WIC Participation and Breastfeeding at 3 Months Postpartum

Objectives Participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has been associated with lower breastfeeding initiation and duration. This study examines breastfeeding-related factors among WIC participants and nonparticipants that might explain these previous findings. Methods Respondents to the 2007 Infant Feeding Practices Study II who were income-eligible for WIC were categorized as follows: no WIC participation (No-WIC); prenatal participation and infant entry while ≥60 % breastfeeding (WIC BF-high); prenatal participation and infant entry while <60 % breastfeeding (WIC BF-low). Percent breastfeeding was the number of breast milk feeds divided by the total number of liquid feeds. Using propensity scores, we matched WIC BF-high respondents to No-WIC respondents on demographic and breastfeeding factors. We used logistic regression to estimate the impact of WIC participation on breastfeeding at 3 months postpartum in the matched sample. Within-WIC differences were explored. Results Of 743 income-eligible respondents, 293 never enrolled in WIC, 230 were categorized as WIC BF-high, and 220 as WIC BF-low. Compared to matched No-WIC respondents, WIC BF-high respondents had increased odds of breastfeeding at 3 months, though this difference was not statistically significant (OR 1.92; 95 % CI 0.95–3.67; p value 0.07). WIC BF-high respondents were more similar on breastfeeding-related characteristics to No-WIC respondents than to WIC BF-low respondents. Conclusions for Practice Accounting for prenatal breastfeeding intentions and attitudes, we find no negative association between WIC participation and breastfeeding at 3 months postpartum. This is in contrast to prior studies, and highlights the importance of understanding within-WIC differences.     

American Indian Breastfeeding Attitudes and Practices in Minnesota

Objectives We examined the breastfeeding attitudes and practices in an American Indian population in Minnesota. Methods We interviewed women prenatally (n = 380), at 2-weeks (n = 342) and at 6-months postpartum (n = 256). We conducted multivariable analyses to examine the demographic, behavioral, and attitudinal correlates of breastfeeding initiation and duration. Results Factors positively associated with breastfeeding initiation included positive breastfeeding attitudes and social support for breastfeeding from the woman’s husband/boyfriend and her mother. Factors positively associated with breastfeeding at 2-weeks postpartum were support from the woman’s mother and positive attitudes about breastfeeding. The prenatal use of traditional American Indian medicines and cigarette smoking were both significantly associated with breastfeeding at 6-months postpartum. Conclusions Programs to encourage breastfeeding in American Indian communities may be strengthened with protocols to encourage social support, recognition of the perceived health, developmental, and practical benefits of breastfeeding, and a focus on traditional American Indian health practices.     

The Associations of Maternal Weight Change with Breastfeeding,Diet and Physical Activity During the Postpartum Period

Objective To determine the association between breastfeeding practices, diet and physical activity and maternal postpartum weight. Methods This was a secondary data analysis of a randomized community trial on beneficiaries of the Programa de Desarrollo Humano Oportunidades, recently renamed Prospera (n = 314 pregnant women), without any diseases that could affect body weight. Generalized estimating equations were used to determine the association between postpartum weight change and changes in diet, physical activity and type of breastfeeding. Results The mean postpartum weight change from the first to the third month was 0.6 ± 2.2 kg. Women who breastfed exclusively for 3 months had a 4.1 (SE = 1.9) kg weight reduction in comparison with women who did not provide exclusive breastfeeding or who discontinued breastfeeding before 3 months (p = 0.04). There was no association between postpartum weight change and physical activity (p = 0.24) or energy intake (p = 0.06). Conclusions Exclusive breastfeeding was associated with maternal postpartum weight reduction. These results reinforce the World Health Organization recommendation of exclusive breastfeeding during the first 6 months of life in order to reduce the risk of weight retention or weight gain in postpartum women. It has been well established that exclusive breastfeeding is beneficial for both infants and mothers, but promoting breastfeeding as a strategy to promote postpartum weight loss is of paramount importance, especially in countries like Mexico where excessive weight in women of reproductive age is a public health problem.     

