Relationship between sleep-disordered breathing and
sleeping position at the 37th week of pregnancy: An
observational cross-sectional study
Midori Ura
Junshin Gakuen University, Japan
Purpose: Sleeping in the lateral positionduringpregnancy
can potentially reduce the severity of sleep disordered
breathing (SDB). However, this hypothesis has not been
formally investigated in pregnant women. Unlike previous
studies that have relied largely on self-reportedmeasures
of sleeping position, we investigated the relationship
between SDB and sleeping position during late pregnancy
using objective measurements.
Methods: Thirty pregnant women at the 37th gestational
week and 30 non-pregnant women (n-Pr) participated
in the present study. The pregnant women were divided
into two groups: those with body mass index (BMI) ≥30
kg/m2 (with obesity, p-Ob), and those with BMI <30 kg/
m2 (without obesity, p-nOb). Data were collected using a
portable screening device to detect SDB indicated by the
respiratory disturbance index (RDI) as well as sleeping
position.
Results: The occurrence of the lateral sleeping position
was higher in pregnant women than in n-Pr (P < .05). The
total RDI significantly differed among the three groups [P
< .01; p-Ob, 10.7 (3.1); p-nOb, 7.0 (3.0); n-Pr, 4.3 (2.9)]. The
p-Ob group showed significantly lower RDI in the lateral
position than in the supine position (P = .04). Moreover,
there was a significant difference in RDI between p-Ob
and p-nOb for the supine position (P = .001), but there
was no between group difference for the lateral position.
Conclusions: Sleeping in the lateral position is likely to
mitigate existing SDB in pregnant women with obesity
in late pregnancy and may be an effective precaution
against undiagnosed SDB and associated complications.
Biography
Midori Ura started working as a Medical Technologist in Tokyo
after graduating from University. She completed her Master’s
Degree in Public Health in the United Kingdom, following which
she participated in organizations for international cooperation,
such as JICA (Japan International Cooperation Agency) and
UNFPA (United Nations Population Fund), and did a research
project on the developing countries for the purpose of global
health. In order to be a qualified technologist, she started work-
ing as a Medical Technologist at the Shinshu University Hospi-
tal, Japan again and has obtained the Registered Medical So-
nographer certification in the field of vascular and OBGYN in-
cluding fetus screening. In the meantime, she also completed
her PhD in Health Science at Shinshu University in Japan. She
has been a Lecturer of Clinical Physiology and Public Health at
Junshin Gakuen Univeristy.
