RESUMEN

OBJECTIVES: This study explored the mechanisms by which physical activity was associated with depressive symptoms in multi-ethnic (Han, Yi and Tibetan) adolescents in southwest China. The mediating role of insomnia in the association of physical activity with depressive symptoms, the moderating role of resilience in this mediation model and the moderating role of parental absence in the moderated mediation model were also examined. DESIGN: A cross-sectional survey. SETTING: In southwest China (Sichuan Province and Tibet Autonomous Region). PARTICIPANTS: 3195 adolescents from a school-based survey conducted between April and October 2020. METHODS: There were 3143 valid samples in this study (47.2% males with mean age=12.88±1.68 years). Structural equation models were developed to estimate the direct and mediating effect, and the moderating effect. Multigroup comparison was performed to examine the differences and similarities of the moderated mediation model across three parental absence subgroups: (1) both parents present, (2) one parent absent and (3) both parents absent. RESULTS: As hypothesised, physical activity was significantly and positively associated with the reduction of depressive symptoms in adolescents. Insomnia partially mediated the effect of physical activity on depressive symptoms. In addition, resilience moderated the direct and indirect effects of physical activity (through insomnia) on depressive symptoms. Finally, the multigroup comparison indicated the moderating effect of parental absence on the moderated mediation model. CONCLUSIONS: Physical activity was associated with alleviating insomnia symptoms among adolescents, thus correlating with the improvement of their depressive symptoms. Resilience was associated with enhancing the beneficial effects of physical activity, further improving depressive symptoms among adolescents, especially those with both absent parents. It is evident that physical activity interventions should be further incorporated into public health programmes to foster the physical and mental health of left-behind adolescents in southwest China.

RESUMEN

OBJECTIVES: To compare the level of knowledge of depression, recognition ability and attitudes towards depression among urban and rural residents in Beijing. DESIGN: A cross-sectional study. SETTING: Six districts in Beijing, China, 2021. PARTICIPANTS: A total of 6463 participants aged 18 years and above who had lived for more than 6 months over the last year in Beijing were selected in this study. OUTCOME: The awareness and recognition of depression and the views of residents towards people with depression. RESULTS: A total of 2554 urban and 2043 rural residents completed the survey. Urban residents of Beijing exhibited a higher average total score on the Depression Knowledge Questionnaire [(20.4±3.3) vs (18.7±3.5), p<0.001] and a higher rate of correctly identifying individuals with depression (47.9% vs 36.6%, p<0.001) than their counterparts in rural areas. Residents who correctly identified people with depression had higher scores on the Depression Knowledge Questionnaire. Depression knowledge varied significantly among urban and rural residents. The multivariate linear regression analysis revealed that rural residents scored significantly lower on measures of depression knowledge compared with urban residents (B=-0.83, 95%CI=-1.03 to -0.63, p<0.001). Older individuals (aged 50+) showed lower understanding compared with the 18-49 age group, with significant negative regression coefficients (Urban: B=-1.06, Rural: B=-1.35, both p<0.001). Higher educational levels were positively associated with greater depression knowledge (Urban: B=1.40, Rural: B=1.21, both p<0.001). Employment was linked to higher knowledge levels than unemployment (Urban: B=-0.60, Rural: B=-0.58, both p=0.00). A monthly income of 8000 yuan or more correlated with better depression understanding than lower incomes (Urban: B=0.81, Rural: B=1.04, both p<0.001). Additionally, in urban areas, unmarried residents scored higher in depression knowledge than those divorced (B=-0.55, p=0.04). Residents in urban areas had relatively positive attitudes towards individuals with depression. CONCLUSIONS: Rural residents of Beijing had lower levels of knowledge and recognition of depression and more negative attitudes towards individuals with depression than those from urban areas. The health authority needs to focus on the poor level of knowledge and increase mental health resources in rural areas as a priority site for future psychological popularisation efforts.

