Abstract Individuals with cerebral palsy (CP) manifest skeletal fragility problems early in life and are vulnerable to nontrauma fracture (NTFx), which may exacerbate the risk of respiratory disease (RD)– the main cause of premature mortality for this population. The purpose of this study was to determine if adults with CP had a greater 12‐month risk of RD post‐NTFx compared to adults without CP. Data from 2011 to 2017 were leveraged from Optum Clinformatics Data Mart; a claims database from a single private payer in the United States diagnostic codes were used to identify adults (≥18 years) with and without CP, NTFx, incident RD, and pre‐NTFx cardiometabolic diseases. Cox proportional hazards regression models were used to compare 12‐month RD incidence following NTFx with adjustment for sociodemographics and cardiometabolic diseases. Mean age (SD) at baseline was 57.5 (18.4) for adults with CP (n = 646) and 61.8 (19.7) for adults without CP (n = 321,482). During the follow‐up, 172 adults with CP (26.6%) and 73 937 adults without CP (23.0%) developed RD. Adults with CP had higher 12‐month post‐NTFx RD incidence compared to adults without CP (hazard ratio [HR] = 1.20; 95% confidence interval [CI] = 1.03‐1.37). When stratified by the RD subtype, adults with CP had a higher incidence of pneumonia (HR = 2.15; 95% CI = 1.56‐2.95), interstitial/pleura disease (HR = 2.13; 95% CI = 1.53‐2.96), and other RD (eg, respiratory failure; HR = 2.33; 95% CI = 1.82‐2.98), but not acute respiratory infection (HR = 0.93; 95% CI = 0.75‐1.15) or chronic obstructive pulmonary disease (HR = 1.15; 95% CI = 0.86‐1.53). Among privately insured adults with CP, NTFx is associated with greater risk of RD among adults with vs without CP.
