RESUMO

BACKGROUND: Iron deficiency anemia (IDA) is a global health challenge, especially affecting females and children. We aimed to conduct an umbrella systematic review of available evidence on IDA's prevalence in Iranian pregnant women and children. METHODS: We searched the Web of Science, Science Direct, PubMed, Scopus, and Google Scholar databases for articles published by April 2023. Meta-analyses investigating the status of IDA in Iran were included. The findings of seven meta-analyses comprising 189,627 pregnant women with a mean age of 26 and 5,890 children under six years old were included in this study. The methodological quality of each study was evaluated with the Assessment of Multiple Systematic Reviews (AMSTAR2) instrument. RESULTS: We estimated the prevalence of IDA at 15.71% in pregnant women and 19.91% in young children. According to our subgroup analysis of pregnant women, IDA's prevalence in urban and rural regions was 16.32% and 12.75%; in the eastern, western, central, southern, and northern regions of Iran, it was estimated at 17.8%, 7.97%, 19.97%, 13.45%, and 17.82%, respectively. CONCLUSION: IDA is common in young children and pregnant females and is a significant public health concern in Iran. The present umbrella review results estimated that Iran is in the mild level of IDA prevalence based on WHO classification. However, due to sanctions and high inflation in Iran, the prevalence of anemia is expected to increase in recent years. Multi-sectoral efforts are required to improve the iron status of these populations and reduce the burden of IDA in the country.

RESUMO

This study aimed at investigating the parasitic contamination of fresh leafy vegetables in Tehran, Iran, during 2020-2021. A cross-sectional study was conducted and 180 fresh leafy vegetables (including leek, watercress, mint, spring onion, radish, basil, parsley, lettuce, and spinach) were collected randomly in the five regions of Tehran, Iran. Each 200-g sample was soaked with tap water containing detergent, and the obtained sediment was centrifuged and examined for parasitic stages using a light microscope. The overall rate of parasitic contamination was 19.4%, with Trichostrongylus and Toxocara eggs being the most prevalent parasites (3.9%) and the highest rate of parasitic contamination was observed in spinach (40%), whereas no contamination was found in spring onions. Except for radish, other vegetable samples had multiple parasitic infections. Due to the contamination of vegetables, it is necessary to have a suitable method to reduce the parasites. Consequently, policymakers should safeguard public health by consistently monitoring contaminants in food and prioritizing education and research on methods to mitigate their presence in the food chain.

RESUMO

Eggs are a high-quality, nutrient-dense source of protein that is available at a relatively low price and the contamination of eggs by heavy metals is an important issue in public health. This review aimed to assess the risk of heavy metal pollutants in Iranian hen eggs. Original full-text available studies in Iran, detecting levels of Pb, Cd, As, and Hg in whole or part of the egg, and published between January 2000 and March 2023 were selected based on the inclusion criteria. The random-effect model was used to estimate the pooled concentrations of Pb, Cd, As, and Hg in Iranian eggs in meta-analysis. The incremental lifetime cancer risk (ILCR) and the target hazard quotient (THQ) were estimated by both calculation and Monte Carlo simulations to determine the carcinogenic and non-carcinogenic risk of egg consumption, respectively. The pooled concentrations of heavy metals in Iranian hen eggs from nine articles (11 datasets: 10 studies on Pb, 7 on Cd, and 5 on As and Hg concentrations) were Pb 0.29 (95% CI 0.20-0.39) mg kg-1, Cd 0.04 (95% CI 0.03-0.06) mg kg-1, As 0.05 (95% CI 0.03-0.07) mg kg-1, and Hg 0.03 (95% CI 0.02-0.04) mg kg-1. THQ did not show the non-carcinogenic risk; however, the ILCR for Pb concentration showed the threshold carcinogenic risk (mean ILCR = 8.94e - 4 and 9.0E - 4 by calculation and Monte Carlo simulations, respectively), with the greater risk for Cd (mean ILCR = 2.02e - 2). The carcinogenic risk of Pb and Cd concentration in Iranian hen eggs shows the urgent need for programs and policies to lower the risk for consumers by providing healthier feeding.

