infant quantitative magnetic resonance (infant-QMR) and air displacement plethysmography (ADP) at birth. Dependent variables were GWG and neonatal fat mass, fat-free mass, and lean mass at birth; covariates were dietary, socioeconomic and biological. Stepwise linear regressions were used to test associations. RESULTS: Highest quartile of percentage of energy intake from UPF (PEI-UPF) was not significantly correlated with maternal GWG (p=0.215), infant QMR fat (p=0.816) and lean mass (p=0.423) or ADP fat (p=0.482) or fat-free mass (p=0.835). CONCLUSIONS: While no significant associations with UPF were observed in this smaller size cohort, further investigations would be justified in larger cohorts on the relationships of maternal UPF intake and GWG and offspring outcomes. Clinical Trial NCT01616147.

A Cooking-Based Intervention Promotes Gluten-Free Diet Adherence and Quality of Life for Adults with Celiac Disease.

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.

Urban Preschool Teachers' Nutrition Beliefs, Mealtime Practices, and Associations With Training.

OBJECTIVE: To examine preschool teachers' nutrition-related beliefs and practices and explore associations with Eat Well Play Hard in Child Care Settings (EWPHCCS) training. DESIGN: Causal-comparative study using a post-only, cross-sectional survey exploring teachers' nutrition-related beliefs and mealtime practices. SETTING: New York City preschools serving low-income children. PARTICIPANTS: Ethnically diverse preschool teachers (n = 660), 420 (response rate 90.4%) with EWPHCCS training and 240 (response rate 57.1%) without training. MAIN OUTCOME MEASURES: Teachers' beliefs about their preschool nutrition environments and compliance with recommended mealtime practices. ANALYSIS: Analysis of variance and hierarchical linear modeling. RESULTS: Overall, teachers reported generally favorable beliefs about their preschool nutrition environments and compliance with recommended mealtime practices. EWPHCCS teachers reported more favorable scores on beliefs and practices than nontrained teachers. Teachers who were not parents reported significantly lower scores on beliefs and practices than teachers who were parents. White teachers and the least experienced teachers reported the lowest scores on compliance with mealtime practices. CONCLUSIONS AND IMPLICATIONS: EWPHCCS training was associated with higher scores on both beliefs and practices. However, school-level policy and leadership may also be important. Providing specific training for preschool directors and addressing food quality may further improve teachers' nutrition-related attitudes, beliefs, and practices.

In Defense of Food Curriculum: A Mixed Methods Outcome Evaluation in Afterschool.

Background. Highly processed foods are inexpensive and abundant in our food supply, nutritionally poor, and disproportionately marketed to minority youth. This study is part of a curriculum development project to develop, implement, and evaluate the In Defense of Food (IDOF) curriculum designed to increase intake of whole/minimally processed foods and decrease intake of highly processed foods in youth. Aims. This pilot outcome evaluation was undertaken to assess initial effectiveness and to provide an in-depth understanding of changes in behavioral outcomes and psychosocial mediators. Methods. We used an explanatory mixed method approach, including a single-arm pretest-posttest of intervention effect, followed by a food rules assessment and in-depth interviews to describe participant responses to the intervention in more detail. The study was conducted in three afterschool classrooms in urban low-income neighborhoods with 32 multiethnic middle-school youth, receiving 10 weekly 2-hour sessions. Results. Two weeks postintervention, there was a large positive significant increase in whole/minimally processed food intake (p < .01; d = 0.59) and a small decrease in consumption of highly-processed foods (p = ns; d = 0.06), compared with baseline. Significant increases in psychosocial mediators: Self-efficacy and positive outcomes expectations were seen; others were not significant but changed in the desired direction. Qualitative assessments suggest that the intervention promoted skill building, but environmental barriers made these difficult to use. Discussion. The IDOF curriculum may be most effective for promoting consumption of fruits and vegetables, rather than decreasing intake of highly processed foods. In addition, in this young age-group, short actionable food rules may support self-regulation and behavior change. Conclusion. Among adolescent students in low-income urban neighborhoods, the IDOF afterschool curriculum may help promote self-efficacy and positive outcome expectancies and increase fruit and vegetable intake. Focusing on food processing and using "Food Rules" may be promising to elicit behavior change in youth; however, greater supports are needed to overcome social and environmental barriers.

Feasibility, Acceptability, and Short-term Behavioral Impact of the MySmileBuddy Intervention for Early Childhood Caries.

