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.

Longer Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Participation Duration Is Associated with Higher Diet Quality at Age 5 Years.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides supplemental healthy foods and nutrition education to children under age 5 y in low-income households. OBJECTIVES: We aimed to identify characteristics associated with duration of WIC participation and assess how participation duration relates to household food insecurity (HFI), child diet quality, and child weight status at age 60 mo. METHODS: This analysis of the WIC Infant and Toddler Feeding Practices Study-2, a prospective cohort of WIC-participating children enrolled in 2013, included children with complete baseline-60 mo data (n = 836). Outcomes assessed with WIC participation duration in multivariable regression were HFI (USDA 6-item Household Food Security Screener), child diet quality on a given day [Healthy Eating Index (HEI)-2015], and obesity (CDC BMI-for-age ≥95th percentile). RESULTS: Factors associated with longer WIC participation included male sex; lower household income; reported diet changes in response to WIC nutrition education; household Supplemental Nutrition Assistance Program participation; English-speaking Hispanic, Spanish-speaking Hispanic, and non-Hispanic other maternal race-ethnicity and language preference; an ever-married mother; lower maternal education; higher maternal age; earlier enrollment during pregnancy; and reporting a subsequent pregnancy. Longer WIC participation was associated with lower HFI odds (OR: 0.69; 95% CI: 0.51, 0.95), higher total HEI-2015 (ß: 0.73; 95% CI: 0.20, 1.25), and higher obesity odds (OR: 1.20; 95% CI: 1.05, 1.37) in multivariable-adjusted regression models. CONCLUSIONS: Longer WIC participation was associated with reduced HFI and higher diet quality, and unexpectedly with higher obesity odds, at 60 mo. Further research is needed to confirm and understand mechanisms underlying the unexpected associations identified with longer WIC participation (e.g., male sex, obesity). Groups with shorter participation durations may benefit from targeted WIC retention efforts to maximize nutrition security.

Restaurant kids' meal beverage offerings before and after implementation of healthy default beverage policy statewide in California compared with citywide in Wilmington, Delaware.

OBJECTIVE: In 2019, California and Wilmington, Delaware' implemented policies requiring healthier default beverages with restaurant kids' meals. The current study assessed restaurant beverage offerings and manager perceptions. DESIGN: Pre-post menu observations were conducted in California and Wilmington. Observations of cashiers/servers during orders were conducted pre-post implementation in California and post-implementation in Wilmington. Changes in California were compared using multilevel logistic regression and paired t tests. Post-implementation, managers were interviewed. SETTING: Inside and drive-through ordering venues in a sample of quick-service restaurants in low-income California communities and all restaurants in Wilmington subject to the policy, the month before and 7-12 months after policy implementation. PARTICIPANTS: Restaurant observations (California n 110; Wilmington n 14); managers (California n 75; Wilmington n 15). RESULTS: Pre-implementation, the most common kids' meal beverages on California menus were unflavoured milk and water (78·8 %, 52·0 %); in Wilmington, juice, milk and sugar-sweetened beverages were most common (81·8 %, 66·7 % and 46·2 %). Post-implementation, menus including only policy-consistent beverages significantly increased in California (9·7 % to 66·1 %, P < 0·0001), but remained constant in Wilmington (30·8 %). During orders, cashiers/servers offering only policy-consistent beverages significantly decreased post-implementation in California (5·0 % to 1·0 %, P = 0·002). Few managers (California 29·3 %; Wilmington 0 %) reported policy knowledge, although most expressed support. Most managers wanted additional information for customers and staff. CONCLUSIONS: While the proportion of menus offering only policy-consistent kids' meal default beverages increased in California, offerings did not change in Wilmington. In both jurisdictions, managers lacked policy knowledge, and few cashiers/servers offered only policy-consistent beverages. Additional efforts are needed to strengthen implementation of kids' meal beverage policies.

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.

Drinking Water in the United States: Implications of Water Safety, Access, and Consumption.

Recent water quality crises in the United States, and recognition of the health importance of drinking water in lieu of sugar-sweetened beverages, have raised interest in water safety, access, and consumption. This review uses a socioecological lens to examine these topics across the life course. We review water intakes in the United States relative to requirements, including variation by age and race/ethnicity. We describe US regulations that seek to ensure that drinking water is safe to consume for most Americans and discuss strategies to reduce drinking water exposure to lead, a high-profile regulated drinking water contaminant. We discuss programs, policies, and environmental interventions that foster effective drinking water access, a concept that encompasses key elements needed to improve water intake. We conclude with recommendations for research, policies, regulations, and practices needed to ensure optimal water intake by all in the United States and elsewhere.

