Dietary niacin Intake and its association with all-cause and cardiovascular mortality rates in individuals with metabolic syndrome.

ABSTRACT:

Background

Individuals with metabolic syndrome face elevated cardiovascular and mortality risks, and there is ongoing debate regarding the cardiovascular effects of niacin and its impact on the prognosis of metabolic syndrome.

Exposure

Levels of dietary niacin intake based on 24-hour dietary recall.

Methods

Kaplan-Meier survival curves were used to compare survival status among quartiles of dietary niacin intake. Weighted Cox proportional hazards models and restricted cubic splines were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of all-cause and CVD mortality associated with the exposure.

Results

This cohort study included 8,744 participants, and during a median follow-up period of 106 months, 1,552 (17.7%) deaths were recorded, with 511 attributed to cardiovascular disease. Kaplan-Meier curves comparing quartiles of dietary niacin intake showed significant differences in both all-cause and cardiovascular mortality rates (log-rank p < 0.001). In the fully adjusted model, the highest quartile of dietary niacin intake was associated with HRs of 0.68 (95% CI: 0.54, 0.87, P = 0.002) for all-cause mortality and 0.63 (95% CI: 0.39, 0.78, P < 0.001) for cardiovascular mortality.

Conclusion

The results of this cohort study suggest that higher dietary niacin intake is associated with reduced cardiovascular and all-cause mortality risks in the metabolic syndrome population. Furthermore, there appears to be a dose-response relationship between dietary niacin intake and the risks of all-cause and cardiovascular mortality.

Project description:ObjectiveThe relationship between dietary niacin intake (DNI) and mortality rates among patients afflicted with chronic kidney disease (CKD) is a subject of debate. Utilizing data derived from the National Health and Nutrition Examination Survey (NHANES), this study adopts a retrospective cohort design with an aim to investigate the association in the American adult patients with CKD.MethodsA cohort study was conducted in the National Health and Nutrition Examination Survey (NHANES) between 2009 and 2018 that enrolled 6,191 CKD patients aged 20 years and above. We collected data on mortality through 31 December 2018. DNI was measured using a 24-h recall method. The relationship between DNI levels and mortality from all causes and cardiovascular causes was analyzed using weighted Cox proportional hazards models. The Kaplan-Meier (K-M) survival curve was plotted to illustrate these associations.ResultsFollowing a median monitoring period of 85 months, it was observed that 2,419 individuals (33.08%) succumbed to all causes, whereas cardiovascular-related deaths were recorded for 746 participants (10.45%). When controlling for confounders, an inverse relationship was established between DNI and mortality rates. Specifically, a marginal increase of 1 mg/day in DNI corresponded to a reduced Hazard Ratios (HRs) of 0.993 (0.987, 0.999; p = 0.027) for all-cause mortality and 0.980 (0.969, 0.991; p < 0.001) for cardiovascular mortality. A further stratified analysis by quartiles of DNI, with the lowest quartile serving as the reference, revealed that the highest quartile was associated with HRs of 0.820 (0.697, 0.966) for all-cause mortality and 0.663 (0.465, 0.944) for cardiovascular mortality, both displaying a significant trend (p < 0.001). However, a subdivision of CKD patients by age showed that the protective effects of higher DNI were only confined to individuals aged 60 years and above but not to those under 60 years of age.ConclusionA negative correlation between DNI and mortality due to all causes and cardiovascular issues among CKD patients aged 60 and above was revealed based on the datasets; however, this association was not observed in younger individuals under 60. Consequently, enhancing DNI might serve as a beneficial therapeutic strategy specifically for the older CKD demographic.

