Interactions Between Genetic Risk Score and Healthy Plant Diet Index on Cardiometabolic Risk Factors Among Obese and Overweight Women.

People with higher genetic predisposition to obesity are more susceptible to cardiovascular diseases (CVDs) and healthy plant-based foods may be associated with reduced risks of obesity and other metabolic markers. We investigated whether healthy plant-foods-rich dietary patterns might have inverse associations with cardiometabolic risk factors in participants at genetically elevated risk of obesity. For this cross-sectional study, 377 obese and overweight women were chosen from health centers in Tehran, Iran. We calculated a healthy plant-based diet index (h-PDI) in which healthy plant foods received positive scores, and unhealthy plant and animal foods received reversed scores. A genetic risk score (GRS) was developed based on 3 polymorphisms. The interaction between GRS and h-PDI on cardiometabolic traits was analyzed using a generalized linear model (GLM). We found significant interactions between GRS and h-PDI on body mass index (BMI) (p = 0.02), body fat mass (p = 0.04), and waist circumference (p = 0.056). There were significant gene-diet interactions for healthful plant-derived diets and BMI-GRS on high-sensitivity C-reactive protein (p = 0.03), aspartate aminotransferase (p = 0.04), alanine transaminase (p = 0.05), insulin (p = 0.04), and plasminogen activator inhibitor 1 (p = 0.002). Adherence to h-PDI was more strongly related to decreased levels of the aforementioned markers among participants in the second or top tertile of GRS than those with low GRS. These results highlight that following a plant-based dietary pattern considering genetics appears to be a protective factor against the risks of cardiometabolic abnormalities.

The association between dietary pattern and visceral adiposity index, triglyceride-glucose index, inflammation, and body composition among Iranian overweight and obese women.

The aim of the present study was to investigate the association between dietary patterns, derived through latent class analysis (LCA), with visceral adiposity index (VAI), Triglyceride-Glucose Index (TyG), inflammation biomarkers, and body composition in overweight and obese Iranian women. For this cross-sectional study, dietary exposure was assessed using a validated 147-item semi-quantitative food frequency questionnaire (FFQ). Dietary patterns were derived through LCA. Binary logistic was performed to test the associations of dietary patterns with VAI, TyG, inflammation biomarkers, and body composition. Health centers in Tehran, Iran. 376 obese and overweight women, aged > 18 years. Two dietary patterns were identified using LCA modeling: healthy and unhealthy. Women in the unhealthy class were characterized by higher consumption of fast food, sweetened beverages, grains, unhealthy oils, butter and margarine, and snacks. Compared with the healthy class, the unhealthy class was associated with an increased risk of higher fasting blood sugar (FBS) (OR = 6.07; 95% CI: 1.33-27.74, P value = 0.02), c-reactive protein (CRP) (OR = 1.72; 95% CI: 1.05-2.80; P value = 0.02), and lower fat free mass index (FFMI) (OR = 0.56; 95% CI: 0.35-0.88, P value = 0.01), after adjusting for confounders. We found that adherence to an unhealthy dietary pattern was associated with decreased FFMI and increased FBS and CRP using LCA, but not with the rest of the variables. Further studies should be conducted to confirm the veracity of these findings.

The relationship of genetic risk score with cardiometabolic risk factors: a cross-sectional study.

