Background:Negative attitudes toward breastfeeding in public have consistently been identified as a key barrier to breastfeeding continuation. In order to design effective social marketing campaigns to improve public attitude toward breastfeeding in public, it is critical to identify segments of the population who are less likely to support this activity, their underlying reasons, and the medium through which they can be reached.Research aim:The aims were to (a) identify the underlying dimensions that drive acceptance or opposition to breastfeeding in public, (b) test whether specific population segments were more or less likely to support breastfeeding in public, and (c) identify suitable media outlets to reach them.Methods:A cross-sectional survey testing agreement with 60 statements was administered online between May 2016 and May 2017 and was completed by 7190 respondents. Exploratory factor analysis was used to identify 12 dimensions driving acceptance or opposition to breastfeeding in public. The influence of demographics and media consumption on attitudes toward breastfeeding in public was tested using Welch’s t tests and one-way analyses of variance (ANOVAs).Results:Acceptance of breastfeeding in public was found to differ with gender, age, religion, and parental and breastfeeding status, but not household income. Support for breastfeeding in public also varied with media consumption habits.Conclusions:This work lays the foundation to design effective social marketing campaigns aimed at increasing public support for breastfeeding in public.

Background:Breastfeeding women are at risk of developing mastitis during the lactation period. Staphylococcus aureus has emerged as the community-acquired pathogen responsible for virulence (methicillin resistance and Panton-Valentine leukocidin toxin producing).Research aim:The aim was to compare the microorganisms responsible for mastitis and breast abscesses during breastfeeding.Methods:This observational study was conducted with a sample of women (N = 60) admitted to our hospital between 2016 and 2018. Participants affected by mastitis and breast abscess were studied and cared for by a multidisciplinary working group. A diagnostic breast ultrasound identified the pathology.Results:Twenty-six participants (43.3%) were affected by mastitis and 34 (56.7%) by breast abscess. The most common microorganism identified was Staphylococcus aureus (S. aureus; mastitis, n = 13; abscesses, n = 24). Methicillin resistance was identified in 21 (44.7%) S. aureus strains: 17 (80.9%) cases of abscess and four (19.1%) cases of mastitis. The median number of months of breastfeeding was smaller in the methicillin-resistant S. aureus (MRSA) cases (median = 3, range = 1–20 months) than in the methicillin-sensitive S. aureus (MSSA) cases (median = 6.5, range = 3–21 months). The Panton-Valentine leukocidin toxin gene was detected in 12 (25.5%) cases (MRSA, n = 8, 66.7%; MSSA, n = 4, 33.3%). Hospitalization was required more frequently in MRSA (n = 8, 38%; five Panton-Valentine leukocidin positive) than in MSSA cases (n = 5, 19%; one Panton-Valentine leukocidin positive). Four women out of the eight MRSA cases (50%) that were Panton-Valentine leukocidin positive stopped breastfeeding during mammary pathologies, three (37.5%) participants continued breastfeeding until the follow-up recall, and one case was lost at follow-up.Conclusion:Clinical severity was probably complicated by the presence of the Panton-Valentine leukocidin toxin, which required hospitalization more frequently.

Background:A woman’s prior breastfeeding history may influence future decisions regarding infant feeding. Few quantitative tools utilizing this information have been demonstrated to predict breastfeeding success.Research aim:To evaluate the efficacy of a prenatal breastfeeding history (BAP) questionnaire administered in prenatal care to predict in-hospital formula supplementation among multiparous women.Methods:This is a prospective observational study of multiparous women with singleton pregnancies who presented to a Baby-Friendly urban tertiary care center for 1st prenatal visit at < 20 weeks’ gestation. The BAP tool generates a numerical score, with higher score (≥ 2) indicating prior successful breastfeeding experiences. The primary outcome was occurrence of non-medically indicated formula supplementation during the postpartum hospital stay. Student’s t test and Pearson’s chi-square test were used to compare continuous and categorical variables. A multivariable logistic regression was performed to assess the relationship of BAP score to formula supplementation. Of 587 women screened, 433 (73.8%) mother–infant dyads were analyzed.Results:Rates of formula supplementation in women with BAP scores ≤ 1 were 67% (156/234) compared with 37% (73/199) in women with higher scores (p < 0.0001). After controlling for race/ethnicity, insurance, and obesity, women with BAP scores of ≤ 1 were 2.6 times more likely to supplement formula than women with higher scores (aOR 2.62, 95% CI [1.70, 4.04], p < .0001).Conclusion:In this prospective validation study, women with negative prior breastfeeding experiences, as evidenced by a lower BAP score, were more likely to supplement formula during the postpartum hospital stay.
