GERD and Sleep Disorders Often Go Hand in Glove

DENVER – Gastroesophageal reflux disease is fertile soil for medical and psychiatric comorbid conditions, with sleep disorders leading the way, Maurice M. Ohayon, MD, reported at the annual meeting of the Associated Professional Sleep Societies.

He presented a very large, longitudinal, population-based study of gastroesophageal reflux disease (GERD) and its fellow travelers. The study entailed telephone interviews with 12,218 nationally representative subjects in 8 states at time 1, and reinterviews with 10,830 of them 3 years later. The interviews were guided by Sleep-EVAL, a validated computerized diagnostic interview system.

At time 1, 10.6% of subjects reported that they were told by a physician they have GERD and/or they were taking a medication for it. At time 2 (3 years later), the prevalence had increased to 12.4%, according to Dr. Ohayon, professor of psychiatry and behavioral sciences, chief of the division of public mental health and population sciences, and director of the sleep epidemiology research center at Stanford (Calif.) University.

Chronic GERD – that is, GERD at both time points – was present in 3.9% of subjects; 6% of subjects were remitters, meaning that they had GERD at time 1 but not at time 2. Another 8.5% of the total sample had incident GERD, meaning they had GERD at time 2 but not time 1.

The prevalence of GERD rose stepwise with increasing age, from the low single digits in 18- to 34-year-olds to a peak in the 55- to 64-year-old age group, where the prevalence was 13.5% at time 1 and 17% at time 2.

GERD was significantly more common in women. At time 2, the prevalence was 10% in men and 14.4% in women.

Nocturnal awakening was the sleep disorder symptom most commonly associated with GERD. It was a complaint in 28% of subjects who never had GERD, 46% of those with GERD at time 1, and 40% of those with GERD at time 2.

Insomnia, obstructive sleep apnea, and restless legs syndrome were also significantly more common among subjects with GERD. So were musculoskeletal and connective tissue diseases, hypertension, hypercholesterolemia, and major depressive disorder.

The study was supported by the John Arrillaga Foundation and Takeda Pharmaceuticals. Dr. Ohayon reported no financial conflicts of interest.

Expert: Screen military spouses for sleep problems

DENVER – Sleep problems and their host of deleterious physical and psychosocial consequences are pervasive among the civilian female spouses of U.S. military service members, according to the first large study to examine the issue.

“Our findings suggest that if we’re trying to promote the resilience and adjustment of military spouses and their families – particularly in light of 14 years of protracted overseas combat, where many families are experiencing deployment – sleep might be a really important target,” Wendy M. Troxel, PhD, said while presenting the study results at the annual meeting of the Associated Professional Sleep Societies.

The study population consisted of a nationally representative group of 1,805 female civilian spouses of military service members. Forty-four percent reported short sleep duration, meaning 6 hours or less per night. Another 18% got 5 hours or less. The Centers for Disease Control and Prevention and the American Academy of Sleep Medicine recommend 7 hours or more, noted Dr. Troxel, senior behavioral and social scientist at RAND Corporation in Pittsburgh.

More than half (54%) of military spouses reported that their sleep problems contributed to daytime impairment, such as intolerance of their spouse or children, frequent crying, or suboptimal performance at work or chores. One-third of the spouses reported feeling daytime fatigue three or more times per week, and another 29% experienced daytime fatigue one or two days per week.

As has been observed in other studies, sleep problems in military spouses were associated with psychosocial impairment. In linear regression analyses, the spouses with poor sleep quality, daytime impairment, and/or fatigue had significantly more depressive symptoms on the Patient Health Questionnaire–8, lower marital satisfaction, and poor self-rated health. Women with shorter sleep duration had more depressive symptoms and poorer self-rated health, but not lower marital satisfaction.

The spouses of services members currently deployed in combat zones had significantly worse sleep quality as measured on the Pittsburgh Sleep Quality Index compared with spouses of previously or never-deployed service members. But for the other outcomes of interest – sleep duration, daytime impairment, and fatigue – there were no differences based upon deployment status.

