Efectos de la promoción de estilo de vida saludable en los médicos generales del Instituto Oncológico Nacional marzo-abril 2021

Introduction: The medical population is considered a representation of integral health. Its work characteristics predispose each member to be complicit in an unconscious practice and promotion of an unhealthy lifestyle. The aim of this work was to describe the effects on lifestyle of an educational intervention in general practitioners in an active work environment. Methods: This study included 18 general practitioners working at the “Instituto Oncológico Nacional de Panamá”. It consisted of 10 virtual educational sessions delivered by trained professionals for 2 months. Results: Positive changes and improvement in all measured variables were reported, including increased frequency of exercise sessions, increased duration of each session, increased consumption of fruits, vegetables, legumes and seeds, increased hours of sleep, improvement in the perceived stress scale score and a decrease in the consumption of foods with low nutritional quality. Discussion: Truly little evidence exists regarding lifestyle promotion educational interventions aimed at health professionals. This population has a high predisposition to form a poor-quality lifestyle since the work environment in which the physician develops exposes him/her to adverse situations such as rotating schedules and long working hours with sleep deprivation. Conclusions: This practical and low-cost educational intervention achieved improvements in the lifestyle of physicians. For this reason, we recommend the replication of similar interventions and their documentation.

Risk Factors and Symptoms of Ovarian Cancer in Patients Attending Hiwa Oncology/Hematology Hospital in Sulaimaniyah City

Background: Ovarian cancer is responsible for higher mortality rate than any other cancer of the woman genital system. 
 Aims of the study: this study aims to find the risk aspects and symptoms of ovarian cancer in patients visiting Hiwa Oncology/Hematology hospital in Sulaimaniyah City. 
 Methodology: This study was a retrospective case-control study conducted in Hiwa Oncology / Hematology Hospital in Sulaimaniyah city, Northern Iraq, the period of the study was 1 / July / 2019 to 1 / march / 2020, based on the recorded database system of Hiwa Oncology / Hematology Hospital from 2013 - 2019, involving 100 diagnosed patients and 200 healthy women as control. Personal information such as age, education, economic status, cigarette smoking, height, weight, diet and eating habits, and used oral contraceptive pills were collected. 
 Results: The incidence of ovarian cancer in 2013 was 13 cases which increased to 83 cases in 2019. The highest percentage (30%) of patients' age range were 40- 49 years (p = 0.004). Most cases 60% had an insufficient economic state and 33 % of cases were illiterate women. Passive smoking appeared to be more prone to ovarian cancer: especially those with a smoking duration of > 5 years. Additionally, 68% of patients used oral contraceptive pills with a duration range of 1-5 years. Also, a highly significant correlation between diet and ovarian cancer was found in patients. The majority of the patients (76%) complained of abdominal pain and abdominal distension as the first presenting symptoms of ovarian cancer. 
 Conclusion: This study concluded that age, economic status, educational level, height, passive smoking, weight, diet, and oral contraceptive pill usage were directly accompanied by the possibility of ovarian cancer. 
 Recommendations: All women especially those after age of 40 years old, should pay attention to education and health awareness including symptoms and causes of ovarian cancer, especially attention to decrease weight and passive smoking and using a healthy diet through decrease consumption the sweets, dairy products, and animal fat and increase consumption of legumes, fish meat, vegetable and fruits. 

Socioeconomic, Eating- and Health-Related Limitations of Food Consumption among Polish Women 60+ Years: The 'ABC of Healthy Eating' Project.

