  • School performance and hospital admission due to unipolar depression : a three-generational study of social causation and social selection
  • 2012
  • Ingår i: Social Psychiatry and Psychiatric Epidemiology. - 0933-7954 .- 1433-9285. ; 47:10, s. 1695-1706
  • Tidskriftsartikel (refereegranskat)abstract
    • PurposeBoth "social causation" and "social selection" offer plausible explanations for an association between education and mental health. We aimed to explore these processes in unipolar depression, with a specific focus on school performance and family tradition of education.MethodGrandchildren (N = 28,089, 49% female, aged 13-47 years in 2002) of a cohort born in Uppsala, Sweden, in 1915-1929 were studied in national registers. We obtained data on final grade point average (GPA) in compulsory school, hospitalizations for unipolar depression, grandparental/parental education and other parental social characteristics. Hospitalization in adolescence and adulthood were studied separately, as were hospitalization for depression with or without a lifetime externalizing disorder.ResultsLow compulsory school GPA (1-2 SD or > 2 SD below average vs. average GPA) was associated with increased rate of adolescent hospitalization for unipolar depression, both with externalizing comorbidity [hazard ratio (HR) point estimates of 66-80] and without (HR point estimates of 4-6). By contrast, low GPA was only associated with first-time hospitalization in adulthood for the subgroup with externalizing comorbidity (HR point estimates of 4-6). These associations were largely independent of family education and social characteristics. Overall, low parental/grandparental education was not related to increased rates of hospitalization.ConclusionThe association between school performance and hospitalization for depression depended on adolescent hospitalization or externalizing comorbidity, suggesting that disorders with an early onset are decisive. Contrary to the social patterning of many health outcomes, low grandparental/parental education did not appear to increase the rate of hospitalization for unipolar depression in the offspring.

  • Subsequent higher education after adolescent depression : A 15-year follow-up register study
  • 2010
  • Ingår i: European psychiatry. - 0924-9338 .- 1778-3585. ; 25:7, s. 396-401
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Adolescent depression has been shown to have a range of adverse outcomes. We used longitudinal data to investigate subsequent higher education in former depressed adolescents. Method: A Swedish population-based investigation of depression in 16-17-year-olds was followed up in national registers 15 years later. Adolescents with depression (n=361, 78% females) were compared to a group of non-depressed peers of the same age (n=248, 77% females). The main outcome was graduation from higher education by age 30. Results: The adolescent with depression were less likely than their non-depressed peers to have graduated from higher education by age 30, both regarding females (27.7% vs. 36.4%, p<05) and males (12.7% vs. 28.6%, p<05). After adjustment for early school performance, socioeconomic status and maternal education, the decreased likelihood of subsequent graduation from higher education remained for depressed males (OR, 0.27; 95% CI, 0.08-0.93) but not for depressed females (OR, 0.93; 95% CI, 0.58-1.49). Conclusion: Contrary to what previous research has suggested, adolescent depression and its consequences might be particularly destructive to subsequent higher education in males.

  • Adolescent depression, early psychiatric comorbidities, and adulthood welfare burden : a 25-year longitudinal cohort study
  • 2021
  • Ingår i: Social Psychiatry and Psychiatric Epidemiology. - : Springer. - 0933-7954 .- 1433-9285. ; 56:11, s. 1993-2004
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Uppsala Longitudinal Adolescent Depression Study (ULADS)
  • 2019
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055 .- 2044-6055. ; 9:3
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Depressive disorders in adolescence, recurrence in early adulthood, and healthcare usage in mid-adulthood : A longitudinal cost-of-illness study
  • 2019
  • Ingår i: Journal of Affective Disorders. - : ELSEVIER. - 0165-0327 .- 1573-2517. ; 258, s. 33-41
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Depression in adolescence is associated with increased healthcare consumption in adulthood, but prior research has not recognized the heterogeneity of depressive disorders. This paper investigated the additional healthcare usage and related costs in mid-adulthood for individuals with adolescent depression, and examined the mediating role of subsequent depression in early adulthood.Methods: This study was based on the Uppsala Longitudinal Adolescent Depression Study, initiated in Sweden in the early 1990s. Depressive disorders were assessed in adolescence (age 16-17) and early adulthood (age 19-30). Healthcare usage and related costs in mid-adulthood (age 31-40) were estimated using nationwide population-based registries. Participants with specific subtypes of adolescent depression (n = 306) were compared with matched non-depressed peers (n = 213).Results: Women with persistent depressive disorder (PDD) in adolescence utilized significantly more healthcare resources in mid-adulthood. The association was not limited to psychiatric care, and remained after adjustment for individual and parental characteristics. The total additional annual cost for a single age group of females with a history of PDD at a population level was estimated at 3.10 million USD. Depression recurrence in early adulthood mediated the added costs for psychiatric care, but not for somatic care.Limitations: Primary health care data were not available, presumably resulting in an underestimation of the true healthcare consumption. Estimates for males had limited precision due to a relatively small male proportion.Conclusions: On a population level, the additional healthcare costs incurred in mid-adulthood in females with a history of adolescent PDD are considerable. Early treatment and prevention should be prioritized.

