研究目标：确定撒哈拉以南非洲未充分研究的老年人群中失眠的发病率和危险因素。地点：尼日利亚西南部和中北部的八个连续的以约鲁巴语为主的州，约占全国人口的 22%。参与者：1307 名社区居民，年龄在 65 岁及以上。测量：使用综合国际诊断访谈版本进行面对面评估2007年和12个月后的2008年进行了CIDI.3，以确定事件性和持续性失眠（定义为综合征或症状）的发生率和危险因素。结果：2008年12个月时失眠综合征的发生率为7.97%（95% CI，6.60-9.60），而失眠症状的发生率为25.68% （22.68-28.66）。女性出现综合症和症状的风险均较高。在基线时有失眠症状或综合征的人中，47.36% (95% CI 43.07-51.68) 一年后仍存在失眠症状或综合征。经济状况的下降与失眠发生率的增加有关。基线时患有慢性疾病的人新发失眠的风险增加。与体重指数（BMI）最低（< 18.5）的人相比，BMI较高的人持续失眠的风险较高，而肥胖范围（>=30）的人则有4倍的风险。 结论：老年人群失眠的发生率较高且长期存在。患有慢性疾病的人特别容易出现新发和持续失眠的风险。
Study Objectives: To determine the incidence and risk factors for insomnia among an under-studied population of elderly persons in Sub-Saharan Africa.Setting: Eight contiguous predominantly Yoruba-speaking states in south-west and north-central Nigeria representing about 22% of the national population.Participants: 1307 elderly community-dwelling persons, aged 65 years and older.Measurements: Face-to-face assessment with the Composite International Diagnostic Interview, version 3 (CIDI.3) in 2007 and 12 months later in 2008 to determine the occurrence and risk factors of incident and persistent insomnia, defined as syndrome or symptom.Results: The incidence of insomnia syndrome in 2008 at 12 months was 7.97% (95% CI, 6.60-9.60), while that of insomnia symptom was 25.68% (22.68-28.66). Females were at elevated risk for both syndrome and symptom. Among persons with insomnia symptom or syndrome at the baseline, 47.36% (95% CI 43.07-51.68) continued to have it one year later. Decreasing economic status was associated with increasing incidence of insomnia. Persons with chronic medical conditions at baseline were at increased risk for new onset of insomnia. Compared to persons with the lowest body mass index (BMI) (< 18.5), those with higher BMI were at elevated risk for persistence of their insomnia, with those in the obese range (>= 30) having a 4-fold risk.Conclusions: There is a high incidence and chronicity of insomnia in this elderly population. Persons with chronic health conditions are particularly at risk of new onset as well as persistence of insomnia.
