This work aims to investigate whether there are reports in the literature about the role of the recruiter's characteristics on participation in research projects focused on gestational women.
A bibliographic search was performed in SCIELO, Redalyc, Latindex, MEDLINE (through PubMed), SCOPUS and Web of Knowledge of articles published in English or Spanish with the search terms: Participation in research, informed consent, motivation and influence, reasons to participate in clinical research, recruitment characteristics.
We conclude that sociodemographic characteristics and perception of risk are important in the decision- making process of pregnant women to decide a positive answer when being asked to participate in a clinical trial.
RESUMENIntroducción: la preeclampsia es aún uno de los mayores problemas obstétricos en países en vías de desarrollo. Objetivo: identificar los principales factores de riesgo para desarrollar preeclampsia en mujeres mexiquenses atendidas en el Hospital Materno Perinatal "Mónica Pretelini Sáenz". Material y métodos: estudio de casos y controles, se incluyeron dos grupos, el grupo A casos (n=138) y el grupo B controles (n=276) con relación caso-control de 1:2. Los criterios de definición para los casos fueron: mujeres con diagnóstico inicial de preeclampsia y que cuenten con las siguientes mediciones: Tensión Arterial Sistólica (TAS)≥140 ó Tensión Arterial Diastólica (TAD)≥90 mmHg más una de las siguientes: concentración de proteínas en orina de 24 h ≥300 ó Proteinuria ≥++. El grupo de controles quedó conformado por mujeres que acudieron al hospital para atención del embarazo sin preeclampsia. Resultados: la media de edad fue de 27.5±8.0 para los casos (grupo A) y 25.3±6.7 para los controles (grupo B) (P<0.01). El tener 1 o más óbitos (P<0.045), las cifras iniciales y finales de TAS y TAD, el índice de masa corporal pregestacional (IMCPG), el peso al final del embarazo, y la hipertensión arterial sistémica crónica (P<0.01) así como el haber padecido preeclampsia en algún embarazo previo fueron estadísticamente significativo (P<0.01) para tener preeclampsia. Conclusiones: en nuestra población, además de los factores de riesgo tradicionales para preeclampsia se agrega el antecedente de óbitos como otro factor de riesgo para padecer preeclampsia.Palabras clave: factores de riesgo, óbito, preeclampsia.
ABSTRACTIntroduction: preeclampsia is still a major obstetric problem in developing countries.Objective: To identify the main risk factors to develop preeclampsia in women from the State of Mexico attended at the Maternal Perinatal Hospital "Mónica Pretelini Sáenz". Materials and methods: in this casecontrol study, two groups were included, group A patients (n = 138) and B controls (n = 276) with a case-control ratio of 1: 2. The criteria for defining cases were women initially diagnosed with preeclampsia and who had the following measurements: Systolic Blood Pressure (SBP) ≥140 or diastolic blood pressure (DBP) ≥90 mmHg plus one of the following: ≥300 protein concentration in a 24-h urine sample or proteinuria ≥ ++. The control group was made up of women attended __________________________________________________________________________________________________ 1.
