Journal ArticleDOI
Eggs in Early Complementary Feeding and Child Growth: A Randomized Controlled Trial.
Lora Iannotti,Chessa K. Lutter,Christine P. Stewart,Carlos Andres Gallegos Riofrío,Carla Malo,Gregory Reinhart,Ana Palacios,Celia Karp,Melissa Chapnick,Katherine Cox,William F. Waters +10 more
TL;DR: It is shown that when offered early in complementary feeding, the food-based intervention of eggs produced a large effect size on child growth, supporting the hypothesis that early introduction of eggs significantly improved growth in young children.
Journal ArticleDOI
Generalized anxiety and sleep architecture: A polysomnographic investigation.
TL;DR: The sleep of 15 adult subjects who reported heightened generalized anxiety in the absence of other psychiatric syndromes and a 15-adult contrast group were studied, indicating disrupted sleep depth and continuity similar to that documented in clinical anxiety disorder patients and distinct from that of depressed patients.
Journal ArticleDOI
Short-term total sleep deprivations does not selectively impair higher cortical functioning.
TL;DR: Performance on an intelligence test, a test of sustained attention and tests designed to measure higher cortical function were compared in a group of 29 subjects who underwent 34-36 hours of continuous sleep deprivation and 32 normal sleeping control subjects and no significant group performance differences in the hypothesized direction were noted.
Journal ArticleDOI
Effects of Tyrosine, Phentermine, Caffeine d-amphetamine, and Placebo on Cognitive and Motor Performance Deficits During Sleep Deprivation
Richard A. Magill,William F. Waters,George A. Bray,Julia Volaufova,Steven R. Smith,Harris R. Lieberman,Nancy McNevin,Donna H. Ryan +7 more
TL;DR: It is concluded that all drugs tested improved at least some aspects of cognitive and motor performance after sleep deprivation, and tyrosine, a naturally occurring amino acid, may deserve further testing.
Journal ArticleDOI
The double burden of undernutrition and excess body weight in Ecuador
Wilma B. Freire,Katherine M Silva-Jaramillo,María J Ramírez-Luzuriaga,Philippe Belmont,William F. Waters +4 more
TL;DR: The coexistence of high rates of undernutrition and OW/OB at the individual, household, and national levels in Ecuador is shown, indicating that integrated approaches to address the emerging double burden are required.
