Abstract
BACKGROUND Dietary practices are one of the most common modifiable risk factors for cancers. Foods rich in dietary fibers are considered protective, meanwhile fast & junk foods are risk for common cancers. Adolescence period is marked by habit formation and is thus suited for delivering behavioral intervention. Schools offer an optimal setting for planning and executing these interventions to a large number of adolescents. OBJECTIVE To assess the effectiveness of a teacher-delivered cancer-prevention education in changing dietary behaviors of school going adolescents. METHODS A cluster randomized trial was conducted in government secondary and senior secondary schools with schools as clusters. A minimum required sample of 1032 students was estimated from 16 schools with 1:1 allocation in intervention and non-intervention groups. Dietary behaviors were recorded as dichotomous variable. The determinants were recorded as per theory of planned behavior framework using Likert-scale. Two teachers from each intervention school were trained to deliver cancer prevention education with focus on role of dietary behavior. Pre-post training assessment of teachers' knowledge towards common cancers was done using a self-administered questionnaire. Gender adjusted difference-in-difference analysis was done to assess intervention effect on both healthy and unhealthy behaviors. RESULTS In selected schools all students from classes 8 to 10 were approached and a total of 1224 students were enrolled, of whom 1096 completed the study. The study recorded significant improvement in scores of students from intervention group compared to non-intervention group for their attitude, subjective norms, perceived behavioral control and intention towards consuming healthy and avoiding unhealthy foods. The intervention was effective in significantly improving the proportion of students limiting fried/fast/packed food & sugar sweetened beverages (OR:1.51, 95%CI:1.08,2.12,p:0.017), and consuming fruits & vegetables daily (OR:1.55, 95%CI:1.08,2.22, p:0.017) while adjusting effect of gender. CONCLUSION Classroom-based cancer prevention education delivered through teachers during regular working hours is effective in improving dietary behaviors and its determinants among adolescent students. Thus, we recommend integrating a section focusing on the role of diet in cancer prevention and other lifestyle diseases in the existing school curriculum. TRIAL REGISTRATION The trial was registered under Clinical Trial Registry-India with registration number CTRI/2018/12/016586, dated-10/12/2018.

Abstract
OBJECTIVES Older adults are a vulnerable group that is at risk of poor nutritional status, which can lead to disease and increase their healthcare costs. Our study aimed to investigate the impact of a self-efficacy intervention on the nutritional status of older adults. METHODS A controlled before and after study was conducted on 110 older adults in the Mashhad, Iran, from 2020 to 2022. Participants were randomly allocated to the intervention (n = 55) and control groups (n = 55). Participants in the intervention group received educational training that was based on the self-efficacy theory. The control group received the routine care. Data collection tools included demographic information questionnaire, Mini Nutritional Assessment Questionnaire, and standard self-efficacy questionnaire. The questionnaires were completed at baseline (before intervention), instantly after the intervention, and at 3-months follow-up by participants in both groups. Data were analyzed using SPSS version 25 and the significance level was considered less than 0.05. RESULTS The Mean of nutritional status in the intervention group, at the baseline, immediately after intervention and 3 months of follow-up were 25.1 ± 2.3, 28.3 ± 5.2 and 27.6 ± 6., respectively. This increase was significant (p < 0.001). Our findings revealed that self-efficacy among participants in the intervention group significantly changed (P < 0.001) across time from baseline through follow-up. There was no significant difference in the mean of self-efficacy and nutritional status in the control group during the study period (P > 0.05). CONCLUSION This current study provided a basis to examine in the effectiveness of such intervention using a properly powered randomized controlled study. Therefore, it can be concluded that self-efficacy interventions are a promising approach to improving the nutritional behaviors of the older adults. TRIAL REGISTRATION IRCT20160619028529N9.

Abstract
The objective of this narrative review was to summarize existing literature on the effectiveness of school-based interventions, implemented in Europe, under the aim of promoting healthy lifestyle behaviors in children (6-10 years old). A search of PubMed, Scopus, EFSA and Google Scholar databases was performed for studies published from January 2016 to June 2022. Specific search terms and exclusion criteria were used. Based on the results, diet and physical activity interventions had favorable effects on a series of health outcomes, including anthropometric parameters, biomarkers, eating behavior and self-efficacy. Diet-only interventions had a positive impact specifically on eating habits, mostly on water consumption. Most successful interventions lasted for 1 school year, and they were characterized by parental involvement and teachers' training.