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.

Development of an online curriculum for California early care and education providers on healthy beverages.

BACKGROUND: Children's consumption of sugar-sweetened beverages is associated with obesity, diabetes, and dental decay. California's Healthy Beverages in Child Care Act (AB 2084) requires all licensed child care centers and family child care homes to comply with healthy beverages standards, however many licensed providers in California are unaware of the law and few are fully compliant with the law's requirements. The aim of the current project is to describe the development of a self-paced online training on best practices and implementation of AB 2084 in English and Spanish for family child care home and child care center providers; and to evaluate the feasibility, defined as being accessible, acceptable, and satisfactory to providers, of this new online course. METHODS: The project was broken into two main stages: (1) development of the online course; and (2) evaluation of the final online course. The first stage was completed in five phases: (1) identify relevant course content and develop narration script; (2) conduct in-person focus groups with child care providers to review and edit the content; (3) adapt course content and translate for Spanish-speaking providers; (4) build the online course and resources; and (5) pilot online course and evaluate accessibility. The second stage, evaluation of the acceptability and satisfaction of the final course was rated on a Likert scale from 1 to 4; the evaluation was completed as part of a larger randomized control trial with 43 child care providers. The course features four key requirements of AB 2084 as the main sections of the course (milk, sweetened beverages, juice, and water), plus background information about beverages and children's health, special topics including caring for children with special needs, family engagement, written policies, and child engagement. RESULTS: The child care providers who completed the evaluation found the online training was easily understandable (median(Q1,Q3,IQR) = 4 (4,4,0)), included new information (3 (1, 3, 4)), provided useful resources (4(4,4,0)), and was rated with high overall satisfaction (3 (1, 3, 4)). CONCLUSION: Online training in English and Spanish designed for child care providers is a feasible medium to deliver important health messages to child care providers in an accessible, acceptable, and satisfactory manner.

Nutrition Provided to Infants in Licensed Childcare Centers and Homes: A Descriptive Study.

BACKGROUND: Infant nutrition can influence development, eating behaviors and obesity risk. Nearly half of infants in the U.S. are in non-parental care where they consume much of their daily nutrition. Because little is known about the quality of infant nutrition in childcare, the study objective was to characterize the foods and beverages provided to infants in childcare in California. METHODS: From a randomly selected sample of 2,400 licensed childcare in California, 736 responded to a 2016 survey; a subset of 297 cared for infants. Differences in 26 foods and 7 beverages provided between centers and homes, and by CACFP participation, were assessed using logistic regression models adjusted for CACFP participation and whether the site was a center or home, respectively. RESULTS: Several differences between centers and homes were identified. One the day prior to the survey, more centers than homes ever provided cow's milk (25.1% vs 13.0%, p = 0.02) and whole grains (76.7% vs 62.9%, p = 0.03), and fewer centers than homes provided frozen treats (1.4% vs 10.3%, p = 0.003). When comparing difference by CACFP participation, fewer CACFP than non-CACFP sites usually provided breastmilk (32.6% vs 54.2%, p = 0.0004) and ever provided cow's milk (14.2% vs 37.1%, p < 0.0001). On the day prior to the survey, more CACFP than non-CACFP provided vegetables (91.0% vs 80.8%, p = 0.02), fruit (centers only) (97.2% vs 80.8%, p = 0.0003), and infant cereals (86.0% vs 61.2%, p < 0.0001). Fewer CACFP than non-CACFP provided sweetened yogurt (14.8% vs 36.7%, p < 0.0001). CONCLUSIONS FOR PRACTICE: Childcare centers and CACFP participants tended to serve nutritious foods more than childcare homes and non-CACFP participants, respectively. Additional education and policies for childcare providers on appropriate foods and beverages for infants is recommended.

Effect of Removing Chocolate Milk on Milk and Nutrient Intake Among Urban Secondary School Students.

