Understanding Community-Specific Health Behaviors to Prevent Type 2 Diabetes and Depression in Rural Adolescents: A Qualitative Study.

Type 2 diabetes (T2D) and depression co-occur, and rates are on the rise in adolescents, disproportionately affecting teenagers in rural communities and those who identify as members of historically disadvantaged racial/ethnic groups. Addressing the promotion of health behaviors is important for prevention of these comorbid health concerns; however, disparities in their prevalence highlight that a healthy lifestyle is not equally accessible for all individuals. Thus, holistic and multi-level approaches that address structural inequities, leverage cultural and family assets, and are effectively integrated into the community are critically needed. This project is an initial phase of a broader community-academic collaboration that aims to address preventable chronic diseases and mental health in adolescents living in the rural Mountain West by tailoring an evidence-based health behavior and lifestyle intervention for these communities. Interviewers conducted semi-structured interviews with N = 19 individuals (n = 11 adolescents, 11-17years, n = 8 mothers) who lived in neighboring counties in the rural Mountain Western USA and had a family history of T2D. Interview schedules were developed by an interdisciplinary team, with community input, and covered topics such as food and staying active, stress, T2D risk, and community and culture. Using thematic analysis, data were reduced through coding, categorization, and development of themes. Data revealed three major themes: "Families Face Systemic Barriers to Health," "Family Routines Support Health," and "Connection is Crucial to Holistic Health." Findings reveal opportunities for addressing health inequities and developing effective, integrated T2D and depression prevention strategies within this specific community. They also potentially contain insights that may be applicable to others interested in adapting interventions for diverse groups.

Factors Influencing Depression in People with Disabilities:Individual and Interpersonal Levels

Abstract Depression is an increasingly important social problem, and this also applies to the disabled, a health-vulnerable group. Although the distribution and influencing factors of depression may be different among the disabled population (young adults vs. the elderly, older adults with disabilities vs. disabilities due to old age), only the high prevalence of depression among the disabled is generally reported. This study seeks to determine the distribution and influencing factors of depression in disabled people according to sociodemographic standards. This study employed data from the 2021 Panel Survey on People with Disabilities (National Unit Survey) to investigate the influence of individual-level factors (health behaviors, health level, environment) and interpersonal-level factors (social network) on depression. Multivariate logistic regression analysis was performed while controlling for demographic sociological factors and disability characteristic factors. The experience of depression was among elderly disabled individuals (age 50+: 40.9%) than younger ones (age 19-49: 36.1%), and in disability with aging (49.3%) versus aging with disabilities (39.2%) (P < 0.05). Chronic diseases, daily living assistance, living environment, and emotional support from family and neighbors affected both young and elderly disabled individuals. Specifically, among the elderly disabled, exercise frequency (aOR=0.78; [CI]0.63-0.97), social network size (aOR=0.87; [CI]0.82-0.93), and social interaction frequency (aOR=0.68; [CI]0.51-0.91) were significant. Disability with aging was influenced by exercise frequency (aOR=0.29; [CI]0.09-0.95) and emotional support (aOR=0.37; [CI]0.17-0.77) from peers. older adults with disabilities were affected by not only individual-level factors (exercise frequency) but also both functional (emotional support) and structural (size of social network, frequency of meetings) aspects of their interpersonal social networks. Key messages • Depression experiences among older adults with disabilities are influenced by both functional and structural social networks. • Developing depression prevention strategies for people with disabilities requires a customized approach that takes into account age-specific characteristics.

