“…Sleep lengths extracted from questionnaire studies during school time range from a minimum of 449766 min 7.29 (Wolfson & Carskadon, 1998) to 620763 min 10.20 (Gulliford et al, 1990). Hence, results presented here hold a median range within these values (Gulliford et al, 1990;Mercer et al, 1998;Wolfson & Carskadon, 1998;Lee et al, 1999;Mantz et al, 2000;Meijer et al, 2000;Laberge et al, 2001;Sorensen & Ursin, 2001). Comparisons are only tentative, since the meaning of indicators is not always the same (time in bed vs sleep length) and the method may differ.…”

“…For epidemiological purposes, most (Mercer et al, 1998;Wolfson & Carskadon, 1998;Lee et al, 1999;Mantz et al, 2000;Meijer et al, 2000;Laberge et al, 2001;Sorensen & Ursin, 2001) or proposed to parents (Gulliford et al, 1990), or else a diary kept by the subject (Thorleifsdottir et al, 2002). In these studies, differences between time spent in bed and effective sleep duration are difficult to ascertain.…”

“…Many studies indicate a decrease in total sleep length throughout puberty, mainly related to school schedules (Mercer et al, 1998;Lee et al, 1999). However, physiological sleep needs are not reduced during puberty; it is even possible that an increase is needed due to changes in the phase delay of the biological clock (Laberge et al, 2001).…”

Nutritional status, growth and sleep habits among Senegalese adolescent girls

2004

Objective: To study the relation between sleep habits, nutritional status, growth and maturation in a group of African adolescent girls. The main hypothesis to be tested was that sleep length could be an effective way to spare energy, and thus malnourished girls sleep longer than normal girls. Design: Three repeated yearly surveys (1997)(1998)(1999)) on a subsample of girls drawn from a larger study cohort on growth at adolescence. Setting: The Niakhar district in the central part of Senegal. Subject: In total, 40 girls were initially drawn. Missing girls were replaced at each round by girls having the same characteristics and belonging to the same cohort. Intervention: At each round, data on pubertal development (breast stages and occurrence of menarche), growth and nutritional status were collected. Adolescents wore an accelerometer for three or four consecutive nights and days at each round. Results: At the beginning of the survey, girls were 13.370.5 y old. They were under international reference values in weight and height. Their mean sleep duration was 8.570.9 h. Their puberty status did not influence their sleep habits; however, they slept more in March than in June, which was related to the seasonal change in daylight. There was a significant relation between body mass index and sleep habits: thinner girls slept a longer time and more quietly than the more corpulent girls. Conclusion: The nutritional status of these girls influenced their sleep habits: this may have been either a direct causal relation or a consequence of a protective attitude on the part of the mothers towards the frailer girls.

“…It would also be important to explore sex differences in the quality of adolescent sleep over time. Reports are conflicting in this regard, with some studies reporting greater sleep disturbance for girls (e.g., and others reporting no sex differences in sleep quality (e.g., Lee et al, 1999;Liu & Zhou, 2002).…”

“…Finally, our method of assessing sleep quantity is generally in line with the self-report measures that have been employed in previous studies. Although many (e.g., Lee et al, 1999;) request bedtime and wake-up time hours as opposed to a report of students' hours of sleep on a typical school night, both approaches yield essentially the same information.…”

Sleepless in Chicago: Tracking the Effects of Adolescent Sleep Loss During the Middle School Years

et al. 2004

The influence of the sleep patterns of 2,259 students, aged 11 to 14 years, on trajectories of depressive symptoms, self-esteem, and grades was longitudinally examined using latent growth cross-domain models. Consistent with previous research, sleep decreased over time. Students who obtained less sleep in sixth grade exhibited lower initial self-esteem and grades and higher initial levels of depressive symptoms. Similarly, students who obtained less sleep over time reported heightened levels of depressive symptoms and decreased self-esteem. Sex of the student played a strong role as a predictor of hours of sleep, self-esteem, and grades. This study underscores the role of sleep in predicting adolescents' psychosocial outcomes and highlights the importance of using idiographic methodologies in the study of developmental processes.

DEEP sleep: The impact of sleep on financial risk taking

In this paper, we examine the relationship between sleep and financial risk taking. The results indicate that individuals who have better sleep display less distortion of probability, are less susceptible to the present bias, and have a lower discounting rate. Specifically, individuals with better self‐reported sleep quality have less distortion of probability, a more curved utility function, and are less loss averse, while those with fewer sleep disturbances display less probability distortion and have more curvature in their utility function. Overall, the results show that there are cognitive deficits in financial decision making by having poor sleep habits that can have important consequences.
