  • Poor Family Relationships in Adolescence and the Risk of Premature Death : Findings from the Stockholm Birth Cohort Study
  • 2019
  • In: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 16:10
  • Journal article (peer-reviewed)abstract
    • Poor family relationships during childhood have been shown to have long-term negative effects on an offspring's health. However, few studies have followed the offspring to retirement age, and relatedly, knowledge about the link between poor family relationships and premature death is scarce. The aim of this study was to examine the association between poor family relationships in adolescence and the risk of premature death, even when considering other adverse childhood conditions. Prospective data from the Stockholm Birth Cohort study were used, with 2636 individuals born in 1953 who were followed up until age 65. Information on family relations was based on interviews with the participants' mothers in 1968. Information on mortality was retrieved from administrative register data from 1969-2018. Cox proportional hazards regressions showed that poor family relationships in adolescence were associated with an increased risk of premature death, even when adjusting for childhood conditions in terms of household social class, household economic poverty, contact with the child services, parental alcohol abuse, and parental mental illness (Hazard Ratio (HR), 2.08, 95% Confidence Interval (CI), 1.40-3.09). The findings show that poor family relationships in adolescence can have severe and long-lasting health consequences, highlighting the importance of early interventions.

  • Poor family relationships in adolescence as a risk factor of in-patient psychiatric care across the life course : A prospective cohort study
  • 2020
  • In: Scandinavian Journal of Public Health. - Stockholm : Sage Publications. - 1403-4948 .- 1651-1905. ; 48:7, s. 726-732
  • Journal article (peer-reviewed)abstract
    • Background: Previous research has shown that poor family relations in childhood are associated with adverse mental health in adulthood. Yet, few studies have followed the offspring until late adulthood, and very few have had access to register-based data on hospitalisation due to psychiatric illness. The aim of this study was to examine the association between poor family relations in adolescence and the likelihood of in-patient psychiatric care across the life course up until age 55. Methods: Data were derived from the Stockholm Birth Cohort study, with information on 2638 individuals born in 1953. Information on family relations was based on interviews with the participants' mothers in 1968. Information on in-patient psychiatric treatment was derived from administrative registers from 1969 to 2008. Binary logistic regression was used. Results: Poor family relations in adolescence were associated with an increased risk of later in-patient treatment for a psychiatric diagnosis, even when adjusting for other adverse conditions in childhood. Further analyses showed that poor family relations in adolescence were a statistically significant predictor of in-patient psychiatric care up until age 36-45, but that the strength of the association attenuated over time. Conclusions: Poor family relationships during upbringing can have serious negative mental-health consequences that persist into mid-adulthood. However, the effect of poor family relations seems to abate with age. The findings point to the importance of effective interventions in families experiencing poor relationships.

  • Poor family relationships in adolescence as a risk factor of in-patient somatic care across the life course : Findings from a 1953 cohort
  • 2021
  • In: SSM - Population Health. - : Elsevier. - 2352-8273. ; 14
  • Journal article (peer-reviewed)abstract
    • Background: Prior research has shown that poor family relations during upbringing have long-term detrimental effects on mental health. Few previous studies have, however, focused on somatic health outcomes and studies rarely cover the life span until retirement age. The aims of the current study were, firstly, to examine the association between poor family relationships in adolescence and in-patient somatic care across the life course whilst adjusting for confounders at baseline and concurrent psychiatric in-patient care; and secondly, to compare the risks of somatic and psychiatric in-patient care across the life course.Methods: Prospective data from the Stockholm Birth Cohort study were used, with 2636 participants born in 1953 who were followed up until 2016. Information on family relationships was collected from the participants' mothers in 1968. Annual information on in-patient somatic and psychiatric care was retrieved from official register data from 1969 to 2016.Results: Poisson regressions showed that poor family relationships in adolescence were associated with an increased risk of in-patient somatic care in mid- and especially in late adulthood (ages 44-53 and 54-63 years), even when controlling for the co-occurrence of psychiatric illness and a range of childhood conditions. No statistically significant association was observed in early adulthood (ages 16-43 years), when controlling for confounders. These findings are in sharp contrast to the analyses of inpatient psychiatric care, according to which the association with poor family relations was strongest in early adulthood and thereafter attenuated across the life course.Conclusion: Poor family relationships in adolescence are associated with an increased risk of severe consequences for somatic health lasting to late adulthood even when controlling for confounders including in-patient psychiatric care, emphasising the potentially important role of early interventions.

