Abstract Background Medical students are prone to mental disorders, such as depression and anxiety, and their psychological burden is mainly related to their highly demanding studies. Interventions are needed to improve medical students’ mental health literacy (MHL) and wellbeing. This study assessed the digital Transitions, a MHL program for medical students that covered blended life skills and mindfulness activities. Methodology This was a one group, quasi-experimental pretest-posttest study. The study population was 374 first-year students who started attending the medical faculty at the University of Turku, Finland, in 2018-2019. Transitions was provided as an elective course and 220 students chose to attend and 182 agreed to participate in our research. Transitions included two 60-minute lectures, four weeks apart, with online self-learning material in between. The content focused on life and academic skills, stress management, positive mental health, mental health problems and disorders. It included mindfulness audiotapes. Mental health knowledge, stigma and help-seeking questionnaires were used to measure MHL. The Perceived Stress Scale and General Health Questionnaire measured the students’ stress and health, respectively. A single group design, with repeated measurements of analysis of variance, was used to analyze the differences in the mean outcome scores for the 158 students who completed all three stages: the pre-test (before the first lecture), the post-test (after the second lecture) and the two-month follow-up evaluation. Results The students’ mean scores for mental health knowledge improved (-1.6, 95% Cl -1.9 to -1.3, P

Increasing evidence has shown that childhood anxiety can be effectively treated by Internet-based cognitive behavioral therapy (ICBT). Being able to predict why participants decide to drop out of such programs enables scarce resources to be used appropriately. The aim of this study was to report dropout predictors for a population-based ICBT intervention aimed at children with anxiety, together with the time they and their parents spent on the program and client satisfaction rates. The study focused on 234 Finnish children aged 10-13 who received an ICBT intervention, with telephone support, for anxiety symptoms, as a part of a randomized control trial. Their parents also had access to Internet-based material and participated in the weekly telephone calls with the coach. Possible drop out factors were explored and these included various family demographics, child and parent psychopathology and therapeutic alliance. Just under a fourth (23.9%) of the children dropped out of the intervention. The risk was higher if the child did not fulfill the criteria for any anxiety diagnosis or reported a poorer therapeutic alliance. Family demographics and the COVID-19 pandemic did not increase the risk. The families spent an average of 127 min on the webpage each week and an average of 32 min on the phone calls. The overall satisfaction with the program was 87% for the children and 95% for the parents. Both the children and the parents found the telephone calls helpful. These findings are important in clinical practice when assessing a family's eligibility for ICBT., (© 2024. The Author(s).)

The siblings of children with mental disorders are more likely to experience mental health issues themselves, but there has been a lack of sibling studies on selective mutism (SM). The aim of this population-based study was to use national registers to examine associations between children with SM and diagnoses of various mental disorder in their siblings. All singleton children born in Finland from 1987 to 2009, and diagnosed with SM from 1998 to 2012, were identified from national health registers and matched with four controls by age and sex. Their biological siblings and parents were identified using national registries and the diagnostic information on the siblings of the subjects and controls was obtained. The final analyses comprised 658 children with SM and their 1661 siblings and 2092 controls with 4120 siblings. The analyses were conducted using generalized estimating equations. Mental disorders were more common among the siblings of the children with SM than among the siblings of the controls. The strongest associations were observed for childhood emotional disorders and autism spectrum disorders after the data were adjusted for covariates and comorbid diagnoses among SM subjects. The final model showed associations between SM and a wide range of disorders in siblings, with strongest associations with disorders that usually have their onset during childhood. Our finding showed that SM clustered with other mental disorders in siblings and this requires further research, especially the association between SM and autism spectrum disorders. Strong associations with childhood onset disorders may indicate shared etiologies., (© 2022. The Author(s).)

Aim: We examined the associations between preterm birth, poor foetal growth and anxiety disorders among children and adolescents. Additionally, we examined the impact of common comorbidities and specific anxiety disorders separately., Methods: Three Finnish registers provided data on a nationwide birth cohort of 22,181 cases with anxiety disorders and 74,726 controls. Conditional logistic regression was used to examine the associations., Results: Extremely very preterm birth and moderate-late preterm birth were associated with increased adjusted odds ratios (aOR) for anxiety disorders (aOR 1.39, 95% CI 1.11-1.75 and aOR 1.13, 95% CI 1.03-1.23, respectively). Weight for gestational age of less than -2SD (aOR 1.29, 95% CI 1.17-1.42) and -2SD to -1SD (aOR 1.08, 95% CI 1.03-1.14) were associated with increased odds ratios for anxiety disorders. When comorbidities were considered, the associations became statistically insignificant for pure anxiety disorders, but remained significant in the groups with comorbid depressive or neurodevelopmental disorders., Conclusion: Preterm birth and poor foetal growth increased the odds for anxiety disorders. However, the associations seem to be explained by the conditions of comorbid depressive and neurodevelopmental disorders. Comorbidities should be considered when examining and treating child and adolescent anxiety disorders., (© 2022 The Authors.

