Gender differences in the association between depressive mood and mortality: a 12-year follow-up population-based study

Depressive Symptoms, Socioeconomic Position, and Mortality in Older People Living With and Beyond Cancer

OBJECTIVE

Evidence shows that higher depressive symptoms are associated with mortality among people living with and beyond cancer (LWBC). However, prior studies have not accounted for a wider range of potential confounders, and no study has explored whether socioeconomic position (SEP) moderates the association. This study aimed to examine the association between depressive symptoms and mortality among people LWBC, and moderation by SEP.

METHODS

Participants from the English Longitudinal Study of Aging, diagnosed with cancer and with a measure of depressive symptoms within 4 years after their diagnosis, were included. Elevated depressive symptoms were indicated by a score of ≥3 on the eight-item Center for Epidemiologic Studies Depression Scale. Cox regression models examined associations with all-cause mortality. Competing risk regression examined associations with cancer mortality.

RESULTS

In 1352 people LWBC (mean age = 69.6 years), elevated depressive symptoms were associated with a 93% increased risk of all-cause mortality (95% confidence interval = 1.52-2.45) within the first 4 years of follow-up and a 48% increased risk within a 4- to 8-year follow-up (95% confidence interval = 1.02-2.13) after multivariable adjustment. Elevated depressive symptoms were associated with a 38% increased risk of cancer mortality, but not after excluding people who died within 1 year after baseline assessments. There were no interactions between depressive symptoms and SEP.

CONCLUSIONS

Elevated depressive symptoms are associated with a greater risk of all-cause mortality among people LWBC within an 8-year follow-up period. Associations between depressive symptoms and cancer mortality might be due to reverse causality.

Re-engagement of Early Adolescents with Severe School Issues in School/Professional Project Reduces School-Behavior-Health Problems

BACKGROUND

In France, 3.2 million middle-school students have serious/persistent school difficulties and are re-engaged in adapted-general/vocational-education class (AGVEC), created to early re-engage them in school/professional projects. We assessed the AGVEC's benefits for school-behavior-health-related difficulties (SBHDs).

METHODS

This population-based study compared 83 AGVEC students (mean age = 14.4 ± 1.1) with 1559 regular-class students (mean age = 13.5 ± 1.3) from north-eastern France. They completed a questionnaire collecting socioeconomic features and SBHDs. The data were analyzed using logistic regression models and Kaplan-Meier estimates.

RESULTS

The AGVEC students had similar academic performance but fewer school absences due to health problems, less sleep difficulty, fewer depressive symptoms, and more social support as compared with regular-class students: sex-age-class-level-adjusted odds ratio (saclOR) 0.31-0.56 (p < 0.05/0.001). The AGVEC students had fewer skipping school, better health status, less sleep difficulty, fewer depressive symptoms, fewer suicide ideation/attempt, and more social support as compared with regular-class students with low academic performance: saclOR 0.22-0.52 (most with p < 0.01). Socioeconomic features played modest roles. The benefits for depressive symptoms and suicide attempt increased with age since age 10.

CONCLUSIONS

Re-engagement in the AGVEC is particularly effective in reducing SBHDs.

Cancer mortality in Common Mental Disorders: A 10-year retrospective cohort study

PURPOSE

Individuals with Common Mental Disorders (CMDs) may have a higher cancer mortality. The purpose of this study was to examine cancer-related mortality among patients with CMDs and verify which cancer types are predominantly involved.

METHODS

We used the Regional Mental Health Registry of the Emilia-Romagna region, in Northern Italy to identify patients aged ≥ 18 years who received an ICD 9-CM diagnosis of CMDs (i.e., depressive and neurotic disorders) over a 10 year period (2008-2017). Information on cause of death was retrieved from the Regional Cause of Death Registry. Comparisons were made with data from the regional population without CMDs.

RESULTS

Among 101,487 patients suffering from CMDs (55.7% depression; 44.3% neurotic disorders), 3,087 (37.8%) died from neoplasms. The total standardized mortality ratio (SMR) was 1.82 (95% CI 1.78-1.86) while the SMR for all neoplasms was 2.08 (95% CI 2.01-2.16). Individuals of both genders, with both depressive and neurotic disorders had a higher risk of death from almost all cancers compared with the regional population.

CONCLUSION

Patients with CMDs have considerably higher cancer mortality risk than the general population. Higher mortality was observed for a broad range of cancers associated with different aetiologies. It is imperative to promote cancer awareness, prevention and treatment for people with CMDs.

