重庆市学龄前儿童蛲虫感染率的logistic回归分析

Logistic Regression Analysis on Infection Rate of Enterobius Vermicularis of Preschool Children in Chongqing City

目的了解重庆市不同地区学龄前儿童的蛲虫感染现状及相关影响因素,为今后蛲虫防治提供科学依据。方法选择重庆市城区和农村各1个区县作为调查点,每个调查点抽取5个乡镇,每个乡镇随机抽取1个幼儿园。采用透明胶纸肛拭法,定性检查蛲虫卵。同时对受检对象及其家庭的基本情况、卫生习惯、学校生活环境等进行问卷调查。结果重庆市学龄前儿童蛲虫感染率为7.10%,单因素结果显示农村、5～6岁组、父母亲外出打工、饭前和便后间断洗手、干扫教室地面、半托的儿童蛲虫感染率较高。经多因素非条件logistic回归分析显示,影响重庆市学龄前儿童蛲虫感染的因素有年龄、不同地区、母亲职业、饭前洗手、儿童寄托方式5个因素。结论重庆市城区学龄前儿童蛲虫感染率显著低于农村地区,应把农村、高年龄组、父母外出打工、卫生习惯不好、寄托儿童作为防治重点。

Objective To find out the economic laws of hy- pertensive patients. Hospitalization demand of three levels hospitals in New Rural Cooperative Medical System （ NCMS ） in Sihui county, Guangdong province, thus to provide references for further adjusting the medical service demand reasonably in the future. Methods The linear regression and power function regression models of hospitalization demand were established to measure the elasticity of demand of hypertensive patients in 13 towns of Sihui county. Results The price elasticity of hospitalization de- mand of township hospitals, county hospitals, and large size tertiary hospi- tals were - 0. 9642, - 1. 4441, - 0. 8292 respectively ; the income elastic- ity were 0. 1908,0. 1600,1. 2563 respectively. Conclusion The reim- bursement ratio of county hospital in NCMS should be decreased, while in- creasing the township hospital reimbursement ratio to guide the hypertensive oatients seeking treatment behavior reasonably.
