Associations of Increased WIC Benefits for Fruits and Vegetables With Food Security and Satisfaction by Race and Ethnicity.

Introduction: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutrition support for racially and ethnically diverse populations. In 2021, the monthly cash value benefit (CVB) for the purchase of fruits and vegetables increased from $9 to $35 and was later adjusted to $24. This study investigated, by racial and ethnic groups, whether CVB increases were associated with increases in CVB redemption, household food security, child fruit and vegetable intake, satisfaction with CVB amount, and likelihood of continued participation in WIC if the CVB returned to $9 per month. Methods: We conducted a longitudinal study of WIC participants (N = 1,770) in southern California at 3 time points, from April 2021 through May 2022; the CVB amount was $9 at baseline, $35 at Survey 2, and $24 at Survey 3. Racial and ethnic groups were Hispanic English-speakers, Hispanic Spanish-speakers, non-Hispanic Asian, non-Hispanic Black, non-Hispanic Other, and non-Hispanic White. We used mixed-effect and modified Poisson regressions to evaluate outcomes by group. Results: At baseline, groups differed significantly in dollars of CVB redeemed, percentage of CVB redeemed, household food security, and satisfaction with CVB amount. After the increase in CVB, we found increases in all groups in CVB redemption, household food security, and satisfaction. Non-Hispanic Black and Hispanic English-speaking groups, who had low levels of satisfaction at baseline, had larger increases in satisfaction than other groups. Reported likelihood of continued WIC participation if the monthly CVB returned to $9 also differed significantly by group, ranging from 62.5% to 90.0%. Conclusion: The increase in CVB for children receiving WIC benefited all racial and ethnic groups. Continued investment in an augmented CVB could improve health outcomes for a racially and ethnically diverse WIC population.

The Infant Diet Quality Index Predicts Dietary and Adiposity Outcomes in US Children 2 to 4 years old.

BACKGROUND: Healthy nutrition during the first year of life is critical for optimal growth and development. Limited techniques are available to assess diet quality in infancy, and few have been shown to be predictive of dietary and adiposity outcomes in low-income children. OBJECTIVE: The objectives of this study were to construct an Infant Diet Quality Index (IDQI) to assess the diet quality from birth to 12 mo and to determine whether the IDQI exhibits predictive validity by estimating the longitudinal associations of IDQI scores with diet quality and weight status at 2 to 4 y. DESIGN: Data were analyzed from the longitudinal Women, Infants, and Children Infant and Toddler Feeding Practices Study-2 (unweighted, n = 2858; weighted. N = 392,439) using one 24-h dietary recall and survey responses during infancy. The newly constructed IDQI consists of 16 equally-weighted components: 1) breastfeeding duration; 2) exclusive breastfeeding; age of first introduction of: 3) solids, 4) iron-rich cereals, 5) cow milk, 6) sugar-sweetened beverages, 7) salty/sweet snacks, 8) other drinks/liquids, and 9) textured foods; frequency of consuming 10) fruit or 11) vegetables; frequency of consuming different 12) fruit or 13) vegetables; 14) nonrecommended bottle-feeding practices; 15) use of commercial baby foods; and 16) number of meals and snacks. Regression analysis was used to estimate associations between the total IDQI score (range, 0-1) and Healthy Eating Index-2015 (HEI-2015) scores and body mass index z-scores (BMIz) at 2 to 4 y of age, adjusted for covariates (e.g., child age, sex and race/ethnicity; maternal education level, etc.) RESULTS: The total IDQI score was positively associated with HEI-2015 at the age of 2 y (ß = 16.7; 95% CI: 12.6, 20.9; P < 0.001), 3 y (ß = 14.5; 95% CI: 8.1, 21.0; P < 0.001), and 4 y (ß = 15.4; 95% CI: 8.4, 22.4; P < 0.001); and negatively associated with BMIz at the age of 2 y (ß = -1.24; 95% CI: -2.01, -0.47; P = 0.002) and 4 y (ß = -0.92; 95% CI: -1.53, -0.30; P = 0.003). CONCLUSIONS: The IDQI has predictive validity for diet quality and weight status in low-income US children.

Differences in Infant Diet Quality Index by Race and Ethnicity Predict Differences in Later Diet Quality.