Objective: Mode of delivery and well-being markers for newborn infants have been associated with later psychiatric problems in children and adolescents. However, only few studies have examined the association between birth outcomes and anxiety disorders and the results have been contradictory., Methods: This study was a Finnish population-based register study, which comprised 22,181 children and adolescents with anxiety disorders and 74,726 controls. Three national registers were used to collect the data on exposures, confounders and outcomes. Mode of delivery, the 1-min Apgar score, umbilical artery pH and neonatal monitoring were studied as exposure variables for anxiety disorders and for specific anxiety disorders. Conditional logistic regression was used to examine these associations., Results: Unplanned and planned cesarean sections increased the odds for anxiety disorders in children and adolescents (adjusted OR 1.08, 95% CI 1.02-1.15 and aOR 1.12, 95% CI 1.05-1.19, respectively). After an additional adjustment for maternal diagnoses, unplanned cesarean sections remained statistically significant (aOR 1.11, 95% CI 1.04-1.18). For specific anxiety disorders, planned cesarean sections and the need for neonatal monitoring increased the odds for specific phobia (aOR 1.21, 95% CI 1.01-1.44 and aOR 1.28, 95% CI 1.07-1.52, respectively)., Conclusions: Birth by cesarean section increased the odds for later anxiety disorders in children and adolescents and unplanned cesarean sections showed an independent association. Further studies are needed to examine the mechanisms behind these associations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Ståhlberg, Upadhyaya, Polo-Kantola, Khanal, Luntamo, Hinkka-Yli-Salomäki and Sourander.)

Purpose: Pain symptoms are common in childhood. They often lead to functional impairment and co-occur with psychiatric difficulties. Although children's lives have undergone enormous changes in recent decades, long-term data on changes in pain symptoms, and in comorbid psychiatric difficulties, is lacking. This knowledge is crucial, as co-occurring psychiatric symptoms are significant predictors of long-term outcome for children who suffer from pain. The main purpose of the present study was to explore secular changes in comorbid pain and psychiatric symptoms., Methods: Four population-based, cross-sectional surveys of 8-9-year-old children were conducted in Southwest Finland in 1989, 1999, 2005, and 2013. Identical methodologies and questionnaire-based measures were used each study year. Participation ranged from 891 to 986 over the study period. The children were asked about the frequency of headache, abdominal pain, and other pains. Children, their parents, and teachers provided information on the child's psychiatric difficulties, including internalizing and externalizing symptoms., Results: The cumulative odds ratios and 95% confidence intervals for the overall prevalence of pain symptoms increased among both genders from 1989 to 2013 and ranged from 1.4 (1.03-1.8) for other pains to 2.4 (1.7-3.3) for abdominal pain. Comorbid internalizing symptoms increased among girls with odd ratios and 95% CIs of 1.8 (1.03-3.1) for children with any kind of pain, and 3.0 (1.4-6.2) for children with headache. No changes were found among boys., Conclusion: Overall pain symptoms doubled in both genders, but the most novel finding was that comorbid emotional difficulties tripled among girls who reported headaches. Further research is needed to confirm, and explain, these findings., (© 2022. The Author(s).)

