The male sexual partners of adult versus teen women with sexually transmitted infections

Sexual risk factors for partner age discordance in adolescent girls and their male partners

AIMS AND OBJECTIVES

To investigate differences in sexual risk factors between adolescent girls reporting similar-aged or older sex partners.

BACKGROUND

Adolescent girls are at significant risk of heterosexual-acquired HIV infection and other long-term reproductive health issues. Sexual partner age discordance in teen girls has been correlated with STIs, lack of protection, multiple partners and earlier age of sexual transition.

DESIGN

A descriptive study comparing girls currently involved with age-discordant partners to those with similar-aged partners. Two-sample t-test for continuous variables and chi-squared test or Fisher's exact test for categorical variables were used to compare groups.

METHODS

Baseline data from 738 sexually active, urban, adolescent girls aged 15-19 were analysed to determine which behaviours were more likely to occur in girls with older partners. Data were collected as part of a gender-specific HIV-prevention intervention in a randomised controlled trial (RCT) tailored to adolescent girls.

RESULTS

Multiple reported sexual risk behaviours were found to significantly differ between the two groups at baseline. Overall, girls with older partners had more episodes of sexual instances (vaginal, anal and oral). Specific sexual risk behaviours were found to be statistically significant between the two groups. Girls with older partners started having sex at earlier ages, had more lifetime sexual partners, higher incidents of STIs and were reluctant to discuss using condoms with their partners. Girls with similar-aged partners were less willing to engage in risky sexual behaviours.

CONCLUSIONS

Findings from this investigation support data from other studies. Relationships with older male partners place adolescent girls at increased risk of HIV/STIs and unintended pregnancy.

RELEVANCE TO CLINICAL PRACTICE

Adolescent girls in age-discordant relationships are at risk of immediate and long-term sexual health morbidities. Identifying girls who are at increased risk by asking tailored questions will enable nurses to recommend appropriate diagnostics for this population and provide age-specific counselling.

Conventional Agar-Based Culture Method, and Nucleic Acid Amplification Test (NAAT) of the cppB Gene for Detection of Neisseria gonorrhea in Pregnant Women Endocervical Swab Specimens

Background

Neisseria gonorrhea is the etiological agent of the sexually transmitted disease (STD) gonorrhea, and primarily infects the mucous membranes of the urethra, endocervix, pharynx or rectum of females which may result in substantial morbidity. N. gonorrhea also causes disseminated infection, with complications that may result in ectopic pregnancy, tubal infertility, chronic pelvic pain or maternal transmission of gonorrhea, and also increases susceptibility to HIV.

Objectives

In the present investigation, we used conventional agar-based culture method, and nucleic acid amplification of CCPB gene for detection of Neisseria gonorrhea in endocervical swabs samples collected from pregnant women studied

Patients and Methods

Endocervical swabs specimens for this study were obtained from 1100 pregnant women who presented to Shiraz (Iran) Hospitals from 2009 to 2011. In the present investigation we used conventional agar-based culture method, and nucleic acid amplification test (NAAT) of CCPB gene for detection of Neisseria gonorrhea in endocervical swabs samples collected from pregnant women studied. From each pregnant woman two endocervical swabs were taken: one swab placed in tubes containing phosphate buffered saline for Polymerase Chain Reaction, and the other to inoculate on culture media.

Results

Among 1100 endocervical swabs examined, 13 (1.18%) samples had positive results by polymerase chain reaction (PCR) on Neisseria gonorrhea CCPB gene. All endocervical swabs culture had negative results for Neisseria gonorrhea. 84 (7%) of the women had vaginal discharge, in whom PCR on endocervical swabs of these individuals had negative findings.

Conclusions

Nucleic acid amplification tests (NAATs) are very appropriate in detection of infected individuals. Detection techniques such as NAATs are independent of bacterial viability, and have a potential to limit false negative samples, therefore, in our country, the application of different laboratory diagnosis methods including NAATs with culture as gold standard for determination antimicrobial susceptibility is essential.
