RESUMEN
Informed by the social ecological model, which asserts that health behaviors and beliefs are the result of multiple levels of influence, we examined factors related to parents' support for in-school COVID-19 mitigation strategies. Using data from a survey of 567 parents/caregivers of public elementary and middle school students in eight Maryland counties, we employed regression models to examine relationships between parent-, child-, family-, school-, and community-level factors and acceptability of mitigation strategies. Acceptance of COVID-19 mitigation strategies was positively correlated with child- and family-level factors, including child racial identity (parents of Black children were more accepting than those of White children, odds ratio [OR]: 2.5, 95% confidence interval [CI] = [1.5, 4.1]), parent receipt of the COVID-19 vaccine (OR: 2.4, 95% CI = [1.5, 3.7]), and parent Democrat or Independent political affiliation (compared with Republican affiliation, OR: 4.2, 95% CI = [2.6, 6.7]; OR: 2.2, 95%CI = [1.3, 3.8], respectively). Acceptance was also positively associated with parents' perceptions of their school's mitigation approach, including higher school mitigation score, indicating more intensive mitigation policies (OR: 1.1, 95% CI = [1.0, 1.1]), better school communication about COVID-19 (OR: 1.7, 95% CI = [1.4, 1.9]) and better school capacity to address COVID-19 (OR: 1.9, 95% CI = [1.5, 2.4]). Community-level factors were not associated with acceptance. Child- and parent-level factors identified suggest potential groups for messaging regarding mitigation strategies. School-level factors may play an important role in parents' acceptance of in-school mitigation strategies. Schools' capacity to address public health threats may offer an underappreciated and modifiable setting for disseminating and reinforcing public health guidance.
RESUMEN
A recent policy in the U.S. authorized monthly benefits from a nutrition assistance program - Supplemental Nutrition Assistance Program (SNAP) - to be used online to increase grocery access and promote healthy eating. This study examined online grocery attitudes and purchasing behaviors among low-income SNAP-eligible households with young children with and without online grocery experience. An explanatory sequential mixed methods design was used, including a survey informed by the theory of planned behavior (TPB) and focus groups conducted between November-March 2021. In the quantitative phase, 310 Maryland residents completed an online survey assessing TPB constructs (attitudes, social norms, perceived control), and food purchase frequency online and in-store. Subsequently, 42 participated in the qualitative phase. Differences in TPB constructs and food purchases were compared between families with and without online grocery experience. Online food selection and fees were a common obstacle to online grocery purchasing. Families who had purchased groceries online (57%) had more positive attitudes and perceived fewer barriers to online shopping than those who had not. Self-reported frequency of buying fresh produce (OR = 0.34, p < 0.001), meat and seafood (OR = 0.29, p < 0.001), and sweets (OR = 0.54, p = 0.005) were lower online than in-store. Families discussed mistrust of online hired shoppers and fewer impulse purchases online as reasons for less frequent purchases of produce and sweets, respectively. Successful scale-up of the U.S. policy must address barriers to healthier purchasing behaviors to effectively promote equitable food access, such as decreasing delivery fees and improving the online food selection.
RESUMEN
Despite the benefits of classroom physical activity breaks on student health and academic outcomes, more research is needed to understand what factors may be associated with classroom physical activity break implementation, to bolster buy-in from school stakeholders and increase implementation. This quantitative study examined frequency of classroom physical activity break implementation in relation to (1) objectively measured teachers' physical activity and sedentary behaviors, (2) confidence for leading classroom physical activity breaks, (3) social norms (perceptions of other teachers' classroom physical activity break implementation), and (4) teacher- and school-level demographics. In total, 153 classroom teachers in 20 elementary and middle schools completed a survey including classroom physical activity break frequency, confidence, and social norms, one item each, dichotomized (1 = "most/all the time" OR "agree/strongly agree"). Accelerometry assessed total activity and daytime sedentary behavior. Analyses included multilevel binary logistic regression. Teachers were 90% female, 68% White, and 55% in elementary schools. Odds of implementing classroom physical activity breaks were lower among middle school teachers, 14 times greater among those with greater confidence, and over 17 times greater when teachers perceived others frequently implementing classroom physical activity breaks. Teacher activity was not associated with classroom physical activity break implementation. Future interventions to increase classroom physical activity break implementation should focus on increasing teachers' confidence to lead classroom physical activity breaks and creating more buy-in from classroom teachers to enhance each school's culture of health. By enhancing teacher confidence and social norms for implementing classroom physical activity breaks, we may increase school-based physical activity opportunities.
RESUMEN
BACKGROUND: Few studies have evaluated teacher- and school-level characteristics associated with implementation of recommended physical activity (PA) promoting practices. The purpose of this study is to examine associations between teachers' PA practices and: [1] teacher-level factors, including their own PA, and [2] school-level factors. METHODS: This cross-sectional study examined time spent daily in light PA (LPA) and moderate-vigorous PA (MVPA) in association with 7 teacher PA practices among 288 classroom/special area teachers and teaching assistants in 20 urban, suburban and rural schools (recruited through a school wellness trial) in 4 districts. LPA and MVPA was assessed using 24-h ankle accelerometry (up to seven consecutive days). A sum score for teacher PA practices was assessed via survey (7 items; sum score range: 7-35; Cronbach's alpha = 0.73; higher scores indicate more PA promoting practices). Teacher-level factors included gender, race, self-reported height/weight, years teaching, and education. School-level factors included school type, free-and-reduced-price meal eligibility, student racial/ethnic composition, and urbanicity. Analyses included multilevel regression models, accounting for clustering within schools and adjusting for demographic covariates and school district. RESULTS: Teachers were 91% female, 63% elementary, 60% white, mean age 43.2 years (SD = 11.3), and 41% obese). Teachers wore accelerometers an average of 5.8 days, spent 399.6 min in LPA (SD = 85.0) per day, 24.1 min in MVPA (SD = 14.4) per day, and the mean teacher PA practices sum score was 22.4 (SD = 5.0). Every 15-min increase in MVPA was related to an increase in teacher PA practices sum score (coeff =1.07; SE = 0.28; p < 0.001). Female gender (versus males; coeff = - 1.95; SE = 0.92, p = 0.034), an obese weight status (versus non-obese; coeff = - 1.38; SE = 0.54, p = 0.010), and teaching in a middle school (versus elementary; coeff = - 3.86; SE = 0.54, p < 0.001) were associated with lower teacher PA practices scores. LPA was not associated with teacher PA promoting practices. CONCLUSIONS: Teachers with higher MVPA, but not higher LPA, and those without obesity were more likely to implement PA promoting practices that could positively impact their students' PA. Similar to prior studies, these practices were more commonly implemented in elementary schools and by male teachers. Future studies in schools should explore whether improvement of teacher health behaviors subsequently impacts student health behaviors.

