          Abstract

          INTRODUCTION: Infants with a risk indicator of hearing loss (RIHL) are more likely to have delays in their development. Besides the biological risk, the infant's environment may determine the outcome of their development. OBJECTIVE: To compare the motor, cognitive and language development of infants with and without RIHL and to know the affordances of the home environment of those infants. METHODS: This was an observational research exploratory, cross-sectional and quantitative study, in which the development of 77 infants with RIHL (Study Group) were compared to 77 infants without RIHL (Compared Group). Cognition, language and motricity were evaluated according to the Bayley Scale of Infant Development, and the home environment according to the Affordability of the Home Environment for Motor Development - Baby Scale questionnaire. RESULTS: The most frequent risk indicators were family history (25.6%) and hyperbilirubinaemia (24.4%). In the Study Group, 13 (16.8%) infants presented delays in at least one domain and in the Control Group 3 (3.9%) infants presented delays. There was a statistically significant difference in the motor (p = 0.0001), cognitive (p = 0.001) and language (p = 0.0304) domains, with a better score in the Control Group. Regarding the home environment, 70.2% of houses in the Study Group were classified as less than adequate or mildly adequate, while in the Control Group this was 50.7%. CONCLUSION: The average development of the infants with risk indicators for hearing loss is below the average development of infants without them. Also, the number of environments below adequate is higher in the group with infants with risk indicators.

          INTRODUÇÃO: Lactentes com indicadores de risco para deficiência auditiva (IRDA) têm maior probabilidade de apresentar atrasos do desenvolvimento. Além dos indicadores de risco biológicos, o ambiente em que o lactente está inserido pode determinar o desfecho do desenvolvimento infantil. OBJETIVO: Comparar o desenvolvimento motor, cognitivo e de linguagem de lactentes com e sem indicadores de risco para deficiência auditiva e conhecer as affordances no ambiente domiciliar dos lactentes com e sem indicadores de risco. MÉTODO: Pesquisa observacional exploratória, transversal e quantitativa, na qual o desenvolvimento de 77 lactentes com IRDA (GE- Grupo de Estudo) foi comparado ao de 77 lactentes sem os indicadores (GC- Grupo Comparado). Avaliou-se a cognição, linguagem e motricidade por meio das Escalas Bayley de Desenvolvimento Infantil e o ambiente domiciliar pelo questionário Affordances no Ambiente Domiciliar para o Desenvolvimento Motor - Escala Bebê. RESULTADOS: Os indicadores de risco mais frequentes foram histórico familiar (25,6%) e hiperbilirrubinemia (24,4%). No GE, 13 (16,8%) dos lactentes apresentaram atrasos em pelo menos um domínio do desenvolvimento e no GC 3 lactentes (3,9%). Houve diferença estatisticamente significativa nos domínios motor (p = 0,0001), cognitivo (p = 0,001) e de linguagem (p = 0,0304), com melhor desempenho no GC. Quanto ao ambiente domiciliar, 70,2% dos domicílios do GE classificou-se em "Menos que o adequado" ou "Moderadamente adequado", enquanto no GC o valor foi de 50,7%. CONCLUSÃO: O desenvolvimento médio dos lactentes com IRDA está abaixo comparado aos lactentes sem indicadores e o número de ambientes abaixo do esperado é maior no grupo de lactentes com IDRA

          Underestimation of developmental delay by the new Bayley-III Scale.

          To assess the ability of the third edition of the Bayley Scales of Infant and Toddler Development (Bayley-III) to detect developmental delay in 2-year-old children who were extremely preterm and those carried to term. Prospective cohort study. The state of Victoria, Australia. Subjects were consecutive surviving children who were born either at less than 28 weeks' gestational age (extremely preterm) or with less than 1000 g birth weight (extremely low-birth-weight; n = 221) in the state of Victoria, Australia, in 2005 and randomly selected controls who were both carried to term and of normal birth weight (n = 220). Children were assessed by psychologists blinded to knowledge of group at 2 years of age, corrected for prematurity with the new Bayley-III scale. Follow-up rates of both cohorts were high (>92%). Mean values for all composite and subtest scores for the extremely preterm/extremely low-birth-weight group were significantly below those of the control group (P < .001), with the magnitude of all group differences being in excess of two-thirds SD. Mean values for the extremely preterm/extremely low-birth-weight group approached the normative mean, but in contrast, the mean values for the control group were higher than expected, with composite scores being between 0.55 and 1.23 SD above the normative mean. Proportions of children with developmental delay were grossly underestimated using the reference values, but were within the expected range when computed relative to the mean (standard deviation) for the controls. The Bayley-III scale seriously underestimates developmental delay in 2-year-old Australian children.

            Multiprofessional committee on auditory health – COMUSA

            Created in 2007, COMUSA is a multiprofessional committee comprising speech therapy, otology, otorhinolaryngology and pediatrics with the aim of debating and countersigning auditory health actions for neonatal, lactating, preschool and school children, adolescents, adults and elderly persons. COMUSA includes representatives of the Brazilian Audiology Academy (Academia Brasileira de Audiologia or ABA), the Brazilian Otorhinolaryngology and Cervicofacial Surgery Association (Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico Facial or ABORL), the Brazilian Phonoaudiology Society (Sociedade Brasileira de Fonoaudiologia or SBFa), the Brazilian Otology Society (Sociedade Brasileira de Otologia or SBO), and the Brazilian Pediatrics Society (Sociedade Brasileira de Pediatria or SBP).

              Does the Bayley-III Motor Scale at 2 years predict motor outcome at 4 years in very preterm children?

              To assess the predictive validity of the Bayley Scales of Infant and Toddler Development - Third Edition (Bayley-III) for later motor outcome. Ninety-six infants (49 males, 47 females) born at less than 30 weeks' gestation admitted to two tertiary hospitals in Melbourne, Australia, were assessed with the Bayley-III Motor Scale at 2 years' corrected age and were classified as suspect or definite motor impairment if they scored less than -1 or -2 standard deviations respectively, relative to the test mean. At 4 years' corrected age, children completed Movement Assessment Battery for Children - Second Edition (MABC-2); for the total motor score, cut-offs of not more than the 15th were used to classify motor development and cut-offs of not more than the 15th centile were classified as having a significant movement difficulty. Of the 96 children assessed at both ages, at 2 years 9% had suspect and 4% had definite motor impairment; however, by 4 years, rates had increased to 22% and 19% respectively. The specificity of the Bayley-III for motor impairments for later motor outcome was excellent (ranging from 94 to 100% for cerebral palsy [CP] and 97 to 100% for motor impairment), although the sensitivity was low (ranging from 67 to 83% for CP and 18 to 37% for motor impairment); many children with later impairment were not identified by the Bayley-III. The Bayley-III Motor Scale at 2 years underestimates later rates of motor impairment, particularly in the absence of CP at 4 years on the MABC-2 total motor score in children born at less than 30 weeks' gestational age. © The Authors.
