Duration of HPV infection was not a significant risk factor for spontaneous PTB <37 weeks.
Cervical HPV DNA and HPV serology may further delineate the relationship between HPV infection and SPTB <37 weeks.
A larger sample size may be necessary to show a difference.
The 3.5x higher rate of fetal death > 23 weeks in our study (compared to fetal death > 20 weeks in the U.S.) needs further investigation.
