Few studies evaluate the effects of vitamin D status and supplementation on maternal bone mineral density (BMD) during lactation and further lack inclusion of diverse racial/ethnic groups, body mass index (BMI), or physical activity. Determine the effects of vitamin D treatment/status, feeding type, BMI, race/ethnicity, and physical activity on postpartum women's BMD to 7 months. Women with singleton pregnancies beginning 4-6 weeks' postpartum were randomized into two treatment groups (400 or 6400 IU vitamin D/day).

More than a decade ago, two faculty met at a conference. Each talked about how they were charged with leading global health education efforts at their institutions and longed to have an opportunity to share resources and learn from each other. After reaching out to a few other Midwestern colleagues and finding a date, the first Midwest Consortium of Global Child Health Educators meeting was held in Madison, WI.

Vitamin D (vitD) plays a major role in maintenance of bone mineral homeostasis. It is unknown if bone mineral content (BMC) and bone mineral density (BMD) differ between infants who receive direct vitD supplementation and those who receive vitD indirectly via their mother's breast milk, while she received a high dose of vitD. It is hypothesized that there would be no differences in BMC or BMD by treatment group.

To ensure the safety of higher dose vitamin D supplementation in pregnant and lactating mothers, and urinary calcium/creatinine (UCa/Cr) ratios, serum calcium, and serum 25(OH)D concentrations are closely monitored. To achieve optimal maternal and infant vitamin D status, while avoiding hypercalcemia, safety measures assessing vitD supplementation must be reliable. Whether or not this holds true for infants before 7 months of age, remains unknown.

Article Synopsis
  • The study investigates the safety of high-dose vitamin D supplementation (6,400 IU/day) for postpartum women transitioning from breastfeeding to combination feeding and its effects on their infants.
  • Mothers were randomly assigned to one of three vitamin D dosage groups (400, 2,400, or 6,400 IU/day) for 6 months, with multiple safety and sufficiency parameters measured.
  • Results showed that the 6,400 IU/day dose significantly improved maternal vitamin D levels while not affecting infant safety parameters differently across the groups, indicating it is a safe and effective dosage for achieving vitamin D sufficiency in mothers.

Residency programs are increasingly responding to the growing demand for global health (GH) education by forming dedicated GH tracks. These tracks incorporate a targeted curriculum, support best practices surrounding GH electives such as predeparture preparation and post-return debriefing, and encourage meaningful engagement with international and domestic partners. The University of Minnesota's pediatric residency has had a formal GH track since 2005, and although they have shared several curricular components in the literature, they have yet to provide a comprehensive summary of their GH track.

Ninety percent of the world's children live in low- and middle-income countries, where barriers to health contribute to significant child morbidity and mortality. The American Academy of Pediatrics is dedicated to the health and well-being of children. To fulfill this promise, this policy statement defines the role of the pediatrician in global health and provides a specific set of recommendations directed to all pediatricians, emphasizing the importance of global health as an integral function of the profession of pediatrics.

Introduction Maternal exposure to tobacco smoke is associated with shortened breastfeeding duration, but few studies have examined the effects on breastfeeding outcomes of low level exposures to other toxic chemicals. Moreover, it is unclear if passive smoking is associated with duration of breastfeeding. Our objective was therefore to examine the effect of low-level prenatal exposures to common environmental toxins (tobacco smoke, lead, and phthalates) on breastfeeding exclusivity and duration.

Purpose: Many residency programs require residents to complete an academic project as part of a global health (GH) elective. However, there has been little description of the range of projects residents have pursued during GH electives or the extent to which these projects are consistent with proposed best practices.

Method: The authors conducted a document review of 67 written summaries or copies of presentations of academic projects (hereafter, summaries) completed by pediatric and medicine-pediatric residents at the University of Minnesota while on GH electives from 2005 to 2015.

Background: Perfluoroalkyl substances (PFAS) may affect breast development and decrease duration of breastfeeding, thus interfering with the health benefits of breastfeeding. We investigated the association between maternal PFAS exposure and breastfeeding duration.

Methods: We measured PFAS concentrations in maternal serum collected during pregnancy in 2003-2006.

Recent outbreaks of diseases erroneously thought by many to be contained by borders or eliminated by vaccines have highlighted the need for proper training of all residents in global health. Beyond infectious diseases, all pediatricians should know how to care for other conditions in global child health, ranging from malnutrition to the nuances of care for immigrant and refugee children. The call for broader education for pediatric residents in global health has been increasing over the last decade, with all major pediatric organizations underscoring its importance in statement and action.

Background: Breastfeeding rates in the United States are suboptimal. Health professionals (HPs) have a unique opportunity to support breastfeeding because of the frequency and timing of their visits with mothers and infants as well as their call by professional organizations to do so. The objective of this study was to understand HPs' perceived roles and experiences with providing breastfeeding-related care.

Objective: Compare effectiveness of maternal vitamin D3 supplementation with 6400 IU per day alone to maternal and infant supplementation with 400 IU per day.

Methods: Exclusively lactating women living in Charleston, SC, or Rochester, NY, at 4 to 6 weeks postpartum were randomized to either 400, 2400, or 6400 IU vitamin D3/day for 6 months. Breastfeeding infants in 400 IU group received oral 400 IU vitamin D3/day; infants in 2400 and 6400 IU groups received 0 IU/day (placebo).

Objective: To quantify optimal minimum durations of exclusive breastfeeding associated with maintenance of any breastfeeding at 15 time points during the first year of life.

Study Design: Mothers (n = 1189) from the prospective Infant Feeding Practices Study II cohort who initiated exclusive breastfeeding with healthy term infants were included. In a 80:20 split-sample validation study, receiver operating characteristic curves estimated optimal minimum durations of exclusive breastfeeding needed to predict maintenance of any breastfeeding at 15 time points during the first year (n = 951).