BACKGROUND & AIMS: For more than eight decades, cardiovascular disease (CVD) has remained the leading cause of death in the world. CVD risk factors are multifaceted, with genetics and lifestyle both playing a role. The aim of this study was to investigate the association between a genetic profile risk score for obesity GRS and cardio-metabolic risk factors in overweight and obese women. METHODS: The current cross-sectional study was conducted on 391 overweight and obese women. The genetic risk score was created by combining three single nucleotide polymorphisms [MC4R (rs17782313), CAV-1 (rs3807992), and Cry-1 (rs2287161)]. Anthropometric measurements, blood pressure, and some blood parameters were measured by standard protocols. RESULTS: A significant association between the GRS and some of cardiometabolic risk factors variables such as body mass index (ß = 0. 49, 95%CI = 0.22 to 0.76, p < 0.001), waist circumference (ß = 0. 86, 95%CI = 0.18 to 1.54, p = 0.01), body fat mass (ß = 0. 82, 95%CI = 0.25 to 1.39, p = 0.005), %body fat (ß = 0. 44, 95%CI = 0.06 to 0.82, p = 0.02), and hs-CRP (ß = 0.46, 95% CI = 0.14 to 0.78, p = 0.005) was observed in crude model. After adjustment for confounding factors (age, BMI, and physical activity), a significant positive association was observed between BMI (p = 0.004), WC (p = 0.02), body fat mass (p = 0.01), %BF (p = 0.01), hs-CRP (p = 0.009), and GRS. In addition, we discovered a significant negative association between the GRS and BMC (= -0.02, 95%CI = -0.05 to -0.001, p = 0.04). But other variables did not show any significant association with GRS among obese and overweight women. CONCLUSION: We found a significant positive association between GRS, including MC4R (rs17782313), CAV-1 (rs3807992), and Cry-1 (rs2287161) and cardiometabolic risk factors among overweight and obese Iranian women.

Effect of Vitamin D Supplementation on Inflammatory Biomarkers in School-Aged Children with Attention Deficit Hyperactivity Disorder.

Method: This randomized double-blind, placebo-controlled trial was conducted on 75 school-aged children with a diagnosis of ADHD based on DSM-V criteria. Children were randomly allocated to receive either vitamin D3 (2000 IU/day) or a placebo for 3 months. Serum IL-6, TNF-α, and 25(OH) D were assessed before and after the intervention to determine the effects of vitamin D on the highlighted parameters. Results: Serum levels of 25(OH) D increased significantly in the vitamin D group (P=0.01). However, no significant differences in serum IL-6 and TNF-α were found between both groups at the baseline and at the end of the intervention. Conclusion: The findings revealed that vitamin D supplementation for 3 months is not efficacious in reducing inflammatory cytokines in children with ADHD. Further studies are required to confirm these results.

Effect of Vitamin D on Paraxonase-1, Total Antioxidant Capacity, and 8-Isoprostan in Children with Attention Deficit Hyperactivity Disorder.

Method: In this double-blind, randomized, placebo-controlled trial, 75 children (aged 6-12) diagnosed with ADHD were randomly assigned into two groups. The supplementation group received vitamin D3 (2000 IU), and the control group received a placebo for 3 months. Blood samples were collected at baseline and after intervention to analyze the 25(OH)D, paraxonase-1 activity (PON-1), Total Antioxidant Capacity (TAC), and 8-isoprostan levels. Results: A significant rise in circulating 25(OH)D was observed in the vitamin D group versus the placebo group at the end of the study. There was no reduction in 8-isoprostan levels in the vitamin D group compared to the placebo group. Serum paraxonase-1 and TAC concentration decreased in both groups, but these alterations were not statistically significant in the treatment group versus the placebo group at the end of the intervention. Conclusion: Vitamin D supplementation for 3 months did not have beneficial effects on biomarkers of oxidative stress status. To confirm these findings, further studies on children are suggested.

The association between sarcopenic obesity (SO) and major dietary patterns in overweight and obese adult women.

