Abstract
BACKGROUND Current evidence has demonstrated that patients with Multiple Sclerosis (MS) have dysbiotic gut microbiomes, and anti-inflammatory nutritional interventions can normalize this status. Therefore, we aimed to investigate the effects of dietary intervention in patients with progressive forms of MS. METHODS Seventy patients with three forms of progressive MS (primary-progressive, secondary-progressive, and progressive-relapsing) were randomly assigned into intervention (daily synbiotics capsule plus anti-inflammatory-antioxidant rich diet) or control (placebo capsule plus dietary recommendations) groups for four months. Faecal calprotectin level, Impact of Vision Impairment (IVI), Gastrointestinal Symptom Rating Scale (GSRS), and anthropometric measurements were evaluated at baseline and trial cessation. Analysis of covariance was conducted and adjusted for age, gender, education level, family history & duration of MS, type of progressive MS, type of main drug, and physical activity. RESULTS Sixty-nine participants were included in the final analysis (n of intervention = 34; n of control = 35). Synbiotics and dietary intervention significantly reduced Faecal calprotectin level after six months (110.5 ± 75.9-44.7 ± 49.3 ɥg/g, P < 0.001), and mean changes were statistically significant in comparison with control group. However, intervention did not elicit any change in the anthropometric measurements. CONCLUSION Synbiotics supplementation and adherence to an anti-inflammatory-antioxidant-rich diet reduced intestinal inflammation and improved clinical manifestations in progressive forms of MS.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20141108019853N7..

Abstract
BACKGROUND AND PURPOSE There is growing evidence that dietary modification can improve clinical manifestations in multiple sclerosis (MS) patients. This study aimed to assess the impact of synbiotics and anti-inflammatory-antioxidant-rich diet on fatigue, pain, gut and bladder status, and sexual function in patients with progressive forms of MS. MATERIALS AND METHODS In this single-center, single-blind, randomized, controlled clinical trial, seventy participants with three forms of progressive MS (primary-progressive, secondary-progressive, and progressive-relapsing) were randomly assigned to receive either synbiotics supplement and anti-inflammatory-antioxidant-rich diet or a placebo along with their usual diet for a duration of four months. Modified fatigue impact scale (MFIS), global pain scale (GPS), bladder control scale (BLCS), bowel control scale (BWCS), and sexual satisfaction scale (SSS) were assessed at baseline and at the end of the trial. RESULTS Sixty-nine participants successfully completed the trial, resulting in a 98% adherence rate to the diet, and no reports of serious side effects. Significant mean changes were observed in fatigue (Δ for experimental group = -10.5 ± 10.8 vs. Δ for control group = -0.08 ± 4.1; P < 0.001), pain (-14.1 ± 19.0 vs. 0.9 ± 10.3; P < 0.001), bladder (-0.76 ± 2.1 vs. 0.3 ± 1.1; P = 0.013) and bowel (-6.6 ± 3.2 vs. -0.05 ± 2.3; P < 0.001) control, as well as sexual function (-1.0 ± 2.3 vs. 0.51 ± 0.21; P < 0.001). CONCLUSION The anti-inflammatory-antioxidant-rich diet and synbiotics co-supplementation demonstrated improvements in fatigue, pain, sexual function, and bowel/bladder status among patients with progressive MS.

Abstract
BACKGROUND Probiotics can improve immune function leading to the prevention and management of viral infections like SARS-CoV-2 infection (COVID-19 disease). METHODS We searched PubMed, EMBASE, Google Scholar, Science Direct, Scopus, and Web of Science up to May 2020 to identify interventional & observational studies documenting the effects of probiotics on incidence, severity, duration, and other clinical manifestations of viral infections, especially SARS-CoV-2-induced. RESULTS From a total of 91 records, 24 studies were obtained and classified into three domains based on the efficacy of probiotics on 1) shortening the period and severity of infections (n=9), 2) incidence (n=6), and 3) other clinical complications that may be followed by viral disorders (n=9). Identified probiotics have positive effects on the mentioned domains. CONCLUSION Based on the evidence, some probiotic strains may be useful in SARS-CoV-2 infection; randomized trials are needed to show the facts.

Abstract
BACKGROUND Human clinical trials that have investigated the effect of soy product consumption on adipokines have reported inconsistent results. Our objective was to elucidate the role of soy product consumption on adiponectin and leptin in adults through a systematic review and meta-analysis of available randomised placebo-controlled trials (RCTs). METHODS The systematic search included PubMed, Scopus, Web of Science, EmBase, Google Scholar and Cochrane database from inception to July 2020. Human clinical trials that reported the effect of soy product consumption on leptin and adiponectin were included. The pooled weighted mean difference (WMD) was calculated by the random-effects model. Heterogeneity, sensitivity analysis, and publication bias were reported using standard methods. Quality assessment was performed using Cochrane risk of bias assessment tool. RESULTS Overall, 13 RCTs with 824 participants were included in this meta-analysis. Our analysis showed that soy product consumption did not significantly affect leptin (WMD: 0.01 ng/mL; 95% CI, -0.16, 0.18; P = .88) and adiponectin (WMD: -0.09 ng/mL; 95% CI, -0.29, 0.12; P = .39) concentration in comparison with control. Furthermore, subgroup analysis indicated that the effect remained non-significant when analysed by study design, participant demographics and intervention characteristics. Based on the Cochrane Collaboration Risk of Bias tool, seven studies were considered good quality and six studies were fair. CONCLUSION The present systematic review and meta-analysis suggest that soy product consumption had no significant effect on leptin and adiponectin levels in adults. However, future larger and well-designed trials are still needed to further explore this research area and to address the heterogeneous study design used in the existing literature.

Abstract
Based on the anti-inflammatory and antihypertensive properties of garlic, the current study was designed to evaluate the garlic powder effects on blood pressure and high-sensitivity C-reactive protein (hs-CRP) among Nonalcoholic Fatty Liver Disease patients (NAFLD). This randomized, double-blind, placebo-controlled trial study was conducted on 110 patients with NAFLD. The patients were randomly divided into 2 groups, receiving two tablets of either 400 mg garlic or placebo daily for 15 weeks. At baseline and the end of the study, blood pressure and hs-CRP were determined. Of 110 patients enrolled in the trial, 98 subjects were included in the final analysis. After the intervention, systolic blood pressures (SBP) (mean: -7.89; 95%CI:‒11.39 to -4.39 mm Hg), diastolic blood pressure (DBP) (mean: -5.38; 95%CI: -7.77 to -3 mm Hg), and Mean Arterial Pressure (MAP) (mean: -6:95%CI: -8.4 to -3.6 mm Hg) decreased significantly in the garlic group as compared to the placebo group. Also, the percentage of reduced hs-CRP was significantly higher in the intervention group compared with the control group (mean: -16.1; 95%CI: -32.7 to -0.53; p = .035). Moreover, a positive correlation was observed between the percentage change in hs-CRP and percentage changes in SBP (r = 0.221; p = .029), DBP (r = 0.166; p = .012), and MAP (r = 0.210; p = .038). Garlic supplementation can be a safe and potentially adjunct treatment to reduce blood pressure and the risk of cardiovascular disorders in patients with NAFLD.