Association of ECT With Risks of All-Cause Mortality and Suicide in Older Medicare Patients

OBJECTIVE

This observational study examined the effects of electroconvulsive therapy (ECT) on suicide and all-cause mortality risk in older psychiatric patients.

METHODS

Participants were Medicare-insured psychiatric inpatients age 65 or older. Patients receiving ECT were exact-matched to control subjects (in a 1:3 ratio) on age, gender, principal hospital diagnosis, past-year psychiatric hospitalizations, past-year suicide attempts, and Elixhauser comorbidity index. Cox proportional hazard models were risk-adjusted for race, year of hospitalization, rural-urban continuum code, year of index hospitalization, median income of zip code, and all matched covariates to estimate hazard ratios with 95% confidence intervals.

RESULTS

A total of 10,460 patients in the ECT group and 31,160 in the control group were included in the analyses (total N=41,620; 65.4% female; mean age, 74.7 years [SD=7.09]). Compared with the control group, patients receiving ECT had lower all-cause mortality for up to 1 year following hospital discharge (adjusted hazard ratio=0.61, 95% CI=0.56, 0.66). For death by suicide, 1-year survival analysis showed no group difference. A significant association was observed with suicide in the first months following ECT, but this pattern waned over time (1 month: hazard ratio=0.44, 95% CI=0.21, 0.91; 2 months: hazard ratio=0.52, 95% CI=0.29, 0.92; 3 months: hazard ratio=0.56, 95% CI=0.37, 0.92; 6 months: 0.87, 95% CI=0.59, 1.28; 12 months: 0.92, 95% CI=0.68, 1.25).

CONCLUSIONS

In this observational study, ECT was associated with lower 1-year all-cause mortality and with short-lived protective effects on suicide risk. These findings support greater consideration of ECT for inpatients with mood disorders at short-term risk of suicide.

Depression in dialysis

PURPOSE OF REVIEW

The aim of this study was to examine updated prevalence rates, risk factors and the prognosis, diagnosis and treatments for depression among dialysis patients.

RECENT FINDINGS

Depression influences prognosis, complications, quality of life (QOL), treatment and costs for dialysis patients worldwide. Reported prevalence of depression is 13.1-76.3%; it is higher for dialysis than transplant and higher post than predialysis. Reported depression rates with peritoneal dialysis (PD) compared with in-centre haemodialysis (HD) are inconsistent. Related medical factors are known, but suspected associated patient characteristics including gender and race remain unexplored. Associations between depression in dialysis and QOL, mortality, pathophysiological mechanisms of increased mortality, infection and pathways of inflammation-mediated and psychosocial factors require clarification. Several depression screening instruments are validated for dialysis patients - the Structured Clinical Interview for DSM disorders (SCID) remains the gold standard - but authors suggest the diagnostic standard should be higher than for the general population. Short-term studies indicate nonpharmacological therapy achieves clinical effects for depression in dialysis patients, but research on long-term effects is needed.

SUMMARY

Depression management through early screening and continuous care models emphasizing dynamic relationships between healthcare teams, patients and families should be encouraged. Large-scale studies of short-term and long-term benefits of pharmacological and nonpharmacological depression management are warranted.

Psychiatric problems of anxiety and depression disorder are associated with medical service utilization and survival among patients with cervical cancer

OBJECTIVE

There are few nationwide studies regarding the long-term analysis of cervical cancer patients in Taiwan. Thus, this study aimed to evaluate medical service utilization, and survival among cervical cancer patients initially diagnosed with or without anxiety and/or depressive disorders.

MATERIALS AND METHODS

This was a retrospective longitudinal study using data from the National Health Insurance Research Database from 1996 to 2010. The study subjects were cervical cancer patients identified by ICD-9-CM codes 180.X, while subjects with anxiety and/or depressive disorders were identified using the following codes: 300.0X-300.9X (minus 300.4X) for anxiety disorder, and 296.2X, 296.3X, 300.4, and 311.X for depressive disorder. The cervical patients with anxiety or/and depression disorder were classified as anxiety/depression (AD) group or the non-disorder (ND) group. Propensity score matching (PSM) was used to adjust for differences between the AD and ND groups. T-tests were used to evaluate differences in medical utilization and the Kaplan-Meier method was used to evaluate survival conditions between the two groups. Statistical analyses were performed using SPSS Statistics 20.0.

