Introduction:
Although the association between health insurance coverage and access to care is well documented, it is unclear whether the deleterious effects of being uninsured are strictly contemporaneous or whether previous disruptions in coverage have persistent effects. This study addresses this issue using nationally representative data cover...
This cohort study assesses associations of a prior coverage disruption with mortality risk among large, nationally representative cohorts of working-age adults with public or private health insurance coverage.
Background:
Asians are the fastest-growing racial/ethnic minority group in the USA and many face communication barriers when seeking health care. Given that a high proportion of Asians are immigrants and have limited English proficiency, poor patient-provider communication may explain Asians' relatively low ratings of care. Though Asians are lingu...
Introduction:
In the U.S., rural residents have poorer health than urban residents and this disadvantage is growing. Therefore, it is important to understand rural-urban differences in access to medical care. This study compared the percentage of individuals with a usual source of care and characteristics of usual source of care providers across 3...
Background
Individuals with limited English proficiency (LEP) have worse healthcare access and report lower quality of care compared to individuals who are proficient in English. Policy efforts to improve patient-provider communication for LEP individuals have been going on for decades but linguistic disparities persist.
Objective
To describe tren...
Prescription drugs can effectively treat many diseases, improving quality of life, life expectancy, and population health. However, prescription drug spending has been rising rapidly in the United States¹ resulting in concerns about affordability and patient access. Health insurance is strongly associated with prescription drug access in cross-sect...
Objective:
To investigate the relationship between the percent uninsured in a county and expenditures associated with the typical emergency department visit.
Data sources:
The Medical Expenditure Panel Survey linked to county-level data from the American Community Survey, the Healthcare Cost and Utilization Project, and the Area Health Resources...
Background:
Community Health Centers (CHCs) funded by Section 330 of the Public Health Service Act are an essential part of the health care safety net in the US. The Patient Protection and Affordable Care Act expanded the program significantly, but the extent to which the availability of CHCs improve access to care in general is not clear. In this...
Newly available longitudinal survey data show that people who lacked health insurance in 2013 and gained coverage through Medicaid or the Marketplaces in 2014 were far more likely to obtain a usual source of care and receive preventive care services than their counterparts who remained uninsured in 2014.
Background:
Starting in September of 2010, the Patient Protection and Affordable Care Act required most health insurance policies to cover evidence-based preventive care with no cost-sharing (no copays, coinsurance, or deductibles). It is unknown, however, whether declines in out-of-pocket costs for preventive services are large enough to prompt i...
Reducing disparities in access to health care is a long-standing objective of the federal government. Building on research showing that marriage can provide important resources for obtaining needed health care, we suggest that racial and ethnic differences in marriage could explain persistent disparities in access. Using data from MEPS and NLSY we...
Eliminating disparities in health and health care is a long-standing objective of the US government. Racial and ethnic differences in insurance coverage pose a major obstacle to achieving this objective. With important coverage provisions of the Affordable Care Act beginning to take effect, we propose a new way of conceptualizing and quantifying th...
We explored the association between community racial/ethnic composition and obesity risk.
In this cross-sectional study, we used nationally representative data from the Medical Expenditure Panel Survey linked to geographic data from the US Decennial Census and Census Business Pattern data.
Living in communities with a high Hispanic concentration (≥...
OBJECTIVE: Understanding factors associated with home health care use is an important public health concern as policymakers, older adults, and families are seeking ways to promote aging in place by ensuring accessibility to health-related services at home. This study investigates whether the interaction between individual race/ethnicity and communi...
Millions of people in the United States do not have health insurance, and wide racial and ethnic disparities exist in coverage. Current research provides a limited description of this problem, focusing on the number or proportion of individuals without insurance at a single time point or for a short period. Moreover, the literature provides no sens...
To investigate whether the interaction between individual race/ethnicity and community racial/ethnic composition is associated with health-related home care use among elderly persons in the United States.
A nationally representative sample of community-dwelling elders aged 65+ from the 2000 to 2006 Medical Expenditure Panel Survey (N=23,792) linked...
We investigate the extent to which antidepressant use among adolescents varies across racial and ethnic subgroups. Using a representative sample of U.S. adolescents, we find that non-Hispanic White adolescents are over twice as likely as Hispanic adolescents, and over five times as likely as non-Hispanic Black adolescents to use antidepressants. Re...

Structural Equation Modeling with latent variables (SEM) is a powerful tool for social and behavioral scientists, combining many of the strengths of psychometrics and econometrics into a single framework. The most common estimator for SEM is the full-information maximum likelihood estimator (ML), but there is continuing interest in limited informat...
We sought to examine the relationship between living arrangements and obtaining preventive care among the elderly population.
We obtained data on 13,038 community-dwelling elderly persons from the 2002 to 2005 Medical Expenditure Panel Survey and used multivariate logistic regression models to estimate the likelihood of preventive care use among el...