Gait speed, handgrip strength, and their combination, and risk of depression in later life: Evidence from a prospective study of community-dwelling older adults

ObjectiveThis study investigated the association between gait speed, handgrip strength, and their combination, and the risk for developing clinically relevant depressive symptoms in community-dwelling older adults. MethodsA secondary analysis was conducted using data from the ASPirin in Reducing Events in the Elderly study. Participants were community-dwelling older adults in Australia and the United States of America followed for a median (interquartile range) of 3.97 (2.26) years. Baseline handgrip strength and gait speed were used as exposure variables, and their combination categories were also explored. Depression was measured using the modified Center for Epidemiological Studies Depression 10-item scale (CES-D 10). Cox regression was used to estimate Adjusted Hazard Ratios (AHR) with 95 % Confidence Intervals (CI) after adjusting for a range of potential confounders. ResultA total of 17,231 participants (55.3 % women) were included in the analysis. Slow gait and weak grip at baseline were associated with the risk of depression (AHR: 1.20; CI: 1.11–1.29 and 1.14; 1.06–1.23, respectively). The combination of the two physical performance measures was associated with a 31 % increase in the risk of depression (1.31; 1.16–1.47) and a significant dose-response association was observed for quintiles of gait and grip with depression. LimitationsAlthough the CES-D 10 is a validated scale, it is a self-reported tool rather than a clinical diagnosis of depression. ConclusionLow physical function may be a risk factor for depression in older adults. This highlights the inextricable link between the physical and mental health of older adults, which can inform potential clinical and public health prevention strategies for depression in later life.

Association between long-term visit-to-visit blood pressure variability and depression among Chinese middle-aged and older adults

ABSTRACT Background Whether there is a longitudinal association between long-term blood pressure variability (BPV) and subsequent depression among Chinese adults remains inconclusive. Methods This study utilized data from a nationwide cohort of the China Health and Retirement Longitudinal Study, which included participants aged > 45 years without prevalent psychiatric or memory-related diseases. The intra-individual coefficient of variation (CV) and standard deviation (SD) across 3 visits from 2011 to 2015 were used to examine the long-term variability in systolic BP (SBP) and diastolic BP (DBP). The depressive symptoms were examined using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10), and moderate-to-severe depression was defined as CES-D-10 ≥ 15. Results A total of 5,249 participants (mean age: 61.4 ± 8.1 years, 46.5% were men) were included in the current analysis. Individuals in the highest quartile of both BP CV and SD were independently correlated with a higher total CES-D-10 score compared to those in the lowest quartile after multivariable adjustment. 1,070 participants (20.4%) had moderate-to-severe depression during the 3-year follow-up period. Participants in the Q4 of SBP and DBP CV had 1.23-fold higher odds (95% CI: 1.01, 1.49) and 1.20-fold higher odds (95% CI: 1.01, 1.41) of moderate-to-severe depression compared to those in Q1. Subgroup analyses revealed that men with higher BP CVs had a greater risk of severe depressive symptoms (p for SBP CV-by-sex interaction = 0.050, p for SBP CV-by-sex interaction = 0.025). Conclusions Depression was common among Chinese middle-aged and older adults and long-term visit-to-visit BPV was positively associated with depressive symptoms, highlighting the importance of implementing intensive prevention strategies for depression and enhancing blood pressure monitors in China.

Associations of allostatic load with sociodemographic factors, depressive symptoms, lifestyle, and health characteristics in a large general population-based sample

ObjectiveWe examined the associations between allostatic load (AL) and sociodemographic factors, depressive symptoms, lifestyle and health characteristics in a population-based sample of 4993 adults in Finland. MethodsThirteen biomarkers were used to construct AL. High AL was defined as scoring highly in ≥4 items. ResultsAL scores of 4 and above were exceeded in the age group of 45–54 years in men and 65–74 years in women. Age was the strongest predictor for belonging to the high AL score group. In addition, elevated depressive symptoms (BDI-6 ≥ 4), male sex, not engaging in physical exercise, high alcohol use and a low level of education were associated with an increased likelihood of belonging to the high AL group. ConclusionThe older the participants were, the greater their AL burden was. However, AL burden increased more steeply as a function of age in men. In addition to lifestyle interventions, effective prevention strategies for depression at the population level could have a major public health impact in reducing the accumulation of AL burden.

What is the place of universal, selective, and indicated prevention strategies for depression and other mood disorders?