RESULTS

A total of 3664 patients were identified, with 862 (23.5%) having anxiety, 149 (4.1%) with depression, and 349 (9.5%) having both anxiety and depression. In total, 1360 cervical cancer patients had anxiety/depression disorders. After PSM, the AD group had significantly more outpatient department (OPD) visits than the ND group (p < 0.001) but the survival status was better in the AD group than the ND group (p < 0.001).

CONCLUSIONS

Cervical cancer patients with anxiety/depression disorders visited the OPD more frequently than those without anxiety/depression disorders but had better survival status. Gynecologists should also consider cancer patients' mental status during follow-up, referring patients to psychiatric professionals for appropriate psychiatric care if appropriate.

Depression and anxiety in relation to cancer incidence and mortality: a systematic review and meta-analysis of cohort studies

The link between depression and anxiety status and cancer outcomes has been well-documented but remains unclear. We comprehensively quantified the association between depression and anxiety defined by symptom scales or clinical diagnosis and the risk of cancer incidence, cancer-specific mortality, and all-cause mortality in cancer patients. Pooled estimates of the relative risks (RRs) for cancer incidence and mortality were performed in a meta-analysis by random effects or fixed effects models as appropriate. Associations were tested in subgroups stratified by different study and participant characteristics. Fifty-one eligible cohort studies involving 2,611,907 participants with a mean follow-up period of 10.3 years were identified. Overall, depression and anxiety were associated with a significantly increased risk of cancer incidence (adjusted RR: 1.13, 95% CI: 1.06-1.19), cancer-specific mortality (1.21, 1.16-1.26), and all-cause mortality in cancer patients (1.24, 1.13-1.35). The estimated absolute risk increases (ARIs) associated with depression and anxiety were 34.3 events/100,000 person years (15.8-50.2) for cancer incidence and 28.2 events/100,000 person years (21.5-34.9) for cancer-specific mortality. Subgroup analyses demonstrated that clinically diagnosed depression and anxiety were related to higher cancer incidence, poorer cancer survival, and higher cancer-specific mortality. Psychological distress (symptoms of depression and anxiety) was related to higher cancer-specific mortality and poorer cancer survival but not to increased cancer incidence. Site-specific analyses indicated that overall, depression and anxiety were associated with an increased incidence risks for cancers of the lung, oral cavity, prostate and skin, a higher cancer-specific mortality risk for cancers of the lung, bladder, breast, colorectum, hematopoietic system, kidney and prostate, and an increased all-cause mortality risk in lung cancer patients. These analyses suggest that depression and anxiety may have an etiologic role and prognostic impact on cancer, although there is potential reverse causality; Furthermore, there was substantial heterogeneity among the included studies, and the results should be interpreted with caution. Early detection and effective intervention of depression and anxiety in cancer patients and the general population have public health and clinical importance.

Identification of psychiatric patients with high mortality and low medical utilization: a population-based propensity score-matched analysis

Background

The decreased life expectancy and care costs of mental disorders could be enormous. However, research that compares mortality and utilization concurrently across the major category of mental disorders is absent. This study investigated all-cause mortality and medical utilization among patients with and without mental disorders, with an emphasis on identifying the psychiatric category of high mortality and low medical utilization.

Methods

A total of 570,250 individuals identified from the 2002–2013 Taiwan National Health Insurance Reearch Database consistuted 285,125 psychiatric patients and 285,125 non-psychiatric peers through 1:1 dual propensity score matching (PSM). The expenditure survival ratio (ESR) was proposed to indicate potential utilization shortage. The category of mental disorders and 13 covariates were analyzed using the Cox proportional hazard model and general linear model (GLM) through SAS 9.4.

Results

PSM analyses indicated that mortality and total medical expenditures per capita were both significantly higher in psychiatric patients than those in non-psychiatric patients (all P <.0.0001). Patients with substance use disorders were reported having the youngest ages at diagnosis and at death, with the highest 25.64 of potential years of life loss (YPLL) and relevant 2904.89 of ESR. Adjusted Cox model and GLM results indicated that, compared with anxiety disorders, affective disorders and substance use disorders were significantly associated with higher mortality (HR = 1.246 and 1.064, respectively; all P < 0.05); schizophrenia was significantly associated with higher total medical expenditures per capita (P < 0.0001). Thirteen additional factors were significantly associated with mortality or utilization (all P < 0.05).

