Project description:The aim of the study was to investigate the relationship between specific known dietary patterns and the prevalence of periodontal disease in a northern population-based cohort study. We evaluated data from 6209 participants of the Hamburg City Health Study (HCHS). The HCHS is a prospective cohort study and is registered at ClinicalTrial.gov (NCT03934957). Dietary intake was assessed with the food frequency questionnaire (FFQ2). Periodontal examination included probing depth, gingival recession, plaque index, and bleeding on probing. Descriptive analyses were stratified by periodontitis severity. Ordinal logistic regression models were used to determine the association. Ordinal regression analyses revealed a significant association between higher adherence to the DASH diet/Mediterranean diet and lower odds to be affected by periodontal diseases in an unadjusted model (OR: 0.92; 95% CI: 0.87, 0.97; p < 0.001/OR: 0.93; 95% CI: 0.91, 0.96; p < 0.001) and an adjusted model (age, sex, diabetes) (OR: 0.94; 95% CI: 0.89, 1.00; p < 0.0365/OR: 0.97; 95% CI: 0.94, 1.00; p < 0.0359). The current cross-sectional study identified a significant association between higher adherence to the DASH and Mediterranean diets and lower odds to be affected by periodontal diseases (irrespective of disease severity). Future randomized controlled trials are needed to evaluate to which extent macro- and micronutrition can affect periodontitis initiation/progression.

Project description:The purpose of this study was to examine the association between the dietary antioxidant quality score (DAQS) and the severity of Coronavirus disease 2019 (COVID-19). The present case-control study was carried out on 295 patients diagnosed with COVID-19 (≥18 years old), including 104 critical patients (Intensive care unit [ICU] admission) and 191 COVID-19 patients without severe complications (Non-intensive care unit [Non-ICU] patients) as cases. Dietary intake was assessed by a 147-item, semi-quantitative food frequency questionnaire (FFQ). Logistic regression was performed to calculate the odds ratio (OR) and 95% confidence interval (CI) for the considered risk factors. Our outcomes (after multivariate adjustment) suggested that higher adherence to DAQS was significantly associated with a decreased risk of COVID-19 infection severity (OR = 0.12; 95% CI: 0.04-0.29, p < 0.001). Similar results were seen when analyzed by sex [men (OR = 0.02; 95% CI: 0.002-0.15, p < 0.001) and women (OR = 0.21; 95% CI: 0.06-0.68, p = 0.012)]. A significant association between vitamin D3 intake and decreased risk of COVID-19 severity (OR = 0.91; 95% CI: 0.89-0.94, p < 0.001) was also observed. Moreover, multivariate results revealed that there were no significant associations between vitamin C (OR = 1.00; 95% CI: 0.99-1.00, p = 0.067), vitamin E (OR = 0.98; 95% CI: 0.86-1.11, p = 0.798), zinc (OR = 1.02; 95% CI: 0.86-1.20, p = 0.805), and selenium (OR = 0.99; 95% CI: 0.99-1.00, p = 0.077) intakes with the risk of COVID-19 severity. However, subgroup analyses by sex suggested a significant association between vitamin C intake and the risk of COVID-19 infection severity in women (OR = 1.00; 95% CI: 1.00-1.00, p = 0.028). Our findings showed a negative association between DAQS adherence and the risk of COVID-19 infection severity. Our results may be used to develop potential dietary therapies to decrease COVID-19 severity.

