2013-08-02

Recent research and policy around sudden unexpected death in infancy (SUDI) have emphasised the place of safe sleeping practices within SUDI prevention strategies. Maori SUDI prevention workers have focussed on innovations around the safe sleep environment for some time now, as they have grappled with difficult to change and disproportionately high Maori SUDI rates. The wahakura (a flax bassinet modelled on a traditional Maori infant sleeping item) was developed in 2006 aiming to mitigate some of the risks of bedsharing with vulnerable infants, in particular infants exposed to maternal smoking in pregnancy. Early wahakura projects in Gisborne and Hawke's Bay showed high acceptability, effectiveness as an infant health promotion vehicle but difficulty maintaining a low/no cost supply for vulnerable families. The Hawke's Bay project revealed two pathways forward: the need for robust research to ensure the safety of the wahakura and the exploration of financially viable and more readily available alternatives. Work on both pathways is currently in progress around the country, signalling New Zealand's ongoing contribution to SUDI prevention and its potential contribution to knowledge and practices applicable to indigenous and other marginalised communities worldwide.

Consequences of the "back to sleep" program in infants.

PubMed

Miller, Lauren C; Johnson, Arlene; Duggan, Lisa; Behm, Melissa

2011-08-01

Sudden infant death syndrome (SIDS) is the third leading cause of infant mortality in the United States and the leading cause of death among infants 28-364 days of age. The "Back to Sleep" program was implemented in 1992 to promote supine sleeping in efforts to prevent SIDS. Along with this implementation came several consequences that are avoidable in infants. The purposes of this article are to describe the Back to Sleep program and its intended purpose, to identify the adverse consequences, and to develop a teaching program for nurse practitioners to use with parents that will both promote safe sleeping and reduce the untoward consequences of the back to sleep program while maintaining the integrity of the SIDS prevention advice.

Comparison of Text Messages Versus E-mail When Communicating and Querying With Mothers About Safe Infant Sleep.

PubMed

Moon, Rachel Y; Hauck, Fern R; Kellams, Ann L; Colson, Eve R; Geller, Nicole L; Heeren, Timothy C; Kerr, Stephen M; Corwin, Michael J

To assess how mothers' choice of e-mail or text messages (SMS) to receive safe sleep communications is associated with educational video viewing and responses to care practice queries. Seven hundred ninety-two new mothers received safe sleep-related communications for 60 days after newborn hospital discharge as part of a trial of health education interventions on infant care practices. Mothers chose e-mail or SMS for study communications and were sent 22 short safe sleep videos and 41 queries regarding infant care practices. Study communications via e-mail were elected by 55.7% of participants. The SMS group had a modestly higher overall view rate of videos (59.1% vs 54.4%; adjusted odds ratio [aOR], 1.39; 95% confidence interval [CI], 1.07-1.81) and a substantially higher response rate to queries (70.0% vs 45.2%; aOR, 3.48; 95% CI, 2.74-4.43). Participants more commonly opted to receive infant care practice videos and queries via e-mail. SMS was associated with higher viewing and response rates, especially for query responses. These results highlight the importance of understanding how specific modalities of communication might vary in reach. Copyright © 2017 Academic Pediatric Association. Published by Elsevier Inc.

2017-01-01

Qualitative interviews with mothers of babies at higher risk of sudden infant death syndrome (SIDS) were carried out to understand their views and decision-making process on the infant sleep environment and safe sleep messages. Twenty semi-structured interviews were conducted between February and November 2014 in deprived areas of Bristol, UK. Mothers were asked about their decision-making for the infant sleep environment and safe sleep messages including infant sleep position, co-sleeping, smoking, dummy use, feeding and disrupted routines. The interviews were transcribed, coded and thematic analysis carried out. Participants were invited based on an algorithm developed in a previous SIDS case control study that identified an increased risk of SIDS from four demographic characteristics: young maternal age, smoking during pregnancy, three or more children, and a measure of deprivation. The presence of three, or more characteristics led to being invited to take part in the qualitative study. Factors influencing mothers' adherence to the safe sleep messages included previous experience and the credibility of the advice given. They described disrupted routines that led to risky scenarios with a belief that occasional risks were acceptable. Where circumstances made following the advice more difficult they found alternative strategies to reduce the risk, including the use of movement monitors, regular checking and a belief that lighter maternal sleep in the presence of a baby was protective. Safer sleep messages should be tailored to fit with the lived realities of mothers, especially those at higher risk. The traditional list of 'do's' and 'don'ts' was not well accepted by this group. Interventions that seek to influence this higher-risk group should acknowledge mothers' own protective instincts and consider their beliefs and understanding behind the safer sleep messages if they are to be effective and encourage this group to change.

Speaking out on safe sleep: evidence-based infant sleep recommendations.

PubMed

Bartick, Melissa; Smith, Linda J

2014-11-01

The American Academy of Pediatrics (AAP) issued recommendations in 2005 and 2011 to reduce sleep-related infant death, which advise against all bedsharing for sleep. These recommendations overemphasize the risks of bedsharing, and this overemphasis has serious unintended consequences. It may result in increased deaths on sofas as tired parents try to avoid feeding their infants in bed. Current evidence shows that other risks are far more potent, such as smoking, shared sleep on sofas, sleeping next to impaired caregivers, and formula feeding. The emphasis on separate sleep is diverting resources away from addressing these critical risk factors. Recommendations to avoid bedsharing may also interfere with breastfeeding. We examine both the evidence behind the AAP recommendations and the evidence omitted from those recommendations. We conclude that the only evidence-based universal advice to date is that sofas are hazardous places for adults to sleep with infants; that exposure to smoke, both prenatal and postnatal, increases the risk of death; and that sleeping next to an impaired caregiver increases the risk of death. No sleep environment is completely safe. Public health efforts must address the reality that tired parents must feed their infants at night somewhere and that sofas are highly risky places for parents to fall asleep with their infants, especially if parents are smokers or under the influence of alcohol or drugs. All messaging must be crafted and reevaluated to avoid unintended negative consequences, including impact on breastfeeding rates, or falling asleep in more dangerous situations than parental beds. We must realign our resources to focus on the greater risk factors, and that may include greater investment in smoking cessation and doing away with aggressive formula marketing. This includes eliminating conflicts of interest between formula marketing companies and organizations dedicated to the health of children.

Safe sleep, day and night: mothers' experiences regarding infant sleep safety.

To explore Canadian mothers' experiences with infant sleep safety. Parents decide when, how and where to place their infants to sleep. It is anticipated that they will follow international Sudden Infant Death Syndrome prevention sleep safety guidelines. Limited evidence is available for how parents take up guidelines; no studies have explored Canadian mothers' experiences regarding infant sleep safety. An inductive qualitative descriptive study using some elements of grounded theory, including concurrent data collection and analysis and memoing. Semi-structured interviews and constant comparative analysis were employed to explore infant sleep safety experiences of 14 Canadian mothers residing in Metro Vancouver. Data collection commenced in December 2012 and ended in July 2013. The core theme, Infant Sleep Safety Cycle, represents a cyclical process encompassing sleep safety from the prenatal period to the first six months of infants' lives. The cyclical process includes five segments: mothers' expectations of sleep safety, their struggles with reality as opposed to maternal visions, modifications of expectations, provision of rationale for choices and shifts in mothers' views of infants' developmental capabilities. Mothers' experiences were influenced by four factors: perceptions of everyone's needs, familial influences, attitudes and judgments from outsiders and resource availability and accessibility. To manage infants' sleep, mothers reframed sleep safety guidelines and downplayed the risk of Sudden Infant Death Syndrome for all forms of sleep at all times. Healthcare providers can support mothers' efforts to manage their infants' sleep challenges. During prenatal and postpartum periods, providers' interventions can influence mothers' efforts to adhere to sleep safety principles. The study findings support healthcare providers' efforts to assist mothers to modify expectations and develop strategies to support sleep safety principles while acknowledging their challenges. © 2016 John Wiley & Sons Ltd.

Bedsharing at home, breastfeeding and sudden infant death.Recommendations for health professionals

PubMed

Jenik, Alejandro; Conti, Roxana

2017-10-01

The Sudden and Unexpected Infant Death Task Force together with the Subcommittee on Breastfeeding of the Sociedad Argentina de Pediatría have issued updated recommendations on bedsharing with the parents, a practice which remains controversial. Sleeping with the mother maximizes breastfeeding, which is protective against Sudden Infant Death. There is a small group of infants that have been associated with an increased risk of Sudden Infant Death and fatal sleeping accidents in certain circumstances. These hazards include parental smoking, sedating drugs or medication and alcohol consumption prior to sleep and sofa sharing situations. Bedsharing by breastfeeding mothers with their infants, in the absence of the above-mentioned risk factors, and with parents aware of how to ensure a safe infant sleep environment has not been shown to be associated with increased risk of Sudden Infant Death. This guidance does not advise on telling parents that they must never sleep with the baby, but rather instructs health professionals to give parents balanced advice to allow informed decision making, emphasizing the concept that parental room sharing without bedsharing is the safest place for the babies to sleep

Infant-parent bedsharing increases the risk of SIDS and other sleep-related deaths. Despite AAP recommendations to avoid bedsharing, public health efforts have been unsuccessful in changing behaviors. African-American infants are more than twice as likely to die from SIDS and other sleep-related deaths, and are also twice as likely to bedshare with their parents. Further, African-American parents have a high degree of self-efficacy with regards to preventing infant suffocation, but low self-efficacy with regards to SIDS risk reduction. It is unclear whether messages emphasizing suffocation prevention will decrease bedsharing. To evaluate the impact of specific health messages on African-American parental decisions regarding infant sleep location. We conducted a randomized, controlled trial of African-American mothers of infants. The control group received standard messaging emphasizing AAP-recommended safe sleep practices, including avoidance of bedsharing, for the purposes of SIDS risk reduction. The intervention group received enhanced messaging emphasizing safe sleep practices, including avoidance of bedsharing, for both SIDS risk reduction and suffocation prevention. Participants completed interviews at 2-3 weeks, 2-3 months, and 5-6 months after the infant's birth. 1194 mothers were enrolled in the study, and 637 completed all interviews. Bedsharing, both usually (aOR 1.005 [95 % CI 1.003, 1.006]) and last night (aOR 1.004 [95 % CI 1.002, 1.007]) increased slightly but statistically significantly with infant age (p < 0.001). Receipt of the enhanced message did not impact on sleep location. Maternal belief that bedsharing increased the risk of SIDS or suffocation declined over 6 months (p < 0.001) and did not differ by group assignment. African-American mothers who received an enhanced message about SIDS risk reduction and suffocation prevention were no less likely to bedshare with their infants.

Are baby hammocks safe for sleeping babies? A randomised controlled trial.

Chiu, Karen; Tonkin, Shirley L; Gunn, Alistair J; McIntosh, Christine C

2014-07-01

Two reports of infants found dead after sleeping in baby hammocks have raised international concern about the safety of infant hammocks. We therefore tested whether hammock sleep affected oxygenation in infants, when they were at an age of high risk of sudden, unexpected infant death. Healthy, full-term 4- to 8-week-old infants were randomised to sleep either in a commercially available hammock (n = 14) or a standard bassinet (n = 9), and sleep state, oxygen desaturation (a fall in peripheral haemoglobin oxygen saturation (SpO2 ) ≥ 4%, for ≥ 4 sec from baseline to nadir), apnoea and hypopnoea, and mean SpO2 were analysed. There was no significant difference in mean SpO2 (both 98.5%) or rate of oxygen desaturation events between the hammock and the bassinet cot (mean ± SD, 24 ± 20 vs. 28 ± 23 events per hour), but infants slept less in the hammock (59 ± 31 vs. 81 ± 34 min, p < 0.02). When correctly used, the hammock sleep position did not compromise the upper airway of sleeping infants. The significance of shorter duration of sleep in the hammocks is unclear. These findings should not be applied to all baby hammocks, nor to older babies, particularly once the infant can roll. Given that it is not possible to predict when an infant will be able to roll, we strongly recommend that hammocks should not be used for unsupervised sleep. ©2014 Foundation Acta Paediatrica.

To assess the association between maternal birth country and adherence to the American Academy of Pediatrics safe sleep recommendations in a national sample of Hispanic mothers, given that data assessing the heterogeneity of infant care practices among Hispanics are lacking. We used a stratified, 2-stage, clustered design to obtain a nationally representative sample of mothers from 32 US intrapartum hospitals. A total of 907 completed follow-up surveys (administered 2-6 months postpartum) were received from mothers who self-identified as Hispanic/Latina, forming our sample, which we divided into 4 subpopulations by birth country (US, Mexico, Central/South America, and Caribbean). Prevalence estimates and aORs were determined for infant sleep position, location, breastfeeding, and maternal smoking. When compared with US-born mothers, we found that mothers born in the Caribbean (aOR 4.56) and Central/South America (aOR 2.68) were significantly more likely to room share without bed sharing. Caribbean-born mothers were significantly less likely to place infants to sleep supine (aOR 0.41). Mothers born in Mexico (aOR 1.67) and Central/South America (aOR 2.57) were significantly more likely to exclusively breastfeed; Caribbean-born mothers (aOR 0.13) were significantly less likely to do so. Foreign-born mothers were significantly less likely to smoke before and during pregnancy. Among US Hispanics, adherence to American Academy of Pediatrics safe sleep recommendations varies widely by maternal birth country. These data illustrate the importance of examining behavioral heterogeneity among ethnic groups and have potential relevance for developing targeted interventions for safe infant sleep.

The goal of this qualitative study was to examine factors influencing decisions by black parents regarding use of soft bedding and sleep surfaces for their infants. We conducted focus groups and individual interviews with black mothers of lower and higher socioeconomic status (SES). Mothers were asked about many infant care practices, including sleep surface and bedding. Eighty-three mothers were interviewed, 73 (47 lower and 26 higher SES) in focus groups and 10 (7 lower and 3 higher SES) in individual interviews. The primary reason for using soft surfaces was infant comfort. Parents perceived that infants were uncomfortable if the surface was not soft. Many parents also interpreted "firm sleep surface" to mean taut; they were comfortable with and believed that they were following recommendations for a firm sleep surface when they placed pillows/blankets on the mattress as long as a sheet was pulled tautly over the pillows/blankets. The primary reasons for using soft bedding (including bumper pads) were comfort, safety, and aesthetics. In addition to using bedding to soften sleep surfaces, bedding was used to prevent infant rollover and falls, particularly for infants sleeping on a bed or sofa. Some parents used soft bedding to create an attractive space for the infant. Many black parents believe that soft bedding will keep their infant safe and comfortable. There is much misunderstanding about the meaning of a "firm" sleep surface. Additional educational messages apparently are needed to change parental perceptions and practices.

Use of potentially hazardous bedding, as defined by the American Academy of Pediatrics (eg, pillows, quilts, comforters, loose bedding), is a modifiable risk factor for sudden infant death syndrome and unintentional sleep-related suffocation. The proportion of US infants sleeping with these types of bedding is unknown. To investigate the US prevalence of and trends in bedding use, we analyzed 1993-2010 data from the National Infant Sleep Position study. Infants reported as being usually placed to sleep with blankets, quilts, pillows, and other similar materials under or covering them in the last 2 weeks were classified as bedding users. Logistic regression was used to describe characteristics associated with bedding use. From 1993 to 2010, bedding use declined but remained a widespread practice (moving average of 85.9% in 1993-1995 to 54.7% in 2008-2010). Prevalence was highest for infants of teen-aged mothers (83.5%) and lowest for infants born at term (55.6%). Bedding use was also frequently reported among infants sleeping in adult beds, on their sides, and on a shared surface. The rate of decline in bedding use was markedly less from 2001-2010 compared with 1993-2000. For 2007 to 2010, the strongest predictors (adjusted odds ratio: ≥1.5) of bedding use were young maternal age, non-white race and ethnicity, and not being college educated. Bedding use for infant sleep remains common despite recommendations against this practice. Understanding trends in bedding use is important for tailoring safe sleep interventions.

Implementation of the American Academy of Pediatrics recommendations to reduce sudden infant death syndrome risk in neonatal intensive care units: An evaluation of nursing knowledge and practice.

There is a direct relationship between nonsupine sleeping and sudden infant death syndrome (SIDS). Premature infants are at greater risk for SIDS and are often cared for in nonsupine positions during the course of hospitalization. Healthy premature infants should be placed supine for sleep before discharge from the neonatal intensive care unit (NICU), and parents receive specific instruction about infant sleep position and other risk factors for SIDS. Most published literature addressing nursing practices for SIDS reduction reflects practices with the healthy newborn population. To examine and describe NICU nurses' knowledge of SIDS risk-reduction measures, modeling of safe infant sleep interventions prior to discharge, and inclusion of SIDS risk reduction in parent education. Convenience sample of nurses practicing in level II and III NICUs located in 2 Middle Atlantic States. A prospective survey design was used for the study. The 14-item questionnaire was developed by a team of neonatal clinical experts and distributed via site coordinators to nurses in 19 NICUs. A total of 1080 surveys were distributed and 430 (40%) NICU nurses completed the survey. The majority of nurses (85%) identified the American Academy of Pediatrics SIDS risk-reduction strategies for safe sleep. The investigators found that age, years of nursing and neonatal nursing experience, and educational preparation did not significantly contribute to the practice of "supine-only" position for sleep for infants in NICUs. The study revealed that nurses frequently position healthy preterm infants supine for sleep when weaned to an open crib (50%). Others wait one to a few days before discharge (15%) and some never position supine for sleep (6%). Stuffed toys are removed from cribs 90.5% of the time. For term infants without major medical complications, 45.5% of surveyed nurses continued to use positioning aids/rolls in infants' cribs. The most common reasons nurses cited to position preterm infants side-lying or prone in a crib were fear of aspiration (29%), infant comfort (28%), and infant safety (20%). NICU nurses educated parents about SIDS and reduction strategies, using various media. At discharge, 73% of the nurses verbally communicated with parents, 53% provided printed literature, and 14% used audiovisual aids with parents. NICU nurses are in influential positions to educate parents and model SIDS risk-reduction strategies. This study supports other published research that points to inconsistencies in nursing practice regarding implementation of methods to reduce the risk of SIDS.

To evaluate the impact of specific health messages on the decisions of African American parents regarding soft bedding use, specifically related to the high degree of self-efficacy that African American parents have with regards to preventing infant suffocation vs low self-efficacy with regards to sudden infant death syndrome (SIDS) risk reduction. We conducted a randomized, controlled clinical trial of African American mothers of infants. The control group received standard messaging emphasizing safe sleep practices recommended by the American Academy of Pediatrics for the purposes of SIDS risk reduction. The intervention group received enhanced messaging emphasizing safe sleep practices for both SIDS risk reduction and suffocation prevention. Participants completed interviews at 2-3 weeks, 2-3 months, and 5-6 months after the infant's birth. Of 1194 mothers enrolled, 637 completed all interviews. The use of soft bedding both in the past week and last night declined with age (P < .001). Infants in the enhanced group had a lower rate of use of soft bedding in the past week (P = .006) and last night (P = .013). Mothers who received the enhanced message were more likely to state that they avoided soft bedding to protect their infant from suffocation. African American mothers who receive an enhanced message about SIDS risk reduction and suffocation prevention are less likely to use soft bedding in their infant's sleep environment.

Understanding the Risks Sitting and Carrying Devices Pose to Safe Infant Sleep.

PubMed

Rholdon, Roger

There have been various campaigns and recommendations to decrease the incidence of sudden unexpected infant death. Despite this, caregivers continue to place infants in unsafe sleeping environments. These environments, such as sitting devices, slings, carriers, and car seats, pose a significant risk to an infant's safety because of the risk from suffocation and cardiorespiratory instability. It is important for health care providers to understand the appropriate use of car seats, slings, and other sitting devices, to model appropriate behaviors, and to educate parents and caregivers. All parents, hospital staff, and other caregivers should understand the potential dangers associated with the inappropriate use of sitting devices for routine sleep. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

There is much misunderstanding about the meaning of a “firm” sleep surface. Additional educational messages apparently are needed to change parental perceptions and practices. PMID:21859921

Guidance recommends 'back to sleep' positioning for infants from birth in order to reduce the risk of sudden infant death. Exceptions have been made for babies with severe respiratory difficulties where lateral positioning may be recommended, although uncertainty exists for other conditions affecting the upper airway structures, such as cleft palate. This paper presents research of (i) current advice on sleep positioning provided to parents of infants with cleft palate in the UK; and (ii) decision making by clinical nurse specialists when advising parents of infants with cleft palate. A qualitative descriptive study used data from a national survey with clinical nurse specialists from 12 regional cleft centres in the UK to investigate current practice. Data were collected using semi-structured telephone interviews and analysed using content analysis. Over half the regional centres used lateral sleep positioning based on clinical judgement of the infants' respiratory effort and upper airway obstruction. Assessment relied upon clinical judgement augmented by a range of clinical indicators, such as measures of oxygen saturation, heart rate and respiration. Specialist practitioners face a clinical dilemma between adhering to standard 'back to sleep' guidance and responding to clinical assessment of respiratory effort for infants with cleft palate. In the absence of clear evidence, specialist centres rely on clinical judgement regarding respiratory problems to identify what they believe is the most appropriate sleeping position for infants with cleft palate. Further research is needed to determine the best sleep position for an infant with cleft palate. What is Known • Supine sleep positioning reduces the risk of sudden infant death in new born infants. • There is uncertainty about the benefits or risks of lateral sleep positioning for infants with upper airway restrictions arising from cleft palate. What is New • Variability exists in the information/advice provided to parents of infants with cleft palate regarding sleep positioning. • Over half the national specialist centres for cleft palate in the UK advise positioning infants with CP in the lateral position as a routine measure to reduce difficulties with respiration.

To assess the impact of "This Side Up" T-shirts on parental practices in Nebraska. A random sample of 3,210 Nebraska women who gave birth in 2004, stratified by race/ethnicity, was mailed a brief questionnaire on their receipt of a T-shirt and SIDS risk reduction materials at their birthing hospital, and on infant sleep position. Response rates were low (25.9%), ranging from 10.6% for Native American mothers to 46.4% for White mothers. Half (52.0%) had received a T-shirt and 71.6% had received SIDS information. Two-thirds (64.0%) reported that their infants slept on their backs; African-American and Hispanic infants were significantly less likely to back sleep. In univariate logistic regression models, African-American race, Hispanic ethnicity and maternal age 30-39 were significant negative predictors of back sleeping; White race and having received a SIDS brochure were positive predictors. In the fully controlled model African American and Asian race and Hispanic ethnicity were negative predictors of back sleeping; neither receiving SIDS information nor the infant T-shirt was significant. Effects of maternal age and a SIDS informational brochure appeared in models stratified by race/ethnicity. In these data, receiving an infant T-shirt was not related to how mothers placed their infants to sleep. Additional research is needed on effective methods of delivering targeted counseling and promoting safe sleep practices among families, particularly among racial and ethnic subgroups.

The 1994 Back to Sleep public education campaign resulted in dramatic reductions in sleep-related infant deaths, but comparable progress in recent years has been elusive. We conducted qualitative analyses of recent safe sleep campaigns from 13 U.S. cities. Goals were to (a) determine whether the campaigns reflect the full range of American Academy of Pediatrics (AAP) 2011 safe sleep recommendations, (b) describe tone and framing of the messages (e.g., use of fear appeals), (c) describe targeting/tailoring of messages to priority populations, and (d) ascertain whether the campaigns have been evaluated for reach and/or effectiveness. Methods included computer-assisted analyses of campaign materials and key informant interviews. All campaigns included "ABC" (Alone, Back, Crib) messaging; many ignored other AAP recommendations such as breastfeeding, room-sharing, immunizations, and avoiding smoke exposure. Campaigns frequently targeted priority populations such as African Americans. Fear appeals were used in three quarters of the campaigns, and 60% of the fear-based campaigns used guilt/blame messaging. We did not find published evaluation data for any of the campaigns. More attention is needed in public education campaigns to the full range of AAP recommendations, and evaluations are needed to determine the impact of these interventions on knowledge, behavior, and health outcomes.

Sudden and unexplained death is a leading cause of infant mortality. Certain characteristics of the sleep environment increase the risk for sleep-related sudden and unexplained infant death. These characteristics have the potential to generate asphyxial conditions. We tested the hypothesis that infants may be exposed to differing degrees of asphyxia in sleep environments, such that vulnerable infants with a severe underlying brainstem deficiency in serotonergic, γ-aminobutyric acid-ergic, or 14-3-3 transduction proteins succumb even without asphyxial triggers (e.g., supine), whereas infants with intermediate or borderline brainstem deficiencies require asphyxial stressors to precipitate death. We classified cases of sudden infant death into categories relative to a "potential asphyxia" schema in a cohort autopsied at the San Diego County Medical Examiner's Office. Controls were infants who died with known causes of death established at autopsy. Analysis of covariance tested for differences between groups. Medullary neurochemical abnormalities were present in both infants dying suddenly in circumstances consistent with asphyxia and infants dying suddenly without obvious asphyxia-generating circumstances. There were no differences in the mean neurochemical measures between these 2 groups, although mean measures were both significantly lower (P < .05) than those of controls dying of known causes. We found no direct relationship between the presence of potentially asphyxia conditions in the sleep environment and brainstem abnormalities in infants dying suddenly and unexpectedly. Brainstem abnormalities were associated with both asphyxia-generating and non-asphyxia generating conditions. Heeding safe sleep messages is essential for all infants, especially given our current inability to detect underlying vulnerabilities.

The annual report of the Regional Infant and Child Mortality Review Committee (RICMRC) is presented. This Committee has as its mission the review of infant and child deaths so that information can be transformed into action to protect young lives. The 2004 review area includes South Dakota's Minnehaha, Turner, Lincoln, Moody, Lake, McCook, Union, Hansen, and Miner counties. For the first time since the inception of RICMRC in 1997, there were no Sudden Infant Death Syndrome (SIDS) deaths in our region. Nevertheless, within our region we need to continue to promote the "Back to Sleep" campaign message of not only placing infants to sleep on their backs, but also making sure infants are put down to sleep on safe, firm, sleeping surfaces. There were ten deaths due to accidental injury. Four deaths were related to motor vehicle crashes (versus ten in 2003). Six children died in fires (versus three in 2003). There were no child abuse homicides and two teenage suicides. The RICMRC invites other communities to join in its efforts to review deaths to prevent potential life threatening hazards to children in their local environs.

To compare risk factors for infant sleep-related deaths under the supervision of parents and nonparents. We conducted a secondary analysis of sleep-related infant deaths from 2004 to 2014 in the National Center for Fatality Review and Prevention Child Death Review Case Reporting System. The main exposure was supervisor at time of death. Primary outcomes included sleep position, location, and objects in the environment. Risk factors for parental vs nonparental supervisor were compared using χ 2 and multivariable logistic regression models. Risk factors associated with different nonparental supervisors were analyzed using χ 2 . Of the 10 490 deaths, 1375 (13.1%) occurred under nonparental supervision. Infants who died under nonparental supervision had higher adjusted odds of dying outside the home (OR 12.87, 95% CI 11.31-14.65), being placed prone (OR 1.61, 95% CI 1.39-1.86) or on their side (OR 1.35, 95% CI 1.12-1.62), or being found prone (OR 1.74, 95% CI 1.50-2.02). Among infants who died under nonparental supervision, those supervised by relatives or friends were more often placed on an adult bed or couch for sleep and bed sharing (P < .0001), and to have objects in the sleep environment (P = .01). Infants who died of sleep-related causes under nonparental supervision were more likely to have been placed nonsupine. Among nonparental supervisors, relatives and friends were more likely to use unsafe sleep environments, such as locations other than a crib or bassinet and bed sharing. Pediatricians should educate parents that all caregivers must always follow safe sleep practices. Copyright © 2018 Elsevier Inc. All rights reserved.

Randomized Trial of a Children's Book Versus Brochures for Safe Sleep Knowledge and Adherence in a High-Risk Population.

Sleep-related infant deaths have plateaued in the past decade, disproportionately affecting low socioeconomic status (SES) families. Printed materials are widely used for anticipatory guidance, yet none for safe sleep has been studied. We tested the efficacy of a specially designed children's book compared to brochures for safe sleep knowledge and adherence, which we hypothesized would be greater due to superior readability and engagement. This randomized controlled trial involved low-SES mothers (n = 282) enrolled in a home visiting program. Home visitors (n = 56) were randomly assigned to perform safe sleep teaching and assessments during 3 visits: third trimester, 1 week old, and 2 months old, exclusively utilizing a specially designed children's book or brochures, and surveys incorporating the American Academy of Pediatrics' safe sleep recommendations. Outcomes were safe sleep knowledge, adherence, and usefulness of materials, controlling for maternal health literacy. Safe sleep knowledge increased across all time points with no overall group difference, though gains for sleep-evocative and general health items varied. Odds of bed sharing were higher and exclusive crib use lower for the brochure group (P < .05). Mothers and home visitors reported similar usefulness, though home visitors reported greater dialogue via the book and mothers in the book group reported more book sharing with their baby. While a specially designed children's book and brochures were equally effective conveying aggregate safe sleep knowledge in low-SES mothers, adherence to exclusive crib use and avoiding bed sharing were greater in the book group, attributable to enhanced dialogue, readability and emotional engagement. Children's books are a promising mode of anticipatory guidance, warranting further investigation. Copyright © 2017 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

Revisiting safe sleep recommendations for African-American infants: why current counseling is insufficient.

The American Academy of Pediatrics recommends that children be placed in the supine position on firm bedding and not bed share with parents or other children. Health professionals increasingly understand that many African-American parents do not follow these recommendations, but little research exists on provider reactions to this non-compliance. This study was intended to better understand how low-income, African-American mothers understand and act upon safe sleep recommendations for newborns and how providers counsel these mothers. We conducted focus groups with 60 African-American, low-income, first-time mothers and telephone interviews with 20 providers serving these populations to explore provider counseling and patient decision making. The large majority of mothers reported understanding, but not following, the safe-sleeping recommendations. Key reasons for non-compliance included perceived safety, convenience, quality of infant sleep and conflicting information from family members. Mothers often take measures intended to mitigate risk associated with noncompliance, instead increasing SIDS risk. Providers recognize that many mothers are non-compliant and attribute non-compliance largely to cultural and familial influence. However, few provider attempts are made to mitigate SIDS risks from non-compliant behaviors. We suggest that counseling strategies should be adapted to: (1) provide greater detailed rationale for SIDS prevention recommendations; and (2) incorporate or acknowledge familial and cultural preferences. Ignoring the reasons for sleep decisions by African-American parents may perpetuate ongoing racial/ethnic disparities in SIDS.

The 2008 annual report of the Regional Infant and Child Mortality Review Committee (RICMRC) is presented. This committee has as its mission the review of infant and child deaths so that information can be transformed into action to protect young lives. The 2008 review area includes South Dakota's Minnehaha, Turner, Lincoln, Moody, Lake, McCook, Union, Hansen, Miner and Brookings counties. Within our region in 2008, there were six infant deaths labeled as Sudden Unexpected Infant Deaths (SUID), of which two met the criteria for the Sudden Infant Death Syndrome (SIDS). The four non-SIDS SUID deaths all represented deaths where asphyxia from unsafe sleeping environments could not be excluded. In addition, there were two accidental deaths from asphyxia in unsafe sleeping enviroments. We need to continue to promote the "Back to Sleep" campaign message of not only placing infants to sleep on their backs, but also making sure infants are put down to sleep on safe, firm, sleeping surfaces and are appropriately dressed for the ambient temperature. Parents need to be aware of the potential hazards of bed-sharing with their infants. In both 2007 and 2008, four children died in motor vehicle crashes, none of which were alcohol-related. Three fire-related childhood deaths were associated with one house fire involving a nonfunctional smoke alarm and a sleeping arrangement without an easy egress from a fire. Since 1997, the RICMRC has sought to achieve its mission to "review infant and child deaths so that information can be transformed into action to protect young lives". For 2008, the committee reviewed 21 deaths from Minnehaha, Turner, Lincoln, Moody, Lake, McCook, Union, Hansen, Miner and Brookings counties that met the following criteria: Children under the age of 18 dying subsequent to hospital discharge following delivery. Children who either died in these counties from causes sustained in them, or residents who died elsewhere from causes sustained in the ten-county region.

To review autopsy reports of all SUDI deaths in the Auckland region, New Zealand, from October 2000 to December 2009. Information on all SUDI cases from 2000 to 2009 was extracted from autopsy and police reports from the National Forensic Pathology Service at Auckland Hospital. Of the 332 post-mortems in this period, 221 were classified as SUDI. Of these, 83% were Māori or Pacific infants. The median age at death was 11 weeks and 11% occurred in 7- to 28-day-olds. At the time of death, 64% overall were bedsharing; this was more common in 7-28 day olds (92%). Bedsharing infants were significantly younger at death than non-bedsharing infants (p=0.008). Where sleep position was known, 57% were placed in non-supine at the last sleep. There was no evidence of diagnostic shift and the prevalence of bedsharing did not change over the decade. Bedsharing was associated with a high proportion of SUDI cases, especially in the youngest infants, and non-supine sleep positions were common. There is a need to enhance SUDI prevention messages and consider innovative ways of promoting safe sleeping environment and supine sleep position in Māori and Pacific communities. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

Safe Sleep Infant Care Practices Reported by Mothers of Twins.

PubMed

Damato, Elizabeth G; Haas, Madeline C; Czeck, Pamela; Dowling, Donna A; Barsman, Sarah Gutin

2016-12-01

The high prevalence of prematurity and low birth-weight places twin infants at increased risk for sudden unexpected infant death (SUID) and/or sudden infant death syndrome (SIDS). Risk for these SUID and SIDS is affected by a combination of nonmodifiable intrinsic risk factors and modifiable extrinsic stressors including infant care practices related to sleep. Although adherence to the full scope of American Academy of Pediatrics (AAP) 2011 recommendations is intended to decrease risk, these recommendations are aimed at singleton infants and may require tailoring for families with multiple infants. The study describes infant care practices reported by mothers of twins in the first 6 months postpartum. Mothers caring for twin infants (N = 35) were surveyed online both longitudinally (at 2, 8, 16, and 24 weeks after infant hospital discharge) and cross-sectionally. AAP recommendations (2011) guided survey content. The degree of adherence to AAP recommendations varied over time. For example, mothers of twins reported 100% adherence to placing twins supine for sleep initially, but many reported putting babies on their stomachs for naps as twins became older. Sharing a parent's bedroom decreased over time as did frequency of crib sharing. Fewer than half of mothers offered a pacifier most or all of the time for sleep. Opportunities exist for development of an educational program geared specifically for postpartum parents of twins. Barriers affecting adherence to AAP recommendations and effectiveness of educational programs addressing needs of this unique population need further exploration.

Credibility gap? Parents' beliefs about reducing the risk of cot death.

PubMed

Epstein, Joyce; Jolly, Clare

2009-11-01

This paper reports on findings from a survey of awareness and credibility of risk factors for sudden infant death and adherence to infant care advice, conducted with 506 mothers of children aged from six months to three years in England in 2007. The survey confirmed that many parents failed to follow recommended infant care practices to reduce the risk of cot death, such as supine sleeping and sleeping the baby in a cot in the same room as them. Notably, substantial proportions of mothers did not believe the evidence-based safe infant care messages that they have heard--about a fifth were not persuaded that exposing a baby to tobacco smoke increases the risk of cot death, over a quarter were not persuaded that prone sleeping is risky, and almost half were not persuaded that side sleeping is risky. The findings are discussed in the context of wider cultural issues bearing on the credibility of health advice. Practical suggestions for health visitors and other community practitioners include innovative ways to involve young, at-risk parents and credible influences upon them such as grandparents, alongside the use and promotion of new free resources from the Foundation for the Study of Infant Deaths.

An 8 year study of risk factors for SIDS: bed‐sharing versus non‐bed‐sharing

McGarvey, C; McDonnell, M; Hamilton, K; O'Regan, M; Matthews, T

2006-01-01

Background It is unclear if it is safe for babies to bed share with adults. In Ireland 49% of sudden infant death syndrome (SIDS) cases occur when the infant is bed‐sharing with an adult. Objective To evaluate the effect of bed‐sharing during the last sleep period on risk factors for SIDS in Irish infants. Design An 8 year (1994–2001) population based case control study of 287 SIDS cases and 831 controls matched for date, place of birth, and sleep period. Odds ratios and 95% confidence intervals were calculated by conditional logistic regression. Results The risk associated with bed‐sharing was three times greater for infants with low birth weight for gestation (UOR 16.28 v 4.90) and increased fourfold if the combined tog value of clothing and bedding was ⩾10 (UOR 9.68 v 2.34). The unadjusted odds ratio for bed‐sharing was 13.87 (95% CI 9.58 to 20.09) for infants whose mothers smoked and 2.09 (95% CI 0.98 to 4.39) for non‐smokers. Age of death for bed‐sharing and sofa‐sharing infants (12.8 and 8.3 weeks, respectively) was less than for infants not sharing a sleep surface (21.0 weeks, p<0.001) and fewer bed‐sharing cases were found prone (5% v 32%; p = 0.001). Conclusion Risk factors for SIDS vary according to the infant's sleeping environment. The increased risk associated with maternal smoking, high tog value of clothing and bedding, and low z scores of weight for gestation at birth is augmented further by bed‐sharing. These factors should be taken into account when considering sleeping arrangements for young infants. PMID:16243855

2017-01-01

Although several states have implemented programs providing boxes for infant sleep, safe sleep experts express concern regarding the paucity of safety and efficacy research on boxes. The purpose of this study was to assess pregnant women’s perceptions regarding use of baby sleep boxes. A convenience sample was recruited from a community prenatal education program. Twenty-eight women were administered a brief semistructured interview about their knowledge of baby sleep boxes, opinions about the boxes, and questions they would have. For most (n = 15, 54%), this was their first pregnancy. Participants self-identified as white (43%), black (36%), Hispanic (18%), and “other” (4%). Ten subthemes emerged related to previous knowledge of boxes (useful for families in need, historic precedent in other countries), positive attributes (portable, compact, affordable, decorative), and negative attributes (low to ground, structural integrity/design, stability, stigma). Research on safety and efficacy could reduce concerns, but issues of stigma may persist. PMID:29226192

The aim of this study was to identify the potential risks and benefits of sleeping infants in a Pēpi-Pod distributed to families with high risk of sudden unexpected death in infancy compared to a bassinet. Forty-five mostly indigenous Māori mothers who were referred by local health providers to receive a Pēpi-Pod were surveyed at recruitment, 1 and 3 months. A sleep study at 1 month included infrared video, oximetry and temperature measures. When compared with 89 historical bassinet controls, an intention-to-treat analysis of questionnaires showed no increase in direct bed sharing but demonstrated significantly less sharing of the maternal bedroom at both interviews, with the majority of those not sleeping in the maternal bedroom, actually sleeping in the living room. The 1 month 'as-used' analysis showed poorer maternal sleep quality. The 'as-used' analysis of video data (24 Pēpi-Pod and 113 bassinet infants) also showed no increase in direct bed sharing, head covering or prone/side sleep position. Differences in oxygen saturation were not significant, but heart rate was higher in the Pēpi-Pod infants by 8.37 bpm (95% confidence interval 4.40, 12.14). Time in the thermal comfort zone was not different between groups despite Pēpi-Pod infants being situated in significantly warmer rooms. Overall, we found that most differences in infant risk behaviours in a Pēpi-Pod compared to a bassinet were small, with confidence intervals excluding meaningful differences. We noted poorer maternal sleep quality at 1 month. Higher infant heart rates in the Pēpi-Pod group may be related to higher room temperatures. The Pēpi-Pod appears physiologically safe but is associated with lower reported maternal sleep quality. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Interventions to prevent sudden unexpected death in infancy (SUDI) have generally been population wide interventions instituted after case-control studies identified specific childcare practices associated with sudden death. While successful overall, in New Zealand (NZ), the rates are still relatively high by international comparison. This study aims to describe childcare practices related to SUDI prevention messages in a New Zealand community, and to develop and explore the utility of a risk assessment instrument based on international guidelines and evidence. Prospective longitudinal study of 209 infants recruited antenatally. Participant characteristics and infant care data were collected by questionnaire at: baseline (third trimester), and monthly from infant age 3 weeks through 23 weeks. Published meta-analyses data were used to estimate individual risk ratios for 6 important SUDI risk factors which, when combined, yielded a "SUDI risk score". Most infants were at low risk for SUDI with 72% at the lowest or slightly elevated risk (combined risk ratio ≤1.5). There was a high prevalence of the safe practices: supine sleeping (86-89% over 3-19 weeks), mother not smoking (90-92% over 3-19 weeks), and not bed sharing at a young age (87% at 3 weeks). Five independent predictors of a high SUDI risk score were: higher parity (P =0.028), younger age (P =0.030), not working or caring for other children antenatally (P =0.031), higher depression scores antenatally (P =0.036), and lower education (P =0.042). Groups within the community identified as priorities for education about safe sleep practices beyond standard care are mothers who are young, have high parity, low educational levels, and have symptoms of depression antenatally. These findings emphasize the importance of addressing maternal depression as a modifiable risk factor in pregnancy.

In this paper, a remote-controlled and microcontroller-based cradle is designed and constructed. This system is also called Remote Control of Microcontroller-Based Infant Stimulation System or the RECOMBIS System. Cradle is an infant stimulating system that provides relaxation and sleeping for the baby. RECOMBIS system is designed for healthy full-term newborns to provide safe infant care and provide relaxation and sleeping for the baby. A microcontroller-based electronic circuit was designed and implemented for RECOMBIS system. Electromagnets were controlled by 8-bit PIC16F84 microcontroller, which is programmed using MPASM package. The system works by entering preset values from the keyboard, or pulse code modulated radio frequency remote control system. The control of the system and the motion range were tested. The test results showed that the system provided a good performance.

The northern territory Nunavut has Canada's largest jurisdictional land mass with 33,322 inhabitants, of which 85% self-identify as Inuit. Nunavut has rates of infant mortality, postneonatal mortality and hospitalisation of infants for respiratory infections that greatly exceed those for the rest of Canada. The infant mortality rate in Nunavut is 3 times the national average, and twice that of the neighbouring territory, the Northwest Territories. Nunavut has the largest Inuit population in Canada, a population which has been identified as having high rates of Sudden Infant Death Syndrome (SIDS) and infant deaths due to infections. To determine the causes and potential risk factors of infant mortality in Nunavut, we reviewed all infant deaths (<1 yr) documented by the Nunavut Chief Coroner's Office and the Nunavut Bureau of Statistics (n=117; 1999-2011). Rates were compared to published data for Canada. Sudden death in infancy (SIDS/SUDI; 48%) and infection (21%) were the leading causes of infant death, with rates significantly higher than for Canada (2003-2007). Of SIDS/SUDI cases with information on sleep position (n=42) and bed-sharing (n=47), 29 (69%) were sleeping non-supine and 33 (70%) were bed-sharing. Of those bed-sharing, 23 (70%) had two or more additional risk factors present, usually non-supine sleep position. CPT1A P479L homozygosity, which has been previously associated with infant mortality in Alaska Native and British Columbia First Nations populations, was associated with unexpected infant death (SIDS/SUDI, infection) throughout Nunavut (OR:3.43, 95% CI:1.30-11.47). Unexpected infant deaths comprise the majority of infant deaths in Nunavut. Although the CPT1A P479L variant was associated with unexpected infant death in Nunavut as a whole, the association was less apparent when population stratification was considered. Strategies to promote safe sleep practices and further understand other potential risk factors for infant mortality (P479L variant, respiratory illness) are underway with local partners.

The aims of this longitudinal study were to examine (a) development of infant sleep and maternal sleep from 3 to 6 months postpartum; (b) concomitant and prospective links between maternal sleep and infant sleep; and (c) triadic links between paternal involvement in infant caregiving and maternal and infant sleep. The study included 57 families that were recruited during pregnancy. Maternal and infant sleep was assessed using actigraphy and sleep diaries for 5 nights. Both fathers and mothers completed a questionnaire assessing the involvement of fathers relative to mothers in infant caregiving. The results demonstrated moderate improvement in infant and maternal sleep percent between 3 and 6 months. Maternal sleep percent at 3 months significantly predicted infant sleep percent at 6 months. Greater paternal involvement in infant daytime and nighttime caregiving at 3 months significantly predicted more consolidated maternal and infant sleep at 6 months. These findings suggest that maternal sleep is an important predictor of infant sleep and that increased involvement of fathers in infant caregiving responsibilities may contribute to improvements in both maternal and infant sleep during the first 6 months postpartum. © 2015 The Society for Research in Child Development, Inc.

Public Health initiatives, such as the "Safe to Sleep" campaign, have traditionally targeted infants' risk factors for the prevention of Sudden Infant Death Syndrome (SIDS). However, controversy remains regarding maternal and obstetrical risk factors for SIDS. In our study, we sought out to determine both modifiable and non-modifiable obstetrical and maternal risk factors associated with SIDS. We conducted a population-based cohort study using the CDC's Linked Birth-Infant Death data from the United States for the year 2010. The impact of several obstetrical and maternal risk factors on the risk of overall infant mortality and SIDS was estimated using unconditional regression analysis, adjusting for relevant confounders. Our cohort consisted of 4,007,105 deliveries and 24,174 infant deaths during the first year of life, of which 1991 (8.2%) were due to SIDS. Prominent risk factors for SIDS included (OR [95% CI]): black race, 1.89 [1.68-2.13]; maternal smoking, 3.56 [3.18-3.99]; maternal chronic hypertension, 1.73 [1.21-2.48]; gestational hypertension, 1.51 [1.23-1.87]; premature birth <37 weeks, 2.16 [1.82-2.55]; IUGR, 2.46 [2.14-2.82]; and being a twin, 1.81 [1.43-2.29], p < 0.0001. Relative to a cohort of infants who died of other causes, risk factors with a predilection for SIDS were maternal smoking, 2.48 [2.16-2.83] and being a twin, 1.52 [1.21-1.91], p < 0.0001. Conclusions for practice: While certain socio-demographic and gestational characteristics are important risk factors, maternal smoking remains the strongest prenatal modifiable risk factor for SIDS. We recommend the continuation of Public Health initiatives that promote safe infant sleeping practices and smoking cessation during and after pregnancy.

This paper reports on findings of a survey of women's magazines and the internet looking at the extent to which images of babies reinforce or undermine safe infant care advice to reduce the risk of cot death. All images of babies printed in all issues of nine magazines over an eight-month period during 2009 to 2010 were reviewed. The review also included the first 20 pages of a Google search of UK sleeping babies conducted on one day in 2011. In total, 559 images were reviewed. A substantial proportion of images depicted unsafe situations, in particular side and prone sleeping and sleeping indoors with the head covered by a hat or other covering. There was a dearth of images of babies sleeping in the feet-to-foot position or with a dummy, both of which are included in FSID/Department of Health guidelines on reducing the risk of cot death. The findings are discussed in the context of health visitors' and other community practitioners' work and current government cuts in resources, and suggestions are made to respond to the situation.

Our goal was to examine associations of infant sleep and feeding patterns with maternal sleep and mood among women at risk for postpartum depression. Participants were 30 women (age ± SD = 28.3 ± 5.1 years) with a history of MDD (but not in a mood episode at enrollment) who completed daily sleep diaries, wore wrist actigraphs to estimate sleep, and had their mood assessed with the Hamilton Depression Rating Scale (HAM-D-17) during four separate weeks of the perinatal period (33 weeks pregnancy and weeks 2, 6, and 16 postpartum). They logged their infants' sleep and feeding behaviors daily and reported postnatal stress on the Childcare Stress Inventory (CSI) at week 16. Mothers' actigraphically estimated sleep showed associations with infant sleep and feeding patterns only at postpartum week 2. Shorter duration of the longest infant-sleep bout was associated with shorter maternal sleep duration (p = .02) and lower sleep efficiency (p = .04), and maternal sleep efficiency was negatively associated with the number of infant-sleep bouts (p = .008) and duration of infant feeding (p = .008). Neither infant sleep nor feeding was associated with maternal sleep at 6 or 16 weeks, but more disturbed infant sleep and more frequent feeding at 6 weeks were associated with higher HAM-D scores at 6 and 16 weeks and higher CSI scores. Sleep in the mother-infant dyad is most tightly linked in the early postpartum weeks, but mothers continue to experience disturbed sleep and infant sleep and feeding behaviors continue to be associated with mothers' depressive symptoms and stress ratings as long as 16 weeks postpartum. These data imply that interventions designed to improve maternal sleep and postpartum mood should include both mothers and infants because improving infant sleep alone is not likely to improve maternal sleep, and poor infant sleep is linked to postpartum depression and stress.

Purpose Our goal was to examine associations of infant sleep and feeding patterns with maternal sleep and mood among women at risk for postpartum depression. Methods Participants were 30 women (age±SD = 28.3±5.1 years) with a history of MDD (but not in a mood episode at enrollment) who completed daily sleep diaries, wore wrist actigraphs to estimate sleep, and had mood assessed with the Hamilton Depression Rating Scale (HAM-D-17) during 4 separate weeks of the perinatal period (33 weeks pregnancy and weeks 2, 6, and 16 postpartum). They logged their infants’ sleep and feeding behaviors daily and reported postnatal stress on the Childcare Stress Inventory (CSI) at week 16. Results Mothers’ actigraphically-estimated sleep showed associations with infant sleep and feeding patterns only at postpartum week 2. Shorter duration of the longest infant sleep bout was associated with shorter maternal sleep duration (p=.02) and lower sleep efficiency (p=.04), and maternal sleep efficiency was negatively associated with number of infant sleep bouts (p =.008) and duration of infant feeding (p =.008). Neither infant sleep nor feeding was associated with maternal sleep at 6 or 16 weeks, but more disturbed infant sleep and more frequent feeding at 6 weeks were associated with higher HAM-D scores at 6 and 16 weeks and higher CSI scores.

Findings from prior research into the effect of feeding methods on infant sleep are inconsistent. The objectives of this study were to examine infants' sleep patterns by feeding methods and sleep arrangement from birth to eight months old. This longitudinal cohort study enrolled 524 pregnant women at 34-41 weeks of gestation and their infants after delivery in 2006 and followed up until eight months postpartum. The study subjects were recruited from nine women and children hospitals in nine cities in China (Beijing, Chongqing, Wuhan, Changsha, Nanning, Xiamen, Xi'an, Jinan, and Hailin). Participating infants were followed up weekly during the first month and monthly from the second to the eighth month after birth. Twenty-four hour sleep diaries recording infants' sleeping and feeding methods were administered based on caregiver's self-report. Multivariable mixed growth curve models were fitted to estimate the effects of feeding methods and sleep arrangement on infants' sleep patterns over time, controlling for maternal and paternal age, maternal and paternal education level, household income, supplementation of complementary food, and infant birth weight and length. Exclusively formula fed infants had the greatest sleep percentage/24 h, followed by exclusively breast milk fed infants and partially breast milk fed infants (P<0.01). Night waking followed a similar pattern. However, the differences in sleep percentage and night waking frequency between exclusively formula and exclusively breast milk fed infants weakened over time as infants developed. In addition, compared to infants with bed-sharing sleep arrangement, those with room sharing sleep arrangement had greater daytime and 24-hour infant sleep percentage, whereas those with sleeping alone sleep arrangement had greater nighttime sleep percentage. Our data based on caregiver's self-report suggested that partial breastfeeding and bed-sharing may be associated with less sleep in infants. Health care professionals need to work with parents of newborns to develop coping strategies that will help prevent early weaning of breastfeeding.

Maternal and paternal depression has been associated with infants' behavioral sleep problems. Behavioral sleep interventions, which alter parental cognitions about infant sleep, have improved infant sleep problems. This study reports relationships between parental depression, fatigue, sleep quality, and cognitions about infant sleep pre and post-intervention for a behavioral sleep problem. This secondary analysis of data from Canadian parents (n = 455), with healthy infants aged 6-to-8-months exposed to a behavioral sleep intervention, examined baseline data and follow-up data from 18 or 24 weeks post intervention (group teaching or printed material) exposure. Parents reported on sleep quality, fatigue, depression, and cognitions about infant sleep. Data were analyzed using Pearson's r and stepwise regression analysis. Parents' fatigue, sleep quality, sleep cognitions, and depression scores were correlated at baseline and follow-up. At baseline, sleep quality (b = .52, 95% CI .19-.85), fatigue (b = .48, 95% CI .33-.63), doubt about managing infant sleep (b = .44, 95% CI .19-.69), and anger about infant sleep (b = .69, 95% CI .44-.94) were associated with mothers' depression. At baseline, fathers' depression related to sleep quality (b = .42, 95% CI .01-.83), fatigue (b = .47, 95% CI .32-.63), and doubt about managing infant sleep (b = .50, 95% CI .24-.76). At follow-up, mothers' depression was associated with sleep quality (b = .76, 95% CI .41-1.12), fatigue (b = .25, 95% CI .14-.37), doubt about managing infant sleep (b = .44, 95% CI .16-.73), sleep anger (b = .31, 95% CI .02-.59), and setting sleep limits (b = -.22, 95% CI -.41-[-.03]). At follow-up, fathers' depression related to sleep quality (b = .84, 95% CI .46-1.22), fatigue (b = .31, 95% CI .17-.45), sleep doubt (b = .34, 95% CI .05-.62), and setting sleep limits (b = .25, 95% CI .01-.49). Mothers' and fathers' cognitions about infant sleep demonstrate complex relationships with their depression scores. While mothers' setting sleep limit scores are associated with decreased depression scores, fathers' setting limits scores are associated with increased depression scores. Parental doubts about managing infant sleep and difficulties with setting sleep limits require attention in interventions.

Emotional availability at bedtime, infant temperament, and infant sleep development from 1 to 6 months

Infant sleep consolidates rapidly during the first half year of life in the context of a dynamic, bidirectional exchange between infant characteristics and the caregiving environment. The current study examined relations among mothers’ emotional availability (EA) at bedtime, infant temperament, and objectively assessed infant sleep development from 1 to 6 months, and in particular focused on whether infant temperament moderated linkages between EA at bedtime and infant sleep development. The sample consisted of seventy-two mother-infant dyads, and measures included actigraphy-assessed infant sleep at 1 and 6 months, observed maternal EA coded from bedtime videos at 3 and 6 months, and maternal reports of infant temperament at 3 and 6 months. Analysis showed significant positive effects of maternal EA at bedtime on developmental changes in infant sleep minutes. Additionally, infant temperamental surgency moderated the influence of EA at bedtime on the increase in infant sleep minutes. In other words, highly surgent infants increased their sleep time more than other infants if their mothers were emotionally available at bedtime. Results were discussed in terms of the transactional model of infant sleep development. PMID:27692276

Sleep arrangements, parent-infant sleep during the first year, and family functioning

The present longitudinal study addressed the ongoing debate regarding the benefits and risks of infant-parent co-sleeping by examining associations between sleep arrangement patterns across the first year of life and infant and parent sleep, marital and family functioning, and quality of mothers’ behavior with infants at bedtime. Patterns of infant sleep arrangements across the infants’ first year were derived from information obtained from 139 families at 1, 3, 6, 9, and 12 months of infant age in a U.S., central Pennsylvanian sample. Linkages between these patterns and parent-infant sleep, marital and coparenting stress, and maternal behavior at bedtime (from video-recordings) were assessed. Compared to families whose infants were solitary sleepers by 6 months, persistent co-sleeping was associated with sleep disruption in mothers but not in infants, although mothers in persistent co-sleeping arrangements reported that their infants had more frequent night awakenings. Persistent co-sleeping was also associated with mother reports of marital and coparenting distress, and lower maternal emotional availability with infants at bedtime (from home observations). Persistent co-sleeping appeared to be a marker of, though not necessarily a cause of, heightened family stress, although the present design did not enable strong tests of causal processes, and results may be particular to cultures that are not supportive of co-sleeping. Findings are discussed in terms of cultural contexts of infant sleep and the need for further investigations into the role of the health of the family system in influencing how parents structure infant sleep.

Household chaos and family sleep during infants' first year.

Whitesell, Corey J; Crosby, Brian; Anders, Thomas F; Teti, Douglas M

Household chaos has been linked with dysregulated family and individual processes. The present study investigated linkages between household chaos and infant and parent sleep, a self-regulated process impacted by individual, social, and environmental factors. Studies of relations between household chaos and child sleep have focused on older children and teenagers, with little attention given to infants or parent sleep. This study examines these relationships using objective measures of household chaos and sleep while controlling for, respectively, maternal emotional availability at bedtime and martial adjustment, in infant and parent sleep. Multilevel modeling examined mean and variability of sleep duration and fragmentation for infants, mothers, and fathers when infants were 1, 3, 6, 9, and 12 months (N = 167). Results indicated infants in higher chaos homes experienced delays in sleep consolidation patterns, with longer and more variable sleep duration, and greater fragmentation. Parent sleep was also associated with household chaos such that in higher chaos homes, mothers and fathers experienced greater variability in sleep duration, which paralleled infant findings. In lower chaos homes, parents' sleep fragmentation mirrored infants' decreasingly fragmented sleep across the first year and remained lower at all timepoints compared to parents and infants in high chaos homes. Collectively, these findings indicate that after controlling for maternal emotional availability and marital adjustment (respectively) household chaos has a dysregulatory impact on infant and parent sleep. Results are discussed in terms of the potential for chaos-induced poor sleep to dysregulate daytime functioning and, in turn, place parent-infant relationships at risk.

The 2007 annual report of the Regional Infant and Child Mortality Review Committee.

PubMed

Randall, Brad; Wilson, Ann L

2008-08-01

The mission of the Regional Infant and Child Mortality Review Committee (RICMRC) is to review infant and child deaths so that information can be transformed into action to protect young lives. The 2007 review area includes South Dakota's Minnehaha, Turner, Lincoln, Moody, Lake, McCook, Union, Hansen, Miner and Brookings counties. Although there were no deaths in 2007 that met the criteria of the Sudden Infant Death Syndrome (SIDS) in our region, there were three infant deaths associated with unsafe sleeping environments (including adult co-sleeping) that either caused or potentially may have caused these infants' deaths. We need to continue to promote the "Back to Sleep" campaign message of not only placing infants to sleep on their backs, but also making sure infants are put down to sleep on safe, firm sleeping surfaces and that they are appropriately dressed for the ambient temperature. Parents need to be aware of the potential hazards of co-sleeping with their infants. Compared to nine such deaths in 2006, only four deaths in 2007 involved motor-vehicle crashes, none of which were alcohol related. Two drowning deaths illustrated the rapidity in which even momentary caregiver distractions can lead to deaths in children in and around water. Since 1997 the Regional Infant and Child Mortality Review Committee (RICMRC) has sought to achieve its mission to "review infant and child deaths so that information can be transformed into action to protect young lives." For 2007, the committee reviewed 25 deaths from Minnehaha, Turner, Lincoln, Moody, Lake, McCook, Union, Hansen, Miner and Brookings counties that met the following criteria: Children under the age of 18 dying subsequent to hospital discharge following delivery. Children who either died in these counties from causes sustained in them, or residents who died elsewhere from causes sustained in the 10-county region. The report that follows reviews the committee's activities for 2007. No deaths meeting the criteria for Sudden Infant Death Syndrome (SIDS) occurred in the review region. The committee has observed a stable decline in the number of deaths due to the SIDS as compared to the eight SIDS or possible SIDS deaths occurring in 1999. Unfortunately, however, there were three infant deaths in SIDS-like settings where asphyxia could not be excluded. Although the committee strives to be consistent year to year in its investigation protocols, we have noticed that the number of deaths classified as "undetermined" has been increasing over the last few years (starting in 1997: 1, 2, 1, 0, 2, 1, 2, 0, 5, 4, 5). Although it is possible that deaths certified as SIDS in earlier years may now be classified as undetermined due to asphyxial risks, we may also be seeing an increase in infants sleeping in unsafe environments. Our data may be mirroring a national trend amongst death investigators to increasingly recognize asphyxial risks in infant death scenes. Infants co-sleeping with adults (two deaths in 2007) may represent a risk factor not as frequently seen as in prior years. We will watch this trend closely in the future. The Committee strenuously advocates that the Back to Sleep message include placing infants on their back to sleep, avoiding soft bedding for infants, making parents aware of the potential hazards of co-sleeping with young infants, and eliminating both pre- and post-delivery fetal/infant cigarette smoke exposure. a decrease in youth motor-vehicle crash deaths to four versus the nine seen in 2006.2 Three of those dying in motor-vehicle crashes in 2007 were not wearing seat belts. The committee continues to feel that some of these deaths could have been prevented had these children been wearing a seat belt. Compared to four alcohol-related motor-vehicle crash fatalities in 2006, no deaths in 2007 were alcohol related. The committee, however, is painfully aware that even one crash involving multiple occupants can rapidly skew the apparent improvements in 2007 in the wrong direction. In 2007, two youths, both with disabilities, drown. One drown in a bath tub and the other in an outdoor pool. It is unfortunate that these deaths bring home the message that even the smallest, momentary lapses in supervision of these children can have fatal consequences. Fortunately, the child and infant homicide rate in our region is very low. Unfortunately, however, one infant did die as a result of being assaulted and shaken by one of its parents. There remains a need for the community at large, and the medical community specifically, to address issues of parental anger management, particularly when caregiver frustration is directed at children.