Abstract
OBJECTIVE The relative contribution of health promotion models (HPM) to improve health-related behaviours in intervention programmes is still limited. Here, we tested whether Pender's HPM operationalised in the educational intervention was effective to modify nutrition and physical activity (PA) behaviours among Iranian women. DESIGN A randomised controlled field trial evaluating the efficacy of an educational intervention based on Pender's HPM to improve PA and nutrition behaviours from August 2016 to October 2016. R version 3.0.2 and SPSS version 16 were used to conduct multiple statistical analyses. SETTING Ten public healthcare centres in Bojnourd, Iran were randomly divided into intervention and control groups. The experimental group received the full intervention programme, which included nine 4-h training sessions and consulting support via phone contact and social media group. The control group did not receive any intervention. PARTICIPANTS Women aged 4-6 years (n 202) were randomised to intervention (n 102) and control conditions (n 100) and completed baseline and 3-month follow-up. RESULTS In the experimental group, the intervention programme had a significant effect (P < 0·05) on all construct of Pender's HPM and behaviour outcome, and the estimates for prior behaviours, self-efficacy, interpersonal influences, feeling, perceived benefits and barriers, commitment and behaviour outcomes in the intervention group were 0·72 (95 % CI 0·31, 0·98), 0·54 (95 % CI 0·27, 0·71), 0·74 (95 % CI 0·27, 0·91), 0·52 (95 % CI 0·19, 0·75), 0·62 (95 % CI 0·22, 0·91), 0·63 (95 % CI 0·30, 0·86) and 0·56 (95 % CI 0·37, 0·85), respectively. CONCLUSIONS Educational intervention based on Pender's HPM was feasible and highly acceptable to modify PA and nutrition behaviours in the women population.

Abstract
Nutrition interventions developed using behaviour theory may be more effective than those without theoretical underpinnings. This study aimed to document the number of theory-based healthy eating interventions, the involvement of dietitians/nutritionists and the behaviour theories employed from 2000 to 2020. We conducted a review of publications related to healthy eating interventions that used behaviour change theories. Interventional studies published in English between 2000 and 2020 were retrieved from searching Medline, Cinahl, Embase, Psycinfo and Cochrane Central. Citation, country of origin, presence or absence of dietitian/nutritionist authors, participants, dietary behaviours, outcomes, theories and any behaviour change techniques (BCTs) stated were extracted. The publication trends on a yearly basis were recorded. A total of 266 articles were included. The number of theory-based interventions increased over the two decades. The number of studies conducted by dietitians/nutritionists increased, but since 2012, increases have been driven by other researchers. Social cognitive theory was the most used behaviour theory. Dietitians/nutritionists contributed to growth in publication of theory-based healthy eating interventions, but the proportion of researchers from other professions engaged in this field increased markedly. The reasons for this growth in publications from other professions is unknown but conjectured to result from greater prominence of dietary behaviours within the context of an obesity epidemic.

Abstract
School-based interventions are promising for targeting a change in obesity-related behaviours in children. However, the efficacy of school-based interventions to prevent obesity remains unclear. This review examined the effectiveness of school-based interventions at changing obesity-related behaviours (increased physical activity, decreased sedentary behaviour and improved nutrition behaviour) and/or a change in BMI/BMI z-score. Following PRISMA guidelines, seven databases were systematically searched from 1 January 2009 to 31 December 2020. Two review authors independently screened studies for eligibility, completed data extraction and assessed the risk of bias of each of the included studies. Forty-eight studies met the inclusion criteria and were included in a narrative synthesis. Thirty-eight studies were eligible for inclusion in a meta-analysis. The findings demonstrate that interventions in children when compared to controls resulted in a small positive treatment effect in the control group (2.14; 95% CI = 0.77, 3.50). There was no significant effect on sedentary behaviour, energy intake and fruit and vegetable intake. Significant reductions were found between groups in BMI kg/m2 (-0.39; 95% CI = -0.47, -0.30) and BMI z-score (-0.05; 95% CI = -0.08, -0.02) in favour of the intervention. The findings have important implications for future intervention research in terms of the effectiveness of intervention components and characteristics.

