Effect of community‐initiated kangaroo mother care on breastfeeding performance in low birthweight infants: A randomized clinical trial

This individually randomized trial was conducted to estimate the effect of promoting community‐initiated kangaroo mother care (ciKMC) in low birthweight (LBW) infants on infant breastfeeding performance. It was designed as a substudy within a larger primary trial on ciKMC and infant survival. Five hundred fifty stable LBW mother‐infant dyads (1500−2250 g) who provided consent, were consecutively enroled for breastfeeding performance assessment. The ciKMC intervention included promotion and support of continuous skin‐to‐skin contact and exclusive breastfeeding (EBF) through home visits during the neonatal period. The primary outcome was effective breastfeeding performance indicated by an infant breastfeeding assessment tool score of ≥10 after the end of the neonatal period. As secondary outcomes, we reported maternal satisfaction related to infant breastfeeding, and EBF after the end of the neonatal period. We completed outcome assessments in 96% of participants. In the ciKMC arm, 92% of the infants showed effective breastfeeding performance against 81% in the control arm [adjusted prevalence ratio (aPR): 1.24, 95% confidence interval (CI): 1.16−1.32]. In the ciKMC arm, 65% of the mothers reported to be very satisfied with their infants'' breastfeeding against 51% in the control arm (aPR: 1.22, 95% CI: 1.05−1.41). The proportion of infants practicing EBF was 89% in the ciKMC arm against 45% in the control arm (aPR: 1.62, 95% CI: 1.45−1.81). Our study findings suggest that promotion of ciKMC can improve effective breastfeeding, EBF and maternal satisfaction related to breastfeeding in LBW infants.     

Early cessation of breast milk feeding in very low birthweight infants

This investigation was carried out to comparatively assess the duration of breast milk feeding and to analyze risk factors for early cessation of breast milk feeding in term and very preterm infants. A cohort study was performed in 89 consecutive very low birthweight (VLBW) infants (<1500 g) who survived for at least for one week, and 177 term infants with birthweights >2500 g born in the same hospital matched for gender and multiplicity. Median duration of breast milk feeding, as determined from charts and questionnaires mailed to the mothers at 6 and 12 months corrected age, was 36 days in VLBW infants, compared to 112 days in control infants (P<0.0001). In both VLBW and control infants, smoking during pregnancy, low maternal and low paternal school education were each significantly associated with short duration of breast milk feeding. In VLBW infants, multiple pregnancy and gestational age <29 weeks were each associated with prolonged breast milk feeding, as were maternal age >35 years and spontaneous pregnancy (as opposed to pregnancy following infertility treatment) in term infants. Multivariate analysis revealed that VLBW, smoking and low parental school education were independent negative predictors of breast milk feeding. While these results emphasize the need for special support of VLBW infant mothers promoting lactation, the relationships between smoking, school education and breast milk feeding in both strata show that efforts to increase breast milk feeding require a public health perspective.     

Breastfeeding duration,age of starting solids and high BMI risk and adiposity in Indian children

This study utilized data from a prospective birth cohort study on 568 Indian children, to determine whether a longer duration of breastfeeding and later introduction of solid feeding were associated with a reduced higher body mass index (BMI) and less adiposity. Main outcomes were high BMI (>90th within‐cohort sex‐specific BMI percentile) and sum of skinfold thickness (triceps and subscapular) at age 5. Main exposures were breastfeeding (six categories from 1–4 to ≥21 months) and age of starting regular solid feeding (four categories from ≤3 to ≥6 months). Data on infant‐feeding practices, socio‐economic and maternal factors were collected by questionnaire. Birthweight, maternal and child anthropometry were measured. Multiple regression analysis that accounted for potential confounders demonstrated a small magnitude of effect for breastfeeding duration or introduction of solid feeds on the risk of high BMI but not for lower skinfold thickness. Breastfeeding duration was strongly negatively associated with weight gain (0–2 years) [adjusted β = –0.12 standard deviation, 95% confidence interval (CI): –0.19 to –0.05 per category change in breastfeeding duration, P = 0.001], and weight gain (0–2 years) was strongly associated with high BMI at 5 years (adjusted odds ratio = 3.8, 95% CI: 2.53–5.56, P < 0.001). In our sample, findings suggest that longer breastfeeding duration and later introduction of solids has a small reduction on later high BMI risk and a negligible effect on skinfold thickness. However, accounting for sampling variability, these findings cannot exclude the possibility of no effect at the population level.     

