We studied the association between participation in the longitudinal follow-up study and cardiometabolic disorders in two longitudinal studies which started prospectively in the antenatal period: the Northern Finland Cohort 1966 (NFBC1966) and the Northern Finland Birth Cohort 1986 (NFBC1986). Both birth cohorts have been followed up since birth with multiple follow-ups including questionnaires, and clinical examinations. The NFBC studies were compared to comparison cohorts of individuals who were born in the same area as the study cohorts, but in different years. The data for the comparison cohort were obtained from registers. The cumulative incidence rates of hospital-treated cardiometabolic disorders were calculated for study and comparison cohorts covering the age of 7–50 years in NFBC1966 and the age of 0–29 years in NFBC1986. Cardiometabolic-related causes of death were analysed in NFBC1966 and the comparison cohort from the age of 0–50 years. The analysed cardiometabolic disorders were diabetes mellitus, coronary artery disease, hyperlipidaemia, obesity, hypertension, and cerebrovascular disorders. The risk ratio (RR) with 95% confidence intervals (CI) was calculated by sex. In NFBC1966, no differences in cumulative incidences of cardiometabolic disorders or cardiometabolic-related deaths compared to the comparison cohort were found. Male members of NFBC1986 had decreased risk of obesity (RR: 0.45, 95% CI: 0.27–0.75) and any cardiometabolic disorders (RR: 0.75, 95% CI: 0.59–0.95) compared to the comparison cohort. The results suggest that participation in the NFBC1986 may have a weak positive health effect among men. Agreement to follow-up studies focusing on diet, substance use, and physical activity, may slightly decrease the incident risk of cardiometabolic disorders in the study population. Even mild interventions, such as follow-up studies in the prospective follow-up studies, might affect participants' behaviour and consequently the incidence of cardiometabolic disorders The fact that follow-up itself might affect the study population in terms of risk factors, has to be taken into account when estimating the representativeness of the followed population.

Parental death before adulthood has been shown to increase offspring's risk of poor health and adverse social consequences. In a sample of 422 subjects with parental death (334 (79.1%) due to natural causes), and 6172 matched controls, those with parental death were given a diagnosis of a psychiatric disorder up to 28 years of age earlier than their controls (10-year survival proportions: 88.6% vs. 93.1%, p = 0.001). Our findings indicate that psychosocial support must be provided as early as when a parent falls ill, especially with those illnesses that are the most common causes of death in the population.

Background: Disruptive behavioral disorders (DBD) and attention-deficit hyperactivity disorder (ADHD) are both characterized by certain patterns of misbehavior among adolescents. Aims: The aim of this study was to examine how the comorbidity of DBD and ADHD affects in misbehavior among adolescents. Methods: A total of 158 adolescents aged 16-18 years, from a subsample of the Northern Finland Birth Cohort 1986 (NFBC 1986), were interviewed with the Finnish translation of the semi-structured Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime (K-SADS-PL) in order to obtain DBD, including conduct disorder (CD) and oppositional defiant disorder (ODD), and ADHD diagnoses. The structure of the CD symptoms, obtained from the K-SADS-PL, was compared with the previously formed model about the development of the problematic behavior. The severity of the CD symptoms was compared with adolescents diagnosed with only DBD, only ADHD and with both DBD and ADHD. Also, the associations with other psychiatric disorders diagnosed at age 16 were evaluated. Results: The boys in the study sample were diagnosed with ADHD or with comorbid DBD and ADHD more often than girls. The severity of CD symptoms was statistically significantly associated with the comorbid DBD and ADHD group. The adolescents diagnosed with comorbid DBD and ADHD had an increased risk for anxiety disorders, depressive disorders and substance abuse disorders. Conclusions: The comorbidity of DBD and ADHD seems to indicate the severity of CD symptoms. Clinical implications: The comorbidity between DBD and ADHD should be considered in clinical practice because it could indicate more serious problematic behavior than pure disorders alone.

Background: Suicidal behaviour, i.e. suicidal ideation and suicidal acts, as well as self-harm behaviour, are relatively common among adolescents. Depression and/or female gender seem to be risk factors for suicidal behaviour. However, the role of attention deficit hyperactivity disorder (ADHD) in these behaviours is still unclear. Aim: To study the effect of ADHD on suicidal or self-harm behaviour in adolescents from a general population sample. Methods: The sample was derived from a population-based Northern Finland Birth Cohort 1986 ( n = 9432). Based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version (Kiddie-SADS-PL) interview performed in a subpopulation ( n = 457), the associations between suicidal behaviour and deliberate self-harm (DSH) and the diagnosis of ADHD were studied. Results: Compared with adolescents without ADHD ( n = 169), those with ADHD ( n = 104) had more suicidal ideation (57% vs. 28%, P < 0.001) and DSH (69% vs. 32%, P < 0.001). In binary logistic models, the effect of ADHD on suicidal ideation remained strong (OR = 6.1) after controlling for several other predictors. Other contributing factors in suicidal behaviour included female gender, childhood emotional and behavioural problems, concurrent depression and anxiety, and, specifically in DSH, behavioural disorder, substance abuse and strains in family relations. Discussion and clinical implications: ADHD is a risk factor for suicidal ideation and DSH. These findings in a general population sample speak for a need to target mental health interventions at children and adolescents with relevant symptoms of ADHD. [ABSTRACT FROM AUTHOR]

This study is one of very few that has investigated the neuropsychological functioning of both familial and clinical high risk subjects for psychosis. Participants (N = 164) were members of the Northern Finland 1986 Birth Cohort in the following four groups: familial risk for psychosis (n = 62), clinical risk for psychosis (n = 20), psychosis (n = 13), and control subjects (n = 69). The neurocognitive performance of these groups was compared across 19 cognitive variables. The two risk groups did not differ significantly from controls, but differed from the psychosis group in fine motor function. Neuropsychological impairments were not evident in a non-help-seeking high-risk sample. [ABSTRACT FROM AUTHOR]
