Neuromotor Development and Motor Related Health Care in Children with a High Risk Neonatal Period

The overall aim of the study is to evaluate the prevalence of motor- and neurological disorders (cerebral pares and other less severe motor disorders) in Swedish infants with a high-risk neonatal period and to elucidate whether these children receive motor related health care (MRHC) at 2 and or 5,5 years of age.

Specific aims: 1. To evaluate the prevalence of cerebral pares (CP) and other motor impairments in Swedish infants with a high-risk neonatal period (total group and sub-groups), followed up at age 2 and or 5,5 years. 2. To study how retinopathy of prematurity (ROP) affects the risk for later gross and fine motor impairments in children with a high-risk neonatal period, with specific reference to children born extremely preterm. 3. To study the number of children, with a high-risk neonatal period having access to MRHC (defined as having at least one visit over the previous year to a physiotherapist and/or an occupational therapist). * To evaluate possible associations between receiving MRHC and maternal-, pregnancy- and neonatal factors. * To study the association between receiving MRHC and cognition, motor function, behavior, quality of life and autism spectrum disorders (ASD) at age 2 and 5,5 years. 4. To study if there are regional differences in Sweden in follow-up of CP and less severe motor disorders at the age of 2 and 5,5 years. 5. To assess the completeness and agreement of some developmental and motor disorders, neurosensory impairments and chronical diseases in the Swedish Neonatal Quality Register (SNQ) with the Swedish National Patient Register (NPR) and The Cerebral Palsy Follow-Up Program (CPUP).