Breastfeeding practices of HIV-positive and HIV-negative women in Kabarole district, Uganda

Ugandan policy regarding infant feeding for HIV-positive mothers is replacement feeding (RF), if feasible; otherwise, exclusive breastfeeding (EBF) for 3 months is advised (or EBF for 6 months, if RF is still not feasible). HIV-negative mothers should practise EBF for 6 months. The study objective was to explore the association between maternal HIV status and breastfeeding practices in Kabarole, Uganda. Data were collected from questionnaires administered at home to 182 women (44 HIV-positive and 138 HIV-negative) 3 months post-partum and from medical charts. The HIV-negative women were matched on delivery date to HIV-positive women at a ratio of 3:1. Interviewers were blinded to HIV status. There was no statistically significant association between adherence to Ugandan national feeding guidelines and maternal HIV status in bivariate analysis [odds ratio (OR) = 1.52; confidence interval (CI): 0.76-3.04]. Multivariate analyses showed a significant association between adherence to feeding guidelines and child illness (OR = 0.40; CI: 0.21-0.79) and between adherence to feeding guidelines and rural residence in Burahya county (OR = 2.43; CI: 1.15-5.13). Many mothers do not follow the feeding guidelines for HIV infection. This region-specific information on breastfeeding practice determinants will be used to inform local Prevention of Mother-to-Child Transmission (PMTCT) programmes. The nature of the association between child illness and EBF should be further explored.     

Breastfeeding duration is associated with higher adiposity at 6–8 months of age

Breastfeeding (BF) has been identified as a protective factor against childhood obesity. However, evidence of the association between BF duration and adiposity remains inconclusive. Few studies have been conducted among Southeast Asian infants that have measured body composition during infancy using the gold standard stable isotope method. This study aimed to evaluate the association between BF duration and body composition during infancy. Healthy full‐term Thai infants aged 6–8 months (n = 60) receiving exclusive or predominant BF for at least 3 months were recruited. Skinfold thickness (SFT) was measured by well‐trained investigators. Body composition was assessed by the deuterium dilution technique. Infants with longer BF duration (>6 months; mean 7.5 ± 0.5 months, n = 29) had a higher subscapular SFT z‐score than those with shorter BF duration (≤6 months; mean 5.3± 0.9 months, n = 31) by 0.48 (95% confidence interval [CI]: 0.01–0.94). After adjustment for age and sex, BF duration and age at introduction of complementary feeding (CF) were positively associated with fat mass and fat mass index at 6–8 months. One month increase in BF duration and CF age was associated with a 0.37 (95% CI: 0.05, 0.69) kg/m² and 0.76 (95% CI: 0.18, 1.34) kg/m² increase in the fat mass index, respectively. After adjusting for infant body mass index (BMI) during the earlier infancy period, the strength of the association was attenuated. This finding may reflect reverse causality where infants with lower BMI received formula or CF earlier. A longitudinal study with follow‐up into childhood is warranted to confirm the effects of BF on adiposity in infancy and childhood.     

