Determinants of Usual Source of Care Disparities among African American and Caribbean Black Men: Findings from the national Survey of american life

Abstract

Purpose

The Aday-Andersen model was used as a framework for investigating the contribution of immigration status (i.e., nativity and acculturation), socioeconomic factors, health care access, health status, and health insurance to usual source of health care (USOC) in a nationally representative sample of African American (n5551) and Caribbean Black men (n51,217).

Methods

We used the 2001–2003 National Survey of American Life, a nationally representative household survey of non-institutionalized U.S. Blacks to conduct descriptive and logistic regression analyses.

Results

Older age, more health conditions, neighborhood medical clinic access, and health insurance were associated with higher odds of reporting a USOC. Odds were lower for men with lower-middle incomes and poorer mental health status. Having health insurance was associated with higher odds of reporting a USOC for African American men but lower odds among Caribbean Black men. Odds were higher in the presence of more health conditions for African American men than for Caribbean Black men.

Conclusions

Health care reform policies aimed solely at increasing health insurance may not uniformly eliminate USOC disparities disfavoring U.S. and foreign-born non-Hispanic Black men.

Men's health disparities have received increased attention in recent years as researchers attempt to uncover the causes of persistent gender inequities in life-expectancy and mortality from conditions amenable to medical intervention.1 Although the epidemiologic evidence is somewhat equivocal, men die sooner and more often than women from a number of chronic conditions.2 Gender differences in mortality from medically amenable conditions are most pronounced for non-Hispanic Black men.1 According to recent national estimates, non-Hispanic Black (NHB) men have a much higher cardiovascular disease death rate (422.8 per 100,000) than non-Hispanic White (NHW) males (306.6), NHB females (298.2), and NHW females (215.5 per 100,000).3 Non-Hispanic Black men also have a 33% higher death rate from all cancers combined,4 and death rates that exceed NHW men's from cancers detectable through preventive screening.4,5 More specifically, despite recent declines in lung cancer mortality among NHB men, this population experienced a higher percentage of lung cancer-related deaths between 2000 and 2006 than individuals from other race-sex groups.4,6 Prostate cancer also claims the lives of a disproportionately high number of NHB men, a disparity projected to increase significantly over the next 40 years.7

The causes of NHB men's markedly greater mortality reflect a host of biological, socioeconomic, and psychological factors,8,9 with a key contributor being the reduced likelihood in this population of seeking or obtaining timely medical interventions.10 Men in the U.S. generally make fewer health visits, are less likely to seek help for health problems, and obtain fewer preventive health screenings than women.1114 Yet NHB men attend fewer annual health visits, have poorer BP control, and obtain early-stage cancer screenings at lower rates than their NHW male counterparts.4,15,16

Having a usual source of health care (USOC) increases timely receipt of preventive screenings,1721 improves hypertension screening and care,22 and fosters informed decision-making about cancer screening.23 However, in the U.S., more men than women are uninsured24 and lack a usual provider or source of care (USOC),17,2530 despite the fact that women pay higher health insurance premiums.31 Non-Hispanic Black men are even less likely than NHW men to be insured or have a USOC.14,18 Yet few investigations report determinants of USOC among NHB men, and those that do limit their focus to socioeconomic or health insurance-related factors.25 The dearth of research examining a broader range of USOC determinants among NHB men is worsened by the fact that extant research concentrates on Black-White comparisons and lumps African American and Caribbean Black men into the same racial/ethnic category. Studies based on Black-White differences are limited in their capacity to identify subpopulations of NHB men who face the greatest USOC barriers or to inform the design of interventions that target culture-specific impediments to USOC. Comparing African American and Caribbean Black men helps clarify whether new health care policies directed at reducing health insurance and other socioeconomic barriers will uniformly improve USOC access for these groups. Such a comparison also allows for a more careful examination of the potential contribution made by immigrant or foreign-born status to USOC disparities among NHB men.