Abstract
Malnutrition—both undernutrition and overnutrition—is a public health concern worldwide and particularly in low‐ and middle‐income countries (LMICs). The education sector has high potential to improve immediate nutrition outcomes by providing food in schools and to have more long‐term impact through education. We developed a conceptual framework to show how the education sector can be leveraged for nutrition. We reviewed the literature to identify existing frameworks outlining how nutrition programs can be delivered by and through the education sector and used these to build a comprehensive framework. We first organized nutrition programs in the education sector into (1) school food, meals, and food environment; (2) nutrition and health education; (3) physical activity and education; (4) school health services; and (5) water, sanitation, and hygiene (WASH) sector. We then discuss how each one can be successfully implemented. We found high potential in improving nutrition standards and quality of school foods, meals and food environment, especially through collaboration with the agriculture sector. There is a need for well‐integrated, culturally appropriate nutrition and health education into the existing school curriculum. This must be supported by a skilled workforce—including nutrition and public health professionals and school staff. Parental and community engagement is cornerstone for program sustainability and success. Current monitoring and evaluation of nutrition programming in schools is weak, and effectiveness, including cost‐effectiveness, of interventions is not yet adequately quantified. Finally, we note that opportunities for leveraging the education sector in the fight against rising overweight and obesity rates are under‐researched and likely underutilized in LMICs.

Abstract
Data on how the complex cognitive processes, personal, and social factors influence health promoting behaviors of women are very limited and the results have been inconsistent. Here, we examine how prior behaviors, behavior-specific cognition (perceived benefits/barriers, self efficacy, and activity-related affect), situational and interpersonal factors (social support, modeling, and norms) associated with the level of dietary behaviors in Iranian women. A cross sectional survey of 356 women aged 18-60 years from health care centers in Iran was undertaken from October 2015 to September 2016. Multiple analytical models and Pender's health promotion model (HPM) were implemented to examine the effectiveness of HPM and its potential constructs on PA behaviors. The instruments used were designed using Pender's HPM as a basis. The path model fitted data and accounted for 51% of the variance in dietary behaviors; and prior behavior, perceived self-efficacy, interpersonal influences, and commitment to plan were significantly associated with dietary behavior. We found that constructs from the HPM are empirically improved dietary behavior among the women population. This result provides a suitable source for designing strategies of a nutrition education intervention for improving the frequency and nutrient intake of breakfast consumption among female students.

Abstract
AIMS This review aimed to evaluate the effectiveness of healthy eating interventions among normal-weight children. DESIGN A systematic review of randomized controlled trials. DATA SOURCES Seven databases were searched from the inception of each database until September 2019. REVIEW METHODS A systematic review of quantitative studies was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the PRISMA extension for reporting a synthesis without a meta-analysis. RESULTS Fifteen studies were included in this review. A meta-analysis could not be conducted because of the observed heterogeneity across studies. There were mixed effects of the included interventions on healthy eating habits, ranging from effective to not effective. Only a few studies found behavioural determinants effective in enhancing healthy eating. CONCLUSION Because of the observed heterogeneity and varied outcome variables, a meta-analysis could not be conducted, and the overall effectiveness of the included interventions could not be verified. Interventions that were theory based, parent focused, and delivered through the multimodal interactive approach were found to be effective in enhancing healthy eating habits among children. More studies involving peers that are institution based need to be conducted.

Abstract
Most children and adolescents do not meet dietary recommendations that may result in poor diets contributing to obesity. This systematic literature review was conducted to examine associations between helping with meal preparation at home and dietary quality, intake of specific foods, and/or dietary-related perceptions among youth. A search of databases using key terms was conducted for studies meeting criteria. This literature review included 15 studies using a cross-sectional descriptive design, with two studies also including a longitudinal design. Data were self-reported (or parent-reported) using various surveys and/or interviews. Study findings supported positive associations between youth involvement in home meal preparation and improvement in overall dietary quality, increased consumption of fruits and vegetables, greater preference for vegetables, and higher self-efficacy for cooking and choosing healthy foods. Further research is needed to develop efficacious meal preparation interventions involving parents and their children to promote this mealtime behavior with many potential health benefits.
