Overweight in Adolescence and Young Adulthood in Association With Adult Cerebrovascular Disease: The NFBC1966 Study.

BACKGROUND: Risk factors for cerebrovascular disease in adulthood are well known. However, research on individuals' risk factors throughout their life span has been limited. This prospective cohort study aims to determine the effect of body mass index (BMI) and its changes in adolescence and young adulthood on early onset cerebrovascular disease. METHODS: This study includes 10 491 people (5185 women) from the Northern Finland Birth Cohort 1966. Height, weight, and BMI were measured at ages 14 and 31 years. Sex- and age-specific BMI ranges were used to define overweight and obesity. Data on ischemic and hemorrhagic cerebrovascular diseases between ages 14 and 54 years were extracted from national hospital and death registers. Cox proportion hazard models (95% CI) were used to estimate associations between BMI or its changes and cerebrovascular disease, while adjusting for sex, smoking, educational level, BMI at the other time point, and age at menarche for women. Additionally, sex-BMI interactions were calculated. RESULTS: A total of 452 individuals (4.7%) experienced cerebrovascular disease during the follow-up. The risk of ischemic cerebrovascular disease was increased for overweight women at ages 14 years (hazard ratio [HR], 2.49 [95% CI, 1.44-4.31]) and 31 years (HR, 2.13 [95% CI, 1.14-3.97]), as well as for obese women at ages 14 years (HR, 1.87 [95% CI, 0.76-4.58) and 31 years (HR, 2.67 [95% CI, 1.26-5.65]), with normal weight as the reference. These results were independent of earlier or later BMI. Similar associations were not found among men. The risk of hemorrhagic cerebrovascular disease was increased at age 31 years both among obese women (HR, 3.49 [95% CI, 1.13-10.7) and obese men (HR, 5.75 [95% CI, 1.43-23.1). The risk of any cerebrovascular disease related to overweight at age 14 years was 2.09× higher among girls than boys (95% CI, 1.06-4.15). The risk of ischemic cerebrovascular disease related to obesity at age 31 years was 6.96× higher among women than men (95% CI, 1.36-35.7). CONCLUSIONS: Among women, being overweight in adolescence or young adulthood increases the risk of cerebrovascular disease, especially ischemic, independent of their earlier or later BMI.

Childhood Developmental Milestones and Risk of Adult Cerebrovascular Disease: The Northern Finland Birth Cohort 1966.

INTRODUCTION: To the best of our knowledge, no previous studies have examined the relationship between childhood developmental milestones and risk of adulthood cerebrovascular disease (CeVD). We studied whether the risk of adult CeVD is associated with delayed attainment of motor and language milestones. METHODS: Within the Northern Finland Birth Cohort 1966, a total of 11,688 persons were followed from birth to either death, moving abroad or 54 years of age. CeVD diagnoses, i.e., ischemic and hemorrhagic strokes and transient ischemic attacks, were extracted from national registers with diagnostic coding based on recommendations of the World Health Organization. Cox proportional hazard models stratified by sex were used to estimate associations of motor development and language milestones between ages 0 and 4 years and adult CeVD women-to-men relative hazard ratios (RHRs) were estimated for each developmental milestone. Analyses were adjusted for family socioeconomic status and birth weight for gestational age. RESULTS: Altogether 498 (4.3%) CeVDs were recorded during follow-up. Among both sexes, later turning from back to tummy was associated with ischemic CeVD in adulthood with an adjusted hazard ratio (aHR) of 1.25 and 95% confidence interval (CI) 1.06-1.46 for men and an aHR: 1.20 (CI: 1.02-1.42) for women per 1 month delay in achievement. Delayed overall motor development, modeled by motor milestone principal component score, was related to increased risk of ischemic CeVD (aHR: 1.50; CI: 1.03-2.19) among men. Later achievement of making sounds was associated with any CeVD (aHR: 2.74; CI: 1.39-5.40) and especially ischemic CeVD (aHR: 3.41; CI: 1.65-7.06) among men with women-to-men RHR's of 0.17 (95% CI: 0.04-0.81) for any CeVD and RHR 0.18 (95% CI: 0.04-0.89) for ischemic stroke indicating risk to be lower in women compared to men. CONCLUSIONS: These findings suggest that later achievement of childhood milestones could be a predictor for development of CeVD risk. The results point toward a common neurodevelopmental background and could in part explain lifetime CeVD risk accumulation.

