[Changes in shape and size of the foot during pregnancy].

Many women report an increase in foot size during their pregnancy. Our objective was to verify this anecdotal evidence. In an initial survey of 21 mothers in 2 Münster nursery schools we found a tendency towards an increase in foot size during pregnancy. We therefore developed a measuring system to measure changes in foot length, width, height and volume. A total of 40 women recruited from the antenatal clinic of the University Hospital of Münster and a participating practice were seen three times during their pregnancy. The results were analysed using the Wilcoxon test. We found a statistically significant increase in foot length, width and volume, whereas foot height decreased slightly. This difference was, however, not significant. Especially in diabetic women with polyneuropathy it is important to pay attention to shoe size to prevent pressure sores.
