Relationship between the exposure to cumulative cardiovascular health behaviors and factors and chronic kidney disease-The Kailuan study

Association of Life's Essential 8 with risk of incident cardiovascular disease and mortality among adults with chronic kidney disease

Background

The American Heart Association recently released an updated algorithm for evaluating cardiovascular health (CVH), Life's Essential 8 (LE8). However, few studies have examined the association of LE8 with risk of cardiovascular disease (CVD) and mortality among individuals with chronic kidney disease (CKD). We investigated whether LE8 was associated with subsequent risk of CVD and mortality in the Chinese population of adults with CKD.

Methods

This prospective study included 18,716 adults (55.4 ± 14.0 years, 77.9 % men) with CKD free of CVD at baseline from the Kailuan study. A LE8 score (range 0-100 points) was constructed based on diet, physical activity, smoking, sleep duration, body mass index, blood lipids, blood glucose, and blood pressure. Incident CVD and mortality were identified by electronic health records and registers. Multivariable Cox regression models were used to compute hazard ratios (HRs) and 95 % confidence intervals (CIs).

Results

During a median follow-up of 14.0 and 14.4 years, 2117 cases of CVD and 4190 deaths were documented. After adjusting for potential confounders, comparing the high LE8 score (80-100 points) to the low LE8 score (<50 points), the multivariable HRs (95 % CIs) were 0.28 (0.20, 0.40) for CVD, 0.14 (0.06, 0.34) for myocardial infarction, 0.35 (0.25, 0.50) for total stroke, and 0.68 (0.56, 0.83) for all-cause mortality, respectively.

Conclusions

Among patients with CKD, greater adherence to CVH, as defined by LE8, was significantly associated with a lower risk of CVD and all-cause mortality.

Association between uric acid to high-density lipoprotein cholesterol ratio and chronic kidney disease among Chinese middle-aged and older adults with abnormal glucose metabolism: a nationwide cohort study

BACKGROUND

Previous research has demonstrated a correlation between uric acid to high-density lipoprotein cholesterol ratio (UHR) and chronic kidney disease (CKD), yet the evidence remains unclear in individuals with abnormal glucose metabolism. The objective of this research was to investigate the correlation between UHR and the occurrence of CKD, as well as the rapid kidney function decline among individuals aged over 45 years with abnormal glucose metabolism, using data from the China Health and Retirement Longitudinal Study (CHARLS).

METHODS

This study employed K-means clustering to categorize individuals based on UHR control levels into four classes. Subsequently, multivariate logistic regression analyses were utilized to explore the relationships between UHR and the occurrence of CKD as well as rapid kidney function decline. To examine the potential nonlinear relationship, restricted cubic spline (RCS) analyses were employed. Subgroup analyses and various sensitivity analyses were applied to validate the reliability of the results.

RESULTS

This study encompassed 3902 participants, all of whom had prediabetes or diabetes. In the fully adjusted logistic regression model assessing the risk of CKD development, the odds ratios (ORs) for Class 2, Class 3, and Class 4, versus Class 1, were 1.08 (0.71 to 1.67), 1.71 (1.06 to 2.77), and 2.13 (1.02 to 4.35), respectively. For every 1 standard deviation (SD) increase in cumulative UHR exposure, there was a 32% elevation in the risk of CKD incidence (OR: 1.32, 95% CI 1.12 to 1.56). RCS curves suggested a linear association between cumulative UHR (CumUHR) and CKD occurrence, but a nonlinear association with rapid renal function progression. Subgroup analysis indicated an interaction between age and UHR on the development of CKD. The application of multiple sensitivity analyses yielded consistent outcomes, suggesting the robustness of the findings.

CONCLUSION

In individuals with abnormal glucose metabolism, suboptimal control of UHR signifies an elevated risk of rapid kidney function decline and the incidence of CKD in the future. Therefore, close monitoring of long-term variations in UHR can facilitate early identification of the risk for CKD development.

Association of life's essential 8 with prevalence and all-cause mortality of chronic kidney disease among US adults: Results from the National Health and Nutrition Examination Survey (2015-2018)

Background and Objectives

The association between chronic kidney disease (CKD) and cardiovascular disease has been previously evaluated. This study aimed to evaluate the association between the American Heart Association's Life's Essential 8 (LE8) and the prevalence and all-cause mortality of CKD in a nationally representative population of adults in the US.

