Prev Med 2022; 154:106899. [PMID: 34863812 PMCID: PMC8754053 DOI: 10.1016/j.ypmed.2021.106899] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 11/23/2021] [Accepted: 11/28/2021] [Indexed: 01/07/2023]
Abstract
Optimism is associated with reduced mortality risk among Whites, but evidence for this relationship is limited among African-Americans, whose life expectancy is shorter than Whites. This study examined the association between optimism and mortality rate in African-Americans. Data were from African-American women (n = 2652) and men (n = 1444) in the United States from the Jackson Heart Study. Optimism was measured using the Life Orientation Test-Revised at the baseline period (2000-2004), and mortality data were obtained until 2018. Using Cox proportional hazards models, we estimated hazard ratios (HRs) of mortality by optimism level, controlling for sociodemographic factors, depressive symptoms, health conditions, and health behaviors. In secondary analyses, we evaluated potential effect modification by sex, age, income, and education. Higher optimism was related to lower mortality rates (HR = 0.85, 95% confidence interval [CI] = 0.74, 0.99), controlling for sociodemographic factors and depressive symptoms. After further adjusting for health conditions and health behaviors, associations were slightly attenuated (HR = 0.89; 95%CI = 0.77, 1.02). Stronger associations between optimism and mortality were observed in men, among those with higher income or education, and with age ≤ 55 (all p's for interaction terms <0.06). In summary, optimism was associated with lower mortality rates among African-Americans in the Jackson Heart Study. Effect modification by sociodemographic factors should be further explored in additional research considering optimism and mortality in diverse populations. Positive factors, such as optimism, may provide important health assets that can complement ongoing public health efforts to reduce health disparities, which have traditionally focused primarily on risk factors.

Abstract
Young adults are prone to psychological stress and anxiety induced by major transitions to adulthood. While employment has predominated in previous research on the social determinants of young people’s mental health, this study examines the association between young people’s housing problems and mental health in the context of an unaffordable housing market. Using the Survey on the Living Conditions and Welfare Needs of Youths (n = 1308) in Korea, the study found that perceived poor housing quality and material hardship are negatively associated with the mental health of young adults living independently. Specifically, while poor housing quality and material hardship induced by housing cost burden were negatively associated with single-person households’ mental health, only poor housing quality was associated with non-single-person households’ mental health. This study is one of the few studies examining the linkage between housing problems and mental health of young adults and informs the interventions aimed at promoting the psychological well-being of young adults in the transition from parents’ homes to independent living.

Abstract
No studies have examined whether positive emotions lead to favorable cardiovascular health (CVH) early in the lifespan, before cardiovascular disease is diagnosed. Moreover, the direction of the association has not been thoroughly investigated. Among younger adults, we investigated whether baseline positive emotions were associated with better CVH over 20 years. We also considered whether baseline CVH was associated with subsequent positive emotions during the same period. Participants included 4196 Black and White men and women from the Coronary Artery Risk Development in Young Adults Study. Positive emotions and cardiovascular-related parameters were each assessed in 1990 (this study's baseline), with repeated assessment through 2010. CVH was defined by blood pressure, lipids, body mass index, diabetes, and smoking status. Primary analyses used linear mixed effects models adjusting for potential confounders; secondary analyses stratified by race and sex. Controlling for sociodemographic factors, greater baseline positive emotions were associated with better CVH across time (β = 0.03, 95% confidence interval = 0.007-0.06). However, positive emotions were unrelated to rate of change in CVH across time. Baseline CVH was also associated with greater average positive emotions across time (β = 0.09, 95% confidence interval = 0.02-0.15), but not rate of change. Positive emotions' association with CVH was stronger for women than men, but race did not modify associations. Positive emotions in early to middle adulthood were associated with better CVH across several decades. Baseline CVH was also associated with greater positive emotions during follow-up. Future research may be able to disentangle these relationships by assessing positive emotions and CVH earlier in life.

