- PURPOSE: Depression at all ages is recognized as a global public health concern, but less is known about the welfare burden following early-life depression. This study aimed to (1) estimate the magnitude of associations between depression in adolescence and social transfer payments in adulthood; and (2) address the impact of major comorbid psychopathology on these associations.METHODS: This is a longitudinal cohort study of 539 participants assessed at age 16-17 using structured diagnostic interviews. An ongoing 25-year follow-up linked the cohort (n = 321 depressed; n = 218 nondepressed) to nationwide population-based registries. Outcomes included consecutive annual data on social transfer payments due to unemployment, work disability, and public assistance, spanning from age 18 to 40. Parameter estimations used the generalized estimating equations approach.RESULTS: Adolescent depression was associated with all forms of social transfer payments. The estimated overall payment per person and year was 938 USD (95% CI 551-1326) over and above the amount received by nondepressed controls. Persistent depressive disorder was associated with higher recipiency across all outcomes, whereas the pattern of findings was less clear for subthreshold and episodic major depression. Moreover, depressed adolescents presenting with comorbid anxiety and disruptive behavior disorders evidenced particularly high recipiency, exceeding the nondepressed controls with an estimated 1753 USD (95% CI 887-2620).CONCLUSION: Adolescent depression is associated with considerable public expenditures across early-to-middle adulthood, especially for those exposed to chronic/persistent depression and psychiatric comorbidities. This finding suggests that the clinical heterogeneity of early-life depression needs to be considered from a longer-term societal perspective.

Adulthood Outcomes of Child and Adolescent Depression : From Mental Health to Social Functioning
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Depression is a common mental disorder affecting people across the lifespan, with first onset frequently occurring in the teenage years. The disorder is costly to society and constitutes one of the leading causes of disability in youths and adults worldwide. Research demonstrates that depression in childhood or adolescence is linked to adverse adult consequences, including mental health problems, physical health issues, various social difficulties, and economic hardships. While the specific factors and mechanisms associated with these long-term adversities are not well understood, previous studies point to the relevance of considering the heterogeneity in early-life depression.The overarching aim of this doctoral thesis was to shed more light on long-term outcomes of childhood and adolescent depression across multiple life domains. This work made use of extensive follow-up data gathered in Sweden and USA, as part of two community-based longitudinal cohort studies of depressed and nondepressed youths prospectively followed into adulthood. In the Uppsala Longitudinal Adolescent Depression Study, participants were interviewed around age 16 (n=631) and age 31 (n=409). Using linkage to nationwide population-based registries, participants were followed up around age 40 (n=576). In the Great Smoky Mountains Study, participants were interviewed at repeated occasions in childhood and adolescence (n=1,420), and at further follow-ups in adulthood extending up to age 30 (n=1,336).Findings from this work suggest that childhood/adolescent depression can have long-lasting associations with a broad spectrum of adverse outcomes. First, the risk of adult depression is known to be elevated among those exposed to depression in early life; however, depressed youths experiencing major conflicts with parents may be at an additionally increased risk of subsequent depression recurrence. Second, early-life depression was found to be associated with higher levels of adult psychiatric disorders, and also with worse health, criminal, and social functioning, even when accounting for a multitude of potential confounders. Third, early-life depression was predictive of poor labor market outcomes, especially for those with persistent depression. This link was partially mediated by the course of depression. Fourth, the welfare burden associated with early depression amounted to considerable public expenditures in adulthood, particularly for those with persistent depression or comorbid psychiatric conditions such as anxiety and disruptive behavior disorders.The adverse long-term consequences in the wake of early-life depression underscore the importance of prevention and treatment approaches that are both efficacious and cost-effective. Such targeted efforts may have the potential to avert later ill-health, impairment, and possibly also economic disadvantage.

