Adolescent/Young Adult Long-Acting Reversible Contraception: Experience from a Multisite Adolescent Medicine Collaborative.

OBJECTIVE: To report on long-acting reversible contraception (LARC) experience and continuation rates in the Adolescent Medicine LARC Collaborative. STUDY DESIGN: LARC insertion data (682 implants and 681 intrauterine devices [IUDs]) were prospectively collected from January 1, 2017, through December 31, 2019, across 3 Adolescent Medicine practices. Follow-up data through December 31, 2020, were included to ensure at least 1 year of follow-up of this cohort. Continuation rates were calculated at 1, 2, and 3 years, overall and by Adolescent Medicine site, as were descriptive statistics for LARC procedural complications and patient experience. RESULTS: Implant and IUD insertion complications were uncommon and largely self-limited, with no IUD-related uterine perforations. Uterine bleeding was the most frequently reported concern at follow-up (35% implant, 25% IUD), and a common reason for early device removal (45% of implant removals, 32% of IUD removals). IUD malposition or expulsion occurred following 6% of all insertions. The pooled implant continuation rate at 1 year was 87% (range, 86%-91% across sites; P = .63), 66% at 2 years (range, 62%-84%; P = .01), and 42% at 3 years (range, 36%-60%; P = .004). The pooled IUD continuation rate at 1 year was 88% (range, 87%-90% across sites; P = .82), 77% at 2 years (range, 76%-78%; P = .94), and 60% at 3 years (range, 57%-62%; P = .88). CONCLUSIONS: LARC is successfully provided in Adolescent Medicine clinical settings, with continuation rates analogous to those of well-resourced clinical trials. Uterine bleeding after LARC insertion is common, making counselling imperative. Future analyses will assess whether the medical management of LARC-related nuisance bleeding improves continuation rates in our Adolescent Medicine patient population.

Health Outcomes of Youth in Clinical Pediatric Weight Management Programs in POWER.

OBJECTIVE: To describe treatment outcomes of children and adolescents enrolled in the Pediatric Obesity Weight Evaluation Registry, a consortium of multicomponent pediatric weight management programs in the US. STUDY DESIGN: This multicenter prospective observational cohort study, established in 2013, includes youth (2-18 years of age) with obesity enrolled from 31 Pediatric Obesity Weight Evaluation Registry (POWER) sites over a 2-year period and followed up to 12 months. Weight status was evaluated by the percentage of the 95th percentile for body mass index (%BMIp95). Associations of weight status outcomes with patient characteristics and program exposure were analyzed with multivariable mixed effects modeling. RESULTS: We included 6454 children and adolescents (median age, 11 years; IQR, 9-14 years; 53% white, 32% Hispanic; 73% with severe obesity) who were enrolled in POWER. Median changes in %BMIp95 for this cohort were -1.88 (IQR, -5.8 to 1.4), -2.50 (IQR, -7.4 to 1.8), -2.86 (IQR, -8.7 to 1.9), at 4-6, 7-9, and 10-12 of months follow-up, respectively (all P < .05). Older age (≥12 years), greater severity of obesity, and Hispanic race/ethnicity were associated with better improvement in %BMIp95. A 5-percentage point decrease in %BMIp95 was associated with improvement in cardiometabolic risk factors. CONCLUSIONS: Overall, treatment in pediatric weight management programs is associated with a modest median decrease in BMI as measured by change in %BMIp95. Further studies are needed to confirm these findings, as well as to identify additional strategies to enhance the effectiveness of these multicomponent interventions for youth with severe obesity.