Given the global prevalence of depression and other major mood disorders, the evidence of increasing rates among younger cohorts, the limited capacity of most treatment systems to respond to increasing demands for care, and the reality that services do not connect with a large proportion of those living with depressive disorders, a greater emphasis is being placed on our capacity to prevent the onset, recurrence, or persistence of these disabling conditions (Herrman et al., 2022).

Risk factors and strategies for prevention of depression, anxiety and eating disorders among adolescents during the coronavirus disease 2019 (COVID-19) pandemic: a review.

The purpose of this review is to identify prevalent trends and risk factors in depression, anxiety, and eating disorders in the adolescent population in the post coronavirus disease 2019 (COVID-19) scenario. We examined the literature published on adolescent mental health since the COVID-19 pandemic. We chose to summarize studies published from 2019 to 2022, using bibliographic search tools. We developed criteria for selecting articles for our review using diagnostic indicators and keywords. Mental health conditions such as depression, anxiety and eating disorders are commonly prevalent in this population and have shown increasing rates in the past three years. Some risk factors associated with these diagnoses include reduction in social interaction, increased workloads, routine shifts, sleep quality, social media usage and parental involvement. Routines, sleep cycles, physical activity, and social media should all be considered as a part of prevention in this population. Approaches that seem to be successful include maintaining social ties and avoiding negative social media usage with harmful content. Increased global public awareness, as well as parental awareness, through media campaigns, is critical to slowing the spread of mental health challenges in adolescents and teenagers in the post-COVID-19 era.

Sleep and Healthy Aging Research on Depression (SHARE-D) randomized controlled trial: Protocol overview of an experimental model of depression with insomnia, inflammation, and affect mechanisms in older adults

Depression, one of the most common diseases in older adults, carries significant risk for morbidity and mortality. Because of the burgeoning population of older adults, the enormous burden of late-life depression, and the limited efficacy of current antidepressants in older adults, biologically plausible models that translate into selective depression prevention strategies are needed. Insomnia predicts depression recurrence and is a modifiable target to prevent incident and recurrent depression in older adults. Yet, it is not known how insomnia gets converted into biological- and affective risk for depression, which is critical for identification of molecular targets for pharmacologic interventions, and for refinement of insomnia treatments that target affective responding to improve efficacy. Sleep disturbance activates inflammatory signaling and primes immune responses to subsequent inflammatory challenge. In turn, inflammatory challenge induces depressive symptoms, which correlate with activation of brain regions implicated in depression. This study hypothesizes that insomnia serves as a vulnerability factor for inflammation-related depression; older adults with insomnia will show heightened inflammatory- and affective responding to inflammatory challenge as compared to those without insomnia. To test this hypothesis, this protocol paper describes a placebo-controlled, randomized, double-blind study of low dose endotoxin in older adults (n = 160; 60–80 y) with insomnia vs. comparison controls without insomnia. The aims of this study are to examine differences in depressive symptoms, measures of negative affective responding, and measures of positive affective responding as a function of insomnia and inflammatory challenge. If the hypotheses are confirmed, older adults with two “hits”, insomnia and inflammatory activation, would represent a high risk group to be prioritized for monitoring and for depression prevention efforts using treatments that target insomnia or inflammation. Moreover, this study will inform the development of mechanism-based treatments that target affect responses in addition to sleep behaviors, and which might also be coupled with efforts to reduce inflammation to optimize efficacy of depression prevention.

Prevalence and Determinants of Depressive Symptoms among Young Adolescents in Malaysia: A Cross-Sectional Study.