Abstract
BACKGROUND AND AIM High plasma cholesterol levels, mainly low-density lipoprotein-cholesterol (LDL) is a widely recognized major risk factor for coronary heart disease (CHD). According to epidemiologic studies' findings, people from the Mediterranean countries have lower CHD rates than other countries; in these countries the usual diet is high in olive oil. The present study compares the effects of a cholesterol-enriched diet with or without adding olive oil on serum lipoproteins, lipid peroxidation, and atherosclerosis development. METHODS Twenty Dutch male rabbits were categorized into four groups (one group as control, and others as experimental). They received one of control (CON), olive oil-rich (OIL), cholesterol-rich (CHOL), and cholesterol + olive oil (COIL) diet for 12 weeks. Fasting blood samples from the heart were collected at the beginning and the end of the experimental period. RESULTS Means of serum lipids were not significantly different at the beginning of the experimental period. After the intervention, significant differences were shown in total cholesterol (TC) (CON: 27.75 ± 4.83, OIL: 19.75 ± 2.62, CHOL: 1757.20 ± 149.62, COIL: 2906.40 ± 421.01; P < 0.001), high-density lipoprotein-cholesterol (HDL-C) (CON: 16 ± 1.47, OIL: 10.25 ± 1.70, CHOL: 22.2 ± 3.83, COIL: 28.60 ± 6.27; P = 0.04), triglyceride (CON: 65 ± 12.21, OIL: 71.75 ± 6.23, CHOL: 244.2 ± 44.45, COIL: 775.6 ± 105.07; P < 0.001), and MDA between groups (CON: 0.57 ± 0.10, OIL: 0.63 ± 0.15, CHOL: 5.62 ± 0.18, COIL: 2.06 ± 0.64; P < 0.001). The comparison of CHOL and the COIL groups showed a higher mean of malondialdehyde (MDA) in group CHOL (4.47 ± 0.28 vs 1.1 ± 0.6; P < 0.001). Aortic lesion was not observed in CON and OIL groups. Aortic lesion degree was significantly lower in the COIL group compared to the CHOL (2.4 ± 0.6 vs 3.66 ± 0.33; P = 0.02). CONCLUSIONS These findings showed the preventive effect of olive oil on atherosclerosis development. However, it is independent of the plasma lipoprotein effect, and olive oil probably acts on arteries directly.

Abstract
AIM Rheumatoid arthritis (RA), is a prevalent immune-inflammatory disease, which is associated with disabling pain. Oxidative stress might play a role in RA pathogenesis and outcomes. According to the antioxidant properties of garlic, the current study was performed to evaluate the garlic supplement effects on some serum levels of oxidative stress biomarkers, and quality of life in patients with rheumatoid arthritis. METHODS Seventy women with RA participated in this randomized, double-blind, placebo-controlled, parallel-design trial. The patients were randomly divided into two groups, receiving two tablets of either 500 mg garlic or placebo daily for 8 weeks. Serum levels of total antioxidant capacity (TAC) and malondialdehyde (MDA) and quality of life were determined at baseline and end of week 8. A health assessment questionnaire (HAQ) was used to evaluate the quality of life related to health. RESULTS Of 70 patients enrolled in the trial, 62 subjects were included in the final analysis. At the end of the study, there was a significant increase in serum levels of TAC in the garlic group as compared with the placebo group (26.58 ± 77.30 nmol of Trolox equivalent/ml vs 16.11 ± 0.92 nmol of Trolox equivalent/mL; P = .026). In addition, MDA levels were significantly decreased in the intervention group compared with the control group (-0.82 ± 1.99 nmol/mL vs 0.36 ± 2.57 nmol/mL; P = .032). Pain after activity and HAQ scores decreased in the garlic group compared with the placebo (-11.96 ± 13.43 mm vs -0.06 ± 13.41 mm; P < .001, 0.17 ± 20 vs 0.05 ± 0.15; P < .001, respectively). CONCLUSIONS The findings suggest that garlic supplementation for 8 weeks resulted in significant improvements in oxidative stress, HAQ in women with RA.

Abstract
Based on the antiinflammatory properties of garlic, current study was conducted to evaluate the garlic supplement effects on serum levels of some inflammatory biomarkers, clinical symptoms, and fatigue in women with active rheumatoid arthritis. In this randomized, double-blind, placebo-controlled trial study, 70 women with RA were randomly divided into two groups: The intervention group was supplemented with 1,000 mg of garlic, and the control group received placebo for 8 weeks. At baseline and at the end of the study, clinical symptoms, fatigue, serum level of C-reactive protein (CRP), tumor necrosis factor-a (TNF-a), and erythrocyte sedimentation rate (ESR) were determined. After intervention, serum levels of CRP (p = .018) and TNF-a (p < .001) decreased significantly in the garlic group as compared with the placebo group. Also, pain intensity, tender joint count, disease activity score (DAS-28), and fatigue were significantly decreased in the intervention group compared with the control group (p < .001; for all). Swollen joint count was significantly decreased in the garlic group (p < .001), but not in the placebo group (p = .123). No significant changes were observed for ESR. Garlic supplementation by improving inflammatory mediators and clinical symptoms can be considered as a potential adjunct treatment in patients with RA. However, further studies with larger duration are needed.

Abstract
Background: Parkinson's disease (PD) as one of the most common neurodegenerative disorders may be affected by healthy dietary pattern. The aim of this study was to investigate the effects of the Mediterranean Diet (MeD) on serum Total Antioxidant Capacity (TAC) and disease severity in PD patients.Materials & Methods: In this single-center randomized clinical trial, patients with idiopathic PD (n = 80) were selected randomly allocated to either MeD or control group (Iranian traditional diet); an individualized dietary plan based on the MeD was designed. Serum TAC and the motor & non-motor disease aspects using the Unified Parkinson's Disease Rating Scale (UPDRS) were evaluated in two groups. Statistical Analysis of data was performed using SPSS 24.Results: 70 PD patients with a mean age of 58.96 ± 8.7 and UDPRS of 41.66 ± 20.19 were analyzed in this study. MeD significantly increased serum TAC (P < 0.001). UPDRS score was also lowered in MeD group (P < 0.05).Conclusions: Mediterranean diet seems to have some benefits in PD. as well, TAC levels can also be affected by MeD. Anyway, further studies are needed to confirm the mentioned outcomes.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20141108019853N4.

Abstract
OBJECTIVES Parkinson's disease (PD) is the second most common neurodegenerative disorder. It is proposed that adherence to the Mediterranean diet might have a beneficial effect on the prevention and treatment of PD and its complications. Thus, the aim of this study was to investigate the effects of the Mediterranean diet on cognitive function in patients with PD. DESIGN The study was a single-center, randomized clinical trial. Eighty patients with idiopathic PD were randomly allocated to the Mediterranean diet (n = 40) or control (n = 40) group. Patients in the intervention group received an individualized dietary plan based on Mediterranean diet for 10 weeks. The Persian version of Montreal Cognitive Assessment (MoCA) test was used to assess the cognitive function at baseline and the end of the study. RESULTS Thirty-five PD patients with a mean age of 59.3 ± 8.3 and 35 patients with a mean age of 58.6 ± 9.3 finished the study in intervention and control groups, respectively. After the intervention, the mean score of the dimensions of executive function, language, attention, concentration, and active memory and the total score of cognitive assessment significantly increased in the intervention compared with the control group (p < 0.05, for all). Nevertheless, the mean of the other scores including spatial-visual ability, memory learning task, and navigation versus time and place did not significantly change in both intervention and control groups. CONCLUSIONS The findings of this study showed that adherence to the Mediterranean diet remarkably increased the dimensions of executive function, language, attention, concentration, and active memory and finally the total score of cognitive assessment in PD patients.