Differences in infant and parent behaviors during routine bed sharing compared with cot sleeping in the home setting.

To observe the behavior of infants sleeping in the natural physical environment of home, comparing the 2 different sleep practices of bed sharing and cot sleeping quantifying to factors that have been identified as potential risks or benefits. Forty routine bed-sharing infants, aged 5-27 weeks were matched for age and season of study with 40 routine cot-sleeping infants. Overnight video and physiologic data of bed-share infants and cot-sleep infants were recorded in the infants' own homes. Sleep time, sleep position, movements, feeding, blanket height, parental checks, and time out of the bed or cot were logged. The total sleep time was similar in both groups (bed-sharing median: 8.6 hours; cot-sleeping median: 8.2 hours). Bed-sharing infants spent most time in the side position (median: 5.7 hours, 66% of sleep time) and most commonly woke at the end of sleep in this position, whereas cot-sleeping infants most commonly slept supine (median: 7.5 hours, 100%) and woke at the end of sleep in the supine position. Prone sleep was uncommon in both groups. Head covering above the eyes occurred in 22 bed-sharing infants and 1 cot-sleeping infant. Five of these bed-sharing infants were head covered at final waking time, but the cot-sleeping infant was not. Bed-sharing parents looked at or touched their infant more often (median: 11 vs 4 times per night) but did not always fully wake to do so. Movement episodes were shorter in the bed-sharing group as was total movement time (37 vs 50 minutes respectively), whereas feeding was 3.7 times more frequent in the bed-sharing group than the cot-sleeping group. Bed-share infants without known risk factors for sudden infant death syndrome (SIDS) experience increased maternal touching and looking, increased breastfeeding, and faster and more frequent maternal responses. This high level of interaction is unlikely to occur if maternal arousal is impaired, for example, by alcohol or overtiredness. Increased head covering and side sleep position occur during bed-sharing, but whether these factors increase the risk of SIDS, as they do in cot sleeping, requires further investigation.

Infant sleep, parental sleep and parenting stress in families of mothers on maternity leave and in families of working mothers.

PubMed

Sinai, Dana; Tikotzky, Liat

2012-04-01

The purpose of the present study was to investigate the links between infants' sleep and their parents' sleep and to assess the links between infant/parent sleep and parenting stress. Furthermore, we explored whether the links between sleep and parenting stress are moderated by maternal leave status. Participants were 50 families with an infant between the ages of 4-5 months. Half of the mothers were on maternity leave while the others returned to work. Parents completed daily sleep logs about infants' and their own sleep for 4 consecutive nights. Each parent also completed the Parenting Stress Index. Infant sleep was associated with sleep of both mothers and fathers, but the correlations with maternal sleep were stronger. Parental perceptions of their infant's sleep as problematic were associated with higher parenting stress. Poorer infant and maternal sleep patterns were associated with parenting stress only in families with mothers on maternity leave, probably because these mothers need to provide intensive caregiving "around the clock" without sufficient opportunities to rest.

To examine: (1) the prevalence and characteristics of bed-sharing among non-Hispanic Black and White infants in Georgia, and (2) differences in bed-sharing and sleep position behaviors prior to and after the American Academy of Pediatrics' 2005 recommendations against bed-sharing. Georgia Pregnancy Risk Assessment Monitoring System (PRAMS) data were obtained from the Georgia Department of Public Health. Analysis was guided by the socioecological model levels of: Infant, Maternal, Family, and Community/Society within the context of race. Data from 2004 to 2011 were analyzed to address the first objective and from 2000 to 2004 and 2006 to 2011 to address the second objective. Rao-Scott Chi square tests and backward selection unconditional logistic regression models for weighted data were built separately by race; odds ratios (OR) and 95 % Confidence Intervals (CIs) were calculated. A total of 6595 (3528 Black and 3067 White) cases were analyzed between 2004 and 2011. Significantly more Black mothers (81.9 %) reported "ever" bed-sharing compared to White mothers (56 %), p < 0.001. Logistic regression results indicated that the most parsimonious model included variables from all socioecological levels. For Blacks, the final model included infant age, pregnancy intention, number of dependents, and use of Women, Infant and Children (WIC) Services. For Whites, the final model included infant age, maternal age, financial stress, partner-related stress, and WIC. When comparing the period 2000-2004 to 2006-2011, a total of 10,015 (5373 Black and 4642 White cases) were analyzed. A significant decrease in bedsharing was found for both Blacks and Whites; rates of non-supine sleep position decreased significantly for Blacks but not Whites. Continued high rates of bed-sharing and non-supine sleep position for both Blacks and Whites demonstrate an ongoing need for safe infant sleep messaging. Risk profiles for Black and White mothers differed, suggesting the importance of tailored messaging. Specific research and practice implications are identified and described.

2016-09-01

Objectives (1) Determine the prevalence of maternal trust in advice sources on infant care practices; (2) Investigate the association of maternal and infant characteristics with trust in advice sources on infant care practices. Methods Using probability sampling methods, we recruited mothers from 32 U.S. maternity hospitals with oversampling of Black and Hispanic women resulting in a nationally representative sample of mothers of infants aged 2-6 months. Survey questions assessed maternal trust in advice sources (physicians, nurses, family, friends, and media) regarding infant care practices including infant sleep practices (sleep position, bed sharing, and pacifier use), feeding, and vaccination. Weighted frequencies of maternal trust in advice sources were calculated to obtain prevalence estimates. Multivariable logistic regression was used to assess the association of maternal and infant characteristics with maternal trust in advice sources. Results Mothers had the greatest trust in doctors for advice on all infant care practices (56-89 %), while trust was lowest for friends (13-22 %) and the media (10-14 %). In the adjusted analyses, there were significant associations of maternal race/ethnicity, education, and age with trust in advice sources. Conclusions for Practice Maternal trust in advice about infant care practices varied significantly by source. A better understanding of which advice sources are most trusted by mothers, as well as the factors associated with maternal trust, may guide the development of more effective strategies to improve adherence to health promoting infant care practices.

Resting-state fMRI in sleeping infants more closely resembles adult sleep than adult wakefulness

Resting state functional magnetic resonance imaging (rs-fMRI) in infants enables important studies of functional brain organization early in human development. However, rs-fMRI in infants has universally been obtained during sleep to reduce participant motion artifact, raising the question of whether differences in functional organization between awake adults and sleeping infants that are commonly attributed to development may instead derive, at least in part, from sleep. This question is especially important as rs-fMRI differences in adult wake vs. sleep are well documented. To investigate this question, we compared functional connectivity and BOLD signal propagation patterns in 6, 12, and 24 month old sleeping infants with patterns in adult wakefulness and non-REM sleep. We find that important functional connectivity features seen during infant sleep closely resemble those seen during adult sleep, including reduced default mode network functional connectivity. However, we also find differences between infant and adult sleep, especially in thalamic BOLD signal propagation patterns. These findings highlight the importance of considering sleep state when drawing developmental inferences in infant rs-fMRI. PMID:29149191

However, rs-fMRI in infants has universally been obtained during sleep to reduce participant motion artifact, raising the question of whether differences in functional organization between awake adults and sleeping infants that are commonly attributed to development may instead derive, at least in part, from sleep. This question is especially important as rs-fMRI differences in adult wake vs. sleep are well documented. To investigate this question, we compared functional connectivity and BOLD signal propagation patterns in 6, 12, and 24 month old sleeping infants with patterns in adult wakefulness and non-REM sleep. We find that important functional connectivity features seen during infant sleep closely resemble those seen during adult sleep, including reduced default mode network functional connectivity. However, we also find differences between infant and adult sleep, especially in thalamic BOLD signal propagation patterns. These findings highlight the importance of considering sleep state when drawing developmental inferences in infant rs-fMRI.

To explore the perceptions and experiences of parental professional help-seeking for infant sleep and sleep-related concerns. Infant sleep is a frequent concern for parents. However, very little is known about the reasons parents seek, do not seek or delay seeking professional attention about their concerns related to infant sleep. A qualitative study design was used. Twenty audio-taped interviews with parents of healthy 12-month-old infants were conducted at a university-affiliated hospital or parents' homes depending on where parents felt more comfortable discussing their personal views and medical help-seeking experiences. Thematic content analysis was performed to determine specific patterns and similarities within and between interview data. Three main themes developed from the interviews were as follows: (i) uncertainty about infant sleep; (ii) I can handle infant sleep; and (iii) I am not satisfied with the professional services provided for infant sleep. Overall, parents knew little about or misunderstood infant sleep behaviours. Lack of proper information and knowledge about infant sleep influenced parents' motivation for professional help-seeking and help-receiving. Parents who have consulted a healthcare professional but received unsatisfactory responses, such as an ambivalent attitude or insufficient assessment, reported being less motivated or unwilling to seek medical help again. Our study demonstrates the complexity of parental professional help-seeking and receiving for infant sleep. Findings suggest that parents perceive a wide range of barriers that influence the likelihood that they will seek professional advice for infant sleep. Reducing knowledge barriers and providing adequate attention at all well-infant visits would facilitate parental use of healthcare services to manage problematic infant sleep behaviours. © 2017 John Wiley & Sons Ltd.

Goodness of fit between prenatal maternal sleep and infant sleep: Associations with maternal depression and attachment security.

The current study prospectively examined the ways in which goodness of fit between maternal and infant sleep contributes to maternal depressive symptoms and the mother-child relationship across the first years of life. In a sample of 173 mother-child dyads, maternal prenatal sleep, infant sleep, maternal depressive symptoms, and mother-child attachment security were assessed via self-report, actigraphy, and observational measures. Results suggested that a poor fit between mothers' prenatal sleep and infants' sleep at 8 months (measured by sleep diary and actigraphy) was associated with maternal depressive symptoms at 15 months. Additionally, maternal depression mediated the association between the interplay of mother and infant sleep (measured by sleep diary) and mother-child attachment security at 30 months. Findings emphasize the importance of the match between mother and infant sleep on maternal wellbeing and mother-child relationships and highlight the role of mothers' perceptions of infant sleep.

Exploring Maternal Perceptions of Infant Sleep and Feeding Method Among Mothers in the United Kingdom: A Qualitative Focus Group Study.

2016-01-01

In a context with strong rhetorical support for breastfeeding in the health system, yet extremely low rates of breastfeeding after hospital discharge, U.K. women's decisions about infant feeding reflect the reality of competing priorities in their lives, including obtaining adequate sleep. Popular wisdom in the U.K. tightly links breastfeeding and inadequate night-time sleep. Mothers are advised by peers and family to introduce formula or solid foods to infants to promote longer sleep. The first objective of this study was to investigate women's understandings of the nature of infant sleep and their perceptions of links between infant feeding method and sleep. The second was to explore how these perceptions influence infant feeding and sleep practices. Underpinning our work is the understanding that infant care choices result from trade-offs by which mothers strive to balance infant- and self-care. We conducted seven focus groups with mothers of infants in two regions of the U.K. Verbatim transcripts were thematically coded and emergent themes were identified. We found clearly diverging narratives between breastfeeding and formula-feeding mothers. Breastfeeding mothers viewed the fragmentary nature of infant sleep as natural, while mothers who were formula feeding felt this was a problem to be fixed. The strategies used to promote infant and maternal sleep in each group were aligned with their underlying perception of how infant sleep works. Maternal perceptions of the nature of infant sleep and its relation to infant feeding method impact infant care practices in the first year of life.

Mother-infant bed-sharing has been associated with a higher risk of sleep-related infant deaths, which affects African Americans at a disproportionately higher rate. Although "separate but proximate sleep surfaces" for infants has been recommended since 2005, bed-sharing remains a common practice, especially among African Americans. This study examined factors associated with bed-sharing among African American and White mothers. Separate logistic regression models were constructed for African American and White respondents to the 2007-2010 Wisconsin Pregnancy Risk Assessment and Monitoring System. The sample consisted of 806 African Americans and 1,680 Whites (N = 2,486). A significantly larger proportion of African Americans (70.6 %) reported bed-sharing than Whites (53.4 %). For both races, partner-related stress was significantly associated with bed-sharing; no significant differences were found between the two racial groups. For African Americans, partner stress (OR 1.8: 1.2-2.6) and maternal education of 13-15 years (OR 2.0: 1.2-3.4) or ≥16 years (OR 2.7: 1.1-6.3) was associated with increased odds of bed-sharing. For Whites, partner stress (OR 1.3: 1-1.8), breastfeeding (OR 2.5: 1.9-3.1), income of $35,000-$49,999 (OR 1.6: 1.2-2.3), being unmarried (OR 1.5: 1.1-2.2), needing money for food (OR 1.6: 1.1-2.3), and non-supine sleep (OR 1.8: 1.2-2.6) were associated with increased odds of bed-sharing. Differences were found in bed-sharing factors between racial groups which suggests a need for culturally-relevant, tailored safe infant sleep interventions. Providers should ask families about their infant's sleeping environment and address safety issues within that environment. More research is needed on the context and reasons for bed-sharing.

Infant sleep and paternal involvement in infant caregiving during the first 6 months of life.

Tikotzky, Liat; Sadeh, Avi; Glickman-Gavrieli, Tamar

2011-01-01

The goals of this study were to assess: (a) the involvement of fathers and mothers in overall and nighttime infant caregiving; (b) the links between paternal involvement in infant care and infant sleep patterns during the first 6 months. Fifty-six couples recruited during their first pregnancy, participated in the study. After delivery (1 and 6 months), both parents completed a questionnaire assessing the involvement of fathers relative to mothers in infant caregiving. Infant sleep was assessed using actigraphy and sleep diaries. Mothers were significantly more involved than fathers in daytime and nighttime caregiving. A higher involvement of fathers in overall infant care predicted and was associated with fewer infant night-wakings and with shorter total sleep time after controlling for breastfeeding. The findings highlight the importance of including fathers in developmental sleep research. Future studies should explore mechanisms underlying the relations between paternal involvement and infant sleep.

Bidirectional associations between bedtime parenting and infant sleep: Parenting quality, parenting practices, and their interaction.

In keeping with transactional conceptualizations of infant sleep development (Sadeh, Tikotzky, & Scher, 2010), the present study was an examination of longitudinal, bidirectional linkages between bedtime parenting (through direct observations of parenting practices and quality) and infant sleep across the first 6 months postpartum. In doing so, we also drew from Darling and Steinberg's (1993) conceptual model to examine parenting quality as a moderator of linkages between specific bedtime practices and infant sleep. Multilevel model analyses revealed that the strongest increases in infant nighttime sleep across the first 6 months occurred among infants of mothers who engaged in low levels of nursing at bedtime. Within-person linkages between mothers' emotional availability (EA) at bedtime, infant distress, and infant sleep were found, such that at time points when mothers were more emotionally available, infants were less distressed and slept more throughout the night. Several moderating effects of maternal EA on linkages between parenting practices and infant sleep were obtained that were consistent with predictions from Darling and Steinberg (1993). Higher maternal EA in combination with less close contact at bedtime was associated with more infant sleep across the night on average, and higher EA in combination with fewer arousing bedtime activities predicted more rapid increases in infant sleep with age. Finally, there was evidence of infant-driven effects, as higher infant nighttime distress predicted lower EA at subsequent time points. Results showcased the complex, reciprocal interplay between parents and infants in the development of infant sleep patterns and parenting behavior during the first 6 months postpartum.

The focus of this article is on sleep duration and sleep problems in infants and their association with body weight. A retrospective birth cohort of 519 infants was enrolled in a community-based study conducted in Changsha, China. Infant weight and other health-related information were collected during regular standard checkups at the Community Health Service Centers when infants were 1, 3, 6, 8, and 12 months old. The sleep duration and sleep problems of infants were assessed by maternal self-reports. Panel data model was used to evaluate the association of sleep duration and sleep problems with infant body weight. Significant relevance between self-reported sleep duration and weight of infants has been reported in the literature tested by the fixed effects model (p < 0.01). However, this study indicated that sleep problems of infants had no effect on their weight (p = 0.151), after adjusting feeding patterns and socioeconomic factors of their families. This paper argues that, as a potentially modifiable risk factor, infant sleep duration deserves more attention from their parents and families in order to prevent and control overweight or obesity in infants as well as reducing the incidence of obesity in adults.

To identify evidence available in the literature about sleep patterns of infants attending nurseries. An integrative review of studies published in Portuguese, English or Spanish available in full text on LILACS, CINAHL, and PubMed databases. The following descriptors sono, lactente and creches or berçários (in Portuguese) and sleep, infant and childcare or nurseries were used for LILACS, CINAHL and Pubmed, respectively. Nine studies were selected and analyzed. The main component explored in the studies about sleep pattern is the sleep position of the infants, due to its association with sudden infant death syndrome. The results pointed to the need to promote and develop written guidelines regarding behavioral practices to reduce the risk of this phenomenon. Evidence has identified sleep issues, mainly regarding the sleep position of the infant and the environment where the infant sleeps, showing that it is critical to set routines and interventions to improve the quality of sleep care of infants attending nurseries.

Initial studies indicate more independent and consolidated sleep in the first few months in infants who sleep separately. Little is known, however, about the relationship of sleep location (separate room, room-sharing, bed-sharing) with sleep outcomes in older infants (ages 6-12 months). It was expected that those who sleep in a separate room would have better parent-perceived sleep outcomes and more positive sleep health behaviors. Parents of 6236 infants (6-12 months) in the United States (US) and 3798 in an international sample (Australia, Brazil, Canada, Great Britain, and New Zealand) completed a smartphone app-based expanded version of the validated Brief Infant Sleep Questionnaire. A total of 37.2% of the infants in the US and 48.4% in the international sample slept in a separate room. In both samples, infants who slept in a separate room as opposed to room-sharing or bed-sharing had parent-perceived sleep outcomes and sleep-related behaviors that reflected earlier bedtimes, shorter time to fall asleep, more nighttime and total sleep, and increased sleep consolidation. They were also more likely to have a consistent bedtime routine and to fall asleep independently, as well as less likely to feed to sleep at bedtime and during the night. In addition, parents of separate room sleepers perceived bedtime to be less difficult and sleep to be better overall. Overall, 6- to 12-month-old infants who slept in a separate room had better reported sleep outcomes and fewer parent-perceived disturbances at bedtime than infants who room-shared with their parents, as well compared to those who slept in their parents' bed.

Kelmanson, I A; Adulas, E I

2004-01-01

The study aimed at assessing possible relationship between the quality of infant environment and maternal reported behavioural features during sleep in 2-month-old infants. It comprised 115 randomly selected, apparently healthy infants (50 boys, 65 girls) from community setting who were singletons born at term with normal birth weight in St. Petersburg in 2001-2002. Quality of infant care was estimated using the "PROCESS" (Paediatric Review of Children's Environment Support and Stimulation) inventory enabling to measure infant's developmental stimulation and organisation. Infant's behaviour during sleep was assessed using an adapted version of the Children's Sleep Habits Questionnaire (CSHQ). The babies facing more developmental stimulation and from more organised environment less often fell asleep in parents bed (P = 0.036). Infants from more organised environment were more often put to sleep at the same time at night, more often were ready to go to sleep at bedtime and less often struggled at bed; it was more common with them to have right amount of sleep and to have about a same amount of sleep each day; less often they moved a lot during sleep and woke up in sleep. These associations remained significant after adjustment has been made for each of such potential confounders as infant's gender, weight at birth and at study, gestational age, Apgar score at 1 and 5 minutes, birth order, maternal age and education, maternal marital status, infant's feeding at birth and at study, as well as to their simultaneous effects. Lower environmental organisation and developmental stimulation may be associated with specific disadvantageous infant behavioural features during sleep. Infants with parentally reported sleep problems should be carefully considered for possible flaws in the quality of environment.

The purpose of this study was to examine sleep patterns in a large sample of infants and toddlers (ages birth to 36 months) in Korea, and to compare sleep patterns, sleep problems, sleep ecology, and parental behaviors to global sleep data on young children in both predominantly Asian (P-A) and predominantly Caucasian (P-C) countries/regions. We additionally examined parent and child demographic information, parental behaviors, and aspects of the sleep ecology as predictors of sleep patterns among infants and toddlers in Korea. Parents/caregivers of 1,036 Korean infants and toddlers completed an expanded, internet-based version of the brief infant sleep questionnaire. Consistent with other studies of sleep in early childhood, sleep/wake patterns became increasingly consolidated with older child age for the Korea sample. Compared to both P-A and P-C infants and toddlers, children in Korea had the latest bedtimes, shortest total sleep and daytime sleep durations, and the least frequent rates of napping. Even though half of parents perceive their children's sleep problematic, parental perceptions of severe child sleep problems were the lowest. Within Korea, breastfeeding and bottle-feeding at sleep resumption were associated with increased nocturnal awakenings. Evening television viewing was associated with later bedtimes, which may have implications for sleep hygiene recommendations in clinical practice. The current study provides important information about sleep/wake patterns, parental behaviors, and aspects of the sleep ecology for infants and toddlers for physicians to support healthy sleep in Korea.

The aim of the study was to assess the relationship of sleep with mood and development in infancy. Mothers of 1351 mothers of infants (ages 3-13 months) in Brazil completed an internet-based expanded version of the Brief Infant Sleep Questionnaire and the Ages & Stages Questionnaire. Overall, there were associations among parental ratings of infants' bedtime, morning, and daytime mood with sleep outcomes, especially sleep fragmentation, duration of nighttime sleep, and parental perception of sleep problems. There were no relationships between any sleep variables and developmental outcomes, including communication, fine and gross motor skills, problem-solving, and personal social relationships. Overall, these results indicate that sleep patterns and sleep problems during infancy are associated with parental ratings of infant mood but not more global developmental outcomes.

This prospective repeated-measures study explored potential factors (postmenstrual age, body weight, gender, chronological age, illness severity, and circadian rhythm) related to preterm infants' circadian sleep/wake patterns. Circadian sleep/wake patterns were measured using an Actiwatch for 3 continuous days in preterm infants (gestational age of 28-36.4 weeks) in a neonatal intensive care unit and hospital nursery. Potential factors associated with circadian sleep/wake patterns were analyzed using the generalized estimating equation. For our sample of 30 preterm infants, better sleep/wake patterns were associated with male gender, younger postmenstrual and chronological age, lower body weight, and less illness severity. Preterm infants' total sleep time ( B = 41.828, p < .01) and percentage of sleep time ( B = 3.711, p < .01) were significantly longer at night than during the day. These findings can help clinicians recognize preterm infants' sleep problems, signaling the need to provide individualized support to maintain these infants' sleep quality during their early life.

This study described how parents perceived their own sleep, and their infants', during neonatal intensive care unit (NICU) admission and after discharge. It also explored the infants' sleeping location at home. The study was conducted in the NICUs of two Swedish university hospitals. The parents of 86 infants - 86 mothers and 84 fathers - answered questionnaires during their infants' hospital stay, at discharge and at the infants' corrected ages of two, six and 12 months. The parents' own sleep was explored with the Insomnia Severity Index. Mothers reported more severe insomnia than fathers during their infants' hospitalisation, and these higher insomnia severity scores were associated with more severe infant sleep problems at discharge (p = 0.027) and at two months (p = 0.006) and 12 months (p = 0.002) of corrected age. During the study period, 4%-10% of the parents reported severe or very severe infant sleeping problems. The bed-sharing rate was 75% after discharge and about 60% at the corrected age of 12 months. Maternal insomnia during an infant's hospital stay was associated with later perceptions of sleep problems in their children. Parents need support to find solutions for optimal sleep without seeing their child's sleeping patterns as a problem. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Unobtrusive sleep state measurements in preterm infants - A review.

Werth, Jan; Atallah, Louis; Andriessen, Peter; Long, Xi; Zwartkruis-Pelgrim, Elly; Aarts, Ronald M

2017-04-01

Sleep is important for the development of preterm infants. During sleep, neural connections are formed and the development of brain regions is triggered. In general, various rudimentary sleep states can be identified in the preterm infant, namely active sleep (AS), quiet sleep (QS) and intermediate sleep (IS). As the infant develops, sleep states change in length and organization, with these changes as important indicators of brain development. As a result, several methods have been deployed to distinguish between the different preterm infant sleep states, among which polysomnography (PSG) is the most frequently used. However, this method is limited by the use of adhesive electrodes or patches that are attached to the body by numerous cables that can disturb sleep. Given the importance of sleep, this review explores more unobtrusive methods that can identify sleep states without disturbing the infant. To this end, after a brief introduction to preterm sleep states, an analysis of the physiological characteristics associated with the different sleep states is provided and various methods of measuring these physiological characteristics are explored. Finally, the advantages and disadvantages of each of these methods are evaluated and recommendations for neonatal sleep monitoring proposed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Nighttime Parenting Strategies and Sleep-Related Risks to Infants

2012-01-01

A large social science and public health literature addresses infant sleep safety, with implications for infant mortality in the context of accidental deaths and Sudden Infant Death Syndrome (SIDS). As part of risk reduction campaigns in the USA, parents are encouraged to place infants supine and to alter infant bedding and elements of the sleep environment, and are discouraged from allowing infants to sleep unsupervised, from bed-sharing either at all or under specific circumstances, or from sofa-sharing. These recommendations are based on findings from large-scale epidemiological studies that generate odds ratios or relative risk statistics for various practices; however, detailed behavioural data on nighttime parenting and infant sleep environments are limited. To address this issue, this paper presents and discusses the implications of four case studies based on overnight observations conducted with first-time mothers and their four-month old infants. These case studies were collected at the Mother-Baby Behavioral Sleep Lab at the University of Notre Dame USA between September 2002 and June 2004.Each case study provides a detailed description based on video analysis of sleep-related risks observed while mother-infant dyads spent the night in a sleep lab. The case studies provide examples of mothers engaged in the strategic management of nighttime parenting for whom sleep-related risks to infants arose as a result of these strategies. Although risk reduction guidelines focus on eliminating potentially risky infant sleep practices as if the probability of death from each were equal, the majority of instances in which these occur are unlikely to result in infant mortality. Therefore, we hypothesise that mothers assess potential costs and benefits within margins of risk which are not acknowledged by risk-reduction campaigns. Exploring why mothers might choose to manage sleep and nighttime parenting in ways that appear to increase potential risks to infants may help illuminate how risks occur for individual infants.

Hairston, Ilana S.; Waxler, Ellen; Seng, Julia S.; Fezzey, Amanda G.; Rosenblum, Katherine L.; Muzik, Maria

2011-01-01

Introduction: Children of parents who experienced trauma often present emotional and behavioral problems, a phenomenon named inter-generational transmission of trauma (IGTT). Combined with antenatal factors, parenting and the home environment contribute to the development and maintenance of sleep problems in children. In turn, infant sleep difficulty predicts behavioral and emotional problems later in life. The aim of this study was to investigate whether infant sleep problems predict early behavioral problems indicative of IGTT. Methods: 184 first-time mothers (ages 18–47) participated. N = 83 had a history of childhood abuse and posttraumatic stress disorder (PTSD+); 38 women reported childhood abuse but did not meet diagnostic criteria for PTSD (PTSD−); and the control group (N = 63) had neither a history of abuse nor psychopathology (CON). Depression, anxiety, and sleep difficulty were assessed in the mothers at 4 months postpartum. Infant sleep was assessed using the Child Behavior Sleep Questionnaire (CSHQ). Outcome measures included the Parent Bonding Questionnaire (PBQ) at 4 months and the Child Behavior Check List (CBCL) at 18 months. Results: Infants of PTSD+ mothers scored higher on the CSHQ and had more separation anxiety around bedtime than PTSD− and CON, and the severity of their symptoms was correlated with the degree of sleep disturbance. Maternal postpartum depression symptoms mediated impaired mother-infant bonding, while infant sleep disturbance contributed independently to impaired bonding. Mother-infant bonding at 4 months predicted more behavioral problems at 18 months. Conclusions: Infant sleep difficulties and maternal mood play independent roles in infant-mother bonding disturbance, which in turn predicts behavioral problems at 18 months.

Lampl, Michelle; Johnson, Michael L.

2011-01-01

Study Objectives: The mechanisms underlying infant sleep irregularity are unknown. This study tests the hypothesis that sleep and episodic (saltatory) growth in infant length are temporally coupled processes. Study design: Daily parental diaries continuously recorded sleep onset and awakening for 23 infants (14 females) over 4-17 months (n = 5798 daily records). Multiple model-independent methods compared day-to-day sleep patterns and saltatory length growth. Measurements and Results: Approximate entropy (ApEn) quantified temporal irregularity in infant sleep patterns; breastfeeding and infant sex explained 44% of inter-individual variance (P = 0.001). Random effects mixed-model regression identified that saltatory length growth was associated with increased total daily sleep hours (P < 0.001) and number of sleep bouts (P = 0.001), with breastfeeding, infant sex, and age as covariates. Infant size and illness onset were non-contributory. CLUSTER analysis identified peaks in individual sleep of 4.5 more h and/or 3 more naps per day, compared to intervening intervals, that were non-randomly concordant with saltatory length growth for all individuals (P < 0.05), with a time lag of 0-4 days. Subject-specific probabilities of a growth saltation associated with sleep included a median odds ratio of 1.20 for each additional hour (n = 8, 95% CI 1.15 to 1.29) and 1.43 for each additional sleep bout (n = 12, 95% CI 1.21-2.03). Increased sleep bout duration predicted weight (P < 0.001) and abdominal skinfold accrual (P = 0.05) contingent on length growth, and truncal adiposity independent of growth (P < 0.001). Conclusions: Sleeping and length growth are temporally related biological processes, suggesting an integrated anabolic system. Infant behavioral state changes may reflect biological mechanisms underlying the timing and control of human growth. Citation: Lampl M; Johnson ML.

Crawford, Doreen

2017-05-09

Sleep is a biological necessity. Infants are unique individuals and what can be regarded as normal for one infant and his or her family may be considered a problem for another. Genetics, lifestyles, roles and responsibilities all influence sleep. This article explores the physiology of infant sleep and reviews how sleep is influenced by culture, events such as a hospital admission and parenting styles. It considers how the children's nurse can help and support a family who may feel that they have infant sleep-related issues. A good sleep pattern is essential for a child to succeed at school, reach their full potential and maintain their health and well-being.

Oxygen saturation, periodic breathing, and sleep apnea in infants aged 1-4 months old living at 3200 meters above sea level.

To describe, in infants aged 1-4 months old living at 3200 meters above sea level (MASL), oxygen saturation (SpO2), sleep apnea indices, and periodic breathing (PB) during sleep. Polysomnographies were done in 18 healthy infants. The median SpO2 was 87%, and the median PB was 7.2% for the total sleep time. The median central sleep apnea index was 30.5/hour, which decreased to 5.4/hour once sleep apneas associated with PB were excluded. The 5th percentile for SpO2 was 76% among awake infants, and 66% among asleep infants. The SpO2 was lower than that observed at sea level, whereas PB and the central sleep apnea index were higher, once sleep apneas associated with PB were excluded. The latter was similar to that observed at sea level. At 3200 MASL, different cut-off points are required for a normal SpO2, one for infants during the waking state and one for infants during sleep.

Housing influences among sleep-related infant injury deaths in the USA.

Chu, Tracy; Hackett, Martine; Kaur, Navpreet

2016-06-01

This article examines the role of housing conditions in sleep-related infant injury death, a leading cause of infant mortality in the USA. The use of an unsafe sleep surface is a major risk factor for sleep-related infant injury. This exploratory study examined contextual circumstances, specifically those related to the physical environment, which may contribute to caregivers' decisions to place an infant on an unsafe sleep surface. It employed a retrospective review of 255 sleep-related infant injury death cases in a large urban area from 2004 to 2010 where an infant was found sleeping on an unsafe sleep surface, including 122 cases where a crib or bassinet was identified in the home. Quantitative findings indicated no differences in demographic or risk characteristics between infants with cribs or bassinets and those without them. Qualitative findings suggested the lack of crib or bassinet use may be related to environmental factors influenced by poverty, specifically crowded living space, room temperature and vermin infestation. This study suggests that infants may be at risk of sleep-related injury deaths even when a crib or bassinet is present in the home and supports the consideration of housing conditions in health promotion efforts to reduce infant mortality. Understanding environmental factors that may contribute to infants sleeping on an unsafe surface can help maternal child health and public health professionals develop more appropriate interventions that address deleterious living conditions. © The Author 2015.

Arousal from sleep pathways are affected by the prone sleeping position and preterm birth: preterm birth, prone sleeping and arousal from sleep.

PubMed

Richardson, Heidi L; Horne, Rosemary S C

2013-09-01

Preterm infants exhibit depressed arousability from sleep when compared with term infants. As the final cortical element of the arousal process may be the most critical for survival, we hypothesized that the increased vulnerability of preterm infants to the Sudden Infant Death Syndrome (SIDS) could be explained by depressed cortical arousal (CA) responses. We evaluated the effects of preterm birth on stimulus-induced arousal processes in both the prone and supine sleeping positions. 10 healthy preterm infants were studied with daytime polysomnography, in both supine and prone sleeping positions, at 36 weeks gestational age, 2-4 weeks, 2-3 months and 5-6 months post-term corrected age. Sub-cortical activations and cortical arousals (CA) were expressed as proportions of total arousal responses. Preterm data were compared with data from 13 healthy term infants studied at the same corrected ages. In preterm infants increased CAs were observed in the prone position at all ages studied. Compared to term infants, preterm infants had significantly fewer CAs in QS when prone at 2-3 months of age and more CAs when prone at 2-4 weeks in AS. There were no differences in either sleep state when infants slept supine. Prone sleeping promoted CA responses in healthy preterm infants throughout the first six months of post-term age. We have previously suggested that in term infants enhanced CA represents a critical protection against a potentially harmful situation; we speculate that for preterm-born infants the need for this protection is greater than in term infants.

Asaka, Yoko; Takada, Satoshi

2013-08-01

The aim of this study was to compare infants' sleep measures through an actigraph and maternal parenting stress among preterm and full-term mothers, and to explore the factors affecting maternal parenting stress in relation to infants' sleep. The subjects were 44 pairs of mothers and children. Twenty-one were in the preterm group, and 23 were in the full-term group. Inclusion criteria for preterm infants were born at less than 36 weeks and birthweight of less than 2500 g. The Parenting Stress Index (PSI) Short Form assesses maternal perception of the degree of parenting stress: the children's domain, and the parent's domain. An actigraph was applied to assess the infants' sleep measures. The PSI showed significant differences, with high scores in parenting stress in the preterm group. Also, the number of mothers who complained about their infant's sleep issues was significantly higher in the preterm group. Most of the sleep measures showed improvement by their age in both preterm and full-term infants. Multiple linear regression analysis showed that sleep efficiency, longest sleep duration at nighttime accounted for 71% of stress in the children's domain of the PSI of the preterm group. The parenting stress among mothers of preterm infants was significantly higher than that of mothers of full-term infants. The mothers of preterm infants were concerned about their infant's nocturnal sleep quality. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

Infant Sleep After Immunization: Randomized Controlled Trial of Prophylactic Acetaminophen

PubMed Central

Gay, Caryl L.; Lynch, Mary; Lee, Kathryn A.

2011-01-01

OBJECTIVE: To determine the effects of acetaminophen and axillary temperature responses on infant sleep duration after immunization. METHODS: We conducted a prospective, randomized controlled trial to compare the sleep of 70 infants monitored by using ankle actigraphy for 24 hours before and after their first immunization series at ∼2 months of age. Mothers of infants in the control group received standard care instructions from their infants' health care provider, and mothers of infants in the intervention group were provided with predosed acetaminophen and instructed to administer a dose 30 minutes before the scheduled immunization and every 4 hours thereafter, for a total of 5 doses. Infant age and birth weight and immunization factors, such as acetaminophen use and timing of administration, were evaluated for changes in infant sleep times after immunization. RESULTS: Sleep duration in the first 24 hours after immunization was increased, particularly for infants who received their immunizations after 1:30 pm and for those who experienced elevated temperatures in response to the vaccines. Infants who received acetaminophen at or after immunization had smaller increases in sleep duration than did infants who did not. However, acetaminophen use was not a significant predictor of sleep duration when other factors were controlled. CONCLUSIONS: If further research confirms the relationship between time of day of vaccine administration, increased sleep duration after immunization, and antibody responses, then our findings suggest that afternoon immunizations should be recommended to facilitate increased sleep in the 24 hours after immunization, regardless of acetaminophen administration.

Sleep complaints are common amongst mothers of infants and insufficient, inefficient or fragmented sleep is associated with postnatal depression. The aim of this review is to determine whether psychosocial sleep-focused interventions offered in the perinatal period improve infant sleep or maternal mood. We searched PubMed, PsycInfo, EMBASE and CINAHL with no date restriction. We reviewed 1097 articles, resulting in nine papers (n = 1,656) that fit the eligibility criteria for inclusion in the analyses. The primary outcome was infant sleep, defined as maternal reports of infant nocturnal total sleep time and number of night-time wakes. The secondary outcome was maternal mood. The meta-analysis indicated improvements in reported infant nocturnal total sleep time (Hedge's g = 0.204, p < 0.01). However, there was no evidence for reducing infant night wakes (Hedge's g = 0.103, p = 0.134). There was evidence of maternal mood improvements (Hedge's g = 0.152, p = 0.014), however, this could have been influenced by publication bias. Psychosocial sleep interventions appear to impact the amount of sleep that a mother reports her baby to have, although the infants continue to wake as frequently. More research is needed to confirm whether sleep-related improvements can translate into improvements in maternal mood. Copyright © 2015 Elsevier Ltd. All rights reserved.

2016-01-01

BACKGROUND AND OBJECTIVE: Reports describing factors associated with sleep-related infant death rely on caregiver report or postmortem findings. We sought to determine the frequency of environmental risk factors by using nocturnal sleep videos of infants. METHODS: Healthy, term newborns were recruited for a parent study examining the role of parenting in the development of nighttime infant sleep patterns. For 1 night at ages 1, 3, and 6 months, video recordings were conducted within family homes. Videos were coded for sudden infant death syndrome risk factors in post hoc secondary analyses after the parent study was completed. RESULTS: Among 160 one-month-olds, initially 21% were placed to sleep on nonrecommended sleep surfaces and 14% were placed nonsupine; 91% had loose/nonapproved items on their sleep surface, including bedding, bumper pads, pillows, stuffed animals, and sleep positioners. Among 151 three-month-olds, 10% were initially placed on a nonrecommended sleep surface, 18% were placed nonsupine, and 87% had potentially hazardous items on their sleep surface. By 6 months, 12% of the 147 infants initially slept on a nonrecommended surface, 33% were placed to bed nonsupine, and 93% had loose/nonrecommended items on their surface. At 1, 3, and 6 months, 28%, 18%, and 12% changed sleep locations overnight, respectively, with an increased likelihood of bed-sharing and nonsupine position at the second location at each time point. CONCLUSIONS: Most parents, even when aware of being recorded, placed their infants in sleep environments with established risk factors. If infants were moved overnight, the second sleep environment generally had more hazards. PMID:27527797

Coparenting Quality During the First Three Months After Birth: The Role of Infant Sleep Quality

The transition to parenthood can be stressful for new parents, as parents must learn to take on new roles and responsibilities. Sleep disruption—which has been linked in prior research to parent distress and fatigue—is common in the early months. The current study is the first to our knowledge to examine infant sleep and its potential indirect influence on parents’ perceptions of coparenting quality at 1 and 3 months of infant age. Participants included 150 families. Mothers reported more night waking, poorer sleep quality, more depressive symptoms, and worse perceptions of coparenting quality as compared with fathers. We tested a structural model of infant and parent night waking and sleep quality as predictors of parent distress and coparenting using maximum likelihood estimation. The frequency of infant night waking predicted father and mother night waking, which in turn predicted parent sleep quality. Poor parent sleep quality predicted elevated depressive symptoms, and finally depressive symptoms were negatively related to perceptions of coparenting quality. Significant indirect effects between infant night waking and parent depression and coparenting quality were found. In summary, both mothers’ and fathers’ perceptions of coparenting were related to the unfolding parental dynamics that take place surrounding infant sleep difficulties. This held true even after controlling for parent education, family income, and infant temperament. Therefore, parenting may indirectly benefit from interventions targeting infant sleep difficulties.

Power spectrum analysis of heart rate variability (HRV) is a noninvasive technique that provides a quantitative assessment of cardiovascular neural control. Using this technique, we studied the autonomic nervous system changes induced by sleep in 14 healthy subjects: 7 infants (mean age, 9.40 +/- 2.32 months) and 7 children (mean age, 8.93 +/- 0.65 years) during a standard all-night polysomnographic recording. Our primary aim was to assess the effect of sleep stage and age on short-term HRV during sleep in healthy infants and children. Power spectral density was estimated by autoregressive modeling over 250 consecutive R-R intervals. In this study, we mainly considered two spectral components: the high-frequency (HF) component (0.15 to 0.40 Hz), which reflects parasympathetic cardiovascular modulation; and the low-frequency (LF) component (0.04 to 0.15 Hz), generally considered due to both parasympathetic and sympathetic modulation. Heart rate was higher (p < 0.01 in all sleep stages) and total power lower (p < 0. 02) in infants than in children. HF power was higher in children than in infants (p < 0.05). In infants and children, the ratio between LF and HF powers changed with the various sleep stages (p < 0.02 in infants; p < 0.01 in children): it decreased during deep sleep and increased during rapid eye movement sleep. However, it was invariably lower in children than in infants. These findings show that the sleep stage and age both significantly influence short-term HRV during sleep in healthy infants and children. Hence, to provide unbiased results, HRV studies investigating the effects of age on autonomic nervous system activity should segment sleep into the five stages. In addition, despite a relatively small study sample, our data confirm greater parasympathetic control during sleep in children than in infants.

Sleep and ongoing cycling of sleep states are required for neurosensory processing, learning, and brain plasticity. Many aspects of neonatal intensive care environments such as handling for routine and invasive procedures, bright lighting, and noise can create stress, disrupt behavior, and interfere with sleep in prematurely born infants. The study empirically investigated whether a 30-minute observation of infant sleep states and behavior could differentiate an intervention to promote sleep in premature infants with feeding difficulties relative to conventional care (standard positioning, standard crib mattress [SP]). We included an intervention to determine the ability of the method to discriminate treatments and generate a benchmark for future improvements. The intervention, a conformational positioner (CP), is contoured around the infant to provide customized containment and boundaries. To more fully verify the 30-minute observational sleep results, standard polysomnography was conducted simultaneously and sleep outcomes for the 2 modalities were compared. In a randomized crossover clinical trial, 25 infants, 31.5 ± 0.6 weeks' gestational age and 38.4 ± 0.6 weeks at the study, with gastrointestinal conditions or general feeding difficulties used each intervention during an overnight neonatal intensive care unit sleep study. Infant sleep states and behaviors were observed during two 30-minute periods--that is, on the positioner and mattress--using the naturalistic observation of newborn behavior. Two certified developmental care nurses assessed sleep state, self-regulatory, and stress behaviors during 2-minute intervals and summed over 30 minutes. Sleep characteristics from standard polysomnography were measured at the time of behavior observations. Infants on CP spent significantly less time in alert, active awake, or crying states by observation compared with SP. Surgical subjects spent more time awake, active awake, or crying and displayed a higher number of behavior state changes than the nonsurgical infants. The percentage of time in observed deep sleep and quiet sleep was correlated with both percentage sleep efficiency (r = 0.78) and fewer state shifts per hour (r = -0.65) from electroencephalogram (EEG). Sleep efficiency by EEG was greater on CP versus SP. The CP enabled sleep compared with the standard mattress (SP) over 30-minute observation periods. Sleep status from behavioral observation was verified by standard EEG-based sleep techniques. Behavioral observation of sleep states may be a useful strategy for measuring the effectiveness of strategies to facilitate sleep in premature infants. Surgical subjects may benefit from additional interventions to promote sleep.

This study describes sleep patterns for mothers and fathers after the birth of their first child and compares exclusive breast-feeding families with parents who used supplementation during the evening or night at 3 months postpartum. As part of a randomized clinical trial, the study utilized infant feeding and sleep data at 3 months postpartum from 133 new mothers and fathers. Infant feeding type (breast milk or formula) was determined from parent diaries. Sleep was measured objectively using wrist actigraphy and subjectively using diaries. Lee's General Sleep Disturbance Scale was used to estimate perceived sleep disturbance. Parents of infants who were breastfed in the evening and/or at night slept an average of 40-45 minutes more than parents of infants given formula. Parents of infants given formula at night also self-reported more sleep disturbance than parents of infants who were exclusively breast-fed at night. Parents who supplement their infant feeding with formula under the impression that they will get more sleep should be encouraged to continue breast-feeding because sleep loss of more than 30 minutes each night can begin to affect daytime functioning, particularly in those parents who return to work.

Memory in 3-month-old infants benefits from a short nap.

A broad range of studies demonstrate that sleep has a facilitating role in memory consolidation (see Rasch & Born, ). Whether sleep-dependent memory consolidation is also apparent in infants in their first few months of life has not been investigated. We demonstrate that 3-month-old infants only remember a cartoon face approximately 1.5-2 hours after its first presentation when a period of sleep followed learning. Furthermore, habituation time, that is, the time to become bored with a stimulus shown repetitively, correlated negatively with the density of infant sleep spindles, implying that processing speed is linked to specific electroencephalographic components of sleep. Our findings show that without a short period of sleep infants have problems remembering a newly seen face, that sleep enhances memory consolidation from a very early age, highlighting the importance of napping in infancy, and that infant sleep spindles may be associated with some aspects of cognitive ability. © 2017 John Wiley & Sons Ltd.

To investigate whether sleep disturbances previously found to characterise high risk infants: (a) persist into childhood; (b) are influenced by early maternal settling strategies and (c) predict cognitive and emotional/behavioural functioning. Mothers experiencing high and low levels of psychosocial adversity (risk) were recruited antenatally and longitudinally assessed with their children. Mothers completed measures of settling strategies and infant sleep postnatally, and at 12 and 18 months, infant age. At five years, child sleep characteristics were measured via an actigraphy and maternal report; IQ and child adjustment were also assessed. Sleep disturbances observed in high-risk infants persisted at five years. Maternal involvement in infant settling was greater in high risk mothers, and predicted less optimal sleep at five years. Poorer five year sleep was associated with concurrent child anxiety/depression and aggression, but there was limited evidence for an influence of early sleep problems. Associations between infant/child sleep characteristics and IQ were also limited. Early maternal over-involvement in infant settling is associated with less optimal sleep in children, which in turn, is related to child adjustment. The findings highlight the importance of supporting parents in the early development of good settling practices, particularly in high-risk populations. Copyright © 2012 Elsevier B.V.

Infant sleep position practices 2 years into the "back to sleep" campaign.

2000-05-01

Since the 1992 American Academy of Pediatrics (AAP) recommendation to put babies to sleep in the nonprone position and the subsequent 1994 "Back to Sleep" campaign, the U.S. rate of sudden infant death syndrome (SIDS) has decreased more than 40%. This study reports sleep position practices in the greater Philadelphia area during 1996 and 1997. Four hundred and ten parents of infants 6 months of age or less answered a questionnaire by interview in Philadelphia clinics and private pediatric offices from December 1995 through February 1997. Sleep position practices and other SIDS risk factors were measured among demographic groups and compared with reported rates in a similar population from 1993 and 1994. Data were analyzed by Chi square after analysis of correlation coefficients. Significance is reported at p < 0.05. Seventy-two percent of all infants surveyed slept nonprone (NP) compared to 31.8% in 1993 and 59.1% in 1994. The population was 61% African-American (AA), 62% clinic patients. The breast feeding rate was 31%, maternal smoking 17%, and cosleeping 46%. AA infants (67% vs. 82%), infants receiving care at a clinic (66% vs. 84%), and infants > 3 months old (65% vs. 76%) are less likely to be placed nonprone. Most parents who place infants on their back report it was recommended by a medical professional (56%). The majority of those placing infants prone do so because their infant is more comfortable or sleeps better (65%), although 73% said their physician/nurse discussed sleep position with them. Nonprone sleeping continues to increase since the initiation of the "Back to Sleep" campaign. Disparity between some demographic groups persists. An excessive number of African-American families and clinic families still choose a prone sleep position. Many who do so cite increased infant comfort, despite knowledge of the AAP recommendation.

Behavioural sleep treatments and night time crying in infants: challenging the status quo.

PubMed

Blunden, Sarah L; Thompson, Kirrilly R; Dawson, Drew

2011-10-01

In Australia, as in many Westernised industrialised nations, the majority of families encourage infants to sleep alone or 'solo' from an early age. Sleeping solo can increase night time crying, which in turn disrupts sleep for both parent and infant. Night time waking and crying are frequently culturally constructed as behavioural sleep 'problems'. The pursuit of solo sleeping is thus achieved through 'behavioural sleep treatments' that teach an infant to sleep alone. Some behavioural extinction treatments necessitate a parent leaving an infant to cry for extended periods unattended, a practice reportedly difficult for parents. Despite parent's anxieties, and the potential (though little studied) stress to the infant, the pursuit of those behavioural sleep treatments are advocated by many psychologists and clinicians as acceptable and necessary interventions. This paper questions this necessity and critically reviews and debates these methods from biological, anthropological and cultural perspectives. Specifically, it considers Foucaultian, Leidloffian, attachment and behavioural perspectives. The central debate in this paper is if and why an infant's nocturnal cries should be ignored. It challenges the aetiology and acceptance of the status quo in the hope of revisiting the underlying belief that these methods are necessary. In doing so, the paper theorises the ways in which current sleep training techniques do or do not satisfy the needs of infants and their parents and questions the extent to which they can be reconciled. The paper posits an agenda for further research in the area that may facilitate the reconciliation of the needs of parents and those of their infants. Copyright © 2010 Elsevier Ltd.

Heart rate control in normal and aborted-SIDS infants.

PubMed

Pincus, S M; Cummins, T R; Haddad, G G

1993-03-01

Approximate entropy (ApEn), a mathematical formula quantifying regularity in data, was applied to heart rate data from normal and aborted-sudden infant death syndrome (SIDS) infants. We distinguished quiet from rapid-eye-movement (REM) sleep via the following three criteria, refining the notion of REM as more "variable": 1) REM sleep has greater overall variability (0.0374 +/- 0.0138 vs. 0.0205 +/- 0.0090 s, P < 0.005); 2) REM sleep is less stationary (StatAv = 0.742 +/- 0.110) than quiet sleep (StatAv = 0.599 +/- 0.159, P < 0.03); 3) after normalization to overall variability, REM sleep is more regular (ApEnsub = 1.224 +/- 0.092) than quiet sleep (ApEnsub = 1.448 +/- 0.071, P < 0.0001). Fifty percent of aborted-SIDS infants showed greater ApEn instability across quiet sleep than any normal infant exhibited, suggesting that autonomic regulation of heart rate occasionally becomes abnormal in a high-risk subject. There was an association between low ApEn values and aborted-SIDS events; 5 of 14 aborted-SIDS infants had at least one quiet sleep epoch with an ApEn value below the minimum of 45 normal-infant ApEn values.

The changing concept of sudden infant death syndrome: diagnostic coding shifts, controversies regarding the sleeping environment, and new variables to consider in reducing risk.

PubMed

2005-11-01

There has been a major decrease in the incidence of sudden infant death syndrome (SIDS) since the American Academy of Pediatrics (AAP) released its recommendation in 1992 that infants be placed down for sleep in a nonprone position. Although the SIDS rate continues to fall, some of the recent decrease of the last several years may be a result of coding shifts to other causes of unexpected infant deaths. Since the AAP published its last statement on SIDS in 2000, several issues have become relevant, including the significant risk of side sleeping position; the AAP no longer recognizes side sleeping as a reasonable alternative to fully supine sleeping. The AAP also stresses the need to avoid redundant soft bedding and soft objects in the infant's sleeping environment, the hazards of adults sleeping with an infant in the same bed, the SIDS risk reduction associated with having infants sleep in the same room as adults and with using pacifiers at the time of sleep, the importance of educating secondary caregivers and neonatology practitioners on the importance of "back to sleep," and strategies to reduce the incidence of positional plagiocephaly associated with supine positioning. This statement reviews the evidence associated with these and other SIDS-related issues and proposes new recommendations for further reducing SIDS risk.

2000-12-01

The purpose of this study was to evaluate the effects of a gentle human touch (GHT) intervention provided to 42 preterm infants (27-33 weeks gestational age), for 10 min, three times daily for 10 days. There was no significant difference in mean HR levels or in percent of abnormal heart rate (HR) or O2 saturation comparing 10-min baseline (B), GHT, and 10-min post-touch (PT) phases. There were significantly lower levels of active sleep, motor activity, and behavioral distress during GHT compared to B and P phases. There were no differences among the 42 infants in the GHT group and 42 infants in a randomly assigned control group on any outcome variable including weight gain, morbidity status, or behavioral organization. The findings suggest that GHT generally is a safe and soothing type of touch to provide to young preterm infants, but that individual infant responses to touch need to be continuously monitored by NICU staff and parents.

In the UK, infants of South Asian parents have a lower rate of sudden infant death syndrome (SIDS) than White British infants. Infant care and life style behaviours are strongly associated with SIDS risk. This paper describes and explores variability in infant care between White British and South Asian families (of Bangladeshi, Indian or Pakistani origin) in Bradford, UK (the vast majority of which were Pakistani) and identifies areas for targeted SIDS intervention. A cross-sectional telephone interview study was conducted involving 2560 families with 2- to 4-month-old singleton infants enrolled in the Born in Bradford cohort study. Outcome measures were prevalence of self-reported practices in infant sleeping environment, sharing sleep surfaces, breast feeding, use of dummy or pacifier, and life style behaviours. We found that, compared with White British infants, Pakistani infants were more likely to: sleep in an adult bed (OR = 8.48 [95% CI 2.92, 24.63]); be positioned on their side for sleep (OR = 4.42 [2.85, 6.86]); have a pillow in their sleep environment (OR = 9.85 [6.39, 15.19]); sleep under a duvet (OR = 3.24 [2.39, 4.40]); be swaddled for sleep (OR = 1.49 [1.13, 1.97]); ever bed-share (OR = 2.13 [1.59, 2.86]); regularly bed-share (OR = 3.57 [2.23, 5.72]); ever been breast-fed (OR = 2.00 [1.58, 2.53]); and breast-fed for 8+ weeks (OR = 1.65 [1.31, 2.07]). Additionally, Pakistani infants were less likely to: sleep in a room alone (OR = 0.05 [0.03, 0.09]); use feet-to-foot position (OR = 0.36 [0.26, 0.50]); sleep with a soft toy (OR = 0.52 [0.40, 0.68]); use an infant sleeping bag (OR = 0.20 [0.16, 0.26]); ever sofa-share (OR = 0.22 [0.15, 0.34]); be receiving solid foods (OR = 0.22 [0.17, 0.30]); or use a dummy at night (OR = 0.40 [0.33, 0.50]). Pakistani infants were also less likely to be exposed to maternal smoking (OR = 0.07 [0.04, 0.12]) and to alcohol consumption by either parent. No difference was found in the prevalence of prone sleeping (OR = 1.04 [0.53, 2.01]). Night-time infant care therefore differed significantly between South Asian and White British families. South Asian infant care practices were more likely to protect infants from the most important SIDS risks such as smoking, alcohol consumption, sofa-sharing and solitary sleep. These differences may explain the lower rate of SIDS in this population. © 2011 Blackwell Publishing Ltd.

Baby sleeping bag and conventional bedding conditions--comparative investigations by infrared thermography.

Thermal stress is a risk factor for sudden infant death syndrome (SIDS). Recently, baby sleeping bags have been recommended as a preventive measure against SIDS. The aim of this study was to describe in which way the use of baby sleeping bags might influence thermoregulation of sleeping infants and maybe the incidence of SIDS. Body surface temperature was recorded by use of infrared thermography in 15 infants (median age 49 days). Recordings were done twice: after sleeping for 60 min under a blanket and after sleeping for 60 min in a baby sleeping bag. Temperature was recorded and compared for defined sites of body surface. Infants' mean body surface temperature as well as core temperature after sleeping in a baby sleeping bag did not show significant differences when compared to infants sleeping under a conventional blanket. Under controlled conditions, core temperature and mean body surface temperature are comparable, equally if using a baby sleeping bag or conventional bedding. However, under the more uncontrolled conditions of baby care at home, sleeping bags might provide a more constant temperature profile, while other bedding conditions may lead to significant variations of temperature pattern. © Georg Thieme Verlag KG Stuttgart · New York.

Poehlmann, Julie

2009-01-01

Objective To test a transactional model of sleep–wake development in infants born preterm or low birthweight (PT LBW), which may inform clinical practice, interventions, and future research in this at risk population. Methods One hundred and twenty-eight mother–infant dyads participated from hospital discharge to 4 months postterm. Assessments of prematurity, infant sleep–wake patterns, maternal interaction quality, depression, feeding route, and sociodemographic factors were conducted. Results Path analyses revealed that maternal interactions directly related to infant sleep patterns and family sociodemographic risks related to less optimal parenting. In addition, bottle fed infants experienced fewer night wakings and more nighttime sleep. Conclusions Two potential pathways to sleep patterns in PT LBW infants were identified. The findings suggest directions for clinical work, such as supporting healthy infant sleep through parenting interventions or supporting interpersonal relations between parents and their PT LBW infants by encouraging more daytime naps. Additionally, clinicians should assess parents’ nighttime sleep concerns within the larger sociodemographic and feeding context. PMID:19098064

Long-term oscillations in the sleep/wake cycle of infants

2009-11-01

The development of circadian sleep-wakefulness rhythm was investigated by a longitudinal study of six normal infants. We propose an entropy based measure for the sleep/wake cycle fragmentation. Our results confirm that the sleep/wake cycle fragmentation and the sleep/wake ratio decrease, while the circadian power increases during the maturation process of infants. In addition to these expected linear trends in the variables devised to quantify sleep consolidation, circadian power and sleep/wake ratio, we found that they present infradian rhythms in the monthly range.

