“Seek real partnerships based on mutual interests as opposed to trying to impose a research agenda onto WIC.”
Happy new year! The quote above is from Dr. Pia Chapparo, featured in this issue’s Researcher Spotlight. Chapparo stresses the importance of researchers putting WIC participants and WIC staff at the center of research projects and actively collaborating to conduct research that moves the needle on pressing issues facing WIC. Genuine engagement is key to any productive partnership. This is a theme across content of this issue. We learn about a meeting in Vermont that proactively brought together diverse stakeholders to discuss caseload in WIC, and we consider the value of a health equity lens in both WIC innovations and research.
We have a new section in Research to Practice – Caseload Trends. We will be reporting on national caseload trends and highlighting any agencies that appear to be bucking the downward trend that we’ve become used to seeing in recent years (there are a few!). As always, we provide some research hacks, links to the most recent research publications, and opportunities to share your WIC research. If there are studies or reports you would like us to highlight in the spring issue, please contact Georgia Machell, firstname.lastname@example.org.
Welcome to “Caseload Corner,” a new feature of NWA’s Research to Practice newsletter. Each quarter, we will present the latest WIC participation data as well as recent developments in WIC caseload research and recruitment and retention innovations.
Current Participation Trends
As shown in this chart, participation continued to decline in FY 2018, from a high of 7.14 million in October 2017 to a low of 6.68 million in September 2018. This trend continues the ongoing decline in WIC participation that began in 2011. The overall participation in FY 2018 (the average of all the monthly participation numbers) was 6.87 million, compared to 7.29 million in FY 2017. There were some months in 2018 in which participation increased from the previous month. These included January, May, and August.
The majority of state agencies (76 out of 90) experienced participation declines between 2017 and 2018, which contributed to the national decline. Fourteen state agencies, however, including two geographic states, experienced increased participation during this time. These state agencies include: Colorado, Mississippi, Pleasant Point Passamaquoddy Reservation, Omaha Sioux, Santee Sioux Tribe, Inter-Tribal Council of Nevada, Pueblo of Isleta, Santo Domingo WIC Program, Acoma, Canoncito & Laguna, Seneca Nation, Three Affiliated Tribes, Citizen Potawatomi Nation, Osage Nation, and Cheyenne River Sioux Tribe. This is a promising trend for these state agencies, as many were experiencing participation declines in the previous four years.
The Vermont WIC Program recently held a WIC summit that brought together diverse stakeholders from the state and local levels to discuss innovative strategies to better recruit and retain WIC participants. The summit was part of a larger project that Vermont WIC is currently leading to address participation declines in the state, at the request of the Vermont state legislature. In addition to calling for the summit, the legislature has also directed the Vermont Department of Health to “solicit input on methods of increasing WIC enrollment from current and former WIC participants, as well as WIC-eligible nonparticipants, and the Department for Children and Families through interviews and surveys” and to “present recommended actions” to the legislature by April 1, 2019.
Summit participants included representatives from the Vermont Department of Health (both WIC and non-WIC), the Department of Children and Families, the Vermont Food Bank, community health organizations, local health departments, nonprofit organizations, and others. A representative of the National WIC Association was also in attendance.
The summit, a two-and-a-half hour event, consisted of WIC updates from Vermont WIC state office staff as well as group discussions focused on current strategies, ongoing challenges, and innovative ideas around recruitment and retention of WIC participants. Some challenges discussed by summit participants included:
WIC staff and partners in the room discussed a number of innovative strategies to overcome these and other challenges, some of which have been used in other states but not yet in Vermont, and some of which have been used on a small scale in Vermont but are not yet statewide. Proposed innovations included:
The National WIC Association is excited to see the final report that the Vermont WIC Office presents to the legislature, which will be a culmination of the summit, surveys, and interviews that they are conducting.
Health equity acknowledges historical trauma, environmental conditions, systemic practices, and other factors that prohibit individuals from reaching a universal goal, such as food security. The Achieving Health Equity page on the Robert Wood Johnson Foundation website provides additional helpful information on this topic. Integrating a health equity framework into WIC research and practice will help to bolster existing efforts to identify promising practices for improving the health of WIC participants and the communities where they reside.
Using a collective-impact approach embedded with health equity, local WIC agencies funded through NWA’s Community Partnerships for Health Mothers and Children (CPHMC) project (2014-2017) leveraged technology to share tools and resources, advance and build support for community health initiatives, and to sustain project interventions. These local agencies’ targeted outreach efforts included:
As highlighted in the CPHMC’s project evaluation report, these and other activities from the project endowed WIC staff with new skills, gave them greater experience with community engagement, and helped to raise the profile of WIC. For example, one agency shared that its toolkit would be widely shared with public health partners in their state: “The Healthy Food Bank Toolkit for the food pantries has really been received positively and is in demand. The toolkit is now up on the TCHD website, is soon to be up on the Hunger Free Colorado website, has been promoted across the state in the Hunger Free Food Pantry newsletter, and is going up on the NWA website.”
