Abstract

OBJECTIVE:

To perform a detailed epidemiological study of Chinese women and the relationship between restless legs syndrome (RLS) in pregnancy and any associated complications during delivery.

METHODS:

A total of 3874 pregnant women (18-40 years) who had delivered babies at The First Affiliated Hospital of Zhengzhou University from May 2011 to May 2014 were enrolled in the study. Using a face-to-face interview questionnaire, data were collected pertaining to RLS incidence in pregnancy and any associated complications during delivery. The relationship between RLS frequency and pregnancy or delivery complications was further investigated.

RESULTS:

Among 12.3% of the eligible participants, RLS prevalence occurred at least weekly. Older pregnant women were more likely to suffer from RLS. Individuals who experienced RLS at least weekly reported a statistically higher frequency of excessive daytime sleepiness and an increased prevalence of hypertension, cardiovascular disease, and preeclampsia compared with those without RLS.

CONCLUSION:

The study revealed that RLS was frequent in Chinese pregnant women, especially in those with pregnancy or delivery complications such as hypertension, cardiovascular disease, and preeclampsia. Restless legs syndrome was also associated with excessive daytime sleepiness.
