Abstract
The composite dietary antioxidant index (CDAI) is indeed a valuable nutritional tool used to evaluate the overall antioxidant capacity of an individual's daily food consumption. The CDAI was calculated from the intake of six antioxidant components in the diet, including vitamin A, vitamin C and vitamin E, carotenoids, selenium, and zinc. This study aimed to determine the association between CDAI and stroke. Utilizing data from the 2003-2018 NHANES dataset, CDAI was computed by summarizing the intake of six dietary antioxidants based on 24-hour dietary recall interviews. The relationship between CDAI and stroke was examined using multivariate logistic regression and restricted cubic spline analysis. This study ultimately included 39,432 participants, of whom 1,527 (3.87%) had a stroke. The multivariate logistic regression model 3 that fully adjusted all confounding variables showed a negative association between CDAI and stroke (OR = 0.97; 95% CI:0.95, 0.99). The highest tertile of CDAI saw a 23% drop in the prevalence of stroke compared to the lowest tertile (OR = 0.77; 95%CI: 0.64,0.92). Restricted cubic spline suggested that this negative correlation was nonlinear with an inflection point of -2.99. Subgroup analyses and interaction tests showed that this negative correlation was more applicable in patients with prediabetes (P < 0.05). There was a non-linear negative correlation between CDAI level and stroke prevalence, and this correlation was more significant in people with pre-diabetes. Appropriate CDAI levels may contribute to the management of stroke risk.

High composite dietary antioxidant index is associated with reduced risk of kidney stones: a cross-sectional analysis of NHANES 2007-2020. Nutr Res 2024; 128:60-69. [PMID: 39059059 DOI: 10.1016/j.nutres.2024.06.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 06/17/2024] [Accepted: 06/17/2024] [Indexed: 07/28/2024]
Abstract
The composite dietary antioxidant index (CDAI) is commonly utilized to assess antioxidant intake across diseases, but its association with kidney stones is unclear. We hypothesized that higher CDAI is associated with reduced kidney stone risk. Using National Health and Nutrition Examination Survey 2007-2020 data, we calculated CDAI based on vitamins A, C, E, selenium, zinc, and carotenoids intake in 29,280 adults. Stone formers had lower CDAI, with significant gender differences. Restricted cubic spline showed an L-shaped curve, with the steepest decline before CDAI of 1.449. In multivariate logistic regression, moderate and high CDAI tertiles were associated with reduced kidney stone odds compared to the lowest tertile (odds ratio [95% CI]): 0.85 [0.73, 0.99], P = .035 and 0.80 [0.66, 0.95], P = .014, respectively). Vitamin C had the highest negative correlation weight with kidney stones. Significant interactions were found for age and diabetes subgroups. In conclusion, higher CDAI may reduce kidney stone risk, especially with adequate vitamin C intake. Further cohort studies are warranted to confirm the causal association.

Cui A, Yan J, Zeng Y, Shi B, Cheng L, Deng H, Wei X, Zhuang Y. Association between composite dietary antioxidant and bone mineral density in children and adolescents aged 8-19 years: findings from NHANES. Sci Rep 2024; 14:15849. [PMID: 38982172 PMCID: PMC11233598 DOI: 10.1038/s41598-024-66859-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 07/04/2024] [Indexed: 07/11/2024] Open
Abstract
Dietary antioxidants may have beneficial effects on bone health, but it remains uncertain in children and adolescents. This study investigates the association of composite dietary antioxidant index (CDAI) with bone mineral density (BMD) in children and adolescents aged 8-19 years from the National Health and Nutrition Examination Survey (NHANES) 2007-2010. The study assessed the relationship between CDAI and BMD in 2994 individuals aged 8-19 years (average age 13.48 ± 3.32 years) from the NHANES 2007-2010. Multivariate linear regression analyses were utilized to detect the association between CDAI and total spine, femur neck, and total femur BMD, adjusting for confounders including age, race/ethnicity, sex, poverty income ratio (PIR), body mass index (BMI), serum phosphorus and calcium. Stratified analyses and interaction tests were performed to examine the stability of the results. The weighted characteristics showed that subjects in the fourth CDAI quartile were more likely to be older, men, and Non-Hispanic White. They have higher values of serum total calcium and phosphorus. After adjusting all confounders, CDAI was positively associated with the total spine (β = 0.0031 95% CI 0.0021-0.0040), total femur (β = 0.0039 95% CI 0.0028-0.0049), and femur neck BMD (β = 0.0031 95% CI 0.0021-0.0040) in children and adolescents. Furthermore, we found no interaction effects between different race/ethnicity, age, and sex groups. Our findings suggest that dietary intake of multiple antioxidants was positively associated with BMD in children and adolescents. These findings provide valuable evidence for improving bone health in the early stages of life. However, more prospective studies are required to validate our findings and their causal relationship.

Qiao Q, Liu X, Xue W, Chen L, Hou X. Analysis of the association between high antioxidant diet and lifestyle habits and diabetic retinopathy based on NHANES cross-sectional study. Sci Rep 2024; 14:11868. [PMID: 38789523 PMCID: PMC11126608 DOI: 10.1038/s41598-024-62707-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 05/21/2024] [Indexed: 05/26/2024] Open
Abstract
Oxidative stress plays a crucial role in increasing the risk of developing diabetic retinopathy (DR). The oxidative balance score (OBS) and the composite dietary antioxidant index (CDAI) are two tools for assessing the effects of diet and lifestyle on oxidative stress. The aim of this study was to investigate the association between OBS, CDAI and the occurrence of DR. After controlling for potential confounders, OBS was negatively associated with DR with an odds ratio (OR) of 0.976 and a 95% confidence interval (CI) of 0.956-0.996, suggesting that for every unit increase in OBS, the risk of DR was reduced by 2.4%. In contrast, the relationship between OBS and CDAI was not significant (P > 0.05), suggesting that it was OBS, not CDAI, that contributed to the reduced risk of diabetic retinopathy. After adjusting for potential confounders, OBS was negatively associated with DR (OR: 0.976; 95% CI 0.956-0.996), but this association was not found in CDAI (P > 0.05), suggesting that for every one-unit increase in OBS, there was a 2.4% reduction in the risk of developing DR. This study suggests that a diet and lifestyle high in OBS reduces the risk of developing DR, which provides a rationale for nutritional interventions to prevent DR.
