BackgroundDepression may increase the risk of mortality among certain subgroups of older people, but the part played by antidepressants in this association has not been thoroughly explored.AimsTo identify the characteristics of older populations who are most at risk of dying, as a function of depressive symptoms, gender and antidepressant use.MethodAdjusted Cox proportional hazards models were used to determine the association between depression and/or antidepressant use and 4-year survival of 7363 community-dwelling elderly people. Major depressive disorder was evaluated using a standardised psychiatric examination based on DSM-IV criteria and depressive symptoms were assessed using the Center for Epidemiological Studies Depression scale.ResultsDepressed men using antidepressants had the greatest risk of dying, with increasing depression severity corresponding to a higher hazard risk. Among women, only severe depression in the absence of treatment was significantly associated with mortality.ConclusionsThe association between depression and mortality is gender-dependent and varies according to symptom load and antidepressant use.

Background: As the course of depression and depressive symptoms over a lifetime varies between individuals, we used trajectory models based on the Korean Longitudinal Study of Aging to repeatedly measure symptoms over a follow-up period of 12 years to reveal the association with mortality.Methods: Three thousand five hundred sixty-one (1,483 men and 2,078 women) subjects aged over 65 years were included. Using the 10-item Center for Epidemiological Studies Depression Scale (CES-D 10), a trajectory model was classified into different depressive symptom groups by gender. Cox proportional hazards models were used to investigate the association between depression trajectory and all-cause mortality.Results: We identified four trajectories of depressive symptoms in both men and women characterized by low CES-D 10 scores throughout the study: Low trajectory (LT), Moderate high trajectory (MHT), High, but increasing trajectory (HIT), and High, but decreasing trajectory (HDT). The adjusted hazard ratios of the HIT, HDT, and MHT compared with LT in men were 2.12 (95% confidence interval [CI], 1.43-3.16), 1.52 (95% CI, 0.96-2.40), and 1.58 (95% CI, 1.10-2.26), respectively. In women, ratios of each group were 1.62 (95% CI, 1.25-2.10), 0.84 (95% CI, 0.61-1.16), and 1.20 (95% CI, 0.99-1.46).Conclusions: Highly depressive symptoms that increased over the 12 years period were associated with the highest risk of mortality in the Korean elderly population. The trajectory group with remitting depressive symptoms (HDT), despite having a similar baseline level of mood symptoms as the high increasing group (HIT) experienced a lower mortality risk in both men and women.

The Impact

BackgroundDepression is recognized as being associated with increased mortality. However, there has been little previous research on the impact of longitudinal changes in late-life depressive symptoms on mortality, and of their remission in particular.MethodAs part of a prospective, population-based study on a random sample of 5632 subjects aged 65–84 years, with a 10-year follow-up of vital status, depressive symptoms were assessed by the 30-item Italian version of the Geriatric Depression Scale (GDS). The number of participants in the GDS measurements was 3214 at baseline and 2070 at the second survey, 3 years later. Longitudinal changes in depressive symptoms (stable, remitted, worsened) were examined in participants in both evaluations (n=1941). Mortality hazard ratios (MHRs) according to severity of symptoms and their changes over time were obtained by means of Cox proportional hazards regression models, adjusting for age and other potentially confounding factors.ResultsSeverity is significantly associated with excess mortality in both genders. Compared to the stability of depressive symptoms, a worsened condition shows a higher 7-year mortality risk [MHR 1.46, 95% confidence interval (CI) 1.15–1.84], whereas remission reduces by about 40% the risk of mortality in both genders (women MHR 0.55, 95% CI 0.32–0.95; men MHR 0.59, 95% CI 0.37–0.93). Neither sociodemographic nor medical confounders significantly modified these associations.ConclusionsConsistent with previous reports, the severity and persistence of depression are associated with higher mortality risks. Our findings extend the magnitude of the association demonstrating that remission of symptoms is related to a significant reduction in mortality, highlighting the need to enhance case-finding and successful treatment of late-life depression.

