Background and Objectives: In Iranian Islamic culture, one of the most important duties of mothers is to take care of their children. Caring for a child with a mental or physical disability is fraught with challenges. Therefore, the purpose of this study was to review the lived experiences of mothers with children with physical and mental disabilities. Materials and Methods: This study was performed by a qualitative approach and document analysis using meta-synthesis method to examine 13 articles related to the seven-step method of Sandlowski and Barros. The stages of this research included preparing the research question, reviewing the texts systematically, searching and selecting appropriate texts, extracting textual information, analyzing and combining qualitative findings, quality control, and presenting the findings. Results: Dimensions and categories included individual dimensions (personal education and knowledge, emotions, spirituality, defense mechanisms, personal life) and social dimensions (social stigmas, social supports). Conclusions: The findings of the present study revealed that mothers with disabled children experience many painful experiences and psychosocial concerns about caring for their disabled child. These findings highlight the need for specialized support for mothers during the first years of a disabled child's birth and beyond, and encourage readers and professionals to make each of these categories a potential therapeutic goal, and to strengthen mothers' strengths in resilience, and in this way prevent the damage they face.

Introduction: Spiritual intelligence gives an individual a broad perspective regarding her life, religion, and all their experiences. It enables them to reanalyze life experiences and gain a deeper understanding. The present study was an attempt to examine the relationship between spiritual intelligence and commitment to religious beliefs in civil servants. Methods: It was a correlational study, with the research population consisting the staff of Defense Ministry thoughout Iran in 2011. The sample included 10,389 individuals selected using random cluster sampling. Data collection was done using a researcher-made questionnaire to measure participants' practical commitment to religious beliefs and another questionnaire to examine their spiritual intelligence. Data analysis was done using Pearson correlation coefficient and a multiple regression test. Results: A significant relationship was observed between commitment to religious beliefs and participants' spiritual intelligence in the subscales of Self-awareness, Spiritual experience, Patience, and Generosity. The relationship between the total score of spiritual intelligence and commitment to religious beliefs was found to be 0.74. The results of the regression analysis showed that 55 percent of the variance in spiritual intelligence could be explained by participants' commitment to religious beliefs. Conclusion: The direct relationship between the two variables shows that employees with higher spiritual intelligence are more practically committed to religious beliefs. [ABSTRACT FROM AUTHOR]

Abstract Objectives This study aims to find whether breakfast consumption is associated with human mental health. Study design This cross-sectional study was conducted to investigate the association between breakfast consumption and psychological disorders, including depression and anxiety, among Iranian adults. Methods This cross-sectional study was conducted on 4378 general public adults in Isfahan, Iran. Breakfast consumption was assessed using a validated detailed dietary habits' questionnaire. Depression and anxiety were screened using an Iranian validated Hospital Anxiety and Depression Scale questionnaire. Psychological distress was examined by means of Iranian validated version of General Health Questionnaire (GHQ-12 items). Depression, anxiety, and psychological distress were defined based on standard criteria. Results Overall, 13.95% (n = 611) of study participants had anxiety, 28.62% (n = 1253) were depressive, and 23.18% (n = 1015) had psychological distress. After controlling for potential confounding variables, participants with every day breakfast consumption had lower odds for depression (odds ratio [OR]: 0.49, 95% confidence interval [95% CI]: 0.36–0.66) compared with those with the least frequent intake of breakfast, even after further adjustment for body mass index [BMI] (OR: 0.47, 95% CI: 0.34–0.63). Frequent breakfast consumption was inversely associated with anxiety before (OR: 0.53, 95% CI: 0.37–0.76, P < 0.001) and after controlling for BMI (OR: 0.52, 95% CI: 0.36–0.75, P < 0.001). The same findings were obtained for psychological distress (OR: 0.46, 95% CI: 0.33–0.62, P < 0.001). Conclusion We found an inverse association between breakfast consumption and depression, anxiety, and psychological distress among Iranian adults. Further prospective studies are needed to confirm these findings. Highlights • There was an inverse association between breakfast consumption and depression, anxiety, and psychological distress among Iranian adults. • The prevalence of depression among breakfast skippers was 45.7% and among those with regular breakfast intake was 25.0%. • The prevalence of anxiety among breakfast skippers was 23.8% and among those with regular breakfast intake was 11.7%. • Psychological distress was highly prevalent among breakfast skippers (39.3%) than those with regular breakfast intake (19.6%).

Anxiety disorders occur in all human societies ; yet there are cross- cultural variations in the symptomatology, prevalence, the etiologically contributing bio-psycho-social factors and the social responses to the symptoms and their management. Iran has a heterogeneous population with numerous subcultures bounded closely to each other through the common history, language, Old Persian culture and the similarities in their impressing experiences as a nation. In the format of a narrative review article, here we intend to induce a minimal insight into a few areas of particularity of anxiety disorders in Iranian culture. We will focus on the examples of socio-cultural factors affecting the source of distress, helpseeking behaviors, symptom presentation and treatment of these disorders in Iran.

Introduction: Whereas (GCC)-repeats are overrepresented in genic regions, and mutation hotspots, they are largely unexplored with regard to their link with natural selection. Across numerous primate species and tissues, SMAD9 (SMAD Family Member 9) reaches highest level of expression in the human brain. This gene contains a (GCC)-repeat in the interval between + 1 and + 60 of the transcription start site, which is in the high-ranking (GCC)-repeats with respect to length., Methods: Here we sequenced this (GCC)-repeat in 396 Iranian individuals, consisting of late-onset neurocognitive disorder (NCD) (N = 181) and controls (N = 215)., Results: We detected two predominantly abundant alleles of 7 and 9 repeats, forming 96.2% of the allele pool. The (GCC)7/(GCC)9 ratio was in the reverse order in the NCD group versus controls (p = 0.005), resulting from excess of (GCC)7 in the NCD group (p = 0.003) and (GCC)9 in the controls (p = 0.01). Five genotypes, predominantly consisting of (GCC)7 and lacking (GCC)9 were detected in the NCD group only (p = 0.008). The patients harboring those genotypes received the diagnoses of Alzheimer's disease (AD) and vascular dementia (VD). Five genotypes consisting of (GCC)9 and lacking (GCC)7 were detected in the control group only (p = 0.002). The group-specific genotypes formed approximately 4% of the genotype pool in the human samples studied., Conclusion: We propose natural selection and a novel locus for late-onset AD and VD at the SMAD9 (GCC)-repeat in humans., (© 2024.

Introduction: There are different types of COVID-19 vaccines approved worldwide. Since no national studies focus on vaccine-related adverse reactions and breakthrough cases, this study aimed to investigate the rate of adverse events and COVID-19 infection in medical students in Iran., Methods: This retrospective cohort study included Iranian medical students who received two doses of COVID-19 vaccines. The medical team gathered the demographic characteristics, comorbidities, type of vaccine, adverse events following vaccination, and history of COVID-19 infection data through a phone interview. The frequency of adverse events and breakthrough infection was stratified by vaccine type (ChAdOx1-S, Gam-COVID-Vac, and BIBP-CorV)., Results: A total of 3,591 medical students enrolled in this study, of which 57.02% were females, with a mean age of 23.31 + 4.87. A PCR-confirmed and suspicious-for-COVID-19 breakthrough infection rate of 4.51 and 7.02% was detected, respectively. There was no significant relation between breakthrough infection and gender, BMI, blood groups, and comorbidities. However, there was a significant difference in breakthrough infection rate among different types of vaccines ( p = 0.001) and history of COVID-19 infection ( p = 0.001). A total of 16 participants were hospitalized due to COVID-19 infection after vaccination for reasons such as dyspnea, abnormal imaging, or decreased oxygen saturation. No severe infection or death was observed in the studied population., Conclusion: Vaccination prevented severe COVID-19 infection, although a high breakthrough infection rate was evident among Iranian medical students during the Delta variant's peak. Vaccine effectiveness may be fragile during emerging new variants and in high-exposure settings. Moreover, adverse events are rare, and the benefits of vaccination outweigh the side effects. However, many limitations challenged this study, and the results should be cautious., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Allahgholipour, Safavi-Naini, Shekarriz Foomany, Eskandari, Nazari Rostami, Honarvar, Mohammadi, Khalili, Ilaghi, Afshar, Amini Baghbadorani, Moghimi, Chamani Goorabi, Mehrparvar, Safari, Nakhli, Mahmoudabadi, Seifadini, Sheikhansari, Khojastehfar, Mahdavi, Mohammadi, Ashrafi Barzideh, Akbarzadeh, Delavarpour Moghadam, Tavakoli Pirzaman, Barary and Emamhadi.)

