The whole-university approach to mental health emphasises that well-being should be a strategic priority across all aspects of higher education. However, there is limited evidence on which aspects of university life institutions should target to maximise well-being.
Aim
To identify factors associated with student mental health and well-being and provide an evidence base for developing initiatives that protect and promote this.
Methods
The Nurture-U survey was conducted across five universities in the UK from 2022 to 2024. This cross-sectional sample of the survey data assessed student well-being and mental health at the start of the academic year. Hierarchical linear regression models examined the relative association between demographic, family history, university and lifestyle variables and self-reported depression, measured using the Patient Health Questionnaire-9 (PHQ-9), anxiety, measured using the Generalised Anxiety Disorder-7 (GAD-7) and well-being, measured using the Short Warwick–Edinburgh Mental Well-being Scale (SWEMWBS).
Results
A total of 14 172 students completed the survey. Over a quarter self-reported probable anxiety or depression based on established screening thresholds. Regression analysis indicated that younger age, identifying as female or lesbian, gay, bisexual, transgender, queer/questioning, intersex or asexual (LGBTQIA+) and reporting a disability were associated with poorer mental health. There was minimal evidence of mental health impact associated with university factors, such as course of study or university attended. There was a strong association with exercise and self-care.
Conclusions
We have provided evidence that exercise and self-care may be areas that universities can target when considering a whole-university approach to student mental health and well-being. Increasing opportunities for students from all backgrounds, means and abilities to adopt healthy behaviours is vital to supporting university students.
To determine the correlation between spiritual self-care practices and mindfulness among cancer patients in southeast Iran.
Methods
This descriptive, correlational, cross-sectional study was conducted on a convenience sample of 600 eligible cancer patients. Data were collected using three instruments: a demographic and clinical characteristics questionnaire, the Spiritual Self-Care Practice Scale, and the Relaxation, Meditation, and Mindfulness Trait Tracker (RMMtm 3.1). Data were analyzed using SPSS version 26, employing both descriptive and inferential statistical methods, including multivariate regression analysis.
Results
The mean total score for spiritual self-care practice among cancer patients was 3.17 ± 1.15, which was above the questionnaire’s midpoint. Mindful emotion had the highest mean score (3.78 ± 1.67), followed by mindful focus (3.20 ± 1.57) and mindful relaxation (3.14 ± 1.65). Multivariate regression analysis revealed that 63.9% of the variance in spiritual self-care was explained by variables including mindful emotion (β = 0.321, p < 0.001, 95% confidence interval [CI]: [0.122, 0.181]), mindful quiet (β = 0.213, p < 0.001, 95% CI: [0.065, 0.128]), and mindful transcendence (β = 0.163, p < 0.001, 95% CI [0.058, 0.139]). Income level, history of underlying disease, and disease stage also showed significant associations.
Significance of the results
The study findings indicate a significant relationship between spiritual self-care practice and dimensions of mindfulness. Nurses can address patients’ spiritual self-care practice needs by implementing the nursing process and empowering them through interventions that enhance mindfulness.
This analysis aimed to examine past 20-year prevalence trends of multiple mental health outcomes by age and sex, using repeated cross-sectional survey data from the Canadian household population.
Methods
Age- and sex-stratified bootstrap-weighted prevalence estimates were calculated from available Canadian Community Health Survey datasets between 2002 and 2024. Categorizations for age included adolescents and young adults (12–29 years), middle-aged adults (30–64 years) and older adults (65+ years). Mental health outcomes included self-reported professionally diagnosed mood and anxiety disorder, depression survey scales (Composite International Diagnostic Interview Short Form for Major Depression /9-item brief Patient Health Questionnaire) and fair/poor self-perceived mental health. Stratified prevalence estimates from each year were combined and assessed for heterogeneity using random-effects meta-analysis. In the instance of heterogeneity, meta-regression models were applied to generate predicted prevalence trends over time for each mental health outcome, by age and sex categories.