BACKGROUND: Mothers of young children from low-income communities may be vulnerable to barriers associated with low physical activity. The purpose of this study was to examine associations between home environment factors and maternal physical activity among mothers of toddlers. METHODS: Mothers of toddlers (n = 200) recruited from low-income communities simultaneously wore an ankle-placed accelerometer and were given a personal digital assistant for ecological momentary assessment. Mothers received randomly prompted questions about their current environment, activity, and social setting several times a day over eight consecutive days. Data were analyzed using linear mixed-effects regression models with random intercepts; within-group and between-group relations between physical activity and environment factors were disaggregated. RESULTS: Within-group relations included higher physical activity counts for specific mothers with television off versus on (95% CI = 130.45, 199.17), children absent versus present (95% CI = 82.00, 3.43), engaging with a child versus not (95% CI = 52.66, 127.63), and outside versus inside location (95% CI = 277.74, 392.67). Between-group relations included higher physical activity on average when other adults were absent versus present (95% CI = - 282.63, - 46.95). Recruitment site (urban vs. semi-urban) significantly moderated the within-group relation between being outside versus inside and activity count (ß = - 243.12, 95% CI = - 358.74, - 127.47), and showed stronger relations among urban mothers (ß = 440.33, 95% CI = 358.41, 522.25), than semi-urban (ß = 190.37, 95% CI = 109.64, 271.11). Maternal body weight significantly moderated the within-group relation between being located outside versus inside the home and activity count (ß for interaction = - 188.67, 95% CI = - 308.95, - 68.39), with a stronger relation among mothers with normal weight (ß = 451.62, 95% CI = 345.51, 557.73), than mothers with overweight/obesity (ß = 271.95, 95% CI = 204.26, 339.64). CONCLUSIONS: This study highlights home environmental factors, including screen time, the presence of others (adults and children), and location (i.e., outside versus inside) that may relate to maternal physical activity behaviors. Understanding factors associated with physical activity could reduce physical activity disparities. Trial registry ClinicalTrials. NCT02615158, April 2006.

