Eating difficulties in girls with Rett syndrome compared with other developmental disabilities.
Rett syndrome arises from a mutation on the X chromosome and occurs with prevalence in the general population in 1:10,000 women. Its major nutritional consequences require that health providers recognize early signs of eating difficulties and slowing of growth parameters. Retrospective record review of 44 girls, in two equal-sized groups matched by age, showed that the Rett syndrome group was significantly different, with lower body weights, more respiratory difficulties, more gastrointestinal symptoms interfering with eating, more swallowing problems, less self-feeding, and lower texture tolerance for chewy and crunchy foods compared with the developmental disability group. ⋯ Detailed food intake information was analyzed for food texture characteristics to recognize early eating and texture tolerance problems. Recommendations were offered for conducting a thorough nutrition assessment of Rett syndrome patients, including analysis of the texture of consumed foods. Additional recommendations for improving nutrition services to those with Rett syndrome and other developmental disabilities include ruling out microcephaly, early identification of eating difficulties, with modifications in food texture as appropriate, and self-feeding goals.
