Abstract
BACKGROUND Follow-up of COVID-19 recovered patients to discover important adverse effects on other organs is required. The psychological health of COVID-19 patients may be affected after recovery. AIM We aimed to evaluate the association between adherence to the Nordic diet (ND) and psychological symptoms caused by COVID-19 after recovery. METHOD Dietary data on 246 qualified adults (123 cases and 123 controls). The dietary intake in this case-control study was calculated by a reliable and valid food frequency questionnaire (FFQ). Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Short-Form Health Survey (SF-36) were used to analyze participant's anxiety, stress, depression, sleep quality, insomnia, and quality of life of participants. RESULTS There was a significant inverse relationship between total anxiety, stress, and depression scores and the intake of whole grains (P < 0.05). Furthermore, there was a significant inverse association between depression and fruit intake (P < 0.05). A significant negative correlation was found between insomnia and sleep quality and the intake of root vegetables (P < 0.05). In the multinomial-regression model, a significant association between the Nordic diet and anxiety, stress, and depression was found only in the case group (OR = 0.719, 95% CI 0.563-0.918, p-value = 0.008; OR = 0.755, 95% CI 0.609-0.934, P-value = 0.010, and, OR = 0.759, 95% CI 0.602-0.956, P-value = 0.019 respectively). CONCLUSION Adherence to the Nordic diet might reduce anxiety, stress, and depression in recovered COVID-19 patients.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of death in women globally. Recent studies have reported that the minor allele (C allele) for melanocortin 4 receptor (MC4R) rs17782313 may be related to the incidence of obesity and the risk of CVD. Therefore, the present study aimed to investigate the interactions between the modified Nordic-style diet score (MND) and MC4R gene variant on markers of CVD. METHODS The current cross-sectional study was conducted on 282 Iranian women, aged 18-48 years, with a body mass index (BMI) ≥ 25. MND score was assessed using a 147 items food frequency questionnaire (FFQ). Genotyping of the MC4R (rs17782313) was conducted by the PCR method. The anthropometric measurements and serum profiles were assessed by standard protocols. RESULTS The means and standard deviation (SD) of age, weight, and BMI of individuals were 36.67 ± 9.10 years, 81.29 ± 12.43 kg, and 31.26 ± 4.29 kg/m2, respectively. The overall prevalence of rs17782313 genotypes was 30.1%, 24.8%, and 45.1% for TT, TC, and CC, respectively. Our results showed significant negative interactions between high MND score and rs17782313 SNP in terms of visceral fat level (VFL) (β: -10.84, 95% CI: -20.64 to -1.04, P = 0.03) and total cholesterol (β: -24.24, 95% CI: -49.87 to 1.38, P = 0.06) in the crude model. After adjusting confounders, the interaction between high MND scores and VFL remained significant. CONCLUSION In conclusion, the results of the present study suggest that diet, gene variants, and their interaction should be considered in metabolic disease risk assessment. Further studies are needed to confirm these data and better elucidate the interaction.

Abstract
OBJECTIVE Previous studies have shown an association between diet quality and sleep quality. The objective of this study was to investigate the association between modified Nordic diet with sleep quality and circadian rhythm in overweight and obese woman. METHODS We enrolled 399 overweight and obese women (body mass index (BMI): 25-40 kg/m2), aged 18-48 years, in this cross-sectional study. For each participant, anthropometric measurements, biochemical tests, and food intake were evaluated. Sleep quality and circadian rhythm was measured by Pittsburgh Sleep Quality Index (PSQI) and morning-evening questionnaire (MEQ) questionnaire. Modified Nordic diet score was measured using a validated 147-item food frequency questionnaire (FFQ). RESULTS Overall, 51.7% of the subjects were good sleepers (the Pittsburgh Sleep Quality Index (PSQI) < 5) while 48.3% were poor sleepers (PSQI ≥ 5). Moreover, participants were divided into five groups of MEQ, namely, completely morning 8 (2.4%), rarely morning 82 (24.8%), normal 196 (59.2%), rarely evening 43 (13%), and completely evening 2 (0.6%). After controlling for confounders, there was a significant association between poor sleep quality and the modified Nordic diet (OR = 0.80, %95 CI = 0.66-0.98, P = 0.01). Moreover, a significant positive association was observed between the completely morning and modified Nordic diet (OR = 1.80, %95 CI = 0.54-6.00, P = 0.03), in addition to a significant inverse association between the completely evening type and modified Nordic diet (OR = 0.16, %95 CI = 0.002-5.41, P = 0.02). CONCLUSIONS The present study indicated that higher adherence to a modified Nordic diet reduces poor sleep quality. Also, the completely morning type was associated with higher adherence to a modified Nordic diet, and completely evening type was associated with lower adherence to a modified Nordic diet. LEVELS OF EVIDENCE Level IV, evidence obtained from multiple time series analysis.