Project description:Study questionIs dietary non-enzymatic antioxidant capacity related to semen quality?Summary answerThe only statistically significant association of semen quality parameters with dietary total antioxidant capacity (DTAC) detected was an inverse association between DTAC and ejaculate volume.What is known alreadyGrowing interest exists regarding the role of diet in influencing semen quality. While DTAC is linked to favorable health outcomes, its association with semen quality, especially among men attending infertility clinics, remains understudied.Study design size durationThis cross-sectional study was carried out between June and December of 2020. In total, 1715 participants were included in the final analysis.Participants/materials setting methodsMen who attended an infertility clinic in China were enrolled. Experienced clinical technicians performed the semen analysis. The DTAC indices included the ferric-reducing ability of plasma, oxygen radical absorbance capacity, total reactive antioxidant potential, and Trolox equivalent antioxidant capacity. The quantile regression model was used for multivariate analysis.Main results and the role of chanceAfter adjustment for a variety of confounding variables, a significant inverse association was identified between DTAC and ejaculate volume (βcontinuous FRAP = -0.015, 95% CI = -0.023, -0.006, βT3 vs T1 = -0.193, 95% CI = -0.379, -0.006, Ptrend = 0.007; βcontinuous TRAP = -0.019, 95% CI = -0.041, 0.002, βT3 vs T1 = -0.291, 95% CI = -0.469, -0.112, Ptrend = 0.002). The majority of DTAC indices have no statistically significant association with semen quality parameters.Limitations reasons for cautionWe cannot infer causality because of the nature of the cross-sectional study design. The robustness of the conclusion may be compromised by the exactness of non-enzymatic antioxidant capacity estimation.Wider implications of the findingsOur findings demonstrated no association between DTAC indices and semen quality parameters among men attending an infertility clinic, except for ejaculate volume. Even though our findings are mostly non-significant, they contribute novel knowledge to the field of study while also laying the groundwork for future well-designed studies.Study funding/competing interestsThis work was supported by the JieBangGuaShuai Project of Liaoning Province [grant number 2021JH1/10400050], the Clinical Research Cultivation Project of Shengjing Hospital [grant number M1590], and the Outstanding Scientific Fund of Shengjing Hospital [grant number M1150].

Project description:Inflammation-modulating elements are recognized periodontitis (PD) risk factors, nevertheless, the association between dietary inflammatory index (DII) and PD has never been appraised. We aimed to assess the association between DII and PD and the mediation effect of DII in the association of PD with systemic inflammation. Using the National Health and Nutrition Examination Survey 2009-2010, 2011-2012 and 2013-2014, participants who received periodontal exam and provided dietary recall data were included. The inflammatory potential of diet was calculated via DII. PD was defined according to the 2012 case definition. White blood cells (WBC), segmented neutrophils and C-reactive protein (CRP) were used as proxies for systemic inflammation. The periodontal measures were regressed across DII values using adjusted multivariate linear regression and adjusted mediation analysis. Overall, 10,178 participants were included. DII was significantly correlated with mean periodontal probing depth (PPD), mean clinical attachment loss (CAL), thresholds of PPD and CAL, WBC, segmented neutrophils and DII (p < 0.01). A linear regression logistic adjusted for multiple confounding variables confirmed the association between DII and mean PPD (B = 0.02, Standard Error [SE]: 0.02, p < 0.001) and CAL (B = -0.02, SE: 0.01, p < 0.001). The association of mean PPD and mean CAL with both WBC and segmented neutrophils were mediated by DII (from 2.1 to 3.5%, p < 0.001). In the 2009-2010 subset, the association of mean CAL with serum CRP was mediated by DII (52.0%, p < 0.01). Inflammatory diet and PD may be associated. Also, the inflammatory diet significantly mediated the association of leukocyte counts and systemic inflammation with PD.

