The Frequency and Associated Factors of Restless Leg Syndrome among Pregnant Women in 3rd Trimester

Background: Restless leg syndrome (RLS), also known as Willis-Ekbom disease, is characterized by an uncomfortable sensation in the legs, often occurring at the onset of sleep, which triggers an irrepressible urge to move the legs. This condition is particularly prevalent among pregnant women, with symptoms typically worsening during the third trimester. Despite its impact, many pregnant women are unaware of RLS, attributing their discomfort to normal pregnancy symptoms. Objective: To assess the frequency and associated factors of RLS in pregnant females during the third trimester and to evaluate its impact on their quality of life. Methods: A cross-sectional study was conducted involving 250 pregnant females in their third trimester, recruited from Shalimar Hospital, Nawaz Sharif Hospital, Zahida Welfare Trust, Alshad Clinic, Ali Hospital, Ahsan Hospital, Nargis Clinic, Manawa Government Hospital, and Sultan Medical Center. Participants aged 15-45 years were included, while those with rheumatoid arthritis, diabetes mellitus, neurological disorders, preeclampsia, and gestational diabetes mellitus were excluded. Data were collected using structured questionnaires incorporating the International Restless Legs Syndrome Study Group (IRLSSG) criteria and the Pittsburgh Sleep Quality Index (PSQI). Ethical approval was obtained, and the study adhered to the Declaration of Helsinki principles. Statistical analysis was performed using SPSS version 25, with descriptive statistics, frequencies, and graphical representations employed to summarize and analyze the data. Results: The mean age of participants was 26.32 years (SD = 5.08). The prevalence of RLS in the third trimester was found to be 89.2%. The age group most affected was 18-23 years. Factors associated with RLS included inadequate calcium intake (40.4%), insufficient daily water intake (40.4%), poor food intake (48%), mood disturbances (89.2%), lack of movement or light exercise (78%), caffeine consumption (16%), disturbances in sexual activities (48%), and disruption in daily activities (45.2%). Conclusion: RLS is highly prevalent among pregnant women, particularly in the third trimester, significantly impacting their quality of life. Despite its prevalence, many women remain unaware of RLS, mistaking it for typical pregnancy discomfort. Raising awareness and implementing screening and management strategies during prenatal care could improve the quality of life for affected women.
