In the Mitoyo and Kanonji areas, Kagawa Prefecture, Japan, we have newly developed a simple health record booklet for parents with children called “My Karte”, which is an enlarged edition of the maternal and child health handbook. Our municipality borough gives this booklet together with the maternal and child handbook to all pregnant women without exception. In this booklet, care personnel or child by themselves write down the health condition and body development of the child, including medical examination records and vaccinations. From an overview of this simple record, healthcare practitioners, caretakers or school nurses can immediately grasp the child’s body condition, for example, whether the child is overweight or underweight, and various health problems early and precisely. In addition, the child and care personnel can evaluate the health condition of the child through self-assessment. We hope that the self-assessment will promote health during the child’s life. Moreover we are planning to collect and analyze the data from the distributed My Karte. The analyzed results will be released to the public, which will promote health consciousness in this area and give healthcare professionals basic and important data useful for daily medical practice.
