Hispanic healthcare disparities: challenging the myth of a monolithic Hispanic population.

Background:Hispanic Americans are often treated as a monolithic ethnic group with a single pattern of healthcare utilization. However, there could be considerable differences within this population. We examine the association between use of healthcare services and Hispanic Americans’ country of ancestry or origin, language of interview, and length of time lived in the United States. Methods:Our data come from the Medical Expenditure Panel Survey, a nationally representative survey of healthcare use and expenditures. Descriptive statistics and logistic regression results are presented. Results:Multivariate models show that Mexicans and Cubans are less likely, and Puerto Ricans more likely, to have any emergency department visits than non-Hispanic whites. Mexicans, Central American/Caribbeans, and South Americans are less likely to have any prescription medications. All Hispanics are less likely to have any ambulatory visits and prescription medications, whereas only those with a Spanish-language interview are less likely to have emergency department visits and inpatient admissions. More recent immigrants are less likely to have any ambulatory care or emergency department visits, whereas all Hispanics born outside the United States are less likely to have any prescription medications. Conclusions:The Hispanic population is composed of many different groups with diverse health needs and different barriers to accessing care. Misconceptions of Hispanics as a monolithic population lacking within-group diversity could function as a barrier to efforts aimed at providing appropriate care to Hispanic persons and could be 1 factor contributing to inequalities in the availability, use, and quality of healthcare services in this population.

Mental Health and Substance Use Disorders Among Latino and Asian American Lesbian, Gay, and Bisexual Adults

Growing evidence suggests that lesbian, gay, and bisexual adults may be at elevated risk for mental health and substance use disorders, possibly due to anti-gay stigma. Little of this work has examined putative excess morbidity among ethnic/racial minorities resulting from the experience of multiple sources of discrimination. The authors report findings from the National Latino and Asian American Survey (NLAAS), a national household probability psychiatric survey of 4,488 Latino and Asian American adults. Approximately 4.8% of persons interviewed identified as lesbian, gay, bisexual, and/or reported recent same-gender sexual experiences. Although few sexual orientation-related differences were observed, among men, gay/bisexual men were more likely than heterosexual men to report a recent suicide attempt. Among women, lesbian/bisexual women were more likely than heterosexual women to evidence positive 1-year and lifetime histories of depressive disorders. These findings suggest a small elevation in psychiatric morbidity risk among Latino and Asian American individuals with a minority sexual orientation. However, the level of morbidity among sexual orientation minorities in the NLAAS appears similar to or lower than that observed in population-based studies of lesbian, gay, and bisexual adults.

Childhood asthma, chronic illness, and psychiatric disorders.

Asthma is a serious and vexing problem for many children and their families. Asthma, like most syndromes, has many symptoms and potential causes and effects. Studies have shown that pediatric asthma is associated with psychiatric disorders, but the specificity and temporality of these relations is not well known. This study examined the associations between any and specific psychiatric disorders and both childhood asthma and other childhood chronic illnesses. The study used the Methods for the Epidemiology of Child and Adolescent Mental Disorders data, a four-site, community-based study of 1,285 pairs of youths and caretakers. Psychiatric disorders were assessed using the Diagnostic Interview Schedule for Children (DISC 2.3). Methods for the Epidemiology of Child and Adolescent Mental Disorders was also used to assess individual characteristics, parental reports of asthma, and other chronic illnesses. Asthma and ‘other’ chronic illnesses were associated with different psychiatric disorders. In particular, having a history of asthma was associated with having an anxiety disorder, after adjustment for potential confounding, but was not associated with having an affective disorder. Having a chronic illness other than asthma or cancer was associated with having any affective disorder and dysthymia but not anxiety disorder. These results call for more mechanistic research that explores the specific relations between childhood anxiety disorder and asthma and between affective disorder and other pediatric chronic illnesses.

Variations in Healthcare Access and Utilization Among Mexican Immigrants: The Role of Documentation Status

The objective of this study is to identify differences in healthcare access and utilization among Mexican immigrants by documentation status. Cross-sectional survey data are analyzed to identify differences in healthcare access and utilization across Mexican immigrant categories. Multivariable logistic regression and the Blinder-Oaxaca decomposition are used to parse out differences into observed and unobserved components. Mexican immigrants ages 18 and above who are immigrants of California households and responded to the 2007 California Health Interview Survey (2,600 documented and 1,038 undocumented immigrants). Undocumented immigrants from Mexico are 27% less likely to have a doctor visit in the previous year and 35% less likely to have a usual source of care compared to documented Mexican immigrants after controlling for confounding variables. Approximately 88% of these disparities can be attributed to predisposing, enabling and need determinants in our model. The remaining disparities are attributed to unobserved heterogeneity. This study shows that undocumented immigrants from Mexico are much less likely to have a physician visit in the previous year and a usual source of care compared to documented immigrants from Mexico. The recently approved Patient Protection and Affordable Care Act will not reduce these disparities unless undocumented immigrants are granted some form of legal status.