BACKGROUND: Racial and ethnic disparities in infant-feeding practices may negatively influence diet quality and health. OBJECTIVES: This study investigated the racial, ethnic, and language (English or Spanish) differences in infant diet quality, later diet quality, and weight status at 2-5 y, and whether these differences were explained through infant diet quality among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). METHODS: Using the WIC Infant and Toddler Feeding Practices Study-2 (unweighted n = 2663; weighted n = 362,712), relationships between the Infant Dietary Quality Index (IDQI; range 0-1) and Healthy Eating Index-2020 (HEI-2020; range 0-100) and BMI z-score (BMIz) at 2-5 y were analyzed by race, ethnicity, and language preference [Hispanic Spanish-speaking, Hispanic English-speaking, non-Hispanic (NH) White, and NH Black participants]. Statistical interaction between IDQI and each group was evaluated in multivariable models. The mediation of each group through the IDQI was assessed using causal mediation methods. RESULTS: Differences in IDQI [mean (standard deviation)] were observed between Hispanic Spanish-speaking participants [0.41 (0.10)], Hispanic English-speaking participants [0.37 (0.10)], NH White participants [0.36 (0.10)], and NH Black participants [0.35 (0.09)], P < 0.001. Differences in HEI-2020 occurred at 2-5 y, with the Hispanic Spanish-speaking participants having consistently higher HEI-2020 scores. Differences in BMIz were observed at 5 y, with higher scores among Hispanic Spanish-speaking participants. Interaction between race, ethnicity, and IDQI was observed for all outcomes except for BMIz at 3 y. Through mediation, IDQI explained 13%-20% of the difference in HEI-2020 scores between Hispanic Spanish-speaking and NH White participants at 2-5 y. IDQI explained 22%-25% of the difference in HEI-2020 scores between the Hispanic Spanish-speaking and NH Black participants at 4 y and 5 y. CONCLUSIONS: Higher infant diet quality scores observed in Hispanic Spanish-speaking participants explain some of the racial and ethnic differences observed in later diet quality, suggesting that improving infant diet quality may help reduce diet disparities during early childhood.

Dietary inflammatory index and cardiovascular disease risk in Hispanic women from the Women's Health Initiative.

BACKGROUND: To evaluate the association between the dietary inflammatory index (DII®) and incident cardiovascular disease (CVD) in Hispanic women from the Women's Health Initiative (WHI), and to determine if body mass index (BMI) interacted with the DII scores. METHODS: Secondary analysis of baseline dietary data and long-term CVD outcomes among 3,469 postmenopausal women who self-identified as Hispanic enrolled in WHI. DII scores were calculated from self-administered food frequency questionnaires. The CVD outcomes included coronary heart disease (CHD) and stroke. Stratified Cox regression models were used to assess the relationship between DII scores and CVD in women with and without obesity. Models were adjusted for age, lifestyle risk factors, known risk factors, and neighborhood socioeconomic status. RESULTS: The incidence of CHD was 3.4 and 2.8% for stroke after a median follow-up of 12.9 years. None of the DIIs were associated with CVD risk in this sample of Hispanic women. BMI interacted with the DII (p < 0.20) and stratified models showed that the associations between the DII and CVD were only significant in women with overweight (p < 0.05). In this group, higher DII scores were associated with a higher risk of CHD (HR 1.27; 95% CI: 1.08, 1.51) and a higher risk of stroke (HR 1.32; 95% CI: 1.07, 1.64). CONCLUSION: Among postmenopausal Hispanic women with overweight, greater adherence to pro-inflammatory diets was associated with higher risk of CVD. Additional research is needed to understand how to promote long-term heart-healthy dietary habits to reduce inflammation and prevent CVD in at-risk Hispanic women.

Household food insecurity and children's physical activity and sedentary behaviour in the United States: the Healthy Communities Study.

OBJECTIVE: To examine associations between household food insecurity and children's physical activity and sedentary behaviours. DESIGN: Secondary analysis was conducted on the Healthy Communities Study, an observational study from 2013 to 2015. Household food insecurity was assessed by two items from the US Department of Agriculture's 18-item US Household Food Security Survey Module. Physical activity was measured using the 7-d Physical Activity Behaviour Recall instrument. Data were analysed using multilevel statistical modelling. SETTING: A total of 130 communities in the USA. PARTICIPANTS: In sum, 5138 US children aged 4-15 years. RESULTS: No associations were found for the relationship between household food insecurity and child physical activity. A significant interaction between household food insecurity and child sex for sedentary behaviours was observed (P = 0·03). CONCLUSIONS: Additional research capturing a more detailed assessment of children's experiences of food insecurity in relation to physical activity is warranted. Future studies may consider adopting qualitative study designs or utilising food insecurity measures that specifically target child-level food insecurity. Subsequent research may also seek to further explore sub-group analyses by sex.

Factor Analysis Reduces Complex Measures of Nutrition Environments in US Elementary and Middle Schools into Cohesive Dimensions in the Healthy Communities Study.

