This study will create a model of reproductive health services for HIV-positive female adolescents in Asia.

For the implementation of risk reduction interventions, it is equally important to provide specific knowledge and continuous counseling on different preventive options. A perfect preventive method, which provides highly reliable dual protection both from unintended pregnancies and from HIV/STDs with no side effects and which is completely accepted, is not available. Many authors consider that the most effective way to achieve dual protection is the simultaneous use of two contraceptive methods, one of which is a barrier method such as the male or female condom, and the other a highly effective contraceptive method, such as hormonal contraception (HC), intrauterine device (IUD) or sterilization. This is called dual contraception. Therefore this project will focus on specific reproductive service delivery for these groups of patients. As the age group is very young, the investigators will use in the study only reversible highly effective methods of contraception - HC, combined or progestin only, and an IUD - and condoms. For example, HC for HIV-positive women has been studied extensively in the last two decades, yet there are still no definitive answers regarding key issues - HIV disease progression, genital tract HIV shedding and infectivity, pharmacokinetic (PK) interactions between hormones and ARVs, and therefore a possibility for compromise of contraceptive effect and/or ARV failure, and last but not least, metabolic outcomes. Data on the effect of hormonal contraception on HIV disease progression is still inconclusive. Unfortunately there is only a limited number of studies in this field, with very small sample sizes and in most cases outside "real life" conditions.

There are three substudies:

1. Pharmacokinetic interactions between the sex steroid hormones and the protease inhibitors in HIV-positive Thai female adolescents
2. Assessment of premenstrual syndrome in HIV-positive adolescents
3. Metabolic changes in HIV + female adolescents on ART with hormonal contraception