Prenatal and Postnatal Fruit and Vegetable Intake Among US Women: Associations with WIC Participation

Objective Evaluate variation in fruit and vegetable intake by Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation and poverty status among pregnant, and postpartum women participating in the Infant Feeding Practice Study II (IFPSII). Methods IFPSII (2005–2007) followed US women from third trimester through 1 year postpartum through mailed questionnaires measuring income, WIC participation, breastfeeding; and dietary history questionnaires (DHQ) assessing prenatal/postnatal fruit and vegetable consumption. Poverty measurements used U.S. Census Bureau Federal Poverty thresholds to calculate percent of poverty index ratio (PIR) corresponding to WIC’s financial eligibility (≤185 % PIR). Comparison groups: WIC recipients; WIC eligible (≤185 % PIR), but non-recipients; and women not financially WIC eligible (>185 % PIR). IFPSII participants who completed at least one DHQ were included. Intake variation among WIC/poverty groups was assessed by Kruskal–Wallis tests and between groups by Mann–Whitney Wilcoxon tests and logistic regression. Mann–Whitney Wilcoxon tests examined postnatal intake by breastfeeding. Results Prenatal vegetable intake significantly varied by WIC/poverty groups (p = 0.04) with WIC recipients reporting significantly higher intake than women not financially WIC eligible (p = 0.02); association remained significant adjusting for confounders [odds ratio 0.66 (95 % confidence interval: 0.49–0.90)]. Prenatal fruit and postnatal consumption did not significantly differ by WIC/poverty groups. Postnatal intake was significantly higher among breastfeeding than non-breastfeeding women (fruit: p < 0.0001; vegetable: p = 0.006). Conclusions for Practice Most intakes did not significantly differ by WIC/poverty groups and thus prompts research on WIC recipient’s dietary behaviors, reasons for non-participation in WIC, and the influence of the recent changes to the WIC food package.     

Improved Outcomes for Hispanic Women with Gestational Diabetes Using the Centering Pregnancy<Superscript>©</Superscript> Group Prenatal Care Model

Objective To determine the impact of Centering Pregnancy^©-based group prenatal care for Hispanic gravid diabetics on pregnancy outcomes and postpartum follow-up care compared to those receiving traditional prenatal care. Methods A cohort study was performed including 460 women diagnosed with gestational diabetes mellitus (GDM) who received traditional or Centering Pregnancy^© prenatal care. The primary outcome measured was completion of postpartum glucose tolerance testing. Secondary outcomes included postpartum visit attendance, birth outcomes, breastfeeding, and initiation of a family planning method. Results 203 women received Centering Pregnancy^© group prenatal care and 257 received traditional individual prenatal care. Women receiving Centering Pregnancy^© prenatal care were more likely to complete postpartum glucose tolerance testing than those receiving traditional prenatal care, (83.6 vs. 60.7 %, respectively; p < 0.001), had a higher rate of breastfeeding initiation (91.0 vs. 69.4 %; p < 0.001), had higher rates of strictly breastfeeding at their postpartum visit (63.1 vs. 46.3 %; p = 0.04), were less likely to need medical drug therapy compared to traditional prenatal care (30.2 vs. 42.1 %; p = 0.009), and were less likely to undergo inductions of labor (34.5 vs. 46.2 %; p = 0.014). When only Hispanic women were compared, women in the Centering group continued to have higher rates of breastfeeding and completion of postpartum diabetes screening. Conclusion for Practice Hispanic women with GDM who participate in Centering Pregnancy^© group prenatal care may have improved outcomes.     

Postpartum Contraception and Interpregnancy Intervals Among Adolescent Mothers Accessing Public Services in California

Objective To determine the association of age at index birth with postpartum contraceptive use and optimal interpregnancy interval (IPI, defined as delivery to next pregnancy >18 months), controlling for provider type and client demographics among adolescent mothers who have repeat pregnancies. Methods California’s 2008 birth records were linked to California’s Medi-Cal and Family PACT claims data to identify 26,393 women with repeat births between 2002 and 2008, whose index birth occurred as an adolescent, and who received publicly-funded services within 18 months after the index birth. Multivariable regression analyses were conducted to examine the relationship between timing of contraception provision and interpregnancy intervals, adjusting for socio-demographic factors. Results Seventy-eight percent of adolescent women did not receive contraception at their first postpartum visit, and twenty-eight percent of adolescent women never received contraception from a Family PACT or Medi-Cal provider. Adolescents who were older at their index birth had lower rates of optimal IPIs. Native American, Asian-Pacific Islander and Latina women had lower rates of optimal IPIs compared to white women. Compared to those using only barrier methods, adolescent women receiving highly effective contraceptive methods had a 4.25 times higher odds of having an optimal IPI than those receiving hormonal methods (OR 2.10), or using no method (OR 0.70). Conclusion Effective postpartum contraceptive use and being a Family PACT provider were associated with optimal birth spacing among adolescent mothers, yet racial and ethnic disparities persisted. A missed opportunity was the provision of contraception at the first postpartum visit. Providers should aim to remove barriers to initiation of contraception at this visit.     

