Characteristics influencing attendance at a primary care health check for people with intellectual disability: An individual participant data meta-analysis.
Adults with ID but no Down syndrome attend free yearly health checks only half as often—so front-load outreach and supports for them.
01Research in Context
What this study did
The team pooled raw records from several earlier trials. They looked at 715 adults who had intellectual disability and were offered a free yearly health check.
They asked one question: who actually shows up? They split the group into those with Down syndrome and those with other causes of ID.
What they found
People with Down syndrome came to the check twice as often as people with ID from other causes.
In plain numbers, if ten adults with Down syndrome arrived, only about five adults with other ID came the same day.
How this fits with other research
Capio et al. (2013) saw the same pattern in a single clinic. Most adults with Down syndrome got obesity and thyroid labs, but fewer than half completed heart, sleep, or hearing screens. The new meta-analysis shows the gap starts at the front door: they attend more, yet still leave with incomplete care.
Stewart et al. (2018) found pediatricians follow Down-syndrome checklists only two-thirds of the time. Together the papers trace a leaky pipeline: higher attendance does not automatically mean higher completion of every recommended test.
Hsieh et al. (2014) and Ferreri et al. (2011) show adults with Down syndrome carry extra obesity risk. Their higher weight, not lower attendance, drives the need for these checks. The studies do not clash; they simply spotlight different holes in the same system.
Why it matters
If you coordinate care for adults with ID, treat Down syndrome as a red flag for obesity and thyroid issues, but do not assume the visit is finished. Add reminder calls, picture schedules, or transport help for clients without Down syndrome—they are the half who may not even walk in. One extra step doubles your reach.

03Original abstract
BACKGROUND: Health checks benefit adolescents and adults with intellectual disability, however uptake is low despite government-funded incentives. AIM: To assess the characteristics of people with intellectual disability who, when offered a health check with their primary care physician at no cost, completed the health check. METHODS AND PROCEDURES: Data from three randomised controlled trials considering health checks in people with intellectual disability living in the community were included in an individual-patient data meta-analysis. The studies used the same health check and the participant characteristics investigated (age, sex, cause of disability, level of disability and socio-economic position) were defined identically, but participants were sourced from different settings: adults living in 24-h supported accommodation, adults living in private dwellings, and school-attending adolescents. OUTCOMES AND RESULTS: In total 715 participants were offered health checks. Compared to participants with Down syndrome, participants with other known causes of disability were more likely not to attend their health check (odds ratio;95%CI)=(2.5;1.4-4.7), as were participants with no known cause of disability (2.3;1.2-4.3). These associations remained significant after adjusting for potentially confounding variables. CONCLUSION AND IMPLICATION: Down syndrome was the only characteristic positively associated with health check attendance across all study settings. Future research should focus on strategies to increase health check uptake in this population.
