Randomized Controlled Trial
An RCT to Increase Breast and Colorectal Cancer Screening.
Adherence to breast and colorectal cancer screenings reduce mortality from these cancers, yet screening rates remain suboptimal. This 2 × 2 RCT compared 3 theory-based interventions to usual care to simultaneously increase breast and colon cancer screening in women who were nonadherent to both screenings at study entry. ⋯ The tailored intervention simultaneously supporting both breast and colon cancer screenings significantly improved rates of obtaining one of the screenings and increased receipt of both tests.

Simulation models can improve measurement and understanding of mental health conditions in the population. Major depressive episodes are a common and leading cause of disability but are subject to substantial recall bias in survey assessments. This study illustrates the application of a simulation model to quantify the full burden of major depressive episodes on population health in the U.S. ⋯ Simulation models can address knowledge gaps in disease epidemiology and prevention and improve surveillance efforts. This model quantifies the under-reporting of major depressive episodes and provides parameter estimates for future research. After adjusting for under-reporting, 23.9% of adults have a lifetime history of major depressive episodes, which is much higher than based on self-report alone (14.0%). Far more adults would benefit from depression prevention strategies than what survey estimates suggest.

Medical graduates increasingly need public health skills to equip them to face the challenges of healthcare practice in the 21st century; however, incorporating public health learning within medical degrees remains a challenge. This paper describes the process and preliminary outcomes of the transformation, between 2016 and 2019, of a 5-week public health module taught within an undergraduate medical degree in New Zealand. The previous course consisted of a research project and standalone lectures on public health topics. ⋯ A combination of individual- and population-level case scenarios aim to help students understand the context of health, think critically about determinants of health and health inequities, and develop skills in disease prevention, health promotion, and system change that are relevant to their future clinical careers. The new module is based on contemporary medical education theory, emphasizes reflective practice, and is integrated with other learning in the degree. It challenges students to understand the relevance of public health to every aspect of medicine and equips them with the skills needed to act to improve population health and reduce inequities as health professionals and leaders of the future.

The Affordable Care Act's Medicaid expansion has been found to increase healthcare access among low-income individuals in the general population. Fewer studies have explored the impact of Medicaid expansion on healthcare access among those living with chronic diseases. It is also unclear whether the impact of Medicaid expansion varies across levels of educational attainment or poverty among this subgroup. This study investigates the impact of Medicaid expansion on healthcare access among adults aged 18-64 years living with chronic diseases, as well as its variations across educational attainment and federal poverty levels. ⋯ Medicaid expansion increased healthcare access for low-income individuals living with chronic diseases.

Differences in diet quality across socioeconomic groups are a key contributor to health gradient. An agent-based model was developed to explore how income segregation affects food access for poor households under idealized circumstances where the poor have the same knowledge of and preferences for healthy food as the nonpoor. ⋯ The model demonstrates that even under idealized conditions of perfect information and fully rational consumers, income segregation leads to adverse consequences for healthy food access by the poor. Agent-based modeling is useful to explore important hypothetical scenarios and should be considered as one of many worthwhile complementary frameworks to study complex topics.
