RESUMO

Since launching health health-promoting settings approach to health by WHO, valuable progress has happened in implementing its holistic concepts in settings such as cities, schools, workplaces, hospitals and healthcare services. However, significant knowledge-intention-success gaps still exist in creating sustainable health-promoting changes in settings. The complexity of the task of bridging this gap has contributed to the call for a complexity-informed paradigm shift to health as well as settings, followed by increasing consultation of relevant complexity theories, frameworks and tools in health research. This paper provides a critical scoping review of the application of complex adaptive system (CAS) theory in settings-based health promotion research. We included 14 papers, mostly qualitative studies, reporting on planning or implementation of change initiatives, less on its evaluation. CAS theory application was often incomplete thereby reducing the potential benefit of using this lens to understand change management. We suggest some recommendations how to comprehensively apply the CAS theory in setting-based health research and to report on all CAS characteristics to enhance the understanding of settings as adaptive health-promoting settings.

RESUMO

BACKGROUND: Food and nutrition literacy is a key factor in shaping healthy dietary behaviors and may result in decreasing decrease the prevalence of overweight. Empirical research on food and nutrition literacy and its outcomes is limited, especially among children and adolescents. Thus, this study investigates the link between Food and Nutrition Literacy (FNLIT) with eating behaviors, academic performance, and overweight in 10-12 years old students in Tehran, Iran. METHODS: This study was performed through two phases: 1) Proposing a conceptual model of the relationship between FNLIT and its determinants and outcomes, based on the existing evidence and previous models, and 2) Testing the proposed FNLIT model through a cross-sectional study on 803 primary school students (419 boys and 384 girls, from 34 public and 10 private primary schools), aged 10-12 years using structural equation modeling. Demographic, socio-economic, and household food security characteristics were collected by interviewing the students and their mothers/caregivers using a questionnaire. FNLIT was measured by a self-administered, locally designed, and validated questionnaire. RESULTS: The fit indices suggested a reasonably adequate fit of the data to the hypothesized model (χ2/df = 2.03, p < 0.001, goodness of fit index (GFI) = 0.90, adjusted goodness of fit index (AGFI) = 0.88, comparative fit index (CFI) = 0.91, incremental fit index (IFI) = 0.91, root mean square error of approximation (RMSEA) = 0.04, standardized root mean residual (SRMR) = 0.06). SES was directly and positively related to FNLIT and its subscale in students. FNLIT score had a positive direct (non-mediated) relationship with healthy eating behavior and academic performance. This pattern was strongly reversed in unhealthy eating behavior. There was a full mediation relationship between FNLIT and overweight/obesity via healthy eating behaviors. SES predicted academic performance partially through the mediating effect of Food Label Literacy (FLL). The results indicated that despite the direct relationship between SES and academic performance, an indirect but negative relationship existed with food insecurity. The finding also revealed the fully mediating role of Food Choice Literacy (FCL) in the relationship between demographic factors and healthy eating behaviors. Our study also found that Interactive Food and Nutrition Literacy (IFNL) protected unhealthy eating behaviors, and FCL predicted healthy eating behaviors in children. CONCLUSION: Our study draws attention to FNLIT, especially the skills domain, including IFNL, FCL, and FLL, as the most important determinant of healthy eating behavior, academic performance, and weight status in school-age children reduces social inequalities in children's development. To ensure an adequate level of FNLIT, educators should assess and plan to enhance food literacy skills in children and adolescents.

RESUMO

Given the growing market for health-enhancing or functional foods in Iran, the consumption rate is low. Identifying and understanding the causes is key for future decisions and interventions in the market. So, the present study was designed to provide this knowledge in Iran. The study was conducted in Tehran, the capital of Iran, between May and September 2014. In total, 105 people participated in this qualitative research, including 40 production/supply/health authority stakeholders and 65 consumer stakeholders (44 housewives and 21 employed women). The sampling strategy was the purposive method with maximum diversity, and snowball sampling was used to identify key stakeholders. The social marketing framework was used for analyzing the participants' views and experiences. To collect data, semi-structured focus group discussions and in-depth interviews were conducted. Data collection and content analysis were performed simultaneously, using MAXQDA® software. Categorization of the findings based on social marketing mix showed that the most important barriers to the consumption of functional dairy products were undesirable sensory and non-sensory characteristics, lack of physical and economic access to the product, the existence of product competitors in the market and inappropriate promotion strategies. Furthermore, personal barriers identified as a new dimension and included lack of knowledge about the product and its benefits, a negative attitude toward the product and personal taste and preference. Understanding these barriers might contribute to design and implement effective and appropriate interventions to increase the consumption of these products among consumers.

