Food Habits Related To Osteoporosis in Women in Iran

0TBackground: 0TOsteoporosis is an important public health problem. The aim of this study was to investigate food habits and 0Tsome factors related to0T osteoporosis in women in Iran.Methods: This cross-sectional study was conducted on 399 childbearing age women who were attending health centers and 200 healthcare providers in 2007. Food habits and dietary calcium intake was evaluated by food frequency questionnaire and 24-hour recall method. Weight and height of subjects were also measured. Independent t-test, Mann-withney U test, 0TPearson, Spearman and 0TPartial0T correlation coefficient tests 0Twere used for analyzing of data.Results: Two groups of women had calcium intake deficiency. Daily frequency of milk, cheese, fruit and coffee consumptions in healthcare providers (0.82±0.82, 0.94±0.49, 2.01±1.28 and 0.84±2.05, P<0.02) were significantly higher than those of women attending health centers(0.58±0.72, 0.84±0.32, 1.50±0.99 and 0.48±1.25). Mean frequency use of dark vegetables, cola and pickles were significantly (P<0.004) higher in women who attending health centers (0.67±0.50, 1.55±2.36 and 1.92±2.03) than those of the other group (0.50±0.44, 1.09±2.65 and 1.49±1.72). In women who were attending health centers, negative and posi-tive significant relationship was found between daily calcium intake with age (P<0.04) and educational level (P<0.001). No significant relationship was found between body mass index with studied variables.Conclusion: Women of health care providers had healthier food habits compared to women who attending health centers. Educational programs are suggested to improve food habits among women to prevent osteoporosis in later life

Impact of Vitamin E Supplementation on Blood Pressure and Hs-CRP in Type 2 Diabetic Patients

Background: Type 2 diabetes mellitus (T2DM) is a major public health problem worldwide.Hypertension and inflammation are well recognized as risk factors for the macrovascular complicationsof diabetes. The aim of this study was to assess the impact of vitamin E supplementationon blood pressure (BP), serum high-sensitivity C-reactive protein (hs-CRP) and fasting bloodglucose in patients with T2DM.Methods: In a double blind, randomized, controlled clinical trial, 83 patients with T2DM weredivided randomly into two groups of vitamin E (400 mg/d, n=42) and placebo (n=41). All patientsreceived the pearls for 8 weeks. Baseline and eighth week BP, serum hs-CRP, fasting bloodglucose, anthropometric and dietary intake data were obtained from each patient. Data were analyzedusing SPSS version 11.5.Results: Vitamin E supplementation significantly increased serum levels of vitamin E (P <0.001) and decreased mean arterial pressure and fasting blood glucose (P = 0.047, P = 0.028, respectively)in vitamin E group as compared with placebo group. A significant decrease in systolicblood pressure and diastolic blood pressure was observed in the vitamin E group comparing withbaseline values (all P < 0.01). There were no significant changes in serum hs-CRP in both of thestudied groups.Conclusion: Vitamin E had beneficial effects on serum vitamin E, BP and blood glucose in patientswith T2DM. Improvement in BP and glucose control may contribute to reducing complicationsof diabetes including cardiovascular risk in these patients

Evaluation of cardiovascular risk factors in women referring to health centers in Tabriz, Iran, 2017

Background: Cardiovascular disease (CVD) is the leading cause of mortality among men and women around the world. The aim of this study was to investigate major cardiovascular risk factors in women living in the Tabriz petrochemical region, Iran during spring 2017.Methods: In this cross-sectional study, a sample of 152 women aged 30-55 years was selected from who attended health center in Tabriz, Iran. Anthropometric measurements, blood pressure,daily dietary intakes and fasting serum lipid profile, oxidized LDL (ox-LDL) and high sensitivity C-reactive protein (hs-CRP) were evaluated.Results: The prevalence of overweight, general and abdominal obesity (based on Body mass index [BMI] and waist circumference [WC]) was 34.2%, 52.6%, and 73.7%, respectively. Eleven point two percent and 4.6% of women had pre-hypertension based on systolic blood pressure (SBP)and diastolic blood pressure (DBP). High serum triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and low high-density lipoprotein cholesterol (HDL-C)were determined in 32.5%, 25.7%, 17.8% and 56.6% of subjects, respectively. The median of serum ox-LDL concentration was 3181.5 ng/L. Sixty-five point eight percent of participants hadhigh hs-CRP levels. In the multiple-adjusted quintile regression analysis, significant relationships were found between serum ox-LDL and age (B = 96.7, P = 0.003) and between serum hs-CRP with diastolic blood pressure (B = 0.1, P = 0.083) and TG (B = 0.01, P = 0.088).Conclusion: The high prevalence of cardiovascular risk factors in the studied women warrants more public health attention. The results also suggest that aging was associated with high serumox-LDL and increased serum hs-CRP levels, which may reflect enhanced DBP and serum TG

Effects of Pharmacologic Dose of Resveratrol Supplementation on Oxidative/Antioxidative Status Biomarkers in Nonalcoholic Fatty Liver Disease Patients: A Randomized, Double-Blind, Placebo-Controlled Trial

