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

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

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: 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.

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

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

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

It is the position of the Academy of Nutrition and Dietetics, School Nutrition Association, and Society for Nutrition Education and Behavior that comprehensive, integrated nutrition programs in preschool through high school are essential to improve the health, nutritional status, and academic performance of our nation's children. Through the continued use of multidisciplinary teams, local school needs will be better identified and addressed within updated wellness policies. Updated nutrition standards are providing students with a wider variety of fruits, vegetables, and whole grains, while limiting sodium, calories, and saturated fat. Millions of students enjoy school meals every day in the US, with the majority of these served to children who are eligible for free and reduced-priced meals. To maximize impact, the Academy, School Nutrition Association, and Society for Nutrition Education and Behavior recommend specific strategies in the following key areas: food and nutrition services available throughout the school campus, nutrition initiatives such as farm to school and school gardens, wellness policies, nutrition education and promotion, food and beverage marketing at school, and consideration of roles and responsibilities.

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

Variability in individuals' responses to interventions may contribute to small average treatment effects of childhood obesity prevention interventions. But, neither the causes of this individual variability nor the mechanism by which it influences behavior are clear. We used qualitative methods to characterize variability in students' responses to participating in a childhood obesity prevention intervention and psychosocial characteristics related to the behavior change process. We interviewed 18 students participating in a school-based curriculum and policy behavior change intervention. Descriptive coding, summary, and case-ordered descriptive meta-matrices were used to group participants by their psychosocial responses to the intervention and associated behavior changes. Four psychosocial phenotypes of responses emerged: (a) Activated-successful behavior-changers with strong internal supports; (b) Inspired-motivated, but not fully successful behavior-changers with some internal supports, whose taste preferences and food environment overwhelmed their motivation; (c) Reinforced-already practiced target behaviors, were motivated, and had strong family support; and (d) Indifferent-uninterested in behavior change and only did target behaviors if family insisted. Our findings contribute to the field of behavioral medicine by suggesting the presence of specific subgroups of participants who respond differently to behavior change interventions and salient psychosocial characteristics that differentiate among these phenotypes. Future research should examine the utility of prospectively identifying psychosocial phenotypes for improving the tailoring of nutrition behavior change interventions.

RESUMO

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.

RESUMO

BACKGROUND: There are many potential health benefits to having nutrition education programs offered by expert outside sources in schools. However, little is known about why and how schools initiate, implement, and institutionalize them. Gaining this understanding may allow the impact and reach of nutrition and other health education programs in schools to be extended. METHODS: A total of 22 school community members from 21 purposefully selected New York City public elementary schools were interviewed using a semistructured interview protocol about their schools' experiences initiating, implementing, and institutionalizing nutrition education programs. Interviews were audiotaped and transcribed. Chronological narratives were written detailing each school's experience and passages highlighting key aspects of each school's experience were identified. These passages (N = 266) were sorted into domains and themes which were regrouped, resorted, and adjusted until all researchers agreed the domains and themes represented the collective experiences of the schools. RESULTS: The interviews elicited 4 broad domains of action: building motivation, choosing programs, developing capacity, and legitimizing nutrition education. Within each domain, themes reflecting specific actions and thoughts emerged. CONCLUSIONS: The identified domains of action and their themes highlight specific, practical actions that school health advocates can use to initiate, implement, and institutionalize nutrition education programs in schools.

BACKGROUND: Researchers have established the benefits of school gardens on students' academic achievement, dietary outcomes, physical activity, and psychosocial skills, yet limited research has been conducted about how school gardens become institutionalized and sustained. OBJECTIVE: Our aim was to develop a tool that captures how gardens are effectively established, integrated, and sustained in schools. DESIGN: We conducted a sequential, exploratory, mixed-methods study. Participants were identified with the help of Grow To Learn, the organization coordinating the New York City school garden initiative, and recruited via e-mail. PARTICIPANTS/SETTING: A stratified, purposeful sample of 21 New York City elementary and middle schools participated in this study throughout the 2013/2014 school year. The sample was stratified in their garden budgets and purposeful in that each of the schools' gardens were determined to be well integrated and sustained. MAIN OUTCOME MEASURES: The processes and strategies used by school gardeners to establish well-integrated school gardens were assessed via data collected from surveys, interviews, observations, and concept mapping. STATISTICAL ANALYSES PERFORMED: Descriptive statistics as well as multidimensional scaling and hierarchical cluster analysis were used to examine the survey and concept mapping data. Qualitative data analysis consisted of thematic coding, pattern matching, explanation building and cross-case synthesis. RESULTS: Nineteen components within four domains of school garden integration were found through the mixed-methods concept mapping analysis. When the analyses of other data were combined, relationships between domains and components emerged. These data resulted in the development of the GREEN (Garden Resources, Education, and Environment Nexus) Tool. CONCLUSIONS: When schools with integrated and sustained gardens were studied, patterns emerged about how gardeners achieve institutionalization through different combinations of critical components. These patterns are best described by the GREEN Tool, the first framework to identify how to operationalize school gardening components and describe an evidence-based strategy of successful school garden integration.

RESUMO

We developed a theory-based dietary change curriculum for Hispanic breast cancer survivors with the goal of testing the effects of the intervention on change in dietary intake of fruits/vegetables and fat in a randomized, clinical trial. Social cognitive theory and the transtheoretical model were used as theoretical frameworks to structure curriculum components using the Nutrition Education DESIGN Procedure. Formative assessments were conducted to identify facilitators and barriers common to Hispanic women and test the degree of difficulty and appropriateness of program materials. Focus groups provided valuable insight and informed preimplementation modifications to the dietary program. The result was a systematically planned, evidence-based, culturally tailored dietary intervention for Hispanic breast cancer survivors, ¡Cocinar Para Su Salud! (Cook for Your Health!). The methodology described here may serve as a framework for the development of future dietary interventions among diverse and minority populations. Short- and long-term study results will be reported elsewhere.

RESUMO

OBJECTIVE: To estimate the long-term cost-effectiveness of an obesity prevention nutrition education curriculum (Food, Health, & Choices) as delivered to all New York City fifth-grade public school students over 1 year. METHODS: This study is a standard cost-effectiveness analysis from a societal perspective, with a 3% discount rate and a no-intervention comparator, as recommended by the US Panel on Cost-effectiveness in Health and Medicine. Costs of implementation, administration, and future obesity-related medical costs were included. Effectiveness was based on a cluster-randomized, controlled trial in 20 public schools during the 2012-2013 school year and linked to published estimates of childhood-to-adulthood body mass index trajectories using a decision analytic model. RESULTS: The Food, Health, & Choices intervention was estimated to cost $8,537,900 and result in 289 fewer males and 350 fewer females becoming obese (0.8% of New York City fifth-grade public school students), saving 1,599 quality-adjusted life-years (QALYs) and $8,098,600 in direct medical costs. Food, Health, & Choices is predicted to be cost-effective at $275/QALY (95% confidence interval, -$2,576/QALY to $2,084/QALY) with estimates up to $6,029/QALY in sensitivity analyses. CONCLUSIONS AND IMPLICATIONS: This cost-effectiveness model suggests that a nutrition education curriculum in public schools is effective and cost-effective in reducing childhood obesity, consistent with the authors' hypothesis and previous literature. Future research should assess the feasibility and sustainability of scale-up.
