Contraceptive outcomes among post-partum and post-abortal adolescents

Area of Science:

• Reproductive Health
• Adolescent Medicine
• Contraception

Background:

• Adolescent pregnancy and abortion pose significant public health challenges.
• Contraceptive method choice and adherence are critical for preventing unintended pregnancies in teens.
• Long-acting reversible contraceptives (LARCs) like Norplant implants offer potential benefits for this demographic.

Purpose of the Study:

• To evaluate the effectiveness and acceptability of Norplant implants compared to other contraceptive methods in adolescents post-pregnancy or post-abortion.
• To assess discontinuation rates and reasons for use among teen contraceptive users.
• To determine the incidence of subsequent unplanned pregnancies in relation to contraceptive method choice.

Main Methods:

• A prospective study involving 280 adolescents (ages 13-18) undergoing delivery or pregnancy termination.
• Participants chose either Norplant implants (n=92) or other methods (n=188).
• Telephone interviews were conducted at 1-year follow-up with subsets of users from both groups (n=78).

Main Results:

• Norplant implant users had significantly lower discontinuation rates (16%) compared to oral contraceptive (COC) users (47%) after 1 year (P < 0.03).
• Side effects were primary reasons for discontinuation in both groups; 'forgetfulness' or method failure led to discontinuation among some COC and condom users.
• No subsequent unplanned pregnancies occurred in the Norplant implant group, versus 25% in the COC group (P < 0.01).

Conclusions:

• Norplant implants are an acceptable and highly effective contraceptive option for adolescents following pregnancy or abortion, particularly for those motivated to avoid future unplanned pregnancies.
• While Norplant implants demonstrate superior adherence and pregnancy prevention, other methods are also chosen by teens.
• Enhanced counseling is crucial for adolescents selecting non-implant contraceptive methods to improve adherence and reduce unintended pregnancy rates.