RESUMO

This study used a locally designed and validated questionnaire to describe the distribution of food and nutrition literacy (FNLIT) in a cross-sectional sample of 803 students aged 10-12 years from elementary schools in Tehran city, Iran. Logistic regression was used to assess the extent to which various independent covariates were associated with low FNLIT. The data were used to identify significant differences using a range of social and cultural variables relevant to the context of school students in Iran. The results of the study showed that although the total FNLIT level was good, this headline finding masked important differences in the sub-domains. More than half of the children (69%) had high levels of FNLIT in the cognitive domain, but in the skills domain, very few (3%) scored highly. The study also identified some associations between the total FNLIT and its subscales and sociodemographic variables including gender, parent's education and age, birth order. These results highlighted groups within the school population who were at higher risk of having lower FNLIT levels. They also indicate that girls feel more able to exert choice and control over food and nutrition decisions than boys are but may be less able to do so in practice. Overall, these results are a general reminder to schools of the different learning needs of children from different family backgrounds. The article highlights the need for continuous improvement in the health education curriculum of schools in Iran, particularly highlighting the importance of giving greater attention to the development of practical food and nutrition skills alongside more traditional food and nutrition knowledge. Additional studies (with long-term follow-up) are needed to more fully assess and understand the predictors of FNLIT.

RESUMO

BACKGROUND: The underlying mechanism of the effect of FTO genotype on body mass index (BMI) and body composition is unknown. The objective of the study was to investigate the association of FTO gene polymorphisms with anthropometric indices in adolescent boys after adjustments for dietary intake and physical activity. METHODS: In this school-based study, we enrolled 123 male adolescents without extra weight and 110 male adolescents with body mass index (BMI) higher than + 1 Z-score. The DNA samples were genotyped for the FTO gene polymorphisms by DNA Sequencing. BMI and body composition were assessed using bioelectrical impedance analyzer scale. Association of the FTO polymorphisms with Weight, height, BMI, body fat percent and skeletal muscle percent were investigated. Data on potential confounders (calorie intake and physical activity) were collected through the use of pre-tested questionnaires. RESULTS: Adolescents with higher BMI and body fat percent and lower skeletal muscle percent were more likely to have a newly found haplotype of rs9930506, rs9930501 & rs9932754 (GGT) in the first intron of the FTO with complete linkage disequilibrium (LD) compared with those with the lower BMI (6.15;2.28-16.63), body fat percent (9.54;0.92-47.44) and higher skeletal muscle percent (9.26;1.85-46.38). This association was not changed after controlling for age. Additional adjustments for calorie intake and physical activity did not alter the association. CONCLUSIONS: A haplotype in the first intron of the FTO gene had a strong association with obesity indices in adolescent boys after adjustments for calorie intake and physical activity. It's suggested that the FTO genotype exert its effects on adolescents' anthropometric indices as haplotype and through mechanisms other than changes in calorie intake and expenditure. TRIAL REGISTRATION: This paper reports the first phase of a comprehensive interventional study (Interactions of Genetics, lifestyle and anthropometrics study or IGLA study) and is retrospectively registered in the Iranian Registry of Clinical Trials as IRCT2016020925699N2. Date registered: April 24, 2016. ( http://www.irct.ir/searchresult.php?id=25699&number=2 ).

RESUMO

INTRODUCTION: Health promoting workplace frameworks provide a holistic view on determinants of workplace health and the link between individuals, work and environment, however, the operationalization of these frameworks has not been very clear. This study provides a typology of the different understandings, frameworks/tools used in the workplace health promotion practice or research worldwide. It discusses the degree of their conformity with Ottawa Charter's spirit and the key actions expected to be implemented in health promoting settings such as workplaces. METHOD: A comprehensive online search was conducted utilizing relevant key words. The search also included official websites of related international, regional, and national organizations. After exclusion, 27 texts were analysed utilizing conventional content analyses. RESULTS: The results of the analysis were categorized as dimensions (level or main structure) of a healthy or health promoting workplaces and subcategorized characteristics/criteria of healthy/health promoting workplace. DISCUSSION AND CONCLUSION: Our analysis shows diversity and ambiguity in the workplace health literature regarding domains and characteristics of a healthy/health promoting workplace. This may have roots in lack of a common understanding of the concepts or different social and work environment context. Development of global or national health promoting workplace standards in a participatory process might be considered as a potential solution.