What impact did these community health projects have on WIC client caseload? NWA staff and the project evaluation team explored this topic, but we didn’t have adequate data to analyze and make a conclusive statement since the question wasn’t included in the original evaluation plan. Anecdotally, several agencies stated that their increased visibility in the community resulted in more referrals and increases in their caseload. Given the heightened focus on WIC recruitment and retention issues, this area is ripe for further research.
Have you or your WIC agency applied a health equity lens to innovations or research that you are conducting? We would love to hear from you. Please contact Quinney Harris, Director of Health Equity and Community Partnerships, at email@example.com.
Do you know where to find WIC participation data, food-cost data, and budget data on the Food and Nutrition Service website? Check out this page from the USDA-Food and Nutrition Service. This data is used by researchers, advocates, and practitioners to better understand trends by state, region, and nationally.
"I believe WIC is a key “equalizer,” working at improving the diets of vulnerable populations at higher risk of obesity and other chronic diseases."
Pia Chaparro is an assistant professor at Tulane University in New Orleans, LA. Originally from Peru and with a graduate degree from the University of Hawaii and PhD from the University of California Los Angeles (UCLA), Chaparro has lived and worked in a number of places. For over eight years, she has been conducting research on WIC, primarily in collaboration with Dr. Shannon Whaley, Director of Research and Evaluation at PHFE WIC in Los Angeles, and Dr. May Wang from UCLA. Chaparro shared some of her insights and expertise on academic and WIC agency partnerships as well as telling us about her most recent research project on the impact of the 2009 WIC food package changes.
What drew you to study WIC?
What are the goals of your most recent research on WIC?
We are using longitudinal administrative data from WIC participants in Los Angeles County between 2003 and 2016 from the Data Mining Project, evaluating weight-for-height z-scores (WHZ) growth trajectories between 0 and 4 years of age and obesity risk at 4 years (obesity defined as BMI-for-age≥95th percentile) for children exposed to the old food package (before October 1, 2009) vs. those exposed to the new food package (after October 1, 2009).
Exposure to the new food package (compared to the old) from 0 to 4 years is associated with healthier growth trajectories (i.e., WHZ closer to the mean of 0 and further from the overweight category) and a 10-12% lower obesity risk at age 4 (10% for girls and 12% for boys).
We are currently working on investigating if the type of infant food package received from 0-12 months could explain the observed improved obesity outcomes among children exposed to the new food package. But there are many components contained in this “food package change” – impacting both mothers’ and children’s diet and nutritional status as well as the food environment – and we don’t know which of these components (or if all) are responsible for the decreased obesity risk observed. In addition, we use food package issuance as a proxy for diet consumption, but it would be useful to pair the issuance data with redemption data.

The American Public Health Association (APHA) Food and Nutrition Section (FN) invites you to view the 2019 Call for Abstracts and enter a submission. Abstract submissions are a critical part of developing an innovative and exciting program.
The FN Section invites abstracts and full session proposals for the 2019 APHA Annual Meeting, which will feature the theme of "Creating the Healthiest Nation: For Science. For Action. For Health." November 2- 6, 2019, in Philadelphia, PA.
APHA will be accepting submissions representing a wide range of food and nutrition topics. In recognition of the 2019 APHA Annual Meeting theme, APHA is looking for submissions that address the implementation of food and nutrition-related research, policies, advocacy, and programming. It is particularly interested in proposals that apply an equity lens to work focused on food and nutrition.
Please circulate the Call for Abstracts link and announcement to your relevant networks. The Call for Abstracts will remain open until February 23, 2019. APHA looks forward to receiving your submissions!
Below are two testimonials from NWA members who attended the 2018 APHA conference:
"This year APHA was particularly fantastic. The Food & Nutrition and Maternal & Child Health sections were exceptionally well organized with some excellent sessions marrying research and practice. It was a great venue to connect with public health professionals from around the country doing work that really complements WIC practice. It was also a place to expand my own knowledge and understanding of many important public health issues of the day that touch our lives and lives of WIC participants but aren’t part of my every day work but are things I think are important to know more about - from gun violence to implicit bias to changes in immigration policy." -- Shannon Whaley, PHFE WIC
"APHA is an outstanding forum where so many of WIC’s public health nutrition and maternal child health concerns come together and are viewed through an essential health equity lens. I would encourage all WIC practitioners to consider attending and/or presenting at APHA." -- Kathleen Merchant, SDSU Research Foundation WIC Program