Cardio-respiratory control during sleep in infancy.

PubMed

Horne, Rosemary S C

2014-06-01

During the first year of life and particularly the first 6 months autonomic control of the cardio-respiratory system is still undergoing maturation and infants are at risk of cardio-respiratory instability. These instabilities are most marked during sleep, which is important as infants spend the majority of each 24 hours in sleep. Sleep state has a marked effect on the cardio-respiratory system with instabilities being more common in active sleep compared to quiet sleep. Responses to hypoxia are also immature during infancy and may make young infants more vulnerable to cardio-respiratory instability. It has been proposed that an inability to respond appropriately to a life threatening event underpins the Sudden Infant Death Syndrome (SIDS). The major risk factors for SIDS, prone sleeping and maternal smoking, both impair cardio-respiratory control in normal healthy term infants. Crown Copyright © 2013. Published by Elsevier Ltd.

2013-01-01

Accidental suffocation and strangulation in bed is a leading cause of preventable infant death. Bed sharing, teen motherhood, and Hispanic ethnicity have been associated with infant sleep suffocation death. Fifty-five Hispanic teen mothers were surveyed regarding acculturation/demographic characteristics and their infants' sleep behaviors. Most participants had 2 foreign-born parents from Latin America. Participants with 2 US-born parents were less likely to bed share than their less-acculturated peers. Many participants reported not always placing their infant in a supine sleep position. There is a significant need to reach out to Hispanic teen mothers, particularly from newer immigrant families, with culturally and linguistically appropriate multigenerational clinical messaging on the risks of infant bed sharing and nonsupine sleep positioning.

Tham, Elaine KH; Schneider, Nora; Broekman, Birit FP

2017-01-01

Objective Infant sleep development is a highly dynamic process occurring in parallel to and in interaction with cognitive and physical growth. This narrative review aims to summarize and discuss recent literature and provide an overview of the relation between infant sleep and cognitive development as well as physical growth. Methods We conducted online literature search using MEDLINE, Embase, and Cochrane Library databases. We considered original research on humans published in the English language from January 2005 to December 2015. Search terms included “sleep” AND “infant” AND “cognition” OR “memory” OR “executive functioning”, OR “growth” OR “obesity” OR “growth hormone” OR “stunting”, and combinations thereof. Results Ten studies on infant sleep and cognition were included in this review. Overall, findings indicated a positive association between sleep, memory, language, executive function, and overall cognitive development in typically developing infants and young children. An additional 20 studies support the positive role of infant sleep in physical growth, with the current literature focusing largely on weight gain and obesity rather than healthy growth. Existing evidence in both the domains is mainly based on cross-sectional designs, on association studies, and on parental reports. In contrast, there were limited studies on longitudinal sleep trajectories and intervention effects, or studies have not used more objective sleep measures such as actigraphy and polysomnography. Conclusion The reviewed studies support a critical and positive role of infant sleep in cognition and physical growth. Future studies should consider key environmental and parental confounders, include a combination of more objective (actigraphy) and subjective measures (sleep diaries and questionnaires), and move towards longitudinal trajectory designs of infant sleep and development.

2005-11-01

Infants sleeping in the prone position are at greater risk for sudden infant death syndrome (SIDS). Sleep position-dependent changes in cardiorespiratory activity may contribute to this increased risk. Cardiorespiratory activity is also affected by feeding. Twenty prematurely-born infants were studied at 31-36 weeks postconceptional age while sleeping in the prone and supine positions. Heart rate, respiratory rate, and patterns of variability were recorded during interfeed intervals, and effects of position and time after feeding were analyzed by repeated measures analyses of variance. There were significant effects of both sleeping position and time after feeding. Heart rate is higher and heart period variability is lower in the prone position, and the effects of sleeping position on cardiac functioning are more pronounced during the middle of the intrafeed interval. In preterm infants, autonomic responses to nutrient processing modulate the cardiorespiratory effects of sleeping position. Prone sleeping risk may vary with time after feeding.

Association between sleep position and early motor development.

To compare motor performance in infants sleeping in prone versus supine positions. Healthy 4-month-olds (supine: n = 71, prone: n = 12) and 6-month olds (supine: n = 50, prone: n = 22) were evaluated with the Alberta Infant Motor Scale (AIMS) and Peabody Developmental Motor Scale (PDMS), and parents completed a positioning diary. Infants were reassessed at 15 months. At 4 months, motor scores were lower in the supine group and were less likely to achieve prone extension (P < .05). At 6 months, there were wide discrepancies on the AIMS (supine: 44.5 +/- 21.6, prone: 60.0 +/- 18.8, P = .005) and the gross motor PDMS (supine: 85.7 +/- 7.6, prone: 90.2 +/- 9.5, P = .03). Motor delays were documented in 22% of babies sleeping supine. Prone sleep-positioned infants were more likely to sit and roll. Daily exposure to awake prone positioning was predictive of motor performance in infants sleeping supine. At 15 months, sleep position continued to predict motor performance. Infants sleeping supine may exhibit early motor lags, associated with less time in prone while awake. This has implications for accurate interpretation of assessment of infants at risk and prevention of inappropriate referrals. Rate of infant motor development appears influenced by extrinsic factors such as positioning practices.

Breathing patterns are characteristically different between infant active sleep (AS) and quiet sleep (QS), and statistical quantifications of interbreath interval (IBI) data have previously been used to discriminate between infant sleep states. It has also been identified that breathing patterns are governed by a nonlinear controller. This study aims to investigate whether nonlinear quantifications of infant IBI data are characteristically different between AS and QS, and whether they may be used to discriminate between these infant sleep states. Polysomnograms were obtained from 24 healthy infants at six months of age. Periods of AS and QS were identified, and IBI data extracted. Recurrence quantification analysis (RQA) was applied to each period, and recurrence calculated for a fixed radius in the range of 0-8 in steps of 0.02, and embedding dimensions of 4, 6, 8, and 16. When a threshold classifier was trained, the RQA variable recurrence was able to correctly classify 94.3% of periods in a test dataset. It was concluded that RQA of IBI data is able to accurately discriminate between infant sleep states. This is a promising step toward development of a minimal-channel automatic sleep state classification system.

Objectives. With a focus on socioeconomic position, we examined the association between maternal education and nonsupine infant sleep position, and examined patterns of effect modification with additional sociodemographic, maternal, infant, and health services predictors. Methods. Data were from the Maternity Experiences Survey, a national population-based sample of 76 178 new Canadian mothers (unweighted n = 6421) aged 15 years or older interviewed in 2006–2007. Using logistic regression, we developed multivariate models for 3 maternal education strata. Results. Level of maternal education was significantly and inversely related to nonsupine infant sleep position. Stratified analyses revealed different predictive factors for nonsupine infant sleep position across strata of maternal education. Postpartum home visits were not associated with use of this sleep position among new mothers with less than high school completion. Adequacy of postpartum information regarding sudden infant death syndrome was not associated with nonsupine infant sleep position in any of the educational strata. Conclusions. These findings suggest a need to revisit Back to Sleep health promotion strategies and to ensure that these interventions are tailored to match the information needs of all families, including mothers with lower levels of formal education.

Reduction of prone infant sleep position has been the main public health effort to reduce the incidence of Sudden Infant Death Syndrome (SIDS). Oregon Pregnancy Risk Assessment Monitoring System (PRAMS) surveys a stratified random sample of women after a live birth. In 1998-1999, 1867 women completed the survey (64.0% unweighted response; 73.5% weighted response). Overall, 9.2% of all women "usually" chose prone infant sleep position, while 24.2% chose side and 66.5% chose supine position. Women receiving care from private physicians or HMOs more often chose prone position (10.6%) than women receiving prenatal care from health department clinics (2.5%), hospital clinics (6.1%) or other sites (8.3%). Compared to health department prenatal clinic patients, private prenatal patients were more likely to choose prone infant sleep position, adjusted odds ratio = 4.78 (95% confidence interval [CI] 1.64-13.92). Health Department clinics have done a better job than private physicians in educating mothers about putting infants to sleep on their backs. Providers-especially private providers-should continue to stress the importance of supine sleep position for infants.

Baby Business: a randomised controlled trial of a universal parenting program that aims to prevent early infant sleep and cry problems and associated parental depression

PubMed Central

2012-01-01

Background Infant crying and sleep problems (e.g. frequent night waking, difficulties settling to sleep) each affect up to 30% of infants and often co-exist. They are costly to manage and associated with adverse outcomes including postnatal depression symptoms, early weaning from breast milk, and later child behaviour problems. Preventing such problems could improve these adverse outcomes and reduce costs to families and the health care system. Anticipatory guidance-i.e. providing parents with information about normal infant sleep and cry patterns, ways to encourage self-settling in infants, and ways to develop feeding and settling routines before the onset of problems-could prevent such problems. This paper outlines the protocol for our study which aims to test an anticipatory guidance approach. Methods/Design 750 families from four Local Government Areas in Melbourne, Australia have been randomised to receive the Baby Business program (intervention group) or usual care (control group) offered by health services. The Baby Business program provides parents with information about infant sleep and crying via a DVD and booklet (mailed soon after birth), telephone consultation (at infant age 6-8 weeks) and parent group session (at infant age 12 weeks). All English speaking parents of healthy newborn infants born at > 32 weeks gestation and referred by their maternal and child health nurse at their first post partum home visit (day 7-10 postpartum), are eligible. The primary outcome is parent report of infant night time sleep as a problem at four months of age and secondary outcomes include parent report of infant daytime sleep or crying as a problem, mean duration of infant sleep and crying/24 hours, parental depression symptoms, parent sleep quality and quantity and health service use. Data will be collected at two weeks (baseline), four months and six months of age. An economic evaluation using a cost-consequences approach will, from a societal perspective, compare costs and health outcomes between the intervention and control groups. Discussion To our knowledge this is the first randomised controlled trial of a program which aims to prevent both infant sleeping and crying problems and associated postnatal depression symptoms. If effective, it could offer an important public health prevention approach to these common, distressing problems. Trial registration number ISRCTN: ISRCTN63834603 PMID:22309617

2018-01-01

Establishment of a consistent bedtime routine is often recommended to families with young children with sleep difficulties. However, there are limited studies assessing specific bedtime routines in the treatment of infant and toddler sleep disturbances. Thus, the purpose of this study was to examine the impact of a massage-based bedtime routine on infant sleep, maternal sleep, and maternal mood. A total of 123 mothers and their 3- to 18-month-old infant were randomly assigned to a routine (one-week baseline of usual bedtime routine, two-weeks intervention) or control group (three-weeks of their usual bedtime routine). All mothers completed the Brief Infant Sleep Questionnaire (BISQ) on a weekly basis and measures of maternal sleep and mood (eg, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and Edinburgh Postnatal Depression Scale). This bedtime routine resulted in improvements in child and mother night wakings, maternal perceptions of child sleep and mood (ie, sleep problem, bedtime ease, and morning mood), and improvements in maternal sleep quality. No comparative changes were seen in the control group. Notably, other than number of night wakings for both the child and the mother, there were no changes in other sleep patterns including sleep onset latency, duration of night wakings, longest stretch of sleep, or sleep duration. This study supports recommending a massage-based routine in those families, with the codicil that improvements in maternal perceptions and maternal sleep will be noted, with few improvements in sleep itself other than night wakings.

On the basis of the circadian nutritional variations present in breast milk, and of the implications for the sleep/wake cycle of the nutrients present in infant formula milks, we designed a formula milk nutritionally dissociated into a Day/Night composition. The goal was to improve the bottle-fed infant's sleep/wake circadian rhythm. A total of 21 infants aged 4-20 weeks with sleeping difficulties were enrolled in the three-week duration study. The sleep analysis was performed using an actimeter (Actiwatch) placed on an ankle of each infant to uninterruptedly record movements during the three weeks. The dissociated Day milk, designed to be administered from 06:00 to 18:00, contained low levels of tryptophan (1.5g/100g protein) and carbohydrates, high levels of proteins, and the nucleotides Cytidine 5 monophosphate, Guanosine 5 monophosphate and Inosine 5 monophosphate. The dissociated Night milk, designed to be administered from 18.00 to 06.00, contained high levels of tryptophan (3.4g/100g protein) and carbohydrates, low levels of protein, and the nucleotides Adenosine 5 monophosphate and Uridine 5 monophosphate. Three different milk-feeding experiments were performed in a double-blind procedure covering three weeks. In week 1 (control), the infants received both by day and by night a standard formula milk; in week 2 (inverse control), they received the dissociated milk inversely (Night/Day instead of Day/Night); and in week 3, they received the Day/Night dissociated formula concordant with the formula design. When the infants were receiving the Day/Night dissociated milk in concordance with their environment, they showed improvement in all the nocturnal sleep parameters analyzed: total hours of sleep, sleep efficiency, minutes of nocturnal immobility, nocturnal awakenings, and sleep latency. In conclusion, the use of a chronobiologically adjusted infant formula milk seems to be effective in improving the consolidation of the circadian sleep/wake cycle in bottle-fed infants.

To examine the relationship between unsettled infant behaviour and fathers' depressive symptoms, cognitions surrounding infant sleep (anger, doubt), and personal sleep, in a community cohort. Data were collected from 102 fathers of healthy infants at 4 weeks, 4 months and 6 months of age. Measures included father report of infant sleep and crying problems, depressive symptoms, cognitions about infant sleep and own sleep quality and quantity. Data were analysed using adjusted regression models. Sleep problems at 4 months of age were associated with increased depressive symptoms (adjusted mean difference 2.64 (1.27-4.00)), doubt (adjusted mean difference 1.82 (0.40-3.25)), anger (adjusted mean difference 1.86 (0.51-3.20)), poor personal sleep quantity (adjusted odds ratio (OR) 0.21; 95% confidence interval (CI) 0.09-0.51) and quality (adjusted OR 0.20; 95% CI 0.08-0.51); and at 6 months of age, with increased depressive symptoms (adjusted mean difference 2.56 (1.28-3.84)), anger (adjusted mean difference 1.63 (0.40-2.87)), poor personal sleep quantity (adjusted OR 0.14; 95% CI 0.05-0.38) and quality (adjusted OR 0.28; 95% CI 0.11-0.72). Infant cry problems at 4 months were associated with increased anger (adjusted mean difference 1.98 (0.60-3.36)) and doubt (adjusted mean difference 1.55 (0.05-3.05)); and at 6 months, with increased depressive symptoms (adjusted mean difference 3.04 (1.59-4.69)), anger (adjusted mean difference 2.73 (1.29-4.17)) and less personal sleep (adjusted OR 0.22; 95% CI 0.07-0.71). Fathers of unsettled infants reported greater anger towards their infant and increased depressive symptoms by 4 months infant age, with these symptoms persisting 2 months later. Evidence-based interventions are needed for these fathers. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

The supine sleeping position with the head higher than the legs has no impact on regurgitations in infants. Inclined ventral decubitus decreases regurgitations but is associated with an increased risk of sudden infant death syndrome (SIDS). The LUNE study aimed to evaluate the impact of regurgitations on the choice of sleeping position by pediatricians and parents. Cross-sectional case-control study (ratio 1:1) conducted in France in 2013. A representative sample of pediatricians recruited 3-week to 4-month-old breast- or formula-fed infants. Cases and controls were defined by the presence or absence of regurgitations. Collected data included Vandenplas codification for regurgitations (VD, range 0-6), associated symptoms, and variations in sleeping position since maternity hospital discharge. A total of 1347 cases and 1346 controls were recruited by 493 pediatricians. Regurgitations were evaluated at VD1 (minor, 22 % of cases), VD2 (mild, 47 % of cases), or VD≥3 (moderate to severe, 31 % of cases). At the maternity hospital, the supine position was recommended to 96 % of parents for SIDS prevention. Since discharge, parents asked questions about the relationship between sleeping position and regurgitations (79 % of infants with GER versus 45 % of controls). The sleeping position was modified at least once since maternity discharge (42 % of infants with GER versus 35 % of controls). At inclusion, 86 % of infants with GER and 86 % of controls were sleeping on their back. Fifty-one percent of infants with GER and 28 % of controls slept in an inclined position. Pediatricians repeated the prescription of dorsal decubitus for 91 % of infants with GER and recommended an inclined position in 70 %. Regurgitations had no impact on supine sleeping position. The inclined supine sleeping position was more frequent in infants with regurgitations with pediatricians' assent, which is not in agreement with evidence-based medicine.

African-American and Hispanic families share similar socioeconomic profiles. Hispanic rates of sleep-related infant death are four times lower than African-American rates. We conducted a cross-sectional, multi-modal (surveys, qualitative interviews) study to compare infant care practices that impact risk for sleep-related infant death in African-American and Hispanic families. We surveyed 422 African-American and 90 Hispanic mothers. Eighty-three African-American and six Hispanic mothers participated in qualitative interviews. African-American infants were more likely to be placed prone (p < 0.001), share the bed with the parent (p < 0.001), and to be exposed to smoke (p < 0.001). Hispanic women were more likely to breastfeed (p < .001), while African-American women were more knowledgeable about SIDS. Qualitative interviews indicate that, although African-American and Hispanic parents had similar concerns, behaviors differed. Although the rationale for infant care decisions was similar for African-American and Hispanic families, practices differed. This may help to explain the racial/ethnic disparity seen in sleep-related infant deaths.

The purpose of this study was to determine the effects of body position (prone, supine and lateral) together with sleep status (wake and sleep) on the cardiorespiratory stability of near-term infants. A total of 53 infants (gestational age at birth 33.2 ± 3.5 weeks; birth weight 1,682 ± 521 g; gestational age at recording 38.6 ± 2.1 weeks; weight at recording: 2,273 ± 393 g) were monitored for 24 hours for clinically significant apnea (>15 seconds), bradycardia (<100 bpm), and oxygen desaturation (SpO 2  < 90%) in alternating body positions (prone, supine and lateral) by cardiorespiratory monitors and 3-orthogonal-axis accelerometers. Sleep status of the infants was also continuously monitored by actigraphs. No apnea was observed. During wake, severe bradycardia was most frequently observed in the lateral position while, during sleep, severe bradycardia was most frequently observed in the supine position. Desaturation was most frequently observed in the supine and lateral positions during both wake and sleep. Our study suggests that the cardiorespiratory stability of infants is significantly compromised by both body position and sleep status. During both wake and sleep, prone position induces the most stable cardiorespiratory functions of near-term infants.

OBJECTIVE: Sudden infant death syndrome and other sleep-related causes of infant mortality have several known risk factors. Less is known about the association of those risk factors at different times during infancy. Our objective was to determine any associations between risk factors for sleep-related deaths at different ages. METHODS: A cross-sectional study of sleep-related infant deaths from 24 states during 2004–2012 contained in the National Center for the Review and Prevention of Child Deaths Case Reporting System, a database of death reports from state child death review teams. The main exposure was age, divided into younger (0–3 months) and older (4 months to 364 days) infants. The primary outcomes were bed-sharing, objects in the sleep environment, location (eg, adult bed), and position (eg, prone). RESULTS: A total of 8207 deaths were analyzed. Younger victims were more likely bed-sharing (73.8% vs 58.9%, P < .001) and sleeping in an adult bed/on a person (51.6% vs 43.8%, P < .001). A higher percentage of older victims had an object in the sleep environment (39.4% vs 33.5%, P < .001) and changed position from side/back to prone (18.4% vs 13.8%, P < .001). Multivariable regression confirmed these associations. CONCLUSIONS: Risk factors for sleep-related infant deaths may be different for different age groups. The predominant risk factor for younger infants is bed-sharing, whereas rolling into objects in the sleep area is the predominant risk factor for older infants. Parents should be warned about the dangers of these specific risk factors appropriate to their infant’s age. PMID:25022735

Arousal from sleep mechanisms in infants.

PubMed

Franco, Patricia; Kato, Ineko; Richardson, Heidi L; Yang, Joel S C; Montemitro, Enza; Horne, Rosemary S C

2010-08-01

Arousals from sleep allow sleep to continue in the face of stimuli that normally elicit responses during wakefulness and also permit awakening. Such an adaptive mechanism implies that any malfunction may have clinical importance. Inadequate control of arousal in infants and children is associated with a variety of sleep-related problems. An excessive propensity to arouse from sleep favors the development of repeated sleep disruptions and insomnia, with impairment of daytime alertness and performance. A lack of an adequate arousal response to a noxious nocturnal stimulus reduces an infant's chances of autoresuscitation, and thus survival, increasing the risk for Sudden Infant Death Syndrome (SIDS). The study of arousability is complicated by many factors including the definition of an arousal; the scoring methodology; the techniques used (spontaneous arousability versus arousal responses to endogenous or exogenous stimuli); and the confounding factors that complicate the determination of arousal thresholds by changing the sleeper's responses to a given stimulus such as prenatal drug, alcohol, or cigarette use. Infant age and previous sleep deprivation also modify thresholds. Other confounding factors include time of night, sleep stages, the sleeper's body position, and sleeping conditions. In this paper, we will review these different aspects for the study of arousals in infants and also report the importance of these studies for the understanding of the pathophysiology of some clinical conditions, particularly SIDS.

Background There is some evidence that sleep patterns may be affected by iron deficiency anemia but the role of iron in sleep has not been tested in a randomized iron supplementation trial. Objective We investigated the effect of iron supplementation on maternal reports of sleep in infants in 2 randomized, placebo-controlled trials from Pemba Island, Zanzibar, and Nepal. Design In both studies, which had parallel designs and were carried out in years 2002 to 2003, infants received iron–folic acid with or without zinc daily for 12 months, and assessments of development were made every 3 months for the duration of the study. Eight hundred seventy-seven Pemban (12.5 ± 4.0 months old) and 567 Nepali (10.8 ± 4.0 months) infants participated. Maternal reports of sleep patterns (napping frequency and duration, nighttime sleep duration, frequency of night waking) were collected. Results Mean Hb concentration was 9.2 ± 1.1 for Pemban and 10.1 ± 1.2 g/dL for Nepali infants. Approximately, one-third of the children were stunted. Supplemental iron was consistently associated with longer night and total sleep duration. The effects of zinc supplementation also included longer sleep duration. Conclusions Micronutrient supplementation in infants at high risk for iron deficiency and iron deficiency anemia was related to increased night sleep duration and less night waking. PMID:19322104

Traditional screen time (e.g. TV and videogaming) has been linked to sleep problems and poorer developmental outcomes in children. With the advent of portable touchscreen devices, this association may be extending down in age to disrupt the sleep of infants and toddlers, an age when sleep is essential for cognitive development. However, this association has not been demonstrated empirically. This study aims to examine whether frequency of touchscreen use is associated with sleep in infants and toddlers between 6 and 36 months of age. An online survey was administered to 715 parents reporting on child media use (daily exposure to TV and use of touchscreens), sleep patterns (night-time and daytime sleep duration, sleep onset - time to fall asleep, and frequencies of night awakenings). Structural equation models controlling for age, sex, TV exposure and maternal education indicated a significant association between touchscreen use and night-time sleep, daytime sleep and sleep onset. No significant effect was observed for the number of night awakenings. To our knowledge, this is the first report linking the use of touchscreen with sleep problems in infants and toddlers. Future longitudinal studies are needed to clarify the direction of effects and the mechanisms underlying these associations using detailed sleep tracking. PMID:28406474

To examine the prevalence and correlates of nighttime awakenings and to explore the association between sleep and cognitive development in a community sample of infants and toddlers. A total of 590 healthy infants (aged 2-11 months) and 512 toddlers (aged 12-30 months) from 8 provinces of China were assessed for their sleep and cognitive development. Data on sleep duration and nighttime awakenings were collected through the Brief Infant Sleep Questionnaire. Cognitive development was assessed by trained pediatricians using the Bayley Scales of Infant Development. Prevalence of no nighttime awakening, and nighttime awakening(s) for 1×/night, 2×/night, and ≥ 3×/night was 6.8%, 20.2%, 33.2%, and 39.3% in infants, and was 25.8%, 34.6%, 23.8%, and 15.8% in toddlers, respectively. Nighttime awakenings were generally associated with younger age, lower maternal education level, and being currently breastfed. In addition, nighttime awakenings were associated with being boys in toddlers. After controlling for potential confounders, infants with nighttime awakenings for 2×/night were found to have significantly higher Mental Development Index (MDI) score, as compared to those without and those with more frequent nighttime awakenings. However, toddlers with nighttime awakenings for ≥ 3×/night had significantly lower MDI, as compared to those with fewer nighttime awakenings. Total sleep duration was not associated with any developmental indices in both infants and toddlers. Frequent nighttime awakenings are associated with poor cognitive functions in toddlers. Meanwhile, a nonlinear association between nighttime awakenings and cognitive performance was found among infants. The findings provide a developmental context for the effect of sleep on cognitive abilities in young children. Further longitudinal studies and interventional studies on the effects of parent-based sleep-focused intervention on cognitive abilities among young children are warranted. © 2018 American Academy of Sleep Medicine.

Sofas and Infant Mortality

PubMed Central

Rechtman, Lauren R.; Colvin, Jeffrey D.; Blair, Peter S.

2014-01-01

OBJECTIVE: Sleeping on sofas increases the risk of sudden infant death syndrome and other sleep-related deaths. We sought to describe factors associated with infant deaths on sofas. METHODS: We analyzed data for infant deaths on sofas from 24 states in 2004 to 2012 in the National Center for the Review and Prevention of Child Deaths Case Reporting System database. Demographic and environmental data for deaths on sofas were compared with data for sleep-related infant deaths in other locations, using bivariate and multivariable, multinomial logistic regression analyses. RESULTS: A total of 1024 deaths on sofas made up 12.9% of sleep-related infant deaths. They were more likely than deaths in other locations to be classified as accidental suffocation or strangulation (adjusted odds ratio [aOR] 1.9; 95% confidence interval [CI], 1.6–2.3) or ill-defined cause of death (aOR 1.2; 95% CI, 1.0–1.5). Infants who died on sofas were less likely to be Hispanic (aOR 0.7; 95% CI, 0.6–0.9) compared with non-Hispanic white infants or to have objects in the environment (aOR 0.6; 95% CI, 0.5–0.7) and more likely to be sharing the surface with another person (aOR 2.4; 95% CI, 1.9–3.0), to be found on the side (aOR 1.9; 95% CI, 1.4–2.4), to be found in a new sleep location (aOR 6.5; 95% CI, 5.2–8.2), and to have had prenatal smoke exposure (aOR 1.4; 95% CI, 1.2–1.6). Data on recent parental alcohol and drug consumption were not available. CONCLUSIONS: The sofa is an extremely hazardous sleep surface for infants. Deaths on sofas are associated with surface sharing, being found on the side, changing sleep location, and experiencing prenatal tobacco exposure, which are all risk factors for sudden infant death syndrome and sleep-related deaths.

Maternal depression has been associated with excessive infant crying, feeding and sleeping problems, but the specificity of maternal depression, as compared with maternal anxiety remains unclear and manifest disorders prior to pregnancy have been widely neglected. In this prospective longitudinal study, the specific associations of maternal anxiety and depressive disorders prior to, during and after pregnancy and infants' crying, feeding and sleeping problems were investigated in the context of maternal parity. In the Maternal Anxiety in Relation to Infant Development (MARI) Study, n = 306 primiparous and multiparous women were repeatedly interviewed from early pregnancy until 16 months post partum with the Composite International Diagnostic Interview for Women (CIDI-V) to assess DSM-IV anxiety and depressive disorders. Information on excessive infant crying, feeding and sleeping problems was obtained from n = 286 mothers during postpartum period via questionnaire and interview (Baby-DIPS). Findings from this study revealed syndrome-specific risk constellations for maternal anxiety and depressive disorders as early as prior to pregnancy: Excessive infant crying (10.1%) was specifically associated with maternal anxiety disorders, especially in infants of younger and lower educated first-time mothers. Feeding problems (36.4%) were predicted by maternal anxiety (and comorbid depressive) disorders in primiparous mothers and infants with lower birth weight. Infant sleeping problems (12.2%) were related to maternal depressive (and comorbid anxiety) disorders irrespective of maternal parity. Primiparous mothers with anxiety disorders may be more prone to anxious misinterpretations of crying and feeding situations leading to an escalation of mother-infant interactions. The relation between maternal depressive and infant sleeping problems may be better explained by a transmission of unsettled maternal sleep to the fetus during pregnancy or a lack of daily structure and bedtime routine with the infant. Maternal disorders prior to pregnancy require more attention in research and clinical practice. © 2015 John Wiley & Sons Ltd.

Infants show robust ability to track transitional probabilities within language and can use this information to extract words from continuous speech. The degree to which infants remember these words across a delay is unknown. Given well-established benefits of sleep on long-term memory retention in adults, we examine whether sleep similarly facilitates memory in 6.5month olds. Infants listened to an artificial language for 7minutes, followed by a period of sleep or wakefulness. After a time-matched delay for sleep and wakefulness dyads, we measured retention using the head-turn-preference procedure. Infants who slept retained memory for the extracted words that was prone to interference during the test. Infants who remained awake showed no retention. Within the nap group, retention correlated with three electrophysiological measures (1) absolute theta across the brain, (2) absolute alpha across the brain, and (3) greater fronto-central slow wave activity (SWA).

Purpose The aim of this study was to determine if massage therapy can be used as an adjunct intervention to induce sleep in infants born preterm. Methods Thirty infants born at a minimum of 28 weeks gestational age (GA), who were at the time of the study between 32-48 weeks adjusted GA, were randomly assigned to receive massage therapy on 1 day and not receive massage on an alternate day. The Motionlogger® Micro Sleep Watch® Actigraph recorded lower extremity activity on the morning of each day. Results No significant difference was found between groups for sleep efficiency (P=.13) for the time period evaluated. Groups differed significantly during the time period after the massage ended with more infants sleeping on the non-massage day (Χ2= 4.9802, P=.026). Conclusions Massage is well tolerated in infants born preterm and infants do not fall asleep faster after massage than without massage. PMID:25251794

The Interface Among Poverty, Air Mattress Industry Trends, Policy, and Infant Safety.

Doering, Jennifer J; Salm Ward, Trina C

2017-06-01

Infants can suffocate on air mattresses, even when the mattress is fully inflated. The interfacing issues of poverty, the bedbug epidemic, and changes in the design and marketing of air mattresses may be increasing consumer use of air mattresses as primary sleep environments and thus increasing the potential for infant death. Despite recent changes to improve air mattress safety labeling, the National Child Death Review Case Reporting System found that between 2004 and 2015 across 24 states, an air mattress was the incident sleep place for 108 infants whose deaths were either during sleep or in a sleep environment. At the same time, design components such as inflatable headboards and memory foam pillow tops potentially increase the hazard to infants, and marketing changes represent air mattresses as a preferred low-cost primary sleep environment. Analysis of current data surveillance systems, published position statements, and consumer materials from national organizations and federal agencies reveal opportunities for changing policy to better protect infants from this hazard.

Though the Back to Sleep Campaign that began in 1994 caused an overall decrease in sudden infant death syndrome (SIDS) rates, racial disparity has continued to increase in St. Louis. Though researchers have analyzed and described various sociodemographic characteristics of SIDS and infant deaths by unintentional suffocation in St. Louis, they have not simultaneously controlled for contributory risk factors to racial disparity such as race, poverty, maternal education, and number of children born to each mother (parity). To determine whether there is a relationship between maternal socioeconomic factors and sleep-related infant death. This quantitative case-control study used secondary data collected by the Missouri Department of Health and Senior Services between 2005 and 2009. The sample includes matched birth/death certificates and living birth certificates of infants who were born/died within time frame. Descriptive analysis, Chi-square, and logistic regression. The controls were birth records of infants who lived more than 1 year. Chi-square and logistic regression analyses confirmed that race and poverty have significant relationships with infant sleep-related deaths. The social significance of this study is that the results may lead to population-specific modifications of prevention messages that will reduce infant sleep-related deaths. © 2013 Wiley Periodicals, Inc.

"My child has a sleep problem": a cross-cultural comparison of parental definitions.

Sleep problems are highly prevalent in early childhood. In many cases, parents seek professional help when they suspect their child suffers from a sleep problem. The aim of this study was to explore sleep, demographic and cultural factors associated with parental definition of child sleep problem in a large-scale, cross cultural study. Parents (or caregivers) of 29,287 infants and toddlers (aged 0-3 years) from 17 countries completed a questionnaire on their child's sleep patterns, sleep setting, and demographic variables. The results indicated that, in comparison to parents from predominantly Caucasian (PC) countries, parents from predominantly Asian (PA) countries were significantly more likely to identify a sleep problem in their children (26% vs 52% overall; 2% vs 17% "severe" sleep problem). Furthermore, whereas infant sleep variables were strong predictors of a sleep problem definition in PC countries, they were significantly less predictive in PA countries where demographic variables played a significant role. These results highlight the need to further explore the role of demographic and cultural variables in determining parental perception of a sleep problem, a perception that relates to help seeking professional treatment for infant sleep problems. Our findings also emphasize the need to educate parents about infant and toddler sleep and to provide parents information and screening tools to help them identify sleep problems in a more evidence-based approach.

Why babies should never sleep alone: a review of the co-sleeping controversy in relation to SIDS, bedsharing and breast feeding.

PubMed

McKenna, James J; McDade, Thomas

2005-06-01

There has been much controversy over whether infants should co-sleep or bedshare with an adult caregiver and over whether such practises increase the risk of SIDS or fatal accident. However, despite opposition from medical authorities or the police, many western parents are increasingly adopting night-time infant caregiving patterns that include some co-sleeping, especially by those mothers who choose to breast feed. This review will show that the relationships between infant sleep patterns, infant sleeping arrangements and development both in the short and long term, whether having positive or negative outcomes, is anything but simple and the traditional habit of labelling one sleeping arrangement as being superior to another without an awareness of family, social and ethnic context is not only wrong but possibly harmful. We will show that there are many good reasons to insist that the definitions of different types of co-sleeping and bedsharing be recognised and distinguished. We will examine the conceptual issues related to the biological functions of mother-infant co-sleeping, bedsharing and what relationship each has to SIDS. At very least, we hope that the studies and data described in this paper, which show that co-sleeping at least in the form of roomsharing especially with an actively breast feeding mother saves lives, is a powerful reason why the simplistic, scientifically inaccurate and misleading statement 'never sleep with your baby' needs to be rescinded, wherever and whenever it is published.

The Neonatal Individualized Developmental Care Program (NIDCAP) for very low birth weight (VLBW) preterm infants has been suggested by Als et al to improve several medical outcome variables such as time on ventilator, time to nipple feed, the duration of hospital stay, better behavioral performance on Assessment of Preterm Infants' Behavior (APIB), and improved neurodevelopmental outcomes. We have tested the hypothesis of whether the infants who had received NIDCAP would show advanced sleep-wake pattern, behavioral, and neurodevelopmental outcome. Thirty-five VLBW infants were randomly assigned to receive NIDCAP or routine infant care. The goals for NIDCAP intervention were to enhance comfort and stability and to reduce stress and agitation for the preterm infants by: a) altering the environment by decreasing excess light and noise in the neonatal intensive care unit (NICU) and by using covers over the incubators and cribs; b) use of positioning aids such as boundary supports, nests, and buntings to promote a balance of flexion and extension postures; c) modification of direct hands-on caregiving to maximize preparation of infants for, tolerance of, and facilitation of recovery from interventions; d) promotion of self-regulatory behaviors such as holding on, grasping, and sucking; e) attention to the readiness for and the ability to take oral feedings; and f) involving parents in the care of their infants as much as possible. The infants' sleep was recorded at 36 weeks postconceptional age (PCA) and at 3 months corrected age (CA) using the Motility Monitoring System (MMS), an automated, nonintrusive procedure for determining sleep state from movement and respiration patterns. Behavioral and developmental outcome was assessed by the Neurobehavioral Assessment of the Preterm Infant (NAPI) at 36 weeks PCA, the APIB at 42 weeks PCA, and by the Bayley Scales of Infant Development (BSID) at 4, 12, and 24 months CA. Sleep developmental measures at 3 months CA showed a clear developmental change compared with 36 weeks PCA. These include: increased amount of quiet sleep, reduced active sleep and indeterminate sleep, decreased arousal, and transitions during sleep. Longest sleep period at night showed a clear developmental effect (increased) when comparing nighttime sleep pattern of infants at 3 months with those at 36 weeks of age. Day-night rhythm of sleep-wake increased significantly from 36 weeks PCA to 3 months CA. However, neither of these sleep developmental changes showed any significant effects of NIDCAP intervention. Although all APIB measures showed better organized behavior in NIDCAP patients, neither NAPI nor Bayley showed any developmental advantages for the intervention group. The neurodevelopmental outcome measured by the Bayley at 4, 12, and 24 months CA showed 64% of the NIDCAP intervention group at the lowest possible score compared with 33% of the control group. These findings could not be explained by the occurrence of intraventricular hemorrhage or the socioeconomic status of the parents, which showed no significant group effect. The results of this study, including measures of sleep maturation and neurodevelopmental outcome up to 2 years of age did not demonstrate that the NIDCAP intervention results in increased maturity or development. Buehler et al (Pediatrics. 1995;96:923-932) have reported that premature infants (N = 12; mean gestational age 32 weeks, mean birth weight 1700 g) who received developmental care compared with a similar group of infants who received routine care showed better organized behavioral performance on an APIB assessment at 42 weeks PCA. None of the medical outcome measures were significantly different in this study. Although our APIB results are in agreement, the results of the NAPI, the Bayley and sleep measures do not show an increase in neurodevelopmental maturation.

Randomized controlled trials of treatment for deformational plagiocephaly and brachycephaly have been lacking in the literature. Infants (n = 126) presenting to a plagiocephaly clinic were randomized to either positioning strategies or to positioning plus the use of a Safe T Sleep™ positioning wrap. Head shape was measured using a digital photographic technique, and neck function was assessed. They were followed up at home 3, 6 and 12 months later. There was no difference in head shape outcomes for the two treatment groups after 12 months of follow-up, with 42% of infants having head shapes in the normal range by that time. Eighty per cent of children showed good improvement. Those that had poor improvement were more likely to have both plagiocephaly and brachycephaly and to have presented later to clinic. Most infants improved over the 12-month study period, although the use of a sleep positioning wrap did not increase the rate of improvement. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.

Delivery of inhaled medications to infants is usually very demanding and is often associated with crying and mask rejection. It has been suggested that aerosol administration during sleep may be an attractive alternative. Previous studies in sleeping children were disappointing as most of the children awoke and rejected the treatment. The SootherMask (SM) is a new, gentle and innovative approach for delivering inhaled medication to infants and toddlers. The present pilot study describes the feasibility of administering inhaled medications during sleep using the SM. Prospective observational study. Out patients. 13 sleeping infants with recurrent wheezing who regularly used pacifiers and were <12 months old. Participants inhaled technetium99mDTPA-labelled normal saline aerosol delivered via a Respimat Soft Mist Inhaler (SMI) (Boehringer-Ingelheim, Germany) and SM + InspiraChamber (IC; InspiRx Inc, New Jersey, USA). The two major outcomes were the acceptability of the treatment and the lung deposition (per cent of emitted dose). All infants who fulfilled the inclusion criteria successfully received the SM treatment during sleep without difficulty. Mean lung deposition (±SD) averaged 1.6±0.5% in the right lung. This study demonstrated that the combination of Respimat, IC and SM was able to administer aerosol therapy to all the sleeping infants who were regular pacifier users with good lung deposition. Administration of aerosols during sleep is advantageous since all the sleeping children accepted the mask and ensuing aerosol therapy under these conditions, in contrast to previous studies in which there was frequent mask rejection using currently available devices.

The incidence of infant allergic diseases have increased recently, and it may be caused by multiple influences of both genetic and environmental factors from the fetal stage through infancy. In this study, we analyzed a data subset from the South Kyushu and Okinawa (SKO) Study Area of Japan Environment and Children's Study (JECS) to determine the relationship of allergic diseases in infants with mothers' characteristics and/or infants' life habits, especially sleeping. A total of 3873 mother-infant pairs from the SKO Regional Center of JECS were included. The mothers responded to questionnaires in the first trimester of their pregnancy and the self-reported questionnaire when their infants were 1 year old. Student's t-test, chi-square test, trend test, and logistic regression analysis were carried out to analyze the associations between the infants' allergic diseases and the mothers' genetic characteristics and/or sleeping habits of infants. Maternal allergic diseases were significantly associated with increased infant allergy risk (OR: 1.93, 95% CI: 1.63-2.27). The number of allergic diseases of mothers was also significantly associated with infant allergy, and the trend test showed an increasing risk of infant allergy (p<0.001). Regarding infants' life habits, the infants who sleep in the prone position had a higher allergic disease risk than those who sleep in other positions (OR: 1.46, 95% CI: 1.17-1.83). These significant associations were observed regardless of the presence of allergy in mothers. This study suggests that the development of allergic diseases in infants may be caused by the multiple participation of both genetic and environmental factors.

Although sleep problems are well characterized in preschool- and school-age children with neurogenetic syndromes, little is known regarding the early emergence of these problems in infancy and toddlerhood. To inform syndrome-specific profiles and targets for intervention, we compared parent-reported sleep problems in infants and toddlers with Angelman syndrome (AS), Williams syndrome (WS), and Prader-Willi syndrome (PWS) with patterns observed among same-aged typically developing (TD) controls. Mothers of 80 children (18 AS, 19 WS, 19 PWS, and 24 TD) completed the Brief Infant Sleep Questionnaire. Primary dependent variables included (1) sleep onset latency, (2) total sleep duration, (3) daytime and nighttime sleep duration, and (4) sleep problem severity, as measured by both maternal impression and National Sleep Foundation guidelines. Sleep problems are relatively common in children with neurogenetic syndromes, with 41% of mothers reporting problematic sleep and 29% of children exhibiting abnormal sleep durations as per national guidelines. Across genetic subgroups, problems are most severe in children with AS and WS, particularly in relation to nighttime sleep duration. Although atypical sleep is characteristically reported in each syndrome later in development, infants and toddlers with PWS exhibited largely typical patterns, potentially indicating delayed onset of sleep problems in concordance with other medical features of PWS. Our findings suggest that sleep problems in neurogenetic syndromes emerge as early as infancy and toddlerhood, with variable profiles across genetic subgroups. This work underscores the importance of early sleep screenings as part of routine medical care of neurosyndromic populations and the need for targeted, syndrome-sensitive treatment.

To examine sleep-wake cycle (SWC) composition of healthy term infants in the immediate postnatal period using EEG, and investigate factors that might influence it. Multichannel video-EEG was recorded for a median of 61.9 min (IQR: 60.0-69.3). The absolute and relative scores of sleep states were calculated for each infant's recording. Parametric/non-parametric statistical tests and multiple linear regression analysis were used to investigate the influence of perinatal factors on SWC composition. Eighty healthy term infants aged 1-36 h were studied. A well-developed SWC was evident as early as within the first 6h after birth. The mean (SD) percentage of active sleep (AS) was 52.1% (12.9) and quiet sleep (QS) was 38.6% (12.5). AS was longer and QS shorter in infants delivered by elective caesarean section (CS) compared to infants delivered by vaginal delivery or emergency CS. This is the first large cohort EEG study that has quantified neonatal sleep. SWC is clearly present immediately after birth, it is dominated by AS, and is influenced by mode of delivery. This knowledge of the early neonatal EEG/SWC can be used as reference data for EEG studies of neurologically compromised infants.

2013-01-01

Iron-deficiency anemia (IDA) continues to be the most common single nutrient deficiency in the world. An estimated 20-25% of the world’s infants have IDA, with at least as many having iron deficiency without anemia. Infants are at particular risk due to rapid growth and limited dietary sources of iron. We found that infants with IDA showed different motor activity patterning in all sleep-waking states and several differences in sleep states organization. Sleep alterations were still apparent years after correction of anemia with iron treatment in the absence of subsequent IDA. We suggest that altered sleep patterns may represent an underlying mechanism that interferes with optimal brain functioning during sleep and wakefulness in former IDA children. PMID:20620103

Parental behaviors and sleep outcomes in infants and toddlers: a cross-cultural comparison.

2010-04-01

To assess the prevalence of parental behaviors and other factors of sleep ecology and to analyze their relationships with sleep outcomes in a large sample of children ages birth to 36months in multiple countries/regions. Parents of 29,287 infants and toddlers (48% boys; Australia, Canada, China, Hong Kong, India, Indonesia, Korea, Japan, Malaysia, New Zealand, Philippines, Singapore, Taiwan, Thailand, United Kingdom, United States, and Vietnam) completed an internet-based expanded version of the Brief Infant Sleep Questionnaire. Overall, there is a high level of parental involvement in sleep onset and sleep maintenance for young children, with significant differences in parenting behaviors across cultural groups. For predominantly-Caucasian, the most common behavior occurring at bedtime is falling asleep independently in own crib/bed (57%), compared to just 4% of those children living in predominantly-Asian regions. Parental behaviors and sleep ecology, including parental presence at sleep onset, bedtime, and bedtime routine, significantly explain a portion of the variance in sleep patterns. Overall, parental behaviors are more highly predictive of nighttime sleep outcomes in predominantly-Caucasian regions. Finally, parental involvement in sleep onset mediates the relationship between cosleeping and sleep outcomes. Overall, the best predictors of nighttime sleep are related to parental behaviors at bedtime and during the night. Furthermore, sleep disruption and decreased total sleep associated with bed sharing and room sharing are mediated by parental presence at bedtime. These findings provide additional support for addressing parental behaviors in behavioral interventions for infant and toddler sleep problems. Copyright 2010 Elsevier B.V. All rights reserved.

Parent-infant co-sleeping and its relationship to breastfeeding.

PubMed

Buswell, Stephanie D; Spatz, Diane L

2007-01-01

Co-sleeping can provide numerous benefits for both the parent(s) and the infant. Perhaps the greatest advantage lies in its promotion of breastfeeding, an act widely recognized for its benefits to both the mother and infant. However, risks also are associated with co-sleeping, prompting many researchers to examine the safety of its practice. Pediatric nurse practitioners need to be informed on issues related to co-sleeping in order to educate parents regarding its risks and benefits, to assess the safety of an established sleeping environment, and to be aware of its prevalence in their patient populations. A review of the literature is presented to inform pediatric nurse practitioners about varied definitions of co-sleeping, the reasons why some parents engage in the practice, cultural preferences for co-sleeping, associated risks and benefits, and its relationship to breastfeeding.

The present study evaluated whether the administration of cereals enriched with nutrients that are facilitators of sleep could help improve the sleep of infants who had sleep disorders at night time. Thirty infants aged 8-16 months with sleep disorders involving at least three nocturnal waking episodes took part in the study. They were given a night-time 'sleep facilitating cereal' product containing 225 mg tryptophan, 5.3 mg adenosine-5'-P, and 6.3 mg uridine-5'-P per 100 g of product. These cereals were given in a double-blind procedure lasting 5 weeks, with ingestion of the cereal between 18:00 and 06:00. In the control week, the children received a standard cereal (75 mg tryptophan/100 g product without nucleotides) dissolved in a standard formula milk (231.5 mg tryptophan, 2.6 mg adenosine-5'-P, 5 mg uridine-5'-P, per 100 g product). In one experimental week, the children received the night-time sleep facilitating cereal together with the standard formula milk. In another week, they received the sleep facilitating cereal together with a night milk specially formulated to attain the sleep rhythm (480 mg tryptophan, 8.8 mg uridine-5'-P, and 7.6 mg adenosine-5'-P per 100 g product). The three experimental weeks were separated by two wash-out weeks in which the milk and cereal administered was identical in composition to that of the control week. All the infants received a programmed writer actimeter which they wore continually, attached to their ankles, to record their motor activity. The recorded activity was used to calculate information about the time in bed, assumed sleep, actual sleep, sleep efficiency, sleep latency, immobility, and total activity. The infants receiving the enriched cereal during the time of darkness showed improvements in their sleep parameters, regardless of whether the milk they took at night was standard or enriched with tryptophan, adenosine-5'-P, and uridine-5'-P. In summary, the administration of enriched cereals led to an improvement in sleep, regardless of the type of infant milk used. These results support the concept of chrononutrition since they confirm that the sleep/wake rhythm can be influenced by diet.

Terrill, Philip I; Wilson, Stephen J; Suresh, Sadasivam; Cooper, David M

2009-01-01

Breathing patterns are characteristically different between active and quiet sleep states in infants. It has been previously identified that breathing dynamics are governed by a non-linear controller which implies the need for a nonlinear analytical tool. Further, it has been shown that quantified nonlinear variables are different between adult sleep states. This study aims to determine whether a nonlinear analytical tool known as recurrence plot analysis can characterize breath intervals of active and quiet sleep states in infants. Overnight polysomnograms were obtained from 32 healthy infants. The 6 longest periods each of active and quiet sleep were identified and a software routine extracted inter-breath interval data for recurrence plot analysis. Determinism (DET), laminarity (LAM) and radius (RAD) values were calculated for an embedding dimension of 4, 6, 8 and 16, and fixed recurrence of 0.5, 1, 2, 3.5 and 5%. Recurrence plots exhibited characteristically different patterns for active and quiet sleep. Active sleep periods typically had higher values of RAD, DET and LAM than for quiet sleep, and this trend was invariant to a specific choice of embedding dimension or fixed recurrence. These differences may provide a basis for automated sleep state classification, and the quantitative investigation of pathological breathing patterns.

OBJECTIVE--To determine the relation between sleeping position and quantity of bedding and the risk of sudden unexpected infant death. DESIGN--A study of all infants dying suddenly and unexpectedly and of two controls matched for age and date with each index case. The parents of control infants were interviewed within 72 hours of the index infant's death. Information was collected on bedding, sleeping position, heating, and recent signs of illness for index and control infants. SETTING--A defined geographical area comprising most of the county of Avon and part of Somerset. SUBJECTS--72 Infants who had died suddenly and unexpectedly (of whom 67 had died from the sudden infant death syndrome) and 144 control infants. RESULTS--Compared with the control infants the infants who had died from the sudden infant death syndrome were more likely to have been sleeping prone (relative risk 8.8; 95% confidence interval 7.0 to 11.0; p less than 0.001), to have been more heavily wrapped (relative risk 1.14 per tog above 8 tog; 1.03 to 1.28; p less than 0.05), and to have had the heating on all night (relative risk 2.7; 1.4 to 5.2; p less than 0.01). These differences were less pronounced in the younger infants (less than 70 days) than the older ones. The risk of sudden unexpected death among infants older than 70 days, nursed prone, and with clothing and bedding of total thermal resistance greater than 10 tog was increased by factors of 15.1 (2.6 to 89.6) and 25.2 (3.7 to 169.0) respectively compared with the risk in infants of the same age nursed supine or on their side and under less than 6 tog of bedding. CONCLUSIONS--Overheating and the prone position are independently associated with an increased risk of sudden unexpected infant death, particularly in infants aged more than 70 days. Educating parents about appropriate thermal care and sleeping position of infants may help to reduce the incidence of the sudden infant death syndrome. PMID:2390588

Commentary: Sleep in German infants--the "cult" of independence.

PubMed

Valentin, Stephan R

2005-01-01

Significant cultural variations exist in sleep practices for young children, including bedtime rituals and routines, soothing techniques, and cosleeping. This study examined parenting styles at bedtime and sleep behavior in a group of German infants. The results are compared with sleep practices of other western European countries. German parents of 50 boys and 50 girls 6 to 30 months old. Parents were asked to fill out a questionnaire about the sleep behavior of their child. Personal interviews with the parents were conducted to augment the survey results; in selected cases, bedtime routines were filmed. The infants in this sample largely slept in their own bed in a separate room. Bedtime rituals were common and in general characterized by parents maintaining behavioral distance from the infants during the bedtime routine. However, parenting style was likely to become more "proximal" (close) in response to bedtime refusal and nocturnal infant crying. A majority of parents (79%) used lullabies as part of the bedtime ritual, and the use of a sleep aid was very common (80%). As is the case with most cultures, German bedtime parenting practices tend to reflect parenting values and beliefs associated with their specific culture. The parenting style at bedtime in this group of infants in general seemed less rigid and less distancing than bedtime rituals typically described in other northern European countries and may represent more of a synthesis of parenting styles across various Western cultures.

This paper reports a study to describe changes in parents' distress after a family-centred intervention for sleep problems of infants. Infant sleep problems are common and are related to depressive symptoms in mothers, but their impact on fathers has rarely been studied. Because childhood sleep problems and parental distress are associated, their interdependence should be recognized in research and in paediatric sleep practice. All children hospitalized for sleep problems in a hospital in Iceland in 1997-1998 and their parents were studied using a pre- and post-test quasi-experimental design. The sample consisted of 33 infants (6-23 months of age), 33 mothers and 30 fathers. Parents' distress was assessed before and after treatment with regard to: (1) fatigue and resulting symptom distress; (2) parenting stress; (3) state-anxiety; and (4) depressive symptoms. Infants were treated for a variety of sleep problems by a paediatric nurse. The parents were simultaneously treated for distress by either the paediatric nurse or a specialist, depending on the nature of their problems. Mothers and fathers experienced a high degree of distress before the intervention, with no significant difference between them. Two months after the intervention both parents' distress had significantly improved. Parents' degree of distress was at a psychopathological level before the intervention but was reduced to population norms 2 months after the intervention. The paediatric nurse intervention was sufficient to reduce distress for 83% of parents. Health care professionals who care for infants with sleep problems should pay attention to the distressed responses of parents and support their recovery. An intervention such as that described here could be used by nurses for this purpose.

Infant sleeping arrangements and cultural values among contemporary Japanese mothers

2014-01-01

We examined infant sleeping arrangements and cultural values of Japanese mothers in 2008 and 2009. Based on Greenfield's theory of social change and human development, we predicted that social change in Japan over the last decades (higher economic and education level, urbanization, complex technology, more women in the work force) would lead to a decline in mother-infant co-sleeping, compared with published findings concerning Japanese sleeping arrangements in the 1960s and 1980s. We also predicted that the practice of having babies sleep in their own beds and/or own rooms would be supported by ethnotheories stressing infant independence and other values adaptive in an urban, technologically sophisticated, relatively wealthy, and highly educated populace. Fifty-one Japanese mothers' comments posted on Internet parenting forums were analyzed. Contrary to our hypothesis, co-sleeping was as frequent among Japanese mothers in 2008-2009 as it had been in the 1960s and 1980s. However, analysis of the values of co-sleeping mothers revealed frequent discrepancies between values and practices. In contrast, the minority of mothers whose babies slept alone in a separate room all expressed consonant values. Our qualitative analysis indicates that it is not always easy for Japanese mothers to construct values for child rearing and gender roles that integrate traditional infant care practices with current sociodemographic conditions.

To investigate thermal balance of infants in a Mongolian winter, and compare the effects of traditional swaddling with an infant sleeping-bag in apartments or traditional tents (Gers). A substudy within a randomised controlled trial. Community in Ulaanbaatar, Mongolia. A stratified randomly selected sample of 40 swaddled and 40 non-swaddled infants recruited within 48 h of birth. Sleeping-bags and baby outfits of total thermal resistance equivalent to that of swaddled babies. Digital recordings of infants' core, peripheral, environmental and microenvironmental temperatures at 30-s intervals over 24 h at ages 1 month and 3 months. In Gers, indoor temperatures varied greatly (<0->25°C), but remained between 20°C and 22°C, in apartments. Despite this, heavy wrapping, bed sharing and partial head covering, infant core and peripheral temperatures were similar and no infants showed evidence of significant heat or cold stress whether they were swaddled or in sleeping-bags. At 3 months, infants in sleeping-bags showed the 'mature' diurnal pattern of a fall in core temperature after sleep onset, accompanied by a rise in peripheral temperature, with a reverse pattern later in the night, just before awakening. This pattern was not related to room temperature, and was absent in the swaddled infants, suggesting that the mature diurnal pattern may develop later in them. No evidence of cold stress was found. Swaddling had no identifiable thermal advantages over sleeping-bags during the coldest times, and in centrally heated apartments could contribute to the risk of overheating during the daytime.

We investigated the association of infants' sleep and awake positioning with motor milestone acquisition as measured by the Alberta Infant Motor Scale (AIMS). Participants were 30 very-low-birthweight (VLBW) infants with preterm white matter disease (PTWMD; 21 males, nine females; mean birthweight [BW] 1,129 g [SD 338]; mean gestational age [GA] 28 wks [SD 2.44]); 21 VLBW infants without preterm WMD (PT; 13 males, eight females; mean BW 1,107 g [SD 370]; mean GA 28.05 wks [SD 2.21]); and 17 term infants (Term; seven males, 10 females; mean BW 3,565 g [SD 382]; mean GA 40 wks [SD 1.31]). Testing occurred at 1, 5, and 9 months of age (corrected for prematurity). Preferred positions during sleeping, playing, and feeding were obtained through parent interview. These positions and group were the independent variables. Prone sleeping was significantly and positively associated with motor development at all ages (1 mo: p=0.005; 5 mo: p=0.011; 9 mo: p=0.040). At 5 months, prone sleeping and playing were significantly and positively associated with AIMS scores (prone sleeping, p=0.016; prone playing, p=0.047). However, group was negatively associated with preterm white matter disease, with the PTWMD group having significantly lower AIMS scores than the Term group (p=0.029). At 9 months, sitting playing and group membership were significantly associated with AIMS scores (sitting playing, p=0.005; group, p=0.012). Prone positioning should be encouraged for awake time, particularly for infants with preterm white matter disease.

Randomized trials have demonstrated the short- to medium-term effectiveness of behavioral infant sleep interventions. However, concerns persist that they may harm children's emotional development and subsequent mental health. This study aimed to determine long-term harms and/or benefits of an infant behavioral sleep program at age 6 years on (1) child, (2) child-parent, and (3) maternal outcomes. Three hundred twenty-six children (173 intervention) with parent-reported sleep problems at age 7 months were selected from a population sample of 692 infants recruited from well-child centers. The study was a 5-year follow-up of a population-based cluster-randomized trial. Allocation was concealed and researchers (but not parents) were blinded to group allocation. Behavioral techniques were delivered over 1 to 3 individual nurse consultations at infant age 8 to 10 months, versus usual care. The main outcomes measured were (1) child mental health, sleep, psychosocial functioning, stress regulation; (2) child-parent relationship; and (3) maternal mental health and parenting styles. Two hundred twenty-five families (69%) participated. There was no evidence of differences between intervention and control families for any outcome, including (1) children's emotional (P = .8) and conduct behavior scores (P = .6), sleep problems (9% vs 7%, P = .2), sleep habits score (P = .4), parent- (P = .7) and child-reported (P = .8) psychosocial functioning, chronic stress (29% vs 22%, P = .4); (2) child-parent closeness (P = .1) and conflict (P = .4), global relationship (P = .9), disinhibited attachment (P = .3); and (3) parent depression, anxiety, and stress scores (P = .9) or authoritative parenting (63% vs 59%, P = .5). Behavioral sleep techniques have no marked long-lasting effects (positive or negative). Parents and health professionals can confidently use these techniques to reduce the short- to medium-term burden of infant sleep problems and maternal depression.

Naps promote flexible memory retrieval in 12-month-old infants.