Background: The COVID-19 pandemic has had a major impact on families' daily routines and psychosocial well-being, and technology has played a key role in providing socially distanced health care services., Objective: The first objective of this paper was to describe the content and delivery of a single-session, internet-based cognitive behavioral therapy (iCBT) intervention, which has been developed to help parents cope with children's anxiety and manage daily situations with their children. The second objective was to report user adherence and satisfaction among the first participants who completed the intervention., Methods: The Let's Cope Together intervention has been developed by our research group. It combines evidence-based CBT elements, such as psychoeducation and skills to manage anxiety, with parent training programs that strengthen how parents interact with their child and handle daily situations. A pre-post design was used to examine user satisfaction and the skills the parents learned. Participants were recruited using advertisements, media activity, day care centers, and schools and asked about background characteristics, emotional symptoms, and parenting practices before they underwent the iCBT. After they completed the 7 themes, they were asked what new parenting skills they had learned from the iCBT and how satisfied they were with the program., Results: Of the 602 participants who filled in the baseline survey, 196 (32.6%) completed the program's 7 themes, and 189 (31.4%) completed the postintervention survey. Most (138/189, 73.0%) of the participants who completed the postintervention survey were satisfied with the program and had learned skills that eased both their anxiety (141/189, 74.6%) and their children's anxiety (157/189, 83.1%). The majority (157/189, 83.1%) reported that they learned how to organize their daily routines better, and just over one-half (100/189, 53.0%) reported that the program improved how they planned each day with their children., Conclusions: The single-session iCBT helped parents to face the psychological demands of the COVID-19 pandemic. Future studies should determine how the participation rate and adherence can be optimized in digital, universal interventions. This will help to determine what kinds of programs should be developed, including their content and delivery., (©Tarja Korpilahti-Leino, Terhi Luntamo, Terja Ristkari, Susanna Hinkka-Yli-Salomäki, Laura Pulkki-Råback, Otto Waris, Hanna-Maria Matinolli, Atte Sinokki, Yuko Mori, Mami Fukaya, Yuko Yamada, Andre Sourander.

Background: There has been a lack of research about the time trends and socio-demographic risk factors for children and adolescents who receive treatment for anxiety disorders. This study aimed to fill these gaps in our knowledge by examining a nationwide sample of Finnish children and adolescents diagnosed in specialized healthcare settings., Methods: This study comprised national register data of all singleton children born in Finland from 1992-2006 who were diagnosed with anxiety disorders from 1998-2012. The changes in time trends in incidence were studied by dividing the study sample into three cohorts by birth years: 1992-1996, 1997-2001 and 2002-2006, who were followed up until the age of 20, 15 and 10 years, respectively. The 22,388 individuals with anxiety disorders were age and gender matched with 76,139 controls from the general population. Logistic regression was used to examine the socio-demographic risk factors and anxiety disorders in the entire sample. Comorbid disorders were examined in the oldest birth cohort (1992-1996 born)., Results: Comparing the 1992-1996 and 2002-2006 cohorts showed that the cumulative incidence of treated anxiety disorders at the age of 10 increased from 0.3 to 1.2% among females and 0.46 to 1.9% among males. Subjects had higher likelihood for being diagnosed with an anxiety disorder if their mothers had low maternal socio-economic status class at birth (OR 1.53, 95% CI 1.45-1.61) compared to higher SES class, and marital status was single at the time of birth (OR 2.02, 95% CI 1.87-2.17) compared to married or in a relationship. They had lower risk of anxiety disorders diagnosis if born in rural (OR 0.82, 95% CI 0.79-0.86) or semi-urban areas (OR 0.79, 95% CI 0.76-0.82) when compared to urban residence. There was a wide range of psychiatric comorbidities, and unipolar depression was the most common (31.2%)., Conclusion: Anxiety disorders diagnosed by specialized Finnish services increased from 1998-2012 in both genders. This could indicate a real increase in overall anxiety disorders or an increase in treatment seeking. The findings on maternal socioeconomic status and single parenting improve the recognition of the environmental risk factors for anxiety disorders among children and adolescents., (© 2022.

The changes were maintained at the two-month follow up (-1.7, 95% Cl -2.0 to -1.4, P<.001 and 1.0, 95% Cl 0.2 to 1.8, P=.019, respectively). The students' stress levels reduced (P=.022) and their attitudes towards help-seeking improved after the program (P<.001), but these changes were not maintained at the two-month follow up. The stigma of mental illness did not change during the study (P=.13)., Conclusions: The digital Transitions program was easily integrated into the university curriculum and it improved the students' mental health literacy and wellbeing. The program may respond to the increasing global need for universal digital services, especially during the lockdowns due to the COVID-19 pandemic., Trial Registration: The trial was registered at the ISRCTN registry (26 May 2021), registration number 10.1186/ ISRCTN10565335 )., (© 2021.

