To assess contraceptive discontinuation, switching, factors associated with method discontinuation, and pregnancy among women initiating hormonal contraceptives.
This was a 12-month longitudinal cohort study of adolescent girls and women (n=1,387) aged 15 to 24 years attending public family planning clinics who did not desire pregnancy for at least 1 year and selected to initiate the patch, ring, depot medroxyprogesterone acetate, or pills. Participants completed follow-up assessments at 3, 6, and 12 months after baseline. Life table analysis was used to estimate survival rates for contraceptive continuation. Cox proportional hazards models were used to estimate factors associated with method discontinuation.
The continuation rate (per 100 person-years) at 12 months was low for all methods; however, it was lowest for patch and depot medroxyprogesterone acetate initiators, 10.9 and 12.1 per 100 person years, respectively (P≤.003); continuation among ring initiators was comparable to pill initiators, 29.4 and 32.7 per 100 person-years, respectively (P=.06). Discontinuation was independently associated with method initiated and younger age. The only factors associated with lower risk of discontinuation were greater intent to use the method and being in school or working. The pregnancy rate (per 100 person-years) was highest for patch and ring initiators (30.1 and 30.5) and comparable for pill and depot medroxyprogesterone acetate initiators (16.5 and 16.1; P<.001).
The patch and the ring may not be better options than the pill or depot medroxyprogesterone acetate for women at high risk for unintended pregnancy. This study highlights the need for counseling interventions to improve contraceptive continuation, education about longer-acting methods, and developing new contraceptives that women may be more likely to continue.

    • "The high failure rate of short-acting contraceptive methods indicates a need to recommend LARC to young women, which once inserted can be forgotten.37,38 Many adolescent and nulliparous women prefer the IUD over non-LARC methods when they are properly informed about the advantages over short-acting methods.

    ABSTRACT: Background The purpose of this study was to provide additional data on the experience with frameless copper and levonorgestrel (LNG) intrauterine devices (IUDs) in nulliparous and adolescent women. Methods Nulliparous and adolescent women, 25 years of age or younger, using the frameless copper IUD or the frameless LNG-releasing intrauterine system (IUS), were selected from previous studies and a current multicenter post-marketing study with the frameless copper IUD. The small copper-releasing GyneFix® 200 IUD consists of four copper cylinders, each 5 mm long and only 2.2 mm wide. The frameless FibroPlant® LNG-IUS consists of a fibrous delivery system releasing the hormone levonorgestrel (LNG-IUS). The main features of these intrauterine contraceptives are that they are frameless, flexible, and anchored to the fundus of the uterus. Results One hundred and fifty-four nulliparous and adolescent women participated in the combined study. One pregnancy occurred with the GyneFix 200 IUD after unnoticed early expulsion of the device (cumulative pregnancy rate 1.1 at one year). Two further expulsions were reported, one with the GyneFix 200 IUD and the other with the FibroPlant LNG-IUS. The cumulative expulsion rate at one year was 1.1 with the copper IUD and 2.2 with the LNG-IUS. The total discontinuation rate at one year was low (3.3 and 4.3 with the copper IUD and LNG-IUS, respectively) and resulted in a high rate of continuation of use at one year (96.7 with the copper IUD and 95.7 with the LNG-IUS, respectively). Continuation rates for both frameless copper IUD and frameless LNG-IUS remained high at 3 years (>90%). There were no cases of perforations or pelvic inflammatory disease reported during or following insertion. Conclusion This report confirms earlier studies with frameless devices and suggests that the high user continuation rate is attributable to the optimal relationship between the IUD and the uterine cavity. IUD studies have shown that an IUD that does not fit well will often lead to side effects (ie, pain, bleeding, embedment, expulsion) and subsequent removal of the IUD. Early discontinuation is not the aim of long-acting reversible contraception.

    • "While LARC method used has increased recently in the US, most of the increase is among parous women (Finer et al., 2012; Kavanaugh et al., 2011). Although young women relying on user-dependent methods have elevated failure and pregnancy rates (Raine et al., 2011), these results showed that NPs often do not view adolescent and nulliparous women as IUD candidates, due to overly restrictive views of eligibility (Centers for Disease Control and Prevention, 2010; Deans and Grimes, 2009). Integrating long-acting contraception into NPs' counseling and clinical practice can help to prevent pregnancy and also rapid subsequent pregnancy among adolescent mothers and young women (Waggoner et al., 2012).

    ABSTRACT: Nurse practitioners (NPs) provide frontline care in women's health, including contraception, an essential preventive service. Their importance for contraceptive care will grow, with healthcare reforms focused on affordable primary care. This study assessed practice and training needs to prepare NPs to offer high-efficacy contraceptives - IUDs and implants. A US nationally representative sample of nurse practitioners in primary care and women's health was surveyed in 2009 (response rate 69%, n=586) to assess clinician knowledge and practices, guided by the CDC US Medical Eligibility Criteria for Contraceptive Use. Two-thirds of women's health NPs (66%) were trained in IUD insertions, compared to 12% of primary care NPs. Contraceptive counseling that routinely included IUDs was low overall (43%). Nurse practitioners used overly restrictive patient eligibility criteria, inconsistent with CDC guidelines. Insertion training (aOR=2.4, 95%CI: 1.10 5.33) and knowledge of patient eligibility (aOR=2.9, 95%CI: 1.91 4.32) were associated with IUD provision. Contraceptive implant provision was low: 42% of NPs in women's health and 10% in primary care . Half of NPs desired training in these methods. Nurse practitioners have an increasingly important position in addressing high unintended pregnancy in the U.S., but require specific training in long-acting reversible contraceptives.

    • "An earlier menarche means an earlier development of secondary sex traits and of reproductive capacity. Thus, a girl will start sporadic or steady dating relationships at an earlier time [35,36], a fact that, in turn, also favors an early start of sexual activity, which is not always accompanied by adequate means of prevention of pregnancy [37,38].

    ABSTRACT: Pregnancy in adolescence tends to repeat over generations. This event has been little studied in middle and low-income societies undergoing a rapid epidemiological transition. To assess this association it is important to adjust for socioeconomic conditions at different points in lifetime. Therefore, the aim of this study is to analyze the independent effect of adolescent childbearing in a generation on its recurrence in the subsequent generation, after adjusting for socioeconomic status at different points in life. The study was conducted on a prospective cohort of singleton liveborn females from the city of Ribeirao Preto, Brazil, evaluated in 1978/79, and their daughters assessed in 2002/04. A total of 1059 mother-daughter pairs were evaluated. The women who had their first childbirth before 20 years of age were considered to be adolescent mothers. The risk of childbearing in adolescence for the daughter was modeled as a function of the occurrence of teenage childbearing in her mother, after adjustment for socio-demographic variables in a Poisson regression model. The rate of childbearing during adolescence was 31.4% in 1978/79 and 17.1% in 2002/04. Among the daughters of the 1st generation adolescent mothers, this rate was 26.7%, as opposed to 12.7% among the daughters of non adolescent mothers. After adjustments the risk of adolescent childbearing for the 2nd generation was 35% higher for women whose mothers had been pregnant during adolescence -- RR = 1.35 (95%CI 1.04-1.74). Adolescent childbearing in the 1st generation was a predictor of adolescent childbearing in the 2nd, regardless of socioeconomic factors determined at different points in lifetime.
