The Association between Allostatic Load and Mortality among Chinese Older Adults: The Chinese Longitudinal Health and Longevity Study

Abstract Background Allostatic load, as multiple biomarker measures of ‘wear and tear’ on physiological systems, has shown some promise that high burden of AL is associated with increased risk of adverse outcomes, but little attention has been paid to China with largest aging population in the world. This study is to examine the association between allostatic load (AL) and all-cause mortality among Chinese adults aged at least 60 years. Methods Data were from 2,439 participants in the Chinese Longitudinal Healthy Longevity Survey. The final analytic sample consisted of 1,519 participants. Cox models were used to examine the association between AL and mortality among men and women, separately. Analysis were also adjusted for potential confounders including age, ethnicity, education, and marital status, smoking and exercise. Results In the fully adjusted model, males with a medium AL burden (score: 2–4) and high AL burden (score: 5–9) had a 34% and 128% higher hazard of death, respectively, than those with a low AL burden (score: 0–1). We did not find significant difference between females with different levels of AL burden. Discussion Higher AL burden was associated with increased all-cause mortality among Chinese men aged at least 60 years. However, we did not find strong evidence about Allostatic load was associated with specific causes of death over the same follow-up period among women. In conclusion Intervention programs targeting modifiable components of the AL burden may help prolong lifespan for older adults, especially men, in China.

Abstract LGBTQ older adults are at significantly increased risk for poor mental and physical health, likely consequential to lifelong bias. Allostatic load (AL), the net effect of “wear and tear” on the body resulting from repeated, chronic over-activation of the psychophysiological stress response system. Utilizing the Health Equity Promotion Model, the aim of this study was to test potential life course predictors of AL, including interpersonal violence, legal marriage, and identity management in a sample of LGBTQ adults 50 to 97 years of age (n=317). Results from a series of hierarchical linear regression models showed that adult physical abuse and late identity disclosure for those who had been in an opposite-sex marriage predicted higher AL in this sample of LGBTQ older adults, indicating need for increased research on bias over the life course as contributory to AL and biopsychosocial dysfunction among LGBTQ older adults.

Interactive Relationship

Introduction: The interactions between apolipoprotein E (APOE) genotype and diet pattern changes were found significant in several trials, implying that APOE gene may modify the effect of animal protein-rich food on health outcomes. We aim to study the interaction of APOE genotype with the effect of meat, fish and egg intake on mortality.Methods: This population-based study enrolled 8,506 older adults (mean age: 81.7 years, 52.3% female) from the Chinese Longitudinal Healthy Longevity Study. The intake frequency of meat, fish and egg was assessed by 3-point questions at baseline. Cox regression was conducted to calculate the hazard ratios for all-cause mortality of intake levels of meat, fish and egg. The analyses were stratified by APOE genotype and sex. The analyses were performed in 2020.Results: In the multivariable-adjusted models, meat and fish intake was associated with all-cause mortality (high vs. low intake: meat: HR: 1.14, 95% CI: 1.01, 1.28; fish: HR: 0.83, 95% CI: 0.73, 0.95). APOE genotype have significant interactions with meat and fish intake (Ps < 0.05). Compared with low fish intake, high fish intake was associated with lower risk of mortality (HR: 0.74, 95% CI: 0.56–0.98) only among the APOE ε4 carriers. High meat intake was significantly associated with higher risks of mortality (HR: 1.13, 95% CI: 1.04–1.25) only among the APOE ε4 non-carriers. The interactive relationship was restricted among the male. No significant findings were observed between egg and mortality among carriers or non-carriers.Conclusions: Among Chinese older adults, the significance of associations of mortality with reported meat or fish intake depended on APOE-E4 carriage status. If validated by other studies, our findings provide evidence for gene-based “precision” lifestyle recommendations.

The Impact

Abstract Background: Previous studies have evaluated the association of multimorbidity with higher mortality, but epidemiologic data on the association between the combination of multimorbidity and all-cause mortality risk are rare. We aimed to examine the relationship between multimorbidity (number/combination) and all-cause mortality in Chinese older adults. Methods: We conducted a population-based study of 50,100 Chinese participants. Cox regression models were used to estimate the impact of long-term conditions (LTCs) on all-cause mortality. Results: The prevalence of multimorbidity was 31.35% and all-cause mortality was 8.01% (50,100 participants). In adjusted Cox models, the hazard rations (HRs) and 95% confidence intervals (CIs) of all-cause mortality risk for those with 1, 2, and ≥ 3 LTCs compared with those with no LTCs was 1.10 (1.01-1.20), 1.21 (1.10-1.33), and 1.46 (1.27-1.67), respectively (Ptrend <0.001). In the LTCs ≥ 2 category, the combination of chronic diseases that included hypertension, diabetes, CHD, COPD, and stroke had the greatest impact on mortality. In the stratified model by age and sex, absolute all-cause mortality was higher among the ≥ 75 age group with an increasing number of LTCs. However, the relative effect size of the increasing number of LTCs on higher mortality risk was larger among those < 75 years.Conclusions: The risk of all-cause mortality is increased with the number of multimorbidity among Chinese older adults, particularly combinations.

