Early Correlates of School Readiness Before and During the COVID-19 Pandemic Linking Health and School Data.

Importance: Many known correlates of kindergarten readiness are captured in developmental and social screenings in primary care; little is known about how primary care data predicts school readiness. Objective: To identify early Kindergarten Readiness Assessment (KRA) correlates by linking electronic health record (EHR) data with school district KRA data and to examine potential outcomes of the COVID-19 pandemic using KRA scores between 2018 and 2021. Design, Setting, and Participants: This was a retrospective cohort study linking a large primary care practice (PCP) with school assessment data. Linkage used patient name, date of birth, and address. The setting was an urban school district and PCP affiliated with an academic medical center. Students had a KRA score from fall of 2018, 2019, or 2021 (no 2020 KRA due to the COVID-19 pandemic) and at least 1 prior well-child visit at the PCP. Exposures: Exposures included year KRA administered, reported child race and ethnicity, child sex, interpreter for medical visits, child ever failed Ages & Stages Questionnaire (ASQ) 18 to 54 months, ever rarely read to, Medicaid status, food insecurity, housing insecurity, problems with benefits, and caregiver depressive symptoms. Main Outcomes and Measures: KRA score (continuous), with a possible range of 0 to 300 (passing score = 270). Results: A total of 3204 PCP patients (mean [SD] age, 67 [4] months; 1612 male [50.3%]; 2642 Black [82.5%]; 94 Hispanic [2.9%]; 244 White [7.6%]) were matched to their KRA score. Mean (SD) KRA scores were significantly lower in 2021 (mean [SD], 260.0 [13.0]; 214 of 998 [21.4%]) compared with 2019 (mean [SD], 262.7 [13.5]; 317 of 1114 [28.5%]) and 2018 (mean [SD], 263.5 [13.6]; 351 of 1092 [32.1%]), a pattern mirrored in the larger school district. In the linear regression final model (n = 2883), the following binary variables significantly lowered the child's KRA score (points lowered [95% CI]) below a mean passing score of 270.8: child ever failed ASQ after 18 months (-6.7; 95% CI, -7.7 to -5.6), Medicaid insured (-5.7; 95% CI, -9.0 to -2.3), Hispanic ethnicity (-3.8; 95% CI, -6.9 to -0.6), requires interpreter (-3.6; 95% CI, -7.1 to -0.1), 2021 year (-3.5; 95% CI, -4.7 to -2.3), male sex (-2.7; 95% CI, -3.7 to -1.8), ever rarely read to (-1.5; 95% CI, -2.6 to -0.4), and food insecurity (-1.2; 95% CI, -2.4 to -0.1). Race, caregiver depression, housing insecurity, and problems receiving benefits were not associated with KRA scores in final model. Conclusions and Relevance: Findings of this cohort study suggest a deleterious association of the COVID-19 pandemic with early learning and development. There may be potential for PCPs and school districts to collaborate to identify and mitigate risks much earlier.

Community-Led Interventions to Address Food Inequity.

Approximately 1 in 6 children in the United States, and 1 in 5 children in our local county (Hamilton County, Ohio), are food insecure. Here, we describe a novel community-academic partnership to address food inequity through distributed leadership and shared power with local neighborhood leaders. Using neighborhood-level data and community voice, 3 Cincinnati neighborhoods with high rates of poverty and food insecurity were selected as the primary intervention targets. Neighborhood leadership councils with community members representing each neighborhood were created. These councils requested intervention proposals and then decided which community designed interventions would receive grant funding. The academic partner provided grant funding distribution, quality improvement support, and data guidance and support for all partners, as well as community engagement support if desired by the community-led intervention leaders. In its first year (2021-2022), 9 interventions were funded, moving more than $250 000 into community-designed and community-led interventions to promote food security in 3 disadvantaged neighborhoods. Through leveraging community partnerships, these initiatives supplied 89 039 equivalent meals, including 56 244 pounds of produce, serving at least 3106 families in 3 neighborhoods in Cincinnati. Critical to the success of the initiatives were distributed leadership, shared power, word of mouth, and community engagement. The success of this type of community-academic partnership shows promise to address a wide variety of social and health challenges.