Transcutaneous bilirubinometry in very low birthweight infants

AIM: To evaluate whether transcutaneous bilirubinometry (TcB) would be a reliable and efficient screening technique for hyperbilirubinaemia in very low birthweight (VLBW, < or =1500 g) infants in an intensive care unit setting. METHODS: TcB measurements (Minolta Airshield Jaundice Meter JM-102, Osaka, Japan) were obtained immediately before or within 10 min following routine blood sampling for plasma bilirubin concentration measurements in 124 VLBW infants not receiving phototherapy. The relationship between the two techniques was analysed by linear regression analysis. A plasma bilirubin > or =150 micromol/l was defined as hyperbilirubinaemia. The sensitivity and specificity of possible TcB cut-off readings to detect hyperbilirubinaemia was evaluated. RESULTS: There was a significant correlation between the measurements of both techniques (p < 0.0001, r = 0.68). In the present study, a TcB cut-off reading of 14 would have reduced the need for plasma bilirubin measurements by 26% without missing true hyperbilirubinaemia. CONCLUSION: The data suggest that TcB will improve VLBW infant care in an intensive care unit setting by reducing the need for invasive bilirubin concentration measurements.     

Infant feeding practices among macrosomic infants: A prospective cohort study

The health benefits of breastfeeding are well recognised, but breastfeeding rates worldwide remain suboptimal. Breastfeeding outcomes have yet to be explored among women who give birth to macrosomic (birthweight ≥4000 g) infants, a cohort for whom the benefits of breastfeeding may be particularly valuable, offering protection against later‐life morbidity associated with macrosomia. This longitudinal prospective cohort study aimed to identify whether women who give birth to macrosomic infants are at greater risk of breastfeeding non‐initiation or exclusive breastfeeding (EBF) cessation. A total of 328 women in their third trimester were recruited from hospital and community settings and followed to 4 months post‐partum. Women gave birth to 104 macrosomic and 224 non‐macrosomic (<4000 g) infants between 2018 and 2020. Longitudinal logistic regression models calculated odds ratios (ORs) and 95% confidence intervals (CIs) to assess likelihood of EBF at four timepoints post‐partum (birth, 2 weeks, 8 weeks, and 4 months) between women who gave birth to macrosomic and non‐macrosomic infants, adjusted for maternal risk (obesity and/or diabetes), ethnicity and mode of birth. Macrosomic infants were more likely to be exclusively breastfed at birth and 2 weeks post‐partum than non‐macrosomic infants with adjusted OR = 1.94 (95% CI: 0.90, 4.18; p = 0.089) and 2.13 (95% CI: 1.11, 4.06; p = 0.022), respectively. There were no statistically significant associations between macrosomia and EBF at 8 weeks or 4 months post‐partum. Macrosomia may act as a protective factor against early formula‐milk supplementation, increasing the likelihood of EBF in the early post‐partum period, but rates of exclusive breastfeeding continued to decline over the first 4 months post‐partum.     

Breastfeeding Best Start study: training midwives in a 'hands off' positioning and attachment intervention

The most common reasons cited by women for giving up breastfeeding early can be attributed to ineffective positioning and attachment and are therefore preventable. This study aimed to determine whether a 4-h training programme in 'hands off' positioning and attachment support increases midwives' knowledge and problem-solving skills. Using an unrelated comparison group and a pre- and post-intervention design, 108 midwives (experimental group) completed a 4-h standard breastfeeding training workshop focusing on effective positioning and attachment and the use of hands-off teaching methods. Knowledge and problem-solving skills were assessed using a modified form of the previously validated Breastfeeding Support Skills Tool. Pre- and post-training scores were compared with those of 27 student midwives (control group) who undertook the same assessments but without the breastfeeding training. Baseline knowledge scores of the midwives and the student midwives did not differ significantly (average difference 0.7 points to qualified midwives' advantage, 95% CI = -3.4 to 1.9). Following training, the qualified midwives' total scores increased significantly (7.2 points, 95% CI = 6.2-8.2). Minimal changes (1.4 points, 95% CI = -0.15 to 2.9) in students' scores were found. The additional increase owing to training above that which might be expected due to practice (i.e. the average difference in change scores between the two groups) was 5.8 points (95% CI = 3.75-7.96), representing a large effect size for the training (d = 0.95). There is a large variation in the breastfeeding knowledge of midwives working in post-natal care and, on average, they are no more skilled than senior student midwives. The study has shown that a 4-h workshop in a positioning and attachment intervention, using a 'hands-off' approach, can increase midwives' knowledge of breastfeeding support relevant to the immediate post-natal period. It is applicable to all midwives, and could be a cost-effective way of improving the ability of mothers to begin and continue to breastfeed successfully.     

