Breastfeeding and the anthropometric profile of children with sickle cell anemia receiving follow-up in a newborn screening reference service

AbstractObjectiveTo study the breastfeeding history (BF) and the anthropometric status of children with Sickle Cell Disease (SCD).MethodsA cross-sectional study of 357 children with SCD aged between 2 and 6 years, regularly followed at a Newborn Screening Reference Service (NSRS) between November 2007 and January 2009. The outcome was anthropometric status and the exposures were: BF pattern, type of hemoglobinopathy and child's age and gender.ResultsThe mean (SD) age was 3.7 (1.1) years, 52.9% were boys and 53.5% had SCA (hemoglobin SS). The prevalence of exclusive breastfeeding (EBR) up to six months of age was 31.5%, the median EBR times (p25-p75) was 90.0 (24.0-180.0) days and the median weaning ages (p25-p75) was 360.0 (90.0-720.0) days respectively. Normal W/H children experienced EBR for a mean duration almost four times longer than malnourished children (p=0.01), and were weaned later (p<0.05). Height deficit was found in 5.0% of children, while all the children with severe short stature had had SCA (hemoglobin SS) and were older than 4 years of age.ConclusionsEBF time and weaning age were greater than that found in the literature, which is a possible effect of the multidisciplinary follow-up. Duration of EBF and later weaning were associated with improved anthropometric indicators

Aleitamento materno e perfil antropométrico de crianças com doença falciforme acompanhadas em serviço de referência em triagem neonatal

Objetivo: descrever a história de aleitamento materno (AM) e estado antropométrico de crianças com doença falciforme (DF). Métodos: estudo transversal com 357 crianças com hemoglobinopatias SS e SC de dois e seis anos, acompanhadas regularmente num Serviço de Referência em Triagem Neonatal (SRTN) entre novembro de 2007 e janeiro de 2009. O desfecho correspondeu ao estado antropométrico e as exposições foram: padrão do AM, tipo de hemoglobinopatia, faixa etária e sexo da criança. Resultados: a média (DP) de idade observada foi de 3,7 (1,1) anos, 52,9% meninos e 53,5% com hemoglobinopatia SS. A prevalência de aleitamento materno exclusivo (AME) até o sexto mês foi de 31,5%, a mediana (p25-p75) do tempo de AME foi de 90 (24-180) dias e a mediana (p25-p75) da idade de desmame foi de 360 (90-720) dias. Crianças eutróficas em relação ao P/A tiveram o tempo de AME, em média, quase quatro vezes maior do que os desnutridos (p < 0,01), bem como foram desmamadas mais tarde (p < 0,05). O déficit de altura foi encontrado em 5% das crianças e todas as crianças com baixa estatura grave tinham hemoglobinopatia SS e mais de quatro anos. Conclusões: o tempo de AME e a idade de desmame foram superiores aos encontrados na literatura, possível efeito do acompanhamento multidisciplinar. A duração do AME e a idade mais tardia de desmame foram associadas a melhores indicadores antropométricos.Objective: to study the breastfeeding history (BF) and the anthropometric status of children with Sickle Cell Disease (SCD).
