Food security and its association with socioeconomic status and dietary diversity in free living older people in Tehran, Iran. BMC Geriatr 2024; 24:128. [PMID: 38308219 PMCID: PMC10836019 DOI: 10.1186/s12877-024-04705-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 01/11/2024] [Indexed: 02/04/2024] Open
Abstract
BACKGROUND Food security is a function of food access and dietary diversity. Older age is a period when adequate and diverse dietary intake is a challenge. This study aimed to investigate the association between food security on the one hand and dietary diversity and socioeconomic factors on the other hand among the free-living older people in the city of Tehran. METHODS In this cross-sectional study, 583 older people, aged 60-80 years living in Tehran city, were selected through the systematic cluster sampling method. Food security was determined by the United States Household Food Security Survey Module (US-HFSSM (.Socioeconomic status (SES) and two 24-h recalls were obtained. Dietary Diversity Score (DDS) was calculated using the FAO 2010 guideline. Multinomial logistic regression was applied. RESULTS The average age of participants was 67.87 ± 5.86 years. Based on US-HFSSM, 56.9% of older people were food secure; while 25.7%, 14.2% and 3.2% suffered from food insecurity (FI) without hunger, with moderate hunger, and with severe hunger, respectively. There was no association between FI and DDS, even after controlling for confounders. FI with mild hunger was associated with household income (OR = 2.744, 95% CI = 1.100-6.846), while FI with severe hunger was associated with Fars ethnicity (OR = 0.146, 95% CI = 0.051-0.424). CONCLUSIONS Overall, socio-economic status and demographic characteristics were the predictors of FI among older people. The findings can have implication in design and targeting of interventions directed at older people.

Real-world practices in reproductive health and counselling for women with epilepsy: A Canadian perspective. Epilepsy Behav 2024; 151:109623. [PMID: 38262329 DOI: 10.1016/j.yebeh.2024.109623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/27/2023] [Accepted: 01/02/2024] [Indexed: 01/25/2024]
Abstract
Canadian women of reproductive potential living with epilepsy present unique care challenges due to the complex interplay of hormones, seizures, and medications. This study explores reproductive health practices and counselling for women with epilepsy. Through a questionnaire developed by the Canadian League Against Epilepsy women with epilepsy (WWE) workgroup, we are the first to report demographic and real-world practice characteristics of Canadian healthcare professionals providing care for WWE with specific focus on family planning, birth plans, and postpartum care counselling. Among respondents, 76.9% routinely reviewed contraception with patients and an intrauterine device (IUD) was the most popular recommended method (85.3%). With regards to preconception planning, 50% of respondents routinely had a preconception drug level prior to pregnancy. A significant proportion, 44.9%, reported not communicating a neurology-informed birth plan to obstetrical health practitioners. The majority recommended breastfeeding for WWE on anti-seizure medications (92.3%) and regularly provided safety counselling for women in the postpartum period (84.6%). Overall, our study demonstrates that Canadian practice patterns conform reasonably well to existing evidence and guidelines, although important gaps in care exist.

Real-world practices for the care of women with epilepsy during pregnancy: A Canadian perspective. Epilepsy Behav 2023; 148:109468. [PMID: 37857032 DOI: 10.1016/j.yebeh.2023.109468] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/13/2023] [Accepted: 09/26/2023] [Indexed: 10/21/2023]
Abstract
OBJECTIVE Approximately 150,000 Canadian women live with epilepsy, a population that presents with unique challenges. Our objective was to capture demographic and real-world practice characteristics of Canadian healthcare professionals providing care for women with epilepsy (WWE) with specific focus on reproductive considerations to identify potential gaps in knowledge and care. METHODS A questionnaire developed by the Canadian League Against Epilepsy WWE workgroup was distributed to Canadian healthcare professionals from February 2021 to October 2022 to capture participant demographic characteristics and practice patterns in key areas of the reproductive cycle in WWE. RESULTS A total of 156 participants completed the questionnaire, most being physicians (81.4%), epilepsy specialists (69.0%), and those who cared for adult patients (86.5%), with a significant proportion based at an academic center (65.4%). The majority of participants counselled on folic acid supplementation (89.7%). Participants selected lamotrigine and levetiracetam most frequently for either focal or generalized epilepsies during pregnancy. Additionally, 85.9% performed therapeutic drug monitoring during pregnancy. Almost all practitioners always or often counseled WWE on valproic acid on the benefits of switching to a less teratogenic medication (96.2%). Some geographic variability in practice patterns was noted with valproic acid being one of the top three medications selected for patients with generalized epilepsies in Western regions, although participants in Eastern regions had brivaracetam more commonly included as one of their top three agents for this population. SIGNIFICANCE This is the first report of real-world Canadian practices in epilepsy care for women in pregnancy. Overall, our study reports that Canadian practice patterns conform well to current evidence and best-practice guidelines. Important variations in antiseizure medication selection across different regions were identified.

