To study the prevalence of external sleep disturbances and their influence in sleep quality.
Transversal descriptive study based on personal self-applied interview and the application of the Pittsburg Sleep Quality Index (PSQI) in 1053 persons selected among the over 18 year old population of the city of Valladolid between September 1997 and August 1998 in relation to different sociodemographics variables, life habits and psychiatric pathologies (anxiety and depression evaluated by Golberg Scale).
Worsening of life quality and sleep efficiency was significantly associated to external disturbances such as coughing, going to the bathroom and nocturnal awakening and, less significantly, to pain sensation, having nightmares, dysthermic sensations and difficulty to breathing. Sleep external disturbances did not affect daytime activity but was associated to an increased hypnotic drug taking.
Sleep external disturbances are one of the most relevant and unknown variables associated to a decrease in sleep quality and, consequently, in life quality.
研究外部睡眠干扰的患病率及其对睡眠质量的影响。
基于个人自我访谈以及对1053人应用匹兹堡睡眠质量指数（PSQI）的横向描述性研究。这些人于1997年9月至1998年8月在巴利亚多利德市18岁以上人群中选取，涉及不同的社会人口统计学变量、生活习惯和精神疾病（通过戈德堡量表评估焦虑和抑郁）。
生活质量和睡眠效率的恶化与咳嗽、上厕所和夜间觉醒等外部干扰显著相关，与疼痛感觉、做噩梦、体温异常感觉和呼吸困难的相关性较小。睡眠外部干扰不影响白天活动，但与催眠药物服用增加有关。
睡眠外部干扰是与睡眠质量下降以及生活质量下降相关的最相关且未知的变量之一。