Findings of earlier investigations on association between dietary riboflavin intake and psychological disorders are contradictory. Therefore, the relation between dietary riboflavin intake and depression, anxiety, and psychological distress was assessed in Iranian adults. In this cross-sectional study, dietary intakes of 3362 middle-aged adults were collected using a validated dish-based food frequency questionnaire. Daily intake of riboflavin for each participant was calculated by summing up the amount of riboflavin contents of all foods and dishes. Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), as validated questionnaires among Iranians, have been applied to assess depression, anxiety, and psychological distress. After considering potential confounders, adults in the top energy-adjusted quartile of riboflavin intake, compared to the bottom quartile, had decreased odds of depression (OR = 0.66; 95%CI 0.49, 0.88), anxiety (OR = 0.64; 95%CI 0.44, 0.94) and high psychological distress (OR = 0.65; 95%CI 0.48, 0.89). Stratified analysis by sex revealed that men in the forth quartile of riboflavin intake, compared with those in the first quartile, had respectively 51 and 55% lower odds of depression (OR = 0.49; 95%CI 0.29, 0.83) and anxiety (OR = 0.45; 95%CI 0.21, 0.95). In women, riboflavin intake was significantly associated with lower odds of psychological distress (OR = 0.67; 95%CI 0.46, 0.98). An inverse relation was observed between dietary riboflavin intake and chance of psychological disorders in Iranian adults. High intake of riboflavin decreased the chance of depression and anxiety in men and high psychological distress in women. More prospective studies are needed to confirm these findings., (© 2023.

The human SBF1 (SET binding factor 1) gene, alternatively known as MTMR5, is predominantly expressed in the brain, and its epigenetic dysregulation is linked to late-onset neurocognitive disorders (NCDs), such as Alzheimer's disease. This gene contains a (GCC)-repeat at the interval between + 1 and + 60 of the transcription start site (SBF1-202 ENST00000380817.8). We sequenced the SBF1 (GCC)-repeat in a sample of 542 Iranian individuals, consisting of late-onset NCDs (N = 260) and controls (N = 282). While multiple alleles were detected at this locus, the 8 and 9 repeats were predominantly abundant, forming &gt; 95% of the allele pool across the two groups. Among a number of anomalies, the allele distribution was significantly different in the NCD group versus controls (Fisher's exact p = 0.006), primarily as a result of enrichment of the 8-repeat in the former. The genotype distribution departed from the Hardy-Weinberg principle in both groups (p &lt; 0.001), and was significantly different between the two groups (Fisher's exact p = 0.001). We detected significantly low frequency of the 8/9 genotype in both groups, higher frequency of this genotype in the NCD group, and reverse order of 8/8 versus 9/9 genotypes in the NCD group versus controls. Biased heterozygous/heterozygous ratios were also detected for the 6/8 versus 6/9 genotypes (in favor of 6/8) across the human samples studied (Fisher's exact p = 0.0001). Bioinformatics studies revealed that the number of (GCC)-repeats may change the RNA secondary structure and interaction sites at least across human exon 1. This STR was specifically expanded beyond 2-repeats in primates. In conclusion, we report indication of a novel biological phenomenon, in which there is selection against certain heterozygous genotypes at a STR locus in human. We also report different allele and genotype distribution at this STR locus in late-onset NCD versus controls. In view of the location of this STR in the 5' untranslated region, RNA/RNA or RNA/DNA heterodimer formation of the involved genotypes and alternative RNA processing and/or translation should be considered., (© 2022.

Background/aims: Accumulating evidence based on a few studies suggests a relationship between depression and functional constipation. This study examined whether depression is associated with a higher risk of functional constipation and whether it is gender specific., Methods: This cross-sectional study was carried out on 3,362 adults aged 18-55 years. In this study, functional gastrointestinal symptoms were determined using an Iranian reliable and valid version of the modified Rome III questionnaire. The Iranian validated version of the hospital anxiety and depression scale was used to evaluate the psychological health. Scores of eight or more on the depression subscale in the questionnaire were considered the presence of depression. Simple and multiple binary logistic regression were used for data analysis., Results: The mean±SD age of participants was 36.29±7.87 years, and 58.5% were female. The prevalence of depression and constipation in the study sample was 28.6% and 23.9%, respectively. In the full adjusted model, in the total sample, depressed people showed a significantly higher risk of constipation; adjusted OR (AOR), 1.69 (95% CI, 1.37-2.09). Although a significant association was observed between depression and constipation in both genders, the association was stronger in men than women (AOR, 2.28; 95% CI, 1.50, 3.63 vs. AOR, 1.55; 95% CI, 1.21, 1.99)., Conclusions: These study findings showed that depressed people are at a significantly higher risk of being affected by constipation. The current study findings justify the importance of mental health evaluations in all patients with functional gastrointestinal disorders, particularly among constipated individuals.

Previous investigations have mostly studied an individual methyl donor nutrient in relation to psychological disorders and the findings were inconsistent. We investigated the association of methyl donor micronutrients (folate, B 6 , B 12 , choline, betaine and methionine) with psychological disorders in Iranian adults. In this cross-sectional study, dietary intakes of 3299 adults were collected using a validated food frequency questionnaire. Methyl donor micronutrient score (MDMS) was calculated based on energy-adjusted deciles of each nutrient. Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), validated for Iranians, have been applied to assess depression, anxiety and psychological distress. Participants had a mean age of 36·3 ± 7·9 years, of whom 58·5 % were women. After considering potential confounders, adults in the top quartile of MDMS, compared to the bottom one, had decreased odds of anxiety (OR: 0·53, 95 % CI: 0·37, 0·75), depression (OR: 0·75, 95 % CI: 0·58, 0·97) and psychological distress (OR: 0·61, 95 % CI: 0·46, 0·80). Among women, the top quartile of MDMS was protectively associated with anxiety (OR: 0·60, 95 % CI: 0·40, 0·90), depression (OR: 0·68, 95 % CI: 0·50, 0·93) and psychological distress (OR: 0·53, 95 % CI: 0·38, 0·74). Overweight and obese subjects in the highest quartile of MDMS had a 67 %, 35 % and 53 % lower odds of anxiety (95 % CI: 0·20, 0·56), depression (95 % CI: 0·44, 0·94) and psychological distress (95 % CI: 0·31, 0·70), respectively. We found that high consumption of methyl donor micronutrients was related to a reduced odds of psychological disorders, especially in women and overweight or obese individuals.

Based on the results of a needs analysis program, already conducted in a parallel study, a need-based teacher professional development program (TPDP) was designed and implemented, which was supported by peer coaching (as a follow-up strategy) and evaluation to address the current needs of Iranian English teachers serving at public junior high schools and to offer suggestions for policy and practice. The effectiveness of the program was evaluated through various data collection methods (i.e. focus group discussions, questionnaires, and semi-structured interviews) taking into account the perspectives of teachers, supervisors, and teacher educators. Besides, the possible effects of the program on students' foreign language achievement were investigated. The results of evaluations indicated that although needs-based peer-coached TPDPs were more likely to consolidate English teachers' knowledge, improve their teaching practices, and promote students' academic achievement, teacher education policy-makers and professional development (PD) designers/providers in Iran still followed more traditional approaches, keeping teachers in isolation and not allowing the exchange of ideas to take place among them. The results provide insights for and offer practical suggestions to education policy-makers and TPDP designers/providers in many developing countries including Iran to avoid future failures and discouraging outcomes due to the provision of improper TPDPs that do not take into account the actual professional needs of the teachers., (Copyright © 2022 Elsevier Ltd.

Background: Plant-based dietary pattern, a new scoring system, has had a favorable relationship with the risk of chronic diseases, however, the associations with mental health are long disputed. Thus, we examined the association between an overall plant-based diet (PDI), healthy plant-based diet (hPDI), and unhealthy plant-based diet (uPDI) and psychological disorders in adult Iranian patients., Methods: In this large cross-sectional study, 3,362 Iranian men and women were recruited. Dietary data were gathered using a validated and reliable Willett format food frequency questionnaire (FFQ). Plant-based dietary pattern scores were calculated based on the method of Satija et al. Psychological profile assessment was done using the validated hospital anxiety and depression scale (HADS) and the general health questionnaire (GHQ)., Results: A total number of 943, 448, and 760 participants who suffered from depression, anxiety, and psychological distress, respectively, were identified. In the multivariable-adjusted analysis, participants in the highest category of PDI and hPDI scores had lower odds of having depression and anxiety than those in the lowest category. This association was also found between hPDI and psychological distress (OR: 0.51, 95% CI: 0.38-0.68). In contrast, higher scores of uPDI was associated with increased odds of anxiety (OR: 1.60, 95% CI: 1.06-2.42) and psychological distress (OR: 1.38, 95% CI: 1.01-1.90)., Limitation: The cross-sectional study design., Conclusion: Our results indicated that greater adherence to the overall plant-based diet and healthy plant-based diet was inversely associated with psychological disorders, while following unhealthy plant-based diet increased the risk of anxiety and psychological distress., (Copyright © 2022.