Results
The prevalence of all mental health outcomes increased from 2002/2003 to 2024, in all age groups of both sexes. For example, in adolescent and young adult males, the weighted prevalence of diagnosed mood disorder increased from 2.37% (95% confidence interval [CI]: 2.03, 2.78) in 2003 to 12.58% (95% CI: 10.37, 15.19) in 2024, while prevalence in females of this age group increased from 5.23% (95% CI: 4.76, 5.74) in 2003 to 21.49% (95% CI: 18.97, 24.24) in 2024. Generally, young males saw the greatest relative increases in prevalence, while young females had the greatest absolute increases. Middle-aged and older adults also saw notable increases in their prevalence of poor mental health. Quadratic survey year terms were statistically significant in meta-regression analysis for all outcomes, age and sex groups (excluding mood disorder trends in65+-year-old adults), suggesting curvilinear trends. Male age categories showed more similar trends over time when compared to age-specific estimates of females.
Conclusions
The broad identification of increasing prevalence across various outcomes, age and sex groups has not been highlighted by prior research. Though prevalence increases in young females remain distinct, this finding aligns with previous literature. Consistency of trend patterns between diverse mental health outcomes indicates that multiple dimensions of mental health may be changing similarly over time. Future analyses are critical in understanding the potential factors contributing to these trends and should look to include broad population samples, rather than limiting analyses to specific age/sex groups.
Aristotle had a decisive impact on the development of ancient medicine. He and his followers conducted a dialogue about life and living beings, body and soul, and health and disease with doctors from the Classical period down to late antiquity: interlocutors who included key figures like Galen and the Hippocratic commentator Stephanus of Alexandria. Philip van der Eijk's magisterial and attractively written book describes and analyses this dialogue and argues that Aristotle strategically positioned himself within these discussions while making important and innovative contributions to them. The author further uncovers unpublished evidence showing how Aristotle's philosophy itself – and also the way it was elaborated by its later advocates and exegetes – was influenced by its close engagement with medical theory and practice. This important and much-anticipated book will transform both the study of Aristotle and his followers and that of Greek and Roman medicine.
Cross-cultural supervision (CCS) in mental health and psychosocial support (MHPSS) services occurs when supervisors and supervisees are from different cultures or contexts. In CCS, cultural differences intersect with supervisory power asymmetries, making supervisees vulnerable to culturally unsafe supervision practices. Despite CCS becoming more common in MHPSS, there remains limited understanding of how to practice culturally safe supervision. Further, this growing literature has not been synthesised. This scoping review explores how and by whom CCS is framed, what processes are involved, and how CCS may support MHPSS services, guided by an epistemic injustice framework. The search of academic and grey literature identified 45 papers on CCS in MHPSS. Most CCS studies were based in Western Educated Industrial Rich and Democratic (WEIRD) countries and used WEIRD paradigms, raising questions about generalisability and culturally safe application of CCS in non-WEIRD contexts. Studies in WEIRD countries often framed CCS using ethnocentric language, and inconsistent terminology when discussing culture. There was also a wide range of types of cross-cultural supervisory relationships, which we conceptualised as a broad spectrum whereby supervisory relationships differ in the extent of cultural difference between supervisors and supervisees. Common factors addressed in CCS literature were supportive relational processes, challenges in communication, culturally responsive practices and power dynamics. Culturally responsive supervision occurs through supervisor cultural humility, self-reflection on power, reciprocal learning attitudes and supervisors encouraging multicultural discussions. Culturally safe supervision benefits MHPSS services through enhanced supervisee clinical skills, increasing disclosures of client case information, increasing cultural humility and adapting Western models of therapy to suit clients. Based on these findings, we recommend that researchers and practitioners: acknowledge WEIRD paradigm dominance and White normativity; seek definitional clarity of CCS concepts; initiate supervisor-led multicultural discussions that recognise power dynamics; practice cultural humility; proactively seek peer and supervisor support; prioritise locally-led supervision and education research in non-WEIRD and humanitarian settings; and develop new models of CCS processes and configurations. This review has implications for CCS practice and research, raising questions about the underrepresentation of non-WEIRD scholarship and privileging of WEIRD paradigms, and highlighting a need for development of epistemically just and culturally safe CCS models.