RESUMEN

INTRODUCTION: Major depressive disorder (MDD), the second leading cause of disability globally, is considered to be associated with a consequent deterioration in the quality of life and can lead to a major economic burden on medical service and suicide-related costs. Previous research has shown that acupuncture may be beneficial for treating MDD. However, there is a lack of rigorous evidence from previous studies comparing acupuncture with antidepressant medications. This study aims to assess the therapeutic potential of acupuncture in the management of depressive disorders. METHODS AND ANALYSIS: A multicentre, randomised, participant-blind, sham-controlled, 2×2 factorial clinical trial, Acupuncture and Escitalopram for Treating Major Depression Clinical Study, aims to compare the efficacy of acupuncture versus escitalopram in treating depression. This study will be conducted at three hospitals in China, enrolling 260 patients with moderate-to-severe major depression, as defined by DSM-5 criteria and Hamilton Depression Rating Scale (HDRS-17) Scores above 17. Participants will be randomly assigned in equal proportions to one of four groups (acupuncture/escitalopram, sham acupuncture/escitalopram, acupuncture/placebo and sham acupuncture/placebo) and undergo 30 sessions across 10 weeks. The primary outcome is change in HDRS-17 Score and secondary outcomes include BDI, Clinical Global Impression, Generalised Anxiety Disorder-7 and Mini-Mental State Examination Scores, alongside potential biological markers. ETHICS AND DISSEMINATION: Ethical approval for the study was granted by the Ethics Committees of the Seventh People's Hospital of Shanghai University of Traditional Chinese Medicine (2023-7th-HIRB-020), Shanghai Mental Health Centre (2022-86) and Shanghai Pudong New Area Hospital of Traditional Chinese Medicine (2023-003). Informed consent will be obtained from all participants. The study's findings are intended for publication in a scholarly journal. TRIAL REGISTRATION: NCT05901571.

RESUMEN

BACKGROUND: Depression and anxiety are increasingly prevalent in adolescents. The Brief Educational Workshops in Secondary Schools Trial investigated the effectiveness of a brief self-referral stress workshop programme for sixth-form students aged 16-18 years old. OBJECTIVE: This study conducted a secondary analysis on the outcomes of participants with elevated depressive symptoms at baseline. METHODS: This is an England-wide, multicentre, cluster randomised controlled trial to evaluate the clinical effectiveness and cost-effectiveness of a brief cognitive-behavioural therapy workshop (DISCOVER) compared with treatment-as-usual (TAU) (1:1). The primary outcome was depression symptoms (Mood and Feelings Questionnaire (MFQ)) at 6-month follow-up, using the intention-to-treat (ITT) population and analysed with a multilevel linear regression estimating a between-group adjusted mean difference (aMD). Cost-effectiveness, taking a National Health Service (NHS) and personal social services perspective, was explored using quality-adjusted life years (QALYs). FINDINGS: Between 4 October 2021 and 10 November 2022, 900 adolescents at 57 schools were enrolled. 314 students were identified as having elevated symptoms of depression at baseline (>27 on MFQ). In this prespecified subgroup, the DISCOVER arm included 142 participants and TAU included 172. ITT analysis included 298 participants. Primary analysis at 6 months found aMD to be -3.88 (95% CI -6.48, -1.29; Cohen's d=-0.52; p=0.003), with a similar reduction at 3 months (aMD=-4.00; 95% CI -6.58, -1.42; Cohen's d=0.53; p=0.002), indicating a moderate, clinically meaningful effect in the DISCOVER arm. We found an incremental cost-effectiveness ratio of £5255 per QALY, with a probability of DISCOVER being cost-effective at between 89% and 95% compared with TAU. CONCLUSIONS AND CLINICAL IMPLICATIONS: DISCOVER is clinically effective and cost-effective in those with elevated depressive symptoms. This intervention could be used as an early school-based intervention by the NHS. TRIAL REGISTRATION NUMBER: ISRCTN90912799.

RESUMEN

INTRODUCTION: Premature birth and very low birth weight (VLBW) are leading causes of neonatal mortality. Almost all premature infants experience hyperbilirubinaemia. Administering probiotics to breastfeeding mothers may positively affect infant outcomes. This trial aims to investigate whether probiotic supplementation for mothers with VLBW infants affects total serum bilirubin levels and postpartum depression scores (primary outcomes), as well as some other neonatal and maternal outcomes (secondary outcomes). METHODS AND ANALYSIS: This is a randomised, double-blind, placebo-controlled superiority trial with two parallel arms. Participants, caregivers and outcome assessors will be blinded. A total of 122 breastfeeding mothers of neonates with a birth weight of 1000-1500 g, along with their infants within 48 hours of birth, will be assigned to either the probiotic or placebo group in a 1:1 ratio through block randomisation, stratified by singleton and twin births. The intervention will involve oral administration of probiotics containing Lactobacillus paracasei 431 and Bifidobacterium lactis BB-12, or an indistinguishable placebo, for 42-45 days. Outcomes will be assessed through daily observations, laboratory assessments and the Edinburgh Postpartum Depression Scale. Adverse events will also be documented. Modified intention-to-treat analyses will be employed for the primary and secondary outcomes, excluding participants lost to follow-up from all postintervention assessments. ETHICS AND DISSEMINATION: This study protocol has been approved by the Medical University of Tabriz Ethics Committee (IR.TBZMED.REC.1401.735). Findings will be disseminated through publication in a peer-reviewed journal and presentations at relevant conferences. TRIAL REGISTRATION NUMBER: IRCT20100414003706N42.