The study aimed at identifying the socioeconomic, eating- and health-related limitations and their associations with food consumption among Polish women 60+ years old. Data on the frequency of consumption of fruit, vegetables, dairy, meat, poultry, fish, legumes, eggs, water and beverages industrially unsweetened were collected with the Mini Nutritional Assessment (MNA®) and were expressed in the number of servings consumed per day or week. Three indexes: the Socioeconomic Status Index (SESI), the Eating-related Limitations Score (E-LS) and the Health-related Limitations Score (H-LS) were developed and applied. SESI was created on the base of two variables: place of residence and the self-reported economic situation of household. E-LS included: difficulties with self-feeding, decrease in food intake due to digestive problems, chewing or swallowing difficulties, loss of appetite, decrease in the feeling the taste of food, and feeling satiety, whereas H-LS included: physical function, comorbidity, cognitive function, psychological stress and selected anthropometric measurements. A logistic regression analysis was performed to assess the socioeconomic, eating-, and health-related limitations of food consumption. Lower socioeconomic status (vs. higher) was associated with a lower chance of consuming fruit/vegetables ≥ 2 servings/day (OR = 0.25) or consuming dairy ≥ 1 serving/day (OR = 0.32). The existence of multiple E-LS limitations (vs. few) was associated with a lower chance of consuming fruit/vegetables ≥ 2 servings/day (OR = 0.72), consuming dairy ≥ 1 serving/day (OR = 0.55) or consuming water and beverages industrially unsweetened ≥6 cups/day (OR = 0.56). The existence of multiple H-LS limitations was associated with a lower chance of consuming fruit/vegetables ≥ 2 servings/day (OR = 0.79 per 1 H-LS point increase) or consuming dairy ≥ 1 serving/day (OR = 0.80 per 1 H-LS point increase). Limitations found in the studied women were related to insufficient consumption of selected groups of food, which can lead to malnutrition and dehydration. There is a need for food policy actions, including practical educational activities, to eliminate barriers in food consumption, and in turn to improve the nutritional and health status of older women.

Shifting to a Sustainable Dietary Pattern in Iranian Population: Current Evidence and Future Directions.

The need for a shift in diet toward a more sustainable one has reached an urgency in certain regions, including Iran, due to more rapid climate change and a higher level of vulnerability. This study was undertaken to identify and summarize available data on changes required in the current Iranian diet to make it more sustainable and the extent to which current policies in the country have addressed such a shift. In this study, PubMed, Scopus, and Web of science, as well as Iranian scientific search engines, including Scientific Information Database and Magiran, were systematically searched from January 1990 to July 2021. A total of 11 studies and policy analyses were included in this study. Based on the findings, moving Iranian diet toward sustainability will require increase in consumption of dairy, fruits, vegetables, cereals, poultry, and legumes and decrease in consumption of bread, rice, pasta, red meat, eggs, fats, sugars, and sweets. There has been a great deal of effort and investment on policies and strategies to decrease the amount of sugar, salt, and fat (specifically trans-fatty acids) in the Iranian diet, which makes it more sustainable healthwise. Several policies and programs have been implemented to tackle non-communicable diseases (NCDs) by reducing access to unhealthy foods, which is in line with health dimension of a sustainable diet. However, there is almost no direct address to ecological aspect of sustainable diet in the food and nutrition policy documents in the ccountry. Development of an enabling environment to a sustainable diet will require policy and actions to improve public awareness, support study to provide evidence and identify possible alternatives, and plan and implement interventions/programs to promote and facilitate healthy and sustainable diets.

Evolution of Nutritional Habits Behaviour of Spanish Population Confined Through Social Media.

Introduction: In Spain, on 14 March 2020, a state of alarm is declared to face the health emergency situation caused by the COVID-19 coronavirus, limiting the freedom of movement of people. The Spanish population is confined.Objective: With this situation, “NUTRITIONAL HEALTH IS NOT CONFINED” arises a research project that seeks to promote nutritional education based on the pattern of the Mediterranean diet (MD) using new computer technologies. It is about providing the population with the information of general interest about the promotion of a healthy diet through social networks and analysing the impact of its dissemination, in the form of a longitudinal intervention study of the Spanish nutritional evolution during confinement, with a daily survey format, and it is intended to assess food consumption during the period of confinement. Materials and methods: In total, 936 participants were asked every day. Short publications were published every day based on the scientific evidence (FAO, WHO, AECOSAN) through social media such as Instagram, accompanied by a questionnaire of 11 questions (yes/no) where it was intended to assess the evolution of daily consumption.Results and Discussion: The diffusion through social media has allowed to have a greater reach of the population. We observed that mood throughout confinement generally improves. There are certain eating habits from the MD that are well established in the daily diet of our population, such as the consumption of fruits, vegetables, legumes, dairy products, and eggs. It seems that enjoying good health is a growing concern in pandemic situations, which is why inappropriate behaviours such as “snacking” between meals or the consumption of processed foods such as snacks, industrial pastries, soft drinks, and sweets are avoided, increasing the amount of healthy food such as meat and fish. This study opens up future avenues of research promoting MD and implements new cohort nutritional databases, especially about young adult people, who are adept at navigating digital spaces and therefore using social media.