The effects of mindfulness-based interventions in medical students: a systematic review.

The number of studies on the effects of mindfulness on healthcare professionals is increasing. The main aim of this study was to collate the quantitative results of original studies analyzing the effects of mindfulness-based interventions on a variety of outcomes in medical students. We also analyzed how the study design and characteristics of the intervention affect the results, and identified qualitative effects of mindfulness interventions. A literature search was performed in different databases in June 2020. Original articles meeting the following criteria were included: (1) at least 50% of the participants were medical students, (2) included a mindfulness intervention, (3) analyzed any outcome relating to mindfulness intervention, (4) peer-reviewed (5) written in English. Eventually, 31 articles including 24 different samples were included. Over half of the studies were RCTs. In over half of the studies, the intervention was 4- to 10-week original Mindfulness-Based Stress Reduction or Mindfulness-Based Cognitive Therapy or a modification of these. In general, satisfaction with the interventions was good. Based on a meta-analysis, after the intervention, the intervention group had statistically significantly fewer symptoms of stress and distress and had higher mindfulness than the controls. The beneficial effects persisted in follow-ups over months or years. Both long and shorter courses and courses with and without face-to-face sessions were effective. Both controlled and uncontrolled studies had statistically significant results. Qualitative results revealed potential factors behind the quantitative effects. The number of studies on mindfulness interventions in medical students has increased drastically. Mindfulness-based interventions seem to offer a good possibility to enhance medical students' well-being.

Adolescent alcohol and cannabis use and early adulthood educational attainment in the 1986 Northern Finland birth cohort study.

BACKGROUND: Heavy alcohol and cannabis use during adolescence have been previously described as risk factors not only for morbidity in adulthood, but also social problems including adversities in educational attainment. Attempts to consider overlapping risk factors and confounders for these associations are needed. METHODS: Using weighted multivariable models, we examined prospective associations between age at first drink (AFD), age at first intoxication (AFI), frequency of alcohol intoxication, as well as self-reported alcohol tolerance (i.e., number of drinks needed for the subjective experience of intoxication), and lifetime cannabis use at age 15/16 years with subsequent educational attainment obtained from comprehensive registers until age 33 in the Northern Finland Birth Cohort 1986 (6,564 individuals, 49.1% male). Confounding variables including sex, family structure (intact vs. non-intact), maternal and paternal education level, behavioural/emotional problems in school at age 7/8 years, having a history of illicit substance use in adolescence, having any psychiatric diagnosis before age 16, and parental psychiatric diagnoses, were adjusted for. RESULTS: In this large birth cohort study with a 17-year follow-up, younger age at first intoxication, higher frequency of alcohol intoxication, and high self-reported alcohol tolerance at age 15/16 years were associated with poorer educational outcomes by the age of 33 years. These associations were evident regardless of potential confounders, including parental education and childhood behavioural/emotional problems. The association between adolescent cannabis use and educational attainment in adulthood was no longer statistically significant after adjusting for confounders including frequency of alcohol intoxication at age 15/16. CONCLUSIONS: Assessments of age of first alcohol intoxication, high self-reported alcohol tolerance and frequency of intoxication during adolescence should be included when implementing screening strategies aimed at identifying adolescents at risk for subsequent social problems.

Associations between neighbourhood characteristics, physical activity and depressive symptoms: the Northern Finland Birth Cohort 1966 Study.

