In 2 meta-analyses on gender differences in depression in nationally representative samples, we advance previous work by including studies of depression diagnoses and symptoms to (a) estimate the magnitude of the gender difference in depression across a wide array of nations and ages; (b) use a developmental perspective to elucidate patterns of gender differences across the life span; and (c) incorporate additional theory-driven moderators (e.g., gender equity). For major depression diagnoses and depression symptoms, respectively, we meta-analyzed data from 65 and 95 articles and their corresponding national data sets, representing data from 1,716,195 and 1,922,064 people in over 90 different nations. Overall, odds ratio (OR) = 1.95, 95% confidence interval (CI) [1.88, 2.03], and d = 0.27 [0.26, 0.29]. Age was the strongest predictor of effect size. The gender difference for diagnoses emerged earlier than previously thought, with OR = 2.37 at age 12. For both meta-analyses, the gender difference peaked in adolescence (OR = 3.02 for ages 13-15, and d = 0.47 for age 16) but then declined and remained stable in adulthood. Cross-national analyses indicated that larger gender differences were found in nations with greater gender equity, for major depression, but not depression symptoms. The gender difference in depression represents a health disparity, especially in adolescence, yet the magnitude of the difference indicates that depression in men should not be overlooked.

Women are about twice as likely as are men to develop depression during their lifetime. This Series paper summarises evidence regarding the epidemiology on gender differences in prevalence, incidence, and course of depression, and factors possibly explaining the gender gap. Gender-related subtypes of depression are suggested to exist, of which the developmental subtype has the strongest potential to contribute to the gender gap. Limited evidence exists for risk factors to be specifically linked to depression. Future research could profit from a transdiagnostic perspective, permitting the differentiation of specific susceptibilities from those predicting general psychopathologies within and across the internalising and externalising spectra. An integration of the Research Domain Criteria framework will allow examination of gender differences in core psychological functions, within the context of developmental transitions and environmental settings. Monitoring of changing socioeconomic and cultural trends in factors contributing to the gender gap will be important, as well as the influence of these trends on changes in symptom expression across psychopathologies in men and women.Copyright © 2017 Elsevier Ltd.

There is now a strong body of literature showing that bullying victimisation during childhood and adolescence precedes the later development of anxiety and depressive disorders. This study aimed to quantify the burden of anxiety and depressive disorders attributable to experiences of bullying victimisation for the Australian population.

To evaluate cross-sectional and prospective associations between short and long sleep duration and depressive symptoms in older adults (aged >65 years).The data from a subsample of the racially/ethnically diverse Northern Manhattan Study were analyzed. Depressive symptoms were assessed twice with the Center for Epidemiologic Studies Depression Scale (CES-D), approximately 5 years apart. The presence of depressive symptoms was defined as a CES-D score ≥16 or use of antidepressants. Self-reports of short (<6 h), intermediate (6-8 h) and long (≥9 h) sleep were assessed prior to the initial CES-D. Logistic regression was used to evaluate the cross-sectional associations between short and long sleep durations with depressive symptoms, using intermediate sleep as the reference. The prospective association between sleep duration and depression in a sample of participants without depressive symptoms at first CES-D was also analyzed. All models were adjusted for demographic, behavioral, and vascular risk factors.The initial sample consisted of 1110 participants: 62% women, 69% Hispanic, 17% black, 14% white. Short sleep was reported by 25%, intermediate sleep by 65%, and long sleep by 9%. Depressive symptoms were described in 25% of the initial sample. Short sleep, but not long sleep, was associated with depressive symptoms at baseline (adjusted OR 1.8, 95% CI 1.3-2.6), and at follow-up (adjusted OR 1.9, 95% CI 1.1-3.5; median follow-up = 5.1 years).Short sleep duration had a cross-sectional and prospective association with depressive symptoms in an urban multi-ethnic cohort of older adults.Copyright © 2017 Elsevier B.V.

Published guidelines describing effective adolescent depression care in primary care settings include screening, assessment, treatment initiation, and symptom monitoring. It is unclear the extent to which these steps are documented in patient health records.To determine rates of appropriate follow-up care for adolescents with newly identified depression symptoms in 3 large health systems.In this analysis conducted from March to September 2014, structured data retrospectively extracted from electronic health records were analyzed for 3 months following initial symptom identification to determine whether the patient was followed up and, if so, whether treatment was initiated and/or symptoms were monitored. Records were collected from 2 large health maintenance organizations in the western United States and a network of community health centers in the Northeast. The study group included adolescents (N = 4612) with newly identified depression symptoms, defined as an elevated score on the Patient Health Questionnaire (≥ 10) and/or a diagnosis of depression.Rates of treatment initiation, symptom monitoring, and follow-up care documented within 3 months of initial symptom identification.Among the 4612 participants, the mean (SD) age at index event was 16.0 (2.3) years, and 3060 were female (66%). Treatment was initiated for nearly two-thirds of adolescents (79% of those with a diagnosis of major depression; n =  023); most received psychotherapy alone or in combination with medications. However, in the 3 months following identification, 36% of adolescents received no treatment (n = 1678), 68% did not have a follow-up symptom assessment (n = 3136), and 19% did not receive any follow-up care (n = 854). Further, 40% of adolescents prescribed antidepressant medication did not have any documentation of follow-up care for 3 months (n = 356). Younger age (ages 15-17 years: odds ratio [OR], 0.78; 95% CI, 0.67-0.92 and ages 18-20 years: OR, 0.83; 95% CI, 0.70-0.99; P =.008), more severe initial symptoms (moderate: OR, 0.99; 95% CI, 0.82-1.21; moderate to severe: OR, 1.46; 95% CI, 1.19-1.80; and severe: OR, 2.14; 95% CI, 1.65-2.79; P <.001), and receiving a diagnosis (major depression/dysthymia: OR, 2.65; 95% CI, 2.20-3.20 and unspecified depression/adjustment disorder: OR, 1.75; 95% CI, 1.43-2.14; P <.001) were significantly associated with treatment initiation. Differences in rates of follow-up care were evident between sites (site 2: OR, 1.77; 95% CI, 1.45-2.16 and site 3: OR, 2.10; 95% CI, 1.72-2.57), suggesting that differences within health systems may also affect care received.Most adolescents with newly identified depression symptoms received some treatment, usually including psychotherapy, within the first 3 months after identification. However, follow-up care was low and substantial variation existed between sites. These results raise concerns about the quality of care for adolescent depression.