A healthy eating score is inversely associated with depression in older adults: results from the Chilean National Health Survey 2016-2017.

To investigate the relationship of a healthy eating score with depression in Chilean older adults. Cross-sectional study. Older adults from the Chilean National Health Survey 2016-2017. Associations were analysed using complex samples multivariable logistic regressions adjusted for age, sex, socio-demographic, lifestyles (physical activity, smoking, alcohol consumption and sleep duration), BMI and clinical conditions (hypertension, diabetes, hypercholesterolaemia and cardiovascular diseases). The number of participants was 2031 (≥ 60 years). The Composite International Diagnostic Interview-Short Form was applied to establish the diagnosis of major depressive episode. Six healthy eating habits were considered to produce the healthy eating score (range: 0-12): consumption of seafood, whole grain, dairy, fruits, vegetables and legumes. Participants were categorised according to their final scores as healthy (≥ 9), average (5-8) and unhealthy (≤ 4). Participants with a healthy score had a higher educational level, physical activity and regular sleep hours than participants with an average and unhealthiest healthy eating score. Participants classified in the healthiest healthy eating score had an inverse association with depression (OR: 0·28, (95 % CI 0·10, 0·74)). Food items that contributed the most to this association were legumes (15·2 %) and seafood (12·7 %). Older adults classified in the healthiest healthy eating score, characterised by a high consumption of legumes and seafood, showed a lower risk for depression in a representative sample of Chilean population.

Antioxidant capacity and diet pattern evaluation in a university community in south eastern Spain.

Background: antioxidants can eliminate excess free radicals present in our bodies, and it has been shown that eating a diet rich in polyphenols and anthocyanins, present in vegetables, fruits and legumes, has a protective effect against cancer, heart disease, and some neurological diseases. Objectives: the objective of the present work was to evaluate the eating habits of the university community in Murcia. Methods: the research was carried out by means of surveys on the choice of dishes at university canteens. In addition, the antioxidant activity of the most widely consumed dishes (pork Milanese style, pasta Bolognese, lentil and chorizo stew, Spanish omelette, and vegetable paella) were evaluated using the DPPH, FRAP, and ORAC methods. Results: the results obtained indicated that canteen users preferred consumption of pasta, meat, and fried potatoes rather than vegetables, pulses, and fish as main courses. The most consumed dessert was yogurt, closely followed by fruits. The consumption of water also stands out, and a majority of subjects accompanied their meals with white bread and salad. With regard to antioxidant capacity, it was found that the dish with the highest antioxidant capacity was lentil and chorizo stew, with Spanish omelette being the less antioxidant dish. Conclusion: in conclusion, consumption of fruit, vegetables, and legumes should be encouraged, as they contribute decisively to the antioxidant capacity of the diet.

Lack of association between nuts and legumes consumption and metabolic syndrome in young Iranian nurses.