Use of maternal health services: comparing refugee,immigrant and US-born populations

Objectives To determine use of recommended maternal healthcare services among refugee and immigrant women in a setting of near-universal insurance coverage. Methods Refugee women age ≥18 years, who arrived in the US from 2001 to 2013 and received care at the same Massachusetts community health center, were matched by age, gender, and date of care initiation to Spanish-speaking immigrants and US-born controls. The primary outcome was initiation of obstetrical care within the first trimester (12 weeks gestation). Secondary outcomes were number of obstetrical visits and attending a postpartum visit. Results We included 375 women with 763 pregnancies (women/pregnancies: 53/116 refugee, 186/368 immigrant, 136/279 control). More refugees (20.6 %) and immigrants (15.0 %) had their first obstetric visit after 12 weeks gestation than controls (6.0 %, p < 0.001). In logistic regression models adjusted for age, education, insurance, BMI, and median census tract household income, both refugee (odds ratio [OR] 4.58, 95 % confidence interval [CI] 1.73–12.13) and immigrant (OR 2.21, 95 % CI 1.00–4.84) women had delayed prenatal care initiation. Refugees had fewer prenatal visits than controls (median 12 vs. 14, p < 0.001). Refugees (73.3 %) and immigrant (78.3 %) women were more likely to have postpartum care (controls 54.8 %, p < 0.001) with differences persisting after adjustment (refugee [OR 2.00, 95 % CI 1.04–3.83] and immigrant [OR 2.79, 95 % CI 1.72–4.53]). Conclusions for Practice Refugee and immigrant women had increased risk for delayed initiation of prenatal care, but greater use of postpartum visits. Targeted outreach may be needed to improve use of beneficial care.     

Tobacco Use and Cessation Among Pregnant Alaska Natives from Western Alaska Enrolled in the WIC Program, 2001–2002

Objectives This study examined the rate of tobacco use (cigarette smoking and smokeless tobacco [ST]) at three time points: during the 3 months before pregnancy, during pregnancy, and at 6 weeks postpartum among Alaska Native women residing in the Y-K Delta region of Western Alaska. Methods A retrospective, non-randomized observational cohort design was utilized. The sample consisted of 832 Alaska Natives (mean maternal age = 26.2 years, average length of gestation = 3.8 months) seen at their first prenatal visit and enrolled in the women, infant, and children (WIC) program at the Yukon-Kuskokwim Delta Regional Hospital in Bethel, Alaska, during a 2-year-period (2001–2002). Tobacco use was assessed using an interview format at the first prenatal and at the 6-week postpartum visits. Results The rates of any tobacco use were 48% (95% CI 45%, 52%) 3 months before pregnancy, 79% (95% CI 76%, 82%) during pregnancy, and 70% (95% CI 67%, 74%) at 6 weeks postpartum. The proportion of women using ST changed significantly (P < 0.001) over the three time points (14%, 60%, and 61%, respectively) as well as the proportion of women who smoked cigarettes (P < 0.001) (40%, 42%, and 19%, respectively). Conclusions This study documents the high rate of tobacco use, particularly ST use, during pregnancy among Alaska Native women. Development of tobacco use prevention and cessation interventions during pregnancy for Alaska Native women is warranted.     

Breastfeeding Outcomes in Washington State: Determining the Effect of Loving Support Peer Counseling Program and Characteristics of Participants at WIC Agencies

Objective

Determining the effect of the Loving Support Peer Counseling Program (LSPCP), and characteristics of participants on breastfeeding (BF) outcomes at Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) agencies in Washington State.

Maternal Nonstandard Work Schedules and Breastfeeding Behaviors

Objectives Although maternal employment rates have increased in the last decade in the UK, there is very little research investigating the linkages between maternal nonstandard work schedules (i.e., work schedules outside of the Monday through Friday, 9–5 schedule) and breastfeeding initiation and duration, especially given the wide literature citing the health advantages of breastfeeding for mothers and children. Methods This paper uses a population-based, UK cohort study, the Millennium Cohort Study (n?=?17,397), to investigate the association between types of maternal nonstandard work (evening, night, away from home overnight, and weekends) and breastfeeding behaviors. Results In unadjusted models, exposure to evening shifts was associated with greater odds of breastfeeding initiation (OR 1.71, CI 1.50–1.94) and greater odds of short (OR 1.55, CI 1.32–1.81), intermediate (OR 2.01, CI 1.64–2.47), prolonged partial duration (OR 2.20, CI 1.78–2.72), and prolonged exclusive duration (OR 1.53, CI 1.29–1.82), compared with mothers who were unemployed and those who work other types of nonstandard shifts. Socioeconomic advantage of mothers working evening schedules largely explained the higher odds of breastfeeding initiation and duration. Conclusions Socioeconomic characteristics explain more breastfeeding behaviors among mothers working evening shifts. Policy interventions to increase breastfeeding initiation and duration should consider the timing of maternal work schedules.     

