Yu JJ, Zhang Z. Long-term impact of adverse childhood experiences and perceived social support on depression trajectories. J Affect Disord 2024; 369:255-264. [PMID: 39341289 DOI: 10.1016/j.jad.2024.09.170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 09/21/2024] [Accepted: 09/25/2024] [Indexed: 09/30/2024]
Abstract
BACKGROUND While the impact of adverse childhood experiences (ACEs) on depression is well-documented, how ACEs, physical violence victimization, social support, and school belongingness altogether shape depression from adolescence to young adulthood remains unclear. This study aims to clarify these relations by tracing the trajectory of depression across this critical developmental period. METHODS We utilized a 14-year, four-wave dataset from the National Longitudinal Study of Adolescent to Adult Health (Add Health), including 5734 participants who were 7th to 12th graders at baseline (51.4 % females). Latent growth curve modeling (LGCM) was used to analyze the trajectory of depression from adolescence to young adulthood, assessing the impact of ACEs, physical violence victimization, social support, and school belongingness on this progression. RESULTS Results from the LGCM indicated that childhood maltreatment and physical violence victimization were positively associated with an increase in depression from adolescence to young adulthood. Conversely, social support and school belongingness showed a negative association with depression, indicating their protective effects over time. Gender was found to moderate these longitudinal associations, with females showing increased vulnerability to the negative relations between early stressful environments (i.e., childhood maltreatment and physical violence victimization) and depression. Conversely, they seemed to benefit more from school belongingness and social support in mitigating depression. LIMITATIONS The study variables were all self-reported and exhibited some issues with reliability. CONCLUSION Practitioners should implement gender-specific programs for the prevention and intervention of depression from adolescence through young adulthood.

Abstract
BACKGROUND Limited knowledge exists regarding the effectiveness of aquatic exercise intervention for improving executive function (EF) in children with autism spectrum disorder (ASD). Additionally, the impact of aquatic exercise on brain-derived neurotrophic factor (BDNF) in children with ASD requires further investigation. AIMS This study aimed to explore the effects of a 12-week aquatic exercise intervention on core EF and BDNF levels in children with ASD. METHODS AND PROCEDURES Thirty children with ASD were assigned to an experimental or control group. The experimental group underwent a 12-week aquatic exercise intervention, while the control group engaged in supervised free activities. Pre- and post-intervention assessments measured EF and BDNF levels. OUTCOMES AND RESULTS The experimental group showed significant improvements (p < 0.05) in inhibition control, cognitive flexibility, and BDNF levels. However, working memory did not significantly improve. The control group exhibited no significant changes in EF or BDNF levels. CONCLUSIONS AND IMPLICATIONS Aquatic exercise appears to be a beneficial intervention for cognitive development in children with ASD, as it enhances inhibition control, cognitive flexibility, and BDNF levels in children with ASD. Furthermore, the observed improvements in EF following aquatic exercise intervention in children with ASD may be associated with increased BDNF levels.

Lonely and scrolling during the COVID-19 pandemic: understanding the problematic social media use and mental health link among university students. Front Psychiatry 2024; 15:1247807. [PMID: 38356913 PMCID: PMC10864490 DOI: 10.3389/fpsyt.2024.1247807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 01/10/2024] [Indexed: 02/16/2024] Open
Abstract
Introduction Undergraduate university students experienced many academic and non-academic stressors during the first year of the coronavirus (COVID-19) pandemic, putting them at a greater risk of negative mental health outcomes. Reports worldwide have shown high incidences of depressive, anxiety, and stress scores among university students at the beginning of the pandemic. Emerging evidence also suggests that to cope with the stress and loneliness of the pandemic, many youth and young adults increased the amount of time they spent on social media platforms. Methods Undergraduate students participated in an online study aimed to understand the link between time spent on social media, coping through the use of social media and problematic social media use (PSMU) with mental health symptoms, such as stress, depression, anxiety, and loneliness, during the COVID-19 pandemic. Results While time spent on social media was only weakly associated with stress, depression, anxiety and loneliness scores, PSMU more strongly mapped onto these outcomes. Additionally, students who were coping highly using social media displayed elevated stress, depression, anxiety and loneliness levels in comparison to those reporting low levels of coping with social media. Finally, students who reported high levels of coping using social media displayed higher PSMU scores, with this relationship appearing more pronounced in students who had higher levels of loneliness. Conclusion These data support evidence that it is not necessarily time spent on social media but rather PSMU that is relevant for mental health symptoms, and that PSMU is exacerbated by loneliness. Moreover, the current results highlight the effects of maladaptive coping on mental health symptoms and PSMU among university students during the COVID-19 pandemic.