BACKGROUND: Due to rapid urbanization, there is a need to better understand the relative roles of residential environment and physical activity in depression. We aimed to investigate whether neighbourhood characteristics are related to the presence of depressive symptoms and whether the association is modified by physical activity. METHODS: This cross-sectional study used the 46-year-old follow-up data (n = 5489) from the Northern Finland Birth Cohort 1966. Data on depressive symptoms, measured by Beck Depression Inventory-II, and self-reported and accelerometer-measured physical activity were included. Neighbourhood characteristics, population density, distance to the closest grocery store, bus stops and cycle/pedestrian paths, distance to the nearest parks and forests, residential greenness and level of urbanicity were calculated using Geographic Information System methods based on participants' home coordinates. RESULTS: According to ordinal logistic regression analyses adjusted for physical activity at different intensities and individual covariates, living in a neighbourhood with higher population density and urbanicity level were associated with a higher risk of experiencing more severe depressive symptoms. Higher residential greenness was associated with a lower risk of experiencing more severe depressive symptoms after adjustment for self-reported light and moderate-to-vigorous physical activity, accelerometer-measured moderate-to-vigorous physical activity and individual covariates. Both higher self-reported and accelerometer-measured physical activity were independently associated with a lower risk of more severe depressive symptoms. CONCLUSIONS: Both residential environment and physical activity behaviour play an important role in depressive symptoms; however, further research among populations of different ages is required. Our findings can be utilized when designing interventions for the prevention of depression.

Productivity costs of schizophrenia spectrum and other psychotic disorders by friction cost and human capital methods: The Northern Finland Birth Cohort 1966.

PURPOSE: Psychotic disorders are associated with substantial productivity costs; however no previous studies have compared these between schizophrenia spectrum (SSD) and other psychotic disorders (OP). The human capital method (HCM) and the friction cost method (FCM) are the two most common approaches to assess productivity costs. The HCM focuses on employees' perspectives on the costs, whereas the FCM demonstrates employers' perspectives. Studies comparing these methods when estimating the productivity costs of psychoses are lacking. METHODS: Utilizing the Northern Finland Birth Cohort 1966 with linkages to national registers, we compared the adjusted productivity costs of SSD (n = 216) and OP (n = 217). The productivity costs were estimated from ages 18 to 53 including projections to statutory retirement age using the FCM and HCM. RESULTS: When estimated via the HCM, productivity losses were higher for SSD (€193,940) than for OP (€163,080). However, when assessed using the FCM, costs were significantly lower for SSD (€2,720) than for OP (€4,430). Productivity costs varied by sex and various clinical and occupational factors. CONCLUSION: This study highlights how productivity costs vary by psychosis diagnosis. These differences should be noted when planning interventions. The low FCM estimates indicate the need of interventions before or during the early phases of psychoses. From a societal perspective, interventions are needed, particularly for those with highest HCM productivity losses, such as males with SSD. Besides psychiatric services, the roles of social services, employment agencies and occupational health care should be considered when helping individuals with psychoses to working life.

Prenatal maternal stress, breastfeeding and offspring ADHD symptoms.

There is increasing evidence to suggest that environmental factors are associated with ADHD, but results regarding prenatal maternal stress, unwanted pregnancy, breastfeeding, and ADHD in children are controversial and few prospective studies have been conducted. Using prospectively collected data from the Northern Finland Birth Cohort 1986 (n = 7,910) we studied potential risk factors for ADHD symptoms at 8 and 16 years of age, including prenatal maternal stress and unwanted pregnancy, and protective factors including the duration of breastfeeding. Prenatal stress was associated with an increased risk of ADHD symptoms at the age of 16 (OR = 1.95, 95% CI: 1.34-2.80) and an unwanted pregnancy correlated with hyperactivity symptoms in the offspring at the age of 8 (OR = 2.08, 95% CI: 1.55-2.77). We did not find an association between prenatal maternal stress and hyperactivity symptoms in the offspring at the age of 8 (OR = 0.87, 95% CI: 0.69-1.08) or with unwanted pregnancy and ADHD symptoms at the age of 16 (OR = 1.13, 95% CI: 0.57-2.02). In relation to breastfeeding, over three months of exclusive breastfeeding was associated with lower hyperactivity symptoms in the 8-year follow-up (OR = 0.65, 95% CI: 0.46-0.92) and there was evidence of same kind of relationship concerning non-exclusive breastfeeding, but the association was not statistically significant (OR = 0.76, 95% CI: 0.54-1.06). In 16-year follow-up, under six months of non-exclusive breastfeeding showed an association with ADHD symptoms (OR = 0.68, 95% CI: 0.48-0.95) while exclusive breastfeeding did not (OR = 1.00, 95% CI: 0.66-1.55). In conclusion, our findings suggest that prenatal maternal stress increases the risk of more severe forms of ADHD symptoms in the offspring and breastfeeding can protect against such symptoms at the ages of 8 and 16.