Abstract
Studies on the cognitive working mechanism of smoking cessation in high-risk populations are few and much needed, and identifying long-term psychosocial factors to smoking cessation are relevant to improve intervention for cardiac patient groups. This longitudinal study followed patients who smoked and suffered an acute coronary syndrome from hospitalization to 12 months after clinical discharge. Questionnaires were administered to assess nicotine dependence, behavioral dependence, autonomous self-regulation, perceived competence, social support, anxiety, depressive symptoms and meaning in life at baseline, six months and twelve months after clinical discharge. The results showed that anxiety (F(2, 62) = 28.10, p < .001, η p 2 = .48) and depressive symptoms (F(2, 62) = 10.42, p < .001, η p 2 = .25) decreased over time, whereas meaning in life (F(2, 61) = 44.77, p < .001, η p 2 = .59) and social support increased (t(63) = -4.54, p < .001, 95% IC[-11.05, 4.29], η2 =.25). Smoking dependence was negatively predicted by change in perceived competence (B = -2.25, p = .011, 95% IC[.02, .60]) and positively by change in depressive symptoms (B =.37, p = .042, 95% IC[1.01, 2.05]) 12 months after clinical discharge. Nicotine dependence (t(17) = 2.76, p = .014, 95% IC[.39, 2.94], η2 =.31) and the number of cigarettes smoked per day (t(17) = 4.48, p < .001, 95% IC[5.49, 15.29], η2 =.54) decreased over time, whereas behavioral dependence increased among smokers (t(17) = -2.37, p = .030, 95% IC[-4.30, 2.54], η2 =.25). This study suggests that long term abstinence in cardiac patients may be enhanced by psychological interventions addressing perceived competence, depressive symptoms and behavioral dependence.

Abstract
There have been calls to know more about vulnerability factors that may predispose to adverse health outcomes at work. We examined if childhood adverse experiences would affect vulnerability to psychosocial stress factors at work. A nationally representative sample of 1546 Finnish men and women was followed up from childhood to adulthood. Childhood adverse experiences consisted of socioeconomic and emotional factors. Job demands and job control were measured 21 years later, and depressive symptoms were measured 21 and 27 years after the childhood measurements. Job demands predicted depressive symptoms over 6 years, and the association was modified by childhood emotional adversity. Participants with three or more emotional adversities in childhood had more depressive symptoms in response to high job demands compared with participants with zero or one emotional adversities in childhood (Betas = -1.40 and -2.01, ps < 0.05 and <0.01). No such moderating effect by childhood adverse experiences was found for the association between job control and depressive symptoms. Although modest in effect size, these findings provide a developmental viewpoint for understanding the role of childhood experiences in work-related stress factors. Such knowledge can enhance understanding of individual differences in vulnerability to the demands of working life. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
BACKGROUND Depressive symptoms are an independent risk factor of cardiovascular disease (CVD). More than 15% of persons with CVD have depressive symptoms, which are twice as likely to occur in women. Depressive symptoms in women being screened for CVD have not been well studied. OBJECTIVE The relationships between depressive symptoms, health-promoting lifestyle behaviors, heart disease risk awareness, cardiac risk, and quality of life (QOL) in women were investigated. Whether the effect of depressive symptoms on QOL was mediated by cardiac risk and/or health-promoting lifestyle behaviors was also examined. METHODS The Wilson-Cleary Health-Related Quality of Life Model guided this descriptive study. A convenience sample of 125 women was recruited from cardiac health screening events. The study measurements were the Center for Epidemiologic Studies Depression Scale; the Framingham risk score; the Ferrans-Powers Quality of Life Index Generic Version-III; the Health-Promoting Lifestyle Profile-II; and questions related to heart disease risk, awareness of heart disease risk, health history, and demographics. Body mass index, percentage of body fat, and lipid profile were also measured. RESULTS More than one-third (34%) of the women reported significant depressive symptoms. Depressive symptoms were not associated with cardiac risk or risk awareness but were inversely associated with health-promoting lifestyle behaviors (r = -0.37, P < 0.01) and QOL (r = -0.51, P < 0.01). There was a dose-response relationship with health-promoting lifestyle behaviors (odds ratio, 0.92; 95% confidence interval, 0.88-0.97; P < 0.001) and QOL (odds ratio, 0.85; 95% confidence interval, 0.79-0.92; P < 0.001) and depressive symptoms. Health-promoting lifestyle behaviors mediated the association between depressive symptoms and QOL. CONCLUSIONS Depressive symptoms contribute significantly to health-promoting lifestyle behaviors and QOL for women. Early detection and treatment of depressive symptoms are important for participation in healthy lifestyle behaviors, which could result in improved QOL.