OBJECTIVE: The objective was to examine risk and protective factors associated with pre- to early-pandemic changes in risk of household food insecurity (FI). DESIGN: We re-enrolled families from two statewide studies (2017-2020) in an observational cohort (May-August 2020). Caregivers reported on risk of household FI, demographics, pandemic-related hardships, and participation in safety net programs (e.g. CARES stimulus payment, school meals). SETTING: Maryland, United States. PARTICIPANTS: Economically, geographically, and racially/ethnically diverse families with preschool to adolescent-age children. Eligibility included reported receipt or expected receipt of the CARES stimulus payment or a pandemic-related economic hardship (n=496). RESULTS: Prevalence of risk of FI was unchanged (pre-pandemic: 22%, early-pandemic: 25%, p=0.27). Risk of early-pandemic FI was elevated for non-Hispanic Black (aRR=2.1 [95% CI 1.1, 4.0]) and Other families (aRR=2.6 [1.3, 5.4]) and families earning ≤300% federal poverty level. Among pre-pandemic food secure families, decreased income, job loss, and reduced hours were associated with increased early-pandemic FI risk (aRR=2.1 [1.2, 3.6] to 2.5 [1.5, 4.1]); CARES stimulus payment (aRR=0.5 [0.3, 0.9]) and continued school meal participation (aRR=0.2 [0.1, 0.9]) were associated with decreased risk. Among families at risk of FI pre-pandemic, safety net program participation was not associated with early-pandemic FI risk. CONCLUSIONS: The CARES stimulus payment and continued school meal participation protected pre-pandemic food secure families from early-pandemic FI risk but did not protect families who were at risk of FI pre-pandemic. Mitigating pre-pandemic FI risk and providing stimulus payments and school meals may support children's health and reduce disparities in response to pandemics.
RESUMEN
Rapid weight gain increases risks of obesity and associated co-morbidities. The objective was to reduce the rate of body mass index (BMI) growth (BMI z score), relative to control. Secondary outcomes were toddler-mother physical activity, mealtime interactions and fruit/vegetable intake. The randomized three-arm, eight-session, 4-month trial, conducted 2009-2013, included two intervention arms (responsive parenting and maternal lifestyle) and an attention control (home safety). Baseline and 6- and 12-month follow-up evaluations included weight and length/height, ankle accelerometry, video-recorded mealtime interactions (Emotional Availability Scales) and 24-h diet recalls (Healthy Eating Index-2015 [HEI-2015]). Analyses used linear mixed-effects models with repeated measures comparing intervention versus control changes in BMI z score. We recruited 277 racially mixed (70% African American) toddler-mother dyads (mean ages 20.1 months and 27.3 years) from US WIC and primary care clinics and randomized them into intervention versus control; 31% toddlers and 73% mothers were overweight/obese. At follow-up, changes in the rate of toddler BMI z score and maternal BMI were non-significant. Maternal lifestyle group toddlers and mothers spent 24.43 and 11.01 more minutes in physical activity (95% confidence interval [CI]: 2.55, 46.32, and 95% CI: 1.48, 20.54, respectively). Fruit intake increased in both intervention groups. Hostile mealtime interactions increased in the maternal lifestyle group, and in supplementary analyses, mealtime interactions were significantly higher in the responsive parenting group than in the maternal lifestyles group, suggesting that toddler dietary interventions include responsive parenting. Intervention effects were stronger among older versus younger toddlers. Despite no impact on weight gain, additional research should examine integrated two-generation responsive parenting and maternal lifestyle interventions among toddler-mother dyads.