RESUMO

BACKGROUND: This study was conducted to assess the concentration of heavy metals (arsenic and mercury) and estimate the probability that consumption of hen egg products collected in Iran has carcinogenic or non-carcinogenic consequences. METHODS: A total of eighty-four hen eggs from 21 major brands were randomly selected from among thirty local supermarkets in two seasons (winter (January) and summer (August) 2022). Arsenic (As) and Mercury (Hg) was determined by using ICP-MS. The human health risk assessment refers to the formulation of the USEPA standard focused on Estimated Daily Intake (EDI), International Lifetime Cancer Risk (ILCR), Target Hazard Quotient (THQ), and Monte Carlo simulation (MCS) as a probabilistic method. Data analysis was carried out using the statistical software SPSS. Differences in mean concentrations of As and Hg in two seasons were tested by paired t-test. RESULTS: Over two seasons, the average As and Hg concentrations in hen eggs were 0.79 and 0.18 µg.kg-1, respectively. Seasonal difference in As concentration (p = 0.451) was not significant, whereas that of Hg concentration (p < 0.001) was significant. The calculated value of EDI was 0.29 µg As/day and 0.06 µg Hg/day. The EWI in the maximum scenario of as level in hen eggs was estimated to be 8.71 µg As and 1.89 µg Hg/month for Iranian adults. THQ's mean for As and Hg in adults was determined to be 0.00385 and 0.00066, respectively. In addition, ILCRs by MCS for As were 4.35E-4. CONCLUSION: In total, the result indicates that there was not a significant risk of developing cancer; the calculation of THQ was still below the accepted level of 1, indicating that there was no risk while, according to most regulatory programs (ILCR > 10- 4) shows a threshold carcinogenic risk of arsenic through consuming in hen eggs. Therefore, policymakers need to be aware that it is prohibited to establish chicken farms in heavily polluted urban areas. It is essential to regularly conduct examinations to measure the presence of heavy metals in both ground waters used for agriculture and the feed provided to chickens. Additionally, it is advisable to focus on raising public awareness about the importance of maintaining a healthy diet.

RESUMO

The hen egg is one of the main sources of cheap, great quality, and nutritious food. This study aimed at determining the level of lead (Pb) and cadmium (Cd) in hen eggs and at assessing the carcinogenic and non-carcinogenic risks caused by the consumption of hen eggs collected in Iran. A total of 42 hen eggs from 17 major brands were randomly sampled from supermarkets. Lead and cadmium concentrations were determined by using inductively coupled plasma mass spectrometry (ICP-MS). Additionally, using the Monte Carlo simulation (MCS) method to calculate dietary exposure, target hazard quotient (THQ), and incremental lifetime cancer risk (ILCR), the related human health risk associated with ingesting these hazardous metals for adults was evaluated. The average Pb and Cd concentrations in whole eggs were 7.16 ± 0.248, and 2.83 ± 0.151 µg kg-1, respectively, which were less than the maximum permitted levels, established by FAO/WHO and the Institute of Standards and Industrial Research of Iran (ISIRI). Pb and Cd concentrations were significantly correlated at the 0.05 level (r = 0.350). Regarding the levels of Pb and Cd in eggs, overall, the estimated weekly intake (EWI) of these metals for adults by egg consumption was determined 0.014 and 0.007 mg/week, respectively, which were lower than the risk values suggested. The carcinogenic and non-carcinogenic indexes of Cd and Pb indicated that the adult population in Iran was safe (THQ Pb and Cd <1, ILCR <10-6 Pb). It should be emphasized that this research primarily focuses on egg consumption, which may account for a relatively small portion of Iranian consumers' overall exposure to Pb and Cd. Therefore, a comprehensive study on the risk assessment of these metals through whole-diet foods is recommended. The findings showed that lead and cadmium levels in all evaluated eggs were suitable for human consumption. Adults' Pb and Cd exposure from eating eggs was significantly lower than the risk levels established by Joint FAO/WHO Expert Committee on Food Additives (JECFA), per the exposure assessment. According to the THQ values of these dangerous metals, which were below one value, egg eating by Iranian consumers does not present a non-carcinogenic risk. In addition, this finding provides accurate and reliable information for policymakers to improve food safety status to reduce public health hazards.

