Objectives: Women experiencing homelessness have higher rates of unintended pregnancy than stably housed women and may benefit from reproductive interconception care. How reproductive interconception care differs between women who did and did not experience perinatal homelessness is not known. We estimated prevalence ratios of reproductive interconception behaviors among US women experiencing homelessness during the perinatal period.

Methods: We used data from the 2016-2019 Pregnancy Risk Assessment Monitoring System to calculate the prevalence of 5 reproductive interconception care outcomes: attending a maternal postpartum checkup, participating in a conversation with a health care provider about birth intervals, receiving family planning counseling, obtaining a prescription for short-acting contraception, and having a long-acting reversible contraceptive inserted. We used complex survey weights, stratified by perinatal homelessness, and converted adjusted logistic regression odds ratios between housing status and outcome variables to adjusted prevalence ratios (aPRs) and 95% CIs.

Results: Among participants, approximately 2.4% (weighted percentage; unweighted 2953 of 100 706) experienced homelessness sometime in the 12 months before their children were born; the majority were non-Hispanic (83.2%) and White (69.4%), were not married (82.2%), and had public health insurance (56.8%). Perinatal homelessness was significantly associated with a lower prevalence of attending a postpartum maternal visit (aPR = 0.90; 95% CI, 0.87-0.94) and a higher prevalence of having a conversation about birth intervals with their health care providers (aPR = 1.13; 95% CI, 1.03-1.21).

Conclusions: Findings suggest that improving attendance at postpartum visits and evaluating birth interval conversations may strengthen interconception care practices while contextualizing social determinants such as housing stability. Improving uptake of postpartum visits may reduce unintended pregnancy, short birth intervals, and adverse birth outcomes in future pregnancies among women experiencing homelessness.

Objective: If untreated, hepatitis C virus (HCV) leads to poor health outcomes, including liver disease and death, particularly among people with HIV (PWH). We describe trends over time in incidence rates of HCV diagnoses among PWH in the state of Georgia.

Methods: We constructed a retrospective cohort of PWH in Georgia by using matched HIV and HCV case surveillance data from people diagnosed with HCV infection from January 1, 2014, through December 31, 2019. We calculated annual incidence rates per 1000 person-years and estimated trends over time in HCV diagnoses among the cohort of PWH by demographic characteristics and HIV care outcomes using Poisson regression analysis, with α = .05 considered significant.

Results: From 2014 through 2019, among 49 530 PWH in Georgia, 1945 (3.9%) were diagnosed with HCV infection. During this period, overall incidence per 1000 person-years of newly diagnosed HCV infection among PWH decreased from 8.7 to 4.5 (P for trend < .001). However, from 2014 through 2019, the annual incidence rates of PWH who were newly diagnosed with HCV infection increased from 4.6 to 7.1 (P for trend = .003) among people born from 1980 through 1989 and from 3.3 to 12.8 (P for trend < .001) among people born in 1990 or later.

Conclusion: Strategies are needed to increase prevention, diagnosis, and treatment of HIV/HCV coinfection, particularly among PWH born in 1980 and later. Routine linkage of state surveillance data can inform prioritization of PWH at highest risk of HCV infection.

Objectives: Asthma disproportionately affects Black people and people with low incomes, but Medicaid expansion (hereinafter, expansion) data on these populations are limited. We investigated health care use among adults with asthma, before and after expansion, and examined whether asthma-related health care use after expansion varied by demographic characteristics.

Methods: We analyzed data from the 2011-2013 and 2015-2019 Behavioral Risk Factor Surveillance System Adult Asthma Call-Back Survey on participants aged 18-64 years with current asthma and low incomes in 23 US states. We assessed 5 asthma-related outcomes, including medical visits (routine and emergency) and medication use, for expansion and nonexpansion groups. We used t tests to compare weighted percentages and 95% CIs, then performed adjusted difference-in-differences analyses. Secondary analyses stratified data by race, ethnicity, and sex.

Results: Primary analyses (N = 10 796) found no significant associations between expansion and any outcome. Analyses stratified by race and ethnicity found no significant changes (eg, asthma controller medication use among non-Hispanic Black participants in the expansion group was 24.1% [95% CI, 14.4%-37.5%] in 2011-2013 and 35.5% [95% CI, 27.0%-45.1%] in 2015-2019; P = .13). Use of asthma controller medication increased significantly among non-Hispanic Other participants in the nonexpansion group (2011-2013: 16.0% [95% CI, 9.5%-25.5%]; 2015-2019: 40.2% [95% CI, 25.5%-56.8%]; P = .01). Asthma-related hospitalizations decreased significantly among women in the expansion group: 2011-2013 (7.8%; 95% CI, 5.3%-11.3%) and 2015-2019 (3.5%; 95% CI, 2.5%-4.9%) (P = .009).