Project description:BackgroundChrono-nutrition emphasized the importance of the intake time; however, less is known about the impact of dietary vitamin intake time on health. This study aimed to examine our hypothesis about which vitamin intake time could influence the natural course of cardiovascular disease (CVD).MethodsA total of 27,455 adults enrolled in the National Health and Nutrition Examination Survey (NHANES) during 2003-2014 were recruited. The 12 dietary vitamin intakes in the morning, afternoon, and evening were categorized into tertiles or quartiles. Cox-proportional hazard regression models were developed to evaluate the association of vitamin intake time with CVD and all-cause mortalities.ResultsCompared with participants in the lowest quartile, participants in the highest quartile of dietary VB2 intake in the morning had significantly lowest mortality risk of CVD [hazard ratio (HR)VB2 = 0.75, 95% CI: 0.60-0.94, p = 0.017]; whereas, participants in the highest quartile of dietary-vitamin B6 (VB6), vitamin C (VC), vitamin E (VE), and folate-equivalent consumed in the evening showed the lowest risks of CVD (HRVB6 = 0.77, 95% CI: 0.60-0.99, p = 0.103; HRVC = 0.80, 95% CI: 0.65-0.98, p = 0.050; HRVE = 0.75, 95% CI: 0.56-0.99, p = 0.032; HRfolate-equivalent = 0.78, 95% CI: 0.63-0.97, p = 0.116) and all-cause mortalities (HRVB6 = 0.81, 95% CI: 0.71-0.93, p = 0.006; HRVC = 0.85, 95% CI: 0.76-0.95, p = 0.004; HRVE = 0.84, 95% CI: 0.72-0.97, p = 0.011; HRfolate-equivalent = 0.80, 95% CI: 0.71-0.90, p = 0.001). Moreover, equivalently replacing 10% intake of dietary VB6, VC, VE, and folate-equivalent in the morning with evening were associated with 4% (HRVB6 = 0.96, 95% CI: 0.92-0.99), 5% (HRVC = 0.95, 95% CI: 0.92-0.99), 4% (HRVE = 0.96, 95% CI: 0.91-0.99), and 5% (HRfolate-equivalent = 0.95, 95% CI: 0.92-0.99) lower risk of CVD mortality.ConclusionThis study found that the optimal intake time of dietary VB2 was in the morning, and the optimal intake times of dietary VB6, VC, VE, and folate-equivalent were in the evening.

Project description:Anthocyanins, as a type of polyphenolic compound, have been discovered to offer multiple health benefits to humans, including anti-aging and anti-inflammatory properties. This prospective cohort study aims to examine the relationship of dietary intake of anthocyanin with all-cause mortality and cardiovascular diseases mortality in the US. The aim of this research was to explore the possible correlation between anthocyanin consumption and the mortality rate from all causes as well as from cardiovascular disease. Based on the Public Access NHANES-linked National Death Index files up to December 31, 2019, we identified mortality status and heart disease-specific causes of death. A multivariate Cox regression analysis was employed to evaluate the effects of anthocyanin intake on mortality outcomes, generating hazard ratios and 95% confidence intervals, adjusting for various demographic characteristics, lifestyle factors, and comorbid conditions. Additionally, we utilized Kaplan-Meier survival curves, subgroup analyses. In different scenarios, dietary anthocyanin intake was assessed using restricted cubic spline models. A total of 11,959 participants completed the final cohort, averaging 47.12 years of age (SD ± 0.35). Following adjustments for multiple variables, an inverse relationship was identified between anthocyanin intake in the highest quartile and all causes mortality, yielding a hazard ratio (HR) of 0.68 (95% CI: 0.52-0.89). Similarly, elevated anthocyanin consumption was linked to a reduction in heart disease mortality, with HR of 0.61 (95% CI: 0.38-0.97). Additionally, dose-response curve revealed a consistent decrease in both all-cause and cardiovascular mortality with increasing anthocyanin intake. Further subgroup analyses revealed that elevated intake of anthocyanins was linked to decreased all-cause mortality in White individuals and males. Moreover, high anthocyanin intake was significantly correlated with reduced all-cause mortality irrespective of hypertension or hyperlipidemia status. Our research indicates that an appropriate dietary intake of anthocyanins is associated with a reduction in overall mortality rates. Furthermore, the findings reveal a substantial association between anthocyanin intake and decreased mortality from cardiovascular diseases, suggesting that anthocyanins may effectively lower the risk of cardiovascular-related deaths.
