title: PP147. Prevalence of hypertensive syndromes according to pregnancy age.
abstract: BACKGROUND
  The decision of a woman to get pregnant at later age of her reproductive cycle has be a phenomenon around the world. Epidemiology data show frequent increase of clinical complications in direct proportion in advanced age motherhood, hypertensive disturbances being more prevalent.
  
  
  OBJECTIVE
  Analyse the prevalence of hypertensive syndromes in pre-determined age groups at Hospital Guilherme Álvaro in Santos, São Paulo, Brazil showing the different segments in each one.
  
  
  METHODS
  From data collected in the outpatient department of Hospital Guilherme Álvaro of High Risk Pre-natal between 04/06/2008 and 30/05/2011, a prevalence transversal study was carried out where data were obtained from 628 patients aged between 16 and 46years. Procedures of homogeny analysts were set out, always collecting data such as age and disorder for high risk gestation. According to age, patients were divided into groups: precocious (up to 19years old), middle age (between 20 and 34) and late pregnancies (over 35).
  
  
  RESULTS
  In the precocious pregnancies, clinical illnesses/no hypertension (31%) were observed in first place, 25% (8) twin pregnancy in second place, 19% (6) showed hypertensive disturbances. Concerning pregnancies between 20 and 34years old, 36% (144 patients) showed hypertensive syndromes, 23% (92 patients) showed endocrine disturbances, 22% (90 patients) showed clinical illnesses/no hypertension, and 9% twin pregnancy. Regarding late pregnancies, the most frequent disturbance was isolated hypertensive syndromes: 44% (88 patients) in first place, only endocrine disturbances, 24% (47 patients) in second place followed by association between hypertensive syndromes and endocrinopathy with 13% (26 patients).
  
  
  CONCLUSIONS
  About precocious pregnancies, greater prevalence showed clinical illnesses/no hypertension, whereas middle age and late pregnancies showed greater hypertensive syndrome prevalence, results, which are compatible with other studies, have been observed that due to advance of age, hypertensive syndromes are more frequent. For late pregnancies, the prevalence of clinical illnesses/no hypertension was a lower percentage regarding the other two groups: precocious pregnancies (31%=10 women), middle age pregnancies (22%=90 women), and late pregnancies (2%=7 women). Considering the fact that the occurrence of pregnancy is more and more late in life, it can be concluded that the professionals must be prepared to attend pregnancies on women with hypertensive disturbances and their eventual complications.
