Project description:ImportanceDifficulty maintaining balance is common among individuals aged 40 years or older and increases the risk of falls. However, little is known about the association of balance function with long-term mortality outcomes in adults.ObjectiveTo investigate the association of balance function with all-cause and cause-specific mortality among US adults.Design, setting, and participantsA prospective, population-based cohort study of a nationally representative sample of 5816 adults (weighted population, 92 260 641) from the US National Health and Nutrition Examination Survey was conducted from 1999 to 2004. Individuals aged 40 years or older who completed the modified Romberg Test of Standing Balance on Firm and Compliant Support Surfaces were included. Participants were linked to mortality data from the test date through December 31, 2015. Data analysis was conducted from February 1 to June 1, 2020.ExposuresThe modified Romberg Test of Standing Balance on Firm and Compliant Support Surfaces was used to measure balance function and define balance disorder according to sensory input.Main outcomes and measuresMortality associated with all causes, cardiovascular disease (CVD), and cancer.ResultsA total of 5816 adults (weighted mean [SE] age, 53.6 [0.2] years; 2897 [49.8%] women) were included in this cohort study. During up to 16.8 years of follow-up (median, 12.5 years; 68 919 person-years), 1530 deaths occurred, including 342 associated with CVD and 364 associated with cancer. Participants with balance disorder were at a higher risk of death from all causes, CVD, and cancer. After adjusting for sociodemographic characteristics, lifestyle factors, and chronic conditions, the hazard ratios (HRs) among participants with balance disorder compared with those without balance disorder were 1.44 (95% CI, 1.23-1.69) for all-cause mortality, 1.65 (95% CI, 1.17-2.31) for CVD mortality, and 1.37 (95% CI, 1.03-1.83) for cancer mortality. Furthermore, vestibular balance disorder was associated with increased mortality from all causes (HR, 1.31; 95% CI, 1.08-1.58), CVD (HR, 1.59; 95% CI, 1.12-2.27), and cancer (HR, 1.39; 95% CI, 1.04-1.86).Conclusions and relevanceIn this nationally representative sample of US adults, balance disorder was associated with an increased risk of all-cause, CVD, and cancer mortality. Further studies are needed to confirm these findings and evaluate whether the observed associations represent a causal biological phenomenon and, if so, whether the effect is modifiable with a multicomponent exercise program.

Project description:BackgroundSedentary behaviors predominate modern life, yet we do not fully understand the adverse effects of these behaviors on mortality after considering the benefits of moderate-vigorous physical activity (MVPA).ObjectiveWe tested the hypotheses that higher amounts of overall sitting time and television viewing are positively associated with mortality and described the independent and combined effects of these sedentary behaviors and MVPA on mortality.DesignIn the NIH-AARP Diet and Health Study, we examined 240,819 adults (aged 50-71 y) who did not report any cancer, cardiovascular disease, or respiratory disease at baseline. Mortality was ascertained over 8.5 y.ResultsSedentary behaviors were positively associated with mortality after adjustment for age, sex, education, smoking, diet, race, and MVPA. Participants who reported the most television viewing (≥7 h compared with <1 h/d) were at greater risk of all-cause (HR: 1.61; 95% CI: 1.47, 1.76), cardiovascular (HR: 1.85; 95% CI: 1.56, 2.20), and cancer (HR: 1.22; 95% CI: 1.06, 1.40) mortality after adjustment for MVPA. Overall sitting was associated with all-cause mortality. Even among adults reporting high levels of MVPA (>7 h/wk), high amounts of television viewing (≥7 h/d) remained associated with increased risk of all-cause (HR: 1.47; 95% CI: 1.20, 1.79) and cardiovascular (HR: 2.00; 95% CI: 1.33, 3.00) mortality compared with those reporting the least television viewing (<1 h/d).ConclusionsTime spent in sedentary behaviors was positively associated with mortality, and participation in high levels of MVPA did not fully mitigate health risks associated with prolonged time watching television. Adults should be encouraged to reduce time spent in sedentary behaviors, when possible, and to participate in MVPA at recommended levels. The NIH-AARP Diet and Health Study was registered at clinicaltrials.gov as NCT00340015.

