· Almost 7500 sexually active women in St. Louis could have their choice of free contraception for up to 3 years (1)
· They only had to not want to get pregnant for at least one year and be willing to listen to all the risk and benefits of all available common contraceptives
· They could then have their choice of all the methods and switch if they were unhappy with their choice
· This was the first prospective large US multi-year study that compared the outcomes of the pregnancy rates and satisfaction with the most popular contraceptive methods currently available with no cost consideration
· The main author was Dr Jeff Peipert and was paid for by the Susan Buffett Foundation
· The average US teen has sex for the first time when they are 18 years old (2)
· This is no different than Europe, Canada, and Mexico
· The only difference is that US teens have a much higher unplanned pregnancy and abortion rate (3,4)
· Lack of adequate sex education in US schools is one of the major differences
· Failure rates of long-acting reversible contraception [LARC] (intrauterine devices [IUDs] and implants) were compared to the most commonly used contraceptive, “the pill”
· One half of failures causing unplanned pregnancies is the incorrect or inconsistent use of the method (5)
· “Forgettable contraception” like LARC takes these failures “off the table”
· The implant (Nexplanon) and IUDs do not require you to remember anything
· The failure rate for the pill, patch, or ring was 20 times higher than LARC (1)
· LARC users had over 80% continuous use at 12 months compared to 50% for the pill (6)
· Satisfaction with the two groups was also similar (IUDs 80%; the pill 54%) (6)
· For a more detailed description of individual methods please see Bedsider (7)