Abstract
PURPOSE/OBJECTIVE(S) A reliable method of identifying clinically node negative bladder cancer patients at greater risk of developing lymph node metastasis and may require intensified therapy is needed. The purpose of this study was to create a nomogram to quantify the risk for regional lymphatic involvement in non-metastatic muscle invasive bladder cancer. MATERIALS/METHODS Usingthe National Cancer Database, patients with clinical T2-4N0M0 urothelial carcinoma of the bladder between the years of 2004 - 2020 were selected. All patients completed multiagent chemotherapy followed by surgery for pathologic nodal staging to determine presence or absence of nodal disease. No neoadjuvant radiation therapy was allowed and patients with history of prior malignancies were excluded. Following a 70:30 training to testing data split, baseline variables were assessed using univariate logistic regression. Variables were selected for inclusion in the multivariate logistic regression model using a combination of previously reported findings in the literature and/or if found to have a p-value < 0.05 on univariate analysis. A nomogram was constructed using this final model with assessment using calibration plots and the area under the receiver operating characteristics curve (AUC), respectively. An empiric cut point was chosen at 95% sensitivity to identify patients at "high" and "low" risk for pathologic nodal disease with overall assessment in both cohorts using chi-square. RESULTS A total of 6194patients were identified for study with a median age of 65 years (IQR = 58 - 71 years). Most patients were male (68.0%) with T2 disease (81.2%). The final multivariate model included age at time of diagnosis (OR = 0.99; 95% CI = 0.99 - 1.00; p = 0.172), time from diagnosis to initiation of chemotherapy (OR = 1.00; 95% CI = 1.00 - 1.01; p = 0.005), papillary histology (OR = 0.85; 95% CI = 0.72 - 1.01; p = 0.068), and clinical T stage (Table 1). Model calibration demonstrated excellent goodness-of-fit with good discrimination (AUC = 0.644). Within the training data, high risk patients were seen to have a twofold increase in pathologic nodal disease (N = 835/3924, 21.2%) when compared to those identified as low risk (N = 38/347, 9.9%) (p < 0.001). Validation within the testing data set demonstrated similar results with pathologic node rates of 22.8% and 7.8% for high- and low-risk patients, respectively (AUC = 0.645, p < 0.001). CONCLUSION This study demonstrates a clinically applicable risk stratification tool for identifying patients at risk for developing lymphadenopathy in T2-4 bladder cancer and may help guide future research in selecting patients eligible for escalation of therapy. Future studies should aim to externally validate this tool within prospective cohorts, and seek to determine if this nomogram may provide further prognostic utility.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to determine if a previously developed nomogram predictive of developing pathologic lymph node metastasis after multiagent chemotherapy for clinical node-negative muscle invasive bladder cancer may also prognosticate overall survival (OS) in patients treated with definitive chemoradiotherapy (CRT). MATERIALS/METHODS Using the National Cancer Database, we identified all patients with cN0 muscle invasive urothelial carcinoma of the bladder treated with definitive CRT from 2004 to 2020. Patient probability of occult nodal disease was assessed using a previous nomogram developed from those treated with multiagent chemotherapy alone followed by pathologic nodal assessment. Following a 70:30 training and testing data split, variables were assessed for association with OS using the log-rank test, with those with p < 0.05 deemed eligible for inclusion within a multivariate Cox proportional hazards model. Patients were then stratified as high-, medium-, or low-risk for death using the hazard function's prognostic index. The proportional hazards assumption was checked using Schoenfeld residuals and discrimination assessed using dynamic area under the receiver operating characteristics curves (AUC). Validation was assessed within the testing and a retrospectively collected institutional cohort of 15 patients treated from 2014 - 2020 with CRT. RESULTS A total of 1047 patients were identified for this study with median age of 78 years (IQR = 70-83 years) and follow-up of 31.3 months (IQR = 16.0 - 56.6 months). Cox analysis revealed patient age (HR = 1.03; 95% CI = 1.02 - 1.04; p < 0.001), Charlson-Deyo Score, and predicted probability of developing future lymphadenopathy (HR = 4.47; 95% CI = 1.83 - 10.93; p = 0.001) were significantly associated with OS. Median OS for those identified as high, medium, and low risk for death on Cox analysis was 34.2 months (IQR = 21.3 - 40.6 months), 38.9 months (IQR = 31.4 - 47.2 months), and 77.8 months (IQR = 56.1 - 100.3 months), respectively (AUC range = 0.615 - 0.870) (p < 0.001). Similar discrimination was seen within the testing cohort as well with significant differences between median OS across each group (AUC range = 0.580 - 0.726) (p < 0.001). Notably, among patients within the institutional cohort, only one patient stratified as high (N = 1/2; 50.0%) or medium risk (N = 0/5; 0.0%) remained alive at time of final follow-up, whereas 88.9% (N = 7/8) of low-risk patients survived (p = 0.051). Similarly, significant differences in OS were again seen between risk groups, with a median OS of 51.3 months and 19.9 months for high- and medium-risk patients, respectively, while median OS for low-risk patients was not reached (p = 0.006). CONCLUSION This study demonstrates the prognostic utility of a previously reported nomogram in predictions of OS. Investigation is warranted to explore how radiation and chemotherapy may offset worse OS in those at high risk for occult nodal disease progression.

Ipsilateral preictal alpha rhythm attenuation (IPARA): An EEG sign of side of seizure onset in temporal lobe epilepsy. Seizure 2023; 110:194-202. [PMID: 37423165 DOI: 10.1016/j.seizure.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 06/30/2023] [Accepted: 07/02/2023] [Indexed: 07/11/2023] Open
Abstract
PURPOSE Identification of the seizure onset zone is critically important for outlining the surgical plan in the treatment of pharmacoresistant focal epilepsy. In patients with temporal lobe epilepsy (TLE), bilateral ictal scalp EEG changes frequently occur and can make lateralization of the seizure onset zone difficult. We investigated the incidence and clinical utility of unilateral preictal alpha rhythm attenuation as a lateralizing sign of seizure onset in TLE. METHODS Scalp EEG recordings of the seizures acquired during presurgical video-EEG monitoring of 57 consecutive patients with TLE were reviewed retrospectively. Included patients had interictal baseline recordings demonstrating symmetrical posterior alpha rhythm and seizures occurring during wakefulness. RESULTS We identified a total of 649 seizures in the 57 patients, of which 448 seizures in 53 patients fulfilled the inclusion criteria. Among the 53 included patients, 7 patients (13.2%) exhibited a distinct attenuation of the posterior alpha rhythm prior to the first ictal EEG changes, in 26 of 112 (23.2%) included seizures. Preictal alpha rhythm attenuation in these seizures was ipsilateral to the ultimately determined side of seizure onset (based on video-EEG or intracranial EEG findings) in 22 (84.6%) of these seizures and bilateral in 4 (15.4%), and occurred on average 5.9 ± 2.6 s prior to ictal EEG onsets. CONCLUSION Our findings suggest that in some patients with TLE lateralized preictal attenuation of the posterior alpha rhythm may be a useful indicator of side of seizure onset, presumably due to early disruption of thalamo-temporo-occipital network function, likely mediated through the thalamus.

Abstract
Few dietary patterns are related to reduce the Bladder Cancer (BC) risk. One of the well-known dietary patterns is the Mediterranean diet (MD). This case-control study investigated the association between MD and the odds of BC among Iranian population. The present case-control study was performed on 103 eligible cases and 200 controls age 45 to 92 years. Diet of participants was assessed by a validated 168-item food frequency questionnaire (FFQ). Adherence to MD was measured by Mediterranean-Style Dietary Pattern Score (MSDPS). Multivariate logistic regression was used to estimate the relationship between MSDPS and risk of BC. After controlling for potential confounders, a negative association was observed between MSDPS and risk of BC (OR = 0.22; 95%CI = 0.09-0.52; p trend = 0.001). Furthermore, significant negative associations were observed for dairy, fish and other seafood, whole-grain, bread intake and risk of BC (p for trend < 0.05). In contrast, the risk of BC increased for high intake of poultry (OR = 1.09; 95%CI = 1.03-1.15; p trend = 0.003), sweets (OR = 1.24; 95%CI = 1.03-1.48; p trend = 0.018) and egg (p for trend = 0.01). Our results suggested that dietary habit in concordance with the principles of the Mediterranean dietary pattern may protect against BC.