Abstract
OBJECTIVE Adverse experiences in childhood may influence cardiovascular risk in adulthood. We examined the prospective associations between types of psychosocial adversity and having multiple adversities (e.g., cumulative risk) with carotid intima-media thickness (IMT) and its progression among young adults. Higher cumulative risk score in childhood was expected to be associated with higher IMT and its progression. METHODS Participants were 2265 men and women (age range, 24-39 years in 2001) from the ongoing Cardiovascular Risk in Young Finns study whose carotid IMTs were measured in 2001 and 2007. A cumulative psychosocial risk score, assessed at the study baseline in 1980, was derived from four separate aspects of the childhood environment that may impose risk (childhood stressful life events, parental health behavior family, socioeconomic status, and childhood emotional environment). RESULTS The cumulative risk score was associated with higher IMT in 2007 (b = 0.004, standard error [SE] = 0.001, p < .001) and increased IMT progression from 2001 to 2007 (b = 0.003, SE = 0.001, p = .001). The associations were robust to adjustment for conventional cardiovascular risk factors in childhood and adulthood, including adulthood health behavior, adulthood socioeconomic status, and depressive symptoms. Among the individual childhood psychosocial risk categories, having more stressful life events was associated with higher IMT in 2001 (b = 0.007, SE = 0.003, p = .016) and poorer parental health behavior predicted higher IMT in 2007 (b = 0.004, SE = 0.002, p = .031) after adjustment for age, sex, and childhood cardiovascular risk factors. CONCLUSIONS Early life psychosocial environment influences cardiovascular risk later in life, and considering cumulative childhood risk factors may be more informative than individual factors in predicting progression of preclinical atherosclerosis in adulthood.

Abstract
Background—
The American Heart Association has defined a new metric of ideal cardiovascular health as part of its 2020 Impact Goals. We examined whether psychosocial factors in youth predict ideal cardiovascular health in adulthood.
Methods and Results—
Participants were 477 men and 612 women from the nationwide Cardiovascular Risk in Young Finns Study. Psychosocial factors were measured from cohorts 3 to 18 years of age at the baseline of the study, and ideal cardiovascular health was examined 27 years later in adulthood. The summary measure of psychosocial factors in youth comprised socioeconomic factors, emotional factors, parental health behaviors, stressful events, self-regulation of the child, and social adjustment of the child. There was a positive association between a higher number of favorable psychosocial factors in youth and greater ideal cardiovascular health index in adulthood (β=0.16;
P
<0.001) that persisted after adjustment for age, sex, medication use, and cardiovascular risk factors in childhood (β=0.15;
P
<0.001). The association was monotonic, suggesting that each increment in favorable psychosocial factors was associated with improvement in cardiovascular health. Of the specific psychosocial factors, a favorable socioeconomic environment (β=0.12;
P
<0.001) and participants’ self-regulatory behavior (β=0.07;
P
=0.004) were the strongest predictors of ideal cardiovascular health in adulthood.
Conclusions—
The findings suggest a dose-response association between favorable psychosocial factors in youth and cardiovascular health in adulthood, as defined by the American Heart Association metrics. The effect seems to persist throughout the range of cardiovascular health, potentially shifting the population distribution of cardiovascular health rather than simply having effects in a high-risk population.

Abstract
Psychosocial disadvantage and lower socioeconomic status are associated with increased risk of poor health. The purposes of this study are to identify a threshold at which cumulative psychosocial risk factors become significantly associated with a decrease in health status and to examine whether women are at higher risk than men. Using secondary cross-sectional data, a correlation of self-reported health rating and psychosocial risk factors was conducted. Participant characteristics by number of health-related psychosocial risks were constructed. The accumulation of risk factors had a negative effect on health status at the threshold of two; health status significantly decreased with the addition of each risk factor. Gender significantly moderated the relationship between number of risks and self-reported health status, with women's health decreasing as the number of risks increased. Risk factors in this study are typically part of client assessments and can be used in assisting social workers to identify those most at risk. Those with two or more risk factors are significantly more at risk for poorer health. Moreover, women and ethnic minorities were at more risk for poor health with the addition ofjust one risk factor.