In Chapter 1, human well-being is defined and compared globally as inherently relational and creative, based on current research, indicating that the impact of technology is causing societal and individual stress, particularly due to social isolation.
In Somalia, a treatment gap exceeding 80% reflects the combined effects of supernatural explanatory models, multi-level stigma and a critically under-resourced mental health system. Misconceptions framing psychiatric illness as jinn possession, divine punishment or medication-induced harm are pervasive and clinically consequential, driving delayed presentation, treatment refusal and nonadherence. Stigma operates simultaneously at individual, family and community levels, each reinforcing the other. This Perspective, grounded in clinical observations from outpatient psychiatric practice in Mogadishu, describes these patterns, situates them within published evidence and proposes actionable, feasible responses: culturally adapted community education, structured psychoeducation as a mandatory clinical step, anti-stigma programming, primary care integration using the WHO mhGAP framework, task-shifting and family-inclusive care. The effectiveness of these interventions must be tested through locally led implementation research.
Youths experience mental health challenges which are associated with their biopsychosocial development. However, this has been exacerbated by technological advances and their attendant challenges. Therefore, there is a need to periodically screen youths’ mental health using psychometrically valid scales so as to offer appropriate preventive and interventional programmes for them. This study examined the preliminary psychometric properties of eight mental health scales and their relationships among youths in Hong Kong. A total of 428 youths were conveniently recruited to respond to measures on depression, anxiety, somatic symptoms, smartphone application-based addiction, obsessive–compulsive symptoms, internet addiction, insomnia, life satisfaction, stress and cognitive fatigue. Data were analysed using Confirmatory factor analysis (CFA) and Pearson’s r. Generally, CFA fits (comparative fit index >0.9, Tucker–Lewis index >0.9, root mean square error of approximation <0.08 and standardised root mean square residual <0.08), average variance extracted (ranging between 0.531 and 0.724), composite reliability (ranging between 0.875 and 0.946) and internal reliability (Cronbach’s α = 0.834–0.918 and McDonald’s ω = 0.860–0.925) for the scales were acceptable. Correlations were significant among all measures (ps < 0.001). The CFA indices and correlational analyses suggest that all eight mental health measures have acceptable reliability and construct–convergent validity. Health and research professionals can use these scales to promote mental health activities among youths in Hong Kong.
Bede (“river gypsy”) communities in Bangladesh live with recurrent flooding, riverbank erosion, and displacement, alongside entrenched stigma and service exclusion, placing them at high risk of climate-related mental distress. We conducted a hermeneutic phenomenological study to examine how environmental hazards, social exclusion, and access barriers affect mental health and coping among Bede communities living along the Jamuna River in Sirajganj district. Seven in-depth interviews and one focus group discussion were carried out with adult community members. Data were analysed using reflexive thematic analysis, informed by Conservation of Resources (COR) theory, structural stigma theory, and a patient-centred access framework. Four interconnected domains were identified. First, environmental shocks and resource loss: hydro-climatic events (flooding, erosion, forced moves) triggered cumulative losses of shelter, assets, income, and schooling (hydro-climatic shocks → resource loss → demoralisation; COR loss spiral). Second, sleep disruption and persistent arousal: unsafe, damp sleeping spaces and anticipatory fear of future floods generated chronic insomnia, fatigue, and irritability (resource loss → unsafe sleep → persistent arousal). Third, gatekeeping and structural exclusion: stigmatising labels, lack of fixed address and documentation led to denial of water, exclusion from relief and social protection, and humiliating encounters in services (structural gatekeeping → disrupted ability to seek, reach and engage with care). Fourth, coping repertoires and collective strategies: prayer, quiet reflection, family pooling of resources, community solidarity, and pluralistic help-seeking from biomedical and traditional healers provided important but fragile buffers. Mental distress among Bede communities arises from the interaction of cumulative resource loss, sleep disruption and structural exclusion. Disaster-risk-reduction and health policies for mobile, climate-vulnerable populations should secure safe dry sleeping spaces, lighting, food and small assets; introduce portable ID and flexible registration; implement low-threshold, co-designed mental health and psychosocial support through outreach-based primary care; and reduce stigma at initial point of contact.
