SARS-CoV-2 seroprevalence rates of children seeking medical care in Louisiana during the state stay at home order.

Serologic testing of residual blood samples from 812 children from a hospital in New Orleans, LA, between March and May 2020, demonstrated a SARS-CoV-2 seroprevalence of 6.8% based on S and N protein IgG; Black and Hispanic children, and children living in zip codes with lower household incomes were over-represented.

The role of poverty status and obesity on school attendance in the United States.

PURPOSE: Several studies have shown that obesity influences school performance. Little is known about the joint effect of poverty and obesity associated with school attendance. METHODS: Data are from the National Survey of Children's Health (N = 93,151), a nationally representative sample of U.S. youth aged 10-17 years. Our dependent variable was ≥11 days of school days missed per year. Body mass index was classified as normal, overweight, and obese using age- and sex-specific criteria. Federal poverty level (FPL) was classified as <200%, 200%-399%, and ≥400% (high income). Covariates included gender, age, child's race or ethnicity, maternal physical and mental health, child's health, family composition, and household tobacco use. Logistic regression models and prevalence ratios were estimated, accounting for the complex survey design. RESULTS: The odds of missing ≥11 days of school among overweight youth was 1.5 times that of normal-weight youth (95% confidence interval (CI) = 1.22-1.85) and 1.7 (95% CI = 1.35-2.13) times among obese youth in fully adjusted models. In joint effects models, the probability of missing school was significantly greater for obese youth in both the <200% FPL group (prevalence ratio = 1.78, CI = 1.36-2.34) and the ≥400% FPL group (prevalence ratio = 2.88, CI = 1.91-4.35), when compared with their normal-weight, higher income peers. Predicted probabilities revealed sharper gradients for higher income youth. CONCLUSIONS: Obesity influences school absenteeism across all income categories. Nonetheless, there may be distinct reasons for missing school for lower and higher income youth, and the long-term consequences of school absences may also differ for these populations.
