Based on the hypothesis that various changes occurring in pregnant women during pregnancy are contributory factors to domestic accidents, multivariate analysis was carried out to clarify the multidimensional relationship between such changes and domestic accidents. Pregnant women were classified into four categories depending on their stage of pregnancy, the extent of physical changes, and the presence or absence of physiological changes. Each category was found to have certain characteristics relating to changes in ADL and occurrence of accidents. Furthermore, types of accidents and their locations could be clarified by grouping together multiple changes in ADL.
