RESUMO
OBJECTIVE: To describe the presence of obstructive sleep apnea syndrome (OSAS) in children with craniofacial anomalies (CFA), associate biodemographic characteristics and polygraph variables, and analyze the therapeutic management decided after the sleep study and the evaluation by a multidisciplinary team. PATIENTS AND METHOD: Retrospective study. Polygraphs were performed on patients aged between 1 month and 19 years with CFA. An initial and projected management was established categorized into ventilatory support, tracheostomy, surgery, dental, and medical treatment. Descrip tive and inferential statistics were performed, evaluating the association between demographic and polygraph variables and therapeutic management. RESULTS: 34 patients were included with a median age of 4.0 years (IQR 0.9 - 6.5). Diagnosis was 41.2% cleft lip and palate, 35.3% craniosynostosis, and 23.5% micrognathia. Polygraphs were altered in 70.6% of the cases; of these, 26.5% were diagnosed as mild, 5.9% moderate, and 38.2% severe OSAS. There was an association between minimum satu ration and diagnosis of OSAS (p = 0.0036), and in the presence of OSAS with the initial management applied (p=0.0013). There was no significant relationship between the different types of CFA with the initial therapeutic management (p = 0.6565). Initial and projected managements, respectively: Venti latory support (11.8% and 2.9%), tracheostomy (11.8% and 0%), surgery (35.2% and 26.5%), dental (20.6% and 53%), and medical treatment (20.6% and 17.6 %). CONCLUSIONS: 70% of the patients with CFA presented OSAS. The greatest severity was found in Cleft Lip and Palatine and Craniosynostosis. Therapeutic management was mainly oriented towards initial surgical and planned dental treatments based on the diagnosis of OSAS and not on the type of CFA.

INTRODUCTION: In critically ill patients, sleep and circadian rhythms are greatly altered. These disturbances have been associated with adverse consequences, including increased mortality. Factors associated with the ICU environment, such as exposure to inadequate light and noise levels during the day and night or inflexible schedules of daily care activities, have been described as playing an essential role in sleep disturbances. The main objective of this study is to evaluate the impact of the use of a multifaceted environmental control intervention in the ICU on the quantity and quality of sleep, delirium, and post-intensive care neuropsychological impairment in critically ill patients. METHODS: This is a prospective, parallel-group, randomized trial in 56 critically ill patients once they are starting to recover from their acute illness. Patients will be randomized to receive a multifaceted intervention of environmental control in the ICU (dynamic light therapy, auditory masking, and rationalization of ICU nocturnal patient care activities) or standard care. The protocol will be applied from enrollment until ICU discharge. Baseline parameters, light and noise levels, polysomnography and actigraphy, daily oscillation of plasma concentrations of Melatonin and Cortisol, and questionnaires for the qualitative evaluation of sleep, will be assessed during the study. In addition, all patients will undergo standardized follow-up before hospital discharge and at 6 months to evaluate neuropsychological impairment. DISCUSSION: This study is the first randomized clinical trial in critically ill patients to evaluate the effect of a multicomponent, non-pharmacological environmental control intervention on sleep improvement in ICU patients. The results will provide data about the potential synergistic effects of a combined multi-component environmental intervention in ICU on outcomes in the ICU and long term, and the mechanism of action.