Major Dietary Patterns in Association with the Grades of Nonalcoholic Fatty Liver Disease in Newly Diagnosed Patients Living in North of Iran. Int J Prev Med 2022; 13:121. [PMID: 36276888 PMCID: PMC9580550 DOI: 10.4103/ijpvm.ijpvm_660_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 08/22/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Evidence suggests that dietary pattern is related to incidence and grades of nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the relationship between major dietary patterns and hepatic histologic features of newly diagnosed patients with NAFLD. METHODS This cross-sectional study included 260 newly diagnosed NAFLD patients. Hepatic fibrosis and steatosis were diagnosed using Fibroscan. Dietary information was obtained using a validated 168-item semiquantitative food frequency questionnaire. The association between dietary patterns and odds ratio of the grade of fibrosis and steatosis was examined by multinomial logistic regression. RESULTS The mean ± SD age participant was 46.53 ± 11.71 years. Fifty-seven percent of the participants were women. Two major dietary patterns were recognized: "Western dietary pattern" and "Mediterranean dietary pattern." After adjustment for various confounders, adherence to the two extracted dietary patterns was not associated with odds of fibrosis and steatosis (P > 0.05). However, P was not significant. Patients in the second quartile of the Mediterranean dietary pattern had a higher risk for being in the F1 grade compared to those in the reference group in the crude and adjusted model. CONCLUSIONS The major dietary patterns of NAFLD patients living in Gilan were not related to the severity of their disease. More precise study design such as cohort or interventional studies is suggested to reveal the strength of this study findings.

Relationship between diet quality and depression among Iranian older adults in Tehran. BMC Geriatr 2022; 22:708. [PMID: 36028815 PMCID: PMC9419352 DOI: 10.1186/s12877-022-03380-1] [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: 01/02/2022] [Accepted: 08/12/2022] [Indexed: 11/26/2022] Open
Abstract
Background Depression is one of the prevalent mental disorders that is common in older ages. Evidence suggests that dietary intake status may potentially be associated with depression. However, this association has not been well studied in older adults, and the nature of the association remains unclear. This study aimed to investigate the association between diet quality and depression in free-living older adults living in Tehran city. Methods This cross-sectional study was conducted on 583 older adults (279 men and 304 women) aged 60 to 80 years living in Tehran city, selected by the systematic cluster sampling method. Individuals' dietary intake was determined by two non-consecutive 24-h dietary recalls, and diet quality was assessed calculating score of Healthy Eating Index-2015 (HEI-2015). The validated short form of the Geriatric Depression Scale (GDS-11) was used to assess depression status. A logistic regression model was used to assess the chance of depression across tertiles of HEI-2015 score. Results The point prevalence of depression was 22.5%, which was significantly higher in women (91 (69.5%) women vs. 40 (30.5%) men). A higher percentage of seniors at the higher tertile of HEI score were women, belonged to Fars ethnicity and had a higher score of activity of daily living (ADL). After adjustment for all potential confounders, the trend of depression chance was significantly decreased in those with higher HEI-2015 scores (p-for trend < 0.05). Conclusion Higher quality of diet was associated with a lower possibility of depression in the studied participants. Further studies are required to investigate the possible causal relationship.

Abstract
PURPOSE Preoperative stereotactic radiosurgery (SRS) of brain metastases may achieve similar local control and better leptomeningeal control rates than postoperative fractionated stereotactic radiotherapy (FSRT) in patients treated with elective metastasectomy. To plan a multicentre trial of preoperative SRS compared with postoperative FSRT, a survey of experts was conducted to determine current practice. METHODS A survey with 15 questions was distributed to the DEGRO Radiosurgery and Stereotactic Radiotherapy Working Group. Participants were asked under what circumstances they offered SRS, FSRT, partial and/or whole brain radiotherapy before or after resection of a brain metastasis, as well as the feasibility of preoperative stereotactic radiosurgery and neurosurgical resection within 6 days. RESULTS Of 25 participants from 24 centres, 22 completed 100% of the questions. 24 respondents were radiation oncologists and 1 was a neurosurgeon. All 24 centres have one or more dedicated radiosurgery platform and all offer postoperative FSRT. Preoperative SRS is offered by 4/24 (16.7%) centres, and 9/24 (37.5%) sometimes recommend single-fraction postoperative SRS. Partial brain irradiation is offered by 8/24 (33.3%) centres and 12/24 (50%) occasionally recommend whole-brain irradiation. Two centres are participating in clinical trials of preoperative SRS. SRS techniques and fractionation varied between centres. CONCLUSION All responding centres currently offer postoperative FSRT after brain metastasectomy. Approximately one third offer single-fraction postoperative SRS and four already perform preoperative SRS. With regard to potential co-investigators, 18 were identified for the PREOP‑2 multicentre trial, which will randomise between preoperative SRS and postoperative FSRT.

Abstract
OBJECTIVE The Dietary Approaches to Stop Hypertension (DASH) diet is rich in recommended foods that are inversely associated with bladder cancer (BC) risk. The main objective of this study was to investigate the association between adherence to DASH diet and the risk of BC among Iranian adults. METHOD This study included 103 BC cases and 200 controls. The controls were patients who were hospitalised for acute non-neoplastic diseases. DASH scores were computed from dietary intake assessed by a previously validated food frequency questionnaire. RESULTS After controlling for potential confounders, participants in the highest quintile of DASH (compared to the lowest quintile) had 84% lower BC risk (OR = 0.16; 95%CI: 0.05-0.45; p trend = 0.001). Among the DASH components, significant negative associations were observed between low fat dairy and whole grains intake with BC (p value < 0.05). A positive relation was observed for sodium, nuts and legumes, and sweetened beverages (p value < 0.05). CONCLUSION The results of this study suggested that adherence to DASH might be associated with reduced risk of BC. These findings could be used to develop evidence-based recommendations for the prevention of BC.