Most studies have investigated the association between dietary pattern and risk of metabolic syndrome. Limited studies have examined the association between nuts and legumes as a food group and metabolic syndrome. This study explored the association between nuts and legumes and components of metabolic syndrome in Iranian nurses. This cross-sectional study included a representative sample of 420 female nurses of Isfahan who were randomly selected. Nuts and legumes consumption was assessed using a validated dish-based semi quantitative food frequency questionnaire (FFQ). Metabolic syndrome was defined by the National Cholesterol Education Program's Adult Treatment Panel III (ATP III). Linear and logistic regression tests were used to study the association between nuts and legumes consumption and metabolic syndrome and its components. Mean age of study participants was 35 years. The prevalence of the metabolic syndrome among study participants was 3.6%. Consumption of nuts and legumes was not associated with waist circumference either before (β=-0.01, P=0.24) or after adjusting for potential confounders (β=-0.18, P=0.41). The same findings were also observed for diastolic blood pressure (DBP) (β=0.001, P=0.42), serum triglyceride (TG) (β=0.07, P=0.32), high-density lipoprotein cholesterol (HDL-C) (β=0.008, P=0.65) and fasting blood sugar (FBS) (β=-0.001, P=0.94). We failed to find a significant association between consumption of nuts and legumes and systolic blood pressure (SBP) after adjusting for confounders (β=0.002, P=0.38). Individuals in the highest category of nuts and legume consumption did not had elevated odds for metabolic syndrome after adjusting for potential confounders (OR=0.89, 95% CI=0.08-9.80, P=0.93). Nuts and legumes consumption was not associated with metabolic syndrome or its components. Prospective studies are needed to investigate further this association.

Transitions to Legume-Based Agrifood Systems – Stakeholders' Views from Hungary

The pressing need for the radical transformation towards more sustainable agricultural and food systems, which only recently gained substantially more acknowledgement, staged several underutilised crops in new roles. Legumes have become the primary focus of research and analytical attention first in agroecology, and lately in international policy communities and the social sciences. With their effortless talent to fix nitrogen into the soil, substitute animal protein, reduce greenhouse gas emissions, legumes are now recognised as forgotten stars, that could help both agriculture and the food industry become more ecological. However, legume production and consumption, albeit multiple advantages, remain still marginal in Europe for several reasons. This article adopts an interpretative policy framework to address the legume paradox, that is our legume-dependent agri-food systems relying on imports and simultaneously maintaining deficient production and consumption of legumes. We reviewed the state of the art of legume-based food systems in Hungary by analysing conceptual frameworks and data from exploratory mixed-method research. In a case study research, we analysed the root causes of this state-of-the-art through mapping the understanding of challenges and potentialities of legume value chains in Hungary by critical stakeholders. Our primary research question is what is at play behind and how Hungarian stakeholders make meaning of this paradox. We also explore how the current trends could still open pathways for more legumes in production and consumption. Drawing on insights from the literature and stakeholder interviews in Hungary, we show an extremely locked-in agri-food system. Our results indicate that especially small scale producers face difficulties to tackle with shallow yield stability of legumes. Their struggle is further aggravated by the dumping of cheap import of plant-based protein food and feed and inorganic nitrogen fertilisers, virtually absent small-scale processing, consumers' unawareness of legumes' benefits and preoccupation with their gut discomfort and food services' unwillingness to experiment with tasty plant-based protein food. We suggest several future research topics and pathways to promote more sustainable legume-based food systems. In conclusion, we argue that any transition towards legume-based food and feed systems would initially require the mutual engagement of multiple stakeholders in the value chains, strong policy support orchestrated by public institutions.

Adherence to Mediterranean diet and advanced glycation endproducts in patients with diabetes.

