"The study sought to evaluate smartwatch-based sleep quality indicators of fitness to work. Eighteen males (aged 20–26 years) were assigned to three randomized daytime sleep conditions (bad/moderate/good), which varied in terms of lighting, noise, and temperature, for a six-hour period. After this daytime sleep, participants completed simulated computer tasks during a 12-hour nighttime waking period. Prior to those tasks, participants’ fitness to work was determined by subjective measures that included the Sleep Quality Index-Karolinska Sleep Diary (SQI-KSD)), the Psychomotor Vigilance Task (PVT)), and the Karolinska Sleepiness Scale (KSS) to measure drowsiness. Total sleep time (TST), light sleep quantity (LSQ), deep sleep quantity (DSQ), and REM sleep quantity (REMSQ) were recorded using a smartwatch. The results confirmed that TST, LSQ, and SQI-KSD can be used as measures of sleep quality and fitness to work (p < 0.05)."

"ABSTRAKAktivitas fisik dan kualitas tidur merupakan dua faktor penting yang dapat berpengaruh pada kesehatan. Pekerja perkantoran merupakan individu yang rentan terhadap pola hidup sedenter, sehingga memiliki tingkat aktivitas fisik yang rendah. Tingkat aktivitas fisik yang rendah ini diduga memiliki pengaruh terhadap kualitas tidur dari para pekerja perkantoran. Penelitian ini bertujuan untuk melihat hubungan aktivitas fisik pada kualitas tidur pekerja perkantoran.Metode penelitian ini adalah potong lintang dengan subjek penelitian pekerja perkantoran di Jakarta. Data aktivitas fisik diperoleh dari pengisian International Physical Activity Questionnaire (IPAQ) versi Bahasa Indonesia dan data kualitas tidur diperoleh dari pengukuran Pittsburghs Sleep Questionnaire Index (PSQI) versi Bahasa Indonesia.Hasil yang ditemukan adalah rerata jumlah energi ekspenditur subjek penelitian adalah 2865 MET-menit/minggu dan rerata indeks kualitas tidur subjek penelitian adalah 6. Hasil penelitian ini menunjukkan bahwa tidak ada korelasi yang bermakna antara jumlah energi ekspenditur dan indeks kualitas tidur pekerja perkantoran di Jakarta dengan kekuatan korelasi yang bisa diabaikan (p = 0,28; r = 0,15).Hubungan aktivitas fisik dan kualitas tidur terjadi secara tidak langsung. Kualitas tidur dipengaruhi oleh beberapa faktor, diantaranya adalah kelelahan dan tingkat stres. Aktivitas fisik dapat menurunkan risiko terjadinya kelelahan dan stres, yang secara tidak langsung dapat meningkatkan kualitas tidur.

ABSTRACT

Physical activity and sleep quality are two of important factor that may affect our health. Office workers are individuals who are vulnerable to having a sedentary lifestyle, so they lack of physical activity. Lack of physical activity suspected to be related to sleep quality in office workers. This study aimed to examine the correlation between physical activity and sleep quality in office workers.

The method of his study is cross-sectional and the subjects are office workers at Jakarta. The physical activity data was acquired from International Physical Activity Questionnaire (IPAQ) Indonesian version and the sleep quality data was acquired from Pittsburghs Sleep Questionnaire Index (PSQI) Indonesian version.

Results of the data founds subjects median of total energy expenditure is 2865 MET-minutes/weeks and subjects median of sleep quality index is 6. The result of this study showed that there is no significant correlation between total energy expenditure and sleep quality index in office workers at Jakarta with the neglectable power of correlation (p = 0,28; r = 0,15).

The relation between physical activity and sleep quality are indirectly. Sleep quality is affected by several factors, among them are fatigue and stress. Physical activity may decrease the risk of fatigue and stress, that are indirectly may increase sleep quality.

"Research over the past decade has begun to show the many ways in which work affects sleep, and sleep affects work; this book brings all these research findings together in a state-of-the-art review. The book opens with a chapter on sleep disorders meant to ground organizational researchers in the science of sleep. Workplace issues that have benefitted from research for decades, such as shift work, occupational safety and road and transportation are covered in detail. In addition, emerging topics such as the intersection of sleep and work stress and non-work experiences, mood and emotions, energy management, unethical behaviors and work withdrawal (e.g., absenteeism) are considered in detail. Given the changing demographic composition of many workplaces, a separate chapter focuses on sleep and older workers. The book concludes with a consideration of how this information must now be integrated into the curricula of all business programs to enhance the practice of management, and individual and organizational functioning."

Background. Sleep disorders are prevalent in adolescents and may influence their academic achievement at school. However, in Indonesia, no research has ever been done to study academic achievement in students with sleep disorders and related factors.

Objectives. This study aimed to define: (1) the prevalence of sleep disorders and their patterns based on the SDSC questionnaire, (2) the proportion of junior high school students having low average academic achievement, (3) the relationship between factors; i.e gender, motivation and learning strategies, IQ level, mothers' educational level, socioeconomic level, family structure, non-formal education, TV/computer set inside the bedroom, sleep duration during schooldays, bedtimewakeup time difference; and the academic achievement in junior high school students with sleep disorders.

Method. This was an analytical cross-sectional study, performed at five junior high schools in Jakarta between January to March 2013. Screening for sleep disorders, based on the Sleep Disturbance Scale for Children questionnaires, was done in 491 junior high school students. Students who fulfilled the criteria of sleep disorders, were asked to fill in the Motivated Strategies for Learning Questionnaire (MSLQ). The IQ level of each subjects was also measured.

Results. There were 129 subjects who fulfilled the sleep disorders criteria. Four subjects were dropped out due to they didn?t have IQ level. The prevalence of sleep disorder in this study was 39.7%, mostly difficulty in initiating and maintaining sleep (70.2%). There were 47.6% subjects had low average academic achievement. As many as 13 subjects had low average IQ level and were not included in bivariate and multivariate analysis. Subjects mostly female (71%), with middle-low income (58.9%), had moderate motivation and learning strategies (72.6%), and attended non-formal education (87.9%). Based on the logistic regression analysis, the most influencing factors to the low average academic achievement are consecutively: the non-formal education ( > 2 types, non-academic), the average IQ level, and male sex.

Conclusion. The prevalence of sleep disorders in junior high school students in Jakarta are 39.7%, mostly difficulty in initiating and maintaining sleep. There were 47.6% subjects had low average grade. Factors related to the low average academic achievement are non-formal education ( > 2 types, non-academic), the average IQ level, and male sex."
