Evaluación de un programa de educación sexual sobre conocimientos y conductas sexuales en embarazadasEvaluation of a sexual education program on knowledge and sexual behaviour in pregnant. RESUMENObjetivo: Evaluar el nivel de conocimientos de la sexualidad en la gestación previos y posteriores a un programa formativo implementado por un grupo de gestantes en el segundo y tercer trimestre.Material y método: diseño cuasi-experimental pre-post test de un único grupo. Participaron 40 mujeres grávidas de bajo riesgo que se encontraban en su segundo y tercer trimestre de gestación. Todas eran de raza blanca. El 85% de las gestantes comprendían una edad entre 20 y 35 años, un 60% eran primigestas.Resultados: al 60% de las mujeres del estudio les ha afectado el embarazo a su vida sexual. El trimestre que ellas creen que pueden disfrutar más del sexo, en un primer cuestionario el 62.5% contestaron que en el segundo, después de implantar el programa, el 95% dieron esa respuesta. Entre las diferentes técnicas sexuales que existen, el 87.5% la conocían en un principio, después de realizar nuestro programa el porcentaje aumentó a un 97.4%. En cuanto a los beneficios de los ejercicios de Kegel, en un primer cuestionario tan sólo el 25% sabían la respuesta correcta, mientras que más tarde aumentó a un 85% y su práctica era realizada un 12.5% antes de la intervención, y después un 40%.Discusión-Conclusión: después de aplicar nuestro programa específico se notaron algunas mejoras en el nivel de conocimientos y actitudes sexuales aunque debido probablemente a la pequeña muestra utilizada no se han encontrado resultados estadísticamente significativos salvo en una variable (práctica de Kegel). ABSTRACTObjective: Evaluate the level of knowledge of sexuality in pregnancy before and after a training program implemented by a group of pregnant women in the second and third trimesters. Materials and methods:A quasi-experimental pre-post test single group. A total of 40 pregnant women at low risk who were in their second and third trimester were included. Regarding the ethnical group all Enfermería Global Nº 28 Octubre 2012 Página 454women were white. The 85% of pregnant women included had an age between 20 and 35 years and for the 60% it was their first pregnancy.Results: 60% of women have altered her sex life. The initially believed that the most suitable month to enjoy sex live more was on the second trimester, as shown on the first questionnaire (62.5%). After implementing the program, these results increased up to the 95%. Regarding the different sexual techniques, 87.5% knew them at first, after participating in our program this percentage increased to 97.4%. In relation to the benefits of Kegel exercises, in the first questionnaire only 25% knew the correct answer, while after the program increased to 85%. Its practice increased to 12.5% before the intervention, and then a 40% of pregnant women said they knew it and practiced it.Discussion-Conclusion: after applying our specific program noted some improvements in the level of knowl...
Preterm delivery affects about one tenth of human births and is associated with an increased perinatal morbimortality as well as with remarkable costs. Even if there are a number of predictors and markers of preterm delivery, none of them has a high accuracy. In order to find quantitative indicators of the immediacy of labor, 142 cardiotocographies (CTG) recorded from women consulting because of suspected threatened premature delivery with gestational ages comprehended between 24 and 35 weeks were collected and analyzed. These 142 samples were divided into two groups: the delayed labor group (n = 75), formed by the women who delivered more than seven days after the tocography was performed, and the anticipated labor group (n = 67), which corresponded to the women whose labor took place during the seven days following the recording. As a means of finding significant differences between the two groups, some key informational properties were analyzed by applying nonlinear techniques on the tocography recordings. Both the regularity and the persistence levels of the delayed labor group, which were measured by Approximate Entropy (ApEn) and Generalized Hurst Exponent (GHE) respectively, were found to be significantly different from the anticipated labor group. As delivery approached, the values of ApEn tended to increase while the values of GHE tended to decrease, suggesting that these two methods are sensitive to labor immediacy. On this paper, for the first time, we have been able to estimate childbirth immediacy by applying nonlinear methods on tocographies. We propose the use of the techniques herein described as new quantitative diagnosis tools for premature birth that significantly improve the current protocols for preterm labor prediction worldwide.
Due to the significant increase in predictive parameters and the reduction of incorrectly classified cases when LEIOA was combined with the medical variables, we conclude that it could be a very useful tool to improve the estimation of the immediacy of preterm delivery.