Abstract
BACKGROUND It is not known whether various forms of emotion regulation are differentially related to cardiovascular disease risk. PURPOSE The purpose of this study is to assess whether antecedent and response-focused emotion regulation would have divergent associations with likelihood of developing cardiovascular disease. METHODS Two emotion regulation strategies were examined: reappraisal (antecedent-focused) and suppression (response-focused). Cardiovascular disease risk was assessed with a validated Framingham algorithm that estimates the likelihood of developing CVD in 10 years. Associations were assessed among 373 adults via multiple linear regression. Pathways and gender-specific associations were also considered. RESULTS One standard deviation increases in reappraisal and suppression were associated with 5.9 % lower and 10.0 % higher 10-year cardiovascular disease risk, respectively, in adjusted analyses. CONCLUSIONS Divergent associations of antecedent and response-focused emotion regulation with cardiovascular disease risk were observed. Effective emotion regulation may promote cardiovascular health.

Abstract
U.S. veterans present with complex medical and psychosocial concerns postdeployment. Identification of psychosocial concerns is necessary for appropriate and targeted social work interventions to improve delivery and receipt of health care through the U.S. Department of Veterans Affairs. The purpose of this article is to identify specific psychosocial concerns of veterans of Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) presenting at the War Related Illness and Injury Study Center. A retrospective chart review of psychosocial concerns from all OIF/OEF veterans seen fromJune 2008 toJune 2010 provided data for this mixed methods study. Veterans in the sample (N= 356) reported an average of 5.2 psychosocial concerns (SD = 2.32, range = 0 to 11). The most commonly reported concerns were pain (72 percent), sleep (62 percent), cognition (61 percent), vocational issues (53 percent), education (49 percent), finances (42 percent), relationships (37 percent), anger (30 percent), substance abuse (23 percent), and social support (20 percent), though these categories were not exclusive and many veterans endorsed more than one category. Multiple psychosocial concerns reported by veterans suggest the need for targeted social work intervention.

Abstract
OBJECTIVE Emerging evidence suggests that psychosocial stress may influence weight gain. The relationship between stress and weight change and whether this was influenced by demographic and behavioral factors was explored. DESIGN AND METHODS A total of 5,118 participants of AusDiab were prospectively followed from 2000 to 2005. The relationship between stress at baseline and BMI change was assessed using linear regression. RESULTS Among those who maintained/gained weight, individuals with high levels of perceived stress at baseline experienced a 0.20 kg/m(2) (95% CI: 0.07-0.33) greater mean change in BMI compared with those with low stress. Additionally, individuals who experienced 2 or ≥3 stressful life events had a 0.13 kg/m(2) (0.00-0.26) and 0.26 kg/m(2) (0.14-0.38) greater increase in BMI compared with people with none. These relationships differed by age, smoking, and baseline BMI. Further, those with multiple sources of stressors were at the greatest risk of weight gain. CONCLUSION Psychosocial stress, including both perceived stress and life events stress, was positively associated with weight gain but not weight loss. These associations varied by age, smoking, obesity, and multiple sources of stressors. Future treatment and interventions for overweight and obese people should consider the psychosocial factors that may influence weight gain.

Abstract
The public health burden of cardiovascular disease (CVD) is high both in terms of economic and social costs. Key modifiable factors identified for CVD prevention include health behaviors and health risk factors (e.g., cholesterol, blood pressure). However, a substantial body of research has also identified stress, anxiety, and depression as potentially modifiable CVD risk factors. Here we focus on the role of anxiety in the development of CVD and consider its potential as a key target for primordial prevention strategies. First, we highlight important findings and summarize the latest research on anxiety and incident CVD. We also review and summarize the findings to date on subclinical CVD outcomes and briefly consider mechanisms by which anxiety may influence CVD. We identify key issues and consider how these issues may inform our understanding of the anxiety-CVD relationship. Finally, we briefly discuss the clinical implications of this work, with specific recommendations for providers.

