Cohort profile: The 'Children's Health in Care in Scotland' (CHiCS) study-a longitudinal dataset to compare health outcomes for care experienced children and general population children.

Purpose: The Children's Health in Care in Scotland Cohorts were set up to provide first population-wide evidence on the health outcomes of care experienced children (CEC) compared with children in the general population (CGP). To date, there are no data on how objective health outcomes, mortality and pregnancies for CEC are different from CGP in Scotland.

Participants: The CEC cohort includes school-aged children who were on the 2009/2010 Scottish Government's Children Looked After Statistics (CLAS) return and on the 2009 Pupil Census (PC).

Age at identification, prevalence and general health of children with autism: observational study of a whole country population.

Objectives: Reported childhood prevalence of autism varies considerably between studies and over time, and general health status has been little investigated. We aimed to investigate contemporary prevalence of reported autism by age, and general health status of children/young people with and without autism.

Design: Secondary analysis of Scotland's Census, 2011 data.

Prevalence of sensory impairments, physical and intellectual disabilities, and mental health in children and young people with self/proxy-reported autism: Observational study of a whole country population.

This study investigated the comorbid conditions in a whole country population of children/young people aged 0-24 years with and without autism. Data were drawn from Scotland's Census 2011. We calculated the percentage with autism, their extent of comorbid conditions, odds ratio (with 95% confidence intervals) of autism predicting comorbidities, adjusted for age and gender, and odds ratio for age and gender predicting comorbidities within the cohort with autism.

Prevalence of long-term health conditions in adults with autism: observational study of a whole country population.

Objectives: To investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.

Design: Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study.

Prevalence and general health status of people with intellectual disabilities in Scotland: a total population study.

Background: Prevalence of intellectual disabilities varies considerably between studies. People with intellectual disabilities experience health inequalities, but most studies comprise small or incomplete populations. We investigated in a whole country population the (1) prevalence of intellectual disabilities and (2) general health status compared with the general population.

Prevalence of mental health conditions and relationship with general health in a whole-country population of people with intellectual disabilities compared with the general population.

Background: There are no previous whole-country studies on mental health and relationships with general health in intellectual disability populations; study results vary.

Aims: To determine the prevalence of mental health conditions and relationships with general health in a total population with and without intellectual disabilities.

Method: Ninety-four per cent completed Scotland's Census 2011.
