Development of a Multidimensional Predictive Model of Dystocic Labor. Association of Physical Condition and Psychosocial Factors With the Birth Process and Breastfeeding Success. (MPM-PD)

Development of a Multidimensional Predictive Model of Dystocic Labor (MPM-PD): Pilot Study on the Association of Physical Condition and Psychosocial Factors With the Completion of Labor and the Success of Breastfeeding.

The goal of this observational study is to learn how a pregnant woman's physical fitness and emotional well-being can help predict the type of birth she will have (such as a natural vaginal birth versus a cesarean section or a birth requiring medical assistance). The study focuses on pregnant women in their third trimester (after 28 weeks of pregnancy).

The main questions the study aims to answer are:

  • Can simple tests of physical strength and questions about emotions (like fear of childbirth) help health professionals predict if a birth might have complications or lack of progress?
  • Do a woman's physical activity and confidence levels during pregnancy affect her ability to successfully breastfeed her baby for up to 6 months?

Participants will be asked to:

  • Perform two simple physical tests during a clinic visit: a hand-grip test (dynamometry test) and a test to see how many times they can stand up from a chair in 30 seconds (Chair Stand Test, CST).
  • Complete surveys about their daily physical activity (PPAQ-S), their feelings and fears regarding childbirth (WDEQ-A), and how confident they feel about handling the final stage of birth and the pushing phase (CBSEI-16).
  • Answer brief follow-up phone calls one month and six months after the birth to talk about how breastfeeding is going.

Studiebefolkning

The study population consists of pregnant women receiving prenatal care at the Hospital Universitari de Tortosa Verge de la Cinta (HUTVC).

The sample includes healthy volunteers in their third trimester of pregnancy (>28 weeks of gestation) with low-to-moderate obstetric risk. The population reflects a diverse group of expectant mothers who are able to perform simple physical functional tests and are interested in contributing to research on birth outcomes and breastfeeding. Participants are selected during their routine third-trimester prenatal visit at the HUTVC through non-probabilistic consecutive sampling until the required sample size of 420 participants is reached.
