Title: Assessment of the Effectiveness of a Program of Preparation to Pregnancy and Delivery
Brief Summary: Introduction: randomized studies on programs implemented during pre-natal care that offer information and physical activities preparing pregnant women for delivery are scarce in the scientific literature. Objective: to evaluate the effectively of the Program for Preparation of Pregnant Women for Delivery on the prevention of physical and psychological difficulties and problems during pregnancy and delivery in nulliparous women participating in the program. Subjects and methods: a randomized clinical single blind trial will be conducted with 192 pregnant nulliparous women allocated to participate or not of the program activities. The women allocated to the study group will participate of physical and educational activities at each pre-natal consultation and will receive orientation on the exercises they will perform at their home. Participants of the non-interventional group will follow the habitual routine care at the service. Participants will be selected among nulliparous low risk pregnant women aged between 16 and 40 years old after the 20th week of gestation. Data analysis: will be performing by intention to treat. For the continues variables the t-Student or Wilcoxon test will be performing; for the categorical variables the tests x² or Fisher, and the risk estimate will be estimated using a Relative Risk with 95% CI. ANOVA will be use for measures between the groups and along time, and correlation tests for anxiety and physical activity with gestational and perinatal variables.