Sleep-disordered breathing (SDB) is a prevalent disease in children characterized by snoring and narrowing of the upper airway leading to gas exchange abnormalities during sleep as well as sleep fragmentation. SDB has been consistently associated with problematic behaviors and adverse neurocognitive consequences in children but causality and determinants of susceptibility remain incompletely defined. Since the 1990s several studies have enlightened these associations and consistently reported poorer academic performance, lower scores on neurocognitive tests, and behavioral abnormalities in children suffering from SDB. However, not all children with SDB develop such consequences, and severity of SDB based on standard diagnostic indices has often failed to discriminate among those children with or without neurocognitive risk. Accordingly, a search for discovery of markers and clinically useful tools that can detect those children at risk for developing cognitive and behavioral deficits has been ongoing. Here, we review the advances in this field and the search for possible detection approaches and unique phenotypes of children with SDB who are at greater risk of developing neurocognitive consequences.
RESUMO
Precision medicine requires coordinated and integrated evidence-based combinatorial approaches so that diagnosis and treatment can be tailored to the individual patient. In this context, the treatment approach to mild obstructive sleep apnea (OSA) is fraught with substantial debate as to what is mild OSA, and as to what constitutes appropriate treatment. As such, it is necessary to first establish a proposed consensus of what criteria need to be employed to reach the diagnosis of mild OSA, and then examine the circumstances under which treatment is indicated, and if so, whether and when anti-inflammatory therapy (AIT), rapid maxillary expansion (RME), and/or myofunctional therapy (MFT) may be indicated.
RESUMO
OBJECTIVE: To analyze and identify differences in sleep spindles in children with restless sleep disorder (RSD), restless legs syndrome (RLS) and normal controls. METHODS: PSG (polysomnography) from children with RSD, RLS and normal controls were analyzed. Sleep spindle activity was detected on one frontal and one central electrode, for each epoch of N2 and N3 sleep. Sleep spindle density, duration and intensity (density × duration) were then obtained and used for analysis. RESULTS: Thirty-eight children with RSD, twenty-three children with RLS and twenty-nine controls were included. The duration of frontal spindles in sleep stage N2 was longer in children with RSD than in controls. Frontal spindle density and intensity tended to be increased in RSD children. No significant differences were found for central spindles. CONCLUSION: Children with RSD had longer frontal spindles. This finding may contribute to explain the occurrence of excessive movement activity during sleep and the presence of daytime symptoms. SIGNIFICANCE: Recent research has demonstrated that children with RSD have increased NREM instability and sympathetic activation during sleep. Analyzing sleep spindles in children with RSD in comparison with children with RLS and controls adds to our understanding of the pathophysiology or RSD and its effects on daytime impairment.

NONE: Sleep medicine is a relatively young field with exponential growth in development and research in the last decades. Parallel to the advances in the United States, Latin America also had its beginnings in sleep medicine housed in neuroscience laboratories. Since the very first Latin American meeting in 1985, and the first sleep society in 1993, sleep research has undergone significant development in subsequent years. From contributions in animal research that allowed understanding of the activity of the brain during sleep to the studies that improved our knowledge of sleep disorders in humans, Latin America has become a scientific hub for expansion of sleep research. In this article, we present a historical account of the development of sleep medicine in Latin America, the current state of education and the achievements in research throughout history, and the latest advances in the trending areas of sleep science and medicine. These findings were presented during World Sleep Society meeting in Vancouver in 2019 and complement the work on sleep societies and training published by Vizcarra-Escobar et al in their article "Sleep societies and sleep training programs in Latin America" (J Clin Sleep Med. 2020;16(6):983-988).

BACKGROUND: Little is known on sleep quality of children with atopic dermtitis (AD) during flares and how treatment impacts their sleep. The purpose of this study is to evaluate variations in sleep quality of children with AD during flares and its response to intensified treatment. MATERIAL AND METHODS: Prospective case-crossover study in 10 children with moderate-severe AD. At baseline, AD severity was assessed using SCORAD and patients were prescribed intensified AD therapy. All subjects were monitored by actigraphy during 14 days and returned for SCORAD assessment. RESULTS: Subjects' age was 5.6 ± 5.3 years; 50% were female. Sleep duration was decreased in all subjects and awakenings were increased in 90%. Parental perception of sleep significantly differed from actigraphy results: parents estimated less sleep duration and less awakenings. Nocturnal sleep efficiency at baseline was reduced in 50%. After intensified treatment, median SCORAD decreased from 58.5 to 31.3 (p=0.005), with significant improvement in sleep loss and pruritus visual analogue scales. Despite improvement of SCORAD and parental perception of sleep loss and pruritus, objective sleep duration and efficiency measured by actigraphy did not vary significantly after intensified treatment. Change in SCORAD, sleep loss and pruritus scales did not correlate significantly with change in sleep duration, efficiency or other actigraphic sleep quality measurements. CONCLUSIONS: Children with moderate-severe AD have sleep quality abnormalities, with decreased sleep duration, low sleep efficiency and increased awakenings. Improvement in AD severity upon intensified AD treatment was associated with improved parental perception of sleep loss, but not of objective sleep quality assessed by actigraphy.
RESUMO
El diagnóstico de apneas en lactantes menores de tres meses constituye un gran desafío y es un área en pleno desarrollo. Es por esto, que diferentes especialistas en sueño, pertenecientes a dos Sociedades Científicas de Chile: la Comisión de Sueño, de la Sociedad Chilena de Neumología Pediátrica (SOCHINEP) y el Grupo de Trabajo Trastornos del Sueño en Pediatría de la Sociedad de Psiquiatría y Neurología de la Infancia y Adolescencia (SOPNIA), se han puesto de acuerdo en proponer un consenso básico sobre los parámetros de sueño y del manejo de las apneas en los menores de 3 meses de vida. El objetivo, es que podamos contribuir al manejo de estos pacientes, con un lenguaje y manejo similar, y valores de referencia apropiados para ese grupo etario, respaldado con las últimas investigaciones al respecto.
Sleep apnea diagnosis in infants younger than 3 months has been a major challenge for modern medicine. Using current literature, experts from the Chilean Society of Pediatric Pulmonology Sleep Commission, and the Chilean Society of Psychiatry and Neurology for Children and Adolescents, have produced a national state-of-the-art consensus. The main goal of this statement is to unify our language in this matter, based on the latest evidence.