Although Caribbean Black men fare better than African American men across a number of mortality indicators,3234 they are less likely to report visiting physicians35 and are more likely to be uninsured.35 A recent cross-national investigation determined that even when foreign-born individuals are insured, they are still less likely than U.S.-born individuals to have a regular physician.36 The Personal Responsibility Work Opportunity Reconciliation Act (PRWORA), made law in 1996, created additional insurance-related USOC barriers for Caribbean Black men since it limits access to federally funded services such as Medicaid to legal immigrants who have resided in the U.S. for five or more years.37 Length of time in the U.S. is often used as a proxy indicator of acculturation or “the process by which immigrants adopt the attitudes, values, customs, beliefs, and behaviors of a new culture.”38[p.1342] Studies investigating factors contributing to lower mortality rates among racial/ethnic minority immigrants conclude that the so-called immigrant health advantage declines with longer time spent in the U.S.32,3942 Declines in immigrant health advantage are believed to be attributable partly to negative parts of acculturation, which include stress, loss of cultural identity, marginalization and isolation, and resource deprivation.43 On the other hand, longer time spent in the U.S. is associated with increased USOC access among older, Hispanic/ Latino immigrants.44

It is unclear whether length of time in the U.S. is associated with USOC among Caribbean Black men. Investigating the association between length of time in the U.S. and USOC among Caribbean Black men represents an initial step towards clarifying whether declines in immigrant health advantage are partially a consequence of health care system barriers. Identifying the degree to which immigrant status (nativity and acculturation), socioeconomic factors, and health insurance contribute to USOC disparities among Caribbean Black and African American men will help ensure that health care reform policies and programs are adequately tuned to distinct barriers faced by these populations. Recognizing this empirical need and the heterogeneity of these groups, our primary goals were: 1) to assess the relative contribution of immigrant status (i.e., nativity and acculturation), socioeconomic factors, and health insurance to African American and Caribbean Black men's USOC procurement; and (2) to determine whether health insurance equally facilitates USOC access among insured African American and Caribbean Black men.

Theoretical framework

We use the Aday-Andersen model45 to frame our assessment of USOC determinants.46 The Aday-Andersen model45 is the most frequently employed classification of health care utilization determinants. According to original versions of this model, health care utilization is determined by predisposing (e.g., gender, race, ethnicity, and educational attainment), enabling (e.g., income, employment, marital status, and health insurance), and need factors (e.g., the presence of established health conditions and mental health status). Researchers have revised the Aday-Andersen model to incorporate contextual factors,30,4749 including geographic region, neighborhood-level characteristics (e.g., urbanicity and the presence of a health care clinic/center within a neighborhood), and factors that specifically affect vulnerable populations such as nativity status.50 Usual source of health care is commonly characterized in the original and revised versions of the Aday-Andersen model as a predictor variable that enables uninhibited entry into the health care system. Building on revised versions of the Aday-Andersen model, we treat USOC as an outcome and assess the relative contribution of predisposing, enabling, and need factors hypothesized to affect health care access among U.S. and foreign-born NHB men.

Methods

Data and sampling

Data were obtained from the 2001 to 2003 National Survey of American Life (NSAL), a nationally representative face-to-face in-home survey of non-institutionalized African Americans, Caribbean Blacks, and NHWs aged 18 years and older.51 The NSAL was designed to investigate inter- and intra-group racial/ethnic differences in psychiatric disorders and impairment, help-seeking, and health services use. Multi-stage probability methods were used to select a sample of 3,570 African Americans, 1,621 Blacks of Caribbean descent (Caribbean Blacks), and 891 NHWs from households in areas where at least 10% of the population is Black. Individuals were classified as Caribbean Black if they self-reported as Black and either 1) of West Indian or Caribbean descent, 2) from a Caribbean area or country, or 3) related to parents or grandparents who were born in a Caribbean country. The response rate for the NSAL was 70.7% for the African American sample, 77.7% for Caribbean Blacks, 67.7% for NHW's, and 72.3% in the overall sample. For the purposes of the current study, we focused on the NSAL sample of African American (N51,217) and Caribbean Black men (N5551).

