title: Investigation of the age of release from the diaper environment.
abstract: The use of disposable diapers in Japan is increasing. It has been observed, however, that, because their dry touch prevents infants from feeling wetness, disposable diaper use may prolong the time of wearing diapers or delay toilet training. A study of the periods during which diapers were required was conducted on two groups, one using conventional cotton diapers and the other, disposable diapers. In addition, the same study was performed with identical twins, one sibling using cotton, and the other, disposable diapers. Results of the study revealed that the time to stopping diaper use was the same in both groups: the average was 27 months (6 months longer than the average 20 years ago). Among identical twins, no difference was observed as to notice before discharge, notice after discharge, or period of use. Therefore, there was no evidence that the dry feel of disposable diapers resulted in prolongation of diaper use.
