Sleep is usually distributed during pregnancy by the fluctuation of hormones and the constantly changing body caused by the fetus1. Obesity during pregnancy causes complications for the mother, as well as, the baby. Gestational diabetes, sleep apnea, preeclampsia, preterm birth and birth defects are a few of the complications that obesity may cause2.
ρ=0.781 p=0.001
ρ=0.733 p=0.003
OBJECTIVE
The purpose of this study is to determine if there is a relationship between sleep disturbance, sleep quality or sleep quantity and the accumulation of abdominal fat during pregnancy.
ρ=0.560 p=0.046
ρ=0.185 p=0.527
METHODS
Twenty-five pregnant women were recruited from a local OB/GYN office during their first pregnancy.
Participants visited the KSU exercise physiology laboratory to obtain body composition measurements between 17 and 21 weeks gestation.
Overall sleep disturbance, quality, and quantity were assessed through a sleep disturbance survey. Six subjects were excluded from the analysis for failed validity.
Ultrasound was used to measure abdominal fat in four locations: intra-abdominal adipose tissue (IAAT) and subcutaneous adipose tissue (SAT 1), located 1 cm above the umbilicus, and preperitoneal adipose tissue (PAT) and subcutaneous adipose tissue (SAT 2), located immediately below the xiphoid process of the sternum.
Percent body fat was determined using the InBody720 Bioimpedance analyzer.
Spearman’s Correlation analyses were used to assess relationships.
*IAAT, intra-abdominal adipose tissue; SAT1, subcutaneous adipose tissue 1; PAT, preperitoneal adipose tissue; and SAT2, subcutaneous tissue 2
*Sleep disturbance, sleep quality and sleep quantity are scales; the higher the number the worse the disturbance, quality and quantity
CONCLUSIONS
There is a positive relationship between sleep disturbance and the accumulation of abdominal fat (IAAT) independent of the influence of overall adiposity. These results indicate that sleep disturbance is strongly associated with abdominal fat accumulation, whether or not the person is obese.
