“…This anticipation deserves attention, given that more than a quarter of the participants in this study had their first sexual intercourse until the age of fourteen. This result was also observed in a study that analyzed the recurrence of adolescent pregnancy in the state of Ceará, where the exchange of partners was associated with a risk condition for subsequent pregnancy, increasing the probability of a new pregnancy 40 by about 40%. Another study with adolescents from four Nordic countries found that the odds of reporting more than ten lifetime sexual partners were four times higher among women reporting early onset of sexual intercourse compared to those reporting age over 14 years on the occasion of the first intercourse 23 .…”

BackgroundThe UK has one of the highest rates of teenage pregnancies in Western Europe. One-fifth of these are repeat pregnancies. Unintended conceptions can cause substantial emotional, psychological and educational harm to teenagers, often with enduring implications for life chances. Babies of teenage mothers have increased mortality and are at a significantly increased risk of poverty, educational underachievement and unemployment later in life, with associated costs to society. It is important to identify effective, cost-effective and acceptable interventions.ObjectivesTo identify who is at the greatest risk of repeat unintended pregnancies; which interventions are effective and cost-effective; and what the barriers to and facilitators of the uptake of these interventions are.Data sourcesWe conducted a multistreamed, mixed-methods systematic review informed by service user and provider consultation to examine worldwide peer-reviewed evidence and UK-generated grey literature to find and evaluate interventions to reduce repeat unintended teenage pregnancies. We searched the following electronic databases: MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library (Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and the Health Technology Assessment Database), EMBASE (Excerpta Medicadatabase), British Nursing Index, Educational Resources Information Center, Sociological Abstracts, Applied Social Sciences Index and Abstracts, BiblioMap (the Evidence for Policy and Practice Information and Co-ordinating Centre register of health promotion and public health research), Social Sciences Citation Index (supported by Web of Knowledge), Research Papers in Economics, EconLit (American Economic Association’s electronic bibliography), OpenGrey, Scopus, Scirus, Social Care Online, National Research Register, National Institute for Health Research Clinical Research Network Portfolio and Index to THESES. Searches were conducted in May 2013 and updated in June 2014. In addition, we conducted a systematic search of Google (Google Inc., Mountain View, CA, USA) in January 2014. Database searches were guided by an advisory group of stakeholders.Review methodsTo address the topic’s complexities, we used a structured, innovative and iterative approach combining methods tailored to each evidence stream. Quantitative data (effectiveness, cost-effectiveness, risk factors and effect modifiers) were synthesised with reference to Cochrane guidelines for evaluating evidence on public health interventions. Qualitative evidence addressing facilitators of and barriers to the uptake of interventions, experience and acceptability of interventions was synthesised thematically. We applied the principles of realist synthesis to uncover theories and mechanisms underpinning interventions (what works, for whom and in what context). Finally, we conducted an overarching narrative of synthesis of evidence and gathered service user feedback.ResultsWe identified 8664 documents initially, and 816 in repeat searches. We filtered these to 12 randomised controlled trials (RCTs), four quasi-RCTs, 10 qualitative studies and 53 other quantitative studies published between 1996 and 2012. None of the RCTs was based in the UK. The RCTs evaluated an emergency contraception programme and psychosocial interventions. We found no evidence for effectiveness with regard to condom use, contraceptive use or rates of unprotected sex or use of birth control. Our primary outcome was repeat conception rate: the event rate was 132 of 308 (43%) in the intervention group versus 140 of 289 (48%) for the control goup, with a non-significant risk ratio (RR) of 0.92 [95% confidence interval (CI) 0.78 to 1.08]. Four studies reported subsequent birth rates: 29 of 237 (12%) events for the intervention arm versus 46 out of 224 (21%) for the control arm, with a RR of 0.60 (95% CI 0.39 to 0.93). Many repeat conceptions occurred in the context of poverty, low expectations and aspirations, and negligible opportunities. Service user feedback suggested that there were specific motivations for many repeat conceptions, for example to replace loss or to please a partner. Realist synthesis highlighted that context, motivation, planning for the future and letting young women take control with connectedness and tailoring provide a conceptual framework for future research.LimitationsIncluded studies rarely characterised adolescent pregnancy as intended or unintended, that is interventions to reduce repeat conceptions rarely addressed whether or not pregnancies were intended. Furthermore, interventions were often not clearly defined, had multiple aims and did not indicate which elements were intended to address which aims. Nearly all of the studies were conducted in the USA and focused largely on African American or Hispanic and Latina American populations.ConclusionsWe found no evidence to indicate that existing interventions to reduce repeat teenage pregnancy were effective; however, subsequent births were reduced by home-based interventions. Qualitative and realist evidence helped to explain gaps in intervention design that should be addressed. More theory-based, rigorously evaluated programmes need to be developed to reduce repeat teenage pregnancy in the UK.Study registrationThis study is registered as PROSPERO CRD42012003168.

“…Sin embargo, en las encuestas realizadas con adolescentes no embarazadas, predominan las solteras. Según autores (16,17) la presión social debido al embarazo favorece la formalización de una unión, lo que se refleja, de manera formal o informal, en el estado civil. Es necesario hacer hincapié en que tanto la unión consensual como los matrimonios son eventos importantes en la trayectoria afectivo-sexual del individuo y representan un marco en el proceso de autonomía de los adolescentes con relación a su familia de origen, especialmente cuando no existen otros recursos/proyectos de vida (2).…”

RESUMENSe trata de un estudio transversal con el objetivo de analizar la percepción de riesgo de la infección por el VIH entre adolescentes embarazadas en el Distrito Federal, Brasil. Fueron entrevistadas 336 adolescentes gestantes de edades comprendidas entre 13 y 19 años, atendidas en el sistema público de salud del Distrito Federal, entre abril y noviembre de 2009. El Comité de Ética aprobó el estudio (Parecer N o 33/2009). En el análisis estadístico se utilizó el test χ 2 . La mayoría de las entrevistadas estaban casadas/unión estable, con una iniciación sexual media de 14,9 años de edad, hicieron uso del preservativo en la primera y última relación sexual un 64,0% y un 14,9% respectivamente. El 33,3% de las adolescentes eran conscientes del riesgo de infección por VIH al quedarse embarazadas, recayendo la mayor percepción de riesgo (p=0,014) entre las que tuvieron más de un compañero sexual. No se observaron diferencias estadísticas entre la percepción de riesgo y las variables edad, estado civil, cohabitación, escolaridad, religión o frecuencia de uso del preservativo. En conclusión, fue baja la percepción de riesgo de infección por VIH de las adolescentes embarazadas del Distrito Federal. ABSTRACTThis is a transversal study with the aim of analyzing the perception of risk of HIV infection among pregnant adolescents in the Federal District of Brazil. 336 pregnant adolescents between the ages of 13 and 19 who received prenatal care from the public hospital system between April and November 2009 were interviewed. The study was approved by the ethics committee (Opinion No. 33/2009). The Pearson χ 2 test was used in the statistical analysis. Most interviewed were married/stable union with sexual initiation average 14.9 years old, made use of condoms in the first and last sexual union 64.0% and 14.9% respectively. Around 33.3% of the adolescents perceived the risk of HIV infection upon becoming pregnant with the highest perception of risk (p=0.014) among those who had had more than one sexual partner. Statistical differences were not observed with the variables: age, marital status, cohabitation, educational level, religion or frequency of condom use. In conclusion, the perception of risk among pregnant adolescents in the Federal District was low.
