Epidemiology – Coursera Note

Week 1: 流行病学的定义 Epidemiology: 流行病学,研究在特定群体中的健康相关的事件的分布与决定因素,以及健康问题的控制。 Bo: 健康相关:它可以是正面的或者是负面的? Epi – on or upon; Demos – people; Logos: the study of. https://www.coursera.org/learn/epidemiology-tools/lecture/0Fpnv/definition-of-epidemiology 由上图可知,公共健康管理系统的目标是确保人的寿命以及生活质量。 影响国民健康(生理、心理)的因素包括 日常行为(抽烟,饮食,性生活)30%; 医疗设施(看病是否困难,医疗设施的质量)20%; 社会、经济因素(教育,就业率,收入,家庭社会保障,社区安全)40% 物理环境(空气,水质量,住房公共交通)10% Bo: 医院是否发达,看病难看病贵只占国民健康的20%,比例不大,但却是影响最直接的,容易上新闻,上政策。更深远的影响国民健康的因素,是社会和经济因素,比如教育、就业、收入等,是间接的。启发:多去思考思考那些长期的,影响更大的因素。用刀杀人,和按动核按钮杀人,都是杀人。后者间接,但影响更大。扶贫,给钱最直接,但帮助周期最短;提供就业岗位间接一些,但是稍微可以持久;提供教育,是目前我能想到的最长远的方式。 流行病学的历史 公元前400,希波克拉提斯(hippocrates)(医学之父),提出空气、水、环境以及宿主的因素会导致疾病。被视为流行病学的开端。 事例回顾:十九世纪中期的英国泰晤士河,垃圾,动物尸体丢进泰晤士河,人们的饮水也从里面而来。霍乱(Cholera)盛行。 Snow(人名),研究霍乱患病地图与水井的分布关系。