Bidirectional Relationship

Abstract Both knee osteoarthritis (KOA) and depressive symptoms are common health issues affecting the quality of life of old adults. Although it is presumed that KOA has a bidirectional relationship with the depressive symptoms, no cohort study has proven it. This is the first study to determine the strength of association for the bidirectional relationship between KOA and depressive symptoms. Data were gathered from the nationally survey of China Health and Retirement Longitudinal Study in 2011-2015. The presence of depressive symptoms was defined by the 10-item Center for Epidemiologic Studies Depression Scale score of 10 or higher. The adjusted Cox proportional hazards regression model was conducted to estimate hazards ratios (HRs). Controlled covariates include gender, age, education, marital status, residence, number of chronic diseases, and disability. The analysis of KOA predicting the depressive symptoms onset consisted of 4,377 participants free from depressive symptoms at baseline. During 4 years follow-up, diagnosed KOA participants were more likely to have depressive symptoms than their peers without KOA (HR = 1.50, 95% CI: 1.23-1.83). The parallel analysis of depressive symptoms predicting KOA onset included 6,848 participants without KOA at baseline, those with depressive symptoms had a higher relative risk of developing KOA (HR = 1.64, 95% CI: 1.41-1.92). Our results provide compelling evidence that the KOA-depressive symptoms association is bidirectional, highlighting the importance of evaluating the relationship between physical and mental health among older people. Particularly, taking this association into consideration in the risk assessment and primary prevention of KOA and depression symptoms.

Abstract Loneliness and depression are both associated with an increased risk of all-cause mortality among older adults. However, the evidence on the joint effect of loneliness and depression is scarce. Furthermore, previous research has rarely examined the modifying effects of gender. We investigated these questions using the Panel on Health and Aging of Singaporean Elderly, a nationally-representative cohort study of community-dwelling older Singaporean adults aged 60 and above, conducted in 2009 with two follow-up waves in 2011 and 2015 (N=4536). We operationalized six groups based on three categories of loneliness measured using the 3-item University of California, Los Angeles (UCLA) loneliness scale: always lonely, sometimes lonely, and never lonely; Two categories of depressive symptom scores were measured using the 11-item Center for Epidemiologic Studies Depression Scale (CES-D) scale: depressed and not depressed. Cox proportional hazards models were employed to estimate the mortality risks for each group, with an extensive set of covariates. Due to significant differences in the prevalence of loneliness and depression in different genders, we conducted gender-stratified analyses. Compared to being not depressed and never lonely, women who were depressed and sometimes lonely and who were not depressed but always lonely had a higher mortality risk. Men who were not depressed but sometimes lonely had a higher mortality risk. We conclude that loneliness appears to be the predominant construct in conferring excess mortality risk. Health policies and interventions addressing the factors common and unique to each gender may improve psychological well-being at older ages, thereby extending the lifespan.

Objective: The independent prognostic value of prehypertension (preHTN) for incident coronary heart disease (CHD) remains unsettled. Using the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort study, we examined associations between preHTN and incident acute CHD and CVD death. Methods: REGARDS includes 30,239 black and white community-dwelling adults age 45 and older at baseline. Recruitment occurred from 2003-7, with baseline interviews and in-home data collection for physiologic measures. Follow-up is conducted by telephone every 6 months to detect events and deaths, which are adjudicated by experts. Systolic BP was categorized into <120 mmHg (n=4385), 120-129 mmHg (n=4000), 130-139 (n=2066), and hypertension was categorized into controlled (<140/90 mmHg on treatment) (n=8378), and uncontrolled (>140/90 mmHg) (n=5364). Incident acute CHD was defined as definite or probable myocardial infarction (MI) or acute CHD death. CVD death was defined as acute CHD, stroke, heart failure or other cardiovascular disease related. Cox proportional hazards models estimated the hazard ratios (HR) for incident CHD by BP categories, adjusting for sociodemographics and CHD risk factors. Results: The 23,393 participants free of CHD at baseline were followed for a median of 4.4 years. Mean age was 64.1, 58% were women and 42% were black. There was a significant interaction between sex and BP categories, therefore analyses were stratified by sex. There were 252 non-fatal and fatal acute CHD events among women and 407 among men. Among women, compared with SBP<120 mmHg, BP categories above SBP 120 mmHg were associated with incident CHD (adjusted HR for SBP120-129 mmHg=1.94 {95% CI 1.04-3.62]; SBP 130-139 mmHg=1.92 {0.95-3.87}; controlled HTN=2.16 {1.25-3.75}; uncontrolled HTN=3.25 {1.87-5.65}) in fully adjusted models. Among men, only uncontrolled HTN was associated with incident CHD (HR=1.55 {1.11-2.17}). Conclusion: In this sample, preHTN may be associated with incident CHD among women but not men.

