TOTT STUDY -Targeting Behavioral Triggers of Overfeeding: Obesity Prevention in Older Infants and Toddlers at WIC (2010-2013)
The UC Davis Human Lactation Center partnered with the California WIC Program on a project designed to extend, expand, and evaluate behavioral nutrition education, using the materials developed as part of the Toddler Project, to address the needs of caregivers of older infants (7-12 months of age) and toddlers (to 18 months of age). Through expansion of the “baby behavior” training and education, designed to promote positive parent-child interaction and healthy feeding practices, we aimed to prevent the establishment of feeding behaviors that are strongly associated with child overweight and obesity. The project assessed the impact of the intervention on knowledge, attitudes, and behaviors of staff and participants. The TOTT Study was funded through a USDA Special Project Grant.
Perceptions of Infant Formula Additives from Moms Participating in the California Women, Infants, and Children (WIC) Program (2010-2013)
Many women in the United States initiate breastfeeding, but less than half continue to breastfeed after three months. More specifically, exclusive breastfeeding rates are low among low-income women. At the same time, advertising of infant formula is prevalent and increasing. There are many external factors that influence a woman’s decision to breastfeed, including direct and indirect marketing of infant formulas. Such marketing strategies include magazine advertisements, prenatal formula promotion materials, and hospital discharge packs. Current research suggests that mass media marketing discourages breastfeeding by diffusing information about infant formula products and reinforcing factors that oppose breastfeeding. Formula was originated for infants who needed extra nourishment or whose mothers could not nurse. However, formula is now marketed to almost all women, especially low-income women who are less likely to breastfeed their children. The purpose of this study, conducted in partnership with the California WIC Association (CWA), was to characterize understanding of marketing claims related to infant formula additives and to determine the impact of infant formula marketing on this population.
“Just in Case” A Qualitative Study of Reasons Why Mothers Request Formula in the Hospital (2008-Present)
In 2008, staff of the UC Davis Human Lactation Center began a study aimed at learning more about why mothers of healthy breastfeeding infants request formula during their hospital stay. This project was initiated by Katie Bowman, MAS, IBCLC during her graduate studies at UC Davis. A series of focus groups were conducted at various WIC sites in Northern California, and we are currently in the process of analyzing and reporting the data. Results of this qualitative research will be used to inform policy and develop messages to support and assist mothers who have made the decision to breastfeed their infants.
Toddler Study – Triggers of Overfeeding among Older Infants and Toddlers (2010-2011)
Building upon the success of the FitWIC Baby Behavior Study, staff of the UC Davis Human Lactation Center are partnering with California WIC on a new project to identify triggers of overfeeding of infants and toddlers from 6 to 18 months of age. While crying and waking are likely to be triggers of overfeeding among parents of older infants and toddlers, reasons for crying and waking among older infants differ from those of of younger infants. In an effort to identify the concerns that drive parents of older infants and toddlers to believe that their children are hungry or need inappropriate foods and fluids, caregivers will be asked about their infant feeding decisions and materials and messages will be developed to address their concerns.
Starting in the fall of 2006, staff of the UC Davis Human Lactation Center began a 3-year educational intervention project designed to increase WIC participants’ knowledge of normal infant behavior in order to 1) promote positive interactions among infants and caregivers and 2) prevent overfeeding in infancy. The intervention resulted in an increased satisfaction with WIC education, an increase in the use of the exclusive breastfeeding food package at intervention sites, and reductions in formula use, particularly in the first month (this study was conducted prior to the food package change). The final report and all materials developed for the intervention are available through the WICWorks site at http://www.nal.usda.gov/wicworks/Sharing_Center/gallery/FitWICBaby.htm
Cross-Case Comparison of Breastfeeding Support Models throughout California (2005)
In the summer of 2005, staff of the UC Davis Human Lactation Center conducted a cross-case comparison of various models of breastfeeding support currently used in California (including cost information). The objectives of this study were to 1) develop a detailed qualitative, descriptive summary for each program and to 2) identify key factors associated with successful programs. The ultimate goals of this study were 1) to expand the evidence-base related to optimal systems of health care for breastfeeding mothers and infants, 2) share key elements of active, successful programs with interested agencies and community members (which was done in October 2005), and 3) identify factors associated with successful programs for use in development of intervention trials.
Sources of Infant Feeding Information for Low Income Women (2005)
In the summer of 2005, staff of the UC Davis Human Lactation Center conducted a multi-center, qualitative study in Northern California as a follow-up to the original study conducted in 2003 (also funded by WIC), which examined the barriers to compliance with infant feeding recommendations among low-income women. The short-term goal of this study was to (1) obtain, through focus groups, sources of infant feeding information for low-income mothers and (2) how mothers decide what information is “credible’ and helpful to them.

Examining Barriers to Compliance with Infant Feeding Recommendations among Low-income Women (2003-2004)
In the spring of 2003, staff of the UC Davis Human Lactation Center conducted a multi-center, qualitative study of WIC participants in the Sacramento area. The short-term goal of this study was to better understand why non-optimal infant feeding practices occur among low-income women despite extensive education and counseling provided by WIC agencies. The aim of this project was to conduct pilot focus groups among culturally diverse WIC participants, in order to determine whether or not the elements of the Theory of Planned Behavior (TPB) are relevant to this population and to identify culturally specific factors that affect infant feeding behavior in the first 6 months postpartum.

California Statewide Breastfeeding Needs Assessment
From October 2001 to May 2002, center faculty, in cooperation with the UC Davis Division of Agriculture and Natural Resources Maternal and Infant Nutrition Workgroup, conducted a needs assessment using the resources of the 37 active breastfeeding coalitions throughout the state of California; all but 2 agreed to participate. A survey was mailed to the designated contact person and the coalition members were asked to discuss and record their responses to the questions during one of their regular meetings. Approximately 320 people participated in the survey, representing a cross-section of providers of breastfeeding support including hospital nurses, public health nurses, lactation consultants, WIC nutritionists, clinical dietitians, social workers, and community health workers. The results represent these providers’ views on the state of breastfeeding support services in California.
WHO Multicentre Growth Study (1999)
In 1999, Human Lactation Center faculty and staff conducted a large prospective study of lactation and infant growth sponsored by the World Health Organization and co-funded by the USDA and National Institutes of Health. The City of Davis was the North American site of this worldwide effort to gather data for a new international child growth reference.
More information about this study is available at http://www.who.int/childgrowth/mgrs/en/.
Risk Factors Study (1999)
In this study, a community-based sample of all residents of Davis who gave birth in 1999, was used to examine risk factors for breastfeeding difficulties in the first month postpartum.
