The overreaching objective of the current study is to investigate the association of quality of life with Afghan households' food insecurity. The data was collected immediately after the Taliban took control of a large part of Afghanistan. About a total of 555 households' heads participated in a face-to-face interview, using the HFIAS and WHOQOL-100 questionnaires along with some questions related to their socioeconomic characteristics at two different times, before and after the Taliban's takeover.

This study sought to examine the association between FNL and its components with diet quality and nutrient density among Iranian senior highschool students.
Methods: In this cross-sectional study, 755 senior high school students were recruited from high schools in Tehran, Iran.
Background And Aim: Community-based initiatives are important for obesity prevention. This study aimed to evaluate the activities of municipal obesity prevention clubs (OBCs) in Tehran, Iran, using a participatory approach.
Methods: The evaluation team was formed, and the members identified the OBC's strengths, and challenges and provided suggestions for change through a participatory workshop, observation, focus group discussions, reviewing relevant documents ( = 97), and 35 interviews with involved stakeholders.
Background: Community Readiness Intervention for Tackling Childhood Obesity (CRITCO) is a theory-based intervention being developed to improve the readiness of an Iranian urban population to engage in childhood obesity prevention programs. This study aimed to explore changes in readiness of intervention and control local communities from diverse socio-economic areas of Tehran.
Methods: This study was a seven-month quasi-experimental intervention implemented in four intervention communities and compared with four controls.
Objectives: It is critical to assess community readiness (CR) when implementing childhood obesity prevention programs to ensure their eventual success and sustainability. Multiple tools have been developed based on various conceptions of readiness. One of the most widely used and flexible tools is based on the community readiness model (CRM).

Improving food and nutritional literacy in children is a necessary solution to eliminate nutritional disorders in this age group. The purpose of this study was to design, implement and evaluate an intervention to improve food and nutrition literacy in children aged 10-12 years old based on an intervention mapping (IM) approach.

Methods: The study included three sub-studies. First, two qualitative studies were conducted to explore experts' and students' perspectives and experiences regarding the topic.
Background: Depression is one of the prevalent mental disorders that is common in older ages. Evidence suggests that dietary intake status may potentially be associated with depression. However, this association has not been well studied in older adults, and the nature of the association remains unclear.

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.
View Article and Find Full Text PDFThere is widespread agreement among experts that a fundamental reorientation of global, regional, national and local food systems is needed to achieve the UN Sustainable Development Goals Agenda and address the linked challenges of undernutrition, obesity and climate change described as the Global Syndemic. Recognising the urgency of this imperative, a wide range of global stakeholders - governments, civil society, academia, agri-food industry, business leaders and donors - convened at the September 2021 UN Food Systems Summit to coordinate numerous statements, commitments and declarations for action to transform food systems. As the dust settles, how will they be pieced together, how will governments and food corporations be held to account and by whom? New data, analytical methods and global coalitions have created an opportunity and a need for those working in food systems monitoring to scale up and connect their efforts in order to inform and strengthen accountability actions for food systems.
