Women, Be Kind to Your Bones and Joints

Steps to ensure strong, healthy bones in your golden years

It's important to make sure you're on track for good health if you're a woman in midlife. In fact, hitting the track could be just the thing to do.

According to Kathy Weber, MD, MS, a sports medicine specialist at Rush, the midlife years — 40s, 50s and 60s — are an important time for women to stay active and eat right for the long-term health of their bones and joints.

Sometimes it's hard to be a woman

The years can bring bone and joint problems for both men and women. Simple wear and tear can lead to osteoarthritis, and the weight gain that often comes with age puts even more stress on joints. 

For women, though, the story is more complicated. To begin with, a woman's bone mass is generally lower than a man's. And the decrease in estrogen that comes with menopause brings a higher risk for weak bones from osteoporosis.

Additionally, mechanical differences in the way women's thigh, hip and butt muscles are engaged — in combination with the angle between the hip and knee — puts them at a higher risk for injuries than men, especially injuries to the knee cap and anterior cruciate ligament, or ACL. In midlife, women are also at higher risk than men for overuse injuries, such as stress fractures and tendonitis.

Walk it off

With the extra risks women face, exercise might seem like a dangerous step. But the fact is, being fit is a good defense.

"If you don't exercise already, start now," Weber says. "Even 10 minutes a day is a good beginning."

A well-designed exercise program including aerobic exercise, stretching and lifting weights can help you avoid injuries. Weight-bearing activities, such as walking, jogging and dancing, can help keep bones healthy.

The secret is to begin slowly with an easy activity, such as walking, and build up to more strenuous exercise. Aim for at least 30 minutes of moderate-intensity physical activity — either all at once or 10 minutes at a time — on most days of the week.

But if it's been a while since you’ve been active, Weber advises talking to your doctor before you begin any exercise program to ensure you don't have any health problems that might make exercising risky. (Weber offers more advice on how to avoid injury while exercising in "Exercise Caution.")

Eating away at risk

In addition to regular moderate-intensity physical activity, a bone-healthy diet is essential.

"After about age 25, a woman's bone mass starts depleting instead of building, and menopause increases this loss," Weber says.

Calcium is the most important nutrient for bones, and vitamin D helps the body absorb it. In addition to finding both in dairy products and fish, some foods and beverages, such as orange juice, are fortified with calcium, and it’s in some green vegetables. The amount of calcium and vitamin D you need varies with age, so make sure you’re getting enough — but not too much — at each stage of your life.

A recent study of women in their 50s and 60s, published in the journal Menopause, suggests that moderate alcohol consumption — one to two drinks per day — may also help to prevent bone loss in older women.

The study revealed that moderate amounts of alcohol seem to slow down the bone turnover rate (the biological process by which bits of bone are dissolved, or reabsorbed, and new bone is formed). This slowdown may help protect women against fractures over time.

While further research is needed, these findings seem to fit with a prior discovery that people who are moderate drinkers have higher bone mineral density than heavy drinkers and those who don’t imbibe at all.

However, both the study authors and Weber caution that these potential bone-protective benefits don’t apply to men, or to girls and women in their teens and early 20s who are still building bone mass.

"If you're under the age of 25, you should focus on physical activity, eating right and getting enough calcium and vitamin D to ensure that your bones are healthy and strong," Weber says.

Taking a proactive approach to prevention 

Weber advises having a baseline bone density test, or DEXA scan, for all women at age 65, or earlier if you are at high risk for developing osteoporosis. This allows you to start treatment as soon as necessary.

A woman's risk is higher if she is postmenopausal, doesn't exercise, has a family history of osteoporosis, drinks large amounts of alcohol (more than one drink daily), has low body weight due to an eating disorder, has not menstruated for a long period of time and/or smokes.

To help women of all ages with joint problems, Rush offers both traditional and advanced care, including the following:

  • Joint replacement. Experts at Rush were instrumental in developing the first artificial knee designed specifically for women. It fits the narrower shape of women’s knees and accommodates the different angle at which a woman's knee moves over the end of the femur. Rush also offers highly specialized joint replacement procedures for the wrist and shoulder.
  • Joint resurfacing. This alternative to joint replacement preserves bone, meaning full joint replacement can be done later if necessary.
  • Therapies for osteoporosis. These include the latest medications and personalized diet and exercise counseling, such as can be found at the Rush Osteoporosis Treatment Center.
  • Smoking cessation programs. Nicotine and other chemicals in cigarette smoke can be toxic to bones.
  • Weight management programs. Being overweight puts extra stress on your joints.

More women than ever are healthy, active and strong at midlife and beyond, notes Weber. It's not too late to be one of them.

The greatest misconception about osteoporosis is that it is a disease of aging — the inevitable result of losing bone mass over the years. But bone health is a lifelong issue, and there are many factors that go into your risk of fractures, from genetics to lifestyle to medical conditions.

Our bodies continuously break down old bone tissue and form new bone tissue to replace it. But when bone tissue forms too slowly, breaks down too quickly, or both, bones become thin, fragile and prone to fracture.

Many rheumatoid arthritis sufferers believe that cold, damp conditions or changes in barometric pressure can aggravate their symptoms. But scientific evidence for this belief remains inconclusive says Andrew Ruthberg, MD, a Rush rheumatologist.
