What Parents Need to Know About Sleep in Children

Author/s: 
Cynthia-Mae M Hunt, Lindsay A Thompson

Half of all children have sleep issues at some point during childhood.

When a child does not sleep well, the entire family feels the impact. Sleep supports growth and development and prevents other illnesses. Poor sleep can lead to daytime irritability, trouble focusing, behavioral issues, and learning difficulties. Poor sleep is also associated with long-term problems, such as obesity, breathing problems, and heart problems.

Childhood sleep problems fall into 4 main categories. The most common is behavioral insomnia. This happens when a child has trouble falling or staying asleep, often because they need a specific habit or aid (like rocking or feeding) to settle. Without this help, they struggle to soothe themselves to sleep.

A second category is parasomnias, which are sleep disturbances like night terrors, sleepwalking, and teeth grinding. Night terrors are sudden episodes in which a child screams or appears panicked early in the night. While frightening to witness, the child is unaware of the episode and will have no memory of it. These are usually harmless and temporary.

A third category is bed-wetting, which is also common up to around age 7 years and is usually normal. If it continues regularly after that, discuss with a health care professional to rule out underlying issues or find strategies to help.

Sleep apnea is the final category and is a more serious condition involving repeated pauses in breathing during sleep. Sleep apnea can be caused by enlarged tonsils or excess weight. Children may snore loudly, gasp, or appear restless at night. This disrupted sleep can affect their mood, behavior, and ability to learn. Some children may need overnight sleep studies to diagnose sleep apnea and provide interventions to decrease lifetime illness.

Speak to your child’s pediatrician if you have concerns. Note if your child snores loudly 3 or more nights per week, especially if they gasp or choke during sleep. Excessive daytime sleepiness, frequent headaches or stomachaches, or sleep consistently lasting less than the recommended amount (less than 9 hours for school-aged children) are also signs that your child may have a more serious sleep condition.

All sleep problems need attention. The best way to support better sleep is to create consistent routines that support sleep, known as good sleep hygiene. Keep the same bedtime and waking time every day, including weekends. Establish a calm wind-down routine (like a bath or quiet reading) for 20 to 45 minutes before bed. Turn off all screens and end exciting activities at least 1 hour before bedtime, and make sure the bedroom is cool, dark, and quiet without televisions and screens. Pay attention to both nighttime signs (like snoring or waking) and daytime behaviors (like crankiness, trouble concentrating, or hyperactivity). For children who have trouble falling asleep on their own, put them to bed when they are drowsy but still awake so they learn how to independently fall asleep. They will need this skill every time they wake up in the middle of the night, which could happen 2 to 3 times. With consistency, many sleep issues improve, helping your child rest well at night and feel their best during the day.

Effect of Psychological and Medication Therapies for Insomnia on Daytime Functions: A Randomized Clinical Trial

Author/s: 
Charles M Morin, Si-Jing Chen, Hans Ivers, Simon Beaulieu-Bonneau, Andrew D Krystal, Bernard Guay, Lynda Bélanger, Ann Cartwright, Bryan Simmons, Manon Lamy, Mindy Busby, Jack D Edinger

Importance: Daytime functional impairments are the primary reasons for patients with insomnia to seek treatment, yet little is known about what the optimal treatment is for improving daytime functions and how best to proceed with treatment for patients whose insomnia has not remitted.

Objectives: To compare the efficacy of behavioral therapy (BT) and zolpidem as initial therapies for improving daytime functions among patients with insomnia and evaluate the added value of a second treatment for patients whose insomnia has not remitted.

Design, setting, and participants: In this sequential multiple-assignment randomized clinical trial conducted at institutions in Canada and the US, 211 adults with chronic insomnia disorder were enrolled between May 1, 2012, and December 31, 2015, and followed up for 12 months. Statistical analyses were performed on an intention-to-treat basis in April and October 2023.

Interventions: Participants were randomly assigned to either BT or zolpidem as first-stage therapy, and those whose insomnia had not remitted received a second-stage psychological therapy (BT or cognitive therapy) or medication therapy (zolpidem or trazodone).

Main outcomes and measures: Study outcomes were daytime symptoms of insomnia, including mood disturbances, fatigue, functional impairments of insomnia, and scores on the 36-item Short-Form Health Survey (SF-36) physical and mental health components.

Results: Among 211 adults with insomnia (132 women [63%]; mean [SD] age, 45.6 [14.9] years), 104 were allocated to BT and 107 to zolpidem at the first stage. First-stage treatment with BT or zolpidem yielded significant and equivalent benefits for most of the daytime outcomes, including depressive symptoms (Beck Depression Inventory-II mean score change, -3.5 [95% CI, -4.7 to -2.3] vs -4.3 [95% CI, -5.7 to -2.9]), fatigue (Multidimensional Fatigue Inventory mean score change, -4.7 [95% CI, -7.3 to -2.2] vs -5.2 [95% CI, -7.9 to -2.5]), functional impairments (Work and Social Adjustment Scale mean score change, -5.0 [95% CI, -6.7 to -3.3] vs -5.1 [95% CI, -7.2 to -2.9]), and mental health (SF-36 mental health subscale mean score change, 3.5 [95% CI, 1.9-5.1] vs 2.5 [95% CI, 0.4-4.5]), while BT produced larger improvements for anxiety symptoms relative to zolpidem (State-Trait Anxiety Inventory mean score change, -4.1 [95% CI, -5.8 to -2.4] vs -1.2 [95% CI, -3.0 to 0.5]; P = .02; Cohen d = 0.55). Second-stage therapy produced additional improvements for the 2 conditions starting with zolpidem at posttreatment in fatigue (Multidimensional Fatigue Inventory mean score change: zolpidem plus BT, -3.8 [95% CI, -7.1 to -0.4]; zolpidem plus trazodone, -3.7 [95% CI, -6.3 to -1.1]), functional impairments (Work and Social Adjustment Scale mean score change: zolpidem plus BT, -3.7 [95% CI, -6.4 to -1.0]; zolpidem plus trazodone, -3.3 [95% CI, -5.9 to -0.7]) and mental health (SF-36 mental health subscale mean score change: zolpidem plus BT, 5.3 [95% CI, 2.7-7.9]; zolpidem plus trazodone, 2.0 [95% CI, 0.1-4.0]). Treatment benefits achieved at posttreatment were well maintained throughout the 12-month follow-up, and additional improvements were noted for patients receiving the BT treatment sequences.