Project description:IntroductionThe survival benefit of residual kidney function (RKF) in patients on hemodialysis is presumably due to enhanced fluid management and solute clearance. However, data are lacking on the association of renal urea clearance (CLurea) with specific causes of death.MethodsWe conducted a longitudinal cohort study of 39,623 adults initiating thrice-weekly in-center hemodialysis from 2007 to 2011 and had data on renal CLurea and urine volume. Multivariable cause-specific proportional hazards model was used to examine the associations between baseline RKF and cause-specific mortality, including sudden cardiac death (SCD), non-SCD cardiovascular death (CVD), and non-CVD. Restricted cubic splines were fitted for change in RKF over 6 months after initiating hemodialysis.ResultsAmong 39,623 patients with data on baseline renal CLurea and urine volume, there was a significant trend toward a higher mortality risk across lower RKF levels, irrespective of cause of death in a case-mix adjustment model (Ptrend < 0.05). Adjustment for ultrafiltration rate (UFR) slightly attenuated the association between low renal CLurea and high cause-specific mortality, whereas adjustment for highest potassium did not have substantial effect. Among 12,169 patients with data on change in RKF, a 6-month decline in renal CLurea showed graded associations with SCD, non-SCD CVD, and non-CVD risk, whereas the graded associations between faster 6-month decline in urine output and higher death risk were clear only for SCD and non-CVD.ConclusionLower RKF and loss of RKF were associated with higher cause-specific mortality among patients initiating thrice-weekly in-center hemodialysis.

Project description:ImportanceThe joint association of antihypertensive medication use and healthy lifestyle with mortality among individuals with hypertension is unclear.ObjectiveTo examine the association of lifestyle factors combined with antihypertensive medication use, as well as changes in lifestyle, with all-cause and cause-specific mortality among individuals with hypertension.Design, setting, and participantsThis cohort study used data from the Dongfeng-Tongji cohort, a long-term, prospective cohort including employees at a manufacturer in China, with baseline from 2008 to 2010. Participants with hypertension were followed up for a median (IQR) of 7.3 (5.7-10.3) years, ending in 2018. Data were analyzed from February to April 2021.ExposuresLifestyle factors, including body mass index, smoking status, diet, physical activity, and sleep duration, were coded on a 3-point scale (range, 0-2, with higher score indicating a healthier lifestyle). Lifestyle was evaluated according to the total score of all 5 factors, and categorized into 3 groups: unfavorable (scores 0-4), intermediate (scores 5-7), and favorable (scores 8-10). Antihypertensive medication use was defined as use within the last 2 weeks.Main outcomes and measuresAll-cause, cardiovascular, and cancer mortality were identified by linking the cohort database with the health care system through December 31, 2018.ResultsA total of 14 392 participants (mean [SD] age, 65.6 [7.4] years; 7277 [50.6%] men and 7115 [49.4%] women) with hypertension were included, and 2015 deaths were documented, including 761 cardiovascular deaths and 525 cancer deaths. Compared with individuals not using antihypertensive medication and with a lifestyle score of 0 to 4, the combination of using antihypertensive medication and having a lifestyle score of 8 to 10 was associated with the lowest risk of all-cause mortality (hazard ratio [HR], 0.32; 95% CI, 0.25-0.42), cardiovascular mortality (HR, 0.33; 95% CI, 0.21-0.53), and cancer mortality (HR, 0.30; 95% CI, 0.19-0.47). In addition, improvement in lifestyle score after hypertension diagnosis was associated with lower risk of all-cause mortality (HR, 0.52; 95% CI, 0.36-0.76) and cardiovascular mortality (HR, 0.53; 95% CI, 0.30-0.94).Conclusions and relevanceThese findings suggest that adherence to healthy lifestyle and antihypertensive medication treatment were associated with lower risk of mortality among adults with hypertension. These findings further support that, in addition to antihypertensive medication use, adopting a healthy lifestyle is associated with benefits in the prevention of premature death among individuals with hypertension.

