Ratio of Infections to COVID-19 Cases and Hospitalizations in the United States based on SARS-CoV-2 Seroprevalence Data, September 2021-February 2022.

Background: Understanding the risk of hospitalization from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can guide effective public health interventions and severity assessments. This study calculated infection-hospitalization ratios (IHRs) and infection-case ratios (ICRs) to understand the relationship between SARS-CoV-2 infections, cases, and hospitalizations among different age groups during periods of Delta and Omicron variant predominance.

Methods: After calculating antinucleocapsid SARS-CoV-2 antibody seroprevalence using residual commercial laboratory serum specimens, 2 ratios were computed: (1) IHRs using coronavirus disease 2019 hospitalization data and (2) ICRs using Centers for Disease Control and Prevention surveillance data.

What influences demand for cigars among African American adult cigar smokers? Results from a hypothetical purchase task.

African Americans (AA) have historically been targeted by the tobacco industry and have the highest rates of current cigar use among racial/ethnic groups in the U.S. Yet, there is limited evidence on other factors influencing cigar use.

Pregnancy-related weight among immigrant and US-born mothers: The role of nativity, maternal duration of residence, and age at arrival.

Objectives: The goals of this study were to examine the associations between nativity and pregnancy-related weight and to assess the associations between maternal duration of residence and age at arrival in the United States on pregnancy-related weight among immigrants.

Methods: Using logistic regression and data from the Early Childhood Longitudinal Study-Birth Cohort, we assessed differences in preconception weight and gestational weight gain between US-born and immigrant women (N = 7000). We then analyzed differences in both outcomes by duration of residence among immigrants (n = 1850) and examined whether the identified relationships varied by age at arrival in the United States.

Pregnancy-Related Weight and Postpartum Depressive Symptoms: Do the Relationships Differ by Race/Ethnicity?

There are significant racial/ethnic disparities in the prevalence of postpartum depression. Prior research in the general population suggests that weight status is related to depression and that this relationship varies by race/ethnicity. However, few studies have investigated whether race/ethnicity moderates the relationship between pregnancy-related weight and postpartum depressive symptoms (PPDS).
