This research project aims to initiate a prevention programme for pregnant women from 28 weeks, who attend their prenatal check-up at the Guano Health Centre in the period April 2012-2013. This is a descriptive, prospective, cross-sectional study. The obstetric psychoprophylaxis programme will include: Preparation for childbirth; obstetric physiotherapy exercise routines; body and mental relaxation; breathing techniques; advice on nutrition, breastfeeding and newborn care; care and recommendations for a healthy pregnancy, with the aim of increasing the number of prenatal check-ups in pregnant women and reducing obstetric complications triggered by ignorance of the physiological changes of pregnancy.
