Breastfeeding Duration and Exclusivity Among Early-Term and Full-Term Infants: A Cohort Study.

ABSTRACT:

Background

As compared to full-term infants (39-41 weeks of gestation), early-term infants (37-38 wk) are at increased risk of adverse outcomes, including shorter exclusive breastfeeding (EB) duration and continued breastfeeding.

Objectives

To compare early-term with full- and late-term infants regarding the prevalence of EB at 3 mo and any breastfeeding at 12 mo.

Methods

Data sets from two population-based birth cohorts conducted in the city of Pelotas, Brazil, were combined. Only term infants (37 0/7 through 41 6/7 weeks of gestation) were included in the analyses. Early-term infants (37 0/7 through 38 6/7 wk) were compared to the remaining term infants (39 0/7 through 41 6/7 wk). Information on breastfeeding was gathered through maternal interviews at the 3-mo and 12-mo follow-ups. The prevalence of EB at 3 mo and any breastfeeding at 12 mo with 95% CIs were calculated. Crude and adjusted prevalence ratios (PRs) were obtained through Poisson regression.

Results

A total of 6395 infants with information on gestational age and EB at 3 mo and 6401 infants with information on gestational age and any breastfeeding at 12 mo were analyzed. There was no difference between early-term infants and the remaining term infants regarding the prevalence of EB at 3 mo (29.2% and 27.9%, respectively) (P = 0.248). Prevalence of any breastfeeding at 12 mo was lower in early-term infants than among those born between 39 0/7 and 41 6/7 weeks of gestation (38.2% compared with 42.4%) (P = 0.001). In the adjusted analysis, the PR for any breastfeeding at 12 mo was 15% lower in the early-term group than in the remaining term infants (PR = 0.85; 95% CI: 0.76-0.95) (P = 0.004).

Conclusions

The prevalence of EB at 3 mo was similar among term infants. Nonetheless, in comparison with the remaining infants born at term, early-term infants were at increased risk of having been weaned before reaching 12 mo of age. Curr Dev Nutr 2023;xx:xx.

Project description:BackgroundPregnant participants who perceived that the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) recommends breastfeeding only were more likely to have better early breastfeeding outcomes.ObjectivesOur objective was to examine the association between prenatal perception of WIC's breastfeeding recommendations and breastfeeding duration through the first year of infant life.MethodsThis observational study used a national longitudinal sample of 1594 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 in 2013. Four measures of breastfeeding duration were used: 1) a discrete measure of exclusive breastfeeding through 5 mo; 2) a continuous measure of exclusive breastfeeding (in days up to 7 mo); 3) a discrete measure of any breastfeeding through 11 mo; and 4) a continuous measure of any breastfeeding (in days up to 13 mo). The primary explanatory variable was the participant's prenatal perception of whether WIC recommended breastfeeding only. The univariate analyses of time to breastfeeding cessation were performed using Kaplan-Meier curves. The Cox regression model was adopted to estimate the likelihood of breastfeeding outcomes over time. All analyses accounted for complex survey design effects.ResultsCompared with their peers who perceived WIC to recommend formula only or both breastfeeding and formula equally, participants who perceived WIC as recommending breastfeeding only were less likely to stop exclusive breastfeeding through 5 mo (HR = 0.83; 95% CI: 0.69, 0.99) or to stop any breastfeeding through 11 mo (HR = 0.80; 95% CI: 0.69, 0.92), without controlling for prenatal infant feeding intentions. Similar patterns were observed in the 2 continuous measures, as they were also less likely to stop exclusive breastfeeding by 7 mo (HR = 0.78; 95% CI: 0.69, 0.90) or to stop any breastfeeding by 13 mo (HR = 0.82; 95% CI: 0.71, 0.95).ConclusionsPrenatal perception of WIC's breastfeeding recommendation can be a useful predictor of breastfeeding duration in WIC participants.