Project description:BackgroundIndividual antioxidants may not fully capture the comprehensive antioxidant intake from an individual's diet. This study utilizes the Complex Dietary Antioxidant Index (CDAI) to evaluate the combined effects of various dietary antioxidants in the diet. The goal is to investigate the relationship between CDAI and the incidence of erectile dysfunction (ED), offering insights for dietary guidelines and intervention strategies aimed at mitigating the burden of ED.MethodsThis cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) database in the years 2001-2004. We employed a weighted multivariate logistic regression model to validate the relationship between CDAI and ED. Subgroup analyses were conducted to explore the correlation between CDAI and ED across different subgroups. Additionally, we used propensity score matching (PSM) to adjust for several key confounding variables, enhancing the robustness of the results.ResultsIn the fully adjusted multivariate logistic regression model for confounding variables, CDAI is negatively correlated with the risk of ED (OR = 0.95, 95% CI: 0.92-0.99, P = 0.005). When CDAI is transformed into a categorical variable based on quartiles, Q3 (OR = 0.73, 95% CI: 0.53-0.99, P = 0.040) and Q4 (OR = 0.70, 95% CI: 0.51-0.96, P = 0.026) show a negative correlation with the risk of ED. Subgroup analysis reveals no significant interaction. After adjusting for major confounding variables through PSM, the association between CDAI and reduced risk of ED remains significant.ConclusionIn our study cohort, there is an association between CDAI and a reduced risk of ED, and further research is needed to validate and refine this conclusion.

Project description:Genetic and environmental risk factors contribute to periodontal disease, but the underlying susceptibility pathways are not fully understood. Epigenetic mechanisms are malleable regulators of gene function that can change in response to genetic and environmental stimuli, thereby providing a potential mechanism mediating risk effects in periodontitis. The aim of this study is to identify epigenetic changes across tissues that are associated with periodontal disease.

Project description:BackgroundConstipation seriously affects people's life quality, and dietary adjustment has been one of the effective methods. Overall dietary quality has been reported to be associated with some diseases, while its association with constipation has not been reported. This study aims to explore the association between overall dietary quality and constipation.MethodsA cross-sectional study was designed and data were extracted from National Health and Nutrition Examination Survey (NHANES). Overall dietary quality was assessed by healthy eating index-2015 (HEI-2015), and constipation was defined by either stool consistency or stool frequency. The association between overall dietary quality or components of HEI-2015 and constipation was assessed using logistic regression, with results expressed as odds ratio (OR) and 95% confidence intervals (95%CI). Subgroup analysis was conducted according to age and gender.ResultsA total of 13,945 participants were eligible, with 1,407 in constipation group and 12,538 in non-constipation group. Results showed that higher adherence to HEI-2015 was associated with reduced odds of constipation (OR: 0.98, 95%CI: 0.98-0.99) after adjusting potential confounders. Further, we found higher intake of total fruits, whole fruits, total vegetables, greens and beans, whole grains, total protein foods, seafood and plant proteins, and higher fatty acids ratio decreased the odds of constipation, while higher intake of sodium increased the odds (all P < 0.05). We also found negative association between HEI-2015 and constipation in participants with male sex, female sex, age ≥ 65 years, and age < 65 years (all P < 0.05).ConclusionWe found higher adherence to HEI-2015 decreased the odds of constipation, suggesting that increasing HEI-2015 adherence may be one of effective methods to alleviate constipation.

Project description:BackgroundErectile dysfunction (ED) is a common issue among adult males. The Composite Dietary Antioxidant Index (CDAI) reflects anti-inflammatory levels and has been linked to various diseases, but its relationship with ED is unclear.Materials and methodsThis cross-sectional study utilised comprehensive data on clinical factors from the 2001-2004 National Health and Nutrition Examination Survey (NHANES). To investigate the link between variables and ED, we used multivariate regression analysis, univariate analysis, and subgroup analysis. The linear relationship between CDAI and ED was investigated by dose-response curve analysis. For sensitivity analysis, propensity score matching (PSM) was utilised to exclude the influence of potential confounders. Finally, we investigated the association between CDAI and ED using threshold effects analysis.ResultsWe included in our research a total of 2896 persons with data on CDAI from NHANES 2001-2004. Among these, 2,098 participants were thought to be free of ED, whereas 798 participants had ED. We found that compared to the ED group, men in the non-ED group had higher levels of CDAI (p < 0.0001 before PSM and p = 0.0145 after PSM). Additionally, after adjusting for covariates, it was found that an elevated CDAI was associated with a reduced incidence of ED [OR = 0.65(p = 0.001) before PSM and OR = 0.62(p = 0.002) after PSM]. Subgroup analysis indicated stronger associations in high-risk groups, and dose-response curves confirmed a linear negative correlation between CDAI and ED.ConclusionsThis study revealed a negative linear relationship between CDAI and the incidence of ED. The CDAI can be used as an indicator for assessing ED risk and for ED prevention.