Temporal patterns in adolescent psychiatric treatment and outcomes: a nationwide register-based cohort follow-up.

The rise in mental health problems among adolescents in high-income countries presents a challenge to service systems. For the development of services, there is a need for better insight into temporal psychiatric treatment-trends and outcomes. This study aims to analyze time-trends in both psychiatric treatment patterns and outcomes, utilizing a national sample of all adolescents receiving psychiatric treatment in Finland from 2003 to 2013. For time-trend-analysis, the sample was divided into two cohorts, using the onset year of 2008 as a cutoff. For each case, information on psychiatric treatment was gathered from registers within a five-year follow-up period from the onset of treatment or to death. The association between the inclusion year and outcome variables was studied via weighted generalized linear models. Adolescents in the latter cohort had a greater proportion (p < 0.001) of mood and anxiety diagnoses, a lower likelihood of hospitalization, a higher average of outpatient visits, and greater usage of psychotropics (excluding benzodiazepines). Those whose treatment began after 2008 were more likely to be alive (baseline characteristic adjusted Odds Ratio (aOR): 0.7, 95%CI: 0.6-0.8) and still in treatment contact (aOR: 1.4, 95%CI: 1.3-1.4) after four years from the onset. There was no difference in the long-term disability ratio. The results indicate favorable developments towards outpatient care in mental health services for adolescents with a significant decrease in mortality. Approaches to further developing cost-effective, personalized mental health services are discussed.

Developmental origins of psycho-cardiometabolic multimorbidity in adolescence and their underlying pathways through methylation markers: a two-cohort study.

Understanding the biological mechanisms behind multimorbidity patterns in adolescence is important as they may act as intermediary risk factor for long-term health. We aimed to explore relationship between prenatal exposures and adolescent's psycho-cardiometabolic intermediary traits mediated through epigenetic biomarkers, using structural equation modeling (SEM). We used data from mother-child dyads from pregnancy and adolescents at 16-17 years from two prospective cohorts: Northern Finland Birth Cohort 1986 (NFBC1986) and Raine Study from Australia. Factor analysis was applied to generate two different latent factor structures: (a) prenatal exposures and (b) adolescence psycho-cardiometabolic intermediary traits. Furthermore, three types of epigenetic biomarkers were included: (1) DNA methylation score for maternal smoking during pregnancy (DNAmMSS), (2) DNAm age estimate PhenoAge and (3) DNAm estimate for telomere length (DNAmTL). Similar factor structure was observed between both cohorts yielding three prenatal factors, namely BMI (Body Mass Index), SOP (Socio-Obstetric-Profile), and Lifestyle, and four adolescent factors: Anthropometric, Insulin-Triglycerides, Blood Pressure, and Mental health. In the SEM pathways, stronger direct effects of F1prenatal-BMI (NFBC1986 = ß: 0.27; Raine = ß: 0.39) and F2prenatal-SOP (ß: -0.11) factors were observed on adolescent psycho-cardiometabolic multimorbidity. We observed an indirect effect of prenatal latent factors through epigenetic markers on a psycho-cardiometabolic multimorbidity factor in Raine study (P < 0.05). The present study exemplifies an evidence-based approach in two different birth cohorts to demonstrate similar composite structure of prenatal exposures and psycho-cardiometabolic traits (despite cultural, social, and genetic differences) and a common plausible pathway between them through underlying epigenetic markers.

Association of temperament and character traits with ADHD and its comorbidities.