Effects of changing from a diet with saturated fat to a diet with n-6 polyunsaturated fat on the serum metabolome in relation to cardiovascular disease risk factors. Eur J Nutr 2022; 61:2079-2089. [PMID: 34999928 PMCID: PMC9106625 DOI: 10.1007/s00394-021-02796-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 12/21/2021] [Indexed: 11/27/2022]
Abstract
Purpose Replacing saturated fatty acids (SFA) with polyunsaturated fatty acids (PUFA) is associated with a reduced risk of cardiovascular disease. Yet, the changes in the serum metabolome after this replacement is not well known. Therefore, the present study aims to identify the metabolites differentiating diets where six energy percentage SFA is replaced with PUFA and to elucidate the association of dietary metabolites with cardiometabolic risk markers. Methods In an 8-week, double-blind, randomized, controlled trial, 99 moderately hyper-cholesterolemic adults (25–70 years) were assigned to a control diet (C-diet) or an experimental diet (Ex-diet). Both groups received commercially available food items with different fatty acid compositions. In the Ex-diet group, products were given where SFA was replaced mostly with n-6 PUFA. Fasting serum samples were analysed by untargeted ultra-performance liquid chromatography high-resolution mass spectrometry (UPLC-HRMS). Pre-processed data were analysed by double cross-validated Partial Least-Squares Discriminant Analysis (PLS-DA) to detect features differentiating the two diet groups. Results PLS-DA differentiated the metabolic profiles of the Ex-diet and the C-diet groups with an area under the curve of 0.83. The Ex-diet group showed higher levels of unsaturated phosphatidylcholine plasmalogens, an unsaturated acylcarnitine, and a secondary bile acid. The C-diet group was characterized by odd-numbered phospholipids and a saturated acylcarnitine. The Principal Component analysis scores of the serum metabolic profiles characterizing the diets were significantly associated with low-density lipoprotein cholesterol, total cholesterol, and triglyceride levels but not with glycaemia. Conclusion The serum metabolic profiles confirmed the compliance of the participants based on their diet-specific metabolome after replacing SFA with mostly n-6 PUFA. The participants' metabolic profiles in response to the change in diet were associated with cardiovascular disease risk markers. This study was registered at clinicaltrials.gov as NCT 01679496 on September 6th 2012.

Abstract
PURPOSE Obesity as a worldwide phenomenon is a multifactorial condition. Healthy diets have effect on obesity-related factors like resting metabolic rate (RMR). In the present study, we investigate the association between adherence to modified Nordic diet and RMR among overweight and obese participants. METHODS We enrolled 404 overweight and obese (BMI ≥ 25 kg/m2 ) women aged 18-48 years in this cross-sectional study. For each participant, anthropometrics measurements, biochemical tests and blood pressure were evaluated. RMR was measured by indirect calorimetry. RMR/kg was also measured. Modified Nordic diet score was measured using a validated 147-item food frequency questionnaire (FFQ). RESULTS Among all participants, the mean and standard deviation (SD) for age and body mass index (BMI) were 36.67 years (SD = 9.10) and 31.26 kg/m2 (SD = 4.29), respectively. There was a significant association between RMR/kg status and age, body mass index (BMI), RMR (P < .001), respiratory quotient (RQ), fat percentage (P = .01), systolic blood pressure (SBP) (P = .03) and diastolic blood pressure (DBP) (P = .04), after adjustment for age, BMI, energy intake and physical activity. Participants with the highest adherence to modified Nordic diet had lower odds of hypometabolic status after adjusting for confounders and it was significant (odds ratio (OR) = 3.15, 95% CI = 0.97-10.15, P = .05). CONCLUSIONS The present results indicate that adherence to modified Nordic diet is associated with lower odds of hypometabolic status in overweight and obese women. However, more studies are needed to confirm our findings.

Abstract
AIMS Several health benefits are contributed to extra virgin olive oil (EVOO). The polyphenol fraction of EVOO may be responsible for its cardioprotective impacts. This systematic review and meta-analysis aimed to investigate the effect of EVOO intake on glycemic parameters. Electronic literature searched through 1 September 2020 across MEDLINE/PubMed, Web of Science, and SCOPUS databases to find all clinical trials that reported the effect of EVOO intake on glycemic parameters [FBS(fasting blood glucose), insulin, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) and HbA1c (glycated hemoglobin A1c)] vs. control. DATA SYNTHESIS We pooled standardized mean differences (SMD) and 95% confidence intervals (CIs) from randomized clinical trials (RCTs) using random-effects models. Heterogeneity was assessed by Cochran Q-statistic and quantified (I2). We found 13 related trials comprising a total of 633 subjects. In pooled analysis, EVOO intake had no effect on FBS (SMD: -0.07; 95% CI: -0.20, 0.07; I2 = 0.0%), insulin (SMD: -0.32; 95% CI: -0.70, 0.06; I2 = 38.0%), and HOMA-IR (SMD: -0.32; 95% CI: -0.75, 0.10; I2 = 51.0%). However, a decreasing trend was observed in these effects. Subgroup analysis based on age, health status, dose, and EVOO intake duration also did not significantly change results. CONCLUSION Although EVOO seems a promising hypoglycemic effects, we did not find any significant evidence that EVOO consumption impacts glucose homeostasis. Furthermore, well-designed RCTs with longer durations are still needed to evaluate the EVOO's efficacy on glycemic parameters.

