Sleep Med 2024; 115:187-192. [PMID: 38367361 DOI: 10.1016/j.sleep.2024.02.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 01/27/2024] [Accepted: 02/12/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND Caucasian patients with restless legs syndrome (RLS) frequently exhibit periodic limb movements during sleep (PLMS), which may increase the risk of hypertension. We evaluated the positivity rate of PLMS and factors associated with positivity in Japanese patients with RLS, and tested whether the complications of PLMS are associated with the presence of hypertension. METHODS We retrospectively investigated polysomnographic data and the presence or absence of hypertension in patients with RLS. Patients with systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg or those taking antihypertensive medication were categorized as the group with hypertension. RESULTS Among 468 patients, 200 (42.7%) had periodic limb movement index (PLMI) values ≥ 15/h and 108 (23.1%) met the criteria of positivity for hypertension. Multiple logistic regression analysis revealed that only higher age was significantly associated with PLMI values ≥ 15/h. Multiple linear regression analyses of factors associated with an increased PLMI also showed that increased PLMI was significantly correlated with higher age and male sex, but not with the international restless legs scale scores. Multiple logistic regression analysis also revealed that higher age and body mass index, not PLMI values ≥ 15/h, were significantly associated with the presence of hypertension. CONCLUSION The PLMS-positivity rate may be lower in Japanese patients with RLS than in Caucasian patients, and it increases with age and male sex, but not with the severity of the disorder. Furthermore, PLMS complications were not associated with the risk of hypertension in Japanese patients with RLS.

Abstract
AIM Understanding patients' hypertension (HTN) symptoms can assist healthcare professionals' awareness of individual, cultural, and behavioral responses and improve diagnostic accuracy to optimize treatment. The purpose of this review was to evaluate and synthesize current literature exploring HTN symptoms. METHODS Databases searched included MEDLINE (PubMed), CINAHL (EBSCO), Scopus, and Web of Science from January 2010 to January 2022. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The McMaster critical review forms were used to determine the quality of both qualitative and quantitative articles. Synthesis of the data was guided by the Joanna Briggs Institute Convergent Integrated Approach to Mixed Study Systematic Reviews. RESULTS In total, 41 articles were included, nine qualitative studies and 32 quantitative. The quality of the articles varied. Symptoms included commonly reported symptoms and some less prevalent, including some reporting absence of symptoms. Factors that affected symptoms included culture, beliefs, psychosocial factors, and knowledge. We also found that there may be a bidirectional relationship between symptoms and behaviors that may lead to self-management. CONCLUSION HTN is common and symptoms are frequently reported. HTN management is related to multiple factors. Symptoms continue in a number of individuals after initial diagnosis. Evaluating symptoms after initial diagnosis may help to optimally manage and meet blood pressure guidelines.

Abstract
Background The 2019 coronavirus disease (COVID-19) pandemic has been associated with a significant increase in sleep disorders. This study aimed to determine the prevalence of restless leg syndrome (RLS) and the effect of COVID-19 on RLS during the pandemic in Korea. Methods The National Sleep Survey of South Korea 2022 was employed in this study. This study was a large population-based web survey using a structural questionnaire of a four thousand representative sample of individuals aged 20-69 years in Korea. The survey was conducted between January 2022 and February 2022 during the COVID-19 pandemic. RLS was diagnosed using the Korean version of the paradigm of questions for epidemiological studies of RLS. Chronic persistent RLS was defined for individuals with RLS symptoms at least twice a week. Results Six hundred forty-nine (16.2%) and 172 (4.3%) patients were classified as having RLS and chronic persistent RLS, respectively. Female sex, being employed, the presence of COVID-19 vaccine-related adverse events, decreased sleep duration, the presence of EDS, and current treatment for insomnia were significantly associated with chronic persistent RLS. Conclusion During the COVID-19 pandemic, the prevalence of RLS and chronic persistent RLS in the adult Korean population was higher than that reported in previous studies.

