Prevalence and predictors for postpartum sleep disorders: a nationwide analysis
1Department of Anesthesiology, Perioperative and Pain Medicine, Stanford University School of Medicine, Stanford, CA, USA.
Summary
Postpartum sleep disorders affect 1.9% of women, with insomnia being most common. History of drug abuse, stillbirth, and chronic hypertension increase risk. Depression often co-occurs.
Area of Science:
- Reproductive Health
- Sleep Medicine
- Public Health
Background:
- Postpartum sleep disorders are common but often underdiagnosed.
- Accurate diagnosis and understanding of risk factors are crucial for maternal well-being.
Purpose of the Study:
- To determine the prevalence of postpartum sleep disorders.
- To identify predictors associated with postpartum sleep disorders.
- To examine the comorbidity of postpartum sleep disorders and depression.
Main Methods:
- Retrospective cohort study utilizing the Optum Clinformatics Datamart Database.
- Inclusion of commercially insured women delivering in California between 2011 and 2014.
- Analysis of International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for sleep disorder diagnoses up to 12 months postpartum.
Main Results:
- 1.9% of women received a postpartum sleep disorder diagnosis; insomnia was most prevalent (1.3%).
- Predictors for postpartum sleep disorders included history of drug abuse, stillbirth delivery, and chronic hypertension.
- A comorbid diagnosis of postpartum sleep disorder and depression occurred in 0.6% of women, with drug abuse history and stillbirth delivery being significant predictors.
Conclusions:
- Postpartum sleep disorders are underdiagnosed, with only 2% identified via ICD-9-CM codes in this cohort.
- Insomnia is the most frequent sleep disorder, and approximately one-third of women with a sleep disorder also have depression.
- Further research is recommended to enhance screening and diagnostic accuracy for postpartum sleep disorders.

01:24Substance Use Disorders Affecting Sleep
205
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:13Insufficient Sleep and Sleep Deprivation
190
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:07Narcolepsy
175
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

01:17Sleepwalking and Sleep Talking
256
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

01:18Nightmares and Night Terrors
146
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

01:15REM Sleep Behavior Disorder
323
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