When Fathers are Perceived to Share in the Maternal Decision to Breastfeed: Outcomes from the Infant Feeding Practices Study II

Objectives The present study investigates the influence of joint feeding preferences of both the mother and father on initiation and duration of breastfeeding. Methods Data from the Infant Feeding Practices Study II was analyzed. Female participants in a national consumer opinion panel were followed from pregnancy through 1 year postpartum, and were asked about infant feeding practices. We examined the association between maternal prenatal perception of the expectant father’s breastfeeding preferences and breastfeeding outcomes (initiation, duration of exclusive breastfeeding and any breastfeeding) and whether concordance between the parents’ infant feeding preferences influenced breastfeeding. Results Mothers who perceived that the father preferred exclusive breastfeeding (vs. no preference) were more likely to initiate breastfeeding [adjusted odds ratio (aOR)?=?1.9; 95% confidence interval (95% CI) 1.0–3.7], and they had a lower hazard of stopping exclusive and any breastfeeding at any given time [exclusive breastfeeding: adjusted hazard ratio (aHR)?=?0.8; 95% CI 0.6–0.9; any breastfeeding: aHR?=?0.6; 95% CI 0.5–0.7]. When both the mother and the father preferred exclusive breastfeeding, the hazard of breastfeeding cessation at any given time was lowest (exclusive breastfeeding: aHR?=?0.4; 95% CI 0.3–0.5; any breastfeeding: aHR?=?0.4; 95% CI 0.3–0.5). The risk of breastfeeding cessation remained lower even when only the father preferred exclusive breastfeeding. Conclusions for Practice Mothers tend to breastfeed for a longer duration when they perceive that the expectant father prefers exclusive breastfeeding and, even more so, when both parental preferences for exclusive breastfeeding concur. Efforts are needed to involve expectant fathers in breastfeeding decision-making and education to achieve breastfeeding success.     

Postpartum Depression and Anxiety Among Mothers Whose Child was Placed in Care of Child Protection Services at Birth: A Retrospective Cohort Study Using Linkable Administrative Data

Objectives This study examines whether mothers involved with child protection services (CPS) at the birth of their first child had higher rates of postpartum depression and anxiety. Methods A retrospective cohort of mothers whose first child was born in Manitoba, Canada between April 1, 1995 and March 31, 2015 is used. Postpartum depression and anxiety among mothers whose first child was placed in care at birth (n?=?776) was compared with mothers who received services from CPS (but whose children were not placed in care) (n?=?4,270), and a 3:1 matched group of mothers who had no involvement with CPS in the first year of their firstborn’s life (n?=?2,328). Adjusted odds ratios (AOR) of depression and anxiety diagnoses in the first year postpartum were obtained from logistic regression models. Adjusted rate ratios (ARR) of antidepressant use obtained using Poisson models. Results Mothers whose children were taken into care have greater odds of having a postpartum depression or anxiety diagnosis than mothers receiving services (AOR?=?1.31; 95% CI 1.08–1.59) and those not involved with CPS (AOR?=?2.13; 95% CI 1.67–2.73). Among mothers who had a postpartum depression or anxiety diagnosis, mothers whose children were placed in care had significantly higher rates of antidepressant use than mothers receiving services only (ARR?=?2.00; 1.82, 2.19) and mothers who were not involved with CPS (ARR?=?2.42; 95% CI 1.94–3.51). Conclusions for Practice Targeted programs should be implemented to address postpartum mental illness among mothers who are involved with CPS at the birth of their child.     

