Neural connectivity biotypes: associations with internalizing problems throughout adolescence.

ABSTRACT:

Background

Neurophysiological patterns may distinguish which youth are at risk for the well-documented increase in internalizing symptoms during adolescence. Adolescents with internalizing problems exhibit altered resting-state functional connectivity (RSFC) of brain regions involved in socio-affective processing. Whether connectivity-based biotypes differentiate adolescents' levels of internalizing problems remains unknown.

Method

Sixty-eight adolescents (37 females) reported on their internalizing problems at ages 14, 16, and 18 years. A resting-state functional neuroimaging scan was collected at age 16. Time-series data of 15 internalizing-relevant brain regions were entered into the Subgroup-Group Iterative Multi-Model Estimation program to identify subgroups based on RSFC maps. Associations between internalizing problems and connectivity-based biotypes were tested with regression analyses.

Results

Two connectivity-based biotypes were found: a Diffusely-connected biotype (N = 46), with long-range fronto-parietal paths, and a Hyper-connected biotype (N = 22), with paths between subcortical and medial frontal areas (e.g. affective and default-mode network regions). Higher levels of past (age 14) internalizing problems predicted a greater likelihood of belonging to the Hyper-connected biotype at age 16. The Hyper-connected biotype showed higher levels of concurrent problems (age 16) and future (age 18) internalizing problems.

Conclusions

Differential patterns of RSFC among socio-affective brain regions were predicted by earlier internalizing problems and predicted future internalizing problems in adolescence. Measuring connectivity-based biotypes in adolescence may offer insight into which youth face an elevated risk for internalizing disorders during this critical developmental period.

Project description:ImportanceMental health problems in early life are associated with labor market marginalization, especially in youths with persistent internalizing and externalizing problems. However, previous research has not adjusted for familial (genetic and shared environmental) factors.ObjectiveTo examine associations of early-life internalizing and externalizing problems with adulthood unemployment and work disability, adjusting for familial factors.Design, setting, and participantsThis population-based prospective cohort study included Swedish twins who were born in 1985-1986 and surveyed at 4 consecutive waves across childhood and adolescence until 2005. Through linkage to nationwide registries, participants were followed up from 2006 to 2018. Data analyses were conducted between September 2022 and April 2023.ExposuresInternalizing and externalizing problems, assessed with the Child Behavior Checklist. Participants were differentiated regarding duration of internalizing and externalizing problems (persistent, episodic, and noncases).Main outcomes and measuresUnemployment (180 days or more of being unemployed) and work disability (60 days or more of being sickness absent or disability pensioned) during follow-up. Cox proportional hazards regression models were calculated to obtain cause-specific hazard ratios (HRs) with 95% CIs in the whole cohort and exposure-discordant twin pairs.ResultsOf 2845 participants, 1464 (51.5%) were female. Incident unemployment was experienced by 944 (33.2%) and incident work disability by 522 (18.3%) participants. Compared with noncases, persistent internalizing problems were associated with unemployment (HR, 1.56; 95% CI, 1.27-1.92) and work disability (HR, 2.32; 95% CI, 1.80-2.99). Similarly, compared with noncases, persistent externalizing problems were associated with unemployment (HR, 1.87; 95% CI, 1.55-2.26) and work disability (HR, 2.38; 95% CI, 1.87-3.03). Persistent cases had overall higher risks of adverse outcomes than episodic cases. After adjustment for familial factors, associations with unemployment were no longer statistically significant, whereas associations with work disability remained or were only slightly reduced.Conclusions and relevanceIn this cohort study of young Swedish twins, familial factors explained the associations between early-life persistent internalizing and externalizing problems and unemployment; such factors were comparatively less important for the association with work disability. This suggests nonshared environmental factors may be important for the risk of future work disability among young individuals with persistent internalizing and externalizing problems.

Project description:Importance:Although multiple cross-sectional and longitudinal studies have established that sleep problems and behavioral difficulties are associated in children, the directionality of this association and whether sleep problems are differentially associated with different types of childhood behavioral difficulties are unclear. Understanding these associations will inform the focus and timing of interventions. Objective:To determine whether longitudinal and reciprocal associations exist between child sleep problems and externalizing, internalizing, or both behavioral difficulties. Design, Setting, and Participants:Prospective cohort study using nationally representative data from the first 5 waves (2004, 2006, 2008, 2010, and 2012) of the kindergarten cohort (4983 children aged 4-5 years in 2004) collected for the Longitudinal Study of Australian Children. Associations were evaluated using cross-lagged structural equation model analyses performed from May 25, 2016, to September 20, 2017. Main Outcomes and Measures:Child sleep problems and internalizing and externalizing behavioral difficulties. Sleep problems were defined using parent-reported child sleep problem severity and specific difficulties (ie, difficulty getting to sleep at night, not happy sleeping alone, waking during the night, and restless sleep) on 4 or more nights of the week. Child behavioral difficulties were defined using the parent-reported Strengths and Difficulties Questionnaire for externalizing difficulties (conduct problems and hyperactivity/inattention subscales) and internalizing difficulties (emotional problems subscale). Results:The 4983 children enrolled in 2004 had a mean (SD) age of 4.7 (0.2) years and comprised a similar percentage of boys (2536 [50.9%]) and girls. In 2012, 3956 children (79.4%) aged 12 to 13 years were retained. Significant bidirectional associations were detected between sleep problems and externalizing difficulties during the elementary school transition period, with greater sleep problems associated with later externalizing behavior and vice versa (cross-lagged path coefficient, 0.04 [95% CI, 0.01-0.08] to 0.09 [95% CI, 0.06-0.13]). Although sleep was a significant driver of later internalizing difficulties (coefficient, 0.10 [95% CI, 0.07-0.14] to 0.16 [95% CI, 0.12-0.19]), the reverse association was not significant. In the final model that included all 3 constructs, the associations were attenuated but remained significant over time. Conclusions and Relevance:These results suggest that future studies should investigate whether implementing sleep problem intervention decreases the occurrence of both externalizing and internalizing difficulties. Interventions targeting externalizing, but not internalizing, difficulties may benefit childhood sleep.
