Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Summary

Disability significantly increases in the 2 years before hip fracture, especially in the final months. This highlights the need for integrated care models that address chronic disability alongside acute needs.

Background:

Hip fractures are a major cause of morbidity and mortality in older adults.
Understanding pre-fracture disability is crucial for improving patient outcomes and care planning.

Purpose of the Study:

To determine the prevalence and associated factors of disability in the two years preceding a hip fracture.
To analyze disability trends leading up to a hip fracture event.

Main Methods:

Utilized data from the Health and Retirement Study (HRS), a nationally representative longitudinal study.
Identified hip fractures using linked Medicare claims for participants aged 65 and older.
Defined disability as self-reported need for assistance with activities of daily living (ADLs).

Main Results:

Disability prevalence was 20% two years before hip fracture, rising to 44% in the month prior.
Disability prevalence increased significantly around 10 months before the fracture.
The highest disability rates were observed in individuals aged 85+ (53%) and those with dementia (60%) in the month before fracture.

Conclusions:

Care models for hip fracture must integrate supportive care and caregiver assistance for chronically disabled individuals.
Pre-fracture disability assessment is essential for comprehensive hip fracture management.
Findings underscore the importance of addressing long-term care needs in older adults at risk for hip fracture.
