MedicalResearch.com: What is the background for this study?

Response: Insufficient sleep among children and adolescents is associated with an increased risk for obesity, diabetes, injuries, poor mental health, and attention and behavior problems.

In previous reports, CDC had found that, nationwide, approximately two thirds of U.S. high school students report sleeping <8 hours per night on school nights. CDC conducted this study to provide state-level estimates of short sleep duration on school nights among middle school and high school students using age-specific recommendations from the American Academy of Sleep Medicine (AASM). AASM has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours for optimal health.

 MedicalResearch.com: What is the background for this study? What are the main findings?

Response: No studies to date have examined the association between social media use (e.g., Facebook, Twitter, Instagram) and sleep duration in a representative sample of middle and high school students, who are a vulnerable age group that has reported high levels of social media use and insufficient sleep.

Our findings suggest an important association between the use of social media and short sleep duration among student aged 11-20 years. Using social media for at least one hour per day was associated with short sleep duration in a dose-response manner.    Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Sleep disturbances are reported by cancer patients at a significantly higher rate than in the general population. Among post‐treatment cancer survivors, 23% to 44% experience insomnia symptoms even years after treatment. Sleep disturbances are most commonly treated with medications which many cancer patients are reluctant to add to the large group of medications already prescribed. Furthermore, systematic light exposure intervention is less burdensome than other non‐pharmacologic interventions for sleep disturbance.

In a pilot study, systematic light exposure intervention (i.e., bright white light from a small light source for 30 minutes each morning for 4 weeks) with a mixed group of fatigued cancer survivors was significantly more effective than comparison dim light exposure in improving sleep efficiency (i.e., clinically large effects). Medium to large effect sizes were also seen in self‐reported sleep quality, total sleep time, and wake time. Results support the conclusion that systematic light exposure intervention has considerable promise for reducing negative side effects among cancer survivors.

MedicalResearch.com: What should readers take away from your report?

Response: Resulting improvement in sleep efficiency was sustained to 3 weeks post‐intervention. Moreover, sleep efficiency in thebright light group improved to clinically normal levels on average (>85%) by the end of the intervention; this improvement was observed even 3 weeks afterward. The comparison dim light group remained at low sleep efficiency levels on average for the entire study.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response:Systematic light exposure using bright white light is a low cost and easily disseminable intervention that offers a feasible and potentially effective alternative to improve sleep in cancer survivors, particularly for those who are fatigued. Future large-scale studies are warranted.

MedicalResearch.com: Is there anything else you would like to add?

Response: Lisa M. Wu, Ph.D. was lead author on the manuscript. William H. Redd, Ph.D. at the Icahn School of Medicine of Mount Sinai was the principal investigator of the study itself. This study was conducted at Mount Sinai.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Sleep deprivation can adversely affect health and wellbeing in any patient population.

In pregnancy, adverse outcomes may include preterm birth, longer labor, cesarean birth, and depression.

We found that women with high-risk pregnancies were sleep deprived even prior to hospitalization. Our sample averaged 29 weeks gestation, and half reported getting only between 5 and 6.5 hours of sleep at home before hospital admission. Our sleep hygiene intervention strategies gave them more control over the environment in their hospital room, and they self-reported significantly better sleep than controls. Interestingly, both groups increased their sleep time to almost 7 hours at night, on average, in the hospital before they were discharged home.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The results of this study solidify some well-established data concerning childhood obesity – namely that children who watch more television and have a more sedentary lifestyle are more likely to have an overweight or obese BMI compared with those who are more active. The survey results highlight some associations between increased technology use and difficulty with sleep quantity in children and adolescents.

The data suggest:

  • ​​Increased technology use at bedtime, namely television, cell phones, video games and computers, is associated with a decrease in the amount of sleep children are getting. These children were more likely to be tired in the morning and less likely to eat breakfast.
  • Specifically, children who reported watching TV or playing video games before bed got an average of 30 minutes less sleep than those who did not, while kids who used their phone or a computer before bed averaged an hour less of sleep than those who did not.
  • The data also suggests that children with overweight or obesity were more likely to have trouble falling asleep and trouble staying asleep than their normal BMI counterparts
  • When children were reported by their parents to use one form of technology at bedtime, they were more likely to use another form of technology as well.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The Data Registry on Experiences of Aging, Menopause and Sexuality (DREAMS) was used for this study investigating the association between vasomotor symptoms (hot flashes and night sweats) and risk for obstructive sleep apnea, a common and underdiagnosed sleep disorder in women which is associated with increased cardiovascular risk.

We found that Women who had severe or very severe hot flashes or night sweats were more likely to be at increased risk for obstructive sleep apnea.  This association held even after adjusting for age, body mass index, smoking and hypertension, such that the odds of women having intermediate /high risk for obstructive sleep apnea were 1.87 times higher for those with severe/very severe hot flashes/night sweats compared to those with less severe symptoms.  We decided to analyze the group of women with normal body mass index, and indeed, this finding was still significant in the lean group of women.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Around one third of the world’s population suffers from insomnia. Previous studies showed that sleep disorders affect the hypothalamic–pituitary–adrenal axis and the sympatho-adrenal system, which may cause abnormalities in several organ systems and pathways causing metabolic or cardiovascular abnormalities. However, there is inadequate evidence of an association between chronic insomnia and adverse renal outcomes.

After examining 938,473 US veterans (4.4% of them had chronic insomnia) with baseline estimated eGFR >60 ml/min/1.73m2, we found that chronic insomnia is associated with a 43% higher risk of all-cause mortality, a 2.5-fold higher incidence of eGFR ≤45ml/min/1.73m2, a 2.3-fold higher ESRD risk, and with rapid loss of kidney function.

Starting School Before 8:30 AM Associated With More Anxiety and Depression in Adolescents

MedicalResearch.com Interview with:
Jack Peltz, Ph.D.

Clinical assistant professor in Psychiatry
Rochester Medical Center

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Approximately 90% of high-school aged adolescents get either
insufficient sleep during school nights or barely meet the required
amount of sleep (ie, 8–10 hours) expected for healthy functioning.(1)

In fact, sleep problems and insufficient sleep are so pervasive for
adolescents that they could be considered an epidemic due to their
adverse impact on adolescent mental and physical health.(2–5)

As a result,addressing insufficient adolescent sleep represents a critical
point of study and intervention. The growing body of evidence suggests
that later school start times (SST), 8:30 AM or later as recommended
by the American Academy of Pediatricians,6 convey
multiple benefits on adolescents, including improved sleep, better
mental and physical health, and improved academic outcomes.(7–10)

This research, however, has focused on the direct effects of delaying
school start times, or specifically how moving SST back directly predicts changes
in an outcome (eg, mental health, academic achievement). This
type of analysis precludes examining the important role that SST
might play as a condition or context under which other sleeprelated
processes take place. For instance, earlier school start times might exacerbate
the impact of sleep-related processes on adolescent behavioral
health outcomes. Thus, incorporating school start times as a larger contextual variable
that might moderate models of sleep and adolescent functioning
represents a gap in the literature and a unique opportunity to advance
conceptual models. Accordingly, the current study examines
the moderating role of school start times on the associations between sleep hygiene,
sleep quality, and mental health.

MedicalResearch.com: Why did you conduct this study?

Response: Our research focuses on the health of women as they age and transition from the childbearing period. During this time, women may be at increased risk for chronic health conditions such as diabetes and cardiovascular disease.

As insufficient sleep is a modifiable behavior that is associated with these chronic health conditions, we wanted to examine how sleep duration and quality varies by menopausal status.