RESUMO

BACKGROUND: food insecurity (FI) is considered as an essential public health problem which may have detrimental effects on people's health. The aim of present study was to evaluate FI, body mass index, quantity and quality of food intake in lactating and non-lactating mothers with children under two years. METHODS: in this cross-sectional study 307 mothers (237 lactating and 70 non-lactating) were participated. Socio-economic and demographic information were gathered by questionnaires. FI of families was evaluated by the questionnaire of the United States Department of Agriculture (USDA) Household Food Security. For assessing quality and quantity of food intake of mothers, dietary diversity score (DDS), diet quality index-international (DQI-I) and nutrient adequacy ratio (NAR) were calculated. Weight and height of participants were measured and body mass index (BMI) was calculated. Finally, Chi-squared test, analysis of variance (ANOVA) and linear regression were used for statistical analysis. RESULTS: in this study the rate of underweight, normal weight, overweight, and obesity in mothers was 0.3%, 39.2%, 42.3%, and 18.2%, respectively. Among the determinants of BMI, household food security status had the greatest effect (Beta=-1.584, P < 0.001) and mother age had the least effect (Beta = 0.101, P = 0.013). Mother's occupational and educational status, having facilities, physiological status of mother, and house size had significant correlation with NAR. Mother's occupational and educational status, and having facilities had significant relationship with DDS, too. Also, the significant correlation of Mother's education, having facilities, and physiological status of mother with DQI-I were found. CONCLUSIONS: we found that Household food security status had the most effect on BMI of mothers. In this study, the best nutrient adequacy and dietary diversity were found in the obese group and the most diet quality was found in the normal weight group.

RESUMO

Objective: This study aimed at analyzing the effectiveness of the policy of taxing Sugar-Sweetened Beverages (SSBs) on their purchases during the last decade in Iranian households. Methods: The present mixed method study was done in 2017 in four phases: (1) A meta-review of the fiscal policies during the last decade, (2) Collecting existing data on soft drinks' production, price, and household expenditure during the last decade, (3) Conducting 19 semi-structured interviews with key informants, and (4) Facilitating a national meeting to achieve a consensus on the recommendations and future implications. Results: Document reviews showed that based on the Permanent Provisions of National Development Plans of Iran, the Ministry of Health and Medical Education (MOHME) should announce the list of health threatening products to increase taxation for them. The government is allowed to impose taxes on domestically produced and imported SSBs. The average household expenditure on SSBs increased in the rural and urban households of Iran during 2006-2016 in spite of taxation. In the different key informants' opinion, only value-added tax (VAT) was implemented among different fiscal policies, and the other parts, including tax and tolls were debated. Conclusion: The present research findings further proposed some suggestions for increasing the effectiveness of financial policies in reducing the prevalence of NCDs in Iran.

RESUMO

BACKGROUND: Food insecurity (FI) is associated with dietary practices, which can act as a risk factor for dental caries. AIM: This study aimed to investigate the relationship between FI and dental caries prevalence in children and adolescents. DESIGN: MEDLINE (via PubMed), EMBASE, SCOPUS, ISI web of knowledge, Cochrane, and ProQuest Dissertations & Theses Global database (up to April 19, 2022) as well as reference lists were searched. Eligible studies compared dental caries prevalence in food-secure and food-insecure individuals younger than 19 years. Two independent reviewers performed study selection, data extraction, and risk of bias assessment using a modified Newcastle-Ottawa Scale. Meta-analysis was performed, and the pooled odds ratio (OR) was calculated at 95% confidence interval (95% CI). RESULTS: Among the 1350 retrieved records, 10 cross-sectional reports were selected for systematic review. Six studies involving 8631 participants were included in the meta-analysis. More than half of the reports were published within the period 2019-2021. All studies except one were judged as low risk of bias. Overall, the prevalence of dental caries was greater among the food-insecure children and adolescents (OR: 2.01, 95% CI: 1.52-2.65, p < .001, I2 : 73.5%). Similarly, all three categories of FI were significantly associated with caries experience (marginal FI: OR: 1.88, 95% CI: 1.56-2.27, p < .001, I2 : 0.0%; low FI: OR: 2.42, 95% CI: 1.42-4.14, p = .001, I2 : 74.4%; very low FI: OR: 2.37, 95% CI: 1.88-3.00, p < .001, I2 : 0.0%). CONCLUSION: The results showed a significant association between FI status and dental caries in both childhood and adolescence; however, there was a lack of longitudinal studies for a better understanding of this association. Health policies leading to reduction in FI may also aim to reduce dental caries.

RESUMO

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.