BACKGROUNDIn recent years, American Diabetes Association started to strongly advocate the Mediterranean diet (MD) over other diets in patients with diabetes mellitus (DM) because of its beneficial effects on glycemic control and cardiovascular (CV) risk factors. Tissue levels of advanced glycation endproducts (AGEs) emerged as an indicator of CV risk in DM. Skin biopsy being invasive, the use of AGE Reader has been shown to reflect tissue AGEs reliably.AIMTo examine the association between adherence to MD and AGEs in patients with DM type II.METHODSThis cross-sectional study was conducted on 273 patients with DM type II. A survey questionnaire was composed of 3 separate sections. The first part of the questionnaire included general data and the habits of the participants. The second part aimed to assess the basic parameters of participants’ diseases and associated conditions. The third part of the questionnaire was the Croatian version of the 14-item MD service score (MDSS). AGEs levels and associated CV risk were measured using AGE Reader (DiagnOptics Technologies BV, Groningen, The Netherlands).RESULTSA total of 27 (9.9%) patients fulfilled criteria for adherence to MD, with a median score of 8.0 (6.0-10.0). Patients with none/limited CV risk had significantly higher percentage of MD adherence in comparison to patients with increased/definite CV risk (15.2% vs 6.9%, P = 0.028), as well as better adherence to guidelines for nuts (23.2% vs 12.6%, P = 0.023) and legumes (40.4% vs 25.9%, P = 0.013) consumption. Higher number of patients with glycated hemoglobin (HbA1c) < 7% adhered to MD when compared to patients with HbA1c > 7% (14.9% vs 7.3%, P = 0.045). Moreover, those patients followed the MDSS guidelines for eggs (33.0% vs 46.8%, P = 0.025) and wine (15.6% vs 29.8%, P = 0.006) consumption more frequently. MDSS score had significant positive correlation with disease duration (r = 0.179, P = 0.003) and negative correlation with body mass index (BMI) values (r = -0.159, P = 0.008). In the multiple linear regression model, BMI (β ± SE, -0.09 ± 0.04, P = 0.037) and disease duration (β ± SE, 0.07 ± 0.02, P < 0.001) remained significant independent correlates of the MDSS score. Patients with HbA1c > 7% think that educational programs on nutrition would be useful for patients in significantly more cases than patients with HbA1c < 7% (98.9% vs 92.6%, P = 0.009).CONCLUSIONAlthough adherence to MD was very low among people with diabetes, we demonstrated that adherence to MD is greater in patients with lower CV risk, longer disease duration, and well-controlled glycaemia.

Association of Dietary Patterns with Cognitive Function and Cognitive Decline in Sydney Memory and Ageing Study: A Longitudinal Analysis

BackgroundThe relationship of dietary patterns to cognitive health in older adults has attracted much research attention. However, results from existing studies are inconclusive. ObjectiveThe aim of this study was to investigate the association between dietary patterns and overall cognitive performance and cognitive change over time. DesignThis analysis was conducted as part of the longitudinal Sydney Memory and Ageing study with 6 years’ follow-up. Mediterranean diet and Dietary Approaches to Stop Hypertension diet scores were generated based on dietary intake for each individual, assessed by the Dietary Questionnaire for Epidemiological Studies Version 2. Participants/settingThis longitudinal study comprised 1037 community dwelling nondemented participants aged 70 to 90 years at baseline (September 2005 to December 2007), recruited from Sydney, Australia. Main outcome measuresNeuropsychological tests assessed global cognition and 6 cognitive domains on 4 occasions, at baseline and 2, 4, and 6 years later. Statistical analyses performedLinear mixed-model analyses were conducted to examine the relationship between dietary scores, food components, and overall cognitive function and cognitive change over 6 years. ResultsNo associations of Mediterranean or Dietary Approaches to Stop Hypertension dietary scores with overall cognition and cognitive decline over 6 years were found. Higher intake of legumes and nuts was related to better overall performance in global cognition (β = .091; 95% CI: 0.035-0.146; P = .001) and to multiple cognitive domains and to less decline in global cognition (β = −.016; 95% CI: −0.032 to −0.001; P = .032). ConclusionStudy findings suggest that greater consumption of legumes and nuts may be important to slow cognitive decline with age.

Has COVID-19 Changed the Lifestyle and Dietary Habits in the Spanish Population after Confinement?

