Depression and increased risk of death in adults with stroke

Objective

Depression is a common condition among individuals with stroke and believed to influence post-stroke mortality. The objective of this study was to evaluate the effect of depression on all-cause mortality among adults with and without a history of stroke.

Methods

We studied 10,025 participants in the population-based National Health and Nutrition Examination Survey I Epidemiologic Follow-up Study who were alive and interviewed in 1982 and had complete data for the Center for Epidemiologic Studies Depression Scale. Four groups were created based on history of stroke and depression status in 1982: (1) no stroke, no depression (reference group); (2) no stroke, depression present; (3) history of stroke, no depression; and (4) history of stroke present, depression present. Cox proportional hazards regression models were used to calculate multivariate-adjusted hazard ratios (HRs) of death for each group compared with the reference group.

Results

Over 8 years (83,624 person-years of follow-up), 1,925 deaths were documented. Mortality rate per 1,000 person-years of follow-up was highest in the group with both a history of stroke and depression. Compared with the reference group, HRs for all-cause mortality were: no stroke, depression present, 1.23 (95% CI 1.08–1.40); stroke present, no depression 1.74 (1.06–2.85); and stroke present, depression present, 1.88 (1.27–2.79).

Conclusions

The coexistence of stroke and depression increases the risk of death; however, the combined effect is less than additive.     

Gastrointestinal symptoms in primary care: prevalence and association with depression and anxiety

OBJECTIVE: Results from general population studies suggest a relationship between gastrointestinal (GI) symptoms, depression, and anxiety. However, no primary care study has investigated this issue. This study investigates the prevalence of GI symptoms in primary care and their association with depression and anxiety. METHOD: Within a cross-sectional survey, 2091 consecutive patients from 15 primary care clinics in the United States completed self-report questionnaires regarding GI symptoms [15-item Patient Health Questionnaire (PHQ-15)], anxiety [seven-item Generalized Anxiety Disorder Scale (GAD-7)], and depression (PHQ-8). Of those, 965 randomly selected patients additionally underwent a criterion standard diagnostic telephone interview (Structured Clinical Interview for DSM-IV) for the most common anxiety disorders. RESULTS: A total of 380 [18% (95% CI, 16.3% to 19.3%)] patients reported to be substantially bothered by at least one GI symptom in the previous 4 weeks. The prevalence of severe levels of depression (PHQ-8 score > or =15) was nearly fivefold in patients with GI symptoms compared to patients without GI symptoms (19.1% vs. 3.9%; P<.001), and the prevalence of severe levels of anxiety (GAD-7 score > or =15) was nearly fourfold in patients with GI symptoms compared to patients without GI symptoms (19.4% vs. 5.6%; P<.001). Similarly, with each additional GI symptom, the odds for an interview-based diagnosis of specific anxiety disorders increased significantly: For example, compared to patients with no GI symptom, the odds ratio (OR) (95% CI) for generalized anxiety disorder in patients with one GI symptom was 3.7 (2.0 to 6.9); in patients with two GI symptoms, OR=6.5 (3.1 to 13.6); and in patients with three GI symptoms, OR=7.2 (2.7 to 18.8). CONCLUSION: GI symptoms are associated significantly with depression and anxiety in primary care. It is suggested to screen as a routine for anxiety and depression in patients with GI symptoms and, if indicated, to initiate specific treatment.     

Psychosocial interventions for depression, anxiety, and quality of life in cancer survivors: meta-analyses