Use of Preventive Care Services Among Latino Subgroups

BACKGROUND Previous studies demonstrate a clear gap in access and receipt of preventive care between Latinos and non-Latino whites. Most of this work, however, pools Latinos together when they compare different racial and ethnic groups. There is currently no information about the consistency of preventive care utilization across major Latino subgroups. PURPOSE This study tests for three bundles of preventive care services to analyze the main determinants of adult preventive care receipt among the largest subgroups of U.S. Latinos and non-Latino whites. It also examines the contribution of observed and unobserved factors in explaining differences in the provision of preventive care services. METHODS The Medical Expenditure Panel Survey and the National Health Interview Survey from 2000 to 2006 were merged in 2009. The sample consisted of 28,781 Latinos and 78,979 non-Latino whites. This study compared disparities in the receipt of adult preventive care services and separately examined differences in the provision of the most cost-effective preventive services. Multivariate models adjust for confounding factors. The decomposition technique was used to parse out differences into observed and unobserved components. RESULTS Latinos of Mexican and Central/South American origin are much less likely to receive guideline-recommended preventive care services than non-Latino whites and other Latino subgroups. Larger disparities were observed for the most cost-effective preventive care services: smoking-cessation advice, colorectal cancer screening, and influenza vaccination. Observed factors accounted for a larger share of disparities across measures (33%-100%), with lack of health insurance coverage and not having a usual source of care as the largest and most consistent factors explaining disparities. CONCLUSIONS Health insurance coverage expansion and more integration of Latinos into primary care practices can substantially reduce disparities in the receipt of preventive care services. Preventive care initiatives should prioritize the availability of cost-effective services among Latinos of Mexican and Central/South American heritage.

Racial and Ethnic Disparities in Health Care Access and Utilization Under the Affordable Care Act.

Objective:To examine racial and ethnic disparities in health care access and utilization after the Affordable Care Act (ACA) health insurance mandate was fully implemented in 2014. Research Design:Using the 2011–2014 National Health Interview Survey, we examine changes in health care access and utilization for the nonelderly US adult population. Multivariate linear probability models are estimated to adjust for demographic and sociodemographic factors. Results:The implementation of the ACA (year indicator 2014) is associated with significant reductions in the probabilities of being uninsured (coef=−0.03, P<0.001), delaying any necessary care (coef=−0.03, P<0.001), forgoing any necessary care (coef=−0.02, P<0.001), and a significant increase in the probability of having any physician visits (coef=0.02, P<0.001), compared with the reference year 2011. Interaction terms between the 2014 year indicator and race/ethnicity demonstrate that uninsured rates decreased more substantially among non-Latino African Americans (African Americans) (coef=−0.04, P<0.001) and Latinos (coef=−0.03, P<0.001) compared with non-Latino whites (whites). Latinos were less likely than whites to delay (coef=−0.02, P<0.001) or forgo (coef=−0.02, P<0.001) any necessary care and were more likely to have physician visits (coef=0.03, P<0.005) in 2014. The association between year indicator of 2014 and the probability of having any emergency department visits is not significant. Conclusions:Health care access and insurance coverage are major factors that contributed to racial and ethnic disparities before the ACA implementation. Our results demonstrate that racial and ethnic disparities in access have been reduced significantly during the initial years of the ACA implementation that expanded access and mandated that individuals obtain health insurance.

Self-reliance, mental health need, and the use of mental healthcare among island Puerto Ricans.