Objective: There have been inconsistent findings on the associations among prematurity, poor fetal growth, and depression. We examined the associations among gestational age, poor fetal growth, and depression in individuals aged 5 to 25 years., Method: We identified 37,682 case subjects based on International Classification of Diseases, Ninth Revision code 2961 and International Classification of Diseases, Tenth Revision codes F32.0-F32.9 and F33.0-F33.9 from the Care Register for Health Care, and 148,795 matched controls from the Finnish Central Population Register. Conditional logistic regression examined the associations between gestational age by each gestational week, poor fetal growth, and depression. The associations were adjusted for parental age and psychopathology, paternal immigrant status, maternal substance abuse, depression, number of previous births, marital status, socio-economic status, smoking during pregnancy, and the infant's birthplace., Results: In the adjusted models, increased risk of depression was found in children born ≤25 weeks (adjusted odds ratio [aOR] 1.89, 95% CI 1.08-3.31), at 26 weeks (aOR 2.62, 95% CI 1.49-4.61), at 27 weeks (aOR 1.93, 95% CI 1.05-3.53), and ≥42 weeks (aOR 1.11, 95% CI 1.05-1.19). In girls, extremely preterm birth was associated with depression diagnosed at 5 to 12 years (aOR 2.70, 95% CI 1.83-3.98) and 13 to 18 years (aOR 2.97, 95% CI 1.84-4.78). In boys, postterm birth (≥42 weeks) was associated with depression diagnosed at 19 to 25 years (aOR 1.28, 95% CI 1.07-1.54). Poor fetal growth was associated with an increased risk of depression in full-term infants (aOR 1.06, 95% CI 1.03-1.10) and postterm infants (aOR 1.24, 95% CI 1.08-1.43)., Conclusion: Preterm birth before 28 weeks of gestation appeared to play a role in the development of childhood depression. Smaller effects were also seen in postterm births, especially in boys., (Copyright © 2021. Published by Elsevier Inc.)

Introduction: Childhood anxiety is common, causes significant functional impairment and may lead to psychosocial problems by adulthood. Although cognitive behavioural therapy (CBT) is effective for treating anxiety, its availability is limited by the lack of trained CBT therapists and easily accessible local services. To address the challenges in both recognition and treatment, this study combines systematic anxiety screening in the general population with a randomised controlled trial (RCT) on internet-assisted CBT (ICBT) with telephone coaching. Child, family and intervention-related factors are studied as possible predictors or moderators, together with the COVID-19 pandemic., Methods and Analysis: The study is an open two-parallel group RCT, stratified by sex, that compares ICBT with telephone coaching to an education control. Children aged 10-13 are screened at yearly school healthcare check-ups using five items from the Screen for Child Anxiety Related Disorders (SCARED) Questionnaire. The families of children who screen positive for anxiety are contacted to assess the family's eligibility for the RCT. The inclusion criteria include scoring at least 22 points in the 41-item SCARED Questionnaire. The primary outcome is the SCARED child and parent reports. The secondary outcomes include the impact of anxiety, quality of life, comorbidity, peer relationships, perceptions of school, parental well-being and service use. Additional measures include demographics and life events, anxiety disorder diagnoses, as well as therapeutic partnerships, the use of the programme and general satisfaction among the intervention group., Ethics and Dissemination: The study has been approved by the research ethics board of the Hospital District of South West Finland and local authorities. Participation is voluntary and based on informed consent. The anonymity of the participants will be protected and the results will be published in a scientific journal and disseminated to healthcare professionals and the general public., Trial Registration Number: ClinicalTrials.gov NCT03310489, pre-results, initially released on 30 September 2017., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: The global prevalence of depression has increased in recent decades and so has the average age of parenthood. Younger and older parental age have been associated with several mental disorders in their offspring, but the associations for depression have been inconsistent., Methods: This study comprised 37,682 singleton births in Finland from 1987- 2007. The subjects were living in Finland at the end of 2012 and had a depressive disorder recorded in the Care Register for Health Care. We also randomly identified 148,795 controls from the Population Register. When missing obsevations excluded the sample was N cases =18,708 and N controls =77,243. The results were adjusted for the parents' psychiatric history, depression history, marital status and place of birth, the mothers' maternal socioeconomic status, smoking during pregnancy and previous births and the children's birth weight., Results: We found a U-shaped association between offspring depression and the age of both parents. The highest odds of depression occurred when the fathers were aged 50 plus years (adjusted Odds Ratio (ORa) 1.51, 95% CI 1.23-1.86) and the mothers were under 20 (ORa 1.44, 95% CI 1.29-1.60) compared to the reference category of parents aged 25-29 years., Limitations: The study was limited to depression diagnosed by specialised health care services and had a relatively short follow-up period. Some data were missing and that could lead to risk estimation biases., Conclusion: Diagnosed depression was higher among the offspring of younger and older parents. The results suggest that the age of the parent is etiologically associated with offspring depression., (Copyright © 2021 The Authors. Published by Elsevier B.V. All rights reserved.)