Depression is the most common mental health problem affecting adolescents globally, wherein its increasing prevalence together with the negative health impacts escalates the need for further research in this area. This work determined the prevalence and factors associated with depressive symptoms among young adolescents in Malaysia. A total of 1350 adolescent aged 13 to 14 years in school across nine secondary schools in Selangor state, Malaysia participated in a cross-sectional study. Independent variables were examined using the using the Global School-Based Student Health Survey included age, gender, ethnicity, alcohol intake, smoking and illicit drug use, loneliness, bullying, parental marital status, income and supervision; and the Health Literacy and Stigma questionnaire examined mental health literacy levels. Depressive symptoms were the dependent variable which was examined using the Center for Epidemiology Study Depression (CESD) instrument. Prevalence of depressive symptoms among all participants was 19 % (95% CI [16.9, 21.2]), with a higher prevalence of depressive symptoms being reported among females 26.3% (95% CI [23.0, 29.8]) compared to males 11.7% (95% CI [9.4, 14.4]). Determinants namely females (AOR = 3.83; 95% CI [2.66, 5.52]), smoking (AOR = 6.16; 95% CI [3.15, 12.05]), been bullied (AOR = 3.70; 95% CI [2.51, 5.47]), felt lonely (AOR = 10.46; 95% CI [7.09, 15.42]) and having no parental supervision (AOR = 1.79; 95% CI [1.26, 2.53]) significantly increased the odds of depressive symptoms among all adolescents in the multivariate model. In addition, feeling lonely, being bullied and smoking were identified as common significant determinants of depressive symptoms across both genders. Feeling lonely (65% to 71%) and being bullied (10% to 19%) were ranked as the most important determinants of depressive symptoms among young adolescents. Tackling these factors would be instrumental in helping decision makers formulate depression prevention strategies and activities for adolescents.

Decrease in Gait Speed Over Time Is Associated With Increase in Number of Depression Symptoms in Older Adults With Type 2 Diabetes.

We examined the cross-sectional and longitudinal relationships of motor functions with depression in older adults with type 2 diabetes (T2D). Participants (n = 984) were from the longitudinal Israel Diabetes and Cognitive Decline (IDCD) study. They were initially cognitively normal and underwent evaluations of motor functions (grip strength and gait speed) and of depression (using the 15-item version of the Geriatric Depression Scale [GDS]) approximately every 18 months. We applied Hierarchical Linear Mixed Models (HLMM) to investigate the associations between motor functions and depression adjusting for sociodemographic, cardiovascular factors, overall cognitive score, and subjective report of exhaustion. Participants' baseline characteristics were 72 (±5) years of age (59.6% males), 13 (±4) years of education, Mini-Mental Status Exam (MMSE) score of 28.01 (±1.78), and a GDS score of (2 ± 2.00), consistent with normal cognitive status and lack of major affective symptomatology. Slower gait speed at baseline was associated with higher GDS scores (p = .001) and with their increase over time (p = .049). A decrease in walking speed from baseline was associated with an increase in GDS scores (p = .015). Lower grip strength at baseline was associated with higher GDS scores (p = .002), but not with trajectories in GDS scores over time. A faster decrease in grip strength from baseline was associated with a faster increase in GDS scores (p = .022). Both gait speed and grip strength are cross-sectionally associated with depression. However, only gait speed and its decrease over time can potentially be used to predict incident depression symptoms, thus facilitating the introduction of depression prevention strategies.

Primary prevention of depression in head and neck cancer patients: a scoping review.

To conduct a scoping review of the literatureon psychological interventions directed to identify primary prevention strategies for depression among adult head and neck cancer (HNC) patients. Systematic searches were conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Review including relevant studies within the PubMed, PsycINFO, and EMBASE databases. Two authors independently screened the searches and reviewed the included articles according to the predetermined eligibility criteria based on the PICOS format. Studies included subjects with previous or current diagnosis of depression were excluded. The risk of bias assessment of these trials was conducted following the Cochrane tool for assessing the risk of bias in randomized trials. The search was repeated prior to submission to ensure all current articles meeting criteria were included. The search yielded 875 studies. The title and abstract screen, followed by the review of full texts identified five articles that met inclusion criteria. Four were randomized controlled trials (RCT) and the fifth was a non-randomized but controlled study. Different psychosocial interventions were used, including psycho-educational interventions, psychosocial counseling, and pharmacotherapy. All studies established the diagnosis of depression or screened for the diagnosis using standardized psychiatric assessment tools, either Diagnostic and Statistical Manual of Mental Disorders criteria or validated patient reported outcome measures. The average follow-up periods after intervention was 9.8months. There was a significant decrease in the incidence of depression or depressive symptoms favoring the intervention group in three out of the five studies that were included. Psychological interventions identified thus far studying primary prevention of depression in HNC patients show promising results. However, the paucity of data and heterogeneity of the interventions challenges the ability to compare the prevention modalities and outcomes. Future well-designed RCTs with large sample sizes are recommended to better conclude a result of effectiveness.

