“…A similar finding has been observed in obese and nonobese children at ages 0.1-6.9 years (5). Also, total sleep duration declines rapidly in the first decade of life (2,7,23) and blood pressure also increases with progressive age in childhood (5,13); in the present study, however, age was not significantly related to SBP or DBP because of the small range of age. In addition, blood pressure and sleep duration may be affected by various factors -daily activities and diets or nocturnal urinary behavior (9) -other than age and BMI in preschool children, though it was impossible to examine all of such factors.…”

The onset of some adult diseases, e.g., cardiovascular disease, is known to be associated with lifestyles in childhood. The objective of this study was to clarify the relationship between total sleep duration (TSD) and systolic and diastolic blood pressure (SBP and DBP) among 117 children at ages 5-6 years. Parents reported their children's typical bedtimes and wake times for weekdays, and questions about mandatory nap times were answered by the preschool teachers. In the children, the mean TSD, SBP, and DBP were 624 ± 57 (standard deviation) min, 99 ± 10 mmHg, and 62 ± 9 mmHg, respectively. When the children were divided into quartile groups based on TSD, the SBP was significantly higher in the highest group (TSD > 660 min) than in the lowest group (TSD ≤ 585 min). The TSD was significantly correlated with SBP (r = 0.265) but not with DBP (r = 0.105), these relationships were similar when TSD and possible confounders such as age and body mass index were set as independent variables of multiple regression analysis. These findings suggest that sleep duration in preschool children is associated with SBP, and extremely short or long sleep may invite subclinical health problems.

“…Such changes in the HRV parameters and SBP may lead to dysautonomia or hypotension in the near future, inasmuch as the sympathovagal balance does not seem to have been affected by nocturnal sleep duration. In addition, no HRV parameters in our preschool children aged 5-6 years were influenced by age or sex, while the CCV HF and CCV LF are considered to decrease with progressive age (Murata et al 1992;Tanaka et al 2000;Antelmi et al 2004); it may imply that the decreasing HRV in childhood is controlled more strongly by nocturnal sleep duration than by age, because sleep duration reduces in childhood (Thorleifsdottir et al 2002;Iglowstein et al 2003;Crosby et al 2005;Ishihara 2005;Ng et al 2005). Thus, sleep duration is suggested to be an important predictor for autonomic development in childhood.…”

“…In spite of potential issues involved in the estimation of nocturnal sleep (Sekine et al 2002), the duration between bedtime and wake time for weekdays in preschool children aged 5 to 6 years has been reported to be 10-11 hrs in Iceland (Thorleifsdottir et al 2002), about 11 hrs in Switzerland (Iglowstein et al 2003), and 9.7-10.2 hrs in the U.S. (Crosby et al 2005), while sleep durations in Hong Kong and Japan seem to be somewhat short (Ishihara 2005;Ng et al 2005). Judging from these data, it could be hypothesized that the optimal duration of nocturnal sleep for preschool children is 10 hrs or more.…”

Preschool children with sleep deficit may suffer from autonomic symptoms or hypotension. Heart rate variability, reflecting cardiac parasympathetic and sympathetic activities, and blood pressure were assessed to clarify the effects of nocturnal sleep duration on cardiac autonomic function in 134 preschool children aged 5 and 6 years. Parents reported their children's typical bedtimes and wake times for weekdays. In the children, the mean nocturnal sleep duration (± standard deviation) was 575 ± 42 min. The parasympathetic and sympathetic activities and systolic blood pressure (SBP) were significantly lower in the 80 children with short sleep (nocturnal sleep duration < 10 hrs) than in the 54 children with long sleep ( 10 hrs). Only the SBP was positively correlated with nocturnal sleep duration in the children ( p < 0.001); also, short nocturnal sleep duration was significantly related to hypotension (SBP < 100 mmHg), as judged by multiple logistic regression analysis. Among the children, inverse correlations were seen between the parasympathetic activity and SBP and between the sympathetic activity and diastolic blood pressure ( p < 0.05). These findings indicate that shortening of nocturnal sleep is associated with cardiac autonomic hypofunction and low SBP in preschool children. We suggest that sleep duration is an important predictor for autonomic development in childhood.nocturnal sleep duration; cardiac parasympathetic and sympathetic activities; blood pressure; preschool children

“…"Catching up" on sleep on the weekends is seen as indirect evidence of sleep deprivation (Crosby, LeBourgeois, & Harsh, 2005), and is associated with impaired daytime functioning (i.e., driving drowsy or reduced work productivity; NSF, 2008;Wolfson & Carskadon, 1998), greater anxiety, depression, and low self-esteem (El-Sheik, Kelly, Buckhalt, & Hinnant, 2010), as well as circadian desynchronization (Dollander, 2002). Thus, daytime sleepiness and weekend oversleep provide additional insight into how sleep schedule, nocturnal sleep, or lack thereof, may influence overall daytime functioning and well-being (Dean et al, 2010;Drake et al, 2010;Drake et al, 2004;Pallesen et al, 2007;Ursin et al, 2005).…”

Socioeconomic gradients exist for multiple health outcomes. Lower objective socioeconomic position (SEP), whether measured by income, education, or occupation, is associated with inadequate sleep. Less is known about whether one's perceived ranking of their social status, or subjective SEP, affects sleep. This study examined whether a subjective socioeconomic gradient exists for sleep while controlling for objective SEP. Participants (N = 177; age, M = 45.3 years, SD = 6.3 years) completed the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, MacArthur Ladder, and other self-report measures to assess sleep and objective SEP. Subjective SEP trumped objective SEP as a better predictor of sleep duration, daytime sleepiness, and weekend oversleep. These findings highlight the need to expand our framework to better understand the mechanisms underlying socioeconomic gradients and sleep.It is well established that a socioeconomic gradient exists for multiple health outcomes, even after adjusting for known risk factors. Adults of lower socioeconomic position (SEP) report more frequent acute and chronic physical (e.g., insomnia) and mental problems (e.g., depression), as well as poorer quality of life, compared to adults of higher SEP (Adler et al