Abstract
Colorectal cancer is the fourth leading cause of cancer-related deaths that has significantly increased over the past three decades. New therapeutic approaches, such as oncolytic viruses, have become very imperative recently to destroy cancer cells. The use of mesenchymal stem cells (MSCs) secretome that is produced in response to variant conditions involves different paracrine molecules secretion that has therapeutic potential in several chronic diseases. Mesenchymal stem cells and their derivatives are employed as regenerative medicine; nevertheless, there is ambiguity in the function of these cells in the control of malignancy. This study aimed to examine the apoptotic effect of secretomes derived from MSCs affected by encompassing oncolytic reoviruses. Mesenchymal stem cells were cultured after separation from abdominal adipose tissue of BALB/c mice. After three passages, the cells were infected by reovirus at the multiplicity of infection of 1 plaque-forming unit per cell. Uninfected and infected secretomes with reovirus were collected separately. The colorectal cancer CT26 cells were confronted with uninfected secretome, infected secretions, reovirus as a positive control, and Dulbecco's Modified Eagle Medium/High Glucose as negative control separately. Finally, apoptosis and necrosis were evaluated by flow cytometry. The infected secretome with reovirus was capable to induce apoptosis more than the uninfected secretome in CT26. However, the supernatant of reovirus infected cells was more capable to induce cell death, in comparison to the infected secretome. Infected MSCs with oncolytic reovirus produced a type of condition media that enhanced apoptosis induction and could have a therapeutic effect on cancer cells. Nonetheless, tumoral cells confronted with the oncolytic reovirus showed more capability in inducing apoptosis in CT26 cells. As a result, the use of oncolytic virus and infected secretome are more effective than uninfected secretome in inducing apoptosis.

[PMID: 35936548 PMCID: PMC9288409 DOI: 10.18502/ijph.v51i4.9254] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 04/23/2021] [Indexed: 11/27/2022]
Abstract
Background: Socioeconomic factors are major determinants of health and food consumption. The aim of the present study was assessing the changes in energy and different food groups consumption related to the socioeconomic status of Iranian households. Methods: In this repeated cross-sectional study, 717432 households data from the Households Income and Expenditure Survey (HIES) conducted yearly by the Statistical Centre of Iran (SCI) from 1991 to 2017 was used. The food consumption outcome was modeled as a function of household head age, household head age-squared, socioeconomic variables, household size, place of residence, and household‘s head sex. Principle Component Analysis (PCA) was used to extract a socioeconomic status variable based on the educational, occupational, and income status of households. A cross-classified random effects modeling (CCREM) specifications of Hierarchical Age-Period-Cohort (HAPC) models was used in the present study. Results: In the present study, by moving to the higher quartiles of SES had higher calorie intake increased. There was a positive relationship between “Vegetables”, “Fruits”, “Dairy”, “Meat, Poultry, Fish, Eggs, Legumes, and Nuts” and “Fats, Oils, Sugars, and Sweets” with socioeconomic statues category. In the case of “Bread, Cereal, Rice, and Pasta”, there was a reverse relationship, and lower SES quartile consumed a higher amount of this food group. Conclusion: Lower income, education, and occupational status in lower SES quartile groups lead to lower calorie consumption and higher consumption of “Bread, Cereal, Rice, and Pasta” food group, which had lower energy cost compared to the other food groups.

Maternal dietary diversity and nutritional adequacy in relation with anthropometric measurements of newborns at birth: a cohort study in Tehran city. BMC Pediatr 2022; 22:129. [PMID: 35279127 PMCID: PMC8917625 DOI: 10.1186/s12887-021-03102-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 12/28/2021] [Indexed: 11/30/2022] Open
Abstract
Background Maternal dietary intake during pregnancy plays an important role in fetal development and birth outcomes. The aim of the present study was to determine maternal dietary diversity and Nutritional adequacy in relation with anthropometric measurements of newborn at birth as a cohort study in Tehran city. Methods This prospective cohort study, was conducted by participation of 585 pregnant women referred to public health centers and hospitals covered by Shahid Beheshti, Tehran and Iran Universities in Tehran City. Using face-to-face interviews, general characteristics were obtained by questionnaire. Pre-pregnancy dietary intake was measured by a 168-item semi-quantitative food frequency questionnaire at the first visit, and dietary intake during pregnancy was measured by 2 non-consecutive 24-h food recall (one holiday and one regular day) at 31–34 weeks. Maternal height and weight were measured using standard tools and protocol at the first visit, and maternal weight at the end of pregnancy and data related to neonatal anthropometric indices were collected from mothers and neonates health records in the Sib electrical system. By applying SPSS software (version 23) the association was analyzed by linear regression with adjusting for confounding factors. P-value< 0.05 was considered as significant. Results Mean ± standard deviation of body mass index (BMI) of pre-pregnancy, pregnancy weight gain, BMI for age z-score (BAZ) at birth of infants were 24.52 ± 4.12, 12.16 ± 6.85 kg and − 0.61 ± 1.48, respectively. Mean ± SD of the Dietary Diversity Score (DDS) and Mean Adequacy Ratio (MAR) before and during pregnancy were 5.31 ± 1.11, vs.5.23 ± 1.42 and 289.85 ± 113.12 vs. 371.07 ± 197.28, respectively. After adjusting for confounding factors DDS in the third trimester of pregnancy was inversely correlated with WAZ (B = -0.16, 95% CI = - 0.23_0.30) and BAZ (B = − 0.24, 95% CI = - 0.06_0. 42) at birth, MAR of pre-pregnancy (B = − 0.001, 95% CI = - 0.002_0.00) and in the third trimester of pregnancy (B = − 0.18, 95% CI = - 0.35_0.004) were negatively associated with WAZ at birth. Conclusion The findings showed that maternal nutritional status (dietary diversity and nutritional adequacy) before and during pregnancy were correlated with neonatal anthropometric indices at birth.

Abstract
Bladder cancer (BC) is the ninth most common cancer in the world. Dietary patterns and diet quality could reduce exposure to carcinogenic factors postulated to increase the risk of BC. The main objective of this study was to investigate the associations of Recommended Food Score (RFS) and Non-Recommended Food Score (n-RFS) with the risk of BC among Iranian adults. This is a hospital-based case-control study, conducted at three referral hospitals in Tehran, the capital of Iran. Cases consisted of 103 histologically confirmed BC patients, aged greater than 45 years. Age-matched controls (n = 200) were selected from the same hospital where cases were recruited. Controls were patients with non-neoplastic diseases that are not related to smoking, or long-term diet modification. Dietary intake was assessed by a 168-item Food Frequency Questionnaire (FFQ), which was validated in Iran. Logistic regression tests were used to estimate the relationship between RFS and n-RFS with BC. The risk of BC decreased by 69% (OR = 0.31; 95% CI:0.13-0.71) among participants belonging to the highest compared with the lowest quartile of RFS. After adjusting for age, sex, smoking, and total energy, a significant inverse trend was observed between the risk of BC and quartile of RFS. Regarding the n-RFS, also expressed as quartiles, subjects in the fourth quartile were at 2.7 times higher risk of having BC compared to participants in the first quartile (OR = 2.7; 95%CI: 1.07-6.78). The findings of this study suggested that, adherence to RFS decreased the risk of BC. Additionally, a higher score of n-RFS may lead to an increased risk of BC. These findings could be used to develop evidence-based recommendations for the prevention of BC in Iran.