This study aims to examine the longitudinal associations between work–family conflict (WFC) and mental health among working parents. Specifically, we investigated whether within-person changes in WFC and family-to-work conflict (FWC) are associated with changes in mental health.
Methods
Data from the Household, Income and Labour Dynamics in Australia survey were used to employ within-person fixed effects regression analysis to examine associations between WFC and mental health in working-age adults (18–64 years) with parental responsibilities for children ≤14 years. The outcome, general mental health and overall psychological well-being, was assessed using the Mental Health Inventory-5 scale as a continuous variable with scores ranging from 0 to 100. Both dimensions of WFC, measured as continuous variables ranging from 1 to 7 with higher scores indicative of greater conflict (work-to-family and family-to-work), were interrogated, as were gender differences. Exposures, outcome and covariates were assessed repeatedly across the 21-year follow-up period.
Results
A total of 7,265 participants (46,564 observations) across waves 2001–2021 who were working-age parents engaged in paid employment with children ≤14 years, with at least two waves of data and non-missing data were included in the analyses. Mean (SD) duration of follow-up was 6.1 (3.7) years and 6.7 (4.2) years for mothers and fathers, respectively. A total of 49.6% of participants were female, and the mean baseline age was 35 years for both mothers and fathers. Increasing WFC was negatively associated with mental health in women (β coefficient = −1.25 [95% CI: −1.45, −1.05]) and men (β coefficient = −1.21 [95% CI: −1.40, −1.02]). Increasing FWC was associated with worse mental health in women (β coefficient = −1.09 [95% CI: −1.33, −0.85]) and men (β coefficient = −1.51 [95% CI: −1.75, −1.28]).
Conclusions
Changes in both WFC and FWC over time are associated with changes in mental health for women and men. More attention needs to be devoted to identifying and implementing strategies to enable working parents to cope with or reduce WFC.
Adolescent mothers in forced displacement experience intersecting risks related to adolescent development, displacement-related traumatic experiences and early motherhood. Despite these risks, their mental health needs remain understudied in humanitarian research and policy. This narrative review synthesizes evidence from conflict-affected settings. Drawing on literature published between 2000 and 2025, we propose the Triple Jeopardy Framework, a conceptual model describing how adolescence, forced displacement and motherhood interact to influence mental health outcomes, including depression, anxiety, post-traumatic stress disorder and intergenerational mental health risk. The framework distinguishes the separate risk and protective factors associated with each area, then shows how their intersections can create synergistic risk by weakening protective systems, limiting access to care and increasing psychological distress. At the same time, displaced adolescent mothers may exercise agency and draw meaning from motherhood while also experiencing significant distress and constraint. Effective responses require interventions that address structural determinants, strengthen community-based support systems, integrate maternal and mental health care and remain responsive to young mothers’ capabilities and caregiving realities. The Triple Jeopardy Framework provides a basis for developing gender-responsive, life-course approaches to adolescent maternal mental health in humanitarian settings.
Psychosocial factors represent modifiable targets relevant to alleviate depression risk. While individual psychosocial risks are well-documented, their combined status across multiple life domains is underexplored. We aimed to construct a novel multidimensional composite score of psychosocial status and explore its association with incidence of depression.
Methods
A total of 336,922 individuals (mean age 56.21 years) without depression at baseline from the UK Biobank were included. Psychosocial status was assessed across four dimensions (recent stressful events, current psychiatric symptoms, social contact and socio-economic status) using 18 factors. A composite psychosocial score was constructed by weight effect of each factor, with higher values indicating lower level of psychosocial status. Using Cox proportional hazards models to evaluate the associations between individual psychosocial factor, psychosocial score and the risk of depression.
Results
During a median follow-up of 13.60 years, 14,806 depression cases were identified. Low household income, recent depressive symptoms, loneliness and financial difficulties emerged as the most significant predictors of depression across four domains, with hazard ratios (HRs) of 3.82 (95% confidence intervals [CIs]: 3.43–4.26), 3.09 (2.99–3.19), 2.46 (2.37–2.54) and 1.96 (1.88–2.04), respectively. Each one-point increase in the psychosocial score was associated with a 42% higher depression risk. Compared to individuals with high psychosocial status, those in the medium- and low-level groups had an adjusted HR of 1.71 (95% CI: 1.62–1.81) and 4.36 (95% CI: 4.15–4.58), respectively.