OBJECTIVE: The purpose of this meta-analysis was to investigate the effects of cognitive behavioral therapy (CBT) and patient education (PE) on commonly reported problems (depression, anxiety, pain, physical functioning, and quality of life (QOL)) in adult cancer survivors. METHODS: Meta analyses of randomized controlled trials of CBT and PE were conducted. MEDLINE, PSYCHINFO and the Cochrane Database were searched from 1993-2004. The effects of individual versus group interventions and short (<8 months) versus long (>8 months) term follow up are also reported. RESULTS: Fifteen studies met quality criteria. The sample size was 1,492 adult cancer survivors with an age range of 18-84. 790 were randomly assigned to intervention groups and 702 to control groups. CBT varied in duration from 4 weekly one-hour sessions to 55 weekly two-hour sessions. PE ranged from a single 20-minute session to 6 weekly one-hour sessions. Follow up ranged from 1 week to 14 months. CBT was effective for depression (ES = 1.2; 95% CI = 0.22-2.19), anxiety (ES = 1.99; 95% CI = 0.69-3.31), and QOL (ES = 0.91; 95% CI = 0.38-1.44). QOL was improved at both short and (ES = 1.45, 95% CI = .43-2.47) and long term (ES = .26; 95% CI = .06-.46) follow up. PE was not related to improved outcomes. CONCLUSIONS: CBT is related to short-term effects on depression and anxiety and both short and long term effects on QOL. Individual interventions were more effective than group. Various CBT approaches provided in an individual format can assist cancer survivors in reducing emotional distress and improving quality of life.     

Relationship between abdominal pain subgroups in the community and psychiatric diagnosis and personality. A birth cohort study

INTRODUCTION: It is unclear if there is a causal link between psychiatric disorders and unexplained chronic gastrointestinal (GI) symptomatology. The role of personality is also in dispute. We aimed to assess the association of these factors with functional GI symptoms in a birth cohort study. METHODS: The Dunedin birth cohort is well characterised and has been followed-up prospectively to age 26 (n=980). Measured were upper and lower GI symptoms over the prior year at age 26 using a validated questionnaire, psychiatric diagnoses at ages 18 and 21 by standardised interview applying DSM-III-R criteria, and personality at age 18 using the Multidimensional Personality Questionnaire (MPQ). Natural symptom groupings were identified using factor analysis and k-means clustering. The association of these clusters and psychiatric diagnoses or personality was assessed by logistic regression. RESULTS: The k-means analysis produced a six-cluster solution, which was made up of a health group, and five "disease" clusters defined by higher than average scores on a single symptom. A diagnosis of depression at age 18 or 21 years was associated with increases in the odds of 1.69 (95% CI: 1.27-2.25) for all GI, of 2.16 (95% CI: 1.12-4.16) for dysmotility and of 2.07 (95% CI: 1.13-3.80) for constipation, but not with the other clusters. Similar results were observed with respect to anxiety disorders for the odds of GI overall (OR=1.42, 95% CI: 1.01-1.99) and constipation (OR=2.11, 95% CI: 1.17-3.79). The personality subscales were not strongly linked; membership of "any" diseased cluster was associated with a reduced odds of being in the fourth quartile for the well-being scale (OR=0.64, 95% CI: 0.46-0.88) but increased odds of being in the fourth quartile for the social potency scale (OR=1.64, 95% CI: 1.18-2.28). CONCLUSIONS: In a young adult community sample, unexplained GI symptoms appear to be linked to psychiatric disorders but personality differences were minimal.     

Genitourinary health in a population‐based cohort of males with Duchenne and Becker Muscular dystrophies

Introduction: Genitourinary (GU) health among patients with Duchenne and Becker muscular dystrophies (DBMD) has not been explored using population‐based data. Methods: Medical records of 918 males ascertained by the Muscular Dystrophy Surveillance, Tracking, and Research Network were reviewed for documentation of GU‐related hospitalizations and prescribed medications. Percentages of males who received these medical interventions were calculated, and hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for associations with sociodemographics (study site, race/ethnicity), symptoms (early‐ vs. late‐onset, ambulation status, scoliosis), and treatments (respiratory support, steroids). Results: Among the 918 males, 81 (9%) had a GU condition, with voiding dysfunction (n = 40), GU tract infection (n = 19), and kidney/ureter calculus (n = 9) most frequently seen. The Kaplan‐Meier curve produced a cumulative probability of 27%. Cox regression showed GU conditions were more common when males were non‐ambulatory (HR 2.7, 95% CI 1.3–5.6). Conclusions: Our findings highlight the need for increased awareness of GU health and multidisciplinary care of DBMD patients. Muscle Nerve 52 : 22–27, 2015     