BACKGROUND: Increasing evidence suggests that personality traits may be associated with ADHD and comorbid concerns. We investigated temperament and character traits associated with internalizing and externalizing comorbidities in adolescents with or without ADHD. METHODS: The population consisted of a subsample (n = 457) of the Northern Finland Birth Cohort 1986 (NFBC1986) that comprised 16-year-old adolescents with and without symptoms of ADHD. ADHD and psychiatric comorbidities were assessed using the Kiddie-SADS-PL and temperament and character profiles were determined with TCI-125. Outcomes were examined using Pearson's chi-square test, Analyses of Covariance and Cohen's d. RESULTS: The adolescents with ADHD endorsed more novelty seeking and less persistence, self-directedness, and cooperativeness than those without. Comparison of the personality traits and psychiatric comorbidities with the ADHD cases showed that comorbidities did not particularly affect the temperament and character profiles, but rather ADHD accounted for the differences between the personality traits. However, the temperament and character traits predicted externalizing and internalizing psychiatric disorders in the control group. CONCLUSIONS: Our findings reveal unique comorbidity-related temperament factors, which may have implications for adaptive and personalizing intervention efforts.

Functioning, psychiatric symptoms and quality of life of individuals with severe mental disorders after psychiatric rehabilitation.

PURPOSE: Psychiatric disorders may have a negative effect on individuals' living, forming intimate relationships, education, and employment. The aim of psychiatric rehabilitation is to promote recovery - finding ways to cope with mental disorders despite debilitating symptoms. This study aimed to explore the outcomes of accommodation, social inclusion, psychiatric symptoms, substance and service use, quality of life and subjective recovery of young adults with severe mental illness after psychiatric rehabilitation. MATERIALS AND METHODS: The study population consisted of individuals who had been in residential psychiatric rehabilitation between the ages of 18-29 years. Data on outcomes were collected using a questionnaire after a flexible follow-up period (mean 29 months). The questionnaire was answered by 32 eligible persons. We analysed multiple outcomes and compared the proportion of persons living independently at the start, after psychiatric rehabilitation, and at the follow-up point. RESULTS: At the start of the rehabilitation, 33%, at the end, 69%, and at follow-up, 78% lived independently. However, most had not reached competitive employment nor were studying. Cognitive symptoms were the most common psychiatric symptoms, followed by depressive symptoms. More than 80% of the sample felt that they had partly recovered from their severe mental illness. CONCLUSION: According to the results of this study residential psychiatric rehabilitation may have positive effects on functioning and independent living at follow-up. Reaching competitive employment is difficult for persons with severe mental disorders and effective rehabilitation interventions need to be implemented. However, this study had limitations, and these results should be considered preliminary.

Body mass index in the middle-aged offspring of parents with severe mental illness.

BACKGROUND: People with severe mental illness (SMI) have an elevated risk of obesity but the causes and mechanisms are unclear. We explored the familial association between parental SMI and body mass index (BMI) in middle-aged offspring. Our objective was to determine if the offspring of either parent with SMI have an increased risk for obesity. METHODS: The Northern Finland Birth Cohort 1966 is a cohort study of offspring with expected date of birth in 1966. The data include originally 12 068 mothers and 12 231 children from the provinces of Lapland and Oulu in Finland. The final study sample included 5050 middle-aged offspring. Parental SMI was used as exposure in the study. BMI measured at the age of 46 years was used as a primary outcome. RESULTS: Risk for obesity was elevated in the offspring of mothers with SMI [overweight: adjusted odds ratio (OR) 1.93 (1.29-2.90), obese class I: 1.97 (1.20-3.25), obese classes II-III: 2.98 (1.67-5.33)]. For the offspring of either parent with SMI, statistically significant results were found in obese class I and obese classes II-III [overweight: adjusted OR 1.21 (0.94-1.54), obese class I: 1.52 (1.03-1.08), obese classes II-III: 1.53 (1.01-2.32)]. CONCLUSIONS: We found an elevated risk of obesity in the middle-aged offspring of either parent with SMI, especially in the offspring of mothers with SMI. Thus, there might be a common familial pathway leading to the co-occurrence of obesity and SMI.

Attention deficit hyperactivity and oppositional defiant disorder symptoms in adolescence and risk of substance use disorders-A general population-based birth cohort study.