Choledocholithiasis in an infant of extremely low birthweight

A five-month-old infant of extremely low birthweight with choledocholithiasis is reported. A baby girl was delivered at 26 weeks gestation as a second twin, weighing 834 g. At 30 days of age, gallbladder stones were found by routine ultrasonography. She had vomiting at 157 days of age. Ultrasonography revealed calculi in the gallbladder and a dilated common bile duct. She was conservatively treated with scopolamine, antibiotics and dehydrocholic and ursodeoxycholic acids, and the calculi had disappeared by 189 days of age. Although conservative treatment succeeded in this patient, further cases should be analysed to establish how to manage choledocholithiasis in such small infants.     

Very low birthweight infants: outcome in a sub-Arctic population

Objective : To evaluate the outcome for very low birthweight (VLBW) infants in northern Norway. Subjects and methods: All live born infants ( n = 536) with birthweight ≤1500g born during 1978–89 to women residing in the northern health region of Norway were studied retrospectively. Data were from the Medical Birth Registry (MBR), hospital records and from follow-up recordings to 4 y of age at maternal and child health centres. Stillborn infants ( n = 269) with birthweight ≤1500g during the same period were also registered. Results : The annual incidence of live born VLBW infants (7.1/1000 live births) did not change, but the proportion of infants born alive before 26 weeks'gestation increased and the stillborn part decreased significantly. The Caesarean section (CS) rate, antenatal transfer and the use of a neonatal transport team increased significantly. Four hundred and seventy-five infants (89%) were considered viable at birth, 347 (65%) survived to 1 y and 343 (64%) to 4y. The likelihood of survival was independently related to female gender. The trend for survival to 4y of age did not increase significantly. Thirty children suffered from cerebral palsy (8.7% of survivors, 5.6% of live births) and the cerebral palsy rate for infants with birthweight 751-1000 g decreased. The proportion of survivors considered to be normal or mild disabled increased and the part suffering from moderate or severe disability decreased significantly. Conclusions : In spite of long distances and unfavourable climatic conditions VLBW infants can be adequately cared for in this sparsely populated region of Norway.     

Neonatal resuscitation of extremely low birthweight infants: a survey of practice in Italy

Delivery room management of extremely low birthweight infants (ELBWIs) has been little studied. A questionnaire was sent to the heads of the 86 Italian neonatal intensive care units provided with on site delivery. The practice of and approach to the resuscitation of ELBWIs were very different among the centres surveyed, reflecting a paucity of evidence and consequent uncertainty among clinicians.     

The very low birthweight infant: impact on parents during the pre-school years.

This paper presents follow-up data on 75 families who had children born between 1970 and 1971 at birthweights under 1501 g (very low birthweight: VLBW) and a comparison group of 55 families who had children born at the same time but at birthweights over 2500 g. An interview done when the children were 3--5 yr old revealed that parents with a VLBW child gave a less favourable evaluation of their child in 2 of 7 areas considered: development and play. These differences of evaluation were caused by a subgroup of 22 VLBW children with neurological and/or intellectual defects. No evidence came forth to indicate that the experience of having a VLBW child had significant or continuing impact on the family. An absence of serious social problems such as child abuse or the child's failure to thrive were noted.     