INTRODUCTION: Schools across the United States have removed sweetened, flavored milk from cafeterias to reduce students' sugar consumption and improve their health. However, evidence on the impact of the removal is limited. We examined the effect of a policy that removed chocolate milk from secondary schools on students' milk consumption and estimated milk-related nutrient intake. METHODS: We collected data on milk selection and consumption during 1 lunch period in 24 California public secondary schools pre-policy (N = 3,158 students in 2016) and post-policy (N = 2,966 students in 2018). Schools had a student population that was 38% Asian and 29% Latino, with 63% qualifying for free or reduced-price meals. We used linear mixed effects models to assess changes in milk selection and waste, and we estimated related changes in added sugars, calcium, protein, and vitamin D consumed from milk. RESULTS: The proportion of students selecting milk declined 13.6%, from 89.5% pre-policy to 75.9% post-policy (95% CI for difference, 10.8% tο 16.4%), but the proportion of milk wasted remained stable (37.1% vs 39.3%; 95% CI for difference, -0.2% to 4.6%). Although average per-student milk consumption declined by less than 1 ounce per student (from 4.8 oz to 3.8 oz; 95% CI for difference, -1.1 oz to -0.7 oz), we observed no significant reductions in average per-student intake of calcium, protein, or vitamin D from milk. Estimated added sugars from milk declined significantly, by 3.1 grams per student (95% CI, -3.2 g to -2.9 g). CONCLUSION: Removing chocolate milk modestly reduced student milk consumption without compromising average intake of key milk-related nutrients, and consumption of added sugars from milk declined significantly. Secondary schools should consider removing chocolate milk to support healthy beverage consumption.

Status of Beverages Served to Young Children in Child Care After Implementation of California Policy, 2012-2016.

INTRODUCTION: Since 2012, licensed California child care centers and homes, per state policy, are required to serve only unflavored low-fat or nonfat milk to children aged 2 years or older, no more than one serving of 100% juice daily, and no beverages with added sweeteners, and they are required to ensure that drinking water is readily accessible throughout the day. We evaluated adherence to the policy after 4 years in comparison to the adherence evaluation conducted shortly after the policy went into effect. METHODS: Licensed California child care sites were randomly selected in 2012 and 2016 and surveyed about beverage practices and provisions to children aged 1-5 years. We used logistic regression to analyze between-year differences for all sites combined and within-year differences by site type and participation in the federal Child and Adult Care Food Program (CACFP) in self-reported policy adherence and beverage provisions. RESULTS: Respondents in 2016 (n = 680), compared with those in 2012 (n = 435), were more adherent to California's 2010 Healthy Beverages in Child Care Act overall (45.1% vs 27.2%, P < .001) and with individual provisions for milk (65.0% vs 41.4%, P < .001), 100% juice (91.2% vs 81.5%, P < .001), and sugar-sweetened beverages (97.4% vs 93.4%, P = .006). In 2016, centers compared with homes (48.5% vs 28.0%, P = .001) and CACFP sites compared with non-CACFP sites (51.6% vs 27.9%, P < .001) were more adherent to AB2084 overall. DISCUSSION: Beverage policy adherence in California child care has improved since 2012 and is higher in CACFP sites and centers. Additional policy promotion and implementation support is encouraged for non-CACFP sites and homes. Other states should consider adopting such policies.

Association of Multisetting Community Programs and Policies With Child Body Mass Index: The Healthy Communities Study.

INTRODUCTION: Expert opinion suggests that efforts to address childhood obesity should seek to transform the environments in which children operate. The objective of this study was to describe the extent to which multisetting programs and policies interact with community and child predictors and are associated with child body mass index (BMI) in the 130 US communities participating in the Healthy Communities Study. METHODS: For 2 years beginning in fall 2013, we collected data through key informant interviews on community programs and policies related to healthy weight among children that occurred in the 10 years before the interview. We characterized community programs and policies by intensity of efforts and the number of settings in which a program or policy was implemented. Child height and weight were measured during household data collection. We used multilevel modeling to examine associations of community programs and policies in multiple settings and child and community predictors with BMI z scores of children. RESULTS: The mean number of settings in which community policies and programs were implemented was 7.3 per community. Of 130 communities, 31 (23.8%) implemented community programs and policies in multiple settings. Higher-intensity community programs and policies were associated with lower BMI in communities that used multiple settings but not in communities that implemented programs and policies in few settings. CONCLUSION: Efforts to prevent childhood obesity may be more effective when community programs and policies are both intensive and are implemented in multiple settings in which children live, learn, and play.

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.

Comparison of the NHANES dietary screener questionnaire to the Automated Self-Administered 24-Hour Recall for Children in the Healthy Communities Study.