Background: Chronic obstructive pulmonary disease (COPD) increases susceptibility to sleep disturbances. This study aimed to evaluate the association between COPD severity criteria with sleep quality., Methods: One hundred fifty-eight patients in Rasul Akram Hospital of Iran University of Medical Sciences, Tehran, Iran, from April 2019 to March 2021 diagnosed with COPD were examined using the Pittsburgh Sleep Quality Index (PSQI), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnoea scale, spirometry and pulse oximetry., Results: Of 158 subjects, 125 patients were male (79%), and 33 were female (21%). The mean subject's age and FEV1/FVC ratio were 62.6 ± 11.5 and 65.6 ± 14.9%, respectively. The mean CAT scoring and Spo2 saturation reported 16.2 ± 7 and 91.5 ± 10.8%, respectively. The mean PSQI score was 8.2 ± 3.8. The association between PSQI score with FEV1 and FEV1/FVC ratio was not statistically significant (p = 0.64 and 0.58, respectively), whereas the association between PSQI scores with CAT score (p ˂ 0.0001, r 2  = 0.51) and dyspnoea severity (p ˂ 0.0001, r 2  = 0.29) were statistically significant. The patients with higher CAT score demonstrated poor sleep quality, particularly in longer sleep latency (p = 0.001, r 2  = 0.056), bad subjective sleep quality (p ˂ 0.0001, r 2  = 0.286), lower sleep efficiency (p = 0.002, r 2  = 0.077), higher sleep disturbance (p ˂ 0.0001, r 2  = 0.225), daytime dysfunction (p ˂ 0.0001, r 2  = 0.259) and sleep medication intake times a week (p = 0.01, r 2  = 0.069). Dyspnoea severity was attributed to bad subjective sleep quality (p ˂ 0.0001, r 2  = 0.069), higher sleep disturbances (p = 0.005, r 2  = 0.08), and daytime dysfunction (p ˂ 0.0001, r 2  = 0.108)., Conclusion: The PSQI has a significant association with the CAT and mMRC for COPD patients and is linked to the disease's severity., (© 2021 John Wiley & Sons Ltd.)

Expression dysregulation of the neuron-specific gene, RASGEF1C (RasGEF Domain Family Member 1C), occurs in late-onset neurocognitive disorders (NCDs), such as Alzheimer's disease. This gene contains a (GGC)13, spanning its core promoter and 5' untranslated region (RASGEF1C-201 ENST00000361132.9). Here we sequenced the (GGC)-repeat in a sample of human subjects (N = 269), consisting of late-onset NCDs (N = 115) and controls (N = 154). We also studied the status of this STR across various primate and non-primate species based on Ensembl 103. The 6-repeat allele was the predominant allele in the controls (frequency = 0.85) and NCD patients (frequency = 0.78). The NCD genotype compartment consisted of an excess of genotypes that lacked the 6-repeat (divergent genotypes) (Mid-P exact = 0.004). A number of those genotypes were not detected in the control group (Mid-P exact = 0.007). The RASGEF1C (GGC)-repeat expanded beyond 2-repeats specifically in primates, and was at maximum length in human. We conclude that there is natural selection for the 6-repeat allele of the RASGEF1C (GGC)-repeat in human, and significant divergence from that allele in late-onset NCDs. STR alleles that are predominantly abundant and genotypes that deviate from those alleles are underappreciated features, which may have deep evolutionary and pathological consequences., (© 2021.

Background: Psychological-related disorders such as obesity are a key contributor to morbidity and mortality., Aims: To assess the association between general and abdominal obesity with depression and anxiety among Iranian health-care staff., Methods: This cross-sectional study was conducted under the framework of the Study on the Epidemiology of Psychological Alimentary Health and Nutrition. A total of 4361 Iranian health-care staff were analysed for general obesity and 3213 for central obesity. Overweight and obesity was defined as body mass index 25.0-29.9 and ≥ 30.0 kg/m², respectively. Abdominal obesity was defined as waist circumference (WC) ≥ 88 cm for females and ≥ 102 cm for males. The Iranian validated versions of the Hospital Anxiety and Depression Scale and the General Health Questionnaire were used to assess depression and anxiety., Results: Stratified analysis by sex revealed no significant relationship between general obesity, depression and anxiety among males. However, we found an inverse association between abdominal obesity (WC > 102 cm) and severe depression among males. In females, abdominal obesity was significantly associated with anxiety, before and after taking confounders into account. No significant association was seen between abdominal obesity and psychological distress in either sex after controlling for potential confounders., Conclusions: Abdominal obesity was associated with anxiety in Iranian adult females but not in males. Further studies, particularly prospective research, are required to confirm these findings., (Copyright © World Health Organization (WHO) 2021. Open Access. Some rights reserved.

Background: Few studies have assessed adherence to the Mediterranean diet in relation to psychological health, in particular in the Middle East. Objective: To examine the association between adherence to Mediterranean dietary pattern and prevalence of psychological disorders among a large population of Iranian adults. Design: In this cross-sectional study on 3172 Iranian adults aged 18-55 years, we used a validated food frequency questionnaire for the assessment of dietary intakes. Adherence to the Mediterranean dietary pattern was examined using the Trichopoulou et al. method. To assess psychological health, the Iranian validated version of the Hospital Anxiety and Depression Scale (HADS) was used. Psychological distress was assessed through the use of General Health Questionnaire (GHQ). Results: Mean age of study participants was 36.54 ± 4.97 years. After controlling for potential confounders, participants with the greatest adherence to the Mediterranean diet had lower odds for depression (OR: 0.60, 95% CI: 0.46-0.78), anxiety (OR: 0.61, 95% CI: 0.42-0.86) and psychological distress (OR: 0.60, 95% CI: 0.45-0.79) compared with those with the lowest adherence. When the association with components of Mediterranean diet was examined, we found that high intake of fruits and vegetables was associated with a lower odds of depression, anxiety and psychological distress. In contrast, high intake of grains was positively associated with depression, anxiety and psychological distress. Conclusion: We found evidence indicating an inverse association between adherence to Mediterranean dietary pattern and odds of psychological disorders including depression, anxiety and psychological distress.

Purpose/introduction: There is no study on the association of empirically derived food-based dietary inflammatory index (FDII) and risk of psychological disorders. We investigated the association between FDII and odds of psychological disorders in Iranian adults. Methods and materials: In this cross-sectional study, data on dietary intakes of 3363 Iranian adult participants were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire. FDII score was constructed based on participants' dietary intakes of 28 pre-defined food groups. The Iranian validated version of Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ) was used to assess psychological disorders. Depression, anxiety and psychological distress were defined based on standard criteria. Results: After controlling for potential confounders, participants in the top quintile of FDII score had a greater odds of depression (OR: 1.49; 95% CI: 1.08-2.06), anxiety (OR: 1.92; 95% CI: 1.24-2.96), and psychological distress (OR: 1.55; 95% CI: 1.10-2.19) compared with those in the bottom quintile. When we did the analyses stratified by gender, we found a significant positive association between FDII score and depression (OR: 1.57; 95% CI: 1.04-2.35), anxiety (OR: 1.99; 95% CI: 1.19-3.34), and psychological distress (OR: 1.68; 95% CI: 1.10-2.56) among women comparing the highest and the lowest quintiles. We found no significant association between FDII score and psychological disorders in men. Conclusion: We found that greater FDII score was positively associated with psychological disorders. In the gender-stratified analysis, this was seen in women but not in men.

The authors investigate the association of breakfast skipping and its interaction with a dietary inflammatory index (DII) with the severity of psychological disorders. A total of 2876 Iranian general adults were enrolled in this cross-sectional study. Psychological problems profile score was calculated using the regression method in the framework of factor analysis based on depression, anxiety and psychological distress. The higher scores indicate more severity of mental problem. The frequency of breakfast eating in a week was assessed. Dietary intakes were assessed using a food-frequency questionnaire and twenty-seven items were included in the calculation of DII. In the crude model, individuals who ate breakfast seldom had the highest odds for having worse psychological problems profile (OR 3⋅59; 95 % CI 2⋅52, 5⋅11). Adjustment for various confounders did not change the associations (OR 3⋅35; 95 % CI 2⋅11, 5⋅32). In the adjusted multinomial logistic regression model, participants with high DII (>median) who skipped breakfast had highest risk of being in the higher tertiles of psychological problems profile compared with those who had low DII (

Background: There is no previous study that examined the association between branched-chain amino acids (BCAAs) intake and odds of psychological disorders. The aim of this study was to investigate the association between dietary BCAAs and odds of psychological disorders including depression, anxiety, and psychological distress in a large sample of Iranian adults., Methods: In this cross-sectional study on 3175 Iranian adults aged 18-55 years, a validated food frequency questionnaire was used to assess dietary intakes. BCAAs intake was computed by summing up the amount of valine, leucine, and isoleucine intake from all food items in the questionnaire. Psychological health was examined through the use of Iranian validated version of the Hospital Anxiety and Depression Scale (HADS). Psychological distress was assessed using General Health Questionnaire (GHQ). For depression and anxiety, scores of 8 or more on either subscale were considered as psychological disorders and scores of 0-7 were defined as "normal". In terms of psychological distress, the score of 4 or more was defined as psychological distress., Results: Mean age of study participants was 36.2 ± 7.8 years. Overall, 26.4% (n = 837) of study subjects had depression, 11.9% (n = 378) had anxiety and 20.9% (n = 665) were affected by psychological distress. After controlling for potential confounders, participants in the highest tertile of total BCAAs intake had lower odds of depression (OR: 0.76; 95% CI: 0.60-0.96) and anxiety (OR: 0.66; 95% CI: 0.47-0.91) compared with those in the lowest tertile. Participants in the top tertile of valine intake had a lower odds of depression (OR: 0.76; 95% CI: 0.60-0.96) and anxiety (OR: 0.65; 95% CI: 0.47-0.90) compared with those in the bottom tertile. A significant inverse association was also seen between leucine intake and depression (OR: 0.77; 95% CI: 0.61-0.98) and anxiety (OR: 0.66; 95% CI: 0.47-0.91). In addition, a significant inverse association was observed between isoleucine intake and odds of depression (OR: 0.75; 95% CI: 0.59-0.95) and anxiety (OR: 0.62; 95% CI: 0.45-0.86). There was no significant association between isoleucine intake and odds of psychological distress., Conclusion: Evidence indicating an inverse association between dietary intake of BCAAs and odds of depression and anxiety was found. Prospective studies are required to confirm these findings.