Background: Depression has been suggested as a potential risk factor for atrial fibrillation (AF) through effects on the autonomic nervous system and hypothalamus-pituitary-adrenal axis. Current literature examining the prospective relationship between depression and AF is inconsistent and limited to studies performed in predominantly white populations. We determined the relationship of both depressive symptoms and anti-depressant use with incident AF in a multi-ethnic cohort. Methods: The Multi-Ethnic Study of Atherosclerosis is a prospective study of 6,814 individuals without clinical cardiovascular disease. Depressive symptoms were assessed at baseline by the 20-item Center for Epidemiologic Studies Depression Scale (CES-D) and use of anti-depressant medications. Five CES-D groups were created based on the score distribution in approximate quartiles, and the top quartile split in 2 such that the top group represented persons with a score ≥16, a value commonly used to identify clinically relevant symptoms. Incident AF was identified from study ECGs verified for AF, ICD-9 hospital discharge diagnoses consistent with AF, and, for participants enrolled in fee-for-service Medicare, inpatient and outpatient AF claims data. Results: 6,644 participants (mean age=62; 53% women; 38% white; 28% black; 22% Hispanic; 12% Chinese-American) were included and followed for a median of 13 years. In separate adjusted Cox proportional hazards analyses, a CES-D≥16 (referent=CES-D<2) and anti-depressant use were each associated with higher incidence of AF (Table). Associations did not differ by race or gender (interaction p-values of 0.18 and 0.17 respectively). Similar results were obtained using time-updated measures of depression. Conclusions: Depressive symptoms are associated with an increased risk of incident AF. Further study into whether improving depressive symptoms reduces AF incidence is important.

Abstract Objectives The literature on n-3 fatty acid (FA) intake and depressive symptoms is inconsistent, potentially due in part to the influence of psychosocial stress. Some evidence supports that n-3 intake may have greater benefit on depressive symptoms among those with high oxidative stress. We quantified the associations between dietary and plasma n-3 FA and 6-y depressive symptoms and measured the modifying effect of psychosocial stress. Methods Data are from the Hispanic Community Health Study/Study of Latinos (age 48 y, 63% female). At baseline (2008–11), EPA, DHA and n-3 very-long-chain FAs (n-3VLCFAs) were estimated using two 24-hr recalls and the NCI method. Plasma n-3 FAs were measured by mass spectrometry. Depressive symptoms were measured at baseline and 6-y follow-up with the 10-item Center for Epidemiological Studies Depression Scale (CESD). Approximately 9 months from baseline, the 10-item Perceived Stress (PSS) and Chronic Burden of Stress scales were obtained. Unstratified and psychosocial stress-stratified associations were analyzed using survey linear regression among those with dietary (n = 3537) and plasma (n = 718) FA data. Model covariates included, but were not limited to, baseline CESD score, ethnicity, study site, antidepressant use, total energy intake, and dietary or plasma n-6 FA. Results Baseline DHA and n-3VLCFA intake were inversely associated with 6-y CESD (P &lt; 0.05). All examined dietary n-3 FA exposures were inversely associated with CESD among those in the highest PSS quartile (Q4) (P &lt; 0.05), but this was attenuated after considering n-6 FA intake. DHA and n-3VLCFA intakes were associated with lower CESD among those with 2 chronic stressors, but not &lt;1 or &gt;2 stressors. Plasma n-3 FAs were not associated with CESD in PSS stratified and unstratified analyses. However, plasma n-3 FA were associated with lower CESD score among those with only 2 chronic stressors. Conclusions Dietary n-3VLCFAs, but not plasma, were inversely associated with 6-y CESD. Psychosocial stress did not clearly modify these associations. These results provide some evidence that greater n-3VLCFA intake may reduce depressive symptoms among Hispanic/Latino adults. However, considering the limitations of self-reported intake, further research is needed using biomarkers of long-term n-3 consumption and psychosocial stress to confirm our findings.

