An Introduction to Longitudinal Synthetic Cohorts for Studying the Life Course Drivers of Health Outcomes and Inequalities in Older Age
Kezios KL, Glymour MM and Zeki Al Hazzouri A
Research on the drivers of health across the life course would ideally be based in diverse longitudinal cohorts that repeatedly collect detailed assessments of risk factors over the full life span. However, few extant data sources in the US possess these ideal features. A "longitudinal synthetic cohort"-a dataset created by stacking or linking multiple individual cohorts spanning different but overlapping periods of the life course-can overcome some of these challenges, leveraging the strengths of each component study. This type of synthetic cohort is especially useful for aging research; it enables description of the long-term natural history of disease and novel investigations of earlier-life factors and mechanisms shaping health outcomes that typically manifest in older age, such as Alzheimer's disease and related dementias (ADRD).
A Review of Causal Inference Methods for Estimating the Effects of Exposure Change When Incident Exposure Is Unobservable
Liu F, Duchesneau ED, Lund JL and Jackson JW
Research questions on exposure change and health outcomes are both relevant to clinical and policy decision making for public health. Causal inference methods can help investigators answer questions about exposure change when the first or incident exposure is unobserved or not well defined. This review aims to help researchers conceive of helpful causal research questions about exposure change and understand various statistical methods for answering these questions to promote wider adoption of causal inference methods in research on exposure change outside the field of pharmacoepidemiology.
Microbiota-Gut-Brain Axis in Psychiatry: Focus on Depressive Disorders
Wang IC, Buffington SA and Salas R
Gut microbiota contribute to several physiological processes in the host. The composition of the gut microbiome is associated with different neurological and neurodevelopmental diseases. In psychiatric disease, stress may be a major factor leading to gut microbiota alterations. Depressive disorders are the most prevalent mental health issues worldwide and patients often report gastrointestinal symptoms. Accordingly, evidence of gut microbial alterations in depressive disorders has been growing. Here we review current literature revealing links between the gut microbiome and brain function in the context of depression.

Defining, measuring, and evaluating prenatal care in insurance claims data
Simmons E, Dissanayake MV, Kahrs JC, Latour CD, Olawore O, Kucirka LM and Wood ME
The objective of this paper is to discuss the complexities of identifying prenatal care visits in insurance claims databases, review existing methods to identify prenatal care encounters, and explore how different study goals should inform the definition of prenatal care employed by investigators.
ENVIRONMENTAL INFLUENCES ON ACADEMIC PROFICIENCY
Grineski S, Alexander C, Allain ML, Clark AS, Collins TW, Goodwin E, Mullen CJ, Scott M, Shaker Y, Ramos KD, Renteria RA and Rubio R
Environmental conditions impact the well-being of populations worldwide, including the academic proficiency of youth. The current review summarizes the role of environmental influences (i.e., air pollution, greenspace, noise, and disasters) on academic proficiency.
Current approaches to measuring local racial and ethnic residential segregation in population health studies
Kershaw KN, Barber S and Hicken MT
Segregation has traditionally been measured at the metropolitan area or county level, but a growing number of population health studies have measured segregation at the neighborhood or local level. In this review we highlight the ways local racial and ethnic residential segregation has been measured in recently published population health studies (June 1, 2019-June 30, 2022).
Environmental, Sociocultural, Behavioral, and Biological Factors Associated with Cognitive Decline, Alzheimer's Disease, and Other Types of Dementia in Black Americans
Byrd DR, Martin DA and Joseph RP
This narrative review summarizes environmental, sociocultural, behavioral, and biological factors associated with cognitive decline and dementia in Black Americans.
Weighing risks and benefits in the presence of competing risks
Lesko CR, Zalla LC, Heyward J, Joseph C and Edwards JK
When competing events occur, there are two main options for handling them analytically that invoke different assumptions: 1) censor person-time after a competing event (which is akin to assuming they could be prevented) to calculate a conditional risk; or 2) do not censor them (allow them to occur) to calculate an unconditional risk. The choice of estimand has implications when weighing the relative frequency of a beneficial outcome and an adverse outcome in a risk-benefit analysis.
Determinants and Assessment of Menstrual Blood Flow
Liang J, Ali F, Ramaiyer M and Borahay MA
a)The modifiable and non-modifiable determinants and the currently available methods of assessment of menstrual blood flow will be discussed, with the goal of helping healthcare providers, researchers, and those interested in public health.

A Review of the Causal Decomposition Framework for Modeling Interventions that Reduce Disparities
Qin MM and Jackson JW
This review summarizes recent developments in causal decomposition analysis (CDA), a modeling framework for reducing disparities. Rather than the current or past drivers of a disparity, CDA estimates the effect of an to change the distribution of a variable or set of variables that are distributed differently or have different effects between groups. Furthermore, CDA clarifies how, through covariate adjustment, ethics and justice are implicit in any definition of disparity and may be incorporated into an intervention.
Structural Racism in Cervical Cancer Care and Survival Outcomes: A Systematic Review of Inequities and Barriers
Schaefer A, Rockson A, Islam JY, LaForest M, Jenkins NC, Obi NC, Ashrafi A, Wingard J, Tejada J, Tang W, Commaroto SA, O'Shea S, Tsui J and Llanos AAM
Despite cervical cancer (CC) being a cancer that can be eliminated, CC disparities persist such that minoritized populations shoulder a disproportionate mortality burden. This may reflect upstream, fundamental drivers of health that impede equitable access to prevention, screening, early detection, and treatment among some groups. This systematic review summarizes evidence on the relationships between structural racism and CC care across the continuum.