RESUMO

BACKGROUND: An association has already been hypothesized between iron, copper, and magnesium status assessed through food frequency questionnaires (FFQs) and the risk of esophageal squamous cell carcinoma (ESCC). However, self-reported dietary assessment methods are prone to measurement errors. We studied the association between iron, copper, and magnesium status and ESCC risk, using hair samples as a long exposure biomarker. METHODS: We designed a nested case-control study within the Golestan Cohort Study, that recruited about 50000 participants in 2004-2008, and collected biospecimens at baseline. We identified 96 incident cases of ESCC with available hair samples. They were age-matched with cancer-free controls from the cohort. We used inductively coupled plasma mass spectrometry (ICP-MS) to measure iron, copper, and magnesium concentrations in hair samples. We used multiple logistic regression models to determine odds ratios and 95% confidence intervals. RESULTS: Median concentrations of iron, copper, and magnesium were 35.4, 19.3, and 41.7 ppm in cases and 25.8, 18.3, and 50.0 ppm in controls, respectively. Iron was significantly associated with the risk of ESCC in continuous analysis (OR=1.41, 95% CI=1.03-1.92), but not in the tertiles analyses (ORT3 vs. T1=1.81, 95% CI=0.77-4.28). No associations were observed between copper and magnesium and ESCC risk, in either the tertiles models or the continuous estimate (copper: ORT3 vs. T1=2.56, 95% CI=1.00-6.54; magnesium: ORT3 vs. T1=0.75, 95% CI=0.32-1.78). CONCLUSION: Higher iron status may be related to a higher risk of ESCC in this population.

RESUMO

Background: A variety of factors influence seafarers' health. Such factors might affect their satisfaction with life. Aims: To examine the relationships between seafarers' mental health status and satisfaction with life by using a structural equation method. Methods: In this survey, 470 seafarers were selected via convenience sampling method from two shipping companies. Validated questionnaires including Satisfaction with Life Scale (SWLS), generalized anxiety disorder-7 (GAD-7), Post-traumatic Stress Disorder-8 (PTSD-8), Patient Health Questionnaire-9 (PHQ-9), General Health Questionnaire-12 (GHQ-12), Perceived Health status and Depression-Anxiety-Stress scale-21 (DASS-21) were used to assess different aspects of well-being and life satisfaction. The stratified path analysis method was applied to analyze the data. Results: 439 seafarers (200 officers and 237 non-officers) with a mean age of 34.5 (SD: 8.05) participated in the current study. The GHQ score directly affected satisfaction with life in both officers (ß = 0.35) and non-officers (ß = 0.40). Also, perceived health status directly and indirectly affected satisfaction with life among officers (ß = 0.19) and non-officers (ß = 0.06). While officers working days per month indirectly impacted satisfaction with life through the general anxiety disorder, perceived health status, depression, anxiety, stress and current mental health. In non-officers, generalized anxiety disorder had the most potent indirect effects on satisfaction with life through perceived health status and current mental health. Conclusion: Perceived health status, directly and indirectly, affected seafarers' satisfaction with life. Measures should be taken in order to improve seafarers' perceived health status and its effects on satisfaction with life.

RESUMO

Background: Today, food insecurity is recognized as an important public health problem that can have detrimental effects on families. Aim: The aim of this study was to assess the determinants and consequences of food insecurity in families having children under the age of 2 years. Method: In this cross-sectional study, 307 mothers and their children under the age of 2 years were selected by stratified random sampling. Demographic and socioeconomic data were collected by completing questionnaires through face-to-face interview. Household food insecurity (HFI) status was determined using the United States Department of Agriculture (USDA) household food security questionnaire. Results: Based on the results, 67.4% of families were high food secure. Low and very low food security was 25.7% and 6.9%, respectively. House size (Beta = -0.019, 95% CI: -0.029, -0.009), father's job (Beta = -4.758, 95% CI:-6.777, -2.738), father education (Beta = -0.370, 95% CI: -0.717, -0.023), and economic status (Beta = -0.628, 95% CI: -0.809, -0.448) were significantly related to the USDA total food insecurity score (p < 0.05). Regression analysis showed that children birth weight, father's body mass index (BMI), and mother's waist circumference had a significant positive correlation with weight for age (Z-score) of children. Children's birth weight, father's BMI, and HFI status had significant and positive correlation with weight for length (Z-score). Moreover, the significant association between children's birth height, mother's BMI, and mother's waist circumference with length for age (Z-score) were observed (p < 0.05). Conclusion: We found the father's job was the most effective factor in food insecurity and economic status of the family was in the second place. Also, HFI had a relationship with weight status of children under the age of 2 years.

