This study examined a wide range of literature in order to describe factors associated with the concept of infant health. The design of the study is a literature review examining 21 research studies, written in the English language. The study explored which factors were found to exert an influence on the concept of infant health. The result showed that the concept infant health is dependent on many factors but what seems to exert an influence are foremost maternal health and well-being, the family's health care utilization and the parental assessment of their own health. Additional studies are needed to fully understand the concept of infant health. The need for an infant definition that empowers infant health arises because, if a common ground is not clearly established, miscommunication may arise. Furthermore, there is a need to initiate a model for infant health.