Abstract
BACKGROUND Dietary supplements (DSs) use have become a growing trend worldwide, and it may be affected by demographic and sociocultural factors. Some people use supplements with the thought that they can improve their health, reduce symptoms and prevent disease. The aim of the present study was to define the frequency of DS use and its association with socioeconomic factors among participants with selected main non-communicable chronic diseases (NCDs) (diabetes, cardiovascular disease (CVD), hypertension (HTN), cancers, and obesity in the north of Iran. METHODS This large cross-sectional study was conducted as a part of the PERSIAN Guilan cohort study. Supplement use during last year and its type, demographic factors, socioeconomic status, lifestyle habits were asked by face-to-face interview. The history of chronic disease was defined by a trained team. Data were analyzed using SPSS. The chance of supplement use according to demographic, socioeconomic, and lifestyle variables and history of chronic disease was analyzed by logistic regression. RESULTS 10,520 men and women aged 35-70 years in Some'e Sara County (including urban regions and 39 villages) were studied. About 25% of participants consumed DSs. The highest consumption of DS was calcium/vitamin D (11.1%), ferrous sulfate (8.8%), and vitamin D pearl or ampoule (7.7%). The highest percent of the history of chronic disease was central obesity (62.7%), HTN (43.2%), and general obesity (32.7), respectively. After adjustment for confounders, those with female gender, the highest age ranges (55-65 and > 65 years), high academic education, living in urban regions, and good economic status were more likely to be DSs consumers; however, married and smoker subjects were more likely to consume DS. Participants who had a history of diabetes, HTN, CVD, Obesity, and Central Obesity were more likely to intake DS in comparison with healthy subjects. CONCLUSION This study showed that a quarter of the participants were DS users. Female sex, older age groups, and higher educated participants, and among chronic disease, patients with HTN, CVD, and diabetes were more likely to be users of any DS.

Abstract
Destructive outcomes of coronavirus pandemic call for medical research which can report all of the influential agents not only for the treatment of the disease but also preventing its severe impacts on the societal health in the most efficient manner. Zinc plays an integral role in the function of cellular enzymes and transcription factors. Owing to its anti-inflammatory and cellular immunity regulation activity, zinc is regarded to be effective on strengthening the immune system. Its crucial antiviral effects have long been established as well. Studies suggest that low serum zinc level predisposes the patient to severe COVID-19 infection, which makes patient’s zinc profile a potential determinant of prognosis and severity of this disease. Furthermore, zinc supplementation has indicated promising outcomes of coronavirus infection management. Zinc modulates cell-mediated immunity and participates in the killing of microorganisms in cytotoxic immune cells. Zn2 + has anti-inflammatory effects by inhibiting IL-6 production. Although there is still not enough evidence, it seems that zinc could be a promising supplementary treatment for COVID-19 especially in zinc-deficient patients. The aim of this review is to clarify the role of zinc in pathogenesis and therapy of COVID-19 in detail.

Abstract
BACKGROUND The aim of the present study was assessing the changes in Iranian household food basket. The Households Income and Expenditure Survey (HIES) data of 717,432 of Iranian households from 1991 to 2017 were used in this repeated cross-sectional study. METHODS A cross-classified random-effects modeling (CCREM) specifications of hierarchical age-period-cohort (HAPC) in two models, one without controlling for the effects of key individual characteristics, namely socioeconomic status; household size; place; and household head sex, and another one with controlling for the effect of mentioned variables, was used in the present study. RESULTS The present study showed that the equivalent to an adult male daily consumption of "total calorie" (P value = 0.0001) and "fats, oils, sugars, and sweets" (P value = 0.0002) had an increasing trend from 1991 to 2004 and a decreasing trend from 2005 to 2017 among Iranian households. The daily consumption of "bread, cereal, rice, and pasta" (P value = 0.0001) had a decreasing and "fruits" (P value = 0.0002) had a rising trend during periods. After an increasing trend for the "meat, poultry, fish, eggs, legumes, and nuts" (P value = 0.0002) and "vegetable" (P value=<0.0001) by 2004, there was a decreasing trend from 2004 to 2017, but the share of them in the total calorie consumption increased. The "dairy" (P value = 0.0002) consumption had a decreasing trend in recent years. CONCLUSIONS Iranian household food basket, during these years, had significant changes that some of them (increase in the share of the vegetables and fruits in the total calorie intake) are positive and some of them are negative (decrease in the consumption of dairy).

Abstract
BACKGROUND Cardiovascular disease (CVD) includes a group of heart and coronary disorders that can be prevented by promoting the quality of an individual’s diet. The Recommended Food Score (RFS) and Healthy Nordic Food Index (HNFI) are suggested for the assessment of diet quality and as indicators of dietary exposures related to disease. The aim of this study was to systematically review the association of the RFS and the HNFI with CVD and stroke. METHODS Articles were identified by searching PubMed, Google Scholar, and ScienceDirect using relevant keywords for articles published until December 2018. The inclusion criteria were all types of observational studies and English language. Non-English and irrelevant studies were excluded. RESULTS In total, 14 studies met the inclusion criteria. Of the 7 studies that investigated the association between the RFS and CVD, 6 articles showed a lower risk of CVD in individuals who obtained a higher RFS and lower non-RFS (n-RFS) score. Studies that investigated the relation between RFS and stroke (n = 2) showed that achieving a higher RFS could decrease the risk of stroke. Of the 4 studies that assessed the relationship between HNFI and CVD, 3 showed that adherence to HNFI were related with lower risk of CVD/stroke. However, one study did not show any relationship. CONCLUSION A higher RFS may result in a decrease in the risk of CVD and stroke. Due to the inconsistency of the findings related to HNFI, more studies are needed to approve the negative relationship between HNFI and CVD.

