Osteoporosis 2010

Definition:Osteoporosis is defined by the World Health Organization (WHO) in women as a bone mineral density 2.5 standard deviations below peak bone mass (20-year-old healthy female average) as measured by DXA.

Osteoporosis 2010

The link between age-related reductions in bone density and fracture risk goes back at least to Astley Cooper.

8

Osteoporosis 2010

The term "osteoporosis" and recognition of its pathological appearance is generally attributed to the French pathologist Jean Lobstein .

9

Osteoporosis 2010

The American endocrinologist Fuller Albright linked osteoporosis with the postmenopausal state.

10

Osteoporosis 2010

A major U.S. public health threat for 44 million men and women over age 50.

Osteoporotic fractures responsible for:

• 500,000 Hospitalizations

• 800,000 ER visits

• 2.6 million physician visits

• 180,000 nursing home placements

11

Osteoporosis Prevalence in U.S.

Alabama = 2nd

Georgia = 11th

Florida = 22nd

12

Osteoporosis 2010

In 2005: > 2 million osteoporotic fractures reported.

Treatment Costs = $17 Billion

90% of all fractures due to underlying bone fragility.

50% of women and 25% of men will have an osteoporosis- related fracture during their lifetime

Practice Barriers and Gaps

Physicians do not discuss risk factors with patients

Diagnosis made most often after fracture

Fewer than 2/3 of women over 65 have had bone density test.

Only 20.4% of women over age 67 had BMD or preventive Rx within 6 months of fracture.

Non- adherence

Non-compliance

Audience Response Question

24

Risk Factors : Age

Age trumps BMD

Impact of age is at least 10x the risk of declining BMD.

25

Risk Factors: Fracture Hx

Prior forearm fracture = 2x risk

Women over 74 with vertebral fracture = 20% recur within a year.

Risk ratio only lowered slightly by BMD

26

Risk Factors: Genetics

The greatest influence on a woman’s peak BMD is heredity

Hip fracture risks 50% higher with first degree relative

127% higher if hip fracture occurred in a parent

27

Risk Factors: Weight and BMI

Weight under 127 lbs.

BMI < 21

Increases risk of low BMD and fracture, especially in older women

29

Risk Factors: Menopause

Peri-menopausal bone loss = 1-2% per year.

Women with menopause before age 40 (spontaneous or induced) are at greater risk of low BMD than menstruating cohorts (up to age 70).

30

Risk Factors: Medications

Glucocorticoids: 2x increase in risk

Depot MDA

Breast Cancer chemo agents

31

Risk Factors: Comorbidities

Hyperthyroidism

DM I

Ankylosing Spondylitis

Rheumatoid Arthritis

32

Lifestyle Approaches: Nutrition

Women over 60 do not consume the recommended servings of dairy products, fruits, vegetables or grains.

Healthy Eating Index score of these women is 67.4. Out of a possible 100.

33

Nutrition: Calcium

WHI: hip fractures significantly reduced in older women adherent to calcium/ vitamin D regimens.

Calcium intake declines with age.

Impaired absorption with age.

Optimal intake: 1200 mg. daily

35

Nutrition: Calcium

Dairy products supply 80% of calcium for women over 60.

High elemental calcium content.

High absorption rate

Cost- efficient

Spinach and wheat bran may inhibit absorption.

Audience Response Question

38

Nutrition: Vitamin D

Is actually a steroid pro-hormone rather than a vitamin.

Essential for intestinal absorption of calcium.

1000 IU daily.

Only food sources are fortified dairy products and fatty fish.

39

Nutrition: Vitamin D

SPF > 8 blocks 97.5% of Vitamin D production.

Low levels found in older, frail, chronically ill, housebound, or institutionalized women.

Higher risk of Vitamin D deficiency in northern latitudes.

40

Nutrition: Vitamin D

60% - 100% of patients will have a low level.

Over age 90: 100% are deficient.