Comparing Weight-for-Length Status of Young Children in Two Infant Feeding Programs

Objectives A cross-sectional study comparing weight-for-length status of children 6–24 months old who participated in Nurse-Family Partnership (NFP) or Special Supplemental Program for Women, Infants, and Children (WIC). Methods Secondary analysis of NFP (n = 44,980) and WIC (n = 31,294) national datasets was conducted to evaluate infant and toddler growth trajectories. Weight-for-length status was calculated at 6, 12, 18, and 24 months based on World Health Organization criteria. Demographics and breastfeeding rates were also evaluated. Binary logistic regression was used to calculate odds ratios for high weight-for-length (≥97.7 percentile) at each time point. Results At 6 months, approximately 10 % of WIC and NFP children were classified as high weight-for-length. High weight-for-length rates increased for both groups similarly until 24 months. At 24 months, NFP children had significantly lower rates of excess weight (P = 0.03) than WIC children, 15.5 and 17.5 % respectively. At all time points, non-Hispanic white children had lower rates of high–weight for length than Hispanic and non-Hispanic black children. NFP infants were also found to have higher rates of ever being breastfed than WIC infants (P < 0.0001). Conclusions for Practice Infant and toddler populations served by NFP or WIC were found to be at increased risk for high weight-for-length. This study found NFP participation was associated with a small, but significant, protective impact on weight-for-length status at 24 months. Continued efforts need to be made in addressing weight-related racial/ethnic and socioeconomic disparities during early childhood.     

Breastfeeding and Exposure to Past,Current, and Neighborhood Violence

Objectives Breastfeeding has short- and long-term health benefits for children and mothers, but US breastfeeding rates are suboptimal. Exposure to violence may contribute to these low rates, which vary by race/ethnicity. We studied: (1) whether patterns of violence exposure differ by race/ethnicity and (2) whether these patterns are associated with breastfeeding outcomes. Methods We conducted a secondary analysis of data drawn from self-report surveys completed by a convenience sample of low-income postpartum women (n?=?760) in upstate New York. Latent class analysis was used to identify groups of women with similar responses to seven violence measures, including childhood physical and/or sexual violence, experience of partner violence during or just after pregnancy (physical, emotional, verbal), and neighborhood violence (perceived or by ZIP code). Logistic regression and survival analysis were utilized to determine if classes were associated with breastfeeding initiation, duration, and exclusivity, controlling for demographics. Results Exposure to at least one form of violence was high in this sample (87%). We identified 4 classes defined by violence exposure (combining current and historical exposures). Violence exposure patterns differed between racial/ethnic groups, but patterns were inconsistently associated with breastfeeding plans or outcomes. For White women, history of violence exposure increased the likelihood of earlier breastfeeding cessation. By contrast, among Black women, history of violence exposure increased the likelihood of having a breastfeeding plan and initiating breastfeeding. Conclusions for Practice Some differences between violence exposure classes are likely due to the correlation between race/ethnicity and socioeconomic status in the community studied. Additional studies are warranted to better understand how exposure to violence is related to breastfeeding and how best to support women making decisions about intention, initiation, and duration of breastfeeding.     

Neighborhood Disadvantage and Neighborhood Affluence: Associations with Breastfeeding Practices in Urban Areas

Objective To estimate the associations between neighborhood disadvantage and neighborhood affluence with breastfeeding practices at the time of hospital discharge, by race-ethnicity. Methods We geocoded and linked birth certificate data for 111,596 live births in New Jersey in 2006 to census tracts. We constructed indices of neighborhood disadvantage and neighborhood affluence and examined their associations with exclusive (EBF) and any breastfeeding in multilevel models, controlling for individual-level confounders. Results The associations of neighborhood disadvantage and affluence with breastfeeding practices differed by race-ethnicity. The odds of EBF decreased as neighborhood disadvantage increased for all but White women [Asian: Adjusted odds ratio (AOR) 0.82 (95% confidence interval (CI) 0.69–0.97); Black: AOR 0.77 (95% CI 0.70–0.86); Hispanic: AOR 0.78 (95% CI 0.70–0.86); White: AOR 0.99 (95% CI 0.91–1.08)]. The odds of EBF increased as neighborhood affluence increased for Hispanic [AOR 1.19 (95% CI 1.08–1.31)] and White [AOR 1.12 (95% CI 1.06–1.18)] women only. The odds of any breastfeeding decreased with increasing neighborhood disadvantage only for Hispanic women [AOR 0.85 (95% CI 0.79–0.92)], and increased for White women [AOR 1.16 (95% CI 1.07–1.26)]. The odds of any breastfeeding increased as neighborhood affluence increased for all except Hispanic women [Asian: AOR 1.31 (95% CI 1.13–1.51); Black: AOR 1.19 (95% CI 1.07–1.32); Hispanic: AOR 1.08 (95% CI 0.99–1.18); White: AOR 1.30 (95% CI 1.24–1.38)]. Conclusions Race-ethnic differences in associations between neighborhood disadvantage and affluence and breastfeeding practices at the time of hospital discharge indicate the need for specialized support to improve access to services.