AIM: No studies have evaluated the contribution of major dietary patterns to Sarcopenic Obesity (SO) in obese and overweight people based on quintile of skeletal muscle mass (SMM) and fat mass (FM). This study was conducted to examine the association between major dietary patterns and SO. METHOD AND MATERIAL: A total of 301 overweight and obese women were included in the cross-sectional study. Body composition was measured by body composition analyzer. Resting metabolic rate was measured by indirect calorimetry. The usual food intake was evaluated by a semi-quantitative FFQ. Serum HDL-c, LDL-c, TG, FBS, total cholesterol and hs-CRP were measured. RESULT: The prevalence of sarcopenia (is referred to as two lower quintiles of SMM) and obesity (is referred to as two highest quintiles of FM) and SO was 19.6%, 20.4% and 9.9% respectively. We used the principal component analysis and three major dietary patterns were determined: the DASH, western and unhealthy dietary pattern, they covering 30.63% of total dietary pattern of our population. Participants in the in the upper category of DASH dietary pattern had lower odds of SO (OR = 0.27, 95% CI = 0.08 to 0.96, P = 0.04). After adjustment for age, physical activity and total energy intake, the association between the DASH and SO, was still significantly negative (OR = 0.20, 95% CI = 0.05 to 0.77, P = 0.01) and the risk of sarcopenia reduced by 80%. CONCLUSION: The present evidence indicates, adherence of the DASH Diet, has a significant effect on reducing the risk of SO.

Adherence to a healthy plant diet may reduce inflammatory factors in obese and overweight women-a cross-sectional study.

OBJECTIVE: Obesity and overweight which are consequence of some interaction factor such as genetics and behavioral habit. Obesity as a metabolic disorder and chronic inflammation is a trigger to countless disease. The main goal of this study is to investigate the interaction of herbal diet on the levels of liver enzymes, inflammatory factors and adipocytes profile. MATERIALS AND METHODS: A total of 240 adult women range of 18-48 years were included in the current comparative cross-sectional study. Body composition and dietary intake (using a validated semi-quantitative food frequency questionnaire (FFQ)) were assessed in all participants. In determining a plant based diet index (PDI), vegetarian foods were taken positive score and reverse points for animal foods. For determining a healthful plant based diet index (hPDI), healthy plant foods received positive scores, while less healthy plant foods and animal foods received reverse scores. To create an unhealthful plant-based diet index (uPDI), positive scores were assigned to less healthy plant foods and reverse scores to healthy plant foods and animal foods. For the measurement of serum liver enzymes and inflammatory factors, an enzyme-linked immunosorbent assay (ELISA) method was used. RESULTS: Healthy diet like whole grains, fruits, vegetables, cereals, and beverages such as tea and coffee, based on dietary guidelines, significantly reduced the amount of hs-CRP and TGF-ß (P < 0.0001). Higher adhering to hPDI may as a result in higher intake of fiber intake, antioxidants, unsaturated fats, micronutrients, could reduce saturated fats and iron content, and finally weight loss, and reduce inflammation in the body. CONCLUSION: Base on our finding, in those people who intake higher amounts of healthy plant foods, (vegetable types), instead of unhealthy herbal foods (sweets and desserts), might be useful to reduce inflammation factor like TGF-ß and hs-CRP. Women with a higher compliance score in uPDI group (juices, refined grains, starches sweetened with sugar, sweets, and desserts) did not have significantly increase in inflammatory factors levels.

Factors Associated With Domestic Violence Against Women in Iran: An Exploratory Multicenter Community-Based Study.

Domestic violence against women committed by intimate partners is a worldwide concern especially in developing countries. The aim of this study was to assess the problem among Iranian women and identify associated risk factors. Using a cross-sectional multicenter design, 1,600 women in six different areas of Iran were surveyed. A measure of domestic violence against women was administered and demographic information collected. Logistic regression models were used to identify factors associated with domestic violence. The prevalence of domestic violence among participants were emotional (64%), physical (28%), and sexual (18%). Higher education (both women and their partners), employment status of partner (being employed), and lower number of children lowered the risk, whereas history of previous marriage (for either women or their partners), unstable marriage, substance abuse, crowded family situation, and lower socioeconomic status increased the risk of domestic violence. There is a high prevalence of domestic violence, particularly emotional, against women by their partners. Preventive measures are recommended such as increasing public awareness, improving in socioeconomic status of families, educating women about what they can do, and encouraging counseling for the couple or the woman alone.