“This shows that it’s not just about the stress of combat deployment, it’s also about the stresses of everyday military life. Military families experience a great deal of stress that could lead to sleep disturbances whether or not a service member has been deployed: frequent residential moves, very long and unpredictable work hours, demanding jobs, threatening training environments,” Dr. Troxel said. “I think we need to be thinking about sleep as an important health indicator of military families in general across the deployment cycle.”

The study results are a call to action, she added.

“These findings highlight the importance of targeted screening, prevention, and intervention methods for military spouses. And primary care is where most people present with sleep problems,” Dr. Troxel said.

There are formal screening instruments for sleep problems, but in her view they really need to be better validated for use in primary care before widespread adoption.

“Simply having providers ask three quick questions about their patients’ sleep and daytime function is a good, practical approach: How’s the quality of your sleep? How much do you sleep on average? Do you have enough energy during the daytime to get through your day-to-day functioning? That’s informative enough to indicate the utility of moving on to longer screening tools or to referral for evidence-based treatments,” she said.

Dr. Troxel noted successful intervention in sleep problems in civilian spouses is a priority for reasons beyond their personal well-being. “Civilian spouses are most often the primary caretakers for service members who return from war with either invisible mental health wounds or physical health wounds,” she said. “And we’re expecting to have need for a lot of caretakers.”

The RAND National Defense Research Institute, the Office of the Surgeon General, the U.S. Army, and the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury funded the study.

Sleep apnea in pregnancy linked to preterm birth

Sleep apnea in pregnancy linked to preterm birth

DENVER – Pregnant women with sleep apnea are more likely to have planned obstetric interventions, results of an Australian population-based cohort study suggest.

The study included all 636,227 in-hospital births during 2002-2012 in New South Wales, Australia’s most populous state. Maternal sleep apnea was also associated with increased rates of planned preterm birth, even though preterm birth is widely considered the greatest contributor to neonatal morbidity and mortality, Yu Sun Bin, PhD, said at the annual meeting of the Associated Professional Sleep Societies.

Bruce Jancin/Frontline Medical News

“Somewhere along the line, clinicians decided that the risks of preterm birth to the baby were outweighed by the risks to the mother of delivering at term,” said Dr. Bin of the University of Sydney.

She and her coinvestigators undertook this study because even though previous studies have linked maternal sleep apnea to increased risks of gestational diabetes and gestational hypertension, most of the prior studies were small, cross-sectional, and/or relied upon snoring as a proxy for sleep apnea, which many sleep specialists consider invalid.

The investigators compared maternal and infant outcomes for mothers with a documented diagnosis of sleep apnea – either central or obstructive – in the year before or during pregnancy with outcomes for mothers without that diagnosis.

There were 519 mothers with diagnosed sleep apnea, for a prevalence of 0.08%. That figure is low in light of other evidence, making it likely that the 635,708 women in the no-sleep-apnea group actually included a substantial number of mothers with undiagnosed sleep apnea. Thus, the investigators’ estimates of the adverse impacts of sleep apnea in pregnancy are “rather conservative,” according to Dr. Bin.

Australian women with sleep apnea were older and less healthy than mothers without sleep apnea were. They had higher baseline rates of obesity, preexisting diabetes, chronic hypertension, and were more likely to be smokers.

The incidence of pregnancy hypertension was 19.7% in the sleep apnea group and 8.7% in controls. In a multivariate regression analysis adjusted for potential confounders, the maternal sleep apnea group had a 40% greater risk of developing hypertension than did controls. However, contrary to previous smaller studies, they did not have a significantly increased rate of gestational diabetes.

Even after controlling for both pregnancy hypertension and gestational diabetes, the sleep apnea group still had a significant 15% increase in the relative likelihood of a planned delivery.

The rate of preterm birth at 36 weeks or earlier was 14.5% in the maternal sleep apnea group, compared with 6.9% in controls, for an adjusted 1.5-fold increased relative risk.

Perinatal death occurred in 1.9% of the sleep apnea group and 0.9% of controls; however, the resultant adjusted 1.73-fold increased risk didn’t attain statistical significance because of the small number of deaths in the study. Dr. Bin said she and her colleagues plan to further investigate this signal to learn whether it is real or an artifact of small numbers.

The incidence of 5-minute Apgar scores below 7 was 4.6% in the sleep apnea group, compared with 2.4% in controls, for an adjusted 1.6-fold increased risk. The rate of neonatal intensive care unit admission in the sleep apnea group was 27.9%, versus 16% in controls, for a 1.61-fold increased relative risk.