Objective: Although lifestyle-related factors have separately been examined in relation to functional gastrointestinal disorders (FGIDs), there is no epidemiological data on the combined association of lifestyle factors with these conditions. We aimed to examine how combinations of several lifestyle factors were associated with functional dyspepsia (FD), its symptoms, and gastroesophageal reflux disease (GERD) in a large group of Iranian adults., Design, Setting, and Subjects: In a cross-sectional study on 3,363 Iranian adults, we calculated the "healthy lifestyle score" for each participant by summing up the binary score given for 5 lifestyle factors, including dietary habits, dietary intakes, psychological distress, smoking, and physical activity. A dish-based 106-item semi-quantitative validated food frequency questionnaire, General Practice Physical Activity Questionnaire, General Health Questionnaire, and other pre-tested questionnaires were used to assess the components of healthy lifestyle score. To assess FGIDs, a validated Persian version of ROME III questionnaire was used., Results: After adjustment for potential confounders, we found that individuals with the highest score of healthy lifestyle had 79 and 74% lower odds of FD (OR: 0.21; 95% CI: 0.05-0.92) and GERD (OR: 0.26; 95% CI: 0.09-0.69), respectively, compared with those with the lowest score. They were also less likely to have early satiation (OR: 0.28; 95% CI: 0.11-0.73), postprandial fullness (OR: 0.22; 95% CI: 0.09-0.50), and epigastric pain (OR: 0.44; 95% CI: 0.21-0.92). In addition to the combined healthy lifestyle score, low levels of psychological distress, a healthy diet, healthy dietary habits, and nonsmoking were separately and protectively associated with FGIDs., Conclusion: We found that adherence to a healthy lifestyle was associated with lower odds of GERD, FD, and its symptoms in this group of Iranian adults, in a dose-response manner. Individual lifestyle-related factors were also associated with these conditions., (© 2020 S. Karger AG, Basel.)

Purpose: Although considerable research has been devoted to the link between consumption of legume and nuts and metabolic abnormalities, few studies have examined legume and nut consumption in relation to psychological disorders. The current study aimed to examine the association of legume and nut consumption with depression, anxiety and psychological distress in Iranian adults., Methods: This cross-sectional study was carried out among 3172 adult participants aged 18-55 years. Assessment of legume and nut consumption was conducted using a validated dish-based 106-item semi-quantitative food frequency questionnaire. The Iranian validated version of Hospital Anxiety and Depression Scale (HADS) was used to examine psychological health. Scores of 8 or more on either subscale in the questionnaire were considered to indicate the presence of depression or anxiety. Data on psychological distress were collected using the General Health Questionnaire (GHQ), in which the score of 4 or more was considered as having psychological distress., Results: The mean age of participants was 36.5 ± 7.9 years. In the fully adjusted model, men in the top quintile of legume and nut consumption were 66% less likely to be anxious than those in the bottom quintile (OR 0.34; 95% CI 0.14-0.82). However, such significant relationship was not observed among women (OR 1.06; 95% CI 0.63-1.77). We failed to find any other significant association between legume and nut consumption and depression or psychological distress after adjustment for potential confounders either in men or women., Conclusions: We found that consumption of legume and nuts was associated with lower odds of anxiety in men, but not in women. No other significant association was seen among participants. Legume and nut consumption might be promising and, along with medications, could be used to prevent, control or delay psychological disorders.

Objective: The prevalence of depression and anxiety is increasing worldwide. Diet as a modifiable factor for mental health has received great attention. The aim of the present study was to evaluate the association of vitamin B6 intake with depression and anxiety. Methods: This cross-sectional study was performed among 3362 adults in 2011. Anxiety and depression were evaluated using an Iranian validated version of the Hospital Anxiety and Depression Scale (HADS) questionnaire. Dietary intakes were evaluated by a validated 106 item self-administered Willett-format dish-based semi quantitative food-frequency questionnaire (DFQ). Results: The mean intake of vitamin B6 (mg/day) was significantly lower in anxious (1.93 ± 0.74 vs. 2.0 ± 0.74; P = 0.02) and depressed (1.86 ± 0.72 vs. 1.99 ± 0.74; P = 0.001) people than healthy participants. The lower level of vitamin B6 intake (tertile 1), after adjustment for the impacts of various confounding variables, in total population and women was associated with the higher odds of depression (OR = 1.41; 95% CI: 1.19, 2.31; P < 0.001. OR = 1.33; 95% CI: 1.08, 2. 21; P = 0.02, respectively). Also, the lower level of vitamin B6 intake (tertile 1) in total population and women was associated with the higher odds of anxiety (OR = 2.30; 95% CI: 1.31, 4.04; P < 0. 001, OR = 2.30; 95% CI: 1.19, 4.46; P = 0.04). Conclusion: The association of lower intakes vitamin B6 intake with increased risk of depression and anxiety was clearly supported by current study. A reasonable approach to tackle these disorders could be the improvement of nutritional status, accordingly large randomized controlled trials are suggested for providing more evidence.

Purpose: Hyperinsulinemia is linked to the development of various chronic diseases, especially obesity given to the role of insulin responses in body fat accumulation; hence, the current study aimed to examine the association of insulinemic potential of the diet with general and abdominal obesity among a large population of Iranian adults., Methods: This cross-sectional study was carried out among 8691 adult participants aged 18-55 years. Dietary data were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire. Dietary insulin index (DII) was computed through considering food insulin index values published earlier. Dietary insulin load (DIL) was also calculated using a standard formula. Assessment of anthropometric measures was conducted through a self-administered questionnaire. General obesity was defined as body mass index ≥ 25 kg/m 2 , and abdominal obesity as waist circumference ≥ 94 cm for men and ≥ 80 cm for women., Results: Mean age of study participants was 36.8 ± 8.1 years; 60.3% were women. Compared with the lowest quintile, women in the highest quintile of DIL were less likely to be abdominally obese (OR 0.73; 95% CI 0.57-0.92). Such significant association was not seen after controlling for potential confounders (OR 0.86; 95% CI 0.44-1.67). Neither in crude nor in adjusted models, we observed a significant association between DIL and general obesity among men and women. In terms of dietary insulin index, men in the top quintile of DII were more likely to be generally overweight or obese compared with those in the bottom quintile (OR 1.27; 95% CI 1.00-1.62). This association became non-significant after controlling for demographic characteristics (OR 1.14; 95% CI 0.84-1.56). Furthermore, in thefully adjusted model, women in the top quintile of DII were more likely to have general obesity compared with those in the bottom quintile (OR 1.40; 95% CI 1.07-1.84)., Conclusions: We found that adherence to a diet with a high DII was associated with greater odds of general obesity among women, but not in men. Although such information might help to draw conclusions on the practical relevance of the shown findings, further studies, specifically of prospective design, are warranted.

Objective: Although dietary patterns have been evaluated in relation to psychological disorders, their associations with psychosomatic complaints are unclear. We investigated relations of dietary patterns with psychosomatic complaints profiles. Methods: In this cross-sectional study, a total of 3363 adults were included. Dietary intakes and psychosomatic complaints were assessed using self-administered Persian validated questionnaires. Dietary patterns and psychosomatic symptom profiles were identified using exploratory factor analysis. Results: Three dietary patterns and four psychosomatic complaints profiles were identified. Individuals in the top tertile of traditional diet had lower odds for gastrointestinal somatic complaints (odds ratio (OR)= 0.68, 95% confidence interval (CI): 0.50, 0.91). Individuals in the top tertile of healthy diet had lower odds for psychological (OR= 0.68, 95% CI: 0.51, 0.90), gastrointestinal (OR= 0.65, 95% CI: 0.49, 0.87), neuro-skeletal (OR= 0.66, 95% CI: 0.45, 0.96), and pharyngeal- respiratory somatic complaints (OR= 0.61, 95% CI: 0.47, 0.79). Individuals in the top tertile of Western diet had greater odds for psychological somatic complaints (OR= 1.50, 95% CI: 1.13, 2.00) than those in the first tertile. Discussion: The healthy dietary pattern is inversely related to the risk of psychosomatic complaints, whereas the Western diet might be associated with increased risk of psychosomatic complaints.