RESUMEN

INTRODUCTION: Older adults in care homes experienced some of the highest rates of mortality from SARS-CoV-2 globally and were subjected to strict and lengthy non-pharmaceutical interventions, which severely impacted their daily lives. The VIVALDI ASCOT and Ethnography Study aims to assess the impact of respiratory outbreaks on care home residents' quality of life, psychological well-being, loneliness, functional ability and use of space. This study is linked to the VIVALDI-CT, a randomised controlled trial of staff's asymptomatic testing and sickness payment support in care homes (ISRCTN13296529). METHODS AND ANALYSIS: This is a mixed-methods, longitudinal study of care home residents (65+) in Southeast England. Group 1-exposed includes residents from care homes with a recent COVID-19 or other respiratory infection outbreak. Group 2-non-exposed includes residents from care homes without a recent outbreak. The study has two components: (a) a mixed-methods longitudinal face-to-face interviews with 100 residents (n=50 from group 1 and n=50 from group 2) to assess the impact of outbreaks on residents' quality of life, psychological well-being, loneliness, functional ability and use of space at time 1 (study baseline) and time 2 (at 3-4 weeks after the first visit); (b) ethnographic observations in communal spaces of up to 10 care homes to understand how outbreaks and related restrictions to the use of space and social activities impact residents' well-being. The study will interview only care home residents who have the mental capacity to consent. Data will be compared and integrated to gain a more comprehensive understanding of the impact of outbreaks on residents' quality of life and well-being. ETHICS AND DISSEMINATION: The VIVALDI ASCOT and Ethnography Study obtained ethical approval from the Health Research Authority (HRA) Social Care REC (24/IEC08/0001). Only residents with the capacity to consent will be included in the study. Findings will be published in scientific journals.

RESUMEN

BACKGROUND: Diabetes increases the risk of psychosocial health problems. Person-centred psychosocial care is therefore advocated. However, several barriers to implementation exist, including uncertainty about how to approach psychosocial problems in consultations. OBJECTIVE: We aimed to explore which psychosocial outcomes patients and healthcare professionals consider important and whether certain characteristics are associated with this. We propose strategies for facilitating psychosocial diabetes care on this basis. METHODS: The results of an international Delphi study aimed at achieving multi-stakeholder consensus on a diabetes outcome set were analysed. We compared the importance ratings of the two stakeholder groups for each psychosocial outcome. A multivariable linear regression analysis tested whether certain characteristics would predict the importance attributed to outcomes that were not generally considered important. FINDINGS: Patients and healthcare professionals agreed on the importance of regularly assessing psychological well-being, diabetes distress and diabetes-specific quality of life, while they regarded it as less important to monitor depression, anxiety, eating problems, social support and sexual health. Being a woman, younger and living with type 1 diabetes were associated with considering it important to assess eating problems. CONCLUSIONS: We propose two psychosocial care pathways that reflect the outcome preferences of patients and healthcare providers. They follow a stepped approach, starting with the assessment of psychological well-being and quality of life and proceeding from there. CLINICAL IMPLICATIONS: Adopting this approach can facilitate the implementation of person-centred psychosocial diabetes care by reducing the burden and making psychosocial issues more accessible. This approach should be tested for feasibility, safety and effectiveness.