The NICU admission rate for preterm infants didn’t differ between the two groups. The difference occurred in term babies, whose NICU admission rate was 20.3% if they were in the sleep apnea group, but just 12.1% in the control group.

“This suggests that maternal sleep apnea is contributing to some condition in the baby that requires additional support,” Dr. Bin observed.

The nature of that condition, however, remains unclear, since all patient data available to the investigators was deidentified.

The incidence of small-for-gestational-age babies was similar in the sleep apnea and control groups. In contrast, the large-for-gestational-age rate was 15.2% in the sleep apnea group, compared with 9.1% in controls, for an adjusted 1.27-fold increased risk.

The two main limitations of the Australian study were the likely underdiagnosis of sleep apnea and the lack of any information on treatment of affected patients, according to Dr. Bin. A key unresolved question, she added, is whether interventions for maternal sleep apnea reduce the risks identified in the New South Wales study. She noted that one 16-patient randomized study of nasal continuous positive airway pressure suggests the answer is yes (Sleep Med. 2007 Dec;9:15-21).

The Australian National Health and Medical Research Council supported the study. Dr. Bin reported having no financial conflicts.

DENVER – Pregnant women with sleep apnea are more likely to have planned obstetric interventions, results of an Australian population-based cohort study suggest.

The study included all 636,227 in-hospital births during 2002-2012 in New South Wales, Australia’s most populous state. Maternal sleep apnea was also associated with increased rates of planned preterm birth, even though preterm birth is widely considered the greatest contributor to neonatal morbidity and mortality, Yu Sun Bin, PhD, said at the annual meeting of the Associated Professional Sleep Societies.

“Somewhere along the line, clinicians decided that the risks of preterm birth to the baby were outweighed by the risks to the mother of delivering at term,” said Dr. Bin of the University of Sydney.

She and her coinvestigators undertook this study because even though previous studies have linked maternal sleep apnea to increased risks of gestational diabetes and gestational hypertension, most of the prior studies were small, cross-sectional, and/or relied upon snoring as a proxy for sleep apnea, which many sleep specialists consider invalid.

The investigators compared maternal and infant outcomes for mothers with a documented diagnosis of sleep apnea – either central or obstructive – in the year before or during pregnancy with outcomes for mothers without that diagnosis.

There were 519 mothers with diagnosed sleep apnea, for a prevalence of 0.08%. That figure is low in light of other evidence, making it likely that the 635,708 women in the no-sleep-apnea group actually included a substantial number of mothers with undiagnosed sleep apnea. Thus, the investigators’ estimates of the adverse impacts of sleep apnea in pregnancy are “rather conservative,” according to Dr. Bin.

Australian women with sleep apnea were older and less healthy than mothers without sleep apnea were. They had higher baseline rates of obesity, preexisting diabetes, chronic hypertension, and were more likely to be smokers.

The incidence of pregnancy hypertension was 19.7% in the sleep apnea group and 8.7% in controls. In a multivariate regression analysis adjusted for potential confounders, the maternal sleep apnea group had a 40% greater risk of developing hypertension than did controls. However, contrary to previous smaller studies, they did not have a significantly increased rate of gestational diabetes.

Even after controlling for both pregnancy hypertension and gestational diabetes, the sleep apnea group still had a significant 15% increase in the relative likelihood of a planned delivery.

The rate of preterm birth at 36 weeks or earlier was 14.5% in the maternal sleep apnea group, compared with 6.9% in controls, for an adjusted 1.5-fold increased relative risk.

Perinatal death occurred in 1.9% of the sleep apnea group and 0.9% of controls; however, the resultant adjusted 1.73-fold increased risk didn’t attain statistical significance because of the small number of deaths in the study. Dr. Bin said she and her colleagues plan to further investigate this signal to learn whether it is real or an artifact of small numbers.

The incidence of 5-minute Apgar scores below 7 was 4.6% in the sleep apnea group, compared with 2.4% in controls, for an adjusted 1.6-fold increased risk. The rate of neonatal intensive care unit admission in the sleep apnea group was 27.9%, versus 16% in controls, for a 1.61-fold increased relative risk.