2016-11-01

Flexibility in applying existing knowledge to similar cues is a corner stone of memory development in infants. Here, we examine the effect of sleep on the flexibility of memory retrieval using a deferred imitation paradigm. Forty-eight 12-month-old infants were randomly assigned to either a nap or a no-nap demonstration condition (scheduled around their natural daytime sleep schedule) or to a baseline control condition. In the demonstration conditions, infants watched an experimenter perform three target actions on a hand puppet. Immediately afterwards, infants were allowed to practice the target actions three times. In a test session 4-hr later, infants were given the opportunity to reproduce the actions with a novel hand puppet differing in color from the puppet used during the demonstration session. Only infants in the nap-condition performed significantly more target actions than infants in the baseline control condition. Furthermore, they were faster to carry out the first target action than infants in the no-nap condition. We conclude that sleep had a facilitative effect on infants' flexibility of memory retrieval. © 2016 Wiley Periodicals, Inc.

What affects the age of first sleeping through the night?

PubMed

Adams, S M; Jones, D R; Esmail, A; Mitchell, E A

2004-03-01

To ascertain the age at which an infant first sleeps regularly through the night and the factors affecting this age. A representative cross sectional sample of 700 infants in south-east England were studied. Information was collected on 511 (73.0%) of the infants by parental interview. Obstetric records were also examined. Fifty per cent of babies slept through by 8 weeks and 75% by 12 weeks. Multivariate survival analysis used to investigate 61 potential factors found that a heavier birthweight, female gender and co-sleeping less than 2 hours or not at all; younger mothers, school leaving age less than 17 years, stress factors (divorce and no separation from partner for more than a month in the last 12 months); no central heating, and the baby not sharing a room with siblings were associated with an earlier age at which an infant first sleeps through the night. Little of the variation between children in age of first sleeping through the night could be explained by these nine factors.

Infant rolling abilities--the same or different 20 years after the back to sleep campaign?

PubMed

Darrah, Johanna; Bartlett, Doreen J

2013-05-01

To compare the order and age of emergence of rolling prone to supine and supine to prone before the introduction of back to sleep guidelines and 20 years after their introduction. The original normative data for the Alberta Infant Motor Scale (AIMS) were collected just prior to the introduction of back to sleep guidelines in 1992. Currently these norms are being re-evaluated. Data of rolling patterns of infants 36 weeks of age or younger from the original sample (n=1114) and the contemporary sample (n=351) were evaluated to compare the sequence of appearance of prone to supine and supine to prone rolls (proportion of infants passing each roll) and the ages of emergence (estimated age when 50% of infants passed each roll). The sequence of emergence and estimated age of appearance of both rolling directions were similar between the two time periods. The introduction of the supine sleep position to reduce the prevalence of Sudden Infant Death Syndrome (SIDS) has not altered the timing or sequence of infant rolling abilities. This information is valuable to health care providers involved in the surveillance of infants' development. Original normative age estimates for these two motor abilities are still appropriate.

Prenatal exposure to alcohol can result in a range of neurobehavioral impairments and physical abnormalities. The term fetal alcohol spectrum disorders (FASD) encompasses the outcomes of prenatal alcohol exposure (PAE), the most severe of which is fetal alcohol syndrome (FAS). These effects have lifelong consequences, placing a significant burden on affected individuals, caregivers, and communities. Caregivers of affected children often report that their child has sleep problems, and many symptoms of sleep deprivation overlap with the cognitive and behavioral deficits characteristic of FASD. Alcohol-exposed infants and children demonstrate poor sleep quality based on measures of electroencephalography (EEG), actigraphy, and questionnaires. These sleep studies indicate a common theme of disrupted sleep pattern, more frequent awakenings, and reduced total sleep time. However, relatively little is known about circadian rhythm disruption, and the neurobehavioral correlates of sleep disturbance in individuals with PAE. Furthermore, there is limited information available to healthcare providers about identification and treatment of sleep disorders in patients with FASD. This review consolidates the findings from studies of infant and pediatric sleep in this population, providing an overview of typical sleep characteristics, neurobehavioral correlates of sleep disruption, and potential avenues for intervention in the context of PAE.

To examine 1) parent-provider communication about pediatric health/safety guidelines, 2) trust in child's provider, 3) comfort discussing guidelines, 4) agreement with guideline advice, 5) self-efficacy following guidelines, and their impact on guideline adherence. 256 parents of children ages 0-6 completed an online survey about sunscreen use, newborn Vitamin K injections, influenza vaccination, routine vaccination, car seats, infant safe sleep, furniture anchoring, large trampoline use, and firearm safety. Multivariable models regressed: 1) communication about each guideline on parents' corresponding guideline adherence; 2) trust, comfort discussing guidelines, agreement with guideline advice, self-efficacy, on parents' total guideline adherence. Communication about furniture anchoring (OR = 2.26), sunscreen (OR = 5.28), Vitamin K injections (OR = 3.20), influenza vaccination (OR = 13.71), routine vaccination (OR = 6.43), car seats (OR = 6.15), and infant safe sleep (OR = 3.40) related to corresponding guideline adherence (ps < 0.05). Firearm safety communication was not related to adherence (OR = 1.11, n.s.). Trampoline communication related to lower likelihood of trampoline guideline adherence (OR = 0.24, p = 0.001). Agreement with guideline advice (β = 0.35), trust (β = 0.34), self-efficacy (β = 0.45), comfort discussing guidelines (β = 0.35) positively related to total guideline adherence (ps < 0.001). Findings underscore the importance of provider communication about health/safety guidelines. Providers should respectfully engage and build relationships with parents to support health/safety guideline adherence. Copyright © 2018. Published by Elsevier B.V.

This longitudinal study assessed the role of early sleep patterns in predicting attention regulation and behavior problems. Sleep of 43 infants was assessed using actigraphy at 12 months of age and then reassessed when the children were 3-4 years old. During this follow-up, their attention regulation and behavior problems were also assessed using a computerized test and parental reports. Lower quality of sleep in infancy significantly predicted compromised attention regulation and behavior problems. These findings underscore the need to identify and treat early sleep problems.

Cross-sectional studies suggest an association between eczema and mental health problems, possibly modified by sleeping problems, but prospective evidence is missing. We aimed to prospectively investigate the relationship between infant eczema (within first 2 years of age), infant sleeping problems (within first 2 years of age), and the risk of mental health problems at 10 years of age. Between 1997 and 1999, a population-based birth cohort was recruited in Munich, Leipzig, Wesel, and Bad Honnef, Germany, and followed until 10 years of age. Physician-diagnosed eczema, parent-reported sleeping problems, and known environmental risk factors for atopy were regularly assessed until 10 years of age. Mental health was measured using the Strengths and Difficulties Questionnaire (parent version) at 10 years of age. We applied logistic regression modeling adjusting for environmental and lifestyle factors, allergic comorbidity, and family history of eczema. From the original cohort of 3097 neonates, 1658 (54%) were followed until age 10, while 1578 (51%) were eligible for analysis. In the fully adjusted model, children with infant eczema were at increased risk of hyperactivity/inattention at 10 years of age [odds ratio (OR) 1.78; 95% confidence interval (95% CI) 1.02-3.09]. Infant eczema with concurrent sleeping problems predicted emotional problems [OR 2.63; 95% confidence interval (95% CI) 1.20-5.76] and conduct problems (OR 3.03; 95% CI 1.01-9.12) at 10 years of age. Infant eczema with concurrent sleeping problems appears to be a risk factor for the development of mental health problems. © 2010 John Wiley & Sons A/S.

The Association of Daytime Maternal Napping and Exercise With Nighttime Sleep in First-Time Mothers Between 3 and 6 Months Postpartum.

2016-10-19

This study investigated the relationship of daytime maternal napping, exercise, caffeine, and alcohol intake to objective and subjective sleep indices. Sixty healthy, nondepressed, first-time mothers between 3 and 6 months postpartum. Seven consecutive days of online behavior diaries, sleep diaries, and wrist actigraphy, collecting Total Sleep Time (TST), Sleep Onset Latency (SOL), and Wake After Sleep Onset (WASO). After controlling for infant age, employment status, infant feeding method, and infant sleeping location, mixed linear models showed that longer average exercise durations were associated with longer average TST, and longer average nap durations were associated with longer average WASO durations. Significant within-person differences in TST and SOL were also observed, such that, on days when participants exercised and napped longer than average, their respective TST and SOL durations that night were longer. Shorter nap durations and longer exercise durations were associated with longer TST, shorter SOL, and reduced WASO. Even small changes in daily exercise and napping behaviors could lead to reliable improvements in postpartum maternal sleep.

Substance P (SP) is a neuropeptide transmitter found in sensory neurons of the central nervous system and related to pain sensation and respiratory regulation. Some reports claim an increase in SP in the brains of SIDS victims, so the correlation between SP and sleep apnea was investigated here. Among 27,000 infants studied prospectively to characterize their sleep-wake behavior, 38 infants died under 6 months of age, which included 26 cases of Sudden Infant Death Syndrome (SIDS). All the infants had been recorded during one night in a pediatric sleep laboratory some 3 to 12 weeks before death. The frequency and duration of sleep apnea were analyzed. Brainstem material was collected and immunohistochemistry for SP was carried out. The density of SP positive fibers was measured in the nucleus spinal and mesencephalic nervi trigemini and nucleus parabranchialis in the brainstem of abovementioned cases. Correlation analyses were carried out between the density of SP and the data of sleep apnea. There was no SIDS specific correlation of SP through the above-listed parts of the midbrain with frequency and duration of sleep apnea. There was no significant association between the SP findings and apnea data in SIDS; this is not in agreement with the association of apnea in pathophysiology of SIDS.

Preferred sleep position and gross motor achievement in early infancy.

2009-06-01

The aim of this study was to assess the effect of an infant's favoured position on their motor development at the age of six months. Seventy-five full-term infants were prospectively observed at home for their preferred sleep, awake, play and uninterrupted positions. A parental log was completed daily and then weekly up to the age of six months, when the Alberta Infant Motor Scale (AIMS) was administered. No significant relationship between the preferred or sleep positions as well as the awake and mutual play positions and gross motor developmental attainment at six months of age was noted. A significant change in the preferred recumbent posture with increased prone positioning both during sleep and awake time over the first six months was noted. A balanced positioning policy while awake, regardless of the infant's preference while recumbent, is not associated with gross motor delay.

THE DEVELOPMENT OF SLEEP-WAKE RHYTHMS AND THE SEARCH FOR ELEMENTAL CIRCUITS IN THE INFANT BRAIN

PubMed Central

Blumberg, Mark S.; Gall, Andrew J.; Todd, William D.

2014-01-01

Despite the predominance of sleep in early infancy, developmental science has yet to play a major role in shaping concepts and theories about sleep and its associated ultradian and circadian rhythms. Here we argue that developmental analyses help us to elucidate the relative contributions of the brainstem and forebrain to sleep-wake control and to dissect the neural components of sleep-wake rhythms. Developmental analysis also makes it clear that sleep-wake processes in infants are the foundation for those of adults. For example, the infant brainstem alone contains a fundamental sleep-wake circuit that is sufficient to produce transitions among wakefulness, quiet sleep, and active sleep. Also, consistent with the requirements of a “flip-flop” model of sleep-wake processes, this brainstem circuit supports rapid transitions between states. Later in development, strengthening bidirectional interactions between the brainstem and forebrain contribute to the consolidation of sleep and wake bouts, the elaboration of sleep homeostatic processes, and the emergence of diurnal or nocturnal circadian rhythms. The developmental perspective promoted here critically constrains theories of sleep-wake control and provides a needed framework for the creation of fully realized computational models. Finally, with a better understanding of how this system is constructed developmentally, we will gain insight into the processes that govern its disintegration due to aging and disease. PMID:24708298

Preterm birth impairs the infant's stress response due to interruption of autonomic nervous system (ANS) development. Preterm infants demonstrate a prolonged and aberrant sympathetic response to stressors. ANS development may be promoted by massage therapy (MT), which has been shown to improve stress response in preterm infants. The aim of this study was to compare preterm infant ANS function and stress response during sleep and caregiving epochs, as measured by heart rate variability (HRV), after two weeks of twice-daily MT. A subset of participants from a larger randomized, masked, controlled trial was used. Twenty-one infants (8 males and 13 females) from a larger study of 37 medically stable preterm infants were studied. The infants were receiving full volume enteral feedings with a mean post-menstrual age of 31.4 (MT) and 30.9 (control) weeks. Low to high frequency (LF:HF) ratio of HRV was the outcome of interest. There was a significant group×time×sex interaction effect (p<.05). Male control infants demonstrated a significant decline in LF:HF ratio from baseline to the second caregiving epoch, suggesting decreased mobilization of sympathetic nervous system response when exposed to stressors. Male MT infants demonstrated increased LF:HF ratio during caregiving and decreased LF:HF ratio during sleep epochs, suggesting improved ANS function, although this was not statistically significant. LF:HF ratio was similar in female MT and female control infants during caregiving and sleep. Control males had decreased HRV compared to MT males. There was no difference in HRV between MT and control females. Copyright © 2013 Elsevier Ltd. All rights reserved.

Small for gestational age infants have an increased risk of immediate complications, short-term morbidity and mortality, and long-term neurologic and metabolic disorders in adulthood. Previous research has shown that reduced sleep duration is a risk factor for SGA birth. However, only a few studies have evaluated maternal sleep as a risk factor for SGA birth. In the present study, we investigated the relationship between the amount and quality of mothers' sleep and infants' birth weight. This cohort study (n = 8631) used data from the Japan Environment and Children's Study, an ongoing cohort study that began in January 2011. Data on sleep status (sleep duration and one indicator of sleep quality) and potential confounding factors were recorded. A log-binomial regression model was used to estimate the risk of small for gestational age birth, and the results were expressed as risk ratios and their respective 95% confidence interval. No significant results were observed for sleep duration or tiredness upon waking. Neither the amount nor the quality of mothers' sleep was associated with the risk of small for gestational age birth.

1977-11-01

Thirteen all-night recordings were obtained from 3 infant pigtailed (Macaca nemestrina) monkeys raised on a cloth surrogate mother and under conditions of social isolation. Totally implantable biotelemetry systems were used to record the sleep physiology from the unrestrained animals. Sleep stages and night-to-night variability were virtually identical to values previously found in 8 mother-reared group-living infants. Sustained alterations in the early rearing enviroment, even though considerably modifying the organism's development, did not appear to result in differences in sleep organization.

To conduct a systematic review and meta-analyses to assess the effect of manual therapy interventions for healthy but unsettled, distressed and excessively crying infants and to provide information to help clinicians and parents inform decisions about care. We reviewed published peer-reviewed primary research articles in the last 26 years from nine databases (Medline Ovid, Embase, Web of Science, Physiotherapy Evidence Database, Osteopathic Medicine Digital Repository , Cochrane (all databases), Index of Chiropractic Literature, Open Access Theses and Dissertations and Cumulative Index to Nursing and Allied Health Literature). Our inclusion criteria were: manual therapy (by regulated or registered professionals) of unsettled, distressed and excessively crying infants who were otherwise healthy and treated in a primary care setting. Outcomes of interest were: crying, feeding, sleep, parent-child relations, parent experience/satisfaction and parent-reported global change. Nineteen studies were selected for full review: seven randomised controlled trials, seven case series, three cohort studies, one service evaluation study and one qualitative study.We found moderate strength evidence for the effectiveness of manual therapy on: reduction in crying time (favourable: -1.27 hours per day (95% CI -2.19 to -0.36)), sleep (inconclusive), parent-child relations (inconclusive) and global improvement (no effect). The risk of reported adverse events was low: seven non-serious events per 1000 infants exposed to manual therapy (n=1308) and 110 per 1000 in those not exposed. Some small benefits were found, but whether these are meaningful to parents remains unclear as does the mechanisms of action. Manual therapy appears relatively safe.

Family and cultural influences on sleep development.

Giannotti, Flavia; Cortesi, Flavia

2009-10-01

Sleep is a biopsychosocial process that is influenced by the complex interaction of biologic rhythms, including sleep homeostatic mechanisms, chronobiologic factors, parenting, and temperament. However, family structure, culturally specific values, and beliefs are all elements that impact the ecology of a child's sleep. Dramatic demographic changes in many countries have been witnessed in recent years, which have resulted in health professionals and pediatricians being confronted with families of widely differing cultural origins. Attitudes and beliefs on infant sleeping strongly influence whether or not infant sleep behavior is perceived as problematic. Thus, it is advantageous to explore a child's sleep behavior in a multicultural setting. Cultural comparisons are of intrinsic value because they allow not only a better understanding of sleep in different contexts but also an evaluation of the eventual benefits and consequences of different cultural sleep practices. This article provides an overview of some specific sleep-related behaviors and practices highly influenced by different cultural contexts.

Application of recurrence quantification analysis to automatically estimate infant sleep states using a single channel of respiratory data.

2012-08-01

Previous work has identified that non-linear variables calculated from respiratory data vary between sleep states, and that variables derived from the non-linear analytical tool recurrence quantification analysis (RQA) are accurate infant sleep state discriminators. This study aims to apply these discriminators to automatically classify 30 s epochs of infant sleep as REM, non-REM and wake. Polysomnograms were obtained from 25 healthy infants at 2 weeks, 3, 6 and 12 months of age, and manually sleep staged as wake, REM and non-REM. Inter-breath interval data were extracted from the respiratory inductive plethysmograph, and RQA applied to calculate radius, determinism and laminarity. Time-series statistic and spectral analysis variables were also calculated. A nested cross-validation method was used to identify the optimal feature subset, and to train and evaluate a linear discriminant analysis-based classifier. The RQA features radius and laminarity and were reliably selected. Mean agreement was 79.7, 84.9, 84.0 and 79.2 % at 2 weeks, 3, 6 and 12 months, and the classifier performed better than a comparison classifier not including RQA variables. The performance of this sleep-staging tool compares favourably with inter-human agreement rates, and improves upon previous systems using only respiratory data. Applications include diagnostic screening and population-based sleep research.

Entropy Information of Cardiorespiratory Dynamics in Neonates during Sleep.

Lucchini, Maristella; Pini, Nicolò; Fifer, William P; Burtchen, Nina; Signorini, Maria G

Sleep is a central activity in human adults and characterizes most of the newborn infant life. During sleep, autonomic control acts to modulate heart rate variability (HRV) and respiration. Mechanisms underlying cardiorespiratory interactions in different sleep states have been studied but are not yet fully understood. Signal processing approaches have focused on cardiorespiratory analysis to elucidate this co-regulation. This manuscript proposes to analyze heart rate (HR), respiratory variability and their interrelationship in newborn infants to characterize cardiorespiratory interactions in different sleep states (active vs. quiet). We are searching for indices that could detect regulation alteration or malfunction, potentially leading to infant distress. We have analyzed inter-beat (RR) interval series and respiration in a population of 151 newborns, and followed up with 33 at 1 month of age. RR interval series were obtained by recognizing peaks of the QRS complex in the electrocardiogram (ECG), corresponding to the ventricles depolarization. Univariate time domain, frequency domain and entropy measures were applied. In addition, Transfer Entropy was considered as a bivariate approach able to quantify the bidirectional information flow from one signal (respiration) to another (RR series). Results confirm the validity of the proposed approach. Overall, HRV is higher in active sleep, while high frequency (HF) power characterizes more quiet sleep. Entropy analysis provides higher indices for SampEn and Quadratic Sample entropy (QSE) in quiet sleep. Transfer Entropy values were higher in quiet sleep and point to a major influence of respiration on the RR series. At 1 month of age, time domain parameters show an increase in HR and a decrease in variability. No entropy differences were found across ages. The parameters employed in this study help to quantify the potential for infants to adapt their cardiorespiratory responses as they mature. Thus, they could be useful as early markers of risk for infant cardiorespiratory vulnerabilities.

Maternal depression is an established risk for adverse child development. Two thirds of clinically significant depressive symptoms occur in mothers reporting an infant sleep problem. We aimed to determine the long-term effects of a behavioral intervention for infant sleep problems on maternal depression and parenting style, as well as on child mental health and sleep, when the children reached 2 years of age. We conducted a cluster-randomized trial in well-child centers across 6 government areas of Melbourne, Australia. Participants included 328 mothers reporting an infant sleep problem at 7 months, drawn from a population sample (N = 739) recruited at 4 months. We compared the usual well-child care (n = 154) versus a brief behavior-modification program designed to improve infant sleep (n = 174) delivered by well-child nurses at ages 8 to 10 months and measured maternal depression symptoms (Edinburgh Postnatal Depression Scale); parenting practices (Parent Behavior Checklist); child mental health (Child Behavior Checklist); and maternal report of a sleep problem (yes or no). At 2 years, mothers in the intervention group were less likely than control mothers to report clinical depression symptoms: 15.4% vs 26.4% (Edinburgh Postnatal Depression Scale community cut point) and 4.2% vs 13.2% (Edinburgh Postnatal Depression Scale clinical cut point). Neither parenting style nor child mental health differed markedly between the intervention and control groups. A total of 27.3% of children in the intervention group versus 32.6% of control children had a sleep problem. The sleep intervention in infancy resulted in sustained positive effects on maternal depression symptoms and found no evidence of longer-term adverse effects on either mothers' parenting practices or children's mental health. This intervention demonstrated the capacity of a functioning primary care system to deliver effective, universally offered secondary prevention.

Few objective data are available regarding infants’ night waking behaviors and the development of self-soothing during the first year of life. This cross-sectional study examined 80 infants in one of four age groups (3, 6, 9, or 12 mo) for four nights by using videosomnography to code nighttime awakenings and parent-child interactions. A large degree of variability was observed in parents’ putting the infant to bed awake or asleep and in responding to vocalizations after nighttime awakenings. Most infants woke during the night at all ages observed. Younger infants tended to require parental intervention at night to return to sleep, whereas older infants exhibited a greater proportion of self-soothing after nighttime awakenings. However, even in the 12-month-old group, 50% of infants typically required parental intervention to get back to sleep after waking. Results emphasize the individual and contextual factors that effect the development of self-soothing behavior during the first year of life. PMID:11530895

Maturation of Heart Rate and Blood Pressure Variability during Sleep in Term-Born Infants

2012-01-01

Study Objectives: Abnormal blood pressure control is implicated in the sudden infant death syndrome (SIDS). However, no data exist on normal development of blood pressure control during infancy. This study assessed maturation of autonomic control of blood pressure and heart rate during sleep within the first 6 months of life. Participants: Term infants (n = 31) were studied longitudinally at 2-4 weeks, 2-3 months, and 5-6 months postnatal age. Interventions: Infants underwent daytime polysomnography at each age studied. Blood pressure and heart rate were recorded during quiet (QS) and active (AS) sleep in undisturbed baseline and head-up tilt conditions. Measurements and Results: Autonomic control was assessed using spectral indices of blood pressure and heart rate variability (BPV and HRV) in ranges of low frequency (LF, reflecting sympathetic + parasympathetic activity) and high frequency (HF, parasympathetic activity), total power (LF+HF), and LF/HF ratio (sympathovagal balance). With increasing postnatal age and predominantly during QS, HRV-LF, HRV-HF, and HRV total power increased, while HRV-LF/HF decreased. BPV-LF/HF also decreased with postnatal age. All changes were evident in both baseline and head-up tilt conditions. BPV-LF and BPV total power during tilts were markedly reduced in QS versus AS at each age. Conclusions: In sleeping infants, sympathetic vascular modulation of the circulation decreases with age, while parasympathetic control of heart rate is strengthened. These normative data will aid in the early identification of conditions where autonomic function is impaired, such as in SIDS. Citation: Yiallourou SR; Sands SA; Walker AM; Horne RSC.

To describe the efficacy and safety of chloral hydrate sedation in infants for pulmonary function tests. All sedation attempts for pulmonary function tests in infants carried out between June 2007 and August 2014 were evaluated. Obstructive sleep apnea and heart disease were contraindications to the exams. Anthropometric data, exam indication, used dose, outcomes of sedation and clinical events were recorded and described. The sedation attempts in 277 infants (165 boys) with a median age of 51.5 weeks of life (14 to 182 weeks) were evaluated. The main indication for the tests was recurrent wheezing (56%) and the chloral hydrate dose ranged from 50 to 80mg/kg (orally). Eighteen (6.5%) infants had some type of clinical complication, with the most frequent being cough and/or airway secretion (1.8%); respiratory distress (1.4%) and vomiting (1.1%). A preterm infant had bradycardia for approximately 15 minutes, which was responsive to tactile stimulation. All observed adverse effects were transient and there was no need for resuscitation or use of injectable medications. The data demonstrated that chloral hydrate at the employed doses is a safe and effective medicament for sedation during short procedures in infants, such as pulmonary function tests. Because of the possibility of severe adverse events, recommendations on doses and contraindications should be strictly followed and infants should be monitored by trained staff.

2008-03-01

A study, entitled Evaluation of an Intervention Aimed at Resolving Behavioural Sleep Problems in 6- to 12-month-old Infants: A Pilot Study, was undertaken to evaluate the efficacy of a behavioural sleep intervention. This descriptive qualitative study aimed to describe parents' perceptions of the sleep intervention and any burden associated with participating in the study. Fourteen of the 35 families who had participated in the quantitative study were interviewed. Respondents comprised well-educated, middle-class and mixed-ethnicity families. Data were collected through semi-structured interviews, with open-ended trigger questions, and were analysed using inductive content analysis. Nine themes, which subsumed a number of categories, were constructed. Parents changed their perspectives about sleep and parenting styles; they experienced many challenges and inadvertent benefits; and they welcomed a structured framework for assisting with sleep problems. The parents fitted intervention strategies into their realities; many factors interfered with their success; and their support systems and their expectations of the study varied. These parents' previous education about normal infant sleep cycles and behavioural sleep problems was inadequate. The parents who were able to use the structured framework, flexible strategies and access to healthcare professionals for problem solving not only excelled in resolving their infants' sleep problems, but also gained confidence about their parenting skills and success.

Why is a prone sleeping position dangerous for certain infants?

PubMed

Byard, Roger W; Bright, Fiona; Vink, Robert

2018-03-01

The prone (face down) sleeping position is known to be associated with a significantly increased risk of sudden and unexpected death in infancy (sudden infant death syndrome or SIDS), however, the reasons for this are unclear. Suggested mechanisms have involved suffocation from occlusion of the external airways by soft bedding/pillows or from flattening of the nose with backward displacement of the tongue, rebreathing of carbon dioxide, blunting of arousal responses with decreased cardiac responses to auditory stimulation, diaphragmatic splinting or fatigue, lowering of vasomotor tone with tachycardia, nasopharyngeal bacterial overgrowth, overheating, alteration of sleep patterns, compromise of cerebral blood flow and upper airway obstruction from distortion of nasal cartilages. Recent studies have, however, shown a significant reduction in substance P in the inferior portion of the olivo-cerebellar complex in SIDS infants which is crucial for the integration of motor and sensory information for the control of head and neck movement. This deficit may explain why some infants are not able to move their faces away from potentially dangerous sleeping environments.

The significance of minor myocardial inflammatory infiltrates and viral detection in SIDS is controversial. We retrospectively compared the demographic profiles, myocardial inflammation, cardiomyocyte necrosis, and myocardial virus detection in infants who died of SIDS in a safe sleep environment, accidental suffocation, or myocarditis. Formalin-fixed, paraffin-embedded myocardial sections were semiquantitatively assessed for CD3 lymphocytes and CD68 macrophages using immunohistochemistry and for cardiomyocyte cell death in H&E-stained sections. Enteroviruses and adenoviruses were searched for using PCR technology. The means of lymphocytes, macrophages, and necrotic cardiomyocytes were not statistically different in SIDS and suffocation cases. Enterovirus, not otherwise specified, was detected in one suffocation case and was the only virus detected in the three groups. Very mild myocardial lymphocyte and macrophage infiltration and scattered necrotic cardiomyocytes in SIDS are not pathologic, but may occur after the developing heart is exposed to environmental pathogens, including viruses.

Although advice from healthcare professionals may influence parental infant placement choice to reduce sudden infant death syndrome risk, literature on nursery staff infant placement behaviors and the degree to which they influence maternal infant sleep positioning is limited. To assess newborn placement practices of the mother and nursery staff and their interrelationship in the hospital setting. A cross-sectional survey-based study was conducted among hospital newborn nursery staff (n = 96) and mothers of newborns (n = 579) at eight perinatal hospitals in Orange County, California. Although a majority of sampled nursery staff (72%) identified the supine position as the placement that most lowers sudden infant death syndrome risk, only 30% reported most often placing infants to sleep in that position, with most staff (91%) citing fear of aspiration as the motivation for supine position avoidance. Only 34% of staff reported advising exclusive supine infant positioning to mothers. Approximately 36% of mothers reported using supine infant placement exclusively. Maternal infant placement choice varied by both the advice (p <.01) and the placement modeling (p <.01) provided by staff, with the highest proportion of usual supine infant placement found among mothers who reported receiving both. A mother's race/ethnicity also affected the reception of exclusive supine placement recommendations (p <.01). Exclusive supine infant placement appears to be underused by both nursery staff and mothers of newborn infants. Culturally grounded educational intervention with nursery staff regarding infant positioning and placement in the hospital setting is indicated.

2016-01-01

Study Objectives: To examine the association between sleep apnea and pregnancy outcomes in a large population-based cohort. Methods: Population-based cohort study using linked birth and hospital records was conducted in New South Wales, Australia. Participants were all women who gave birth from 2002 to 2012 (n = 636,227). Sleep apnea in the year before pregnancy or during pregnancy was identified from hospital records. Outcomes of interest were gestational diabetes, pregnancy hypertension, planned delivery, caesarean section, preterm birth, perinatal death, 5-minute Apgar score, admission to neonatal intensive care or special care nursery, and infant size for gestational age. Maternal outcomes were identified using a combination of hospital and birth records. Infant outcomes came from the birth record. Modified Poisson regression models were used to examine associations between sleep apnea and each outcome taking into account maternal age, country of birth, socioeconomic disadvantage, smoking, obesity, parity, pre-existing diabetes and hypertension. Results: Sleep apnea was significantly associated with pregnancy hypertension (adjusted RR 1.43; 95% CI 1.18–1.73), planned delivery (1.15; 1.07–1.23), preterm birth (1.50; 1.21–1.84), 5-minute Apgar < 7 (1.60; 1.07–2.38), admission to neonatal intensive care/special care nursery (1.26; 1.11–1.44), large-for-gestational-age infants (1.27; 1.04–1.55) but not with gestational diabetes (1.09; 0.82–1.46), caesarean section (1.06; 0.96–1.17), perinatal death (1.73; 0.92–3.25), or small-for-gestational-age infants (0.81; 0.61–1.08). Conclusions: Sleep apnea is associated with higher rates of obstetric complications and intervention, as well as preterm delivery. Future research should examine if these are independent of obstetric history. Citation: Bin YS, Cistulli PA, Ford JB.

Although sleep disturbances in infants and toddlers are common, there is no suitable validated tool in Spanish to evaluate sleep disorders. The Brief Infant Sleep Questionnaire (BISQ) is a well-established multidimensional questionnaire widely used internationally. To adapt the BISQ questionnaire to Spanish and analyse its reliability and validity. To explore its feasibility, both in the clinical context, and in epidemiological research. Participants were parents of children between 3 and 30 months of age. The adaptation to Spanish (BISQ-E) was achieved by using both back translation and consensus, following the international guidelines.Reliability was determined by means of test-retest and measurement of agreement (Kappa value) between 2forms of administration of the questionnaire (self-administration and clinical interview). Construct validity was established by analysing its correlation with a sleep diary. A total of 87 families/children participated. The test-retest reliability undertaken in 60 subjects was excellent; r = 0.848 (P<0.001). The kappa value was 0.939 (95% CI: 0.858-1.00, P<0.001).The agreement between BISQ-E and the sleep diary was analysed in 27 families/children, with statistically significant values being obtained for the following variables: bedtime (r = 0.731), hours of night sleep (r = 0.726), hours of daytime sleep (r = 0.867), and number of nocturnal awakenings (r = 0.888) (P < 0.001). The Spanish adaptation of the BISQ shows overall adequate validity and reliability for the evaluation of sleep in infants and pre-school children. Its use as a clinical tool, or for clinical-epidemiological research studies, is feasible. Copyright © 2017. Publicado por Elsevier España, S.L.U.

Buprenorphine has been available in Australia since 2000 as an alternative pharmacotherapy to methadone for the treatment of opioid dependence. However, there is little information in the literature regarding the effect of buprenorphine on the wellbeing of infants exposed to buprenorphine via breast milk, following discharge from hospital. The aim of the present study was to examine the wellbeing of infants exposed to buprenorphine via breast milk up to 4 weeks postnatally. Approximately 4 weeks after birth, information on the feeding and sleeping patterns, skin color, infant elimination patterns and hydration, and Neonatal Abstinence Scores of infants (n = 7) exposed to buprenorphine via breast milk was collected via both observation and documentation. Infants were progressing well, with normal sleep patterns and skin color, and 2 mothers had minor concerns regarding infant elimination patterns. Four infants were exclusively breastfed and 3 were receiving a supplement, with a range of 260 to 700 mL of formula over 24 hours. The sleep patterns following feeding ranged from 1.55 to 3.33 hours, with a median of 2.12 hours. No adverse effects were detected in infants exposed to buprenorphine via breast milk up to 4 weeks postnatally. Further research using larger samples to assess possible developmental effects over longer periods of time is required.

Sleep characteristics of young children in Japan: internet study and comparison with other Asian countries.

2011-10-01

A recent international Internet-based study of young children (birth to 36 months) found that total sleep duration in Japan was the shortest among 17 countries/regions. The present study compared features of children's sleep in Japan relative to those in other Asian countries/regions. Parents of 872 infants and toddlers in Japan (48.6% boys), and parents of 20 455 infants and toddlers in 11 other Asian countries/regions (48.1% boys; China, Hong Kong, India, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan, Thailand, and Vietnam) completed an Internet-based expanded version of the Brief Infant Sleep Questionnaire. Young children in Japan exhibited significantly fewer nocturnal wakings and shorter daytime sleep in comparison with other Asian countries/regions. Although the former finding was apparent in all age groups, the reduced duration of daytime sleep in Japan was not present until after 3 months of age. Interestingly, sleep problems were reported by significantly fewer parents in Japan compared with those in other Asian countries/regions, although parents in Japan reported significantly more difficulty at bedtime. The short sleep duration of young children in Japan is largely due to a relatively short duration of daytime sleep. Significant differences in sleep characteristics in Japan relative to other Asian regions were found primarily after 3 months of age. Future studies should further explore the underlying causes and the potential impacts of these sleep differences. © 2011 The Authors. Pediatrics International © 2011 Japan Pediatric Society.

The Visual Scoring of Sleep in Infants 0 to 2 Months of Age.

Grigg-Damberger, Madeleine M

2016-03-01

In March 2014, the American Academy of Sleep Medicine (AASM) Board of Directors requested the Scoring Manual Editorial Board develop rules, terminology, and technical specifications for scoring sleep/wake states in full-term infants from birth to 2 mo of age, cognizant of the 1971 Anders, Emde, and Parmelee Manual for Scoring Sleep in Newborns. On July 1, 2015, the AASM published rules for scoring sleep in infants, ages 0-2 mo. This evidence-based review summarizes the background information provided to the Scoring Manual Editorial Board to write these rules. The Anders Manual only provided criteria for coding physiological and behavioral state characteristics in polysomnograms (PSG) of infants, leaving specific sleep scoring criteria to the individual investigator. Other infant scoring criteria have been published, none widely accepted or used. The AASM Scoring Manual infant scoring criteria incorporate modern concepts, digital PSG recording techniques, practicalities, and compromises. Important tenets are: (1) sleep/wake should be scored in 30-sec epochs as either wakefulness (W), rapid eye movement, REM (R), nonrapid eye movement, NREM (N) and transitional (T) sleep; (2) an electroencephalographic (EEG) montage that permits adequate display of young infant EEG is: F3-M2, F4-M1, C3-M2, C4-M1, O1-M2, O2-M1; additionally, recording C3-Cz, Cz-C4 help detect early and asynchronous sleep spindles; (3) sleep onsets are more often R sleep until 2-3 mo postterm; (4) drowsiness is best characterized by visual observation (supplemented by later video review); (5) wide open eyes is the most crucial determinant of W; (6) regularity (or irregularity) of respiration is the single most useful PSG characteristic for scoring sleep stages at this age; (7) trace alternant (TA) is the only relatively distinctive EEG pattern, characteristic of N sleep, and usually disappears by 1 mo postterm replaced by high voltage slow (HVS); (8) sleep spindles first appear 44-48 w conceptional age (CA) and when present prompt scoring N; (9) score EEG activity in an epoch as "continuous" or "discontinuous" for inter-scorer reliability; (10) score R if four or more of the following conditions are present, including irregular respiration and rapid eye movement(s): (a) low chin EMG (for the majority of the epoch); (b) eyes closed with at least one rapid eye movement (concurrent with low chin tone); (c) irregular respiration; (d) mouthing, sucking, twitches, or brief head movements; and (e) EEG exhibits a continuous pattern without sleep spindles; (11) because rapid eye movements may not be seen on every page, epochs following an epoch of definite R in the absence of rapid eye movements may be scored if the EEG is continuous without TA or sleep spindles, chin muscle tone low for the majority of the epoch; and there is no intervening arousal; (12) Score N if four or more of the following conditions are present, including regular respiration, for the majority of the epoch: (a) eyes are closed with no eye movements; (b) chin EMG tone present; (c) regular respiration; and (d) EEG patterns of either TA, HVS, or sleep spindles are present; and (13) score T sleep if an epoch contains two or more discordant PSG state characteristics (either three NREM and two REM characteristics or two NREM and three REM characteristics). These criteria for ages 0-2 mo represent far more than baby steps. Like all the other AASM Manual rules and specifications none are fixed in stone, all open for debate, discussion and revision with the fundamental goal to provide standards for comparison of methods and results.

Preterm infants undergo stress owing to essential treatments and exposure to the extrauterine environment in neonatal intensive care units. The aim of this study was to enable preterm infants to maintain adequate positioning with a newly developed swaddling clothing, in order to improve low muscle tone and sleep quality, and to confirm the safety of the clothing. This prospective clinical trial included an intervention group (preterm infants wearing bag-shaped clothing, allowing only exposure of the head, n=27), and a control group (preterm infants managed only with conventional swaddling, n=12). We used the Dubowitz method to analyze behavior, recorded the frequency of vomiting and apnea in both groups, and assessed the sleep state in the intervention group. Muscle tone and total score for the Dubowitz method significantly improved in the intervention group, compared with those in the control group. We evaluated the sleep state before and after the introduction of the device in the intervention group, and State 1 increased from 53.5% to 69.2% after introduction. No significant difference was seen in the frequency of vomiting and apnea between the groups. The new swaddling clothing with enhanced stretch capacity improved the muscle tone and increased sleep time by decreasing the state level of preterm infants. This is an effective tool to assist in infant development in neonatal intensive care units. Copyright © 2017 Elsevier B.V. All rights reserved.

Secure parent-child relationships are implicated in children's self-regulation, including the ability to self-soothe at bedtime. Sleep, in turn, may serve as a pathway linking attachment security with subsequent emotional and behavioral problems in children. We used path analysis to examine the direct relationship between attachment security and maternal reports of sleep problems during toddlerhood and the degree to which sleep serves as a pathway linking attachment with subsequent teacher-reported emotional and behavioral problems. We also examined infant negative emotionality as a vulnerability factor that may potentiate attachment-sleep-adjustment outcomes. Data were drawn from 776 mother-infant dyads participating in the National Institute of Child and Human Development Study of Early Child Care. After statistically adjusting for mother and child characteristics, including child sleep and emotional and behavioral problems at 24 months, we found no evidence for a statistically significant direct path between attachment security and sleep problems at 36 months; however, there was a direct relationship between sleep problems at 36 months and internalizing problems at 54 months. Path models that examined the moderating influence of infant negative emotionality demonstrated significant direct relationships between attachment security and toddler sleep problems and between sleep problems and subsequent emotional and behavioral problems, but only among children characterized by high negative emotionality at 6 months. In addition, among this subset, there was a significant indirect path between attachment and internalizing problems through sleep problems. These longitudinal findings implicate sleep as one critical pathway linking attachment security with adjustment difficulties, particularly among temperamentally vulnerable children.

To characterize cross-cultural sleep patterns and sleep problems in a large sample of children ages birth to 36 months in multiple predominantly-Asian (P-A) and predominantly-Caucasian (P-C) countries. Parents of 29,287 infants and toddlers (predominantly-Asian countries/regions: China, Hong Kong, India, Indonesia, Korea, Japan, Malaysia, Philippines, Singapore, Taiwan, Thailand, Vietnam; predominantly-Caucasian countries: Australia, Canada, New Zealand, United Kingdom, United States) completed an internet-based expanded version of the Brief Infant Sleep Questionnaire. Overall, children from P-A countries had significantly later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to both bed-share and room-share than children from P-C countries, p<.001. Bedtimes ranged from 19:27 (New Zealand) to 22:17 (Hong Kong) and total sleep time from 11.6 (Japan) to 13.3 (New Zealand) hours, p<.0001. There were limited differences in daytime sleep. Bed-sharing with parents ranged from 5.8% in New Zealand to 83.2% in Vietnam. There was also a wide range in the percentage of parents who perceived that their child had a sleep problem (11% in Thailand to 76% in China). Overall, children from predominantly-Asian countries had significantly later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to room-share than children from predominantly-Caucasian countries/regions. These results indicate substantial differences in sleep patterns in young children across culturally diverse countries/regions. Further studies are needed to understand the basis for and impact of these interesting differences. Copyright 2010 Elsevier B.V. All rights reserved.

Teti, Douglas M; Crosby, Brian

2012-01-01

Mechanisms were examined to clarify relations between maternal depressive symptoms, dysfunctional cognitions, and infant night waking among 45 infants (1-24 months) and their mothers. A mother-driven mediational model was tested in which maternal depressive symptoms and dysfunctional cognitions about infant sleep predicted infant night waking via their impact on mothers' bedtime and nighttime behavior with infants (from video). Two infant-driven mediational models were also examined, in which infant night waking predicted maternal depressive symptoms, or dysfunctional cognitions, via their impact on nighttime maternal behavior. Stronger support for the mother-driven model was obtained, which was further supported by qualitative observations from video-recordings. This study provides important insights about maternal depression's effects on nighttime parenting, and how such parenting affects infant sleep. © 2012 The Authors.

2010-11-30

This study documented the effect of position on cardioventilatory coupling (CVC), the triggering of inspiratory onset by a preceding heartbeat, in infants. Cardiorespiratory signals and corresponding oxygen saturation (SpO(2)) were downloaded from Quiet Sleep (QS) and Active Sleep (AS) in prone and supine from preterm (PT) and term (T) infants. Inspiratory onsets (I) and timing of the corresponding ECG R wave were determined and R-R and R-I intervals calculated. The RI(-1) interval (time between inspiration and the preceding R wave) dispersion was measured using proportional Shannon Entropy of the RI(-1) interval (SH(α)), to provide a quantitative measure of CVC. CVC was more frequently seen in QS in PT (p=0.002) and T (p=0.02) infants but not influenced by position (p=0.71, p=0.46). CVC correlated with SpO(2) in PT (r=-0.230, p=0.03) but not T infants (r=0.085, p=0.34). These data imply an augmentation of cardiac influence on ventilatory rhythm in infants in QS. In preterm infants CVC may have a role in supporting oxygenation. Copyright © 2010 Elsevier B.V. All rights reserved.

We have compared 430 healthy Swedish infants born between 1991 and 1995 with 599 healthy, six months old infants born in 2002, regarding the prevalence of risk factors for SIDS. Following the introduction of the campaign to reduce the risk of SIDS in Sweden in 1992, we could see a decrease in prone sleeping from 32% to 7% together with an increase in supine sleeping from 35% to 44%. Maternal smoking during pregnancy has gone down from 24% to 10%. The prevalence of breast feeding, already high in Sweden in the 90s, was largely unchanged, 69% at six months of age in 2002. This comparison shows that parents of small infants have accepted the advice on ways to reduce the risk of SIDS, and that information given at infant welfare clinics is still effective ten years later. Further improvements are possible by changing the side sleeping position to supine, and by decreasing tobacco smoking among pregnant mothers.

Sleep and Neurofunctions Throughout Child Development: Lasting Effects of Early Iron Deficiency

PubMed Central

Peirano, Patricio D.; Algarín, Cecilia R.; Chamorro, Rodrigo; Garrido, Marcelo I.; Lozoff, Betsy

2013-01-01

Iron-deficiency anemia (IDA) continues to be the most common single nutrient deficiency in the world. Infants are at particular risk due to rapid growth and limited dietary sources of iron. An estimated 20–25% of the world’s infants have IDA, with at least as many having iron deficiency without anemia. High prevalence is found primarily in developing countries, but also among poor, minority, and immigrant groups in developed ones. Infants with IDA test lower in mental and motor development assessments and show affective differences. After iron therapy, follow-up studies point to long-lasting differences in several domains. Neurofunctional studies showed slower neural transmission in the auditory system despite 1 year of iron therapy in IDA infants; they still had slower transmission in both the auditory and visual systems at preschool age. Different motor activity patterning in all sleep-waking states and several differences in sleep states organization were reported. Persistant sleep and neurofunctional effects could contribute to reduced potential for optimal behavioral and cognitive outcomes in children with a history of IDA. PMID:19214058

Risky Behaviors of Mothers with Infants on Sudden Infant Death Syndrome in Turkey.

PubMed

Erdoğan, Çiğdem; Turan, Türkan

Sudden infant death syndrome is the most common cause of death during the post-neonatal period. Factors such as sleeping position, bed sharing, pillow use, smoking during pregnancy and the breastfeeding period constitute risk factors for sudden infant death syndrome. This study aims to identify the risky behaviors of mothers with infants that may put their children at risk for sudden infant death syndrome. This is a cross-sectional, descriptive study. Data were collected using a questionnaire that was developed by the researchers. The questionnaire was filled out by 456 mothers who applied to the family health center between October 2014 and January 2015. The greatest risk factor is the infant's sleeping position. A total of 77.9% of the mothers put their babies in bed in a non-supine position; 65.8% used a pillow when they put their babies in bed, 52.9% used a soft mattress, and 28.5% shared their beds with their babies. Prone sleeping was more likely to occur when smoke was present in the home or a pillow was used. Nurses should notify families of the risky behaviors that can cause sudden infant death syndrome and plan appropriate nursing care. Copyright © 2017 Elsevier Inc. All rights reserved.

Why is there an increased risk for sudden infant death in prone sleeping? Fear paralysis and atrial stretch reflexes implicated?

PubMed

Kaada, B

1994-05-01

A number of recent reports have indicated a higher risk of sudden infant death syndrome (SIDS) in the prone sleeping position, compared with the supine position. However, the biological mechanisms for this increased risk have not been established. For this report, two biological explanations are proposed, each of which may be influenced by altered sleeping position in such a way that they may create conditions for increased triggering of SIDS.

Prenatal Nicotine Exposure Disrupts Infant Neural Markers of Orienting.

PubMed

King, Erin; Campbell, Alana; Belger, Aysenil; Grewen, Karen

2018-06-07

Prenatal nicotine exposure (PNE) from maternal cigarette smoking is linked to developmental deficits, including impaired auditory processing, language, generalized intelligence, attention, and sleep. Fetal brain undergoes massive growth, organization, and connectivity during gestation, making it particularly vulnerable to neurotoxic insult. Nicotine binds to nicotinic acetylcholine receptors, which are extensively involved in growth, connectivity, and function of developing neural circuitry and neurotransmitter systems. Thus, PNE may have long-term impact on neurobehavioral development. The purpose of this study was to compare the auditory K-complex, an event-related potential reflective of auditory gating, sleep preservation and memory consolidation during sleep, in infants with and without PNE and to relate these neural correlates to neurobehavioral development. We compared brain responses to an auditory paired-click paradigm in 3- to 5-month-old infants during Stage 2 sleep, when the K-complex is best observed. We measured component amplitude and delta activity during the K-complex. Infants with PNE demonstrated significantly smaller amplitude of the N550 component and reduced delta-band power within elicited K-complexes compared to nonexposed infants and also were less likely to orient with a head turn to a novel auditory stimulus (bell ring) when awake. PNE may impair auditory sensory gating, which may contribute to disrupted sleep and to reduced auditory discrimination and learning, attention re-orienting, and/or arousal during wakefulness reported in other studies. Links between PNE and reduced K-complex amplitude and delta power may represent altered cholinergic and GABAergic synaptic programming and possibly reflect early neural bases for PNE-linked disruptions in sleep quality and auditory processing. These may pose significant disadvantage for language acquisition, attention, and social interaction necessary for academic and social success.

To investigate mothers' knowledge of reducing the risks for sudden infant death syndrome (SIDS) and attitudes towards safer sleep practices. A cross-sectional survey was carried out in deprived areas of Bristol, UK. Recruitment took place in 2014 at local health visitor-led baby clinics. Of 432 mothers approached, 400 (93%) completed the face-to-face survey. Participants with infants at 'higher' risk of SIDS (using an algorithm based on a previous observational study) were compared with those at 'lower' risk. The survey asked participants to recall three SIDS risk reduction strategies (unprompted), and scored responses to 14 SIDS risk-related infant sleep scenarios (prompted). Overall, 48/400 (12%) mothers were classified as higher risk. Mothers in the higher risk group were less likely to breast feed (multivariate OR=3.59(95% CI 1.46 to 8.86)), less likely to be able to cite two or more unprompted correct SIDS risk reduction strategies (multivariate OR=2.05(95% CI 1.02 to 4.13)) and scored lower on prompted safer sleep scenarios overall.Notably, only 206/400 (52%) of all mothers surveyed (33% in the higher risk group) from these deprived areas in Bristol identified infant sleep position as a risk reduction strategy for SIDS, despite 25 years of campaigns. Mothers in the higher risk group were disadvantaged when it came to some aspects of knowledge of SIDS risk reduction and attitudes to safer sleep. The initial 'Back-to Sleep' message that dramatically reduced these deaths a generation ago needs more effective promotion for today's generation of mothers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The Alberta Infant Motor Scales (AIMS) is a reliable and valid assessment tool to evaluate the motor performance from birth to independent walking. This study aimed to determine whether the Canadian reference values on the AIMS from 1990-1992 are still useful tor Flemish infants, assessed in 2007-2010. Additionally, the association between motor performance and sleep and play positioning will be determined. A total of 270 Flemish infants between 0 and 18 months, recruited by formal day care services, were assessed with the AIMS by four trained physiotherapists. Information about sleep and play positioning was collected by mean of a questionnaire. Flemish infants perform significantly lower on the AIMS compared with the reference values (P < 0.001). Especially, infants from the age groups of 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and of 15 months showed significantly lower scores. From the information collected by parental questionnaires, the lower motor scores seem to be related to the sleep position, the amount of play time in prone, in supine and in a sitting device. Infants who are exposed often to frequently to prone while awake showed a significant higher motor performance than infants who are exposed less to prone (<6 m: P = 0.002; >6 m: P = 0.013). Infants who are placed often to frequently in a sitting device in the first 6 months of life (P = 0.010) and in supine after 6 months (P = 0.001) performed significantly lower than those who are placed less in it. Flemish infants recruited by formal day care services, show significantly lower motor scores than the Canadian norm population. New reference values should be established for the AIMS for accurate identification of infants at risk. Prevention of sudden infant death syndrome by promoting supine sleep position should go together with promotion of tummy time when awake and avoiding to spent too much time in sitting devices when awake. © 2012 Blackwell Publishing Ltd.

Developing robust recurrence plot analysis techniques for investigating infant respiratory patterns.

Terrill, Philip I; Wilson, Stephen; Suresh, Sadasivam; Cooper, David M

2007-01-01

Recurrence plot analysis is a useful non-linear analysis tool. There are still no well formalised procedures for carrying out this analysis on measured physiological data, and systemising analysis is often difficult. In this paper, the recurrence based embedding is compared to radius based embedding by studying a logistic attractor and measured breathing data collected from sleeping human infants. Recurrence based embedding appears to be a more robust method of carrying out a recurrence analysis when attractor size is likely to be different between datasets. In the infant breathing data, the radius measure calculated at a fixed recurrence, scaled by average respiratory period, allows the accurate discrimination of active sleep from quiet sleep states (AUC=0.975, Sn=098, Sp=0.94).

2009-08-01

Low birth weight (LBW) infants sleeping prone are known to exhibit many physiological differences from those sleeping supine, including lower energy expenditure (heat production) and higher surface temperature. This apparent increase in heat storage suggests that heat loss may be inhibited in the prone position which, in turn, might influence cardiorespiratory activity. To determine the effects of body position (prone vs. supine) on absolute surface temperature profile (heat storage), central-peripheral (C-P) thermal gradients (vasomotor response), cardiorespiratory activity and metabolic gas exchange in growing LBW infants. Six-hour continuous recordings of absolute surface temperature profiles, cardiorespiratory activity and O2 and CO2 exchange, along with minute-to-minute assessment of behavioral sleep states were performed in 32 healthy growing LBW infants (birth weight 805-1590 g, gestational age 26-35 weeks and postconceptional age at study 33-38 weeks). Each infant was randomly assigned to the prone or supine position for the first 3 h of the study and then reversed for the second 3 h. Surface temperatures were recorded from 4 sites (forehead, flank, forearm and leg) and averaged each minute. Central (forehead and flank)-to-peripheral (forearm and leg) and forehead-to-environment (H-E) thermal gradients were calculated from the surface temperatures. Corresponding sleep states were aligned with minute averages obtained from the temperature and cardiorespiratory measurements. Data were then sorted for prone and supine positions during quiet (QS) and active sleep (AS) and compared using paired t-tests. In the prone position during both AS and QS, infants had higher forehead, flank, forearm and leg surface temperatures, narrower C-P gradients, higher heart rates and respiratory frequency, and lower heart rate and respiratory variability. Despite similar environmental temperatures, the H-E gradient was higher in the prone position. In the prone position infants demonstrated lower O2 consumption and CO2 production and a higher respiratory quotient. Despite thermoregulatory adjustments in cardiorespiratory function, infants sleeping prone have relatively higher body temperature. The cardiorespiratory responses to this modest increase in temperature indicate that thermal and metabolic control of cardiac and respiratory pumps seem to work in opposition. The consequences of any attendant changes in blood gas activity (e.g. hypocapnia and/or increased mixed venous oxygen concentration) due to this override of metabolic control remains speculative.

Real Time Apnoea Monitoring of Children Using the Microsoft Kinect Sensor: A Pilot Study.

Al-Naji, Ali; Gibson, Kim; Lee, Sang-Heon; Chahl, Javaan

2017-02-03

The objective of this study was to design a non-invasive system for the observation of respiratory rates and detection of apnoea using analysis of real time image sequences captured in any given sleep position and under any light conditions (even in dark environments). A Microsoft Kinect sensor was used to visualize the variations in the thorax and abdomen from the respiratory rhythm. These variations were magnified, analyzed and detected at a distance of 2.5 m from the subject. A modified motion magnification system and frame subtraction technique were used to identify breathing movements by detecting rapid motion areas in the magnified frame sequences. The experimental results on a set of video data from five subjects (3 h for each subject) showed that our monitoring system can accurately measure respiratory rate and therefore detect apnoea in infants and young children. The proposed system is feasible, accurate, safe and low computational complexity, making it an efficient alternative for non-contact home sleep monitoring systems and advancing health care applications.

Infant arousal scoring based on the Atlas Task Force definition of transient EEG arousal was evaluated to determine (1). whether transient arousals can be identified and assessed reliably in infants and (2). whether arousal and no-arousal epochs scored previously by trained raters can be validated reliably by independent sleep experts. Phase I for inter- and intrarater reliability scoring was based on two datasets of sleep epochs selected randomly from nocturnal polysomnograms of healthy full-term, preterm, idiopathic apparent life-threatening event cases, and siblings of Sudden Infant Death Syndrome infants of 35 to 64 weeks postconceptional age. After training, test set 1 reliability was assessed and discrepancies identified. After retraining, test set 2 was scored by the same raters to determine interrater reliability. Later, three raters from the trained group rescored test set 2 to assess inter- and intrarater reliabilities. Interrater and intrarater reliability kappa's, with 95% confidence intervals, ranged from substantial to almost perfect levels of agreement. Interrater reliabilities for spontaneous arousals were initially moderate and then substantial. During the validation phase, 315 previously scored epochs were presented to four sleep experts to rate as containing arousal or no-arousal events. Interrater expert agreements were diverse and considered as noninterpretable. Concordance in sleep experts' agreements, based on identification of the previously sampled arousal and no-arousal epochs, was used as a secondary evaluative technique. Results showed agreement by two or more experts on 86% of the Collaborative Home Infant Monitoring Evaluation Study arousal scored events. Conversely, only 1% of the Collaborative Home Infant Monitoring Evaluation Study-scored no-arousal epochs were rated as an arousal. In summary, this study presents an empirically tested model with procedures and criteria for attaining improved reliability in transient EEG arousal assessments in infants using the modified Atlas Task Force standards. With training based on specific criteria, substantial inter- and intrarater agreement in identifying infant arousals was demonstrated. Corroborative validation results were too disparate for meaningful interpretation. Alternate evaluation based on concordance agreements supports reliance on infant EEG criteria for assessment. Results mandate additional confirmatory validation studies with specific training on infant EEG arousal assessment criteria.

A pilot randomised controlled trial was conducted with postpartum mothers to assess the feasibility and impact of note-taking during newborn teaching. Controls received standard teaching; the intervention group received pen and paper to take notes. Subjects were called 2 days post-discharge to assess infant sleep position, breastfeeding, car seat use, satisfaction and information recall. 126 mothers were randomised. There was a consistent trend that intervention subjects were more likely to report infant supine sleep position (88% vs 78%, relative risks (RR) 1.13; 95% CI 0.95 to 1.34), breastfeeding (96% vs 86%, RR 1.11; 95% CI 0.99 to 1.25) and correct car seat use (98% vs 87%, RR 1.12; 95% CI 1.00 to 1.25). Satisfaction and information recall did not differ. Among first-time mothers, intervention subjects were significantly more likely to report infant supine sleep position (95% vs 65%, RR 1.46; 95% CI 1.06 to 2.00). Maternal note-taking is feasible and potentially efficacious in promoting desirable infant care.

2015-01-01

The aim of this study was to assess the primary concerns of parents/caregivers regarding their young child's sleep. A total of 1,287 consecutive sleep-related questions were analyzed from submissions to an Ask the Expert section of a publicly available iPhone-based application for sleep in young children. Questions regarding infants were most likely to be submitted (53.9%), followed by newborns (23.76%) and toddlers (17.8%), with an average age of 10.94 months. The primary concerns regarded night wakings, sleep schedules, and bedtime problems, accounting for almost 85% of all questions. Results align with common concerns noted in epidemiological studies. Understanding the types of concerns for which parents seek advice is beneficial in the continued development of resources for caregivers.