In 2019, the National School Lunch Program and School Breakfast Program served approximately 15 million breakfasts and 30 million lunches daily at low or no cost to students.Access to these meals has been disrupted as a result of long-term school closures related to the COVID-19 pandemic, potentially decreasing both student nutrient intake and household food security. By the week of March 23, 2020, all states had mandated statewide school closures as a result of the pandemic, and the number of weekly missed breakfasts and lunches served at school reached a peak of approximately 169.6 million; this weekly estimate remained steady through the final week of April.We highlight strategies that states and school districts are using to replace these missed meals, including a case study from Maryland and the US Department of Agriculture waivers that, in many cases, have introduced flexibility to allow for innovation. Also, we explore lessons learned from the pandemic with the goal of informing and strengthening future school nutrition policies for out-of-school time, such as over the summer.

OBJECTIVES: Toddlers are vulnerable to unintentional injuries. A safety intervention targeting low-income families of toddlers, was effective at improving home safety. The current study examined whether the effect varies by initial home safety problems. METHODS: 277 mother-toddler dyads recruited in the Mid-Atlantic region of the United States during 2007-2010 were randomized into safety promotion (n = 91) or attention-control groups (n = 186). Observers rated participants' homes with a 9-item safety problem checklist at baseline, and at 6- and 12-months follow-up. Initial home safety problems were categorized as multiple (≥ 4 problems) and none/few (< 4). Linear mixed models assessed the moderating effect with a three-way interaction (time, intervention, and initial safety problems). RESULTS: At 12 months, the intervention effect was stronger among families with multiple initial problems than no/few initial problems, with a reduction of 1.55 more problems among the families with multiple problems, compared to the families with no/few problems (b = - 1.55, SE = 0.62, p = 0.013). CONCLUSIONS: Interventions targeting families with multiple safety problems may be more effective than universal programming.

OBJECTIVE: To identify home environment factors associated with toddler dietary behaviours using ecological momentary assessment (EMA). DESIGN: Home environment and toddler's diet were assessed by mothers through EMA (random beeps over ≤8 d and a brief survey). Dietary outcomes were fruit/vegetable consumption, eating episode ('snack' v. 'meal') and sugar-sweetened beverage (SSB) consumption. Home environment factors included interacting with mother, eating alone/with others, eating in a high chair/chair at the table, watching television and movement/translocation. Multilevel logistic mixed-effects regression models assessed both within- (individual toddlers across time) and between- (toddlers-on-average) subject effects. SUBJECTS: Low-income mother-toddler dyads (n 277). SETTING: Urban and suburban Maryland, USA. RESULTS: EMA captured eating/drinking episodes for 249/277 (89·9 %) toddlers (883 eating episodes, 1586 drinking episodes). Toddlers-on-average were more likely (adjusted OR, P value) to eat fruit/vegetables when not moving around (0·43, P=0·043), eat with the television off (0·33, P<0·001) and eat in a high chair/chair (3·38, P<0·001); no within-subject effects were shown. For eating episodes, both toddlers-on-average and individual toddlers were more likely to eat snacks when not in a high chair/chair (0·13, P<0·001 and 0·06, P<0·001, respectively) and when eating alone (0·30, P<0·001 and 0·31, P<0·001, respectively). Also, individual toddlers were more likely to eat snacks when moving around (3·61, P<0·001). Toddlers-on-average were more likely to consume SSB when not in a high chair/chair (0·21, P=0·001), eating alone (0·38, P=0·047) or during a snacking episode (v. a meal: 3·96, P=0·012); no within-subject effects shown. CONCLUSIONS: Factors in the home environment are associated with dietary behaviours among toddlers. Understanding the interplay between the home environment and toddler diet can inform future paediatric dietary recommendations.

