Breastfeeding Characteristics of Late-Preterm Infants in a Kangaroo Mother Care Unit

Infant growth by INTERGROWTH-21st and Fenton Growth Charts: Predicting 1-year anthropometry in South African preterm infants

Post-natal growth influences short- and long-term preterm infant outcomes. Different growth charts, such as the Fenton Growth Chart (FGC) and INTERGROWTH-21st Preterm Post-natal Growth Standards (IG-PPGS), describe different growth curves and targets. This study compares FGC- and IG-PPGS-derived weight-for-postmenstrual age z-score (WZ) up to 50 weeks postmenstrual age (PMA50) for predicting 1-year anthropometry in 321 South African preterm infants. The change in WZ from birth to PMA50 (ΔWZ, calculated using FGC and IG-PPGS) was correlated to age-corrected 1-year anthropometric z-scores for weight-for-age (WAZ), length-for-age (LAZ), weight-for-length (WLZ) and BMI-for-age (BMIZ), and categorically compared with rates of underweight (WAZ < -2), stunting (LAZ < -2), wasting (WLZ < -2) and overweight (BMIZ > + 2). Multivariable analyses explored the effects of other early-life exposures on malnutrition risk. At PMA50, mean WZ was significantly higher on IG-PPGS (-0.56 ± 1.52) than FGC (-0.90 ± 1.52; p < 0.001), but ΔWZ was similar (IG-PPGS -0.26 ± 1.23, FGC -0.11 ± 1.14; p = 0.153). Statistically significant ΔWZ differences emerged among small-for-gestational age infants (FGC -0.38 ± 1.22 vs. IG-PPGS -0.01 ± 1.30; p < 0.001) and appropriate-for-gestational age infants (FGC + 0.02 ± 1.08, IG-PPGS -0.39 ± 1.18; p < 0.001). Correlation coefficients of ΔWZ with WAZ, LAZ, WLZ and BMIZ were low (r < 0.45), though higher for FGC than IG-PPGS. Compared with IG-PPGS, ΔWZ < -1 on FGC predicted larger percentages of underweight (42% vs. 36%) and wasting (43% vs. 39%) and equal percentages of stunting (33%), while ΔWZ > + 1 predicted larger percentages overweight (57% vs. 38%). Both charts performed similarly in multivariable analysis. Differences between FGC and IG-PPGS are less apparent when considering ΔWZ, highlighting the importance of assessing growth as change over time, irrespective of growth chart.

The role of skin-to-skin contact in exclusive breastfeeding: a cohort study

OBJETIVE

To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth.

METHODS

A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study.

RESULTS

A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29–31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202–1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant’s weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%).

CONCLUSION

Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g–1,655g at birth, especially in those with lower severity scores.

Vulnerable mothers' experience of feeding their preterm infant in neonatal care

Background

Worldwide, preterm birth is a rising threat to maternal and child health. The universal challenges of being the mother of a preterm infant, combined with context-specific challenges such as poverty and poor linguistic and cultural representation, bring about risks for both mother and infant. This includes poor maternal mental health; poor mother–infant bonding and attachment and potential suboptimal developmental outcomes for the infant.

Objective

This article describes how Afrikaans-speaking mothers living in poverty experienced feeding their preterm infants in neonatal care.

Method

The study implemented a cross-sectional, qualitative design. Mothers of preterm infants (chronological ages between 3 and 6 months) were selected through a purposive sampling method and participated in individual semi-structured interviews. Nine interviews were thematically analysed. The participants were a vulnerable group, about whom little research literature was available.

Results

Feeding was perceived as a progressive task that worked towards the goal of discharge from the hospital. It was stressful because of various factors, but insufficient breastmilk supply was a significant contributor. The hospital setting was perceived as something that added to the participants’ anxiety surrounding feeding, but at the same time, it had the potential to decrease their anxiety. When the mother–infant dyad was able to breastfeed successfully, it made the participants feel like mothers at last after an extended period of anticipation.

Conclusion

Feeding their preterm infant was a prominent experience for the mothers, especially whilst in neonatal care. Increased feeding support is required from the healthcare team providing neonatal care in order to optimally use the neonatal period.

Maternal experience of intermittent kangaroo mother care for late preterm infants: a mixed-methods study in four postnatal wards in China

OBJECTIVE

To describe how mothers of late preterm infants experienced the provision of intermittent kangaroo mother care (KMC) in four postnatal wards in different hospitals in China, under a pilot KMC project.