Aim To provide descriptive figures for infant distress and associated parenting at night in normal London home environments during the first three months of age. Most western infants develop long night-time sleep periods by four months of age. However, 30% of infants in many countries sleep for short periods and cry out on waking in the night: the most common type of infant sleep behaviour problem. Preventive interventions may help families and improve services. There is evidence that 'limit-setting' parenting, which is common in western cultures, supports the development of settled infant night-time behaviour. However, a recent review has challenged this and argued that this form of parenting risks distressing infants. This study describes limit-setting parenting as practiced in London, compares it with 'infant-cued' parenting and measures the associated infant distress. Longitudinal infrared video, diary and questionnaire observations comparing a General-Community (n=101) group and subgroups with a Bed-Sharing (n=19) group on measures of infant and parenting behaviours at night. Findings General-Community parents took longer to detect and respond to infant waking and signalling, and to begin feeding, compared with the highly infant-cued care provided by Bed-Sharing parents. The average latency in General-Community parents' responding to infant night-time waking was 3.5 min, during which infants fuss/cried for around 1 min. Compared with Bed-Sharing parenting, General-Community parenting was associated with increased infant distress of around 30 min/night at two weeks, reducing to 12 min/night by three months of age. However, differences in infant distress between General-Community subgroups adopting limit-setting versus infant-cued parenting were not large or statistically significant at any age. The figures provide descriptive evidence about limit-setting parenting which may counter some doubts about this form of parenting and help parents and professionals to make choices.

A Case Study of the Environmental Experience of a Hospitalized Newborn Infant With Complex Congenital Heart Disease.

PubMed

Daniels, Jacki M; Harrison, Tondi M

2016-01-01

Infants with complex congenital heart disease are at high risk for developmental delays. Although the etiology of these delays is multifactorial, the physical environment may be a contributory factor. Extensive studies have been conducted in neonatal intensive care units measuring environmental influences on development, resulting in policy and practice changes. Cardiothoracic intensive care units and cardiac step-down units are new environments in which newborns with heart disease receive care. No environmental studies have been conducted in units caring for newborn infants recovering from cardiac surgery. The aim of this study is to examine the environmental experience of a newborn infant with heart disease after surgical intervention within the first month of life. Measurements of illumination, sound levels, and sleep were recorded on 1 infant for 2 consecutive postoperative days in the cardiothoracic intensive care unit and 2 consecutive days in the step-down unit. Although average daily noise exposure remained below recommended guidelines on 3 of 4 days, the infant experienced intermittent periods of excessive noise (≥55 dBA) during 59 of 87 hours and 110 episodes of acute noise events greater than 70 dBA. Average daily light exposure was below the recommended guidelines. However, light levels were more than twice the recommended levels at multiple points daily. For each of the 4 observation days, the infant experienced 66 to 102 awakenings during sleep, and sleep durations were less than 30 minutes 90% of the time. This study provides the first report of potential environmental stressors in newborn infants cared for in cardiac specialty units. Excessive levels of light and noise as well as frequent interruptions for medical and nursing care may contribute to disorganized sleep and increased patient distress and may impact subsequent neurodevelopment. Studies are needed to identify potentially adverse aspects of the intensive caregiving environment for newborn infants who have undergone cardiac surgery.

Transformative unlearning: safety, discernment and communities of learning.

Macdonald, Geraldine

2002-09-01

This paper aims to stimulate awareness about the intellectual and emotional work of 'unlearning' in knowledge workers in the emerging learning age. The importance of providing a safe space for dialogue to promote transformative learning, through building 'communities of learning', is highlighted. Unlearning is conceptualized within a transformative education paradigm, one whose primary orientation is discernment, a personal growth process involving the activities of receptivity, recognition and grieving. The author utilizes the metaphor of an unfolding spiral path to explore her experience of needing to 'unlearn' a trusted nursing practice prior to 'learning' new best caring practices related to infant sleep positions. Macro and micro approaches to facilitating unlearning in organizations, in learners and in nurses are suggested.

2009-12-01

The aim of the present study was to examine the effects of breast-feeding method (on only one or on two sides in a single feeding session) on growth, sleep duration and sucking period, and stool frequency. Exclusively breast-fed healthy infants, aged 1-6 months, were included in the study during child health follow-up visits. Mothers were given a questionnaire on sleep duration, sucking periods, and stool frequencies of their infants. The height-for-age and weight-for-age z scores were significantly higher in infants breast-fed from one side during a single session than from both sides (P= 0.002, P < 0.001; respectively). Infants sucking on only one breast in a breast-feeding session defecated significantly less at night (P= 0.005), their maximum sucking periods at night were shorter (P= 0.049). Breast-feeding at one side only during a single breast-feeding session increases growth, decreases stool frequency and the maximum sucking period at night and does not influence the overall sleep pattern.

To identify caregiving-related sleep problems and their relationship to mental health and daytime function in female Veterans. Female Veterans (N = 1,477) from cross-sectional, nationwide, postal survey data. The survey respondent characteristics included demographics, comorbidity, physical activity, health, use of sleep medications, and history of sleep apnea. They self-identified caregiving- related sleep problems (i.e., those who had trouble sleeping because of caring for a sick adult, an infant/child, or other respondents). Patient Health Questionnaire (PHQ-4) was used to assess mental health, and daytime function was measured using 11 items of International Classification of Sleep Disorders-2 (ICSD-2). Female Veterans with self-identified sleep problems due to caring for a sick adult (n = 59) experienced significantly more symptoms of depression and anxiety (p < 0.001) and impairment in daytime function (e.g., fatigue, daytime sleepiness, loss of concentration, p < 0.001) than those with self-identified sleep problems due to caring for an infant or child (n = 95) or all other respondents (n = 1,323) after controlling for the respondent characteristics. Healthcare providers should pay attention to assessing sleep characteristics of female Veterans with caregiving responsibilities, particularly those caregiving for a sick adult.

Postnatal Unit Bassinet Types When Rooming-In After Cesarean Birth: Implications for Breastfeeding and Infant Safety

PubMed Central

Tully, Kristin P.; Ball, Helen L.

2013-01-01

Background Postnatal unit rooming-in promotes breastfeeding. Previous research indicates that side-cars (three-sided bassinets that lock onto the maternal bed-frame) faciliate breastfeeding after vaginal birth more than stand-alone bassinets (standard rooming-in). No study has previously investigated side-car bassinet use after cesarean, despite the constraints on maternal-infant interactions that are inherent in recovery from this birth mode. Objective To test the effect of the side-car bassinet on postnatal unit breastfeeding frequency and other maternal-infant behaviors compared to a stand-alone bassinet following cesarean birth. Methods Participants were recruited and prenatally randomized to receive the side-car or stand-alone bassinet for their postnatal unit stay between January 2007 and March 2009 in Northeast England. Mother-infant interactions were filmed over the second postpartum night. Participants completed face-to-face interviews before and after filming. The main outcome measures were infant location, bassinet acceptability, and breastfeeding frequency. Other outcomes assessed were breastfeeding effort, maternal-infant contact, sleep states, midwife presence, and infant risk. Results Differences in breastfeeding frequency, maternal-infant sleep overlap, and midwife presence were not statistically significant. The 20 dyads allocated to side-car bassinets breastfed a median of 0.6 bouts/ hour compared to 0.4 bouts/hour for the 15 stand-alone bassinet dyads. Participants expressed overwhelming preference for the side-car bassinets. Bedsharing was equivalent between the groups, although the motivation for this practice may have differed. Infant handling was compromised with stand-alone bassinet use, including infants positioned on pillows while bedsharing with their sleeping mothers. Conclusions Women preferred the side-car but differences in breastfeeding frequency were not significant. More infant risks were observed with stand-alone bassinet use. PMID:22914755

The Effect of Sigh on Cardiorespiratory Synchronization in Healthy Sleeping Infants

PubMed Central

Nguyen, Chinh D.; Dakin, Carolyn; Yuill, Margaret; Crozier, Stuart; Wilson, Stephen

2012-01-01

Study Objectives: Sighs are thought to have a role in regulating breathing control. They may preceed a central apnea (sigh-CA) or a pause (sigh-P), particularly in quiet sleep. Recent techniques characterizing cardiorespiratory synchronization (CRS) provide sensitive measures of cardiorespiratory coupling, which is an important factor in breathing control. We speculated that the strength of CRS and direction of cardiorespiratory coupling (DC), would differ between sigh-P and sigh-CA; before and after a sigh; and with maturation. Design: Prospective study. CRS and DC were calculated from the respiratory signal and heart rate before and after sighs recorded during overnight polysomnography. Setting: Sleep laboratory. Participants: The data were selected from 15 subjects of a prospective cohort of 34 healthy infants at ages 2 weeks, 3 months and 6 months. Interventions: N/A. Measurements and results: Both CRS and respiratory modulation on heart rate (RMH) (negative DC index) were decreased around sigh-CA compared with sigh-P at all ages. Short-term CRS decreased after both sigh-P and sigh-CA in infants aged 2 weeks and 3 months. Long term CRS did not change before and after sigh-P or sigh-CA. CRS and RMH were increased at 3 months and 6 months compared to 2 weeks. Conclusions: A sigh was not found to be associated with apparent resetting of breathing control in healthy infants less than 6 months of age. Cardiorespiratory coupling appears to be a leading marker of changes in breathing control, preceding central apnea associated with a sigh. Citation: Nguyen CD; Dakin C; Yuill M; Crozier S; Wilson S.

To establish the occurrence of SIDS risk factors (including 'removable' ones) and the incidence of the ecg long QT interval (accepted as a risk factor) and their influence upon infants development and morbidity. A group of 98 infants from normal birth at term to the end of first year of life was observed. The data sources were as follows: 1) a questionnaire filled by mothers before discharge front maternity ward, 2) records of four consecutive medical examinations (including ecg records) performed on 3rd day and 3rd, 6th and 12th month of life. Chi-Square test and Fisher test were used. The most often identified risk factors were: prone sleeping position of infant (60.2%), environmental and maternal tobacco smoking (40.8%) and bed sharing practices (32.6%). A significant but transient signs of delay in psychomotor development (in motor zone) as well as more frequent respiratory tract infections in infants sleeping prone were noted. There were no deaths in the observed group neither cases of long QT interval. 1) the most frequently occurring SIDS risk factors are: environmental tobacco smoking, infant prone sleeping and bed sharing, 2) these inappropriate nursing practices and improper habits of adult family members known as a 'removable' SIDS risk factors have a bad effect on infant health and development, 3) identification of SIDS risk factors in an infant does not predict crib death.

Characterising non-linear dynamics in nocturnal breathing patterns of healthy infants using recurrence quantification analysis.

2013-05-01

Breathing dynamics vary between infant sleep states, and are likely to exhibit non-linear behaviour. This study applied the non-linear analytical tool recurrence quantification analysis (RQA) to 400 breath interval periods of REM and N-REM sleep, and then using an overlapping moving window. The RQA variables were different between sleep states, with REM radius 150% greater than N-REM radius, and REM laminarity 79% greater than N-REM laminarity. RQA allowed the observation of temporal variations in non-linear breathing dynamics across a night's sleep at 30s resolution, and provides a basis for quantifying changes in complex breathing dynamics with physiology and pathology.

The relationship between mismatch response and the acoustic change complex in normal hearing infants.

Uhler, Kristin M; Hunter, Sharon K; Tierney, Elyse; Gilley, Phillip M

2018-06-01

To examine the utility of the mismatch response (MMR) and acoustic change complex (ACC) for assessing speech discrimination in infants. Continuous EEG was recorded during sleep from 48 (24 male, 20 female) normally hearing aged 1.77 to -4.57 months in response to two auditory discrimination tasks. ACC was recorded in response to a three-vowel sequence (/i/-/a/-/i/). MMR was recorded in response to a standard vowel, /a/, (probability 85%), and to a deviant vowel, /i/, (probability of 15%). A priori comparisons included: age, sex, and sleep state. These were conducted separately for each of the three bandpass filter settings were compared (1-18, 1-30, and 1-40 Hz). A priori tests revealed no differences in MMR or ACC for age, sex, or sleep state for any of the three filter settings. ACC and MMR responses were prominently observed in all 44 sleeping infants (data from four infants were excluded). Significant differences observed for ACC were to the onset and offset of stimuli. However, neither group nor individual differences were observed to changes in speech stimuli in the ACC. MMR revealed two prominent peaks occurring at the stimulus onset and at the stimulus offset. Permutation t-tests revealed significant differences between the standard and deviant stimuli for both the onset and offset MMR peaks (p < 0.01). The 1-18 Hz filter setting revealed significant differences for all participants in the MMR paradigm. Both ACC and MMR responses were observed to auditory stimulation suggesting that infants perceive and process speech information even during sleep. Significant differences between the standard and deviant responses were observed in the MMR, but not ACC paradigm. These findings suggest that the MMR is sensitive to detecting auditory/speech discrimination processing. This paper identified that MMR can be used to identify discrimination in normal hearing infants. This suggests that MMR has potential for use in infants with hearing loss to validate hearing aid fittings. Copyright © 2018 International Federation of Clinical Neurophysiology.

Despite the success of safe sleep campaigns and the progress in understanding risk factors, the rate of reduction in the cases of sudden infant death syndrome has now slowed and it remains a leading cause of postneonatal mortality in many developed countries. Strategic action is needed to tackle this problem and it is now vital to identify how the sudden infant death research community may best target its efforts. The Global Action and Prioritization of Sudden Infant Death Project was an international consensus process that aimed to define and direct future research by investigating the priorities of expert and lay members of the sudden unexpected infant death (SUID) community across countries. The aim was to identify which areas of research should be prioritized to reduce the number of SUID deaths globally. Scientific researchers, clinicians, counselors, educators, and SUID parents from 25 countries took part across 2 online surveys to identify potential research priorities. Workshops subsequently took place in the United Kingdom, United States, and Australia to reach consensus and 10 priority areas for research were established. Three main themes among the priorities emerged: (1) a better understanding of mechanisms underlying SUID, (2) ensuring best practice in data collection, management and sharing, and (3) a better understanding of target populations and more effective communication of risk. SUID is a global problem and this project provides the international SUID community with a list of shared research priorities to more effectively work toward explaining and reducing the number of sudden infant deaths.

Abnormal blood pressure control is implicated in the sudden infant death syndrome (SIDS). However, no data exist on normal development of blood pressure control during infancy. This study assessed maturation of autonomic control of blood pressure and heart rate during sleep within the first 6 months of life. Term infants (n = 31) were studied longitudinally at 2-4 weeks, 2-3 months, and 5-6 months postnatal age. Infants underwent daytime polysomnography at each age studied. Blood pressure and heart rate were recorded during quiet (QS) and active (AS) sleep in undisturbed baseline and head-up tilt conditions. Autonomic control was assessed using spectral indices of blood pressure and heart rate variability (BPV and HRV) in ranges of low frequency (LF, reflecting sympathetic + parasympathetic activity) and high frequency (HF, parasympathetic activity), total power (LF+HF), and LF/HF ratio (sympathovagal balance). With increasing postnatal age and predominantly during QS, HRV-LF, HRV-HF, and HRV total power increased, while HRV-LF/HF decreased. BPV-LF/HF also decreased with postnatal age. All changes were evident in both baseline and head-up tilt conditions. BPV-LF and BPV total power during tilts were markedly reduced in QS versus AS at each age. In sleeping infants, sympathetic vascular modulation of the circulation decreases with age, while parasympathetic control of heart rate is strengthened. These normative data will aid in the early identification of conditions where autonomic function is impaired, such as in SIDS.

We tested whether mother-infant bed-sharing is associated with increased secure infant-mother attachment, a previously unexplored association. Frequency of bed-sharing and mothers' nighttime comforting measures at 2 months were assessed with questionnaires in 550 Caucasian mothers from a population-based cohort. Attachment security was assessed with the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978) at 14 months. When using a dichotomous variable, "never bed-sharing" (solitary sleepers) versus "any bed-sharing," the relative risk of being classified as insecurely attached for solitary-sleeping infants (vs. bed-sharers) was 1.21 (95% confidence interval: 1.05-1.40). In multivariate models, solitary sleeping was associated with greater odds of insecure attachment, adjusted odds ratio (OR): 1.50, 95% CI = 1.02-2.20) and, in particular, with greater odds of resistant attachment, adjusted OR = 1.74, 95% CI = 1.10-2.76); and with a lower attachment security score, β = -0.12, t(495) = -2.61, p = .009. However, we found no evidence of a dose-response association between bed-sharing and secure attachment when using a trichotomous bed-sharing variable based on frequency of bed-sharing. Our findings demonstrate some evidence that solitary sleeping is associated with insecure attachment. However, the lack of a dose-response association suggests that further experimental study is necessary before accepting common notions that sharing a bed leads to children who are better or not better adjusted. © 2015 Michigan Association for Infant Mental Health.

Regional Infant and Child Mortality Review Committee 2013 final report.

2015-02-01

The Regional Infant and Child Review Committee serves 10 counties in southeastern South Dakota and its mission is to review of deaths of infants and children under the age of 18 so that information can be transformed into action to protect young lives. In 2013, the committee's interdisciplinary team reviewed 32 deaths that met its criteria. The manner of 13 of these deaths was natural, nine accidental, one homicide, five suicide, and four undetermined. There were five infant deaths during sleep and each of these occurred in an unsafe sleep environment. The number of suicides in 2013 was considerably higher than the typical one death by suicide that previously has been observed per year in the area. The report provides the Committee's recommendations for community action that could prevent future deaths of infants and children.

Reliability of classification performance is important for many biomedical applications. A classification model which considers reliability in the development of the model such that unreliable segments are rejected would be useful, particularly, in large biomedical data sets. This approach is demonstrated in the development of a technique to reliably determine sleep and wake using only the electrocardiogram (ECG) of infants. Typically, sleep state scoring is a time consuming task in which sleep states are manually derived from many physiological signals. The method was tested with simultaneous 8-h ECG and polysomnogram (PSG) determined sleep scores from 190 infants enrolled in the collaborative home infant monitoring evaluation (CHIME) study. Learning vector quantization (LVQ) neural network, multilayer perceptron (MLP) neural network, and support vector machines (SVMs) are tested as the classifiers. After systematic rejection of difficult to classify segments, the models can achieve 85%-87% correct classification while rejecting only 30% of the data. This corresponds to a Kappa statistic of 0.65-0.68. With rejection, accuracy improves by about 8% over a model without rejection. Additionally, the impact of the PSG scored indeterminate state epochs is analyzed. The advantages of a reliable sleep/wake classifier based only on ECG include high accuracy, simplicity of use, and low intrusiveness. Reliability of the classification can be built directly in the model, such that unreliable segments are rejected.

Objective Pulse oximetry is used extensively in hospital and home settings to measure arterial oxygen saturation (SpO2). Interpretation of the trend and range of SpO2 values observed in infants is currently limited by a lack of reference ranges using current devices, and may be augmented by development of cumulative frequency (CF) reference-curves. This study aims to provide reference oxygen saturation values from a prospective longitudinal cohort of healthy infants. Design Prospective longitudinal cohort study. Setting Sleep-laboratory. Patients 34 healthy term infants were enrolled, and studied at 2 weeks, 3, 6, 12 and 24 months of age (N=30, 25, 27, 26, 20, respectively). Interventions Full overnight polysomnography, including 2 s averaging pulse oximetry (Masimo Radical). Main outcome measurements Summary SpO2 statistics (mean, median, 5th and 10th percentiles) and SpO2 CF plots were calculated for each recording. CF reference-curves were then generated for each study age. Analyses were repeated with sleep-state stratifications and inclusion of manual artefact removal. Results Median nocturnal SpO2 values ranged between 98% and 99% over the first 2 years of life and the CF reference-curves shift right by 1% between 2 weeks and 3 months. CF reference-curves did not change with manual artefact removal during sleep and did not vary between rapid eye movement (REM) and non-REM sleep. Manual artefact removal did significantly change summary statistics and CF reference-curves during wake. Conclusions SpO2 CF curves provide an intuitive visual tool for evaluating whether an individual's nocturnal SpO2 distribution falls within the range of healthy age-matched infants, thereby complementing summary statistics in the interpretation of extended oximetry recordings in infants.

Preterm infants are exposed to loud noises during their stay in the neonatal intensive care unit which can lead to physiologic and behavioral alterations and even hearing loss. The use of earmuffs can reduce sound level and these changes. The objective of the present study is to evaluate the effectiveness of the earmuffs in preterm infants solely cared for in closed incubators. A comparative prospective study comprising 20 clinically stable preterm infants weighing less than 1500 g cared in closed incubator was conducted. Preterm infants acted as their own controls whereby they were observed without earmuffs (Group 1) for 2 days and with earmuffs (Group 2) on consecutive 2 days. The preterm infants' physiologic responses and Anderson Behavioral State Scoring System (ABSS) scores were assessed over 30s every 2h for 8h during daytime for 4 days. Out of 20 preterm infants, 6 were male and 14 female with a mean birth weight of 1220 ± 209 g, gestational age of 29.9 ± 2.1 weeks. The total number of measurements was 320. The mean ABSS scores of Group 1 and 2 were 3.07±1.1 and 1.34 ± 0.3, respectively. Statistically significant difference was noted between the means of ABSS scores (p<0.001). Preterm infants with earmuffs (87.5%) were more frequently observed in a quiet sleep state of ABSS compared with those without earmuffs (29.4%). Noise level reduction was associated with significant improvement in behavioral states of ABSS. We suggest that noise reduction in preterm infants with earmuffs is helpful by improving sleep efficiency and increasing time of quiet sleep. Copyright © 2012 Elsevier Ireland Ltd.

Kangaroo Mother Care (KMC) supports parents' role at the neonatal intensive care unit (NICU). To enhance parents' provision of KMC, it is essential to obtain knowledge of what parents perceive as supportive factors and barriers regarding their opportunities to perform KMC. To identify factors that parents of preterm infants perceived as supportive factors or barriers for their performance of KMC and to explore the timing of and reasons for parents' discontinuation of KMC. A descriptive study performed at two NICUs in Sweden with 76 mothers and 74 fathers of preterm infants born at gestational ages ranging from 28 to 33 weeks. Data on infant characteristics were obtained from the infants' medical records. A questionnaire, based on scientific literature and the researchers' clinical experience, was completed by the mothers and the fathers separately, shortly after the infant's discharge from the hospital. The data were analyzed with qualitative content analysis and descriptive statistic. Four categories were identified in parents' responses regarding support and barriers for their performance of KMC: Parent related factors, Time, Infants related factors and The NICU and home environment. The hospital staff and environment were described by the parents as both supportive and barriers for their application of KMC. Some mothers described the infants' feeding process as an obstacle to KMC. Sleeping with the infant skin-to-skin in the same position throughout the night could be difficult, as an uncomfortable sleeping position caused insufficient sleep. A majority of both mothers and fathers continued providing their infant with KMC to some extent after discharge. Interventions for enhancing parents' opportunities for performing KMC should address both hospital staff attitudes and practices and the NICU environment. © 2012 Nordic College of Caring Science.

Purpose Determine perceptions about positioning for preterm infants in the NICU. Design Twenty-item survey Sample Neonatal nurses (n=68) and speech, physical, and occupational therapists (n=8). Main Outcome Variable Perceptions about positioning were obtained, and differences in perceptions between nurses and therapists were explored. Results Ninety-nine percent of respondents agreed that positioning is important for the well-being of the infant. Sixty-two percent of nurses and 86% of therapists identified the Dandle Roo as the ideal method of neonatal positioning. Forty-four percent of nurses and 57% of therapists reported the Dandle Roo is the easiest positioning method to use in the NICU. Some perceptions differed: therapists were more likely to report the Sleep Sack does not hold the infant in good alignment. Nurses were more likely to report the infant does not sleep well in traditional positioning. PMID:23477978

The Microstructure of Active and Quiet Sleep as Cortical Delta Activity Emerges in Infant Rats

PubMed Central

Seelke, Adele M. H.; Blumberg, Mark S.

2008-01-01

Study objectives: Previous investigators have suggested that quiet sleep (QS) in rats develops rapidly upon the emergence of cortical delta activity around postnatal day (P)11 and that the presence of “half-activated” active sleep (AS) suggests that infant sleep is initially disorganized. To address these issues, we examined the temporal organization of sleep states during the second postnatal week in rats as delta activity emerges. Design: Subjects were P9, P11, and P13 Sprague-Dawley rats. Electroencephalogram and nuchal electromyogram electrodes were implanted, and data were recorded at thermoneutrality for 2 hours. Results: At all ages, using electromyogram and behavioral criteria, QS (defined as nuchal atonia and behavioral quiescence) dominated the first third of each sleep period, whereas AS (defined as nuchal atonia accompanied by myoclonic twitching) dominated the last third. When delta activity, which was first detected at P11, could be added to the definition of QS, gross assessments of sleep-state organization were not altered, although it was now possible to identify brief periods of QS interposed between periods of AS. No evidence of “half-activated” AS was found. Finally, “slow activity transients” were detected and were primarily associated with QS; their rate of occurrence declined as delta activity emerged. Conclusions: When delta activity emerges at P11, it integrates smoothly with periods of QS, as defined using electromyogram and behavioral criteria alone. Delta activity helps to refine estimates of QS duration but does not reflect a significant alteration of sleep-state organization. Rather, this organization is expressed much earlier in ontogeny as fluctuations in muscle tone and associated phasic motor activity. Citation: Seelke AMH; Blumberg MS.

2017-01-01

The objective of this study was to design a non-invasive system for the observation of respiratory rates and detection of apnoea using analysis of real time image sequences captured in any given sleep position and under any light conditions (even in dark environments). A Microsoft Kinect sensor was used to visualize the variations in the thorax and abdomen from the respiratory rhythm. These variations were magnified, analyzed and detected at a distance of 2.5 m from the subject. A modified motion magnification system and frame subtraction technique were used to identify breathing movements by detecting rapid motion areas in the magnified frame sequences. The experimental results on a set of video data from five subjects (3 h for each subject) showed that our monitoring system can accurately measure respiratory rate and therefore detect apnoea in infants and young children. The proposed system is feasible, accurate, safe and low computational complexity, making it an efficient alternative for non-contact home sleep monitoring systems and advancing health care applications.

2004-11-01

Clinical significance of neonatal positive temporal sharp waves (PTS) is controversial. The aim of this work is to study (1) PTS incidence in preterm infants with or without major ultrasound lesion (MUL) per gestational age (GA), and (2) the relationship between PTS in both sleep states and other electroencephalographic (EEG) findings with poor prognoses. 97 preterm infants of <27-36 weeks GA, and 12 full-term healthy infants were presented. Prospective study included (1) neurodevelopmental assessment at 40-42 weeks conceptional age (CA), (2) serial neurosonography, and (3) EEG recording at postnatal week 1, 2, 4 and at 40-42 weeks CA. In 50 neonates without MUL, peak PTS was at 31-32 weeks GA. In 47 neonates with MUL, PTS increased significantly from week 2 after birth, descending at the 4th. Neonates of <33 weeks GA with MUL showed significantly increased PTS at term. A significant relationship was found between PTS and other EEG abnormalities with poor neurologic prognoses. PTS incidence varied with sleep states, being predominant in indeterminate sleep in neonates with MUL. PTS increased significantly in infants with MUL, mainly at week 2 of postnatal life, persisting high until term CA, and correlated with other abnormal EEG findings. PTS are highly sensitive to MUL.

Aims To investigate the correlation between the ‘perfusion index’ (PI) and other commonly used estimates of cutaneous blood flow [heart rate (HR), surface temperatures (ST) and central-to-peripheral thermal gradients (C-P grad)] and to use this new non-invasive tool to compare differences between prone and supine sleep position in low birth weight (LBW) infants. Methods Six-hour continuous recordings of pulse oximetry, cardiac activity and absolute ST from three sites (flank, forearm and leg), along with minute-to-minute assessment of behavioural states were performed in 31 LBW infants. Infants were randomly assigned to the prone or supine position for the first 3 h and then reversed for the second 3 h. PI data were correlated with HR and C-P grad, and compared across sleep positions during quiet sleep (QS) and active sleep (AS). Results Perfusion index correlated significantly with HR (r2 = 0.40) and flank-to-forearm thermal gradient (r2 = 0.28). In the prone position during QS, infants exhibited higher PI (3.7 ± 0.9 vs. 3.1 ± 0.7), HR (158.4 ± 8.9 vs. 154.1 ± 8.8 bpm), SpO2 (95.8 ± 2.6 vs. 95.2 ± 2.6%), flank (36.7 ± 0.4 vs. 36.5 ± 0.4°C), forearm (36.1 ± 0.6 vs. 35.5 ± 0.4°C) and leg (35.4 ± 0.7 vs. 34.7 ± 0.7°C) temperatures and narrower flank-to-forearm (0.6 ± 0.4 vs. 0.9 ± 0.3°C) and flank-to-leg (1.3 ± 0.6 vs. 1.8 ± 0.7°C) gradients, compared to those of the supine position. Similar differences were observed during AS. Conclusion Perfusion index is a good non-invasive estimate of tissue perfusion. Prone sleeping position is associated with a higher PI, possibly reflecting thermoregulatory adjustments in cardiovascular control. The effects of these position-related changes may have important implications for the increased risk for sudden infant death syndrome in prone position. PMID:19785632

Ji, Xiaopeng; Grandner, Michael A; Liu, Jianghong

2017-01-01

Objective To review articles on the relationship of dietary and circulating micronutrients with sleep patterns, and to identify issues surrounding implications for future research and public health practice. Design A systematic review was conducted. PubMed, Embase and Scopus were searched through January 2016. Setting Both experimental and observational studies were included. However, studies that focused on secondary sleep impairment due to comorbidities were excluded. Subjects Individuals in different age groups, from infants to older adults. Results A total of twenty-six articles were selected. In the articles reviewed, researchers generally supported a potential role of micronutrients, particularly Fe and Mg, in the development of sleep stages among infants and in reversing age-related alterations in sleep architecture in older adults. Micronutrient status has also been linked to sleep duration, with sleep duration positively associated with Fe, Zn and Mg levels, and negatively associated with Cu, K and vitamin B12 levels. The mechanisms underlying these relationships include the impact of micronutrients on excitatory/inhibitory neurotransmitters and the expression of circadian genes. Conclusions Although the number of studies on the relationship between micronutrient status and sleep remains low, evidence has emerged that suggests a link between dietary/circulating micronutrients and sleep. Future research is needed to investigate the dose-dependent as well as the longitudinal relationships between micronutrient levels and human sleep across populations, test the interactions among micronutrients on sleep outcomes, and ultimately examine the clinical relevance of micronutrients on sleep health.

Sleep duration and disorders in pregnancy: implications for glucose metabolism and pregnancy outcomes

PubMed Central

O’Keeffe, M; St-Onge, M-P

2013-01-01

Humans have an innate requirement for sleep that is intrinsically governed by circadian and endocrine systems. More recently, reduced sleep duration has gained significant attention for its possible contribution to metabolic dysfunction. Significant evidence suggests that reduced sleep duration may elevate the risk for impaired glucose functioning, insulin resistance and type 2 diabetes. However, to date, few studies have determined the implications of reduced sleep duration with regard to glucose control during pregnancy. With the high prevalence of overweight and obesity in women of reproductive age, the occurrence of gestational diabetes mellitus (GDM) is increasing. GDM results in elevated risk of maternal and fetal complications, as well as increased risk of type 2 diabetes postpartum. Infants born to women with GDM also carry a life-long risk of obesity and type 2 diabetes. The impact of reduced sleep on glucose management during pregnancy has not yet been fully assessed and a paucity of literature currently exits. Herein, we review the association between reduced sleep and impaired carbohydrate metabolism and propose how reduced sleep during pregnancy may result in further dysfunction of the carbohydrate axis. A particular focus will be given to sleep-disordered breathing, as well as GDM-complicated pregnancies. Putative mechanisms of action by which reduced sleep may adversely affect maternal and infant outcomes are also discussed. Finally, we will outline important research questions that need to be addressed. PMID:22945608

Maternal Caffeine Consumption and Infant Nighttime Waking: Prospective Cohort Study

PubMed Central

Santos, Iná S.; Matijasevich, Alicia

2012-01-01

OBJECTIVE: Coffee and other caffeinated beverages are commonly consumed in pregnancy. In adults, caffeine may interfere with sleep onset and have a dose-response effect similar to those seen during insomnia. In infancy, nighttime waking is a common event. With this study, we aimed to investigate if maternal caffeine consumption during pregnancy and lactation leads to frequent nocturnal awakening among infants at 3 months of age. METHODS: All children born in the city of Pelotas, Brazil, during 2004 were enrolled on a cohort study. Mothers were interviewed at delivery and after 3 months to obtain information on caffeine drinking consumption, sociodemographic, reproductive, and behavioral characteristics. Infant sleeping pattern in the previous 15 days was obtained from a subsample. Night waking was defined as an episode of infant arousal that woke the parents during nighttime. Multivariable analysis was performed by using Poisson regression. RESULTS: The subsample included 885 of the 4231 infants born in 2004. All but 1 mother consumed caffeine in pregnancy. Nearly 20% were heavy consumers (≥300 mg/day) during pregnancy and 14.3% at 3 months postpartum. Prevalence of frequent nighttime awakeners (>3 episodes per night) was 13.8% (95% confidence interval: 11.5%–16.0%). The highest prevalence ratio was observed among breastfed infants from mothers consuming ≥300 mg/day during the whole pregnancy and in the postpartum period (1.65; 95% confidence interval: 0.86–3.17) but at a nonsignificant level. CONCLUSIONS: Caffeine consumption during pregnancy and by nursing mothers seems not to have consequences on sleep of infants at the age of 3 months. PMID:22473365

Sleeping sites, sleeping trees, and sleep-related behaviors of black crested gibbons (Nomascus concolor jingdongensis) at Mt. Wuliang, Central Yunnan, China.

PubMed

Fan, Peng-Fei; Jiang, Xue-Long

2008-02-01

Data on sleep-related behaviors were collected for a group of central Yunnan black crested gibbons (Nomascus concolor jingdongensis) at Mt. Wuliang, Yunnan, China from March 2005 to April 2006. Members of the group usually formed four sleeping units (adult male and juvenile, adult female with one semi-dependent black infant, adult female with one dependent yellow infant, and subadult male) spread over different sleeping trees. Individuals or units preferred specific areas to sleep; all sleeping sites were situated in primary forest, mostly (77%) between 2,200 and 2,400 m in elevation. They tended to sleep in the tallest and thickest trees with large crowns on steep slopes and near important food patches. Factors influencing sleeping site selection were (1) tree characteristics, (2) accessibility, and (3) easy escape. Few sleeping trees were used repeatedly by the same or other members of the group. The gibbons entered the sleeping trees on average 128 min before sunset and left the sleeping trees on average 33 min after sunrise. The lag between the first and last individual entering the trees was on average 17.8 min. We suggest that sleep-related behaviors are primarily adaptations to minimize the risk of being detected by predators. Sleeping trees may be chosen to make approach and attack difficult for the predator, and to provide an easy escape route in the dark. In response to cold temperatures in a higher habitat, gibbons usually sit and huddle together during the night, and in the cold season they tend to sleep on ferns and/or orchids.

Thirty-four typically developing infants were assigned randomly to nap and wake groups. After teaching two novel object-word pairs to infants, we tested their initial performance with an intermodal preferential looking task in which infants are expected to increase their target looking time compared to a distracter after hearing its auditory label. A second test session followed after approximately a 2-h delay. The delay contained sleep for the nap group or no sleep for the wake group. Looking behaviour was measured with an automatic eye-tracker. Vocabulary size was assessed using the Oxford Communicative Development Inventory. A significant interaction between group and session was found in preferential looking towards the target picture. The performance of the nap group increased after the nap, whereas that of the wake group did not change. The gain in performance correlated positively with the expressive vocabulary size in the nap group. These results indicate that daytime napping helps consolidate word learning in infancy. © 2015 European Sleep Research Society.

A strong association between infant bed sharing and sudden infant death syndrome or unintentional sleep-related death in infants has been established. Occurrences of unintentional sleep-related deaths among infants appear to be increasing. To determine the trends and factors associated with infant bed sharing from 1993 through 2010, including the association of physician advice on bed sharing. National Infant Sleep Position study conducted with annual telephone surveys. The 48 contiguous states. Nighttime caregivers of infants born within 7 months of each survey administration. Approximately 1000 interviews were completed annually. Infant bed sharing as a usual practice. Of 18 986 participants, 11.2% reported an infant sharing a bed as a usual practice. Bed sharing increased from 1993 (6.5%) to 2010 (13.5%). Although bed sharing increased significantly among white respondents from 1993 to 2000 (P < .001), the increase from 2001 to 2010 was not significant (P = .48). Black and Hispanic respondents reported an increase in bed sharing throughout the study period, with no difference between the earlier and later periods (P = .63 and P = .77, respectively). After accounting for the study year, factors associated with increase in infant bed sharing as a usual practice included maternal educational level of less than high school compared with college or greater (adjusted odds ratio, 1.42 [95% CI, 1.12-1.79]); black (3.47 [2.97-4.05]), Hispanic (1.33 [1.10-1.61]), and other (2.46 [2.03-2.97]) maternal race or ethnicity compared with white race; household income of less than $20,000 (1.69 [1.44-1.99]) and $20,000 to $50,000 (1.29 [1.14-1.45]) compared with greater than $50,000; living in the West (1.61 [1.38-1.88]) or the South (1.47 [1.30-1.66]) compared with the Midwest; infants younger than 8 weeks (1.45 [1.21-1.73]) or ages 8 to 15 weeks (1.31 [1.17-1.45]) compared with 16 weeks or older; and being born prematurely compared with full-term (1.41 [1.22-1.62]). Almost 46% of the participants reported talking to a physician about bed sharing. Compared with those who did not receive advice from a physician, those who reported their physicians had a negative attitude were less likely to have the infant share a bed (adjusted odds ratio, 0.66 [95% CI, 0.53-0.82]), whereas a neutral attitude was associated with increased bed sharing (1.38 [1.05-1.80]). Our finding of a continual increase in bed sharing throughout the study period among black and Hispanic infants suggests that the current American Academy of Pediatrics recommendation about bed sharing is not universally followed. The factors associated with infant bed sharing may be useful in evaluating the impact of a broad intervention to change behavior.

Pulse oximetry is used extensively in hospital and home settings to measure arterial oxygen saturation (SpO2). Interpretation of the trend and range of SpO2 values observed in infants is currently limited by a lack of reference ranges using current devices, and may be augmented by development of cumulative frequency (CF) reference-curves. This study aims to provide reference oxygen saturation values from a prospective longitudinal cohort of healthy infants. Prospective longitudinal cohort study. Sleep-laboratory. 34 healthy term infants were enrolled, and studied at 2 weeks, 3, 6, 12 and 24 months of age (N=30, 25, 27, 26, 20, respectively). Full overnight polysomnography, including 2 s averaging pulse oximetry (Masimo Radical). Summary SpO2 statistics (mean, median, 5th and 10th percentiles) and SpO2 CF plots were calculated for each recording. CF reference-curves were then generated for each study age. Analyses were repeated with sleep-state stratifications and inclusion of manual artefact removal. Median nocturnal SpO2 values ranged between 98% and 99% over the first 2 years of life and the CF reference-curves shift right by 1% between 2 weeks and 3 months. CF reference-curves did not change with manual artefact removal during sleep and did not vary between rapid eye movement (REM) and non-REM sleep. Manual artefact removal did significantly change summary statistics and CF reference-curves during wake. SpO2 CF curves provide an intuitive visual tool for evaluating whether an individual's nocturnal SpO2 distribution falls within the range of healthy age-matched infants, thereby complementing summary statistics in the interpretation of extended oximetry recordings in infants.

Cortisol, the end product of the hypothalamic-pituitary-adrenal axis, plays an important role in modulating sleep. Yet, studies investigating the association between diurnal cortisol rhythm and sleep patterns in young children are scarce. We tested the hypothesis that the diurnal cortisol rhythm is associated with shorter sleep duration and more sleep problems across early childhood. This study was embedded in Generation R, a population-based cohort from fetal life onward. Parents collected saliva samples from their infant at five moments during day 1. In 322 infants aged 12 to 20 months, we determined the diurnal cortisol rhythm by calculating the area under the curve (AUC), the cortisol awakening response (CAR), and the diurnal slope. Sleep duration and sleep behavior were repeatedly assessed across ages of 14 months to 5 years. Generalized estimating equation models were used to assess related cortisol measures to sleep duration and sleep behavior. The diurnal cortisol slope and the CAR, but not the AUC, were associated with sleep duration across childhood. Children with flatter slopes and children with a more positive CAR were more likely to have shorter nighttime sleep duration (β per nmol/L/h slope = -0.12, 95% confidence interval = -0.19 to -0.05, p = .001; β per nmol/L CAR = -0.01, 95% confidence interval = -0.02 to 0.00, p = .04). Cortisol measures did not predict sleep problems. The present study suggests that a flatter diurnal cortisol slope and a more marked morning rise, which can indicate stress (or hypothalamic-pituitary-adrenal dysregulation), have a long-term association with sleep regulation.

With rapid urbanization and life style changes, loud noise is omnipresent and has become a part of life. Indoor and outdoor environmental noise pollution have been documented as a serious health hazard with increasing adverse effects on fetus, infants, children, adolescents and adults. Noise induced hearing loss and non-auditory adverse effects due to noise pollution, are being increasingly diagnosed in all age groups including the fetus. Outdated motorized vehicles, machinery, increasing traffic, congested residential areas, crowded educational institutions and workplaces, unregulated commercial and industrial noise have become a source of noise pollution with long-term disability. Areas of noise pollution must be identified and corrective measures be taken. Toys, personal, domestic, commercial, industrial equipment should be within the safe sound intensity. Loudspeakers and vehicular horns should be banned except in emergencies. Nocturnal noise pollution must be avoided near residential areas as sleep disturbances have serious long-term health consequences. Pregnant women, fetus, newborns, infants and children are most susceptible to noise induced health hazards and should be given utmost protection. Educational institutions, workplaces, commercial and industrial areas should be regularly monitored for noise levels and protective ear muffs and plugs be used. Public be educated repeatedly regarding health hazards of noise. Traffic noise should be regulated to be within safe limits. Bus-stands, railway stations and airports should be moved away from residential areas. Houses should be sound proofed suitably. Long term studies should be conducted in pregnant women, newborn children and adults to have more data on hazards of noise pollution.

Morphological changes in preterm infants with bronchopulmonary dysplasia (BPD) have functional consequences on lung volume, ventilation inhomogeneity and respiratory mechanics. Although some studies have shown lower lung volumes and increased ventilation inhomogeneity in BPD infants, conflicting results exist possibly due to differences in sedation and measurement techniques. We studied 127 infants with BPD, 58 preterm infants without BPD and 239 healthy term-born infants, at a matched post-conceptional age of 44 weeks during quiet natural sleep according to ATS/ERS standards. Lung function parameters measured were functional residual capacity (FRC) and ventilation inhomogeneity by multiple breath washout as well as tidal breathing parameters. Preterm infants with BPD had only marginally lower FRC (21.4 mL/kg) than preterm infants without BPD (23.4 mL/kg) and term-born infants (22.6 mL/kg), though there was no trend with disease severity. They also showed higher respiratory rates and lower ratios of time to peak expiratory flow and expiratory time (t(PTEF)/t(E)) than healthy preterm and term controls. These changes were related to disease severity. No differences were found for ventilation inhomogeneity. Our results suggest that preterm infants with BPD have a high capacity to maintain functional lung volume during natural sleep. The alterations in breathing pattern with disease severity may reflect presence of adaptive mechanisms to cope with the disease process.

To explore the current television viewing situation among children less than 4 years of age in our country and investigate effects of television viewing on sleep quality. According to the"Hospital of Province-City-County"sampling technical route, a total of 1 046 full term healthy children at the age of 4-48 months were sampled by stratified cluster random sampling method from 8 provinces in China from 2012-2013. The information of television viewing and family and personal information was investigated by Shanghai Children's Medical Center Socio-demographic Questionnaire. Brief Infant Sleep Questionnaire (BISQ) and Brief Child Sleep Questionnaire (BCSQ) were employed to assess the sleep behaviors of children 0-3 years old and over 3 years old respectively.The effects of television viewing on sleep quality were analyzed by multiple linear regression analysis. The children's average age was (20±13) months, with boys accounted for 53.3% (558/1 046). The percentage of children who viewed television was 70.3% (735/1 046). Moreover, 58.7% (408/695) of infants and young children under the age of 2 viewed TV per day, and 19.9% (70/351) of 2 years and older infants and young children viewed television ≥2 hours per day. With the increase of age, the percentage of children who viewed television time gradually increased (P<0.001). Child sex, geographic area, paternal education, and family structure were not associated with television viewing time among children aged 4-48 months. However, the presence of a bedroom TV(χ(2)=13.682, P=0.001) and maternal employment (χ(2)=15.053, P=0.005) were commonly correlated with long screen-watching time among children. After adjusting for age, gender, mother' education level, and working state, it was revealed by multiple linear regression analysis that television viewing was not only positively correlated with later bedtime (t=5.49, P<0.001) and shorter night sleep duration (t=-3.49, P=0.001) but also significantly associated with longer sleep onset latency (t=2.63, P=0.009). The percentage of children under 4 years of age who viewed television is very high in our country, and many infants under 6 months of age exposed to TV environment. Bedroom TV and mother full-time job were associated with higher proportion of children viewing TV. In early childhood, television viewing was positively correlated with later bedtime, shorter sleep duration and longer sleep onset latency. There is a need for parents and pediatricians to pay more attention to the behavior of children viewing TV and improve sleep quality.

The Brainstem and Serotonin in the Sudden Infant Death Syndrome

2012-01-01

The sudden infant death syndrome (SIDS) is the sudden death of an infant under one year of age that is typically associated with sleep and that remains unexplained after a complete autopsy and death scene investigation. A leading hypothesis about its pathogenesis is that many cases result from defects in brainstem-mediated protective responses to homeostatic stressors occurring during sleep in a critical developmental period. Here we review the evidence for the brainstem hypothesis in SIDS with a focus upon abnormalities related to the neurotransmitter serotonin in the medulla oblongata, as these are the most robust pathologic findings to date. In this context, we synthesize the human autopsy data with genetic, whole-animal, and cellular data concerning the function and development of the medullary serotonergic system. These emerging data suggest an important underlying mechanism in SIDS that may help lead to identification of infants at risk and specific interventions to prevent death. PMID:19400695

Hypothesis on supine sleep, sudden infant death syndrome reduction and association with increasing autism incidence

Bergman, Nils J

AIM To identify a hypothesis on: Supine sleep, sudden infant death syndrome (SIDS) reduction and association with increasing autism incidence. METHODS Literature was searched for autism spectrum disorder incidence time trends, with correlation of change-points matching supine sleep campaigns. A mechanistic model expanding the hypothesis was constructed based on further review of epidemiological and other literature on autism. RESULTS In five countries (Denmark, United Kingdom, Australia, Israel, United States) with published time trends of autism, change-points coinciding with supine sleep campaigns were identified. The model proposes that supine sleep does not directly cause autism, but increases the likelihood of expression of a subset of autistic criteria in individuals with genetic susceptibility, thereby specifically increasing the incidence of autism without intellectual disability. CONCLUSION Supine sleep is likely a physiological stressor, that does reduce SIDS, but at the cost of impact on emotional and social development in the population, a portion of which will be susceptible to, and consequently express autism. A re-evaluation of all benefits and harms of supine sleep is warranted. If the SIDS mechanism proposed and autism model presented can be verified, the research agenda may be better directed, in order to further decrease SIDS, and reduce autism incidence. PMID:27610351

Previous studies have demonstrated that a light-dark cycle has promoted better sleep development and weight gain in preterm infants than constant light or constant darkness. However, it was unknown whether brief light exposure at night for medical treatment and nursing care would compromise the benefits brought about by such a light-dark cycle. To examine such possibility, we developed a special red LED light with a wavelength of >675 nm which preterm infants cannot perceive. Preterm infants born at <36 weeks’ gestational age were randomly assigned for periodic exposure to either white or red LED light at night in a light-dark cycle after transfer from the Neonatal Intensive Care Unit to the Growing Care Unit, used for supporting infants as they mature. Activity, nighttime crying and body weight were continuously monitored from enrolment until discharge. No significant difference in rest-activity patterns, nighttime crying, or weight gain was observed between control and experimental groups. The data indicate that nursing care conducted at 3 to 4-hour intervals exposing infants to light for <15 minutes does not prevent the infants from developing circadian rest-activity patterns, or proper body growth as long as the infants are exposed to regular light-dark cycles.

Poor sleep quality is related to old age among the general population, but few studies have focused on postpartum women of advanced maternal age. The present study aimed to describe and compare sleep quality between women younger or older than 35 years of age at 3 months postpartum, and to examine the related factors. A cross-sectional survey was conducted with 160 postpartum women who had given birth at a teaching hospital in Taiwan. The participants were assigned to two groups according to age (≥35 years, n=80; and 20-34 years, n=80). Sleep quality was measured using the Pittsburgh Sleep Quality Index with a cut-off score of 5. The prevalence of poor sleep quality at 3 months postpartum was higher in older mothers (61.6%) than in younger mothers (38.4%, p<0.01). Multiple logistic regression revealed that poor sleep quality was positively correlated with the severity of postpartum physical symptoms, lack of exercise, and room-sharing with infants. After adjustment for those variables, older mothers were three times more likely to have poor sleep quality than younger mothers (odds ratio=3.08; 95% confidence interval 1.52-6.23). Health care providers should pay attention to sleep problems among postpartum women, especially mothers of advanced maternal age. In particular, health care providers should evaluate sleep quality among postpartum women, instruct them not to share the bed with their infants at night, perform exercise, and manage their postpartum physical symptoms to improve the sleep quality.

Thermal insulation and SIDS-an investigation of selected 'Eastern' and 'Western' infant bedding combinations.

PubMed

Wilson, C A; Chu, M S

2005-08-01

Differences in the incidence of SIDS between 'Western' and 'Eastern' countries has been attributed to cultural practices, which may affect the infants care and thermal environment. The purpose of this work was to estimate for selected 'commonly' used bedding, sleep positions and practices in Japan, Korea and New Zealand, the intrinsic 'dry' thermal resistance of bedding. Insulation levels are also discussed in the context of published information about the thermal environment in which the bedding is likely to be used. Selected Japanese, Korean and New Zealand bedding was loosely tucked over an infant manikin in the lateral, prone and supine sleep positions. Thickness in use was measured, and intrinsic 'dry' thermal resistance estimated using the Wilson Laing model which accommodates the effect on insulation of the three-dimensional arrangement of bedding combinations during use. Thickness of under- and upper-bedding varied among countries with thickness and estimated 'dry' thermal resistance of the upper-bedding affected by the type/combination of bedding and the infants sleep position. Insulation levels are discussed in relation to environmental conditions within and among countries and between seasons. Further information on thermal environments, bedding combinations used and care practices within both Asian and Western countries is needed. 'Eastern' infants appear likely to be generally covered in bedding combinations of greater insulation than those used to cover 'Western' infants in comparable seasons. Differences existed between insulation of the Japanese and Korean bedding combinations investigated. Lower rates of SIDS apparent in 'Asian' populations do not appear attributable to use of lower levels of bedding insulation only.

Time course of EEG background activity level before spontaneous awakening in infants.

Zampi, Chiara; Fagioli, Igino; Salzarulo, Piero

2002-12-01

This research aimed to investigate the time course of the cortical activity level preceding spontaneous awakening as a function of age and state. Two groups of infants (1-4 and 9-14 weeks of age) were continuously monitored by polygraphic recording and behavioural observation during the night. The electroencephalographic (EEG) activity recorded by the C3-O1 lead was analysed through an automatic analysis method which provides, for each 30-s epoch, a single measure, time domain based, of the EEG synchronization. The EEG parameter values were computed in the 6 min preceding each awakening out of non-rapid eye movement (NREM) sleep and out of rapid eye movement (REM) sleep. The EEG background activity level did not change in the minutes preceding awakening out of REM sleep. Awakening out of NREM sleep was preceded by a change of EEG activity level in the direction of higher activation with different time course according to the age. Both REM and NREM sleep results suggest that a high level of EEG activity is a prerequisite for the occurrence of a spontaneous awakening.

The early literature suggests that hypoventilation in infants with congenital central hypoventilation syndrome (CHS) is less severe during rapid eye movement (REM) than during non-REM (NREM) sleep. However, this supposition has not been rigorously tested, and subjects older than infancy have not been studied. Given the differences in anatomy, physiology, and REM sleep distribution between infants and older children, and the reduced number of limb movements during REM sleep, we hypothesized that older subjects with CHS would have more severe hypoventilation during REM than NREM sleep. Nine subjects with CHS, aged (mean +/- SD) 13 +/- 7 yr, were studied. Spontaneous ventilation was evaluated by briefly disconnecting the ventilator under controlled circumstances. Arousal was common, occurring in 46% of REM vs. 38% of NREM trials [not significant (NS)]. Central apnea occurred during 31% of REM and 54% of NREM trials (NS). Although minute ventilation declined precipitously during both REM and NREM trials, hypoventilation was less severe during REM (drop in minute ventilation of 65 +/- 23%) than NREM (drop of 87 +/- 16%, P = 0.036). Despite large changes in gas exchange during trials, there was no significant change in heart rate during either REM or NREM sleep. We conclude that older patients with CHS frequently have arousal and central apnea, in addition to hypoventilation, when breathing spontaneously during sleep. The hypoventilation in CHS is more severe during NREM than REM sleep. We speculate that this may be due to increased excitatory inputs to the respiratory system during REM sleep.

Using social marketing to increase awareness of the African American infant mortality disparity.

African American infants in San Francisco suffer a mortality rate two to three times higher than Whites, yet prior discussion groups with African American residents suggested they were unaware of this disparity. Social marketing techniques were used to develop and implement three campaigns to increase awareness. The campaign themes were (1) infant mortality disparities, (2) proper infant sleep position, and (3) taking action to reduce disparities. Mediums to carry messages included bus ads, radio ads, church fans, and posters and cards distributed at clinics, daycares, agency waiting rooms, and community organizations. Campaign effectiveness was evaluated using telephone surveys of African Americans. Almost 62% report some exposure to Campaign 1, 48.5% to Campaign 2, and 48.9% to Campaign 3. Chi-square analyses reveal a statistically ignificant increase in awareness of the disparity (39.6% vs. 62.7%, p < .0005, odds ratio [OR] = 2.5, confidence interval [CI] = 2.1-3.2). Although there was no overall significant increase in knowledge about proper sleep position, respondents who report any exposure to this campaign are more likely to know about sleep position (70.7% vs. 63.8%, p < .0001, OR = 2.2, CI = 1.6-3.2). Social marketing is an effective tool to increase disparity awareness, especially among groups disproportionately affected by the disparity.

Overnight changes in the slope of sleep slow waves during infancy.

2014-02-01

Slow wave activity (SWA, 0.5-4.5 Hz) is a well-established marker for sleep pressure in adults. Recent studies have shown that increasing sleep pressure is reflected by an increased synchronized firing pattern of cortical neurons, which can be measured by the slope of sleep slow waves. Thus we aimed at investigating whether the slope of sleep slow waves might provide an alternative marker to study the homeostatic regulation of sleep during early human development. All-night sleep electroencephalography (EEG) was recorded longitudinally at 2, 4, 6, and 9 months after birth. Home recording. 11 healthy full-term infants (5 male, 6 female). None. The slope of sleep slow waves increased with age. At all ages the slope decreased from the first to the last hour of non rapid-eye-movement (NREM) sleep, even when controlling for amplitude differences (P < 0.002). The decrease of the slope was also present in the cycle-by-cycle time course across the night (P < 0.001) at the age of 6 months when the alternating pattern of low-delta activity (0.75-1.75 Hz) is most prominent. Moreover, we found distinct topographical differences exhibiting the steepest slope over the occipital cortex. The results suggest an age-dependent increase in synchronization of cortical activity during infancy, which might be due to increasing synaptogenesis. Previous studies have shown that during early postnatal development synaptogenesis is most pronounced over the occipital cortex, which could explain why the steepest slope was found in the occipital derivation. Our results provide evidence that the homeostatic regulation of sleep develops early in human infants.

1990-01-01

In order to evaluate disturbances of the respiratory control in the first year of life in children with a statistically enhanced risk of SIDS, substance P-like immunoreactivity (SPLI) in plasma and mean apnoea duration (MA) were examined. 4 groups of infants were investigated: Controls, full-term infants with anamnestic SIDS-risk factors, preterm infants with additional risk factors and preterm infants without such factors. Infants aged from -4(corrected age) to 63 weeks. SPLI in plasma was determined by a specific, homologous radioimmunoassay. The SPLI-level was significantly higher in controls (n = 41; means +/- SE = 36.37 +/- 4.86 pg/ml) than in preterm infants without (n = 21; 25.41 +/- 5.54 pg/ml) or with additional anamnestic risk factors (n = 111; 25.89 +/- 3.09 pg/ml). SPLI was higher in full-term SIDS-risk infants (n = 150; 30.73 +/- 2.35 pg/ml) than in the preterm groups. There is a significant age dependence in the groups full-term SIDS-risk infants and preterm infants with additional risk factors. During maturation the SPLI-level in plasma rises in these groups from lower values. The MA-values were determined by means of a daytime polygraphy. There is an age dependence of the MA-values during active sleep in full-term SIDS-risk infants and in preterm infants with additional anamnestic risk factors. In the age group 4-17 weeks (peak of SIDS frequency) in active sleep the MA-values were significantly higher in all 3 risk groups than in the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of the present study was to investigate the impact of gastro-oesophageal acid reflux on sleep in neonates and, reciprocally, the influence of wakefulness (W) and sleep stages on the characteristics of the reflux (including the retrograde bolus migration of oesophageal acid contents). The pH and multichannel intraluminal impedance were measured during nocturnal polysomnography in 25 infants hospitalised for suspicion of gastro-oesophageal reflux. Two groups were constituted according to whether or not the infants displayed gastro-oesophageal reflux (i.e. a reflux group and a control group). There were no differences between the reflux and control groups in terms of sleep duration, sleep structure and sleep state change frequency. Vigilance states significantly influenced the gastro-oesophageal reflux pattern: the occurrence of gastro-oesophageal reflux episodes was greater during W (59 ± 32%) and active sleep (AS; 35 ± 30%) than during quiet sleep (QS; 6 ± 11%), whereas the mean duration of gastro-oesophageal reflux episodes was higher in QS than in W and AS. The percentage of retrograde bolus migrations of distal oesophageal acid content was significantly higher in AS (62 ± 26%) than in W (42 ± 26%) and QS (4.5 ± 9%). In neonates, gastro-oesophageal reflux occurred more frequently during W, whereas the physiological changes associated with sleep state increase the physiopathological impact of the gastro-oesophageal reflux. The duration of oesophagus-acid contact was greater during sleep; AS facilitated the retrograde migration of oesophageal acid content, and QS was characterised by the risk of prolonged acid mucosal contact. © 2011 European Sleep Research Society.

Sleep. 5: Driving and automobile crashes in patients with obstructive sleep apnoea/hypopnoea syndrome.

Driving is a complex task involving distinct cognitive, perceptual, motor, and decision making skills. After placing the vehicle on the road, the driver must constantly survey the ever changing roadway environment to keep the vehicle in the lane and moving at an appropriate safe speed. This surveillance involves two distinct visual tasks: estimating and responding to the oncoming curvature and controlling lane position. Driving is therefore a divided attention task involving speed and lane control as well as monitoring. To do this in a safe manner requires careful attention and alertness which can be problematic for patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS) or other sleep disorders.

