Morbidity and hospitalizations of adults with Down syndrome.
Adults with Down syndrome are hospitalized twice as often and stay longer—screen proactively for respiratory infections and hypothyroidism to reduce admissions.
01Research in Context
What this study did
Tenenbaum et al. (2012) tracked every hospital stay for adults with Down syndrome in one state. They counted how often people were admitted and how long they stayed. They also listed the main medical reasons for each visit.
What they found
Adults with Down syndrome went into the hospital twice as often as other adults. Each stay was also longer. Breathing infections and low thyroid were the top causes.
How this fits with other research
Fullana et al. (2007) saw the same breathing problem in babies. Half of kids with Down syndrome were hospitalized before age three, mostly for chest infections. The trouble starts early and continues into adult life.
Hickey et al. (2025) recently confirmed the pattern in over 2,000 children. Eight in ten needed intensive care at birth, and more than half later had sleep apnea or heart surgery. These early issues set the stage for the adult admissions Ariel reports.
Ghaziuddin et al. (1996) pooled older papers and already flagged low thyroid as a major risk. Ariel’s inpatient numbers now show how that untreated thyroid quietly fills hospital beds.
Why it matters
If you support adults with Down syndrome, schedule yearly thyroid blood tests and lung checks. Catch a cold early, treat it fast, and you may prevent a long hospital stay. Share the checklist with families and primary doctors so everyone watches the same red flags.

03Original abstract
Over the last decade a significant increase in the life expectancy of people with Down syndrome (DS) has been observed, which has caused a higher incidence of morbidity as they age. However, there is a lack of literature regarding morbidity and hospitalization of adults with DS. Analysis of 297 hospitalizations of 120 adults with DS aged 18-73 years hospitalized at Hadassah Medical Centers during the years 1988-2007 compared with data of the general population, hospitalized at the same period. At the age range 18-66 years, mean number of hospitalizations was significantly higher than the general population (P = 0.000001) with hospitalization also significantly longer (P = 0.0009). Exceptionally long hospitalizations were seen at the departments of internal medicine, dermatology and intensive care units. There was no significant difference in mortality between DS and the general population (P = 0.221). More than a fourth of the hospitalizations were caused by infectious diseases, mostly respiratory infections. Hypothyroidism was more prevalent compared with the estimated number reported by the literature (30.8% vs. 15%). Convulsive disorder was prevalent as well (15.8%). However, the prevalence of congenital heart disease, dementia, osteoporosis and obesity was found less than expected. Adults with DS are hospitalized more than the general population and for longer duration. The results of this study emphasize the need for preventive community-based medicine, awareness of co-morbidities and possible deterioration and to prepare the medical staff for a complex course of illness, expecting longer hospitalizations, arising from the complexity of this population.
