Cardiovascular Disease and Hip Fracture among Older Inpatients in Beijing, China

الملخص EN

|Objectives.

To examine the associations between cardiovascular disease (CVD) and hip fracture and to determine if these associations are attributable to hypertensive disease.

Methods.

Data were obtained from 2006–2010 hospitalization summary reports of 31 tertiary hospitals in Beijing, China.

This study included 864,408 inpatients aged ≥55 years.

Occurrence rate of hip fracture was based on the first-listed ICD-10 codes (S72.0, S72.1, and S72.2) and of CVD as comorbidities were based on the second- to the eighth-listed ICD-10 codes (I00–I99).

Results.

The occurrence rate of hip fracture is 53% higher among older inpatients with a diagnosis of CVD than those without (RR=1.53, 95% CI 1.47–1.60).

Those with hip fracture were more likely to have hypertensive or cerebrovascular disease, with the risk ranging from 1.34 to 1.70.

Compared with those without hip fracture, the occurrence rate of overall CVDs increased by 80%, 83%, and 16% among hip fracture patients aged 55–64, 65–79, and ≥80 years.

In addition, hypertensive disease did not modify the association between cerebrovascular disease and hip fracture.

Conclusion.

CVD was positively associated with hip fracture, and the associations observed in this sample of Chinese inpatients were similar to those reported from cohort studies conducted in the European populations.