Abstract
BACKGROUND Nutrition plays a pivotal role in the prevention and treatment of endocrine disorders. The aim of this study was to provide a window in order to display the 25-year activities of Endocrinology & Metabolism Research Institute (EMRI), and the gaps and future plans in the field of nutrition and endocrine disorders. METHODS To collect papers affiliated to the EMRI in field of nutrition from the inception to December 1st 2019, the electronic databases including PubMed/Medline, Web of Science, and Scopus were searched. Publications in English and Persian languages were included. Scientific Landscapes (VOS viewer) software version 1.6.13 was used to provide bibliometric maps. RESULTS Of 4082 studies identified in the initial search, 319 relevant papers were included. They contributed systematic review and meta-analysis/review (n = 76), clinical trials (n = 58), cross-sectional (n = 171), case-control studies (n = 11), and animal studies (n = 3). Accordingly, most nutrition studies were dedicated to the level of evidence III (cross-sectional studies: 53.60%) followed by systematic review studies (23.82%) with the level of evidence I. There was also an increasing trend in the nutrition studies through years, with a peak in 2019. CONCLUSION An increasing trend in the publications related to nutrition science is observed at EMRI. However, nutrition research and publications can grow further through expanding collaborations with other fields related to endocrine. Given nutritional assessments in national projects and focusing on the identification of preventive nutritional strategies, considering the situations of our society can be helpful to make nutritional findings more practical.

Abstract
BACKGROUND There has been a rapid increase in the prevalence of psychiatric and psychological disease, and this has attracted interest in identifying modifiable lifestyle factors that may affect an individual's mood. Diet is one potential lifestyle factor that may affect psychological function. AIM This study aimed to investigate the relationship between adherence to the health-promoting Nordic diet (ND) with neuropsychological function in young women. METHODS The study comprised 181 female students aged between 18 and 25 years. Psychological function was evaluated using a series of standardized questionnaires, including the Cognitive Ability Questionnaire, Depression Anxiety Stress Scale, Insomnia Severity Index, Epworth Sleep Scale and Quality of Life Questionnaire. A validated food frequency questionnaire, which included 65 types of foods, was used to evaluate the amount of different foods consumed. RESULTS Evaluation of the dietary composition of the participants showed that the rate of adherence to the ND was positively associated with total energy, carbohydrates, protein, fibre, iron, magnesium, potassium, zinc, folate, phosphorus, vitamin C, thiamine, riboflavin, niacin, vitamins B6 and B12, carotene, whole grain, legumes, cabbage/vegetables, vegetables and fruit (p<0.05). Linear regression showed cabbage/vegetable consumption was inversely related to scores of stress (β=-0.04; p=0.038) and anxiety (β=-0.02; p=0.049) and directly associated with the quality-of-life score (0.02; p=0.036). CONCLUSIONS Adherence to a ND with a high intake of cabbage/vegetables was inversely associated with stress and anxiety scores and directly associated with health-related quality of life.

Influence of magnitude of weight loss on Adipo/lep ratio in adolescents with obesity undergoing multicomponent therapy. Cytokine 2020; 131:155111. [PMID: 32371378 DOI: 10.1016/j.cyto.2020.155111] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 04/16/2020] [Accepted: 04/24/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIMS The expansion of adipose tissue increases leptin secretion associated with a reduction of adiponectin concentration, which negatively affects health of adolescents with obesity. This study aims to investigate the effects of non-intensive interdisciplinary therapy on cardiometabolic parameters including leptin, adiponectin and adiponectin/leptin ratio as a dependent manner on its magnitude of weight loss reduction. METHODS AND RESULTS Thirty-eight adolescents (14-19 y.o) were enrolled in an interdisciplinary therapy for 20 weeks. Body composition, biochemical parameters, leptin and adiponectin were measured at baseline and after therapy. The adolescents were divided into two groups according to the magnitude of total weight loss, less than 5% (<5%-n = 18) or greater than or equal to 5% (≥5%-n = 20). Leptin decreased in whole group after therapy, while adiponectin, and adiponectin/leptin ratio increased. Additionally, body composition was improved. Only the group who lost ≥5% of body weight could reduce the inflammatory state. CONCLUSION The interdisciplinary therapy contributes to improve cardiometabolic parameters that could be involved on inflammation in adolescents with obesity, this improvement occurred mainly when the weight loss is ≥5% of body weight. It could be a target for control the inflammatory process related to obesity in adolescents.