Erythromycin improves gastrointestinal motility in extremely low birthweight infants

Erythromycin (EM) was administered to five extremely low birthweight infants (ELBWI) with delayed enteral feeding to evaluate the clinical effect on severely impaired gastrointestinal motility. Five patients studied responded well to EM administration without any adverse effects during the course. Four patients were given 15–30 mg/kg per day EM intravenously as a loading and thereafter 3–5 mg/kg per day as a maintenance dose. One patient responded well without loading. The infants could be fed enterally 4, 5, 6, 4 and 2 days after the initiation of EM administration, respectively. Erythromycin administration is a safe and useful way to facilitate gastrointestinal motility in ELBWI who require prolonged ventilator support with an increased risk for nutrient deprivation.     

Breastfeeding and complementary feeding practices in rural Malawi

To facilitate optimal growth of newborns, many countries have developed infant feeding recommendations, usually suggesting 4-6 mo of exclusive breastfeeding and then the gradual introduction of complementary foods. We prospectively studied the changes in infant diets and predictors of adherence to national infant feeding recommendations in a cohort of 720 newborn babies in rural Malawi, Sub-Saharan Africa. Monthly interviews of the main guardians indicated that breastfeeding was universal for 18 mo. As most babies were given water or other supplemental foods soon after birth, the exclusive breastfeeding rates were only 19%, 8%, 2% and 0% at ages 1, 2, 3 and 4 mo, respectively. Complementary foods and family foods were introduced at median ages of 2.5 and 6.3 mo, i.e. much earlier than recommended. Better adherence to recommendations was associated with smaller number of children in the family, increased maternal education and some other socio-economic or environmental variables. CONCLUSION: Exclusive breastfeeding is uncommon and complementary foods were introduced early to newborns among these rural families. Education and family planning may improve adherence to infant feeding recommendations and reduce the incidence of early childhood malnutrition in Malawi.     

Breastfeeding and infant hospitalisation: analysis of the UK 2010 Infant Feeding Survey

To investigate the contributions of overall breastfeeding duration and exclusive breastfeeding in reducing the risk of hospitalisation for infectious causes, we analysed data from a three‐stage survey on infant feeding practices and health outcomes in over 10 000 UK women in 2010–2011. The main outcome measures were risk of overnight hospital admission in the first 8–10 months of infancy. A graded beneficial effect was found between longer duration of any breastfeeding and hospital admission for infectious causes and for respiratory tract infections, with a significantly lower risk in infants breastfed for at least 3 months compared with those never breastfed. The effects were stronger in the subgroup who was also exclusively breastfed. For example, among infants breastfed for 3–6 months, the reduction in risk for infectious causes for those who were also exclusively breastfed for at least 6 weeks was 0.42 (95% CI: 0.22–0.81) and for those not exclusively breastfed for 6 weeks 0.79 (95% CI: 0.49–1.26). Likewise, among infants breastfed for 6 months or more, the odds ratio for those who were also exclusively breastfed for at least 6 weeks was 0.48 (95% CI: 0.32–0.72) and for those not exclusively breastfed for 6 weeks 0.72 (95% CI: 0.48–1.08). The apparent protective effect of any breastfeeding for a long duration may in part be driven by a prolonged period of exclusive breastfeeding. Exclusive breastfeeding in the initial weeks after childbirth and continuing to breastfeed (either exclusively or partially) for at least 3 months, preferably 6 months, may reduce morbidity due to infectious illness in infants.     

Inguinal hernia in very low birthweight children: A continuing risk to age 8 years

The prevalence of inguinal hernia repair up to 8 years of age was determined in 205 inborn children of birthweight less than 1500 g who had survived to the age of 8 years; 37 (18.0%) of the children required surgery for inguinal hernia, significantly more frequently for boys than girls (32.0% and 3.9% respectively). The cumulative percentage of inguinal hernia operations in boys was 8.7% during primary hospitalization, 20.4% by 2 years, 30.1% by 5 years and 32.0% by 8 years; 36.4% (12 of 33) hernias in boys occurred beyond 2 years of age. The risk of hernia in boys was only marginally higher in those who required assisted ventilation and in those of birthweight less than 1000 g. Very low birthweight infants, particularly boys, are at risk of developing an inguinal hernia not only in infancy but also to at least 8 years of age.     

