Project description:In order to gain insights into how the effects of the uneven adoption of Medicaid expansion varies across the rural/urban spectrum and between racial/ethnic groups in the United States, this research used the fertility question in the 2011-2015 American Community Survey to link infants' records to their mothers' household health insurance status. This preliminary exploration of the Medicaid expansion used logistic regression to examine the probability that an infant will be born without health insurance coverage. Overall, the states that adopted Medicaid expansion improved the health insurance coverage for households with infants. However, rural households with infants report lower percentages of coverage than urban households with infants. Furthermore, the rural/urban gap in health insurance coverage is wider in states that adopted the Medicaid expansion. Additionally, Hispanic infants remain significantly less likely to have health insurance coverage compared to Non-Hispanic White infants. Understanding infant health insurance coverage across ethnic/racial groups and the rural/urban spectrum will become increasingly important as the U.S. population transitions to a minority-majority and also becomes more urban. Although not a perfect solution, our findings showed that the Medicaid expansion of health insurance coverage had a mainly overall positive effect on the percentage of U.S. households with infants who have health insurance coverage.
Project description:ObjectiveTo estimate whether racial/ethnic behavioral health service disparities are likely to be reduced through insurance expansion coverage expected through the Affordable Health Care Act.Data sourcesPooled data from the nationally representative NIMH Collaborative Psychiatric Epidemiological Studies (2001-2003).Study designWe employ a novel reweighting method to estimate service disparities in the presence and absence of insurance coverage.Data collectionAccess to care was assessed by whether any behavioral health treatment was received in the past year. Need was determined by presence of prior year psychiatric disorder, psychiatric diagnoses, physical comorbidities, gender, and age.Principal findingsImproving patient education and availability of community clinics, combined with insurance coverage reduces service disparities across racial/ethnic groups.However, even with expanded insurance coverage, approximately 10 percent fewer African Americans with need for behavioral health services are likely to receive services compared to non-Latino whites while Latinos show no measurable disparity.ConclusionsExpansion of insurance coverage might have different effects for racial/ethnic groups, requiring additional interventions to reduce disparities for all groups.
Project description:BackgroundNew treatment options and supportive care measures have greatly improved survival of patients with non-Hodgkin lymphoma (NHL) but may not be affordable for those with no insurance or inadequate insurance.MethodsUsing data from the Surveillance, Epidemiology, and End Results database, we estimated overall and cause-specific survival according to insurance status within 3 years after diagnosis of patients diagnosed with NHL in the U.S. in the period 2007-2011. Because NHL is a heterogeneous condition, we also examined survival in diffuse large B-cell lymphoma (DLBCL).ResultsSurvival was higher for patients with non-Medicaid insurance compared with either uninsured patients or patients with Medicaid. For patients with any NHL, the 3-year survival estimates were 68.0% for uninsured patients, 60.7% for patients with Medicaid, and 84.9% for patients with non-Medicaid insurance. Hazard ratios (HRs) for uninsured and Medicaid-only patients compared with insured patients were 1.92 (95% confidence interval [CI]: 1.76-2.10) and 2.51 (95% CI: 2.36-2.68), respectively. Results were similar for patients with DLBCL, with survival estimates of 68.5% for uninsured patients (HR: 1.78; 95% CI: 1.57-2.02), 58%, for patients with Medicaid (HR: 2.42; 95% CI: 2.22-2.64), and 83.3% for patients with non-Medicaid insurance. Cause-specific analysis showed survival estimates of 80.3% for uninsured patients (HR: 1.83; 95% CI: 1.62-2.05), 77.7% for patients with Medicaid (HR: 2.23; 95% CI: 2.05-2.42), and 90.5% for patients with non-Medicaid insurance.ConclusionLack of insurance and Medicaid only were associated with significantly lower survival for patients with NHL. Further evaluation of the reasons for this disparity and implementation of comprehensive coverage for medical care are urgently needed.