Project description:BackgroundBreastfeeding has important positive long-term health consequences for infants and mothers. The World Health Organization recommends that all infants should be exclusively breastfed for six months or longer, and advises continuation of breastfeeding for two years or beyond. However, these recommendations are not met in many countries. This study examined whether a comprehensive, evidence-based breastfeeding intervention, the Breastfeeding Support Programme (BSP), promotes prolonged duration and exclusivity of breastfeeding among its participants.MethodsA quasi-experimental design was used to compare breastfeeding duration and exclusivity in the BSP group (N = 66) to breastfeeding duration and exclusivity in a control group (N = 72). Participants who followed the BSP were provided with 6 consults delivered by a lactation consultant. The consults started during pregnancy and continued up until 10 weeks after delivery. Participants in the control group did not follow the BSP. Pretest and posttest questionnaires were administered through the internet. A Cox proportional hazards regression analysis was used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for cessation of any and exclusive breastfeeding, while controlling for differences at baseline.ResultsThe effect of the BSP on survival rates for any and exclusive breastfeeding were significant while controlling for differences between the two groups at baseline (respectively HR = 0.34, p < .001 [95% CI = 0.18-0.61] and HR = 0.46, p < .001 [95% CI = 0.29-0.72]). Among mothers in the BSP group there was on average 66% less risk of cessation of any breastfeeding and on average 54% less risk of cessation of exclusive breastfeeding at any point in time compared to those in the control group.ConclusionsThe BSP appears to be an effective means to delay cessation of any and exclusive breastfeeding cessation and therefore to increase breastfeeding duration and exclusivity. This is an important finding, because earlier cessation of breastfeeding than desired is a common problem in many countries. Future research into the effectiveness of the BSP could consider random assignment to conditions and test the effectiveness of the intervention in other populations to investigate further whether wide-scale implementation of this intervention could be useful to promote breastfeeding.

Project description:BackgroundThe association between gestational weight gain and neonatal body composition has been inconsistent, exposing the need for further research. The aim of this study was to evaluate whether gestational weight gain influences the body composition of full-term newborns and infants up to 4 months old.MethodsA cohort study was performed with 124 participants divided into categories of gestational weight gain according to the 2009 Institute of Medicine guidelines. The anthropometric and body composition data of newborns and infants acquired using air displacement plethysmography (PeaPod®) were collected at 96 h, 1 month, 2 months and 4 months of life. In the statistical analysis, the chi-square test was used to analyze categorical variables, and ANOVA was used to analyze numerical variables. Univariate analysis was performed, and the absolute and relative frequencies of the categorical variables, as well as mean and standard deviation of the numerical variables, were obtained. Bivariate analysis was performed for the categories of gestational weight gain and gestational and neonatal characteristics. When adjustments to gestational hypertension, gestational diabetes, and pregestational body mass index (BMI) were analyzed by linear regression, gestational weight gain remained a significant variable for newborn percent fat mass. For all analyses, a significance level of 5% was adopted.ResultsGestational weight gain was adequate in 33.8% of the participants, excessive in 41.1% and insufficient in 25%. Women with excessive weight gain had higher pregestational BMIs and a higher incidence of gestational hypertension. Their newborns had a higher body mass, body fat mass in grams and percent fat mass than the infants born to mothers with adequate or insufficient gestational weight gain. No significant differences were observed in body composition at 1, 2 and 4 months of life during infant follow-up.ConclusionExcessive gestational weight gain may alter the body composition of newborns at birth. Further studies are required to better evaluate infant follow-up.Trial registrationClinical Trial Registry: NCT00875251 on April 3, 2009.

Project description:The multifactorial aspects of breastfeeding require measures at many levels to identify mothers in need of breastfeeding support from healthcare professionals. Our objective was to examine the relative importance of sociodemographic, pre/perinatal-, infant-, psychosocial-, and interaction-related factors affecting duration of exclusive breastfeeding. We used self-reported data from a community-based trial including 1265 women (response rate 49%) giving birth from January 2017 to February 2018. Data on outcome, duration of exclusive breastfeeding, were collected three and nine months postpartum; data on the study variables concerning known risk factors for breastfeeding cessation were collected two weeks postpartum. Crude and multiple Cox proportional hazards models were used for statistical analyses with additional analyses for time varying effects. Factors with an independent prognostic influence on duration of exclusive breastfeeding in fully adjusted models included early skin-to-skin contact (HR = 1.18 CI:1.04-1.33), intention to breastfeed (HR = 0.77 CI: 0.73-0.80), positive outcome evaluation, meaning the value mothers attributed to breastfeeding (HR = 1.33 CI: 1.08-1.63), higher level of self-efficacy (HR = 1.46 CI: 1.24-1.72), and maternal sense of security in relation to breastfeeding (HR = 1.31 CI: 1.14-1.50). Higher maternal BMI, lower self-efficacy, shorter breastfeeding duration of previous child, and hospitalization during birth were time dependent by affecting the exclusive breastfeeding duration primarily in the first months following birth. The results suggest that target groups in special need of early breastfeeding support are defined by being hospitalized, obese, having low self-efficacy or short previous breastfeeding experience. The extensive influence of psychosocial factors emphasizes the importance of including both practical facilitating guidance and positive verbal encouragement to ensure effective breastfeeding support.