Anxiety disorders are the most common mental disorders in children and youth. Effective screening methods are needed to identify children in need of treatment. The Screen for Child Anxiety Related Emotional Disorders (SCARED) questionnaire is a widely used tool to assess childhood anxiety. We aim toevaluate the psychometric properties of the SCARED questionnaire, test the SCARED factor structure, and evaluate the prevalence of anxiety symptoms in a community sample of Finnish elementary school children, based on both a child and parent report. The sample included all pupils (n = 1,165) in grades 2 through 6 (ages 8-13) in four elementary schools in the city of Turku, Finland. Children completed a Finnish translation of the SCARED questionnaire at school, with one parent report questionnaire per child completed at home. In total, 663 child-parent dyads (56.9%) completed the questionnaire. Internal consistency was high for both child and parent reports on all subscales (0.71-0.92), except for school avoidance (0.57 child, 0.63 parent report). Inter-rater reliability ranged from poor to fair across subscales (intraclass correlation 0.27-0.47). Self-reported anxiety scores were higher than the parent reported scores. Females had significantly higher total scores than males based on the child reports (p = 0.003), but not the parent reports. In the confirmatory factor analysis, hypothesized models did not have a good fit with the data, and modification was needed. The Finnish SCARED questionnaire has good internal consistency. Low child-parent agreement calls for the importance of including both child and parental reports in the assessment of anxiety symptoms., (© 2020 Scandinavian Psychological Associations and John Wiley & Sons Ltd.)

Background: Prenatal and perinatal risk factors for anxiety disorders have rarely been studied, even though they are highly prevalent in children and adolescents. It is important to identify the common risk factors, so that targeted preventive care and early interventions can be provided., Methods: A systematic review of the PubMed and PsycInfo databases was conducted to 25 October 2019, according to the Preferred Reporting Items of Systematic Reviews and Meta-analyses guidelines. The protocol was registered on the Prospective Register of Systematic Reviews and the quality assessment was carried out using the Joanna Briggs tools., Results: The review identified 31 studies from eight countries, including three register studies. Cohort sizes ranged from 69 to 89,404 and diagnoses cases ranged from 4 to 7867. Although various risk factors had been researched, only few of them had been repeatedly studied and the findings were highly inconsistent. The associations between the different risk factors and anxiety disorders seemed weak compared to many other psychiatric disorders, but preterm birth and maternal somatic illnesses may increase the risk for anxiety disorders in offspring., Limitations: The studies varied considerably by study design, risk factors and anxiety disorders studied, sample sizes and follow up periods., Conclusions: Prenatal and perinatal risk factors for anxiety disorders have been under-researched, compared to other psychiatric disorders. Our systematic review found weak links to prenatal events, but flagged up preterm birth and maternal somatic illnesses as possible avenues for future research., (Copyright © 2020 Elsevier B.V.

Aim: To examine the association between several perinatal and obstetric risk factors and reactive attachment disorder in children diagnosed in specialised services., Methods: In this nested case-control study, 614 cases with reactive attachment disorder and 2423 controls matched with age and sex were identified from Finnish national registers. Conditional logistic regression was used to examine the association between a number of perinatal risk factors and reactive attachment disorder., Results: In the adjusted analysis, a low birthweight of <2500 g was associated with an increased odds of reactive attachment disorder, with an odds ratio (OR) of 1.96 and 95% confidence interval (CI) of 1.17, 3.30 and a birthweight of 4000-4499 grams was associated with decreased odds OR 0.49 (95% CI 0.31, 0.75). The odds for being diagnosed with reactive attachment disorder increased with a gestational age of <32 weeks OR 3.72 (95% CI 1.52, 9.10), induced labour OR 1.34 (95% CI 1.03, 1.75) and monitoring in a neonatal intensive care unit (NICU) OR 1.67 (95% CI 1.09, 2.55)., Conclusion: We found associations between low birthweight, preterm birth, NICU admission and reactive attachment disorder. The findings add to the current literature on the understanding of the development of reactive attachment disorder in children., (© 2020 Foundation Acta Paediatrica.

Background: Postpartum depression (PPD) negatively impacts maternal health, parenting and development of children. Most previous studies on PPD risk factors are based on Western populations. Additionally, little is known about the association between psychosocial factors during early pregnancy period and PPD. We aimed to identify early risk factors for PPD until three months after delivery using a longitudinal population-based sample from Japan., Methods: The data was collected from 1050 mothers at four time points: first trimester, after the birth, and one and three months post-delivery. Mothers who had a Japanese Edinburgh Postnatal Depression Scale (EPDS) cutoff score above 9 at one or 3 months after delivery were recognized as having PPD (n = 91/8.7%)., Results: Negative feelings about pregnancy, combined breast and bottle feeding, first-time motherhood, motherhood 24 or less years old, perceived maternal mental illness before pregnancy, and lack of social support were all significantly associated with PPD at three months after delivery., Limitations: The data was collected from one city in Japan, which limits the generalization of the findings. Additionally, PPD was assessed by an EPDS questionnaire, and not by a clinical interview., Conclusions: Even after controlling for the perceived mental illness before pregnancy, several risk factors as early as in the first trimester were associated with PPD. These risk factors should be identified and the mothers should be offered a suitable intervention, in order to prevent the development of PPD., Competing Interests: Declaration of Competing Interest On behalf of all authors, the corresponding author states that there is no conflict of interest., (Copyright © 2020 Elsevier B.V.