Project description:BackgroundEpilepsy is a major global health challenge, affecting approximately 50 million people across the globe and resulting in significant economic impacts on individuals and society. Oxidative stress is implicated in the pathogenesis of epilepsy, highlighting the potential of antioxidant-rich dietary patterns in offering preventive and protective benefits by mitigating oxidative stress. The Composite Dietary Antioxidant Index (CDAI) provides a measure for assessing dietary antioxidant intake, yet its link to epilepsy remains unexplored.MethodsOur analysis utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning 2013 to 2018, including 20,180 screened participants. Weighted logistic regression models were employed to examine the association between the CDAI and epilepsy prevalence. Non-linear associations were explored through restricted cubic splines (RCS), and the relationships between individual antioxidant components within the CDAI and epilepsy were also assessed.ResultsAfter adjusting for potential confounders, a negative association between the CDAI and epilepsy was suggested (OR = 0.991; p = 0.087, 95% CI [0.819,1.014]). Stratification of CDAI into quartiles revealed a significantly reduced risk of epilepsy in higher CDAI quartiles (Q3 and Q4) compared to the lowest quartile (Q1) (Q3: OR = 0.419; p = 0.030, 95% CI [0.192, 0.914]; Q4: OR = 0.421; p = 0.004, 95% CI [0.239, 0.742]), with a significant trend observed across quartiles (p for trend = 0.013). RCS analysis suggested a nonlinear association between CDAI levels and epilepsy (non-linear p = 0.049), which, however, was not statistically significant after full adjustment (non-linear p = 0.103). Additionally, significant negative correlations with epilepsy were observed for vitamin A and zinc (Vitamin A: OR = 0.999; p = 0.012, 95% CI [0.998, 1.000]; Zinc: OR = 0.931; p = 0.042, 95% CI [0.869, 0.997]).ConclusionsOur research indicates a correlation where higher CDAI levels correspond to a reduced risk of epilepsy. Therefore, embracing a diet rich in antioxidants could be beneficial in preventing epilepsy. This finding holds considerable potential for shaping future strategies in both epilepsy prevention and treatment.

Project description:No study has investigated the relationship between dietary total antioxidant capacity and sarcopenia so far. This study aimed to investigate the association between dietary Total Antioxidant Capacity (d-TAC) and sarcopenia in elderly adults. In this cross-sectional study we enrolled 300 elderly people (150 men and 150 women) aged ≥ 55 years using cluster random sampling method. Sarcopenia was defined based on European Working Group on Sarcopenia (EWGSOP) definition. A DXA scanner, a squeeze bulb dynamometer and a 4-Meter walk gait speed test was used to measure Appendicular Skeletal Muscle (ASM), muscle strength and muscle performance respectively. We also used a Block-format 117-item food frequency questionnaire (FFQ) to assess dietary intakes of participants. Multivariable logistic regression models were applied to examine the association between d-TAC and sarcopenia. Mean ± SD age of study participants and their BMI was 66.8 ± 7.72 year and 27.3 ± 4.2 kg/m2, respectively. People in the highest tertile of d-TAC had the greatest hand grip strength (11.9 ± 3.63 vs. 10.4 ± 3.55 psi, p = 0.009) and had lower odds of sarcopenia compared with those in the lowest tertile, either before (OR = 0.39; 95% CI: 0.17, 0.88) or after adjustment for potential confounders (OR = 0.33; 95% CI: 0.11, 0.95). No other significant association was seen between d-TAC and components of sarcopenia. We found an inverse association between dietary total antioxidant capacity and odds of sarcopenia. No significant association was seen between d-TAC and individual components of sarcopenia. Further studies are needed to confirm our findings.