Conclusion

Substance use disorders are the category of highest YPLL but notably in insufficient utilization. Health care utilization in patients with substance use disorders should be augmented timely after the diagnosis, especially toward home and community care. The factors related to mortality and utilization identified by this study merit clinical attention.

Handgrip strength, depression, and all-cause mortality in Korean older adults

Background

Decreased muscle strength and/or depression with aging are emerging as important public health concerns in both developed and developing countries. This study investigated the effects of low handgrip strength (HGS) and depression on the risk of all-cause mortality in Korean older adults.

Methods

Data from 13,901 Korean adults (57% women) who participated in the 2008 baseline survey and completed the 2011 follow-up assessments were used.

Results

In total, the current findings showed that individuals with depression only and individuals with low HGS plus depression had significantly higher risks of all-cause mortality (hazard ratio (HR) = 1.366, 95% confidence interval (CI) = 1.033–1.807, p = 0.029 and HR = 1.961, 95% CI = 1.409–2.736, p < 0.001, respectively) even after adjustments for all the measured covariates, compared with individuals with high HGS plus no depression (HR = 1). Gender-stratified analysis showed that men with depression only and men with depression plus low HGS had significantly higher risks of all-cause mortality (HR = 1.376, 95% CI =1.029–1.841, p = 0.031 and HR = 1.861, 95% CI = 1.306–2.651, p = 0.001, respectively) even after adjustments for all the measured covariates, compared with individuals with no depression plus high HGS (HR = 1). In women, however, the joint effect of depression and low HGS only remained significant at borderline (HR = 2.603, 95% CI = 0.981–6.908, p = 0.055) when adjusted for all the confounders.

Conclusion

The current finding suggested that depression and low HGS were significantly and synergistically associated with the increased risk of premature death from all causes in the Korean geriatric population.

Assessment of participation biases for a confidential non-anonymous adolescent study: A based population study

A prospective study often receives a low participation rate that may alter the results quality. This study assessed the participation bias for a confidential non-anonymous adolescent survey among 1559 middle-school adolescents from north-eastern France (mean age 13.5 ± 1.3). They completed an anonymous questionnaire gathering demographic/socioeconomic features as well as school, behavior and health-related difficulties, and adolescent's assent to participate with perceived parents' consent (APC) if they were contacted for a confidential non-anonymous survey at home. Such a survey received an APC of 60%. The logistic model including all socioeconomic factors and school, behavior and health-related difficulties showed that the adolescents with APC were less often male (adjusted odds ratio = 0.77, p = 0.014), non-European immigrant (0.48, p = 0.016), living with a single parent (0.72, p = 0.046), in manual-worker families (0.69, p = 0.007), had less often low parents' education (0.70, p = 0.002), body-mass-index measurement refusal (0.60, p = 0.010), no regular physical/sports activity (0.70, p = 0.035), poor social relationships (0.73, p = 0.046) and poor living environment (0.63, p = 0.007). The percentage of subjects with APC steadily decreased with the number of these criteria: from 74% for 0 criterion to 19% for 6-8 criteria. Because of these possible strong participation biases the construction of adolescent cohorts and the results interpretation should be made with prudence.

Asthma and allergy as risk factors for suicidal behavior among young adults

An association between allergic disease, depression and suicidality has been reported.

OBJECTIVE

To explore the relationships between suicidality and asthma, allergy, internet addiction, stress, sleep quality, pain/discomfort, and depression, among emerging adults.

PARTICIPANTS

929 college students completed an online survey between October 2015 and April 2017.

METHODS

A cross-sectional study using multivariate analysis techniques was implemented.

RESULTS

Using structural equation modeling, we found that allergies and stress were directly related to pain/discomfort; pain/discomfort was associated to poor sleep, depression, and suicidality. Sleep quality was also affected by stress; while sleep, stress, pain/discomfort, and internet addiction were directly related to depression (all p < .05). Ultimately, four factors impacted suicidality: stress, pain/discomfort, depression, and, indirectly, sleep quality (all p < .05). Although allergy had some effects, these did not reach statistical significance (p < .09).

CONCLUSION

Findings suggest that allergy might impact suicidality indirectly through increased pain/discomfort, poor sleep, and depression.

Perceived stress, sex and occupational status interact to increase the risk of future high blood pressure: the IPC cohort study

BACKGROUND

Contrary to lay beliefs, current perceived stress is not consistently associated with the incidence of high blood pressure (BP) in prospective studies, possibly because of moderating factors. The present prospective study examined this association and explored the potential moderating effects of sex or occupational status.

