How do persons with intellectual disability manage in the open labour markets? A follow-up of the Northern Finland 1966 Birth Cohort.

Nevin et al. (2005) followed adults with intellectual disability from a 1966 Finnish birth cohort. They looked at who worked, who stayed on disability pension, and who needed hospital care.

The team used government records to track jobs, pay, and health visits for the whole group. No new treatment was tested; it was a pure follow-up study.

Most adults with ID were on full disability pension. The few who worked had short, low-paid jobs with many lay-offs.

They also entered hospital more often than same-age peers without ID. Even mild ID led to poor work and health outcomes.

McQuaid et al. (2024) later showed the same risk pattern during COVID-19. Privately insured US adults with ID had 1.4 times the hospital odds and 2.7 times the death odds. The 2005 job gap and the 2024 virus data both say the same thing: adults with ID stay sicker.

Lemons et al. (2015) found that low IQ alone does not drive early death; lack of schooling explains most of the risk. This looks like a clash with Nevin et al. (2005), but the studies measured different things. A et al. counted jobs and hospital days; J et al. counted death certificates. School support may save lives even when jobs are still scarce.

Greenlee et al. (2024) now call for better data tags for people with IDD. Their paper folds the 2005 cohort into a wider plea: without good tracking, we will keep seeing the same poor work and health results.

For BCBAs, the message is clear: teaching vocational and daily-living skills is not enough if the client leaves school with no support network. Pair your skill programs with real work placements, medical care coordination, and long-term follow-up. One quick step you can take this week: add a brief job-health check-in to your monthly parent meeting. Ask if the adult client has seen a doctor, missed work, or lost a job. Early flags now can prevent hospital days later.
