In Part Two of this article on sleep issues and ADHD I am going to break the very accurate Swedish Statistics on the subject. In Part One I looked the figures for sleep disturbances as one group.
Now I will break the figures down into 8 different categories and how uncommon they are compared top non-ADHD people.
Here are the figures from the highest to the lowest.
The Swedish team that undertook this study concluded their work saying this:
“Our findings also suggest that greater clinical attention should be directed towards addressing sleep problems in individuals with ADHD. This entails implementing proactive measures through sleep education programmes and providing both pharmacological and non-pharmacological approaches such as cognitive behavioural therapy and parental sleep training.”
The Method Used by the Swedes
- Sweden has a single-payer health insurance system and a series of national population registers that track virtually its entire population.
- Using the Swedish Total Population Register, a local research team created a cohort of all 6,470,658 persons born between 1945 and 2008.
- They linked this to the Swedish National Patient Register, which includes inpatient hospitalizations from 1975 to 2013, and outpatient specialist diagnoses from 2001 to 2013, to identify diagnoses of sleep disorders.
- They also linked to the Prescribed Drug Register, covering 2005 to 2013, to identify prescriptions for sleep medications.
