RESUMO

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.

RESUMO

The purpose of this study is to develop a novel framework that outlines the system required to implement scratch cooking in school kitchens. The data used in this study were 57 interviews with key stakeholders during the Return to Scratch Cooking Pilot that occurred in two New York City school kitchens in 2018-2019 and made significant modifications to many aspects of the existing school food system. The guiding framework for the data analysis was Meadows's Intervention Level Framework. Intervention Level Framework describes analyzing systems by examining five layers: (1) paradigm shift, (2) goals, (3) system structure (4) feedback and delays, and (5) structural elements. It also provides a framework for describing a system by defining its elements, interconnections, and purpose. Data analysis revealed four elements of the school food system: ingredients and recipes, kitchen, cooking, and the community. The interconnections that played a role in each of these elements were policies, practice, people, and promotion. Together, these four elements and four interconnections comprise the Scratch Cooked School Food framework, which has the purpose of being a tool for researchers and practitioners to utilize when planning, implementing, and evaluating scratch cooking in the school food environment.

RESUMO

BACKGROUND: Although largely preventable through diet management and topical fluoride use, early childhood caries (ECC) often progresses to severity that necessitates surgical repair. Yet repair often fails to mitigate caries progression. Needed is an effective behavioral intervention to address underlying behavioral causes. METHODS: This randomized controlled trial will evaluate the efficacy of a behaviorally focused, family-centered intervention, the MySmileBuddy Program (MSB Program), to reduce ECC progression in high-risk preschoolers in New York City. Recruitment will target 858 children ages 24-71 months with ECC and their parents from primary care medical and dental clinics. The study aims to assess the MSB Program's efficacy to: (1) decrease ECC progression measured 12-months post-randomization; and (2) enhance adoption of a low cariogenic diet and twice-daily fluoridated toothpaste use compared to control group. Potential causal pathways (mediators and moderators) will be explored. The MSB Program equips community health workers (CHWs) with an app that facilitates multilevel risk assessment and provides motivational interviewing-based counseling to inform parents about the caries process, develop personalized goals, and create family-level action plans to achieve targeted behaviors. Social support from CHWs (4 interactions during the 6-month intervention, supplemented by up to 4 in-person/remote contacts throughout the 12-month study period, based on need) is bolstered by automated text messages. Participants will be randomized to a Control Group (paper-based educational handout plus toothbrushes and fluoridated toothpaste for the child) or Intervention Group (MSB Program, two tooth-brushing observations with feedback and instruction, and toothbrushes and toothpaste for the entire family). All children will receive visual ICDAS dental examinations and parents will complete study measures at baseline and 12-months. An incentive up to $150 plus round-trip transit cards ($5.50 value) will be provided. DISCUSSION: This study hypothesizes that the MSB Program can reduce ECC progression in a high-risk population. Sufficient incentives and a focus on establishing rapport between participants and CHWs are anticipated to mitigate recruitment and retention challenges. If successful, this study will advance the long-term goal of reducing pediatric oral health disparities by demonstrating the efficacy of an acceptable and feasible intervention that shifts attention from dental repair to behavioral risk mitigation. TRIAL REGISTRATION: Trial registration was completed on 4/13/2021 through the U.S. National Library of Medicine ClinicalTrials.gov website (Identifier: NCT04845594).

RESUMO

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.

RESUMO

Evidence of the benefits of culinary nutrition education is growing in the literature. Culinary nutrition education programs are naturally experiential, social, skills-based, and effective in improving nutrition-related beliefs, knowledge, and behaviors. In this article, we explore a set of motivational experiences in culinary nutrition education that have been identified as "drivers" of behavior change. These drivers emerged from 20 years of implementation and evaluation of hands-on cooking programs across the life span in more than 30 states within the United States. From these drivers, we developed a framework to guide both new and existing programs that can be best designed to motivate behavior change. These frameworks add value to the work of culinary nutrition educators and will inform and support future culinary nutrition education programs. In future research, health educators implementing skills-based health promotion programs in diverse settings can test the application of this framework to determine its relevance in broader areas.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Ultra-processed foods (UPF) are ubiquitous in the modern-day food supply and widely consumed. High consumption of these foods has been suggested to contribute to the development of obesity in adults. The purpose of this review is to present and evaluate current literature on the relationship between UPF consumption and adult obesity. Cross-sectional studies (n = 9) among different populations worldwide show a positive association between UPF consumption and obesity. Longitudinal studies (n = 7) further demonstrate a positive association between UPF consumption and development of obesity, suggesting a potential causal influence of UPF consumption on obesity risk. However, only one randomized controlled trial has tested the causality of this association. The study included in this review found greater energy intake and weight gain with consumption of a high UPF diet compared to a high unprocessed food diet. The potential mechanisms by which UPF increase the risk of obesity include increased energy intake due to increased sugar consumption, decreased fiber consumption, and decreased protein density; however, more research is needed. Overall, the evidence identified in the current review consistently support a positive relation between high UPF consumption and obesity. While there is a need for more experimental research to establish causality and elucidate the mechanisms, the sum of the evidence supports a need for research on treatment modalities that include reductions in UPF consumption for the management of adult obesity.

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

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.

RESUMO

BACKGROUND: The COVID-19 pandemic created barriers to participation in school meals. As a result, many students may have missed out on school meals. The objectives of this study are (1) to compare the number of school meals served by New York State public schools during the first spring and summer of the COVID-19 pandemic to the number served before the COVID-19 pandemic, and (2) to determine relationships between the number of meals served and the levels of school district need and urbanicity. METHODS: This study is a secondary analysis of administrative data. The percentage change in the number of school breakfasts and lunches served was calculated for each month and by school district need level and urbanicity level. RESULTS: The number of school meals served decreased during the first spring of the pandemic compared to the spring of the previous school year (-43% in April, -51% in May), while the number of school meals served increased during the first summer of the pandemic compared to the summer of the previous school year (+92% in July, +288% in August). CONCLUSIONS: Waivers may provide flexibility to increase participation in school meals, especially during the summer.

RESUMO

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.

RESUMO

During the COVID-19 pandemic, significantly fewer of New York City's (NYC's) 1.1 million public school children participated in emergency grab-and-go meals-heightening the risk of inadequate nutrition security for many of NYC's most vulnerable residents. This study sought to examine student families' facilitators and barriers to participation in the grab-and-go meal service and their experiences with pandemic-electronic benefit transfer (P-EBT) funds, a cash benefit distributed when schools were closed. We recruited 126 parents of children in NYC public schools who had participated in the grab-and-go service. Using opened-ended questions, we interviewed 101 parents in 25 1-h online focus groups. We identified four main themes which broadly impacted school meal participation: communication, logistics, meal appeal, and personal circumstances. Key facilitating subthemes included clear communication, ease of accessing sites, and high variety. Key sub-themes negatively impacting participation included limited communication and low meal variety. Accurate, timely communication; easily accessible distribution locations; and convenient distribution times could have increased participation and satisfaction. For P-EBT, parents welcomed the funds and used them readily, but some experienced difficulties obtaining payments. The simultaneous inclusion of community-based research in the evaluation of emergency feeding programs could improve future outcomes for school meal participation and electronic benefits.
