Abstract: Devices, systems and methods assess one or more of the risk of an allergy, immediate and/or later in life, for the infant or young child; the risk of an underdeveloped immune system, immediate and/or later in life, for the infant or young child, and/or the immediate risk of a not well-functioning digestive system for the infant or young child, preferably all of these. Optionally, the risk of obesity, immediate and/or later in life, can be additionally assessed. Thus a user such as a parent can evaluate the health characteristics of the infant or young child and receive recommendations, such as a suggestion to visit to a healthcare professional. A device including a processor can provide an interactive tool that requests information related to the one or more health risks and uses the information to assess the presence or absence of the health risks for the infant or young child.
