Course Objectives

At the conclusion of this course, students will be able to:

1. Understand the roles bones play in the body2. Define the term "peak bone mass"3. Recognize that osteoporosis leads to low bone mass

and deterioration of bone tissue4. Name the risk factors for osteoporosis5. Understand the role that diet and exercise play in

preventing osteoporosis

Introduction

A healthy skeletal system with strong bones is essential to overall health and quality of life.

However, many Americans suffer from bone disease and fractures, much of which could be prevented.

Statistics from the Surgeon General

• An estimated 10 million Americans over age 50 have osteoporosis (bone disease)

• 34 million Americans are at risk for osteoporosis

• An estimated 1.5 million people each year suffer an osteoporosis-related fracture

• 20% of senior citizens who suffer a hip fracture die within one year

• One out of every two women over 50 will have an osteoporosis- related fracture in their lifetime

• Due primarily to the aging of the population and the previous lack of focus on bone health, the number of hip fractures in the U.S. could double or even triple by the year 2020.

Statistics from the Surgeon General

Hope is not lost. Over the past several decades, scientists have learned a significant amount about the prevention, diagnosis, and treatment of bone disease. Our next and most critical step is to transfer this knowledge from the research laboratories to the general population.

Bone Health

Bones play many roles in the body. They provide structure, protect organs, anchor muscles, and store calcium. Adequate calcium consumption and weight-bearing physical activity build strong bones, optimizes bone mass, and may reduce the risk of osteoporosis later in life.

Peak Bone Mass

Peak bone mass refers to the genetic potential for bone density. By the age of 20, the average woman has acquired most of her skeletal mass. A large decline in bone mass occurs in older adults, increasing the risk of osteoporosis.

For many women, the risk of osteoporosis occurs around

the time of menopause.

Bone Health

Peak Bone Mass

It is important for children, particularly girls, to reach their peak bone mass in order to maintain bone health throughout life. A person with high bone mass as a young adult will be more likely to have a higher bone mass later in life. Inadequate calcium consumption and lack of physical activity early on could result in a failure to achieve peak bone mass in adulthood.

Osteoporosis

Osteoporosis or "porous bone" is a disease of the skeletal system characterized by low bone mass and deterioration of bone tissue. Osteoporosis leads to an increased risk of bone fractures typically in the wrist, hip and spine.

Osteoporosis Risk Factors

While men and women of all ages and ethnicities can develop osteoporosis, some of the risk factors include those who are:

• Female

• White/Caucasian

• Post-menopausal women

• Older adults

• Small in body size

• Eating a diet low in calcium

• Physically inactive

Bone Health

Calcium

Calcium is a mineral needed by the body for healthy bones, teeth, and proper function of the heart, muscles, and nerves. The body cannot produce calcium; therefore, it must be absorbed through food. Good sources of calcium include:

• Dairy products – low fat or nonfat milk, cheese and yogurt

• Dark green leafy vegetables – bok choy and broccoli

• Calcium-fortified foods – orange juice, cereal, bread, soy beverages, and tofu products

• Nuts - almonds

Calcium

The recommended amount of calcium varies for individuals. Below is a table of adequate intakes as outlined by the National Academy of Science:

Ages Amount mg/day

19-50 years 1000

51 or older 1200

Pregnant & Lactating

Bone Health

Weight-Bearing Physical Activity

Like proper calcium consumption, adequate weight-bearing physical activity early in life is important in reaching peak bone mass. Some examples of weight-bearing activities include:

• Walking, jogging, hiking, and running

• Tennis, racquetball, basketball, and soccer

• Stair climbing

• Jumping rope

• Dancing

• Weight-lifting

Bone Health

Weight-Bearing Physical Activity

Incorporating weight-bearing physical activity into an exercise plan is a great way to keep bones healthy and meet physical activity recommendations set forth in the Dietary Guidelines for Americans.

Weight-Bearing Physical Activity

ADULTS

Should engage in at least 30 minutes of moderate physical activity on most, preferably

all, days of the week.

Weight-Bearing Physical Activity

CHILDREN

Should engage in at least 60 minutes of moderate physical activity on most, preferably

all, days of the week.

Medical Options

So, is there something else you can do, besides diet and exercise, to help prevent and treat osteoporosis?

Absolutely! Your health services professional may recommend that you undergo a bone density test, particularly if you're a member of a group that has a high risk of osteoporosis.

Patient undergoing a bone density test.

Medical Options

How does the test work?

A bone density test uses special X-rays to measure how many grams of calcium and other bone minerals - collectively known as bone mineral content - are packed into a segment of bone.

The higher your mineral content, the denser your bones. And the denser your bones, the stronger they generally are and the less likely they are to break.

Doctors use a bone density test to determine if you have, or are at risk of, osteoporosis.

Medical Options

Medications are also available that can help stabilize and restore bone density, and decrease the risk of fractures.

There are two types of drugs used to treat osteoporosis:

• Antiresorptive Drugs: These drugs block resorption (bone break down) and slow the rate of bone remodeling, but they cannot rebuild bone.

• Anabolic, or Bone-Forming, Drugs: These drugs rebuild bone.
