Asian American Pacific Islander (AAPI) children face an increased risk for acquiring hepatitis B virus infection. Since 1990, the Centers for Disease Control and Prevention have recommended universal hepatitis B immunization for AAPI children. In 1997, Illinois passed a law requiring hepatitis B vaccination for school entry, but its implementation was restricted to pre-kindergarten and fifth-grade students. That same year, the Illinois Health Education Consortium (IHEC) began the Hepatitis B Immunization Catch-Up Project in collaboration with the Chicago Public Schools (CPS) and community organizations. Schools targeted for IHEC intervention were those enrolling more than 100 (or over 20%) AAPI students. This study describes the effects of the Illinois law and the Hepatitis B Immunization Catch-Up Project on hepatitis B immunization of AAPI students in the CPS in 1999.
The effects of the IHEC Catch-Up Project intervention and the Illinois law upon hepatitis B immunization was tested using a two-way analysis of variance for the 1999-2000 cohort of AAPI students enrolled in the CPS as of November 1999.
Results indicated students required to receive hepatitis B immunization shots received a significantly (p < .001) higher mean number of shots than was the case for students who were not required to receive the shots. Similarly, IHEC-intervention students received a significantly (p < .001 ) higher mean number of shots than was the case for students who were not part of the IHEC intervention.
The IHEC intervention produced a significant, positive effect on the hepatitis B immunization rate above and beyond the state law. The practical significance of the IHEC intervention is described and discussed.
亚太裔美国儿童感染乙型肝炎病毒的风险增加。自1990年以来，疾病控制与预防中心建议对亚太裔美国儿童进行普遍的乙型肝炎免疫接种。1997年，伊利诺伊州通过了一项法律，要求入学时接种乙型肝炎疫苗，但实施范围仅限于学前班和五年级学生。同年，伊利诺伊州健康教育联盟（IHEC）与芝加哥公立学校（CPS）及社区组织合作开展了乙型肝炎免疫补种项目。IHEC干预的目标学校是那些招收100多名（或超过20%）亚太裔美国学生的学校。本研究描述了1999年伊利诺伊州法律和乙型肝炎免疫补种项目对芝加哥公立学校亚太裔美国学生乙型肝炎免疫接种的影响。
使用双向方差分析对截至1999年11月在芝加哥公立学校就读的1999 - 2000学年亚太裔美国学生队列进行研究，以测试IHEC补种项目干预和伊利诺伊州法律对乙型肝炎免疫接种的影响。
结果表明，被要求接种乙型肝炎疫苗的学生平均接种次数显著高于（p < .001）未被要求接种的学生。同样，参与IHEC干预的学生平均接种次数显著高于（p < .001）未参与IHEC干预的学生。
IHEC干预对乙型肝炎免疫接种率产生了显著的积极影响，其效果超出了州法律的作用。文中描述并讨论了IHEC干预的实际意义。