The NICU admission rate for preterm infants didn’t differ between the two groups. The difference occurred in term babies, whose NICU admission rate was 20.3% if they were in the sleep apnea group, but just 12.1% in the control group.

Insomnia severity more pronounced in older Hispanics

Insomnia is a more pronounced problem than expected among Hispanics over age 50, according to results of a study by Christopher N. Kaufmann, PhD, and his coauthors.

Dr. Kaufmann and his colleagues studied 22,252 participants of white, Non-Hispanic black, Hispanic, or other race/ethnicity. Participant data came from a nationally representative survey from 2002 to 2010, in which patients rated the severity of four insomnia symptoms. All participants were adults older than 50 years.

Insomnia severity scores increased 0.19 points over time after the investigators controlled for sex, race/ethnicity, education, and baseline age (95% CI, 0.14-0.24; t = 7.52; design df = 56; P less than .001). After adjustment for accumulated health conditions and body mass index, this trend decreased, Dr. Kaufmann and his colleagues added. However, the increasing trajectory of insomnia severity was “significantly more pronounced” among Hispanics, compared with non-Hispanic whites, after adjustment for accumulated health conditions, body mass index, and number of depressive symptoms, the investigators said in the report.

Although health conditions can result in greater insomnia severity with age, “further research is needed to determine the reasons for a different insomnia trajectory among Hispanics,” the authors concluded.

Insomnia in Young Men Boosts Cardiovascular and Cerebrovascular Risk

Insomnia in Young Men Boosts Cardiovascular and Cerebrovascular Risk

DENVER – Young to early middle-aged men with insomnia symptoms are at increased risk for cardiovascular and cerebrovascular events, according to an analysis from the landmark CARDIA study.

“We found that younger to mid-life men with difficulty initiating sleep or with more than one insomnia symptom were at greater risk for incident cardiovascular disease events. And despite the fact that women in general seemed to be more prone to report those sleep difficulties, those that did were not at increased risk,” Megan E. Petrov, PhD, reported at the annual meeting of the Associated Professional Sleep Societies.

It is well established that insomnia in older adults is associated with increased cardiovascular risk. For example, a meta-analysis of 13 prospective studies with more than 123,000 subjects concluded that insomnia was associated with a 45% increased risk of fatal and nonfatal cardiovascular events (Eur J Prev Cardiol. 2014 Jan;21[1]:57-64). But those studies typically involved older individuals, which makes cause and effect more difficult to determine because so many chronic conditions become more prevalent with advancing age, noted Dr. Petrov of Arizona State University in Phoenix.

“We wanted to see if insomnia is truly an early risk factor in the pathogenesis of cardiovascular disease and stroke,” she said.

To do so, she and her coinvestigators turned to the CARDIA database. CARDIA (the Coronary Artery Risk Development in Young Adults study), is a National Heart, Lung, and Blood Institute–sponsored prospective, epidemiologic study.

She reported on 2,950 non-Hispanic black or white participants aged 33-45 and free of any history of cardiovascular disease in 2000-2001, when they answered questions about insomnia symptoms. Difficulty in initiating sleep was reported by 16.3% of men and 20.7% of women. Difficulty maintaining sleep was a problem for 9.3% of men and 14.5% of women. And 20.6% of men and 20.1% of women reported frequent early morning awakening.

During a mean 11.5 years of prospective follow-up, 4.1% of men and 2.3% of women had a fatal or nonfatal MI, stroke, transient ischemic attack, heart failure, peripheral vascular disease, or hospitalization for an acute coronary syndrome.

In a multivariate logistic regression analysis fully adjusted for demographics, socioeconomic status, body mass index, blood pressure, diabetes, depression, health behaviors, medications, thyroid disease, and kidney problems, men who reported difficulty in getting to sleep had a 2.64-fold increased risk of one of these adverse outcomes. That was the only insomnia symptom associated with significantly increased risk. However, men but not women who reported having more than one insomnia symptom had a 39% increased risk of a cardiovascular event for each additional symptom.