- Purpose: To present the Uppsala Longitudinal Adolescent Depression Study, initiated in Uppsala, Sweden, in the early 1990s. The initial aim of this epidemiological investigation was to study the prevalence, characteristics and correlates of adolescent depression, and has subsequently expanded to include a broad range of social, economic and health-related long-term outcomes and cost-of-illness analyses.Participants: The source population was first-year students (aged 16-17) in upper-secondary schools in Uppsala during 1991-1992, of which 2300 (93%) were screened for depression. Adolescents with positive screening and sex/age-matched peers were invited to a comprehensive assessment. A total of 631 adolescents (78% females) completed this assessment, and 409 subsequently completed a 15year follow-up assessment. At both occasions, extensive information was collected on mental disorders, personality and psychosocial situation. Detailed social, economic and health-related data from 1993 onwards have recently been obtained from the Swedish national registries for 576 of the original participants and an age-matched reference population (N=200 000).Findings to date: The adolescent lifetime prevalence of a major depressive episode was estimated to be 11.4%. Recurrence in young adulthood was reported by the majority, with a particularly poor prognosis for those with a persistent depressive disorder or multiple somatic symptoms. Adolescent depression was also associated with an increased risk of other adversities in adulthood, including additional mental health conditions, low educational attainment and problems related to intimate relationships.Future plans: Longitudinal studies of adolescent depression are rare and must be responsibly managed and utilised. We therefore intend to follow the cohort continuously by means of registries. Currently, the participants are approaching mid-adulthood. At this stage, we are focusing on the overall long-term burden of adolescent depression. For this purpose, the research group has incorporated expertise in health economics. We would also welcome extended collaboration with researchers managing similar datasets.

- Adolescent depression is linked to adult ill-health and functional impairment, but recent research suggests that individual/contextual factors might account for this association. This study aimed to test whether the clinical heterogeneity of adolescent depression is related to marginalization from the labor market across early to middle adulthood. Data were drawn from the Uppsala Longitudinal Adolescent Depression Study, a community-based cohort initially assessed with structured clinical interviews at age 16-17. The cohort (n = 321 depressed; n = 218 nondepressed) was followed up after 2+ decades through linkage to nationwide population-based registries. Outcomes included consecutive annual data on unemployment, work disability, social welfare recipiency, and a composite marginalization measure, spanning from age 21 to 40. Longitudinal associations were examined using logistic regression analysis in a generalized estimating equations modeling framework. Subsequent depressive episodes and educational attainment in early adulthood were explored as potential pathways. The results showed that adolescent depression was associated with adult marginalization outcomes, but the strength of association varied across depressed subgroups. Adolescents with persistent depressive disorder had higher odds of all outcomes, including the composite marginalization measure (adjusted OR = 2.0, 95% CI = 1.4-2.7, p < 0.001), and this was partially (31%) mediated by subsequent depressive episodes in early adulthood. Exploratory moderation analysis revealed that entry into tertiary education mitigated the association with later marginalization, but only for adolescents with episodic major depression. In conclusion, the risk for future labor market marginalization is elevated among depressed adolescents, particularly those presenting with persistent depressive disorder. Targeted interventions seem crucial to mitigate the long-lasting impact of early-onset depression.

- Neuroticism is not only associated with affective disorders but also with certain somatic health problems. However, studies assessing whether neuroticism is associated with adverse obstetric or neonatal outcomes are scarce. This observational study comprises first-time mothers (n = 1969) with singleton pregnancies from several cohorts based in Uppsala, Sweden. To assess neuroticism-related personality, the Swedish universities Scales of Personality was used. Swedish national health registers were used to extract outcomes and confounders. In logistic regression models, odds ratios (ORs) with 95% confidence intervals (Cis) were calculated for the outcomes by an increase of 63 units of neuroticism (equalling the interquartile range). Analyses were adjusted for maternal age, educational level, height, body mass index, year of delivery, smoking during pregnancy, involuntary childlessness, and psychiatric morbidity. Main outcomes were mode of delivery, gestational diabetes mellitus, gestational hypertension, preeclampsia, induction of delivery, prolonged delivery, severe lacerations, placental retention, postpartum haemorrhage, premature birth, infant born small or large for gestational age, and Apgar score. Neuroticism was not independently associated with adverse obstetric or neonatal outcomes besides gestational diabetes. For future studies, models examining sub-components of neuroticism or pregnancy-specific anxiety are encouraged.