Conclusions: Investigating factors other than health insurance (eg, social determinants of health) that influence the use of asthma-related health care could advance knowledge of potential strategies to advance health equity for adults with asthma and lower incomes.

Objectives: The Centers for Disease Control and Prevention (CDC) needs leaders at all levels who can address technical and adaptive challenges in a changing public health landscape. We assessed the feasibility of implementing an enterprise-wide leadership development model.

Methods: In June 2023, we launched a pilot program, Learn and Lead, for nonsupervisory staff in early and mid-career levels. One hundred sixty-nine participants registered, and 149 completed at least 6 weeks of the 8-week program. We gathered quantitative and qualitative data through weekly electronic surveys and in-depth interviews. We calculated frequencies for closed-ended Likert-scale items and performed content analysis of open-ended items to assess most frequently mentioned themes. We based the pilot's design on CDC's leadership development framework to assess application of the framework and alignment of curriculum to the framework.

Results: Three themes emerged: logistics and facilitation, leadership development curriculum, and making connections with self and others. Findings for logistics and facilitation highlighted preferences for course length, small breakout groups, mixed weeks, and value of staff support. Findings for the leadership development curriculum underscored the relevance of the US Office of Personnel Management's fundamental competencies to leadership development. Findings for making connections with self and others supported the cohort model and the importance of networking.

Conclusions: The pilot curriculum aligned well with the CDC leadership development framework. Feedback provided by pilot participants is being used to help shape CDC's ongoing leadership development efforts.

Public health policy interventions are associated with many important public health achievements. To provide public health practitioners and decision makers with practical approaches for examining and employing evidence-based public health (EBPH) policy interventions, we describe the characteristics and benefits that distinguish EBPH policy interventions from programmatic interventions. These characteristics include focusing on health at a population level, focusing on upstream drivers of health, and involving less individual action than programmatic interventions. The benefits of EBPH policy interventions include more sustained effects on health than many programs and an enhanced ability to address health inequities. Early childhood education and universal preschool provide a case example that illustrates the distinction between EBPH policy and programmatic interventions. This review serves as the foundation for 3 concepts that support the effective use of public health policy interventions: applying core component thinking to understand the population health effects of EBPH policy interventions; understanding the influence of existing policies, policy supports, and the context in which a particular policy is implemented on the effectiveness of that policy; and employing a systems thinking approach to identify leverage points where policy implementation can have a meaningful effect.

Objectives: Information about homelessness among women is conflicting. We examined changes in the number and rate of various types of homelessness among females in multiple population groups from 2018 through 2022.

Methods: We used 5 years of population data (2018-2022) from the US Department of Housing and Urban Development (HUD) and the US Department of Veterans Affairs (VA). We performed descriptive analyses to examine changes in rates of homelessness over time and differences in rates of homelessness between general and veteran populations.

Results: From 2018 through 2022, there were major increases in rates of unsheltered homelessness among females (25.1%) and males (17.3%) in the general population, which outpaced increases in general population birth rates. Although the percentage change in the proportion of females among all people experiencing unsheltered homelessness grew by 4.0%, the proportion of females among all veterans experiencing unsheltered homelessness grew by 26.3%.

Conclusions: These findings highlight the growing problem of unsheltered homelessness in the general population. Prevention efforts should be focused particularly on the female, especially veteran female, population.

Objectives: To build on the success of wastewater surveillance during the COVID-19 pandemic, jurisdictions funded under the Centers for Disease Control and Prevention National Wastewater Surveillance System are looking to expand their wastewater programs to detect more pathogens. However, many public health agencies do not know how to use the collected wastewater data to formulate public health responses, underscoring a need for guidance. To address this knowledge gap, the Houston Health Department (HHD) developed a novel response framework that outlines an internal action plan that is tailored by pathogen type after detection of various pathogens in wastewater.

Materials and methods: In July 2023, HHD met with subject matter experts (eg, bureau chiefs, program managers) in internal departments, including epidemiology, immunization, and health education, to discuss the general outline of the response framework and each department's anticipated role after pathogen detection.

Results: The internal framework established a flow for notifications and the actions to be taken by departments in HHD, with the goals of (1) ensuring timely and efficient responses to pathogen detections, (2) creating accountability within departments for taking their assigned actions, and (3) making certain that HHD was prepared for intervention implementation when a new pathogen was detected.

Practice implications: As more public health agencies expand their wastewater surveillance programs to target additional pathogens, development of internal action plans tailored to departmental capacity and programs is an important step for public health agencies. The information compiled in this response framework can be a model for other public health agencies to adopt when expanding the scope of their wastewater monitoring systems.