  • In vivo white matter microstructure in adolescents with early-onset psychosis : a multi-site mega-analysis
  • 2023
  • In: Molecular Psychiatry. - : Springer Nature. - 1359-4184 .- 1476-5578. ; 28, s. 1159-1169
  • Journal article (peer-reviewed)abstract
    • Emerging evidence suggests brain white matter alterations in adolescents with early-onset psychosis (EOP; age of onset <18 years). However, as neuroimaging methods vary and sample sizes are modest, results remain inconclusive. Using harmonized data processing protocols and a mega-analytic approach, we compared white matter microstructure in EOP and healthy controls using diffusion tensor imaging (DTI). Our sample included 321 adolescents with EOP (median age=16.6 years, interquartile range (IQR)=2.14, 46.4% females) and 265 adolescent healthy controls (median age=16.2 years, IQR=2.43, 57.7% females) pooled from nine sites. All sites extracted mean fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) for 25 white matter regions of interest per participant. ComBat harmonization was performed for all DTI measures to adjust for scanner differences. Multiple linear regression models were fitted to investigate case-control differences and associations with clinical variables in regional DTI measures. We found widespread lower FA in EOP compared to healthy controls, with the largest effect sizes in the superior longitudinal fasciculus (Cohen's d=0.37), posterior corona radiata (d=0.32), and superior fronto-occipital fasciculus (d=0.31). We also found widespread higher RD and more localized higher MD and AD. We detected significant effects of diagnostic subgroup, sex, and duration of illness, but not medication status. Using the largest EOP DTI sample to date, our findings suggest a profile of widespread white matter microstructure alterations in adolescents with EOP, most prominently in male individuals with early-onset schizophrenia and individuals with a shorter duration of illness.

  • Clozapine protects adult neural stem cells from ketamine-induced cell death in correlation with decreased apoptosis and autophagy.
  • 2010
  • In: Bioscience Reports. - Portland. - 0144-8463 .- 1573-4935. ; 31:40
  • Journal article (peer-reviewed)abstract
    • Adult neurogenesis, the production of newborn neurons from neural stem cells (NSCs) has been suggested to be decreased in patients with schizophrenia. A similar finding was observed in an animal model of schizophrenia, as indicated by decreased bromodeoxyuridine (BrdU) labelling cells in response to a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist. The antipsychotic drug clozapine was shown to counteract the observed decrease in BrdU-labelled cells in hippocampal dentate gyrus (DG). However, phenotypic determination by immunohistochemistry analysis could not reveal whether BrdU-positive cells were indeed NSCs. Using a previously established cell model for analysing NSC protection in vitro, we investigated a protective effect of clozapine on NSCs. Primary NSCs were isolated from the mouse subventricular zone (SVZ), we show that clozapine had a NSC protective activity alone, as evident by employing an ATP cell viability assay. In contrast, haloperidol did not show any NSC protective properties. Subsequently, cells were exposed to the non-competitive NMDA-receptor antagonist ketamine. Clozapine, but not haloperidol, had a NSC protective/anti-apoptotic activity against ketamine-induced cytotoxicity. The observed NSC protective activity of clozapine was associated with increased expression of the anti-apoptotic marker Bcl-2, decreased expression of the pro-apoptotic cleaved form of caspase-3 and associated with decreased expression of the autophagosome marker 1A/1B-light chain 3 (LC3-II). Collectively, our findings suggest that clozapine may have a protective/anti-apoptotic effect on NSCs, supporting previous in vivo observations, indicating a neurogenesis-promoting activity for clozapine. If the data are further confirmed in vivo, the results may encourage an expanded use of clozapine to restore impaired neurogenesis in schizophrenia.

  • Long term follow up of adolescent depression : a population based study
  • 2010
  • In: Upsala Journal of Medical Sciences. - : Uppsala Medical Society. - 0300-9734 .- 2000-1967. ; 115:1, s. 21-29

    • Adolescent depression is common. Earlier studies indicate that relapses and recurrences are common. But many questions are still unanswered. The aim of the present study has been to follow subjects with adolescent depressions, identified in a population-based study, over a 15-year period. Subjects with adolescent depression (n = 362) and a comparison group (n = 250) were followed in the National Swedish registers.The formerly depressed females had significantly more out-patient visits, and a significantly higher proportion (78.4% versus 69.6%) had at least one out-patient visit. Among the males, no significant differences were found as concerns out-patient visits. The formerly depressed females had significantly more in-patient stays (3.6 versus 2.4) and a significantly higher total number of in-patient days (27.4 versus 10.1). A significantly higher proportion had in-patient days due to mental disorders (9.5% versus 4.6%), in particular anxiety disorders (4.9% versus 1.0%). As concerns the males, a significantly higher proportion had in-patient days due to mental disorders (16.5% versus 1.8%), in particular alcohol and drug abuse (7.6% versus 0%).Among the formerly depressed females there were no significant differences against the comparison group as concerns the proportion of being a mother, number of children per woman, or age at first child. However, a significantly higher proportion of the formerly depressed females had had different, usually mild, disorders related to pregnancy (8.6% versus 0.6%). The children of the women with adolescent depressions were not affected.