Risk of suicide attempt and suicide death in patients treated for bipolar disorder

OBJECTIVES: To evaluate demographic and clinical predictors of suicide attempt and suicide death in a population-based sample of people treated for bipolar disorder (BD). METHODS: Computerized records were used to identify 32,360 individuals treated for BD at two large prepaid health plans. Suicide attempts were identified using computerized records of outpatient visit diagnoses and hospital discharge diagnoses. Suicide deaths were identified using state death certificate data. RESULTS: Overall event rates were 1.06 per 1,000 person-years for suicide death, 5.6 per 1,000 person-years for suicide attempt leading to hospitalization, and 13.9 per 1,000 person-years for suicide attempt not leading to hospitalization. Men had a significantly lower rate of suicide attempt [hazard ratio (HR) 0.68, 95% confidence interval (CI) 0.56-0.83] but a higher rate of suicide death (HR 2.70, 95% CI 1.69-4.31). Suicide attempts were significantly more frequent among younger patients, but suicide deaths did not vary significantly by age. Substance use comorbidity was significantly related to risk of suicide attempt (HR 2.53, 95% CI 2.07-3.09) but not to risk of suicide death (HR 1.02, 95% CI 0.54-1.93). Comorbid anxiety disorder was associated with significantly higher risk of both suicide attempt (HR 1.40, 95% CI 1.14-1.72) and suicide death (HR 1.81, 95% CI 1.09-2.99). CONCLUSIONS: Among people treated for BD, risk of suicide death is significantly related to male sex and comorbid anxiety disorder. The predictors of suicide death differ markedly from predictors of suicide attempt.     

Morbidity associated with sleep disorders in primary care: a longitudinal cohort study

Objective: Few epidemiologic studies evaluate the relative contribution of different risk factors on sleep problems. The aim of the present study was to assess demographics, comorbid characteristics, and health outcomes in patients with sleep disorders.Method: A population-based cohort study with nested case-control analysis was conducted in adults using the U.K. General Practice Research Database. Information was collected for 12,437 patients with a new sleep disorder diagnosis during the year 1996 and 18,350 age- and sex-matched controls. Logistic regression analysis was used to compute odds ratios (OR) and 95% confidence intervals (CI).Results: The incidence of a new sleep disorder diagnosis was 12.5 per 1000 person-years. There was a clear association of sleep disorders with smoking and excessive alcohol consumption; prior psychiatric disorders, including stress (OR = 3.6, 95% CI = 2.9 to 4.4) and depression (OR = 3.1, 95% CI = 2.8 to 3.3); prior circulatory diseases, including heart failure (OR = 1.8, 95% CI = 1.4 to 2.2) and coronary heart disease (OR = 1.4, 95% CI = 1.2 to 1.6); and prior gastrointestinal diseases, including gastroesopha-geal reflux disease (OR = 1.4, 95% CI = 1.2 to 1.7) and irritable bowel syndrome (OR = 1.5, 95% CI = 1.2 to 1.9). Use of hypnotics and anti-depressants was increased in the year after diagnosis. Relative 1-year mortality risk was 3-fold higher in the sleep disorder group than in controls, with a noticeably higher proportion of deaths due to suicide.Conclusion: The fact that sleep disorders were associated with several morbidities, most strongly with psychiatric disorders as well as with increased mortality, underscores the importance of sleep problems as indicators of health status.     