- IntroductionElevated neuroticism is associated with higher health care utilization in the general population. This study aimed to investigate the association between neuroticism and the use of publicly financed antenatal care in obstetric low‐risk women, taking predisposing and need factors for health care utilization into consideration.Material and methodsParticipants comprised 1052 obstetric low‐risk women (no chronic diseases or adverse pregnancy conditions) included in several obstetrics/gynecology studies in Uppsala, Sweden. Neuroticism was self‐rated on the Swedish universities Scales of Personality. Medical records of their first subsequent pregnancy were scanned for antenatal care use. Associations between antenatal care use and neuroticism were analyzed with logistic regression (binary outcomes) or negative binomial regression (count outcomes) comparing the 75th and 25th neuroticism percentiles. Depending on the Akaike information criterion the exposure was modeled as either linear or with restricted cubic splines. Analyses were adjusted for predisposing (sociodemographic and parity) and need factors (body mass index and psychiatric morbidity).ResultsAfter adjustment, women with higher neuroticism had more fetal ultrasounds (incidence rate ratio = 1.09, 95% confidence interval (CI) 1.02‐1.16), more emergency visits to an obstetrician/gynecologist (incidence rate ratio = 1.22, 95% CI 1.03‐1.45) and were more likely to visit a fear‐of‐childbirth clinic (odds ratio = 2.71, 95% CI 1.71‐4.29). Moreover, they more often consulted midwives in specialized antenatal care facilities (significant J‐shaped association).ConclusionsNeuroticism was associated with higher utilization of publicly financed antenatal care in obstetric low‐risk women, even after adjusting for predisposing and need factors. Future studies should address the benefits of interventions as a complement to routine antenatal care programs to reduce subclinical anxiety.

- Objectives: (i) To evaluate the reliability and factor structure of the Attachment Style Questionnaire – Short Form (ASQ-SF) for use in pregnant women and (ii) to compare the reliability and factor structure of the short- and full version-ASQ among pregnant women. Background: Adult attachment insecurity is currently included as a major risk factor in studies of perinatal health. None of the self-report measures with a Swedish translation have been psychometrically evaluated in a pregnant cohort.Methods: A population-based cohort of 1631 pregnant women answered the ASQ in late pregnancy. Internal consistency (item- subscale correlations, Cronbach’s α, and α if item deleted) was evaluated for the seven available subscales. Con rmatory factor analysis (CFA) was run to examine the factor structure of the short form compared with the full-version. Test–retest correlations were assessed in a subgroup (n = 48).Results: All mean item-subscale correlations for the ASQ-SF were > 0.30. Cronbach’s α’s for ASQ-SF dimensions were as follows: Avoidance (0.87); Anxiety (0.89); Discomfort with Closeness (0.85); Relationships as Secondary (0.54); Con dence (0.83); Need for Approval (0.76); and Preoccupation with Relationships (0.77). No item removal substantively increased subscale α’s. The CFA demonstrated better model t for the ASQ-SF than for the full-version ASQ, while other reliability measures were similar. Test–retest correlations ranged from 0.65 to 0.84.Conclusion: The ASQ-SF showed similar psychometric properties in pregnant women as in the general population and had good reliability, but the optimal factor structure needs to be studied further. Results support the usage of the ASQ-SF in pregnant cohorts.

- BACKGROUND: Maternal perinatal depression is a public health problem affecting mothers and children worldwide. This study aimed to increase the knowledge regarding the impact of timing of maternal depression on child behavioral difficulties at 18 months, taking into consideration child gender and maternal bonding.METHODS: Data from a Swedish population-based longitudinal mother-infant study (n = 1,093) were used for linear regression modeling. Associations between antenatal depression, postpartum depression, persistent depression and child behavioral problems were assessed.RESULTS: Maternal antenatal and persistent depression were associated with higher Child Behavior Checklist scores. Girls were affected to a greater degree. Postpartum bonding mediated most of the negative effects of postpartum and persistent depression on child behavior; not the effects of antenatal depression, however.LIMITATIONS: Child behavioral problems were reported by the mother. Information regarding paternal depressive symptoms was lacking.CONCLUSION: Different onset and timing of maternal depression showed distinct associations with child behavioral problems. The effects of antenatal depression were not mediated by maternal bonding, indicating underlying mechanisms possibly related to fetal programming. Screening of depressive symptoms even during pregnancy would be important in routine care in order to early identify and treat depression.