METHOD

The 4-item Perceived Stress Scale was filled at baseline by 19 766 normotensive adults (13 652 men, mean age ± SD: 46.8 ± 9.3 years), without history of cardiovascular and renal disease, and not on either psychotropic or antihypertensive drugs.

RESULTS

After a mean follow-up of 5.8 ± 2.1 years, 3774 participants (19.1%) had high BP, defined as having a SBP at least 140 mmHg or a DBP at least 90 mmHg, or using antihypertensive drugs. There was a significant interaction between baseline-perceived stress and sex (P = 0.02) in relation to high BP at follow-up. After adjustment for potential confounders, baseline perceived stress was associated with high BP at follow-up in women [odds ratio 1.20, 95% confidence interval 1.03-1.38, P = 0.016). In addition, the interaction between perceived stress and occupational status was significant among women (P = 0.02). Baseline-perceived stress was positively associated with high BP at follow-up among women of medium or low occupational status, with odds ratio suggesting a linear increase of the risk (P = 0.005).

CONCLUSION

Perceived stress may be considered as a risk factor for hypertension in women of lower occupational status. Research addressing the relationships between stress and high BP should systematically look for possible interactions with sex and occupational status.

The relationship between stroke and quality of life in Korean adults: based on the 2010 Korean community health survey

[Purpose] The purpose of this study was to investigate the status of stroke in the Republic of Korea and its relationship with QOL based on standardized data. [Subjects and Methods] This study utilized raw data from the 2010 KCHS. In total, 229,229 individuals participated in the 2010 survey. The final analysis identified 4,604 individuals who had been diagnosed by a doctor with stroke. To identify the correlation between the aftereffect-related characteristics of stroke patients and QOL, a multiple linear regression analysis was performed. [Results] Participants experiencing aftereffects had a statistically significantly lower QOL than participants who had not experienced aftereffects. Regarding the types of aftereffects, participants experiencing palsy in the arms and legs, facial palsy, communication disabilities, swallowing or eating disabilities, and visual disabilities had a statistically significantly lower QOL than participants without aftereffects. The QOL of participants with one, two, three, four, or five aftereffects was statistically significantly less than that of participants without aftereffects [Conclusion] Stroke directly influences QOL and the number of types of aftereffects experienced by patients. Therefore, it is highly important that physical therapists seek to end the occurrence of one or more types of aftereffects in stroke patients.

Anhedonic depression, history of depression, and anxiety as gender-specific risk factors of myocardial infarction in healthy men and women: The HUNT study

This prospective study examines gender-specific psychological risk factors of myocardial infarction. Out of 41,248 participants free of coronary heart disease at baseline, 822 cases of myocardial infarction were identified in the Nord-Trøndelag Health Study or the mortality register. The participants completed the Hospital Anxiety and Depression Scale. Cholesterol, blood pressure, and waist–hip ratio were measured by medical staff. Smoking, diabetes, non-fatal myocardial infarction, and history of depressive episode were self-reported. Anhedonic depression (Hospital Anxiety and Depression Scale-D ≥8) was a significant predictor of myocardial infarction in women but not in men. Gender difference in risk estimate based on Hospital Anxiety and Depression Scale-D was significant (p < .01). History of depressive episode was a significant predictor of myocardial infarction in men. Symptoms of anxiety (Hospital Anxiety and Depression Scale-A ≥8) reduced the risk of having a myocardial infarction.

Gender and family disparities in suicide attempt and role of socioeconomic, school, and health-related difficulties in early adolescence

Suicide attempt (SA) is common in early adolescence and the risk may differ between boys and girls in nonintact families partly because of socioeconomic, school, and health-related difficulties. This study explored the gender and family disparities and the role of these covariates. Questionnaires were completed by 1,559 middle-school adolescents from north-eastern France including sex, age, socioeconomic factors (family structure, nationality, parents' education, father's occupation, family income, and social support), grade repetition, depressive symptoms, sustained violence, sexual abuse, unhealthy behaviors (tobacco/alcohol/cannabis/hard drug use), SA, and their first occurrence over adolescent's life course. Data were analyzed using Cox regression models. SA affected 12.5% of girls and 7.2% of boys (P < 0.001). The girls living with parents divorced/separated, in reconstructed families, and with single parents had a 3-fold higher SA risk than those living in intact families. Over 63% of the risk was explained by socioeconomic, school, and health-related difficulties. No family disparities were observed among boys. Girls had a 1.74-time higher SA risk than boys, and 45% of the risk was explained by socioeconomic, school, and mental difficulties and violence. SA prevention should be performed in early adolescence and consider gender and family differences and the role of socioeconomic, school, and health-related difficulties.

