Análisis de causas o motivos que fragmentan el sueño y los trastornos del sue-ño, en mujeres embarazadas y no embarazadas.

INTRODUCTION: During pregnancy, sleep undergoes important changes. The objective was to assess the causes or reasons that fragment sleep and sleep disorders in different women and trimesters of pregnancy, comparing them with those of non-pregnant women (NPW). METHODS: Cross-sectional study. Anonymous surveys were used to evaluate reasons that fragment sleep and specific questionnaires to evaluate sleep disorders. RESULTS: Pregnant Women (PW)= 320. 1st Trimester of pregnancy (T): n = 106, 2nd. T: n = 104, 3rd T: n = 110. MNE: n = 304. Most frequent reasons that fragmented sleep, statistically significant in PW and were: need to urinate, uncomfortable position, not being able to rotate in bed. As sleep disorders we find: nightmares 44 vs 4.9%; snoring with pauses: 31 vs 3%. CONCLUSION: We found that in the PW studied, most of the causes or reasons analyzed fragmented sleep; they had more sleep disorders such as nightmares, respiratory disorders and periodic leg movements, in that order, compared to the NPW who in turn, presented insomnia, excessive sleepiness and bruxism.