Conclusions and relevance: In this randomized clinical trial of adults with insomnia disorder, BT and zolpidem produced improvements for various daytime symptoms of insomnia that were no different between treatments. Adding a second treatment offered an added value with further improvements of daytime functions.

Seasonal Affective Disorder

What is seasonal affective disorder?

Many people go through short periods when they feel sad or unlike their usual selves. Sometimes, these mood changes begin and end when the seasons change. Many people feel "down" or have the "winter blues" when the days get shorter in the fall and winter and feel better in the spring when longer daylight hours return.

Sometimes, these mood changes are more serious and can affect how a person feels, thinks, and behaves. If you have noticed significant changes in your mood and behavior when the seasons change, you may be experiencing seasonal affective disorder (SAD).

In most cases, SAD symptoms start in the late fall or early winter and go away during the spring and summer, known as winter-pattern SAD or winter depression. Other people experience depressive symptoms during the spring and summer months, known as summer-pattern SAD or summer depression. Summer-pattern SAD is less common.

Sleep as a vital sign

Author/s: 
Hirschtritt, M.E., Walker, M. P., Krystal, A.D.

Sleep is causally linked to the maintenance of every major physiological body system and disturbed sleep contributes to myriad diseases. The problem is, however, is that patients do not consistently, nor spontaneously, report sleep problems to their clinicians. Compounding the problem, there is no standard-of-care approach to even the most rudimentary of sleep queries. As a result, sleep disturbances remain largely invisible to most clinicians, and consequentially, unaddressed for the patient themselves – thereby exacerbating physical and mental health challenges due to unaddressed sleep problems. In this review, we argue that all patients should be routinely screened with a short, readily available, and validated assessment for sleep disturbances in clinical encounters. If the initial assessment is positive for any subjective sleep-related problems, it should prompt a more thorough investigation for specific sleep disorders. We further describe how a program of short and simple sleep health screening is a viable, efficacious yet currently missing pathway through which clinicians can 1) screen for sleep-related problems, 2) identify patients with sleep disorders, 3) rapidly offer evidence-based treatment, and (if indicated) 4) refer patients with complex presentations to sleep medicine specialists.

Positional Plagiocephaly and Craniosynostosis

Author/s: 
Santiago, G. S., Santiage, C. N., Chwa, E. S., Purnell, C. A.

Along with the decrease in sudden infant death syndrome due to the successful "Back to Sleep" Campaign, there was a reciprocal increase in cases of positional plagiocephaly (PP). The prevalence of PP significantly rose from approximately 5% to upward of 46% at age 7 months. Consequently, clinicians have seen a surge in the number of patients presenting with head shape abnormalities. Not only does this increase in patient volume pose a logistical problem to clinics, but it also poses a potential risk to patients with craniosynostosis, whose head shape anomalies are similar to a "needle in a haystack" of patients with more common PP. This review explores the causes, risk factors, and treatment options of PP and craniosynostosis, along with the differential of head shape anomalies based on phenotypic presentation. In doing so, we hope to provide pediatric care clinicians with the tools necessary to effectively evaluate and manage patients with head shape abnormalities. [Pediatr Ann. 2023;52(1):e10-e17.].

Twenty-Four-Hour Movement Guidelines and Body Weight in Youth

Author/s: 
Zhu, X, Healy, S, Haegele, JA, Patterson, F

Objective

To examine the prevalence of youth meeting the 24-hour healthy movement guidelines (ie, ≥60 minutes of moderate-to-vigorous physical activity, ≤2 hours of screen time, age-appropriate sleep duration), and which combination of meeting these guidelines was most associated with bodyweight status, in a nationally representative US sample.

Study design

Cross-sectional data from the 2016-2017 National Survey of Children's Health were used. A multinomial regression model of body weight status was generated (underweight, overweight, obese vs healthy weight) and then stratified by sex. Analyses were adjusted for potential confounders.

Results

The sample (n = 30 478) was 50.4% female, 52.4% white, and the mean age was 13.85 ± 2.28 years; 15% percent were obese and 15.2% were overweight. Overall, 9.4% met all 3 of the 24-hour healthy movement guidelines, 43.6% met 2, 37.9% met 1, and 9.1% met none. Meeting zero guidelines (vs 3) was associated with the greatest likelihood of overweight (aOR, 1.85; 95% CI, 1.31-2.61), and obesity (aOR, 4.25; 95% CI, 2.87-6.31). Females (aOR, 4.97; 95% CI, 2.59-9.53) had higher odds of obesity than males (aOR, 3.99; 95% CI, 2.49-6.40) when zero (vs 3) guidelines were met. Meeting the moderate-to-vigorous physical activity guideline, either alone or in combination with screen time or sleep duration (vs all 3), was associated with the lowest odds for overweight and obesity in the full sample.

Conclusion

Meeting all movement guidelines was associated with the lowest risk for obesity, particularly in females. Meeting the moderate-to-vigorous physical activity guideline may be a priority to prevent overweight and obesity in youth.
