Older Women at Greater Risk for Common STD, Study
TUESDAY, July 12 (HealthDay News) -- The sexually transmitted
disease trichomoniasis may be much more common among older women
than those in their 20s, and researchers are recommending routine
screening for sexually active women aged 40 and older.
"We usually think of STDs as more prevalent in young people, but our study results clearly show that with [trichomoniasis], while too many young people have it, even more, older women are infected," said the study's senior study investigator, Charlotte Gaydos, professor at the Johns Hopkins University School of Medicine, in a university news release.
Trichomoniasis (commonly known as "trich") is caused by the
Trichomonas vaginalis. It is the most common sexually transmitted disease in the United States, according to the Centers for Disease Control and Prevention (CDC). The World Health Organization estimates that 173 million people worldwide become infected every year.
The study, slated for presentation Tuesday at the annual meeting
of the International Society for STD Research in Quebec City,
Canada, also revealed that black women were more than three times
as likely to be infected as whites (20 percent vs. 5.7 percent).
The study authors speculated that differences in income, education
and employment could explain this disparity.
The infection is easily cleared up with antibiotics. If left
untreated, however, trichomoniasis can lead to severe health
problems, such as pelvic inflammatory disease or complications
during pregnancy, such as premature labor.
In studying 7,593 U.S. women 18 to 89 years old across 28
states, the researchers found that 8.7 percent tested positive for
trichomoniasis, but the STD was more prevalent among older women.
Thirteen percent of women 50 and older had the parasite, and women
in their 40s trailed closely behind with an 11 percent infection
rate, the study found.
Women in their 20s, on the other hand, had an infection rate of
"Trichomonas infections are quite treatable with antibiotics," said Gaydos. "And these high numbers really warrant older women getting screened by their family physicians and gynecologists during routine check-ups to make sure they are not infected and are not inadvertently spreading it to others."
Infected people may not experience symptoms, which typically
include liquid discharge from the vagina or penis, irritation while
urinating and genital itching.
"What we are really witnessing with trichomonas, especially in older women, is that no one ever looked, no one ever tested and diagnosed, and no one is really getting treated, so the infection persists year after year," said Gaydos. The study authors added that federal agencies should require that trichomoniasis be reported to the CDC like other STDs, such as chlamydia and gonorrhea, so that public health officials can better track and prevent the condition.
Men should also be tested and treated for trichomoniasis to
reduce the risk of re-infection, particularly in situations
involving multiple sex partners, the authors said.
Experts note that research presented at meetings is considered
preliminary because it has not been subjected to the rigorous
scrutiny required for publication in a peer-reviewed medical