Risk factors for suicide and other deaths following hospital treated self-poisoning in Australia

OBJECTIVE: To analyze the risk factors for suicide, premature death and all-cause death in a representative population of hospital-treated deliberate self-poisoning patients. METHOD: A prospective cohort study using data-linkage between the Hunter Area Toxicology Service Database and the National Death Index of the Australian Institute of Health and Welfare, from January 1991 to December 2000. RESULTS: There were 4105 subjects, of whom 228 (5.6%) died, 122 (2.9%) by premature death and 58 (1.4%) by suicide. The probability of suicide after 10 years follow-up was 2%. The adjusted hazard ratios (95% CI) for suicide were: 'disorders usually diagnosed in infancy, childhood and adolescence', 5.28 (95% CI = 2.04-13.65): male gender, 4.25 (95% CI = 2.21-8.14); discharge to involuntary psychiatric hospital admission, 3.20 (95% CI = 1.78-5.76); and increasing age, 1.02 (95% CI = 1.01-1.04). Men and women showed different patterns of multivariate risks, although increased risk with increasing age and discharge to an involuntary psychiatric admission was true for both. The standardized all-cause mortality ratio (95% CI) was: for men, 6.42 (95% CI = 5.44-7.57), and for women 4.39 (95% CI = 3.56-5.41). The standardized suicide mortality ratio (95% CI) was: for men, 20.55 (95% CI = 15.24-27.73), and for women 22.95 (95% CI = 13.82-38.11). CONCLUSIONS: Men and women have different risk factors for subsequent suicide after self-poisoning. Hospital-treated self-poisoning patients have increased risk of subsequent suicide, premature and all-cause death. Psychiatric assessment, leading to discharge decisions, is worthwhile in identifying patients at long-term risk of suicide, premature and all-cause death.     

Cancer mortality in patients with psychiatric diagnoses: a higher hazard of cancer death does not lead to a higher cumulative risk of dying from cancer

Purpose

Both increased as well as decreased cancer mortality among psychiatric patients has been reported, but competing death causes were not included in the analyses. This study aims to investigate whether observed cancer mortality in patients with psychiatric disorders might be biased by competing death causes.

Method

In this retrospective cohort study on data from the Psychiatric Case Register Middle Netherlands linked to the death register of Statistics Netherlands, the risk of cancer death among patients with schizophrenia (N = 4,590), bipolar disorder (N = 2,077), depression (N = 15,130) and their matched controls (N = 87,405) was analyzed using a competing risk model.

Results

Compared to controls, higher hazards of cancer death were found in patients with schizophrenia (HR = 1.61, 95 % CI 1.26–2.06), bipolar disorder (HR = 1.20, 95 % CI 0.81–1.79) and depression (HR = 1.26, 95 % CI 1.10–1.44). However, the HRs of death due to suicide and other death causes were more elevated. Consequently, among those who died, the 12-year cumulative risk of cancer death was significantly lower.

Conclusions

Our analysis shows that, compared to the general population, psychiatric patients are at higher risk of dying from cancer, provided that they survive the much more elevated risks of suicide and other death causes.     

Suboptimal depression screening following cancer diagnosis

OBJECTIVE: To describe the proportion of veterans with cancer screened for depression as compared to the general population (GenPop) of veterans. METHODS: Data were abstracted from electronic medical records (2000-2004) at a Midwestern Veterans Health Administration (VHA) facility and from the VHA External Peer Review Program (EPRP). Depression screening was assessed in the 12-month period following cancer diagnosis or in the 12-month period prior to EPRP medical record abstraction. Statistical analysis included multivariate logistic regression. RESULTS: Annual depression screening among veterans with cancer improved from 42% in 2000 to 81% in 2003. Screening was 9-31% lower and 11-50% lower among veterans with cancer at the Midwestern facility, as compared to the GenPop of veterans nationwide and at the Midwestern facility, respectively. Of subjects with cancer at the Midwestern facility, 19% screened positive. Advanced disease [odds ratio (OR)=0.51; 95% confidence interval (CI(95)): 0.38-0.68] and respiratory cancers (OR=0.55; CI(95): 0.38-0.80) were associated with lower odds of screening receipt. CONCLUSIONS: Screening for depression among veterans with cancer improved 39% but is considerably lower than the proportion of GenPop veterans screened nationally and at the local facility. Targeted interventions to improve screening in patients with cancer are required based on evidence that screening translates into increased provider recognition and treatment of depression.     