Abstract
BACKGROUND Dysregulated emotional functioning has been linked with higher cardiovascular disease (CVD) risk among adults. Early life experiences may influence the development of adulthood CVD, but few studies have examined whether potential damaging effects of dysregulated emotional function begin earlier in life. Therefore, we examined associations of child emotional functioning and the 10-year risk of developing CVD in midlife. METHODS We studied 377 adult offspring (mean age=42.2) of Collaborative Perinatal Project participants, a US cohort of pregnant women enrolled in 1959-1966. Three measures of child emotional functioning derived from psychologist ratings of behaviour at 7 years of age were examined: distress proneness, attention and inappropriate self-regulation. Adulthood 10-year CVD risk was calculated with the validated Framingham general CVD risk algorithm. Gender-specific multiple regression models assessed associations of childhood emotion and adulthood CVD risk independent of covariates measured across the life course. Potential mediators of the associations were also examined. RESULTS Women had 31% higher CVD risk per SD increase in childhood distress proneness (p=0.03) and 8% reduced risk per SD increase in attention (p=0.09). For men, each SD increase in childhood distress proneness was associated with 17% higher CVD risk (p=0.02). Associations were partly explained by adulthood body mass index and depressive symptoms in women but not in men. Inappropriate self-regulation was not associated with CVD risk. CONCLUSIONS Several aspects of childhood emotional functioning was associated with adulthood CVD risk, particularly for women. As such, primary prevention of CVD may be associated with addressing early life emotional functioning.

Abstract
Psychosocial factors are increasingly recognized as risk indicators for coronary artery disease (CAD) prognosis and they are likely interrelated. The objective of this study is to simultaneously test the relationship between key psychosocial constructs as independent factor scores and recurrent events in CAD patients. There were 1268 CAD outpatients of 97 cardiologists surveyed at two points. Recurrent events or hospitalization in the intervening nine months were reported. Factor analysis of items from the Hospital Anxiety and Depression Scale, Perceived Stress Scale, the ENRICHD Social Support Inventory, and Hostile Attitudes Scale was performed to generate orthogonal factor scores. With adjustment for prognostic variables, logistic regression analysis was performed to examine the relationship between these factor scores and recurrent events. Factor analysis resulted in a six-factor solution: hostility, stress, anxiety, depressive symptoms, support, and resilience. Logistic regression revealed that functional status and anxiety, with a trend for depressive symptoms, were related to experiencing a recurrent event. In this simultaneous test of psychosocial constructs hypothesized to relate to cardiac prognosis, anxiety may be a particularly hazardous psychosocial factor. While replication is warranted, efforts to investigate the potential benefits of screening and to investigate treatments are needed.

Abstract
OBJECTIVE To test the hypothesis that a greater perceived responsibility for household tasks and a greater number of hours spent doing these tasks would be associated with elevated ambulatory systolic (SBP) and diastolic blood pressure (DBP). The connection between job characteristics and cardiovascular outcomes has been widely studied. However, less is known about links between household work characteristics and cardiovascular health. METHODS A total of 113 employed unmedicated hypertensive men and women underwent 1 day of ambulatory blood pressure (ABP) monitoring. Participants provided information on 1) the number of hours spent doing; and 2) their degree of responsibility for seven household tasks (child care; pet care; caring for ill/elderly; household chores; house/car repair; yard work; finances). Associations between task hours and responsibility ratings in relation to SBP and DBP were estimated, using generalized estimating equations, with covariates age, race, gender, body mass index, location, and posture. Interactions with gender and socioeconomic position were assessed. RESULTS A greater perceived responsibility for household tasks, but not the hours spent doing these tasks, was associated with higher ambulatory SBP (b (95% confidence interval [CI]), 0.93 (0.29-1.56), p = .004) and DBP (b (95% CI), 0.30 (0.10-0.51), p = .003). Significant interactions with income indicated that associations between household responsibilities and ABP were most pronounced among low income participants (SBP: b (95% CI), 1.40 (0.58-2.21), p < .001; DBP: b (95% CI), 0.48 (0.18-0.78), p < .01). The task associated most strongly with BP was household chores. No interactions with gender were observed. CONCLUSIONS Greater perceived responsibility for household tasks was associated with elevated ABP, particularly for lower income participants. Household obligations may have important implications for cardiovascular health, meriting further empirical attention.