BACKGROUND: Toddler-aged children are vulnerable to unintentional injuries, especially those in low-income families. OBJECTIVE: To examine the effectiveness of an intervention grounded in social cognitive theory (SCT) on the reduction of home safety problems among low-income families with toddlers. METHODS: 277 low-income mother-toddler dyads were randomised into a safety promotion intervention (n=91) or an attention-control group (n=186). Mothers in the safety promotion intervention group received an eight-session, group-delivered safety intervention targeting fire prevention, fall prevention, poison control and car seat use, through health education, goal-setting and social support. Data collectors observed participants' homes and completed a nine-item checklist of home safety problems at study enrolment (baseline), 6 and 12â months after baseline. A total score was summed, with high scores indicating more problems. Linear mixed models compared the changes over time in home safety problems between intervention and control groups. RESULTS: The intent-to-treat analysis indicated that the safety promotion intervention group significantly reduced safety problems to a greater degree than the attention-control group at the 12-month follow-up (between-group difference in change over time ß=-0.54, 95% CI -0.05 to -1.03, p=0.035), with no significant differences at the 6-month follow-up. CONCLUSIONS: A safety promotion intervention built on principles of SCT has the potential to promote toddlers' home safety environment. Future studies should examine additional strategies to determine whether better penetration/compliance can produce more clinically important improvement in home safety practices.

INTRODUCTION: Worksite health promotion programs are emerging as an effective approach for addressing the adult obesity epidemic and improving the overall health of employees. METHODS: We conducted a scoping review to identify articles that described a physical activity component (eg, promoted increased physical or reduced sitting time) of a worksite health promotion intervention. Our search specified full-length articles published in English from January 2000 through July 2015. We used the Centers for Disease Control and Prevention's Worksite Health ScoreCard, a validated tool, as a framework to summarize information on organizational supports strategies (18 questions) and physical activity strategies (9 questions) implemented by worksite health promotion programs. We also determined whether or not the included studies reported significant (P < .05) improvements in physical activity. RESULTS: We identified 18 worksite health promotion programs; 11 produced significant improvements in physical activity. Incentives, health risk assessments, health promotion committees, leadership support, marketing, and subsidies or discounts for use of exercise facilities were the most effective organizational supports strategies cited, and physical activity seminars, classes, and workshops were the most effective physical activity strategies cited. CONCLUSION: The use of the Health ScoreCard allowed for a practical interpretation of our findings, which can inform next steps for the field. Future research should explore the relationships between components of worksite health promotion programs and their outcomes to further develop best practices that can improve worker health and promote physical activity.

INTRODUCTION: Few instruments assess key outcomes of school-based obesity interventions, including student perceptions of school environments and school-specific dietary intake patterns. This study describes development of PEA-PODS (Perceptions of the Environment and Patterns of Diet at School), a 2-part survey to measure these outcomes. METHODS: Part 1 (PEA) assessed student perceptions of policies, physical environment, and practices related to healthy eating and physical activity at school. Part 2 (PODS) assessed usual intake (ie, frequency, location obtained, and foods consumed) of breakfast and lunch. Foods consumed were presented by MyPlate categories (eg, Fruits, Grains). Students in grades 3, 6, and 9 participated in 2 phases: cognitive pre-testing (n = 10) and reliability/validation testing (n = 58). Both surveys were administered 1 week apart to assess test-retest reliability and 5-day food records validated PODS. Analyses included percent agreement (70% = acceptable), Pearson correlations, and Cronbach α. RESULTS: Cognitive pre-testing provided feedback on content, length, and age-appropriateness. Percent agreements were acceptable for test-retest reliability of PEA (71%-96%). The final version included 34 items with Likert-type responses in 4 subscales (α ≥0.78). For PODS, agreement for breakfast and lunch location was ≥75% for both reliability and validation. For foods consumed at breakfast, reliability agreement ranged from 74% to 93%, and validation agreement from 68% to 91%. For foods consumed at lunch, agreement ranges were 76% to 95% and 73% to 88%, respectively. CONCLUSION: Both parts of the instrument demonstrate acceptable reliability, and PODS demonstrates acceptable validity. This demonstrates appropriateness for assessing perceptions of the environment and usual dietary intake patterns for school-based obesity prevention initiatives.

