Preterm Birth, Pacifier use and Breastfeeding: is there a Relationship?

Correlation between Pacifier Use in Preterm Neonates and Breastfeeding in Infancy: A Systematic Review

Background: Breastfeeding is very important for the proper nutrition and growth of the child, as well as, the health of the mother. To start breastfeeding, the neonate must have extensive oral capacities for sucking functions but, premature neonates may not have the muscle strength needed to suck successfully. However, the non-nutritive sucking achieved by using a pacifier, has been identified by previous research as a factor associated with shorter duration and exclusivity of breastfeeding. This study aims to perform a systematic review to investigate the relationship between pacifier use in preterm neonates and breastfeeding in infancy. Methods: We included prospective studies, as well as randomized controlled studies that evaluated the association between pacifier use by preterm neonates and of breastfeeding in infancy. Ten research articles from PubMed/Medline, Google Scholar and Crossref were included in the review from a total of 1455 articles. The results differ depending on the type of study.Most prospective studies have shown a negative correlation between pacifier use and breastfeeding, while the randomized controlled studies found a positive correlation. Conclusions: Pacifier use in preterm infants helps transition from tube to oral feeding, breastfeeding, faster weight gain and earlier discharge from the NICU. However, the relationship between pacifiers and breastfeeding is more complicated, as it appears to be influenced by additional risk factors.

Factors associated with non-nutritive sucking habits at 2 years of age among very preterm children: EPIPAGE-2 cohort study

BACKGROUND

The association between prolonged non-nutritive sucking habits (NNSHs, ie, sucking pacifiers or fingers) and maxillofacial growth anomalies in the general population has been widely described. Because maturation of sucking abilities is not fully achieved in very preterm infants (<32 weeks' gestation), neonatal services worldwide rely on the use of pacifiers to promote the development of adequate sucking reflexes, possibly prolonging NNSHs during infancy.

OBJECTIVE

We aimed to describe the frequency and to identify factors associated with NNSHs at age 2 years in very preterm children.

METHODS

The study was based on data from EPIPAGE-2, a French national prospective cohort study of preterm births during 2011 that included 2593 children born between 24 and 31 weeks' gestation. The primary outcome was NNSHs at 2 years. Multivariable log-linear regression models with generalized estimation equations were used to study the association between the characteristics studied and NNSHs. Multiple imputations were used to take into account missing data.

RESULTS

The frequency of NNSHs was 69% in the overall sample but higher among girls (adjusted risk ratio [RR] 1.12, 95% confidence interval [CI] 1.05, 1.17), children born from multiple pregnancies (eg, twins/triplets) (RR 1.07, 95% CI 1.00, 1.11), children who were fed by nasogastric tube (RR 1.07, 95% CI 1.01, 1.13), or those who benefitted from developmental care programmes (RR 1.10, 95% CI 1.02, 1.19). The NNSHs frequency was lower if mothers were not born in France (RR 0.70, 95% CI 0.64, 0.77), children had 2 or more older siblings (RR 0.88, 95% CI 0.82, 0.96), or children were breast-fed at discharge (RR 0.90, 95% CI 0.85, 0.95).

CONCLUSIONS

NNSHs at 2 years seemed associated with cultural background, development care programmes, and breast feeding. Whether NNSHs at 2 years among very preterm children are associated with future maxillofacial growth anomalies deserves further attention.

Breastfeeding in the First Hours of Life Protects Against Pacifier Use: A Birth Cohort Study

Objective: To investigate risk factors for pacifier use in the first year of life. Materials and Methods: A prospective cohort study was conducted with children enrolled at birth in Porto Alegre, Southern Brazil, whose mothers underwent prenatal care at primary care units. Soon after the birth of the children, data were collected on anthropometrics, type of childbirth, and time until breastfeeding on the first day of life. At 6 and 12 months of age, data were collected on breastfeeding practices and whether the child had used a pacifier in the previous 6 months. Statistical analysis involved the use of Poisson regression with robust variance. Results: The incidence of pacifier use in the first year of life was 60% (317/532). The multivariable analysis showed that pacifier use in the first year of life was 33% higher when the mother was younger than 18 years of age (relative risk [RR] = 1.33; confidence interval [95% CI]: 1.01-1.76). Infants who breastfed in the first 30 minutes after birth had a 25% lower risk of pacifier use in the first year of life (RR = 0.75; 95% CI: 0.60-0.94), and those who breastfed between 30 minutes and 6 hours after birth had an 18% lower risk (RR = 0.82; 95% CI: 0.69-0.97) compared to those who took longer to begin breastfeeding or did not breastfeed. Conclusions for Practice: Breastfeeding soon after being born protected against pacifier use in the first year of life. This finding suggests pathways to improve child health, especially in the prenatal period and with an emphasis on pregnant adolescents.

Breastfeeding as an analgesic method during vaccinations

INTRODUCTION

Infants undergo painful stings such as intradermal and intramuscular stings during vaccination. Clinical trial have showed analgesic methods to reduce the painful in both infants and kids.

EVIDENCE ACQUISITION

There are different types of non-pharmacological interventions which have an analgesic effect in infants during vaccinations such as: breastfeeding, cladding the infants, the skin to skin contact, the use of sweetened substance.

EVIDENCE SYNTHESIS

A review of the primary and secondary literature was carried out in the database Medline(PubMed). The bibliographic research was focused on the critical reading of the studies of the last ten years. Eight articles, including seven randomized clinical trials and one systematic review have been found. All registered studies report a reduction of the average value of the pain measured through both validated rating scales and through the measurement of the average duration of the cry during and after the vaccination in breastfeed infants. However it hasn't been demonstrated a statistically significant improvement in physiological parameters.

CONCLUSIONS

It is desirable that the literature produce further studies related to the changes of the vital parameters during the breastfeeding which allow a clear comparison between clinical trials.

Risk factors for communication disorders and complaints of preschoolers in a School Health Program

ABSTRACT Purpose: to survey the prevalence of risk factors for communication disorders and complaints in preschoolers that participated in the School Health Program (SHP) and compare the findings with age and sex. Methods: the sample comprised 190 preschoolers reached by the SHP. The collection procedure involved the exploration of data in questionnaires previously filled out by their relatives. The risk factors and communication complaints were presented in the occurrence frequency. The evidence of associations between variables was verified with the Mann-Whitney and chi-square tests, and the 5% significance level was used for all comparisons. Results: baby bottle use was the most prevalent risk factor associated with age, being more frequent in younger children. The girls underwent more complications during pregnancy or birth and showed more nonnutritive sucking habits, whereas the boys had more hospital stays. Conclusion: regarding the investigated risk factors, the baby bottle use was the most reported one, followed by ear infections or other ear problems. Complaints related to speaking and hearing were seldom mentioned, although those related to speaking occurred more frequently.
