Continuous monitoring of fetal gross movement and maternal glucose level using newly developed methods.

BACKGROUND

There is no consensus on the relationship between maternal glucose levels and fetal movements.

OBJECTIVE

This study aimed to investigate the correlation between gross fetal movements and maternal glucose levels in the hours around food intake.

STUDY DESIGN

This was an observational study with 2 newly developed technologies, which were a glucose monitoring system and a fetal movement acceleration measurement recorder. A total of 15 women with singleton pregnancies were provided with the glucose monitoring system that automatically recorded their glucose levels every 15 minutes. In addition, fetal movements were recorded using the fetal movement acceleration measurement recorder, for 4 hours starting from 1 hour before lunch, once a week beginning at 28 weeks of gestation. For the four 1-hour periods, the ratios of the number of 10-second epochs with fetal movement divided by the total number of epochs (defined as the fetal movement parameter) were compared at the earlier (28-33 weeks of gestation), later (34-39 weeks of gestation), and overall (28-39 weeks of gestation) gestational weeks using analysis of variance analyses. A linear regression analysis was developed between the glucose level and the movement parameter for the earlier, later, and overall gestational weeks. All data were divided into 4 categories: (1) both the glucose level and the fetal movement parameter increased from the previous 15 minutes; (2) the glucose level increased, but the fetal movement parameter did not increase; (3) the glucose level did not increase, but the fetal movement parameter increased; and (4) both glucose level and fetal movement parameter did not increase. The numbers for each category were compared for the earlier, later, and overall gestational weeks using χ

RESULTS

There was no significant change in the fetal movement parameter among the four 1-hour periods at the earlier (

CONCLUSION

Having a meal did not change gross fetal movement counting; however, there are positive correlations between maternal glucose level and gross fetal movement at 28 to 33 weeks of gestation, but not at 34 to 39 weeks of gestation, for both glucose values and value changes under natural conditions of the mother and fetus.
