摘要：The purpose of this study was to investigate the characteristics related to participation status in the Ibaraki Cohort Study and discuss ways to support the continuation of the survey. Although there were no significant differences in age or number of pregnant weeks among the registration group, dropout group, and continuation group, the results of binomial logistic analysis showed that the number of consulting partners were related to survey continuation (p<.10). It was suggested that connection with others was important for the continuation of the survey.