Since 2020, the world has been immersed in a change in lifestyle (social, lifestyle, nutri-tion and physical activity patterns), due to the appearance of COVID-19 and the strict mobility measures which were implemented to prevent its spread. All these changes had a nutritional impact on people, modifying their dietary guidelines. This cross-sectional study was carried out to assess whether dietary habits, lifestyle, and adherence to the Mediterranean diet among the Spanish adult population (25–65 years old) during confinement was modified during the post-confinement period, using an e-survey through social networks, involving 510 subjects. A decrease in the intake of ultra-processed products, with a correlation between weekly food delivery orders at home and the consumption of salty snacks, sugary drinks, and processed pastries was also recorded. Most of the subjects performed physical exercise on a regular basis, maintaining the body weight in half of the participants. During the post-confinement period a substantial proportion of the population had healthy lifestyle and dietary habits, including the adequate consumption of fruits, vegetables and legumes; adequate time was spent preparing meals and the population did not regularly order food at home, which in the long term, reduced the risk of several diseases.

Patterns of Legume Purchases and Consumption in the United States.

Background: Legumes are an inexpensive, healthy source of protein, fiber, and micronutrients, have low greenhouse gas and water footprints, and enrich soil through nitrogen fixation. Although higher legume consumption is recommended under US dietary guidelines, legumes currently comprise only a minor part of the US diet.Objectives: To characterize the types of legumes most commonly purchased by US consumers and patterns of legume purchases by state and region, seasonality of legume purchases, and to characterize adults that have a higher intake of legumes.Methods: We examined grocery market, chain supermarket, big box and club stores, Walmart, military commissary, and dollar store retail scanner data from Nielsen collected 2017–2019 and dietary intake from the National Health and Nutrition Examination Survey (NHANES), 2017–2018.Results: The five leading types of legumes purchased in the US were pinto bean, black bean, kidney bean, lima bean, and chickpea. The mean annual per capita expenditure on legumes based on grocery purchases was $4.76 during 2017–2019. The annual per capita expenditure on legumes varied greatly by state with highest expenditure in Louisiana, South Carolina, Florida, Alabama, Mississippi, and lowest expenditure in Washington, New York, and Wisconsin. There were large regional differences in the most commonly purchased legumes. Of 4,741 adults who participated in the 24-h dietary recall in NHANES, 2017–2018, 20.5% reported eating any legumes in the previous 24 h. Those who consumed legumes were more likely to be Hispanic, with a higher education level, with a larger household size (all P < 0.05), but were not different by age, gender, or income level compared to those who did not consume legumes.Conclusion: Although legumes are inexpensive, healthy, and a sustainable source of protein, per capita legume intake remains low in the US and below US dietary guidelines. Further insight is needed into barriers to legume consumption in the US.

Plasma Metabolomic Signatures of Healthy Dietary Patterns in the Chronic Renal Insufficiency Cohort (CRIC) Study

BackgroundIn individuals with chronic kidney disease (CKD), healthy dietary patterns are inversely associated with CKD progression. Metabolomics, an approach that measures many small molecules in biofluids, can identify biomarkers of healthy dietary patterns. ObjectivesWe aimed to identify known metabolites associated with greater adherence to 4 healthy dietary patterns in CKD patients. MethodsWe examined associations between 486 known plasma metabolites and Healthy Eating Index (HEI)-2015, Alternative Healthy Eating Index (AHEI)-2010, the Dietary Approaches to Stop Hypertension (DASH) diet, and alternate Mediterranean diet (aMED) in 1056 participants (aged 21–74 y at baseline) in the Chronic Renal Insufficiency Cohort (CRIC) Study. Usual dietary intake was assessed using a semiquantitative FFQ. We conducted multivariable linear regression models to study associations between healthy dietary patterns and individual plasma metabolites, adjusting for sociodemographic characteristics, health behaviors, and clinical factors. We used principal component analysis to identify groups of metabolites associated with individual food components within healthy dietary patterns. ResultsAfter Bonferroni correction, we identified 266 statistically significant diet-metabolite associations (HEI: n = 60; AHEI: n = 78; DASH: n = 77; aMED: n = 51); 78 metabolites were associated with >1 dietary pattern. Lipids with a longer acyl chain length and double bonds (unsaturated) were positively associated with all 4 dietary patterns. A metabolite pattern low in saturated diacylglycerols and triacylglycerols, and a pattern high in unsaturated triacylglycerols was positively associated with intake of healthy food components. Plasmalogens were negatively associated with the consumption of nuts and legumes and healthy fat, and positively associated with the intake of red and processed meat. ConclusionsWe identified many metabolites associated with healthy dietary patterns, indicative of food consumption. If replicated, these metabolites may be considered biomarkers of healthy dietary patterns in patients with CKD.