INTRODUCCIÓN: La Academia Americana de Pediatría recomienda que los lactantes menores de un año duerman en posición supina para prevenir el síndrome de muerte súbita en lactantes (SMSL). OBJETIVO: Describir la posición en que duermen un grupo de lactantes y factores de riesgo asociados al SMSL. SUJETOS Y MÉTODO: Estudio piloto, prospectivo concurrente, de lactantes < 45 días de vida en control sano en Centro Médico San Joaquín UC Christus. Criterios de exclusión: prematurez (edad gestacional < 37 semanas) y patología de base (respiratorias, metabólicas, cardiológicas). Se aplicó encuesta al cuidador principal respecto a datos demográficos y hábitos de sueño, basada en encuesta BISQ (Brief Screening Questionnaire for Infant Sleep Problems) validada en español, dado la inexistencia de instru mentos para < 3 meses. RESULTADOS: Se obtuvo muestra de 100 lactantes de edad 16,78 ± 12,88 días de vida, siendo 57% mujeres. La madre fue el principal informante (84%). El 79% de los lactantes dor mían en decúbito supino, 19% lo hacía de lado y 2% en prono. El 66% dormía en cuna en habitación de los padres, 31% en la cama de los padres. El 74% se quedaban dormidos durante la alimentación. El 28% de los lactantes estaban expuestos a tabaquismo pasivo. El 91% cuidadores estaba informa do sobre la posición segura de sueño, siendo el principal informante el pediatra (54%). CONCLUSIONES: En esta muestra se encontró alto porcentaje de lactantes < 45 días que duermen en posición no segura, siendo frecuente el colecho. Es importante implementar campañas locales de prevención del SMSL que refuercen el hábito de dormir seguro.
INTRODUCTION: The American Academy of Pediatrics recommends, through the implementation of the "Back to Sleep (BTS)" campaign, the supine sleeping position for infant sleeping since it prevents to prevent Sudden Infant Death Syndrome (SIDS). OBJECTIVE: To describe the sleeping position of a group of infants and the risk factors associated with sudden infant death syndrome (SIDS). SUBJECTS AND METHOD: Prospective pilot study, including infants < 45 days of life in well-child care visits at a medical center. Exclusion criteria: Preterm-born infant (gestational age < 37 weeks) and/or comorbidities (pulmonary, metabolic, cardiologic). A brief parental questionnaire was conducted regarding general demographic data and sleep habits. The questioner was based on the BISQ - Spanish version, due to the lack of validated instruments for infants < 3-month-old. RESULTS: We included a sample of 100 infants between 16.78 ± 12.88 days old (57% girls). Mothers were the main information source (84%). 79% of the infants slept in supine position, 19% slept on their sides, and 2% in prone position. Regarding the place where the infants slept, 66% did in their crib in the parents' room and 31% slept in parents' bed. 74% of infants fell asleep while being fed. 28% of infants were exposed to passive smoking at home. 91% of parents were informed about safe sleep positions, reporting that pediatricians were the main source of information (54%). CONCLUSION: We found a high percentage of infants < 45 days of life who slept in an unsafe position, and frequently co-sleep with their parents. Thus, it is important to implement local SIDS prevention campaigns to reinforce safe infant sleep.