The changing relationship between health risk behaviors and depression among birth cohorts of Canadians 65+, 1994-2014.

The older adult residents of Canada form an increasingly larger proportion of the population and are becoming better educated and have more income. Depression is a common mental disorder, particularly among seniors. Several health risk behaviors-physical inactivity, tobacco use, and alcohol consumption-are linked to mental health problems. This study examines whether these health risk behaviors and their association with depression among Canadians 65+ born in eight cohorts between 1910-1914 and 1945-1949, have changed. Pooled data drawn from 11 nationally representative health surveys conducted by Statistics Canada between 1994 and 2014 are analyzed-88,675 survey participants met inclusion criteria. Depression was assessed by the Composite International Diagnostic Interview-Short Form. Health risk behaviors examined were physical activity/inactivity, smoking, and alcohol use. A Cochran Armitage trend test for categorical outcomes and a log-binomial modeling for binary outcomes were used to estimate the risk ratios across cohorts. The proportions of Canadians 65+ who are physically active, regular drinkers, and regular smokers have increased; however, depression prevalence fluctuated non-significantly. Depression increased among all health risk behaviors, particularly in recent birth cohorts. Depression among physically inactive seniors, current smokers, and non-drinkers was significantly higher than among active, non-smokers, and regular drinkers (all P < 0.05). Physical inactivity and smoking-attributable depression risk showed an increasing linear trend across birth cohorts (RR = 1.67, P < 0.001; RR = 1.79, P < 0.001). For seniors born between 1915 and 1944, regular drinking was associated with a significant decrease in depression (all P < 0.001), but the protective effects of regular drinking became non-existent in the most recent 1945-1949 birth cohort (RR = 1.09, P < 0.05, after adjusting for covariates). Inactivity and smoking were consistently associated with a significantly increased risk of depression among Canadian residents 65+, with smoking becoming more firmly connected to depression risk in more recent birth cohorts. In contrast, moderate alcohol use was associated with a decreased risk of depression, but that protective effect ceased in most recent birth cohort. Identifying the changing relationships between health risk behaviors and depression is meaningful for developing prevention strategies for depression and other emotional and mental health problems.

Meta-Analysis: Relapse Prevention Strategies for Depression and Anxiety in Remitted Adolescents and Young Adults

Depression and anxiety cause a high burden of disease and have high relapse rates (39%-72%). This meta-analysis systematically examined effectiveness of relapse prevention strategies on risk of and time to relapse in youth who remitted. PubMed, PsycInfo, Embase, Cochrane, and ERIC databases were searched up to June 15, 2021. Eligible studies compared relapse prevention strategies to control conditions among youth (mean age 13-25 years) who were previously depressed or anxious or with≥30% improvement in symptoms. Two reviewers independently assessed titles, abstracts, and full texts; extracted study data; and assessed risk of bias and overall strength of evidence. Random-effects models were used to pool results, and mixed-effects models were used for subgroup analyses. Main outcome was relapse rate at last follow-up (PROSPERO ID: CRD42020149326). Of 10 randomized controlled trials (RCTs) that examined depression, 9 were eligible for analysis: 4 included psychological interventions (n= 370), 3 included antidepressants (n= 80), and 2 included combinations (n= 132). No RCTs for anxiety were identified. Over 6 to 75 months, relapse was half as likely following psychological treatment compared with care as usual conditions (k= 6; odds ratio 0.56, 95% CI 0.31 to 1.00). Sensitivity analyses including only studies with≥50 participants (k= 3), showed similar results. Over 6 to 12 months, relapse was less likely in youth receiving antidepressants compared with youth receiving pill placebo (k= 3; OR 0.29, 95% CI 0.10 to 0.82). Quality of studies was suboptimal. Relapse prevention strategies for youth depression reduce risk of relapse, although adequately powered, high-quality RCTs are needed. This finding, together with the lack of RCTs on anxiety, underscores the need to examine relapse prevention in youth facing these common mental health conditions.