Feeding, television, and sleep behaviors at one year of age in a diverse sample.

Background: Healthy lifestyle behaviors that can prevent adverse health outcomes, including obesity, are formed in early childhood. This study describes feeding, television, and sleep behaviors among one-year-old infants and examines differences by sociodemographic factors. Methods: Caregivers of one-year-olds presenting for well care at two clinics, control sites for the Greenlight Study, were queried about feeding, television time, and sleep. Adjusted associations between sociodemographic factors and behaviors were performed by modified Poisson (binary), multinomial logistic (multi-category), or linear (continuous) regression models. Results: Of 235 one-year-olds enrolled, 81% had Medicaid, and 45% were Hispanic, 36% non-Hispanic Black, 19% non-Hispanic White. Common behaviors included 20% exclusive bottle use, 32% put to bed with bottle, mean daily juice intake of 4.1 ± 4.6 ounces, and active television time 45 ± 73 min. In adjusted analyses compared to Hispanic caregivers, non-Hispanic Black caregivers were less likely to report exclusive bottle use (odds ratio: 0.11, 95% confidence interval [CI] 0.03-0.39), reported 2.4 ounces more juice (95% CI 1.0-3.9), 124 min more passive television time (95% CI 60-188), and 37 min more active television time (95% CI 10-64). Increased caregiver education and higher income were associated with 0.4 (95% CI 0.13-0.66) and 0.3 (95% CI 0.06-0.55) more servings of fruits and vegetables per day, respectively. Conclusion: In a diverse sample of one-year-olds, caregivers reported few protective behaviors that reduce the risk for adverse health outcomes including obesity. Differences in behavior by race/ethnicity, income, and education can inform future interventions and policies. Future interventions should strive to create culturally effective messaging to address common adverse health behaviors.

STEP IN: Supporting Together Exercise and Play and Improving Nutrition; a Feasibility Study of Parent-Led Group Sessions and Fitness Trackers to Improve Family Healthy Lifestyle Behaviors in a Low-Income, Predominantly Black Population.

BACKGROUND: Pediatric obesity is prevalent and challenging to treat. Although family-centered behavioral management is the gold standard, many families face structural inequities to its access and efficacy. Identifying ways to manage pediatric obesity within primary care is needed. METHODS: This feasibility study included three sequential trials of peer-led group sessions occurring biweekly or monthly between 3/2016 and 2/2017. Parent-child dyads were recruited from a large academic primary care clinic via mailed invitations, prioritizing patients living in local zip codes of historical disinvestment. Eligible patients were 6 to 12 years with a body mass index ≥85th percentile, with parent and child interest in making healthy lifestyle changes, and English speaking. RESULTS: 27 dyads participated, 77% were non-Hispanic Black. Retention and attendance rates were highest in the initial four-session biweekly pilot (100%, 0 dropouts), high in the full six-session biweekly cohort (83%, 1 dropout), and moderate in the monthly cohort (62.7%, 4 dropouts). Families reported high satisfaction with the sessions (4.75/5). Qualitative comments suggested social connections had motivated behavior change in some families. CONCLUSION: Parent-led group sessions for pediatric weight management show promise in engaging families. A future large trial is needed to assess behavior change and anthropometric outcomes.

Characteristics Associated with Successful Weight Management in Youth with Obesity.

OBJECTIVE: To identify the medical, demographic, and behavioral factors associated with a reduction of body mass index percent of the 95th percentile (BMIp95) after 1 year for patients receiving care at a tertiary care obesity management clinic. STUDY DESIGN: A retrospective review of data from first and 12 ± 3-month follow-up visits of subjects aged 8-17 years with obesity. Data included anthropometrics, demographics, medical/psychological history, reported diet patterns, and participation in moderate/vigorous physical activity. After analyzing factors associated with 1-year follow-up, we used a forward conditional logistic regression model, controlling for subject's sex, to examine associations with a BMIp95 ≥5-point decrease at 1 year. RESULTS: Of 769 subjects, 184 (23.9%) had 1-year follow-up. Boys more often had follow-up (28.4% vs girls, 19.1%; P = .003). The follow-up sample was 62.0% male, 65.8% Hispanic, and 77.7% with public insurance; 33.2% achieved a ≥5-point decrease in BMIp95. In regression results, the ≥5-point decrease group was more likely to have completed an initial visit in April-September (OR 2.0, 95% CI 1.1-3.9); have increased physical activity by 1-2 d/wk (OR 3.4, 95% CI 1.4-7.8) or increased physical activity by ≥ 3 d/wk at 1 year (OR 2.7, 95% CI 1.1-6.3); and less likely to have been depressed at presentation (OR 0.4, 95% CI 0.2-0.9). Demographic and dietary factors were not significantly associated with BMIp95 group status. CONCLUSIONS: Strategies improving follow-up rates, addressing mental health concerns, and promoting year-round physical activity are needed to increase the effectiveness of obesity management clinics.

