Pediatr Res 2025; 97:1085-1089. [PMID: 39034355 DOI: 10.1038/s41390-024-03406-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 06/03/2024] [Accepted: 06/27/2024] [Indexed: 07/23/2024]
Abstract
OBJECTIVE Racism leads to disparities in health outcomes. Our objective was to determine if black race was independently associated with differences in fat accretion at discharge in a large cohort of very preterm infants (32 weeks of gestation or less). METHODS De-identified demographic, anthropometric and body composition data were collected from seven neonatal units around the United States. Weight, length, and head circumference z-scores at birth and at the time of body composition assessment or hospital discharge were calculated. RESULTS The median gestational age and birthweight for this cohort (n = 888) were 29 weeks [IQR, 27-30] and 1167 g [SD, 354], respectively. The study population included 53% black preterm infants. Birthweight was lower in black preterm infants compared with white infants (1112 ± 334 g vs. 1228 ± 366 g; p < 0.0001). After adjusting for birthweight, gestational age, and birthweight-for-age z-score, black preterm infants had more weight gain (adjusted mean difference: 0.5 g/kg/day; p = 0.03) but not higher BF% z-scores at hospital discharge (adjusted mean: 1.2 vs. 1.3; p = 0.14) than white infants. CONCLUSIONS After adjusting for covariates, black race was associated with higher weight gain velocity but not higher BF% z-scores. IMPACT This study presents findings from a large-scale multicenter cohort. Racial differences were observed in birth weight and the rate of weight gain; however, these differences were not associated with dissimilarities in body composition outcomes. Understanding nutrition and growth outcomes across racial groups is necessary to combat racial disparities in the neonatal intensive care unit (NICU).

[PMID: 36737570 PMCID: PMC9991910 DOI: 10.1038/s41372-023-01612-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 01/09/2023] [Accepted: 01/13/2023] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To identify racial/ethnic disparities in postnatal growth by year and gestational age among very low birth weight infants. STUDY DESIGN Total 37,122 infants, with birth weight 500-1500 g or gestational age 23-34 weeks in the California Perinatal Quality Care Collaborative in 2008-2016. Postnatal growth failure (PGF) was defined as change in weight Z-score from birth to discharge below -1.28. Multivariable regression analysis with birth hospital as random effect was used to estimate odds ratios (OR). RESULTS Infants born to Hispanic mothers had highest risk of PGF at 30%, compared to white (24%, OR 1.33), Black (22%, OR 1.50), or Asian/Pacific Islander mothers (23%, OR 1.38). PGF incidence decreased from 2008 (27.4%) to 2016 (22.8%) with differences in trends by race. Each increasing gestational age week was associated with decreasing risk for PGF (OR 0.73, 95% confidence interval 0.72-0.74). CONCLUSION Targeted interventions addressing PGF are needed to address disparities.