Project description:The high disease burden of influenza in elderly and chronically ill adults may be due to the suboptimal effectiveness and mismatch of the conventional trivalent influenza vaccine (TIV). This study evaluated the cost-effectiveness of quadrivalent (QIV), adjuvanted trivalent (ATIV), and high-dose quadrivalent (HD-QIV) vaccines versus TIV used under the current Korean National Immunization Program (NIP) in older adults aged ≥65 years. We also evaluated the cost-effectiveness of programs for at-risk adults aged 19-64 and adults aged 50-64. A one-year static population model was used to compare the costs and outcomes of alternative vaccination programs in each targeted group. Influenza-related parameters were derived from the National Health Insurance System claims database; other inputs were extracted from the published literature. Incremental cost-effectiveness ratios (ICERs) were assessed from a societal perspective. In the base case analysis (older adults aged ≥65 years), HD-QIV was superior, with the lowest cost and highest utility. Compared with TIV, ATIV was cost-effective (ICER $34,314/quality-adjusted life-year [QALY]), and QIV was not cost-effective (ICER $46,486/QALY). The cost-effectiveness of HD-QIV was robust for all parameters except for vaccine cost. The introduction of the influenza NIP was cost-effective or even cost-saving for the remaining targeted gr3oups, regardless of TIV or QIV.
Project description:IntroductionRacial disparities in dementia incidence exist, but less is known about their presence and drivers among middle-aged adults.MethodsWe used time-to-event analysis among a sample of 4378 respondents (age 40-59 years at baseline) drawn from the third National Health and Nutrition Examination Surveys (NHANES III) with administrative linkage-spanning the years 1988-2014-to evaluate potential mediating pathways through socioeconomic status (SES), lifestyle, and health-related characteristics.ResultsCompared with Non-Hispanic White (NHW) adults, Non-White adults had a higher incidence of AD-specific (hazard ratio [HR] = 2.05, 95% confidence interval [CI]: 1.21, 3.49) and all-cause dementia (HR = 2.01, 95% CI: 1.36, 2.98). Diet, smoking, and physical activity were among characteristics on the pathway between race/ethnicity, SES, and dementia, with health-mediating effects of smoking and physical activity on dementia risk.DiscussionWe identified several pathways that may generate racial disparities in incident all-cause dementia among middle-aged adults. No direct effect of race was observed. More studies are needed to corroborate our findings in comparable populations.
Project description:BackgroundThis study aims to better understand differing pain experiences across U.S. racial/ethnic subgroups by estimating racial-ethnic disparities in both pain intensity and domain-specific pain-related interference. To address this issue, we use a nationally representative sample of non-Hispanic White, non-Hispanic Black, and Hispanic adults ages 50+ who report recently experiencing pain.MethodsUsing data from the 2010 wave of the Health and Retirement Study (HRS; N = 684), we conducted a series of multivariate analyses to assess possible racial/ethnic disparities in pain intensity and 7 domains of pain interference, controlling for relevant sociodemographic variables and other health problems.ResultsBlack and Hispanic participants reported higher pain intensity than White participants after controlling for socioeconomic status (SES) and other health conditions. Both Black and Hispanic individuals reported more domain-specific pain interference in bivariate analyses. In multivariate analyses, Black (vs White) participants reported significantly higher levels of pain interference with family-home responsibilities, occupation, sexual behavior, and daily self-care. We did not find significant Hispanic-White differences in the 7 pain interference domains, nor did we find Black-White differences in 3 domains (recreation, social activities, and essential activities).ConclusionsOur findings highlight the need for using multidimensional measures of pain when assessing for possible pain disparities with respect to race/ethnicity. Future studies on pain interventions should consider contextualizing the pain experience across different racial subgroups to help pain patients with diverse needs, with the ultimate goal of reducing racial/ethnic disparities in pain.
