Introduction: Studies have demonstrated that higher cardiorespiratory fitness (CRF) is associated with a lower risk of cardiovascular disease (CVD) and mortality. However, exercise CRF test is not routinely performed in clinical settings because it requires specialized equipment and trained personnel. Therefore, non-exercise estimated CRF (eCRF) using easily accessible health indicators in clinical practice may be a time- and cost-effective alternative for evaluating fitness. Hypothesis: We hypothesized that higher eCRF in midlife will be associated with a lower risk of CVD and all-cause mortality in later life. Methods: We evaluated 2,501 Framingham Offspring cohort participants (mean age 65 yrs., 52% women). We used a longitudinal non-exercise algorithm that includes age, sex, body mass index, waist circumference, resting heart rate, physical activity, and smoking status. We then used SAS PROC TRAJ to identify sex-specific latent patterns of eCRF (low, moderate, and high eCRF categories) between exam 2 and 8 (1979-2008). Multivariable Cox proportional hazards regression models were used to relate the long-term trajectories of eCRF to incident CVD and all-cause mortality on follow-up. Results: We identified three distinct trajectories of eCRF (Low [n=268, 10.7%] vs. moderate [n=1,273, 50.9%] vs. high [n=960, 38.4%]). Overall, 265 participants developed CVD and 429 died during 10 years of median follow-up. Participants in the “high eCRF” group were at lower risk of CVD and all-cause mortality compared to those in the “low eCRF” group, after adjustment for potential confounders ( Table ). Conclusions: Our findings suggest that lower eCRF during midlife may be a marker of risk of CVD and mortality in older adulthood.

Introduction: Non-exercise estimated cardiorespiratory fitness (eCRF) algorithms have shown similar accuracy to CRF estimated from submaximal and maximal exercise tests in healthy adults. Using easily accessible health indicators, eCRF measurement does not involve in-person exercise testing, trained personnel, or specialized equipment for measuring CRF. Thus, eCRF may be a cost-effective alternative for heart disease risk stratification. The relation between eCRF and Heart failure (HF) remains unclear. Hypothesis: We hypothesized that higher midlife eCRF is associated with a lower risk of incident HF in later life. Methods: We evaluated 2,226 Framingham Offspring cohort participants attending examination cycles 2 and 7 (mean age of 42- 61years; 53% women). We used a validated longitudinal non-exercise algorithm for eCRF including age, sex, body mass index, waist circumference, resting heart rate, physical activity, and smoking status. Midlife eCRF was defined as a sex-specific standardized average of eCRF (z-score of the average eCRF with mean=0 and a standard deviation [SD]=1) between cycles 2 and 7. The sex-specific midlife eCRF were then categorized into three groups based on tertiles and was also analyzed as a continuous variable (per 1 SD increment). We used multivariable Cox proportional hazards regression models for pooled sexes to relate the midlife eCRF to incident HF after examination cycle 7. Results: Overall, 189 participants developed HF during a median of 17 years of follow-up. Participants in either moderate or high eCRF group experienced a 52% lower risk of HF compared to those in the low eCRF group, after adjustment for potential confounders. Additionally, each SD increment in midlife eCRF was associated with a 40% lower risk of HF in later life. The associations remained significant after excluding participants on antihypertensive treatment (Table). Conclusions: Lower eCRF during midlife may be a marker of higher HF risk in later life.