BACKGROUND: Although it has been recommended that schools be the hub of efforts to improve child nutrition, research describing school nutrition environments in US public schools and their associations with child health is limited. OBJECTIVE: This study aimed to evaluate the applicability of factor analysis methods to characterize school nutrition environments by identifying underlying factors, or dimensions, in the observed data and to examine the relation between school nutrition environment dimensions and child anthropometric and dietary outcomes. METHODS: This study examined a cross-sectional sample of 4635 US children aged 4-15 y from 386 US elementary and middle schools from the Healthy Communities Study (2013-2015). Data collected from schools were used to create 34 variables that assessed the school nutrition environment. To identify dimensions of school nutrition environments, exploratory factor analysis was conducted with orthogonal rotation, and factor scores were derived using methods to account for sporadic missing data. Mixed-effects regression models adjusted for child- and community-level variables and clustered by community and school examined the associations of school nutrition environment dimensions with child anthropometric and dietary outcomes. RESULTS: Six dimensions of school nutrition environments were derived: nutrition education, food options, wellness policies, dining environment, unhealthy food restriction, and nutrition programs. The unhealthy food restriction dimension was negatively associated with added sugar intake (ß = -1.13, P < 0.0001), and the wellness policies dimension was positively associated with waist circumference (ß = 0.57, P = 0.01). CONCLUSIONS: This study demonstrates how factor analysis can reduce multiple measures of complex school nutrition environments into conceptually cohesive dimensions for purposes of assessing the relation of these dimensions to student health-related outcomes. Findings were mixed and indicate that the restriction of unhealthy foods in school is associated with lower added sugar intake. Additional, longitudinal studies are needed to substantiate the utility of this method for identifying promising school nutrition environments.

Household Food Insecurity is Associated with Higher Adiposity among US Schoolchildren Ages 10-15 Years: The Healthy Communities Study.

BACKGROUND: Limited research exists on the relationship between food insecurity and children's adiposity and diet and how it varies by demographic characteristics in the United States. OBJECTIVE: The aim of this study was to assess the relationship between household food insecurity and child adiposity-related outcomes, measured as BMI (kg/m2) z score (BMI-z), weight status, and waist circumference, and diet outcomes, and examined if the associations differ by age, sex, and race/ethnicity. METHODS: Data collected in 2013-2015 from 5138 US schoolchildren ages 4-15 y from 130 communities in the cross-sectional Healthy Communities Study were analyzed. Household food insecurity was self-reported using a validated 2-item screener. Dietary intake was assessed using the 26-item National Cancer Institute's Dietary Screener Questionnaire, and dietary behaviors were assessed using a household survey. Data were analyzed using multilevel statistical models, including tests for interaction by age, sex, and race/ethnicity. RESULTS: Children from food-insecure households had higher BMI-z (ß: 0.14; 95% CI: 0.06, 0.21), waist circumference (ß: 0.91 cm; 95% CI: 0.18, 1.63), odds of being overweight or obese (OR: 1.17; 95% CI: 1.02, 1.34), consumed more sugar from sugar-sweetened beverages (ß: 1.44 g/d; 95% CI: 0.35, 2.54), and less frequently ate breakfast (ß: -0.28 d/wk; 95% CI: -0.39, -0.17) and dinner with family (ß: -0.22 d/wk; 95% CI: -0.37, -0.06) compared to children from food-secure households. When examined by age groups (4-9 and 10-15 y), significant relationships were observed only for older children. There were no significant interactions by sex or race/ethnicity. CONCLUSIONS: Household food insecurity was associated with higher child adiposity-related outcomes and several nutrition behaviors, particularly among older children, 10-15 y old.

Diet Quality of US Infants and Toddlers 7-24 Months Old in the WIC Infant and Toddler Feeding Practices Study-2.

