前言：尽管失眠的患病率很高，但关于其发病率和危险因素的信息却很少。这项研究估计了失眠的发病率，并对一组睡眠良好的人进行了为期一年的随访，检查了潜在的危险因素。方法.参与者是464名睡眠良好的人，他们在一年内完成了3次邮政评估（即，基线、6个月和12个月）。问卷评估了睡眠、心理和个性变量、压力性生活事件和应对技能以及与健康相关的生活质量。参与者被分为3个亚组：（a）睡眠良好者（即，在3次评估中保持良好睡眠的参与者），（B）失眠症状事件病例（即，在6个月或12个月随访时出现失眠症状），以及（c）失眠综合征事件病例（即，结果：1年内失眠症状发生率为30.7%，失眠综合征发生率为7.4%。这些比率下降到28.8%和3.9%的那些没有以前的生活失眠发作。与良好睡眠者和失眠症状事件病例相比，失眠综合征事件病例表现出对失眠的病前心理脆弱性，其特征是基线时较高的抑郁和焦虑症状、较低的外向性、较高的唤醒性和较差的自评心理健康。他们还表现出更高程度的身体疼痛和更差的总体健康状况。五个变量与一个新的发作的失眠syndrome：以前发作的失眠，积极的失眠家族史，较高的arousability易感性，较差的自我评价的一般健康状况，和较高的身体pains.Conclusion：一年的失眠发病率是非常高的，一些心理和健康因素与新发失眠。对这些诱发因素的性质的进一步了解将有助于指导有效的公共卫生预防和干预计划的发展，以促进更好的睡眠质量。
Introduction: Despite the high prevalence of insomnia, there is little information about its incidence and risk factors. This study estimated the incidence of insomnia and examined potential risk factors in a cohort of good sleepers followed over a one-year period. Methods. Participants were 464 good sleepers who completed 3 postal evaluations over a one-year period (i.e., baseline, 6 months, and 12 months). Questionnaires assessed sleep, psychological and personality variables, stressful life events and coping skills, and health-related quality of life. Participants were categorized into 3 subgroups: (a) good sleepers (i.e., participants who remained good sleepers at the 3 assessments), (b) insomnia symptoms incident cases (i.e., developed insomnia symptoms either at 6- or 12-month follow-up), and (c) insomnia syndrome incident cases (i.e., developed an insomnia syndrome either at 6- or 12- month follow-up).Results: One-year incidence rates were 30.7% for insomnia symptoms and 7.4% for insomnia syndrome. These rates decreased to 28.8% and 3.9% for those without prior lifetime episode of insomnia. Compared to good sleepers and insomnia symptoms incident cases, insomnia syndrome incident cases presented a premorbid psychological vulnerability to insomnia, characterized by higher depressive and anxiety symptoms, lower extraversion, higher arousability, and poorer self-rated mental health at baseline. They also presented a higher level of bodily pain and a poorer general health. Five variables were associated with a new onset of an insomnia syndrome: previous episode of insomnia, positive family history of insomnia, higher arousability predisposition, poorer self-rated general health, and higher bodily pain.Conclusion: The one-year insomnia incidence rate was very high and several psychological and health factors were associated with new onset insomnia. Improved knowledge about the nature of these predisposing factors would be helpful to guide the development of effective public health prevention and intervention programs to promote better sleep quality.