Mobile Device-assisted Dietary Ecological Momentary Assessments for the Evaluation of the Adherence to the Mediterranean Diet in a Continuous Manner.

Mobile device-assisted dietary ecological momentary assessments (EMAs) have emerged as a new tool allowing the evaluation of dietary intake in real time, in a real-world setting and in a continuous manner. They have the potential to minimize recall bias, participant, and investigator burden, and decrease economic and time investment while maximizing ecological validity. We developed a set of EMAs aimed at evaluating continuous adherence to the MedDiet. Four multiple-choice EMAs are sent daily in a randomized manner from a total of eight questions. The EMAs enquire about the consumption of 11 key food groups of the Mediterranean diet in the last 24-48 h in a semi-quantitative way. EMAs capture the daily frequency of consumption of fruits, vegetables, and extra virgin olive oil on different days of the week. Additionally, EMAs capture the weekly frequency of consumption of whole grain products, sugary drinks, nuts, legumes, sweets, fish and seafood, and red and processed meats. A designed scoring system behind the EMAs extracts the percentage of adherence to the MedDiet recommendations and calculates a quality index of the diet every week. Individualized reports are sent periodically to the volunteers highlighting the strengths and weaknesses of their diet. EMAs are also expected to have a behavioral effect, reinforcing the choice of Mediterranean foods.

Association between the socio-economic status of households and a more sustainable diet.

A sustainable diet is an affordable diet with low environmental impact, high food security and sufficient healthiness. The present study aimed to assess the correlation between the socio-economic status of households and a sustainable diet. The food basket and socio-economic data of Iranian households were evaluated during 2016-2018. The households were classified based on the sustainability of their diet by determining the dietary carbon footprint, dietary water footprint, lower dietary costs of the household than the median and a higher dietary quality index than the median. Logistic regression was used with four models to calculate the OR of a more sustainable diet as the dependent variable regarding the different quartiles of socio-economic status (SES) as the independent variable. Iran. Iranian households (n 102 303), nationally representative, were studied. Lower SES was associated with the higher OR of a sustainable diet (OR: 0·90; (95 % CI 0·87, 0·91)). Higher quartiles of SES compared with the lower SES group indicated the higher energy intake and consumption of more dairies, meat, poultry, fish, eggs, legumes, nuts and fruits, as well as the lower intake of bread, cereal, rice and pasta. In countries such as Iran, where nutrition transition occurs rapidly, better economic and social levels in the populations with a higher SES are associated with increased energy intake and higher consumption of animal-based foods, which decreases sustainable diets compared with the groups with a lower SES.

Dietary patterns and blood pressure in Southern Cone of Latin America

Background and aimsin the Southern Cone of Latin America, previous studies have shown that blood hypertension is one of the most significant risk factor for cardiovascular disease, and diet plays a fundamental role. We analyzed the cross-sectional relationship between dietary patterns (DP) and blood pressure values in people involved in the CESCAS I Study. Methods and resultsthe participants (n = 4626) were derived from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). To define DP, a food-frequency questionnaire was applied and principal component analysis was performed. Blood pressure was determined according to standardized guidelines. A multivariate regression model was developed to determine the association between each DP and blood pressure values, according to the quartile (Q) of adherence to DP. Two predominant DP were detected, Prudent (PDP, higher consumption of fruits, vegetables, legumes, whole grains, fish, seafood and nuts) and Western (WDP, higher consumption of red and processed meats, dressings, sweets, snacks and refined grains). A significant inverse association was found between adherence to PDP and systolic and diastolic blood pressure (−1.85 and −1.29 mmHg for Q4 vs Q1, respectively). Adherence to WDP was positively associated with systolic blood pressure (2.09 mmHg for Q4 vs Q1). Conclusionthe WDP detected in the studied population is positively associated with higher levels of blood pressure, while greater adherence to healthy DP has a positive impact on blood pressure.