STUDY OBJECTIVES: The association of snoring and sleep-disordered breathing (SDB) with daytime sleepiness is well documented; however, the exact mechanisms, and especially the role of sleep microstructure that may account for this association remain incompletely understood. In a cohort of children with SDB, we aimed to compare sleep spindle activity between children with daytime sleepiness versus those without daytime sleepiness. METHODS: Children with SDB who reported daytime sleepiness were recruited and compared with age- and sex-matched SDB controls. Polysomnographic recordings were analyzed evaluating sleep spindle activity. A statistical comparison was carried out in both groups to assess the association between sleepiness and sleep spindle activity. RESULTS: Thirty-three children with SDB (mean age: 7.5 ± 1.7 years) were included, 10 with and 23 without daytime sleepiness. Spindle activity was lower in children with daytime sleepiness compared with those without; in stage N2, median (interquartile range) sleep spindle indexes were 77.5 (37.3) and 116.9 (71.2) (P = .015), respectively. CONCLUSIONS: Spindles were significantly reduced in children with SDB and daytime sleepiness. The exact mechanisms of this association remain unknown and future research is needed in order to establish the exact role of sleep spindle activity on daytime symptoms in children with SDB.

STUDY OBJECTIVES: Prematurity has been associated with an increased risk for sleep apnea. However, sleep disturbances in children born preterm have not been extensively investigated. Considering that determinants of sleep may originate early in life, the potential impact of prematurity on sleep disturbances later in life could be important. To establish the role of prematurity on sleep disturbances in a cohort of schoolchildren that were born preterm and compare them with healthy controls. METHODS: A cohort of 147 schoolchildren, 45 born at term (≥37 weeks) and 102 very preterm (<32 weeks), was recruited and evaluated at school age (5-9 years). The Pediatric Sleep Questionnaire (PSQ) and the Sleep Disturbance Scale for Children (SDSC) were used to assess sleep disturbances in different domains. RESULTS: PSQ score was significantly higher in former preterm children (0.26 ± 0.18 vs. 0.18 ± 0.14 in controls; p = 0.004), and SDSC total score was also significantly different among groups (21.7 ± 11.6 vs. 14.1 ± 12.6; p < 0.001). Regression models showed significant mean differences in PSQ score, total SDSC score, and two SDSC subscale scores (i.e. sleep-wake transition disorders, sleep-breathing disorders, and sleep hyperhidrosis) even after adjustment for confounders. Maternal age and type of delivery were not significantly associated with total PSQ scores. CONCLUSIONS: Sleep disturbances may originate early in life since children born preterm exhibit an increased risk for developing long-term sleep problems. These findings may have important implications for management of preterm children and for implementation of early interventions focused on optimizing sleep habits.

Objective: Sleep-disordered breathing (SDB) is highly prevalent in school children with poorly-controlled asthma. However, this association has not been assessed in preschoolers with recurrent wheeze, nor in those at risk for asthma. We hypothesized that preschoolers with asthma risk (positive asthma predictive index [API]) have a higher prevalence of SDB and higher inflammatory biomarkers (blood-hsCRP and urinary-LTE4) levels than those with negative API.Method: Children 2 to 5 years of age with recurrent wheezing were classified as positive or negative API. SDB was determined by the pediatric sleep questionnaire (PSQ) and its subscale (PSQSub6). Demographic characteristics, spirometry, blood hsCRP and urinary LTE4 were assessed.Results: We enrolled 101 preschoolers: 70 completed all measurements, 55.4% were males, mean age 4.07 ± 0.87 years, 45% overweight or obese, 70% had positive API, 87.5% had rhinitis. The prevalence of SDB measured by PSQ was 40.8% and by PSQSub6 was 29.6%. However, the proportion of SDB was similar between positive and negative API groups. The hsCRP (mean ± SD) was higher in the positive than in negative API (3.58 ± 0.58 and 1.32 ± 0.36 mg/L, p = 0.69, respectively); moreover, no differences in urinary LTE4 were found between groups. No correlation of PSQ (+) or PSQSub6 (+) with hsCRP and uLTE4 was found. However, preschoolers with positive API had significantly more post-bronchodilator percentage change in FEF25-75 than negative API (24.14 ± 28.1 vs. 4.13 ± 21.8, respectively, p = 0.01).Conclusions: In preschoolers with recurrent wheezing, we should be investigating for the coexistence of SDB, using early screening methods for detecting those conditions.