Abstract Background Previous studies have shown increased cardiovascular (CV) risk with both high (>60mg/dl) and low concentrations of high-density lipoprotein cholesterol (HDL-C). The effect of elevated HDL-C levels (>60mg/dL) at differing LDL-C concentrations on outcomes is unknown. Purpose To study the relationship between elevated HDL-C levels (>60mg/dl) in relation to LDL-C concentration (greater vs less than 70mg/dL) and adverse CV outcomes in an at-risk population. Methods Participants included 5,746 individuals (mean age 63.3±12.4 years, 35% female, 23% African American) enrolled in the cardiovascular biobank. Individuals were stratified by HDL-C categories (<30, 31–40, 41–50, 51–60 and ≥60 mg/dL) and LDL-C categories (≥70 and <70 mg/dL). A Cox proportional hazards model was used to examine the association between HDL-C and adverse outcomes, with HDL-C 41–50 mg/dL as the reference group. All models were adjusted for age, race, sex, body mass index, hypertension, smoking, triglycerides, heart failure history, myocardial infarction (MI) history, diabetes, angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker use, beta blocker use, statin use, aspirin use, estimated glomerular filtration rate, obstructive coronary artery disease. Results Over a median follow-up of 6.2 years (25th-75th percentiles = 3.3–8.0 years), a total of 286 MIs, 691 CV deaths and 1,093 all-cause deaths occurred. Individuals with HDL-C ≥60 mg/dL (n=632) had an increased risk of all-cause mortality with an LDL-C ≥70mgdL (HR 1.59; 95% CI=1.10–2.29, p=0.013) after adjustment for the aforementioned variables. This association was not statistically significant with LDL-C <70mg/dL (HR 1.16; 95% CI 0.60–1.21, p=0.66). There was no statistically significant difference for CV death or MI at elevated HDL-C in either group. Conclusion Elevated HDL-C levels is associated with increased all-cause mortality with an LDL-C ≥70mg/dL, though does not appear to be associated with worse outcomes when LDL-C is <70mg/dL.

Abstract Background Frail subjects are at increased risk of adverse outcomes. We aimed to assess their risk of falls, all-cause mortality, and fractures. Methods We used a retrospective cohort study using the SIDIAP database (>6 million residents). Subjects ≥75 years old with ≥1 year of valid data (2007- 2015) were included. Follow-up: from (the latest of) date of cohort entry up to migration, end of the study period or outcome (whichever came first). The eFRAGICAP classified subjects as Fit, Mild, Moderate or Severely Frail. Outcomes (ICD-10) were incident falls, fractures (overall/hip/vertebral) and all-cause mortality during the study period. Statistics: Hazard Ratios (HR), 95% CI adjusted (per age, sex and socio-economic status) and un-adjusted cause-specific Cox models, accounting for competing risk of death (Fit group as the reference). Results 893,211 subjects were analyzed. 54.4% were classified as Fit, 34.0% as mild, 9.9% as moderate and 1.6% as severely frail. Compared with the fit, frail had an increased risk of falls (adjusted HR of 1.55 (1.52-1.58), 2.74 (2.66-2.84) and 5.94 (5.52-6.40)), all-cause mortality (adjusted HR of 1.36 (1.35-1.37), 2.19 (2.16-2.23) and 4.29 (4.13-4.45)) and fractures (adjusted HR of 1.21(1.20-1.23), 1.51(1.47-1.55) and 2.36 (2.20-2.53)) for mild, moderate and severe frailty respectively. Severely frail had a high risk of vertebral (HR of 2.49 (1.99-3.11)) and hip fracture (HR of 1.85 (1.50-2.28)). Accounting for competing risk of death unchanged results. Conclusion Frail subjects are at increased risk of death, fractures and falls. The eFRAGICAP tool can easily assess frailty in electronic primary-care databases in Spain.

Abstract Background Antipsychotics are prescribed to treat various symptoms in older adults, however, their safety in this context has not been fully evaluated. The objective was to evaluate mortality risks associated with off-label use of antipsychotics among older adults with no preexisting mental illness or dementia relative to those with diagnosis of dementia. Methods Data (2007–2015) were derived from Department of Veterans Affairs registries for 730,226 patients (≥65 years) with no baseline serious mental illness, dementia). We estimated the cumulative incidence of antipsychotics prescription and 10-year all-cause mortality. The extended Cox models were used to estimate Hazard Ratios (HRs) associated with antipsychotics prescription, adjusted for time-varying covariates, dementia diagnosis, comorbidity index score, and age at time of first exposure to antipsychotics. Results The study included 98% males, 13% African Americans, and 81% Caucasian. Patients with dementia and antipsychotics had the highest risk of mortality (78.0%), followed by (73.0%) for patients with dementia alone and compared with patients without dementia or antipsychotics exposure who had the lowest mortality risk (42.0%). Exposure to typical antipsychotics was associated with (HR: 2.1, confidence interval [CI] 2.0–2.2) compared with atypical antipsychotics (HR: 1.5, CI 1.4–1.5, p = <.0001). Conclusion In a large cohort of older adults, antipsychotics were associated with an increased risk of all-cause mortality. While significant increase in mortality was attributable to the diagnosis of dementia, the addition of antipsychotics resulted in added mortality risk among all patients. Antipsychotic medications should be used cautiously in all older adults, not only those with dementia.

