Background Visceral adiposity index (VAI) and atherogenic index of plasma (AIP) are relatively new indicators for predicting non-communicable diseases (NCDs). Therefore, the present study was done to assess the association of AIP and VAI with risk of cardiovascular diseases (CVDs). Methods This cross-sectional study was conducted on 7,362 individuals aged between 35 and 65 years old participated in Ravansar non-communicable diseases (RaNCD) cohort study. AIP was calculated based on levels of triglyceride and high -density lipoprotein cholesterol (HDL-C). VAI was calculated using values of body mass index (BMI), waist circumference (WC), triglyceride, and HDL-C. Logistic regression models were used to assess the association of AIP and VAI with risk of CVDs. Results Mean values of anthropometric indices, lipid profile, AIP, and VAI were significantly higher in patients with CVDs than individuals without CVDs (P < 0.001). Mean values of anthropometric indices, lipid profile, and NCDs including hypertension, dyslipidemia, diabetes, metabolic syndrome (MetS), and CVDs in the third tertile of AIP and VAI were significantly increased compared to the first tertile (P < 0.001). After adjusting confounding factors, risk of CVDs in the third tertile of AIP was (OR = 1.32, 95 % CI: 1.03, 1.69) significantly increased compared to the first tertile. Risk of CVDs in the third tertile of VAI was (OR = 1.48, 95 % CI: 1.12, 1.97) significantly increased compared to the first tertile. Conclusions According to the findings, AIP and VAI were positively associated with risk of CVDs. Therefore, AIP and VAI can be useful in identifying high-risk subgroups of CVDs in general population.

Background Antioxidants intake from diet has been identified as one of the effective factors in the development of hypertension (HTN). The present study aimed to investigate the association between total antioxidant capacity (TAC) and HTN in women. Methods This cross-sectional study was performed using the baseline phase data of the ravansar non-communicable disease cohort study. The TAC was calculated using food items of the food frequency questionnaire. TAC scores were classified into four groups (quartile). The first and fourth quartiles had the lowest and highest TAC scores, respectively. Logistic regression analysis was utilized to estimate the odds ratio. Results A total of 5067 women were included in the study. Women with the highest socioeconomic status (SES) had a significantly higher TAC intake compared to those with the lowest SES (P < 0.001). The participants in the third and fourth quartiles of the TAC had significantly lower odds of HTN, respectively by 21% (OR = 0.79; 95% CI: 0.64, 0.972) and 26% (OR = 0.74; 95% CI: 0.60, 0.91), compared to the first quartile. After adjusting for confounding variables was found to significantly reduce the odds of developing HTN in the fourth quartile of TAC by 22% compared to the first quartile (OR = 0.78; 95% CI: 0.62, 0.97). Conclusion A high dietary TAC was associated to a decreased odd of HTN in women. We could suggest a diet rich in natural antioxidants as it may help prevent development of HTN.

Background: Diet is one of the influential factors in developing hypertension. Moreover, the role of antioxidants in the prevention of cardiovascular diseases (CVDs) has been identified. Total antioxidant capacity (TAC) is a valid tool to assess intake antioxidants from diet. The aim of this study was to examine the association between TAC and hypertension in pre- and postmenopausal women.Methods: In this cross-sectional study was used baseline data of the Ravansar Non-Communicable Disease (RaNCD) cohort study. The TAC was calculated using food items of the food frequency questionnaire. Univariable and multivariable logistic regression were applied to estimates odds ratio. Results: A total of 5,067 women were included in the study. The mean daily intake of refined grains, legumes, white meat, nuts, omega-3, and omega-6, vitamins of B1, B2, B6 and D were significantly higher among women non-hypertensive compared to hypertensive (P<0.05). Multivariate logistic regression showed the odds of hypertension in the third quartile of dietary TAC was 0.71 (95% CI: 0.52, 0.96) times and the fourth quartile of dietary TAC was 0.73 (95% CI: 0.53, 0.98) times lower compared to the first quartile, in pre/perimenopausal women. There was no association between TAC and hypertension in postmenopausal women.Conclusion: A high dietary TAC was associated to a decreased risk of hypertension in pre/perimenopausal women. We suggest a diet rich in natural antioxidants as it may help prevent developing of hypertension before menopausal.

Background: Visceral Adiposity index (VAI) and atherogenic index of plasma (AIP) are relatively new indicators for predicting Non-Communicable disease (NCDs). The aim of this study was to assess the association AIP and VAI with risk of developing cardiovascular diseases (CVDs) in adults.Materials: This was a cross-sectional analysis conducted on 7362 individuals aged 35 to65 years participated in Ravansar Non-Communicable Diseases (RaNCD) cohort study. AIP was calculated based on the value of TG and HDL-C. VAI was calculated using BMI (Body mass index), waist circumference (WC), serum triglyceride, and High density lipoprotein cholesterol (HDL-C).All participants were stratified into three groups based on AIP and VAI tertiles. Simple and multiple logistic regression models were applied to assess the effect of these indices on CVDs.Results: The mean of AIP and VAI was significantly higher in CVDs patients than in non-CVDs (P < 0.001). After adjusting for age, sex hypertension, hyperlipidemia and smoking the risk of CVDs in the second and third tertile of AIP were 1.27 (95% CI: 1.06, 1.52) and 1.63 (95% CI: 1.31, 2.03) times higher comparing to the first tertile, respectively. Risk of CVDs in the second and third tertile of VAI were1.41 (95% CI: 1.18, 1.70) and 1.98 (95% CI: 1.60, 2.46) times higher than the first tertile, respectively; while adjusting for age, sex, hypertension and dyslipidemia.Conclusion: According to the findings, AIP and VAI were positively associated with CVDs in adults. Therefore, AIP and VAI can be useful in identifying high-risk subgroups of CVDs in general population.