Caring for an ill child at home gives the family the chance to be together in a familiar environment. However, this involves several nocturnal sleep disturbances, such as frequent awakenings and bad sleep quality, which may affect parents' ability to take care of the child and themselves. The aim of this study was to describe parents' perceptions of circumstances influencing their own sleep when living with a child enrolled in hospital-based home care (HBHC) services. This is a phenomenographical study with an inductive, exploratory design. Fifteen parents (11 mothers and 4 fathers) with children enrolled in HBHC services were interviewed. Data were analyzed to discover content-related categories describing differences in ways parents experienced sleep when caring for their children receiving HBHC. Four descriptive categories were detected: sleep influences mood and mood influences sleep; support influences safeness and safeness influences sleep; the child's needs influence routines and routines influence sleep; and "me time" influences sleep. Sleep does not affect only the parents' well-being but also the child's care. Symptoms of stress may limit the parents' capacity to meet the child's needs. Support, me time, and physical activity were perceived as essential sources for recovery and sleep. It is important for nurses to acknowledge parental sleep in the child's nursing care plan and help the parents perform self-care to promote sleep and maintain life, health, and well-being.

This study sought to assess the influence of prone positioning on the stress of newborn premature infants through the measurement of the salivary cortisol concentration and the evaluation of physiological and behavioral responses before and after changes in body positioning. Saliva samples were collected from newborn infants at two different times: the first (corresponding to the baseline) after a period of 40 minutes during which the infants were not subjected to any manipulation and were placed in the lateral or supine position, and the second 30 minutes after placement in the prone position. Variables including heart rate, respiratory rate, peripheral oxygen saturation, and the Brazelton sleep score were recorded before, during, and at the end of the period in the prone position. The sample comprised 16 newborn premature infants (56.3% male) with a gestational age between 26 and 36 weeks, postnatal age between 1 and 33 days, birth weight of 935 to 3,050g, and weight at the time of intervention of 870 to 2,890g. During the intervention, six participants breathed room air, while the remainder received oxygen therapy. The median salivary cortisol concentration was lower in the prone position compared to baseline (0.13 versus 0.20; p=0.003), as was the median Brazelton sleep score (p=0.02). The average respiratory rate was lower after the intervention (54.88±7.15 versus 60±7.59; p=0.0004). The remainder of the investigated variables did not exhibit significant variation. Prone positioning significantly reduced the salivary cortisol level, respiratory rate, and Brazelton sleep score, suggesting a correlation between prone positioning and reduction of stress in preterm infants.

Obstructive sleep apnea syndrome (OSAS) has been reported among children aged 3-6 years. Adenotonsillar hypertrophy is the most common cause of OSAS. The upper airway obstruction results in repeated obstructive apneas and hypopneas, associated with oxygen desaturations and sleep fragmentation. OSAS in children is associated with higher respiratory morbidity as well as significant clinical consequences, mainly neurocognitive and behavioral problems, impaired growth and cardiac dysfunction. The objectives of the present study were to determine the clinical and sleep characteristics of OSAS in children younger than 2 years, and to evaluate morbidity and health care utilization of infants with OSAS. This retrospective study included 35 children younger than 2 years of age, referred for polysomnography because of suspected OSAS. The controL group included healthy children, matched by age, gender and pediatrician. A total of 33 infants were diagnosed with OSAS. Mean apnea/hypopnea index [AHI) was 18.7 +/- 18.1 events/ hour [range 1.3-90.2]. In 10 infants a pattern of intermittent hypoxemia was observed. Infants with OSAS demonstrated a higher number of primary care clinic visits (20.8 +/- 14 vs. 12.1 +/- 6.6, P < 0.02). A higher percentage of children with OSAS visited the emergency room (60.6% vs. 32.2%, P < 0.03), and was hospitalized (36.3% vs. 12.9%, P < 0.03). Duration of hospitalization was also higher in the OSAS group [23.2 +/- 14.1% vs. 3 +/- 2.1%, P < 0.05). The number of drug prescriptions was higher among the study group [25.9 +/- 21.8% vs. 13.6 +/- 10.1, P < 0.03). Thirteen patients underwent adenoidectomy with or without tonsillectomy, resulting in improvement of AHI, decreasing from 26.4 +/- 24 before to 3.6 +/- 4.5 events per hour after surgery (p < 0.01). OSAS can be found in infants younger than 2 years of age. OSAS at this young age is characterized by a higher morbidity in comparison to healthy children. Early diagnosis and treatment may prevent morbidity in young children with OSAS.

Anticipatory guidance around the management of sleep and crying problems in early infancy has been shown to improve both infant behaviour and parent symptoms of postnatal depression. Digital technology offers platforms for making such programs widely available in a cost-efficient manner. However, it remains unclear who accesses online parenting advice and in particular, whether the parents who would most benefit are represented amongst users. It is also unknown whether the uptake of online programs can be improved by health professional recommendations, or whether parents require additional prompts and reminders to use the program. In this study we aim to: (1) determine whether weekly email prompts increase engagement with and use of a brief online program about infant sleeping and crying, (2) determine whether encouragement from a maternal and child health nurse promotes greater engagement with and use of the program, (3) examine who uses a brief online program about infant sleeping and crying; and, (4) examine the psychosocial characteristics of participants. This study is a randomised, parallel group, superiority trial, with all participating primary carers of infants aged 2 to 12 weeks, receiving access to the online program. Two modes of recruitment will be compared: recruitment via an online notice published on a non-commercial, highly credible and evidence-based website for parents and carers and via the parent's Maternal and Child Health nurse. After baseline assessment, parents will be randomised to one of two support conditions: online program alone or online program plus weekly email prompts. Follow up data will be collected at 4 months of infant age. Results from this trial will indicate whether involvement from a health professional, and/or ongoing email contact is necessary to engage parents in a brief online intervention, and promote parental use of strategies suggested within the program. Results of this trial will inform the development of recruitment and engagement strategies for other online interventions. Australian New Zealand Clinical Trials Registry: ACTRN12613001098729.

Infantile colic, cry-fuss and sleep problems are transient in the initial months of life, but they contribute to maternal depression, parenting stress and family mental health problems. In this randomized clinical trial, we aimed to explore the efficacy of massage therapy compared to rocking in reducing infantile colic symptoms including duration and number of cries, sleep duration and severity of infant colic. This was a single blind RCT study with a one-week follow-up. One hundred colicky infants aged younger than 12 weeks old were randomly assigned into massage and rocking groups. Infants in the massage group received a massage for 15-20 minutes once during a day and once at night before sleeping for a week. In the control group, mothers rocked their infants gently for 5-25 minutes when the symptoms of colic appeared. Parents recorded the details of the colic symptoms in a diary every day. A GEE approach was applied to explore the effect of the intervention. Efficiency of massage therapy was significantly higher than rocking. At the end of the study, the mean number of daily cries was 4.26±1.40 in the massage and 6.9±2.14 the rocking groups (p<0.01). The mean of the severity score was 1.39±0.19 less in the massage group (p<0.01). Moreover, the mean differences of massage and rocking groups were -0.82±0.20 hour (p<0.01) and 0.72±0.35 (p= 0.04) in the duration of cries and duration of sleep, respectively. Massaging significantly improved colic symptoms during a one-week intervention for all outcomes. In addition, significant differences were found between the intervention and control groups in favor of massaging. Therefore, massage therapy is more effective than rocking for treating infant colic symptoms.

The Safe Passage Study, conducted by the Prenatal Alcohol in SIDS and Stillbirth Network, is investigating contributions of prenatal alcohol exposure to foetal and infant demise. This current report presents physiological data from full-term infants with no prenatal exposure to alcohol or maternal smoking. Data are from 666 infants from the Northern Plains (North and South Dakota) and South Africa. A standardised protocol assessed cardiorespiratory function during baseline and head-up tilts shortly after birth and at one month of age. Analyses revealed significant increases in heart rate and decreases in BP from the newborn to one-month time period as well as diminished heart rate responses to head-up tilt in one-month-old infants. The Safe Passage Study was successful in characterising physiology in a large number of infants at sites known to have elevated risks for SIDS. Results demonstrate that even with low prenatal adverse exposures, there are significant changes in cardiorespiratory function as infants enter the window of increased risk for SIDS. ©2017 Foundation Acta Paediatrica.

1986-01-01

Three to four hour polygraphic sleep studies were carried out in 10 infants, five with upper respiratory infection and five with metabolic alkalosis secondary to vomiting during and after recovery from illness. During upper respiratory infection, the main abnormality detected was brief (greater than 3 less than 6 seconds) or prolonged (greater than 6 seconds) attacks of obstructive apnoea. Other indices of apnoea were similar to recovery data. Gross body movements were also increased. In infants with metabolic alkalosis indices of central apnoea were significantly increased when compared with recovery or case control data. Prolonged (greater than 15 seconds) attacks of central apnoea and obstructive apnoea (greater than 6 seconds) were only observed during illness. Gross body movements and periodic breathing were also increased. These findings suggest that the functional consequences of apparently 'mild' illnesses in young infants may be greater than is generally suspected and perhaps relevant to mechanism(s) of death in sudden infant death syndrome.

Mechanical analysis of infant carrying in hominoids

PubMed Central

2007-01-01

In all higher nonhuman primates, species survival depends upon safe carrying of infants clinging to body hair of adults. In this work, measurements of mechanical properties of ape hair (gibbon, orangutan, and gorilla) are presented, focusing on constraints for safe infant carrying. Results of hair tensile properties are shown to be species-dependent. Analysis of the mechanics of the mounting position, typical of heavier infant carrying among African apes, shows that both clinging and friction are necessary to carry heavy infants. As a consequence, a required relationship between infant weight, hair–hair friction coefficient, and body angle exists. The hair–hair friction coefficient is measured using natural ape skin samples, and dependence on load and humidity is analyzed. Numerical evaluation of the equilibrium constraint is in agreement with the knuckle-walking quadruped position of African apes. Bipedality is clearly incompatible with the usual clinging and mounting pattern of infant carrying, requiring a revision of models of hominization in relation to the divergence between apes and hominins. These results suggest that safe carrying of heavy infants justify the emergence of biped form of locomotion. Ways to test this possibility are foreseen here. PMID:18030438

Influence of supine sleep positioning on early motor milestone acquisition.

Majnemer, Annette; Barr, Ronald G

2005-06-01

This study aimed to determine whether supine sleep-positioned infants have delayed motor skills at age 4 and 6 months, and if delays are associated with decreased exposure to prone position. One 4 and one 6-month-old sample of healthy infants born at term were recruited. Motor assessments included the Peabody Developmental Motor Scale (PDMS) and Alberta Infant Motor Scale (AIMS). Parents completed an infant behavior diary for 3 consecutive days. Seventy-one 4-month-old infants were assessed (38 males; mean age 4.4 mo, standard deviation [SD] 0.2). Mean motor scores were close to normative standards (AIMS 47.7, SD 19.6; PDMS gross motor quotient [GMQ] 96.3, SD 6.5; PDMS fine motor quotient [FMQ] 99.2, SD 4.8). No infant scored below cut-off values used to identify motor delay. Milestones less likely to be achieved included extended arm support in prone, hands to feet in supine, and sitting with arm support. Exposure to 'tummy time' while awake was correlated with AIMS scores (r = 0.38, p < 0.01). F i fty 6-month-old infants were assessed (21 males; mean age 6.4 mo, SD 0.4). Mean scores were shifted down for all scales, and as much as 1 SD for PDMS (AIMS 44.5, SD 21.6; PDMS GMQ 85.7, SD 7.6; PDMS FMQ 88.9, SD 9.0). Only 22% of 6-month-olds could sit without arm support versus 50% expected in a normative sample. Remarkably, 22% of our sample exhibited gross motor delays (quotient <78). Tummy time (awake) was significantly associated with the AIMS (r = 0.64) and PDMS GMQ (r = 0.55) and FMQ (r = 0.33) quotients, even after adjusting for confounders. Typically developing infants who were sleep-positioned in supine had delayed motor development by age 6 months, and this was significantly associated with limited exposure to awake prone positioning. This has important implications for interpreting motor assessments of infants at risk and for preventing inappropriate referrals.

Can telemetry data obviate the need for sleep studies in Pierre Robin Sequence?

PubMed

Aaronson, Nicole Leigh; Jabbour, Noel

2017-09-01

This study looks to correlate telemetry data gathered on patients with Pierre Robin Sequence (PRS) with sleep study data. Strong correlation might allow obstructive sleep apnea (OSA) to be reasonably predicted without the need for sleep study. Charts from forty-six infants with PRS who presented to our children's hospital between 2005 and 2015 and received a polysomnogram (PSG) prior to surgical intervention were retrospectively reviewed. Correlations and scatterplots were used to compare average daily oxygen nadir, overall oxygen nadir, and average number of daily desaturations from telemetry data with apnea-hypopnea index (AHI) and oxygen nadir on sleep study. Results were also categorized into groups of AHI ≥ or <10 and oxygen nadir ≥ or <80% for chi-squared analysis. Our data did not show significant correlations between telemetry data and sleep study data. Patients with O2 nadir below 80% on telemetry were not more likely to have an O2 nadir below 80% on sleep study. Patients with an average O2 nadir below 80% did show some correlation with having an AHI greater than 10 on sleep study but this relationship did not reach significance. Of 22 patients who did not have any desaturations on telemetry below 80%, 16 (73%) had an AHI >10 on sleep study. In the workup of infants with PRS, the index of suspicion is high for OSA. In our series, telemetry data was not useful in ruling out severe OSA. Thus our data do not support forgoing sleep study in patients with PRS and concern for OSA despite normal telemetry patterns.

Anderson, Kirstie N; Smith, Ian E; Shneerson, John M

2006-06-01

Sleep-related rhythmic movements (head banging or body rocking) are extremely common in normal infants and young children, but less than 5% of children over the age of 5 years old exhibit these stereotyped motor behaviors. They characteristically occur during drowsiness or sleep onset rather than in deep sleep or rapid eye movement (REM) sleep. We present a 27-year-old man with typical rhythmic movement disorder that had persisted into adult life and was restricted to REM sleep. This man is the oldest subject with this presentation reported to date and highlights the importance of recognizing this nocturnal movement disorder when it does occur in adults.

School nurses can address existing gaps in school-age sleep research.

2013-06-01

Sleep has been linked to a host of physical, behavioral, and emotional outcomes, and research has documented that youth across the globe are experiencing inadequate sleep. Despite this knowledge, however, very little research has been conducted on school-age children; much of the extant research has focused on infants, toddlers, preschoolers, adolescents, and adults. School-age children exhibit increasing independence around health-related behaviors, which provide health professionals the opportunity to educate and promote healthy sleep behaviors. This commentary extends previous research reviews by identifying the current gaps in sleep research, highlighting future directions needed in sleep research, and explaining why school nurses are best suited to address this growing public health issue.

Association between sudden infant death syndrome and diphtheria-tetanus-pertussis immunisation: an ecological study.

Sudden infant death syndrome (SIDS) continues to be one of the main causes of infant mortality in the United States. The objective of this study was to analyse the association between diphtheria-tetanus-pertussis (DTP) immunisation and SIDS over time. The Centers for Disease Control and Prevention provided the number of cases of SIDS and live births per year (1968-2009), allowing the calculation of SIDS mortality rates. Immunisation coverage was based on (1) the United States Immunization Survey (1968-1985), (2) the National Health Interview Survey (1991-1993), and (3) the National Immunization Survey (1994-2009). We used sleep position data from the National Infant Sleep Position Survey. To determine the time points at which significant changes occurred and to estimate the annual percentage change in mortality rates, we performed joinpoint regression analyses. We fitted a Poisson regression model to determine the association between SIDS mortality rates and DTP immunisation coverage (1975-2009). SIDS mortality rates increased significantly from 1968 to 1971 (+27% annually), from 1971 to 1974 (+47%), and from 1974 to 1979 (+3%). They decreased from 1979 to 1991 (-1%) and from 1991 to 2001 (-8%). After 2001, mortality rates remained constant. DTP immunisation coverage was inversely associated with SIDS mortality rates. We observed an incidence rate ratio of 0.92 (95% confidence interval: 0.87 to 0.97) per 10% increase in DTP immunisation coverage after adjusting for infant sleep position. Increased DTP immunisation coverage is associated with decreased SIDS mortality. Current recommendations on timely DTP immunisation should be emphasised to prevent not only specific infectious diseases but also potentially SIDS.

Effects of cigarette smoke exposure on nicotinic acetylcholine receptor subunits {alpha}7 and {beta}2 in the sudden infant death syndrome (SIDS) brainstem

It is postulated that nicotine, as the main neurotoxic constituent of cigarette smoke, influences SIDS risk through effects on nicotinic acetylcholine receptors (nAChRs) in brainstem nuclei that control respiration and arousal. This study compared {alpha}7 and {beta}2 nAChR subunit expression in eight nuclei of the caudal and rostral medulla and seven nuclei of the pons between SIDS (n = 46) and non-SIDS infants (n = 14). Evaluation for associations with known SIDS risk factors included comparison according to whether infants had a history of exposure to cigarette smoke in the home, and stratification for sleep position and gender. Compared tomore » non-SIDS infants, SIDS infants had significantly decreased {alpha}7 in the caudal nucleus of the solitary tract (cNTS), gracile and cuneate nuclei, with decreased {beta}2 in the cNTS and increased {beta}2 in the facial. When considering only the SIDS cohort: 1-cigarette smoke exposure was associated with increased {alpha}7 in the vestibular nucleus and increased {beta}2 in the rostral dorsal motor nucleus of the vagus, rNTS and Cuneate, 2-there was a gender interaction for {alpha}7 in the gracile and cuneate, and {beta}2 in the cNTS and rostral arcuate nucleus, and 3-there was no effect of sleep position on {alpha}7, but prone sleep was associated with decreased {beta}2 in three nuclei of the pons. In conclusion, SIDS infants demonstrate differences in expression of {alpha}7 and {beta}2 nAChRs within brainstem nuclei that control respiration and arousal, which is independent on prior history of cigarette smoke exposure, especially for the NTS, with additional differences for smoke exposure ({beta}2), gender ({alpha}7 and {beta}2) and sleep position ({beta}2) evident. -- Highlights: Black-Right-Pointing-Pointer The 'normal' response to smoke exposure is decreased {alpha}7 and {beta}2 in certain nuclei. Black-Right-Pointing-Pointer SIDS infants have decreased {alpha}7 in cNTS, Grac and Cun. Black-Right-Pointing-Pointer SIDS infants have decreased {beta}2 in cNTS and increased {beta}2 in facial. Black-Right-Pointing-Pointer The NTS is more sensitive to both {alpha}7 and {beta}2 regulation in SIDS. Black-Right-Pointing-Pointer Smoke exposure amongst SIDS induces a different response; increased {alpha}7 and {beta}2.« less

Delta and theta power spectra of night sleep EEG are higher in breast-feeding mothers than in non-pregnant women.

The power spectra of night sleep EEGs of 12 breast-feeding 9-13 week postpartum mothers were analyzed and compared with those of 12 non-pregnant women. The power spectra in the delta and theta frequency range during NREM sleep for breast-feeding mothers were significantly higher than those for non-pregnant women. In addition, the all-night sleep patterns of the mothers were classified into two groups - interrupted sleep due to taking care of their infants and non-interrupted sleep - in order to observe the influence of partial sleep deprivation. The power spectra in the delta and theta frequency range were not significantly different between them. This result suggests that increased delta and theta power spectra during postpartum sleep do not result from partial sleep deprivation. The role of prolactin in breast-feeding mothers' sleep is also discussed.

The central aim of this study was to expand a limited body of knowledge on the complex relationship between breast-feeding, co-sleeping, and somatic complaints in early childhood. An opportunity sample of 98 parents from the general population with children aged 18 to 60 months consented to participate in the study. Each parent completed a series of questionnaires measuring somatic complaints, sleep problems, co-sleeping, breast-feeding, and demographic factors. Findings indicated that co-sleeping was associated with increased somatic complaints and that breast-feeding associated with decreased somatic complaints. Co-sleeping also was found to be associated with an increase in sleep problems. Boys demonstrated significantly higher levels of sleep problems than did girls. These findings highlight the relationship between co-sleeping during early childhood, which could have implications for prevention, treatment, and intervention regarding somatic complaints and sleep problems in early childhood. © 2016 Michigan Association for Infant Mental Health.

The neurological examination of critically ill neonates is largely limited to reflexive behavior. The exam often ignores sleep-wake physiology that may reflect brain integrity and influence long-term outcomes. We assessed whether polysomnography and concurrent cerebral near-infrared spectroscopy (NIRS) might improve prediction of 18-month neurodevelopmental outcomes. Term newborns with suspected seizures underwent standardized neurologic examinations to generate Thompson scores and had 12-hour bedside polysomnography with concurrent cerebral NIRS. For each infant, the distribution of sleep-wake stages and electroencephalogram delta power were computed. NIRS-derived fractional tissue oxygen extraction (FTOE) was calculated across sleep-wake stages. At age 18-22 months, surviving participants were evaluated with Bayley Scales of Infant Development (Bayley-III), 3rd edition. Twenty-nine participants completed Bayley-III. Increased newborn time in quiet sleep predicted worse 18-month cognitive and motor scores (robust regression models, adjusted r2 = 0.22, p = .007, and 0.27, .004, respectively). Decreased 0.5-2 Hz electroencephalograph (EEG) power during quiet sleep predicted worse 18-month language and motor scores (adjusted r2 = 0.25, p = .0005, and 0.33, .001, respectively). Predictive values remained significant after adjustment for neonatal Thompson scores or exposure to phenobarbital. Similarly, an attenuated difference in FTOE, between neonatal wakefulness and quiet sleep, predicted worse 18-month cognitive, language, and motor scores in adjusted analyses (each p < .05). These prospective, longitudinal data suggest that inefficient neonatal sleep-as quantified by increased time in quiet sleep, lower electroencephalogram delta power during that stage, and muted differences in FTOE between quiet sleep and wakefulness-may improve prediction of adverse long-term outcomes for newborns with neurological dysfunction. © Sleep Research Society 2017.

2016-10-01

The Regional Infant and Child Mortality Review Committee serves 10 counties in southeastern South Dakota and aims to use its reviews to prevent future loss of life during childhood. In 2015, the committee reviewed 24 deaths (compared to 32 cases in 2013 and 25 cases in 2014). Consistent with observations made in previous years, in 2015 all infants (n=7) who died during sleep did so with risks present in the sleep environment. Progress in decreasing these infant deaths in the region is not being observed, and in fact, may even be deteriorating. Two children died subsequent to a motor vehicle crash and neither were wearing a seat belt. The committee was pleased, however, to note that there were no childhood fatalities associated with teenaged drivers. One teen suicide in 2015 marked a decrease in the number observed in 2013 and 2014, but represents an ongoing concern about the safety of emotionally volatile adolescents. Further, one child homicide occurred in the region in 2015 reflecting the fragility of young in the presence of stressed and unstable home environments. The report provides the committee's recommendation for community action that could prevent future deaths of infants and children. Copyright© South Dakota State Medical Association.

Childhood Health and Educational Outcomes Associated With Maternal Sleep Apnea: A Population Record-Linkage Study.

Sleep apnea in pregnancy is known to adversely affect birth outcomes. Whether in utero exposure to maternal sleep apnea is associated with long-term childhood consequences is unclear. Population-based longitudinal study of singleton infants born during 2002-2012 was conducted using linked birth, hospital, death, developmental, and educational records from New South Wales, Australia. Maternal sleep apnea during pregnancy was identified from hospital records. Outcomes were mortality and hospitalizations up to age 6, developmental vulnerability in the first year of school (aged 5-6 years), and performance on standardized tests in the third year of school (aged 7-9 years). Cox proportional hazards and modified Poisson regression models were used to calculate hazard and risk ratios for outcomes in children exposed to maternal apnea compared with those not exposed. Two hundred nine of 626188 singleton infants were exposed to maternal sleep apnea. Maternal apnea was not significantly associated with mortality (Fisher's exact p = .48), developmental vulnerability (adjusted RR 1.29; 95% CI 0.75-2.21), special needs status (1.58; 0.61-4.07), or low numeracy test scores (1.03; 0.63-1.67) but was associated with low reading test scores (1.55; 1.08-2.23). Maternal apnea significantly increased hospitalizations in the first year of life (adjusted HR 1.81; 95% CI 1.40-2.34) and between the first and sixth birthdays (1.41; 1.14-1.75). This is partly due to admissions for suspected pediatric sleep apnea. Maternal sleep apnea during pregnancy is associated with poorer childhood health. Its impact on developmental and cognitive outcomes warrants further investigation. © Sleep Research Society 2017. Published by Oxford University Press on behalf of the Sleep Research Society.

Osborn, David A; Jeffery, Heather E; Cole, Michael J

2010-10-06

Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. To assess the effectiveness and safety of using a sedative compared to a non-opiate control for NAS due to withdrawal from opiates, and to determine which type of sedative is most effective and safe. This update included searches of the Cochrane Central Register of Controlled Trials (Issue 1, 2010), MEDLINE 1966 to April 2010 and abstracts of conference proceedings. Trials enrolling infants with NAS born to mothers with an opiate dependence with > 80% follow-up and using random or quasi-random allocation to sedative or control. Control could include another sedative or non-pharmacological treatment. Each author assessed study quality and extracted data independently. Seven studies enrolling 385 patients were included. There were substantial methodological concerns for most studies including the use of quasi-random allocation methods and sizeable, largely unexplained differences in reported numbers allocated to each group.One study reported phenobarbitone compared to supportive care alone did not reduce treatment failure or time to regain birthweight, but resulted in a significant reduction in duration of supportive care (MD -162.1 min/day, 95% CI -249.2, -75.1). Comparing phenobarbitone to diazepam, meta-analysis of two studies found phenobarbitone resulted in a significant reduction in treatment failure (typical RR 0.39, 95% CI 0.24, 0.62). Comparing phenobarbitone with chlorpromazine, one study reported no significant difference in treatment failure.In infants treated with an opiate, one study reported addition of clonidine resulted in no significant difference in treatment failure, seizures or mortality. In infants treated with an opiate, one study reported addition of phenobarbitone significantly reduced the proportion of time infants had a high abstinence severity score, duration of hospitalisation and maximal daily dose of opiate. Infants with NAS due to opiate withdrawal should receive initial treatment with an opiate. Where a sedative is used, phenobarbitone should be used in preference to diazepam. In infants treated with an opiate, the addition of phenobarbitone or clonidine may reduce withdrawal severity. Further studies are needed to determine the role of sedatives in infants with NAS due to opiate withdrawal and the safety and efficacy of adding phenobarbitone or clonidine in infants treated with an opiate for NAS.

Skin-to-skin contact shows benefits in the relationship developed between a mother and her premature infant. In the skin-to-skin session, face-to-face exchanges are impossible in vertical infant positioning. We therefore undertook an observational, prospective, single-center study using kangaroo "supported diagonal flexion" (SDF) positioning. The first aim was to evaluate the safety of kangaroo SDF positioning compared to the usual vertical positioning. The second aim was to evaluate SDF positioning on early communication between the mother and her infant and to improve their well-being. Fifteen mothers and their very premature infants (birth 26<32 weeks' gestation) were assigned to one of the two kangaroo positioning modes, either the current vertical positioning (n=7) or SDF positioning (n=8). Physiological variables and critical events were recorded before, during, and after ten successive skin-to-skin contact sessions. The first and last sessions were videotaped to allow later behavioral measurements. Mothers' risk for depression and feelings about the way they experienced communication with their infant were assessed through questionnaires. In terms of the infant's physiology, no negative effects were associated with SDF positioning in comparison with the usual vertical positioning. SDF positioning led to fewer disorganized gestures, negative vocalizations, and drowsiness, in favor of more deep sleep. SDF led to more mother-infant eye-to-eye contact as well as maternal vocalizations, smiles, and caressing, although these differences did not reach significance. The score for the risk of postnatal depression decreased significantly between the first and the last session in the SDF group, whereas it did not change in the vertical positioning group. These results support the idea that the kangaroo SDF positioning technique is physiologically safe, has obvious immediate benefits on mothers' infant-directed communicative behaviors, and respects the baby's naturally flexed and asymmetrical tonic neck posture. It is an innovative, inexpensive, easy-to-use technique in daily practice, by all healthcare professionals working in a neonatal intensive care unit. These data suggest that the current kangaroo positioning technique could be improved. More studies are needed to confirm the benefits and safety of the kangaroo SDF positioning in larger groups of preterm infants. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Tracking the connectivity of the developing brain from infancy through childhood is an area of increasing research interest, and fNIRS provides an ideal method for studying the infant brain as it is compact, safe and robust to motion. However, data analysis methods for fNIRS are still underdeveloped compared to those available for fMRI. Dynamic causal modelling (DCM) is an advanced connectivity technique developed for fMRI data, that aims to estimate the coupling between brain regions and how this might be modulated by changes in experimental conditions. DCM has recently been applied to adult fNIRS, but not to infants. The present paper provides a proof-of-principle for the application of this method to infant fNIRS data and a demonstration of the robustness of this method using a simultaneously recorded fMRI-fNIRS single case study, thereby allowing the use of this technique in future infant studies. fMRI and fNIRS were simultaneously recorded from a 6-month-old sleeping infant, who was presented with auditory stimuli in a block design. Both fMRI and fNIRS data were preprocessed using SPM, and analysed using a general linear model approach. The main challenges that adapting DCM for fNIRS infant data posed included: (i) the import of the structural image of the participant for spatial pre-processing, (ii) the spatial registration of the optodes on the structural image of the infant, (iii) calculation of an accurate 3-layer segmentation of the structural image, (iv) creation of a high-density mesh as well as (v) the estimation of the NIRS optical sensitivity functions. To assess our results, we compared the values obtained for variational Free Energy (F), Bayesian Model Selection (BMS) and Bayesian Model Average (BMA) with the same set of possible models applied to both the fMRI and fNIRS datasets. We found high correspondence in F, BMS, and BMA between fMRI and fNIRS data, therefore showing for the first time high reliability of DCM applied to infant fNIRS data. This work opens new avenues for future research on effective connectivity in infancy by contributing a data analysis pipeline and guidance for applying DCM to infant fNIRS data.

Relationship Between Child and Maternal Sleep: A Developmental and Cross-Cultural Comparison.

2015-08-01

The aim of this study was to assess the relationship between young children's sleep and maternal sleep from both a developmental and a cross-cultural perspective. Mothers of 10,085 young children completed the Brief Infant/Child Sleep Questionnaire and the Pittsburgh Sleep Quality Index. Overall, there were significant relationships between maternal and child sleep for bedtime, waketime, number of night wakings, and total nighttime sleep time across ages and cultures, although these relationships were stronger with younger children than preschool-aged children. Mothers report that their child's sleep pattern significantly impacts their sleep and daytime function, and they do not feel confident in managing their child's sleep pattern. Thus, interventions to improve children's sleep and develop good sleep habits, especially in early childhood, are likely to improve the quality of life of the whole family. © The Author 2015.

Physiological adaptation to high altitude hypoxia may be impaired in Andeans with significant European ancestry. The respiratory 'burden' of sleep may challenge adaptation, leading to relative nocturnal hypoxia. Developmental aspects of sleep-related breathing in high-altitude native children have not previously been reported. We aimed to determine the influence of development on diurnal-nocturnal oxyhemoglobin differences in children living at high altitude. This was a cross-sectional, observational study. Seventy-five healthy Bolivian children aged 6 mo to 17 y, native to low altitude (500 m), moderate high altitude (2,500 m), and high altitude (3,700 m) were recruited. Daytime resting pulse oximetry was compared to overnight recordings using Masimo radical oximeters. Genetic ancestry was determined from DNA samples. Children had mixed European/Amerindian ancestry, with no significant differences between altitudes. Sixty-two participants had ≥ 5 h of nocturnal, artifact-free data. As predicted, diurnal mean oxyhemoglobin saturation decreased across altitudes (infants and children, both P < 0.001), with lowest diurnal values at high altitude in infants. At high altitude, there was a greater drop in nocturnal mean oxyhemoglobin saturation (infants, P < 0.001; children, P = 0.039) and an increase in variability (all P ≤ 0.001) compared to low altitude. Importantly, diurnal to nocturnal altitude differences diminished (P = 0.036), from infancy to childhood, with no further change during adolescence. Physiological adaptation to high-altitude living in native Andeans is unlikely to compensate for the significant differences we observed between diurnal and nocturnal oxyhemoglobin saturation, most marked in infancy. This vulnerability to sleep-related hypoxia in early childhood has potential lifespan implications. Future studies should characterize the sleep- related respiratory physiology underpinning our observations. © 2016 Associated Professional Sleep Societies, LLC.

In Search of a Safe Natural Sleep Aid.

PubMed

Rao, Theertham P; Ozeki, Motoko; Juneja, Lekh R

2015-01-01

Sleep deprivation is associated with an elevated risk of various diseases and leads to a poor quality of life and negative socioeconomic consequences. Sleep inducers such as drugs and herbal medicines may often lead to dependence and other side effects. L-Theanine (γ-glutamylethylamide), an amino acid naturally found abundant in tea leaves, has anxiolytic effects via the induction of α brain waves without additive and other side effects associated with conventional sleep inducers. Anxiolysis is required for the initiation of high-quality sleep. In this study, we review the mechanism(s), safety, and efficacy of L-theanine. Collectively, sleep studies based on an actigraph, the obstructive sleep apnea (OSA) sleep inventory questionnaire, wakeup after sleep onset (WASO) and automatic nervous system (ANS) assessment, sympathetic and parasympathetic nerve activities, and a pediatric sleep questionnaire (PSQ) suggest that the administration of 200 mg of L-theanine before bed may support improved sleep quality not by sedation but through anxiolysis. Because L-theanine does not induce daytime drowsiness, it may be useful at any time of the day. The no observable adverse effect level (NOAEL) for the oral administration of L-theanine was determined to be above 2000 mg/kg bw/day. KEY TEACHING POINTS: Sleep deprivation-associated morbidity is an increasing public health concern posing a substantial socioeconomic burden. Chronic sleep disorders may seriously affect quality of life and may be etiological factors in a number of chronic diseases such as depression, obesity, diabetes, and cardiovascular diseases. Most sleep inducers are sedatives and are often associated with addiction and other side effects. L-Theanine promotes relaxation without drowsiness. Unlike conventional sleep inducers, L-theanine is not a sedative but promotes good quality of sleep through anxiolysis. This review suggests that L-theanine is a safe natural sleep aid.

The purpose of this study was to evaluate the effectiveness of foot reflexology on fatigue, sleep and pain. A systematic review and meta-analysis were conducted. Electronic database and manual searches were conducted on all published studies reporting the effects of foot reflexology on fatigue, sleep, and pain. Forty four studies were eligible including 15 studies associated with fatigue, 18 with sleep, and 11 with pain. The effects of foot reflexology were analyzed using Comprehensive Meta-Analysis Version 2.0. The homogeneity and the fail-safe N were calculated. Moreover, a funnel plot was used to assess publication bias. The effects on fatigue, sleep, and pain were not homogeneous and ranged from 0.63 to 5.29, 0.01 to 3.22, and 0.43 to 2.67, respectively. The weighted averages for fatigue, sleep, and pain were 1.43, 1.19, and 1.35, respectively. No publication bias was detected as evaluated by fail-safe N. Foot reflexology had a larger effect on fatigue and sleep and a smaller effect on pain. This meta-analysis indicates that foot reflexology is a useful nursing intervention to relieve fatigue and to promote sleep. Further studies are needed to evaluate the effects of foot reflexology on outcome variables other than fatigue, sleep and pain.

Curiosity's Autonomous Surface Safing Behavior Design

Neilson, Tracy A.; Manning, Robert M.

The safing routines on all robotic deep-space vehicles are designed to put the vehicle in a power and thermally safe configuration, enabling communication with the mission operators on Earth. Achieving this goal is made a little more difficult on Curiosity because the power requirements for the core avionics and the telecommunication equipment exceed the capability of the single power source, the Multi-Mission Radioisotope Thermoelectric Generator. This drove the system design to create an operational mode, called "sleep mode", where the vehicle turns off most of the loads in order to charge the two Li-ion batteries. The system must keep the vehicle safe from over-heat and under-heat conditions, battery cell failures, under-voltage conditions, and clock failures, both while the computer is running and while the system is sleeping. The other goal of a safing routine is to communicate. On most spacecraft, this simply involves turning on the receiver and transmitter continuously. For Curiosity, Earth is above the horizon only a part of the day for direct communication to the Earth, and the orbiter overpass opportunities only occur a few times a day. The design must robustly place the Rover in a communicable condition at the correct time. This paper discusses Curiosity's autonomous safing behavior and describes how the vehicle remains power and thermally safe while sleeping, as well as a description of how the Rover communicates with the orbiters and Earth at specific times.

Perceived neighborhood safety and sleep quality: a global analysis of six countries.

Hill, Terrence D; Trinh, Ha Ngoc; Wen, Ming; Hale, Lauren

2016-02-01

Building on previous North American and European studies of neighborhood context and sleep quality, we tested whether several self-reported sleep outcomes (sleep duration, insomnia symptoms, sleepiness, lethargy, and overall sleep quality) vary according to the level of perceived neighborhood safety in six countries: Mexico, Ghana, South Africa, India, China, and Russia. Using data (n = 39,590) from Wave I of the World Health Organization's Longitudinal Study on Global Ageing and Adult Health (2007-2010), we estimated a series of multinomial and binary logistic regression equations to model each sleep outcome within each country. Taken together, our results show that respondents who feel safe from crime and violence in their neighborhoods tend to exhibit more favorable sleep outcomes than respondents who feel less safe. This general pattern is especially pronounced in China and Russia, moderately evident in Mexico, Ghana, and South Africa, and sporadic in India. Perceptions of neighborhood safety are strongly associated with insomnia symptoms and poor sleep quality (past 30 days), moderately associated with sleepiness, lethargy, and poor sleep quality (past 2 days), and inconsistently associated with sleep duration (past two days). We show that perceived neighborhood safety is associated with more favorable self-reported sleep outcomes in six understudied countries. Additional research is needed to replicate our findings using longitudinal data, more reliable neighborhood measures, and more direct measures of sleep quality in these and other regions of the world.

Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive. We examined the relationship between maternal sleep duration and vital exhaustion in the first six months of pregnancy and spontaneous (non-medically indicated) preterm birth among 479 Peruvian women who delivered a preterm singleton infant (<37 weeks gestation) and 480 term controls who delivered a singleton infant at term (≥37 weeks gestation). Maternal nightly sleep and reports of vital exhaustion were ascertained through in-person interviews. Spontaneous preterm birth cases were further categorized as those following either spontaneous preterm labor or preterm premature rupture of membranes. In addition, cases were categorized as very (<32 weeks), moderate (32-33 weeks), and late (34- <37 weeks) preterm birth for additional analyses. Logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). After adjusting for confounders, we found that short sleep duration (≤6 hours) was significantly associated with preterm birth (aOR = 1.56; 95% CI 1.11-2.19) compared to 7-8 hours of sleep. Vital exhaustion was also associated with increased odds of preterm birth (aOR = 2.41; 95% CI 1.79-3.23) compared to no exhaustion (Ptrend <0.001). These associations remained significant for spontaneous preterm labor and preterm premature rupture of membranes. We also found evidence of joint effects of sleep duration and vital exhaustion on the odds of spontaneous preterm birth. The results of this case-control study suggest maternal sleep duration, particularly short sleep duration, and vital exhaustion may be risk factors for spontaneous preterm birth. These findings call for increased clinical attention to maternal sleep and the study of potential intervention strategies to improve sleep in early pregnancy with the aim of decreasing risk of preterm birth.

2008-12-01

The aetiology of infantile hypertrophic pyloric stenosis (IHPS) has not been fully elucidated. Since the 1990s, a sharp decline in IHPS has been reported in various countries. Recent research from Sweden reported a correlation between falling rates of IHPS and of sudden infant death syndrome (SIDS). This was attributed to a reduction in the number of infants sleeping in the prone position following the "Back to Sleep" campaign. To describe the changing epidemiology of IHPS in Scotland, to examine the relationship between IHPS and SIDS rates and to examine trends in other factors that may explain the observed reduction in IHPS incidence. Incidence rates of IHPS and SIDS were derived from routine data and their relationship analysed. Trends in mean maternal age, maternal smoking, mean birth weight and breastfeeding rates were also examined. The whole of Scotland between 1981 and 2004. IHPS incidence fell from 4.4 to 1.4 per 1000 live births in Scotland between 1981 and 2004. Rates were consistently higher in males, although the overall incidence patterns in males and females were similar. Rates showed a positive relationship with deprivation. The fall in the incidence of IHPS preceded the fall in SIDS by 2 years and the incidence of SIDS displayed less variability than that of IHPS. Significant temporal trends were also observed in other maternal and infant characteristics. There has been a marked reduction in Scotland's IHPS incidence, but this is unlikely to be a consequence of a change in infant sleeping position.

Cot Death: History of an Iatrogenic Disaster.

PubMed

Obladen, Michael

2018-01-01

Since antiquity, cot death has been explained as accidental suffocation, overlaying, or smothering. Parents were blamed for neglect or drunkenness. A cage called arcuccio was invented around 1570 to protect the sleeping infant. Up to the 19th century, accidents were registered as natural causes of death. From 1830, accidental suffocation became unacceptable for physicians and legislators, and "natural" explanations for the catastrophe were sought, with parents being consoled rather than blamed. Two assumed causes had serious consequences: thymus hyperplasia was irradiated, causing thyroid cancer, and the concept of central apnea was widely accepted, which led to home monitors and distracted from epidemiological evidence. Prone sleeping originated in the 1930s and from 1944, it was associated with cot death. However, from the 1960s, many authors recommended prone sleeping for infants, and many countries adopted the advice. A worldwide epidemic followed, peaking at 2‰ in England and Wales and 5‰ in New Zealand in the 1980s. Although epidemiological evidence was available by 1970, the first intervention was initiated in the Netherlands in 1989. Cot death disappeared almost entirely wherever prone sleeping was avoided. This strongly supports the assumption that prone sleeping has the greatest influence on the disorder, and that the epidemic resulted from wrong advice. © 2017 S. Karger AG, Basel.

Spectral-temporal EEG dynamics of speech discrimination processing in infants during sleep.

PubMed

Gilley, Phillip M; Uhler, Kristin; Watson, Kaylee; Yoshinaga-Itano, Christine

2017-03-22

Oddball paradigms are frequently used to study auditory discrimination by comparing event-related potential (ERP) responses from a standard, high probability sound and to a deviant, low probability sound. Previous research has established that such paradigms, such as the mismatch response or mismatch negativity, are useful for examining auditory processes in young children and infants across various sleep and attention states. The extent to which oddball ERP responses may reflect subtle discrimination effects, such as speech discrimination, is largely unknown, especially in infants that have not yet acquired speech and language. Mismatch responses for three contrasts (non-speech, vowel, and consonant) were computed as a spectral-temporal probability function in 24 infants, and analyzed at the group level by a modified multidimensional scaling. Immediately following an onset gamma response (30-50 Hz), the emergence of a beta oscillation (12-30 Hz) was temporally coupled with a lower frequency theta oscillation (2-8 Hz). The spectral-temporal probability of this coupling effect relative to a subsequent theta modulation corresponds with discrimination difficulty for non-speech, vowel, and consonant contrast features. The theta modulation effect suggests that unexpected sounds are encoded as a probabilistic measure of surprise. These results support the notion that auditory discrimination is driven by the development of brain networks for predictive processing, and can be measured in infants during sleep. The results presented here have implications for the interpretation of discrimination as a probabilistic process, and may provide a basis for the development of single-subject and single-trial classification in a clinically useful context. An infant's brain is processing information about the environment and performing computations, even during sleep. These computations reflect subtle differences in acoustic feature processing that are necessary for language-learning. Results from this study suggest that brain responses to deviant sounds in an oddball paradigm follow a cascade of oscillatory modulations. This cascade begins with a gamma response that later emerges as a beta synchronization, which is temporally coupled with a theta modulation, and followed by a second, subsequent theta modulation. The difference in frequency and timing of the theta modulations appears to reflect a measure of surprise. These insights into the neurophysiological mechanisms of auditory discrimination provide a basis for exploring the clinically utility of the MMR TF and other auditory oddball responses.

Infant attachment and toddlers' sleep assessed by maternal reports and actigraphy: different measurement methods yield different relations.

To investigate relations between children's attachment and sleep, using objective and subjective sleep measures. Secondarily, to identify the most accurate actigraphy algorithm for toddlers. 55 mother-child dyads took part in the Strange Situation Procedure (18 months) to assess attachment. At 2 years, children wore an Actiwatch for a 72-hr period, and their mothers completed a sleep diary. The high sensitivity (80) and smoothed actigraphy algorithms provided the most plausible sleep data. Maternal diaries yielded longer estimated sleep duration and shorter wake duration at night and showed poor agreement with actigraphy. More resistant attachment behavior was not associated with actigraphy-assessed sleep, but was associated with longer nocturnal wake duration as estimated by mothers, and with a reduced actigraphy-diary discrepancy. Mothers of children with resistant attachment are more aware of their child's nocturnal awakenings. Researchers and clinicians should select the best sleep measurement method for their specific needs.

Spinal anesthesia for inguinal hernia repair in infants: a feasible and safe method even in emergency cases.

Inguinal hernia repair is the most frequently performed surgical procedure in infants and children. Especially in premature infants, prevalence reaches up to 30% in coincidence with high rates of incarceration during the first year of life. These infants carry an increased risk of complications due to general anesthesia. Thus, spinal anesthesia is a topic of growing interest for this group of patients. We hypothesized that spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants even at high risk and cases of incarceration. Between 2003 and 2013, we operated 100 infants younger than 6 months with inguinal hernia. Clinical data were collected prospectively and retrospectively analyzed. Patients were divided into two groups depending on anesthesia procedure (spinal anesthesia, Group 1 vs. general anesthesia, Group 2). Spinal anesthesia was performed in 69 infants, and 31 infants were operated in general anesthesia, respectively. In 7 of these 31 infants, general anesthesia was chosen because of lumbar puncture failure. Infants operated in spinal anesthesia were significantly smaller (54 ± 4 vs. 57 ± 4 cm; p = 0.001), had a lower body weight (4,047 ± 1,002 vs. 5,327 ± 1,376 g; p < 0.001) and higher rate of prematurity (26 vs. 4%; p = 0.017) compared to those operated in general anesthesia. No complications related to surgery or to anesthesia were found in both groups. The number of relevant preexisting diseases was higher in Group 1 (11 vs. 3%; p = 0.54). Seven of eight emergent incarcerated hernia repairs were performed in spinal anesthesia (p = 0.429). Spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants, especially in high-risk premature infants and in cases of hernia incarceration.

Both short sleep duration and sleep-disordered breathing (SDB) are associated with poor neurocognitive development. However, the co-contributions of short sleep duration and SDB on neurodevelopment in pre-school children are relatively unknown. We assessed both sleep duration and SDB by quarterly questionnaire from three months to two years of age among Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort participants. Group-based modeling determined trajectories of total, daytime, and nighttime sleep duration and SDB. Linear regression was used to assess the impact of sleep duration and SDB trajectories on cognitive (primary outcome) and language (secondary) development at two years of age as assessed by the Bayley Scale of Infant Development (BSID-III) (mean 100; standard deviation of 15). Of the 822 CHILD Edmonton participants, 703 (86%) were still enrolled at two years of age with 593 having BSID-III data at two years of age. Trajectory analysis identified four total sleep durations phenotypes [short sleepers (17.9%), decline to short sleepers (21.1%), intermediate sleepers (36.9%) and long sleepers (24.1%)]. Compared to children with intermediate sleep durations, short sleepers had a 5.2-point lower cognitive development score at two years of age [standard error (SE) 1.7; p = 0.002]. Nocturnal sleep duration, compared to daytime sleep duration had the greatest effect on cognitive development. We also identified three SDB symptom trajectories [early-onset SDB (15.7%), late-onset SDB (14.2%), and persistent SDB (5.3%)] and 79.5% of children had no SDB symptoms. Children with persistent SDB also had a 5.3-point lower language score (SE 2.7; p = 0.05) compared to children with no SDB. SDB trajectories were not associated with cognitive development. In a population-representative birth cohort study, both short sleep duration and SDB were associated with adverse neurodevelopment at two years of age. Children with short nighttime sleep duration had lowered cognitive and language scores and children with persistent SDB also had lower language scores. Copyright © 2018 Elsevier B.V.

Achondroplasia is the most common form of dwarfism. Respiratory failure is responsible for most deaths among these children and is often related to cervicomedullary compression (CMC). We present our experience with early cervicomedullary decompression in infants with achondroplasia. Data was retrospectively collected for infants with achondroplasia who underwent CMC decompression between 1998 and 2013. Data included presurgical and postsurgical neurological examinations, MRI scans, and sleep study results. Ten infants were included. Ages at surgery were 4 to 23 months (12.5 ± 6.88 months). All infants displayed neurological findings prior to surgery, although often subtle. All infants underwent a foramen magnum opening with a wide C1 laminectomy. Following surgery, seven patients (70 %) demonstrated improved neurological status, and one displayed neurological deterioration. Seven patients demonstrated improved sleep quality 1 year after surgery. These patients had a good or improved neurological status following surgery. Preoperative radiological findings included abnormal hyperintense T2 changes in all children (improved following surgery in six children), brainstem distortion in four children (improved in all), and diminished cerebrospinal fluid (CSF) spaces at the level of the foramen magnum in eight children (improved in seven). One child with extensive preoperative T2 changes accompanied by neurological and respiratory decline, deteriorated following surgery, and remains chronically ventilated. Infants with achondroplasia are prone to neurological and respiratory symptoms. We believe that early diagnosis and early surgery for decompression of the foramen magnum and C1 lamina can alleviate respiratory symptoms, improve neurological status, and perhaps prevent sudden infant death in this population.

This study examined the longitudinal association between marital instability and child sleep problems at ages 9 and 18 months in 357 families with a genetically unrelated infant adopted at birth. This design eliminates shared genes as an explanation for similarities between parent and child. Structural equation modeling indicated that T1 marital instability predicted T2 child sleep problems, but T1 child sleep problems did not predict T2 marital instability. This pattern of results was replicated when models were estimated separately for mothers and children and for fathers and children. Thus, even after controlling for stability in sleep problems and marital instability and eliminating shared genetic influences on associations using a longitudinal adoption design, marital instability prospectively predicts early childhood sleep patterns.

Ateah, Christine A

2013-01-01

The purpose of this pilot project was to determine first-time expectant parents' perceptions of a parent education intervention, their education needs, and preferred sources and modes of such education. The intervention was carried out during the last class of a public health prenatal education series. A total of 31 first-time expectant parents participated and included both women (N = 16) and men (N = 15; mean, 29 years). The intervention was an in-person session on the topics of a safe sleeping environment, shaken baby syndrome, physical punishment risks and positive parenting, and expected development and safety. Participants completed the Infant Safety Education Project Questionnaire after the intervention. Overall, most participants in this study found the content useful, planned to use it in caring for their infant, and indicated that this information should be shared with all expectant parents. Findings support a larger scale study to determine parent education needs of expectant parents and the development, implementation, and evaluation of programming. Pediatric nurse practitioners and other primary care practitioners should be aware of the education needs of expectant parents and be prepared to provide anticipatory guidance and resources as appropriate.

Risks and Benefits of Swaddling Healthy Infants: An Integrative Review.

PubMed

Nelson, Antonia M

Swaddling has been practiced since antiquity; however, there is controversy about its safety. The purpose of this review is to update and build upon previous reviews and synthesize evidence on risks and benefits of swaddling in healthy-term, near-term, or older infants. MEDLINE (1960-May 13, 2016) and CINAHL (1963-May 13, 2016) searches were conducted, relevant articles retrieved, and citation lists reviewed for other references. A table summarizes study details. Selected older references and supporting literature are integrated into the synthesis to provide context. Swaddling calms infants and promotes sleep, but it is equally or less effective than other nonpharmacological methods in managing pain. There may be a slight risk for sudden infant death syndrome associated with supine swaddling, although the impact of confounding variables is unclear. Early skin-to-skin contact supports early breastfeeding, but swaddling does not have a negative impact on breastfeeding long term. Swaddling tightly around the hips is strongly associated with developmental dysplasia of the hip. More research is needed on the impact of swaddling on pain in term infants, infant vital signs, arousal thresholds, and a possible association between swaddling, vitamin D deficiency, and acute lower respiratory tract infection. The number of studies was small, with few randomized control trials, and researchers used different definitions of swaddling. If a few precautions are taken, such as swaddling securely to minimize risk of unwrapping, avoiding overheating, placing infants to sleep supine, and discontinuing swaddling when infants first show signs of rolling over, swaddling presents minimal risk. Maternity and neonatal nurses should model swaddling practices based on the evidence and promote informed decision-making among infant caregivers.

Laughter elevates the levels of breast-milk melatonin.

PubMed

Kimata, Hajime

2007-06-01

Patients with atopic eczema (AE) often complain of sleep disturbance. Melatonin is involved in sleep, and the levels of blood melatonin in patients with AE are decreased in comparison to healthy subjects. However, the levels of breast-milk melatonin had only been reported in healthy subjects. Laughter increased natural killer cell activity in blood and free radical-scavenging capacity in saliva in healthy subjects. Thus, the effect of laughter on the levels of breast-milk melatonin was studied in mothers with AE. Moreover, the effect of feeding with breast milk after laughter on allergic responses in infants was studied. Forty-eight infants aged 5-6 months were enrolled. All of the infants had AE and were allergic to latex and house dust mite (HDM). Half (n=24) of the mothers of these infants were patients with AE, while another 24 mothers were healthy subjects. The mothers viewed either an 87-min humorous DVD (Modern Times, featuring Charlie Chaplin) or an 87-min nonhumorous weather information DVD at 2000 h. After viewing, breast milk was collected sequentially from 2200, 2400, 0200, 0400 to 0600 h. The levels of breast-milk melatonin were measured. In addition, skin wheal responses to HDM and histamine were studied in infants. Laughter caused by viewing a humorous DVD increased the levels of breast-milk melatonin in both mothers with AE and healthy mothers. In addition, allergic responses to latex and HDM of infants were reduced by feeding with breast milk after laughter of mothers with AE or of healthy mothers. Laughter increased the levels of breast-milk melatonin in both mothers with AE and healthy mothers, and feeding infants with increased levels of melatonin-containing milk reduced allergic responses in infants. Thus, laughter of mothers may be helpful in the treatment of infants with AE.

Infant Deaths and Injuries Associated with Wearable Blankets, Swaddle Wraps, and Swaddling

2014-01-01

Objective To assess risks involved in using wearable blankets, swaddle wraps, and swaddling. Study design Retrospective review of incidents reported to the Consumer Product Safety Commission in 2004–2012. Results 36 incidents involving wearable blankets and swaddle wraps were reviewed, including 10 deaths, 2 injuries, and 12 incidents without injury. The median age at death was 3.5 months; 80% of deaths were attributed to positional asphyxia related to prone sleeping. 70% had additional risk factors, usually soft bedding. Two injuries involved tooth extraction from the zipper. The 12 incidents without injury reported concern for strangulation/suffocation when the swaddle wrap became wrapped around the face/neck, and potential choking hazard when the zipper detached. All 12 incidents involving swaddling in ordinary blankets resulted in death. The median age was 2 months; 58% of deaths were attributed to positional asphyxia related to prone sleeping. 92% involved additional risk factors, most commonly soft bedding. Conclusions Reports of sudden unexpected death in swaddled infants are rare. Risks can be reduced by placing infants supine, and discontinuing swaddling as soon as an infant’s earliest attempts to roll are observed. Risks can be further reduced by removing soft bedding and bumper pads from the sleep environment. When using commercial swaddle wraps, fasteners must be securely attached. PMID:24507866

Teinonen, Tuomas; Tervaniemi, Mari; Huotilainen, Minna

2016-01-01

Statistical learning and the social contexts of language addressed to infants are hypothesized to play important roles in early language development. Previous behavioral work has found that the exaggerated prosodic contours of infant-directed speech (IDS) facilitate statistical learning in 8-month-old infants. Here we examined the neural processes involved in on-line statistical learning and investigated whether the use of IDS facilitates statistical learning in sleeping newborns. Event-related potentials (ERPs) were recorded while newborns were exposed to12 pseudo-words, six spoken with exaggerated pitch contours of IDS and six spoken without exaggerated pitch contours (ADS) in ten alternating blocks. We examined whether ERP amplitudes for syllable position within a pseudo-word (word-initial vs. word-medial vs. word-final, indicating statistical word learning) and speech register (ADS vs. IDS) would interact. The ADS and IDS registers elicited similar ERP patterns for syllable position in an early 0–100 ms component but elicited different ERP effects in both the polarity and topographical distribution at 200–400 ms and 450–650 ms. These results provide the first evidence that the exaggerated pitch contours of IDS result in differences in brain activity linked to on-line statistical learning in sleeping newborns. PMID:27617967

Subspecialty pediatric practice provides comprehensive medical care for a range of ages, from premature infants to children, and often includes adults with complex medical and surgical issues that warrant multidisciplinary care. Normal physiologic variations involving different body systems occur during sleep and these vary with age, stage of sleep, and underlying health conditions. This article is a concise review of the cardiovascular (CV) physiology and pathophysiology in children, sleep-disordered breathing (SDB) contributing to CV morbidity, congenital and acquired CV pathology resulting in SDB, and the relationship between SDB and CV morbidity in different clinical syndromes and systemic diseases in the expanded pediatric population.

The present paper reports on the influence of the Scud missile attacks during the Gulf War on the sleep of Israeli children. Two studies were performed. In the first, sleep habits and sleep disturbances of 61 (mean age 20 months) infants were assessed by questionnaires completed by their parents 5 months before the war and immediately after the end of the War. Comparison of pre- and post-war data revealed no major changes in sleep habits or in sleep quality. In the second study, sleep of 55 children was monitored at home by actigraphs during the last month of the War. All children were aroused during missile attacks, but returned to sleep immediately, with no evidence of carry-over effects once the 'all clear' sign was given. Comparison of sleep quality measures obtained during the War with those of age- and sex-matched children monitored a year before the war did not reveal any significant differences apart from the immediate response to the attack.

Mothers' online message board questions about parenting infants and toddlers.

Porter, Noriko; Ispa, Jean M

2013-03-01

To report a study conducted to explore childrearing concerns through an analysis of online parenting message boards managed by popular parenting magazines. Background.  Increasingly, mothers appear to be turning to the Web for childrearing advice and support. However, no previous studies have examined the childrearing concerns of mothers of infants and toddlers through the analysis of online message board postings. Ethnographic content analysis methods were used to analyse the online postings. A total of 120 messages posted in 2007 by mothers of 0-2 year olds on the websites of two best-selling parenting magazines in the United States were submitted to ethnographic content analysis. Each message pertained to one or more of six childrearing domains: Feeding/Eating, Sleep, Development, Discipline, Toilet-Training and Mother-Child Relationships. Questions and pleas for support were most prominently centred on feeding/eating and sleep issues. Mothers expressed concerns about when and how their children should begin to sleep and eat independently. In addition to the themes specific to particular domains, across-domain themes were identified involving mothers' parenting stress, questioning of advice from families/paediatricians and worries that children were not developing normally. Online forums have become a space where mothers can openly describe their own negative emotions towards parenting and ask questions or gain reassurance to resolve mixed messages about how one should rear infants and toddlers. Paediatric nurses should be aware that mothers are confused about conflicting messages, especially in the domains of sleeping and eating. Reviewing parenting message boards occasionally would give nurses continuing insight into common parenting concerns. © 2012 Blackwell Publishing Ltd.