Dependent variable

Usual source of care was measured by responses to the question, “Is there one place or person you usually go to when you are sick or in need of medical advice?” (no USOC 5 0; has a USOC 5 1).

Independent variables

Predisposing determinants include race/ethnicity (African American, Caribbean Black), nativity status (U.S.-born vs. Foreign-born), geographic region (as defined by the Bureau of Census Department and Labor: Northeast, Midwest, South, and West), age (18–29 years, 30–44 years, 40–49 years, ≥60 years), education (high school graduate or less and some college), marital status (not married 5 0, married 5 1), and acculturation (number of years in the U.S. [≤5 years, 6–10 years, 11–20 years, 21 years or more]). Enabling determinants included employment status (not employed vs. currently unemployed), household income (<$20,000, $20,000–$29,999, $30,000–$49,999, $50,000–$79,999, ≤$80,000), and health insurance status (does not have 5 0; has insurance 5 1), and the availability of a neighborhood medical clinic (no 5 0, yes 5 1). Need determinants measured included the number of diagnosed health problems and mental health status (e.g., depressive symptomatology). The number of health problems were dichotomized (no health problems 5 0; 1 or more health problems 5 1) for the bivariate analyses and summed for our multivariate analyses. We used the 12-item version of the Center for Epidemiologic Studies Depression Scale (CES-D)52 administered in the NSAL survey to assess mental health status. Both long and shortened CES-D versions assess the presence of acute depressive symptoms and have been widely used and validated among a variety of racial/ethnic groups.53,54 For our bivariate models, individuals with scores below the population mean (8.15) were assigned a value of 0 and those above the population mean were assigned a value of 1. An overall CES-D score was computed (range 0–36) with higher scores indicating poorer mental health status (more depressive symptoms) which was used in the multivariate models.

Statistical analysis

Consistent with the Aday-Andersen model, we classified study characteristics into predisposing factors (nativity, number of years in the U.S., geographic region, race/ethnicity, age, education, marital status), enabling factors (employment, income, health insurance, neighborhood medical clinic access) and need factors (number of diagnosed health problems, mental health status). Simple (unadjusted) models testing the univariate associations between each of the study characteristics and USOC were conducted (see Table 1). We also compared mental health status (mean CES-D scores) and the mean number of diagnosed health problems by reported USOC. Next, we fit a series of bivariate models testing the association between study characteristics and USOC stratified by race/ethnicity (Table 2). This series of models included covariates for one population characteristic, race/ethnicity (African American vs. Caribbean Black), and the interaction between race/ethnicity and the population characteristic. The proportion having a USOC was computed from each of these regressions along with a test of racial/ethnic differences. The proportion for physical health (e.g., the number of diagnosed health problems) was predicted from the fitted model for a value of 0 and 1 or more. For mental health status (e.g., CES-D scores), the proportion was predicted from the fitted model for a value of 0 and for the mean value for the sample.

We then fit separate logistic regression models (Table 3) for predisposing, enabling, and need factors to predict the odds of having a USOC. A final model was then fit entering all factors simultaneously. We explored all possible two-way interactions between race/ethnicity, nativity, acculturation, and our enabling and need factors. Continuous variables were mean centered. Consistent with well-established procedures,55 we calculated odds ratios and 95% confidence intervals (CIs) for our interactions and main effects. In the tables provided, the number of respondents (n) represents the unweighted survey sample size, whereas the reported proportions have been weighted to produce estimates for the entire U.S. population. All analyses were conducted using the SVY commands of Stata 1056 with sample weights to adjust for sample selection, population size, and design effects. Statistical results were considered significant at the p,.05 level. This study was approved by the University of North Carolina Institutional Review Board.