Background: Selective mutism (SM) is nowadays considered a relatively rare anxiety disorder characterized by children failing to speak in certain situations. Research on risk factors for SM are limited in comparison to other psychiatric disorders. The aim of this study was to examine several potential risk factors for SM in a large nationwide cohort, namely parental psychopathology, parental age, maternal SES, urbanicity, maternal marital status and parental immigration status., Methods: This nested case-control study comprised 860 cases with SM, identified from the Finnish Hospital Discharge Register and 3250 controls matched for sex and age from the Finnish Central Population Register. Conditional logistic regression was used to examine the association between the risk factors and SM., Results: If both parents had any psychiatric disorder, this almost tripled their odds of having a child with SM (OR 2.8, 95% CI 2.0-4.0). There were increased rates of all types of psychiatric disorders in the parents of the children with SM, with a wider range of diagnoses among the mothers than fathers. Fathers over 35 years (OR 1.4, 95% CI 1.1-1.8) were significantly more likely to have children with SM. Offspring of a single mother had a 2-fold (OR = 2.0, 95% CI 1.4-3.0) increased odds of SM than mothers who were married or in a relationship., Conclusions: Several parental psychiatric disorders were associated with offspring SM. This points towards a shared aetiology of psychiatric disorders. Findings on paternal age and single motherhood help to improve our understanding of risk factors for SM.

Objective: We assessed changes in traditional and cyberbullying victimization, and their associations with mental health, before and after the introduction of a nationwide antibullying program in Finnish schools in 2009., Method: This time-trend assessment comprised two methodologically identical cross-sectional survey studies, with 2,061 adolescents in 2008 (response rate 90.2%) and 1,936 in 2014 (91.8%). Their mean age was 14.4 years. They completed questionnaires about traditional and cyberbullying, mental health, and perceptions of school safety. Odds ratios (OR) and 95% CIs are presented with 2008 as the reference year., Results: From 2008 to 2014, traditional victimization decreased from 28.9% to 19.1% (odds ratio [OR] = 0.5, 95% CI = 0.4-0.7) among boys and from 23.2% to 17.4% (OR = 0.7, 95% CI = 0.6-0.9) among girls. Cyberbullying victimization remained fairly stable at 3.3% and 3.0% (OR = 0.7, 95% CI = 0.4-1.2) for boys and at 2.7% and 4.1% (OR = 1.4, 95% CI = 0.9-2.4) for girls. Combined traditional and cyberbullying victimization decreased from 6.1% to 3.9% (OR = 0.5, 95% CI = 0.4-0.8) among boys and from 7.5% to 6.7% (OR = 0.8, 95% CI = 0.6-1.2) among girls. Those experiencing both traditional and cyberbullying reported the highest mental health problems. Perceived school safety improved among boys, but not among girls. Both boys and girls reported greater efforts by teachers and fellow students to stop bullying., Conclusion: Combined traditional and cyberbullying victimization was an indicator of comorbid mental health problems. Interventions that target both types of bullying, and that are integrated with mental health promotion, are needed., (Copyright © 2019 American Academy of Child and Adolescent Psychiatry.

Background: Knowledge of time trends for depression is important for disease prevention and healthcare planning. Only a few studies have addressed these questions regarding the incidence and cumulative incidence of diagnosed depression from childhood to early adulthood and findings have been inconclusive. Aim: The aim of this national register-based Finnish study was to report the time trends of the age-specific and gender-specific incidence and cumulative incidence of diagnosed depression. Methods: The study sample included all 1,245,502 singletons born in Finland between 1 January 1987 and 31 December 2007 and still living in Finland at the end of 2012. The participants were divided into three cohorts by birth year: 1987-1993, 1994-2000 and 2001-2007. Depression diagnoses (ICD-9: 2961; ICD-10: F32, F33) given in 1995-2012 were available and identified from the Care Register for Health Care. Results: Ten percent of the females and five percent of the males were diagnosed with depression in specialized services by age 25 years. The cumulative incidence of depression by age 15 years rose from 1.8% (95% CI 1.8-1.9) to 2.9% (95% CI 2.8-3.0) in females and from 1.0% (95% CI 1.1-1.2) to 1.6% (95% CI 1.6-1.7) in males when the cohorts born 1987-1993 and 1994-2000 were compared. Conclusions: A larger proportion of young people in Finland are diagnosed with depression in specialized services than before. This can be due to better identification, more positive attitudes to mental health problems and increased availability of the services.