OBJECTIVE: To examine the impact of household living arrangements on the use of preventive care among community-dwelling older adults. METHODS: Using data from the 2002-2005 Medical Expenditure Panel Survey, this cross-sectional study analyzed 13,038 U.S. community-dwelling elders age 65 and older whose living arrangements included 38% living alone...
Research suggests that community-level poverty is associated with access to health care net of individual-level characteristics,
but no research investigates whether this association differs by individual-level income. Using data from the Medical Expenditure
Panel Surveys, the U.S. Census Bureau and the Health Resource and Services Administration,...
This article is an empirical evaluation of the choice of fixed cutoff points in assessing the root mean square error of approximation (RMSEA) test statistic as a measure of goodness-of-fit in Structural Equation Models. Using simulation data, the authors first examine whether there is any empirical evidence for the use of a universal cutoff, and th...
To document and explain racial/ethnic differences in the use of stimulant drugs among US children.
We use a nationally representative sample of children ages 5-17 years old from the Medical Expenditure Panel Survey (MEPS) for the years 2000-2002. We estimate race-specific means and regressions to highlight differences across groups in individual/fa...
A growing number of Latinos are moving to nonmetro areas, but little research has examined how this trend might affect the Latino-disadvantage in access to healthcare.
We investigate health care access disparities between non-Latino whites and Latinos of Mexican origin, and whether the disparities differ between metro and nonmetro areas.
A series o...
This article compares maximum likelihood (ML) estimation to three variants of two-stage least squares (2SLS) estimation in structural equation models. The authors use models that are both correctly and incorrectly specified. Simulated data are used to assess bias, efficiency, and accuracy of hypothesis tests. Generally, 2SLS with reduced sets of in...
Many Americans do not have access to adequate medical care. Previous research on this problem focuses primarily on individual-level determinants of access such as income and insurance coverage. The role of community-level factors in helping or hindering individuals in obtaining needed medical care, however, has not received much attention. We addre...
The substantial racial and ethnic disparities in access to and use of health services are well documented. A number of studies highlight factors such as health insurance coverage and socioeconomic differences that explain some of the differences between groups, but much remains unexplained. We build on this previous research by incorporating additi...
This study addresses two questions: Is stepfamily formation associated with the likelihood that adolescents will initiate alcohol use, and if so, does this association differ by the type of single-parent families from which adolescents move or the type of stepfamilies to which they move? The author found that adolescents who moved to stepfamilies f...
Most research on access to health care focuses on individual-level determinants such as income and insurance coverage. The role of community-level factors in helping or hindering individuals in obtaining needed care, however, has not received much attention. We address this gap in the literature by examining how neighborhood socioeconomic disadvant...
Studies examining predictors of preventive service utilization generally focus on individual characteristics and ignore the role of contextual variables. To help address this gap in the literature, the present study investigates whether county-level characteristics, such as racial and ethnic composition, are associated with the use of preventive se...
A key advantage of the root mean square error of approximation (RMSEA) is that under certain assumptions, the sample estimate has a known sampling distribution that allows for the computation of confidence intervals. However, little is known about the finite sampling behaviors of this measure under violations of these ideal asymptotic conditions. T...
To describe changes in health services use and expenditures within the Medicaid population between 1987 and 1997 and to estimate the extent to which the increase in Health Maintenance Organization (HMO) enrollment has influenced these changes.
Individuals under the age of 65 years in the 1987 National Medical Expenditure Survey and the 1997 Medical...
OBJECTIVE. To describe changes in health services use and expenditures within the Medicaid population between 1987 and 1997 and to estimate the extent to which the increase in Health Maintenance Organization (HMO) enrollment has influenced these changes. SUBJECTS. Individuals under the age of 65 years in the 1987 National Medical Expenditure Survey...
Since 1970, both the number and proportion of children being parented by a grandparent without the help of a parent has increased substantially. The increase in skipped-generation households has generated much concern from policy makers because such households are, on average, disadvantaged compared with most other household types. One important ch...
Most adult smokers start smoking when they are adolescents and, the prevalence of smoking declines less than other unhealthy behaviors as people mature. Understanding why adolescents start smoking is, therefore, key to developing effective policy aimed at lowering the prevalence of smoking in both children and adults. In this study, I suggest that...
The noncentral chi-square distribution plays a key role in structural equation modeling (SEM). The likelihood ratio test statistic that accompanies virtually all SEMs asymptotically follows a noncentral chi-square under certain assumptions relating to misspecification and multivariate distribution. Many scholars use the noncentral chi-square distri...
It has been suggested by several scholars that debates surrounding the study of mortality could benefit from a framework that integrates social and economic factors with the biological mechanisms of illness and death (Johannson and Mosk, Popul. Stud. 41 (1987) 207-236; Mosley, International Population Conference, Vol. 2, Florence, IUSSP, Liege, 198...
