          Abstract

          RESUMEN Objetivo: Analizar el efecto sobre el peso corporal de la anticoncepción hormonal continua mediante implante sub-dérmico liberador de etonogestrel (ENG) en mujeres en edad reproductiva atendidas en la consulta de planificación familiar de un hospital venezolano. Métodos: Investigación comparativa, con diseño cuasi experimental, de casos y controles, a etiqueta abierta, y prospectivo; con una muestra intencionada de 60 mujeres separadas para recibir bien sea un implante subdérmico (Implanon NXT®; casos) o un dispositivo intrauterino (DIU) de cobre (T de cobre; controles). Se evaluaron el peso corporal e índice de masa corporal antes y posterior de doce meses del uso del contraceptivo; así como las características demográficas de las usuarias, efectos adversos y efectividad anticonceptiva de cada método. Resultados: Luego de un año con el implante de ENG no se encontraron variaciones significativas respecto a las mediciones iniciales del peso corporal (61,21±8,30 vs. 61,23±9,50, p>0,5) e IMC (25,23±3.89 vs. 25,26 ±4,30; p>0,05); contrariamente, a lo observado entre las usuarias del DIU donde tanto el peso corporal como el IMC tuvieron un aumento significativo (P<0,05). Asimismo, la mayoría de las usuarias se mantuvieron en el mismo rango de peso donde se encontraban al iniciar el método (p<0,001); mientras que la ganancia ponderal fue mayor entre las usuarias del DIU (1,530±2,04 vs. 3,700±3,02; p<0,05). Conclusiones: El implante de ENG no produce aumento del peso corporal luego de 12 meses de uso, con mínimos efectos adversos y alta efectividad contraceptiva.

          ABSTRACT Aim: To analyse the effect on body weight of continuous hormonal contraception by releasing subdermal implant etonogestrel (ENG) in women of reproductive age treated in the family planning consultation of a Venezuelan hospital. Methods: Comparative and applied research, with quasiexperimental, case-control, open label and prospective design, with an intentional sample of 60 women separated to receive the contraceptive implant (Implanon NXT®; cases) or a cooper intrauterine device (IUD) (Cooper T; controls) was carried out. Body weight and body mass index were evaluated before and after 12 months of contraceptive use; as well as demographic characteristics of users, side effects, and contraceptive effectiveness of each method. Results: After one year with the ENG implant, no significant variations were found with respect to initial measurements of body weight (61.21±8.30 vs. 61.23±9.50, p>0.5) and BMI (25.23±3.89 vs 25.26±4.30; p>0.05); on the contrary, to what was observed among IUD users where both body weight and BMI had a significant increase (P<0.05). Likewise, most users remained in the same weight range as when starting the method (p<0.001); while weight gain was greater among IUD users (1,530±2.04 vs. 3,700±3.02; p<0.05). Conclusions: The ENG implant does not produce an increase in body weight after 12 months of use, with minimal adverse effects and high contraceptive efficacy.

          Weight change at 12 months in users of three progestin-only contraceptive methods.

          Concerns about weight gain may influence contraceptive use. We compared the change in body weight over the first 12 months of use between women using the etonogestrel (ENG) implant, the levonorgestrel intrauterine system (LNG-IUS) or depot medroxyprogesterone acetate (DMPA) with women using the copper intrauterine device (IUD).

            Discontinuation rate and associated factors among contraceptive implant users in Kersa district, southwestern Ethiopia

            Background Subdermal contraceptive implant is the most widely used method of long-acting reversible contraception among Ethiopian women. Many, however, discontinue use early, which results in unwanted pregnancies and induced abortions and their associated complications. The aim of this study is to determine the rate of and reasons for discontinuation of the contraceptive implant among users in the Kersa district of southwestern Ethiopia. Methods A mixed-method study was carried out between March and April 2019 among 475 women who had been using the contraceptive implant between January 2015 and August 2016 in the Kersa district. Systematic random sampling was used for quantitative data collection and purposive sampling was used for qualitative data collection using 8 focus group discussion and 56 In-depth interviews. A binary logistic regression was carried out for bivariate and multivariable analyses. Results One hundred and ten (23.2 %) contraceptive implant users requested removal before 2.5 years of use. The main reasons for the discontinuation were side effects, followed by a desire for pregnancy or to switch to another contraceptive method and misconceptions. Implant discontinuation was associated with a lack of information prior to insertion on the effectiveness of modern contraception (adjusted odds ratio [OR] 2.0; 95 % confidence interval [CI] 1.13, 3.55), being served by a midwife or nurse (adjusted OR 1.8; 95 % CI 1.04, 3.23), and not being told to return to the health facility if any side effects were experienced (adjusted OR 1.8; 95 % CI 1.01, 3.19) (all p  < 0.05). Conclusions Almost a quarter of the study participants discontinued use of the contraceptive implant before the due date. Public health interventions should focus on providing adequate awareness for family planning users, trainings for the health care workers on effective counselling services, especially on side effect and misconceptions.

              Satisfaction, early removal, and side effects associated with long-acting reversible contraception.

              Although intrauterine devices (IUDs) and subdermal implants (SDI) are recommended as first-line contraception for the majority of women by the American College of Obstetrics and Gynecology, these methods of long-acting reversible contraception (LARC) are underutilized. Some concerns regarding their use include cost of placement, side effects, and perception of frequent early removal. This study evaluated satisfaction with LARC, frequency, and reasons behind early removal in a family medicine setting.