Abstract
Aim: Coronary artery disease (CAD) is a major cause of mortality worldwide. Many studies suggest that dietary antioxidant can offer significant protection against stroke, heart failure, and coronary heart disease. However, there is no study that assessed the association between dietary TAC and severity of stenosis in patients with CVD. The aim of this study was to investigate the association of dietary TAC and severity of stenosis in patients with coronary artery disease. Methods: Dietary and medical History of 160 patients with CAD were assessed. The extent of Stenosis was determined using the Gensini score. Dietary history was investigated by food frequency questionnaire (FFQ), and Dietary TAC was calculated by multiplying the average frequency of intake of each food by oxygen radical absorbance capacity (ORAC) content. Results: Across the Gensini score quartiles the dietary TAC, dietary hydrophilic TAC, dietary lipophilic TAC, and dietary phenolic TAC values were significantly increased in the highest quartile compared with the lowest quartile (dietary TAC (mmolTE/100 g):17.5 ± 1.82 vs. 11.2 ± 1.90; dietary hydrophilic TAC (mmolTE/100 g): 16.56 ± 1.29 vs. 10.74 ± 1.81; dietary lipophilic TAC (mmolTE/100 g): 0.55 ± 0.12 vs. 0.23 ± 0.09; dietary phenolic TAC (mmolTE/100 g):1.84 ± 0.31 vs. 0.98 ± 0.21; (P < 0.001 for all)). However, a non-significant association between the plasma TAC and Gensini quartiles was observed (P = 0.789). Multivariate regression analysis showed that dietary TAC (Beta = -0.53; P < 0.001) was statistically significant independent predictors that associated with the Gensini score values. Conclusions: There was a significant association between dietary TAC and severity of stenosis in patients with coronary artery disease.

Abstract
BACKGROUND AND AIMS Emerging evidence suggests that garlic (Allium sativum L.) and its bioactive components can mitigate hepatic steatosis by the modulation of hepatic lipid metabolism. We aimed to assess the efficacy of the garlic administration on hepatic steatosis in patients with NAFLD. PATIENTS AND METHODS This clinical trial was conducted on adult patients with ultrasound-diagnosed NAFLD. Eligible participants were randomly assigned, with the use of the stratified blocked procedure, to receive 800 mg garlic or placebo for 15 weeks. The primary outcome was the improvement in the hepatic steatosis diagnosed by ultrasound technique after 15 weeks of intervention. RESULTS A total of 110 patients underwent randomization, and 98 patients completed the trial. Twenty-four (51.1%) patients in the garlic group achieved improvement in the hepatic steatosis compared to eight (15.7%) patients in the placebo group with the relative risk of 5.6 (95% CI: 2.17 to 14.5; P=0.001), which remained significant after adjusting for baseline value of hepatic steatosis. There were significant reductions in weight and serum ALT, AST, FBS, Hb A1C, total cholesterol, LDL-cholesterol, and TG concentration with the garlic intake compared to placebo (P<0.05). The results were also significant after adjusting for weight change, energy intake, and physical activity. No serious adverse effects were observed with the garlic intake. CONCLUSION The intake of garlic powder was accompanied by a significant improvement in the hepatic steatosis and comorbidity related to this condition among subjects with NAFLD.

Abstract
BACKGROUND Dietary habit can play a key role in the prevention and treatment of fatty liver disease (NAFLD). Although many studies have investigated the effect of Mediterranean diet on NAFLD, findings are inconsistent and there is no systematic review on this topic. Therefore, the aim of this systematic review is to summarize the effect of Mediterranean diet on serum metabolic indices and anthropometric measures among NAFLD patients. METHODS We searched titles, abstracts, and keywords of articles indexed in Science Direct, MEDLINE, and Google Scholar databases up to October 2018 to identify eligible RCT studies. Randomized clinical trials assessing the effects of MD on NAFLD were included. RESULTS The present study included 10 randomized controlled trials, which involved a total of 856 adults with NAFLD. According to the result, MD may improve anthropometric measures, lipid profile, glycemic indices, liver enzyme, and NAFLD severity indices among patients with NAFLD. CONCLUSION We found that MD could alleviate NAFLD severity parameters but differences between studies should be taken into account. Finally, in order to draw a firm link between MD and NAFLD, more clinical trials with adequate sample size and better methodology should be done.

Abstract
Purpose
Dietary fiber and energy intakes seem to be related to disability and anthropometric indices in multiple sclerosis (MS), a chronic inflammatory disorder of the central nervous system. So, this study was designed to investigate the association between dietary fiber and energy intakes with systemic inflammation, disease severity and anthropometric measurements in MS subjects.
Design/methodology/approach
Four subtypes of 261 MS volunteers were recruited (female = 210, male = 51; mean age 38.9 ± 8.3). A 168-item food frequency questionnaire and nutritionist IV software were used to estimate the amounts of dietary, insoluble, soluble, crude fiber and energy intakes. Serum hs-CRP, extended disability status scale (EDSS), height, weight and Deurenberg equation were also used to evaluate systemic inflammation, disease severity, body mass index (BMI) and percentage body fat, respectively.
Findings
Mean differences among the three hs-CRP and EDSS subgroups for dietary fibers and energy intake were significant (p < 0.001). Dietary fiber intake (M = 19.9 ± 4.3 g/day) was a good predictor for EDSS (B = −0.196, p = 0.012), and insoluble fiber intake was introduced as the best predictor of hs-CRP (B = −3.293, p < 0.001). Energy intake predicted both BMI (B = 0.007, p < 0.001) and percentage body fat (B = 0.015, p < 0.001).
Originality/value
Hypocaloric and high prebiotic fiber diet may suppress systemic inflammation and thereby modulate disease severity, as well as control anthropometric indices.

Abstract
BACKGROUND Obese adolescents are at higher risk of development of cardiovascular risk factors and obesity in later life. Dietary intake of antioxidants, particularly curcumin, as an active ingredient of turmeric extract, may have noticeable effects on obesity and its important complications such as cardiovascular risk factors. Therefore, the aim of this study was to assess the effects of curcumin supplementation on cardiovascular risk factors among overweight and obese female adolescents. DESIGN AND SETTING Randomized placebo-controlled clinical trial; Pediatric Cardiovascular Research Center, Isfahan, Iran. METHODS 60 adolescent girls (aged 13-18 years) were randomly assigned to receive either placebo or intervention. The adolescents were asked to consume one 500 mg tablet per day, containing either standardized 95% turmeric extract or placebo, and to undergo a weight maintenance or a mild weight loss diet for 10 weeks. Anthropometric and biochemical indices were assessed at the baseline and the end of the intervention. RESULTS Curcumin supplementation had beneficial effects on body mass index (P = 0.019), waist circumference (P = 0.008), hip circumference (P = 0.030), high-density lipoprotein levels (P = 0.042) and triglyceride/high-density lipoprotein ratio (P = 0.021). However, in univariate analysis of covariance, no significant differences were found between the intervention and placebo groups after 10 weeks of supplementation (P > 0.05). CONCLUSIONS Prescription of curcumin supplementation along with use of a slight weight loss diet might have beneficial effects on some cardiovascular risk factors among overweight and obese female adolescents. Larger clinical trials with higher curcumin doses and longer duration are needed to confirm the results from the current study. CLINICAL TRIAL REGISTRATION IRCT20171107037302N1.

