Distúrbios do sono na gravidez

CONTEXT: The precise function of sleep in animals and human beings is still unknown, and any sort of physical, social or psychological variation may change the normal sleep-wake cycle. PURPOSE: This research aims is to determine the sleep disorders (SD) for each of the three trimesters of the pregnancy comparing them to the pre-pregnancy state (PG). METHOD: SD were investigated in three hundred pregnant women 11- to 40-years-old through with a brief clinical interview based on directed questions. One hundred pregnant women were considered for each trimester. RESULTS: The rate of pregnant women with insomnia increased by 23% in the 2nd trimester (p< 0.005); the rate for excessive daytime sleepiness (EDS) by 15% in the 1st trimester (p<0.003), 55% in the 2nd trimester (p<0.001) and by 14% in the 3rd trimester (p<0.002); the rate for mild sleepiness increased by 33% in the 2nd trimester (p<0.002) and by 48% in the 3rd trimester (p<0.001); the rate for specific awakenings increased by 63% in the 1st trimester, by 80% in the 2nd trimester and by 84% in the 3rd trimester (p<0.001). CONCLUSION: SD were more frequent during pregnancy comparatively to PG state, mostly at the expenses of EDS and specific awakenings.INTRODUÇÃO: A função exata do sono em animais e seres humanos ainda é desconhecida e qualquer variação física, social ou psíquica pode alterar o ciclo normal de sono e vigília. OBJETIVO: O objetivo desta pesquisa é detectar os principais distúrbios do sono (DS) nos três trimestres da gravidez comparando-os ao estado pré-gestacional (PG). MÉTODO: Os DS foram investigados em 300 gestantes com idades variando de 11 a 40 anos, através de breve entrevista com questões dirigidas. Foram incluídas 100 gestantes para cada trimestre. RESULTADOS: A proporção de grávidas com insônia aumentou 23% no 2º trimestre (p<0,005); a de sonolência intensa 15% no 1º trimestre (p<0,003), 55% no 2º (p<0,001) e 14% no 3º (p<0,002); a de sonolência leve 33% no 2º trimestre (p<0,002) e 48% no 3º (p<0,001); a de despertares específicos 63% no 1º trimestre, 80% no 2º e 84% no 3º (p<0,001). CONCLUSÃO: DS foram mais freqüentes durante a gravidez comparativamente ao PG, principalmente às custas de sonolência intensa e despertares específicos.Federal University of São Paulo Department of Neurology Sleep Disorders CenterFederal University of São Paulo Department of Internal MedicineFederal University of São Paulo Department of ObstetricianUNIFESP, Department of Neurology Sleep Disorders CenterUNIFESP, Department of Internal MedicineUNIFESP, Department of ObstetricianSciEL

Características de personalidade em uma amostra de pacientes com insônia psicofisiológica

The personality is the way people express themselves inside the environment they live. Sleep, quality or quantity, is a way of this physical and psychological expression of well being. Psychological factors, associated with psychophysiological insomnia (PPI) suggest an exaggerated perception of the difficulties to fall asleep. Worries, anxiety and the fear of not sleeping produce a bad sleep quality or sleep misperception. This study aims to identify personality features associated with PPI throughout Rorschach test (RT). Method: We studied 32 patients with PPI (22 women), between 29 and 75 years old. We excluded patients with other sleeping or psychiatric disorders. We analysed the data from PPI patients submitted to the RT and we compared our results with the standard data. Results: We noticed a significant increase in global answers and a significant decrease in detailed answers; a trend of a low number of answers; great number of shape and animal answers, especially for women. Conclusion: The features of the PPI patient's personality were daily problems insecure and the incapability to avoid or remove them from their thought, making bedtime a time for worries to appear again and motivate insomnia.Univ Fed Sao Paulo, Dept Neurol, Ctr Clin & Sci Sleep, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Emergency Med, Ctr Clin & Sci Sleep, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Neurol, Ctr Clin & Sci Sleep, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Emergency Med, Ctr Clin & Sci Sleep, Sao Paulo, BrazilWeb of Scienc