This nationwide population-based register study examined the family and parental risk factors associated with offspring reactive attachment disorder (RAD). We identified 614 children diagnosed with RAD from the Finnish Care Register for Health Care and each case was matched with four controls. Univariate and multivariate models examined the associations between risk factors and RAD. In the multivariate model, offspring RAD was associated with only mother, only father and both parents having psychiatric diagnoses. Increased odds were observed for maternal smoking during pregnancy, single motherhood and paternal age ≥ 45 years. This study provides information on several parental adversities and offspring RAD that have important implications for public health, when planning early prevention and interventions in infant mental health.

The use of children's mental health services has increased, but most children with psychiatric problems are still not in contact with these services. This time-trend study assessed changes in considered and reported service use over a 24-year period and studied the factors associated with it using four cross-sectional studies. Information was gathered on 8-year-old children living in the area covered by Turku University Hospital, Finland, at four time points: 986 children in 1989, 891 in 1999, 930 in 2005, and 942 in 2013. The same study design, methods and school districts were used each year and the participation rates varied between 86 and 95%. Parents and teachers completed questionnaires concerning the child's psychiatric symptoms and service use. The considered and reported service use increased continuously during the study period. In 1989, 2.4% of children had used services and in 2013 this was 11.0% (OR 5.0, 95% CI 3.1-8.0). Reported service use also increased among children with comorbid problems, from 18.3 to 50.7% (OR 5.0, 95% CI 2.1-12.0). Psychiatric problems and some family factors were associated with service use, but the increase was not explained by these factors. The increase in child mental health service use may reflect better public awareness of mental health problems, fewer barriers to accessing care and decrease of stigma. Although more children are using mental health services, there are still a large number of children with mental health problems who have not been in contact with services.

Background: Impaired maternal bonding has been associated with antenatal and postnatal factors, especially postpartum depression. Only a few population-based, longitudinal studies have examined the association between maternal depression and bonding in outside western countries. In addition, little is known about the association between psychosocial factors during pregnancy and impaired maternal bonding. The aim of this study was to investigate risk factors associated with impaired maternal bonding 3 months after delivery using Japanese population-based, longitudinal study from pregnancy period to 3 months after delivery., Methods: This study was performed at the public health care center in Hekinan city, Aichi prefecture, Japan. Mothers who participated the infant's health check-up 3 months after delivery from July 2013 to Jun 2015 completed the Postpartum Bonding Questionnaire (PBQ) and the Edinburgh Postnatal Depression Scale (EPDS) 1 month after delivery. Information was also provided from home visit at 1 month after delivery, birth registration form, and pregnancy notification form. The study included 1060 mothers with a mean age of 29.90 years, who had given birth at a mean of 38.95 weeks., Results: Bivariate and multivariate logistic regression analyses were conducted to identify the association between antenatal and postnatal factors and impaired maternal bonding. The main findings were that maternal negative feelings about pregnancy (OR = 2.16, 95% CI = 1.02-4.56) and postpartum depression at 1 month after delivery (OR = 7.85, 95% CI = 3.44-17.90) were associated with higher levels of impaired maternal bonding 1 months after delivery. Mothers who had delivered their first child had increased odds of a moderate level of impaired maternal bonding 3 months after delivery (OR = 1.85, 95% CI = 1.22-2.81)., Conclusions: The findings emphasize the importance of identifying mothers with depression and those with maternal negative feelings towards pregnancy to assess possible impaired maternal bonding.

This study investigated associations between pain symptoms in mid-childhood and severe suicidality in adolescence and early adulthood. Severe suicidality was defined as completed suicide or suicidal attempt requiring hospital admission. In a nationwide prospective population-based study (n = 6,017), parents and children were asked about the child's headache and abdominal pain at age eight. The outcome was register-based data on suicide or suicidal attempt requiring hospital treatment by age 24. Family composition, parental educational level, and the child's psychiatric symptoms reported by the child, parents and teacher at baseline were included as covariates in statistical analyses. Boys' abdominal pain reported by the parents was associated with later severe suicidality after adjusting for family composition, parental educational level, and childhood psychiatric symptoms at baseline. In addition, the association between boys' own report of headache and later severe suicidality reached borderline significance in unadjusted analysis. Girls' pain symptoms did not predict later severe suicidality.