Abstract
INTRODUCTION It is well known that there is a strong linkage between obesity, systemic low-grade inflammation, and oxidative stress in the pediatric population. Possible strategies that might control obesity and its relevant problems in this crucial group are of utmost importance. Therefore, the aim of this study was to evaluate the effects of curcumin supplements on inflammation, oxidative stress, and chemerin levels in adolescent girls. METHODS Totally, 60 overweight and obese adolescent girls were randomly assigned to either placebo or intervention group in a randomized placebo-controlled parallel trial design. Adolescents consumed one 500-mg curcumin or placebo per day along with a slight weight loss diet for 10 weeks. High-sensitive C-reactive protein (hs-CRP), interleukin 6 (IL-6), total antioxidant capacity (TAC), malondialdehyde (MDA), chemerin levels, and anthropometric measurements were assessed at the beginning and end of the trial. RESULTS Curcumin supplementation had a significant effect on IL-6 levels and oxidative stress markers including TAC and MDA in crude model. After controlling the effects of confounders, curcumin supplementation had a substantial effect on inflammation (hs-CRP and IL-6) and oxidative stress (TAC) marker of adolescents. DISCUSSION Ten weeks of curcumin supplementation had beneficial effects on inflammation and oxidative stress markers among postpubescent overweight and obese girl adolescents.

Abstract
Background: Vitamin D plays an important role in nervous health and depression. Vitamin D deficiency and anxiety affect diabetic status. The purpose of this study was to determine the effect of vitamin D supplementation on anxiety, depression, and inflammation in diabetic women with anxiety. Methods: In this randomized controlled trial, totally 51 women with type 2 diabetes (T2DM) and vitamin D deficiency were randomly allocated to receive one oral pearl of 50,000 IU vitamin D3 (26 women) or a placebo (25 women) fortnightly for 16 weeks. Anthropometric indices, sun exposure, dietary intake, depression, anxiety, and stress scores and biochemical biomarkers including high sensitivity C-reactive protein (hs-CRP) and interleukin-10 (IL-10) were measured at the baseline and after 16-week supplementation. Results: Mean ± SD age of participant was 47.43 ± 9.57 years old. Baseline values were not different between the groups. Anxiety score changes were significantly lower in vitamin D group than the controls (P = 0.001). Within group comparison indicated that depression in supplement group with lower vitamin D levels was significantly reduced. Serum hs-CRP reduced (P = 0.01), while IL-10 concentrations increased (P = 0.04) in the intervention group. Conclusions: Vitamin D supplementation can improve mood status and anti-inflammatory biomarkers in female diabetics with anxiety and vitamin D deficiency.

Abstract
PurposeMetabolic syndrome (MetS) is a complex disorder that exacerbates the risk of cardiovascular disease and diabetes mellitus; some studies have indicated the beneficial effects of green tea on human health. The purpose of this study is to investigate the effects of green tea consumption on the MetS indicators in women.Design/methodology/approachA randomized clinical trial was carried out on 70 eligible women with confirmed diagnosis of MetS who visited Shabani Diabetes Clinic (Isfahan, Iran). Participants were randomly divided into two groups. Participants in the Green Tea Group were asked to consume three 200 cc of green tea in the morning, at noon and at night for eight weeks, while people in the control group were asked to take identical amount of lukewarm water at the same schedule. Anthropometric indicators, blood pressure, blood sugar, lipid profile, diet and physical activity were assessed at the beginning and the end of the study.FindingsAn independentt-test showed that weight (p =0.001), body mass index (p =0.001), waist circumference (p< 0.001) and waist–hip ratio (p =0.02), systolic blood pressure (p =0.04), fasting blood glucose (p =0.01) and low density lipoprotein (p =0.03) changed significantly more in the Green Tea Group than in the control group; but no such inter-group difference was observed in diastolic blood pressure, triglyceride, total cholesterol and high density lipoprotein (HDL) values (p> 0.05).Originality/valueRegular consumption of green tea for eight weeks significantly improved anthropometric indices, blood pressure, blood sugar and lipid profile in women with MetS. Therefore, this beverage can serve as part of an effective dietary strategy to control MetS.

Abstract
Maternal nutritional status during pregnancy will affect the outcomes for the mother and the newborn. Maternal diet was assessed in 150 pregnant women during the first trimester of pregnancy by a 168-item food frequency questionnaire. Dietary patterns were explored by Factor analysis, and association of patterns with maternal and neonatal outcomes such as gestational diabetes mellitus (GDM), anemia and anthropometric indices were determined by analysis of variance and linear regression analysis. Three major dietary patterns were identified: 1) High Carbohydrate-Lower Fat (mean age, 27.67 ± 6.1; n = 34), 2) High Carbohydrate-Higher Fat (27.70 ± 4.1; n = 55), and 3) High Fiber (29.27 ± 5.8; n = 61). A significant difference was observed between maternal dietary patterns (p < 0.01) for GDM, while it was not significant for anemia. Also, the number of preterm and low birth weight (LBM) infants as well as mean weight, height and head circumference of the infants did not differ significantly between patterns, but there was a significant difference between the maternal dietary patterns about the number of macrosomic babies, which was higher in the second (n = 9) and third (n = 9) dietary patterns (p < 0.01). After adjusting for mothers' age, disease history, disease status, and energy intake, High Carbohydrate-Lower Fat dietary pattern was more associated with GDM than crude model (p = 0.01 vs. p = 0.02). The present study indicated a significant relationship between maternal dietary patterns before pregnancy and GDM and fetal macrosomia.

Abstract
Background: Correct health behaviors such as dietary habits before pregnancy ensure desired pregnancy outcomes. The aim of this study was to determine the relationship between psychosocial factors and dietary habits using social cognitive theory (SCT) in women undergoing preconception care (PCC). Materials and Methods: This cross-sectional study was conducted among 120 women from October to December 2015 in health centres in Isfahan, Iran. Using a researcher-made questionnaire, the researcher conducted stratified random sampling and convenience sampling for selecting health centres and participants, respectively. For data analysis, the researcher applied the Pearson, Spearman's, and linear regression test in SPSS software. Results: The results showed that perceived support from healthcare personnel and outcome expectations are not associated with any of the components of dietary habits. Access to healthy food was inversely correlated with incorrect dietary habits (β = −0.19, p = 0.039) and had a direct correlation with daily consumption of fruits (β = 0.27, p = 0.006). Perceived support from the spouse had a direct correlation with desired dietary habits (β = 0.27, p = 0.006). Self-efficacy was inversely correlated with incorrect dietary habits (β = −0.22, p = 0.011) and had a direct relationship with desired dietary habits (β = 0.25, p = 0.004). Conclusions: To improve the nutritional status of women prior to pregnancy, interventions must be focused on increasing women's access to healthy food and their self-efficacy in maintaining a healthy diet.