RESUMEN

QUESTION: Tricyclic antidepressants are used to treat depression worldwide, but the adverse effects have not been systematically assessed. Our objective was to assess the beneficial and harmful effects of all tricyclic antidepressants for adults with major depressive disorder. STUDY SELECTION AND ANALYSIS: We conducted a systematic review with meta-analysis and trial sequential analysis. We searched CENTRAL, MEDLINE, Embase, LILACS and other sources from inception to January 2023 for randomised clinical trials comparing tricyclic antidepressants versus placebo or 'active placebo' for adults with major depressive disorder. The primary outcomes were depressive symptoms measured on the 17-item Hamilton Depression Rating Scale (HDRS-17), serious adverse events and quality of life. The minimal important difference was defined as three points on the HDRS-17. FINDINGS: We included 103 trials randomising 10 590 participants. All results were at high risk of bias, and the certainty of the evidence was very low or low. All trials only assessed outcomes at the end of the treatment period at a maximum of 12 weeks after randomisation. Meta-analysis and trial sequential analysis showed evidence of a beneficial effect of tricyclic antidepressants compared with placebo (mean difference -3.77 HDRS-17 points; 95% CI -5.91 to -1.63; 17 trials). Meta-analysis showed evidence of a harmful effect of tricyclic antidepressants compared with placebo on serious adverse events (OR 2.78; 95% CI 2.18 to 3.55; 35 trials), but the required information size was not reached. Only 2 out of 103 trials reported on quality of life and t-tests showed no evidence of a difference. CONCLUSIONS: The long-term effects of tricyclic antidepressants and the effects on quality of life are unknown. Short-term results suggest that tricyclic antidepressants may reduce depressive symptoms while also increasing the risks of serious adverse events, but these results were based on low and very low certainty evidence.

RESUMEN

INTRODUCTION: Poverty, HIV and perinatal depression represent a triple threat to public health in sub-Saharan Africa because of their combined negative effects on parenting and child development. In the resource-constrained context of low-income and middle-income countries, a lay-counsellor-delivered intervention that combines a psychological and parenting intervention could offer the potential to mitigate the consequences of perinatal depression while also optimising scarce resources for healthcare.Measuring the cost-effectiveness of such a novel intervention will help decision-makers to better understand the relative costs and effects associated with replicating the intervention, thereby supporting evidence-based decision-making. This protocol sets out the methodological framework for analysing the cost-effectiveness of a cluster randomised controlled trial (RCT) that compares a combined intervention to enhanced standard of care when treating depressed, HIV-positive pregnant women and their infants in rural South Africa. METHODS AND ANALYSIS: This cost-effectiveness analysis (CEA) protocol complies with the Consolidated Health Economic Evaluation Reporting Standards 2022 checklist. A societal perspective will be chosen.The proposed methods will determine the cost and efficiency of implementing the intervention as per the randomised control trial protocol, as well as the cost of replicating the intervention in a non-research setting. The costs will be calculated using an appropriately adjusted version of the Standardised Early Childhood Development Costing Tool.Primary health outcomes will be used in combination with costs to determine the cost per improvement in maternal perinatal depression at 12 months postnatal and the cost per improvement in child cognitive development at 24 months of age. To facilitate priority setting, the incremental cost-effectiveness ratios for improvements in child cognitive development will be ranked against six other child cognitive-development interventions according to Verguet et al's methodology (2022).A combination of activity-based and ingredient-based costing approaches will be used to identify, measure and value activities and inputs for all alternatives. Outcomes data will be sourced from the RCT team. ETHICS AND DISSEMINATION: The University of Oxford is the sponsor of the CEA. Ethics approval has been obtained from the Human Sciences Research Council (HSRC, #REC 5/23/08/17), South Africa and the Oxford Tropical Research Ethics Committee (OxTREC #31-17), UK.Consent for publication is not applicable since no participant data are used in this protocol.We plan to disseminate the CEA results to key policymakers and researchers in the form of a policy brief, meetings and academic papers. TRIAL REGISTRATION DETAILS: ISRCTN registry #11 284 870 (14/11/2017) and SANCTR DOH-27-102020-9097 (17/11/2017).

RESUMEN

INTRODUCTION: Traumatic brain injury (TBI) is a major cause of disability, with annual global incidence estimated as 69 million people. Survivors can experience long-term visual changes, altered mental state, neurological deficits and long-term effects that may be associated with mental illness. TBI is prevalent in military personnel due to gunshot wounds, and blast injury. This study aims to evaluate the relationship between evolving visual, biochemical and mental health changes in both military veterans and civilians, suffering from TBI, and detect preliminary indicators of prognosis for TBI recovery, and quality-of-life outcomes. METHODS AND ANALYSIS: UNTANGLE is a 24-month prospective observational pilot study recruiting three patient groups: civilians with acute moderate-severe TBI, military veterans with diagnosis of a previous TBI and a control group of civilians or veterans with no history of a previous TBI. Patients will undergo visual, biochemical and mental health assessments, as well as patient-reported quality of life outcome measures over the course of a 1-year follow-up period. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Health Research Authority and Health and Care Research Wales with a REC reference number of 23/NW/0203. The results of the study will be presented at scientific meetings and published in peer-reviewed journals, including both civilian and military-related publications. We will also present our findings at national and international meetings of learnt neuroscience and neuropsychiatry and military societies. We anticipate that our pilot study will inform a larger study on the long-term outcomes of TBI and quality of life, specific to military veterans, such that potential interventions may be accessed as quickly as possible.

