RESUMEN
This study aimed to evaluate the association between maternal gestational Vitamin D3 supplementation and early respiratory health in offspring. This was a population-based record-linkage study which used data from the French National Health Database System. Maternal Vitamin D3 supplementation consisted of a single high oral dose of cholecalciferol, (100,000 IU) from the seventh month of pregnancy, according to national guidelines. In total, 125,756 term-born singleton children were included, of which 37% had respiratory illness defined as hospital admission due to respiratory causes or inhalation treatment up to 24 months of age. Infants prenatally exposed to maternal Vitamin D3 supplementation (n = 54,596) were more likely to have a longer gestational age (GA) at birth (GA 36-38 weeks, 22% vs. 20%, p < 0.001 in exposed vs. non-exposed infants, respectively). After adjusting for the main risk factors (maternal age, socioeconomic level, mode of delivery, obstetrical and neonatal pathology, birth weight appropriateness, sex, and birth season), the risk of RD was found to be 3% lower than their counterparts (aOR [IC 95%], 0.97 [0.95-0.99], p = 0.01). In conclusion, this study provides evidence for the association between maternal gestational Vitamin D3 supplementation and improved early respiratory outcomes in young children.

Background: Late preterm infants (LPIs; born at 340/7 to 366/7 gestational weeks) and early term infants (ETIs; 370/7 to 386/7 gestational weeks) are at higher risk of morbidity and mortality compared with more mature infants. Breastfeeding can reduce these risks, but feeding difficulties are common among these infants and breastfeeding rates are low. We conducted a systematic review to identify the interventions available to improve any breastfeeding, exclusive breastfeeding, or breast milk yield. Methods: A literature search was performed up to February 23, 2022, using MEDLINE, CINAHL, Embase, and Google Scholar, and nine articles were included. Only one article was a randomized controlled trial, and only one included ETIs. The remaining articles were quasi-experimental and included only LPIs. Outcomes included breastfeeding duration, breastfeeding exclusivity, and/or breast milk production (volume) before 6 months actual age. Results: Professional support significantly improved exclusive breastfeeding rates. A breastfeeding education program delivered at the hospital with weekly telephone follow-up postdischarge significantly increased breastfeeding rates. Neither cup feeding nor early discharge (with in-home lactation support) improved breastfeeding rates, whereas rooming-in (versus direct admission to the neonatal intensive care unit) worsened exclusive breastfeeding rates. Discussion: This is the first systematic review to identify interventions available for both LPIs and ETIs. Overall, there are limited studies that investigate interventions promoting breastfeeding in these populations. However, breastfeeding support delivered by health care professionals seems to improve breastfeeding rates. The main limitations are the lack of randomization, blinding, and adjustment for confounding variables. Experimental studies with robust methodological design are needed.

OBJECTIVE: To assess breastfeeding exclusivity and rate of breastfeeding, breastfeeding self-efficacy, and satisfaction with breastfeeding after hospital discharge among low-income women with late-preterm and early-term infants compared with women with full-term infants. DESIGN: Prospective, comparative, with repeated measures. SETTING: Four Midwestern U.S. Special Supplemental Nutrition Program for Women, Infants, and Children offices. PARTICIPANTS: Participants included 270 mother-infant dyads. METHODS: We assessed breastfeeding exclusivity, rate of breastfeeding, and breastfeeding self-efficacy at 2 weeks, 2 months, and 5 months and satisfaction with breastfeeding at 5 months after birth or when participants stopped breastfeeding. RESULTS: More than 50% of women in each subgroup were non-Hispanic White. Late-preterm and early-term infants had lower breastfeeding exclusivity rates than full-term infants across the three time points (40%, 51%, and 65% at 2 weeks, p = .029; 22.5%, 34%, and 58% at 2 months, p < .001; and 7%, 15%, and 28.46% at 5 months, p < .001, respectively). The overall exclusive breastfeeding rate for all groups was 55.93% at 2 weeks, 44.07% at 2 months, and 20.37% at 5 months; 55.56% continued any breastfeeding at 5 months. Breastfeeding self-efficacy during the first 5 months after birth, satisfaction with breastfeeding, level of education, and attending breastfeeding classes were positively correlated with breastfeeding exclusivity. We found significantly less exclusive breastfeeding, lower breastfeeding self-efficacy, and lower satisfaction with breastfeeding among participants with late-preterm and early-term infants compared to those with full-term infants. CONCLUSION: Ongoing professional breastfeeding support for women is needed to improve and promote breastfeeding exclusivity and continuation among their late-preterm and early-term infants.

Objective: To examine breastfeeding exclusivity and intensity of early term (ET) infants, born at 37-38 weeks, and term infants, born at 39-41 weeks, during the postpartum hospitalization and the first month of life. Materials and Methods: This was a prospective cohort study of 358 mothers of ET and term infants during the first 72 hours after birth and at 1 month of age. Logistic analysis was used to calculate unadjusted and adjusted odds ratios (aORs) and control for confounding variables. Results: ET infants had significantly lower breastfeeding in the first hour (aOR = 0.43, 95% confidence interval [CI] = 0.21-0.87), lower exclusive breastfeeding in the hospital and at 1 month (aOR = 0.46, 95% CI = 0.27-0.71 and aOR = 0.40, 95% CI = 0.22-0.71), and lower rates of high breastfeeding intensity in the hospital and at 1 month (aOR = 0.39, 95% CI = 0.22-0.71 and aOR = 0.33, 95% CI = 0.15-0.72), after controlling for confounding variables. ET infants had more emergency room (ER) visits in the first month (OR = 7.6, 95% CI = 1.01-60.6), and all ET infants who had ER visits were exclusively breastfed. Conclusions: ET infants had lower breastfeeding in the hospital and at 1 month. They should be regarded as a group at risk for breastfeeding challenges and infant morbidity.
