The purpose of the current review was to examine recent cross-national trends in suicide mortality rates among 10- to 19-year-olds. This study extracted suicide mortality data from the World Health Organization's (WHO) Mortality Database for the most recent year (since 2010) from any country with available high-quality data (as defined by the WHO's guidelines). Data on access to lethal means (firearms, railways) and measures of economic quality (World Bank Income Group) and inequality (Gini coefficients) were obtained from publicly available data sources. Cross-national suicide mortality rates in youth were heterogeneous. The pooled estimate across all ages, sexes, and countries was 3.77/100,000 people. The highest suicide rates were found in Estonia, New Zealand, and Uzbekistan. Suicide rates were higher among older compared with younger adolescents and higher among males than females. The most common suicide methods were hanging/suffocation and jumping/lying in front of a moving object or jumping from a height. Firearm and railway access were related to suicide deaths by firearms and jumping/lying, respectively. Economic quality and inequality were not related to overall suicide mortality rates. However, economic inequality was correlated with a higher ratio of male:female suicides. This study provides a recent update of cross-national suicide trends in adolescents. Findings replicate prior patterns related to age, sex, geographic region, and common suicide methods. New to this review are findings relating suicide method accessibility to suicide mortality rates and the significant association between income inequality and the ratio of male:female suicide. Future research directions include expanding the worldwide coverage to more low- and middle-income countries, examining demographic groupings beyond binary sex and to race/ethnicity within countries, and clarifying factors that account for cross-national differences in suicide trends.

Associations among depression, perceived self-efficacy, and immune function and health in preadolescent children / Mary T. CASERTA in Development and Psychopathology, 23-4 (November 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-4 (November 2011) . - p.1139-1147 Titre : Associations among depression, perceived self-efficacy, and immune function and health in preadolescent children Type de document : texte imprimé Auteurs : Mary T. CASERTA, Auteur ; Peter A. WYMAN, Auteur ; Hongyue WANG, Auteur ; Jan A. MOYNIHAN, Auteur ; Thomas G. O'CONNOR, Auteur Année de publication : 2011 Article en page(s) : p.1139-1147 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Experimental animal studies and adult research consistently show that stress exposure and/or psychological symptoms are associated with poorer health and immune functioning. The application to children is not yet clear, however, and we lack developmental models for studies in this area. The objective of this paper was to test the hypothesis that self-reported self-efficacy and depression, two markers of psychological well-being in children, would predict immunity and rate of illnesses. The data are based on a prospective study of 141 healthy, normally developing children aged 7–13 years who were recruited from an ambulatory pediatric setting. Children completed self-efficacy and depression measures and had blood obtained for IL-6 plasma levels and natural killer cell functional assays on three occasions, 6 months apart. Parents maintained weekly child illness diaries over 1 year using a thermometer to record fever. Parent psychiatric symptoms and income were used as covariates. Results indicated that, across the three occasions of measurement collected over the 1-year period, higher perceived self-efficacy was significantly associated with lower plasma interleukin 6 concentrations. There was no overall main effect of depressive symptoms on immune measures; however, for older girls, higher depression was associated with elevated natural killer cell cytotoxicity and an increased rate of total illnesses and febrile illnesses. The findings provide some of the first evidence that psychological processes are associated with immunity and health in a normally developing sample of preadolescents. Furthermore, the pattern of results suggests a modified model of a link between psychological well-being and immunological processes in children. These results build on and expand research on the notion of allostatic load and develop a groundwork for developmental studies in this area.

Child maltreatment and youth suicide risk: A developmental conceptual model and implications for suicide prevention / Elizabeth D. HANDLEY ; Peter A. WYMAN ; Andrew J. ROSS ; Catherine CERULLI ; Assaf OSHRI in Development and Psychopathology, 35-4 (October 2023)

Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.

Depressive symptoms and immune response to meningococcal conjugate vaccine in early adolescence / Thomas G. O'CONNOR in Development and Psychopathology, 26-4 (Part 2) (November 2014)

However, available data are based almost entirely on animal and adult human studies; the application to children and adolescents is uncertain. We capitalized on the experimental leverage provided by a routine vaccination to examine the link between mood symptoms and the immune response to a vaccine challenge in early adolescence. One hundred twenty-six 11-year-olds for whom vaccine response data were available were assessed at prevaccination and 4 weeks, 3 months, and 6 months following vaccination; self-report ratings of depression and anxiety as well as measures of psychosocial and somatic risk were assessed prior to vaccine response. Analyses indicated that children's internalizing mood symptoms were associated with elevated and persistently higher antibody responses, with evidence extending to two of the four serogroups. The associations remained after controlling for multiple possible confounders (social class, body mass index, sleep, psychosocial risk, and pubertal status). The observed enhanced vaccine response associated with depressive and anxious symptoms in early adolescence may reflect an important developmental difference in immune system–brain interplay between adults and children, and it underscores the need for further developmental studies of psychoneuroimmunology.

Peer-adult network structure and suicide attempts in 38 high schools: implications for network-informed suicide prevention / Peter A. WYMAN in Journal of Child Psychology and Psychiatry, 60-10 (October 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-10 (October 2019) . - p.1065-1075 Titre : Peer-adult network structure and suicide attempts in 38 high schools: implications for network-informed suicide prevention Type de document : texte imprimé Auteurs : Peter A. WYMAN, Auteur ; Trevor A. PICKERING, Auteur ; Anthony R. PISANI, Auteur ; Kelly RULISON, Auteur ; Karen SCHMEELK-CONE, Auteur ; Calum HARTLEY, Auteur ; Madelyn GOULD, Auteur ; Eric D. CAINE, Auteur ; Mark LOMURRAY, Auteur ; Charles Hendricks BROWN, Auteur ; Thomas W. VALENTE, Auteur Article en page(s) : p.1065-1075 Langues : Anglais (eng) Mots-clés : Suicide prevention  network interventions  social integration  social networks Index. décimale : PER Périodiques Résumé : BACKGROUND: Strengthening social integration could prevent suicidal behavior. However, minimal research has examined social integration through relationship network structure. To address this important gap, we tested whether structural characteristics of school networks predict school rates of ideation and attempts. METHODS: In 38 US high schools, 10,291 students nominated close friends and trusted adults to construct social networks. We used mixed-effects logistic regression models to test individual student networks and likelihood of suicidal ideation (SI) and suicide attempts (SA); and linear regression models to estimate associations between school network characteristics and school rates of SI, SA, and SA among all with ideation. RESULTS: Lower peer network integration and cohesion increased likelihood of SI and SA across individual and school-level models. Two factors increased SA: student isolation from adults and suicidal students' popularity and clustering. A multivariable model identified higher SA in schools where youth-adult relationships were concentrated in fewer students (B = 4.95 [1.46, 8.44]) and suicidal students had higher relative popularity versus nonsuicidal peers (B = 0.93 [0.10, 1.77]). Schools had lower SA rates when more students named the same trusted adults named by friends and many students named the same trusted adults. When adjusting for depression, violence victimization and bullying, estimates for adult network characteristics were substantially unchanged whereas some peer effects decreased. CONCLUSIONS: Schoolwide peer and youth-adult relationship patterns influence SA rates beyond individual student connections. Network characteristics associated with suicide attempts map onto three theory-informed domains: social integration versus thwarted relational needs, group cohesion, and suicidal students' social influence. Network interventions addressing these processes, such as maximizing youth-adult connections schoolwide and heightening influence of youth with healthy coping, could create more protective schools. Longitudinal and intervention studies are needed to determine how schools differentiate in network structure and clarify reciprocal dynamics between network characteristics and suicidal behavior.