BACKGROUND: Local wellness policies (LWPs) are mandated among school systems to enhance nutrition/physical activity opportunities in schools. Prior research notes disparities in LWP implementation. This study uses mixed methods to examine barriers/enablers to LWP implementation, comparing responses by student body income. METHOD: Schools ( n = 744, 24 systems) completed an LWP implementation barriers/enablers survey. Semistructured interviews ( n = 20 random subsample) described barriers/enablers. Responses were compared by majority of lower (≥50% free/reduced-price meals; lower income [LI]) versus higher income (HI) student body. RESULTS: In surveys, LI and HI schools identified common barriers (parents/families, federal/state regulations, students, time, funding) and enablers (school system, teachers, food service, physical education curriculum/resources, and staff). Interviews further elucidated how staffing and funding served as enablers for all schools, and provide context for how and why barriers differed by income: time, food service (HI schools), and parents/families (LI schools). CONCLUSIONS: Findings support commonalities in barriers and enablers among all schools, suggesting that regardless of economic context, schools would benefit from additional supports, such as physical education and nutrition education resources integrated into existing curricula, additional funding, and personnel time dedicated to wellness programming. LI schools may benefit from additional funding to support parent and community involvement.

OBJECTIVES: To examine changes in maternal-child health surrounding the April 2015 civil unrest in Baltimore, Maryland, following Freddie Gray's death while in police custody. METHODS: We conducted cross-sectional Children's HealthWatch surveys January 2014 through December 2015 in pediatric emergency departments and primary care clinics on maternal-child health and June 2015 through October 2015 on daily and community routines. We used trend analysis and piecewise logistic regression to examine effects of time, residential proximity moderation, and mediation analysis to assess proximity and maternal-child health relations via maternal concerns. RESULTS: Participants comprised 1095 mothers, 93% of whom were African American and 100% of whom had public or no insurance; 73% of participants' children were younger than 24 months. Following the unrest, prevalence of maternal depressive symptoms increased significantly in proximal, but not distal, neighborhoods (b = 0.41; 95% confidence interval [CI] = 0.03, 0.79; P = .03). Maternal concerns were elevated in proximal neighborhoods and associated with depressive symptoms; mediation through maternal concern was not significant. Five months after the unrest, depressive symptoms returned to previous levels. CONCLUSIONS: Civil unrest has an acute effect on maternal depressive symptoms in neighborhoods proximal to unrest. Public Health Implications. To mitigate depressive symptoms associated with civil unrest, maintain stability of community routines, screen for maternal depressive symptoms, and provide parent-child nurturing programs.