Abstract
Background: Abdominal obesity (AO) is a global health problem. Although few studies indicated that Nordic diet (ND) was associated with AO, no evidence exists for the association between ND and AO outside the Nordic countries. In this study, we aimed to determine the relationship of ND with AO and anthropometric indices among Iranian women.
Methods: In this cross-sectional study, we evaluated anthropometric indices and usual dietary intakes of 294 Iranian women aged 20-50 years. We defined AO as waist circumference (WC) ≥ 88 cm and WC ≥ 90 (according to Iranian criteria). Association between qualitative variables and health eating index-nordic nutrition recommendation (HEI-NNR) score was determined using Chi-square and Mann–Whitney tests. The relationship of HEI-NNR score with AO was analyzed by a logistic regression model after adjusting the effect of confounders.
Results: The mean of HEI-NNR score was significantly higher in overweight and obese participants than participants without overweight (P = 0.04). No linear trend was found for body mass index, WC, and waist to hip ratio (WHR) through the HEI-NNR score even after adjustment for confounders. A significant positive association was found among HEI-NNR score, overweight, and obesity (OR = 1.85, 95%CI = 1.15-2.96, P = 0.01). However, the association did not remain significant after adjusting for the confounders.
Conclusion: Adherence to the ND was not associated with AO and anthropometric measurement among Iranian women. Future evidences from RCT and prospective cohort studies are needed to confirm these findings.

Abstract
BACKGROUND Studying entire dietary patterns is a promising alternative approach to overcome limitations of the single food or nutrient approach. We evaluated the relationship between the scores of 4 established Dietary Approaches to Stop Hypertension (DASH) diet indexes and breast cancer risk among Iranian women. METHODS This case-control study was carried out on 408 eligible women (136 cases and 272 hospital-based controls). A validated 168 item semi-quantitative food frequency questionnaire was used for assessing usual dietary intakes. DASH index scores were generated based on predefined algorithms for each of the 4 previously described indexes (Dixon's, Mellen's, Fung's and Günther's DASH diet index). Unconditional logistic regression analysis was performed to estimate odds ratio (OR) and 95% confidence intervals (CIs) for score categories or quintiles of DASH diet indexes and breast cancer risk in multivariate adjusted models. RESULTS Women in the highest categories of the Mellen's and Günther's scores had lower odds of breast cancer than those in the lowest quintiles (Mellen's OR:0.50; 95% CI:0.62-0.97; P-trend:0.02; Günther's OR:0.48; 95% CI:0.25-0.93; P-trend:0.05). However, no significant associations were found between Dixon's and Fung's DASH score and breast cancer risk. Modification by menopausal status revealed that breast cancer risk was only reduced in postmenopausal women with higher scores on Mellen's index (OR:0.24; 95% CI:0.08-0.68; P-trend:0.04). CONCLUSION A greater adherence to 2 of the 4 DASH indexes (Mellen's and Günther's indexes) was associated with decreased risk of breast cancer.

Abstract
Aim: Cancer is the second leading cause of death in the world. About one third of deaths from cancer are due to the five behavioral and dietary risk factors e.g., high body mass index, low fruit and vegetable consumption, lack of physical activity, tobacco use, and alcohol use. The aim of this study is to review systematically the association of Recommended Food Score (RFS) and the Healthy Nordic Food Index (HNFI) with cancer.Method: Literature search conducted using electronic database PubMed, Google scholar, Science direct for the period of 2011 until January 2020 also reference list of the included studies.Results: Nine studies were met inclusion criteria. Two studies that investigated about RFS showed no significant association between RFS and breast cancer and colorectal cancer survival. Two out of three studies aboutthe HNFI and colorectal cancer observed that adherence to the HNFI might decrease colorectal cancer incidence and improve colorectal cancer survival. In addition, two out of three studies showed adherence to the HNFI could decrease cancer mortality.Conclusion: Adherence to the HNFI might decrease the risk of colorectal cancer incidence. It is suggested more studies about between RFS and THE HNFI with other kind of cancers.

Abstract
OBJECTIVES To systematically review and identify food frequency questionnaires (FFQs) developed for the Iranian population and their validation and reproducibility in order to determine possible research gaps and needs. METHODS Studies were selected by searching for relevant keywords in the PubMed, Scopus, Science Direct, Google Scholar, SID, and Iranmedex databases, unpublished data, and theses in November 2016 (updated in September 2019). All English-language and Persian-language papers were included. Duplicates, articles with unrelated content, and articles only containing a protocol were excluded. The FFQs were categorized based on: (1) number of food items in to short (≤80 items) and long (>80 items) and; (2) the aim of the FFQ to explore total consumption pattern/nutrients (general) or to detect specific nutrient(s)/food group(s) (specialized). RESULTS Sixteen reasonably validated questionnaires were identified. However, only 13 presented a reproducibility assessment. Ten FFQs were categorized as general (7 long, 3 short) and 6 as specialized (3 long, 3 short). The correlation coefficients for nutrient intake between dietary records or recalls and FFQs were 0.07-0.82 for long (general: 0.07-0.82 and specialized: 0.26-0.67) and 0.20-0.67 for short (general: 0.24-0.54 and specialized: 0.20-0.42) FFQs. Long FFQs showed higher validity and reproducibility than short FFQs. Reproducibility of FFQs was acceptable (0.32-0.89). The strongest correlations were reported by studies with shorter intervals between FFQs. CONCLUSIONS FFQs designed for the Iranian population appear to be appropriate tools for dietary assessment. Despite their acceptable reproducibility, their validity for assessing specific nutrients and their applicability for populations other than those they were developed for may be questionable.

Abstract
BACKGROUND This paper aims to assess different scenarios that reduce water use by following healthy diet recommendations. In this study, a food frequency questionnaire was used to assess the usual food intake of a sample of 723 individuals, aged 20-64 years, from Urmia, Iran. In order to calculate water use for production of food items, the water footprint method was applied. A linear programming technique was used to find a healthy diet with low blue water footprint in three scenarios. RESULTS The biggest decline in water use compared with real intake (57%) was found in scenario 1, where the model-generated consider energy intake equal to usual energy intake. In scenario 2, in which the proportion of each food group was allowed to be in accordance with the Iranian food pyramid, the reduction in water use was less than for scenario 1 (47%). In scenario 3, where the Recommended Dietary Allowance values were also added to the set of model restrictions, the water usage was 51% of the real diet. CONCLUSION A healthy diet with greater proportion of energy from fruit and dairy instead of a diet with high proportion of energy from 'meat-fish-poultry-eggs' and 'bread-cereal-rice-pasta' can supply all Recommended Dietary Allowances while reducing water use. © 2019 Society of Chemical Industry.