RESUMEN

OBJECTIVE: To determine the prevalence and factors associated with anxiety and depression and the care-seeking behaviour among Nepalese population. DESIGN AND SETTINGS: Secondary analysis of the data from nationally representative Nepal Demographic and Health Survey 2022. PARTICIPANTS: Analysed data of 12 355 participants (7442 females and 4913 males) aged 15-49 years. OUTCOME MEASURES: Depression and anxiety were assessed using Patient Health Questionnaire-9 (PHQ-9) and Generalised Anxiety Disorder Assessment (GAD-7) tools, respectively. STATISTICAL ANALYSIS: We performed weighted analysis to account for the complex survey design. We presented categorical variables as frequency, per cent and 95% confidence interval (CI), whereas numerical variables were presented as median, inter-quartile range (IQR) and 95% CI. We performed univariate and multivariable logistic regression to determine factors associated with anxiety and depression, and results were presented as crude OR (COR), adjusted OR (AOR) and their 95% CI. RESULTS: The prevalence of depression and anxiety were 4.0% (95% CI 3.5 to 4.5) and 17.7% (95% CI 16.5 to 18.9), respectively. Divorced or separated participants were found to have higher odds of developing anxiety (AOR 2.40, 95% CI 1.74 to 3.31) and depression (AOR 3.16, 95% CI 1.84 to 5.42). Among ethnic groups, Janajati had lower odds of developing anxiety (AOR 0.77, 95% CI 0.65 to 0.92) and depression (AOR 0.67, 95% CI 0.49 to 0.93) compared with Brahmin/Chhetri. Regarding disability, participants with some difficulty had higher odds of developing anxiety (AOR 1.81, 95% CI 1.56 to 2.10) and depression (AOR 1.94, 95% CI 1.51 to 2.49), and those with a lot of difficulty had higher odds of anxiety (AOR 2.09, 95% CI 1.48 to 2.96) and depression (AOR 2.04, 95% CI 1.06 to 3.90) compared with those without any disability. Among those who had symptoms of anxiety or depression, only 32.9% (95% CI 30.4 to 34.4) sought help for the conditions. CONCLUSIONS: Marital status and disability status were positively associated with anxiety and depression, whereas Janajati ethnicity had relatively lower odds of experiencing anxiety and depression. It is essential to develop interventions and policies targeting females and divorced individuals to help reduce the burden of anxiety and depression in Nepal.

RESUMEN

INTRODUCTION: Postpartum anaemia is often caused by iron deficiency with onset during the antepartum period and can be exacerbated by excessive blood loss at birth. Its prevalence is estimated as 50-80% in low-income and middle-income countries. It poses adverse consequences on the mother and negatively impacts her ability to care for her newborn. Prompt treatment of postpartum anaemia is thus important. Adherence to oral iron is reportedly low in Nigeria due to its side effects and forgetfulness by the mothers. Intravenous iron such as ferric carboxymaltose, given as a single dose, might help overcome adherence issues, but investigation in a high-quality randomised control trial in Nigeria is first required while evaluation of challenges around its implementation is also warranted. OBJECTIVE: To determine the clinical effectiveness, tolerability and safety, of using intravenous ferric carboxymaltose (intervention) vs oral ferrous sulphate (control) for treating moderate to severe iron deficiency anaemia in postpartum women and to evaluate implementation of ferric carboxymaltose in treating postpartum anaemia in Nigeria. METHODS AND ANALYSIS: This study is an open-label randomised controlled trial with a concurrent implementation study. It is a hybrid type 1 effectiveness-implementation design conducted in four states across Northern and Southern Nigeria. A total of 1400 eligible and consenting women with postpartum moderate to severe anaemia (haemoglobin concentration <100 g/L) will be randomised to intravenous ferric carboxymaltose; a single dose at 20 mg/kg to a maximum of 1000 mg infusion administered at enrolment (intervention) or oral ferrous sulphate; 200 mg (65 mg elemental iron) two times per day from enrolment until 6 weeks postpartum (control). The primary outcome, proportion of participants who are anaemic (Hb <110 g/L) at 6 weeks postpartum will be analysed by intention-to-treat. Haemoglobin concentration, full blood count, serum iron, serum ferritin, transferrin saturation and total iron binding capacity will be measured at specific intervals. Implementation outcomes such as acceptability and feasibility of using ferric carboxymaltose for postpartum anaemia treatment in Nigeria will be assessed. ETHICS AND DISSEMINATION: This study is approved by the ethics committee of the teaching hospitals, Ministry of Health of the four states as required, National Health Research Ethics Committee and the drug regulatory agency, National Agency for Food and Drug Administration and Control (NAFDAC). Findings of this research will be presented at conferences and will be published in international peer-reviewed journals and shared with stakeholders within and outside Nigeria. TRIAL REGISTRATION NUMBER: International standard randomised controlled trial number: ISRCTN51426226.