  • 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
  • Ingår i: BMC Psychiatry. - 1471-244X .- 1471-244X. ; 12, s. 90-
  • Tidskriftsartikel (refereegranskat)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.

  • Somatic symptoms as a marker for severity in adolescent depression
  • 2010
  • Ingår i: Acta Paediatrica. - 0803-5253 .- 1651-2227. ; 99:11, s. 1724-1730

    • Aim: This study aims to investigate the prevalence of somatic symptoms in depressed adolescents and in their healthy peers. A second aim is to investigate the correlation, in the depressed adolescents, between the number of somatic symptoms and severe concurrent symptoms, signs and life events. Methods: The total population of 16-17 year olds - in the city of Uppsala - was screened for depression and then interviewed using a structured interview questionnaire. Depressed subjects and matched controls were identified. A total of 177 pairs were used for pair-wise analyses of somatic symptoms. Severe symptoms, signs and life events were selected for analysing their relation to depression with somatic symptoms. Results: The adolescents with depressive disorders experienced considerably more somatic symptoms than their healthy controls. The duration and depth of the depression correlated with the number of somatic symptoms. There was a strong correlation between depression with many somatic symptoms and suicidal plans/thoughts, suicidal attempts, disruptive behaviour, as well as multiple stressful relationships. Conclusion: This study demonstrates that somatic symptoms are common in adolescent depression. Multiple somatic symptoms within depression imply a higher severity in terms of duration, depth and psychiatric comorbidity. The strong correlation with suicidal plans, suicidal attempts and disruptive behaviour is concerning.

  • 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
  • Ingår i: World Journal of Biological Psychiatry. - : Informa Healthcare. - 1562-2975 .- 1814-1412. ; 11:1, s. 71-75
  • Tidskriftsartikel (refereegranskat)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.

  • Intimate relationships and childbearing after adolescent depression : a population-based 15 year follow-up study
  • 2011
  • Ingår i: Social Psychiatry and Psychiatric Epidemiology. - 0933-7954 .- 1433-9285. ; 46:8, s. 711-721
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Adolescent depression is associated with a range of interpersonal adversities. We hypothesized that depressed adolescents are at subsequent increased risk of problems related to intimate relationships and childbearing in adulthood, and used longitudinal data to examine this.Method: A population-based investigation of depression in 16 to 17 year olds was followed up after 15 years, at around the age of 30 years. Comparisons were made between adolescents with depression (n = 361, 78% females) and non-depressed peers (n = 248, 77% females). Data from both national registers and personal interviews were used.Results: At follow-up, the former depressed and non-depressed adolescents had become parents to a similar extent. The former depressed females were more likely than the non-depressed females to report abortion, miscarriage, intimate partner violence and sexually transmitted disease. They also reported a higher number of intimate relationships and were more likely to have divorced and to be registered as single mothers. Depressed females with a comorbid disruptive disorder had a particularly poor outcome. In the depressed females without a disruptive disorder, only those who subsequently had recurrent depressions in adulthood were at increased risk of poor outcome. There was no indication that the formerly depressed males were at increased risk of subsequent problems related to intimate relationships.Conclusion: Females with adolescent depression subsequently have problems related to intimate relationships and childbearing. Disruptive disorders and recurrence of depression appear to be instrumental in this association. Attention should be given to intimate relationship problems and sexual and reproductive health issues in young women with depression.

  • Mental health outcome of long-term and episodic adolescent depression : 15-year follow-up of a community  sample
  • 2011
  • Ingår i: Journal of Affective Disorders. - 0165-0327 .- 1573-2517. ; 130:3, s. 395-404
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Recent studies have highlighted the unfavourable natural course of chronic/long-term depression. We investigated the adult mental health outcome of adolescent depression, with specific focus on long-term and episodic adolescent major depression (MD). METHODS: A community sample of depressed adolescents and non-depressed peers was followed-up with a structured diagnostic interview after 15years. The participants (n=382) were divided into five groups depending on their status in adolescence: no depression (n=155); long-term MD (n=91); episodic MD (n=63); dysthymia (n=33); and subthreshold symptoms (n=40). Outcomes (age 19-31) included mood disorders, other mental disorders, suicidality, and treatment for mental disorders. RESULTS: The long-term group overall had a poorer outcome than the non-depressed group, with the episodic group in an intermediate position. The outcome of the dysthymic group was similar to that of the long-term group, while the subsyndromal group did not differ markedly from the non-depressed group. The long-term group was more likely than the episodic group to report adult anxiety disorders, multiple mental disorders, suicide attempts, and treatment; they also seemed to develop more persistent adult depressions, with a higher number of recurrent episodes and longer duration of antidepressant treatment. Even after adjustment for adolescent factors of clinical and etiological importance, the long-term group had a markedly less favourable outcome than the episodic group. LIMITATION: The participation rate at follow-up was 64.6%. CONCLUSION: Longstanding depression in adolescence is a powerful predictor of continued mental health problems in adulthood. It is now important to evaluate if early interventions can alter this severe course.