AbstractThis study aimed to examine the longitudinal relationship between disability and depressive symptoms, by comparing four types of disability in community-dwelling individuals with disabilities in South Korea. A total of 3347 South Koreans with disabilities from the second wave of the Panel Survey of Employment for the Disabled was utilized. Depressive symptomatology was assessed by whether the participant had experienced depressive symptoms for more than two weeks during the past year. A multivariate logistic regression model was used to calculate the odds ratio (OR) for depressive symptoms, and a Cox proportional hazards model to calculate the hazard ratio (HR) for two-year survival analysis. Persons who acquired mental disability from accident or industrial disaster and persons with congenital physical-internal disability were at higher risk for depressive symptoms. Maintaining employment was found to be an effective way to decrease the risk of depressive symptoms in persons with physical-external disability, sensory/speech disability, or mental disability. In contrast, in physical-internal disability, retaining normal ability to work seemed to be the key to reduce the risk of depressive symptoms. Predictors of depressive symptoms were found to differ depending on the type of disability. Such differences should be reflected in clinical and policy-level interventions to address the specific psychiatric needs of persons with different disabilities.

Confounding is a major issue in observational epidemiological studies. This paper describes two postestimation commands for assessing confounding effects. One command (confall) displays and plots all possible effect estimates against one of p-value, Akaike information criterion, or Bayesian information criterion. This computing-intensive procedure allows researchers to inspect the variability of the effect estimates from various possible models. Another command (chest) uses a stepwise approach to identify variables that have substantially changed the effect estimate. Both commands can be used after most common estimation commands in epidemiological studies, such as logistic regression, conditional logistic regression, Poisson regression, linear regression, and Cox proportional hazards models.

AbstractObjective.The purpose of this study was to examine depressive symptoms as a risk factor for incident stroke and determine whether depressive symptomatology was differentially predictive of stroke among blacks and whites.Methods.The study was comprised of 9,529 black and 14,516 white stroke-free participants, aged 45 and older, enrolled in REGARDS (2003-2007). Incident stroke was first occurrence of stroke. Association between baseline depressive symptoms (assessed via the 4-item Center for Epidemiological Studies Depression (CES-D-4) scale: 0, 1-3, or >4) and incident stroke was analyzed with Cox proportional hazards models adjusted for demographics, stroke risk factors, and social factors.Results.There were 1,262 strokes over an average follow-up of 9.21 (SD 4.0) years. Compared to participants with no depressive symptoms, after demographic adjustment, participants with CES-D-4 scores of 1-3 had 39% increased stroke risk (HR = 1.39, 95% CI = 1.23-1.57), with slight attenuation after full adjustment (HR = 1.27, 95% CI = 1.11-1.43). Participants with CES-D-4 scores of > 4 experienced 54% higher risk of stroke after demographic adjustment (HR = 1.54, 95% CI = 1.27-1.85), with risk attenuated in the full model similar to risk with 1-3 symptoms (HR = 1.25, 95% CI = 1.03-1.51). There was no evidence of a differential effect by race (p = 0.53).Conclusions.The association of depressive symptoms with increased stroke risk factor was similar among a national sample of blacks and whites. These findings suggest assessment of depressive symptoms should be considered in primary stroke prevention for both blacks and whites.