Abstract
BACKGROUND Diabetes mellitus (DM) is associated with different clinical complications. The aim of this study was to explore the prevalence of RLS in people with diabetes mellitus and compare the risk of restless leg syndrome (RLS) between diabetic and non-diabetic population. METHODS We searched for studies of RLS prevalence in DM through PubMed, Embase, and Web of Science. Two authors independently completed the literature screening, data extraction, and bias risk assessment of eligible studies. All observational studies that assessed the prevalence or risk of RLS in DM were included, where the diagnosis of RLS was based on the International Restless Legs Syndrome Study Group (IRLSSG). Percentages, odds ratio (OR) with 95% confidence intervals (CI) were used to assess pooled estimates of RLS prevalence and risk based on random-effects models. Newcastle-Ottawa-scale (NOS) or a modified NOS were used to evaluate the quality of studies. FINDINGS A total of 42 studies, including 835,986 participants, met the eligibility criteria for the meta-analysis. Among them, 30 studies were included in meta-analysis to analyze the prevalence of RLS. A second meta-analysis was conducted using 31 studies to determine RLS risk between diabetes and non-diabetes. The results indicate that between 25% (95% confidence interval 21%-29%) of people with diabetes showed signs of RLS, and people with diabetes had an increased risk of developing RLS compare to people without diabetes (OR 1.98, 95%CI 1.66- 2.34, p < 0.001). However, the available evidence was limited due to potential risk of bias and variability between studies (I2 >75%), all of observational design. INTERPRETATION Our study suggests that the prevalence and risk of RLS might be higher in DM patients than in non-diabetes population. However, given limitations in the analysis and study design, the findings need to be corroborated in future studies.

Abstract
Background: Restless legs syndrome (RLS) is a common neurological disorder with unpleasant leg sensations and serious negative effects on mental and physical health. Many observational studies showed that people with RLS had a high risk of vascular diseases, including cerebrovascular and cardiovascular diseases (CVD), but the findings were conflicting. The Jidong RLS Cohort Study is a prospective cohort study designed to mainly examine whether or not RLS is associated with an increased risk of CVD. Methods and Design: The study recruited 8,867 healthy participants older than 18 years from October 2014 to December 2015. Participants received a physical examination in the Staff Hospital, Jidong Oilfield Branch, China National Petroleum Corporation. Baseline data and blood samples were collected. Restless legs syndrome was assessed using the international RLS diagnostic criteria. All of subjects would be followed up until December 2025. Major cardiovascular/cerebrovascular events including cardiac death, myocardial infarction, ischemic heart disease, heart failure, atrial fibrillation, ischemic, and hemorrhagic stroke will be the primary outcomes. Secondary outcomes include all-cause mortality, the decline in quality of life, cognitive impairment, and depression. Discussion: This study will contribute to the scientific evidence on the association between RLS and cardiovascular risks and also provide an unprecedented opportunity for early detection and prevention of CVD.

Abstract
Objective: To assess the relationship between food insecurity, sleep quality, and days with mental and physical health issues among college students. Design: An online survey was administered. Food insecurity was assessed using the ten-item Adult Food Security Survey Module. Sleep was measured using the nineteen-item Pittsburgh Sleep Quality Index (PSQI). Mental health and physical health were measured using three items from the Healthy Days Core Module. Multivariate logistic regression was conducted to assess the relationship between food insecurity, sleep quality, and days with poor mental and physical health. Setting: Twenty-two higher education institutions. Participants: College students (n 17 686) enrolled at one of twenty-two participating universities. Results: Compared with food-secure students, those classified as food insecure (43·4 %) had higher PSQI scores indicating poorer sleep quality (P < 0·0001) and reported more days with poor mental (P < 0·0001) and physical (P < 0·0001) health as well as days when mental and physical health prevented them from completing daily activities (P < 0·0001). Food-insecure students had higher adjusted odds of having poor sleep quality (adjusted OR (AOR): 1·13; 95 % CI 1·12, 1·14), days with poor physical health (AOR: 1·01; 95 % CI 1·01, 1·02), days with poor mental health (AOR: 1·03; 95 % CI 1·02, 1·03) and days when poor mental or physical health prevented them from completing daily activities (AOR: 1·03; 95 % CI 1·02, 1·04). Conclusions: College students report high food insecurity which is associated with poor mental and physical health, and sleep quality. Multi-level policy changes and campus wellness programmes are needed to prevent food insecurity and improve student health-related outcomes.