Abstract
Background Nutrition during pregnancy is undoubtedly one of the most important factors affecting maternal health. In this regard, considering the cognitive-behavioral factors associated with feeding, behaviors will play an important role in the effectiveness of interventions. Therefore, this study aimed to investigate the correlation between food habits and structures of social cognitive theory in pregnant women. Materials and Methods In this cross-sectional study, 192 pregnant women were randomly selected. Data were collected using a questionnaire based on the social cognitive theory structures and food habits questionnaire in the questioning manner and was also analyzed using Pearson correlation and multiple linear regression with the software Statistical Package for the Social Sciences, version 19. Results There was a significant correlation between nutritional behavior with self-regulation (p = 0.001), self-efficacy (p = 0.001), outcome expectations (p = 0.001), social support (p = 0.002), and access (p = 0.001). A significant correlation was observed between lack of consumption of unnecessary and unhelpful food with self-regulation (p = 0.02). In the multivariable regression analysis, only self-regulation revealed significant and direct contribution in relation to nutritional behavior (p < 0.001). Conclusions Results of this study showed that self-regulation is one of the important factors associated with feeding behavior in pregnant women so that it is suggested to be considered in nutritional interventions in order to improve nutritional behavior.

Abstract
Gestational diabetes mellitus (GDM) is an impaired fasting glucose condition during pregnancy. Adiponectin is a polypeptide hormone that is extensively released by adipocytes which regulates energy homeostasis and carbohydrate and lipid metabolism. In addition, adiponectin has antidiabetic and anti-inflammatory properties. The aim of our research was to study about the relationship of adiponectin levels to GDM and glucose intolerance. We selected 25 GDM women and 35 healthy pregnant subjects (18–46 years) who were screened between 24 and 28 weeks of gestation based on the result of oral glucose tolerance test (OGTT). We designed a case-control study and measured the concentrations of serum adiponectin and compared the concentrations between the groups. Serum adiponectin concentration was measured using enzyme-linked immunosorbent assay (ELISA). Sociodemographic data were collected by personal interview. Serum adiponectin concentrations were significantly lower in the subjects with GDM (5.10 ± 2.15 ng/mL vs. 7.86 ± 3.52 ng/mL, p = 0.001) than in healthy pregnant subjects. The mean concentration of fasting blood glucose was considerably lower in control subjects (86.9 ± 9.0 mg/dL vs. 175.9 ± 20.1 mg/dL, p < 0.001) in comparison to GDM subjects. Our findings showed that serum concentrations of adiponectin were significantly lower in gestational diabetic women and this may help to predict the risk of GDM.

Abstract
Background Regarding to the complications of malnutrition in dialysis patients, using an easy and reliable method for evaluating of malnutrition is important in patients with the end-stage renal disease. Based on the effect of inflammatory factors in malnutrition, A new scale has been designed which is called malnutrition-inflammatory scale (MIS). We designed current study to assess the severity of malnutrition in peritoneal dialysis patients in Isfahan via MIS. Materials and Methods In this cross-sectional MIS was used for evaluation of malnutrition. MIS includes 10 components: dry weight changes, dietary intake, functional capacity, comorbidity, muscle wasting and loss of subcutaneous fat as well as body mass index (BMI), serum albumin level and total iron binding capacity (TIBC). Each component has four levels of severity from 0 (normal) to 3 (severely abnormal). All analyses were performed using Statistical Package for Social Sciences version 20 (SPSS 20) and P < 0.05 were considered statistically significant. Results Results showed no significant difference in MIS between male and female participants. Mean of minimum inhibitory concentration in this study was calculated about 4.1 (MIS <9) which means no or mild malnutrition. Significant correlation between MIS and weight (P < 0.001), BMI (P < 0.001), TIBC (P < 0.001), triglyseride (P = 0.04) and arm circumference (P < 0.001) was seen. Conclusion We suggest That MIS is being used as a valuable tool for prevention of fatal outcomes in chronic dialysis patients.

Abstract
Gestational diabetes mellitus (GDM) is described as glucose intolerance diagnosed during pregnancy. Increased oxidative stress has implicated in diabetic problems. The aim of the current study was to compare antioxidant capacity and antioxidant nutrient intake between women with GDM (n = 40) and healthy pregnant women (n = 40). Demographic and obstetrics data were completed using interview technique and dietary intakes by using a semi-quantitative food frequency questionnaire (FFQ) with 168 items. The total antioxidant capacity (TAC) of serum was assessed by double-antibody sandwich enzyme-linked immune-sorbent assay (ELISA) method. Multivariate logistic regression was performed to compare independent variables and other potential risk factors between 2 groups. The results showed that TAC concentration of serum in women with GDM was significantly lower than in healthy pregnant women (2.3 ± 0.7 vs. 3.7 ± 0.1 µmol/L, p < 0.001). Intakes of vitamin E (11.8 + 3.1 vs. 16.2 + 3.1 mg, p < 0.001), selenium (81 ± 26 vs. 95 ± 36 µg, p < 0.05) and zinc (7.4 ± 1.9 vs. 9.1 ± 1.7 mg, p < 0.001) were significantly lower in women with GDM as compared to healthy pregnant women. In contrast, the groups showed no significant difference in vitamin C, β-carotene, selenium, fruit, and vegetable intake. Our findings showed that antioxidant capacity is lower in women with GDM, possibly related to lower intakes of vitamin E and zinc.

Abstract
Preeclampsia (PE) is one of the major disorders in pregnancy leading to many adverse maternal outcomes. Although the etiology of PE is not fully understood, resent studies suggest that an imbalance between free radicals production and the antioxidant defense system might have key role. Our aim of the current study was to evaluate the association between dietary total antioxidant capacity (TAC), serum TAC and risk of PE in women with preeclampsia and normal pregnancy. This case-control study conducted on 55 women with preeclampsia and 93 with normal pregnancy. Dietary intakes were obtained by a semi-quantitative food frequency questionnaire (FFQ) with 168 itmes. Dietary TAC was assessed according to United States Department of Agriculture (USDA) Database for oxygen radical absorbance capacity (ORAC), Release 2. Serum TAC was measured by a double-antibody sandwich enzyme-linked immunesorbent assay (ELISA). After adjusting for energy, pre-pregnant body mass index (BMI) and history of PE, no relationship was found between intake of hydrophilic-ORAC (H-ORAC), lipophilic-ORAC (L-ORAC), total phenolics (TP), total-ORAC (T-ORAC), and PE risk. However, serum TAC had a significant positive relationship with the risk of PE after adjusting for energy (odds ratio [OR], 0.07; 95% confidence interval [CI], 0.16-0.35), BMI and history of PE (OR, 0.04; 95% CI, 0.01-0.32). Findings of this study indicate that serum TAC is positively associated with the risk of PE but no association was found between intake of antioxidant indices and PE risk.

Abstract
Background: Health evaluation is carried out using various anthropometric methods including waist–hip ratio (WHR) index. This method is applied for estimating body fat distribution. This study was aimed to investigate the socioeconomic and reproductive determinants of WHR index in menopausal women. Materials and Methods: For this cross-sectional study, samples were 278 menopausal women in Isfahan, Iran, who were selected by stratified sampling and invited to ten health centers. The data collection tools were a questionnaire and the standard meter tape. Data were analyzed using descriptive and inferential statistical tests. Results: The mean of WHR index was X̄ = 0.9 ± 7.54. There was a significantly statistical relation between age, job, educational status, number of pregnancies and deliveries, age of the first delivery, and WHR index. Conclusion: Based on the results, body fat distribution of menopausal women is of android (central) type. It is suggested that measuring WHR index should be done in menopausal women and also during the postpartum period in specific intervals. Furthermore, women should be familiarized with related factors to this index, and it is recommended to avoid pregnancy and delivery at early ages and repeated pregnancies.

