Focusing on Excessive Gestational Weight Gain through Weight Tracking Among Participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Southern California
Background and Purpose: Studies have shown that maternal obesity and excessive gestational weight gain (GWG) lead to adverse health outcomes for the mother and her offspring. Yet, knowledge of the best way to intervene is still lacking. The objective of this study was to develop, pilot and evaluate a sustainable intervention to prevent excessive GWG among participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in southern California. Methods: We conducted a prospective cohort study where the intervention group received an individual education program that included a GWG tracker. The historical control group was a group of women from the same WIC site who gave birth before the start of the intervention, therefore did not receive the intervention. Chi-square tests and t-tests were used to compare characteristics of the control and intervention groups and the proportions of women exceeding the Institute of Medicine (IOM) recommendations for GWG. Results: The impact of the intervention was strongest for overweight women. 62.5% of the control group gained more than the recommended amount compared to 48.6% in the intervention group. Conclusion: A simple weight tracking intervention could be a cost-neutral way to help WIC participants avoid excessive GWG
Potential Overfeeding among Formula Fed Special Supplemental Nutrition Program for Women, Infants and Children Participants and Associated Factors
Background: The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) provides enough formula to meet the known nutritional needs of infants up to 6 months of age whose mothers report not breastfeeding, but many mothers report WIC providing insufficient formula, indicating potential overfeeding.
Objective: To estimate the prevalence of potential overfeeding among formula-feeding WIC participants and identify associated factors.
Methods: Potential overfeeding was identified among participants of the longitudinal Infant and Toddler Feeding Practices Study-2 (ITFPS-2) receiving the fully formula feeding WIC infant package at 1 month of age (n = 1235, weighted n = 197 079). Associations of potential overfeeding with caloric intake, weight and participant characteristics were assessed.
Results: Potential overfeeding was identified among 37.41% (95% CI = 33.57- 41.25%) of fully formula-feeding infants. Potentially overfed infants were 0.18 kg heavier (P-value = .01), consumed 26 more calories daily (P-value = .004) and were more likely Non-Hispanic White or English-speaking Hispanic (P-value = .007) and highly active at 5 months of age (P-value = .01). Mothers of potentially overfed infants were less likely to agree that breastfeeding is easier than bottle feeding, only mothers can feed breastfed infants, turning away from the bottle indicates satiation, and crying always indicates hunger (P-values .04, .002, .04 and .04 respectively), and more likely to report WIC provides insufficient formula early (1-5 months, P-value \u3c.0001) and late (6-13 months, P-value = .007) in infancy.
Conclusions: Potential overfeeding occurs in 37% of fully formula-feeding infant WIC-participants \u3c6 months old. Mothers of these infants may benefit from additional education about the formula needs of their infants and how to recognize infant satiation cues
A Qualitative Study of Breastfeeding and Formula-Feeding Mothers’ Perceptions of and Experiences in WIC
Objective: To explore Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants’ perspectives about why formula-fed infants are less likely to be recertified at 1 year compared with breastfed infants.
Design: Four focus groups of WIC mothers, stratified by language spoken (English or Spanish) and feeding mode (breastfeeding [BF] or formula-feeding [FF]).
Setting: Two WIC sites within Los Angeles County, CA.
Participants: Mothers of 6- to 12-month-old infants (n = 31) in the WIC program.
Phenomenon of Interest: Mothers’ perceptions of (1) how WIC supports BF and FF mothers; and (2) experiences of FF mothers in WIC, with a focus on how these experiences may affect desire to recertify their infant in WIC at age 1 year.
Analysis: Thematic analysis of verbatim transcripts.
Results: Mothers in all focus groups discussed the perceived positive value of BF support, food assistance, nutrition education, referrals, convenient WIC services, and social support from staff. Themes related to experiences of FF mothers included feeling judged for not BF, perceptions of WIC as a formula provider, and perceived difficulties obtaining formula. Mothers indicated that these experiences affected motivations to recertify.
Conclusions and Implications: Although WIC provides important and effective support to low-income families, especially related to BF, some FF mothers may feel underserved with respect to support for their feeding decisions
A Non-Parametric and Entropy Based Analysis of the Relationship between the VIX and S&P 500
A WIC-Based Curriculum to Enhance Parent Communication with Healthcare Providers
The objectives describe a curriculum to support parent-provider communication about child development, and to demonstrate its impact and effectiveness when delivered by staff from the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). A curriculum was developed by a university-WIC partnership for a WIC center-based health education class to teach parents about child development and how to talk to their child's doctor about development. During a 90-min training session, university pediatricians used this curriculum and trained WIC paraprofessionals to conduct a 20-30 min center-based education session. WIC paraprofessionals completed an on-line survey to obtain their demographic characteristics, and their attitudes and perceptions about the training sessions and their experiences teaching the center-based health education session to parents. Approximately 500 WIC paraprofessionals received the 90-min training session across 60 centers in the Public Health Foundation Enterprises WIC Program in Southern California. About 250 WIC paraprofessionals completed the on-line survey and over 80 % of WIC staff reported that they had learned new information about child development as a result of the training, and 87 % of the WIC staff reported that the training was sufficient to feel comfortable teaching the class content to parents. We demonstrated the ability to build WIC paraprofessional capacity to promote parental participation in child developmental surveillance and communication with their child's doctor. With appropriate training, WIC staff are interested in supporting population-based efforts to improve parent-physician communication about child development that can complement WIC's existing maternal and child health topics

Methods highlighted in Q-Chem 5 include a suite of tools for modeling core-level spectroscopy, methods for describing metastable resonances, methods for computing vibronic spectra, the nuclear–electronic orbital method, and several different energy decomposition analysis techniques. High-performance capabilities including multithreaded parallelism and support for calculations on graphics processing units are described. Q-Chem boasts a community of well over 100 active academic developers, and the continuing evolution of the software is supported by an “open teamware” model and an increasingly modular design
Strategies to Promote Responsive Bottle-feeding in WIC Predict Less Frequent Use of Food to Soothe and Healthier Weight Status for Infants with Negative Temperaments
Background: Infants with greater temperamental negative affectivity are at higher risk for overfeeding and excess weight gain.