Abstract
Healthy dietary habits are the cornerstone of cardiovascular disease (CVD) prevention. Numerous researchers have developed diet quality indices to help evaluate and compare diet quality across and within various populations. The availability of these new indices raises questions regarding the best selection relevant to a given population. In this perspective, we critically evaluate a priori-defined dietary indices commonly applied in epidemiological studies of CVD risk and mortality. A systematic literature search identified 59 observational studies that applied a priori-defined diet quality indices to CVD risk factors and/or CVD incidence and/or CVD mortality. Among 31 different indices, these scores were categorized as follows: 1) those based on country-specific dietary patterns, 2) those adapted from distinct dietary guidelines, and 3) novel scores specific to key diet-related factors associated with CVD risk. The strengths and limitations of these indices are described according to index components, calculation methods, and the application of these indices to different population groups. Also, the importance of identifying methodological challenges faced by researchers when applying an index are considered, such as selection and weighting of food groups within a score, since food groups are not necessarily equivalent in their associations with CVD. The lack of absolute cutoff values, emphasis on increasing healthy food without limiting unhealthy food intake, and absence of validation of scores with biomarkers or other objective diet assessment methods further complicate decisions regarding the best indices to use. Future research should address these limitations, consider cross-cultural and other differences between population groups, and identify translational challenges inherent in attempting to apply a relevant diet quality index for use in CVD prevention at a population level.

Abstract
BACKGROUND Diabetes is a common chronic disease with many complications and is associated with the development of cardiovascular diseases (CVD). The present study aimed to investigate the association of diet quality indices and CVD risk factors among diabetic women. This cross-sectional study was conducted in 230 Tehrani women with type 2 diabetes. A validated and reliable food frequency questionnaire was completed to assess the dietary intake. Diet quality indices were considered with respect to adherence to the Healthy Eating Index-2010 (HEI-2010) and Diet Quality Index-International (DQI-I). Anthropometric measurements, blood pressure and biochemical tests were assessed. CVD risk factors were evaluated according to the adult treatment panel III. RESULTS Patients who were in the top tertile of the DQI consumed less fat, saturated fatty acids and sodium, as well as more protein, fiber, iron and calcium (P < 0.05). Participants who were in the top tertile of diet quality indices consumed less processed and organ meat and more fruits, and vegetables. Patients in the highest tertile of HEI had lower fasting blood sugar levels (148.92 ± 6.05 mg dL-1 versus 171.30 ± 5.79 mg dL-1 , P = 0.021). There was no significant association between DQI-I, HEI and other CVD risk factors. CONCLUSION There was no association between diet quality indices and CVD risk factors among diabetic patients. © 2019 Society of Chemical Industry.

Abstract
Introduction: Limited studies are available regarding the relationship between Food Quality Score (FQS) and cardiovascular disease (CVD) risk factors. Thus, this study was aimed to investigate the association of FQS with CVD risk factors in women.
Methods: This cross-sectional study was carried out among 368 women aged 20-50 years who randomly selected from health centers across Tehran, Iran. Dietary intake was collected using a reliable and validated food frequency questionnaire (FFQ). The FQS includes vegetables, fruits, whole grains, yogurt, nuts and legumes, coffee, refined grains, desserts and ice cream, sugar-sweetened beverages, red meats, fried food consumed outside the home, processed meats, potato and potato chips. Standard methods were used to assess blood pressure, biochemical and anthropometric measures. Multivariate logistic regression was used to examine the association between FQS and CVD risk factors.
Results: Participant mean age and body mass index (BMI) were 30.7 ± 6.9 years and 24.3 ± 4.0 kg/m2, respectively. After taking potential confounders into account, FQS had no significant association with risk of overweight and obesity [Odds ratio (OR): 1.1, 95% confidence interval (CI): 0.68, 1.8; P = 0.683], diabetes (OR: 0.62, 95% CI: 0.22, 1.74; P = 0.374), metabolic syndrome (OR: 0.36, 95% CI: 0.10, 1.32; P = 0.127), hypercholesterolemia (OR: 0.54, 95% CI: 0.29, 1.01; P= 0.051), or hypertriglyceridemia (OR: 1.63, 95% CI: 0.71, 3.70; P = 0.244).
Conclusion: The results showed that FQS was not significantly associated with CVD risk factors among women. Prospective cohort studies are warranted to confirm our findings.