Prior studies have shown that insomnia is associated with cardiac sympathetic hyperactivation. That observation suggests a plausible mechanism for increased cardiovascular and cerebrovascular risk, but it doesn’t explain why that risk was confined to young men in CARDIA. One possibility is that because of gender-related differences in perception, men tend to report having insomnia symptoms only when the insomnia is more severe, Dr. Petrov suggested.

The strengths of the CARDIA study are that all cardiovascular endpoints had to be physician certified, and the study includes a large black population. A study limitation is the relatively small number of cardiovascular events, as to be expected in a younger population. Thus, confirmation of the new findings in another large data set will be important, she noted.

As a next step in her research, Dr. Petrov said she plans to drill down in the CARDIA data to see if race modified the impact of insomnia symptoms on cardiovascular outcomes. Black participants reported all insomnia symptoms more frequently than did whites. For example, difficulty initiating sleep was reported by 25.7% of blacks, compared with just 13.5% of whites, and early morning awakening was twice as prevalent among the black participants.

Also, CARDIA participants provided self-reported sleep duration data. It will be illuminating to see if sleep duration had a modifying effect upon the insomnia/cardiovascular risk association observed in men, she said.

Dr. Petrov reported having no relevant financial conflicts.

And despite the fact that women in general seemed to be more prone to report those sleep difficulties, those that did were not at increased risk,” Megan E. Petrov, PhD, reported at the annual meeting of the Associated Professional Sleep Societies.

It is well established that insomnia in older adults is associated with increased cardiovascular risk. For example, a meta-analysis of 13 prospective studies with more than 123,000 subjects concluded that insomnia was associated with a 45% increased risk of fatal and nonfatal cardiovascular events (Eur J Prev Cardiol. 2014 Jan;21[1]:57-64). But those studies typically involved older individuals, which makes cause and effect more difficult to determine because so many chronic conditions become more prevalent with advancing age, noted Dr. Petrov of Arizona State University in Phoenix.

“We wanted to see if insomnia is truly an early risk factor in the pathogenesis of cardiovascular disease and stroke,” she said.

To do so, she and her coinvestigators turned to the CARDIA database. CARDIA (the Coronary Artery Risk Development in Young Adults study), is a National Heart, Lung, and Blood Institute–sponsored prospective, epidemiologic study.

She reported on 2,950 non-Hispanic black or white participants aged 33-45 and free of any history of cardiovascular disease in 2000-2001, when they answered questions about insomnia symptoms. Difficulty in initiating sleep was reported by 16.3% of men and 20.7% of women. Difficulty maintaining sleep was a problem for 9.3% of men and 14.5% of women. And 20.6% of men and 20.1% of women reported frequent early morning awakening.

During a mean 11.5 years of prospective follow-up, 4.1% of men and 2.3% of women had a fatal or nonfatal MI, stroke, transient ischemic attack, heart failure, peripheral vascular disease, or hospitalization for an acute coronary syndrome.

In a multivariate logistic regression analysis fully adjusted for demographics, socioeconomic status, body mass index, blood pressure, diabetes, depression, health behaviors, medications, thyroid disease, and kidney problems, men who reported difficulty in getting to sleep had a 2.64-fold increased risk of one of these adverse outcomes. That was the only insomnia symptom associated with significantly increased risk. However, men but not women who reported having more than one insomnia symptom had a 39% increased risk of a cardiovascular event for each additional symptom.

Prior studies have shown that insomnia is associated with cardiac sympathetic hyperactivation. That observation suggests a plausible mechanism for increased cardiovascular and cerebrovascular risk, but it doesn’t explain why that risk was confined to young men in CARDIA. One possibility is that because of gender-related differences in perception, men tend to report having insomnia symptoms only when the insomnia is more severe, Dr. Petrov suggested.

The strengths of the CARDIA study are that all cardiovascular endpoints had to be physician certified, and the study includes a large black population. A study limitation is the relatively small number of cardiovascular events, as to be expected in a younger population. Thus, confirmation of the new findings in another large data set will be important, she noted.

As a next step in her research, Dr. Petrov said she plans to drill down in the CARDIA data to see if race modified the impact of insomnia symptoms on cardiovascular outcomes. Black participants reported all insomnia symptoms more frequently than did whites. For example, difficulty initiating sleep was reported by 25.7% of blacks, compared with just 13.5% of whites, and early morning awakening was twice as prevalent among the black participants.