Abstract
OBJECTIVE To describe the pathophysiological basis linking cardiovascular disease (CVD) and depression; to discuss the causal relationship between them, and to review the effects of antidepressant treatment on cardiovascular disease. METHOD A review of the literature based on the PubMed database. DISCUSSION Depression and cardiovascular disease are both highly prevalent. Several studies have shown that the two are closely related. They share common pathophysiological etiologies or co-morbidities, such as alterations in the hypothalamic-pituitary axis, cardiac rhythm disturbances, and hemorheologic, inflammatory and serotoninergic changes. Furthermore, antidepressant treatment is associated with worse cardiac outcomes (in case of tricyclics), which are not observed with selective serotonin reuptake inhibitors. CONCLUSION Although there is a strong association between depression and cardiovascular disease, it is still unclear whether depression is actually a causal factor for CVD, or is a mere consequence, or whether both conditions share a common pathophysiological etiology. Nevertheless, both conditions must be treated concomitantly. Drugs other than tricyclics must be used, when needed, to treat the underlying depression and not as mere prophylactic of cardiac outcomes.

Abstract
BACKGROUND AND PURPOSE Psychosocial stress has been widely studied as a risk factor for stroke and coronary heart disease (CHD) but little is known about the differential effects of stress on stroke and CHD risk by race and sex. Caregiving for a disabled spouse has been associated with increased mortality and CHD risk, but the association of caregiving strain with stroke and CHD risk across race and sex is unknown. METHODS Participants in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study who were providing in-home caregiving to a disabled spouse reported on caregiving strain (high, some, or none), depressive symptoms, social network, education, and age. Caregiving strain groups were compared on the Framingham Stroke Risk Score (N=716) and Framingham CHD Risk Score (N=607), which estimate the projected 10-year risk of incident stroke and ischemic heart disease, respectively. RESULTS High caregiving strain was associated with a 23% higher covariate-adjusted estimated stroke risk (11.06% for caregivers with no strain versus 13.62% risk for high-strain caregivers). This association was stronger in men, particularly African American men with high caregiving strain (26.95% estimated 10-year stroke risk). Caregiving strain was not associated with CHD risk scores. CONCLUSIONS Caregiving strain is significantly associated with higher estimated stroke risk with greatest effects for men, particularly African American men, providing caregiving to their wives. Male spouse caregivers may need special caregiving support. Prospective longitudinal studies should examine how sex and race may moderate the impact of stress on stroke and CHD risk.

Abstract
There is evidence to support the view that both hostility and depressive symptoms are psychological risk factors for ischaemic heart disease (IHD), additional to the effects of lifestyle and biomedical risk factors. Both are also more common in lower socioeconomic groups. Studies to find out how socioeconomic status (SES) gets under the skin have not yet determined the relative contributions of hostility and depression to the income gradient in IHD. This has been examined in a Dutch prospective population-based cohort study (GLOBE study), with participants aged 15-74 years (n=2374). Self-reported data at baseline (1991) and in 1997 provided detailed information on income and on psychological, lifestyle and biomedical factors, which were linked to hospital admissions due to incident IHD over a period of 12 years since baseline. Cox proportional hazard models were used to study the contributions of hostility and depressive symptoms to the association between income and time to incident IHD. The relative risk of incident IHD was highest in the lowest income group, with a hazard ratio of 2.71. Men on the lowest incomes reported more adverse lifestyles and biomedical factors, which contributed to their higher risk of incident IHD. An unhealthy psychological profile, particularly hostility, contributed to the income differences in incident IHD among women. The low number of IHD incidents in the women however, warrants additional research in larger samples.

Abstract
The association of psychosocial stress with weight gain may have important implications for clinical practice and workplace and public health interventions. To determine whether multiple domains of psychosocial stress were associated with weight gain from 1995 to 2004, the authors analyzed a nationally representative longitudinal cohort of 1,355 men and women in the United States. Change in body mass index was assessed for multiple domains of psychosocial stress related to work, personal relationships, life constraints, and finances, controlling for other factors associated with weight gain. All analyses were stratified by sex and weighted to account for the complex survey design. Among men with high baseline body mass index, weight gain was associated with increasing levels of psychosocial stress related to job-related demands (P < 0.001 for interaction with baseline body mass index), lack of skill discretion (P = 0.014), lack of decision authority (P = 0.026), and difficulty paying bills (P = 0.004). Among women with high baseline body mass index, weight gain was associated with job-related demands (P < 0.001 for interaction with baseline body mass index), perceived constraints in life (P < 0.001), strain in relations with family (P = 0.016), and difficulty paying bills (P = 0.010). Interventions to address psychosocial stress may limit weight gain among overweight and obese men and women.