BACKGROUND: A dietary screener questionnaire (DSQ) was used to assess dietary outcomes among children in the Healthy Communities Study (HCS), a study of the relationships between programs and policies to prevent child obesity and child diet, physical activity and weight outcomes. METHODS: To compare dietary intake estimates derived from the DSQ against those from the Automated Self-Administered 24-Hour Recalls for Children (ASA24-Kids) among children, a measurement error model, using structural equation modelling, was utilized to estimate slopes, deattenuated correlation coefficients, and attenuation factors by age and sex, ethnicity, and BMI status. PARTICIPANTS/SETTING: A randomly selected sub-sample of HCS participants aged 4-15 years in 130 communities throughout the U.S. who completed the DSQ and up to two ASA24-Kids recalls (n = 656;13% of HCS participants). RESULTS: For most nutrient/foods examined, the DSQ yielded larger mean intake estimates than the ASA24-Kids, and agreement between the two measures varied by food/nutrient, age and sex, ethnicity, and BMI category. Deattenuated correlation coefficients of 0.4 or greater were observed for added sugars from SSBs (0.54), fruits and vegetables (0.40), and dairy foods (0.50). Lower deattenuated correlation coefficients were seen for total added sugars (0.37), whole grains (0.34), and fiber (0.34). Attenuation factors were most severe for total added sugars intake among overweight children, and for several other dietary outcomes among children aged 9-11 years. CONCLUSIONS: The DSQ was found to be a tool with acceptable agreement with the ASA24-Kids for measuring multiple dietary outcomes of interest in the HCS, although there may be potential due to measurement error to underestimate results (bias towards the null). In future studies, measurement error modelling and regression calibration may be possible solutions to correct for bias due to measurement error in most food/nutrient intake estimates from the DSQ when used among children.

Excessive Gestational Weight Gain and Subsequent Maternal Obesity at Age 40: A Hypothetical Intervention.

OBJECTIVES: To model the hypothetical impact of preventing excessive gestational weight gain on midlife obesity and compare the estimated reduction with the US Healthy People 2020 goal of a 10% reduction of obesity prevalence in adults. METHODS: We analyzed 3917 women with 1 to 3 pregnancies in the prospective US National Longitudinal Survey of Youth, from 1979 to 2012. We compared the estimated obesity prevalence between 2 scenarios: gestational weight gain as reported and under the scenario of a hypothetical intervention that all women with excessive gestational weight gain instead gained as recommended by the Institute of Medicine (2009). RESULTS: A hypothetical intervention was associated with a significantly reduced estimated prevalence of obesity for first (3.3 percentage points; 95% confidence interval [CI] = 1.0, 5.6) and second (3.0 percentage points; 95% CI = 0.7, 5.2) births, and twice as high in Black as in White mothers, but not significant in Hispanics. The population attributable fraction was 10.7% (95% CI = 3.3%, 18.1%) in first and 9.3% (95% CI = 2.2%, 16.5%) in second births. CONCLUSIONS: Development of effective weight-management interventions for childbearing women could lead to meaningful reductions in long-term obesity.

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.

Child experience of food insecurity is associated with child diet and physical activity.

BACKGROUND: Food insecurity is associated with deficits in child development and health, but little is known about how children's specific food-insecurity experiences play out through nutritional and non-nutritional pathways that may compromise well-being. OBJECTIVE: This study used child self-reports of food insecurity to examine the types of food-insecurity experiences that were most prevalent and the relations between child food insecurity (CFI), child diet, and child physical activity (PA). METHODS: A total of 3605 fourth- and fifth-grade children whose schools participated in the Network for a Healthy California-Children's PowerPlay! campaign completed 24-h diary-assisted recalls and surveys including items from the Child Food Security Assessment and questions about PA. Data were analyzed by using regression and logistic regression models. RESULTS: CFI was present in 60% of the children and included experiences of cognitive, emotional, and physical awareness of food insecurity. Greater levels of CFI were associated with higher consumption of energy, fat, sugar, and fiber and a diet lower in vegetables. For instance, a child at the highest level of CFI, on average, consumed ∼494 kJ/d (118 kcal), 8 g/d of sugar, and 4 g/d of fat more than a food-secure child. Higher CFI was associated with a marginally significant difference (P = 0.06) in minutes of PA (17 min/d less for children at the highest level of CFI vs. those who were food secure) and with significantly greater perceived barriers to PA. CONCLUSIONS: CFI is a troublingly frequent, multidomain experience that influences children's well-being through both nutritional (dietary) and non-nutritional (e.g., PA) pathways. CFI may lead to poor-quality diet and less PA and their developmental consequences. Practitioners should consider CFI when assessing child health and well-being and can do so by asking children directly about their CFI experiences.