Abstract
Heterozygous mutations in syntaxin-binding protein 1 (STXBP1) gene are associated with early infantile epileptic encephalopathy 4 (EIEE4). This condition is characterized by epilepsy, developmental delay (DD), and various movement disorders. Herein, we will report 5 unrelated patients with different de novo mutations in STXBP1. In addition, we conducted an online survey through Facebook to identify the incidence of bruxism (BRX) in these patients. Four out of 5 patients (80%) presented with awake BRX (A-BRX). Bruxism was also reported in 81.4% (57/70) of the patients with STXBP1 encephalopathy through the online questionnaire. No consistent correlation was identified between the type of mutation and development of movement disorders or BRX. This is the first study to demonstrate A-BRX in patients with STXBP1 mutation. Given the role of STXBP1 in exocytosis of neurotransmitters and other manifestations of dopamine dysregulation in patients with STXBP1-EIEE4, we suggest that in patients with STXBP1 encephalopathy, A-BRX might be the result of the involvement of dopaminergic circuits.

Objective We aimed to delineate the distribution of periventricular nodular heterotopia (PNH) in patients with 22q11.2 microdeletion syndrome (22q11.2DS) and place this in the context of other genetic forms of PNH. Methods We retrospectively analyzed brain imaging and postmortem data available for adult patients with 22q11.2DS. We included only those with good quality MRI data (n = 29) in addition to two patients with PNH identified through postmortem studies. We also reviewed the pattern of PNH in all genetic conditions reported with this phenotype. Results Of the total seven patients (M = 4, F = 3; age: 19–61 years) identified to have PNH, six had a history of seizures, six had schizophrenia, six had variable levels of intellectual disability, and two had obsessive compulsive disorder. In all seven patients, the nodules were located over the dorsal pole of the frontal horn of the lateral ventricles. The nodules were small, noncontiguous, and ranged in number from 1 to 10 per individual. Our review identified 37 genetic conditions associated with PNH. With the cases reported here, 22q11.2DS becomes the fifth most commonly reported genetic condition, and the third most common copy number variation, associated with PNH. Interpretation The neuropsychiatric manifestations in our patients with PNH support other data indicating abnormal neurodevelopment as part of the pathogenesis of 22q11.2DS.The location and cellular characteristics of PNH in 22q11.2DS overlaps with a group of migrating postnatal interneurons termed Arc cells, although more research is needed to confirm that PNH in 22q11.2DS represents Arc cells arrested in their migratory pathway.

Abstract
BACKGROUND All government policies and programmes for food and nutrition security should include providing healthy food, as well as providing economic and social availability for all people. AIM This study aimed to analyse the current situation of Iranian food and nutrition security and establish a road map towards 2021. METHODS The applied methods were situation analysis and a mixed qualitative-quantitative method. The conceptual method used for developing this national document encompassed three areas: sustainable food supply, food safety and nutrition. RESULTS The outcomes of the Iranian food and nutrition security system in the past three decades include development of management infrastructure and improvement in food and nutrition security status. However, analysis of current programmes showed that there were some overlapping, intertwining and parallel works in the responsibilities of related organizations in the field of supervision of food safety (from production to supply). The national document produced as the outcome of this paper was communicated by the Iranian Ministry of Health in 2012 and has been running for 2 years. Selected ministries are responsible for implementation of 20 national programmes by the end of the 5th Economic, Social and Cultural Development Programme (2016-2011). The consensus of stakeholders by the end of the 6th Development Programme (2021) is to put all of the provinces in a safe or very safe situation in terms of food and nutrition security. CONCLUSION The most important challenge in establishing national documents is to make them operational. This aim was achieved by an intersectoral nutrition and food security working group, which produced a general memorandum of understanding with the main organizations, the media, universities and private sector.

Abstract
Exome sequencing has readily enabled the discovery of the genetic mutations responsible for a wide range of diseases. This success has been particularly remarkable in the severe epilepsies and other neurodevelopmental diseases for which rare, often de novo, mutations play a significant role in disease risk. Despite significant progress, the high genetic heterogeneity of these disorders often requires large sample sizes to identify a critical mass of individuals with disease-causing mutations in a single gene. By pooling genetic findings across multiple studies, we have identified six individuals with severe developmental delay (6/6), refractory seizures (5/6), and similar dysmorphic features (3/6), each harboring a de novo mutation in PPP3CA. PPP3CA encodes the alpha isoform of a subunit of calcineurin. Calcineurin encodes a calcium- and calmodulin-dependent serine/threonine protein phosphatase that plays a role in a wide range of biological processes, including being a key regulator of synaptic vesicle recycling at nerve terminals. Five individuals with de novo PPP3CA mutations were identified among 4,760 trio probands with neurodevelopmental diseases; this is highly unlikely to occur by chance (p = 1.2 × 10-8) given the size and mutability of the gene. Additionally, a sixth individual with a de novo mutation in PPP3CA was connected to this study through GeneMatcher. Based on these findings, we securely implicate PPP3CA in early-onset refractory epilepsy and further support the emerging role for synaptic dysregulation in epilepsy.

Abstract
Background Emerging evidence suggests that neighborhood characteristics can have direct and indirect effects on the weight status of the residents. Objectives To assess the relationship between general and central obesity and the neighborhood environment in two ethnic groups (Azeri Turks and Kurds) living in Urmia city, Northwestern Iran. Patients and Methods In this cross-sectional study, 723 participants (427 women and 296 men) aged 20 - 64 years from two ethnic groups (Azeri Turks, n = 445; Kurds, n = 278) were selected from 38 neighborhoods using a combination of cluster, random, and systematic sampling methods. Neighborhood characteristics were obtained by a validated 22-item neighborhood and a health observational checklist. General and central obesity were measured and evaluated using standard methods. Principal component analysis (PCA) was used to define the dominant neighborhood environment. The association of neighborhood characteristics with general and central obesity was analyzed by a logistic regression model. Results Three common neighborhood environments were identified: 1) modern-affluent, 2) central-high access and 3) marginal. These three factors explained 73.2% of the total variance. Overall, the participants living in a higher tertile of the central-high access neighborhoods had an increased chance of central obesity (OR = 1.63, 95% CI: 1.13 - 2.34). Azeri Turks living in the highest tertile of the modern-affluent neighborhoods had a significantly higher likelihood of having general obesity (OR = 2.49, 95% CI: 1.37 - 4.01). Adjustment for age, gender, marital status, socioeconomic status (SES), energy intake, and physical activity did not change the results. However, after adjustment for educational level, the association was not significant. Conclusions The findings point to a relationship between neighborhood characteristics and obesity only in the Azeri Turks. However, educational level was more important than neighborhood quality in predicting the risk of obesity

Abstract
Background: Adequate calcium intake may have a crucial role with regards to prevention of many chronic diseases, including hypertension, hypercholesterolemia, different types of cancer, obesity and osteoporosis. In children, sufficient calcium intake is especially important to support the accelerated growth spurt during the preteen and teenage years and to increase bone mineral mass to lay the foundation for older age. Objectives: This study aimed to assess daily calcium intake in school-age children to ensure whether they fulfill the FGP dairy serving recommendations, the recommended levels of daily calcium intake and to assess the relationship between dietary calcium intake and major bone health indicators. Patients and Methods: A total of 501 Iranian school-age children were randomly selected. Calcium intake was assessed using a semi-quantitative food frequency questionnaire. Bone health indicators were also assessed. Results: Dairy products contributed to 69.3% of the total calcium intake of the children. Daily adequate intake of calcium was achieved by 17.8% of children. Only 29.8% met the Food guide pyramid recommendations for dairy intake. Dietary calcium intake was not significantly correlated with serum calcium and other selected biochemical indicators of bone health. Conclusions: The need for planning appropriate nutrition strategies for overcoming inadequate calcium intake in school age children in the city of Tehran is inevitable.