Also, CARDIA participants provided self-reported sleep duration data. It will be illuminating to see if sleep duration had a modifying effect upon the insomnia/cardiovascular risk association observed in men, she said.

Dr. Petrov reported having no relevant financial conflicts.

Restless Sleep in 11-year-olds Predicts Earlier Substance Use

DENVER – Poor sleep quality and shorter sleep duration in boys at age 11 years is associated with subsequent accelerated use and misuse of alcohol and cannabis during adolescence and emerging adulthood, Thomas B. Mike reported at the annual meeting of the Associated Professional Sleep Societies.

This association has been reported before in cross-sectional studies. But Mr. Mike presented new findings from the longitudinal prospective Pitt Mother and Child Project.

The study comprised 170 boys aged 11 years whose mothers filled out the Child Sleep Questionnaire, modified for pediatric use from the well known Pittsburgh Sleep Quality Index. At that time, the boys also were assessed for internalizing and externalizing behaviors, neighborhood dangerousness, and socioeconomic status – all of which are factors known to influence teen substance use.

When participants reached ages 20 and 22 years, they underwent detailed interviews including assessment via the validated Lifetime Drinking History and Lifetime Drug History questionnaires.

In a multivariate Cox regression analysis controlling for a history of child internalizing and externalizing problem behavior as well as socioeconomic factors, every hour of sleep duration less than 9.5 hours at age 11 years was associated with a 21% acceleration in the time to first use of alcohol and a 22% acceleration in first use of cannabis, reported Mr. Mike, a medical student at the University of Pittsburgh.

Moreover, every 1 point worse score for sleep quality on the Child Sleep Questionnaire, scored from 0 (best) to 21 (worst), was associated with a 9% acceleration in time to alcohol use and an 8% acceleration to cannabis use.

Subjects with poor sleep duration and quality as 11-year-olds by parental report also experienced intoxication at a younger age than did those who had been better sleepers at that age. And they reported more frequent use of alcohol and cannabis during adolescence.

In an interview, Mr. Mike, who is planning a career in pediatrics, said the study findings contain an important message for pediatricians and family physicians when they meet with the parents of young boys entering adolescence.

“Probably the biggest take-home message is, ‘sleep more, sleep better.’ We don’t have a lot of ways to intervene right now for kids who have poor sleep, but we know based on this and other studies that kids who don’t sleep enough are more likely to use drugs and more likely to engage in other risky behaviors. So any way the parents can intervene will help, perhaps by getting them to bed earlier or trying to get them on a more regular schedule. At a social policy level, having school start later would probably be the most effective measure, but that probably won’t happen for a very long time,” he said.

“The vast majority of people who end up addicted to drugs later in life started when they were kids, so any way we can reduce adolescent substance use should have a downstream effect, including a decreased total substance use burden,” Mr. Mike added.

Possible mechanisms for the observed longitudinal association between poor quality and duration of sleep at age 11 years and earlier and heavier use of alcohol and cannabis later in adolescence include attempted self-medication for sleep problems, reward regulation, and alterations in brain chemistry, making the boys more susceptible to using drugs later in life, perhaps because they obtain a bigger high than their peers do. The investigators plan to delve deeper into the role of self-regulation and mental health as possible mechanisms linking childhood sleep and later substance use, he said.

Women’s Health Initiative May Account for Insomnia’s Upward Trend

DENVER – Much of the rising prevalence of insomnia among U.S. and Canadian adults may be driven by the sharp reduction in the use of hormone replacement therapy following the 2002 report from the Women’s Health Initiative, Sheila N. Garland, PhD, said at the annual meeting of the Associated Professional Sleep Societies.

“In 2002 the Women’s Health Initiative came out with findings that hormone replacement therapy increased the risk of coronary heart disease, breast cancer, stroke, and pulmonary embolism [JAMA. 2002 Jul 17;288(3):321-33]. A lot of women on hormone replacement therapy up until 2002 stopped using it then. The increase in difficulty sleeping we found between 2002 and 2012 could perhaps represent an untreated menopausal symptom,” according to Dr. Garland, a psychologist at Memorial University of Newfoundland in St. John’s.