BACKGROUND: Habitually snoring children are at risk of manifesting disease-related problems even if their sleep studies are overall within normal limits. STUDY OBJECTIVES: To compare sleep spindle activity in children with primary snoring and healthy controls. METHODS: Sleep spindle activity including analysis of fast and slow spindles (ie, >13 Hz and <13 Hz, respectively) was evaluated in polysomnographic (PSG) recordings of 20 randomly selected children with primary snoring (PS; normal PSG recordings except for objective presence of snoring; 12 boys, mean age 6.5 ± 2.1 years), and 20 age- and gender-matched PSG-confirmed non-snoring controls. RESULTS: PS children showed significantly lower spindle indices in all non-rapid eye movement (NREM) sleep stages (p < 0.05). In contrast, fast spindles were found in 40% (n = 8) children with PS and in 25% (n = 5) controls. Sleep spindle activity was particularly higher in NREM sleep stage 2 in controls compared PS (76% versus 43% of all marked sleep spindles events in NREM sleep stage 2, p < 0.001). CONCLUSIONS: Children with PS exhibit significantly reduced spindle activity when compared to matched controls. Reduced sleep spindle activity may be an indicator of sleep disruption and, therefore, could be involved in the development of disease-related consequences in snoring children.

El Síndrome de piernas inquietas (SPI) o Enfermedad de WillisEkbom, es una condición neurológica que afecta al 2-4% de los niños en edad escolar. Etiológicamente se ha relacionado al metabolismo del hierro y a factores genéticos entre otros. En niños aun es una patología poco diagnosticada. Trabajo observacional descriptivo, en el cual se realiza caracterización clínica, según criterios internacionales, en 14 pacientes menores de 18 años, 9 varones. Edad promedio 8 años. Sintomatología inicial variada, desde resistencia a ir a la cama, hasta dibujar sus molestias. En 10 se comprobó déficit de hierro. En 11 pacientes se realizó un polisomnograma, 10 de ellos con un índice elevado de movimientos periódicos de extremidades. El uso de pregabalina y aporte de hierro fue el tratamiento más utilizado. Dos pacientes tenían padres diagnosticados con SPI.
Abstract. The Restless Legs Syndrome (RLS) or Willis-Ekbom Disease is a neurological condition that affects 2-4% of school-age children. Its etiology has been related to the metabolism of iron and genetic factors among others. In children it is still a frequently undiagnosed disorder. This is a descriptive observational report, in which clinical characterization is carried out according to international criteria in 14 patients under 18 years old, 9 boys. Average age is 8 years old. The initial symptomatology was varied, from resistance to comply with bedtime, to drawing their discomfort. In 9, iron deficiency was found. A polysomnogram was performed in 11 patients, 10 of which had a high periodic limb movements index. The use of pregabalin and supplementary iron were the most used treatments. Two patients had parents diagnosed with RLS.

BACKGROUND AND OBJECTIVE: Similar to other respiratory diseases, sleep disordered breathing (SDB) may be exacerbated by air contaminants. Air pollution may have an impact on incidence and severity of SDB in children. The aims of this study were to examine potential associations between the exposure to different air pollutants and SDB symptoms in children. METHODS: In this cross-sectional study, parents from first grade children of elementary schools throughout Chile were included. Data about clinical and family-related SDB risk factors, and the pediatric sleep questionnaire (PSQ) were obtained. Air pollution and meteorological data were obtained from the Chilean online air quality database. RESULTS: A total of 564 children (44.9% males) aged (median) 6 years (5-9 year) were included. Prevalence of SDB based on PSQ was 17.7%. When examining air pollutants and conditions, only higher humidity (ß = 0.005, 95%CI 0.001-0.009, P = 0.011) was significantly associated with higher PSQ scores after adjusting for demographic and household variables. Higher ozone (O3 ) levels (OR = 1.693, 95%CI 1.409-2.035, P < 0.001), higher humidity (OR = 1.161, 95%CI 1.041-2.035, P = 0.008) and higher dioxide sulfur (SO2 ) levels (OR = 1.16, 95%CI 1.07-1.94, P < 0.001]) were associated with increased odds of wheezing-related sleep disturbances after adjusting for confounders. Lower temperature was a significant predictor of snoring at least >3 nights/week, following adjustment (OR = 0.865, 95%CI 0.751-0.997, P < 0.05). CONCLUSION: Sleep respiratory symptoms (wheezing and snoring) are significantly associated with air pollutants such as O3 and SO2 . In addition, meteorological conditions such as humidity and low temperatures may be also associated with SDB-related symptoms.

