Sardines, yogurt, kale and almonds in daylight

The short answer

All women by 65 and men by 70, and earlier for anyone with risk factors. The key number is the T-score.

Get tested sooner if you had early menopause, a fracture after 50, a parent with a hip fracture, long-term steroid use, low body weight, rheumatoid arthritis, heavy smoking or drinking, or treatment for breast or prostate cancer that lowers hormones.

T-score of -1.0 or above: normal.

Between -1.0 and -2.5: osteopenia.

-2.5 or below: osteoporosis.

Your doctor can combine the score with your history in a calculator called FRAX to estimate your ten-year fracture risk, which is what should guide treatment.
