Randomized Controlled Trial Multicenter Study Clinical Trial
Food group sources of nutrients in the dietary patterns of the DASH-Sodium trial.
The aim of this paper is to identify major food group sources of several essential nutrients in the two dietary patterns used in the DASH-Sodium trial: a control diet and the DASH dietary pattern. The DASH-Sodium trial was a multicenter, randomized, controlled-feeding trial comparing the effects of three levels of sodium and two dietary patterns on blood pressure. Nutrient contents of all the menus for both the control and the DASH diets were analyzed and examined for their dietary sources from 13 food groups. ⋯ The DASH dietary pattern recommends four to five servings of fruits; four to five servings of vegetables; two to three servings of low-fat dairy products; seven to eight servings of grain products (preferably whole grains); two or less servings of meats, poultry, and fish per day; and four to five servings of nuts, seeds, and legumes per week for a 2,000 kcal diet. Each of these food groups contributes critical nutrients across various sodium levels. It is important to emphasize all food groups when trying to follow this proven dietary pattern.

Development of a method using marketing research data to assess food purchase behavior and consequent nutrient availability for purposes of nutrition surveillance, evaluation of intervention effects, and epidemiologic studies of diet-health relationships. ⋯ Purchase records from large, nationally representative panels of shoppers, such as those maintained by major market research companies, might be used to accomplish detailed longitudinal epidemiologic studies or surveillance of national food- and nutrient-purchasing patterns within and between countries and segments of their respective populations.

Comparative Study
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.

This study explored a relationship between professional involvement and job satisfaction among dietitians. A random sample of 2,600 employed registered dietitians (RDs) received a 55-item questionnaire including a standardized measure of job satisfaction. The response rate was 67.3%; 50.8% were useable (n = 1,321). ⋯ Additionally, six characteristics related to professional involvement were: having had a mentor, being a mentor, self-assessed high professional involvement, full-time employment, high annual income, and increased hours worked per week. There was also a positive relationship between markers of professional involvement and employer support. We conclude that, overall, RDs are satisfied with their jobs and that greater professional involvement is related to greater job satisfaction.

Comparative Study
Comparison of energy prediction equations with measured resting energy expenditure in children with sickle cell anemia.
To determine the accuracy of energy prediction equations when compared with measured resting energy expenditure (REE) in children with sickle cell anemia. To develop a modified equation that more accurately estimates the energy needs of children with sickle cell anemia and to cross-validate these on a different set of patients (test patients). ⋯ Both energy prediction equations underestimated REE in children with sickle cell anemia. The 2 modified versions of the energy prediction equations that we propose predicted the energy needs of these children much more accurately; however, the modified equations need to be validated through application to other children with sickle cell anemia.