Conclusions
These findings highlight that psychosocial factors collectively represent modifiable targets for preventing depression, with interventions addressing the combined status of these domains likely offering greater impact than focusing on isolated factors.
Disclosure of a mental health problem carries both risks and benefits. It can be seen as a measure of perceptions of the social environment in which people with mental health problems live, work and study. A nationally representative Australian survey conducted in 2014 showed that, in many settings, non-disclosure was more common than disclosure. This study aimed to investigate whether disclosure in a broad range of settings has changed since the 2014 national survey.
Methods
Large nationally representative surveys of Australian adults were conducted in 2014 and 2024. For each, those who reported a mental health problem or were experiencing high psychological distress (n = 1381 in 2014, n = 2613 in 2024) were asked about disclosure in multiple settings. Regression analyses were used to explore whether changes between survey years were significant at p < 0.01, adjusting for sociodemographic variables of age, gender, education level, language spoken at home, country of birth and type of mental health problem. Secondary analyses assessed the sociodemographic and mental health problem characteristics associated with changes.
Results
In 2024, participants were less likely than in 2014 to have disclosed to friends, partners, family members and some people in the neighbourhood, with relative risk ratios (RRRs) ranging from 0.33 (99% confidence interval [CI]: 0.23, 0.48; p < 0.001) for all family members to 0.64 (99% CI: 0.46, 0.88; p < 0.001) for some people in the neighbourhood. Workplace disclosure did not change significantly. For health professionals not involved in mental health treatment, the RRRs of disclosure were higher in 2024 than in 2014 (RRR = 1.56 [99% CI: 1.16, 2.10; p < 0.001] for disclosure to some and RRR = 2.31 [99% CI: 1.61, 3.32; p < 0.001] for disclosure to all).
Conclusions
Except for disclosure to health professionals not involved in mental health treatment, there have been decreases or no changes in disclosure of a mental health problem in most settings over the last 10 years. This likely reflects both perceptions of, and actual, reductions in supportive social environments. Urgent action is needed to ensure that, for people who do disclose a mental health problem, the benefits strongly outweigh the risks.
The ongoing conflict in Sudan, which began in April 2023, has triggered a severe but under-recognized mental health crisis. Nearly two-thirds of hospitals in conflict-affected regions are non-functional, supply chains have collapsed, and fewer than 100 psychiatrists serve a population of 45 million. Emerging evidence documents rates of post-traumatic stress disorder, depression, and anxiety among displaced and non-displaced civilians, children, and health workers, yet mental health remains systematically neglected in humanitarian response. This commentary examines the gap between global commitments—including the Sustainable Development Goals and WHO’s Mental Health Gap Action Programme (mhGAP)—and the realities of care in conflict settings. Drawing on lessons from Syria, Yemen, and Ukraine, we outline a 6-priority framework for immediate mental health integration: (1) training lay health workers for task-shifted psychological support; (2) rebuilding essential psychiatric infrastructure; (3) establishing protected humanitarian corridors for psychotropic medications; (4) expanding tele-psychiatry and remote counselling; (5) integrating mental health into primary and emergency care; and (6) addressing stigma through community engagement. We argue that without explicit funding allocations and operational mandates for mental health services, post-conflict recovery and peacebuilding in Sudan will remain compromised. We call on donors to allocate at least 10% of health-related humanitarian aid to mental health initiatives and for WHO and UNICEF to embed mhGAP in all emergency responses. Sudan represents both an urgent crisis and a global warning: mental health can no longer remain the invisible dimension of humanitarian emergencies.
The COVID-19 pandemic is often portrayed as a universal mental health crisis, especially in studies lacking pre-pandemic data. Research including pre-pandemic assessments nonetheless yields mixed results, making the pandemic’s impact unclear, particularly when considering differences between general and clinical populations (defined as individuals with prior mental disorder diagnoses). This study examined depression and anxiety trajectories from pre-pandemic to pandemic phases in general and clinical populations. It also explored how symptom trajectories varied by sociodemographic and pandemic-related factors.