Abstract Whether genetic and familial factors influence the association between cardiorespiratory fitness (CRF) and cardiovascular disease (CVD) is unknown. Two cohorts were formed based on data from 1,212,295 men aged 18 years who were conscripted for military service in Sweden during 1972–1996. The first comprised 4,260 twin pairs in which the twins in each pair had different CRF (≥1 watt). The second comprised 90,331 nonsibling pairs with different CRF and matched on birth year and year of conscription. Incident CVD and all-cause mortality were identified using national registers. During follow-up (median 32 years), there was no difference in CVD and mortality between fitter twins and less fit twins (246 vs. 251 events; hazard ratio (HR) = 1.00, 95% confidence interval (CI): 0.83, 1.20). The risks were similar in twin pairs with ≥60-watt difference in CRF (HR = 0.96, 95% CI: 0.57, 1.64). In contrast, in the nonsibling cohort, fitter men had a lower risk of the outcomes than less fit men (4,444 vs. 5,298 events; HR = 0.83, 95% CI: 0.79, 0.86). The association was stronger in pairs with ≥60-watt difference in CRF (HR = 0.65, 95% CI: 0.59, 0.71). These findings indicate that genetic and familial factors influence the association of CRF with CVD and mortality.

Aims: To investigate whether or not the association between baseline cardiovascular health (CVH) and incident cardiovascular disease (CVD) differs by event phenotypes and to address the mediating effect of inflammatory and haemostatic blood biomarkers. Methods: The association of ideal CVH with outcomes was computed in 9312 middle-aged men from Northern Ireland and France (whole cohort) in multivariable Cox proportional hazards regression analysis. The mediating effect of baseline blood biomarkers was evaluated in a case control study nested within the cohort after 10 years of follow-up. Results: After a median follow-up of 10 years, 614 first CHD events and 117 first stroke events were adjudicated. Compared to those with poor CVH, those with an ideal CVH profile at baseline had a 72% lower risk of CHD (HR=0.28; 95% CI: 0.17; 0.46) and a 76% lower risk of stroke (HR=0.24; 95% CI: 0.06; 0.98). No heterogeneity was detected across main CHD and main stroke phenotypes. While significantly lower mean concentrations of hs-CRP, IL-6 (inflammatory markers), and fibrinogen, von Willbrandt factor (haemostatic factors) were noted in the controls with higher CVH status, the association of CVH with incident CHD was not attenuated upon adjustment for these biomarkers. Conclusion: these results support the universal promotion of ideal CVH for CVD in general and suggest that the lower risk of CHD associated with ideal CVH is independent from inflammatory and haemostatic biomarkers.

Using Data

This study examined the association between cardiorespiratory fitness (CRF) without exercise testing and all-cause mortality in Korean older adults. The present study was carried out using data from the 2008 and 2011 Living Profiles of Older People Survey. A total of 14,122 participants aged 60 years and older (57% women) completed the 2008 baseline and 2011 follow-up assessments (i.e., socioeconomic status, health behaviors and conditions, and prevalence of chronic diseases), and they were included for the final analyses. CRF was estimated (eCRF) with sex-specific algorithms and classified as lower (lowest 25%), middle (middle 50%), and upper (highest 25%). Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) across eCRF categories. In total, multivariable-adjusted HRs and 95% CIs were 1 for the upper eCRF group (referent), 1.059 (0.814~1.378) for the middle eCRF group, and 1.714 (1.304~2.253) for the lower eCRF group. In men, multivariable-adjusted HRs and 95% CIs were 1 for the upper eCRF group (referent), 1.011 (0.716~1.427) for the middle eCRF group, and 1.566 (1.098~2.234) for the lower eCRF group. In women, multivariable-adjusted HRs and 95% CIs were 1 for the upper eCRF group (referent), 1.064 (0.707~1.602) for the middle eCRF group, and 1.599 (1.032~2.478) for the lower eCRF group. The current findings suggest that eCRF may have an independent predictor of all-cause mortality, underscoring the importance of promoting physical activity to maintain a healthful level of CRF in Korean geriatric population.