Studies exploring excessive Internet use and gambling are rapidly expanding concerns regarding its impact on mental health, especially in young people due to the increased prevalence of Internet and gambling addictions. Research suggests that perceived peer support plays a significant role in adolescents' psychological well-being. However, no empirical study has dealt with the mediating effect of perceived peer support on the relationship between Internet and gambling addictions and psychological well-being. Thus, the present study aimed to examine whether perceived peer support mediates the relation between Internet and gambling addictions and psychological well-being of adolescents. A sample of 347 Iranian adolescents aged 14 to 18 (Mean age 16.14, 50.4% male) who were studying in Kuala Lumpur, Malaysia participated in this study. Subjective Vitality Scale (SVS), Compulsive Internet Use Scale (CIUS), Six-item Social Support Questionnaire (SSQ6), and The South Oaks Gambling Screen (SOGS) were used to collect data. Mediation analyses showed a significant indirect effect of compulsive Internet use and problem gambling on psychological well-being through perceived peer support. The total effects of compulsive Internet use and problem gambling on psychological well-being were negative. This study implies the significance of strengthening the knowledge about the impact of peer relationships among adolescents.

Background and Objective: Few studies have evaluated the association of personality traits with functional dyspepsia (FD). In the present study, we aimed to explore the relationship between different personality traits and FD in a sample of Iranian adults., Methods: This cross-sectional study was conducted on 4763 adults. FD was evaluated using a modified and validated Persian version of the Rome III questionnaire for the diagnosis of functional gastrointestinal disorders. Personality traits were assessed using the five-factor model. Logistic regression was used for data analysis., Results: After controlling for various potential confounders, neuroticism (OR = 1.043; 95% CI: 1.028, 1.059), agreeableness (OR = 0.965; 95% CI: 0.952, 0.978), extraversion (OR = 0.985; 95% CI: 0.970, 0.990), openness (OR = 0.981; 95% CI: 0.966, 0.996), and conscientious (OR = 0.980; 95% CI: 0.968, 0.991) scores were associated with risk of FD. Similar significant associations were observed in stratified analyses by sex, except for openness which tended to decrease the risk of FD marginally in women (OR = 0.983, 95% CI: 0.966, 1.001) and in men (OR = 0.979, 95% CI: 0.955, 1.003) after adjusting for multiple confounding variables., Conclusion: Our study showed that the higher scores of extraversion, conscientiousness, openness, and agreeableness are independently associated with a lower risk of FD in Iranian general population while higher scores of neuroticism increase the risk of FD., (Copyright © 2019 Elsevier Inc.

The present study was carried out to determine whether the dietary insulin index (DII) and dietary insulin load (DIL) are related to psychological disorders in a cross-sectional study among adults. A total of 3172 Iranian adults (age range of 18-55 years) were included. Data on dietary intakes were collected using a validated dish-based 106-item semi-quantitative FFQ. DII and DIL were calculated using food insulin index values published earlier. To assess depression and anxiety, an Iranian validated version of the Hospital Anxiety and Depression Scale was used. Furthermore, psychological distress was examined using the General Health Questionnaire. Among women, a significant positive association was seen; such that women in the highest quartile of DIL had higher odds of depression than those in the lowest quartile (OR 1·84; 95 % CI 1·14, 2·96). In terms of DII, in the fully adjusted model, women in the top quartile of DII were more likely to be depressed compared with those in the bottom quartile (OR 1·65; 95 % CI 1·05, 2·58). In conclusion, we found a significant positive association between DIL and DII and odds of depression among women, but not in men. However, such findings were not seen for anxiety and psychological distress.

Background: Approximately 2% of the human core promoter short tandem repeats (STRs) reach lengths of ≥6 repeats, which may in part be a result of adaptive evolutionary processes and natural selection. A single-exon transcript of the human nescient helix loop helix 2 (NHLH2) gene is flanked by the longest CA-repeat detected in a human protein-coding gene core promoter (Ensembl transcript ID: ENST00000369506.1). NHLH2 is involved in several biological and pathological pathways, such as motivated exercise, obesity, and diabetes., Methods: The allele and genotype distribution of the NHLH2 CA-repeat were investigated by sequencing in 655 Iranian subjects, consisting of late-onset neurocognitive disorder (NCD) as a clinical entity (n = 290) and matched controls (n = 365). The evolutionary trend of the CA-repeat was also studied across vertebrates., Results: The allele range was between 9 and 25 repeats in the NCD cases, and 12 and 24 repeats in the controls. At the frequency of 0.56, the 21-repeat allele was the predominant allele in the controls. While the 21-repeat was also the predominant allele in the NCD patients, we detected significant decline of the frequency (p < 0.0001) and homozygosity (p < 0.006) of this allele in this group. Furthermore, 12 genotypes were detected across 16 patients (5.5% of the entire NCD sample) and not in the controls (disease-only genotypes; p < 0.0003), consisting of at least one extreme allele. The extreme alleles were at 9, 12, 13, 18, and 19 repeats (extreme short end), and 23, 24, and 25 repeats (extreme long end), and their frequencies ranged between 0.001 and 0.04. The frequency of the 21-repeat allele significantly dropped to 0.09 in the disease-only genotype compartment (p < 0.0001). Evolutionarily, while the maximum length of the NHLH2 CA-repeat was 11 repeats in non-primates, this CA-repeat was ≥14 repeats in primates and reached maximum length in human., Conclusion: We propose a novel locus for late-onset NCD at the NHLH2 core promoter exceptionally long CA-STR and natural selection at this locus. Furthermore, there was indication of genotypes at this locus that unambiguously linked to late-onset NCD. This is the first instance of natural selection in favor of a predominantly abundant STR allele in human and its differential distribution in late-onset NCD., (© 2020 S. Karger AG, Basel.)

Background: Although individual macronutrients were studied in relation to mental health, no information exist about the association between adherence to low carbohydrate diet and psychological disorders. This study was conducted to investigate the association between adherence to a low carbohydrate diet and prevalence of psychological disorders among Iranian adults., Methods: In this cross-sectional study on 3362 adult men and women, dietary intakes were examined by the use of a validated semi-quantitative food frequency questionnaire. Low carbohydrate diet (LCD) score was computed for each participant based on deciles of percentages of energy from macronutrients. Then the scores of carbohydrate, protein and fat intake for each participant were summed up to achieve the overall LCD score, which ranged from 3 (highest carbohydrate intake and lowest fat and protein intakes) to 30 (lowest carbohydrate intake and highest fat and protein intakes). Anxiety, depression, and psychological distress were assessed by validated Iranian versions of the Hospital Anxiety and Depression Scale and General Health Questionnaire-12., Results: Prevalence of depression, anxiety and psychological distress in the whole population were 28.0, 13.3 and 22.6%, respectively. No significant differences were observed in the distribution of depression, anxiety and psychological distress across different quartiles of LCD score. After controlling for potential confounders, no significant association was seen between LCD score and prevalence of depression (OR for the highest vs. the lowest quartile of LCD score: (1.15; 95% CI: 0.93, 1.39). Consumption of LCD was not also associated with increased risk of anxiety (0.82; 95% CI: 0.59, 1.14) and psychological distress (0.92; 95% CI: 0.72, 1.16). These associations did not alter when the analyses were done stratified by gender or BMI status., Conclusion: Adherence to the low carbohydrate diet, which contains high amount of fat and proteins but low amounts of carbohydrates, was not associated with increased odds of psychological disorders including depression, anxiety and psychological distress. Given the cross-sectional nature of the study which cannot reflect causal relationships, longitudinal studies, focusing on types of macronutrients, are required to clarify this association.

Background: The purpose of this study was to explore the association of five factors personality traits, as predictor variables, with the anxiety and depression as joint dependent variables in an Iranian adult population., Subjects and Methods: A total of 3175 subjects living in Isfahan participated in this cross-sectional population-based study (SEPAHAN) and completed self-administered questionnaires about demographic, life style, gastrointestinal disorders, personality traits, social support, and psychological problems. Data was analyzed using bivariate multiple binary logistic regression in R Free statistical software., Results: The results indicated high scores of neuroticisms increase the risk of anxiety and depression after adjustment for the potential confounders in total sample (OR (95% CI): 1.22 (1.19-1.24) and 1.19 (1.17-1.21), respectively) as well as in both male and female. In contrast, joint inverse associations were found between anxiety and depression with high extraversion (OR (95% CI): 0.90 (0.88-0.92) and 0.91 (0.89-0.92), respectively), agreeableness (0.93 (0.91-0.96) and 0.94 (0.92-0.96) respectively) and conscientiousness scores (0.95 (0.93-0.97) and 0.95 (0.94-0.97) respectively) as well as in both male and female. Furthermore, higher scores of openness had significant inverse association with depression in male., Conclusion: The present study indicated that higher scores of neuroticism, however lower extraversion, conscientiousness and agreeableness scores are risk factors for both anxiety and depression in Iranian adult population. It is suggested to perform family studies or twin and genetic association studies with considering combinations of personality traits (personality styles), and also measuring personality traits at the facet level.