Schools with wellness teams are more likely to implement federally mandated Local Wellness Policies (LWPs, Local Education Agency-level policies for healthy eating/physical activity). Best practices have been developed for wellness teams based on minimal empirical evidence. The purpose of this study is to determine, among schools with wellness teams, associations between LWP implementation and six wellness team best practices (individually and as a sum score). An online survey targeting Maryland school wellness leaders/administrators (52.4% response rate, 2012-2013 school year) was administered that included LWP implementation (17-item scale: categorized as no, low, and high implementation) and six wellness team best practices. Analyses included multi-level multinomial logistic regression. Wellness teams were present in 311/707 (44.0%) schools, with no (19.6%), low (36.0%), and high (44.4%) LWP implementation. A sum score representing active wellness teams (mean=2.6) included: setting healthy eating/physical activity goals (66.9%), informing the public of LWP activities (71.4%), meeting ≥4times/year (45.8%), and having school staff (46.9%), parent (25.4%), or student (14.8%) representation. In adjusted models, goal setting, meeting ≥4times/year, and student representation were associated with high LWP implementation. For every one-unit increase in active wellness team sum score, schools were 41% more likely to be in high versus no implementation (Likelihood Ratio=1.41, 95% C.I.=1.13, 1.76). In conclusion, wellness teams meeting best practices are more likely to implement LWPs. Interventions should focus on the formation of wellness teams with recommended composition/activities. Study findings provide support for wellness team recommendations stemming from the 2016 Healthy, Hunger-Free Kids Act final rule.

OBJECTIVE: To determine whether living in a food swamp (≥4 corner stores within 0·40 km (0·25 miles) of home) or a food desert (generally, no supermarket or access to healthy foods) is associated with consumption of snacks/desserts or fruits/vegetables, and if neighbourhood-level socio-economic status (SES) confounds relationships. DESIGN: Cross-sectional. Assessments included diet (Youth/Adolescent FFQ, skewed dietary variables normalized) and measured height/weight (BMI-for-age percentiles/Z-scores calculated). A geographic information system geocoded home addresses and mapped food deserts/food swamps. Associations examined using multiple linear regression (MLR) models adjusting for age and BMI-for-age Z-score. SETTING: Baltimore City, MD, USA. SUBJECTS: Early adolescent girls (6th/7th grade, n 634; mean age 12·1 years; 90·7 % African American; 52·4 % overweight/obese), recruited from twenty-two urban, low-income schools. RESULTS: Girls' consumption of fruit, vegetables and snacks/desserts: 1·2, 1·7 and 3·4 servings/d, respectively. Girls' food environment: 10·4 % food desert only, 19·1 % food swamp only, 16·1 % both food desert/swamp and 54·4 % neither food desert/swamp. Average median neighbourhood-level household income: $US 35 298. In MLR models, girls living in both food deserts/swamps consumed additional servings of snacks/desserts v. girls living in neither (ß=0·13, P=0·029; 3·8 v. 3·2 servings/d). Specifically, girls living in food swamps consumed more snacks/desserts than girls who did not (ß=0·16, P=0·003; 3·7 v. 3·1 servings/d), with no confounding effect of neighbourhood-level SES. No associations were identified with food deserts or consumption of fruits/vegetables. CONCLUSIONS: Early adolescent girls living in food swamps consumed more snacks/desserts than girls not living in food swamps. Dietary interventions should consider the built environment/food access when addressing adolescent dietary behaviours.

BACKGROUND: To improve understanding of the pathophysiology of hypertension in adolescents and pave the way for risk stratification, studies have sought to determine the correlates of blood pressure (BP). Inconsistencies in dependent and independent variables have resulted in an elusive consensus. The aim of this report is to examine an inclusive array of correlates of BP, as a continuous (systolic and diastolic BP) and a dichotomous variable. METHODS: Subjects were a school-based sample of 730 urban, mostly African American, non-referred 6th and 7th grade girls. To find independent correlates of SBP/DBP, we used a stepwise model selection method based on the Schwarz Bayesian Information Criterion, enabling selection of a parsimonious model among highly correlated covariates. Candidate variables were: age, stature, heart rate, pubertal development, BMI, BMI z-score, waist circumference, waist-to-height ratio (WHtR), body surface area, fat mass (by bioelectrical impedance analysis), fat-free mass (FFM), percentage of body fat, and presence of overweight/obesity. RESULTS: The best-fitting models for DBP and SBP (considered separately) included fat-free mass, heart rate and, in the case of SBP, stature. The best-fitting model for high-normal/elevated blood pressure (H-N/EBP) included WHtR with no independent relation of any other variable. The prevalence of H-N/EBP tripled between a WHtR of 0.5 and 0.7. CONCLUSIONS: The easily obtained and calculated WHtR is the strongest correlate of elevated blood pressure among available variables and is a prime candidate for longitudinal studies of predictors of the development of hypertension.