Front Psychiatry 2022; 13:892225. [PMID: 35711595 PMCID: PMC9196272 DOI: 10.3389/fpsyt.2022.892225] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/09/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Individuals requiring inpatient psychiatric care represent a group at higher risk of progressing toward suicide attempt. Using electronic medical record (EMR) data collected from psychiatric inpatient admissions, the objective of this study was to identify sex differences in risk factors for suicide plans and/or attempts within the 30 days preceding hospital admission. METHODS Resident Assessment Instrument for Mental Health (RAI-MH) intake data were obtained for patients admitted to a Canadian tertiary-care hospital deemed a "threat or danger to self" during a 10-year period (2008-2018). Data was extracted for individuals categorized into three groups: non-suicidal (N = 568), presence of suicide plan (N = 178), and presence of suspected suicide attempt (N = 124) in the 30 days prior to hospital admission. Multivariate logistic regression models were used to examine determinants of suicide risk. RESULTS Across all models, diagnosis of depression was the strongest predictor of suicide plan and/or attempt (OR = 5.54, 95% CI = 3.71-8.27, p < 0.001). Comparing clinical symptoms between suicidal and non-suicidal groups at the time of admission, the largest effect sizes were found for hopelessness (p < 0.001, η2 = 0.11), and guilt or shame (p < 0.001, η2 = 0.09). Female sex was identified as a significant factor for elevated suicidal risk (OR = 1.56, 95% CI = 1.01-2.21, p = 0.01), thus we stratified the regression model by sex to identify specific risk factors for suicide plan and/or attempt for males and females. Among males, having no confidant (OR = 2.13, 95% CI = 1.19-3.80, p = 0.01), presence of recent stressors (OR = 1.95, 95% CI = 1.16-3.29, p = 0.01), and participation in social activities (OR = 1.67, 95% CI = 1.02-2.71, p = 0.04) were important predictors, while among females, younger age (OR = 0.96, 95% CI = 0.94-0.97, p < 0.001) increased odds of suicide plan and/or attempt. CONCLUSION EMR-derived findings highlight different psychosocial and clinical determinants for males and females associated with suicide plan or attempt prior to psychiatric admission. Identifying precipitating factors that elevate imminent suicide risk may inform suicide prevention efforts for psychiatric inpatients.

The Role of Sex in Genetic Association Studies of Depression. JOURNAL OF PSYCHIATRY AND BRAIN SCIENCE 2022; 7:e220013.

Abstract
Depression is the most common mental illness in the U.S. affecting nearly 40 million adults age 18 years and older. Depression has both genetic and environmental influences. In addition, women are more likely to be affected by depression than men. However, the relationship between genes and depression is complex and may be influenced by sex. Understanding the genetic basis of sex-specific differences for depression has the potential to lead to new biological understanding of the etiology of depression in females compared to males and to promote the development of novel and more effective pharmacotherapies. This review examines the role of sex in genetic associations with depression for both genome-wide association and candidate gene studies. While the genetic association signals of depression differ by sex, the role of sex in the heritability of depression is complex and warrants further investigation.

Abstract
This study sought to examine if mental health issues, namely depression and anxiety symptoms, and loneliness were experienced differently according to various demographic groups during the COVID-19 pandemic (i.e., a societal stressor). An online survey, comprising demographic questions and questionnaires on depression, anxiety and loneliness symptoms, was distributed in Canada during the height of social distancing restrictions during the COVID-19 pandemic. Respondents (N=661) from lower income households experienced greater anxiety, depression and loneliness. Specifically, loneliness was greater in those with an annual income <$50,000/yr versus higher income brackets. Younger females (18-29yr) displayed greater anxiety, depressive symptoms and loneliness than their male counterparts; this difference did not exist among the other age groups (30-64yr, >65yr). Moreover, loneliness scores increased with increasing depression and anxiety symptom severity category. The relationship between loneliness and depression symptoms was moderated by gender, such that females experienced higher depressive symptoms when encountering greater loneliness. These data identify younger females, individuals with lower income, and those living alone as experiencing greater loneliness and mental health challenges during the height of the pandemic in Canada. We highlight the strong relationship between loneliness, depression and anxiety, and emphasize increased vulnerability among certain cohorts.

Abstract
The relationship between adverse experiences and the emergence of pathology has often focused on characteristics of the stressor or of the individual (stressor appraisals, coping strategies). These features are thought to influence multiple biological processes that favor the development of mental and physical illnesses. Less often has attention focused on the aftermath of traumatic experiences, and the importance of safety and reassurance that is necessary for longer-term well-being. In some cases (e.g., post-traumatic stress disorder) this may be reflected by a failure of fear extinction, whereas in other instances (e.g., historical trauma), the uncertainty about the future might foster continued anxiety. In essence, the question becomes one of how individuals attain feelings of safety when it is fully understood that the world is not necessarily a safe place, uncertainties abound, and feelings of agency are often illusory. We consider how individuals acquire resilience in the aftermath of traumatic and chronic stressors. In this respect, we review characteristics of stressors that may trigger particular biological and behavioral coping responses, as well as factors that undermine their efficacy. To this end, we explore stressor dynamics and social processes that foster resilience in response to specific traumatic, chronic, and uncontrollable stressor contexts (intimate partner abuse; refugee migration; collective historical trauma). We point to resilience factors that may comprise neurobiological changes, such as those related to various stressor-provoked hormones, neurotrophins, inflammatory immune, microbial, and epigenetic processes. These behavioral and biological stress responses may influence, and be influenced by, feelings of safety that come about through relationships with others, spiritual and place-based connections.

Abstract
OBJECTIVES The objectives of this study were to investigate the effect of genetic and social factors on depressive symptoms and depression over time and to test whether social factors moderate the relationship between depressive symptoms and its underlying genetics in later life. METHODS The study included 2,279 participants with a mean follow-up of 15 years from the Longitudinal Aging Study Amsterdam with genotyping data. The personal genetic loading for depression was estimated for each participant by calculating a polygenic risk scores (PRS-D), based on 23,032 single nucleotide polymorphisms associated with major depression in a large genome-wide association study. Partner status, network size, received and given emotional support were assessed via questionnaires and depressive symptoms were assessed using the CES-D Scale. A CES-D Scale of 16 and higher was considered as clinically relevant depression. RESULTS Higher PRS-D was associated with more depressive symptoms whereas having a partner and having a larger network size were independently associated with less depressive symptoms. After extra adjustment for education, cognitive function and functional limitations, giving more emotional support was also associated with less depressive symptoms. No evidence for gene-environment interaction between PRS-D and social factors was found. Similar results were found for clinically relevant depression. CONCLUSION Genetic and social factors are independently associated with depressive symptoms over time in older adults. Strategies that boost social functioning should be encouraged in the general population of older adults regardless of the genetic liability for depression.