Abstract
BACKGROUND Incident anxiety and depression are associated separately with cardiac events and mortality in patients after acute coronary syndromes, but the influence of persistent comorbid depression and anxiety on mortality remains unknown. The purpose of this study was to determine the prevalence of comorbid persistent depressive and anxious symptoms in individuals with ischemic heart disease and to evaluate effects on mortality. METHODS Prospective, longitudinal cohort design in the context of a randomized trial to decrease patient delay in seeking treatment for ischemic heart symptoms (PROMOTION trial) was used, with twelve-month follow-up of 2325 individuals with stable ischemic heart disease. Participants were assessed on enrollment and at 3 months using the Multiple Adjective Affect Checklist and the Brief Symptom Inventory for depressive and anxious symptoms, respectively. RESULTS At 3 months, 608 individuals (61.7%) reported persistent symptoms of depression, anxiety, or both. Three hundred seventy-nine (42.5%) and 1056 (45.4%) had persistent anxious and depressive symptoms, respectively. Those with persistent, comorbid symptoms had higher mortality compared to others (p=.029). The combined presence of anxious and depressive symptoms contributed significantly to mortality when compared to symptom-free participants (OR 2.35, 95% CI 1.23-4.47, p=.010). The presence of persistent depressive symptoms only and persistent anxious symptoms only were not associated with death, when other demographic and clinical variables were considered. CONCLUSIONS Persistent symptoms of anxiety and depression increased substantially the risk of death in patients with ischemic heart disease. Future research into shared and unique pathways and treatments is needed.

Abstract
There is growing evidence that the present risk assessment protocol for coronary heart disease appears to underestimate the risk in general and the presence and progression of atherosclerosis in particular. Little or no correlation has been found between the 10-year risk based on the Framingham model and the extent or progression of coronary calcification. In addition, a number of studies find the protocol based on current guidelines leads to an under appreciation of the risk of symptomatic coronary heart disease or the associated fatal and non-fatal events, especially in younger asymptomatic individuals and women. Furthermore, the current guidelines give secondary importance to insulin resistance and inflammation and do not include psychosocial stress and depression, both of which are established and important risk factors for coronary heart disease. An alternative approach to risk assessment is proposed which emphasizes insulin resistance and psychological stress and depression and gives much greater recognition to inflammation as a root cause and target for intervention than is found in current guidelines. Consistent with this view, a revised assessment protocol is suggested which is still appropriate to the primary care setting and which might provide a different and perhaps more effective and relevant approach to primary prevention and risk reduction.

Abstract
Psychosocial stress is associated with risk of obesity although little is known about stress-induced biological mechanisms of obesity. We examined the potential mediating role of inflammatory processes. Data were collected from a nationally representative sample of 7540 individuals (54% women, mean age 46.8+/-15.4 years), from the Scottish Health Surveys. We calculated risk estimates of obesity for increasing numbers of psychosocial stressors (based on social position, education, psychological distress and marital/partner discord) using logistic regression analyses. Obesity was assessed using body mass index and central obesity using waist circumference. Potential mediators included inflammatory markers (C-reactive protein and fibrinogen) and health behaviours (physical activity, smoking, alcohol, and dietary intake). The unadjusted odds ratio of obesity for three or more psychosocial stressors was 1.81 (95% CI, 1.39-2.36, p<0.001). In multivariate analyses that adjusted for age, gender, health behaviours and inflammatory markers the association between psychosocial stress and obesity was attenuated but remained significant (1.49, 1.11-2.00, p<0.001). Inflammatory markers independently accounted for approximately 25% of the association between stress and obesity. We found similar associations in separate analyses of psychosocial stress and central obesity, although results were confounded by overall obesity. In summary, inflammatory processes appear to be an important intermediate pathway in the association between psychosocial stress and obesity.
