Powerful Bones, Powerful Girls (cont.)

Lifetime Prescription for Powerful Bones

Infants to Teens

Calcium. The American Academy of Pediatrics recommends the following amount of calcium for children:

  • 210 mg for infants up to 6 months old
  • 270 mg for infants 6 months to 1 year
  • 500 mg for toddlers 1-3 years
  • 800 mg for children 4-8 years
  • 1,300 mg for children 9-18 years

Exercise. Kids should be getting at least 30 minutes of exercise three or four times a week.

No Smoking.

Young Adults

Calcium/Vitamin D. By the time she's 25, a woman should be taking 1,000 mg of calcium in supplement form, says Esses. "Supplements are the best way for a female to be certain she's getting adequate calcium." If she becomes pregnant, her calcium intake requirements increase to 1,200 mg; it's 2,400 mg when she is breastfeeding.

Exercise. Thirty minutes, three times a week, is the minimum. Women should do weight-bearing exercise, especially walking, as well as strength-training exercises using hand weights.

No Smoking.

Life After 30

As you lose bone density, your risk of breaking a bone -- especially in the hip, spine, or wrist -- increases significantly. Bone loss can start when a woman hits her 30s, recent studies have shown.

Estrogen. Women should talk to their doctors about hormone replacement therapy, says Esses. "Although there is lot of controversy over hormonal supplementation, there's no question that HRT at the time of menopause is important in maintaining bone mass.

"Unless there are specific risk factors for taking hormones, like a history of cancer, there is overwhelming evidence that suggests [HRT] can be taken safely to prevent osteoporosis," he says.

Medications. For those who can't take hormones, there are other medications that can be used to protect bone mass. Medications such as Evista, Fosamax, or Actonel are effective in preventing or treating osteoporosis, says Esses.

Just don't wait too long to start. "I often see people who have had a hysterectomy and who were not given any estrogen, and 10 years later they've missed the boat," Esses tells WebMD. "You must start HRT within three years of whatever event, whether menopause or hysterectomy."

Calcium/Vitamin D: 1,000 mg

Exercise: 30 minutes, three times a week of weight-bearing and strength-training exercises.

No Smoking.

Older Adults

Bone Density Study. "Before they have a break, it would be worthwhile for females in their 60s to get a bone density study -- to see if they have osteoporosis," says Esses.

Medications. If bone density study shows deterioration, take osteoporosis-treatment medications.

Calcium/Vitamin D: For women, 1,500 mg a day. If she's on estrogen replacement, calcium intake should be 1,000 mg a day.

Although less common, men can also get osteoporosis and also need to watch their calcium intake. Men should be sure to take in 1,000 mg a day until age 65 and then 1,500 mg a day after that.

Exercise: 30 minutes, three times a week of weight-bearing and strength-training exercises. Even women in their 70s, 80s, and 90s can benefit from starting an exercise program, research shows.

Also, if women have a fracture, it's important that their osteoporosis also get medical attention, says Esses. "Here's a startling piece of information: nearly all patients admitted to hospitals with spine and hip fractures get sent home without treatment for their osteoporosis."

"It's never too late to strengthen your bones," Mark tells WebMD. "Bone is living tissue, it's always replacing itself. We can't give you what you missed; if you never built up much bone mass, you can't build it later. But you can strengthen what you've got."