RESUMO

BACKGROUND: Given the unprecedented nature of the COVID-19 crisis and the importance of early implementation of prevention programs, it is essential to understand better its potential impacts on various food security dimensions and indicators. METHODS: Research databases, including Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Public Health Register, PubMed/MEDLINE, SCOPUS, EMBASE, CINAHL, Web of science, and Google Scholar, will be searched using a search strategy and keywords developed in collaboration with librarians. The review will include all field and community trials and observational studies in all population groups. Searching electronic databases, study selection, and data extraction will be conducted by two researchers independently. Four critical appraisal tools will be used to assess the quality of included studies according to the study design: The Joanna Briggs Institute (JBI) Prevalence Critical Appraisal tool, the JBI critical appraisal checklist for randomized control/pseudo-randomized trial, descriptive/case series, and comparable cohort/case-control. These tools were initially designed for use in systematic reviews. A narrative synthesis will be implemented to summarize findings if meta-analyses are not appropriate. DISCUSSION: The current systematic review results can be used to predict the effect of COVID-19 on the individuals' and households' food security, especially in vulnerable populations, and develop effective interventions. This review can provide information for policymakers to better understand the factors influencing the implementation of these interventions and inform decision-making to improve food security. SYSTEMATIC REVIEW REGISTRATION: The present study registration number in the international prospective register of systematic reviews (PROSPERO) is CRD42020185843.

RESUMO

BACKGROUND: Viral infections are mostly highly contagious and may cause widespread health problems. Some studies reported that the dietary fiber (DF) may be effective in reducing the complications of viral infections in intensive care unit (ICU) patients. The present review study aimed to investigate the effect of DF on common complications in critically ill patients with viral infections. METHODS: A literature review was conducted for the published papers in English from January 2001 to July 2021 using related keywords. Studies with clinical trial or case-control design described the effects of fiber intake on the complications of viral infections in patients admitted to the ICU were collected. RESULTS: DF may reduce the mortality rate of viral infections through modulating inflammatory processes. A higher intake of DF intake may improve hyperglycemia and impaired glucose tolerance in patients with viral infections. A high-fiber formula in enteral nutrition was reported to reduce the risk of diarrhea in patients with viral infections. CONCLUSION: DF may reduce the complications of viral infections such as inflammation, diarrhea, hyperglycemia, and mortality in critically ill patients. Future longitudinal studies on the amount and type of DF are warranted.

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

This study aimed to analyze the fat, fatty acid profile, and salt content of restaurant foods (RFs) and find out strategies to lower them using the strengths, weaknesses, opportunities, and threats (SWOT). Five types of common foods (n = 70) were collected from restaurants in Tehran, Iran. The fat, fatty acid profile, and salt content of samples were analyzed by acid hydrolysis method, gas chromatography, and Charpentier Volhard methods, respectively. The quantitative data were analyzed by the SPSS using ANOVA and Spearman's correlation test. Then, a SWOT analysis was done. The laboratory results indicated that the highest amount of total fat was in Samosa (16.92% ± 6.27%), whereas saturated fatty acids (SFA) and trans fatty acids (TFA) were significantly higher in Koobideh kebab with rice (44.42% ± 5.07% and 2.86% ± 0.64%, respectively) as compared to other samples. In addition, the highest amount of salt was in the Falafel sandwich (2.87% ± 0.98%). The salt content in the majority of analyzed foods was about two times more than the daily recommendations of the World Health Organization (WHO). The SWOT analysis results showed the lack of standardization of recipes to measure accurate fat and salt content was the main weakness and food labeling in the menus was detected as an important opportunity. TFA and salt in RFs were alarmingly high and it is necessary to find strategies for reformulation of RFs to reduce their fat and salt content. Policymakers can use the SWOT analysis results of this study to offer directions for potential future strengthening actions of healthy foods in restaurants for public health.