Background & Aims: Limited data are available on the association of inflammatory potential of the diet and odds of psychological disorders. We investigated the association between adherence to a pro-inflammatory diet, as measured by Dietary Inflammatory Index (DII), and odds of psychological disorders., Methods: In this cross-sectional study, dietary intakes of 3363 Iranian adult participants were collected using a validated Dish-based 106-item Semi-quantitative Food Frequency Questionnaire (DS-FFQ). DII score was calculated based on participants' dietary intakes obtained from DS-FFQ. The Iranian validated version of Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ) was used to assess psychological disorders. For depression and anxiety, scores of 8 or more on either subscale were considered as psychological disorders and scores of 0-7 were defined as "normal". In terms of psychological distress, the score of 4 or more was defined as psychological distress., Results: Overall, 28% (n = 943) of study participants had depression, 13.3% (n = 448) were affected by anxiety and 22.6% (n = 760) by psychological distress. After controlling for potential confounders, individuals in the highest quintile of DII score had higher scores of depression (6.56 ± 0.16 vs. 5.48 ± 0.16; P < 0.001), anxiety (3.85 ± 0.17 vs. 3.09 ± 0.17; P = 0.006), and psychological distress (2.42 ± 0.13 vs. 1.77 ± 0.13; P = 0.001), compared with those in the lowest quintile. Participants in the top quintile of DII score had greater odds of depression (OR: 1.84, 95% CI: 1.30-2.60), anxiety (OR: 1.69, 95% CI: 1.07-2.67), and psychological distress (OR: 1.72, 95% CI: 1.20-2.46) than those in the bottom quintile., Conclusions: We found that adherence to a pro-inflammatory diet was positively associated with psychological disorders., (Copyright © 2018 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Objectives: Although several studies are available that link individual dietary antioxidants to the risk of psychological disorders, data about the association of dietary total antioxidant capacity (TAC) with depression and anxiety are scarce. This study was conducted to investigate the association between dietary TAC and odds of depression and anxiety among Iranian adults., Methods: In this cross-sectional study, the dietary intakes of 3297 apparently healthy adults in the Isfahan province of Iran were assessed using a validated food-frequency questionnaire. Dietary TAC was estimated using the ferric-reducing antioxidant power international databases. Depression and anxiety were assessed using a validated Persian translated version of the Hospital Anxiety and Depression Scale questionnaire. Scores of 0 to 7 in either subscales of the questionnaire were considered normal, and scores of ≥8 indicated the presence of depression or anxiety., Results: Overall, 943 study participants (28.6%) were depressed, and 448 participants (13.6%) had anxiety. After controlling for potential confounders, including the dietary intake of omega-3 fatty acids, we found that participants in the top quintile of the dietary TAC were 43% less likely to be depressed than those in the bottom category (odds ratio: 0.57; 95% confidence interval, 0.40-0.82; P trend  = .001). Regarding anxiety, we found an inverse significant association between dietary TAC and anxiety when comparing the extreme quintiles (odds ratio: 0.62; 95% confidence interval, 0.39-0.99; P trend  = .06)., Conclusions: We found an significant inverse association between dietary TAC and odds of depression and anxiety among adults. Further prospective studies are required to confirm these findings., (Copyright © 2018. Published by Elsevier Inc.)

Background: There is no study that examined the association of the MIND diet and odds of psychological disorders. We investigated the association between adherence to the MIND diet and odds of psychological disorders., Methods: A total of 3176 adults were included in this cross-sectional study. Dietary intakes of study participants were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire (DS-FFQ). The MIND diet score was calculated based on participants' dietary intakes obtained from DS-FFQ. To assess depression and anxiety, the Iranian validated version of Hospital Anxiety and Depression Scale (HADS) was used. Psychological distress was examined using General Health Questionnaire (GHQ)., Results: After taking potential confounders into account, participants in the highest quartile of the MIND diet score had a lower odds of depression (OR: 0.68; 95% CI: 0.53-0.89) and psychological distress (OR: 0.68; 95% CI: 0.52-0.89) than those in the lowest quartile. No significant association was observed between consumption of MIND diet and odds of anxiety (OR: 0.72; 95% CI: 0.51-1.03). When we did gender-stratified analyses, no significant association was seen between adherence to the MIND diet and odds of psychological disorders in men; however, women in the top quartile of the MIND diet score had lower odds of depression (OR: 0.60; 95% CI: 0.45-0.81) and psychological distress (OR: 0.66; 95% CI: 0.48-0.90) than those in the bottom quartile., Conclusion: We found that greater adherence to the MIND diet was inversely associated with odds of depression and psychological distress. No significant association was observed between consumption of MIND diet and odds of anxiety., (Copyright © 2019. Published by Elsevier B.V.)

Background & Aims: The association between diet and mental health disorders might be mediated by inflammatory properties of the diet. We evaluated the association between the dietary inflammatory index (DII) and the risk of a worsened mental health disorders profile., Methods: A total of 3363 Iranian adults were included in this cross-sectional study. A mental health disorders profile score was calculated using regression analysis, within the framework of factor analysis, based on anxiety, depression and psychological distress, with a higher scores indicating greater severity of mental problems. Dietary intakes were assessed using a validated dish-based food frequency questionnaire (DFQ). Twenty-seven macro- and micro-nutrients, onions, tea and caffeine were included in the calculation of DII. Each of them received a score based on their inflammatory ability, thus, a greater DII indicated a more pro-inflammatory diet. The odds of being in the highest tertile of mental health disorders profile across the tertiles of DII was assessed using multinomial logistic regression., Results: Either in the crude or fully-adjusted multinomial logistic regression models, participants in the lowest tertile of DII had a lower risk for being in the top tertile of mental health disorders profile (adjusted model: OR: 0.45; 95% CI: 0.33, 0.60; P trend<0.001). In a stratified analysis by sex, similar findings were observed in both genders, although there was only a trend for the associations to be significant in men (men: OR: 0.53; 95% CI: 0.31, 0.90; P trend = 0.070; women: OR: 0.40; 95% CI: 0.27, 0.58; P trend<0.0001)., Conclusions: Our findings suggest a direct association between the pro-inflammatory properties of the diet and an increased risk of higher mental health disorders profile scores. Prospective dietary intervention studies and observational prospective cohorts are required to confirm these findings., (Copyright © 2018 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Purpose: No previous study has examined the associations between egg consumption and prevalence of psychological disorders. The present study was conducted to determine the association between egg consumption and depression in a large sample of Iranian adults., Methods: This cross-sectional study was conducted on 3172 adults in Isfahan, Iran. Egg consumption was assessed by using a validated, self-administered, dish-based, semi-quantitative food frequency questionnaire. The Iranian validated version of Hospital Anxiety and Depression Scale was used to screen for anxiety and depression. The Iranian validated version of General Health Questionnaire with 12 items was used to assess psychological distress. Depression, anxiety and psychological distress were defined according to standard criteria., Results: The mean age of the study participants was 36.5 ± 7.9 years. Depression, anxiety and psychological distress were prevalent among 28.4, 13.6 and 23% of the study subjects, respectively. After controlling for potential confounders, no significant association was observed between egg intake and depression (OR for comparing extreme quartiles: 1.08; 95% CIs 0.80-1.45) and anxiety (OR 0.79; 95% CIs 0.54-1.16), as well as psychological distress (OR 1.03; 95% CIs 0.76-1.41) in the whole population. In men, significant positive associations were observed between egg intake and depression before controlling for BMI (OR 1.68; 95% CIs 1.01-2.80); however, the associations became non-significant after taking BMI into account (OR 1.62; 95% CIs 0.96-2.72)., Conclusions: We found no significant association between egg intake and psychological disorders. Further studies, in particular of prospective design, are warranted.