  • Preclinical atherosclerosis in adolescents with psychotic or bipolar disorders investigated with carotid high-frequency ultrasound.
  • 2020
  • In: Brain and Behavior. - : Wiley. - 2162-3279. ; 10:12
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: Early-onset psychosis (EOP) and bipolar disorder (EOBP) (at <18 years of age), are associated with an increased future risk of cardiovascular disease (CVD) and premature death. Yet it is unknown whether the arteries show visible signs of atherosclerosis in EOP and EOBP. This study investigated whether having EOP or EOBP was associated with detectable signs of preclinical atherosclerosis.METHOD: By using 22 MHz high-frequency ultrasound, different layers of the arterial wall of the left common carotid artery (LCCA) were assessed in 77 individuals with EOP (n = 25), EOBP (n = 22), and in age-matched healthy controls (n = 30). Conventional CVD confounders were included in the analyses.RESULTS: Adolescents with EOP and EOBP, compared to controls, had a significantly thicker LCCA intima thickness (0.132 vs. 0.095 mm, p < .001) and intima/media ratio (0.24 vs. 0.17 p < .001). There was a nonsignificant intima difference between EOP and EOBP. Conventional CVD risk factors did not explain the association between EOP/EOBP and intima thickness. In the group of EOP/EOBP, there was a significant correlation between the dose of current antipsychotic medication and intima thickness; however, the correlation was attenuated to a nonsignificant level when adjusted for global function.CONCLUSIONS: Adolescents with EOP or EOBP had an increased LCCA intima thickness, interpreted as a sign of preclinical atherosclerosis. Global function of the disorders was the strongest determinant of intima thickness. The findings, if replicated, might have implications for long-term treatment of EOP and EOBP in order to reduce a future risk of CVD.

  • Prognostic significance of functional somatic symptoms in adolescence : a 15-year community-based follow-up study of adolescents with depression compared with healthy peers
  • 2012
  • In: BMC Psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 12, s. 90-
  • Journal article (peer-reviewed)abstract
    • BackgroundThere is a lack of population-based long-term longitudinal research on mental health status and functional physical/somatic symptoms. Little is known about the long-term mental health outcomes associated with somatic symptoms or the temporal relationship between depression and such symptoms. This 15-year study followed up adolescents with depression and matched controls, screened from a population-based sample, who reported different numbers of somatic symptoms.MethodsThe total population of 16–17-year-olds in Uppsala, Sweden, was screened for depression in 1991–1993. Adolescents who screened positive and an equal number of healthy controls took part in a semi-structured diagnostic interview. In addition, 21 different self-rated somatic symptoms were assessed. Sixty-four percent of those adolescents participated in a follow-up structured interview 15 years later.ResultsSomatic symptoms in adolescence predicted depression and other adult mental disorders regardless of the presence of adolescent depression. In adolescents with depression, the number of functional somatic symptoms predicted, in a dose response relationship, suicidal behavior, bipolar episodes, and psychotic episodes as well as chronic and recurrent depression. Contrary to expectations, the somatic symptoms of abdominal pain and perspiration without exertion better predicted depression than all DSM-IV depressive symptoms. Abdominal pain persisted as an independent strong predictor of depression and anxiety, even after controlling for other important confounders.ConclusionsSomatic symptoms in adolescence can predict severe adult mental health disorders. The number of somatic symptoms concurrent with adolescent depression is, in a stepwise manner, linked to suicidal attempts, bipolar disorders, psychotic disorders, and recurrent and chronic depression. These findings can be useful in developing treatment guidelines for patients with somatic symptoms.

  • Thicker carotid intima layer, thinner media layer and higher intima/media ratio in women with recurrent depressive disorders : a pilot study using non-invasive high frequency ultrasound
  • 2010
  • In: World Journal of Biological Psychiatry. - : Informa Healthcare. - 1562-2975 .- 1814-1412. ; 11:1, s. 71-75
  • Journal article (peer-reviewed)abstract
    • Background. Growing evidence indicates that depression is an important risk factor for coronary heart disease. Thus, the aim of the present study has been to investigate if young women with adolescent onset and recurrent depressive disorders have signs of carotid intima and media changes already at the age of 30. Methods. Fifteen subjects with adolescent onset recurrent depressive disorders, mean age 31.5 years, were compared to 20 healthy women with a mean age of 39.6 years. The thickness of carotid artery intima and media was assessed, using non-invasive high-frequency ultrasound (25MHz). Results. The subjects with recurrent depressive disorders had significantly thicker carotid intima, significantly thinner carotid media and significantly higher intima/media ratio despite the fact that they were about 10 years younger than the healthy women. Hypertension, obesity or smoking could not explain the results. Conclusion. Already at the age of 30, subjects with recurrent depressive disorders with adolescent onset do have early signs of carotid intima and media changes, indicating a less healthy artery wall, despite otherwise no clinical signs of cardiovascular disease.
