R. Gershonibaruch et al., ACTIGRAPHIC HOME-MONITORING OF THE SLEEP PATTERNS OF IN-VITRO FERTILIZATION CHILDREN AND THEIR MATCHED CONTROLS, Developmental Medicine and Child Neurology, 36(7), 1994, pp. 639-645
The sleep patterns of 35 in vitro fertilization (IVF) children aged 19
to 57 months and their matched controls were evaluated by actigraphic
home-monitoring for three consecutive nights. Actigraphic data were a
nalysed by an automated scoring procedure developed in the authors' la
boratory. There were no significant differences in activity levels bet
ween IVF multiple-birth subjects and their matched controls or between
IVF singletons and their matched controls. In contrast, multiple-birt
h subjects had higher activity levels during sleep and lower sleep eff
iciency than singletons in both IVF and control groups. Sleep measures
showed night-to-night stability in all groups.