Project description:IntroductionAlthough evidence suggests physical activity (PA) may be associated with mental well-being at older ages, it is unclear whether some types of PA are more important than others. The purpose of this study is to investigate associations of monitored total PA under free-living conditions, self-reported leisure-time PA (LTPA), and walking for pleasure with mental well-being at age 60-64 years.MethodsData on 930 (47%) men and 1,046 (53%) women from the United Kingdom Medical Research Council (MRC) National Survey of Health and Development collected in 2006-2011 at age 60-64 were used in 2013-2014 to test the associations of PA (PA energy expenditure and time spent in different intensities of activity assessed using combined heart rate and acceleration monitors worn for 5 days, self-reported LTPA, and walking for pleasure) with the Warwick-Edinburgh Mental Well-being Scale (WEMWBS; range, 14-70).ResultsIn linear regression models adjusted for gender, long-term limiting illness, smoking, employment, socioeconomic position, personality, and prior PA, those who walked for >1 hour/week had mean WEMWBS scores 1.47 (95% CI=0.60, 2.34) points higher than those who reported no walking. Those who participated in LTPA at least five times/month had WEMWBS scores 1.25 (95% CI=0.34, 2.16) points higher than those who did not engage in LTPA. There were no statistically significant associations between free-living PA and WEMWBS scores.ConclusionsIn adults aged 60-64 years, participation in self-selected activities such as LTPA and walking are positively related to mental well-being, whereas total levels of free-living PA are not.
Project description:ObjectiveTo test the impact of the dependent coverage expansion (DCE) on insurance disparities across race/ethnic groups.Data sources/study settingSurvey data from the National Survey of Drug Use and Health (NSDUH).Study designTriple-difference (DDD) models were applied to repeated cross-sectional surveys of the U.S. adult population.Data collection/extraction methodsData from 6 years (2008-2013) of the NSDUH were combined.Principal findingsFollowing the DCE, the relative odds of insurance increased 1.5 times (95 percent CI 1.1, 1.9) among whites compared to blacks and 1.4 times (95 percent CI 1.1, 1.8) among whites compared to Hispanics.ConclusionsHealth reform efforts, such as the DCE, can have negative effects on race/ethnic disparities, despite positive impacts in the general population.
Project description:Background: Despite the rising prevalence of infertility, studies have indicated that in the United States fertility awareness remains low. No published study to date, however, has investigated the impact of any racial or ethnic disparities in fertility awareness. Materials and Methods: We conducted a cross-sectional survey of people self-identifying as female, aged 18-45 years, via Amazon Mechanical Turk in August 2020. The study was approved by the institutional review board at the University of Colorado. The survey consisted of demographic questions and a validated questionnaire, the Fertility and Infertility Treatment Knowledge Score (FIT-KS). Participants were classified as non-Hispanic White (NHW) or "Minority" race/ethnicity. Results: A total of 476 women completed the survey, 405 of which were included in analysis. Of those, 54.6% self-identified as NHW and 45.4% were in the Minority group. The median FIT-KS was 51.7% (16 items answered correctly). The Minority group scored significantly lower than the NHW participants overall (58.6% vs. 48.3%, p < 0.001) and in all three subscales (p < 0.05). The Minority group was significantly more likely to underestimate the rate of miscarriage (47.3% vs. 32.6%, p = 0.003) and had a lower awareness of risk factors that can impact fertility including smoking (88.7% vs. 71.6%, p < 0.001), obesity (90.5% vs. 70.5%, p < 0.001), and/or a history of gonorrhea/chlamydia infection (83.7% vs. 64.7%, p < 0.001). Conclusions: Minority women appear to have a lower fertility awareness than their NHW counterparts. Addressing these disparities and improving fertility education in diverse communities may lead to a reduction in clinically significant infertility disparities.
Project description:ObjectiveTo examine the effect of Medicare Part D on racial/ethnic disparities in having any drug coverage and in sources of payment for drug expenditure.MethodsWe used nationally representative data on whites, African-Americans, and Hispanics aged 55 and older from the 2002-2009 Medical Expenditure Panel Survey to analyze disparities in having any drug coverage and in sources of coverage for individuals aged 65 and older as compared with those for adults aged 55-63 without Medicare.ResultsThere was no disparity in the probability of drug coverage for African-American or Hispanic compared to white Medicare beneficiaries, before or after 2006. There were, however, differences in the sources of coverage. African-Americans and Hispanics over the age of 65 had lower rates of private coverage than whites. This disparity in private coverage was completely offset by minorities' higher rates of drug coverage through Medicaid before 2006 and through Part D since 2006. In contrast, among individuals aged 55-63, there are large and persistent disparities in the probability of having drug coverage throughout the period.DiscussionPronounced racial/ethnic disparities in drug coverage in the years just before Medicare eligibility are eliminated by access to public coverage at age 65. This was true even before the introduction of Part D.