Coffin-Siris syndrome: A case of an extremely low birthweight infant with severe kyphoscoliosis

A case of Coffin-Siris syndrome in a male of extremely low birthweight with severe kyphoscoliosis is reported. His birthweight was 965 g, the lowest reported in the world for an infant with this syndrome. Coffin-Siris syndrome is characterized by nail hypoplasia of the fingers and toes, eyebrow hypertrichosis, prominent lips and prenatal or postnatal growth retardation. He was the only case who was mechanically ventilated from birth because of birth asphyxia. He died at 12 days of age because of sepsis, a poor immune system as in other extremely low birthweight infants, and because he easily suffered from upper respiratory infection as a result of Coffin-Siris syndrome. Kyphoscoliosis is suggested as one of the important features in low birthweight cases of Coffin-Siris syndrome in previous reports and in the present case.     

Meconium passage in extremely low birthweight infants and its relation to very early enteral nutrition

The aim of this study was to evaluate the correlation between the timing of the first and last meconium and feeding tolerance in the very early enteral nutrition of extremely low birthweight (ELBW) infants. Forty-one ELBW infants were fed following a standardized protocol (day 3-14). At 48 h of age bolus gavage feeding with milk was started (12 ml kg(-1) d(-1) increments, 12 meals per day). Gastric residuals up to 2 ml or up to 3 ml were tolerated in infants with a birthweight of < or = 750 g or > 750 g, respectively. No enemas or laxatives were given during the study. The impact of the time until the passage of the first (M-1) and last (M-last) meconium on the feeding volume on day 14 (V14) was evaluated by linear regression analysis. Data are presented as median (range). M-1 was 31 h (0.5-77 h), M-last was 6 d (1.4-22 d) and V14 was 99 (0-156) ml kg(-1). V14 increased with decreasing M-last (p < 0.001) but there was no correlation between V14 and M-1. V14 was 112 (0-156) ml kg(-1) if M-last was shorter than 6 d and 37 (0-147) ml kg(-1) if M-last was longer than 6 d. Conclusion: Rapid meconium evacuation appeared to be a key factor for the feeding tolerance of ELBW infants during the first 14 d of life. Further studies needed to investigate whether meconium passage can be accelerated and whether acceleration of the meconium passage will improve the early feeding tolerance in ELBWW infants.     

Breastfeeding patterns in exclusively breastfed infants: a longitudinal prospective study in Uppsala, Sweden

Exclusive breastfeeding was studied among 506 infants in Uppsala, Sweden, based on daily recordings during the first 6 mo. The mothers had previously breastfed at least one infant for at least 4 mo. Most of the mothers considered that they breastfed on demand. Wide variations in breastfeeding frequency and suckling duration were found both between different infants and in the individual infant over time. At 2 wk, the mean frequency of daytime feeds (based on one 13-d record) between different infants ranged from 2.9 to 10.8 and night-time feeds from 1.0 to 5.1. The daytime suckling duration (based on one 24-h record) ranged from 20 min to 4h 35 min and night-time duration from 0 to 2h 8 min. At any given age, a maximum of only 2% of the infants were not breastfed during the night. At 4 mo, 95% of the infants were breastfeeding and 40% were exclusively breastfed at this age. Longer breastfeeding duration and longer duration of exclusive breastfeeding were both associated with higher frequency of breastfeeds, longer breastfeeding of the previous child and higher education. No gender differences were found. Maternal smoking was associated with shorter duration of exclusive breastfeeding, and pacifier use was associated with shorter duration of both exclusive breastfeeding and total breastfeeding. This study confirms that every mother-infant pair needs to be understood as a unique dyad throughout lactation. These data demonstrate a wide range of patterns among women who are exclusively breastfeeding and indicate that it would be inappropriate to put pressure on individual families to adopt preconceived patterns of infant feeding.