ER Stress Inhibits Liver Fatty Acid Oxidation while Unmitigated Stress Leads to Anorexia-Induced Lipolysis and Both Liver and Kidney Steatosis.

The unfolded protein response (UPR), induced by endoplasmic reticulum (ER) stress, regulates the expression of factors that restore protein folding homeostasis. However, in the liver and kidney, ER stress also leads to lipid accumulation, accompanied at least in the liver by transcriptional suppression of metabolic genes. The mechanisms of this accumulation, including which pathways contribute to the phenotype in each organ, are unclear. We combined gene expression profiling, biochemical assays, and untargeted lipidomics to understand the basis of stress-dependent lipid accumulation, taking advantage of enhanced hepatic and renal steatosis in mice lacking the ER stress sensor ATF6α. We found that impaired fatty acid oxidation contributed to the early development of steatosis in the liver but not the kidney, while anorexia-induced lipolysis promoted late triglyceride and free fatty acid accumulation in both organs. These findings provide evidence for both direct and indirect regulation of peripheral metabolism by ER stress.

Central serotonergic neurons activate and recruit thermogenic brown and beige fat and regulate glucose and lipid homeostasis.

Thermogenic brown and beige adipocytes convert chemical energy to heat by metabolizing glucose and lipids. Serotonin (5-HT) neurons in the CNS are essential for thermoregulation and accordingly may control metabolic activity of thermogenic fat. To test this, we generated mice in which the human diphtheria toxin receptor (DTR) was selectively expressed in central 5-HT neurons. Treatment with diphtheria toxin (DT) eliminated 5-HT neurons and caused loss of thermoregulation, brown adipose tissue (BAT) steatosis, and a >50% decrease in uncoupling protein 1 (Ucp1) expression in BAT and inguinal white adipose tissue (WAT). In parallel, blood glucose increased 3.5-fold, free fatty acids 13.4-fold, and triglycerides 6.5-fold. Similar BAT and beige fat defects occurred in Lmx1b(f/f)ePet1(Cre) mice in which 5-HT neurons fail to develop in utero. We conclude 5-HT neurons play a major role in regulating glucose and lipid homeostasis, in part through recruitment and metabolic activation of brown and beige adipocytes.

Sirtuin-1 is a nutrient-dependent modulator of inflammation.

Inflammation accompanies obesity and its comorbidities-type 2 diabetes, non-alcoholic fatty liver disease and atherosclerosis, among others-and may contribute to their pathogenesis. Yet the cellular machinery that links nutrient sensing to inflammation remains incompletely characterized. The protein deacetylase sirtuin-1 (SirT1) is activated by energy depletion and plays a critical role in the mammalian response to fasting. More recently it has been implicated in the repression of inflammation. SirT1 mRNA and protein expression are suppressed in obese rodent and human white adipose tissue, while experimental reduction of SirT1 in adipocytes and macrophages causes low-grade inflammation that mimics that observed in obesity. Thus suppression of SirT1 during overnutrition may be critical to the development of obesity-associated inflammation. This effect is attributable to multiple actions of SirT1, including direct deacetylation of NFκB and chromatin remodeling at inflammatory gene promoters. In this work, we report that SirT1 is also suppressed by diet-induced obesity in macrophages, which are key contributors to the ontogeny of metabolic inflammation. Thus, SirT1 may be a common mechanism by which cells sense nutrient status and modulate inflammatory signaling networks in accordance with organismal energy availability.