This paper examines the relationship between self-reliance (preference to solve emotional problems on ones own) and 5 mental healthcare utilization outcomes for Puerto Ricans living in low-income areas. A random probability community sample of noninstitutionalized Puerto Ricans, ages 18–69, living in low-income areas of the island were selected and interviewed in 1992–93 and 1993–94. A series of logistic regression models tested the association between self-reliance and 5 mental health utilization measures, after adjusting for covariates measuring predisposing, enabling, need and barrier factors: any use of mental health services, any use of general health services for mental healthcare, any use of specialty care, use of psychotropic medications, and retention in mental healthcare. Self-reliance was found to be negatively associated with all 5 dependent service utilization measures. Those with a positive self-reliant attitude were 40% less likely to use care on any of the 5 outcome measures. An interaction was also observed between definite need for mental healthcare and having a self-reliant attitude when predicting mental health service use. Definite needers with a self-reliant attitude were 54%–58% less likely to use mental health services compared with definite needers who did not have a self-reliant attitude. Further, decreases in self-reliant attitude over the two data collection periods were associated with increases in mental health service use. Our findings suggest that self-reliance is a significant and robust predictor of mental healthcare utilization among Puerto Ricans living in low-income areas of the island.

Health Status of Mexican-Origin Persons: Do Proxy Measures of Acculturation Advance our Understanding of Health Disparities?

Objectives This paper compares select health status indicators between the U.S. and Mexico, and within the Mexican-origin population using proxy measures of acculturation. Methods Statistical data were abstracted and a Medline literature review conducted of English-language epidemiologic articles on Mexican-origin groups published during 1976–2005. Results U.S.-born Mexican-Americans have higher morbidity and mortality compared to Mexico-born immigrants. Mexico has lower healthcare resources, life expectancy, and circulatory system and cancer mortality rates, but similar infant immunization rates compared to the U.S. Along the U.S.-Mexico border, the population on the U.S. side has better health status than the Mexican side. The longer in the U.S., the more likely Mexican-born immigrants engage in behaviors that are not health promoting. Conclusions Researchers should consider SEP, community norms, behavioral risk and protective factors when studying Mexican-origin groups. It is not spendingtime in the U.S. that worsens health outcomes but rather changes in health promoting behaviors.

Use of health services by insurance status among children with asthma.

Objectives.It is well known that asthmatic children receiving Medicaid use the emergency department (ED) more frequently than otherwise-insured asthmatic children. However, the extent to which this difference is attributable to provider characteristics, medication use, access to primary care, and symptomatology is poorly understood. These factors were explored as independent predictors of health care utilization. Methods.Baseline data from a prospective cohort study of childhood asthma severity were used. Subjects were recruited from seven New England hospitals. Home interviews collected data on monthly symptoms, health care visits, insurance status, as well as sociodemographics and asthma-related risk factors (n = 804). Characteristics of providers’ practices, board certifications, and asthma specialty were obtained from Folio’s Medical Dictionaries for Connecticut and Massachusetts. Results.After adjusting for frequency of asthma-related primary care visits, primary provider practice type, use of asthma specialist, age, gender, medication use, and symptomatology, Medicaid children still used the ED more frequently for asthma services than privately insured children (RR, 1.7; 95% CI, 1.1, 2.5). In general, race/ethnicity did not modify the relationship between insurance status and health care use, except that black children receiving Medicaid were 90% (95% CI, 0.0, 0.7) less likely to have had ≥3 routine primary care visits for asthma in the previous year than black privately insured children. White children receiving Medicaid were 2.5 (95% CI, 1.0, 6.9) times more likely to use the ED for asthma than privately insured white children. Conclusions.The results suggest that enabling, structural, and need factors do not necessarily explain observed differences in pediatric asthma health care use by insurance status. Future investigation must explore other explanatory factors such as maternal attitudes and beliefs and patient-provider communication.

The effect of neonatal intensive care level and hospital volume on mortality of very low birth weight infants.

Objective:To determine the adjusted effect of hospital level of care and volume on mortality of very low birth weight (VLBW) infants in the state of California, where deregionalization of perinatal care has occurred. Research Design:Secondary data analysis of California maternal-infant hospital discharge data from 1997 to 2002 was performed. Logistic regression was used to evaluate the odds of mortality among VLBW infants by hospital level of neonatal intensive care and volume of VLBW deliveries, in the context of differences in antenatal and delivery factors by hospital site of delivery. Results:Both maternal and fetal antenatal risk profiles and delivery characteristics vary by hospital site of delivery. After risk adjustment, lower-level, lower-volume units were associated with a higher odds of mortality. The highest odds of mortality occurred in level-1 units with ≤10 VLBW deliveries per year (odds ratio, 1.69; 95% confidence interval, 1.43–1.99). In isolation, hospital volume, rather than level of care, had the greater effect. Conclusions:Although deregionalization of perinatal services may increase access to care for high-risk mothers and newborns, its impact on hospital volume may outweigh its potential benefit.
