Determinants of Childhood Immunization Uptake among Socio-Economically Disadvantaged Migrants in East China

OBJECTIVE To determine the coverage of childhood immunization appropriate for age among socio-economically disadvantaged recent migrants living in East China and to identify the determinants of full immunization uptake among these migrant children. METHODS This is a cross-sectional survey of 1,426 migrant mothers with a child aged ≤ 24 months, who were interviewed with a pretested questionnaire. Various vaccines, migration history and some other social-demographic and income details were collected. Single-level logistic regression analyses were applied to identify the determinants of full immunization status. RESULTS Immunization coverage rates are lower among migrants and even lower among recent migrants. The likelihood of a child receiving full immunization rise with parents' educational level and the frequency of mother's utilization of health care. Higher household income also significantly increase the likelihood of full immunization, as dose post-natal visits by a health worker. CONCLUSIONS Recent migrant status favours low immunization uptake, particularly in the vulnerability context of alienation and livelihood insecurity. Services must be delivered with a focus on recent migrants. Investments are needed in education, socio-economic development and secure livelihoods to improve and sustain equitable health care services.
