To evaluate the prevalence of poor sleep quality and identify its associated factors among third-trimester pregnant women attending a public healthcare service in a municipality in Goiás, Brazil. This was a cross-sectional, analytical, and epidemiological study conducted with a probabilistic sample of 243 pregnant women. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), along with sociodemographic, behavioral, health, sexual, and pregnancy-related variables. Data were analyzed using Poisson regression with robust variance to estimate prevalence ratios (PR) and their respective 95
Sleep disturbance and non-motor symptoms contribute significantly to the overall disease impact and impaired quality of life (QoL) in cervical dystonia (CD). In Indian populations polysomnographic studies are limited. Our aim was to examine sleep quality and architecture using questionnaires and PSG and to assess the correlations between the severity of the disease, QoL, and psychiatric characteristics. We enrolled 40 patients with isolated CD and 20 healthy controls at a tertiary care center in India. They underwent validated sleep questionnaires and one-night video-PSG to assess sleep parameters. Validated clinical, psychiatric, and quality-of-life scales were used. Mean age was 50.3 ± 13.7 years. PSG revealed significantly reduced total sleep time (TST) (median 172.8 min, interquartile range [IQR] 99.9–261.1), poor sleep efficiency (median 39.5
Sleep restriction (SR) impairs cognitive performance and cerebral metabolism. Creatine supplementation may elicit a metabolic and cognitive benefit following sleep loss. A randomised, cross-over trial ([ACTRN12626000301369]; retrospectively registered) was conducted with 8 healthy adults (4 women, 4 men). Cognitive performance, mood, sleepiness, perceived workload and cerebral haemoglobin oxygenation were compared between a night of unrestricted sleep and a night restricted to 3 h time-in-bed (i.e. SR), separated by 7 days of unrestricted sleep and ingestion of either 20 g⋅day−1 creatine monohydrate or tapioca (placebo). At least a 5-week washout period separated trials. Data were analysed with linear mixed models, t-tests and equivalence tests. SR slowed mean reciprocal response time and mean fastest 10
SARS-CoV-2 infection has been associated with a wide spectrum of neuropsychiatric and sleep disturbances, including insomnia. However, few studies have clinically assessed restless legs syndrome (RLS) after COVID-19, and existing literature relies largely on questionnaire-based surveys. To determine the prevalence and correlates of clinically diagnosed RLS and insomnia among adults recovering from SARS-CoV-2 infection. This cross-sectional multicentre study included adults aged 18–70 years with RT-PCR–confirmed SARS-CoV-2 infection, and they were evaluated within one month of diagnosis. Individuals with neurological disorders, use of neuropsychotropic medications, malignancy, or substance dependence were excluded. RLS was diagnosed using IRLSSG clinical criteria, and insomnia was diagnosed using ICSD-3 criteria. Demographic and clinical data, including COVID-19 severity markers, were extracted from hospital records. Group comparisons were performed using chi-square test and non-parametric tests (Mann–Whitney U or Kruskal–Wallis, as applicable). Among 224 participants (mean age 38.16 ± 15.05 years; 58.9
Hypertension may be associated with impaired sleep quality and health-related quality of life (QOL). Real-world evidence examining these outcomes together with blood pressure (BP) control and lifestyle factors among Indian adults with hypertension remains limited. This retrospective observational study included 950 adults with essential hypertension receiving routine clinical care across multiple centers in India. Sleep quality and hypertension-specific QOL were assessed using the Pittsburgh Sleep Quality Index (PSQI) and MINICHAL questionnaire, respectively. Associations were assessed using chi-square tests and independent-samples t-tests. Multivariable logistic regression using forced entry evaluated factors associated with poor sleep quality. BP changes between baseline and approximately one-month follow-up were assessed using paired t-tests. Poor sleep quality was present in 81.4
