Equality of public health service and family doctor contract service utilisation among migrants in China.

China initiated the equalisation of an essential public health service programme in 2009 with the goal of developing a more equitable and effective public health system for all people. This study employs data from the China Migrants Dynamic Survey to examine regional-level and household-level income-related inequalities in public health service utilisation and its determinants. Wagstaff concentration indices indicate that essential public health services and family doctor contract services are concentrated among less developed prefectures and poorer households. Decomposition analysis based on recentered influence function regression shows that education contributes to pro-poor inequality in health records and health education utilisation. China's policies of essential public health services and family doctor contract services reduce income-related inequalities in health service utilisation, which has important implications for developing countries striving to achieve universal health service coverage and equal health outcomes.
