马尼托巴炎症性肠病队列研究
2017年8月23日 更新者：University of Manitoba
马尼托巴炎症性肠病 (IBD) 队列研究参与者来自基于人群的研究登记处。
该队列由 388 名近期 IBD 发作的成年参与者组成，他们在 2002 年至 2003 年完成了基线调查和访谈。 每 6 个月对参与者进行一次调查，每年进行一次访谈。 通过图表审查来验证诊断和疾病类型。
研究概览
详细说明
2002 年启动的曼尼托巴炎症性肠病 (IBD) 队列研究是对患有 IBD 的成人进行的研究，这些患者通过年度临床访谈和半年一次的调查进行了前瞻性追踪。 参与者来自一个经过验证的基于人群的研究登记处，该登记处使用 IBD 的行政定义从 Manitoba Health 的综合健康数据库中识别和招募个人，Manitoba Health 是为该省所有居民提供医疗保健的单一保险公司。
该队列由 388 名近期 IBD 发作的成年参与者组成，他们在 2002 年至 2003 年完成了基线调查和访谈。 每 6 个月对参与者进行一次调查，每年进行一次访谈。 通过图表审查来验证诊断和疾病类型。 已经证明队列代表了整个省级 IBD 人口，具有可比的年龄分布、性别分布、病程和农村/城市居住地。

研究人群
完整的数据是从 388 个人的第一次接触中获得的。 在纵向队列研究的前两年，有适度的流失，到 24 个月接触时，仍有 353 名受访者继续参与。
每年都会对参与人员进行面对面访谈和半年一次的邮寄调查。 到 5 年结束时，仍有 353 人参与（每年损失 1.8%）。
参与者年龄为 18-83 岁，60% 为女性。 大约三分之二居住在温尼伯，其余居住在整个马尼托巴省，包括 Brandon、Dauphin、Swan River、Flin Flon、Thompson、Winkler 和 Steinbach。 一些受试者住在加拿大其他地方，但仍保持参与。
直到 2016 年为止跟踪了 270 名受试者

IBD-自我效能 (SE) 是由 Keefer 等人开发的 29 项量表。 (1) 基于患者访谈，验证其他疾病的自我效能测量。
该仪器评估管理各种疾病相关“任务”的信心水平，项目得分从 1（完全没有）到 10（完全），得分越高反映疾病自我管理效果越好。
项目在概念上分为 4 个分量表，反映了 IBD 患者认为重要的领域 [1] 管理压力和情绪（样本项目：避免感到悲伤；做一些事情来减轻压力）； [2] 管理医疗（样本项目：按指示时间服药；与医生解决差异）； [3] 管理症状和疾病（示例项目：防止腹泻/紧迫感干扰；减少疲劳）； [4] 维持缓解（样本项目：进行自我保健；保持幸福感）。
