The longitudinal association of combined regulatory problems in infancy and mental health outcome in early childhood: a systematic review.

Co-occurring regulatory problems in infancy, RPs, including excessive crying, feeding-eating and sleeping, have been found associated with mental health problems in school ages. Still, an overview is needed on trajectories of co-occurring or combined RPs, and mental health problems in early childhood. The aim of this review is to systematically review the literature on longitudinal community-based studies of combined RPs measuring mental health outcomes in early childhood.

Trajectories of dysregulation in preschool age.

Dysregulation of emotions, behaviour and attention is involved in several areas of childhood psychopathology, but knowledge about early developmental trajectories remains scarce. This study aims to explore continuity and associations of dysregulation in preschool age. Dysregulation was measured at age 2½ years and again at 5 years in a community-based birth cohort of 1099 children using the Child Behavior Checklist, preschool version (CBCL1½-5), answered by mothers.

Parental mental illness, attendance at preventive child healthcare and dental caries in the offspring: a nation-wide population-based cohort study.

Purpose: Severe mental illness (SMI) may interfere with parental caregiving practices and offspring development. Adhering to preventive well-child visits and maintaining good oral hygiene during early childhood requires parental involvement. Whether these activities are affected by parental SMI is unclear.

Disturbed sleep and activity in toddlers with early signs of attention deficit hyperactivity disorder (ADHD).

This study investigated whether early signs of attention deficit hyperactivity disorder (ADHD) in toddlers aged 2-3 years are associated with disturbed sleep and activity levels. Participants were recruited from the Odense Child Cohort, and children scoring above the 93 percentile on the ADHD scale of the Child Behaviour Checklist 1½-5 were categorised as cases and compared with age- and gender-matched normal-scoring controls. Daytime and nocturnal activity for 24 children with ADHD traits (cases) and 25 healthy controls was assessed through 7 days of actigraphy, and parents completed the Children's Sleep Habits Questionnaire (CSHQ) and the ADHD Rating Scale IV Preschool Version (ADHD-RS).