Background: Despite the important implications of childhood dietary intakes on lifelong eating habits and health, data are lacking on the diet quality of low-income infants and toddlers. Objective: The objective of this study was to characterize diet quality in low-income US infants and toddlers. Methods: A national observational study was conducted of 7- to 12-mo-old (n = 1261), 13-mo-old (n = 2515), and 24-mo-old (n = 2179) children enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) prenatally/at birth from 2013 to 2016. The study used a 24-h dietary recall and survey questions. For 7- to 12-mo-olds, an adapted Complementary Feeding Utility Index (CFUI) was used, and for 13- and 24-mo-olds, the Healthy Eating Index-2015 (HEI-2015) was used. Descriptive statistics were calculated for CFUI and HEI-2015 scores. Results: For 7- to 12-mo-olds, the CFUI score (mean ± SE) was 0.56 ± 0.003 (range: 0.34-0.90, maximum possible 1.0). Most children met CFUI standards for exposure to iron-rich cereal (86.7%), and low exposure to energy-dense nutrient-poor foods (72.2%) and teas/broths (67.5%). Conversely, at 7-12 mo of age, exposure was low for vegetables (7.0%), fruits (14.4%), any sugary drinks (14.0%), and 12-mo breastfeeding duration (23.8%). At 13 and 24 mo of age, the HEI-2015 total score (maximum possible 100), on average, was 64.0. At both 13 and 24 mo of age, participants achieved, on average, maximal HEI-2015 component scores for total and whole fruits and dairy; however, scores for total vegetables, greens and beans, whole grains, seafood and plant proteins, fatty acids, and saturated fats were relatively low. Scores for refined grains, sodium, and added sugar were lower at 24 than at 13 mo of age, representing higher consumption, on average, over time. Conclusions: Although findings demonstrate that young children are doing well on some dietary components, there is room for improvement, especially as children age. Findings may be used to inform the Pregnancy and Birth to 24-mo (P/B-24) Project. This trial was registered at clinicaltrials.gov as NCT02031978.

Is urban-rural location associated with weight status in school children? An examination of 42 small and rural Californian counties.

INTRODUCTON: Studies have identified geographic variation in overweight and obesity rates among children, with higher rates of overweight and obesity often found among children living in rural compared to urban areas. A small number of studies have explored differences in overweight and obesity based on more nuanced gradations along the urban-rural continuum. The purpose of the present study was to identify differences in overweight and obesity based on gradations along the urban-rural continuum among children in 42 Californian counties with populations less than 500 000. METHODS: An observational study was conducted using FITNESSGRAM data collected from 5th, 7th and 9th grade students in public schools in California during 2010-2011. The FITNESSGRAM dataset was merged with the 2011 Public Elementary/Secondary School Universe Survey Data from the National Center for Educational Statistics Common Core of Data, which includes an 'urban-centric locale' code for each school, consisting of four broad classifications - city, suburb, town, and rural - each of which is further broken down into three subcategories. Multivariate analyses using a general linear model were conducted to compare differences in body mass index (BMI) between geographic regions of schools (city, suburb, town and rural) as well as 11 urban-centric locale code subcategories; none of the schools were located in large cities. The percentage of students who were overweight and/or obese was compared by grade level, gender, and race/ethnicity across geographic regions using multivariate logistic regression models. Analyses were adjusted for student age, grade, gender, race/ethnicity (African-American, Asian, Hispanic, Indian/Alaskan, White, two or more races or unknown), eligibility for free or reduced price meals, and clustering of students by school. When a stratified analysis was done, the variable of stratification (ie grade, gender, race/ethnicity) was not included among the covariates. When significant differences in BMI or prevalence of overweight or obesity were found between geographic regions, Tukey's method was applied to adjust for multiple comparisons at a 5% procedure-wise error rate. A p-value at or less than 0.05 was used to indicate statistical significance. RESULTS: Students in suburban schools had significantly lower mean BMI and lower prevalence of overweight than students in other geographic areas (p<0.0001). Among 5th and 7th grade students, prevalence of obesity (but not overweight) varied by urban-rural status (p<0.0001, p=0.01, respectively), with 7th grade students in suburbs having lower rates of obesity than those in towns. Among 9th grade students, prevalence of overweight (but not obesity) varied by urban-rural status (p=0.02). Among females, prevalence of overweight and obesity varied (p=0.006, p<0.0001, respectively), with suburbs having lower rates than cities and towns. Among males, prevalence of obesity varied (p<0.0001), with suburbs having lower rates. Among whites, there were differences in prevalence of overweight and obesity by urban-rural status (p=0.01, p <0.0001, respectively). Among Hispanics, the prevalence of obesity varied by urban-rural status (p=0.001). Large suburban areas had the lowest rates of obesity compared to all other subcategories. CONCLUSIONS: Students attending schools in suburban, especially larger suburban, areas appear to have lower prevalence of obesity than their peers at schools in other geographic areas. Further research is needed to understand the factors associated with differences in weight status between urban, suburban, town and rural areas.

Sun-Exposed Skin Color Is Associated with Changes in Serum 25-Hydroxyvitamin D in Racially/Ethnically Diverse Children.