Twenty-to-forty percent of women experience postpartum depressive symptoms, which can affect both the mother and infant. In preterm infants, daily skin-to-skin contact (SSC) between the mother and her infant has been shown to decrease maternal postpartum depressive symptoms. In full-term infants, only two studies investigated SSC effects on maternal depressive symptoms and found similar results. Research in preterm infants also showed that SSC improves other mental and physical health outcomes of the mother and the infant, and improves the quality of mother-infant relationship. This randomized controlled trial will investigate the effects of a SSC intervention on maternal postpartum depressive symptoms and additional outcomes in mothers and their full-term infants. Moreover, two potential underlying mechanisms for the relation between SSC and the maternal and infant outcomes will be examined, namely maternal oxytocin concentrations and infant intestinal microbiota. Design: A parallel-group randomized controlled trial. 116 mothers and their full-term infants. Mothers in the SSC condition will be requested to provide daily at least one continuous hour of SSC to their infant. The intervention starts immediately after birth and lasts for 5 weeks. Mothers in the control condition will not be requested to provide SSC. Maternal and infant outcomes will be measured at 2 weeks, 5 weeks, 12 weeks and 1 year after birth. maternal postpartum depressive symptoms. Secondary maternal outcomes: mental health (anxiety, stress, traumatic stress following child birth, sleep quality), physical health (physical recovery from the delivery, health, breastfeeding, physiological stress), mother-infant relationship (mother-infant bond, quality of maternal caregiving behavior). Secondary infant outcomes: behavior (fussing and crying, sleep quality), physical health (growth and health, physiological stress), general development (regulation capacities, social-emotional capacities, language, cognitive and motor capacities). Secondary underlying mechanisms: maternal oxytocin concentrations, infant intestinal microbiota. As a simple and cost-effective intervention, SSC may benefit both the mother and her full-term infant in the short-and long-term. Additionally, if SSC is shown to be effective in low-risk mother-infant dyads, then thought could be given to developing programs in high-risk samples and using SSC in a preventive manner.

Disparities in infant mortality and effective, equitable care: are infants suffering from benign neglect?

PubMed

Rowley, Diane L; Hogan, Vijaya

2012-04-01

Quality care for infant mortality disparity elimination requires services that improve health status at both the individual and the population level. We examine disparity reduction due to effective care and ask the following question: Has clinical care ameliorated factors that make some populations more likely to have higher rates of infant mortality compared with other populations? Disparities in postneonatal mortality due to birth defects have emerged for non-Hispanic black and Hispanic infants. Surfactant and antenatal steroid therapy have been accompanied by growing disparities in respiratory distress syndrome mortality for black infants. Progesterone therapy has not reduced early preterm birth, the major contributor to mortality disparities among non-Hispanic black and Puerto Rican infants. The Back to Sleep campaign has minimally reduced SIDS disparities among American Indian/Alaska Native infants, but it has not reduced disparities among non-Hispanic black infants. In general, clinical care is not equitable and contributes to increasing disparities.

Scholle, S; Zwacka, G; Scheidt, B; Glaser, S; Oehme, P; Rathsack, R

1989-01-01

The prospective study presented conducted to prevent SIDS (sudden infant death syndrome). One of the proposed hypotheses on SIDS postulates a brainstem abnormality in the neuroregulation of cardiorespiratory processes. Therefore we characterized cardiorespiratory control mechanisms by examining the neurotransmitter substance P in plasma and polysomnographic investigations. With respect to the probable multifactorial origin of SIDS we selected children firstly anamnestically by means of an epidemiologically evaluated pre-, peri- and postnatal risk score. We reported the results of 208 polysomnographically and biochemically examined children anamnestically selected from a group of 2500 neonates. Examinations were performed on infants aged 2-4 weeks up to 1 year. To characterize respiratory control, length and frequency of apnoeas were separately estimated by means of polysomnography in the sleep states active and quiet sleep. If there were polygraphic risk factors representing a disturbance of respiratory control, the children were prophylactically treated with aminophylline 3 x 3 mg/kg b.w. for 4 weeks. We found a significant age dependence both of the mean apnoea duration in active sleep and the substance P level in plasma in the SIDS-risk group but not in the controls. High mean apnoea duration was correlated with low substance P level in the first months of age in SIDS risk infants selected anamnestically. This may reflect a delayed maturation of respiratory control mechanisms. In this way the polysomnography and the investigation of the neuropeptide substance P may be useful for a screening method indicating wether the respiratory control mechanisms are mature or not.

To evaluate the impact of moderate noise on the sleep of very early preterm infants (VPI). Observational study of 26 VPI of 26-31 weeks' gestation, with prospective measurements of sound pressure level and concomitant video records. Sound peaks were identified and classified according to their signal-to-noise ratio (SNR) above background noise. Prechtl's arousal states during sound peaks were assessed by two observers blinded to the purpose of the study. Changes in sleep/arousal states following sound peaks were compared with spontaneous changes during randomly selected periods without sound peaks. We identified 598 isolated sound peaks (5 ≤ SNR < 10 decibel slow response A (dBA), n = 518; 10 ≤ SNR < 15 dBA, n = 80) during sleep. Awakenings were observed during 33.8% (95% CI, 24-43.7%) of exposures to sound peaks of 5-10 dBA SNR and 39.7% (95% CI, 26-53.3%) of exposures to sound peaks of SNR 10-15 dBA, but only 11.7% (95% CI, 6.2-17.1%) of control periods. The proportions of awakenings following sound peaks were higher than the proportions of arousals during control periods (p < 0.005). Moderate acoustic changes can disrupt the sleep of VPI, and efficient sound abatement measures are needed. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

MR might be well suited to obtain reproducible and accurate measures of fat tissues in infants. This study evaluates MR-measurements of adipose tissue in young infants in vitro and in vivo. MR images of ten phantoms simulating subcutaneous fat of an infant's torso were obtained using a 1.5T MR scanner with and without simulated breathing. Scans consisted of a cartesian water-suppression turbo spin echo (wsTSE) sequence, and a PROPELLER wsTSE sequence. Fat volume was quantified directly and by MR imaging using k-means clustering and threshold-based segmentation procedures to calculate accuracy in vitro. Whole body MR was obtained in sleeping young infants (average age 67±30 days). This study was approved by the local review board. All parents gave written informed consent. To obtain reproducibility in vivo, cartesian and PROPELLER wsTSE sequences were repeated in seven and four young infants, respectively. Overall, 21 repetitions were performed for the cartesian sequence and 13 repetitions for the PROPELLER sequence. In vitro accuracy errors depended on the chosen segmentation procedure, ranging from 5.4% to 76%, while the sequence showed no significant influence. Artificial breathing increased the minimal accuracy error to 9.1%. In vivo reproducibility errors for total fat volume of the sleeping infants ranged from 2.6% to 3.4%. Neither segmentation nor sequence significantly influenced reproducibility. With both cartesian and PROPELLER sequences an accurate and reproducible measure of body fat was achieved. Adequate segmentation was mandatory for high accuracy.

Background. Pacifier use decreases the risk of sudden infant death syndrome (SIDS). An emergency department (ED) visit may provide an opportunistic 'teachable moment' for parents. Objectives. To test the hypotheses (1) that caregivers were less familiar with the role of pacifiers in sudden infant death (SIDS) prevention than other recommendations, and (2) that an ED educational intervention would increase pacifier use in infants younger than six months, and (3) that otitis media would not occur more frequently in pacifier users. Methods. We did an intervention-group-only longitudinal study in a county hospital ED. We measured pacifier use infants and baseline knowledge of SIDs prevention recommendations in caregivers. We followed up three months later to determine pacifier use, and 12 months later to determine episodes of otitis media. Results. We analyzed data for 780 infants. Parents knew of advice against co-sleeping in 469/780 (60%), smoking in 660/776 (85%), and prone sleeping in 613/780 (79%). Only 268/777 (35%) knew the recommendation to offer a pacifier at bedtime. At enrollment 449/780 (58%) did not use a pacifier. Of 210/338 infants aged less than 6 months followed up 41/112 (37%) non-users had started using a pacifier at bedtime (NNT 3). Over the same period, 37/98 (38%) users had discontinued their pacifier. Otitis media did not differ between users and non-users at 12 months. Conclusion. Caregiver knowledge of the role of pacifiers in SIDS prevention was less than for other recommendations. Our educational intervention appeared to increase pacifier use. Pacifier use was not associated with increased otitis media.

Pacifiers are widely used in developed societies. They are used for soothing infants, reducing their stress and pain during procedures and to help them sleep. The use of pacifiers has been associated, however, with a shorter duration and exclusivity of breastfeeding, with higher rates of otitis media and dental problems, as well as a higher risk of accidents during infancy. Recent studies have also described a relationship between pacifier use and SIDS, especially when used during infant́s sleep. Other described benefits are analgesia and stimulation of non-nutritive sucking in preterm and term infants. There is, at present, wide debate and controversy on whether or not to recommend its use; thus it seems important for professionals and parents to be aware of the risks and benefits associated to its use, particularly related to breastfeeding. Due to the existing controversy of scientific findings, the Committee on Breastfeeding of the Spanish Paediatrics Society, publishes this review, trying to summarise present evidence with the objective of, after analysing scientific results and recommendations, making recommendations regarding the use of the pacifier in the breastfed infant.

The trend toward single-room neonatal intensive care units (NICUs) is increasing; however scientific evidence is, at this point, mostly anecdotal. This is a critical time to assess the impact of the single-room NICU on improving medical and neurobehavioral outcomes of the preterm infant. We have developed a theoretical model that may be useful in studying how the change from an open-bay NICU to a single-room NICU could affect infant medical and neurobehavioral outcome. The model identifies mediating factors that are likely to accompany the change to a single-room NICU. These mediating factors include family centered care, developmental care, parenting and family factors, staff behavior and attitudes, and medical practices. Medical outcomes that plan to be measured are sepsis, length of stay, gestational age at discharge, weight gain, illness severity, gestational age at enteral feeding, and necrotizing enterocolitis (NEC). Neurobehavioral outcomes include the NICU Network Neurobehavioral Scale (NNNS) scores, sleep state organization and sleep physiology, infant mother feeding interaction scores, and pain scores. Preliminary findings on the sample of 150 patients in the open-bay NICU showed a “baseline” of effects of family centered care, developmental care, parent satisfaction, maternal depression, and parenting stress on the neurobehavioral outcomes of the newborn. The single-room NICU has the potential to improve the neurobehavioral status of the infant at discharge. Neurobehavioral assessment can assist with early detection and therefore preventative intervention to maximize developmental outcome. We also present an epigenetic model of the potential effects of maternal care on improving infant neurobehavioral status. PMID:21255702

Sleep Patterns and Fatigue in New Mothers and Fathers

Gay, Caryl L.; Lee, Kathryn A.; Lee, Shih-Yu

2005-01-01

The purpose of this study was to describe the sleep patterns and fatigue of both mothers and fathers before and after childbirth. The authors used wrist actigraphy and questionnaires to estimate sleep and fatigue in 72 couples during their last month of pregnancy and 1st month postpartum. Both parents experienced more sleep disruption at night during the postpartum period as compared to the last month of pregnancy. Compared to fathers, with their stable 24-h sleep patterns over time, mothers had less sleep at night and more sleep during the day after the baby was born. Sleep patterns were also related to parents’work status and type of infant feeding. Both parents self-reported more sleep disturbance and fatigue during the 1st month postpartum than during pregnancy. Mothers reported more sleep disturbance than fathers, but there was no gender difference in ratings of fatigue. At both time points, fathers obtained less total sleep than mothers when sleep was objectively measured throughout the entire 24-h day. Further research is needed to determine the duration of sleep loss for both mothers and fathers, to evaluate the effect of disrupted sleep and sleep loss on psychosocial functioning and job performance, and to develop interventions for improving sleep patterns of new parents.

Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P < 0.05 and 42%, P < 0.0001). More postpartum (63%) than pregnant (40%) women reported dream-associated behaviors (P < 0.01), but neither group differed from null gravida women (56%). This was due to different distributions over groups of the behavior subtypes. Motor activity was present in twice as many postpartum (57%) as pregnant (24%) or null gravida (25%) women (all P < 0.0001). Expressing emotion was more prevalent among null gravida (56%) than postpartum women (27%) (P < 0.05) but was not different from pregnant women (37%). Speaking was equally prevalent among the 3 groups (12%-19%). Behaviors were associated with nightmares, dream anxiety and, among postpartum women, post-awakening anxiety (41%), confusion (51%), and a need to check on the infant (60%). Primiparas and multiparas differed in dream and nightmare recall but not in prevalence of dream-associated behaviors. Conclusion: The prevalent occurrence of pregnancy and postpartum infant dreams and associated behaviors may reflect the pervasive emotional influence of maternal concerns or changes instigated by severe sleep disruption, rapid eye movement sleep deprivation, and altered hormone levels.

Tryptophan can be metabolized via 5-hydroxytryptamine=serotonin to melatonin by a series of 4 enzymes in pineal body. Lack of serotonin in body fluid in the brain during daytime can lead to several psychiatric disorders, while shortage of plasma-melatonin at night can be related to sleep disorders. The Morning-Evening (M-E) questionnaire and the original questionnaire including questions on sleep habits, mental symptoms, and contents of meals were administered to 1055 infants aged 0-6 yrs, 751 students attending an elementary school, and 473 students attending junior high school in Kochi City (33 degrees N). The index of tryptophan taken at breakfast (Trp-Index) was calculated as tryptophan amount per one meal based on the tryptophan included in each 100 g of the foods and a standard amount of food per one meal. A significant positive-correlation between M-E scores and Trp-Index was not shown by relatively older students, aged 9-15 yrs (Pearson's test, r=0.044-0.123, p=0.071-0.505), whereas a significant positive correlation was shown by infants and young elementary school students aged 0-8 yrs (r=0.180, 0.258, p<0.001). The more frequently the infants had difficulty falling asleep at bedtime and waking up in the morning, the less the Trp-Indices taken at breakfast were (Kruskall-Wallis-test, p=0.027 for difficulty falling asleep; p=0.008 for difficulty waking up). The more frequently infants became angry even by a little trigger, or depressed, the lower (more evening-typed) the M-E scores were (Kruskal-Wallis test: p

Little information is available on the movement behaviours of infants, despite evidence that these are important for development. The release of new Australian 24-hour Movement Guidelines provides an opportunity to document the current state of movement behaviours in infants relative to these guidelines. The aim of this study was to report the prevalence of 4 month old Australian infants meeting the 24-hour Movement Guidelines, individually, and in combination, and to describe associations with individual characteristics. Maternal report baseline data from the Melbourne Infant Feeding, Activity and Nutrition Trial Program were used to determine prevalence of infants meeting physical activity (30 min of tummy time per day), sedentary behaviour (no more than 1 h at a time kept restrained; zero screen time), and sleep guidelines (14-17 h for 0-3 month olds or 12-16 h for 4-11 month olds). Prevalence of infants meeting combined guidelines was also described. The odds of meeting guidelines based on infant and family characteristics was determined. Data are reported for 455 infants with a mean age of 3.6 months (SD = 1.0). The proportion of infants meeting each of the guidelines was 29.7% for tummy time, 56.9% for kept restrained, 27.9% for screen time, 58.7% for sleep and 3.5% for the combined guidelines (i.e. meeting all four guidelines). A significantly higher proportion of girls than boys met the screen time guideline (32.5% versus 24.0%, p = 0.04) and the combined guidelines (5.7% versus 1.6%, p = 0.01). Few associations were observed between infant and family characteristics and proportion of infants meeting individual guidelines. Very few infants met all of the guidelines contained in the new Australian 24-hour Movement Guidelines suggesting there is much room for improvement in movement behaviours from early life. Fewer infants met the tummy time and screen time guidelines hence these appear to be the behaviours requiring most attention. Parents and others providing care to infants require support and strategies to assist them in adhering to the guidelines to ensure optimal health and development for the youngest in our population.

Sudden infant death syndrome (SIDS) involves failure of arousal to potentially life threatening events, including hypoxia, during sleep. While neuronal dysfunction and abnormalities in neurotransmitter systems within the medulla oblongata have been implicated, the specific pathways associated with autonomic and cardiorespiratory failure are unknown. The neuropeptide substance P (SP) and its tachykinin neurokinin-1 receptor (NK1R) have been shown to play an integral role in the modulation of homeostatic function in the medulla, including regulation of respiratory rhythm generation, integration of cardiovascular control, and modulation of the baroreceptor reflex and mediation of the chemoreceptor reflex in response to hypoxia. Abnormalities in SP neurotransmission may therefore result in autonomic dysfunction during sleep and contribute to SIDS deaths. [125I] Bolton Hunter SP autoradiography was used to map the distribution and density of the SP, NK1R to 13 specific nuclei intimately related to cardiorespiratory function and autonomic control in the human infant medulla of 55 SIDS and 21 control (non-SIDS) infants. Compared to controls, SIDS cases exhibited a differential, abnormal developmental profile of the SP/NK1R system in the medulla. Furthermore the study revealed significantly decreased NK1R binding within key medullary nuclei in SIDS cases, principally in the nucleus tractus solitarii (NTS) and all three subdivisions of the inferior portion of the olivo-cerebellar complex; the principal inferior olivary complex (PIO), medial accessory olive (MAO) and dorsal accessory olive (DAO). Altered NK1R binding was significantly influenced by prematurity and male sex, which may explain the increased risk of SIDS in premature and male infants. Abnormal NK1R binding in these medullary nuclei may contribute to the defective interaction of critical medullary mechanisms with cerebellar sites, resulting in an inability of a SIDS infant to illicit appropriate respiratory and motor responses to life threatening challenges during sleep. These observations support the concept that abnormalities in a multi-neurotransmitter network within key nuclei of the medullary homeostatic system may underlie the pathogenesis of a subset of SIDS cases.

Neurocognitive and behavioral impact of sleep disordered breathing in children.

Owens, Judith A

2009-05-01

The consequences of poor quality and/or inadequate sleep in children and adolescents have become a major public health concern, and one in which pediatric health care professionals have become increasingly involved. In particular, insufficient and/or fragmented sleep resulting from primary sleep disorders such as obstructive sleep apnea (OSA), often compounded by the presence of comorbid sleep disorders as well as by voluntary sleep curtailment related to lifestyle and environmental factors, has been implicated in a host of negative consequences. These range from metabolic dysfunction and increased cardiovascular morbidity to impairments in mood and academic performance. The following review will focus on what is currently known about the effects of sleep disordered breathing (SDB) specifically on neurobehavioral and neurocognitive function in children. Because of the scarcity of literature on the cognitive and behavioral impact of sleep disorders in infants and very young children, this review will target largely the preschool/school-aged child and adolescent populations. In addition, the focus will be on a review of the most recent literature, as a supplement to several excellent previous reviews on the topic. (c) 2009 Wiley-Liss, Inc.

Positional circulatory control in the sleeping infant and toddler: role of the inner ear and arterial pulse pressure.

Heart rate (HR) and arterial blood pressure (BP) are rapidly and reflexively adjusted as body position and the force/direction of gravity alters. Anomalies in these mechanisms may predispose to circulatory failure during sleep. We analysed the development of two key reflexes involved by undertaking a longitudinal (birth–1 year) comparison of instantaneous HR and BP changes evoked by abrupt upright, sideways or horizontal repositioning. Each manoeuvre triggered an identical rise in HR (tachycardia) followed by a slower rise in diastolic blood pressure (DBP)/systolic blood pressure (SBP) and variable pulse pressure (PP) change. We show that tachycardia is triggered by acceleration (vestibular) sensors located in the inner ear and slight changes in the pulsatile component of BP then signal to the arterial baroreceptors to reinforce or oppose these actions as needed. We also identified a PP anomaly in sleeping 1-year-olds of smokers that prematurely slows HR and is associated with mild positional hypotension. We conclude that positional circulatory compensation is initiated pre-emptively in a feed-forward manner and that feedback changes in vago-sympathetic drive to the heart (and perhaps blood vessels) by PP exert a slower but powerful modulating effect. An anomaly in either or both mechanisms may weaken positional compensation in some sleeping infants.

Eliminating medullary 5-HT neurons delays arousal and decreases the respiratory response to repeated episodes of hypoxia in neonatal rat pups

Arousal from sleep is a critical defense mechanism when infants are exposed to hypoxia, and an arousal deficit has been postulated as contributing to the etiology of the sudden infant death syndrome (SIDS). The brainstems of SIDS infants are deficient in serotonin (5-HT) and tryptophan hydroxylase (TPH) and have decreased binding to 5-HT receptors. This study explores a possible connection between medullary 5-HT neuronal activity and arousal from sleep in response to hypoxia. Medullary raphe 5-HT neurons were eliminated from neonatal rat pups with intracisterna magna (CM) injections of 5,7-dihydroxytryptamine (DHT) at P2-P3. Each pup was then exposed to four episodes of hypoxia during sleep at three developmental ages (P5, P15, and P25) to produce an arousal response. Arousal, heart rate, and respiratory rate responses of DHT-injected pups were compared with pups that received CM artificial cerebrospinal fluid (aCSF) and those that received DHT but did not have a significant reduction in medullary 5-HT neurons. During each hypoxia exposure, the time to arousal from the onset of hypoxia (latency) was measured together with continuous measurements of heart and respiratory rates, oxyhemoglobin saturation, and chamber oxygen concentration. DHT-injected pups with significant losses of medullary 5-HT neurons exhibited significantly longer arousal latencies and decreased respiratory rate responses to hypoxia compared with controls. These results support the hypothesis that in newborn and young rat pups, 5-HT neurons located in the medullary raphe contribute to the arousal response to hypoxia. Thus alterations medullary 5-HT mechanisms might contribute to an arousal deficit and contribute to death in SIDS infants. PMID:26702023

Infant and toddler crying, sleeping and feeding problems and trajectories of dysregulated behavior across childhood.

PubMed

Winsper, Catherine; Wolke, Dieter

Infant and toddler regulatory problems (RPs) including crying, sleeping and feeding, are a frequent concern for parents and have been associated with negative behavioral outcomes in early and middle childhood. Uncertain is whether infant and toddler RPs predict stable, trait-like dysregulated behavior across childhood. We addressed this gap in the literature using data from the Avon Longitudinal Study of Parents and Children (ALSPAC). RPs at 6, 15-18, & 24-30 months and childhood dysregulated behavior at 4, 7, 8, & 9.5 years were assessed using mother report. Latent Class Growth Analysis (LCGA) indicated that trajectories of childhood dysregulated behavior were stable over time. All single RPs (i.e., crying, sleeping & feeding problems) were significantly associated with childhood dysregulated behavior. For example, crying problems at 6 months after controlling for confounders (Odds Ratios; 95% Confidence Intervals): Moderate dysregulated behavior: OR = 1.50, 95% CI [1.09 to 2.06], high dysregulated behavior: OR = 2.13, 95% CI [1.49 to 3.05] and very high dysregulated behavior: OR = 2.85, 95% CI [1.64 to 4.94]. Multiple RPs were especially strongly associated with dysregulated behavior. For example, the RP composite at 15-18 months: 1 RP, very high dysregulated behavior: OR = 2.79, 95% CI [2.17 to 3.57], 2 RPs, very high dysregulated behavior: OR = 3.46, 95% CI [2.38 to 5.01], 3 RPs, very high dysregulated behavior: OR = 12.57, 95% CI [6.38 to 24.74]. These findings suggest that RPs in infants and toddlers predict stable dysregulated behavior trajectories across childhood. Interventions for early RPs could help prevent the development of chronic, highly dysregulated behavior.

Microbiome-Gut-Brain Axis: A Pathway for Improving Brainstem Serotonin Homeostasis and Successful Autoresuscitation in SIDS-A Novel Hypothesis.

Sudden infant death syndrome (SIDS) continues to be a major public health issue. Following its major decline since the "Back to Sleep" campaign, the incidence of SIDS has plateaued, with an annual incidence of about 1,500 SIDS-related deaths in the United States and thousands more throughout the world. The etiology of SIDS, the major cause of postneonatal mortality in the western world, is still poorly understood. Although sleeping in prone position is a major risk factor, SIDS continues to occur even in the supine sleeping position. The triple-risk model of Filiano and Kinney emphasizes the interaction between a susceptible infant during a critical developmental period and stressor/s in the pathogenesis of SIDS. Recent evidence ranges from dysregulated autonomic control to findings of altered neurochemistry, especially the serotonergic system that plays an important role in brainstem cardiorespiratory/thermoregulatory centers. Brainstem serotonin (5-HT) and tryptophan hydroxylase-2 (TPH-2) levels have been shown to be lower in SIDS, supporting the evidence that defects in the medullary serotonergic system play a significant role in SIDS. Pathogenic bacteria and their enterotoxins have been associated with SIDS, although no direct evidence has been established. We present a new hypothesis that the infant's gut microbiome, and/or its metabolites, by its direct effects on the gut enterochromaffin cells, stimulates the afferent gut vagal endings by releasing serotonin (paracrine effect), optimizing autoresuscitation by modulating brainstem 5-HT levels through the microbiome-gut-brain axis, thus playing a significant role in SIDS during the critical period of gut flora development and vulnerability to SIDS. The shared similarities between various risk factors for SIDS and their relationship with the infant gut microbiome support our hypothesis. Comprehensive gut-microbiome studies are required to test our hypothesis.

Purpose MR might be well suited to obtain reproducible and accurate measures of fat tissues in infants. This study evaluates MR-measurements of adipose tissue in young infants in vitro and in vivo. Material and Methods MR images of ten phantoms simulating subcutaneous fat of an infant’s torso were obtained using a 1.5T MR scanner with and without simulated breathing. Scans consisted of a cartesian water-suppression turbo spin echo (wsTSE) sequence, and a PROPELLER wsTSE sequence. Fat volume was quantified directly and by MR imaging using k-means clustering and threshold-based segmentation procedures to calculate accuracy in vitro. Whole body MR was obtained in sleeping young infants (average age 67±30 days). This study was approved by the local review board. All parents gave written informed consent. To obtain reproducibility in vivo, cartesian and PROPELLER wsTSE sequences were repeated in seven and four young infants, respectively. Overall, 21 repetitions were performed for the cartesian sequence and 13 repetitions for the PROPELLER sequence. Results In vitro accuracy errors depended on the chosen segmentation procedure, ranging from 5.4% to 76%, while the sequence showed no significant influence. Artificial breathing increased the minimal accuracy error to 9.1%. In vivo reproducibility errors for total fat volume of the sleeping infants ranged from 2.6% to 3.4%. Neither segmentation nor sequence significantly influenced reproducibility. Conclusion With both cartesian and PROPELLER sequences an accurate and reproducible measure of body fat was achieved. Adequate segmentation was mandatory for high accuracy. PMID:25706876

Stimulus type does not affect infant arousal response patterns.

Richardson, Heidi L; Walker, Adrian M; Horne, Rosemary S C

Previous studies have examined infant arousal responses to various arousal stimuli; however it is unclear whether the patterns of responses to different stimuli are comparable within subjects across early development. The aim of the study was to compare the effects of both respiratory and somatosensory stimulation on arousal processes in the same infants throughout the first 6 months of life. Ten healthy term infants were studied with daytime polysomnography at 2-4 weeks, 2-3 and 5-6 months. Infants were challenged with both hypoxia (15% O(2), balanced N(2)) and a pulsatile air-jet to the nostrils. Stimulus-induced sub-cortical activations (SCA) and cortical arousals (CA) were expressed as percentages of total arousals. Heart rate (HR) changes and electroencephalogram (EEG) desynchronization were also contrasted for the two stimuli. During active sleep (AS), there was no significant effect of stimulus type on proportions of CA at any of the ages studied. During quiet sleep (QS), hypoxia elicited higher CA proportions than the air-jet at 2-3 and 5-6 months (P < 0.01). Overall, HR responses associated with SCA and CA and the duration of EEG desynchronization during CA were similar for both stimuli. Mild hypoxia and nasal air-jet stimulation produce qualitatively similar patterns of arousal responses during the first 6 months of life, supporting the concept of a final common neural pathway of cortical activation. Quantitatively, full CA from QS is more likely with hypoxia, in keeping with it being a life-threatening stimulus. This study supports the nasal air-jet as an appropriate stimulus for assessing developmental patterns of infant arousal process.

Theoretically, any participating parameter in a non-linear system represents the dynamics of the whole system. Taken's time delay embedding theory provides the fundamental basis for allowing non-linear analysis to be performed on physiological, time-series data. In practice, only one measurable parameter is required to be measured to convey an accurate representation of the system dynamics. In this paper, the infant respiratory control system is represented using three variables-a digitally sampled respiratory inductive plethysmography waveform, and the derived parameters tidal volume and inter-breath interval time series data. For 14 healthy infants, these data streams were analysed using recurrence plot analysis across one night of sleep. The measured attractor size of these variables followed the same qualitative trends across the nights study. Results suggest that the attractor size measures of the derived IBI and tidal volume are representative surrogates for the raw respiratory waveform. The extent to which the relative attractor sizes of IBI and tidal volume remain constant through changing sleep state could potentially be used to quantify pathology, or maturation of breathing control.

Waking up too early - the consequences of preterm birth on sleep development.

Good quality sleep of sufficient duration is vital for optimal physiological function and our health. Sleep deprivation is associated with impaired neurocognitive function and emotional control, and increases the risk for cardiometabolic diseases, obesity and cancer. Sleep develops during fetal life with the emergence of a recognisable pattern of sleep states in the preterm fetus associated with the development, maturation, and connectivity within neural networks in the brain. Despite the physiological importance of sleep, surprisingly little is known about how sleep develops in individuals born preterm. Globally, an estimated 15 million babies are born preterm (<37 weeks gestation), and these babies are at significant risk of neural injury and impaired brain development. This review discusses how sleep develops during fetal and neonatal life, how preterm birth impacts on sleep development to adulthood, and the factors which may contribute to impaired brain and sleep development, leading to altered neurocognitive, behavioural and motor capabilities in the infant and child. Going forward, the challenge is to identify specific risk factors for impaired sleep development in preterm babies to allow for the design of interventions that will improve the quality and quantity of sleep throughout life.

EXTRAOCULAR MUSCLE ACTIVITY, RAPID EYE MOVEMENTS, AND THE DEVELOPMENT OF ACTIVE AND QUIET SLEEP

Rapid eye movements (REMs), traditionally measured using the electrooculogram (EOG), help to characterize active sleep in adults. In early infancy, however, they are not clearly expressed. Here we measure extraocular muscle activity in infant rats at 3 days of age (P3), P8, and P14–15 in order to assess the ontogeny of REMs and their relationship with other forms of sleep-related phasic activity. We find that the causal relationship between extraocular muscle twitches and REMs strengthens during the first two postnatal weeks, reflecting increased control of the extraocular muscles over eye movements. As early as P3, however, phasic bursts of extraocular muscle twitching occur in synchrony with twitching in other muscle groups, producing waves of phasic activity interspersed with brief periods of quiescence. Surprisingly, the tone of the extraocular muscles, invisible to standard EOG measures, fluctuates in synchrony with the tone of other muscle groups; focal electrical stimulation within the dorsolateral pontine tegmentum, an area that has been shown to contain wake-on neurons in P8 rats, results in the simultaneous activation of high tone in both nuchal and extraocular muscles. Finally, when state-dependent neocortical electroencephalographic activity was observed at P14, it had already integrated fully with sleep and wakefulness as defined using electromyographic criteria alone; this finding is not consistent with the notion that active sleep in infants at this age is “half-activated.” All together, these results indicate exquisite temporal organization of sleep soon after birth and highlight the possible functional implications of homologous activational states in striated muscle and neocortex.

Short and poor sleep have been associated with adverse health outcomes in adults, such as overweight/obesity and type 2 diabetes, especially among women. Women therefore represent an important target for interventions aimed at improving sleep and such interventions have been advocated to enhance maternal, fetal, and infant health. This systematic review will assess the efficacy or effectiveness of behavioral interventions aimed at promoting adequate sleep among women. The primary outcomes will be changes in sleep duration and/or sleep quality from baseline to post-intervention and to the last available follow-up measured either through self-reports or objectively. Secondary outcomes will be assessing the behavior change techniques that are responsible for the changes in sleep duration and quality among women. Behavioral interventions that are non-pharmacological and target either sleep directly or sleep hygiene behaviors will be included. Randomized controlled trials, quasi-experimental, and one-group pre-post studies will be included, but treated separately in the analyses, given that a limited number of studies on the topic of sleep is expected. MEDLINE/PubMed, PsycINFO, CINAHL, EMBASE, and Proquest Dissertations and Theses will be investigated. There will be no restriction on the year of publication of the articles, but we will include only the ones written in English or French. Two authors will independently assess articles for eligibility and will extract data using a standardized data extraction form that will have been previously pilot-tested. The quality of the studies will be assessed using the Effective Public Health Practice Project tool for quantitative study designs. The intervention procedures will be classified according to the latest validated taxonomy of behavior change techniques. If there is a sufficient number of studies (k > 5), a meta-analysis of the results will be performed with a random-effect model. If the heterogeneity is high (I 2  ≥ 75%), it will be investigated through sensitivity analyses and meta-regression. This review will provide valuable information to those interested in promoting adequate sleep among women and, hopefully, encourage additional research in this important field to promote maternal, fetal, and infant health. The study protocol was registered in PROSPERO in October 2016 (CRD42016049538).

Generally blood pressure (BP) should drop or dip by 10-20% during sleep. The phenomenon of nondipping BP during sleep has gained interest because of its association with various damaging effects to end-organs. This exploratory study examined nighttime nondipping BP, acculturative stress and quality of sleep in 30 Korean American women. Acculturative stress and sleep quality were measured using the Revised Social, Attitudinal, Familial, and Environmental Acculturative Stress Scale (R-SAFE) and the Pittsburg Sleep Quality Index (PSQI), respectively. Participants' BP was monitored over a 24-hour period. Participants were categorized as dippers and nondippers based on the drop in nocturnal systolic BP. Of the 30 women, 8 (26.7%) were nondippers. A shorter sleep duration and more disturbed sleep were associated with nondipping and, interestingly, less acculturative stress was also associated with nondipping BP. Our finding supports that sleep evaluation is needed in caring for individuals with nondipping BP.

Safe enough to sleep: sleep disruptions associated with trauma, posttraumatic stress, and anxiety in children and adolescents.

Sleep disturbance is an essential symptom of posttraumatic stress disorder, and recent evidence suggests that disrupted sleep may play an important role in the development of posttraumatic stress disorder following traumatic stress. The authors review several aspects of sleep as it relates to posttraumatic stress disorder. First, there is an association between traumatic stress and different components of disrupted sleep in children and adolescents. Second, sleep disruption appears to be a core feature of other pediatric anxiety disorders, and the authors consider if this preexisting sleep vulnerability may explain in part why preexisting anxiety disorders are a risk factor for developing posttraumatic stress disorder following a traumatic event. Third, the authors consider attachment theory and the social context of trauma and sleep disruption. This article concludes with a consideration of the therapeutic implications of these findings.

A secondary analysis of longitudinal and cohort studies was carried out to quantitatively investigate the motor activity pattern, recorded through actigraphy, during the first six hours of nocturnal sleep. The first study was of longitudinal nature. Ten healthy participants (four females) were monitored three times, at baseline (T1) when they were infants (mean age 7.10 ± 0.32 months), at the first follow-up examination (T2) around 4 months later (mean age 11.20 ± 0.63 months) and at the second follow-up (T3) around three years later, when they were preschoolers (mean age 4.68 ± 0.14 years). At T1, T2 and T3 each participant wore the actigraph Basic Mini-Motionlogger (Ambulatory Monitoring, Inc., Ardsley, NY, USA) over at least two consecutive nycthemeral cycles, with the aim to measure the mean hourly motor activity count. Seven- and 11-month-old infants had a higher level of motor activity over the night compared to preschoolers. Furthermore, motor activity increased as the night progressed, with a pronounced increment at both T1 and T2, while at T3 such an increase was less marked. The second study was cross-sectional and aimed to explore the motor activity pattern, using actigraphy, during the first six hours of nocturnal sleep in multiple-age healthy groups, from infancy to adulthood. We assigned participants to eight groups according to age: 20 (five females) aged around 10 months old (mean age 10.65 ± 0.67 months); 13 (nine females) aged around 4 years (mean age 4.38 ± 0.51 years); 21 (10 females) aged around 10 years (mean age 9.67 ± 0.91 years); 21 (nine females) aged around 20 years (mean age 19.33 ± 2.44 years); 20 (10 females) aged around 30 years (mean age 29.80 ± 1.99 years); 20 (15 females) aged around 40 years (mean age 40.70 ± 1.26 years); 20 (11 females) aged around 50 years (mean age 50.15 ± 2.80 years) and 20 (nine females) aged around 60 years (mean age 59.25 ± 3.23 years). The participants aged between 10 and 60 years wore the actigraph Basic Mini-Motionlogger over seven consecutive nycthemeral cycles (infants and preschoolers wore the actigraph over at least two consecutive nycthemeral cycles), with the aim to measure the mean hourly motor activity count. The results indicated a significantly higher motor activity count in 10-month-old infants compared to all the remaining age groups. Moreover, the pattern of motor activity of 10-month-old infants was different from that of all other groups, with the highest motor activity counts from the second to the sixth hour of sleep. Considered as a whole, the results of both studies converge regarding the high motor activity detected among infants, which could be explained by the presence of a maturational process that has not yet been fully completed at this stage of life. In both studies, only the motor activity of infants was above the cutoff level established for normal adults, highlighting the need to establish a specific cutoff value for infants.

To determine the feasibility and safety of respiratory muscle function testing in weak infants with a progressive neuromuscular disorder. Respiratory insufficiency is the major cause of morbidity and mortality in infants with spinal muscular atrophy type I (SMA-I). Tests of respiratory muscle strength, endurance, and breathing patterns can be performed safely in SMA-I infants. Useful data can be collected which parallels the clinical course of pulmonary function in SMA-I. An exploratory study of respiratory muscle function testing and breathing patterns in seven infants with SMA-I seen in our neuromuscular clinic. Measurements were made at initial study visit and, where possible, longitudinally over time. We measured maximal inspiratory (MIP) and transdiaphragmatic pressures, mean transdiaphragmatic pressure, airway occlusion pressure at 100 msec of inspiration, inspiratory and total respiratory cycle time, and aspects of relative thoracoabdominal motion using respiratory inductive plethysmography (RIP). The tension time index of the diaphragm and of the respiratory muscles, phase angle (Φ), phase relation during the total breath, and labored breathing index were calculated. Age at baseline study was 54-237 (median 131) days. Reliable data were obtained safely for MIP, phase angle, labored breathing index, and the invasive and non-invasive tension time indices, even in very weak infants. Data obtained corresponded to the clinical estimate of severity and predicted the need for respiratory support. The testing employed was both safe and feasible. Measurements of MIP and RIP are easily performed tests that are well tolerated and provide clinically useful information for infants with SMA-I. © 2014 Wiley Periodicals, Inc.

Infant massage is increasingly being used in the community with babies and their primary caregivers. Anecdotal reports suggest benefits for sleep, respiration and elimination, the reduction of colic and wind, and improved growth. Infant massage is also thought to reduce infant stress and promote positive parent-infant interaction. The aim of this review was to assess whether infant massage is effective in promoting infant physical and mental health in low-risk, population samples. Relevant studies were identified by searching the following electronic databases up to June 2011: CENTRAL; MEDLINE; EMBASE; CINAHL; PsycINFO; Maternity and Infant Care; LILACS; WorldCat (dissertations); ClinicalTrials.gov; China Masters' Theses; China Academic Journals; China Doctoral Dissertations; China Proceedings of Conference. We also searched the reference lists of relevant studies and reviews. We included studies that randomised healthy parent-infant dyads (where the infant was under the age of six months) to an infant massage group or a 'no-treatment' control group. Studies had to have used a standardised outcome measure of infant mental or physical development. Mean differences (MD) and standardised mean differences (SMD) and 95% confidence intervals (CIs) are presented. Where appropriate, the results have been combined in a meta-analysis using a random-effects model. We included 34 studies, which includes one that was a follow-up study and 20 that were rated as being at high risk of bias.We conducted 14 meta-analyses assessing physical outcomes post-intervention. Nine meta-analyses showed significant findings favouring the intervention group for weight (MD -965.25 g; 95% CI -1360.52 to -569.98), length (MD -1.30 cm; 95% CI -1.60 to -1.00), head circumference (MD -0.81 cm; 95% CI -1.18 to -0.45), arm circumference (MD -0.47 cm; 95% CI -0.80 to -0.13), leg circumference (MD -0.31 cm; 95% CI -0.49 to -0.13), 24-hour sleep duration (MD -0.91 hr; 95% CI -1.51 to -0.30), time spent crying/fussing (MD -0.36; 95% CI -0.52 to -0.19), deceased levels of blood bilirubin (MD -38.11 mmol/L; 95% CI -50.61 to -25.61), and there were fewer cases of diarrhoea, RR 0.39; 95% CI 0.20 to 0.76). Non-significant results were obtained for cortisol levels, mean increase in duration of night sleep, mean increase in 24-hour sleep and for number of cases of upper respiratory tract disease and anaemia.Sensitivity analyses were conducted for weight, length and head circumference, and only the finding for length remained significant following removal of studies judged to be at high risk of bias. These three outcomes were the only ones that could also be meta-analysed at follow-up; although both weight and head circumference continued to be significant at 6-month follow-up, these findings were obtained from studies conducted in Eastern countries only. No sensitivity analyses were possible.We conducted 18 meta-analyses measuring aspects of mental health and development. A significant effect favouring the intervention group was found for gross motor skills (SMD -0.44; 95% CI -0.70 to -0.18), fine motor skills (SMD -0.61; 95% CI -0.87 to -0.35), personal and social behaviour (SMD -0.90; 95% CI -1.61 to -0.18) and psychomotor development (SMD -0.35; 95% CI -0.54 to -0.15); although the first three findings were obtained from only two studies, one of which was rated as being at high risk of bias, and the finding for psychomotor development was not maintained following following removal of studies judged to be at high risk of bias in a sensitivity analysis. No significant differences were found for a range of aspects of infant temperament, parent-infant interaction and mental development. Only parent-infant interaction could be meta-analysed at follow-up, and the result was again not significant. These findings do not currently support the use of infant massage with low-risk groups of parents and infants. Available evidence is of poor quality, and many studies do not address the biological plausibility of the outcomes being measured, or the mechanisms by which change might be achieved. Future research should focus on the impact of infant massage in higher-risk groups (for example, demographically and socially deprived parent-infant dyads), where there may be more potential for change.

Mammalian sleep

2005-05-01

This review examines the biological background to the development of ideas on rapid eye movement sleep (REM sleep), so-called paradoxical sleep (PS), and its relation to dreaming. Aspects of the phenomenon which are discussed include physiological changes and their anatomical location, the effects of total and selective sleep deprivation in the human and animal, and REM sleep behavior disorder, the latter with its clinical manifestations in the human. Although dreaming also occurs in other sleep phases (non-REM or NREM sleep), in the human, there is a contingent relation between REM sleep and dreaming. Thus, REM is taken as a marker for dreaming and as REM is distributed ubiquitously throughout the mammalian class, it is suggested that other mammals also dream. It is suggested that the overall function of REM sleep/dreaming is more important than the content of the individual dream; its function is to place the dreamer protagonist/observer on the topographical world. This has importance for the developing infant who needs to develop a sense of self and separateness from the world which it requires to navigate and from which it is separated for long periods in sleep. Dreaming may also serve to maintain a sense of ‘I’ness or “self” in the adult, in whom a fragility of this faculty is revealed in neurological disorders.

Coffee, caffeine, and sleep: A systematic review of epidemiological studies and randomized controlled trials.

PubMed

Caffeine is the most widely consumed psychoactive substance in the world. It is readily available in coffee and other foods and beverages, and is used to mitigate sleepiness, enhance performance, and treat apnea in premature infants. This review systematically explores evidence from epidemiological studies and randomized controlled trials as to whether coffee and caffeine have deleterious effects on sleep. Caffeine typically prolonged sleep latency, reduced total sleep time and sleep efficiency, and worsened perceived sleep quality. Slow-wave sleep and electroencephalographic (EEG) slow-wave activity were typically reduced, whereas stage-1, wakefulness, and arousals were increased. Dose- and timing-response relationships were established. The sleep of older adults may be more sensitive to caffeine compared to younger adults. Pronounced individual differences are also present in young people, and genetic studies isolated functional polymorphisms of genes implicated in adenosine neurotransmission and metabolism contributing to individual sensitivity to sleep disruption by caffeine. Most studies were conducted in male adults of Western countries, which limits the generalizability of the findings. Given the importance of good sleep for general health and functioning, longitudinal investigations aimed at establishing possible causal relationships among coffee- and caffeine-induced changes in sleep quality and health development are warranted.

The use of long-term non-invasive ventilation (NIV) to treat sleep and breathing disorders in children has increased substantially in the last decade; however, less data exist about its use in infants. Given that infants have distinct sleep and breathing patterns when compared to older children, the outcomes of infants on long-term NIV may differ as well. The aim of this study is to systematically review the use and outcomes of long-term NIV in infants. Ovid Medline, Ovid Embase, CINAHL (via EbscoHOST), PubMed, and Wiley Cochrane Library were systematically searched from January 1990 to July 2017. Studies on infants using long-term NIV outside of an acute care setting were included. Data were extracted on study design, population characteristics, and NIV outcomes. A total of 327 studies were full-text reviewed, with final inclusion of 60. Studies were distributed across airway (40%), neuromuscular (28%), central nervous system (10%), cardio-respiratory (2%), and multiple (20%) disease categories. Of the 18 airway studies reporting on NIV outcomes, 13 (72%) reported improvements in respiratory parameters. Of the 12 neuromuscular studies exclusively on spinal muscular atrophy type 1 (SMA1), six (50%) reported decreased hospitalizations and nine (75%) reported on mortality outcomes. Risk of bias was moderate to serious, and quality of the evidence was low to very low for all studies. Most studies had an observational design with no control group, limiting the potential for a meta-analysis. The outcomes reported in studies differed by the disease category being studied. Studies on airway conditions showed improvements in respiratory parameters for infants using NIV. Studies on neuromuscular disorder, which were almost exclusively on SMA1, reported decreased hospitalizations and prolonged survival. Overall, it appears that NIV is an effective long-term therapy for infants. However, the high risk of bias and low quality of the available evidence limited strong conclusions.

Towards automated sleep classification in infants using symbolic and subsymbolic approaches.

The paper addresses the problem of automatic sleep classification. A special effort is made to find a method of extracting reasonable descriptions of the individual sleep stages from sample measurements of EGG, EMG, EOG, etc., and from a classification of these measurements provided by an expert. The method should satisfy three requirements: classification accuracy, interpretability of the results, and the ability to select the relevant and discard the irrelevant variables. The solution suggested in this paper consists of a combination of the subsymbolic algorithm LVQ with the symbolic decision tree generator ID3. Results demonstrating the feasibility and utility of our approach are also presented.

Study Objectives: Physiological adaptation to high altitude hypoxia may be impaired in Andeans with significant European ancestry. The respiratory ‘burden’ of sleep may challenge adaptation, leading to relative nocturnal hypoxia. Developmental aspects of sleep-related breathing in high-altitude native children have not previously been reported. We aimed to determine the influence of development on diurnal-nocturnal oxyhemoglobin differences in children living at high altitude. Methods: This was a cross-sectional, observational study. Seventy-five healthy Bolivian children aged 6 mo to 17 y, native to low altitude (500 m), moderate high altitude (2,500 m), and high altitude (3,700 m) were recruited. Daytime resting pulse oximetry was compared to overnight recordings using Masimo radical oximeters. Genetic ancestry was determined from DNA samples. Results: Children had mixed European/Amerindian ancestry, with no significant differences between altitudes. Sixty-two participants had ≥ 5 h of nocturnal, artifact-free data. As predicted, diurnal mean oxyhemoglobin saturation decreased across altitudes (infants and children, both P < 0.001), with lowest diurnal values at high altitude in infants. At high altitude, there was a greater drop in nocturnal mean oxyhemoglobin saturation (infants, P < 0.001; children, P = 0.039) and an increase in variability (all P ≤ 0.001) compared to low altitude. Importantly, diurnal to nocturnal altitude differences diminished (P = 0.036), from infancy to childhood, with no further change during adolescence. Conclusions: Physiological adaptation to high-altitude living in native Andeans is unlikely to compensate for the significant differences we observed between diurnal and nocturnal oxyhemoglobin saturation, most marked in infancy. This vulnerability to sleep-related hypoxia in early childhood has potential lifespan implications. Future studies should characterize the sleep- related respiratory physiology underpinning our observations.

To evaluate whether clinical data support the safety and efficacy of probiotics for the management of infantile colic. Probiotics have been suggested as a potential strategy for infantile colic, and the specific species that have been studied in healthy infants are considered to be safe. A systematic review was conducted to identify randomized controlled trials (RCTs) evaluating the use of probiotic supplementation in infants with colic. RCTs with a primary end point assessing crying or fussing time were selected. A meta-analysis comparing "responders" to "nonresponders" in infants receiving probiotic versus control was conducted. The quality of trials selected was assessed. Five RCTs assessing 2 different strains of the probiotic Lactobacillus reuteri in mostly breastfed infants were identified. Analysis of response rates showed that infants receiving probiotics had a 2.3-fold greater chance of having a 50% or greater decrease in crying/fussing time compared to controls ( P = .01). Probiotic supplementation was not associated with any adverse events. Supplementation with the probiotic L. reuteri in breastfed infants appears to be safe and effective for the management of infantile colic. Further research is needed to determine the role of probiotics in infants who are formula-fed.

Background A chronic or acute insult may affect the regulatory processes that guide motor and behavioral performance, leading to increased intra-individual variability (IIV). Increased variability is often interpreted as an indication of regulatory dysfunction. Iron plays an important role in the regulatory processes of the nervous system and affects motor activity. To our knowledge, no study has examined the long-lasting patterns and IIV of motor activity following iron-deficiency anemia in human infants. Aims This study compared 48-hour motor activity and variability in preschool-aged children with or without iron-deficiency anemia (IDA) in infancy. Methods Motor activity was recorded through actigraphs during two week-days in 47 4-year-old Chilean children (23 former IDA and 24 non-anemic in infancy). All were given oral iron as infants. Sleep-wake states were identified by means of automated software. The frequency of movement units per minute was determined for each waking/sleep state during the individual day and night periods; data were examined in blocks of 15 minutes. Analyses of mean frequency and duration and intra-individual variability were conducted using multivariate mixed models. Results For daytime sleep, former IDA children were more active without a difference in the total duration. They also spent less time awake throughout the individual day period. Motor activity intra-individual variability was higher in former IDA children. Conclusions The findings suggest that IDA in infancy sets the stage for long lasting dysfunction in the neural processes regulating sleep-wake states and spontaneous motor activity patterns.

Technology-supported methods for sleep recording are becoming increasingly affordable. Sleep history feedback may help with fatigue-related decision making - Should I drive? Am I fit for work? This study examines a "sleep tank" model (SleepTank ™ ), which is analogous to the fuel tank in a car, refilled by sleep, and depleted during wake. Required inputs are sleep period time and sleep efficiency (provided by many consumer-grade actigraphs). Outputs include suggested hours remaining to "get sleep" and percentage remaining in tank (Tank%). Initial proof of concept analyses were conducted using data from a laboratory-based simulated nightshift study. Ten, healthy males (18-35y) undertook an 8h baseline sleep opportunity and daytime performance testing (BL), followed by four simulated nightshifts (2000 h-0600 h), with daytime sleep opportunities (1000 h-1600 h), then an 8 h night-time sleep opportunity to return to daytime schedule (RTDS), followed by daytime performance testing. Psychomotor Vigilance Task (PVT) and Karolinska Sleepiness Scale were performed at 1200 h on BL and RTDS, and at 1830 h, 2130 h 0000 h and 0400 h each nightshift. A 40-minute York Driving Simulation was performed at 1730 h, 2030 h and 0300 h on each nightshift. Model outputs were calculated using sleep period timing and sleep efficiency (from polysomnography) for each participant. Tank% was a significant predictor of PVT lapses (p < 0.001), and KSS (p < 0.001), such that every 5% reduction resulted in an increase of two lapses, or one point on the KSS. Tank% was also a significant predictor of %time in the Safe Zone from the driving simulator (p = 0.001), such that every 1% increase in the tank resulted in a 0.75% increase in time spent in the Safe Zone. Initial examination of the correspondence between model predictions and performance and sleepiness measures indicated relatively good predictive value. Results provide tentative evidence that this "sleep tank" model may be an informative tool to aid in individual decision-making based on sleep history. Copyright © 2018 Elsevier Ltd.

2015-01-01

The effects of two food materials, γ-aminobutyric acid (GABA) produced by natural fermentation and Apocynum venetum leaf extract (AVLE), on the improvement of sleep were investigated in humans. The electroencephalogram (EEG) test revealed that oral administration of GABA (100 mg) and AVLE (50 mg) had beneficial effects on sleep. GABA shortened sleep latency by 5.3 min and AVLE increased non-rapid eye movement (REM) sleep time by 7.6%. Simultaneous intake of GABA and AVLE shortened sleep latency by 4.3 min and increased non-REM sleep time by 5.1%. The result of questionnaires showed that GABA and AVLE enabled subjects to realize the effects on sleep. These results mean that GABA can help people to fall asleep quickly, AVLE induces deep sleep, and they function complementarily with simultaneous intake. Since both GABA and AVLE are materials of foods and have been ingested for a long time, they can be regarded as safe and appropriate for daily intake in order to improve the quality of sleep.

The association between placental malaria (PM) and first peripheral parasitaemias in early infancy was assessed in Tori Bossito, a rural area of Benin with a careful attention on transmission factors at an individual level. Statistical analysis was performed on 550 infants followed weekly from birth to 12 months. Malaria transmission was assessed by anopheles human landing catches every 6 weeks in 36 sampling houses and season defined by rainfall. Each child was located by GPS and assigned to the closest anopheles sampling house. Data were analysed by survival Cox models, stratified on the possession of insecticide-treated mosquito nets (ITNs) at enrolment. Among infants sleeping in a house with an ITN, PM was found to be highly associated to first malaria infections, after adjusting on season, number of anopheles, antenatal care (ANC) visits and maternal severe anaemia. Infants born from a malaria infected placenta had a 2.13 fold increased risk to present a first malaria infection than those born from a non infected placenta ([1.24-3.67], p<0.01) when sleeping in a house with an ITN. The risk to present a first malaria infection was increased by 3.2 to 6.5, according to the level of anopheles exposure (moderate or high levels, compared to the absence of anopheles). First malaria infections in early childhood can be attributed simultaneously to both PM and high levels of exposure to infected anopheles. Protective measures as Intermittent Preventive Treatment during pregnancy (IPTp) and ITNs, targeted on both mothers and infants should be reinforced, as well as the research on new drugs and insecticides. In parallel, investigations on placental malaria have to be strengthened to better understand the mechanisms involved, and thus to protect adequately the infants high risk group.

Abnormal respiratory rate (RR) is a key symptom of disease in the newborn. The aim of this study was to establish the reference range for RR during the first 24 hours of life in healthy infants born at term. Infants were included at the hospital postnatal ward when time permitted. During sleep or a defined quiet state, RR was counted at 2, 4, 8, 16, and 24 hours by placing the bell of a stethoscope in front of the nostrils and mouth for 60 seconds. Data on maternal health, pregnancies, and births were obtained from medical records and the Medical Birth Registry of Norway. The study included 953 infants. Median RRs were 46 breaths/minute at 2 hours, thereafter 42 to 44 breaths/minute. The 95th percentile was 65 breaths/minute at 2 hours, thereafter 58 to 60 breaths/minute. The fifth percentile was 30 to 32 breaths/minute. Within these limits, the intraindividual variation was wide. The overall mean RR was 5.2 (95% confidence interval [CI], 4.7 to 5.7, P < .001) breaths/minute higher while awake than during sleep, 3.1 (95% CI, 1.5 to 4.8, P < .001) breaths/minute higher after heavy meconium staining of the amniotic fluid, and 1.6 (95% CI, 0.8 to 2.4, P < .001) breaths/minute higher in boys than girls. RR did not differ for infants born after vaginal versus cesarean deliveries. The RR percentiles established from this study allow for a scientifically based use of RR when assessing newborn infants born at term. Copyright © 2016 by the American Academy of Pediatrics.

Effects of intrauterine growth restriction on sleep and the cardiovascular system: The use of melatonin as a potential therapy?

PubMed

Yiallourou, Stephanie R; Wallace, Euan M; Miller, Suzanne L; Horne, Rosemary S C

2016-04-01

Intrauterine growth restriction (IUGR) complicates 5-10% of pregnancies and is associated with increased risk of preterm birth, mortality and neurodevelopmental delay. The development of sleep and cardiovascular control are closely coupled and IUGR is known to alter this development. In the long-term, IUGR is associated with altered sleep and an increased risk of hypertension in adulthood. Melatonin plays an important role in the sleep-wake cycle. Experimental animal studies have shown that melatonin therapy has neuroprotective and cardioprotective effects in the IUGR fetus. Consequently, clinical trials are currently underway to assess the short and long term effects of antenatal melatonin therapy in IUGR pregnancies. Given melatonin's role in sleep regulation, this hormone could affect the developing infants' sleep-wake cycle and cardiovascular function after birth. In this review, we will 1) examine the role of melatonin as a therapy for IUGR pregnancies and the potential implications on sleep and the cardiovascular system; 2) examine the development of sleep-wake cycle in fetal and neonatal life; 3) discuss the development of cardiovascular control during sleep; 4) discuss the effect of IUGR on sleep and the cardiovascular system and 5) discuss the future implications of melatonin therapy in IUGR pregnancies.

The easy monitoring systems of contact and non-contact living body information for preventing the the Sudden Infant Death Syndrome (SIDS) were proposed as an alternative monitoring system of the infant's vital information. As for the contact monitoring system, respiration sensor, ECG electrodes, thermistor and IC signal processor were integrated into babies' nappy holder. This contact-monitoring unit has RF transmission function and the obtained data are analyzed in real time by PC. In non-contact mortaring system, the infrared thermo camera was used. The surrounding of the infant's mouth and nose is monitored and the respiration rate is obtained by thermal image processing of its temperature change image of expired air. This proposed system of in-sleep infant's vital information monitoring system and unit are very effective as not only infant's condition monitoring but also nursing person's one.