Resumen: Objetivos: Describir la prevalencia de trastornos respiratorios del sueño (TRS) en escolares chilenos y estudiar factores de riesgo asociados. Pacientes y Método: Estudio transversal y descriptivo. Se enviaron cuestionarios a los padres de niños de 1° año básico de colegios de la Región Metropolitana (Santiago), Región del Biobío (Concepción, Chillán, Yumbel) y Región de Magallanes (Porvenir y Puerto Natales). Se consignaron datos antropométricos, desempeño escolar, características del hogar, contaminantes intradomiciliarios, antecedentes médicos y síntomas actuales de asma, rinitis alérgica y dermatitis atópica. Se determinó estado nutricional según zIMC. Se aplicó un cuestionario de sue ño pediátrico validado en español (pediatric sleep questionnaire, PSQ). Resultados: 564 encuestas fueron analizadas, la edad mediana fue 6 años (rango 5 a 9), 44,9% sexo masculino. La prevalencia de TRS fue 17,7% (n = 100): 6% en Vitacura (Metropolitana), 28,7% en Chillán (Biobío) y 36,4% en Puerto Natales (Magallanes) (p = 0,001). El grupo con TRS tuvo mayor proporción de hombres (54,5 vs 42,8%, p = 0,033), menor rendimiento académico (promedio general 6,36 ± 0,48 vs 6,56 ± 0,34, p = 0,001), menor educación superior materna (44,4 vs 69,9%, p = 0,001) y mayor exposición a contaminantes intradomiciliarios que aquellos sin TRS. Posterior al análisis multivariado se mantu vieron como predictor de TRS el haber presentado síntomas de rinitis en últimos 12 meses (OR 4,79; IC 95% 2,20-10,43) y el nivel educacional básico o medio de la madre (OR 3,51; IC 95% 1,53-8,02). Conclusiones: Los escolares chilenos presentan una alta prevalencia de TRS, con diferencias demo gráficas. Se asoció a factores de riesgo social, a factores más específicos de daño pulmonar y a peor cantidad y calidad del sueño.
Abstract: Objectives: To describe the prevalence of sleep-disordered breathing (SDB) in Chilean schoolchil dren and study associated risk factors. Patients and Method: We carried out a transversal and des criptive study. Questionnaires were sent to the parents of children attending first year of elementary school in the Metropolitan Region (Santiago), the Biobío Region (Concepción, Chillán, Yumbel) and the Magallanes Region (Porvenir and Puerto Natales). Anthropometric data, school performan ce, household characteristics, indoor pollutants, medical history, and current symptoms of asthma, allergic rhinitis, and atopic dermatitis were recorded. The nutritional status was determined accor ding to z-BMI. A pediatric sleep questionnaire validated in Spanish (PSQ) was applied. Results: 564 questionnaires were analyzed, the median age was six years (range 5 to 9), 44.9% male. The SDB prevalence was 17.7% (n = 100): 6% in Vitacura (Metropolitan Region), 28.7% in Chillán (Biobío Region), and 36.4% in Puerto Natales (Magallanes Region) (p = 0.001). The group with SDB had a higher proportion of men (54.5 vs 42.8%, p = 0.033), lower academic performance (overall grade point average 6.36 ± 0.48 vs 6.56 ± 0.34, p = 0.001), lower maternal higher education (44.4% vs 69.9%, p = 0.001), and higher exposure to indoor pollutants than those without SDB. After the multivariate analysis, symptoms of rhinitis in the last 12 months (OR 4.79, 95% CI 2.20-10.43) and lower maternal educational level (OR 3.51; 95% CI 1.53-8.02) remained as predictors of SDB. Con clusions: Chilean schoolchildren have a high prevalence of SDB with demographic differences. It was associated with social risk factors, more specific factors of lung damage, and worse sleep quality and quantity.

