Prevalence of attention-deficit/hyperactivity disorder and autism in 12-year-old children: A population-based cohort.

Aim: To investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in a population-based birth cohort and correlate the findings with prenatal and perinatal factors. We hypothesized that children born preterm, having experienced preeclampsia or maternal overweight, would have an increased risk of ADHD or ASD.

Method: A Swedish cohort of 2666 children (1350 males, 1316 females) has been followed from birth with parental and perinatal data.

Data-driven, client-centric applied behavior analysis treatment-dose optimization improves functional outcomes.

Background: With increasing numbers of individuals diagnosed with autism spectrum disorder (ASD) and with affirmation of applied behavior analysis (ABA) as an evidence-based standard of care for ASD, there has been a proliferation of agencies offering ABA services over the last several decades. Disagreement exists among ABA providers and health plans that reimburse those providers on the optimal number of hours of ABA services that should be reimbursed. This study aims to understand whether children who receive more hours of ABA therapy achieve better outcomes and to evaluate the impact of the COVID-19-induced shift to telehealth clinical supervision on outcomes.

Half of the children with overweight or obesity and attention-deficit/hyperactivity disorder reach normal weight with stimulants.

Aim: Treatment of childhood obesity is often insufficient and may be aggravated by high co-occurrence of attention-deficit/hyperactivity disorder (ADHD). We aimed to investigate whether children with overweight or obesity normalised in weight when receiving stimulant treatment for ADHD.

Methods: Growth data of 118 children were obtained from medical records at outpatient paediatric and children's psychiatric services in the Gothenburg area, Sweden.
