Early Hum Dev 2023; 177-178:105730. [PMID: 36822127 DOI: 10.1016/j.earlhumdev.2023.105730] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 02/11/2023] [Accepted: 02/12/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND Feeding mother's own milk (MOM) is associated with reduced morbidity of very low birth weight (VLBW) infants (<1500 g), but not all mothers are able to provide pumped breast milk or breastfeed until discharge. AIMS To investigate the duration of MOM feeding and identify risk factors for cessation. STUDY DESIGN Single-center retrospective cohort study. SUBJECTS 307 VLBW infants born 2012 and 2019 surviving beyond 7 days of life. OUTCOME MEASURES Analysis of MOM feeding at discharge, including comparison with a historical cohort of infants born 1992-1994. RESULTS MOM feeding was initiated in 178/180 infants (98.9 %) born in 2012 and in 123/127 infants (96.9 %) born in 2019 (p = 0.132), as compared to 73/89 (82 %) infants born 1992-1994 (p < 0.001). Median [range] duration of MOM feeding was similar for infants born in 2012 (45 [0-170] days) and 2019 (50 [0-190] days) (p = 0.396), but much longer than in the historical cohort (36 [0-152] days) (p < 0.001). The overall breastfeeding rate increased up to 69.2 % and 77.2 %. Factors associated with cessation of MOM feeding were smoking during pregnancy, single-mother status, short (<12 years) duration of maternal or paternal school education (all p ≤ 0.001), natural conception, birth weight ≥ 1000 g, and gestational age ≥ 29 weeks (p < 0.05). In Cox proportional hazard multivariate analysis, smoking during pregnancy and single-mother status remained independent risk factors. CONCLUSIONS Duration of MOM feeding and breastfeeding rates of VLBW infants during hospital stay have increased significantly during the last 30 years, while smoking and indicators of low socioeconomic status remain dominant predictors of cessation of MOM feeding.

Thirdhand smoke associations with the gut microbiomes of infants admitted to a neonatal intensive care unit: An observational study. ENVIRONMENTAL RESEARCH 2021; 197:111180. [PMID: 33865820 PMCID: PMC8187318 DOI: 10.1016/j.envres.2021.111180] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 04/06/2021] [Accepted: 04/08/2021] [Indexed: 05/05/2023]
Abstract
INTRODUCTION Microbiome differences have been found in adults who smoke cigarettes compared to non-smoking adults, but the impact of thirdhand smoke (THS; post-combustion tobacco residue) on hospitalized infants' rapidly developing gut microbiomes is unexplored. Our aim was to explore gut microbiome differences in infants admitted to a neonatal ICU (NICU) with varying THS-related exposure. METHODS Forty-three mother-infant dyads (household member[s] smoke cigarettes, n = 32; no household smoking, n = 11) consented to a carbon monoxide-breath sample, bedside furniture nicotine wipes, infant-urine samples (for cotinine [nicotine's primary metabolite] assays), and stool collection (for 16S rRNA V4 gene sequencing). Negative binomial regression modeled relative abundances of 8 bacterial genera with THS exposure-related variables (i.e., household cigarette use, surface nicotine, and infant urine cotinine), controlling for gestational age, postnatal age, antibiotic use, and breastmilk feeding. Microbiome-diversity outcomes were modeled similarly. Bayesian posterior probabilities (PP) ≥75.0% were considered meaningful. RESULTS A majority of infants (78%) were born pre-term. Infants from non-smoking homes and/or with lower NICU-furniture surface nicotine had greater microbiome alpha-diversity compared to infants from smoking households (PP ≥ 75.0%). Associations (with PP ≥ 75.0%) of selected bacterial genera with urine cotinine, surface nicotine, and/or household cigarette use were evidenced for 7 (of 8) modeled genera. For example, lower Bifidobacterium relative abundance associated with greater furniture nicotine (IRR<0.01 [<0.01, 64.02]; PP = 87.1%), urine cotinine (IRR = 0.08 [<0.01,2.84]; PP = 86.9%), and household smoking (IRR<0.01 [<0.01, 7.38]; PP = 96.0%; FDR p < 0.05). CONCLUSIONS THS-related exposure was associated with microbiome differences in NICU-admitted infants. Additional research on effects of tobacco-related exposures on healthy infant gut-microbiome development is warranted.