Adequate Vitamin D levels associated with increased bone mass, decreased rates of falls, and significant reductions in fractures.

41

Nutrition: Magnesium

Most people over 40 are deficient in magnesium intake.

Intake falls severely after age 70.

Found in green leafy vegetables, grains, and nuts.

Severe deficiency can cause hypocalcemia and Vitamin D resistance.

No evidence to support use in prevention or treatment of osteoporosis.

44

Nutrition: Protein

For older women, protein supplement may:• Help minimize bone loss

• Shorten hospital stay for hip fracture and improve clinical outcomes.

• Significantly lower rates of complication and mortality up to 7 months post-fracture.

45

Nutrition: Isoflavones

Phytoestrogens found in soybeans, soy products and red clover.

No evidence to support use in prevention or treatment of osteopenia or osteoporosis.

46

Exercise

Weight –bearing and strength-training exercises are beneficial to bone development and maintenance.

Mild to moderate exercise confers benefits.

Exercise increased BMD 2% in PMP women.

Exercise and strength training = 75% reduction in falls and injuries for women over 75

47

Exercise

BMD in dominant arm of tennis players is greater than non-dominant arm.

48

Exercise

Walking

Jogging

Running

Strength-training exercises

49

50

Exercise

Target areas most involved in osteoporotic fractures:

• Large extensor muscles of the back

• Thigh

• Upper arms

• Forearm

51

Exercise

Water aerobics for the physically impaired.

Exercises to strengthen back extensor muscles reduce risk of spine fracture in women with and without prior fracture and improve quality of life.

Falls

Precipitating factor in 90% of fractures.

One- third of women over age 60 fall at least once a year.

Over age 80, fall rate is 80%

56

Falls

Risk Reduction:

Exercises to improve balance and muscle strength

Reducing fall hazards in the home

Adjusting medications (Tapering and discontinuing use of BZD’s, neuroleptics and anti-depressants found to reduce fall risk by 60%)

57

Alcohol Consumption

Moderate alcohol intake possibly associated with BMD.

Increased risk of falling and fracture with. 7 drinks a week.

Two or more drinks in 6 hours = 20% of falls in working adults.

Smoking Cessation

Compared to non-smokers, women smokers:

• Tend to lose bone more rapidly.

• Have lower BMD

• Reach menopause 2 years earlier.

• Have a higher fracture rate.

• Second hand smoke also a risk factor.

61

BMD Testing

All post-menopausal women with medical causes of bone loss.All women age 65 and over.Women age 50 and over with one of the following risk factors: 1. Previous fracture after menopause.2. BMI <213. Parental hip fracture4. Current smoker5. Rheumatoid Arthritis6. Excessive ETOH

63

Summary

Osteoporosis is everywhere.Most women over 65 have not had screening.Most patients with osteoporosis go untreated.Adherence and compliance are suboptimal and lead top poor outcomes.We need to improve our communications with patients.

64

Adherence and Compliance

Compliance: follows instructions about dose and interval.

Persistence: time from initiation to discontinuation.

Adherence: Persistence + compliance. (Refills)

Readability ScalesSMOG:To calculate SMOG1. Count a number of sentences (at least:10 from the start of a

text, 10 from the middle, and 10 from the end). 2. In those sentences, count the polysyllables (words of 3 or

more syllables). 3. Calculate using

A version is also given which is more easily used for mental

math and is sometimes known as the SMOG Index:1. Count the number of polysyllabic words, excluding proper

nouns, in a sample of thirty sentences. 2. Take the square root of the nearest perfect square 3. Add 3

Menopause__sometimes called the change of life__is a natural part of a woman's life. As you get older, your body produces less of the hormone estrogen. As you start making less estrogen, you may notice some physical changes like hot flashes or vaginal dryness. Having les natural estrogen may also be linked to certain serious health problems such as osteoporosis and heart disease. Inside, you will find comprehensive information about osteoporosis. The chart below describes some of the most common changes associated with menopause and ways in which you can manage the effects of these changes.