Meta-analysis of the effects of psychosocial interventions on survival time in cancer patients

OBJECTIVE: To provide a quantitative summary of effects of psychosocial interventions on cancer survival, and to present an overview of methodological and reporting aspects of the studies. METHOD: Electronic searches and manual searches of reference lists from review articles and retrieved papers. Two coders independently coded study, participant, treatment, and outcome characteristics of the studies meeting selection criteria. RESULTS: Thirteen journal articles published between 1989 and 2003 reporting results from 14 controlled intervention studies were included. Results are based on data obtained from 2626 subjects. Effect sizes [hazard ratios (HR)] were heterogeneous and random effects models were used in the analyses. The total mean inverse-variance-weighted HR was 0.85 (95% CI: 0.65-1.11). Randomized studies (n=8) showed no overall treatment effect (HR: 0.77, 95% CI: 0.56-1.06), neither did the nonrandomized studies (HR: 1.00, 95% CI: 0.61-1.62). Interventions using individual treatment (n=3) were, however, found to be effective (HR: 0.55, 95% CI: 0.43-0.70) but interventions using group treatment (n=9) were ineffective (HR: 0.97, 95% CI: 0.73-1.27). Group treatments of breast cancer (n=6) were ineffective (HR: 0.95, 95% CI: 0.69-1.31). CONCLUSION: A definite conclusion about whether psychosocial interventions prolong cancer survival seems premature. Future studies should use randomization to avoid self-selection of patients with poor prognosis. Interventions should focus on a single diagnosis, take into account known risk factors, and describe their interventions thoroughly.     

上海地区汉族人群LMTK2与MSMB基因多态性与前列腺癌的易感性

目的：探讨中国上海地区汉族人群中LMTK2与MSMB基因多态性与前列腺癌遗传易感性的关系。 方法：采用病例对照研究,提取200例前列腺癌患者(病例组)和200例非前列腺癌健康人(对照组)外周血中基因组DNA,应用ABI 3730 XL测序仪分析病例组和对照组的LMTK2基因rs6465657位点以及MSMB基因rs10993994位点的多态性,比较不同基因型与前列腺癌易感性的关系。 结果：MSMB基因rs10993994位点密码子T/C基因型的个体其前列腺癌发病风险是C/C基因型的1.62倍(OR =1.62, 95% 可信区间：1.12~2.27),携带MSMB基因rs10993994位点等位基因T(T/T,T/C)的个体发生前列腺癌的风险性是C/C基因型的0.96倍(OR =0.96, 95% 可信区间：0.82~1.11)。LMTK2基因rs6465657位点密码子C/C基因型的个体其前列腺癌发病风险与T/C基因型无明显差异。 结论：中国上海地区汉族人群中MSMB基因rs10993994位点多态性可能对前列腺癌遗传易感性有影响,而LMTK2基因rs6465657位点对前列腺癌遗传易感性无明显影响。     

The emotional toll of spousal morbidity and mortality.

OBJECTIVE: Spouse caregivers have an increased risk of mental and physical illness during caregiving and widowhood. The authors sought to evaluate whether partners of an ill spouse have a higher likelihood of developing mental health or substance abuse (MHSA) disorders than partners who have healthy spouses, accounting for both spousal illness and death. METHODS: The authors used Medicare claims from 1993-2001 for 474,228 married couples. The authors used Cox models to determine the effect of spouse illness on partner MHSA diagnosis, controlling for demographic and clinical characteristics. RESULTS: A wife's hospitalization increased the husband's risk of MHSA diagnosis by 1.29 (95% confidence interval [CI]: 1.28-1.29) and his risk of depression by 1.49 (95% CI: 1.48-1.51). A husband's hospitalization increased the risk of a wife's MHSA diagnosis by 1.33 (95% CI: 1.32-1.33) and her risk of depression by 1.41 (95% CI: 1.39-1.42). A wife's death increased the risk of the husband's MHSA diagnosis by 1.12 (95% CI: 1.11-1.13) and increased his risk of depression by 1.49 (95% CI: 1.46-1.51). A husband's death increased the risk of the wife's MHSA diagnosis by 1.14 (95% CI: 1.14-1.15) and increased her risk of depression by 1.41 (95% CI: 1.39-1.42). CONCLUSION: Spouse hospitalizations and spouse death independently increase the risk for partner MHSA and depression diagnoses. These findings can identify which individuals are at greatest risk for emotional distress and should be targeted for interventions to relieve caregiver burden that can arise separately and additively from both spousal illness and death.     