RESUMEN

OBJECTIVES: To evaluate the frequency and severity of depressive and anxiety symptoms and explore possible risk factors among caregivers of children with congenital ectopia lentis (CEL). DESIGN: A prospective cross-sectional study was conducted. PARTICIPANTS: 108 patients and 108 informal caregivers (mainly parents) were included. Participants were grouped based on whether patients had systemic abnormalities: group 1 were children without systemic abnormalities and group 2 were children with systemic abnormalities. OUTCOME MEASURES: The 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder Scale (GAD-7) were used to assess depressive and anxiety symptoms, respectively. RESULTS: More than half of caregivers (51.9%) have depressive or anxiety symptoms of some degree. 38.0% of caregivers suffered from both depressive and anxiety symptoms. 19.4% of caregivers had moderate to severe depressive symptoms (PHQ-9 score ≥10) while 16.7% reported moderate to severe anxiety symptoms (GAD-7 score ≥10). Between the two groups, the mean PHQ-9 and GAD-7 scores significantly differed (p=0.026 in PHQ-9; p=0.018 in GAD-7). The proportion of caregivers with moderate to severe symptoms was greater in group 2 than in group 1. In addition, there was a significant positive correlation between PHQ-9 and GAD-7 scores (r=0.827; p<0.001). Furthermore, best corrected visual acuity in the better eye of patients was positively correlated with both the PHQ-9 and GAD-7 scores (r=0.314, p<0.05 in PHQ-9; r=0.325, p<0.05 in GAD-7). CONCLUSIONS: Depressive and anxiety symptoms were common in caregivers of children with CEL, especially among those whose children had other systemic disease manifestations or low vision. This study illustrates the importance of depressive and anxiety symptom screening for these caregivers to implement effective psychological interventions and support strategies.

RESUMEN

QUESTION: Mindfulness-based programmes (MBPs) and practices have demonstrated effects in mental health and well-being, yet questions regarding the target mechanisms that drive change across the population remain unresolved. STUDY SELECTION AND ANALYSIS: Five databases were searched for randomised controlled trials that evaluate the indirect effects (IEs) of an MBP or mindfulness practice in relation to mental health and well-being outcomes through psychological mechanisms. FINDINGS: 27 eligible studies were identified, with only four exploring mechanisms in the context of specific mindfulness practices. Significant IEs were reported for mindfulness skills, decentering and attitudes of mindfulness (eg, self-compassion) across different outcomes, population samples, mental health strategies and active comparators. Evidence gap maps and requirements for testing and reporting IEs are provided to help guide future work. CONCLUSIONS: Mindfulness skills, decentering and attitudes of mindfulness may be key intervention targets for addressing the mental health of whole populations. However, future work needs to address significant knowledge gaps regarding the evidence for alternative mechanisms (eg, attention and awareness) in relation to unique outcomes (eg, well-being), mental health strategies (ie, promotion) and active comparators. High-quality trials, with powered multivariate mediation analyses that meet key requirements, will be needed to advance this area of work. TRIAL REGISTRATION NUMBER: 10.17605/OSF.IO/NY2AH.