Methods

This retrospective analysis included participants from the National Health and Nutrition Examination Survey spanning 2015-2018. We used multivariable survey logistic regression model to calculate the adjusted odds ratios (AORs) of the LE8 score for the prevalence of CKD. Survey-weighted Cox proportional hazards models were used to calculate the adjusted hazards ratios (AHRs) of the LE8 score for the risk of all-cause mortality among participants with CKD.

Results

Of the 8907 included participants, 789 had stage 3 to 5 CKD, and 8118 were in the non-CKD group. The adjusted prevalence rate of CKD was 10.7% in the low LE8 score group, and lower in the moderate (7.9%) and high (7.7%) LE8 score groups. Compared with low LE8 scores, moderate LE8 score (adjusted odds ratio [AOR] 0.628, 95% confidence interval [CI]: 0.463 to 0.853, P = 0.004) and high LE8 scores (AOR 0.328, 95% CI: 0.142 to 0.759, P = 0.011) were associated with lower prevalence rates of CKD. A similar association was found for health factors scores. Additionally, an increase in the LE8 score was associated with a lower risk of all-cause mortality (adjusted hazard ratio [AHR] 0.702, 95% CI: 0.594 to 0.829, P < 0.001).

Conclusion

The results of this study suggest the association of higher LE8 and its subscale scores with a lower prevalence and all-cause mortality of CKD.

Association between the trajectory of ideal cardiovascular health metrics and incident chronic kidney disease among 27,635 older adults in northern China-a prospective cohort study

BACKGROUND

There is a lack of relevant studies evaluating the long-term impact of cardiovascular health factor (CVH) metrics on chronic kidney disease (CKD).

OBJECTIVE

This study investigates the long-term change in CVH metrics in older people and explores the relationship between CVH metrics trajectory and CKD.

METHODS

In total, 27,635 older people aged over 60 from the community-based Tianjin Chronic Kidney Disease Cohort study were enrolled. The participants completed five annual physical examinations between January 01, 2014, and December 31, 2018, and a subsequent follow-up between January 01, 2019, and December 31, 2021. CVH metrics trajectories were established by the group-based trajectory model to predict CKD risk. The relationships between baseline CVH, CVH change (ΔCVH), and CKD risk were also explored by logistic regression and restricted cubic spline regression model. In addition, likelihood ratio tests were used to compare the goodness of fit of the different models.

RESULTS

Six distinct CVH metrics trajectories were identified among the participants: low-stable (11.19%), low-medium-stable (30.58%), medium-stable (30.54%), medium-high-decreased (5.46%), medium-high-stable (18.93%), and high-stable (3.25%). After adjustment for potential confounders, higher CVH metrics trajectory was associated with decreased risk of CKD (P for trend < 0.001). Comparing the high-stable with the low-stable group, the risk of CKD decreased by 46%. All sensitivity analyses, including adjusting for baseline CVH and removing each CVH component from the total CVH, produced consistent results. Furthermore, the likelihood ratio test revealed that the model established by the CVH trajectory fit better than the baseline CVH and Δ CVH.

CONCLUSION

The higher CVH metrics trajectory and improvement of CVH metrics were associated with decreased risk of CKD. This study emphasized the importance of improving CVH to achieve primary prevention of CKD in older people.

Association of ideal cardiovascular health metrics with incident low estimated glomerular filtration rate: More than a decade follow-up in the Tehran Lipid and Glucose Study (TLGS)

AIMS

To evaluate the association between ideal cardiovascular health metrics (ICVHM) and incident low estimated glomerular filtration rate (eGFR) among the Iranian population.

METHODS

The study population included 6927 Iranian adults aged 20-65 years (2942 male) without prevalent low eGFR [i.e., eGFR < 60 ml/min/1.73 m2] and free of cardiovascular disease. The ICVHM was defined according to the 2010 American Heart Association. The multivariable Cox proportional hazards regression analysis was used to calculate the hazard ratios (HRs) of ICVHM both as continuous and categorical variables.

