Prepregnancy Weight, Weight Gain during Pregnancy, and Exclusive Breastfeeding in the First Month of Life in Rio de Janeiro, Brazil

Abstract

To examine the relationship between maternal prepregnancy weight, gestational weight gain and early introduction of non-breast milk foods and fluids (EINB) in the first month of life, we investigated 592 adult women and their newborns, admitted at health care units in Rio de Janeiro, Brazil. EINB was defined as the introduction of water, tea, juice, other types of milk or food during the first month postpartum. Logistic regression models were used for the analyses. Prepregnant obese women had increased odds of EINB as compared to those with normal weight (odds ratio [OR] = 2.14, 95% confidence interval [CI] = 1.23-3.71). Overweight and obese women who exceeded the recommended gestational weight gain had significantly greater odds of EINB (OR = 2.29, 95% CI = 1.16-4.51, and OR = 3.33, 95% CI = 1.49-7.47, respectively), compared with those with normal weight and adequate gestational weight gain. These findings highlight the importance of providing overweight/obese women with proper lactation guidance in the early postpartum to support for exclusive breastfeeding practices.

Longer breastfeeding duration reduces the positive relationships among gestational weight gain, birth weight and childhood anthropometrics

“…Yet, it is not well known whether early life nutrition mediates the pathway from GWG to childhood growth. Since infant feeding practices are associated with maternal GWG as well as childhood growth and obesity,2 16 investigation of the mediation effect of infant feeding practices is warranted and might identify modifiable early nutrition factors for obesity mitigation strategies. Furthermore, despite numerous studies on GWG and childhood obesity, limited data are available on GWG and linear growth.…”

Breastfeeding Education and Support Trial for Overweight and Obese Women: A Randomized Trial

“…The etiology of these breastfeeding difficulties is likely multifactorial. [7][8][9][10][11][12][13] These suboptimal breastfeeding practices are concerning, because children of obese women are at high risk of developing obesity 14 and a growing body of evidence indicates that breastfeeding is protective against childhood obesity. [15][16][17][18] Given the high rates of overweight and obesity among US low-income women, 19 combined with their poor breastfeeding practices, 20 it is essential to evaluate interventions promoting breastfeeding to overweight/obese, low-income women.…”

Predictive Models for Characterizing Disparities in Exclusive Breastfeeding Performance in a Multi-ethnic Population in the US

“…Thus, random errors due to retrospective recall may exist, which may partly contribute to the wide confidence intervals for effect estimates. However, such self-reported data have been used successfully previously [51,52] and have shown to provide valid and reliable estimates of breastfeeding duration with recall lengths varying from 3 years after the practice to 20 years after delivery [53,54]. Second, some factors which may influence mother's choice of infant feeding practices are not available in this study, e.g.…”