Objective: To examine whether strategies to promote responsive bottle-feeding within WIC promoted healthier maternal feeding practices and infant weight status among infants with greater negative affectivity.
Methods: Secondary analysis of data from a matched-pair cluster randomized trial. Policy, systems and environmental change (PSE) strategies to promote responsive bottle-feeding were implemented at three WIC clinics; these clinics were compared with three matched control clinics. Linear mixed models tested whether infant negative affectivity interacted with PSE strategies to predict feeding and weight outcomes when infants were 4–6 months old.
Results: Significant interactions between infant negative affectivity and PSE strategies were noted. Among infants with high negative affectivity, mothers in PSE clinics reported less frequent use of food to soothe (p = 0.009) compared with mothers in control clinics. Among infants with moderate (p = 0.008) or high (p = 0.029) negative affectivity, infants in PSE clinics had healthier weight status compared with infants in control clinics.
Conclusions: Promotion of responsive bottle-feeding is an effective way to support WIC mothers and reduce risk for overfeeding and excess weight gain, particularly for mothers of infants with greater negative affectivity
Brief Intervention for Alcohol Use by Pregnant Women
Objectives. We examined the efficacy of brief intervention as a technique to help pregnant women achieve abstinence from alcohol. A second aim was to assess newborn outcomes as a function of brief intervention. Methods. Two hundred fifty-five pregnant women who were participants in the Public Health Foundation Enterprises Management Solutions Special Supplemental Nutrition Program for Women, Infants, and Children and who reported drinking alcohol were assigned to an assessment-only or a brief intervention condition and followed to their third trimester of pregnancy. Brief intervention consisted of 10- to 15-minute sessions of counseling by a nutritionist, who used a scripted manual to guide the intervention. Newborn outcomes of gestation, birth-weight, birth length, and viability were assessed. Results. Women in the brief intervention condition were 5 times more likely to report abstinence after intervention compared with women in the assessment-only condition. Newborns whose mothers received brief intervention had higher birthweights and birth lengths, and fetal mortality rates were 3 times lower (0.9%) compared with newborns in the assessment-only (2.9%) condition. Conclusions. The success of brief intervention conducted in a community setting by nonmedical professionals has significant implications for national public health policies
Lower redemption of monthly Special Supplemental Nutrition Program for Women, Infants and Children benefits associated with higher risk of program discontinuation
Abstract
Objective:
To determine whether Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food benefit redemption is associated with discontinuing WIC participation, failure to recertify, overall and by race/ethnicity-language preference and participant category.
Design:
Retrospective cohort study, using multivariable modified Poisson regression to determine risk ratios (RR) and 95 % CI for associations between household-level food benefit redemption (interval-scaled benefit redemption percent, averaged across WIC benefit subcategories, for the final 3, 6 and 12 months of certification) and failure to recertify in WIC, overall and within strata of race/ethnicity-language preference and participant category.
Setting:
WIC administrative data collected November 2019–July 2021 in Southern California.
Participants:
WIC-participating children ages 0–3 years at initial certification from November 2019 to May 2020 (n 41 263).
Results:
In all time periods, and for all subgroups, every 10 % lower food benefit redemption was associated with increased risk of failure to recertify. Among households without missing food benefit data, failure to recertify risk peaked at 505 % higher (RR = 6·05, 95 % CI (5·63, 6·51)) in households with average 12-month redemption <10 % compared with households with ≥70 % redemption.
Conclusions:
Lower WIC benefit redemption was associated with higher risk of failing to recertify among participants. Focused nutrition education around benefit redemption may improve WIC retention and child health through incremental increases in food benefit redemption
WIC Participants\u27 Perceptions of COVID-19-Related Changes to WIC Recertification and Service Delivery
Many Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics implemented alternatives to in-person service delivery in response to the COVID-19 pandemic, including virtual visits and electronic document sharing. The objective of this cross-sectional study was to describe WIC participants’ experiences with remote service delivery and recertification during the pandemic. Participants included mothers and infants who participated in a WIC-based intervention between June 2019-August 2020. All participants (N = 246) were invited to complete a follow-up survey between November 2020-February 2021; 185 mothers completed the survey. The survey assessed sociodemographics, employment, food security, experiences with remote WIC recertification and service delivery, and experiences with obtaining WIC foods during the pandemic. Average age for mothers was 29.2 ± 6.3 years and for infants was 17.7 ± .2 months; 80% (n = 147) identified as Hispanic. Approximately 34% (n = 62) of participants reported very low or low food security and 40% (n = 64) had difficulties buying WIC foods during the pandemic. Among participants who recalled providing documentation of income and address virtually, the majority felt comfortable providing information via email (60%) and text messaging (72%). Participants reported high levels of satisfaction with remote methods of service delivery, as well as overall satisfaction with the WIC program during the pandemic. While ~ 25% of study participants preferred for all WIC services to remain remote, 75% still desired at least some in-person contact with WIC staff after the pandemic. In conclusion, remote methods of WIC service delivery addressed existing barriers to WIC participation and were well-received by study participants