Project description:ImportanceThe benefits of smoking cessation are well known, but former smokers have a higher health risk than never smokers. The impact of former smokers' engaging in other aspects of a healthy lifestyle is unclear.ObjectiveTo assess the association between adherence to evidence-based lifestyle recommendations and mortality among former smokers.Design, setting, and participantsThis prospective cohort study included 159 937 participants in the National Institutes of Health-AARP Diet and Health Study of older US adults who completed the baseline and risk factor questionnaires and self-identified as former smokers. Baseline questionnaires were mailed from 1995 to 1996. Data analysis was performed from November 2020 to November 2021.ExposuresAdherence to evidence-based lifestyle recommendations was scored for body weight (scores, 0-2), diet (scores, 0-3), physical activity (scores, 0-2), and alcohol intake (scores, 0-1) recommendations, with higher scores indicating better adherence. Individual lifestyle adherence scores were summed to make a total adherence score (scores, 0-8).Main outcomes and measuresThe primary outcomes were all-cause and cause-specific mortality through December 31, 2019, with a mean (SD) follow-up of 18.9 (6.3) years. Hazard ratios (HRs) and 95% CIs were computed using a multivariable Cox proportional hazards regression model.ResultsAmong 159 937 former smokers (mean [SD] age, 62.6 [5.2] years; 106 912 [66.9%] male; 149 742 [93.6%] White), 86 127 deaths occurred. A higher total adherence score was associated with lower all-cause mortality (HR per unit increase, 0.95; 95% CI, 0.94-0.95). Compared with the lowest total adherence score category (scores, 0-2), the HRs for all-cause mortality were 0.88 (95% CI, 0.86-0.90) for scores of 3 to 4, 0.80 (95% CI, 0.79-0.82) for scores of 5 to 6, and 0.73 (95% CI, 0.71-0.75) for scores of 7 to 8. Associations were observed regardless of health status, comorbid conditions, the number of cigarettes participants used to smoke per day, years since cessation, and age at smoking initiation. When examined individually, the HRs for highest vs lowest adherence score were 0.86 (95% CI, 0.84-0.88) for body weight, 0.91 (95% CI, 0.90-0.93) for diet, 0.83 (95% CI, 0.81-0.85) for physical activity, and 0.96 (95% CI, 0.94-0.97) for alcohol intake recommendations. Participants with a higher total adherence score also had a lower risk of mortality from cancer, cardiovascular disease, and respiratory disease.Conclusions and relevanceIn a large US cohort of former smokers, better adherence to healthy lifestyle recommendations was associated with lower mortality risk. These results provide evidence that former smokers may benefit from adhering to lifestyle recommendations, as do other groups.

Project description:ImportanceElevated blood pressure is a major cause of premature death, but there is little direct evidence demonstrating this association in studies of Hispanic populations.ObjectiveTo assess the association between blood pressure and cause-specific mortality in a large cohort of Mexican adults with a high prevalence of uncontrolled diabetes.Design, setting, and participantsA total of 159 755 adults aged 35 years or older from 2 districts in Mexico City were recruited to this cohort study between April 1998 and September 2004 and followed up until January 2018. The present analyses focused on 133 613 participants who were aged 35 to 74 years and had no history of chronic disease besides diabetes.ExposureBlood pressure.Main outcomes and measuresCox regression, adjusted for confounders, yielded mortality rate ratios (RRs) for deaths of participants occurring between ages 35 and 74 years.ResultsOf the 133 613 participants (43 263 [32.4%] men; mean [SD] age, 50 [11] years), 16 911 (12.7%) had self-reported previously diagnosed diabetes (including 8435 [6.3%] with uncontrolled diabetes, defined as hemoglobin A1c ≥9%) and 6548 (4.9%) had undiagnosed diabetes. Systolic blood pressure (SBP) was associated with vascular mortality between ages 35 to 74 years, with each 20 mm Hg lower usual SBP associated with 35% lower vascular mortality (RR, 0.65; 95% CI, 0.61-0.68), including 48% lower stroke mortality (RR, 0.52; 95% CI, 0.47-0.59) and 32% lower ischemic heart disease mortality (RR, 0.68; 95% CI, 0.63-0.74). These RRs were broadly similar in those with and without diabetes. Compared with those without diabetes and SBP less than 135 mm Hg at recruitment, the vascular mortality RR was 2.8 (95% CI, 2.4-3.3) for those without diabetes and SBP of 155 mm Hg or greater, 4.7 (95% CI, 4.1-5.4) for those with uncontrolled diabetes and SBP less than 135 mm Hg, and 8.9 (95% CI, 7.2-11.1) for those with uncontrolled diabetes and SBP of 155 mm Hg or greater. Lower SBP was also associated with decreased kidney-related mortality (RR per 20 mm Hg lower usual SBP, 0.69; 95% CI, 0.64-0.74), decreased mortality from infection (RR, 0.81; 95% CI, 0.71-0.91), and decreased mortality from hepatobiliary disease (RR, 0.87; 95% CI, 0.78-0.98), but not decreased neoplastic or respiratory mortality. SBP was more informative for vascular mortality than other blood pressure measures (eg, compared with SBP, diastolic blood pressure was only two-thirds as informative).Conclusions and relevanceBlood pressure was most strongly associated with vascular and kidney-related mortality in this Mexican population, with particularly high absolute excess mortality rates among individuals with diabetes. The findings reinforce the need for more widespread use of blood pressure-lowering medication in Mexico, particularly among those with diabetes.