Background: Somatic syndrome is one of the remarkably prevalent issues in primary health care and subspecialty settings. We aimed to elucidate multidimensional associations between somatic symptoms with major mental problems and personality traits in the framework of the quantile regression model with a Bayesian approach., Methods: A total of 4763 employees at Isfahan University of Medical Sciences and Health Services in Isfahan province, Iran, filled out four validated questionnaires including Hospital Anxiety and Depression Scale (HADS), NEO Questionnaire, General Health Questionnaire (GHQ) and PHQ-15 for somatic symptom severity. In addition, Functional Gastrointestinal Disorders (FGIDs) were determined using Rome IV criteria. Exploratory Factor Analysis (EFA) and Bayesian regularized quantile regression with adaptive LASSO penalization were applied for reduced dimension of somatic symptoms and variable selection and parameter estimation, respectively., Results: The 25 major somatic symptoms were grouped into four factors including general, upper gastrointestinal, lower gastrointestinal and respiratory by EFA. Stress, depression, and anxiety had significant effects on all of the four extracted factors. The effect of anxiety in each four extracted factors was more than stress and depression. Neuroticism and agreeableness had significant effects on all of the four extracted factors, generally (p < 0.05)., Conclusions: Given the high prevalence of somatic symptoms and psychosomatic complaints in correlation with the diverse range of mental co-morbidities, developing more detailed diagnostic tools and methods is crucial; nonetheless, it seems that providing better interdisciplinary approaches in general medical practice is groundwork.

Objective: To determine the relationship between dietary patterns identified by reduced-rank regression method and psychological disorders in a large group of Iranian adults., Methods: A cross-sectional study was performed on 3363 Iranian adults between 20 and 55 years. Dietary intakes were assessed using a validated dish-based semi-quantitative food frequency questionnaire. Psychological health was examined through validated Iranian version of Hospital Anxiety and Depression Scale and General Health Questionnaires. Reduced-rank regression was applied to identify dietary patterns based on the ratio of omega-3/omega-6, zinc, magnesium, vitamin B6, and folic acid intake. Logistic regression was used to assess the relationship between dietary patterns and psychological disorders., Results: Three major dietary patterns were derived: "healthy," "fish and poultry," and "transitional." After adjustment for potential confounders, "healthy" was associated with reduced depression (odds ratio (OR) for the highest vs. lowest quintile: 0.35; 95% confidence interval (CI): 0.25-0.50), anxiety (OR: 0.47; CI: 0.30-0.74), and psychological distress (OR: 0.52; CI: 0.36-0.75). Greater adherence to the "fish and poultry" was related with lower odds of depression (OR: 0.64; CI: 0.47-0.87). Participant in the third quintile of "fish and poultry" dietary pattern were less likely to be anxious (OR: 0.61; CI: 0.41-0.91). Additionally, we found an inverse significant correlation between adherence to the "transitional" dietary pattern and odds of depression (OR: 0.36; CI: 0.21-0.62), anxiety (OR: 0.43; CI: 0.21-0.88), and psychological distress (OR: 0.41; CI: 0.23-0.72)., Conclusion: We found that "healthy," "fish and poultry," and "transitional" dietary patterns have inverse significant relationship with odds of psychological disorders, but prospective studies are needed for causal conclusion.

Purpose: Although several studies have examined the link between different types of carbohydrate consumption and depression and anxiety, limited data are available linking whole and refined grains consumption to psychological disorders. We aimed to investigate the association of whole and refined grains consumption with psychological disorders among Iranian adults., Methods: A total of 3172 adult people with age range of 18-55 years were included in this cross-sectional study. Data on grains consumption were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire. To assess depression and anxiety, Iranian validated version of Hospital Anxiety and Depression Scale (HADS) was applied. Furthermore, psychological distress was examined using General Health Questionnaire (GHQ). Psychological disorders were defined based on standard criteria., Results: Mean age of participants was 36.5 ± 7.9 years. Women in the third quartile of whole grains consumption had lower odds for having anxiety (OR 0.62, 95% CI 0.45-0.85) compared with those in the first quartile. This relationship was also seen even after controlling for potential confounders (OR 0.65, 95% CI 0.44-0.96). In contrast, compared with the first quartile, women in the highest quartile of refined grains consumption had greater odds to have depression (OR 1.76, 95% CI 1.00-3.09) and anxiety (OR 2.03, 95% CI 1.00-4.10) after adjusting for covariates. Such relationships were not observed among men., Conclusion: Moderate consumption of whole grain foods was inversely associated with anxiety in women, but not in men. Furthermore, we found a significant positive association between refined grains consumption, depression and anxiety in women.

The current study aimed to determine the prognostic values of personality traits for common psychological problems in a large sample of Iranian adult. In a large sample of healthy people (n = 4763) who lived in Isfahan province; the NEO-FFI was used to assess the personality traits; depression and anxiety were assessed using the "Hospital Anxiety and Depression Scale (HADS)" also stress was measured through Persian validated version of General Health Questionnaire (GHQ-12). Receiver Operating Characteristics Curve (ROC) analysis was used as main statistical method for data analysis. ROC analysis showed neuroticism was the best predictor for all psychological problems with highest area under the curve (AUC) (95% confidence interval) for stress, 0.837 (0.837-0.851), anxiety 0.861 (0.847-0.876) and depression 0.833 (0.820-0.846) (p < .001) and the corresponding cut-off points (sensitivity, specificity), were 21.5 (77%, 66%), 22.5 (81%, 77%) and 20.5 (77%, 74%), respectively. Other personality traits were significant protective factors for being affected with psychological problems (p < .001). Similar findings were observed separately in women and men. The present study showed that the neuroticism is significant risk factor for being affected with three psychological problems while other traits are significant protective factors. Personality traits are useful indices for screening psychological problems and an effective pathway toward prevention in general population., Competing Interests: All authors declare that they have no conflict of interests., (© Atlantis Press International B.V.)

Objective: Findings from observational studies on the relationship between fruit and vegetables consumption and risk of mental disorders are contradictory. We aimed to examine the association between fruit and vegetables intake and prevalence of depression, anxiety, and psychological distress in a large group of Iranian adults., Methods: This cross-sectional study was conducted on 3362 people of Iranian adults working in 50 health centers. Dietary data were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire (FFQ). The Iranian-validated version of Hospital Anxiety and Depression Scale (HADS) was used to screen for anxiety and depression. The General Health Questionnaire (GHQ) was used to assess psychological distress., Results: The prevalence of depression, anxiety, and high psychological distress among the study population was 30.0, 15.2, and 25.0%, respectively. Women in the top quintile of fruit intake, compared with those in the bottom quintile, had 57, 50, and 60% lower odds of depression, anxiety, and psychological distress. Consumption of vegetables was significantly associated with lower odds of depression (OR 0.65; 95% CI 0.46, 0.93) in women and lower odds of anxiety (OR 0.43; 95% CI 0.22, 0.87) in men. In addition, after adjustment for potential confounders, women in the highest quintile of fruit and vegetables intake, compared with those in the bottom quintile, had significantly lower odds of depression (OR 0.55; 95% CI 0.37, 0.80) and psychological distress (OR 0.60; 95% CI 0.40, 0.90). Furthermore, high intake of total fruit and vegetables was associated with lower odds of psychological distress (OR 0.42; 95% CI 0.21, 0.81) in men., Conclusion: We found significant inverse associations between high intake of fruit with depression, anxiety, and psychological distress in Iranian women. High consumption of vegetables was also associated with lower risk of depression and anxiety, respectively, in women and men. In addition, high intake of total fruit and vegetable was associated with lower odds of depression and psychological distress in women and men.

Findings from clinical trials on the effect of Mg supplementation on depression and anxiety are not generalisable to the community owing to high-dose intervention in short-term periods. Limited observational data are available linking dietary intake of Mg and psychiatric disorders. We aimed to investigate the association between dietary intake of Mg and psychiatric disorders in a large cross-sectional study on Iranian adults. A total of 3172 Iranian adults (with an age range of 18-55 years) were included in this study. Data on dietary intakes were collected using a validated dish-based 106-item semi-quantitative FFQ. To assess depression and anxiety, an Iranian validated version of the Hospital Anxiety and Depression Scale was used. Furthermore, psychological distress was examined using the General Health Questionnaire. The mean age of men and women was 38·4 (sd 8·2) and 35·1 (sd 7·4) years, respectively. In unadjusted analyses, we found that higher dietary Mg intake was associated with lower odds of anxiety among women (OR 0·61; 95 % CI 0·41, 0·90), such that after taking potential confounders into account women in the highest quintile of Mg intake had a 39 % lower odds of anxiety compared with those in the lowest quintile (OR 0·61; 95 % CI 0·40, 0·93). Moreover, deficient Mg intake was positively associated with anxiety among all women (OR 1·80; 95 % CI 1·19, 2·72) and also normal-weight women (OR 1·73; 95 % CI 1·01, 2·95). In addition, a significant inverse association was found between dietary Mg intake and depression among normal-weight men (OR 0·45; 95 % CI 0·20, 0·99) and overweight women (OR 0·45; 95 % CI 0·24, 0·85). In conclusion, dietary intake of Mg was inversely associated with depression and anxiety. However, such findings were not seen for psychological distress.