Methods
In the current study, we drew on three general-population cohorts from Germany and France (n = 1,813) that had previously been harmonized within the Co-RESPOND project. We additionally harmonized and integrated three clinical cohorts from the Netherlands (n = 1,069) into this pooled dataset. Cohorts were included in the present study if they provided pre-pandemic baseline data and at least two assessments during the pandemic. Anxiety and depressive symptoms were measured using validated instruments and transformed into z-scores to enable cross-cohort comparability. Symptom trajectories were identified separately for general-population and clinical cohorts using latent growth mixture modelling, and logistic regressions were used to examine factors associated with trajectory membership.
Results
Participants in the general-population sample had a median age of 39.8 years, while those in the clinical sample had a median age of 57.4 years. Women accounted for 64.6% of the general-population group and 67% of the clinical group. In the general population, approximately 80% showed decreasing symptoms, including those with higher initial severity, while 20% maintained low levels. Divorce/separation and having children were related to more favourable anxiety and depression trajectories, while older age and childcare burden were associated with less favourable trajectories of depressive symptoms. In the clinical population, approximately half improved from moderate symptom levels, with the remainder exhibiting consistently high or low symptoms. Being in a relationship, older age and being a man were linked to more favourable anxiety trajectories.
Conclusions
This study provides substantial evidence that the COVID-19 pandemic did not lead to a uniform deterioration in mental health, as most adults across both general and clinical populations experienced stable or improving symptoms. Our findings underscore the need for mental health surveillance and differentiated, proportionate responses that reflect diverse symptom patterns and risk profiles.
South Korea has one of the highest suicide rates among Organisation for Economic Co-operation and Development countries, and lower happiness has been associated with suicidal ideation and suicide attempts in Korean populations. We aimed to estimate a nation-level item network of happiness, affect, personality and well-being evaluations in South Korea and to test whether this network differed by sex, income and generation.
Methods
We analysed 2020–2023 Korean Happiness Survey data from 64,531 respondents in South Korea; the network analyses used 61,675 complete cases. A Gaussian graphical model with Least Absolute Shrinkage and Selection Operator regularization estimated edges among happiness, affect, personality and well-being evaluations. Subgroup differences by sex, income and generation were assessed with permutation-based Network Comparison Tests.
Results
The network contained 199 of 435 possible edges (45.7%). The strongest affective and happiness-related pairwise connections included happiness-enjoyment, stress-tiredness, sadness-depression and depression-anger. Global strength did not differ significantly across the planned subgroup comparisons, but network structure differed by sex, income, Millennials and Generation Z (MZ) versus Generation X, and MZ versus Baby Boomers. In the income comparison, happiness was more negatively linked to the agreeableness item ‘generally trusting’ in the low-income network, whereas its link with time for hobbies was stronger in the high-income network. In the generational comparison, the happiness-stress edge differed between the MZ generation and Baby Boomers, whereas no happiness-connected edge survived false discovery rate correction for MZ versus Generation X. No happiness-connected edge differed significantly by sex.
Conclusions
In South Korea, happiness was most closely linked to enjoyment and embedded within tightly connected affective and evaluative domains. The subgroup differences were selective rather than global, suggesting that future work relevant to population well-being and suicide prevention may benefit from focusing on specific happiness-linked domains such as positive affect, stress-related ties, discretionary time and perceived future security.
‘Engaging’ well in psychological therapy is generally associated with more positive clinical outcomes. However, the literature shows little agreement on how to define, conceptualise and measure engagement. Few studies focus primarily on engagement, and those that include engagement measures within other designs rely mainly on single behavioural indicators, such as whether between-session tasks (e.g. ‘homework’ in cognitive behavioural therapy) were completed, or the number of sessions attended. Although pragmatic, I suggest these indicators do not capture the full sense of what engagement means and that taking a broader perspective is likely to be helpful in advancing research and clinical practice. I present a conceptual model of engagement in psychological therapy that aims to draw together relevant theoretical ideas and combine them with observations from clinical practice. This proposes that engagement can be understood as three distinct facets: engagement with the therapist, engagement with the therapy approach, and the practical, behavioural indicators of engagement. I suggest this offers a comprehensive way to conceptualise and understand engagement that may prove helpful for clinicians and researchers. I aim to advocate for further research in this area and for applying the ‘empirically grounded clinical interventions’ approach to therapy processes, not just therapy content. This could help further our understanding of the engagement process, which may play a critical role in driving successful therapy outcomes.
