CONTROL ID: 2746919 TITLE: LUMBO PELVIC PAIN DURING PREGNANCY AND EVOLUTION AFTER DELIVERY. OBSERVATIONAL AND DESCRIPTIVE STUDY AUTHORS (FIRST NAME INITIAL LAST NAME): M. Venegas1 , D. Cohen Szobel1 , B. Fuentes1 INSTITUTIONS (ALL): 1. Centro Especialidades Piso Pelviano, Clinica Las Condes, Santiago, Region Metropolitana, Chile. PRESENTATION TYPE: Oral or Poster CURRENT SUB-CATEGORY: Epidemiology/Health care system CURRENT CATEGORY: Population studies ABSTRACT BODY: Objectives: The objective of this study was to determine the prevalence of lumbo pelvic pain (LPP) during pregnancy and the presence of it after delivery. We evaluated the disability degree of this group during these two periods. We also investigated the presence of risk factors that could mark an influence during these periods. Methods: This was an observational and descriptive study. We recruited 81 women during their third trimester of pregnancy between January 2014 and December 2015 in a consecutive non-probabilistic way. This group signed a written consent approved by the ethics committee of our institution and completed a self- administered interview. They where contacted by email 3 months after their delivery so as to answer the same self- administered interview. Those who had LPP also completed the Oswestry test (in both periods) so as to determine the disability degree in their daily life. In this interview we searched for those risk factors that could influence in LPP such as: delivery type, number of deliveries, age and body mass index. We also analyzed the pain characteristics and the association with other pelvic disfunctions. The statistics analysis was performed with the Fisher exact test for categorical variables with a unilateral hypothesis. For ordinal and continuous variables the Wilcoxon test was used so as to compare the median in paired variables. A p-value < 0.025 was considered statistically significant. Results: 66 of 81 women of the studied group (81,48%) had LPP during pregnancy. It was more prevalent during the third trimester (72,84%). 21 women (25,93%) persisted with LPP three months after delivery. There is an existing association between LPP and disability degree, during pregnancy and post delivery period, which was statistically significant (p<0,000). The other risk factors analyzed such us age, delivery type, number of deliveries and body mass index did not show any statistics significance. Conclusions: We can conclude that LPP is highly prevalent during pregnancy. In our studied group it was higher when compared with international reports. LPP remains after three months of delivery in quite a large number of patients, producing disability in this period.
