Economic Sanctions Affecting Household Food and Nutrition Security and Policies to Cope With Them: A Systematic Review.

BACKGROUND: This review was conducted to identify the impact of economic sanctions on household food and nutrition security and policies to cope with them in countries exposed to sanctions. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines 2020 were used to identify, select, appraise, and synthesize studies. Electronic databases in addition to Persian ones have been systematically searched for all related documents published until March 2022. Exclusion criteria were: lack of data related to food insecurity in countries subject to sanction and very low quality of the article. The quality of included studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal checklists. The results were presented as qualitative and quantitative syntheses. RESULTS: Of 1428 identified studies, 36 publications remained in the review, which belong to Iran (n=8), Cuba (n=8), Russia (n=7), Iraq (n=7), and Haiti (n=6), respectively. Declining gross domestic product (GDP), devaluation of the national currency, and the quality of food, increase in inflation, unemployment, and consumer prices, infant and under 5 years mortality, energy, and protein deficiency, and the poverty rate were reported as sanction consequences. The most important strategies to improve food security were the humanitarian assistance provided by the international community (Haiti), equity and priority for vulnerable groups mainly by expanding the healthcare system (Cuba), adopting a food ration system in the oil-for-food program, and fixing the price of food baskets (Iraq), import substitution and self-sufficiency (Russia), support domestic production, direct and indirect support and compensation packages for vulnerable households (the approach of resistance economy in Iran). CONCLUSION: Due to the heterogeneity of studies, meta-analysis was not possible. Since inadequate physical and economic food access caused by sanctions affects especially disadvantaged and vulnerable groups, planning to improve food security and providing support packages for these groups seems necessary.

Structural equation modeling analysis of Iranian womens food consumption: influence of socio-demographic characteristics and the information, motivation, and behavioral skills model / Análise de modelagem de equações estruturais do consumo alimentar de mulheres iranianas: influência das características sociodemográficas e do modelo de Informação, motivação e habilidades comportamentais

ABSTRACT Objective This study aimed at examining whether food consumption varies in accordance with socio-demographic and behavioral factors in the conceptual model, analyzing adult women in Tehran, Iran, for that purpose. Methods This cross-sectional study was conducted with 247 women in childbearing age, who were selected through systematic cluster sampling from five regions in Tehran. Dietary assessment was done through a Food Frequency Questionnaire, and the anthropometric indices were measured. Data on socio-economic status and information-motivation-behavioral skills model were obtained through a questionnaire. Then, subjects were stratified according to the socio-economic status and model components. Statistical analysis was done using analysis of variance and structural equation modeling. Results Consumption of food groups among the participating women differed based on their living region, education, occupation, household expenditure, and model components (p<0.05). Intake of red and processed meat (p<0.05) was at the lowest level in illiterate or low educated women. Those with lower total expenditure had higher consumption of fats and oils (p<0.05). Women with higher perceived social support consumed more milk and dairy products (p<0.05), fats and oils (p<0.05), and less bread and cereals (p<0.05). Model components including information, attitude, social support, self-efficacy, and self-regulation were the most important factors negatively affecting the consumption of unhealthy foods (red and processed meat, fats and oils, sugar, and salty foods). Conclusion Considering the impact of model components on women's eating behaviors, the specific integration strategies delineated for each construct of the model can be utilized to design model-based interventions targeting the promotion of healthy nutritional behavior.

