ABSTRACT
BACKGROUND: Administration of high-dose parenteral amino acids (AAs) to premature infants within hours of delivery is currently recommended. This study compared the effect of lower and higher AA administration starting close to birth on short-term growth and neurodevelopmental outcomes at 18-24 months corrected gestational age (CGA). METHODS: Infants <1250 g birth weight (n = 168) were randomly assigned in a blinded fashion to receive parenteral nutrition providing 1-2 g/kg/d AA and advancing daily by 0.5 g/kg/d to a goal of 4 g/kg/d (standard AA) or 3-4 g/kg/d and advancing to 4 g/kg/d by day 1. The primary outcome was neurodevelopmental outcomes measured by the Bayley Scales of Infant and Toddler Development, Third Edition at 18-24 months CGA. Secondary outcomes were growth parameters at 36 weeks CGA among infants surviving to hospital discharge, serum bicarbonate, serum urea nitrogen, creatinine, AA profiles in the first week of life, and incidence of major morbidities and mortality. RESULTS: No differences in neurodevelopmental outcome were detected between the high and low AA groups. Infants in the high AA group had significantly lower mean weight, length, and head circumference percentiles than those in the standard AA group at 36 weeks CGA and at hospital discharge. These differences did not persist after controlling for birth growth parameters, except for head circumference. Infants in the high AA group had higher mean serum urea nitrogen than the standard group on each day throughout the first week. CONCLUSION: Current recommendations for high-dose AA starting at birth are not associated with improved growth or neurodevelopmental outcomes.

OBJECTIVE: To describe the dietary behaviors of black women who enrolled in the SisterTalk weight control study. DESIGN: Baseline data collected via telephone survey and in-person screening. SETTING: Boston, Massachusetts and surrounding areas. PARTICIPANTS: 461 black women completed the baseline assessments. MAIN OUTCOME MEASURES: Measured height and weight; self-reported demographics, risk factors, and dietary variables including fat-related eating behaviors, food portion size, and fruit, vegetable, and beverage intake. ANALYSIS: Analysis of variance (ANOVA) models with food habits questionnaire (FHQ) scores as the dependent variable and demographic categories as the independent variables; ANOVA models with individual FHQ item scores as the dependent variable and ethnic identification as the independent variable. RESULTS: More than 60% reported eating < 5 servings of fruits and vegetables/day. Self-reported portion sizes were large for most food items. Older age, being born outside the United States, living without children, and being retired were significantly associated with a higher prevalence of fat-lowering behaviors. The frequency of specific fat-lowering behaviors and portion size also differed by ethnic identification. CONCLUSIONS AND IMPLICATIONS: The findings support the need for culturally appropriate interventions to improve the dietary intake of black Americans. Further studies should examine the dietary habits, food preparation methods, and portion sizes of diverse groups of black women.