RESUMO

The Iranian Health Promoting Schools (IHPS) program was first piloted and then formally established in Iran in 2011 as a framework to promote healthy environment and behaviors such as proper dietary practice among adolescents. This study examined the role of IHPS in improving the school food environment and snacking behaviors among adolescents. In this cross-sectional study, 1320 eighth grade students from 40 middle schools with IHPS and non-IHPS program were selected using a proportional stratified random sampling method. A modified 55-item qualitative Food Frequency Questionnaire was used to assess the frequency of consumption of healthy and unhealthy snacks in the studied adolescents. Mixed effect negative binomial regression models were used to analyze the data. The association was also adjusted for individual variables, including gender, socio-economic status, pocket money, family structure and nutritional knowledge level. No significant difference was observed between the average of healthy and unhealthy snack items in IHPS and non-IHPS schools (p > 0.05). On the basis of adjusted analysis, being from/in IHPS was not associated with weekly frequency consumption of unhealthy [prevalence rate ratio (PRR) = 0.99; 95% CI: 0.85-1.16] and healthy (PRR = 1.08; 95% CI: 0.96-1.2) snacks among the adolescents. There was no difference regarding school food environment and snacking behaviors in IHPS and non-IHPS schools. This might indicate that there has been a weakness in institutionalizing the comprehensive concepts of the HPS approach in the studied schools. Addressing the proper understanding of HPS approach and the need for development of HPS through matching and adaptability with health promotion actions to reach defined standards, is necessary.

RESUMO

Community-based health promotion requires effective participation and partnership of diverse and numerous stakeholders from community as well as external professional organizations. Although effective partnership of stakeholders is often the key for success of health promotion practice and research, but this has proved to be a complex and challenging task. This study is an exploratory study to identify professional stakeholder's perspectives and experiences toward the partner's engagement challenges in community-based participatory research conducted in Population Research Centers in Iran. A qualitative study design with in-depth semi-structured interviews as data collection method was chosen. Using purposeful sampling technique, policy-makers and managers (mainly academics) involved in community-based participatory research in these centers were invited to be interviewed. Data were collected to the point where no new information was forthcoming. All interviews were taped and transcribed. To provide answers for research questions, qualitative content analysis was employed to extract emerging main themes from numerous cods. Findings were categorized in three main themes as Partnership's relationship and trust issues, Partnership's individual issues and Partnership's system issues. Although community-based participatory research in Iran benefits from more than a decade history and some physical infrastructures, but it seems that public health experts and researchers and other partner organizations are lagging behind in terms of capacities and competencies required to effectively utilize the available structure and opportunities. Hence, capacity development, both among professional partners and community may be the main way forward to tackling the future challenges for strengthening community actions but should include both levels of individuals and systems.

RESUMO

Introduction: Suicide is a major issue of concern for public health. It is estimated that suicide accounts for 700,000 deaths every year. A personal history of one or more suicide attempts is the most important determinant of suicide among the general population. This study aimed to assess the major risk factors associated with suicidal behaviors among Iranian employees in a medical setting. Methods: In this study, 3,913 employees of Tehran University of Medical Sciences who participated in the employees' cohort study conducted by the university were recruited. Suicidal behaviors (SBs) and their associated risk factors were evaluated using the World Mental Health Composite International Diagnostic Interview (CIDI) Version 3.0. Univariate and multivariate logistic regressions were performed to identify the determinants of SBs among the participants, and crude and adjusted odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) were calculated. Results: Overall, 49.6% of respondents (n = 1,939) reported that they were tired of life and thinking about death. The lifetime prevalence rate of suicidal ideation (SI) was 8.1% (n = 317), that of suicide planning (SP) was 7.3% (n = 287), and that of suicide attempts (SA) was 3.1% (n = 122). Being female (OR: 1.87, CI: 1.64-2.12), being divorced (OR: 3.13, CI: 1.88-5.22), having a low level of education (OR: 1.57, CI: 1.15-2.14), and working in clinical and medical services (OR: 1.25, CI: 1.09-1.43) were associated with being tired of life and thinking about death. These factors were also associated with SI, SP, and SA. Discussion: These findings highlight the need to prioritize mental health for suicide prevention, especially for high-risk groups, in workplace mental health promotion programs and policies.