PURPOSE: This study investigated the association between estimated cardiorespiratory fitness (eCRF) and all-cause mortality in underweight older adults.METHODS: Data from the 2006 Korean longitudinal study of aging (KLoSA) involving 348 study participants aged 60 years and older (58.0% women) was analyzed in this study. CRF was estimated with sex- and age-specific algorithms developed by the fitness registry and the importance of exercise national database (FRIEND). Participants were classified into lowest 25% (Q1), lower 25% (Q2), middle 25% (Q3), and highest 25% (Q4) on the basis of individual eCRF distributions. Cox proportional hazards regression was used to calculate hazard ratio (HR) and 95% confidence interval (CI) according to eCRF levels.RESULTS: During 7.8±3.2-year follow-up period, a total of 175 deaths occurred from all causes. Cox regression analysis showed that HR of all-cause mortality was 0.686 (95% CI, 0.474-0.991, <i>p</i>=.045) for Q2, 0.382 (95% CI, 0.253-0.575, <i>p</i><.001) for Q3, and 0.248 (95% CI, 0.155-0.397, <i>p</i><.001) for Q4 compared to Q1 as reference (HR=1). The HR of Q4 for all-cause mortality remained significant even after adjustments for covariates, including age and marital status.CONCLUSIONS: The current findings suggest that high eCRF is associated with a decreased risk of all-cause mortality in underweight older adults.

The Impact

ABSTRACTBackground:Social isolation and homebound statuses are possible risk factors for increased mortality among older adults. However, no study has addressed the impact of accumulation of these two factors on mortality. The aim of this study was to examine whether such accumulation increased the risk of all-cause mortality.Methods:The analyzed sample was drawn from a mail survey of 1,023 older adults without instrumental activities of daily living disability. Participants were classified into four groups according to the frequency of both face-to-face and non-face-to-face interactions with others (social isolation and non-social isolation) and the frequency of going outdoors (homebound and non-homebound). Social isolation and homebound statuses were defined as having a social interaction less than once a week and going outdoors either every few days or less, respectively. All-cause mortality information during a six-year follow-up was obtained.Results:In total, 78 (7.6%) participants were both socially isolated and homebound. During the follow-up period, 65 participants died, with an overall mortality rate of 10.6 per 1000 person-years. Cox proportional hazards regression analyses demonstrated that older adults who were socially isolated and homebound showed a significantly higher risk of subsequent all-cause mortality compared with healthy adults who were neither socially isolated nor homebound, independent of potential covariates (aHR, 2.19; 95% CI: 1.04–4.63).Conclusion:Our results suggest that the co-existence of social isolation and homebound statuses may synergistically increase risk of mortality. Both active and socially integrated lifestyle in later life might play a major role in maintaining a healthy status.

Abstract Background Whether mushroom consumption, which is rich in several bioactive compounds, including the crucial antioxidants ergothioneine and glutathione, is inversely associated with low all-cause and cause-specific mortality remains uncertain. This study aimed to prospectively investigate the association between mushroom consumption and all-cause and cause-specific mortality risk. Methods Longitudinal analyses of participants from the Third National Health and Nutrition Examination Survey (NHANES III) extant data (1988–1994). Mushroom intake was assessed by a single 24-h dietary recall using the US Department of Agriculture food codes for recipe foods. All-cause and cause-specific mortality were assessed in all participants linked to the National Death Index mortality data (1988–2015). We used Cox proportional hazards regression models to calculate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause and cause-specific mortality. Results Among 15,546 participants included in the current analysis, the mean (SE) age was  44.3 (0.5) years. During a mean (SD) follow-up duration of 19.5 (7.4) years , a total of 5826 deaths were documented. Participants who reported consuming mushrooms had lower risk of all-cause mortality compared with those without mushroom intake (adjusted hazard ratio (HR) = 0.84; 95% CI: 0.73–0.98) after adjusting for demographic, major lifestyle factors, overall diet quality, and other dietary factors including total energy. When cause-specific mortality was examined, we did not observe any statistically significant associations with mushroom consumption. Consuming 1-serving of mushrooms per day instead of 1-serving of processed or red meats was associated with lower risk of all-cause mortality (adjusted HR = 0.65; 95% CI: 0.50–0.84). We also observed a dose-response relationship between higher mushroom consumption and lower risk of all-cause mortality (P-trend = 0.03). Conclusion Mushroom consumption was associated with a lower risk of total mortality in this nationally representative sample of US adults.