BACKGROUND: Externalizing symptoms are associated with risk of future substance use disorder (SUD). Few longitudinal studies exist using general population-based samples which assess the spectrum of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms. AIMS/OBJECTIVES: We aimed to study the associations between adolescent ADHD symptoms and subsequent SUD and additionally examine whether the risk of SUD is influenced by comorbid oppositional defiant disorder (ODD) symptoms. METHODS: The Northern Finland Birth Cohort 1986 was linked to nationwide health care register data for incident SUD diagnoses until age 33 years (n = 6278, 49.5% male). ADHD/ODD-case status at age 16 years was defined using parent-rated ADHD indicated by Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) questionnaire with 95% percentile cut-off. To assess the impact of ODD comorbidity on SUD risk, participants were categorized into four groups based on their ADHD/ODD case status. Cox-regression analysis with hazard ratios (HRs) and 95% confidence intervals (CIs) were used to study associations between adolescent ADHD/ODD case statuses and subsequent SUD. RESULTS: In all, 552 participants (8.8%) presented with ADHD case status at the age of 16 years, and 154/6278 (2.5%) were diagnosed with SUD during the follow-up. ADHD case status was associated with SUD during the follow-up (HR = 3.84, 95% CI 2.69-5.50). After adjustments for sex, family structure, and parental psychiatric disorder and early substance use the association with ADHD case status and SUD remained statistically significant (HR = 2.60, 95% CI 1.70-3.98). The risk of SUD remained elevated in individuals with ADHD case status irrespective of ODD symptoms. CONCLUSIONS: ADHD in adolescence was associated with incident SUD in those with and without symptoms of ODD. The association of ADHD and SUD persisted even after adjustment for a wide range of potential confounds. This emphasizes the need to identify preventative strategies for adolescents with ADHD so as to improve health outcomes.

Measures of Early-life Behavior and Later Psychopathology in the LifeCycle Project - EU Child Cohort Network: A Cohort Description.

BACKGROUND: The EU LifeCycle Project was launched in 2017 to combine, harmonize, and analyze data from more than 250,000 participants across Europe and Australia, involving cohorts participating in the EU-funded LifeCycle Project. The purpose of this cohort description is to provide a detailed overview of the major measures within mental health domains that are available in 17 European and Australian cohorts participating in the LifeCycle Project. METHODS: Data on cognitive, behavioral, and psychological development has been collected on participants from birth until adulthood through questionnaire and medical data. We developed an inventory of the available data by mapping individual instruments, domain types, and age groups, providing the basis for statistical harmonization across mental health measures. RESULTS: The mental health data in LifeCycle contain longitudinal and cross-sectional data from birth throughout the life course, covering domains across a wide range of behavioral and psychopathology indicators and outcomes, including executive function, depression, ADHD, and cognition. These data span a unique combination of qualitative data collected through behavioral/cognitive/mental health questionnaires and examination, as well as data from biological samples and indices in the form of imaging (MRI, fetal ultrasound) and DNA methylation data. Harmonized variables on a subset of mental health domains have been developed, providing statistical equivalence of measures required for longitudinal meta-analyses across instruments and cohorts. CONCLUSION: Mental health data harmonized through the LifeCycle project can be used to study life-course trajectories and exposure-outcome models that examine early life risk factors for mental illness and develop predictive markers for later-life disease.

Premorbid temperament as predictor of onset of depression: 23-year follow-up.

BACKGROUND: Previously Cloninger's temperament traits have been researched as a risk factor for depression mostly in cross-sectional studies. In these studies, especially high harm avoidance has been associated with an increased risk of depression. The main objective of this study was to investigate how temperament traits affect the risk of the onset of depression in a previously mentally healthy adult population. METHODS: This study includes a follow-up period of 23 years from the age of 31 until 54 in the Northern Finland Birth Cohort 1966 Study. Temperament was measured at the 31-year follow-up using Temperament and Character Inventory (TCI). The outcome of the study was depressive disorder diagnosis during the follow-up in both sexes. To be able to take correlations between temperament traits we also did an analysis using temperament clusters. RESULTS: Our sample size was 3999 individuals, out of which 240 were diagnosed with depression. For women an increase in the TCI score for novelty seeking (NS), harm avoidance (HA) or persistence (P) increased the risk of depression during the follow-up. For men only HA was a significant predictor of depression. An increase in reward dependence (RD) was found to reduce the risk of psychotic depression. In the analysis using the temperament clusters, the cluster including shy and pessimistic individuals was associated with risk for depression diagnosis in men. CONCLUSIONS: This prospective general population-based cohort study added to previous knowledge of high HA being a risk factor for depression, but it also found new associations such as higher P and NS.