The Mediterranean Lifestyle and the Risk of Depression in Middle-Aged Adults

BackgroundRecent evidence has indicated a greater number of protective factors are associated with a greater decreased risk for depression and depressive symptoms compared with individual factors alone. Moreover, adherence to healthy modifiable lifestyle behaviors may lower the risk of depression regardless of underlying genetic risk. ObjectivesWe longitudinally evaluated the association of the Mediterranean lifestyle (MEDLIFE) with the risk of depression. MethodsWe prospectively analyzed data from 15,279 participants (6089 men and 9190 women, mean age 37 y) in the Seguimiento Universidad de Navarra cohort. The MEDLIFE index is composed of 28 items on food consumption, dietary habits, physical activity, rest, social habits, and conviviality, each of which was assigned 0 or 1 point. Final scores ranged from 0 to 28 points and were categorized into quartiles of MEDLIFE adherence. Cox proportional regression models determined the association of total MEDLIFE adherence, each item, and block with incident depression. ResultsAfter a mean follow-up of 11.7 y, 912 (6%) incident cases of depression were reported. The mean ± SD final score for MEDLIFE adherence was 11.9 ± 2.7 points. The multivariable model showed that compared with the first quartile, the second and third quartiles of MEDLIFE adherence were significantly associated with a decreased relative risk for incident depression (HR: 0.82; 95% CI: 0.69, 0.96 and HR: 0.74; 95% CI: 0.61, 0.89, respectively). The fourth quartile did not show a statistically significant association with incident depression (HR: 0.89; 95% CI: 0.73, 1.09). ConclusionsMEDLIFE adherence may decrease the risk of depression in a Spanish cohort of university graduates. Given no clear association was observed among the highest MEDLIFE adherence, future studies are warranted to better understand the nature of this association. Evidence on MEDLIFE, beyond the Mediterranean diet, may contribute toward more effective prevention strategies for depression.

U.S. Simulation of Lifetime Major Depressive Episode Prevalence and Recall Error

Simulation models can improve measurement and understanding of mental health conditions in the population. Major depressive episodes are a common and leading cause of disability but are subject to substantial recall bias in survey assessments. This study illustrates the application of a simulation model to quantify the full burden of major depressive episodes on population health in the U.S. A compartmental model of major depressive episodes that explicitly simulates individuals' under-reporting of past episodes was developed and calibrated to 2005-2017 National Surveys on Drug Use and Health data. Parameters for incidence of a first major depressive episode and the probability of under-reporting past episodes were estimated. Analysis was conducted from 2017 to 2019. The model estimated that 30.1% of women (95% range: 29.0%-32.5%) and 17.4% of men (95% range: 16.7%-18.8%) have lifetime histories of a major depressive episode after adjusting for recall error. Among all adults, 13.1% of women (95% range: 8.1%-16.5%) and 6.6% of men (95% range: 4.0%-8.3%) failed to report a past major depressive episode. Under-reporting of a major depressive episode history in adults aged >65 years was estimated to be 70%. Simulation models can address knowledge gaps in disease epidemiology and prevention and improve surveillance efforts. This model quantifies the under-reporting of major depressive episodes and provides parameter estimates for future research. After adjusting for under-reporting, 23.9% of adults have a lifetime history of major depressive episodes, which is much higher than based on self-report alone (14.0%). Far more adults would benefit from depression prevention strategies than what survey estimates suggest.