Associations between quality of life and socioeconomic factors, functional impairments and dissatisfaction with received information and home-care services among survivors living at home two years after stroke onset

Background

Quality of life (QoL) assessment is important when monitoring over time the recovery of stroke-survivors living at home. This study explores the associations between QoL and socioeconomic factors, functional impairments and self-reported dissatisfaction with received information and home-care services among survivors two years after stroke onset. This problem remains partially addressed though optimal information and services may improve survivors’ QoL.

Methods

Stroke-survivors admitted to all hospitals in Luxembourg 18 months or more previously were identified using the only care-expenditure-reimbursement national system database. The clinical diagnosis was confirmed. Ninety four patients aged 65 years and living at home were interviewed to gather socioeconomic characteristics, functional impairments, dissatisfaction with information and home-care services, and QoL (using the Newcastle Stroke-Specific QoL, newsqol) assessing 11 domains. Data were analyzed using multiple linear regression models.

Results

About 50% of survivors had low education and lower income. Functional impairments were common: sensory (45%), motor (35%), memory (32%), language (31%), and vision (20%). Survivors with education (<12th grade) or lower income had low values for most newsqol domains (sex-age-adjusted regression coefficient saRC, i.e. mean difference, between -23 and -8). Patients who were working had better values for pain, mental feelings and sleep domains than did retired people (saRC between -3.9 and 4.2). Various functional impairments were associated with markedly low values of nearly all domains (saRC between -33.5 and -7.5) and motor, language, memory and sensory impairments had the highest impact. The survivors’ perceived QoL was markedly low, especially for the domains of interpersonal relationship, sleep, cognition, mental feelings, and pain. Various QoL domains were strongly related to dissatisfaction with information about stroke and its consequences/changes over time, accuracy of information obtained, help received, coordination between services, and the possibility of receiving help when necessary (saRC reaching -30).

Conclusions

Stroke-survivors had major alterations in QoL that reflected depressive symptoms, which should be appropriately treated. These findings may help with the development of public policies aiming at improving QoL among stroke survivors. The newsqol could be used routinely to measure the recovery of survivors over time and their needs in terms of information, help and care services.

Depression and the risk of cancer: a 15-year follow-up study of the GAZEL cohort

Depression has long been hypothesized to be associated with cancer incidence. However, there is evidence for a positive publication bias in this field. In the present study, we examined the association between various measures of depression and cancer incidence at several sites. A total of 14,203 members of the French GAZEL (Gaz et Electricité) cohort (10,506 men, 3,697 women) were followed up for diagnoses of primary cancers from January 1, 1994, to December 31, 2009. All medically certified sickness absences for depression recorded between January 1, 1990, and December 31, 1993, were compiled. Depressive symptoms were self-reported in 1993, 1996, and 1999 with the Center for Epidemiologic Studies Depression Scale. During a mean follow-up period of 15.2 years, 1,119 participants received a cancer diagnosis, excluding nonmelanoma skin cancer and in situ neoplasms. Considering 6 cancer sites (prostate, breast, colorectal, smoking-related, lymphoid and hematopoietic tissues, other sites) and 4 measures of depression, we found 1 positive association and 1 negative association. Overall, there was no compelling evidence for an association between depression and cancer incidence. Such null results should be considered when addressing concerns of cancer patients and their relatives about the role of depression in cancer onset.

Mortality gradient across the labour market core-periphery structure: a 13-year mortality follow-up study in north-eastern France

PURPOSE

This study explores mortality related to temporary employment, about which very little is known to date.

METHODS

In 1996, a health survey was carried out in the French region of Lorraine, and all members of 8,000 randomly chosen households were followed up for mortality over a 13-year period. Mortality of subjects in relation to their employment situation at baseline was analysed using a Cox survival regression.

RESULTS

In comparison with permanent workers, for unemployed men, we found age and occupation-adjusted hazard ratios (HR) of 4.1 for all-causes of death and 3.9 for non-violent causes, and for male temporary workers a HR of 2.2 for both all-causes and non-violent causes of death. Bad health, tobacco smoking and alcohol misuse explained 17 % of the excess risk for the unemployed and 41 % of that for temporary workers.

