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.

<p><strong>BACKGROUND: </strong>Breastfeeding expectations predict breastfeeding duration. The extent to which expectations for duration are met remains unknown.</p>

<p><strong>OBJECTIVES: </strong>To evaluate prospective measures of expected breastfeeding duration, changes in expectations over time, and factors associated with meeting expectations.</p>

<p><strong>METHODS: </strong>The Infant Feeding Practices Study II followed women from late pregnancy to 1 year postpartum. Expected breastfeeding duration was assessed 5 times. Logistic regression identified factors associated with met prenatal expectations. Subgroup analysis compared met prenatal expectations to satisfaction with breastfeeding duration.</p>

<p><strong>RESULTS: </strong>One-year postpartum, 34.7% of 1802 participants had met prenatal expected breastfeeding duration, and 23.9% were still breastfeeding. Fifty-eight percent of women met expectations stated at 7 months postpartum. Modifiable risk factors associated with meeting prenatal expectations included early regular breast pump use (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.18-2.07). Return to work was negatively associated with met expectations (return by 6 weeks postpartum: OR, 0.48; 95% CI, 0.33-0.71; later return: OR, 0.73; 95% CI, 0.56-0.95). Among those who reported on satisfaction with duration (n = 1226), 40.4% were satisfied. Satisfaction was associated with meeting expectations (OR, 10.56; 95% CI, 7.67-14.55), but expectation and satisfaction measures were not equivalent. Elevated body mass index and depressive symptoms at 2 months postpartum were negatively associated with both measures.</p>

<p><strong>CONCLUSION: </strong>Most participants did not meet prenatal or postnatal expectations for breastfeeding duration and were unsatisfied with duration. However, at 12 months, more participants felt they had met their expectations and were satisfied with their breastfeeding duration than were actually breastfeeding. Therefore, women may perceive greater breastfeeding progress than suggested by Healthy People 2020 benchmarks.</p>

<p><strong>OBJECTIVE: </strong>Most US women intend and initiate breastfeeding, yet many do not breastfeed as long as desired. Not meeting one's own prenatal expectations is a plausible mechanism for the previously observed association between lack of breastfeeding and postpartum depression (PPD). This study explored whether meeting prenatal expectations for exclusive breastfeeding was associated with PPD symptoms.</p>

<p><strong>METHODS: </strong>The 2005 Infant Feeding Practices Study II (IFPSII) followed US mothers, primarily white women with higher education and income, from midpregnancy to 1 year postpartum. Depressive symptoms were defined as Edinburgh Postnatal Depression Scale (EPDS) of 10 or higher, measured at 2 months postpartum. Logistic regression analysis evaluated the odds of maternal depressive symptoms as a function of meeting prenatal expectations for exclusive breastfeeding, accounting for breastfeeding behavior, demographics, and postnatal experiences.</p>

<p><strong>RESULTS: </strong>Among IFPSII participants, 1501 intended exclusive breastfeeding and completed the EPDS. At 2 months, 589 (39.2%) had met prenatal expectations for exclusive breastfeeding. EPDS was 10 or higher for 346 participants (23.1%). Adjusted odds of depressive symptoms were lower among women meeting prenatal exclusive breastfeeding expectations versus those who were not (odds ratio 0.71, 95% confidence interval 0.52-0.96). In subgroup analysis, there was no association between met expectations and depressive symptoms among women with lower incomes (&lt;200% federal poverty level) or those intending mixed breast and formula feeding.</p>

<p><strong>CONCLUSIONS: </strong>Among middle- and higher-income women who intended exclusive breastfeeding, those meeting prenatal breastfeeding expectations reported fewer PPD symptoms at 2 months postpartum. Clinician understanding and support of maternal expectations may improve maternal mental health.</p>
