(CNN) - More and more older people are getting sexually transmitted diseases.
That's coming from a new study published in the British Medical Journal.
Researchers say 80 percent of people 50 to 90 years old are sexually active.
And cases of sexually transmitted diseases among this age group have more than doubled in the past 10 years.
Researchers say older women tend to be more vulnerable to STDs because of post-menopausal changes.
