The effects of melatonin and magnesium in a novel supplement delivery system on sleep scores, body composition and metabolism in otherwise healthy individuals with sleep disturbances. Chronobiol Int 2024; 41:817-828.

Abstract
The purpose of this study was to investigate the effects of a novel dietary supplement, including melatonin and magnesium, delivered via coffee pods on sleep quality, resting metabolic rate (RMR), and body composition in individuals with poor sleep quality disturbances. Using a double-blinded, randomized, crossover trial, we recruited 35 participants to a 4-week intervention with both supplements (1.9 mg melatonin + 200 mg elemental magnesium before sleep) and placebo conditions, considering a 7d washout period between treatments. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was applied, RMR (kcal) was measured using indirect calorimetry (canopy ventilated open-circuit system) and body composition was assessed using dual-energy X-ray absorptiometry. Decreases in PSQI and anger - hostility scores, as well as in energy intake and fat mass, were observed (p < 0.05) for both conditions, from baseline to the end of each 4-week intervention. Differences between conditions were also observed for these parameters along with energy spent in activity, number of sedentary breaks, sleep efficiency, latency time, time in bed, total sleep time, awakening time, and movement index (p < 0.05) favouring the supplement condition. However, the final PSQI questionnaire scores still indicated poor sleep quality on average (PSQI > 5), in both conditions, with no changes regarding RMR. A melatonin-magnesium supplement, in a coffee pod format, showed improvements in sleep quality in otherwise healthy individuals with sleep disturbances, however PSQI questionnaire scores still indicated poor quality on average (PSQI > 5).

Abstract
STUDY OBJECTIVES This study examined the relationship between total sleep time and chronic diseases among people with disabilities using data from the Panel Survey of Employment for the Disabled to identify differences according to sex and age. METHODS This study analyzed secondary data analysis from the second wave of the Panel Survey of Employment for the Disabled (collected 2016-2018; n = 5,092) using a generalized estimating equation model and chi-square test. RESULTS The main findings were these: First, the incidence of chronic disease was 1.84 and 1.24 times higher among patients with disabilities who slept less than 5 and 6 hours per night, respectively, than those who slept 7 hours. Second, female patients experienced more sleep problems than male patients. Third, chronic disease was most prevalent among patients with the shortest sleep time, regardless of age. CONCLUSIONS The results suggested that patients with disabilities who slept less than 6 hours per night were more likely to experience chronic diseases than those who slept more than 6 hours, with women especially vulnerable. Future research should consider multiple variables to clarify the relationship between total sleep time and health-related outcomes associated with various disabilities and chronic diseases.

Psychosocial factors affecting sleep quality of pre-employed firefighters: a cross-sectional study. Ann Occup Environ Med 2020; 32:e12. [PMID: 32528689 PMCID: PMC7272383 DOI: 10.35371/aoem.2020.32.e12] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 04/21/2020] [Indexed: 11/29/2022] Open
Abstract
Background There have been no health-related studies of pre-employed firefighters without firefighter-specific job-related factors (FSJRF). This study aimed to evaluate the sleep quality of pre-employed firefighters and to examine the relationship between sleep quality and psychosocial factors. Methods We conducted a self-report questionnaire survey for 602 pre-employed firefighters at 3 Fire Service Academies after brief lecture about sleep. Sleep quality and psychosocial variables such as depression, anxiety, stress and social support were evaluated. The independent 2 sample t-test, χ2 test and multiple logistic regression analysis were used to evaluate the effect of the variables on the sleep quality of pre-employed firefighters. Results Among a total of 602 people, 347 (57.6%) had good sleep quality and 255 (42.4%) had poor sleep quality. Pittsburgh Sleep Quality Index score of them was 3.29 ± 1.41) and 7.87 ± 2.20), respectively. 24 (4.0%) were evaluated to have insomnia by Insomnia Severity Index. Logistic regression analyses showed that the depression (adjusted odds ratio [aOR]: 5.940, 95% confidence interval [CI]: 3.124–11.292), anxiety (aOR: 4.233, 95% CI: 2.138–8.381), stress (aOR: 2.880, 95% CI: 1.915–4.330) and social support (aOR: 0.959, 95% CI: 0.939–0.980) have a significant effect on sleep quality after adjusted by sex, age, smoking status, drinking status, caffeine intake, past shift working and circadian rhythm type. Conclusions Depression, anxiety, stress and social support were associated with sleep quality among pre-employed firefighters. Repeated follow-up studies of pre-employed firefighters are needed to further assess their change of sleep quality and identify the FSJRF that may affect the sleep quality of firefighters.

Abstract
This study was performed to identify the factors influencing gender differences in sleep quality between men and women. A cross-sectional survey was conducted using a convenience sample of 300 young adults from three Korean universities. Participants were 20-40 years of age, used smartphones, and took no sleep medication. Participants completed questionnaires on sleep quality, exercise, stress, depression, and smart phone addiction. The predictors of sleep quality in men were coffee consumption, napping, depression, failure to engage in light exercise at least three times per week, being overweight, being in the potential smart phone addiction group, and being employed, which explained 30.2% of the variance. The predictors of sleep quality in women were education to college level or higher, smoking, and stress, which explained 30.5% of the variance. To improve sleep quality in this population, future intervention should contain life style modification strategies containing smartphone addiction prevention.