BACKGROUND: UVB light from the sun increases serum 25-hydroxyvitamin D [25(OH)D] concentration, but this relation may depend on skin pigmentation among different racial/ethnic groups. OBJECTIVE: We used quantitative measures of exposed (facultative) and unexposed (constitutive) skin color to examine relations between serum 25(OH)D concentration, tanning, race/ethnicity, and constitutive skin color over the summer, following winter vitamin D supplementation. METHODS: The subjects (n= 426, mean age 11.7 ± 1.4 y, 51% female) were racially/ethnically diverse schoolchildren (57% non-white/Caucasian) enrolled in a 6-mo vitamin D supplementation trial (October-December to April-June). In this secondary analysis, measures of serum 25(OH)D concentration and skin color, with the use of reflectance colorimetry, were taken over a 6-mo period after supplementation, from pre-summer (April-June) to post-summer (September-December). Multiple linear regression was used to evaluate longitudinal relations. RESULTS: Following supplementation, mean serum 25(OH)D concentration was 29.3 ± 9.5 ng/mL but fell to 25.6 ± 7.9 ng/mL (P< 0.0001) by the end of summer. The decrease in white/Caucasian children was less than in black/African American children (P< 0.01) and tended to be less than in Hispanic/Latino, Asian, and multiracial/other children (P= 0.19-0.50) despite similar changes in sun-exposed skin color among all groups. Tanning was significantly associated with post-summer serum 25(OH)D concentration (ß = -0.15,P< 0.0001), as was race/ethnicity (P= 0.0002), but the later association disappeared after adjusting for constitutive skin color. CONCLUSIONS: Tanning significantly contributed to serum 25(OH)D concentration over the summer, independent of race/ethnicity, but was not sufficient to maintain serum 25(OH)D concentration attained with supplementation. Much of the variation in serum 25(OH)D concentration between racial/ethnic groups may be explained by skin color. This trial was registered atclinicaltrials.govasNCT01537809.

Evaluating the Association of the Increase in the WIC Cash Value Benefit on the Diversity of MyPlate Fruits and Vegetables Redeemed and Consumed By Children in Low-Income Households.

Background: Fruits and vegetables (FV) are a critical source of nutrients, yet children in the United States are not meeting the Dietary Guidelines for Americans (DGA). The monthly FV cash value benefit (CVB) included in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)'s food package to support child FV intake (FVI) received a substantial increase for economic relief during the COVID-19 pandemic. Objectives: To evaluate how an expansion of the monthly WIC CVB to purchase FV for WIC children ages 1-4 y is associated with diversity in FV redeemed, and how changes in redeemed FV are related to FVI. Methods: Caregivers representing 1463 WIC-participating children recruited from Los Angeles County, California, completed surveys during the CVB augmentation (T1: CVB = $9/mo; T2 = $35/mo; T3 = $24/mo). Redeemed price look-up codes (PLUs), corresponding to a food item, were assigned to its corresponding MyPlate FV group. Multivariable generalized estimating equation regression models assessed changes in amount and diversity of FV redemption across MyPlate groups and associations between changes in FV diversity and changes in FVI. Results: Slightly over half of all households were food insecure (55%), half of the children were female (52%), and most were Hispanic (78%). Compared with T1, significant increases in the number of PLUs and dollars redeemed were observed in most MyPlate FV groups. From T1 to T2, significant increases in diversity scores were observed for total fruit (ß: 1.6 pts; 95% confidence interval [CI]: 1.4, 1.7), total vegetable (ß: 3.6 pts; 95%CI: 3.4, 3.9), and total FV (ß:7.8 pts; 95%CI: 7.4, 8.2). Similarly, increases in diversity score were observed at T3 compared with T1. Changes in FV diversity redeemed were not associated with changes in FVI. Conclusions: During the CVB augmentation, WIC participants redeemed a greater amount and variety of FV according to DGA MyPlate recommendations, supporting its permanent increase.

Associations between three school-based measures of health: is BMI enough?

School-based body mass index (BMI) notification programs are often used to raise parental awareness of childhood overweight and obesity, but how BMI results are associated with physical fitness and diet is less clear. This study examined the relationship between BMI, fitness, and diet quality in a diverse sample of urban schoolchildren (n = 122) utilizing a school-based cardiorespiratory fitness test and a food frequency questionnaire. Fifty-two percent of children were overweight/obese. Fit children were more likely to be normal weight than unfit children (p < .001). Weight status was not associated with adherence to any specific dietary guidelines; however, greater overall adherence to the recommendations was associated with normal weight (p < .05). These findings suggest a potential benefit may be gained by combining BMI reports with results of in-school fitness testing and basic information on how children's diets compare to recommendations.