In this article, the authors examine the most common type of improper solutions: zero or negative error variances. They address the causes of, consequences of, and strategies to handle these issues. Several hypotheses are evaluated using Monte Carlo simulation models, including two structural equation models with several misspecifications of each m...

... Food insecurity prevalence in the United States typically hovers around 10% but the prevalence among Blacks (20%) and Hispanics (16%) is much higher when compared to Whites (7%) [6]. Food insecurity is more prevalent among people with T2D when compared to those without (16% versus 9%) [7]. Since following a healthful diet is central to T2D management, food insecurity is a major barrier, especially among underrepresented groups [1]. ...
... The combination of low socioeconomic resources along with the cultural value emphasizing providers' medical knowledge and authority, highlight the potentially critical role of provider communication for stress appraisal, coping behavior, and health outcomes among Chinese American survivors. Unfortunately, this assumption is rarely studied, despite clear evidence that Asian Americans including Chinese Americans have suboptimal communication with providers [22,24,25]. ...
... After drying of the DBS, delivery by post is possible as the stability of the proteins is demonstrated over several days [3]. Nowadays, medical deserts are present, especially in rural areas, making it difficult to access health facilities and the possibility of taking a blood sample [4]. Medical staff are stretched and waiting times are thus increased. ...
... Individuals with LEP are at risk for healthcare disparities related to limited access to health care and not obtaining preventive services, such as cancer screening and early-detection screening (Foiles Sifuentes et al., 2020). A number of factors contribute to poor cancer outcomes, including the following: cultural and ethnic beliefs about cancer, inability to navigate the U.S. medical system, limited access to screening services, lack of health insurance, lack of language-concordant education about cancer and treatments, and institutional barriers impeding access to high-quality cancer care (Berdahl & Kirby, 2019;Perez et al., 2016) (see Figure 1). The diagnosis of cancer may be delayed in patients with LEP because they are less likely to have a regular HCP and often postpone visits because of apprehension or because they do not recognize symptoms of cancer. ...
... [7][8][9][10][11] Prior studies have found that Marketplace coverage is associated with increased access to a usual source of care and pre-scription medications, increased use of inpatient and outpatient care, and higher diagnosis rates of hypertension, but they have not examined pregnant people specifically. [12][13][14][15] Although any type of insurance change may result in interruptions in care, examining transitions into Marketplace coverage during pregnancy is important given the time-sensitive nature of prenatal care use. ...
... They claim that the causality may be an illusion because factors such as adverse selection by purchasers and cream skimming by insurers may lead to reverse causality of the insured's health status on PHI participation behavior, i.e., there is an endogeneity problem that is not addressed (13,14). In addition, the effects of insurance on health service utilization and health expenditure are confirmed to vary among different populations, such as across age (15,16), gender (17,18), income (19,20), or ethnic subgroups (21), between sick and healthy people (22), and across geographical locations (23)(24)(25), which is less considered in the studies of PHI's effects on health. ...
... Greater FQHC accessibility is associated with lower rates of preventable hospitalizations and emergency department visits and higher rates of having a usual source of care and having a doctor visit in the past 12 months. [9][10][11][12][13] NAP funding to increase the number of FQHCs was intended to work synergistically with Medicaid expansion under the Affordable Care Act (ACA) by increasing FQHC accessibility and health care affordability-2 dimensions of health care access 14 -in tandem for low-income U.S. residents. Medicaid expansion extended health insurance coverage to adults aged 19-64 earning up to 138% of the federal poverty level. ...
... This study is related to the research finding that Medicaid expansion has improved general access to health care services (Kirby & Vistnes, 2016;Miller & Wherry, 2017;Simon et al., 2017). However, some studies suggest no effect of the ACA Medicaid expansion on behavioral health treatment utilization (Andrews et al., 2019;Gertner et al., 2020). ...
... Three breast cancer-related preventive services covered under the ACA are mammography screening for women aged 40 years and older, genetic screening and counseling, and preventive medication, for women at high risk for breast cancer (1). Studies examining women's financial burden for breast cancer screening before and after the implementation of the ACA have found a substantial reduction in out-of-pocket (OOP) expense and a marked increase in the proportion of women with zero cost-share associated with their screening mammography service (2)(3)(4). ...
... In addition, Medicaid patients both with and without treatment-resistant depression in this study had higher baseline mental health-related health care resource utilization, compared with the Medicare and commercially insured populations. However, several states have Medicaid behavioral health carve-outs, and more than 40% of Medicaid patients in this study also had health maintenance organization plans, which tend to be more restrictive than other health plans (21). Potentially, the Medicaid population in this study had a greater burden of psychiatric illness, even among those without treatment-resistant depression, compared with the Medicare and commercially insured populations, and less generous insurance benefits would have limited even higher levels of resource use above this elevated baseline. ...