Results

Demographic and lifestyle characteristics

Table 1 displays sociodemographic and lifestyle characteristics of the study participants and their association with reported USOC. Most participants were African American, U.S.-born, reported their education as high school or less, and had lived in the U.S. for 21 years or more.* Age was equally distributed across the sample (M 5 42 years). The sample had an equal number of married and unmarried participants. More men in the sample were currently employed than unemployed. Household incomes were fairly equally distributed with the fewest participants reporting incomes of $80,000 or more (11%). Most men in the sample had health insurance, neighborhood medical clinic access, and resided in the Southern region of the U.S.

Determinants of USOC

Bivariate results. The majority of the sample reported having a USOC (Table 1) and the proportions of African American and Caribbean Black men with a USOC were similar. Overall, more men who were older, married, unemployed, had some college education, and earned higher household incomes indicated having a USOC. A higher proportion of men with health insurance, a neighborhood medical clinic, and poorer physical health status (i.e., more diagnosed health problems) reported having a USOC. More men with better mental health status (i.e., lower mean CES-D scores) reported having a USOC. Associations between USOC and nativity status or length of time in the U.S. were non-significant.

Our stratified analyses revealed that education, geographic region, income, and physical health status were not significantly or uniformly associated with USOC among both groups (Table 2). Higher education, unemployment, health insurance, neighborhood medical clinic access, and better mental health status were only significantly associated with USOC among African American men. Regional differences emerged only for Caribbean Black men, who had a higher proportion of individuals reporting a USOC in the West than in the South, Midwest, and Northeast. A higher proportion of Caribbean Black men living in the West had a USOC than African American men residing in that region. For participants in the $30,000–$49,999 income and better physical health categories, fewer Caribbean Black men than African American men had a USOC.

Multivariate results (main effects)

Race/ethnicity, nativity status, or years in the U.S. were not statistically significant determinants of USOC (Table 3). However, in Model 1, where predisposing determinants were entered, men who were 50 years and older (OR53.45, 95% CI: 2.13, 5.61) and those age 40–49 (OR51.74, 95% CI: 1.21, 2.51) were more likely to report having a source of care than men who were 18 to 29 years old. Similarly, married men were more likely than unmarried men to report having a USOC (OR51.57; 95% CI: 1.08, 2.29). Men who reported their education as high school or less were less likely than men with some college to have a USOC (OR50.55; 95% CI: 0.38, 0.81). In Model 2, unemployed men were less likely to have a USOC than employed men (OR50.49, 95% CI: 0.31, 0.78). Men with incomes of less than $20,000 (OR50.38; 95% CI: 0.15, 0.95), and whose incomes were between $20,000 and $30,000 (OR50.29; 95% CI: 0.13, 0.61), were less likely to have a USOC than men in the highest income category. Men with health insurance were more likely than uninsured men to have a USOC (OR52.51; 95% CI: 1.72, 3.67). Neither geographic region nor neighborhood medical clinic availability was associated with USOC. When need determinants were explored (Model 3), men with more diagnosed problems were more likely to report a USOC (OR51.53; 95% CI: 1.29, 1.82). In contrast, men with poorer mental health status (higher CES-D scores) were less likely to report having a USOC (OR50.94; 95% CI: 0.91, 0.97). When the determinants were entered simultaneously (Model 4), the odds of reporting a USOC were higher for men aged 50 and older (OR51.83; 95% CI: 1.13, 2.97), who were insured (OR51.90; 95% CI: 1.28, 2.83), had a medical clinic in their neighborhood (OR51.40; 95% CI: 1.04, 1.90), and had more diagnosed health problems (OR51.35; 95% CI: 1.10, 1.66). Men with poor mental health status (higher CES-D scores) were also less likely to report having a USOC (OR50.96; 95% CI: 0.92, 0.99).