A cluster randomized controlled trial of an online psychoeducational intervention for people with a family history of depression

BackgroundPeople with a family history of major depressive disorder (MDD) or bipolar disorder (BD) report specific psychoeducational needs that are unmet by existing online interventions. This trial aimed to test whether an interactive website for people at familial risk for depression (intervention) would improve intention to adopt, or actual adoption of, depression prevention strategies (primary outcome) and a range of secondary outcome measures.MethodsIn this cluster randomised trial, primary care practises were randomised to either provide the link to the intervention or the control website. Primary health care attendees were invited by letter to opt into this study if they had at least one first-degree relative with MDD or BD and were asked to complete online questionnaires at baseline and 2-week follow-up.ResultsTwenty general practices were a randomized, and 202 eligible patients completed both questionnaires. Thirty-nine (19.3%) of participants were male and 163 (80.7%) female. At follow-up, compared to controls, the intervention group: (i) were more likely to intend to undergo, or to have actually undergone, psychological therapies (OR = 5.83, 95% CI: 1.58–21.47, p = .008); (ii) had better knowledge of depression risk factors and prevention strategies (mean difference = 0.47, 95% CI: 0.05–0.88, p = .029); and (iii) were more likely to accurately estimate their lifetime risk of developing BD (mean difference = 11.2, 95% CI: -16.52– -5.73, p < .001). There were no statistically significant between-group differences in change from baseline to follow up for any of the remaining outcome measures (Patient Health Questionnaire, Perceived Devaluation-Discrimination Questionnaire and Perceived Risk of Developing MDD).ConclusionThe opt-in nature of the study may have led to participation bias, e.g. underrepresentation of males, and hence may limit generalisability to the broader population at familial risk for depression. This is the first website internationally focusing specifically on informational needs of those at familial risk of depression. Our interactive website can play an important role in improving the outcomes of individuals at familial risk for depression. Testing the intervention in other settings (e.g. psychology, psychiatry, genetic counselling) appears warranted.Trial registrationThe study was prospectively registered with the Australian and New Zealand Clinical Trials Group (Registration no: ACTRN12613000402741).

Depressive spectrum states in a population-based cohort of 70-year olds followed over 9years.

Depression may be understood as a spectrum of more or less symptomatic states. Little is known about the long-term course of these states in older populations. We examined the prevalence and course of depressive states of different severity in a Swedish population sample of older people followed over 9years. A population-based sample of 70-year olds without dementia (N=563, response rate 71.1%) underwent a psychiatric examination; 450 survivors without dementia were reexamined at ages 75 and/or 79years. Three depressive spectrum states were defined: major depression (MD), minor depression (MIND), and subsyndromal depression (SSD). The cumulative 9-year prevalence of any depressive spectrum state was 55.3% (MD 9.3%, MIND 27.6%, SSD 30.9%). The cross-sectional prevalence increased with age, especially for MIND and SSD. Among those with baseline MD and MIND, 75.0% and 66.7%, respectively, had MD or MIND during follow-up. Among those with SSD, 47.2% had SSD also during follow-up and 36.1% had MD or MIND. Among those with MD during follow-up, 63.1% were in a depressive spectrum state at baseline. The corresponding proportion was 30% for those with MIND (but no MD) during follow-up. In this population-based sample, over half experienced some degree of depression during their eighth decade of life. The findings give some support for the validity of a depressive spectrum in older adults. Most new episodes of major depression occurred in people who were in a depressive spectrum state already at baseline, which may have implications for late-life depression prevention strategies.

The role of socio-economic status in depression: results from the COURAGE (aging survey in Europe)

BackgroundLow socio-economic status (SES) has been found to be associated with a higher prevalence of depression. However, studies that have investigated this association have been limited in their national scope, have analyzed different components of SES separately, and have not used standardized definitions or measurements across populations. The aim of the current study was to evaluate the association between SES and depression across three European countries that represent different regions across Europe, using standardized procedures and measurements and a composite score for SES.MethodNationally-representative data on 10,800 individuals aged ≥18 from the Collaborative Research on Ageing in Europe (COURAGE) survey conducted in Finland, Poland and Spain were analyzed in this cross-sectional study. An adapted version of the Composite International Diagnostic Interview was used to identify the presence of depression, and SES was computed by using the combined scores of the total number of years educated (0–22) and the quintiles of the country-specific income level of the household (1–5). Multivariable logistic regression was used to assess the association between SES and depression.ResultsFindings reveal a significant association between depression and SES across all countries (p ≤ 0.001). After adjusting for confounders, the odds of depression were significantly decreased for every unit increase in the SES index for Finland, Poland and Spain. Additionally, higher education significantly decreased the odds for depression in each country, but income did not.ConclusionThe SES index seems to predict depression symptomatology across European countries. Taking SES into account may be an important factor in the development of depression prevention strategies across Europe.