BACKGROUND: Toddlerhood is an important age for physical activity (PA) promotion to prevent obesity and support a physically active lifestyle throughout childhood. Accurate assessment of PA is needed to determine trends/correlates of PA, time spent in sedentary, light, or moderate-vigorous PA (MVPA), and the effectiveness of PA promotion programs. Due to the limited availability of objective measures that have been validated and evaluated for feasibility in community studies, it is unclear which subgroups of toddlers are at the highest risk for inactivity. Using Actical ankle accelerometry, the objectives of this study are to develop valid thresholds, examine feasibility, and examine demographic/ anthropometric PA correlates of MVPA among toddlers from low-income families. METHODS: Two studies were conducted with toddlers (12-36 months). Laboratory Study (n = 24)- Two Actical accelerometers were placed on the ankle. PA was observed using the Child Activity Rating Scale (CARS, prescribed activities). Analyses included device equivalence reliability (correlation: activity counts of two Acticals), criterion-related validity (correlation: activity counts and CARS ratings), and sensitivity/specificity for thresholds. Community Study (n = 277, low-income mother-toddler dyads recruited)- An Actical was worn on the ankle for > 7 days (goal >5, 24-h days). Height/weight was measured. Mothers reported demographics. Analyses included frequencies (feasibility) and stepwise multiple linear regression (sMLR). RESULTS: Laboratory Study- Acticals demonstrated reliability (r = 0.980) and validity (r = 0.75). Thresholds demonstrated sensitivity (86 %) and specificity (88 %). Community Study- 86 % wore accelerometer, 69 % had valid data (mean = 5.2 days). Primary reasons for missing/invalid data: refusal (14 %) and wear-time ≤2 days (11 %). The MVPA threshold (>2200 cpm) yielded 54 min/day. In sMLR, MVPA was associated with age (older > younger, ß = 32.8, p < 0.001), gender (boys > girls, ß = -11.21, p = 0.032), maternal MVPA (ß = 0.44, p = 0.002) and recruitment location (suburban > urban, ß = 19.6, p < 0.001), or race (non-Black > Black, ß = 18.5, p = 0.001). No association with toddler weight status. CONCLUSIONS: Ankle accelerometry is a valid, reliable, and feasible method of assessing PA in community studies of toddlers from low-income families. Sub-populations of toddlers may be at increased risk for inactivity, including toddlers that are younger, female, Black, those with less active mothers, and those living in an urban location.

BACKGROUND: Recess provides an important opportunity for children to be physically active during weekdays. Updated, nationally representative, prevalence estimates of elementary school recess practices in the United States are needed. METHODS: Surveys were sent to a nationally representative sample of 1010 public elementary schools in the 2019-2020 school year. Results were compared by region (Northeast, Midwest, South, West), urbanicity, size, racial and ethnic composition, and socioeconomic status (percent eligible for free/reduced-priced meals). RESULTS: A total of 559 responses were obtained. About 87.9% of schools provided at least 20 minutes of daily recess and 26.6% had trained recess supervisors. Most schools did not allow students to voluntarily stay inside during recess (71.6%) and around half prohibited withholding recess for poor behavior (45.6%) or to complete schoolwork (49.5%). Several practices varied by region, and withholding recess was more prevalent among schools with lower student socioeconomic makeup. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Regular national surveillance of recess practices can inform policy needs and efforts to advance equitable access to recess. Quality and access should be considered when developing recess policies. CONCLUSIONS: Most United States elementary schools provide recess. However, regional and economic disparities exist. Promoting supportive practices for recess, particularly for schools serving lower-income communities, is necessary.
