Download Osteoporosis in the elderly & Public Health

Osteoporosis Educational Series, Lecture 1of 3:
A Public Health Problem of Older Age
Nahid Rianon, M.D., Dr.P.H.
The University of Texas Health Science Center at Houston
Goal and Objectives
GOAL: The goal of this presentation is to demonstrate the public
health importance of osteoporosis as a disease of old age and
the clinical definition of osteoporosis
LEARNING OBJECTIVES:
At the end of this presentation, attendees will be able to
– Learn the clinical definition of osteoporosis.
– Describe the health impact of osteoporotic fractures from
an individual to health care system level.
– Identify the generally recommended DEXA site to diagnose
osteoporosis.

Osteoporosis in the Elderly

Osteoporosis & related fractures - important public health
problems of old age

~10 million Americans suffers from osteoporosis

~34 million are at risk

More than 2 million fractures in
the USA in 2005 were attributable
to osteoporosis



547,000 vertebral fractures
297,000 hip fractures
397,000 wrist fractures
Osteoporotic Fractures
For Women:
 Incidence of fractures per year
exceeds that of stroke,
myocardial infarction (MI) and
breast cancer combined
For Men:
 Fracture risk is higher
than that of prostate
cancer


~1:2 Caucasian women ≥ 50
years experience a fracture in
their lifetimes


1 in 3 for vertebral fractures
1 in 6 for hip fracture
21% ≥ 50 years will
experience a fracture
Osteoporotic Fractures: Where and How

Common sites:


Vertebral body,
femur neck &
wrists
Fractures without
much force or any
trauma:

Turning in bed, fall
from a standing
height
Osteoporosis and Health Care Events
Health Care Cost
~$22 billion is spent annually for osteoporosis
and related fracture in the USA
~$7 billion is spent annually for breast cancer in
the USA
Osteoporosis and Quality of Life
Fractures can decrease quality of life:
 Physical: pain, compressed abdomen, spinal deformity
 Functional: decreased mobility
 Psychosocial: depression
 Rate of recurrent vertebral fracture after the initial one ~5-20%
Osteoporosis and Quality of Life
If one survives a hip fracture —
~50% with hip fractures will never walk without assistance
~25% will require long-term care
Osteoporosis: Measure of Bone Health
Revised definition:
Compromised bone strength that increases
risk of fracture NIH Consensus Conference 2000

Bone Strength is characterized by


Bone density and
Other bone qualities, e .g., micro-architecture influenced by bone
remodeling, bone turnover, mineralization and other factors that are
more difficult to quantify, such as “damage accumulation”
Clinical Diagnosis of Osteoporosis
Usual sites for DEXA is lumbar spine and left hip
DEXA scan - Left hip
DEXA scan - Lumbar spine
Osteoporosis = A T- score of <-2.5 for BMD
Osteopenia = A T- score of -1 to -2.5 for BMD
BMD Decreases with Advanced Age
