Risk Factors for Chlamydia

A risk factor is something that increases your chances of getting a disease or condition.

Chlamydia is far more common in women than in men. The risk is highest among adolescents and young adults (generally up to age 25), who are more likely to take risks with their sexual behavior.

Chlamydia cannot be seen, so you cannot tell if someone has it. Since most people are unaware they are infected, chlamydia can get transmitted from person to person without your knowledge.

Other factors that may increase the chances of chlamydia:

• Multiple or frequent changes in sex partners
• Inconsistent or incorrect condom use —latex condom use helps prevent the spread of sexually transmitted infections (STIs)
• A history of chlamydia or other STIs—reinfection is common and can lead to serious reproductive complications
• Excessive alcohol or illegal drug use—increases the risk of risky sexual behavior
• Men having sex with men

Another risk factor for women is cervical ectropion, a condition where cells from inside the cervix are on the outside. Although it usually does not cause problems, it can make you more susceptible to infection.