RESUMEN

BACKGROUND: It has been reported that patients with geriatric psychiatric disorders include many cases of the prodromal stages of neurodegenerative diseases. Abnormal 123I-2ß-carbomethoxy-3ß-(4-iodophenyl)-N-(3-fluoropropyl) nortropane dopamine transporter single-photon emission computed tomography (DAT-SPECT) reveals a nigrostriatal dopaminergic deficit and is considered useful to detect dementia with Lewy bodies and Parkinson's disease as well as progressive supranuclear palsy and corticobasal degeneration. We aimed to determine the proportion of cases that are abnormal on DAT-SPECT in patients with geriatric psychiatric disorders and to identify their clinical profile. METHODS: The design is a cross-sectional study. Clinical findings of 61 inpatients aged 60 years or older who underwent DAT-SPECT and had been diagnosed with psychiatric disorders, but not neurodegenerative disease or dementia were analysed. RESULTS: 36 of 61 (59%) had abnormal results on DAT-SPECT. 54 of 61 patients who had DAT-SPECT (89%) had undergone 123I-metaiodobenzylguanidine myocardial scintigraphy (123I-MIBG scintigraphy); 12 of the 54 patients (22.2%) had abnormal findings on 123I-MIBG scintigraphy. There were no cases that were normal on DAT-SPECT and abnormal on 123I-MIBG scintigraphy. DAT-SPECT abnormalities were more frequent in patients with late-onset (55 years and older) psychiatric disorders (69.0%) and depressive disorder (75.7%), especially late-onset depressive disorder (79.3%). CONCLUSION: Patients with geriatric psychiatric disorders include many cases showing abnormalities on DAT-SPECT. It is suggested that these cases are at high risk of developing neurodegenerative diseases characterised by a dopaminergic deficit. It is possible that patients with geriatric psychiatric disorders with abnormal findings on DAT-SPECT tend to show abnormalities on DAT-SPECT first rather than on 123I-MIBG scintigraphy.

RESUMEN

BACKGROUND: Circadian rhythms influence cognitive performance which peaks in the morning for early chronotypes and evening for late chronotypes. It is unknown whether cognitive interventions are susceptible to such synchrony effects and could be optimised at certain times-of-day. OBJECTIVE: A pilot study testing whether the effectiveness of cognitive bias modification (CBM) for facial emotion processing was improved when delivered at a time-of-day that was synchronised to chronotype. METHODS: 173 healthy young adults (aged 18-25) with an early or late chronotype completed one online session of CBM training in either the morning (06:00 hours to 10:00 hours) or evening (18:00 hours to 22:00 hours). FINDINGS: Moderate evidence that participants learnt better (higher post-training balance point) when they completed CBM training in the synchronous (evening for late chronotypes, morning for early chronotypes) compared with asynchronous (morning for late chronotypes, evening for early chronotypes) condition, controlling for pre-training balance point, sleep quality and negative affect. There was also a group×condition interaction where late chronotypes learnt faster and more effectively in synchronous versus asynchronous conditions. CONCLUSIONS: Preliminary evidence that synchrony effects apply to this psychological intervention. Tailoring the delivery timing of CBM training to chronotype may optimise its effectiveness. This may be particularly important for late chronotypes who were less able to adapt to non-optimal times-of-day, possibly because they experience more social jetlag. CLINICAL IMPLICATIONS: To consider delivery timing of CBM training when administering to early and late chronotypes. This may generalise to other psychological interventions and be relevant for online interventions where the timing can be flexible.

RESUMEN

INTRODUCTION: Mental disorders are endemic. However, the mental health treatment gap remains high, especially in low-resource settings. Task-shifting is a universally recommended strategy to mitigate the care gap. The Friendship Bench (FB), a task-shifting, low-intensity psychotherapy programme founded in Zimbabwe, is effective in managing anxiety and depression. The FB programme offers clients the choice of joining add-on mental health support groups known as Circle Kubatana Tose (CKT). These groups offer an opportunity for continued psychoeducation, social support and economic strengthening. However, the evidence base for the effectiveness of add-on support groups is sparse. We hypothesise that participation in CKT is associated with increased adherence to treatment regimens, social support and well-being. This mixed-methods prospective cohort study seeks to evaluate the intermediate effects (6-month follow-up) of CKT groups, including process outcome evaluation. METHODS AND ANALYSIS: We will recruit participants (N=178) receiving mental healthcare from the FB in Harare primary care clinics. Follow-up assessments will occur at enrolment, 6 weeks, 3 months and 6 months, assessing changes in common mental disorders (depression and anxiety), social support, positive psychological indices (hope and resilience), health-related quality of life, working alliance, economic outcomes (net income) and implementation outcome (feasibility, acceptability/satisfaction and uptake of services). Quantitative data will be analysed using descriptive analysis, bivariate statistics, Cox proportional hazard models and generalised mixed models (maximum likelihood estimation). Qualitative data will be analysed using thematic analysis. DISSEMINATION AND ETHICS: Ethical approval was granted by the Medical Research Council of Zimbabwe (MRCZ/A/2427). The findings will inform the potential utility of add-on support groups in the management of anxiety and depression using task-shifting. Dissemination study outcomes will be disseminated in academic journals, social media, conferences and policy briefs.

