Access to contraception is an important public health issue in the United States (U.S.), as it plays a fundamental role in preventing unintended pregnancies and improving maternal and child health outcomes. However, significant disparities in access persist in the United States, particularly among uninsured and underinsured women. These women with no or limited health insurance often experience multiple barriers, including cost, limited service availability, inadequate information, lack of access to the full range of contraceptive methods and, leading to unmet needs for contraception. The objective of this scoping review is to map evidence of intervention strategies aimed at improving access to contraceptive services for uninsured and underinsured women in the United States. The review will follow Arksey and O’Malley’s 2005 five-stage scoping review framework. We will conduct a comprehensive literature search of publications from January 2005 to June 2025 on electronic databases such as PubMed, Scopus, CINAHL, Embase, and Web of Science, as well as ScienceDirect, EMBASE, CINAHL, and PsycINFO. The PCC (Population, Concept, Context) criteria will guide study selection, focusing on interventions targeting uninsured and underinsured women in the U.S. that aim to improve contraceptive access. Two reviewers will independently screen the title, abstract and full text. We will use the TIDieR (Template for Intervention Description and Replication) checklist for data extraction to ensure comprehensive reporting of interventions. We will use narrative synthesis to analyze and summarize findings numerically and thematically, guided by Andersen’s Behavioral Model of Health Services Use framework. This scoping review will provide a comprehensive overview of intervention efforts aimed at improving access to contraception among uninsured and underinsured women in the U.S. We expect to identify strategies, programs, and policy-related interventions among this population. Based on the findings from this review, recommendations will be made for future research, program development, and policy.

Background: College students’ well-being is a critical determinant of academic success, and for Native American students, cultural strengths, resilience, and community support are key in fostering persistence in higher education. Alongside these assets, health behaviors are key contributors to psychological well-being (PWB) and academic performance. This study examined how modifiable health behaviors, such as physical activity (PA) and sleep duration, relate to PWB and academic performance among Native American college students. Methods: A secondary data analysis was conducted using a nationally representative sample of Native Americans (N = 1914) from the Spring 2023 American College Health Association-National College Health Assessment (ACHA-NCHA) survey. Independent variables include meeting PA guidelines (≥150 min moderate or ≥75 min vigorous/week) and sleep duration (categorized as poor or good). The Diener Flourishing Scale measured PWB. Academic performance was measured based on self-reported cumulative grade averages. Findings: Biological sex and PA were significantly associated, χ² = 40.60, p < 0.001, with a higher proportion of males meeting PA guidelines. Students with good sleep reported higher PWB than others, F(1, 1817) = 62.08, p < 0.001. Similarly, students who met PA guidelines reported higher PWB, F(1, 1817) = 35.71, p < 0.001. Poor sleep was associated with lower odds of higher academic performance (B = −0.33, p < 0.001). Contrarily, PA was not significant (p = 0.350). PWB was positively associated with academic performance (B = 0.031, p < 0.001). Conclusions: Sleep and PWB are key factors associated with both PWB and academic performance, while PA is associated with PWB. These findings highlight the importance of relevant interventions that promote these factors to support overall well-being, academic success, and retention among Native American college students.

Background: Heavy alcohol consumption is associated with adverse health outcomes; however, its relationship with coronary heart disease (CHD) and angina remains unclear owing to behavioral, demographic, and clinical factors. Objectives: This study aimed to estimate the survey-weighted association between heavy alcohol consumption and self-reported angina or CHD among U.S. adults. Methods: We analyzed Behavioral Risk Factor Surveillance System (BRFSS) data from 2016 - 2021 for 2,586,321 adults. The outcome was self-reported angina or CHD (CVDCRHD4). Heavy alcohol consumption was defined using CDC-calculated BRFSS heavy-drinking variables corresponding to > 14 drinks/week for men and > 7 drinks/week for women. Survey-weighted logistic regression accounted for BRFSS weights, strata, and primary sampling units. Adjusted models included age, sex, race/ethnicity, smoking status, physical activity, and overweight/obesity. Results: The weighted prevalence of angina or CHD was 4.11%, and the weighted prevalence of heavy alcohol consumption was 6.33%. Heavy alcohol consumption was associated with lower odds of angina or CHD (adjusted odds ratio [aOR] = 0.66; 95% confidence interval [CI], 0.62 - 0.71). Exploratory subgroup analyses suggested variation among demographic and behavioral groups. Conclusions: In this cross-sectional BRFSS analysis, heavy alcohol consumption was inversely associated with self-reported angina or CHD. These findings should not be interpreted as evidence of a protective effect because reverse causation, survivor bias, residual confounding, and post-diagnosis changes in drinking behavior may explain the observed association. Longitudinal studies are needed to clarify causal relationships.