Project description:BackgroundRetinal microvascular abnormalities (RMA) reflect cumulative microvascular damage from systemic diseases and aging. However, little is known about the association between RMA and long-term survival outcomes. This study aimed to examine the relationships between RMA and the risk of all-cause and specific-cause mortality among U.S. adults.MethodsIndividuals aged ≥ 40 years were included from the U.S. National Health and Nutrition Examination Survey, 2005-2008. RMA and its subtypes, including retinopathy, arteriovenous nicking (AVN), focal arteriolar narrowing (FAN) and Hollenhorst plaque (HP), were manually graded from retinal photographs. Associations between RMA and the risk of all-cause and cause-specific mortality were examined with Cox regression analysis.ResultsThis cohort study of 5775 adults included 2881 women (weighted proportion, 52.6%) and 2894 men (weighted, 47.4%), with a weighted mean (SE) age of 56.6 (0.4) years. RMA were present in 1251 participants (weighted, 17.9%), of whom 710 (weighted, 9.8%) had retinopathy, 635 (weighted, 9.3%) had AVN, 64 (weighted, 1.0%) had FAN, and 21 (weighted, 0.3%) had HP. During a median of 12.2 years (range, 0.1-15.0 years) of follow-up, 1488 deaths occurred, including 452 associated with cardiovascular disease (CVD), 341 associated with cancer, and 695 associated with other causes. After adjusting confounding factors, the presence of any RMA and retinopathy at baseline was associated with higher risk of all-cause mortality (HR, 1.26; 95%CI, 1.07-1.47; HR, 1.36; 95%CI, 1.09-1.71, respectively), CVD mortality (HR, 1.36; 95%CI, 1.06-1.73; HR, 1.53; 95%CI, 1.04-2.26, respectively) and other-cause mortality (HR, 1.33; 95%CI, 1.06-1.67; HR, 1.55; 95%CI, 1.20-2.01, respectively). Additionally, FAN was significantly associated with an increased risk of other-cause mortality (HR, 2.06; 95%CI, 1.16-3.65). Although AVN was not associated with mortality in the whole population, it was significantly related to higher risks of all-cause and CVD death in those with obesity (HR, 1.68; 95%CI, 1.12-2.52; HR, 1.96; 95%CI, 1.23-3.13, respectively).ConclusionsThis study revealed that the presence of RMA is independently associated with greater risks of all-cause, CVD and other-cause mortality in adults aged 40 years or older.

Project description:BackgroundThe link of low estimated glomerular filtration rate (eGFR) and high proteinuria to cardiovascular disease (CVD) mortality is well known. However, its link to mortality due to other causes is less clear.MethodsWe studied 367,932 adults (20-93 years old) in the Korean Heart Study (baseline between 1996-2004 and follow-up until 2011) and assessed the associations of creatinine-based eGFR and dipstick proteinuria with mortality due to CVD (1,608 cases), cancer (4,035 cases), and other (non-CVD/non-cancer) causes (3,152 cases) after adjusting for potential confounders.ResultsAlthough cancer was overall the most common cause of mortality, in participants with chronic kidney disease (CKD), non-CVD/non-cancer mortality accounted for approximately half of cause of death (47.0%for eGFR <60 ml/min/1.73 m2 and 54.3% for proteinuria ≥1+). Lower eGFR (<60 vs. ≥60 ml/min/1.73 m2) was significantly associated with mortality due to CVD (adjusted hazard ratio 1.49 [95% CI, 1.24-1.78]) and non-CVD/non-cancer causes (1.78 [1.54-2.05]). The risk of cancer mortality only reached significance at eGFR <45 ml/min/1.73 m2 when eGFR 45-59 ml/min/1.73 m2 was set as a reference (1.62 [1.10-2.39]). High proteinuria (dipstick ≥1+ vs. negative/trace) was consistently associated with mortality due to CVD (1.93 [1.66-2.25]), cancer (1.49 [1.32-1.68]), and other causes (2.19 [1.96-2.45]). Examining finer mortality causes, low eGFR and high proteinuria were commonly associated with mortality due to coronary heart disease, any infectious disease, diabetes, and renal failure. In addition, proteinuria was also related to death from stroke, cancers of stomach, liver, pancreas, and lung, myeloma, pneumonia, and viral hepatitis.ConclusionLow eGFR was associated with CVD and non-CVD/non-cancer mortality, whereas higher proteinuria was consistently related to mortality due to CVD, cancer, and other causes. These findings suggest the need for multidisciplinary prevention and management strategies in individuals with CKD, particularly when proteinuria is present.