Increased WIC Benefits for Fruits and Vegetables Increases Food Security and Satisfaction Among California Households with Young Children.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a critical source of nutrition support for young children in low-income families, providing access to healthy foods and a cash value benefit (CVB) for the purchase of fruits and vegetables (FV). In 2021, the WIC CVB increased substantially for women and children aged 1 to 5 years. OBJECTIVE: To investigate whether or not the increased WIC CVB for purchasing FV was associated with greater redemption of the FV benefit, satisfaction, household food security, and child FV intake. DESIGN: Longitudinal study of WIC participants receiving WIC benefits from May 2021 through May 2022. Through May 2021, the WIC CVB for children aged 1 to 4 years was $9/month. The value increased to $35/month from June through September 2021, and changed to $24/month starting October 2021. PARTICIPANTS AND SETTING: WIC participants from seven WIC sites in California with one or more child aged 1 to 4 years during May 2021 and one or more follow-up surveys during September 2021 or May 2022 (N = 1,770). MAIN OUTCOMES AND MEASURES: CVB redemption (in US dollars), satisfaction with the amount (prevalence), household food security (prevalence), and child FV intake (cups per day). STATISTICAL ANALYSES: Associations of increased CVB issuance following the June 2021 CVB augmentation with child FV intake and CVB redemption were assessed using mixed effects regression, and associations with satisfaction and household food security were assessed using modified Poisson regression. RESULTS: The increased CVB was associated with significantly greater redemption and satisfaction. At the second follow-up (May 2022), household food security increased by 10% (95% CI 7% to 12%); total FV intake decreased by 0.03 c/day (95% CI -0.06 to -0.01) in the overall sample, but increased by 0.23 c/day (95% CI 0.17 to 0.29) among children with the lowest baseline FV intake. CONCLUSIONS: This study documented benefits of augmentation to the CVB for children. WIC policy augmenting the value of WIC food packages to increase access to FV had the intended effects, lending support to making the increased FV benefit permanent.

Increased WIC Cash Value Benefit is Associated with Greater Amount and Diversity of Redeemed Fruits and Vegetables among Participating Households.

Background: Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages for children ages 1 to 4 y include a cash value benefit (CVB) redeemable for fruits and vegetables (FVs) with participating vendors. The CVB value was increased beginning in June 2021. Objectives: This study evaluated associations of the augmented CVB with the amount and diversity of redeemed FVs. Methods: Price look-up codes (PLUs) in redemption data determined outcomes including any redemption (any, none), amount redeemed (United States dollars [USD]/mo), and percent of total CVB redemption (percent) in 54 FV commodity groups among a cohort of 1770 WIC-participating children in Southern California. Outcomes across all commodity groups for fresh fruits, fresh vegetables, and all FVs were evaluated including dollar amount redeemed, percentage of redemption, and diversity of produce redeemed (variety and balance among items redeemed). Comparisons were made between augmented CVB periods (35 USD/mo in June-September 2021, 24 USD/mo October 2021-June 2022) and the preaugment period (9 USD/mo in June 2020-May 2021). Associations were tested in multivariable generalized estimating equation Poisson (any redemption) and linear (amount, percent, diversity) regression models. Results: The augmented CVB was associated with higher any redemption prevalence and amount redeemed for 53 of 54 commodity groups at both 35 USD/mo and 24 USD/mo compared with 9 USD/mo. Redemption diversity increased for both fruits, vegetables, and all produce during both augment periods, and modestly greater increases in redeemed fruits relative to vegetables were observed at 35 USD/mo. The most commonly redeemed vegetables were tomatoes, onions, cucumbers, peppers, and avocados and the most commonly redeemed fruits were bananas, apples, grapes, limes, and melons. Conclusions: The augmented CVB was associated with greater redeemed FV amount and greater redeemed FV diversity. Data on FV intake diversity among WIC-participating children are needed to understand dietary impacts of the CVB increase.

Racial and Ethnic Comparisons in Satisfaction with Services Provided by the Special Supplemental Nutrition Program for Women, Infants, and Children in California.

Understanding satisfaction of nutrition education and other services provided in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is needed to ensure the program is responsive to the needs of diverse populations. This study examined the variation of WIC participants' perceptions and satisfaction with WIC nutrition education and services by race, ethnicity, and language preference. Phone surveys were conducted in 2019 with California WIC families with children aged 1−4 years. While most participants (86%) preferred one-on-one nutrition education, online/mobile apps were also favored (69%). The majority (89%) found nutrition education equally important to receiving the WIC food package. Racial/ethnic groups differed in which WIC service they primarily valued as 20% of non-Hispanic White people rated the food package as more important than nutrition education compared to 5% of Spanish- and 6% of English-speaking Hispanic people, respectively. More Spanish (91%) and English-speaking Hispanic people (87%) than non-Hispanic white (79%) or Black people (74%) changed a behavior because of something they learned at WIC (p < 0.001). Spanish-speaking Hispanic people (90%) had the highest satisfaction with WIC nutrition education. Preferential differences among participants suggest that providing flexible options may improve program satisfaction and emphasizes the need for future studies to examine WIC services by race and ethnicity.

