【Abstract】 Objective To study the situation of child health care and its regional distribution characteristics in31 provinces in China in 2014, so as to provide reference for the planning and decision-making of child health care.Methods Six related indexes of child health care in 31 provinces in China in 2014 were collected and analyzed withSpearman correlation analysis and hierarchical clustering analysis using Ward's method. Results The positively corre-lated indexes were as follows: the ratio of infants with birth weight<2,500 g and visiting rate of newborns; the visitingrate of newborns and system administration rate of children under 3 years old, as well as health care administration rateof children under 7 years old; the system administration rate of children under 3 years old and health care administrationrate of children under 7 years old. The negatively correlated indexes were as follows: the proportion of children under 5years old with moderately or severe malnutrition and visiting rate of newborns, the system administration rate of childrenunder 3 years old, and the health care administration rate of children under 7 years old. Tibet, with 5 indexes ranking firstor last in Mainland China, was firstly clustered into one distinctive group. Conclusion The level of child health care inChina varies greatly and its distribution is uneven. Appropriate measures should be taken to promote the healthy develop-ment of children's health care.