Dietary changes and food habits: social and clinical determinants in a cohort of women diagnosed with breast cancer in Barcelona (DAMA cohort).

The aim of this study was to analyze the influence of social determinants on changes in dietary habits before and after diagnosis of breast cancer in women (Barcelona, 2003-2013). We performed a cohort study with 2,235 women diagnosed with breast cancer. The information was obtained from an ad hoc questionnaire based on recommendations from the Spanish Society of Community Nutrition. We conducted a descriptive bivariate analysis and fit logistic regression models. The dependent variable was the change in dietary habits (food groups) and the independent variables were a selection of social and clinical variables (age, social class, cohabitation, years since diagnosis, history of replaces, and treatment with chemotherapy). While 5.8% of women followed a healthy diet (consumption of vegetables, fruits, farinaceous, lean meat, and seafood) before diagnosis, 9.5% did so after diagnosis. We observed statistically significant changes in consumption of all food groups (p < 0.001) after diagnosis. The greatest change in consumption patterns was observed in women aged < 50years and those from non-manual classes (high classes) [e.g., legume consumption: OR<50years/>65years = 2.9 (95% CI 1.78-4.81); ORnon-manual/manual = 2.5 (95% CI 1.38-4.36)]. The occurrence of relapses and chemotherapy was associated with greater changes in dietary habits. Women with breast cancer change their eating habits after diagnosis, and these changes are conditioned by social and clinical determinants.

Maternal lifestyle and nutritional habits are associated with oocyte quality and ICSI clinical outcomes

Research questionDo maternal lifestyle factors influence the incidence of oocyte dimorphisms and outcomes of intracytoplasmic sperm injection (ICSI) cycles? DesignA total of 752 female patients undergoing an ICSI cycle at a private university-affiliated IVF centre from January 2015 to December 2019 were included in this historical cohort study. Before starting ovarian stimulation, participants completed a questionnaire on cigarette smoking habits, consumption of alcoholic beverages, refined sugar, artificial sweeteners, soft drinks, fruits, legumes and vegetables, milk and dairy, and meat, as well as exercise frequency over the past 6 months. Oocyte morphology was evaluated before ICSI. The influence of maternal lifestyle factors on the incidence of oocyte dimorphisms and ICSI outcomes was evaluated by multivariate general linear models and generalized linear models, adjusted for potential confounders. The main outcome measures were the incidence of oocyte dimorphisms per cycle and clinical outcomes. ResultsLifestyle factors and nutritional habits such as cigarette smoking, and the consumption of alcohol, refined sugar and artificial sweeteners, were positively associated with incidence of several oocyte dimorphisms and negatively associated with the response to ovarian stimulation and embryo development. Negative relationships were also observed between these habits and clinical outcomes, apart from miscarriage rate, in which positive relationships were observed. Significant negative dose-dependent relationships between these habits and implantation rates were noted (P < 0.001). Alcoholic beverage consumption also showed inverse dose-dependent relationships with clinical pregnancy and live birth rates. Live birth rate was also negatively associated with cigarette smoking, in a dose-dependent manner. ConclusionsPoor maternal habits were associated with reduced oocyte quality and ICSI outcomes in this study. Many of these associations were shown to be dose-dependent.

The food choice determinants and adherence to Mediterranean diet in Iranian adults before and during COVID-19 lockdown: population-based study

PurposeDuring the Coronavirus Disease 2019 (COVID-19) pandemic, some changes in dietary intake were observed.