The Relationship

Abstract Background: Cognitive impairment is a major contributor to mortality among the elderly. However, the trend between cognitive impairment and mortality with time is understudied. We aim to evaluate the differences in associations of cognitive impairment with all-cause mortality and explore the relationship of cognitive impairment with mortality in different age and sex groups in two cohorts ascertained 6 years apart in China. Methods: A total of 13906 and 13873 Chinese elderly aged 65 years and older were included in the 2002-2008 and 2008-2014 cohorts from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Mortality data was ascertained from interviews with family members or relatives of participants. Cognitive function, evaluated by the Mini-Mental State Examination (MMSE), were defined by different cut-offs taking educational background into account. Cox models were used to explore the relationship of cognitive impairment with mortality. Results: For the 2002-2008 and 2008-2014 cohorts, the total follow-up times were 55,277 and 53,267 person-years, and the mean (SD) age were 86.5 (11.6) and 87.2 (11.3) years, respectively. Compared to normal cognition, severe cognitive impairment was independently associated with higher mortality risk after controlling for potential confounders, with hazard ratios (HRs) of 1.48 (95% confidence interval [CI], 1.39-1.57) in 2002-2008 cohort and 1.32 (95% CI, 1.25-1.41) in 2008-2014 cohort. The trend of cognitive impairment with risk of all-cause mortality decreased from 2002-2008 to 2008-2014 cohort. The association of cognitive impairment and mortality was decreased with age in the two cohorts. Conclusions : Cognitive impairment evaluated by MMSE was associated with increased risk of mortality and the association decreased with the passage of time during the two 6-year cohorts; this advocates that periodic screening for cognitive impairment among the elderly is warranted.

Background: Recent data advocate adoption of a more intensive treatment strategy for management of blood pressure (BP). Objective: We investigated whether the overall effects of the Systolic Blood Pressure Intervention Trial (SPRINT) are applicable to cardiovascular disease (CVD) patients. Methods: In a post hoc analysis we analyzed data from SPRINT that randomly assigned 9361 individuals to a systolic BP (SBP) target of <120 mmHg (intensive treatment) or <140 mmHg (standard treatment). 1562 patients had clinically evident CVD (age=70.3±9.3 years, 24% females) at study entry and were followed for 3.1 years. Further, we assessed the effect of low (<150 mmHg) baseline SBP on outcome. Results: In CVD patients, there was no benefit from the intensive treatment regarding all endpoints, except for a marginally significant benefit on all-cause mortality (hazard ratio [HR]: 0.67; 95% confidence interval [CI], 0.45 to 1.00; p=0.0509). Further, while there was no increase in serious adverse events (SAE) in the intensive group, there was increased risk for study-related SAE, acute renal failure and electrolyte abnormalities. In patients with low baseline SBP there was a beneficial effect on allcause mortality (HR: 0.56; 95% CI: 0.33 to 0.96; p=0.033), but with greater stroke incidence (HR: 2.94; 95% CI: 1.04 to 8.29; p=0.042). Conclusion: We confirm the beneficial effect of the intensive strategy in SPRINT study on all-cause mortality and the harmful effect on specific adverse outcomes in patients with CVD. However, in patients with low baseline SBP stroke may increase.

Increased Risk

Two-thirds of older adults have multimorbidity (MM), or co-occurrence of two or more medical conditions. Mild cognitive impairment (CI) is found in almost 20% of older adults and can lead to further cognitive decline and increased mortality. Older adults with MM are the primary users of home health care services and are at high risk for CI development; however, there is no validated cognitive screening tool used to assess the level of CI in home health users. Given the prevalence of MM and CI in the home health setting, we conducted a review of the literature to understand this association. Due to the absence of literature on CI in home health users, the review focused on the association of MM and CI in community-dwelling older adults. Search terms included home health, older adults, cognitive impairment, and multimorbidity and were applied to the databases PubMed, CINAHL, and PsychInfo leading to eight studies eligible for review. Results show CI is associated with MM in older adults of increasing age, among minorities, and in older adults with lower levels of education. Heart disease was the most prevalent disease associated with increased CI. Sleep disorders, hypertension, arthritis, and hyperlipidemia were also significantly associated with increased CI. The presence of MM and CI was associated with increased risk for death among older adults. Further research and attention are needed regarding the use and development of a validated cognitive assessment tool for home health users to decrease adverse outcomes in the older adult population.