Multivariate results (interaction effects)

Although a main effect for race/ethnicity was not observed, we did find a significant interaction between this variable and health insurance status (p=.03) and the number of diagnosed health conditions (p=.03). In the absence of health insurance, Caribbean Black men had nearly three times greater odds of having a USOC than African American men had (OR=2.70, 95% CI: 0.78, 9.37). However, in the presence of health insurance, Caribbean Black men had slightly lower odds of having a USOC than African American men (OR=0.92, 95% CI: 0.36, 2.38). We also found that in the absence of diagnosed health problems (lower level of health need), Caribbean Black men had lower odds of having a USOC than African American men (OR=0.44, 95% CI: 0.19, 1.03). However, the odds of having a USOC increased much faster for Caribbean Black men than for African American men, with Caribbean Black men having three health problems being four times more likely to have a USOC (OR=4.02, 95% CI: 0.46, 30.91). None of the other interactions were significant.

Discussion

In light of NHB men's disproportionate mortality from medically amenable conditions, this investigation examined determinants of USOC among a nationally representative sample of African American and Caribbean Black men. Although previous studies have reported determinants of USOC, only one35 explicitly disentangled differences in the sources of USOC disparities between subpopulations of NHB men. Our study utilized the most recent nationally representative sample of Blacks in the diaspora to examine a broader range of USOC determinants than has been examined in previous studies and to assess the consistency of these associations between African American and Caribbean Black men. We focused specifically on ascertaining whether health insurance uniformly increased USOC access among African American and Caribbean Black men. We demonstrated that the association between this determinant and USOC differs for African American and Caribbean Black men in unexpected and important ways. Our findings contribute to the accumulating evidence documenting the modest effects of health insurance on health care access and thus hold the potential to inform policies and programs designed to reduce health care disparities among NHB men. Specifically, our findings indicate that health reform policies directed singularly at increasing health insurance access may have less of an impact on USOC procurement for Caribbean Black men than it may for African American men.

Predisposing determinants

Eighty percent of our sample indicated having a USOC, a figure similar to that reported in another nationally representative study29 and by the CDC.28 Generally, we found that enabling (e.g., income, employment, marital status and health insurance) and need factors (e.g., presence of established health conditions and mental health status) were the most significant determinants of USOC among African American and Caribbean Black men. Prior studies among the general population have reached similar conclusions.18,29 We learned that older African American and Caribbean Black men were more likely to report having a USOC. This finding likely reflects age-related differences in health insurance coverage. For example, men aged 65 and older are more likely to be covered by Medicare, which may increase the likelihood of having a USOC. Higher reports of USOC among older men might also reflect an increased concern with health monitoring produced by aging. Usual source of care may be less commonly reported by younger men because they are generally in better health and thus may see less need for routine health care. However, this perception can lead to delays in the detection of disease conditions that have a relatively early onset among Black men (e.g., prostate cancer). Encouraging younger NHB men to establish a USOC could improve uptake of medical care later in the life-course when monitoring health status is critical. While marital status initially increased the odds of having a USOC for both groups of men, we saw its effect diminished in the presence of other socioeconomic and need-related determinants. This change in significance was not surprising since married people generally also have more income and report better physical and mental health. Nonetheless, leveraging spouses as partners in interventions to reduce Black men's health care access disparities may prove to be a viable strategy. Initially, we observed that men with higher levels of education were more likely to have a USOC. However, this relationship was not sustained when enabling and need factors were jointly considered. Our bivariate analyses also revealed that this association held only for African American men. The higher baseline levels of education attainment among the general Caribbean Black population57 may explain our failure to detect the same association for men from this group. This finding might also mean that health care policies that solely address educational or other socioeconomic factors may have variable effects on African American and Caribbean Black men's health care access. Nativity status or length of time in the U.S. did not affect USOC, which could be attributed to the large proportion of U.S.-born and longer-term immigrant residents in the sample.

Enabling determinants

Surprisingly, being unemployed was associated with an increased likelihood of having a USOC. However, this association disappeared in our fully adjusted multivariate model and was limited to African American men in our bivariate models. We speculate that unemployed African American men factored in informal health care sources and emergency departments, which tend to be utilized more often as USOC sites among African Americans as a whole.58 Additionally, Caribbean Black men have higher employment rates than African American men,59 but rely more on informal employment sources and are limited by their immigrant status from participating in government-sponsored health insurance.35 These combined factors may have led to the more expected, albeit non-significant, association between employment and USOC for this group.

