BACKGROUND: Registered dietitian nutritionists are trained to identify optimal food choices for clients based on medical state and lifestyle. Orthorexia nervosa (ON) is a proposed disorder related to obsessions about eating healthfully. Eating disorders (EDs) are serious mental illnesses with symptoms related to eating, body image, and self-esteem. Both ON and EDs are more common among RDNs than the general population. OBJECTIVE: This study examined the prevalence of ON and EDs in RDNs in the United States and, among this sample, assessed whether the presence of ON symptoms related to symptoms of EDs, including weight, shape, eating, and restraint...

BACKGROUND: While school foods have become healthier under the Healthy, Hunger Free Kids Act, research suggests there is still substantial food waste in cafeterias. It is therefore necessary to study factors that can impact food consumption, including holding recess before lunch ("reverse recess") and starting lunch periods very early or very late. OBJECTIVE: This study examined the association between the timing of recess (pre-lunch vs post-lunch recess), the timing of the lunch period, and food consumed by students at lunch...

Julie T Schaefer, Melissa D Zullo
BACKGROUND: Researchers have been advocating for a new weight-inclusive paradigm that focuses on health rather than weight. One important component of this model is intuitive eating. Although registered dietitian nutritionists (RDNs) are the nation's food and nutrition experts, RDNs' knowledge of and attitudes toward intuitive eating and use of traditional or restrictive strategies are unknown. OBJECTIVE: The purpose of this study was to characterize RDNs' knowledge of and attitudes toward an intuitive eating lifestyle and describe use of traditional weight management and nonrestrictive lifestyle practices with clients...

Confidence is frequently used to assess practitioner effectiveness, and its evaluation requires valid and reliable domain-specific tools. However, the quality of existing measures is unknown. This review identifies studies measuring dietitians' confidence in working with individuals; assesses psychometric (measurement) qualities of relevant tools; and identifies areas for future research. Seven electronic databases, the internet, and reference lists were searched to identify the development or use of relevant confidence measurement scales...

BACKGROUND: Few studies have been conducted in rural areas assessing the influence of community-level environmental factors on residents' success improving lifestyle behaviors. OBJECTIVE: Our aim was to examine whether 6-month changes in diet, physical activity, and weight were moderated by the food and physical activity environment in a rural adult population receiving an intervention designed to improve diet and physical activity. DESIGN: We examined associations between self-reported and objectively measured changes in diet, physical activity, and weight, and perceived and objectively measured food and physical activity environments...

BACKGROUND: Glycemic index (GI) and glycemic load (GL) may be implicated in acne pathogenesis. OBJECTIVE: This cross-sectional study examined differences between GI/GL and biological factors associated with acne among adults with and without moderate/severe acne. Secondary objectives included examining differences between food-aggravated acne beliefs and acne-specific quality of life among adults with and without moderate/severe acne. DESIGN: As part of a cross-sectional study, participants completed a 5-day food record; blood draw to measure biological factors associated with acne (ie, glucose, insulin, insulin-like growth factor-1, insulin-like growth factor binding protein-3, and sex hormone-binding globulin concentrations); body composition assessment; and questionnaire to evaluate food-aggravated acne beliefs and acne-specific quality of life...

Hypertension (HTN) or high blood pressure (BP) is among the most prevalent forms of cardiovascular disease and occurs in approximately one of every three adults in the United States. The purpose of this Evidence Analysis Library (EAL) guideline is to provide an evidence-based summary of nutrition therapy for the management of HTN in adults aged 18 years or older. Implementation of this guideline aims to promote evidence-based practice decisions by registered dietitian nutritionists (RDNs), and other collaborating health professionals to decrease or manage HTN in adults while enhancing patient quality of life and taking into account individual preferences...

#13
Douglas C Chang, Paolo Piaggi, Jonathan Krakoff
BACKGROUND: Accurate prediction of 24-hour energy expenditure (24EE) relies on knowing body composition, in particular fat-free mass (FFM), the largest determinant of 24EE. FFM is closely correlated with hematologic volumes: blood volume (BV), red cell mass (RCM), and plasma volume (PV). However, it is unknown whether predicted hematologic volumes, based on easily collected variables, can improve 24EE prediction. OBJECTIVE: The aim was to develop and validate equations to predict 24EE based on predicted BV, RCM, and PV and to compare the accuracy and agreement with models developed from FFM and with the Mifflin-St Jeor equation, which is recommended for clinical use by the Academy of Nutrition and Dietetics...

BACKGROUND: Prenatal supplements are often recommended to pregnant women to help meet their nutrient needs. Many products are available, making it difficult to choose a suitable supplement because little is known about their labeling and contents to evaluate their appropriateness. OBJECTIVE: To determine differences between prescription and nonprescription prenatal supplements available in the United States regarding declared nutrient and nonnutrient ingredients and the presence of dosing and safety-related information...