RESUMO

BACKGROUND: This study aimed to develop a conceptual framework to better understand food and nutrition literacy and its dimensions and components among Iranian children. METHODS: The study included three sub-studies. First, two qualitative studies were conducted to explore experts' and students' perspectives and experiences regarding the topic. A comprehensive qualitative literature review was then conducted to identify food/nutrition literacy definitions and its components in the relevant literature. The data of the above three sub-studies were compiled as text data and were analyzed utilizing MAXQDA2010 software. RESULTS: Two main domains, including cognitive and skill domains, emerged from the data analysis. The cognitive domain consisted of food- and nutrition-related knowledge included four subcategories "nutrition knowledge", "lifestyle knowledge", "food safety knowledge", and "knowledge of food and its preparation") as well as "food and nutrition understanding". The skill domain consisted of three dimensions: "functional", "interactive", and "critical" food and nutrition literacy. CONCLUSIONS: The developed framework highlights the importance of integrated application of all dimensions of food and nutrition literacy among this population group. It can assist policymakers and curriculum developers in assessing education curricula and developing effective strategies for teaching and learning to increase students' food and nutrition literacy.

RESUMO

Introduction: This systematic review aimed to evaluate community-based participatory (CBP) interventions to improve food security and/or its dimensions to highlight the scope and characteristics of interventions and extract the characteristics of effective interventions. Methods: The electronic databases, including PubMed/MEDLINE, SCOPUS, EMBASE, Web of Science, and Google Scholar, were searched from 1980 to 30 August 2022 for relevant studies. We included randomized controlled trials (RCTs), cluster randomized controlled trials (cRCTs), controlled before and after studies (CBAs), non-randomized controlled trials (nRCT), and interrupted time series (ITS) studies to identify the community-based participatory interventions. The indicators of food and nutrition security into four dimensions, as well as food insecurity measured as score and/or prevalence of food insecurity based on validated perception-based measures were considered outcome. Two reviewers independently evaluated the studies for eligibility, extracted data, and evaluated the risk of bias in the included studies using the Effective Public Health Practice Project (EPHPP). The quality of included reports was categorized as strong (when there were no weak ratings), moderate (when one factor was rated as weak), or weak (when two or more factors were rated as weak). A descriptive analysis of the findings was performed. Results: A total of twelve studies were included. The quality of all eligible studies (n = 12) was rated as moderate/weak. Most CBP interventions were guided by formative research (n = 9, 75%). Two main groups for utilized strategies were identified: agricultural and nutrition strategies. Agricultural strategies included agricultural education, preparing and improving soil and seeds, promoting and supporting gardening/harvesting utilizing traditional skills based on the local culture, and agroecological practices. Nutrition strategies included store and shopping programs, farmers' markets, fresh fruit and vegetable programs, nutrition education programs for mothers, and food vouchers. The main outcomes improved in the CBP interventions were food security (n = 2) and its dimensions, including availability (n = 3), access (n = 5), and utilization (n = 2). All agroecological practices achieved statistically significant outcomes in the intended food security target(s). However, nutritional interventions were not effective for some access components such as mean adequacy ratio, fruit and vegetable intake, and nutrition environment of the stores. No studies evaluated stability outcome components of food security. Discussion: CBP interventions guided by formative research data and agroecological practices were promising strategies to improve food security and its dimensions. Insufficient data on the stability components of food security and weak design studies were the considerable gaps in the research evidence reviewed. More research employing randomized experimental designs with adequate sample size and high retention rates is required.

