Association between Exposure of Young Children to Procedures Requiring General Anesthesia and Learning and Behavioral Outcomes in a Population-based Birth Cohort Open
Background Exposure of young animals to general anesthesia causes neurodegeneration and lasting behavioral abnormalities; whether these findings translate to children remains unclear. This study used a population-based birth cohort to test…
Clustering and Variable Selection in the Presence of Mixed Variable\n Types and Missing Data Open
We consider the problem of model-based clustering in the presence of many\ncorrelated, mixed continuous and discrete variables, some of which may have\nmissing values. Discrete variables are treated with a latent continuous\nvariable appro…

What can large population-based birth cohort study ask about past, present and future of children with disorders of development, learning and behaviour? Open
A large cohort consisting of all children born to mothers from community provides ‘natural’ selection into different exposures and is a powerful resource for epidemiological research. A large population-based birth cohort with detailed sys…
Academic Achievement in Adults with a History of Childhood Attention-Deficit/Hyperactivity Disorder: A Population-Based Prospective Study Open

Adults With Persistent ADHD: Gender and Psychiatric Comorbidities—A Population-Based Longitudinal Study Open
Objective: The aim of the study was to evaluate associations between ADHD and comorbid psychiatric disorders among adults from a population-based birth cohort. Method: Participants were recruited from all children born between 1976 and 198…
Explanatory Style in Patients with Rheumatoid Arthritis: An Unrecognized Predictor of Mortality Open
Objective. To determine whether pessimistic explanatory style altered the risk for and mortality of patients with rheumatoid arthritis (RA). Methods. The study included subjects from a population-based cohort with incident RA and a non-RA …
Mediating and Moderating Role of Depression, Conduct Disorder or Attention-Deficit/Hyperactivity Disorder in Developing Adolescent Substance Use Disorders: A Population-Based Study Open
For clinicians our results emphasize that depression (or CD/ODD) confers greater risk for SUD than ADHD alone. Early detection/treatment of SUD among adolescents with depression (or CD/ODD) is crucial regardless of ADHD.

Construction and Characterization of a Population-Based Cohort to Study the Association of Anesthesia Exposure with Neurodevelopmental Outcomes Open
Exposure to general anesthesia at an early age has been associated with adverse neurodevelopmental outcomes in both animal and human studies, but some of these studies employed anesthetic agents that are no longer in clinical use. In this …
Do pessimists report worse outcomes after total hip arthroplasty? Open
A pessimistic explanatory style was associated with moderate-severe activity limitation and a non-significant trend towards moderate-severe pain post-THA.
Adults with persistent ADHD: Gender and psychiatric comorbidities – a population-based longitudinal study Open
Objective To evaluate in adults the associations between persistent ADHD and comorbid psychiatric disorders and gender differences, among subjects from a population-based birth cohort. Method Subjects were recruited from a birth cohort of …
