Heterogeneity in age at death for adults with developmental disability

Area of Science:

• Public Health
• Gerontology
• Disability Studies

Background:

• Mortality trends for adults with developmental disabilities are increasingly studied.
• Previous research has not differentiated age at death by specific disability types.
• Understanding heterogeneity in mortality is crucial for targeted interventions.

Purpose of the Study:

• To investigate variations in age at death among adults with different types of developmental disabilities.
• To determine if heterogeneity exists in mortality patterns across diverse developmental disabilities.
• To inform public health strategies by accounting for disability-specific mortality differences.

Main Methods:

• Analysis of U.S. Multiple Cause-of-Death Mortality files (2012-2016).
• Examination of mean age at death and age distributions for adults (18-126 years).
• Stratification of data by developmental disability type and biological sex.

Main Results:

• Adults with developmental disabilities had a lower mean age at death compared to those without.
• Significant variations in age at death were observed across different developmental disability types and sexes.
• Individuals with intellectual disability had the highest age at death, whereas those with cerebral palsy or rare developmental disabilities had the lowest.

Conclusions:

• Age at death research for adults with developmental disabilities must acknowledge heterogeneity among disability types.
• Failure to account for these differences can lead to inaccurate public health and preventive care guidance.
• Recognizing disability-specific mortality patterns is essential for effective support and premature mortality reduction efforts.
