Objective: The purpose of this study was to examine the associations of ADHD and ODD symptoms in adolescence with occupational outcomes and incomes in adulthood within the Northern Finland Birth Cohort 1986 (NFBC1986). Method: ADHD symptoms were evaluated at ages 15 to 16 years using the Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) scale. ODD symptoms were assessed using a 7-point scale, like the SWAN assessment. Results: Symptoms of ADHD and ADHD + ODD were associated with elevated rates of unemployment, increased sick days, and lower annual incomes compared to controls for both sexes. Symptoms of ODD were associated with higher unemployment and more sick days for males, although these associations did not reach statistical significance in their association with annual incomes. Conclusion: Symptoms of ADHD were associated with adverse occupational outcomes and lower incomes. Furthermore, symptoms of ODD were associated with occupational outcomes but not with incomes.

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. 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. 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. Our findings reveal unique comorbidity-related temperament factors, which may have implications for adaptive and personalizing intervention efforts. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The aim of the study was to examine the possible relation between adolescent ADHD and high BMI, studying also eating behavior and physical activity. The data were collected from the Northern Finland Birth Cohort 1986. The follow-up at the age of 16 consisted of a self-assessment form and clinical examination where height and weight were measured and questionnaires on physical activity and eating habits was completed. ADHD diagnosis was based on a diagnostic interview with adolescents and parents according to DSM-IV-TR criteria. The participants were divided into the following study groups: individuals with adolescent ADHD (n = 90), those with only childhood ADHD (n = 40), and community controls (n = 269). Results showed no significant differences in BMI, but adolescents with ADHD seemed to have unhealthier eating habits than controls; they ate less often vegetables and breakfast, devoured more often, and consumed more fast food, soft drinks, sweets, and potato crisps daily. Individuals with adolescent ADHD reported light exercise more often but strenuous exercise more seldom than controls. Those with only childhood ADHD did not significantly differ from community controls regarding health behaviors. There was no relation between ADHD and high BMI but adolescents with ADHD had unhealthier eating habits than those without ADHD. It is conceivable that unhealthy eating behaviors in adolescence might be a risk factor for the development of later overweight; however, the longitudinal associations between ADHD, unhealthy eating behaviors and overweight have not been considered in the present study and remain to be examined further.

Diagnosis of attention deficit hyperactive disorder (ADHD) has been associated with increased risk of mortality in large register samples. However, there is less known about the association between symptoms of ADHD in adolescents and risk of mortality in general population samples. The Northern Finland Birth Cohort 1986 (n = 9432 at recruitment in early pregnancy) linked to nationwide register data for deaths was utilized to study the association between parent-rated ADHD symptoms assessed using Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) questionnaire and mortality until age 33 years. Cox-regression analysis with hazard ratios (HRs) and 95% confidence intervals (CIs) was used to study the association between SWAN inattentive, hyperactive, and combined symptom scores and risk of death. Sixty-three (0.9%) of the 6685 participants died during the follow-up. Higher SWAN inattentive (crude HR = 2.30, 95% CI 1.46–3.63), SWAN hyperactive (crude HR = 2.43, 95% CI 1.29–4.56), and SWAN combined (crude HR = 2.69, 95% CI 1.57–4.61) scores were associated with increased risk of death. After adjustments for sex, family structure, and lifetime parental psychiatric disorder, these associations persisted. Further adjustment for frequent alcohol intoxication, cannabis, and other substance use in adolescence attenuated these to below statistical significance. These results extend previous findings on the risk of mortality in adolescents who have symptoms of ADHD. Further research with larger samples are needed to determine whether the association between ADHD symptoms and mortality is independent of adolescent substance use. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the military performance of men with adolescent attention-deficit/hyperactivity disorder (ADHD) and men with childhood ADHD (in remission during adolescence) as compared with controls without ADHD. The study employs the general population-based Northern Finland Birth Cohort 1986 (NFBC1986) together with data received from the Finnish Defence Forces (FDF). A total of 38 men with childhood ADHD and 67 with adolescent ADHD were compared with 160 controls. The men with adolescent ADHD were more often deemed unfit for military service, had more military health care visits, more often committed at least one offence during service, received poorer evaluations for team leadership skills and indulged in more alcohol consumption and smoking than the controls, while those with childhood ADHD did not differ from the controls in their military fitness, but received poorer evaluations for team leadership skills and smoked more than did the controls. The conscripts with adolescent ADHD performed worse on many military parameters, but the men with ADHD in remission did not seem to suffer from such negative effects on military performance. The childhood ADHD group in particular was nevertheless somewhat limited in size, which might have led to a Type II error. [ABSTRACT FROM AUTHOR]

Prior research has established a strong link between attention deficit hyperactivity disorder (ADHD) and criminal behaviour. Drawing on two key theories of life-course criminology — Moffitt’s (1993) dual taxonomy and Sampson and Laub’s (1993) age-graded theory of informal social control — the purpose of the present study was to examine the aetiology of this association. Consistent with Moffitt’s theory, we found the effect of ADHD on crime to be substantial and moderated by cognitive deficits (low verbal ability). Adolescent social bonds — variables derived from Sampson and Laub’s theory — did not mediate the interaction effect. However, in support of age-graded theory, we found that adolescent social marginalization contributes significantly to criminal behaviour independently of early childhood measures of criminal propensity.

An abstract of the article "ADOLESCENT ADHD AND FAMILY ENVIRONMENT - AN EPIDEMIOLOGICAL AND CLINICAL STUDY OF ADHD IN THE NORTHERN FINLAND 1986 BIRTH COHORT," by Tuula Hurtig is presented.

• Social cognition includes understanding others' emotions from facial expressions. • Adults with previous ADHD exhibit overactive face network properties. • Differences were found in brain regions linked to recognizing facial expressions. • Differences were found in brain regions linked to attention. The symptoms of ADHD tend to have continuity to adulthood even though the diagnostic criteria were no longer fulfilled. The aim of our study was to find out possible differences in BOLD signal in the face-processing network between adults with previous ADHD (pADHD, n = 23) and controls (n = 29) from the same birth cohort when viewing dynamic facial expressions. The brain imaging was performed using a General Electric Signa 1.5 Tesla HDX. Dynamic facial expression stimuli included happy and fearful expressions. The pADHD group demonstrated elevated activity in the left parietal area during fearful facial expression. The Network Based Statistics including multiple areas demonstrated higher functional connectivity in attention related network during visual exposure to happy faces in the pADHD group. Conclusions: We found differences in brain responses to facial emotional expressions in individuals with previous ADHD compared to control group in a number of brain regions including areas linked to processing of facial emotional expressions and attention. This might indicate that although these individuals no longer fulfill the ADHD diagnosis, they exhibit overactive network properties affecting facial processing. [ABSTRACT FROM AUTHOR]