CONCLUSION

The observation of large mortality inequalities across the labour market core-periphery structure has important policy implications, particularly in terms of prevention focused on unhealthy behaviours among male unemployed and temporary workers.

Socioeconomic inequities patterns of multi-morbidity in early adolescence

BACKGROUND

Multi-morbidity such as cumulating mental health, behavioral, and school difficulties (consumptions of alcohol, tobacco, cannabis, and hard drugs, obesity, depressive symptoms, suicide attempts, involvement in violence, and low school performance) is common in early adolescence and can be favored by a number of socioeconomic factors (gender, age, nationality, family structure, parents' education, father' occupation, and income). This study assessed the concurrent roles of various socioeconomic factors in multi-morbidity defined as cumulated number of difficulties (CD) which has been partially documented.

METHODS

Adolescents from middle schools in north-eastern France (N = 1,559) completed a questionnaire measuring socioeconomic characteristics and mental health, behavioral, and school difficulties. Data were analyzed using logistic regression models.

RESULTS

Alcohol use affected 35.2% of subjects, tobacco use 11.2%, cannabis use 5.6%, hard drugs use 2.8%, obesity 10.6%, depressive symptoms 13.3%, suicide attempts 9.9%, involvement in violence 10.3%, and low school performance 8.2%. Insufficient income and non-intact families impacted most mental health, behavioral, and school difficulties with adjusted odds ratios (ORa) between 1.51 and 3.72. Being immigrant impacted illicit drugs use and low school performance (ORa 2.31-4.14); low parents' education depressive symptoms (1.42) and school performance (3.32); and manual-worker/inactive offspring low school performance (2.56-3.05). Multi-morbidity was very common: CD0 44.1%, CD1 30.8%, CD2-3 18.4%, and CD ≥ 4 6.7%. Insufficient income, divorced/separated parents, reconstructed families, and single parents played impressive roles with strong ORa gradients (reaching 4.86) from CD1 to CD ≥ 4. Being European immigrant, low parents' education, and low fathers' occupations had significant gender-age-adjusted odds ratios for CD2-3 and CD ≥ 4, but these became non-significant when adjusted for all socioeconomic factors. Older adolescents had higher risks for multi-morbidity which did not change when adjusting for all socioeconomic factors.

CONCLUSIONS

Multi-morbidity including a wide range of mental health, behavioral, and school difficulties was common in early adolescence. Insufficient income and non-intact families played impressive roles. Being immigrant, low parents' education, and low fathers' occupations also played strong roles but these were explained by insufficient income and non-intact families. Prevention against multi-morbidity should be designed to help adolescents to solve their difficulties, especially among adolescents with socioeconomic difficulties.

Mortality associated with depression as compared with other severe mental disorders: a 20-year follow-up study of the GAZEL cohort

Individuals with severe mental disorders (SMD) have an increased risk of mortality from somatic diseases. This study examined whether this risk is different in persons with depressive disorders compared to those with other SMD (i.e. schizophrenia and bipolar disorder). In 1989, 20,625 employees of the French national gas and electricity company (15,011 men and 5614 women, aged 35-50) agreed to participate in the GAZEL cohort study. Three diagnosis groups were created based on sick leave spells from 1978 onwards: 1) no SMD, 2) depressive disorders and 3) other SMD. Dates and causes of death were available from January 1, 1990 to December 31, 2010. The association of diagnosis groups with mortality was estimated with hazard ratios (HR) and 95% confidence intervals (CI) computed using Cox regression. During a mean follow-up of 19.8 years, 1544 participants died, including 1343 from a natural cause, of which 258 died from cardiovascular diseases. After adjustment for age, gender, occupational status, alcohol consumption, smoking and body-mass index, participants with a history of sickness absence for SMD had a greater risk of natural mortality (HR: 1.24, CI: 1.08-1.43), cardiovascular mortality (HR: 1.49, CI: 1.08-2.05) and non-cardiovascular natural mortality (HR: 1.19, CI: 1.02-1.39). Compared to depressive disorders, other SMD were associated with an increased risk of natural mortality (HR: 1.94, CI: 1.17-3.22) and cardiovascular mortality (HR: 3.58, CI: 1.53-8.39). Job security and systematic medical follow-up may fall short of preventing premature death among workers with sickness absence due to SMD.