Machine learning is increasingly reshaping psychological and mental health research by complementing traditional theory-driven approaches with data-driven predictive modelling. This encompasses three key transitions: from hypothesis-testing to pattern discovery; from controlled experimental settings to naturalistic and multidimensional data ecosystems; and from explanatory theoretical models to prediction-informed theory-building and clinical translation. Nevertheless, this methodological reorientation remains insufficiently synthesised. Our aim is to examine how machine learning is reshaping psychological research methodologies, focusing on its ability to process and analyse multidimensional data, its capacity to model complex associations and temporal patterns and its integration into clinical practice. We critically examine both the opportunities and boundaries of integrating predictive models with theoretical insights. We further clarify that predictive accuracy, interpretability and causal explanation are related but distinct aims, and that machine learning should complement rather than replace psychological theory, causal reasoning and clinical judgement.
Children in families navigating significant adversity often face co-occurring physical and mental health problems, which together can contribute to substantial marginalization across the life course. These children and their families may greatly benefit from targeted interventions to disrupt accumulating vulnerability, which requires empirical evidence on the underlying dynamics of adversity and health problems throughout childhood.
Methods
We investigated associations between childhood adversities (material deprivation, experiences of loss or threat of loss, and family dynamics) and hospitalizations for mental and physical health problems across four developmental periods among 11,978 children who experienced high rates of family adversity. We used data from the Danish Life Course (DANLIFE) register-based cohort study and applied cross-lagged networks models. Hospitalizations were identified through inpatient, outpatient, and emergency hospital contacts.
Results
We found clear evidence of reciprocal associations between childhood adversities and physical and mental health problems across childhood, alongside strong autoregressive effects within adversity and health domains, indicating vicious circles of reinforcing vulnerability. Conditional on high health problems in infancy, childhood adversity was not found to be associated with additional health problems throughout the rest of childhood. Child health problems were, however, positively associated with subsequent adversity across childhood.
Conclusions
Dynamics of childhood adversity and poor health give rise to complex reinforcing patterns of vulnerability over time. Our findings contribute to a better understanding of the emergence of vulnerability resulting from childhood adversity and poor health in children, highlighting the importance of embracing the complex nature of these emergent phenomena, both in research and intervention.
Although a relationship between body fat and mental health problems has been established, sex-based differences in this association remain insufficiently understood.
Aims
To investigate the association of whole-body and regional fat mass indices with anxiety symptoms in men and women.
Method
A nationwide sample of 3856 men and 5010 women was analysed. Fat mass of the whole body, trunk, arm and leg was measured using a bioelectrical impedance analyser, and fat mass indices (kg/m2) were derived by dividing fat mass by height squared. Symptoms of anxiety were determined using the Generalized Anxiety Disorder-7. Logistic regressions were used to investigate the association of each fat mass index with anxiety symptoms. Sex-stratified analyses were conducted to assess sex-related differences.
Results
The prevalence of anxiety symptoms was 3.3% among men and 5.5% among women. Among female participants, a one-standard deviation increase in whole-body, trunk, arm or leg fat mass index was associated with 1.20-fold (95% CI: 1.04–1.39), 1.21-fold (95% CI: 1.04–1.41), 1.19-fold (95% CI: 1.04–1.35) and 1.19-fold (95% CI: 1.03–1.38) increases in odds of anxiety symptoms, respectively. By contrast, no clear association was observed between fat mass indices and anxiety symptoms in men.
Conclusions
Our analysis demonstrated sex differences in the relationship between body fat and anxiety, with high whole-body and regional fat mass indices positively associated with anxiety symptoms in women.
