AI Article Synopsis
- The study aimed to explore differences in sleep patterns between weekdays and weekends in patients with type 2 diabetes, and how these patterns relate to glycaemic control.
- Results indicated that there were no significant differences in overall sleep parameters between the two timeframes, although participants slept slightly longer and went to bed later on weekends.
- It was found that greater variability in sleep duration and timing was associated with higher levels of haemoglobin A1C, suggesting the importance of stable sleep habits for managing diabetes.
Article Abstract
Aims: To examine whether there were significant differences in sleep during weekdays/weekends and whether the intra-individual variability in sleep was related to glycaemic control in patients with type 2 diabetes.
Design: Correlational, longitudinal design.
Methods: Data were collected between February 2017-January 2018. In all, 56 adults with type 2 diabetes were included (60.7 years, 55.4% female). Sleep was measured using the Consensus Sleep Diary over 8 days. Intra-individual variability of sleep was calculated as the standard deviation of sleep variables. Standard deviations of sleep duration, sleep efficiency, sleep quality, and mid-sleep time were obtained. Glycaemic control was measured by haemoglobin A1C. Paired t test and multiple regression analysis were used.
Results: Overall, there were no differences in sleep parameters between weekdays and weekends. Participants slept 20 min more over the weekends than during weekdays. The mid-sleep time during weekends was about 35 min later than during weekdays. Intra-individual variability of sleep duration and mid-sleep ranged from 27.6-167.4 min and 13-137 min, respectively. Controlling for covariates (e.g., distress, symptoms, and self-care), larger variability in sleep duration, and mid-sleep were significantly related to higher A1C levels.
Conclusion: Diabetes educators are recommended to include the assessment of intra-individual variability in sleep. Maintaining a regular sleep habit (e.g., sleep duration and sleep timing) should be highlighted during patient education.
Impact: Intra-individual variability in sleep is an alternative dimension for sleep assessment. This study examined whether intra-individual variability in sleep was related to glycaemic control in an older sample of type 2 diabetes patients using a sleep diary across 8 days. This sample had a similar sleep pattern during weekdays and weekends. Larger intra-individual variabilities in sleep duration and mid-sleep time were independently related to worse glycaemic control. Diabetes patients are recommended to maintain a regular sleep routine.

The social determinants of health (SDOH) have been recognized as an important contributor to an individual's health status. A valid and reliable instrument is needed for researchers and clinicians to measure SDOH. However, there is considerable variability in the screening methodologies, as well as a lack of standardization in definitions and methods for capturing and reporting SDOH data for both electronic health record software vendors and national experts on SDOH.

Background: The increasing prevalence of primary hypertension among children and adolescents is a global health concern, with inadequate sleep duration identified as a significant risk factor. This study investigates the impact of weekday-weekend sleep duration gap (WWSDG) on hypertension among American adolescents.
Methods: Using data from the NHANES 2017-2020 cohort, we analyzed sleep patterns and hypertension prevalence among 430 adolescents.

Purpose: This study aims to compare the prevalence of depression and related geriatric syndromes in earlier-onset rheumatoid arthritis (EORA) patients, who have experienced prolonged inflammation and medication use, with those with late-onset rheumatoid arthritis (LORA) patients, who often present with an acute and severe course.
Methods: In this multidisciplinary study, patients with EORA and LORA aged 60 and over who were referred to a tertiary rheumatology clinic underwent a geronto-rheumatologic evaluation. Muscle mass and handgrip strength, cognitive function, nutritional status, Fried frailty index, fall history, gait speed, depression according to Geriatric Depression Scale and Insomnia Severity Index were recorded.

Background: Non-invasive ventilation (NIV) uses positive pressure to assist people with respiratory muscle weakness or severe respiratory compromise to breathe. Most people use this treatment during sleep when breathing is most susceptible to instability. The benefits of using NIV in motor neurone disease (MND) are well-established.

Research suggests a bidirectional association between sleep disturbances and posttraumatic stress disorder (PTSD) symptoms. However, most studies have been conducted with group-level data, which do not necessarily capture the associations between PTSD symptoms and sleep within an individual over time. This study aimed to add to the literature concerning the association between sleep and PTSD and extend these findings to investigate the effect of sleep disturbances on positive affect.