Project description:Background and aimsThe performance of high sensitivity troponin T (hs-cTnT), hs-cTnI, and N-terminal pro-hormone brain natriuretic peptide (NT-proBNP) in patients with chronic kidney disease (CKD) is poorly understood.MethodsWe included adults with CKD (eGFR<60 ml/min/1.73m2) in the 1999-2004 NHANES. We calculated the 99th percentile of hs-cTnT, hs-cTnI (Abbott, Ortho, and Siemens assays), and NT-proBNP, measured the association between eGFR and cardiac biomarker concentration, and used Cox regression models to assess the relationship between cardiac biomarkers and CVD mortality.ResultsAcross 1,068 adults with CKD, the mean [SD] age was 71.9[12.7] years and 61.2% were female; 78.8% had elevated NT-proBNP and 42.6% had elevated hs-cTnT based on traditional clinical reference limits. The 99th percentile of hs-cTnT was 122 ng/L (95% confidence interval (CI) 101-143), hs-cTnIAbbott was 69 ng/L (95% CI 38-99), and NT-proBNP was 8952 pg/mL (95% CI 7506-10,399). A 10 ml/min decrease in eGFR was associated with greater increases in hs-cTnT and NT-proBNP than hs-cTnI (hs-cTnT: 27.5% increase (β=27.5, 95% CI 28.2-43.3)), NT-proBNP 46.0% increase (β=46.0, 95% CI 36.0-56.8), hs-cTnISiemens 17.9% (β=17.9, 95% CI 9.7-26.7). Each doubling of hs-cTnT, hs-cTnI, and NT-proBNP were associated with CVD mortality (hs-cTnT HR 1.62 [95% CI 1.32-1.98], p<0.0001; hs-cTnISiemens HR 1.40 [95% CI 1.26-1.55], p<0.0001; NT-proBNP HR 1.29 [95% CI 1.19-1.41], p<0.0001).Conclusions and relevanceCommunity dwelling adults with CKD have elevated concentrations of cardiac biomarkers, above established reference ranges. Of the troponin assays, hs-cTnI concentration appears to be most stable across eGFR categories and is associated with CVD mortality.

Project description:Information on common causes of death in people with CKD is limited. We hypothesized that, as eGFR declines, cardiovascular mortality and mortality from infection account for increasing proportions of deaths. We calculated eGFR using the CKD Epidemiology Collaboration equation for residents of Alberta, Canada who died between 2002 and 2009. We used multinomial logistic regression to estimate unadjusted and age- and sex-adjusted differences in the proportions of deaths from each cause according to the severity of CKD. Cause of death was classified as cardiovascular, infection, cancer, other, or not reported using International Classification of Diseases codes. Among 81,064 deaths, the most common cause was cancer (31.9%) followed by cardiovascular disease (30.2%). The most common cause of death for those with eGFR≥60 ml/min per 1.73 m(2) and no proteinuria was cancer (38.1%); the most common cause of death for those with eGFR<60 ml/min per 1.73 m(2) was cardiovascular disease. The unadjusted proportion of patients who died from cardiovascular disease increased as eGFR decreased (20.7%, 36.8%, 41.2%, and 43.7% of patients with eGFR≥60 [with proteinuria], 45-59.9, 30-44.9, and 15-29.9 ml/min per 1.73 m(2), respectively). The proportions of deaths from heart failure and valvular disease specifically increased with declining eGFR along with the proportions of deaths from infectious and other causes, whereas the proportion of deaths from cancer decreased. In conclusion, we found an inverse association between eGFR and specific causes of death, including specific types of cardiovascular disease, infection, and other causes, in this cohort.
