Relationship between patient characteristics and serum etonogestrel concentrations in contraceptive implant users.

ABSTRACT:

Objective

To determine whether serum etonogestrel concentrations in contraceptive implant users are associated with certain individual patient characteristics.

Study design

We enrolled reproductive-age women using etonogestrel contraceptive implants between 12-36 months duration and measured a single serum etonogestrel concentration. Participants also completed a questionnaire about demographics.

Results

We enrolled 350 participants; median age was 22.5 years (range 18.0-39.1), median months of implant use was 26.0 (range 12.0-36.0), and median body mass index was 25.7 kg/m² (range 18.5-52.0). Our study population was primarily white/Caucasian (46.6% [163/350]) and Hispanic/Latina ethnicity (51.4% [180/350]). The median serum etonogestrel concentration was