RESUMO Objetivo Este estudo buscou examinar se o consumo de alimentos varia de acordo com fatores sociodemográficos e comportamentais no modelo conceitual entre mulheres adultas em Teerã, Irã. Métodos Este estudo transversal foi conduzido em 247 mulheres em idade reprodutiva, selecionadas por amostragem sistemática por conglomerados de cinco regiões de Teerã. A avaliação da dieta foi realizada por meio de um questionário de frequência alimentar, e os índices antropométricos foram medidos. Os dados sobre o status socioeconômico e o modelo de habilidades de informação-motivação-comportamento foram obtidos através de um questionário. Em seguida, os sujeitos foram estratificados conforme o status socioeconômico e os componentes do modelo. A análise estatística utilizou análise de variância e modelagem de equações estruturais. Resultados O consumo de grupos de alimentos entre as mulheres participantes diferiu de acordo com a região onde vivem, educação, ocupação, gasto familiar e componentes do modelo (p<0,05). A ingestão de carne vermelha e processada (p<0,05) foi mais baixa entre mulheres analfabetas ou com baixa escolaridade. Aquelas com menor gasto total apresentaram maior consumo de gorduras e óleos (p<0,05). Mulheres com maior apoio social percebido consumiram mais leite e derivados (p<0,05), gorduras e óleos (p<0,05) e menos pão e cereais (p<0,05). Os componentes do modelo, incluindo informação, atitude, apoio social, autoeficácia e autorregulação, foram os fatores mais importantes que afetaram negativamente o consumo de alimentos não saudáveis (carne vermelha e processada, gorduras e óleos, açúcar e alimentos salgados). Conclusão Considerando o impacto dos componentes do modelo nos comportamentos alimentares das mulheres, as estratégias de integração específicas delineadas para cada construto do modelo podem ser utilizadas para projetar intervenções baseadas em modelos visando promover um comportamento nutricional saudável.

Socioeconomic determinants of excess weight and central obesity among Iranian women: Application of information, motivation, and behavioral skills model.

INTRODUCTION: In developing countries, there is an increased risk of incidence of noncommunicable diseases due to general and abdominal obesity. Therefore, this study aimed to assess socioeconomic determinants of excess weight and central obesity among women in Tehran city based on information motivation behavioral skills model (IMB). MATERIALS AND METHODS: A cross-sectional study was conducted among 260 women aged between 20 and 49 years old using cluster sampling. A skilled interviewer completed socioeconomic status (SES), food insecurity, and IMB questionnaires. Analysis of variance, Chi-square tests, and regression model were used for statistical analysis. The multiple logistic regression analysis was used to identify independent predictors of the excess weight and central obesity using SPSS 21. RESULTS: The mean and standard deviation of participants' age was 34.7 (±7.59) years old. The prevalence of overweight and obesity in adult women was estimated 35% and 21.2%, respectively. The prevalence of abdominal obesity was 34.6%. Independent predictors of overweight/obesity in women were age (odds ratio [OR] =1.09, 95% confidence interval [CI] =1.03-1.14), educational level (OR = 2.35, 95% CI = 1.05-5.27), and total expenditure (OR = 3.14, 95% CI = 1.06-9.37). Whereas, independent predictors for increased the likelihood of central obesity were age (OR = 1.12, 95% CI = 1.06-1.18), marital status (OR = 6.44, 95% CI = 1.94-21.40), low education (OR = 0.38, 95% CI = 0.16-0.91), number of rooms (OR = 1.19, 95% CI 1.03-3.45), and self-regulation score (OR = 0.94, 95% CI = 0.88-1.00). CONCLUSIONS: The socioeconomic determinants, especially age, level of education, and expenditure, as well as self-regulation, play an important role in excess weight and central obesity among women. Therefore, further research is needed to reach women in different SES groups with a variety of interventions through concurrent triangulation of longitudinal studies and qualitative research.

Application of the theory of reasoned action to promoting breakfast consumption.

BACKGROUND: Breakfast is the most important daily meal, but neglected more than other meals by children and adolescents. The aim of this study was to evaluate the effectiveness of an educational intervention, based on the Theory of Reasoned Action (TRA) to increase breakfast consumption among school children in Bandar Abbas, Iran. METHODS: In this quasi experimental study which was conducted in 2012, 88 students of four secondary schools in Bandar Abbas, south of Iran, were enrolled. Multi-stage cluster sampling was performed with random allocation of interventional and control groups. The study tool was a questionnaire which was filled by the students before and two months after the educational intervention. For data analysis, statistical tests including paired-samples t-test, independent samples t-test, Wilcoxon test, and Mann-Whitney test were used through SPSS v.18 software. RESULTS: The result of the study showed that application of TRA significantly increased scores of behavior of breakfast consumption (p<0.01). After the intervention, a significant increase was revealed in all nutrition intakes, except for fat and sugar (p<0.01). CONCLUSION: The findings support application of the TRA in improving the intention and behavior of breakfast consumption. Applying this theory for designing interventions to increase breakfast eating is recommended.
