Short Sleep Duration in the First Years of Life and Obesity/Overweight at Age 4 Years: A Birth Cohort Study.

OBJECTIVE: To investigate whether short sleep duration from the first year of life influenced weight at an early age. STUDY DESIGN: During 2004, children born in Pelotas, Brazil, were enrolled in a cohort study. Sleeping habits during the previous 2 weeks were assessed, and the children were weighed and measured at 1-, 2-, and 4-year follow-ups. Overweight and obesity at 4 years were defined according to World Health Organization z-scores for body mass index for age. Short sleep duration was defined as fewer than 10 hours of sleep per night at any follow-up. RESULTS: Out of the 4263 live births, 4231 were recruited. The prevalence of short sleep duration at any follow-up from 1-4 years of age was 10.1%. At 4 years of age, 201 children were obese (5.3%), and 302 (8%) were overweight. Among short sleepers, the prevalence ratio for overweight/obesity after adjusting for maternal and children's characteristics was 1.32 (1.03; 1.70). CONCLUSIONS: Children who slept for fewer than 10 hours per night at any follow-up from 1-4 years of age were more likely to be overweight or obese at 4 years of age, despite their sociodemographic and sleep characteristics.

Education in children's sleep hygiene: which approaches are effective? A systematic review, / Educação em higiene do sono na infância: quais abordagens são efetivas? Uma revisão sistemática da literatura,

Aim: To analyze the interventions aimed at the practice of sleep hygiene, as well as their applicability and effectiveness in the clinical scenario, so that they may be used by pediatricians and family physicians for parental advice. Source of data: A search of the PubMed database was performed using the following descriptors: sleep hygiene OR sleep education AND children or school-aged. In the LILACS and SciELO databases, the descriptors in Portuguese were: higiene E sono, educação E sono, educação E sono E crianças, e higiene E sono E infância, with no limitations of the publication period. Summary of the findings: In total, ten articles were reviewed, in which the main objectives were to analyze the effectiveness of behavioral approaches and sleep hygiene techniques on children's sleep quality and parents' quality of life. The techniques used were one or more of the following: positive routines; controlled comforting and gradual extinction or sleep remodeling; as well as written diaries to monitor children's sleep patterns. All of the approaches yielded positive results. Conclusions: Although behavioral approaches to pediatric sleep hygiene are easy to apply and adhere to, there have been very few studies evaluating the effectiveness of the available techniques. This review demonstrated that these methods are effective in providing sleep hygiene for children, thus reflecting on parents' improved quality of life. It is of utmost importance that pediatricians and family physicians are aware of such methods in order to adequately advise patients and their families. .

Objetivo: Avaliar as intervenções visando práticas de higiene do sono em crianças, sua aplicabilidade e efetividade na prática clínica, para que as mesmas possam ser utilizadas na orientação dos pais pelos pediatras e médicos de família. Fonte dos dados: Foi realizada busca na base de dados da Pubmed utilizando os descritores sleep hygiene OR sleep education AND child or school-aged, e nas bases Lilacs e Scielo, com as seguintes palavras-chave: higiene E sono, educação E sono, educação E sono E crianças, e higiene E sono E infância, não tendo sido limitado o período de busca. Síntese dos dados: Foram revisados 10 artigos cujos objetivos eram analisar efetividade de abordagens comportamentais e de técnicas de higiene do sono sobre a qualidade do sono das crianças e na qualidade de vida dos pais. Foram utilizadas uma ou mais das seguintes técnicas: rotinas positivas, checagem mínima com extinçcão sistemática e extinção gradativa ou remodelamento do sono, bem como diários do padrão de sono. Todas as abordagens apresentaram resultados positivos. Conclusões: Apesar de a abordagem comportamental no manejo do sono na faixa etária pediátrica ser de simples execuçcão e adesão, existem poucos estudos na literatura que avaliaram sua efetividade. Os estudos revisados evidenciaram que estas medidas são efetivas na higiene e refletem em melhoria na qualidade de vida dos pais. É de fundamental importância os pediatras e médicos de família conhecerem estas abordagens, para que possam oferecer orientacções adequadas a seus pacientes. .