RESUMEN

BACKGROUND: Depression in ageing adults is a public health problem. Worldwide studies have identified social and health risk factors for depressive symptoms. However, little is known about their longitudinal determinants in Mexico. OBJECTIVES AND SETTING: To find the prevalence of depressive symptoms and their longitudinal individual and contextual risk factors in Mexican adults aged 50 and older. DESIGN: Secondary data of 6460 persons aged 50 years and older from the Mexican Health and Aging Study were analysed using a 'between-within' panel data analysis approach. RESULTS: The prevalence of depressive symptoms increased from 35% in 2003 to 38% in 2015. The significantly longitudinal factors associated with these symptoms were getting older (OR 1.02, 95% CI 1.01 to 1.03), being a woman (OR 2.39, 95% CI 2.16 to 2.64), less time spent in formal education (0 years and less than 6 years OR 1.52, 95% CI 1.32 to 1.75 and OR 1.33, 95% CI 1.19 to 1.50, respectively), lower net worth (OR 1.13, 95% CI 1.08 to 1.17), being recently unemployed (OR 1.25, 95% CI 1.10 to 1.25), increased (OR 1.17, 95% CI 1.10 to 1.25) or increasing number (OR 1.23, 95% CI 1.15 to 1.31) of chronic conditions, poor (OR 4.68, 95% CI 4.26 to 5.15) or worsened (OR 1.71, 95% CI 1.61 to 1.81) self-rated health and having impairments on instrumental activities of daily living (IADLs) (OR 2.94 95% CI 2.35 to 3.67) or a new IADL impairment (OR 1.67, 95% CI 1.48 to 1.89), as well as having impairments on ADLs (OR 1.51, 95% CI 1.23 to 1.86) or a new ADL impairment (OR 1.34, 95% CI 1.21 to 1.48). CONCLUSIONS: The prevalence of depressive symptoms in Mexican adults aged 50 and older is high. Our findings show that they are longitudinally associated with the individual's demographic, socioeconomic, health and disability characteristics. Efforts in public policy should focus on preventing chronic conditions and disability, as well as fighting inequalities to reduce the prevalence of depressive symptoms.

RESUMEN

OBJECTIVES: To develop a new questionnaire for the diagnostic assessment of depression adapted to the primary care setting by combining psychiatric criteria and heuristics of general practitioners (GPs). Psychometric evaluation of the new questionnaire and first validity evidence. DESIGN: The questionnaire was developed using cognitive interviews with think-aloud technique. Factorial validity was then examined in a cross-sectional study. SETTING: Primary care. Five general practices in Bavaria, Germany. PARTICIPANTS: 15 GPs, 4 psychiatrists/psychotherapists and 13 patients participated in cognitive expert interviews. A primary care sample of N=277 consecutive patients participated in the cross-sectional study. METHODS: After consultation with experts and literature research, the questionnaire contained a self-rating part for patients and an external part for GPs. Items were then iteratively optimised using cognitive interviews. Factorial validity was examined. To estimate internal consistency, Cronbach's α was calculated. Validity was assessed by correlating the new questionnaire and the Patient Health Questionnaire-9 (PHQ-9). RESULTS: The preliminary version of the two-part 'Questionnaire for the assessment of DEpression SYmptoms in Primary Care' (DESY-PC) comprised 52 items for patients (DESY-PAT-1: questions about patient's environment; DESY-PAT-2: questions about depression-specific symptoms) and 21 items for GPs (DESY-GP). The analysis of the DESY-PAT-1 revealed a one-factor solution ('environmental factors') with Cronbach's α of 0.55. The items of the DESY-PAT-2 were assigned to three factors, 'depressive cognitions', 'suicidality' and 'symptoms of fatigue', with Cronbach's α of 0.86, 0.79 and 0.85, respectively. Factorial analysis revealed two factors for the DESY-GP: 'depression symptoms' and 'medical history/external factors'. Cronbach's α was 0.90 and 0.59, respectively. After factorial analysis, the DESY-PAT was reduced to 28 items, and the DESY-GP was reduced to 15 items. Correlations of the DESY-PC with the PHQ-9 were high and significant, indicating convergent validity. CONCLUSIONS: The new questionnaire represents an innovative extension of depression questionnaires and could be particularly suitable for general practices.
