本文旨在探討母親的教育程度對兒童醫療利用行為之影響,利用台灣2005年「國民健康訪問暨藥物濫用調查」 (National Health Interview Survey, 簡稱NHIS),「12歲以下個人問卷」所提供的資訊,以母親的教育程度作為衡量指標,分析兒童在門診、急診及住院的醫療使用的機率,另就家庭收入及是否購買兒童醫療保險等變數來探討其與兒童健康情形及醫療利用間之關聯性。當被解釋變數為兒童的醫療利用機率及其BMI時,採以Probit 迴歸模型研究分析;被解釋變數為兒童的醫療利用次數時,以負二項分配來量化分析;而在被解釋變數為兒童醫療花費及兒童身高時,則透過多元線性迴歸模型檢測。 實證結果顯示,在控制兒童、父母個人特徵與家庭特性下,母親教育程度對兒童醫療利用在門診使用機率、次數及花費有正向顯著的效果;在身高部分,當母親的教育程度越高,兒童身高越高。;This study aimed to examine the relation between mother′s education and child’s medical care utilization by employing observations of children aged 12 and below extracted from 2005 National Health Interview Survey (NHIS) data in Taiwan. We empirically analyze the effect of mother education on child medical care utilization that includes outpatient, emergency care and hospitalization. Moreover, we also analyze the association of family income, medical insurance status and child health with the child’s medical care utilization. Probit model, negative binomial distribution model and multiple linear regression model are employed to analyze probability, frequency and expenditure of medical care utilizations, height and BMI on the child. The research results indicated that mother′s schooling is positively related to the likelihood, frequency and expenditures of outpatient care, given the child’s, parental and family’s characteristics have been taken into consideration. Furthermore, height is positive correlation with mother′s education.
