小呼吸道功能障碍 (SAD) 在健康的中国成年人中大约在55岁左右开始. 年龄是一个关键的预测因素,身体质量指数和性别也会影响这一群体的SAD发病.
科学领域:
- 肺部医学 肺部医学
- 衰老研究研究 衰老研究
- 呼吸系统健康 呼吸系统健康
背景情况:
- 小气道功能自然会随着年龄的增长而下降.
- 在健康的中国人中,小呼吸道功能障碍 (SAD) 的确切发病年龄尚不清楚.
- 这项研究解决了在特定的人群中理解SAD启动的差距.
研究的目的:
- 确定小呼吸道功能障碍 (SAD) 在健康的中国成年人中开始时的年代.
- 在这个人群中确定SAD的预测因素.
- 为确定SAD发病的年龄值.
主要方法:
- 对462名健康成年人的回顾性,横截面,多中心分析.
- 标准的螺旋计和问卷的填写.
- 接收器下面的区域运行特征曲线 (AUC) 用于确定SAD发病年龄;用于预测因子识别的单变量和多变量分析.
主要成果:
- 在55岁及以上的健康人群中观察到小呼吸道功能障碍 (SAD).
- 年龄是SAD的重要独立预测因素 (OR,1.107;P < 0.001).
- 当调整为体重指数和性别 (AUC=0.790) 时,SAD年龄的预测值 (AUC=0.771) 得到了改善.
结论:
- 该研究确定了健康的中国人群中小呼吸道功能障碍 (SAD) 的关键预测因素,考虑了环境暴露.