Abstract We sought to examine the prospective associations of specific fruit consumption, in particular flavonoid-rich fruit (FRF) consumption, with the risk of stroke and subtypes of stroke in a Japanese population. A study followed a total of 39,843 men and 47,334 women aged 44-76 years, and free of cardiovascular disease, diabetes, and cancer at baseline since 1995 and 1998 to the end of 2009 and 2012, respectively. Data on total and specific FRF consumption for each participant were obtained using a self-administrated food frequency questionnaire. The hazard ratios (HRs) of stroke in relation to total and specific FRF consumption were estimated through Cox proportional hazards regression models. During a median follow-up of 13.1 years, 4092 incident stroke cases (2557 cerebral infarctions and 1516 hemorrhagic strokes) were documented. After adjustment for age, body mass index, study area, lifestyles, dietary factors, and other risk factors, it was found that total FRF consumption was associated with a significantly lower risk of stroke in women (HR= 0.70; 95% CI, 0.58-0.84), while the association in men was not significant (HR= 0.93; 95% CI, 0.79-1.09). As for specific FRFs, consumptions of citrus fruits, strawberries, and grapes were found associated with a lower stroke risk in women. Higher consumptions of FRFs, in particular citrus fruits, strawberries, and grapes, were associated with a lower risk of developing stroke in Japanese women.

Background The triglyceride-glucose (TyG) index is a reliable indicator of insulin resistance. We aimed to investigate the TyG index in relation to cardio-cerebrovascular diseases (CCVDs and mortality. Methods This retrospective study included 114,603 subjects. The TyG index was categorized into four quartiles by sex: Q1, <8.249 and <8.063; Q2, 8.249‒<8.614 and 8.063‒<8.403; Q3, 8.614‒< 8.998 and 8.403‒<8.752; and Q4, ≥8.998 and ≥8.752, in men and women, respectively. To calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the primary outcomes (CCVDs and all-cause mortality) and secondary outcomes (cardiovascular diseases [CVDs], cerebrovascular diseases [CbVDs], CCVD-related deaths, or all-cause deaths), Cox proportional hazards regression models were adopted. Results Compared to Q1, the HRs (95% CIs) for the primary outcomes of Q2, Q3, and Q4 were 1.062 (0.981‒1.150), 1.110 (1.024−1.204), and 1.151 (1.058−1.252) in men and 1.099 (0.986−1.226), 1.046 (0.938−1.166), and 1.063 (0.954−1.184) in women, respectively, after adjusted for age, smoking status, drinking status, physical activity, body mass index, systolic blood pressure, low-density lipoprotein cholesterol, economic status, and anti-hypertensive medications. Fully adjusted HRs (95% CIs) for CVDs of Q2, Q3, and Q4 were 1.114 (0.969−1.282), 1.185 (1.031−1.363), and 1.232 (1.068−1.422) in men and 1.238 (1.017−1.508), 1.183 (0.971−1.440), and 1.238 (1.018−1.505) in women, respectively. The adjusted HRs (95% CIs) for ischemic CbVDs of Q2, Q3, and Q4 were 1.005 (0.850−1.187), 1.225 (1.041−1.441), and 1.232 (1.039−1.460) in men and 1.040 (0.821−1.316), 1.226 (0.981−1.532), and 1.312 (1.054−1.634) in women, respectively, while the TyG index was negatively associated with hemorrhagic CbVDs in women but not in men. The TyG index was not significantly associated with CCVD-related death or all-cause death in either sex. Conclusions Elevated TyG index was positively associated with the primary outcomes (CCVDs and all-cause mortality) in men and predicted higher risk of CVDs and ischemic CbVDs in both sexes.