Abstract
BACKGROUND Since preterm premature rupture of membranes (PPROM) is one of the most important complications of pregnancy and its relationship with nutrition status have not been surveyed comprehensively, we decided to study the relationship of maternal received nutrients (36 macro- and micro-nutrients) in three trimesters and PPROM which could be considered as a unique study. MATERIALS AND METHODS In this prospective cohort study, data was collected by filling a questionnaire through interviews with 620 pregnant women who had no parameters to affect pregnancy outcome. 48-hr dietary recalls were completed for eligible women at 11th-15th, 26th, 34th-37th weeks of gestation. Physical activity was also assessed using a standard questionnaire. Also pregnant mother's reproductive and demographic characteristic and supplementation are considered. RESULTS The mean value of received saturated fatty acids, polyunsaturated fatty acids and energy, in the first trimester (P < 0.001, P = 0.007, and P < 0.001 respectively), the mean values of calcium, sodium intake in the second trimester (P = 0.045, P = 0.006, and P = 0.004 respectively), Vitamins C, A (mg), β-carotene, cartenoids intake in the second trimester (P = 0.03, P = 0.001, P = 0.007, and P = 0.01 respectively), and higher Vitamin C intake during the first trimester (P = 0.02) was significantly greater among subjects with PPROM compared to the others. CONCLUSIONS The mean value of mentioned received nutrients in subjects who experienced PPROM later in pregnancy was higher than the others, which is independent of demographic and reproductive characteristic, estimated physical activity, and supplementation. Therefore, these findings could be considered in the nutritional programming for pregnant women to manage the risk of PPROM.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. Smoking is the number one cause of COPD; however, genetic, environmental and dietary factors contribute to the etiology of this disease. In this study, we assessed the association between three diet quality indices -the Healthy Eating Index-2005 (HEI-2005), the Healthy Eating Index-2010 (HEI-2010), and Mediterranean Diet Score (MED)- and the severity of disease in COPD patients. METHODS This cross-sectional study was performed at Rasul-e-Akram Hospital in Tehran on 121 COPD patients with the mean age of (SD) of 66.1(10.9) years. A pulmonary specialist diagnosed all participants based on a spirometry test. They were categorized into four groups (1, 2, 3, 4 stages of disease). Three diet quality indices, spirometry test and determination of disease severity were performed for all the participants. ANCOVA and Kruskal-Wallis test were used to assess the relationship between dietary quality indices and severity of the disease. The relationship between HEI-2010, HEI-2005, MED score, their components and lung function was assessed using a multiple linear regression analysis. All analyses were done using SPSS 18. RESULTS Reduction of the Healthy Eating Index-2010 and MED score were observed along with the increase in disease severity, but they were not significant. The relationship between the three diet quality indices and lung function showed a significant association between MED score and Forced expiratory volume in one second (FEV1), The Forced Vital Capacity (FVC) (β=2.9, 95% CI (1.1, 4.8), p=0.002), (β=2.8, 95% CI (0.9, 4.8), p=0.007), respectively. CONCLUSION Mediterranean dietary pattern and obtaining a better score on HEI-2010 diet were associated with a better lung function test.

Abstract
Background: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease that is becoming a public health problem in recent decades. Obesity and overweight play a key role in NAFLD pathogenesis. Thus, weight loss (especially body fat mass) is one component of therapeutic strategies in NAFLD. Results from experimental studies have shown that garlic (Allium sativum L.) can reduce body weight and body fat mass. However, the effect of garlic on body fat mass and weight in the human population, which is addressed in this study, is still obscure. Materials and Methods: In this clinical trial, 110 subjects with NAFLD were randomly assigned to the intervention or the control group. The intervention group received two garlic tablets (containing 400 mg of garlic powder) daily while the control group received placebo tablets. Dietary intake and physical activity of participants were obtained by a validated questionnaire. Body composition was measured by bioelectrical impedance analysis. Data were analyzed using SPSS software version 16. Results: In the intervention group, significant reductions were observed in body weight and body fat mass (P < 0.05). We also observed a significant reduction in body weight in the control group, but there were no significant changes in total body water and lean body mass in both groups (P > 0.05). In the intervention group, the percentage change in body weight was significantly greater than the control group (−2.6 vs. −0.7, P = 0.02). No serious side effects associated with the intervention were reported. Conclusion: Our trial suggests that garlic supplemfrom experimental studies have shown thatentation can reduce body weight and fat mass among subjects with NAFLD.

Abstract
Background: Preeclampsia (PE) is the most common cause of maternal death in the world. Some studies showed that inadequate intake of foods rich in antioxidant leads to increase oxidative stress and adverting obstetrical outcomes. The aim of the present study was to investigate the relationship between antioxidant status and dietary nutrient intake in pregnant women with PE. Materials and Methods: This cross-sectional study was conducted among 55 pregnant women with PE admitted in the Obstetrics and Gynecology department of Shahid Beheshti Hospital in Isfahan, Iran. The subjects were interviewed about demographic data and dietary intakes by using a 168-items semi-quantitative food frequency questionnaire (FFQ). The total antioxidant capacity (TAC) of this serum was measured by using a double-antibody sandwich enzyme-linked immune-sorbent assay (ELISA). Nonparametric correlation statistics were used to meet assumptions of normality and equal variances. Results: Total antioxidant status was significantly higher in comparison with healthy pregnant women (which measured as pilot). Intake of vitamin E was below the dietary reference intakes, and was positively associated with serum TAC (r = 0.367, P = 0.003), but this correlation was significantly negative about dietary selenium. There wasn’t any significant correlation between intake of vitamin C, β-carotene, riboflavin, copper and serum TAC. Conclusion: Our findings showed that intake of vitamin E was positively associated with serum TAC. Little support was found on a relationship between dietary intakes of other micronutrients and serum TAC. Further research is required to explore the relationships between maternal nutrient intake and antioxidant status in women with PE.

Abstract
BACKGROUND Lifestyle factors such as weight, salt intake, and physical activity have shown to be important in treating hypertension. The object of this study was to describe feasibility and to assess the effectiveness of a multicomponent lifestyle intervention on high blood pressure (BP) of Iranian women. MATERIALS AND METHODS This randomized controlled trial was conducted in four health centers by recruiting 161 women aged 35-65 years with high BP and randomizing them to a 4-week lifestyle modification (n = 80) or control group (n = 81). BP level and other health behavioral factors were assessed before and after the 4-week intervention and also after 6 months. RESULTS The mean systolic BP changed from 158.8 (±8.1) mmHg to 153.2 (±6.4) mmHg during 4-week and to 145.5 (±4.6)) mmHg after 6 months in the intervention group (P < 0.001). There was a significant difference between two groups of study after 4-week mean = 5.6 (confidence interval [CI] = 5.1-6.6) and 6 months follow mean (CI = 12.3-14.6).(P < 0.001) A significant correlation was detected between systolic BP (SBP) and diastolic BP (DBP) with weight, body mass index, waist circumference, salt intake, and physical activity level (P < 0.001). Stepwise regression analyses indicated that the weight, dietary salt intake, and physical activity level were significant predictors of SBP and DBP. CONCLUSION The results of this study suggest that lifestyle modification program is associated with improvements in BP level in Iranian women.