Temperament and longitudinal changes in physical activity - the Northern Finland Birth Cohort 1966 Study.

BACKGROUND: Insufficient physical activity is risk factor for morbidity and premature mortality. This population-based birth cohort study investigated the cross-sectional and longitudinal associations between self-reported temperament at age 31 and self-reported leisure-time moderate to vigorous physical activity (MVPA) levels and changes thereof from the age of 31 to the age of 46 years. METHODS: The study population comprised 3,084 subjects (1,359 male and 1,725 female) from the Northern Finland Birth Cohort 1966. MVPA was self-reported at ages 31 and 46 years. Novelty seeking, harm avoidance, reward dependence, and persistence and their subscales were measured using Cloninger's Temperament and Character Inventory at age 31. Four temperament clusters were used in the analyses: persistent, overactive, dependent, and passive. Logistic regression was used to evaluate the relationship between temperament and MVPA. RESULTS: The persistent and overactive temperament profiles at age 31 were positively associated with higher MVPA levels both in young adulthood and in midlife, while the passive and dependent temperament profiles were associated with lower MVPA levels. The overactive temperament profile was associated with a decrease in MVPA levels from young adulthood to midlife among males. CONCLUSION: A passive temperament profile characterized by high harm avoidance is associated with a higher risk of low MVPA level than other temperament profiles over the life cycle in females. The results suggest that temperament may play a role in determining the level and sustainability of MVPA. Individual targeting and intervention tailoring for promoting physical activity should consider temperament traits.

Adolescent alcohol and cannabis use as risk factors for head trauma in the Northern Finland Birth Cohort study 1986.

BACKGROUND: The aim of this study was to assess the associations between cannabis use and frequency of alcohol intoxication in adolescence with the risk of traumatic brain injury and craniofacial fractures in early adulthood. Hypothesis was that using alcohol and cannabis in adolescence could increase the risk for head traumas. METHODS: Data from the Northern Finland Birth Cohort 1986 (n = 9432 individuals) were used to investigate the prospective association between the self-reported frequency of alcohol intoxication (n = 6472) and cannabis use (n = 6586) in mid-adolescence and register-based, head trauma diagnoses by ages 32-33 years. To test the robustness of these associations, the statistical models were adjusted for a range of other confounders such as illicit drug use, previous head trauma and self-reported mental health problems. RESULTS: In multivariate analyses, cannabis use was statistically significantly associated with a greater risk of traumatic brain injury among females [hazard ratio (HR) 1.9, 95% confidence interval (CI) 1.1-3.2, P = 0.024). Frequent alcohol intoxication was a statistically significant independent risk factor for both traumatic brain injury (HR 2.6, 95% CI 1.7-3.9, P < 0.001) and craniofacial fractures (HR 2.7, 95% CI 1.6-4.8, P < 0.001) among males. CONCLUSIONS: Cannabis use in adolescence appears to associate independently with elevated risk for traumatic brain injury among females, and frequent alcohol intoxication in adolescence seems to associate with elevated risk of both traumatic brain injury and craniofacial fractures among males.

Employment trajectories until midlife in schizophrenia and other psychoses: the Northern Finland Birth Cohort 1966.