Incidence of cancer among persons with schizophrenia and their relatives

BACKGROUND: It has repeatedly been reported that the risk for cancer in patients with schizophrenia is different from that of the general population, specifically a lower risk for lung cancer despite increased smoking. Confirmation of these associations could lead to hypotheses on shared risk or protective factors, either genetic or environmental. METHODS: From Finland's National Hospital Discharge and Disability Pension registers, Helsinki, we identified a cohort of 26 996 individuals born between 1940 and 1969 and treated for schizophrenia between 1969 and 1991. They were followed up for cancer from 1971 to 1996 by record linkage with the Finnish Cancer Registry, yielding 446 653 person-years at risk, and standardized incidence ratios (SIRs) were calculated. Likewise, 39 131 parents and 52 976 siblings of the patients with schizophrenia were followed up to explore familial genetic hypotheses on deviations in cancer risk. RESULTS: In patients with schizophrenia, an increased overall cancer risk was found (724 cases observed vs 619 expected; SIR, 1.17; 95% confidence interval [CI], 1.09-1.25). Half of the excess cases were attributable to lung cancer (SIR, 2.17; 95% CI, 1.78-2.60), and the strongest relative increase in risk was in pharyngeal cancer (SIR, 2.60; 95% CI, 1.25-4.77). Cancer incidence in siblings (SIR, 0.89; 95% CI, 0.83-0.94) and parents (SIR, 0.91; 95% CI, 0.89-0.93) was consistently lower than that in the general population. CONCLUSION: Although specific lifestyle factors, particularly tobacco smoking and alcohol consumption, probably account for the increased cancer risk in patients with schizophrenia, the decreased risk in relatives would be compatible with a postulated genetic risk factor for schizophrenia offering selective advantage to unaffected relatives.     

Demographic, family, and occupational characteristics associated with major depression: the Harvard study of moods and cycles

OBJECTIVE: This study assesses the extent to which women with and without major depression differ by demographic, familial, and occupational characteristics. METHOD: From a community-based sample, the authors identified 332 women with and 644 women without current or past major depression based on Structured Clinical Interviews for DSM-IV. Demographic and background interviews were conducted in-person. RESULTS: Depressed women were more likely to have gained >or =35 lbs between age 18 and study enrollment (OR=1.6, 95% CI 1.1-2.5), experienced divorce (OR=2.0, 95% CI 1.4-2.8), or changed occupations (OR=1.5, 95% CI 1.1-2.1) compared with non-depressed women. Compared with women with no brothers, those with > or =1 brothers were less likely to have a history of depression (OR=0.8, 95% CI 0.6-1.1), whereas compared with women with no sisters, those with > or =1 sisters were more likely to have current or past depression (OR=1.4, 95% CI 1.0-1.9). These findings were not influenced by family sibship size. CONCLUSION: These results illustrate demographic differences between women with and without major depression and that sibship gender rather than size may also influence risk.     