Abstract
BACKGROUND Dietary intervention for improving serum lipids emphasizes on dietary fiber, plant protein, and flavonoids. This study was performed to examine whether regular legume consumption could alter serum lipids level and prevalence of dyslipidemia. MATERIALS AND METHODS This cross-sectional study was performed among 9660 randomly selected Iranian adults in 3 districts in the central part of Iran, using data collected in the Isfahan Healthy Heart Program in 2007. Dietary behavior including frequency of legume consumption was assessed by 48-item food frequency questionnaire. Fasting serum lipids were measured by standard enzymatic methods. We applied analysis covariance test to compare adjusted mean of serum lipids across legume consumption quartile and logistic regression test was used to determine odds ratio 95% confidence interval of dyslipidemia based on legume consumption in unadjusted and 4-adjusted models. RESULTS Adjusted mean triglyceride significantly reduced and high-density lipoprotein cholesterol (HDL-C) enhanced by increasing legume consumption (P = .04). The frequency of legume consumption associated with occurrence of all kinds of dyslipidemia except for hypercholesterolemia, especially for those who had consumed legume more than 1 time per day in adjusted models (hypertriglyceridemia: 0.82 [0.68-0.98]; high low-density lipoprotein [LDL-C]: 0.76 [0.60-0.97], and low HDL-C: 0.81 [0.71-0.92]). CONCLUSION We found an inverse dose-response association between the frequency of legume consumption and the risk of hypertriglyceridemia, high LDL-C, and low HDL-C. Therefore it is suggested that increasing legume intake may be an important part of a dietary approach for primary prevention of cardiovascular disease.

Abstract
BACKGROUND Osteoporosis is a serious public health. Since the majority of bone mass occurs during adolescence, primary prevention is important. Probably mother's participation in health education interventions leads to promote health behaviors in children. AIMS To assess a lifestyle modification intervention focused on mothers and students has an impact on osteoporosis preventive behaviors in adolescent girls. MATERIALS AND METHODS It is a randomized field trial in female high schools. 210 girls aged between 11 and 15 were randomly selected. Students in groups A and C and mothers in group B were selected Through the sampling frame. Our lifestyle modification was based on group based education in the public girls' high schools. Subjects in the intervention groups participated in three educational sessions. Students' osteoporosis preventive behaviors were measured by using a lifestyle questionnaire consisting of items assessing nutrition, physical activity and sun exposure. Repeated measure ANOVA at baseline, 4 week, 2 months and 6 months and were used to analyze the data. RESULTS After 1 month, diet and sun exposure scores increased significantly (P < 0.001) but it was higher in group B compared with group A. (About diet P < 0.001 and sun exposure = 0. 001). After 6 months, diet and sun exposure status in the group A approximately decreased to baseline, while in group B, diet components were significantly different compared to baseline (P < 0.001). There was no change in physical activity. CONCLUSION Osteoporosis prevention intervention of adolescent can be effective when parents or girls participate in training sessions, but education is associated with better outcomes when focused on mothers.

Abstract
Background: Atherosclerosis, with its major manifestation, coronary artery disease (CAD) is a chronic inflammatory disease. Dietary fatty acids intakes favorably effect on inflammatory responses. This study was conducted to examine the association between dietary fatty acid intakes and inflammatory markers, interleukin 6 (IL-6) and high sensitivity C-reactive protein (hs-CRP), in CAD patients among Iranian population. Materials and Methods: This hospital-based, cross-sectional study was conducted in Chamran Heart Hospital, Isfahan, Iran in 2012. Patients aged ≥45 years with first ever symptomatic CAD confirmed by angiography were included. A semi-quantitative food frequency questionnaire (FFQ) was used to assess the usual intakes of dietary fatty acids. Results: The energy-adjusted daily intakes (mean ± SD) of saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), linoleic acid, α-linolenic acid, and eicosapentaenoic acid and docosahexaenoic acid (EPA + DHA) were 27 ± 9, 22 ± 6, 21 ± 5, 0.4 ± 0.32, and 0.85 ± 0.82 g/d; respectively. After adjustment for potential confounders, SFA was directly related to hs-CRP (P = 0.01) and IL-6 (P < 0.001) concentrations. Intakes of EPA + DHA and MUFA, were significantly adversely related to plasma hs-CRP concentration (P = 0.002 and 0.001, respectively) but not IL-6, albeit MUFA was modestly inversely related to IL-6 (P = 0.08). No significant relationships were observed for other fatty acids, α-linolenic acid, and linoleic acid. Conclusions: These findings suggest that saturated fatty acids, EPA + DHA and MUFA were significantly related to plasma inflammatory markers in CAD patients.

Abstract
Background: Poor vitamin D status and low serum insulin-like growth factor-1(IGF-1) are associated with metabolic syndrome (MetS) and its components. But, there is no adequate evidence about this. The aim of this study was to examine relationship of factors with MetS features. Materials and Methods: In this cross-sectional study, 156 women aged 28-76 years with MetS were recruited by consecutive random sampling. Dietary vitamin D, serum 25-hydroxyvitamin D (25(OH) D) and IGF-1 levels and also MetS components were determined. Result: The mean of serum 25(OH) D and IGF-1 concentrations were 20.5 ± 10.8, 194 ± 47 ng/mL, respectively. Overall, near 54.5% and 24% of subjects were vitamin D deficienct and insufficienct respectively. Univariate regression analysis showed that 25(OH) D concentration was negatively correlated with fasting blood sugar (P < 0.001) and no significant relation was observed between vitamin D status and serum IGF-1 with blood pressure and waist circumference. Multivariate regression analysis showed positive relation of 25(OH) D concentration with HDL-cholesterol (P = 0.031) and also dietary vitamin D is positively correlated with triglyceride (P = 0.026). IGF-1 as a predictor was not related to any of the MetS components. Conclusion: Our findings show that vitamin D status was related to FBS, HDL-C and triglyceride concentration; hence, with regard to findings of previous studies it seems that vitamin D is related to components of MetS. However, to determine the role of vitamin D status and IGF-1 in the development MetS and related components, further longitudinal studies and randomized clinical trials should be prescribed.

Abstract
INTRODUCTION Osteoporosis is a multifactorial disease and one of the most important modifiable factors in the development and maintenance of bone mass are nutrition nutritional status and its relationship with Bone Mass Density (BMD) in postmenopausal women admitted in osteodensitometry Center, Isfahan, Iran. MATERIALS AND METHODS Seventy-two postmenopausal osteoporotic women were studied. BMD of the lumbar spine and total hip were measured using dual-energy X-ray absorptiometry. Demographic and dietary intakes were collected by interview and using a validated food frequency questionnaires. T-scores, Pearson correlation and one way analysis of variance tests were conducted to analyze the data. RESULTS Mean of age and duration of menopause was nearly 57.5 ± 7.2 and 10.6 ± 7.1 years, respectively. The mean t-scores for BMD of spine and hip were 0.877 ± 0.179 and 0.997 ± 0.21, respectively. The mean of calcium (Ca), phosphorous (P), fluoride (F), Vitamin D, K and Zn were less than DRI and Na more than it (all P value less than 0.0001). BMD of hip was significantly correlated with dietary Ca, animal protein, Zn (P < 0.05), but BMD of spine did not show any significant correlation with nutrients (P > 0.05). CONCLUSION Most of the postmenopausal osteoporotic women in this study had a considerable deficiency in terms of micronutrients such as Ca, vitamin D and P, which can be deleterious for bone health.