Energy-Adjusted Dietary Inflammatory Index and Diabetes Risk in Postmenopausal Hispanic Women.

BACKGROUND: Type 2 diabetes is a major public health concern in the United States and worldwide. The dietary inflammatory index (DII) and the energy-adjusted DII (E-DII) are tools that assess dietary inflammation. Previous evidence suggests that obesity can modify the association between inflammation and disease. OBJECTIVE: The aim of this study was to evaluate the association between the DII/E-DII and incident diabetes in self-identified Hispanic women from the Women's Health Initiative (WHI). The secondary aim was to evaluate whether obesity modifies the association between the DII/E-DII scores and incident diabetes. DESIGN: Participants were from the WHI Observational Study and the Clinical Trial Components (except women from the treatment arm in the Dietary Modification Trial) conducted among postmenopausal women in the United States. DII/E-DII scores were calculated from a self-administered food frequency questionnaire at baseline that included 122 food items, of which 12 are representative of Hispanic eating patterns. PARTICIPANTS/SETTINGS: Participants included 3,849 postmenopausal women who self-identified as Hispanic that were recruited for the WHI from 1993 to 1998 at 40 US clinical centers. MAIN OUTCOME MEASURES: The outcome was incident diabetes. STATISTICAL ANALYSIS PERFORMED: Cox regression models were used to assess the association between DII/E-DII and incident diabetes. Models were adjusted for age at baseline, lifestyle-related risk factors, known type 2 diabetes mellitus (T2DM) risk factors, and neighborhood socioeconomic status. Interaction was tested between the DII/E-DII scores and obesity. RESULTS: The incidence of diabetes was 13.1% after a median follow-up of 13 years. Higher E-DII scores were associated with a higher risk of incident diabetes (hazard ratio [HR], 1.09; 95% confidence interval [CI], 1.04-1.14). There was no interaction between E-DII scores and obesity (P = 0.73). CONCLUSIONS: Pro-inflammatory diets, as measured by higher E-DII scores, were associated with a higher risk of incident diabetes. Future research is needed for understanding how the inflammatory potential of diets can be decreased.

Vitamin D intake and serum vitamin D in ethnically diverse urban schoolchildren.

OBJECTIVE: Low serum vitamin D, which largely affects ethnic minorities, is associated with obesity and other chronic diseases. Little is known about racial/ethnic differences in intake, particularly in children, or if any differences are associated with differences in serum 25-hydroxyvitamin D (25(OH)D). The objective of the present study was to determine whether racial/ethnic differences in dietary vitamin D intake exist and whether they explain differences in 25(OH)D. DESIGN: Vitamin D intakes (Block Kids 2004 FFQ) and 25(OH)D were measured. Race/ethnicity was parent-reported (white (37·9 %), Hispanic (32·4 %), black (8·3 %), Asian (10·3 %), multi-racial/other (11·0 %)). Multivariable analyses were conducted to examine the associations among dietary vitamin D and race/ethnicity, as well as 25(OH)D, independent of BMI Z-score and other covariates. SETTING: Elementary/middle schools in Somerville, MA, USA, during January-April 2010. SUBJECTS: Schoolchildren (n 145) in 4th-8th grade. RESULTS: Only 2·1 % met the 2011 RDA (15 µg/d (600 IU/d)). Average dietary intake was 3.5 (sd 2.2) µg/d (140 (sd 89·0) IU/d). No racial/ethnic differences in intake were evident. Most (83·4 %) were 25(OH)D deficient (<20 ng/ml; 16·0 (sd 6·5) ng/ml). In ANOVA post hoc analyses, 25(OH)D levels were lower in Hispanics than whites (14·6 (sd 6·1) ng/ml v. 17·9 (sd 4·6) ng/ml; P < 0·01). Dietary vitamin D was associated with 25(OH)D overall (P < 0·05), but did not explain the racial/ethnic differences in 25(OH)D. CONCLUSIONS: Most children in this north-east US sample did not meet dietary recommendations for vitamin D and were vitamin D deficient. Dietary vitamin D did not explain the difference in 25(OH)D between Hispanic and white children. Further research is needed to determine if changes in dietary vitamin D by race/ethnicity can impact 25(OH)D levels.

Genetic admixture and cardiovascular disease risk in postmenopausal Hispanic women.