PURPOSE: Psychoses are associated with poor labour market attachment, but few studies have compared schizophrenia (SZ) and other psychoses (OP). Moreover, studies on long-term employment trajectories over individuals' working life courses are lacking. We compared 30 year employment trajectory patterns in a general population sample among individuals with SZ, OP, and those with no psychosis (NP). METHODS: Utilising the Northern Finland Birth Cohort 1966, we collected survey data on employment from ages 16 to 45 and detected individuals with register-based history of SZ (n = 62), OP (n = 87), or NP (n = 6464) until age 46. Through gender-specific latent class analyses on annual employment roles, we identified traditional, highly educated, self-employed, delayed and floundering employment trajectories with distinct socioeconomic characteristics. We addressed attrition by conducting weighted analyses. RESULTS: Floundering trajectories were common among individuals with SZ (79% of men, 73% of women) and OP (52% of men, 51% of women). In NP, a traditional employee trajectory was most common in men (31%), and a highly educated trajectory in women (28%). A history of psychosis was associated with heightened odds ratios (ORs; 95% confidence intervals (CIs)) for floundering trajectories in both men (SZ: 32.9 (13.3-81.4); OP: 7.4 (4.0-13.9)) and women (SZ: 9.9 (4.6-21.5); OP: 3.9 (2.1-7.1)) compared to NP. Weighted analyses produced similar results. CONCLUSION: Most individuals with SZ or OP have floundering employee trajectories reflecting an elevated risk of unemployment and part-time work until midlife. These results indicate the importance of improving labour market attachment during the early phases of psychoses.

The effectiveness of digital gaming on the functioning and activity of older people living in long-term care facilities: a systematic review and meta-analysis.

BACKGROUND: The population is aging globally. Older people living in long-term care facilities have many functional impairments, such as mobility problems and depression. Digital games and so-called exergames can offer a motivating and entertaining way to maintain older people's physical activity and thus their ability to function. However, previous studies have reported conflicting results about the effects of digital gaming and have focused on community-dwelling older people. OBJECTIVE: To identify, critically appraise, and synthesize evidence about the effectiveness of digital games on older people's physical, psychological, and social functioning and physical and social activity in long-term care facilities. METHODS: Five databases were systematically searched, and relevant studies were screened. Fifteen randomized-controlled trials and quasi-experimental studies (total N = 674) were included in meta-analysis. RESULTS: All digital games used in interventions were exergames. Meta-analysis showed that exergame interventions have a statistically significant large effect on physical functioning [number of studies (N) = 6, standardized mean difference (SMD) = 0.97, p = 0.001] measured by Timed Up and Go or Short Physical Performance Battery and self-assessed physical activity (N = 3, SMD = 1.20, p < 0.001) and medium effect on social functioning (N = 5, SMD = 0.74, p = 0.016) compared to alternative intervention or no intervention. Social activity was not measured in any study. CONCLUSIONS: The results are encouraging that exergames effectively increase the functioning and activity of older adults living in long-term facilities. Successful implementation of such activities requires the competence of nursing staff and rehabilitation professionals in digitalization.

Effect of onset age on the long-term outcome of early-onset psychoses and other mental disorders: a register-based Northern Finland Birth Cohort 1986 study.

Psychiatric illnesses can affect the social transitions of adolescence and young adulthood, such as completing education and entering working life and relationships. However, associations between earlier onset age and long-term outcomes among those with early-onset psychoses (EOP) are unclear, as are the long-term outcomes of EOP compared to non-psychotic disorders. We used national register data of the Northern Finland Birth Cohort 1986 to detect persons with EOP and other early-onset psychiatric disorders. The long-term clinical and work-family outcomes of persons with onset age before 18 years (n = 41 psychoses, n = 495 non-psychoses) or between 18-22 years (n = 61 psychoses, n = 377 non-psychoses) were compared. Individuals with the onset of psychosis between 18-22 years had significantly more unfavourable long-term outcomes when compared to those with psychosis onset before 18 years. Persons with psychosis onset before the age of 18 years had similar outcomes to those with non-psychotic psychiatric disorder onset before 18 years regarding educational level, marital status, having children, and substance use disorders. Individuals with EOP were more often on a disability pension compared to those with other early-onset mental disorders. Adjusting for sex, educational level and substance use only slightly diluted these results. Unexpectedly, later onset age of EOP was associated with worse outcomes. Those with psychosis onset between 18-22 years of age are in a critical period, which underlines the importance of investing on interventions in this age group. Further studies on the effect of the onset age on later outcomes in EOP are needed.
