To evaluate retrospectively the satisfaction of continuous subcutaneous insulin infusion (CSII) compared to multiple daily infusions in Japanese women with diabetes mellitus (DM) during pregnancy, we examined 27 women with type 1 (n = 20) or type 2 (n = 6) diabetes mellitus or gestational diabetes (n = 1) who previously used CSII. Among these patients, 19 had used CSII during pregnancy, which accounted for 30 births. Questionnaires were retrospectively administered. The mean age of patients was 36.5 ± 7.0 years. The average birth weight was 3.1 ± 0.6 kg, with 62% of babies exhibiting complications. The satisfaction level of CSII for patients during pregnancy was 3.95 ± 0.26, whereas it was 1.84 ± 0.26 for multiple daily infusions (P