To determine the relationships between maternal depressive symptoms and the use of infant health services, parenting practices, and injury-prevention measures. A prospective, community-based survey of women attending Philadelphia public health centers between February 2000 and November 2001 was conducted. Women were surveyed at 3 time points before and after parturition. Depressive symptoms were determined with the Center for Epidemiologic Studies Depression Scale at each time point. We studied 6 outcomes, clustered into 3 categories: 1) infant health service use (adequate well-child care and ever being hospitalized); 2) parenting practices (breastfeeding for > or =1 month and use of corporal punishment); and 3) injury-prevention measures (having a smoke alarm and using the back sleep position). The sample consisted of 774 largely single (74%), uninsured (63%), African American (65%) women, with a mean age of 24 +/- 6 years and a mean annual income of 8063 dollars. Forty-eight percent of women had depressive symptoms at 1 or 2 time points (ever symptoms) and 12% had depressive symptoms at all points (persistent symptoms). Compared with women who never had depressive symptoms (without symptoms), women with persistent symptoms were nearly 3 times as likely to have their child ever hospitalized (adjusted odds ratio: 2.89; 95% confidence interval: 1.61-5.07) and twice as likely to use corporal punishment (adjusted odds ratio: 1.90; 95% confidence interval: 1.08-3.34). Mothers with persistent depressive symptoms were nearly three-quarters less likely to have smoke alarms in their homes (adjusted odds ratio: 0.28; 95% confidence interval: 0.11-0.70) and one-half as likely to use the back sleep position (adjusted odds ratio: 0.56; 95% confidence interval: 0.35-0.91), compared with women without symptoms. There was no association between maternal depressive symptoms and infant receipt of well-child care or the likelihood of breastfeeding for > or =1 month. Maternal depressive symptoms persisting from the prepartum to postpartum periods were associated with increased risks of infant hospitalization and use of corporal punishment and with lower likelihood of having a smoke alarm and using the back sleep position. Additional efforts are needed to identify and evaluate mothers with depressive symptoms to improve the health and safety of young infants.

Bed-sharing, breastfeeding and maternal moods in Barbados.

PubMed

Galler, Janina R; Harrison, Robert H; Ramsey, Frank

2006-12-01

Bed-sharing among Barbadian mothers and infants was studied in relationship to maternal and infant characteristics. This prospective study followed 226 healthy, well-nourished mother-infant dyads at birth, 7 weeks, 3 months, and 6 months postpartum. At each age, approximately half of the infants shared the same beds as their mothers. Bed-sharing was associated with demographic characteristics, especially fewer home conveniences, and also maternal characteristics, including less information seeking by the mother and younger maternal age at first pregnancy. Bed-sharing was also associated with lower infant birth weights. Maternal moods were significantly correlated with bed-sharing, such that mothers who reported having more despair and anxiety were also more likely to sleep with their infants. Bed-sharing was also significantly associated with increased breastfeeding at all infant ages, but this relationship was no longer significant once the effects of maternal moods were controlled. This study emphasizes the importance of assessing maternal moods in studies evaluating the risk and benefits of bed-sharing.

Background and objective Population-appropriate lung function reference data are essential to accurately identify respiratory disease and measure response to interventions. There are currently no reference data in African infants. The aim was to describe normal lung function in healthy African infants. Methods Lung function was performed on healthy South African infants enrolled in a birth cohort study, the Drakenstein child health study. Infants were excluded if they were born preterm or had a history of neonatal respiratory distress or prior respiratory tract infection. Measurements, made during natural sleep, included the forced oscillation technique, tidal breathing, exhaled nitric oxide and multiple breath washout measures. Results Three hundred sixty-three infants were tested. Acceptable and repeatable measurements were obtained in 356 (98%) and 352 (97%) infants for tidal breathing analysis and exhaled nitric oxide outcomes, 345 (95%) infants for multiple breath washout and 293 of the 333 (88%) infants for the forced oscillation technique. Age, sex and weight-for-age z score were significantly associated with lung function measures. Conclusions This study provides reference data for unsedated infant lung function in African infants and highlights the importance of using population-specific data. PMID:26134556

Because early life growth has long-lasting metabolic and behavioral consequences, intervention during this period of developmental plasticity may alter long-term obesity risk. While modifiable factors during infancy have been identified, until recently, preventive interventions had not been tested. The Intervention Nurses Starting Infants Growing on Healthy Trajectories (INSIGHT). Study is a longitudinal, randomized, controlled trial evaluating a responsive parenting intervention designed for the primary prevention of obesity. This "parenting" intervention is being compared with a home safety control among first-born infants and their parents. INSIGHT's central hypothesis is that responsive parenting and specifically responsive feeding promotes self-regulation and shared parent-child responsibility for feeding, reducing subsequent risk for overeating and overweight. 316 first-time mothers and their full-term newborns were enrolled from one maternity ward. Two weeks following delivery, dyads were randomly assigned to the "parenting" or "safety" groups. Subsequently, research nurses conduct study visits for both groups consisting of home visits at infant age 3-4, 16, 28, and 40 weeks, followed by annual clinic-based visits at 1, 2, and 3 years. Both groups receive intervention components framed around four behavior states: Sleeping, Fussy, Alert and Calm, and Drowsy. The main study outcome is BMI z-score at age 3 years; additional outcomes include those related to patterns of infant weight gain, infant sleep hygiene and duration, maternal responsiveness and soothing strategies for infant/toddler distress and fussiness, maternal feeding style and infant dietary content and physical activity. Maternal outcomes related to weight status, diet, mental health, and parenting sense of competence are being collected. Infant temperament will be explored as a moderator of parenting effects, and blood is collected to obtain genetic predictors of weight status. Finally, second-born siblings of INSIGHT participants will be enrolled in an observation-only study to explore parenting differences between siblings, their effect on weight outcomes, and carryover effects of INSIGHT interventions to subsequent siblings. With increasing evidence suggesting the importance of early life experiences on long-term health trajectories, the INSIGHT trial has the ability to inform future obesity prevention efforts in clinical settings.

The brown tree snake, Boiga irregularis, is abundant on Guam and commonly invades human habitations. Data on emergency room visits on Guam document a high freguency of snakebites on Guam. Over 50% of the emergency room visits for snakebite involved children <4 years old. Records exist of 4 infants, 1, 2, 5, and 10 months old, who displayed significant symptoms after being bitten, while sleeping, by snakes. Two infants developed respiratory problems within a few hours and required medical treatment for asphyxiation. Lethargy, diminished sensory perceptions, drooping eyelids, swelling, discoloration, and bleb formation were variable in occurrence in the patients.

2016-09-01

Tongue-lip adhesion (TLA) is commonly used to relieve obstructive sleep apnea (OSA) in infants with Robin sequence (RS), but few studies have evaluated its efficacy with objective measures. The purpose of this study was to measure TLA outcomes using polysomnography. Our hypothesis was that TLA relieves OSA in most infants. This is a retrospective study of infants with RS who underwent TLA from 2011 to 2014 and had at least a postoperative polysomnogram. Predictor variables included demographic and birth characteristics, surgeon, syndromic diagnosis, GILLS score, preoperative OSA severity, and clinical course. A successful outcome was defined as minimal OSA (apnea-hypopnea index score < 5) on postoperative polysomnogram and no need for additional airway intervention. Descriptive, bivariate, and regression statistics were computed, and statistical significance was set at P < .05. Eighteen subjects who had TLA at a mean age of 28 ± 4.7 days were included. Thirteen (72.2%) had a confirmed or suspected syndrome, and the mean GILLS score was 3 ± 0.3. All parameters trended toward improvement from the preoperative to postoperative polysomnograms, and improvement in OSA severity, oxygen saturation nadir, and arousals per hour was statistically significant (P < .02). This effect was significant across categories of surgeon, syndrome, and GILLS score. Nine subjects (50%) met the criteria for a successful outcome. Bivariate and regression analyses did not demonstrate a significant relationship between success and any predictor variable. TLA improved airway obstruction in all infants with RS but resolved OSA in only nine patients, and success was unpredictable.

Study Objectives: (1) To describe the prevalence of and risk factors for postpartum maternal sleep problems and depressive symptoms simultaneously, (2) identify factors independently associated with either condition, and (3) explore associations between specific postpartum sleep components and depression. Design: Cross-sectional. Setting: Population-based. Participants: All women (n = 4191) who had delivered at Stavanger University Hospital from October 2005 to September 2006 were mailed a questionnaire seven weeks postpartum. The response rate was 68% (n = 2830). Interventions: None. Measurements and results: Sleep was measured using the Pittsburgh Sleep Quality Index (PSQI), and depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS). The prevalence of sleep problems, defined as PSQI > 5, was 57.7%, and the prevalence of depression, defined as EPDS ≥ 10, was 16.5%. The mean self-reported nightly sleep duration was 6.5 hours and sleep efficiency 73%. Depression, previous sleep problems, being primiparous, not exclusively breastfeeding, or having a younger or male infant were factors associated with poor postpartum sleep quality. Poor sleep was also associated with depression when adjusted for other significant risk factors for depression, such as poor partner relationship, previous depression, depression during pregnancy and stressful life events. Sleep disturbances and subjective sleep quality were the aspects of sleep most strongly associated with depression. Conclusions: Poor sleep was associated with depression independently of other risk factors. Poor sleep may increase the risk of depression in some women, but as previously known risk factors were also associated, mothers diagnosed with postpartum depression are not merely reporting symptoms of chronic sleep deprivation.

Dummy/pacifier use is protective for sudden infant death syndrome (SIDS); however, the mechanism/s for this are unknown. As impaired cardiovascular control may be the underlying cause of SIDS, we assessed the effects of dummy/pacifier use on cardiovascular control during sleep within the first 6 months of life. Term infants, divided into dummy/pacifier users and non-dummy/pacifier users, were studied at 2-4 weeks (n = 27), 2-3 months (n = 35) and 5-6 months (n = 31) using daytime polysomnography. Heart rate, blood pressure (BP), heart rate variability (HRV), blood pressure variability (BPV), and baroreflex sensitivity (BRS) were measured in triplicate 1-2-min epochs during quiet and active sleep in the supine and prone positions. Overall, during the non-sucking periods, in the prone position, the BP was higher (10-22 mmHg) in dummy/pacifier users compared to non-users at 2-4 weeks and 5-6 months (p < 0.05 for both). HRV and BRS were higher in dummy/pacifier users compared to non-users at 2-4 weeks (p < 0.05). Active sucking increased HRV and BPV, consistent with increased sympathetic activity in dummy/pacifier users. Higher BP and HRV in dummy/pacifier users indicate increased sympathetic tone, which may serve as a protective mechanism against possible hypotension leading to SIDS; however, these effects were not apparent at 2-3 months, when the risk of SIDS is highest.

Skin-to-skin contact (SSC) promotes physiological stability and interaction between parents and infants. Temporal analyses of predictability in EEG-sleep time series can elucidate functional brain maturation between SSC and non-SSC cohorts at similar post-menstrual ages (PMAs). Sixteen EEG-sleep studies were performed on eight preterm infants who received 8 weeks of SSC, and compared with two non-SSC cohorts at term (N=126) that include a preterm group corrected to term age and a full term group. Two time series measures of predictability were used for comparisons. The SSC premature neonate group had increased complexity when compared to the non-SSC premature neonate group at the same PMA. Discriminant analysis shows that SSC neonates at 40 weeks PMA are closer to the full term neonate non-SSC group than to the premature non-SSC group at the same PMA; suggesting that the KC intervention accelerates neurophysiological maturation of premature neonates. Based on the hypothesis that EEG-derived complexity increases with neurophysiological maturation as supported by previously published research, SSC accelerates brain maturation in healthy preterm infants as quantified by time series measures of predictability when compared to a similar non-SSC group. Times series methods that quantify predictability of EEG sleep in neonates can provide useful information about altered neural development after developmental care interventions such as SSC. Analyses of this type may be helpful in assessing other neuroprotection strategies. Copyright © 2012 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.

Dysphonations in infant cry: A potential marker for health status

NASA Astrophysics Data System (ADS)

Abbs, Katlin J.

Sudden infant death syndrome (SIDS) is defined as an unexplained death in an infant's first year of life. Risk factors for SIDS include maternal smoking, sex, and infant sleep positioning, among others. The current study analyzed dysphonations in the cries of 32 infants 24-66 hours after birth. Dysphonations are acoustic characteristics of cries and include frequency shift (FS), harmonic doubling (HD), biphonation (BP), and noise (N). An interaction effect was found, male infants whose mothers smoked during pregnancy (maternal smoking status) had a significantly lower percent of dysphonations than male infants whose mothers did not smoke during pregnancy (no maternal smoking status). No significant main effects were found for the factors maternal smoking status, sex, infant positioning, or partition. In addition, the types of dysphonations were consistently distributed across groups with noise being the most commonly occurring dysphonation followed by harmonic doubling, frequency shift and then biphonation. It is hypothesized that differences in number and type of dysphonations may either be an effect of differences in infant arousal and/or developmental differences. A lower number of dysphonations seen in male infants with mothers who smoked during pregnancy may suggest a lowered arousal state, which may be associated with the occurrence of SIDS.

The relationship between bedding and face-down death in infancy: mathematical analysis of a respiratory simulation system using an infant mannequin to assess gas diffusibility in bedding.

Rebreathing is a model for the relationship between a prone sleeping position and sudden infant death syndrome. This study used a mechanical simulation model to establish the relationship between types of bedding and rebreathing potential for an infant placed prone (face down) at different postnatal ages. The infant mannequin was connected to a respirator set to deliver physiologically appropriate combinations of tidal volume (V(T)) and respiratory rates (RR) across a range of postnatal ages (0-18 months). Before measurements were made, CO(2) flow was regulated to 5+/-0.1% of end-tidal PCO(2) (EtCO(2)). After the model was placed in a prone position, any increase in the fractional concentration of inspired CO(2) (FiCO(2)) was measured. FiCO(2) increased immediately and rapidly, and reached a maximum value within a few minutes. The maximum FiCO(2) ranged from under 2% to over 10%, depending on the bedding. FiCO(2) was also affected by V(T) and RR. This model is not applicable to actual infants because of the large tissue stores of CO(2) in infants; however, it is useful for evaluation of gas diffusibility of bedding and will simplify the investigation of sleeping environments when a baby is found dead with its face covered by soft bedding. In general, the higher the FiCO(2), the greater the rebreathing potential. Theoretically, considering the paucity of body stores of O(2), changes in FiO(2) would be affected not by changes in FiCO(2), but by CO(2) production and gas movement around the infant's face. The rapid decrease of FiO(2) is approximated at the inverse of the FiCO(2) timecourse, suggesting the significance of not only CO(2) accumulation but also O(2) deprivation in the potential space around the baby's face.

Central nervous system integration of sensorimotor signals in oral and pharyngeal structures: oropharyngeal kinematics response to recurrent laryngeal nerve lesion.

Safe, efficient liquid feeding in infant mammals requires the central coordination of oropharyngeal structures innervated by multiple cranial and spinal nerves. The importance of laryngeal sensation and central sensorimotor integration in this system is poorly understood. Recurrent laryngeal nerve lesion (RLN) results in increased aspiration, though the mechanism for this is unclear. This study aimed to determine the effect of unilateral RLN lesion on the motor coordination of infant liquid feeding. We hypothesized that 1) RLN lesion results in modified swallow kinematics, 2) postlesion oropharyngeal kinematics of unsafe swallows differ from those of safe swallows, and 3) nonswallowing phases of the feeding cycle show changed kinematics postlesion. We implanted radio opaque markers in infant pigs and filmed them pre- and postlesion with high-speed videofluoroscopy. Markers locations were digitized, and swallows were assessed for airway protection. RLN lesion resulted in modified kinematics of the tongue relative to the epiglottis in safe swallows. In lesioned animals, safe swallow kinematics differed from unsafe swallows. Unsafe swallow postlesion kinematics resembled prelesion safe swallows. The movement of the tongue was reduced in oral transport postlesion. Between different regions of the tongue, response to lesion was similar, and relative timing within the tongue was unchanged. RLN lesion has a pervasive effect on infant feeding kinematics, related to the efficiency of airway protection. The timing of tongue and hyolaryngeal kinematics in swallows is a crucial locus for swallow disruption. Laryngeal sensation is essential for the central coordination in feeding of oropharyngeal structures receiving motor inputs from different cranial nerves.

The authors developed a method useful for home measurement of temperature, activity, and sleep rhythms in infants under normal-living conditions during their first 6 mos of life. In addition, parametric and nonparametric tests for assessing circadian system maturation in these infants were compared. Anthropometric parameters plus ankle skin temperature and activity were evaluated in 10 infants by means of two data loggers, Termochron iButton (DS1291H, Maxim Integrated Products, Sunnyvale, CA) for temperature and HOBO Pendant G (Hobo Pendant G Acceleration, UA-004-64, Onset Computer Corporation, Bourne, MA) for motor activity, located in special baby socks specifically designed for the study. Skin temperature and motor activity were recorded over 3 consecutive days at 15 days, 1, 3, and 6 mos of age. Circadian rhythms of skin temperature and motor activity appeared at 3 mos in most babies. Mean skin temperature decreased significantly by 3 mos of life relative to previous measurements (p = .0001), whereas mean activity continued to increase during the first 6 mos. For most of the parameters analyzed, statistically significant changes occurred at 3-6 mos relative to 0.5-1 mo of age. Major differences were found using nonparametric tests. Intradaily variability in motor activity decreased significantly at 6 mos of age relative to previous measurements, and followed a similar trend for temperature; interdaily stability increased significantly at 6 mos of age relative to previous measurements for both variables; relative amplitude increased significantly at 6 mos for temperature and at 3 mos for activity, both with respect to previous measurements. A high degree of correlation was found between chronobiological parametric and nonparametric tests for mean and mesor and also for relative amplitude versus the cosinor-derived amplitude. However, the correlation between parametric and nonparametric equivalent indices (acrophase and midpoint of M5, interdaily stability and Rayleigh test, or intradaily variability and P(1)/P(ultradian)) despite being significant, was lower for both temperature and activity. The circadian function index (CFI index), based on the integrated variable temperature-activity, increased gradually with age and was statistically significant at 6 mos of age. At 6 mos, 90% of the infants' rest period coincided with the standard sleep period of their parents, defined from 23:00 to 07:00 h (dichotomic index I < O; when I < O = 100%, there is a complete coincidence between infant nocturnal rest period and the standard rest period), whereas at 15 days of life the coincidence was only 75%. The combination of thermometry and actimetry using data loggers placed in infants' socks is a reliable method for assessing both variables and also sleep rhythms in infants under ambulatory conditions, with minimal disturbance. Using this methodological approach, circadian rhythms of skin temperature and motor activity appeared by 3 mos in most babies. Nonparametric tests provided more reliable information than cosinor analysis for circadian rhythm assessment in infants.

The hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks. The aim of this study was to assess the effects of hammock positioning on behavioral status, vital signs, and pain in very low birth weight preterm newborns. This is a quasi-experimental/case series study in which premature infants (<1500g) were positioned in supine for one hour in a hammock. The preterm newborns were assessed 10min before, during (2, 20, 40, and 60min), and 10min after hammock positioning with the Brazelton Neonatal Behavioral Assessment Scale, vital signs and pain by the Neonatal Facial Coding System. 28 preterm infants between 28 and 36 weeks of gestational age were evaluated. Regarding the behavioral state, the preterm newborns progressively evolved to light or deep sleep during hammock positioning. There was a statistically significant reduction of the heart and respiratory rate from 2 to 60th minute in a hammock, which was maintained after the positioning. The oxygen saturation remained within normal values. No changes in pain scores were observed. The hammock positioning can be considered a safe method of positioning that can be used to reduce the stress levels in very low birth weight preterm newborns. We did not observe worsening in either pain or vital signs. Copyright © 2018 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia. Publicado por Elsevier Editora Ltda.

Mother-to-child transmission (MTCT) of HIV, has been a major global public health burden. Despite the use of antiretroviral prophylaxis by HIV-positive pregnant women and their infants, safe obstetric practice and safe infant feeding habits in the prevention of MTCT of HIV, the prevalence of HIV among HIV-exposed infants is still high in Cameroon. Our objectives were to determine the prevalence, assess the predictors and determine the effect of combination antiretroviral therapy (cART) on MTCT of HIV at the regional hospital in Bamenda, Cameroon. This was a retrospective study. Secondary data from 877 HIV-exposed infants aged ≤ 72 weeks were extracted from the records between January 2008 and December 2014. The predictors and effect of cART on MTCT of HIV were analysed using a multivariable logistic regression model and risk analysis, respectively. Out of 877 HIV-exposed infants, 62 were positive for HIV, giving a prevalence of 7.1%. Maternal antiretroviral intervention and infant age group were statistically significant predictors of MTCT of HIV. HIV-positive mothers who were on cART were 2.49 times less likely to transmit HIV than those who were not on cART. In order to reduce the prevalence of HIV among HIV-exposed infants, maternal antiretroviral intervention should be targeted and the use of cART by HIV-positive pregnant women should be encouraged.

Is Less Noise, Light and Parental/Caregiver Stress in the Neonatal Intensive Care Unit Better for Neonates?

In utero sensory stimuli and interaction with the environment strongly influence early phases of fetal and infant development. Extremely premature infants are subjected to noxious procedures and routine monitoring, in addition to exposure to excessive light and noise, which disturb the natural sleep cycle and induce stress. Non-invasive ventilation, measures to prevent sepsis, and human milk feeding improve short-term and long-term neurodevelopmental outcomes in premature infants. To preserve brain function, and to improve quality of life and long-term neurodevelopmental outcomes, the focus now is on the neonatal intensive care unit (NICU) environment and its impact on the infant during hospital stay. The objectives of this write-up are to understand the effects of environmental factors, including lighting and noise in the NICU, on sensory development of the infant, the need to decrease parental and caregiver stress, and to review existing literature, local policies and recommendations.

We report the anesthetic management for a radical operation in an infant with cloacal exstrophy. Diagnosis of cloacal exstrophy with meningocele was made at the 26th week of gestation. Cesarian section was performed under general anesthesia in order to keep the infant in a state of apnea to prevent aerophagia, the so-called "sleeping baby", at the 38th week of gestation. As soon as the infant was born, she was intubated orotracheally and a radical operation (abdominal closure, removal of meningocele, and vesico-intestinal-pelvioplasty) was performed. Some complications occurred during the operation including hypotension, oliguria, hypothermia, hypoproteinemia, hyponatremia and hyperpotassemia. The operation time was 10 hours and 30 minutes. Mechanical ventilation was continued for 4 days in the NICU and the infant was discharged 37 days after the operation. Early prenatal diagnosis and simulation of the operation enabled an effective surgical procedure allowing us to minimize these intraoperative complications.

To describe the prevalence of breastfeeding and sleep location practices among US mothers and the factors associated with these behaviors, including advice received regarding these practices. A nationally representative sample of 3218 mothers who spoke English or Spanish were enrolled at a sample of 32 US birth hospitals between January 2011 and March 2014. Exclusive breastfeeding was reported by 30.5% of mothers, while an additional 29.5% reported partial breastfeeding. The majority of mothers, 65.5%, reported usually room sharing without bed sharing, while 20.7% reported bed sharing. Compared to mothers who room shared without bed sharing, mothers who bed shared were more likely to report exclusive breastfeeding (adjusted odds ratio 2.46, 95% confidence interval 1.76, 3.45) or partial breastfeeding (adjusted odds ratio 1.75, 95% confidence interval 1.33, 2.31). The majority of mothers reported usually room sharing without bed sharing regardless of feeding practices, including 58.2% of exclusively breastfeeding mothers and 70.0% of nonbreastfeeding mothers. Receiving advice regarding sleep location or breastfeeding increased adherence to recommendations in a dose response manner (the adjusted odds of room sharing without bed sharing and exclusive breastfeeding increased as the relevant advice score increased); however, receiving advice regarding sleep location did not affect feeding practices. Many mothers have not adopted the recommended infant sleep location or feeding practices. Receiving advice from multiple sources appears to promote adherence in a dose response manner. Many women are able to both breastfeed and room share without bed sharing, and advice to adhere to both of these recommendations did not decrease breastfeeding rates.

Sudden infant death syndrome: a cybernetic etiology.

PubMed

ben-Aaron, M

2003-01-01

The brain's processes, by hypothesis, involve information processing by an extraordinarily complex, highly sophisticated, self-organizing cybernetic system embedded in the central nervous system. This cybernetic system generates itself in successive stages. Breathing is, by default, an autonomous function, but breath control is learned. If there is not a smooth transfer of function at the time when a successor system (one that enables autonomous breathing to be overridden by voluntary control) takes over, breathing may cease, without any overt cause being detectable, even with a thorough postmortem examination. If conditions are such that, at that point, the infant's body lacks the strength to resume breathing again under autonomic control, Sudden Infant Death Syndrome may result. The theory explains why infants are at greater risk if they sleep face down.

Heart Rate Variability Responses of a Preterm Infant to Kangaroo Care

A 35-week old preterm infant's behavior was fussy and restless in the open crib, but he calmed and fell asleep immediately on being placed skin-to-skin on his mother's chest. Heart rate variability (HRV), a noninvasive method to assess the autonomic nervous system's influence on heart rate, was increased with fussy behavior in the open crib and decreased with sleep during kangaroo care (KC). KC produced changes in behavior and HRV that are illustrative of decreasing stress. PMID:16282226

Sleep is an important marker of healthy development and has been associated with emotional, behavioral, and cognitive development. There is limited longitudinal data on children's sleep with only a few reports from low- and middle-income countries (LMICs). We investigate sleep parameters and associated sociodemographic characteristics in a population-based longitudinal study in Pelotas, Brazil. Data from the Pelotas 2004 Birth Cohort were used (N = 3842). Infant sleep was collected through maternal report at 3, 12, 24, and 48 months: sleep duration, bed and wake time, nighttime awakenings, co-sleeping and sleep disturbances (24 and 48 months). Compared to children in high-income countries (HICs), children in Brazil showed a substantial shift in rhythms with later bed and wake times by approximately 2 hours. These remain stable throughout the first 4 years of life. This population also shows high levels of co-sleeping which remain stable throughout (49.0-52.2%). Later bedtime was associated with higher maternal education and family income. Higher rates of co-sleeping were seen in families with lower income and maternal education and for children who were breastfed. All other sleep parameters were broadly similar to data previously reported from HICs. The shift in biological rhythms in this representative community sample of children in Brazil challenges our understanding of optimal sleep routine and recommendations.

Mechanical model testing of rebreathing potential in infant bedding materials

PubMed Central

Carleton, J.; Donoghue, A.; Porter, W.

1998-01-01

Rebreathing of expired air may be a lethal hazard for prone sleeping infants. This paper describes a mechanical model to simulate infant breathing, and examines the effects of bedding on exhaled air retention. Under simulated rebreathing conditions, the model allows the monitoring of raised carbon dioxide (CO2) inside an artificial lung-trachea system. Resulting levels of CO2 (although probably exaggerated in the mechanical model compared with an infant, due to the model's fixed breathing rate and volume) suggest that common bedding materials vary widely in inherent rebreathing potential. In face down tests, maximum airway CO2 ranged from less than 5% on sheets and waterproof mattresses to over 25% on sheepskins, bean bag cushions, and some pillows and comforters. Concentrations of CO2 decreased with increasing head angle of the doll, away from the face down position. Recreations of 29infant death scenes also showed large CO2 increases on some bedding materials, suggesting these infants could have died while rebreathing.

Caldwell, Barbara A; Redeker, Nancy S

2015-01-01

Minority women living in inner city environments may be at more risk for psychological distress. Maternal stress, anxiety, depression, and psychological trauma can influence the preschool child's behavior and may have a negative impact on the preschool child's sleep patterns. The purpose of the study was to: (a) examine objective and subjective preschool children sleep patterns and (b) explore the relationship between objective and subjective sleep patterns in preschool children and maternal psychological status. A cross-sectional observational design was used. Descriptive analyses and correlations were conducted to examine the data. Twenty-one minority women were recruited from the Special Supplemental Nutrition Program for Women, Infants, and Children Program. Preschool children wore wrist actigraphs, and their sleep efficiency, time in bed, and sleep periods were analyzed. Mothers completed measures on depression, anxiety, stress, and psychological trauma. Mothers' self-report of their children's sleep habits indicated at risk scores for sleep problems. Life stress in the mothers was statistically significant and negatively related to preschool child's sleep duration. Mild to severe symptoms of depression and mild anxiety were reported and criteria for Post Traumatic Stress Disorder were found in 12 of the 21 mothers. The results of the study indicate that parent education on sleep and the minority preschool child should be part of community interventions and screening preschool parents for psychological distress should be considered with referrals for support services. © 2014 Wiley Periodicals, Inc.

Objective The aim of this study was to identify socio-demographic and home environmental predictors of shorter sleep in early childhood, and to examine whether effects were mediated by the timing of bedtime or wake time. Methods Participants were from Gemini, a British birth cohort of twins, and included 1702 children; one randomly selected from each twin pair. Parents reported night-time sleep duration at an average age of 15.8 months (range 14–27 months) using a modified version of the Brief Infant Sleep Questionnaire. Multiple logistic regression models were used to identify predictors of shorter sleep for this study. Results Using a cut-off of <11 h a night, shorter sleep was reported in 14.1% of children. Lower maternal education, non-white ethnic background, being male, low birth weight, living in a home with >1 older child and watching >1 h of TV in the evening were independently associated with shorter sleep. Mediation analyses showed that associations between education, ethnicity, evening TV viewing and sleep were driven predominantly by later bedtimes, while sex differences were driven predominantly by earlier wake times in boys. Conclusion In this sample, multiple environmental factors were associated with shorter sleep in young children, with several operating predominantly through later bedtime. An emphasis on the importance of an early and consistent bedtime could help promote healthy sleep and reduce inequalities in child health. PMID:24726571

Home continuous positive airway pressure for cardiopulmonary indications in infants and children.

Al-Iede, Montaha; Kumaran, Radhagini; Waters, Karen

2018-04-30

A number of reports exist regarding the use of continuous positive airway pressure (CPAP) to manage obstructive sleep apnoea (OSA) in children, which we term 'conventional CPAP'. In contrast, there are few reports of home CPAP use for other indications, which we have grouped under the term 'cardiopulmonary'. The aims of this study were to (1) document cardiopulmonary indications for CPAP use in a cohort of infants and children, and (2) evaluate its effectiveness in this group. Hospital records were reviewed for 645 patients who were commenced on long-term CPAP over a 10-year period at a single-tertiary hospital (Children's Hospital at Westmead). This study evaluated the group where the primary indication for CPAP was not OSA ('cardiopulmonary CPAP'). Data evaluated included: demographics, diagnoses, indications for CPAP, hours of use (compliance) and sleep study results at baseline and on CPAP. Of 645 children, 148 (23%) used home CPAP for cardiopulmonary indications; and 130 (87.8%) of these were included. For this group, mean age at CPAP initiation was 18.6 ± 33.6 months (range one week to 16.8 years). Cardiopulmonary indications for CPAP use included: primary airway diseases 65 (50%), chronic lung diseases 33 (25.4%), congenital heart disease (CHD) 20 (15.4%), and both CHD and airway malacia 12 (9.2%). All sleep study variables improved on CPAP relative to the diagnostic sleep study (p < 0.0001), including reduced respiratory rate with CPAP use (p < 0.0001). CPAP was well tolerated (>4 h/night). Interstitial lung diseases and other cardiorespiratory disorders, often of congenital origin, can be effectively treated with home CPAP whether they are associated with OSA or not. Sleep studies demonstrated improved gas exchange, sleep and reduced work of breathing with CPAP use. Copyright © 2018 Elsevier B.V. All rights reserved.

Infants of smoking (S) and substance misusing (SM) mothers have an increased risk of sudden infant death syndrome. The aim of this study was to test the hypothesis that infants of SM or S mothers compared with infants of non-SM, non-smoking mothers (controls) would have a poorer ventilatory response to hypoxia, which was particularly marked in the SM infants. Physiological study. Tertiary perinatal centre. 21 SM; 21 S and 19 control infants. Infants were assessed before maternity/neonatal unit discharge. Maternal and infant urine samples were tested for cotinine, cannabinoids, opiates, amphetamines, methadone, cocaine and benzodiazepines. During quiet sleep, the infants were switched from breathing room air to 15% oxygen and changes in minute volume were assessed. The SM infants had a greater mean increase (p=0.028, p=0.034, respectively) and a greater magnitude of decline (p<0.001, p=0.018, respectively) in minute volume than the S infants and the controls. The rate of decline in minute volume was greater in the SM infants (p=0.008) and the S infants (p=0.011) compared with the controls. Antenatal substance misuse and smoking affect the infant's ventilatory response to a hypoxic challenge. Published by the BMJ Publishing Group Limited.

Disorders of Sleep and Ventilatory Control in Prader-Willi Syndrome

PubMed Central

Gillett, Emily S.; Perez, Iris A.

2016-01-01

Prader-Willi syndrome (PWS) is an imprinted genetic disorder conferred by loss of paternal gene expression from chromosome 15q11.2-q13. Individuals with PWS have impairments in ventilatory control and are predisposed toward sleep disordered breathing due to a combination of characteristic craniofacial features, obesity, hypotonia, and hypothalamic dysfunction. Children with PWS progress from failure to thrive during infancy to hyperphagia and morbid obesity during later childhood and onward. Similarly, the phenotype of sleep disordered breathing in PWS patients also evolves over time from predominantly central sleep apnea in infants to obstructive sleep apnea (OSA) in older children. Behavioral difficulties are common and may make establishing effective therapy with continuous positive airway pressure (CPAP) more challenging when OSA persists after adenotonsillectomy. Excessive daytime sleepiness (EDS) is also common in patients with PWS and may continue after OSA is effectively treated. We describe here the characteristic ventilatory control deficits, sleep disordered breathing, and excessive daytime sleepiness seen in individuals with PWS. We review respiratory issues that may contribute to sudden death events in PWS patients during sleep and wakefulness. We also discuss therapeutic options for treating sleep disordered breathing including adenotonsillectomy, weight loss, and CPAP. Lastly, we discuss the benefits and safety considerations related to growth hormone therapy. PMID:28933403

Cardiometabolic (CM) risk factors are linked to increased morbidity. Disturbed sleep is associated with CM risk factors in late pregnancy, but little is known about sleep in early pregnancy and CM risk factors. Diary and actigraphy-assessed sleep information, as well as CM outcomes (blood pressure (BP) and body mass index (BMI)), were collected thrice from pregnant women (N=161) in early pregnancy: T1 (10-12 weeks), T2 (14-16 weeks) and T3 (18-20 weeks). The sleep variables evaluated included sleep onset latency (SOL), wake after sleep onset (WASO) and total sleep time (TST). Sleep variables were dichotomised using established clinical cut-offs. BMI and BP significantly changed across time. Women with persistent SOL≥20 min had greater BMI than women without persistent SOL≥20 min prior to covariate adjustment at T1 and T2, but at T3 the BMI values converged. Similar results were observed for persistent WASO≥30 min. Persistently long WASO, as measured by actigraphy, was associated with elevated SBP, after controlling for covariates. Consistent with anecdotal evidence, it appears as if a subset of women report substantial difficulty initiating and maintaining sleep during early pregnancy and this may augment the risk of higher BP and BMI. Understanding these relationships is important as CM risk factors are linked to maternal and infant morbidity. Assessing sleep in early pregnancy may bestow time necessary for appropriate intervention. Copyright © 2014 Elsevier B.V. All rights reserved.

2017-07-01

Breast feeding has been suggested as a potential protective factor against childhood snoring and sleep disordered breathing (SDB). SDB can have major health consequences. The objective of this systematic review is to synthesise the available literature concerning any potential association between infant feeding methods and SDB in young children. Five electronic databases were searched. All searches were inclusive until August 5, 2016. Two authors independently reviewed potentially relevant articles for eligibility. Any prospective or retrospective study, case-control study, cohort study, clinical trial, and cross-sectional study that evaluated the association between infant feeding methods and SDB were included. Data on study design, aim of study, sample size, study population, assessment tool, infant feeding methods, and outcome measures were extracted. Nine studies fulfilled the criteria to be finally included in this review, only cohorts and cross-sectional studies were identified. While seven of the selected studies reported a statistically significant association between breast feeding and reduced risk of SDB, the remaining two studies did not report any association. The main methodological limitation was high heterogeneity in the diagnostic criteria and assessment tools to identify SDB and limited data collection on infant feeding methods. The current evidence may point to a protective association, however, as uncertainty is moderate, any suggestion that breast feeding may or may not decrease the risk of SDB is currently unwarranted. More research on the topic is required to resolve some of the contradictions between included studies. © 2017 John Wiley & Sons Ltd.

Sudden unexpected infant deaths (SUID) accounted for 1 in 3 postneonatal deaths in 2010. Sudden infant death syndrome and accidental sleep-related suffocation are among the most frequently reported types of SUID. The causes of these SUID usually are not obvious before a medico-legal investigation and may remain unexplained even after investigation. Lack of consistent investigation practices and an autopsy marker make it difficult to distinguish sudden infant death syndrome from other SUID. Standardized categories might assist in differentiating SUID subtypes and allow for more accurate monitoring of the magnitude of SUID, as well as an enhanced ability to characterize the highest risk groups. To capture information about the extent to which cases are thoroughly investigated and how factors like unsafe sleep may contribute to deaths, CDC created a multistate SUID Case Registry in 2009. As part of the registry, the Centers for Disease Control and Prevention developed a classification system that recognizes the uncertainty about how suffocation or asphyxiation may contribute to death and that accounts for unknown and incomplete information about the death scene and autopsy. This report describes the classification system, including its definitions and decision-making algorithm, and applies the system to 436 US SUID cases that occurred in 2011 and were reported to the registry. These categories, although not replacing official cause-of-death determinations, allow local and state programs to track SUID subtypes, creating a valuable tool to identify gaps in investigation and inform SUID reduction strategies.

Members of the American Academy of Sleep Medicine developed consensus recommendations for the amount of sleep needed to promote optimal health in children and adolescents using a modified RAND Appropriateness Method. After review of 864 published articles, the following sleep durations are recommended: Infants 4 months to 12 months should sleep 12 to 16 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 1 to 2 years of age should sleep 11 to 14 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 3 to 5 years of age should sleep 10 to 13 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 6 to 12 years of age should sleep 9 to 12 hours per 24 hours on a regular basis to promote optimal health. Teenagers 13 to 18 years of age should sleep 8 to 10 hours per 24 hours on a regular basis to promote optimal health. Sleeping the number of recommended hours on a regular basis is associated with better health outcomes including: improved attention, behavior, learning, memory, emotional regulation, quality of life, and mental and physical health. Regularly sleeping fewer than the number of recommended hours is associated with attention, behavior, and learning problems. Insufficient sleep also increases the risk of accidents, injuries, hypertension, obesity, diabetes, and depression. Insufficient sleep in teenagers is associated with increased risk of self-harm, suicidal thoughts, and suicide attempts.

What Is the Effect of Strength Training on Pain and Sleep in Patients With Fibromyalgia?

PubMed

Andrade, Alexandro; Vilarino, Guilherme Torres; Bevilacqua, Guilherme Guimarães

2017-12-01

The study aimed to investigate the effect of an 8-wk structured strength training program on pain and sleep quality in patients with fibromyalgia. Fifty-two patients with fibromyalgia were evaluated; 31 submitted to strength training and 21 comprised the control group. The instruments used were the Fibromyalgia Impact Questionnaire and The Pittsburgh Sleep Quality Index. The questionnaires were applied before the first training session, at 12 sessions, and after 24 sessions. Descriptive statistics (mean, SD, and frequency) and inferential tests were used. After 8 wks of intervention, significant differences were found between groups in subjective quality of sleep (P = 0.03), sleep disturbance (P = 0.02), daytime dysfunction (P = 0.04), and total sleep score (P < 0.01). The correlation analysis using Spearman's test indicated a positive relationship between the variables of pain intensity and sleep quality (P < 0.01); when pain intensity increased in patients with fibromyalgia, sleep quality worsened. Strength training is safe and effective in treating people with fibromyalgia, and a significant decrease in sleep disturbances occurs after 8 wks of intervention.

Measures to identify infancy mental health problems are essential to guide interventions and reduce the risk of developmental psychopathology in early years. We investigated a new service-setting-based measure the Copenhagen Infant Mental Health Screening (CIMHS) within the general child health surveillance by community health nurses (CHN). The study population of 2973 infants was assessed by CIMHS at age 9-10 months. A subsample of 416 children was examined at age 1½ years, using parent interviews including the Child Behavior Checklist (CBCL 1½-5), Check List of Autism and Toddlers (CHAT), Infant-Toddler Symptom Checklist (ITSCL), and the Bayley Scales of Infant and Toddler Development (BSID) and observations of behavior, communication, and interaction. Child mental disorders were diagnosed according to ICD-10 and parent-child relationship disorders according to DC:0-3R. Statistical analyses included logistic regression analyses adjusted and weighted to adjust for sampling and bias. CIMHS problems of sleep, feeding and eating, emotions, attention, communication, and language were associated with an up to fivefold increased risk of child mental disorders across the diagnostic spectrum of ICD-10 diagnoses. Homo-type continuity was seen in problems of sleep and feeding and eating being associated with a threefold increased risk of disorders within the same area, OR 3.0 (95% CI 1.6-5.4) and OR 2.7 (95% CI 1.7-4.2), respectively. The sensitivity at high CIMHS problem scores was 32% and specificity 86%. In summary, CIMHS identify a broad range of infants' mental health problems that are amenable to guide intervention within the general child health surveillance.

Parent-child bed-sharing: The good, the bad, and the burden of evidence.

The practice of parent and child sharing a sleeping surface, or 'bed-sharing', is one of the most controversial topics in parenting research. The lay literature has popularized and polarized this debate, offering on one hand claims of dangers, and on the other, of benefits - both physical and psychological - associated with bed-sharing. To address the scientific evidence behind such claims, we systematically reviewed 659 published papers (peer-reviewed, editorial pieces, and commentaries) on the topic of parent-child bed-sharing. Our review offers a narrative walkthrough of the many subdomains of bed-sharing research, including its many correlates (e.g., socioeconomic and cultural factors) and purported risks or outcomes (e.g., sudden infant death syndrome, sleep problems). We found general design limitations and a lack of convincing evidence in the literature, which preclude making strong generalizations. A heat-map based on 98 eligible studies aids the reader to visualize world-wide prevalence in bed-sharing and highlights the need for further research in societies where bed-sharing is the norm. We urge for multiple subfields - anthropology, psychology/psychiatry, and pediatrics - to come together with the aim of understanding infant sleep and how nightly proximity to the parents influences children's social, emotional, and physical development.

Imaging of the human upper airway is widely used in medicine, in both clinical practice and research. Common imaging modalities include video endoscopy, X-ray CT, and MRI. However, no current modality is both quantitative and safe to use for extended periods of time. Such a capability would be particularly valuable for sleep research, which is inherently reliant on long observation sessions. We have developed an instrument capable of quantitative imaging of the human upper airway, based on endoscopic optical coherence tomography. There are no dose limits for optical techniques, and the minimally invasive imaging probe is safe for use in overnight studies. We report on the design of the instrument and its use in preliminary clinical studies, and we present results from a range of initial experiments. The experiments show that the instrument is capable of imaging during sleep, and that it can record dynamic changes in airway size and shape. This information is useful for research into sleep disorders, and potentially for clinical diagnosis and therapies.

Why REM sleep? Clues beyond the laboratory in a more challenging world.

Horne, Jim

2013-02-01

REM sleep (REM) seems more likely to prepare for ensuing wakefulness rather than provides recovery from prior wakefulness, as happens with 'deeper' nonREM. Many of REM's characteristics are 'wake-like' (unlike nonREM), including several common to feeding. These, with recent findings outside sleep, provide perspectives on REM beyond those from the laboratory. REM can interchange with a wakefulness involving motor output, indicating that REM's atonia is integral to its function. Wakefulness for 'wild' mammals largely comprises exploration; a complex opportunistic behaviour mostly for foraging, involving: curiosity, minimising risks, (emotional) coping, navigation, when (including circadian timing) to investigate new destinations; all linked to 'purposeful, goal directed movement'. REM reflects these adaptive behaviours (including epigenesis), masked in laboratories having constrained, safe, unchanging, unchallenging, featureless, exploration-free environments with ad lib food. Similarly masked may be REM's functions for today's humans living safe, routine lives, with easy food accessibility. In these respects animal and human REM studies are not sufficiently 'ecological'.

The purpose of this paper was to evaluate and compare the questionnaires regarding sleep quality among children aged up to 12 years old, used in the Portuguese language in Brazil. A search at the literature databases of Lilacs, Scielo and Pubmed was performed using keywords "sleep quality" and "children". Selected Articles were analysed for age of the studied population, the number of questions and the issues addressed thereby, who realized the application, the analysis of the results, and content. Out of 9377 titles, 11 studies were included, performing 7 different questionnaires: Questionnaire to measure quality of life among children with enlarged palatine and pharyngeal tonsils (translation of OSD-6) (1); Inventory of Sleep Habits for Preschool Children (2); the Questionnaire on Obstructive Sleep Apnoea-18 (OSA-18) (3), Sleep Questionnaire by Reimão and Lefévre - QRL (4); the Questionnaire on Sleep Behaviour Patterns (5) and the translation of the Sleep Disturbance Scale for Children (6); Brief Infant Sleep Questionnaire - BISQ (7) . Six of the questionnaires have covered the following issues: snoring and daytime sleepiness. A total of 7 protocols were found to be available in Brazil, the most commonly mentioned being OSA-18 and OSD-6. The use of protocols as a guided interview helps to define diagnosis and treatment among the paediatric population, but its large variability makes it difficult to compare a standardised monitoring process.

Immediately after the 1994 Back-to-Sleep campaign, sudden unexpected infant death (SUID) rates decreased dramatically, but they have remained relatively stable (93.4 per 100 000 live births) since 2000. In this study, we examined trends in SUID rates and disparities by race/ethnicity since the Back-to-Sleep campaign. We used 1995-2013 US period-linked birth-infant death data to evaluate SUID rates per 100 000 live births by non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic, American Indian/Alaska Native, and Asian/Pacific Islander racial/ethnic groupings. To examine racial/ethnic disparities, we calculated rate ratios with NHWs as the referent group. Unadjusted linear regression was used to evaluate trends ( P < .05) in rates and rate ratios. The distribution and rates of SUID by demographic and birth characteristics were compared for 1995-1997 and 2011-2013, and χ 2 tests were used to evaluate significance. From 1995 to 2013, SUID rates were consistently highest for American Indian/Alaska Natives, followed by NHBs. The rate for NHBs decreased significantly, whereas the rate for NHWs also declined, but not significantly. As a result, the disparity between NHWs and NHBs narrowed slightly. The SUID rates for Hispanics and Asian/Pacific Islanders were lower than the rates for NHWs and showed a significant decrease, resulting in an increase in their advantage over NHWs. Each racial/ethnic group showed a unique trend in SUID rates since the Back-to-Sleep campaign. When implementing risk-reduction strategies, it is important to consider these trends in targeting populations for prevention and developing culturally appropriate approaches for racial/ethnic communities.

Infants that succumb to Sudden Infant Death Syndrome (SIDS) have been identified with inner ear dysfunction (IED) at birth and on autopsy. We previously investigated whether IED could play a mechanistic role in SIDS. We discovered that animals with IED displayed significant suppression of movement arousal to a hypoxic-hypercarbic gas mixture under light anesthesia. In the current study we investigated the role of each gas in triggering movements and the response to hypercarbia during natural sleep without anesthesia. Seventeen-day-old CD-1 mice received intra-tympanic gentamicin (IT-Gent) injections to precipitate IED. The movement response to hypercarbia, hypoxia and hypoxia-hypercarbia was compared to controls under light anesthesia. Hypercarbia did not stimulate vigorous movements in any animals under either sleep condition. Hypoxia triggered vigorous movements in controls (p<0.05) and a decreased response in IT-Gent animals under light anesthesia. This contrasted with combined hypoxia-hypercarbia, in which IT-Gent animals displaced significantly suppressed movements compared to controls (p<0.05). Our findings portray that a degree of intact inner ear function is necessary for instigating the movement response. Additionally, hypoxia is the trigger for the movement response while carbon dioxide (CO 2 ) suppresses it. The finding that carbon dioxide did not stimulate movement during natural sleep is an important finding. This contrasts with other studies that have identified hypercarbia as an arousal stimulus with EEG. Further studies are warranted to evaluate the precise role of the inner ear in the movement response and potential association with SIDS. The early detection of IED in SIDS predisposed cases could be invaluable. Copyright © 2016 IBRO. Published by Elsevier Ltd. All rights reserved.

Background Mother-to-child transmission (MTCT) of HIV, has been a major global public health burden. Despite the use of antiretroviral prophylaxis by HIV-positive pregnant women and their infants, safe obstetric practice and safe infant feeding habits in the prevention of MTCT of HIV, the prevalence of HIV among HIV-exposed infants is still high in Cameroon. Objective Our objectives were to determine the prevalence, assess the predictors and determine the effect of combination antiretroviral therapy (cART) on MTCT of HIV at the regional hospital in Bamenda, Cameroon. Methods This was a retrospective study. Secondary data from 877 HIV-exposed infants aged ≤ 72 weeks were extracted from the records between January 2008 and December 2014. The predictors and effect of cART on MTCT of HIV were analysed using a multivariable logistic regression model and risk analysis, respectively. Results Out of 877 HIV-exposed infants, 62 were positive for HIV, giving a prevalence of 7.1%. Maternal antiretroviral intervention and infant age group were statistically significant predictors of MTCT of HIV. HIV-positive mothers who were on cART were 2.49 times less likely to transmit HIV than those who were not on cART. Conclusion In order to reduce the prevalence of HIV among HIV-exposed infants, maternal antiretroviral intervention should be targeted and the use of cART by HIV-positive pregnant women should be encouraged.

Congenital cytomegalovirus (cCMV) infection is common among infants born to HIV-infected women. Nelfinavir (NFV), an antiretroviral drug that is safe during pregnancy, inhibits CMV replication in vitro at concentrations that standard doses achieve in plasma. We hypothesized that infants born to women receiving NFV for prevention of mother-to-child transmission of HIV (PMTCT) would have a reduced prevalence of cCMV infection. The prevalence of cCMV infection was compared among HIV-uninfected infants whose HIV-infected mothers either received NFV for >4 weeks during pregnancy (NFV-exposed) or did not receive any NFV in pregnancy (NFV-unexposed). CMV PCR was performed on infant blood samples collected at <3 weeks from birth. Of the 1,255 women included, 314 received NFV for >4 weeks during pregnancy and 941 did not receive any NFV during pregnancy. The overall prevalence of cCMV infection in the infants was 2.2%, which did not differ by maternal NFV use. Maternal CD4 T cell counts were inversely correlated with risk of cCMV infection, independent of the time NFV was initiated during gestation. Infants with cCMV infection were born 0.7 weeks earlier (P = 0.010) and weighed 170 g less (P = 0.009) than uninfected infants. Among HIV-exposed uninfected infants, cCMV infection was associated with adverse perinatal outcomes. NFV use in pregnancy was not associated with protection against cCMV. Safe and effective strategies to prevent cCMV infection are needed. © 2015 Wiley Periodicals, Inc.

Feelings of loneliness are common among young adults, and are hypothesized to impair the quality of sleep. In the present study, we tested associations between loneliness and sleep quality in a nationally representative sample of young adults. Further, based on the hypothesis that sleep problems in lonely individuals are driven by increased vigilance for threat, we tested whether past exposure to violence exacerbated this association. Data were drawn from the Environmental Risk (E-Risk) Longitudinal Twin Study, a birth cohort of 2232 twins born in England and Wales in 1994 and 1995. We measured loneliness using items from the UCLA Loneliness Scale, and sleep quality using the Pittsburgh Sleep Quality Index. We controlled for covariates including social isolation, psychopathology, employment status and being a parent of an infant. We examined twin differences to control for unmeasured genetic and family environment factors. Feelings of loneliness were associated with worse overall sleep quality. Loneliness was associated specifically with subjective sleep quality and daytime dysfunction. These associations were robust to controls for covariates. Among monozygotic twins, within-twin pair differences in loneliness were significantly associated with within-pair differences in sleep quality, indicating an association independent of unmeasured familial influences. The association between loneliness and sleep quality was exacerbated among individuals exposed to violence victimization in adolescence or maltreatment in childhood. Loneliness is robustly associated with poorer sleep quality in young people, underscoring the importance of early interventions to mitigate the long-term outcomes of loneliness. Special care should be directed towards individuals who have experienced victimization.

Apnea of prematurity is a common condition that is usually treated with caffeine, an adenosine receptor blocker that has powerful influences on the central nervous system. However, little is known about the long-term effects of caffeine on sleep in the developing brain. We hypothesized that neonatal caffeine use resulted in long-term abnormalities in sleep architecture and breathing during sleep. A total of 201 ex-preterm children aged 5-12 years who participated as neonates in a double-blind, randomized, controlled clinical trial of caffeine versus placebo underwent actigraphy, polysomnography, and parental sleep questionnaires. Coprimary outcomes were total sleep time on actigraphy and apnea-hypopnea index on polysomnography. There were no significant differences in primary outcomes between the caffeine group and the placebo (adjusted mean difference of -6.7 [95% confidence interval (CI) = -15.3 to 2.0 min]; P = 0.13 for actigraphic total sleep time; and adjusted rate ratio [caffeine/placebo] for apnea-hypopnea index of 0.89 [95% CI = 0.55-1.43]; P = 0.63). Polysomnographic total recording time and total sleep time were longer in the caffeine group, but there was no difference in sleep efficiency between groups. The percentage of children with obstructive sleep apnea (8.2% of caffeine group versus 11.0% of placebo; P = 0.22) or elevated periodic limb movements of sleep (17.5% in caffeine group versus 11% in placebo group) was high, but did not differ significantly between groups. Therapeutic neonatal caffeine administration has no long-term effects on sleep duration or sleep apnea during childhood. Ex-preterm infants, regardless of caffeine status, are at risk for obstructive sleep apnea and periodic limb movements in later childhood.

Although melatonin is increasingly used for sleep disturbances in children with neurodevelopmental disorders, evidence on effective dose and impact on specific types of sleep disturbance is limited. We assessed 45 children (35 males, mean age: 6.3 ± 1.7 years) with neurodevelopmental disorders (n = 29: intellectual disability; n = 9: autism spectrum disorder; n = 7: attention-deficit/hyperactivity disorder) and sleep disturbances, treated with melatonin (mean duration: 326 days) with doses increased according to response. Thirty-eight percent of children responded to low (2.5-3 mg), 31% to medium (5-6 mg) and 9% to high doses (9-10 mg) of melatonin, with a significant increase in total hours of sleep/night, decreased sleep onset delay and decreased number of awakenings/night (all: p = 0.001), as measured with sleep diaries. No serious adverse events were reported. Melatonin is generally effective and safe in children with neurodevelopmental conditions. Increasing above 6 mg/night adds further benefit only in a small percentage of children.

A key circulatory defence against asphyxia in infancy – the heart of the matter!

A resumption of, and escalation in, breathing efforts (hyperpnoea) reflexively accelerates heart rate (HR) and may facilitate cardiac and circulatory recovery from apnoea. We analysed whether this mechanism can produce a sustained rise in HR (tachycardia) when a sleeping infant is confronted by mild, rapidly worsening asphyxia, simulating apnoea. Twenty-seven healthy term-born infants aged 1–8 days rebreathed the expired gas for 90 s during quiet sleep to stimulate breathing and heart rate. To discriminate cardio-excitatory effects of central respiratory drive, lung inflation, hypoxia, hypercapnia and asphyxia, we varied the inspired O2 level and compared temporal changes in response profiles as respiratory sensitivity to hypoxia and asphyxia ‘reset’ after birth. We demonstrate that asphyxia-induced hyperpnoea and tachycardia strengthen dramatically over the first week with different time courses and via separate mechanisms. Cardiac excitation by hypercapnia improves first, followed by a slower improvement in respiratory hypoxic drive. A rise in CO2 consequently elicits stronger, longer lasting tachycardia than moderate increases in respiratory drive or lung expansion. We suggest that without a strong facilitating action of CO2 on the immature heart, respiratory manoeuvres may be unable to reflexively counteract strong vagal bradycardia. This may increase the vulnerability of some infants to apnoea – asphyxia. PMID:23006482

The study aims are to evaluate cerebral background patterns using amplitude-integrated electroencephalography in newborns with critical congenital heart disease, determine if amplitude-integrated electroencephalography is predictive of preoperative brain injury, and assess the incidence of preoperative seizures. We hypothesize that amplitude-integrated electroencephalography will show abnormal background patterns in the early preoperative period in infants with congenital heart disease that have preoperative brain injury on magnetic resonance imaging. Twenty-four newborns with congenital heart disease requiring surgery at younger than 30 days of age were prospectively enrolled within the first 3 days of age at a tertiary care pediatric hospital. Infants had amplitude-integrated electroencephalography for 24 hours beginning close to birth and preoperative brain magnetic resonance imaging. The amplitude-integrated electroencephalographies were read to determine if the background pattern was normal, mildly abnormal, or severely abnormal. The presence of seizures and sleep-wake cycling were noted. The preoperative brain magnetic resonance imaging scans were used for brain injury and brain atrophy assessment. Fifteen of 24 infants had abnormal amplitude-integrated electroencephalography at 0.71 (0-2) (mean [range]) days of age. In five infants, the background pattern was severely abnormal. (burst suppression and/or continuous low voltage). Of the 15 infants with abnormal amplitude-integrated electroencephalography, 9 (60%) had brain injury. One infant with brain injury had a seizure on amplitude-integrated electroencephalography. A severely abnormal background pattern on amplitude-integrated electroencephalography was associated with brain atrophy (P = 0.03) and absent sleep-wake cycling (P = 0.022). Background cerebral activity is abnormal on amplitude-integrated electroencephalography following birth in newborns with congenital heart disease who have findings of brain injury and/or brain atrophy on preoperative brain magnetic resonance imaging.

Background The association between placental malaria (PM) and first peripheral parasitaemias in early infancy was assessed in Tori Bossito, a rural area of Benin with a careful attention on transmission factors at an individual level. Methodology Statistical analysis was performed on 550 infants followed weekly from birth to 12 months. Malaria transmission was assessed by anopheles human landing catches every 6 weeks in 36 sampling houses and season defined by rainfall. Each child was located by GPS and assigned to the closest anopheles sampling house. Data were analysed by survival Cox models, stratified on the possession of insecticide-treated mosquito nets (ITNs) at enrolment. Principal Findings Among infants sleeping in a house with an ITN, PM was found to be highly associated to first malaria infections, after adjusting on season, number of anopheles, antenatal care (ANC) visits and maternal severe anaemia. Infants born from a malaria infected placenta had a 2.13 fold increased risk to present a first malaria infection than those born from a non infected placenta ([1.24–3.67], p<0.01) when sleeping in a house with an ITN. The risk to present a first malaria infection was increased by 3.2 to 6.5, according to the level of anopheles exposure (moderate or high levels, compared to the absence of anopheles). Conclusions First malaria infections in early childhood can be attributed simultaneously to both PM and high levels of exposure to infected anopheles. Protective measures as Intermittent Preventive Treatment during pregnancy (IPTp) and ITNs, targeted on both mothers and infants should be reinforced, as well as the research on new drugs and insecticides. In parallel, investigations on placental malaria have to be strengthened to better understand the mechanisms involved, and thus to protect adequately the infants high risk group. PMID:22096588

Rectal Metyrapone for Treatment of Hypercortisolism in an Infant with McCune-Albright Syndrome

Infantile Cushing syndrome is an infrequent yet potentially fatal manifestation of McCune-Albright syndrome, for which there are few safe treatments available. Ketoconazole is limited by potential hepatotoxicity in this population. Metyrapone may be an effective treatment, but it may not be tolerated when given orally. An infant with McCune-Albright syndrome presented with severe Cushing syndrome. Oral metyrapone resulted in feeding refusal, and ketoconazole caused an increase in liver enzymes; however, she was successfully treated with metyrapone given rectally. The patient avoided a feeding tube, and her serum cortisol concentration was lowered to a safe level. Metyrapone given per rectum may be a safe and effective alternative to oral metyrapone in treating young children with Cushing syndrome. PMID:28638307