Abstract
BACKGROUND Nutrition in childhood has a significant role in current and adulthood health. Recent studies have shown that the mother's life-style has an important role in the methods used by mother to feed child, child's diet and body mass index (BMI). This study paper aimed to investigate the association between mother's weight efficacy life-style (WEL) with feeding practices and diet in children aged 3-6 years. METHODS In this cross-sectional study, which was carried out in 18 Primary Schools of Rasht (Iran) in 2012, 165 mothers with children aged 3-6 years were participated. Mothers reported their own and their child's demographics. Aspects of mother's WEL and mother's control practices were assessed using WEL questionnaire and Comprehensive Feeding Practices Questionnaire respectively. Height and weight of mothers participated in the study were measured. Child's dietary intake was measured using Food Frequency Questionnaire (FFQ). The role of mother's weight efficacy in predicting child's feeding practices and child's diet was assessed using the linear regression. Statistical significance for all P values was set at 0.003. RESULTS The results were showed that mother's weight efficacy was related to child feeding practices and child's dietary intake. The mothers with similar WEL applied similar methods in child nutrition. Mothers with better weight efficacy used more encourage balance and variety (β = 1.860), environmental control (β = 0.437), child involvement (β = 0.203) and less emotion regulation using foods (β = -0.213) and their children eat fewer snacks (β = -0.318) (PV= 0.003). CONCLUSIONS The result of this study showed that maternal life-style was associated with feeding practices and child's intake. There was no significant relation between the maternal self-efficacy and child BMI.

Abstract
BACKGROUND Designing an intervention based on healthcare settings resources and patient acceptability is potentially important in the prevention of high blood pressure(BP) and other risk factors of cardiovascular disease. To explain a multicenter randomized controlled trial that is designed to examine the effects of the multicomponent lifestyle modification program on BP. MATERIALS AND METHODS The effectiveness of the lifestyle modification program versus usual care in health-care centers is evaluated in a randomized controlled trial. Patients aged 30years or older having a systolic blood pressure(SBP) of 140-179mmHg or a diastolic blood pressure(DBP) of 90-109 mm Hg or patients taking antihypertensive medications are eligible for the study. -The primary outcomes measured are SBP and DBP levels. Mediator outcomes include physical activity level, stress scale, dietary composition, and weight measurements. All measurements will be conducted after the 4weeks of intervention and also at 6months. CONCLUSION Outcomes of the study will present the effects of implementing multicomponent lifestyle intervention programs to control BP in health-care centers settings.

Abstract
BACKGROUND Increasing prevalence of obesity is a major health concern. Lifestyle behaviors and diet play an important role in developing childhood obesity. The aim of this study was to determine the association between major dietary patterns and overweight/obesity in a group of Iranian school-aged children. METHODS This cross-sectional study was conducted in Isfahan, Iran with 637 elementary school-aged children. A semi-quantitative food-frequency questionnaire was used to assess usual dietary intakes. Data on socio-demographic, physical activity and other lifestyle habits were collected using standard questionnaires. Obesity was determined based on national cut-offs. Factor analysis was used for identifying major dietary patterns. RESULTS Three major dietary patterns were extracted; "Healthy," "Western," and "Sweet-Dairy." After adjusting for confounders, girls in the second quartile of healthy pattern, were more likely to be overweight (odds ratio [OR] =2.23, Confidence intervals [CI] =1.003, 4.96) compared to those in the highest quartile. Likelihood of being overweight was lower for girls in the second quartile of western dietary pattern versus the fourth quartile (OR = 0.46, CI = 0.21, 1.01). Accordingly, lower adherence to sweet and dairy pattern was associated with lower body mass index (BMI) among girls (OR = 0.42, CI = 0.21, 0.85). There was no significant relationship between western and sweet-dairy pattern with BMI among boys, however, significant association was observed between lowest and highest quartiles of healthy pattern (OR = 0.36, CI = 0.15, 0.84). CONCLUSIONS We found significant associations between the three dietary patterns and obesity among girls. Only healthy pattern was related to weight status of schoolboys. Longitudinal studies will be needed to confirm these associations.

Abstract
BACKGROUND Flavonoids comprise a large group of plant metabolites, 6,000 of which have been identified to date. Some studies have shown the increased aerobic performance and maximal oxygen consumption (VO(2max)) and therefore fitness following quercetin intake as a result of elevated number of intracellular mitochondria caused by the flavonoid. METHODS This double-blind clinical trial comprised 60 male students having an athletic history of at least 3 years. Body composition, exercise performance, and some blood biomarkers were analyzed. The individuals were selected by convenient sampling, and then were assigned into four groups of equal number by using permuted block randomization. The first to fourth groups received a 500 mg supplemental quercetin capsule plus a 250 mg vitamin C pill, a 500 mg supplemental quercetin capsule plus a 250 mg placebo vitamin C pill, a 500 mg placebo quercetin capsule plus a 250 mg vitamin C pill, and a 500 mg placebo quercetin capsule plus a 250 mg placebo vitamin C pill, respectively, daily for 8 weeks. The participants were asked to continue their routine diet and physical activity during the study and they were monitored through phone calls or text messages. RESULTS Lean body mass, total body water, basal metabolic rate, and total energy expenditure increased significantly in the quercetin group after intervention. On the other hand, VO(2max) increased in the "quercetin" and "quercetin + vitamin C" groups following the intervention, non-significantly. CONCLUSION Our findings suggest that supplementation with quercetin in athletes may improve some indices of performance.

Abstract
BACKGROUND Quercetin is a bioflavonoid occurs in many food items. Some previous studies on quercetin showed the inconsistent results on exercise performance and muscle damage in athletes. The aim of this study was to determine the effects of 8 weeks of quercetin supplementation on exercise performance and muscle damage indices in student athletes. METHODS This placebo-controlled, double-blind clinical trial was conducted on 60 male students for 8 weeks. The subjects were randomly assigned to one of the four groups: a) quercetin (500 mg/day quercetin + 200 mg/day placebo), b) quercetin+ vitamin C (500 mg/day quercetin + 200 mg/day vitamin C), vitamin C (500 mg/day placebo + 200 mg/day vitamin C), and placebo (500 mg/day placebo + 200 mg/day placebo). Time to exhaustion (TTE) for measuring performance, aspartate transaminase (AST), and creatine kinase (CK) for measuring muscle damage and body fat percent (BFP) were measured before and after intervention. RESULTS CK levels reduced in group 1 significantly (P=0.045) and BFP reduced in group 1, 3, and 4, significantly, too (P=0.018, P=0.013, and P=0.043, respectively). Whereas statistically significant changes between groups were not observed for TTE, AST, CK, and BFP after 8 weeks of intervention. CONCLUSIONS Supplementation with quercetin and vitamin C for 8 weeks did not improve exercise performance but reduced muscle damage and body fat percent in healthy subjects.