RESUMO

To mark the 25th anniversary of the Ottawa Charter, this paper will discuss what remains to be achieved in strengthening community actions as an integral part of health promotion practice. To do this, the paper discusses four key elements for the future of health promotion programmes: (1) engage communities to share priorities; (2) build community capacity; (3) mechanisms for flexible and transparent funding; and (4) being creative in order to expand or replicate successful local initiatives. The paper uses a number of international case study examples of how these key elements can be achieved in health promotion programmes. A major challenge for the future is how health promotion agencies can develop and maintain the trust of communities, especially socially marginalized communities in society. The paper concludes by identifying a number of short and longer term challenges to achieve these goals and offers a way forward for a brighter future direction of health promotion practice.

RESUMO

OBJECTIVE: This study aims to assess the relationship between Food and Nutrition Literacy (FNLIT) and dietary diversity score (DDS); FNLIT and nutrient adequacy (NAR%, MAR%) in school-age children in Iran. RESULTS: This cross-sectional study was undertaken on 803 primary school students in Tehran, Iran. Socio-economic, as well as three 24-h dietary recalls were collected through interviewing students and their mothers/caregivers. FNLIT was measured by a self-administered locally designed and validated questionnaire. Low level of FFNL was significantly associated with higher odds of low DDS (OR = 2.19, 95% CI 1.32-3.62), the first tertile of fruit diversity score (OR = 3.88, 95% CI 2.14-6.99), and the first tertile of dairy diversity score (OR = 9.60, 95% CI 2.07-44.58). Low level of IFNL was significantly associated with probability of lower meat diversity score (OR = 1.73, 95% CI 1.07-2.81). Low level of FLL was also significantly associated with probability of lower DDS (OR = 1.81, 95% CI 1.11-2.94), dairy diversity score (OR = 2.01, 95% CI 1.02-3.98), and meat diversity score (OR = 2.14, 95% CI 1.32-3.45).Low FNLIT and its subscales were associated with higher odds of low level of NAR of protein, calcium, vitamin B3, B6, B9, as well as the probability of lower level of MAR.

RESUMO

Organisations can have a significant impact (positive or negative) on society through their actions and decisions. Given this reality, it is important that they are held responsible and accountable for the consequences of their actions. This concept is often referred to as 'social responsibility'. However, 'social responsibility', as currently conceived in the literature, neglects a specific focus on health as a social goal. Additionally, there are no practical tools to capture this concept in a holistic way to facilitate implementation and monitoring of organisational improvement. This paper reports on the process of developing a more holistic conceptual framework and tool for assessing organisational social responsibility and accountability for health (OSRAH). We conducted a review of the published and grey literature and engaged in expert consultation and focus group discussions. The initial OSRAH framework and the self-assessment tool were finalised for implementation and used by 95 organisations at a national event in Iran in February 2017. The results of the assessment data collected at the event showed organisations scored lowest in the domain of community health and highest in the domain of employee health. The OSRAH framework and assessment tool represents a new understanding of health and its determinants in organisations outside the health sector. It integrates health within the existing Corporate Social Responsibility (CSR) culture of organisations. The process of creating the tool and implementing it at the national festival of OSRAH in Iran created momentum for intersectoral action. This experience can inspire researchers and practitioners in other countries, especially in developing countries, to develop their own local definition and practical assessment framework for responsibility and accountability.

RESUMO

The role of FTO genotype in the effect of FTO gene expression level on change in body mass index and body composition has not been studied. This study aimed to investigate the role of FTO genotype in the association between change in the expression level of the FTO gene with changes in anthropometric measurements in obese and overweight adolescent boys. Eighty-four boys aged 12 to 16 years participated in this longitudinal study. A bioimpedance analyzer (BIA) was used to estimate percentage of body fat (%body fat) and percentage of skeletal muscle (%skeletal muscle). The FTO gene expression level in peripheral blood mononuclear cells (PBMCs) was assessed using quantitative Real Time PCR (qPCR). The DNA samples were genotyped for the FTO gene polymorphisms by DNA sequencing. All measurements were performed at baseline and after intervention. A significant association was observed between the level of gene expression and %skeletal muscle. The gene expression fold change was significantly associated with change in %skeletal muscle in AA or AG genotype carriers (ß = 0.34, p = .02). No significant association was detected between the change in FTO gene expression with change in anthropometric indices in GG genotype carriers. In conclusion, the association between FTO gene expression and body composition can be influenced by FTO genotype. Future studies are required to assess the interactions between FTO genotype, FTO gene expression in different tissues, and body composition.
