Abstract

We modeled the proportion of right mouth opening for each fetal scan using a generalized linear mixed model, which takes account of the repeated measures design. There was a significant increase in the proportion of lateralized mouth openings over the period increasing by 11% for each week of gestational age (LRT change in deviance=10.92, 1df; p<0.001). No gender differences were found nor was there any effect of maternally reported stress on fetal lateralized mouth movements. There was also evidence of left lateralization preference in mouth movement, although no evidence of changes in lateralization bias over time. This longitudinal study provides important new insights into the development of lateralized mouth movements from 24 to 36 weeks of gestation.
