Association of Breastfeeding and the Federal Poverty Level: National Survey of Family Growth, 2011-2013

Association between sociodemographic characteristics and age stopped breastfeeding on early childhood weight status

INTRODUCTION

Epidemiological studies have suggested that breastfeeding is associated with child weight status. However, the length of breastfeeding in relation to child weight remains poorly understood. Therefore, this study investigated the association between age stopped breastfeeding and child weight status by sociodemographic characteristics.

METHODS

This cross-sectional analysis utilized a nationally representative sample of 3248 U.S. children ages 2-6 years from 2009 to 2018, from parents interviewed as part of the National Health and Nutrition Examination Survey. Child body weight and height were measured during physical examination. Information on age stopped breastfeeding and other demographic characteristics were assessed using questionnaires. Multivariable logistic regression models were performed to examine the association between age stopped breastfeeding and child weight status, adjusting for potential confounders.

RESULTS

Children breastfed for ≤ 11 months had an increased odds of being overweight and obese with the strongest association observed among those classified as obese (OR=2.12; 95%CI 1.23, 3.64) compared with children breastfed for > 11-24 months. The association between breastfeeding and child weight status was observed by racial/ethnic groups. Non-Hispanic white and Black children breastfed for ≤ 11 months had an associated increased likelihood of being overweight than their counterparts breastfed for > 11-24 months. Among Hispanic children, we observed elevated odds of being obese when breastfed for ≤ 11 months (OR=1.98; 95%CI 1.00, 3.91) than those breastfed for > 11-24 months.

CONCLUSION

Child weight status was associated with age stopped breastfeeding, where likelihood of being overweight and obese were greatest among children breastfed for ≤ 11 months.

Differences in Breastfeeding Among Medicaid and Commercially Insured Patients: A Retrospective Cohort Study

BACKGROUND

While breastfeeding rates have been increasing in the United States, they remain below targets set by multiple public health organizations. Lower rates are associated with certain demographic groups. We performed a retrospective chart review to examine rates of breastfeeding at the time of postpartum follow-up in a mixed-race urban cohort.

OBJECTIVE

This study was conducted to examine the proportion of women who were breastfeeding at 6-8 weeks postpartum and to determine if these proportions differed by race and insurance status.

MATERIALS AND METHODS

We identified women who delivered singleton term infants at an urban university hospital between July and December 2013. Self-reported breastfeeding status at 6-8 weeks postpartum was abstracted for all women who completed postpartum follow-up visits. Data were analyzed with logistic regression to compare rates of any or exclusive breastfeeding between women with Medicaid and private insurance.

RESULTS

Charts of 656 women were reviewed; 405 women completed postpartum follow-up within 8 weeks. The Medicaid population had significantly lower rates of breastfeeding even after accounting for interaction and confounding by demographic factors (any breastfeeding odd ratio [OR] 0.53, confidence interval [CI] 0.04-0.31; exclusive breastfeeding OR 0.48, CI 0.33-0.85). When stratified by race, white women on Medicaid had the lowest probability of breastfeeding of all groups (p < 0.01).

CONCLUSIONS

Among patients delivering at an urban academic hospital, women on Medicaid were significantly less likely to breastfeed than those with private insurance. The greatest differential by insurance was seen among white women. Efforts to improve breastfeeding should focus on low-income women of all races.

Cognitive Testing of the Brief Breastfeeding and Milk Expression Recall Survey

BACKGROUND

Major U.S. federal maternal and child health surveys collect an infant feeding history for children under 6 years of age using survey questions that have changed little over decades. Yet, infant feeding and lactation practices have changed with the increasing popularity of milk expression (pumping).

SUBJECTS AND METHODS

Cognitive interviews were conducted to test the 9-item Brief Breastfeeding and Milk Expression Recall Survey (BaByMERS) with a diverse sample of 15 U.S. mothers of children 1-5 years of age. A 42-item coding scheme was applied to identify interviewer and respondent problems in fielding and answering the questions. Problems were examined in relation to demographics and infant feeding and lactation history.

RESULTS

The extent of problems was modest. Of 42 possible problem codes, only 9 were identified as actual problems for one or more respondents on one or more questions. The most common problems involved uncertainty about the timing of when one started expressing milk, making a mental shift to realize that maternal milk expression and the child's consumption of that milk could be distinct concepts, and difficulty with certain terms or phrases. Problems tended to arise among mothers with more complex infant feeding or lactation histories, who also tended to be those with higher levels of education.

CONCLUSIONS

BaByMERS is a promising, brief tool for collecting a recalled infant feeding or lactation history among mothers with young children. Future research can evaluate additional characteristics of the tool to further confirm its utility for large epidemiological studies of maternal and child health.