Preferred Features of E-Mental Health Programs for Prevention of Major Depression in Male Workers: Results From a Canadian National Survey.

BackgroundMajor depression is a prevalent mental disorder and imposes considerable burden on health and productivity. Men are not immune to major depression, yet they often delay seeking help because of perceived stigma and gender norms. E-mental health programs hold potential for early prevention of major depression. However, we have little knowledge about men’s preferences for design features of e-mental health programs.ObjectivesThe objective of this study was to (1) estimate and compare the proportions of Internet use for medical information, preferred design features, and likely use of e-mental health programs; (2) examine factors associated with the likely use of e-mental health programs; and (3) understand potential barriers to the use of e-mental health programs among Canadian working men, who were at high risk of a major depressive episode (MDE).MethodsA cross-sectional survey in 10 Canadian provinces was conducted between March and December 2015. Random digit dialing method was used through household landlines and cell phones to collect data from 511 working men who were at high risk of having an MDE and 330 working men who were at low risk of having an MDE.ResultsHigh-risk men were more likely to endorse the importance of accessing health resources on the Internet than low-risk men (83.4% vs 75.0%, respectively; P=.01). Of the 17 different features assessed, the top three features most likely to be used by high-risk men were: “information about improving sleep hygiene” (61.3%), “practice and exercise to help reduce symptoms of stress and depression” (59.5%), and “having access to quality information and resources about work stress issues” (57.8%). Compared with men at low risk for MDE, men at high risk for MDE were much more likely to consider using almost every one of the different design features. Differences in preferences for the design features by age among men at high risk of MDE were found only for 3 of 17 features. Differences in preferences for design features between English- and French-speaking participants were found only for 4 out of the 17 features. Analysis of qualitative data revealed that privacy issues, perceived stigma, ease of navigation, personal relevance, and lack of personal interaction, time, and knowledge were identified as barriers to the use of e-mental health programs in working men who were at high risk of MDE.ConclusionE-mental health programs may be a promising strategy for prevention of depression in working men. Development of e-mental health programs should consider men’s preferences and perceived barriers to enhance the acceptability of this approach.

Suicidal behaviour in first-episode non-affective psychosis: Specific risk periods and stage-related factors

Suicide is a major cause of premature death in psychosis. Earlier stages have been associated with higher risk. However, such risk periods have not been specifically determined and risk factors for suicidal behaviour may change over those periods, which may have crucial implications for suicide prevention. The aim of this study was to determine and characterize the highest risk period for suicide in a representative sample of first-episode psychosis (FEP) patients. Suicidal behaviour prior to first presentation of psychosis and during a 3-year follow-up was examined in a sample of 397 individuals. Risk factors for suicidal behaviour during specific time periods were investigated and compared. The greatest suicide risk was found during the month before and 2 months after first contact with psychiatric services (i.e., ‘early’ attempts). Severity of depressive symptoms and cannabis use emerged as predominant risk factors across time. ‘Early’ attempters were characterized as being male, living in urban areas, having poor premorbid adjustment, requiring hospitalization, scoring higher on anxiety measures and unusual thought content than non-attempters. Greater suspiciousness and more severe depressive symptoms distinguished the ‘late’ attempters. In conclusion, there is a specific high risk period for suicide in FEP around the time of the first presentation. Early intervention programmes targeting phase-specific risk factors, particularly psychotic symptoms management and secondary depression prevention strategies may be useful for suicide prevention in psychosis.