BACKGROUND: Hispanics are a heterogeneous population with differences in the prevalence of cardiovascular disease (CVD) and its related risk factors among ethnic sub-groups. This study evaluated the association of genetic admixture and CVD in self-identified Hispanic women from the Women's Health Initiative (WHI). METHODS: Data came from the WHI Observational Study and the Clinical Trial Components conducted among postmenopausal women. The CVD outcomes included coronary heart disease (CHD) and stroke. The proportions of European (EUR), sub-Saharan African (AFR), and Amerindian (AMI) admixture were estimated using 92 ancestry-informative markers. Cox regression models were used to assess the relationship between genetic admixture and CVD adjusting for age, lifestyle risk factors, known risk factors, and neighborhood socioeconomic status. RESULTS: Among 5195 participants EUR ancestry was associated with a lower CHD risk after adjusting for age (HR 0.41, p = 0.02), and in the fully adjusted model (HR 0.40, p = 0.03). AFR ancestry was associated with a higher CHD risk after adjusting for age (HR 2.91, p = 0.03), but it only showed a trend in in the fully adjusted model (HR 2.46, p = 0.10). AMI ancestry was not statistically significantly associated with CHD and none of the genetic admixture proportions were statistically significantly associated with stroke (p > 0.05). CONCLUSION: EUR ancestry was associated with a lower risk of CHD in Hispanic women. This highlights the need to account for genetic admixture in future CVD studies to consider different heritage groups to understand the role that genetic, neighborhood socioeconomic status, and environmental factors contribute to CVD health disparities in Hispanic women.

A Qualitative Examination of California WIC Participants' and Local Agency Directors' Experiences during the Coronavirus Disease 2019 Pandemic.

BACKGROUND: The US Department of Agriculture granted waivers to allow flexibility in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) operations during the coronavirus disease 2019 (COVID-19) pandemic; however, research examining the associations between waiver introduction and changes in perceptions, practices, and challenges of WIC participants' and agency directors' experiences is limited. OBJECTIVE: The objective of this study was to assess California WIC participants' and agency directors' perceptions and practices of remote WIC services during the COVID-19 pandemic. A secondary aim was to understand other COVID-19 challenges related to maintaining access to healthy foods by WIC participants. DESIGN: A qualitative study that included semistructured interviews was conducted between June 2020 and March 2021. PARTICIPANTS AND SETTING: One hundred eighty-two WIC participants with a child aged 0 to 5 years from three regions of California (Southern, Central, and Northern) and 22 local WIC agency directors across the state were interviewed. MAIN OUTCOME MEASURES: WIC participants' and agency directors' perceptions, practices, and other challenges during COVID-19. STATISTICAL ANALYSES PERFORMED: Interviews were recorded, transcribed, and analyzed using a grounded theory approach. RESULTS: Participants shared that they valued the information received from WIC and were very satisfied with remote WIC services. Participants reported that enrolling in WIC remotely was easier than coming in person. All waivers and changes to WIC operations, namely the physical presence, remote benefit issuance, and separation of duties waivers, and remote work and remote delivery of nutrition education, were largely viewed by WIC agency directors as options that should be continued postpandemic. Further, a majority (63%) of households reported experiencing food insecurity, and half of respondents received food from a food bank or pantry during the pandemic. CONCLUSIONS: Findings suggest WIC will attract and retain the most families by offering a hybrid model of services, incorporating both onsite services and remote options to work more efficiently and effectively.

Perceived Produce Availability and Child Fruit and Vegetable Intake: The Healthy Communities Study.

Children eat more fruits and vegetables when more are available at home, but less is known about how the neighborhood food environment relates to children's diet and weight outcomes. The goal of this study was to determine whether parental perception of the food environment (neighborhood and home) is associated with children's fruit and vegetable (F&V) intake and weight outcomes, and to assess differences by household food security status and household income. Cross-sectional data from the 2013-2015 U.S. Healthy Communities Study included 5138 children, aged 4 to 15 years old, from 130 U.S. communities. Neighborhood and home food environments were assessed with parent-reported, perceived F&V availability scores. Associations were tested with multi-level linear regression models. Parents' perception of produce availability was associated with household F&V availability ratings (ß = 0.09 points, p < 0.001). Household F&V availability was associated with child F&V intake (ß = 0.32 cups/day or 25.6 g/day, p < 0.001). A higher child F&V intake was associated with a lower child BMI z-score (ß = -0.05, p = 0.002). Weaker relationships were seen for children living in food insecure or low-income households. Optimizing neighborhood and home access to F&V may help children improve diet quality, but may not be as effective for children living in food insecure or low-income households.