The aims of this study were to examine the prevalence, co-occurrence, and psychosocial determinants of self-perceived headache, abdominal pain, and sleep problems among adolescents. The adolescents from two cities in Finland (n = 2,215, 90.9% of the target population) attending 7th and 9th grade (age range 13-18 years) participated in the cross-sectional survey inquiring about frequency of headache, abdominal pain, sleep problems, and psychosocial difficulties. The 6-month prevalence of weekly headache was 13%, abdominal pain 6%, and sleep problems 27%. All three symptoms were strongly associated with each other. Of the adolescents suffering from one symptom, 32% reported one co-occurring symptom and 17% two co-occurring symptoms. In the multivariate analysis, female gender, experience of psychological difficulties, emotional symptoms, smoking, victimization, and feeling not cared about by teachers were independently associated with all the individual symptoms, as well as an increasing number of symptoms. Sleep problems were associated with older age and peer and alcohol problems. Abdominal pain was associated with conduct problems, and both headache and abdominal pain were linked with immigration background. An increasing number of symptoms was associated with older age, having a chronic illness, and conduct and alcohol problems. Adolescents' headache, abdominal pain and sleep problems were common and often co-occurred. An increasing frequency of each symptom and number of symptoms were associated with psychosocial factors in a similar way. Screening for psychiatric symptoms, substance use, victimization and difficulties with teachers should be included in the assessment of adolescents who suffer from recurrent headache, abdominal pain or sleep problems.

Background: The existing knowledge about long-term psychosocial consequences of childhood pain is scarce. The current study investigated childhood pain symptoms as potential risk factors for antidepressant use in adolescence and early adulthood., Methods: A representative sample of eight-year-old children (n=6017) and their parents were asked about the prevalence of the child's headache, abdominal pain, and unspecified pain symptoms. The associations with antidepressant purchases by age 24, based on the nationwide prescription register, were analyzed separately for each symptom and each reporter. Sex, parental educational level, and child-, parent- and teacher-reported child's psychiatric symptoms at baseline were included as confounding variables., Results: In the sex-adjusted model, the child's own report of headache and other pains, and the parents' report of their child's abdominal pain, predicted antidepressant purchases. When confounding variables were included in the final model, only the child's own report of headache predicted antidepressant use with a dose-response relationship. The hazard ratios and 95% confidence intervals for frequent and for almost daily headache were 1.6 (1.3-2.0) and 2.1 (1.5-2.9), respectively, in the sex-adjusted model, and 1.5 (1.2-1.8) and 1.7 (1.2-2.5) in the final model., Limitations: The assessment of each pain symptom was based on one question for each reporter. The specific indications for the described medication could not be defined., Conclusions: Health care professionals should also ask children themselves about the pain symptoms. They should be aware that children with pain are at increased risk of suffering later from conditions that require antidepressant treatment., (Copyright © 2011 Elsevier B.V. All rights reserved.)

Context: To our knowledge, no population study examining psychosocial and psychiatric risk factors associated with cyberbullying among adolescents exists., Objective: To study cross-sectional associations between cyberbullying and psychiatric and psychosomatic problems among adolescents., Design: Population-based cross-sectional study., Setting: Finland., Participants: The sample consists of 2215 Finnish adolescents aged 13 to 16 years with complete information about cyberbullying and cybervictimization., Main Outcome Measures: Self-reports of cyberbullying and cybervictimization during the past 6 months., Results: In the total sample, 4.8% were cybervictims only, 7.4% were cyberbullies only, and 5.4% were cyberbully-victims. Cybervictim-only status was associated with living in a family with other than 2 biological parents, perceived difficulties, emotional and peer problems, headache, recurrent abdominal pain, sleeping difficulties, and not feeling safe at school. Cyberbully-only status was associated with perceived difficulties, hyperactivity, conduct problems, low prosocial behavior, frequent smoking and drunkenness, headache, and not feeling safe at school. Cyberbully-victim status was associated with all of these risk factors. Among cybervictims, being cyberbullied by a same-sex or opposite-sex adult, by an unknown person, and by a group of people were associated with fear for safety, indicating possible trauma., Conclusions: Both cyberbullying and cybervictimization are associated with psychiatric and psychosomatic problems. The most troubled are those who are both cyberbullies and cybervictims. This indicates the need for new strategies for cyberbullying prevention and intervention.