Abstract
Inherited homocystinuria is a rare autosomal recessive aminoacidopathy which through early diagnosis can prevent its severe neurologic and vascular complications. Here we report a 9-year-old girl with homocystinuria, presenting with sequential symptoms of bilateral lens dislocation, skeletal complication, and eventually dystonia from the age of 4 years. Laboratory evaluation revealed severe high serum homocysteine level. Although pathophysiologically unexplained, evidence of deep white matter watershed infarct along with remarkable ipsilateral carotid stenosis was detected on the contralateral side of the dystonia in the neuroimaging. Treatment with high dose of pyridoxine relieved limb and gait dystonia significantly, while carotid stenosis remained unchanged. Therefore, homocysteine might have both structural and irreversible effect and functional and reversible impact that could be overcome even in late stages.

Abstract
Postoperative cerebellar hemorrhage or remote cerebellar hemorrhage is a rare complication occurring after supratentorial and spinal surgery. Although the mechanism remains unclear, previous reports implicate over drainage of cerebrospinal fluid as the predominant cause. We report a patient who underwent craniotomy for removal of meningioma. The hemorrhage manifested a few days postoperatively as a headache and transient loss of consciousness. Our patient recovered without further intervention with no major neurologic deficit. Early detection and awareness of this complication may help to avoid unnecessary measures.

Abstract
OBJECTIVES To determine the resting metabolic rate (RMR) in a sample of Iranian women, and to evaluate the validity of predictive equations for estimating RMR in normal and obese subjects. METHODS This cross-sectional study was conducted on a total of 187 healthy women aged 18-45 years. Anthropometric data were collected and subjects' RMR was measured by indirect calorimetry for 15 minutes following an overnight fast. RMR was also predicted using various types of formulas based on subjects' height, age, weight or fat-free mass. Body composition was estimated by bioelectric impedance analysis (BIA). RESULTS Measured RMR (mean ± SD) was found to be 1473 ± 296 kcal/day. The abbreviation formula overestimated RMR, while other formulas underestimated it. Harris-Benedict formula was valid among all BMI categories (normal weight, overweight, obese and morbidly obese). Two Schofield formulas were valid in normal weight, overweight and morbidly obese subjects; and Cunningham formula was valid only among overweight and obese women. Overweight and obese Iranian women had higher RMR in comparison with normal weight subjects (p<0.01); although after age and weight adjustment, the differences were not significant in any of the BMI categories. CONCLUSIONS The Harris-Benedict for mula provides a valid estimation of RMR at the group level in a range of normal-weight to morbidly obese Iranians. However, at the individual level, errors might be so high that using a measured value has to be preferred over an estimated value.

Abstract
OBJECTIVES Using a dietary pattern analysis method could provide more information about the nutritional etiology of chronic diseases such as obesity. The aim of this study is to determine the association between major dietary patterns and general and central obesity among adult women living in Tehran. MATERIALS AND METHODS A cross-sectional study was conducted in Tehran, Iran, with 460 women aged 20-50 y. Dietary intake in the previous year was collected by a semi-quantitative food frequency questionnaire. Weight, height and waist circumstance (WC) were measured with standard methods and body mass index (BMI) was calculated. General obesity was defined as BMI > or = 30 kg/m(2) and central obesity as WC > or = 88 cm. Factor analysis was used for identifying major dietary patterns. The association between major dietary patterns and general and central obesity were assessed by logistic regression analysis. RESULTS Two major dietary patterns were extracted: "Healthy" and "Unhealthy" dietary patterns. After adjusting for confounders, individuals in the highest quartile of the unhealthy dietary pattern score were more likely to have general (OR=7.33, 95% CI: 2.39-22.51) and central obesity (OR=4.99, 95% CI: 2.08-11.94), whereas, those in the upper quartile of healthy dietary pattern were less likely to have general (OR=0.38, 95% CI: 0.15-0.98) or central obesity (OR=0.33, 95% CI: 0.16-0.71). CONCLUSION Our data suggest that a dietary pattern rich in fruit, vegetables, low-fat dairy products and poultry might be negatively associated with obesity. Furthermore our data showed that a dietary pattern high in processed meats, soft drinks, sweets, refined grains, snacks and processed juice might be positively associated with obesity among women aged 20-50 y.

Abstract
OBJECTIVES To detect major dietary patterns and their relation with demographic, socioeconomic, and lifestyle factors in adult women living in Tehran, Iran. METHODS In a cross-sectional study, 460 women 20-50 y of age were selected by a stratified random-sampling method. Factor analysis was conducted to ascertain the major dietary patterns, and analysis of covariance was fitted to assess the relation between demographic, socioeconomic, and lifestyle variables and adherence to major dietary patterns. RESULTS Two major dietary patterns were extracted: healthy and unhealthy. After adjustment for confounders, age (b=0.31, P<0.01), university degree (b=0.85, P<0.01), housing size >20 m(2)/head (b=0.30, P<0.01), total family income US >$500/mo (b=0.25, P<0.05), physical activity (b=0.01, P<0.05), and history of hypertension (b=0.36, P<0.05) were positively associated and duration of residence in Tehran (b=-0.01, P<0.05) was negatively associated with a healthy dietary pattern. Conversely, ethnicity (Turk versus Fars; b=0.30, P<0.01) and smoking (b=0.64, P<0.01) were positively associated and age (b=-0.33, P<0.01) was negatively associated with an unhealthy dietary pattern. CONCLUSION Our findings support the association between demographic, socioeconomic, lifestyle factors and dietary patterns of the studied women. Therefore, it is suggested these factors should be considered in future studies on the association between dietary patterns and disease.