RESULTS

Over the median of 12.1 years of follow-up, we found 1259 incident cases of low eGFR among the study population. In this population, ideal and intermediate categories of body mass index (BMI) and blood pressure (BP) and only the ideal category of fasting plasma glucose (FPG) significantly decreased the risk of developing low eGFR; the corresponding HRs and (95% confidence intervals) were (0.87, 0.77-0.99), (0.84, 0.76-0.99), (0.79, 0.68-0.93), (0.70, 0.60-0.83) and (0.76, 0.64-0.91). Also, one additional ICVHM was associated with a reduced risk of low eGFR for the global (0.92, 0.88-0.97) and biological cardiovascular health (0.88, 0.82-0.93) in these participants. A sensitivity analysis using the interval-censoring approach demonstrated that our method is robust, and results remained essentially unchanged. In a subgroup population with dietary data (n = 2285), we did not find the beneficial impact of having intermediate/ideal categories of nutrition status compared to its poor one on incident low eGFR.

CONCLUSION

We found a strong inverse association between having higher global ICVHM with incident low eGFR among the non-elderly Iranian population; the issue is mainly attributable to normal BP, BMI, and FPG levels.

Age-dependent interaction between Life's Essential 8 and chronic kidney disease: A national cross-sectional analysis

OBJECTIVE

Chronic kidney disease (CKD), an age-related condition, is closely associated with cardiovascular disease. We aimed to examine the age-dependent interaction between Life's Essential 8 (LE8), the updated measurement of cardiovascular health (CVH), and CKD in the United States.

METHODS

The cross-sectional study involved 25,529 participants from National Health and Nutrition Examination Survey in 2007-2018. Multivariate logistic regressions were used to estimate the age-dependent interaction between LE8 and CKD, and restricted cubic spline regressions were used to analyze the dose-response relationships between LE8 and CKD among adults and all age subgroups.

RESULTS

Overall, 2934 (9.3%), 17,278 (66.2%), and 5317 (24.5%) participants had low, moderate, and high CVH, separately. After adjusting for the potential covariates, LE8 was negatively associated with CKD [odds ratio (OR) for per 1 standard deviation (SD) increase and 95%CI, 0.71 (0.67, 0.75)], with a nonlinear dose-response relationship (P for nonlinearity = 0.001). The inversed association was stronger among participants aged 65 and older (0.65 (0.59, 0.71)) compared to youngers [20-39 years, 0.63 (0.59, 0.58), 40-64 years, 0.63 (0.59, 0.58)] (P for interaction = 0.002).

CONCLUSIONS

CVH, as measured by the LE8 score, was negatively associated with the presence of CKD in non-linear fashions, more pronounced in participants aged 65 and older compared to younger age groups.

Better Life's Essential 8 Is Associated With Lower Risk of Diabetic Kidney Disease: A Community-Based Study

Background Diabetic kidney disease (DKD) is a common diabetic complication and increases the complexity of diabetes management. No prospective study has focused on the association between DKD and Life's Essential 8 (LE8). Our study aims to examine the association between LE8 and DKD risk. Methods and Results A total of 7605 participants, aged 54.32±9.77 years, and 4688 participants, aged 56.11±10.38 years, were included in the longitudinal and trajectory analyses, respectively, from 2006 to 2020. The DKD was confirmed using data collected during each follow-up. LE8 was based on 4 health behaviors and 4 health factors. The range of each metric was 0 to 100, and the overall LE8 score was calculated as the unweighted average of all 8 component metric scores. The trajectories of LE8 during 2006 to 2010 were classified using latent mixture models. Cox models and restricted cubic splines were applied. After a median follow-up of 12.41 and 6.71 years in longitudinal and trajectory analyses, respectively, the DKD incidence decreased, with the LE8 level increasing (P-trend<0.05), and the linearity assumption for this relationship (P-nonlinear=0.685) had been satisfied. Adjusted hazard ratios (HRs) for the highest tertile were 0.77 (95% CI, 0.69-0.87) and 0.70 (95% CI, 0.62-0.78) in baseline and time-updated LE8 scores, respectively, compared with the lowest tertile. Adjusted HR was 0.53 (95% CI, 0.41-0.69) for the stable-high pattern compared with the stable-low pattern. Conclusions Although LE8 is an indicator of cardiovascular health, the beneficial impact of a high LE8 score is also evident in the protection of renal health among patients with diabetes.