Purpose: Despite a proposed role for oxidative stress in the pathogenesis of nonalcoholic fatty liver disease (NAFLD), antioxidant approaches have not been sufficiently investigated in human NAFLD management. Resveratrol has been reported to possess a wide range of biological functions, including antioxidant activities. This study aimed to evaluate the effects of resveratrol supplementation on oxidative/anti-oxidative status in patients with NAFLD. Methods: This randomized, double-blind, placebo-controlled clinical trial was conducted on 60 patients with NAFLD (males and females) aged 20 to 60 years, and body mass index (BMI) of 25-35 kg/m2. Subjects were randomly assigned to receive a daily dose of 600 mg resveratrol (2×300 mg pure trans-resveratrol capsules; n=30) or placebo capsules (n=30) for 12 wk. Fasting blood samples, anthropometric measurements, and dietary intakes were collected for all patients at baseline and at the end of the trial. Oxidative stress was evaluated by measurement of serum malondialdehyde (MDA), oxidized low-density lipoprotein (ox-LDL), total antioxidant capacity (TAC), and erythrocyte superoxide dismutase (SOD) as well as glutathione peroxidase (GSH-Px) activities. Changes in the outcomes were analyzed using analysis of covariance (ANCOVA). Results: Resveratrol supplementation did not significantly affect neither serum MDA, ox-LDL, and TAC levels, nor erythrocyte SOD and GSH-Px activities, compared to placebo group (All P>0.05). Moreover, changes in serum levels of liver enzymes (ALT, AST, GGT, and ALP) were not significant in neither of the study groups (All P>0.05). Conclusion: Resveratrol supplementation did not modify oxidative/anti-oxidative status in patients with NAFLD

Assessment of atherogenic indices and lipid ratios in the apparently healthy women aged 30–55 years

Background: Cardiovascular disease (CVD) is the main cause of death worldwide and atherogenic dyslipidemia is an established risk factor for CVD. This cross-sectional study aimed to assess the atherogenic indices and lipid ratios, including atherogenic coefficient (AC), atherogenic index of plasma (AIP), cholindex (CI), Castelli risk index-1 (CRI-1), CRI-2, and non-HDL-C, in women living in the Tabriz, Iran during April–May 2017. Material and methods: Anthropometric measurements, fasting serum lipids, and blood pressure of 150 women aged 30–55 years in Tabriz, Iran was evaluated. The atherogenic indices were calculated by the established formulas. Results: The prevalence of high AIP, AC, CI, CRI-1, CRI-2 and non-HDL-C ratios were 64.5%, 36.2%, 20.4%, 77%, 7.2% and 44.7%, respectively. In the multiple-adjusted quantile regression analysis, significant relationships were found between CI ratio and diastolic blood pressure (DBP) (B = 3.76, p = 0.035) and between CRI-2 ratio and DBP (B = 0.005, p = 0.042) and age (B = 0.005, p = 0.031). Conclusions: This study indicated that the majority of studied women had a high risk of CVD based on atherogenic indices. Further public health efforts are required to enhance awareness of women and healthcare providers about preventing and controlling CVD risk

Oncopreventive effects of theanine and theobromine on dimethylhydrazine-induced colon cancer model

Theanine and theobromine are abundantly present in tea and cocoa, respectively. This study was performed to assess the chemopreventive effects of these phytochemicals, alone or together, on dimethylhydrazine (DMH)-induced colon cancer. Thirty male Wistar rats were divided into five groups and subcutaneously injected with saline (negative control group) or 30 mg/kg DMH (the other groups) two times/week for 12 weeks. The negative and positive control animals were orally treated with drinking water, and the other groups were gavaged with theanine (400 mg/kg), theobromine (100 mg/kg), or their mixture for two weeks before and throughout the injection period. At the end of the study, the morphological and histopathological features, Ki-67 proliferation marker, and the expression of Akt/mTOR, JAK2/STAT3, MAPK/ERK, and TGF-β/Smad pathways were investigated. Theanine and theobromine, alone or together, reduced the number of cancerous and precancerous lesions, the volume of tumors, the Ki-67 immunostaining, and the expression of Akt/mTOR and JAK2/STAT3 oncogenic pathways. The simultaneous treatment was more effective in the down-regulation of Akt and mTOR compared to either theanine or theobromine alone. Theobromine administration also caused more inhibitory effects on the Ki-67 and Akt/mTOR expression than theanine. Besides, all dietary interventions increased the mRNA and protein expression of Smad2. In conclusion, theanine and theobromine, alone and in combination, inhibited tumorigenesis through down-regulation of the Akt/mTOR and JAK2/STAT3 pathways and an increment of the Smad2 tumor suppressor. The inhibition of the Akt/mTOR pathway was more pronounced by simultaneous treatment

Effects of Calorie Restricted Diet on Oxidative/Antioxidative Status Biomarkers and Serum Fibroblast Growth Factor 21 Levels in Nonalcoholic Fatty Liver Disease Patients: A Randomized, Controlled Clinical Trial

Oxidative stress plays a fundamental role in the development and progression of nonalcoholic fatty liver disease (NAFLD). This study aimed to investigate the effects of a calorie-restricted (CR) diet on oxidative/anti-oxidative status in patients with NAFLD and the potential mediating role of fibroblast growth factor 21 (FGF-21) in this regard. This randomized, controlled clinical trial was carried out on sixty patients with NAFLD aged 20 to 60 years with body mass index (BMI) ranging from 25 to 35 kg/m2. Participants were randomly assigned to either the CR diet group (received a prescribed low-calorie diet for twelve weeks, n = 30) or the control group (n = 30). Fasting blood samples, anthropometric measurements, dietary intake, and physical activity data were collected for all participants at baseline and at the end of the trial. Significant reductions in weight, BMI, waist circumference, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were observed in the CR diet group compared to the control group (all p p > 0.05). CR diet with moderate weight loss has some favorable effects on NAFLD but was not able to modify oxidative/anti-oxidative status in these patients. Future studies are warranted to target the effects of long-term interventions with a greater weight loss in this patient population