She presented an analysis of data from the Canadian Community Health Survey, a national once-per-decade survey, which included 34,118 adults aged 20-80 years and older in the 2002 version and 23,089 in 2012.

The key finding from the standpoint of sleep medicine, the prevalence of self-reported trouble sleeping, increased from 15.6% in 2002 to 17.1% in 2012. And this increase was concentrated in 40- to 59-year-old women, where the prevalence of insomnia or poor sleep rose from 19% to 24.3%, the highest of any age group. Rates remained flat over time in men and women aged 20-39 years and 60-80 years and older as well as in 40- to 59-year-old men.

The sleep-related question put to survey participants in face-to-face or telephone interviews was this: “How often do you have trouble going to sleep or staying asleep?” If they answered “most of the time” or “all of the time” they were classified as having poor sleep.

When Dr. Garland saw the survey results she immediately asked herself, “What is happening with Canadian women?” She came up with two theories. They are not mutually exclusive. One hinges on the dramatic drop off in the use of hormone replacement therapy in response to the Women’s Health Initiative report. The other theory is that the increasing prevalence of insomnia in middle-aged women is a manifestation of stress among the growing population of what has been called “the sandwich generation,” people who care for their aging parents while also supporting their own children. Those responsibilities most often fall upon the mother.

She noted that a similar rise in the prevalence of insomnia or trouble sleeping is occurring south of the border – in the United States – as documented in a Centers for Disease Control and Prevention analysis. The CDC investigators examined data on 30,970 adult participants in the 2002 National Health Interview Survey, 23,344 in the 2007 survey, and 34,509 in the 2012 survey. The prevalence of insomnia or trouble sleeping increased from 17.5% in 2002 to 19.2% in 2012. That absolute 1.7% increase pairs well with the 1.5% rise over the same time frame in the Canadian survey. The prevalence was higher in U.S. women than men in all three survey years (Sleep Med. 2015 Mar;16[3]:372-8).

Dr. Garland said the Canadian national survey contains data on self-perceived stress levels. She plans to analyze those results to learn if being a member of the sandwich generation is a significant contributor to poor sleep.

Regardless of the underlying mechanism, she continued, it’s clear from these large national surveys that middle-aged women are particularly vulnerable to poor sleep.

“Increased recognition is necessary. Prevention and intervention programs may be warranted, given the individual and societal consequences of poor sleep, including increased psychiatric and medical disorders, work absenteeism, and health care costs,” she said.

One audience member rose to congratulate Dr. Garland on her detective work. He commented that her notion that the rise in insomnia can be traced to fallout from the 2002 Women’s Health Initiative is consistent with his own clinical experience.

“The most common way women over age 40 present to our sleep center with insomnia is because they’re menopausal and not on hormone replacement therapy,” he said.

The Canadian Community Health Survey is sponsored by Statistics Canada. Dr. Garland reported having no financial conflicts of interest.

DENVER – Much of the rising prevalence of insomnia among U.S. and Canadian adults may be driven by the sharp reduction in the use of hormone replacement therapy following the 2002 report from the Women’s Health Initiative, Sheila N. Garland, PhD, said at the annual meeting of the Associated Professional Sleep Societies.

“In 2002 the Women’s Health Initiative came out with findings that hormone replacement therapy increased the risk of coronary heart disease, breast cancer, stroke, and pulmonary embolism [JAMA. 2002 Jul 17;288(3):321-33]. A lot of women on hormone replacement therapy up until 2002 stopped using it then. The increase in difficulty sleeping we found between 2002 and 2012 could perhaps represent an untreated menopausal symptom,” according to Dr. Garland, a psychologist at Memorial University of Newfoundland in St. John’s.

She presented an analysis of data from the Canadian Community Health Survey, a national once-per-decade survey, which included 34,118 adults aged 20-80 years and older in the 2002 version and 23,089 in 2012.

The key finding from the standpoint of sleep medicine, the prevalence of self-reported trouble sleeping, increased from 15.6% in 2002 to 17.1% in 2012. And this increase was concentrated in 40- to 59-year-old women, where the prevalence of insomnia or poor sleep rose from 19% to 24.3%, the highest of any age group. Rates remained flat over time in men and women aged 20-39 years and 60-80 years and older as well as in 40- to 59-year-old men.