OBJECTIVES: To evaluate acceptability, feasibility, and short-term behavioral impact of an early childhood caries (ECC) intervention. METHODS: Predominantly low-income Hispanic parent/child (2-6 years) dyads attending a busy pediatric dental clinic in New York City completed a single administration of the iPad-based technology-assisted education, goal-setting, and behavior change MySmileBuddy program. Self-reported behavior change was assessed via telephone survey one month post-intervention. RESULTS: Of 113 parent/child dyads approached, 108 (95.6%) participated and all completed MySmileBuddy in its entirety. Over 96% (n = 76) of 79 parents reached for follow-up recalled MySmileBuddy; 63.3% (n = 50) recalled their diet-and/or oral hygiene-related behavioral goal; and 79.7% (n = 79) reported taking action to initiate behavior change. CONCLUSIONS: Findings suggest that MySmileBuddy was feasibly implemented in a busy clinic, acceptable to this high-risk population, and effectively promoted preliminary ECC-related behavior changes. Larger, long-term studies are warranted to further investigate the impact of the MySmileBuddy program.

Cafeteria noise exposure and fruit and vegetable consumption at school lunch: A cross-sectional study of elementary students.

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 (SD = 0.31) cups of fruit and 0.24 (SD = 0.29) cups of vegetables. The average noise level in cafeterias was 79.7 (SD = 4.1) Leq DbA (range 70 DbA - 84 DbA). Combined FV consumption was negatively associated with noise exposure (B = -0.017; SE = 0.004; P < 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.

Food, Health, & Choices: Curriculum and Wellness Interventions to Decrease Childhood Obesity in Fifth-Graders.

OBJECTIVE: To evaluate Food, Health, & Choices, two 10-month interventions. DESIGN: Cluster-randomized, controlled study with 4 groups: curriculum, wellness, curriculum plus wellness, and control. SETTING: Twenty elementary schools (5/group) in New York City. PARTICIPANTS: Fifth-grade students (n = 1,159). At baseline, 44.6% were at the ≥85th body mass index (BMI) percentile for age and 86% qualified for free or reduced-price lunch. INTERVENTION: Curriculum was 23 science lessons based on social cognitive and self-determination theories, replacing 2 mandated units. Wellness was classroom food policy and physical activity bouts of Dance Breaks. MAIN OUTCOME MEASURES: For obesity, age- and sex-specific BMI percentiles were used (anthropometric measures). The researchers also employed 6 energy balance-related behaviors and 8 theory-based determinants of behavior change (by questionnaire). ANALYSIS: Pairwise adjusted odds in hierarchical logistic regression models were determined for >85th BMI percentile. Behaviors and theory-based determinants were examined in a 2-level hierarchical linear model with a 2 × 2 design for intervention effects and interactions. RESULTS: Obesity showed no change. For behaviors, there was a negative curriculum intervention change in physical activity (P = .04). The wellness intervention resulted in positive changes for sweetened beverages frequency (P = .05) and size (P = .006); processed packaged snacks size (P = .01); candy frequency (P = .04); baked good frequency (P = .05); and fast food frequency (P = .003), size (P = .01), and combo meals (P = .002). Theory-based determinants demonstrated no change. CONCLUSIONS AND IMPLICATIONS: The findings of the lack of a decrease in obesity, behavior changes only for the wellness intervention, and no changes in theory-based determinants warrant further research.

Context Considerations for Developing the In Defense of Food Nutrition Education Curriculum.

OBJECTIVE: To examine perceptions of teachers and afterschool program staff related to the positive aspects and challenges of afterschool education for youth to guide the development of the "In Defense of Food" nutrition education curriculum. METHODS: Semi-structured in-depth interviews with a convenience sample of teachers and afterschool program staff experienced serving at-risk youth were conducted in New York, NY. They were audio-recorded, transcribed verbatim, and analyzed using inductive summative content analysis to identify, count, and compare themes. RESULTS: Interviews (n = 12) generated 2 meta-themes (Pedagogical Elements for Successful Learning and Pragmatic Considerations for hosting health promotion programs in the afterschool context). Learner-centered and tailored approaches and building social connection were considered important for fostering learning in the afterschool context. CONCLUSIONS AND IMPLICATIONS: This study emphasizes the importance of considering pedagogical elements related to delivery that minimizes didactic instruction and focuses on learner-centered approaches. Further research is needed to compare outcomes and process measures common approaches used in designing nutrition education curricula with those that have been described in this study.