DESIGN

A concurrent mixed-methods approach incorporating quantitative maternal questionnaires and qualitative semistructured interviews.

SETTING

Four postnatal wards in level-III hospitals based in different provinces of Southeast and Northwest China.

PARTICIPANTS

All 752 mothers who provided intermittent KMC to their late preterm newborns in the four participating postnatal wards consented to participate in the study (quantitative component), as well as six nurses, two obstetricians and two mothers from two of the participating postnatal wards (qualitative component).

OUTCOME MEASURES

Maternal KMC experiences during a hospital stay, patients' perceptions of KMC initiation, processes, benefits and challenges.

RESULTS

Most mothers had not heard of KMC before being introduced to it in the postnatal ward. On average, mothers and newborns stayed in postnatal wards for 3.6 days; during their stay, mothers provided an average of 3.5 KMC sessions, which is an average of 1.1 sessions a day. Each KMC session lasted an average of 68 min, though there was much variation in the length of a session. Common reasons given for discontinuing a KMC session included restroom use, infant crying and perceived time limitations. Some mothers would have preferred to provide KMC for longer periods of time and nurses encouraged this. Most mothers experienced no difficulty providing KMC, received support from family and medical staff and intended to continue with KMC postdischarge.

CONCLUSION

In order to improve the maternal experience of KMC, it is recommended that raising awareness of KMC should be included in antenatal care and after birth. Longer periods of KMC provision should be encouraged, greater privacy should be provided for mothers providing KMC in postnatal wards and family members should be encouraged to support KMC.

Breastfeeding Outcomes, Self-Efficacy, and Satisfaction Among Low-Income Women With Late-Preterm, Early-Term, and Full-Term Infants

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.

Intermittent kangaroo mother care and the practice of breastfeeding late preterm infants: results from four hospitals in different provinces of China

BACKGROUND

China has an extremely low exclusive breastfeeding rate. Kangaroo mother care (KMC) has been shown to increase the exclusive breastfeeding rate among infants born extremely or very preterm. However, there is limited evidence surrounding intermittent KMC and exclusive breastfeeding in late preterm infants. In our study we investigated the association between the provision of intermittent KMC and breastfeeding practice for late preterm infants in four hospitals in different provinces of China.

METHODS

Intermittent KMC was recommended to the mothers of all preterm infants admitted to the postnatal wards of participating hospitals between March 2018 and March 2019. Those who agreed to practice KMC were enrolled in the "KMC group", those who did not were enrolled in the "No KMC group". Basic maternal socio-demographic information was collected, feeding practice; outcome and method, were recorded daily whilst in hospital. A follow-up survey of feeding practice was conducted 42 days after discharge. Calculations for feeding practice were performed separately for both groups. Logistics regression was used to analyze the association between KMC and feeding outcome and method, adjusting for socio-demographic covariates.

RESULTS

Among the 844 mothers participating in the study, 627 (74.3%) chose to perform KMC. More of the mothers who provided KMC were exclusively breast milk feeding their infants in the 24 h before hospital discharge (54.6%) and at follow-up (57.3%), compared to mothers who did not provide KMC (34.6% at discharge and 33.2% at follow-up,). Mothers in the KMC group were more likely to be breastfeeding (method) than mothers in the No KMC group (65.3% vs. 52.1% at discharge, and 83.1% vs. 67.3% at follow up). Logistic regression indicated that compared with the No KMC group, mothers who provided KMC were twice as likely to be exclusively breast milk feeding their infants at discharge (OR = 2.15 (95% CI 1.53, 3.02)), use breastfeeding method at discharge as opposed to other means such as bottle or cup feeding (OR = 1.61 (95% CI 1.15, 2.25)), be exclusive breast milk feeding at follow-up (OR = 2.55 (95% CI 1.81, 3.61)), and use breastfeeding method at follow-up (OR = 2.09 (95% CI 1.44, 3.02)).

CONCLUSIONS

Intermittent KMC was associated with a nearly doubled increase in exclusive breast milk feeding (outcome) and breastfeeding (method) at both discharge and 42 days after discharge for late preterm infants. This is especially important in China where exclusive breastfeeding rates are low, intermittent KMC provides a feasible means to increase the likelihood of these vulnerable infants receiving the benefits of exclusive breastmilk.