Increased incidence of affective disorders, anxiety disorders, and non-natural mortality in women after breast cancer diagnosis: a nation-wide cohort study in Denmark

OBJECTIVE: To investigate whether breast cancer patients have increased incidence of psychiatric admission with affective disorders, anxiety disorders, or non-natural mortality compared with the general female population. METHOD: Register-linkage between nation-wide registries: The Danish Psychiatric Central Register, The Danish Cancer Registry, and The Danish National Register of Causes of Death. A total of 61 709 women registered with primary invasive breast cancer between 1970 and 1993 were included and 356 023 person-years were accrued. RESULTS: The standardized incidence ratio of first-ever psychiatric admission with affective disorder was 1.49 (95% CI: 1.35-1.63) and with anxiety disorder 1.25 (95% CI: 1.06-1.46). The standardized non-natural mortality ratio during the first year after breast cancer diagnosis was 1.54 (95% CI: 1.27-1.87). All analyses were adjusted for age, calendar period, and place of residence. CONCLUSION: Breast cancer patients have significantly increased incidence of psychiatric admission with affective disorders, anxiety disorders, and non-natural mortality.

Social support and suicide in Japanese men and women - the Japan Public Health Center (JPHC)-based prospective study

Although the important role of social support in mental health is acknowledged, no prospective study has yet examined the relation of social support to suicide. Here, we investigated the association between social support and suicide in a cohort of Japanese men and women. A total of 26,672 men and 29,865 women aged 40–69 years enrolled in the Japan Public Health Center-based prospective study in 1993–1994 completed a self-administered questionnaire which included four items of social support, and were followed for death through December 2005. Hazard ratios (HRs) and 95% confidence intervals (95% CI) of suicidal death by social support index were estimated using a Cox proportional hazards regression model. A total of 180 suicidal deaths were recorded during an average of 12 years’ follow-up. Men and women with the highest level of social support had a significantly decreased risk of suicide, with HRs (95% CI) for the highest versus lowest social support group of 0.56 (0.33–0.94) and 0.38 (0.16–0.89) in men and women, respectively. Esteem support and having four or more friends were associated with a lower risk of suicide in women [0.32 (0.13–0.77)] and in both sexes [men: 0.56 (0.36–0.88); women: 0.65 (0.32–1.30)], respectively, whereas confident support was not. These findings suggest that social support may be important for suicide prevention. Avoiding social isolation may decrease the incidence of suicide in men and women, and esteem support can provide additional benefit for women.     

Major depression in individuals with chronic medical disorders: prevalence, correlates and association with health resource utilization, lost productivity and functional disability

OBJECTIVE: The objective of this study was to determine the prevalence and odds of major depression and the incremental effect of major depression on utilization, lost productivity and functional disability in individuals with common chronic medical disorders. METHOD: Data on 30,801 adults from the 1999 National Health Interview Survey were analyzed. The 12-month prevalence and age/sex-adjusted odds of major depression were calculated for adults with hypertension (HTN), diabetes mellitus (DM), coronary artery disease (CAD), congestive heart failure (CHF), stroke or cerebrovascular accident (CVA), chronic obstructive pulmonary disease (COPD) and end-stage renal disease (ESRD). The association between chronic condition status (with and without major depression) and utilization, lost productivity and functional disability was determined by controlling for covariates. RESULTS: The 12-month prevalence and age/sex-adjusted odds of major depression by chronic conditions were as follows: CHF, 7.9% [odds ratio (OR)=1.96]; HTN, 8.0% (OR=2.00); DM, 9.3% (OR=1.96); CAD, 9.3% (OR=2.30); CVA, 11.4% (OR=3.15); COPD, 15.4% (OR=3.21); ESRD, 17.0% (OR=3.56); any chronic condition, 8.8% (OR=2.61). Compared to adults without chronic conditions, those with chronic conditions plus major depression had greater odds of > or = 1 ambulatory visit [OR=1.50; 95% confidence interval (95% CI)=1.28, 1.77]; > or = 1 emergency room visit (OR=1.94; 95% CI=1.55, 2.45); and > or = 1 day in bed due to illness (OR=1.60; 95% CI=1.28, 2.00); and functional disability (OR=2.48; 95% CI=1.96, 3.15). CONCLUSION: The 12-month prevalence and odds of major depression are high in individuals with chronic medical conditions, and major depression is associated with significant increases in utilization, lost productivity and functional disability.
