A Swedish national twin study of lifetime major depression.

Abstract: OBJECTIVE: Substantial evidence supports the heritability of lifetime major depression. Less clear is whether genetic influences in major depression are more important in women than in men and whether genetic risk factors are the same in the two sexes. It is not known whether genetic effects on major depression are constant across historical cohorts. METHOD: Lifetime major depression was assessed at personal interview by modified DSM-IV criteria in 42,161 twins, including 15,493 complete pairs, from the national Swedish Twin Registry. Twin models were evaluated by using the program Mx. RESULTS: Model fitting indicated that the heritability of liability to major depression was significantly higher in women (42%) than men (29%) and the genetic risk factors for major depression were moderately correlated in men and women. No significant differences were seen in the etiologic roles of genetic and environmental factors in major depression in three cohorts spanning birth years 1900–1958. CONCLUSIONS: In the lar...

The health and productivity cost burden of the "top 10" physical and mental health conditions affecting six large U.S. employers in 1999.

Abstract: A multi-employer database that links medical, prescription drug, absence, and short term disability data at the patient level was analyzed to uncover the most costly physical and mental health conditions affecting American businesses. A unique methodology was developed involving the creation of patient episodes of care that incorporated employee productivity measures of absence and disability. Data for 374,799 employees from six large employers were analyzed. Absence and disability losses constituted 29% of the total health and productivity related expenditures for physical health conditions, and 47% for all of the mental health conditions examined. The top-10 most costly physical health conditions were: angina pectoris; essential hypertension; diabetes mellitus; mechanical low back pain; acute myocardial infarction; chronic obstructive pulmonary disease; back disorders not specified as low back; trauma to spine and spinal cord; sinusitis; and diseases of the ear, nose and throat or mastoid process. The most costly mental health disorders were: bipolar disorder, chronic maintenance; depression; depressive episode in bipolar disease; neurotic, personality and non-psychotic disorders; alcoholism;, anxiety disorders; schizophrenia, acute phase; bipolar disorders, severe mania; nonspecific neurotic, personality and non-psychotic disorders; and psychoses. Implications for employers and health plans in examining the health and productivity consequences of common health conditions are discussed.

Severe mental illness in 33,588 prisoners worldwide: systematic review and meta-regression analysis.

Abstract: Background High levels of psychiatric morbidity in prisoners have been documented in many countries, but it is not known whether rates of mental illness have been increasing over time or whether the prevalence differs between low–middle-income countries compared with high-income ones. Aims To systematically review prevalence studies for psychotic illness and major depression in prisoners, provide summary estimates and investigate sources of heterogeneity between studies using meta-regression. Method Studies from 1966 to 2010 were identified using ten bibliographic indexes and reference lists. Inclusion criteria were unselected prison samples and that clinical examination or semi-structured instruments were used to make DSM or ICD diagnoses of the relevant disorders. Results We identified 109 samples including 33 588 prisoners in 24 countries. Data were meta-analysed using random-effects models, and we found a pooled prevalence of psychosis of 3.6% (95% CI 3.1–4.2) in male prisoners and 3.9% (95% CI 2.7–5.0) in female prisoners. There were high levels of heterogeneity, some of which was explained by studies in low–middle-income countries reporting higher prevalences of psychosis (5.5%, 95% CI 4.2–6.8; P = 0.035 on meta-regression). The pooled prevalence of major depression was 10.2% (95% CI 8.8–11.7) in male prisoners and 14.1% (95% CI 10.2–18.1) in female prisoners. The prevalence of these disorders did not appear to be increasing over time, apart from depression in the USA ( P = 0.008). Conclusions High levels of psychiatric morbidity are consistently reported in prisoners from many countries over four decades. Further research is needed to confirm whether higher rates of mental illness are found in low- and middle-income nations, and examine trends over time within nations with large prison populations.

The epidemiology of trauma, PTSD, and other posttrauma disorders.

Abstract: Epidemiologic studies have reported that the majority of community residents in the United States have experienced posttraumatic stress disorder (PTSD)-level traumatic events, as defined in the DSM-IV. Only a small subset of trauma victims develops PTSD (<10%). Increased incidence of other disorders following trauma exposure occurs primarily among trauma victims with PTSD. Female victims of traumatic events are at higher risk for PTSD than male victims are. Direct evidence on the causes of the sex difference in the conditional risk of PTSD is unavailable. The available evidence suggests that the sex difference is not due to (a) the higher occurrence of sexual assault among females, (b) prior traumatic experiences, (c) preexisting depression or anxiety disorder, or (d) sex-related bias in reporting. Observed sex differences in anxiety, neuroticism, and depression, inducing effects of stressful experiences, might provide a theoretical context for further inquiry into the greater vulnerability of females to PTSD.

Risk for new onset of depression during the menopausal transition: the Harvard study of moods and cycles.

Abstract: Context Transition to menopause has long been considered a period of increased risk for depressive symptoms. However, it is unclear whether this period is one of increased risk for major depressive disorder, particularly for women who have not had a previous episode of depression. Objective To examine the association between the menopausal transition and onset of first lifetime episode of depression among women with no history of mood disturbance. Design Longitudinal, prospective cohort study. Setting A population-based cross-sectional sample. Participants Premenopausal women, 36 to 45 years of age, with no lifetime diagnosis of major depression (N = 460), residing in 7 Boston, Mass, metropolitan area communities. Main Outcome Measure Incidence of new onset of depression based on structured clinical interviews, Center for Epidemiologic Studies Depression Scale scores, and an operational construct for depression. Results Premenopausal women with no lifetime history of major depression who entered the perimenopause were twice as likely to develop significant depressive symptoms as women who remained premenopausal, after adjustment for age at study enrollment and history of negative life events. The increased risk for depression was somewhat greater in women with self-reported vasomotor symptoms. Conclusions The current study suggests that within a similarly aged population of women with no lifetime history of depression, those who enter the menopausal transition earlier have a significant risk for first onset of depression. Further studies are needed to determine more definitively whether other factors, such as the presence of vasomotor symptoms, use of hormone therapy, and the occurrence of adverse life events, independently modify this risk. Physical symptoms associated with the menopausal transition and mood changes seen during this period may affect many women as they age and may lead to a significant burden of illness.