Introduction: Although empirically derived dietary patterns have been examined in relation to depression, limited data are available linking theory-based dietary patterns and psychological health., Objective: We aimed to investigate the association between adherence to DASH-style diet and psychological health among Iranian adults., Methods: This cross-sectional study was done among 3846 general public adults in Isfahan, Iran. Dietary assessment was conducted using a validated 106-item dish-based semiquantitative food frequency questionnaire. To investigate participants' adherence to DASH-style diet, we created DASH score based on earlier publications focusing on eight components (fruits, vegetables, nuts and legumes, dairy products, grains, sweetened beverages and sweets, sodium, and red and processed meats). Participants were classified into three categories based on their DASH score [low (≤40), moderate (41-50), and high adherence (≥51)]. This categorization, instead of distribution-based classification, was used due to low adherence to the DASH dietary pattern in the study population. Psychological health was examined by means of validated Hospital Anxiety and Depression Scale and General Health Questionnaire. Depression, anxiety, and psychological distress were defined based on standard criteria., Results: We found that moderate adherence to DASH-style diet was associated with lower odds of depression (OR 0.73; 95 % CI 0.59-0.90, P trend  = 0.63) compared with those with the lowest adherence. In our stratified analyses, these associations remained significant for women (0.70; 0.54-0.91) and for normal-weight participants (0.70; 0.52-0.92). Moreover, after controlling for potential confounders, an inverse association was observed between high adherence to DASH-style diet and anxiety in normal-weight participants (0.61; 0.37-0.98). Such associations were also seen between moderate adherence to DASH-eating style and anxiety in overweight or obese individuals (0.63; 0.42-0.95). We failed to find any significant association between consumption of DASH-style diet and psychological distress., Conclusion: We found an inverse association between moderate adherence to DASH dietary pattern and depression. Further prospective studies are required to confirm these findings.

Earlier studies have shown a protective association between adherence to healthy eating guidelines and mental disorders in Western nations; however, data in this regard are limited from the understudied region of Middle East. We examined the association between adherence to healthy eating guidelines, as measured by Alternative Healthy Eating Index (AHEI)-2010, and prevalence of anxiety and depression in a large sample of Iranian adults. In this cross-sectional study, data on dietary intakes of 3363 adult participants were collected using a validated dish-based 106-item semi-quantitative FFQ. Adherence to healthy eating was quantified using AHEI-2010, as suggested by earlier publications. The Iranian validated version of Hospital Anxiety and Depression Scale was used to assess anxiety and depression in study participants. Data on other covariates were gathered using a pre-tested questionnaire. Overall, the prevalence of anxiety and depression was 15·2 % (males 10·8 % and females 18·3 %) and 30·0 % (males 22·9 % and females 35·1 %), respectively. After controlling for potential confounders, those in the top quartile of AHEI-2010 had a 49 % lower chance of anxiety (OR 0·51; 95 % CI 0·35, 0·72) and a 45 % lower odds of depression (OR 0·55; 95 % CI 0·42, 0·72), compared with those in the bottom quartile. Stratified analysis by sex revealed that women in the highest categories of AHEI-2010 had a 49 % lower odds of having anxiety and depression, after adjustment for confounders, but no significant association was found in men. In addition, among individuals who were 40 years old or younger, those with high adherence to AHEI-2010 were 58 and 51 % less likely to have anxiety and depression, compared with those with less adherence. Adherence to healthy eating was inversely associated with a lower chance of anxiety and depression in Iranian adults. Prospective studies are required to confirm these associations in Middle-Eastern populations.

Objectives: Subjective halitosis is a growing concern in the fields of dentistry and psychology. This study was designed to determine the association between subjective halitosis and contributing psychological factors., Methods: Data for this cross-sectional study were gathered from 4,763 participants who had answered questions on subjective halitosis and psychological factors (depression, anxiety, stress and personality traits) in the study on the epidemiology of psychological, alimentary health and nutrition (SEPAHAN). Binary logistic regression was used for data analysis., Result: The mean age of all subjects was 36.58 years; and the majority of subjects were female (55.8%), married (81.2%) and graduates (57.2%). The prevalence of subjective halitosis was 52.8%. The majority of subjects with the complaint of subjective halitosis were married (P<0.001) and young (P=0.07). Participants with subjective halitosis were significantly more anxious [odds ratio (OR)=1.76, 95% confidence interval (95% CI): 1.38-2.24], stressed (OR=1.41, 95% CI: 1.17-1.71) and depressed (OR=1.31, 95% CI: 1.09-1.57). Among personality traits, neuroticism was a risk factor (tertile 1 vs. tertile 2: OR=1.29, 95% CI: 1.09-1.51; and tertile 1 vs. tertile 3: OR=1.74, 95% CI: 1.43-2.13) and conscientiousness was revealed to be a protective factor (tertile 1 vs. tertile 2: OR=0.82, 95% CI: 0.70-0.98; and tertile 1 vs. tertile 3: OR=0.65, 95% CI: 0.53-0.80)., Conclusion: It seems that psychological factors, such as anxiety, depression and stress, as well as some personality traits, can be considered as risk factors for subjective halitosis. Multidisciplinary efforts by dental and psychological professionals must be considered to address this problem., (© 2015 FDI World Dental Federation.)

Introduction: The purpose of this study was to investigate the impact of top management turnover on Strategic Collaborative Quality Management (SCQM) implementation in healthcare organizations. The role of top management turnover in the process and impact of the SCQM model was investigated using a case study of a public hospital., Methods: Both qualitative and quantitative methods were used for data collection., Results and Discussion: Top management turnover is a major threat to the long-term success of the SCQM intervention and makes it very difficult to sustain its benefits. Successful quality management implementation needs supportive and committed leadership and management. Top management stability encourages long-term planning and commitment to pursuing long-term objectives., Conclusion: This paper has highlighted the critical role of top management stability during the course of quality management implementation.

Background: Coronary artery disease is the leading cause of death in industrialized countries and most patients with diabetes die from complications of atherosclerosis. The objective of this study was to determine the presence of diabetes mellitus and other conventional coronary heart disease risk factors (cigarette smoking, hypertension and hyperlipidemia) in patients with acute coronary events in an Iranian population., Methods: The study included 514 patients with unstable angina or myocardial infarction (MI) out of 720 patients admitted to CCU ward of a general hospital from March 2003 to March 2005. History of diabetes, hypertension and cigarette smoking, demographic indices, coronary heart disease and diabetes mellitus treatment, myocardial enzymes, serum triglycerides (TG) and cholesterol and fasting and non fasting blood glucose levels and HbA1C of diabetics were recorded of admission sheets. The data were structured to appropriate one way ANOVA, T tests, and chi square test with SPSS 13 product for windows., Results: Out of all patients 35.8% were female, 30% were diabetics (Duration 13.4 +/- 8.7 years), 42% were smoker and 91% were hypertensive. Twenty four percent had MI and 76% had unstable angina. MI was significantly higher in diabetic patients (36.4% vs. 19.2%, P < 0.001). Location and extension of MI and myocardial enzymes did not differ between diabetics and non-diabetic patients. Diabetic patients were older than non diabetics (65 +/- 11.6 vs. 59.7 +/- 12.5 years, p < 0.05). Five (66.7%) out of 9 patients with fatal MI were diabetics (Odds Ratio = 2.98). Age, duration of diabetes and HbA1c levels, did not differ between diabetic patients with or without MI. Hypertension and current smoking was significantly higher in patients with MI compared to patients with unstable angina (p < 0.05). Serum TG, HDL-C, LDL-C and total cholesterol level did not differ between patients with MI and unstable angina. Diabetic patients compare to non diabetic patients were more hypertensive (96% vs. 88.7%, p < 0.005) and had higher serum triglyceride (TG over 200 mg/dl, 35.1% vs. 26.4, p <0.05). Diabetes was more frequent among women than men (36.4% vs. 26.4%, p < 0.05). Women were older than men (65 +/- 11.6 vs. 59.2 +/- 13 years, p < 0.005) and had higher total serum cholesterol (200 +/- 41.8 vs. 192 +/- 42.5 mg/dl, p < 0.05) and HDL-C levels (49.7 +/- 22 vs. 40 +/- 13 mg/dl, p < 0.005). Ninety seven percent of all patients had at least one of cardiovascular risk factors (hypertension, smoking, diabetes, high cholesterol and low HDL-cholesterol levels)., Conclusion: In this study 19 out of 20 patients with acute coronary event have at least one of conventional cardiac risk factors. Diabetes and hypertension are leading risk factors, which may directly or indirectly interfere and predict more serious complications of coronary heart disease.

As the century has just changed for the Western calendar it should be borne in mind that for a vast part of the world the centuries are rolling at a different time and under different conditions. So, although we live and trade in a "global village", we are yet divided by time, space, and ideologies. The hope is that the 21st century will enable us to have a closer look at each other and that the global networks, the web sites, and the electronic mailing systems, will work as a bridge rather than as a new means of widening the gaps. This article is a plea for a better understanding of the different priorities and views that Islamist women have of themselves, of their place in history, and what it is that they need to fight for. It is also a call for the universality of sisterhood and a wish that the solidarity that was forged in the latter part of the 20th century will not be fragmented into smithereens in the new millennium.
