[Human papilloma virus and Chlamydia trachomatis by number of sexual partners and time of sexual activity on university students in the Region of La Araucanía, Chile].
BACKGROUND
Human papilloma virus (HPV) and Chlamydia trachomatis are the most prevalent sexually transmitted infections (STIs), among teenagers and young people, with risk factors: active sex life and multiple partners. Chlamydia trachomatis infection may favor HPV infection and this, the development of cervical cancer. Both infections can lead to consequences on sexual and reproductive health.


OBJECTIVE
To determine frequency of HPV and C. trachomatis in asymptomatic university women less than 25 years, associating them with number of sexual partners (n°SxP) and time of sexual activity (TSxA). Material andMethods: 151 cervical samples for HPV and C. trachomatis, were processed by conventional and in real time reaction polymerase chain.


RESULTS
HPV 21, 8%, C. trachomatis 11, 2% and co-infection (HPV/C.trachomatis), 4.6%. Aimong HPV +, 80, 6% showed high risk HPV. The n°SxP was strongly associated with HPV. Aimong young coinfected HPV/C. trachomatis, 71.4% had 3 or more PSx. Chlamydia trachomatis was more frequent (64,7%) that HPV within range of 3-5 years according to the TSxA, Discussion: A high prevalence of HPV and C. trachomatis was observed. Young women with coinfection HPV/C. trachomatis could be a high-risk group need to monitor their infections. It suggests the implementation of university programs in education, counseling and prevention in sexual health.
