[Contraception for adolescent : CNGOF Contraception guidelines]

Abstract

Objective: The goal is to establish dialogue and determine the needs and skill levels of adolescence. This concerns sexuality, the prevention of STIs, the informed choice of contraception to avoid an unplanned pregnancy. MéTHODES: A systematic review based on literature about contraception AND teenagers was performed using Pubmed, Cochrane, national and international recommendations.

Results: The surveillance of the teenager contraception must integrate more specifically: global health with a stability of weight and corpulence, a sufficient calcium intake, the prevention of the sexually transmitted infections (STIs) and the vaccination against HPV. The 1st consultations with adolescent girls are an essential moment for dialogue in order to develop sexuality education. Main themes are: prevention of STIs with the use of condoms, detection of situations of precariousness or sexual abuse, and finally adherence to treatment to avoid unplanned pregnancy. Use of condoms associated with regular contraception is essential to assure a barrier against sexually transmitted infections (STIs) (NP1). To preserve the patient confidentiality, the patient is received alone (Grade B). She must be reassured about respect of anonymity and availability of free treatment. Clinical examination collects weight, height, BMI and blood pressure (Grade C). It is important to give them the choice of contraceptive method and provide objective information on the different contraceptive methods (NP2). If there are any contraindications, when the first prescription is a pill, it must be a 1st or 2nd generation pill with levonorgestrel. For some experts, it would be important to prescribe a pill at 30μg EE for better efficacy in case of forgetfulness in very young patients and for the good maintenance of bone mineralization (NP4). Information on long-acting reversible contraceptives, or LARCs, is essential. These contraceptive methods have proved their efficacy and their place in the first intention. (NP1).

Conclusion: Prescribing contraception to a teenage girl requires the adaptation of the best treatment to her needs to prevent an unwanted pregnancy. This requires good information on prevention of STIs and on different methods of contraception in a confidence climate.