RESUMO

BACKGROUND: Seafaring is a risky occupation with high prevalence of risk factors for non-communicable diseases. Food intake and eating habits are important cornerstones regarding health and health promotion. The aim of this study was to provide an overview of dietary intake and dietary intake assessment methods of seafarers and suggestions for applicable assessment tools. METHODS: We systematically searched PubMed and NLM Gateway (for MEDLINE), Web of Science, and SCOPUS up to February 2020 using standard keywords including nutrition OR diet OR meal AND maritime settings. Two independent reviewers extracted the data. The quality of included studies was assessed using the Joanna Briggs Institute Critical Appraisal checklist. RESULTS: From 4449 studies initially identified, 26 articles were included in the final review. Qualitative data (e.g. on unhealthy eating) had been gathered using in-depth individual or group interviews, participant observations, and phone-based chats. Composition of menu analysis, 24 h dietary recall, food diaries/ diet records, dietary habits questionnaire, food stores and food waste of the ship were used to assess the quantitative outcomes (e.g. dietary intakes). Access to meat, processed meat and egg, frozen and canned food items, sugary drinks, alcohol, greasy and salty food was high. In contrast, consumption of fruit, vegetables, dairy products, and cereals was lower than recommended. CONCLUSIONS: Eating habits and dietary intakes in maritime settings are unhealthy. Subjective dietary assessment methods combining menu analysis with new technologies (e.g. mobile-based) might be an applicable method in this hard to reach setting which is the vessels.

RESUMO

The restaurant business has turned into a dynamic and ever-growing industry. So, food safety must be a priority for these establishments, especially during the COVID-19 pandemic. The aim of this study was to determine the effect of training intervention on the health and food safety knowledge, attitude, and self-reported practice (KAP) of restaurant food handlers during the COVID-19 pandemic. This quasi-experimental study was conducted on 159 restaurant food handlers in Tehran, Iran. The training intervention was developed based on the latest global guidelines. The KAP of the subjects was measured before and after the training. Fisher's exact test, paired t test, and repeated measures ANOVA were used for statistical analysis. Data analysis was done using the IBM_SPSS software. The total knowledge scores of participants were low (17.6%), moderate (35.2%), and good (47.2%) before training, which were changed to 5% (low), 23.9% (moderate), and 71.1% (good) after training. The total pretraining attitude scores were 0.6, 77.4, 18.2, and 3.8% that were changed to 0% (strongly negative), 49.1% (negative), 33.3% (positive), and 17.6% (strongly positive), respectively. Also, the self-reported practice scores of the participants before training were 1.3, 56, and 42.7 that were changed to 0% (weak), 26.4% (acceptable), and 73.6% (desirable) after the intervention, respectively. Paired t test results showed a statistically significant increase in all scores. The interaction of training with age and education was statistically significant in increasing the knowledge and attitude scores of the participants by the repeated measures ANOVA. Improving the KAP of food handlers by health and food safety training can improve the status of restaurants and minimize the outbreak of pandemic diseases, including COVID-19, which is an effective step in community health. Thus, it is an urgent need for policymakers to design an online system of continuous food safety training for food handlers.

RESUMO

BACKGROUND: About 30% of children < 5 years old are estimated to experience vitamin A deficiency worldwide. Globally, vitamin A deficiency can be reduced by five major interventions: supplementation, dietary modification, fortification, promotion of both public health, and breastfeeding. This prospective policy analysis (Prospective policy analysis focuses on the future outcomes of a proposed policy. Adapted from Patton, CV, and Sawicki DS. Basic Methods of Policy Analysis and Planning, Prentice-Hall, Inc. New Jersey,1993). (Patton A, Carl V, and David S. Basic methods of policy analysis and planning, prentice-hall, 3th ed. 2012) aimed to identify evidence-based policy options to minimize prevalence (VAD) among 15-23 months-children in Iran. METHODS: Thirty-eight semi-structured face-to-face interviews were held with experts at high, middle, and low managerial levels in Iran's health system, as well as at Schools of Nutrition Sciences and dietetics, using purposive and snowball sampling. All interviews were recorded by a digital voice recorder and then transcribed, codified, and eventually analyzed using a mixed approach (inductive-deductive) by MAXQDA software version 10. RESULTS: Most policies related to VAD reduction in this age group are supplementation, expansion of education, and awareness. Three main factors affecting VAD reduction policies emerged from the analysis: basic factors (governance, infrastructure, and organization), underlying factors (social factors, economy), and immediate factors (services). Due to its cross-sectoral nature, evaluating the results of the implementation of this policy requires strong and coherent inter-sectoral cooperation. The existing primary healthcare network (PHC) is a crucial means for successful implementation of policies to address VAD in Iran. CONCLUSIONS: In addition to supplementation and assistance in this age group, other policies should be also planned to reduce VAD in various regions. In addition to the Ministry of Health & Medical Education (MoHME), other actors need to be involved, we advocate, throughout the entire policymaking process of policy-making to reduce VAD in Iran.