Resumen. El Insomnio infantil definido como la dificultad mantenida, a pesar de la oportunidad y en función etaria, para iniciar o mantener el sueño o su calidad que provoca alteraciones funcionales en el niño y/o familia. Puede repercutir significativamente en la conducta, aprendizaje y metabolismo del niño y en su familia afectando su calidad de vida. La actigrafía nos permite a través de un dispositivo identificar periodos de vigilia y sueño. El objetivo de este trabajo es caracterizar a través de la actigrafía el patrón sueño-vigilia y evaluar la exposición a luz azul en niños menores de 2 años que consultan por insomnio. Se realizó un estudio observacional, descriptivo, transversal de lactantes derivados por insomnio al Centro de Sueño de Red de Salud UC Christus, durante: Marzo 2017-2018, con actigrafía. Fueron 20 actigrafías de 7 días. Edades entre 5 y 22 meses con diagnóstico de insomnio que no respondió al manejo inicial. 8 hombres, 12 mujeres. Horarios promedios: Acostarse: 20:31 hrs. Levantarse: 7:43 hrs. Horarios variables para acostarse: 15/20. 10/20 siestas después de las 16 hrs. Todos presentaron tiempo total de sueño disminuido, con aumentos del tiempo despierto una vez iniciado el sueño. Latencias del sueño aumentadas: 6/20. Eficiencia del sueño disminuidas en 4/20. Despertares nocturnos: promedio: 10.58. Expuestos a luz azul: 14/20. Horas exposición media: 2,4 hr/evento. Concluimos de este estudio que las principales dificultades fueron los despertares nocturnos con largos tiempo de vigilia, con disminución del tiempo total de sueño para la edad, y la actigrafía fue una herramienta de apoyo para objetivar conductas que dificultan la adquisición de un buen patrón de sueño.Palabras Clave: Insomnio infantil, sueño en lactantes, actigrafía, luz azul, despertares.
Abstract. Child insomnia is defined as sustained difficulty, despite the opportunity and according to age group, to initiate or maintain sleep, or a sleep quality causing that causes alterations in the child or family. It can significantly impact behavior, learning and metabolism of the child and his or her family, affecting their quality of life. The actigraphy through a device allows us to identify periods of wakefulness and sleep. The purpose of this work is to characterize sleep-wake patterns through actigraphy and to determine exposure to blue light in children younger than 2 years old, consulting for insomnia. An observational, descriptive, cross-sectional study of infants consulting for insomnia at the Sleep Center of UC Christus health network, in the period from March 2017 to 2018, with actigraphy. Twenty week long actigraphies were performed. The ages of the patients varied between 5 and 22 months, all had a diagnosis of insomnia that did not respond to initial management. Eight patients were male and 12 female. Hourly averages: bedtime: 8:31 PM. Waking up: 7:43 AM. Time variable for bedtime: 15/20. 10/20 NAPs after 16 hrs. All showed decreased sleep, with increases of total awake time once sleep began. Increased sleep latency: 6/20. Sleep efficiency decreased in 4/20. Nighttime Awakenings: average: 10.58. Exposed to blue light: 14/20. Average exposure in hours: 2.4 hr/event. We conclude from this study that the main difficulties were the nighttime awakenings with long time vigil, with decrease of the total sleep time for the age, and the actigraphy was a support tool to record behaviors that hinder a normal sleep pattern acquisition.Key words: Child insomnia, sleep in infants, actigraphy, blue light, awakenings

During the last years, a decline in the amount of hours of sleep has been observed in children. Sleep deficiency has been linked to an increase in calories, snacks, and fat intake. The objective of this study was to review the evidence between sleep duration and eating habits in children. We performed an electronic search in MEDLINE, The Cochrane Central Register, BIREME, EMBASE, LILACS, and Epistemonikos. Study selection criteria was: children aged 2-18 yrs within studies that aimed to associate sleep duration and eating habits. Quality of the included studies was assessed with the STROBE scale. Thirty studies were included, 10 in the metanalysis (n = 72,054). Odds ratio for unhealthy eating habits among children who had short sleep was OR 1.51 [95% CI: 1.24-1.85]. Snack consumption was associated with less sleep: OR 1.75 [95% CI 1.24-2.46]. The same figure for soda was OR 1.16 [CI 95% 1.09-1.25]. Adequate sleep duration was associated with intake of fruits and vegetables: OR 0.75 [CI 95% 0.65-0.86]. This systematic review showed an association between sleeping hours and eating habits in children. Education regarding sleep should be recommended in children in order to avoid unhealthy eating habits.