Given prior evidence,25 we were not surprised to find that higher incomes increased men's likelihood of having a USOC. We were, however, intrigued to learn that the odds of having a USOC were reduced most for men in the lower-middle income category. We offer that this group is in a Catch-22 situation since its members often occupy positions offering limited health care benefits but have incomes that exceed eligibility limits for government-sponsored programs. Although health insurance increased the overall odds of having a USOC, our interaction results suggest that this increase occurred only among African American men. In fact, we found that insured Caribbean Black men were less likely to have a USOC, which implies that unmeasured personal characteristics play a bigger role for this group when insurance barriers are minimized. Previous research indicates that many adults without a USOC prefer not to have one.29 Since the NSAL did not contain questions about health care attitudes or USOC preferences, we were unable to assess the potential effects of these factors. Future studies should consider the role played by these determinants in USOC disparities among these groups.

Having more proximal medical clinic access increased the odds of having a USOC in our sample. Our investigation reinforces the need to focus attention on reducing structural health care access barriers among Black men, which might mitigate the impact of attitudinal factors (e.g., medical mistrust) on their health services use. We observed an initial association between geographic region and USOC suggesting access is better in the West for Caribbean Black men and lower for this same group in the South. Since our western region sample of Caribbean Black men was relatively small, it is difficult to draw any meaningful conclusions about this finding. However, we point to other research documenting less USOC among adults in the South29 to support our finding. When we examined regional (geographic) differences in USOC access in the overall sample, we found no differences.

Need determinants

Possibly because poor health leads them to seek regular medical assistance, men with more health conditions were more likely to have a USOC. However, compared with African American men, Caribbean Black men seem to be motivated more by pressing health concerns to secure a USOC. This response is consistent with more traditional masculine help-seeking9 and implies the need to emphasize the development of targeted primary prevention awareness among Caribbean Black men. In contrast with previous findings27 and with what was found for general health, men who reported more depressive symptoms were less likely to have a USOC. Using psychiatric diagnosis and other indicators of mental illness and mental health, future prospective studies can determine whether poor mental health interferes with securing a USOC, or whether having a USOC reflects better coping and, as a result, better mental health, or whether having a USOC promotes diagnosis and treatment of mental illness. Even so, our finding highlights the importance of including mental health promotion as a core component of efforts to improve Black men's access to medical care.

Limitations and strengths

Our study has some limitations. First, the question we used to assess USOC asked individuals if they had a regular place or person for health care. This strategy limited our ability to disaggregate effects for determinants associated with having a USOC from those associated with having a usual person or provider. Disentangling these effects may be important since others have found that having a regular doctor is more important in the receipt of preventative health care services than having a regular site.60 Since we did not account for health insurance type, we are unable to determine if the differences we observed between African American and Caribbean Black men are related to this factor. Indeed, immigrants are less likely to be have employee-sponsored insurance61 and have limited access to publicly funded programs because of the PRWORA.37 Future studies should determine if the associations we observed persist when controlling for health insurance type. Similarly to previous studies, we also used length of time in the U.S. as a proxy for acculturation. Using this static measure may have limited our ability to fully assess the role played by other factors linked to the acculturative processes (e.g., stress, isolation, resource deprivation). Furthermore, we are limited by the use of self-reported, cross-sectional data which may have introduced bias and minimized our ability to make causal inferences.

Nonetheless, our study has notable strengths. It is one of few nationally representative studies addressing determinants of USOC among African American and Caribbean Black men. The NSAL is the most recent national survey on the Black Diaspora. Thus, we are able to offer more reliable estimates of USOC determinants for African American and Caribbean Black men. We also extend previous research on USOC among Black men by examining the role played by other non-economic factors, which will be important to address in future policy and health care interventions designed to eliminate access disparities among this group.

Identifying USOC determinants is an important step towards producing viable health care reform strategies for vulnerable populations of men. Our study contributes to these efforts by documenting the relative effects of predisposing, enabling, and need factors on African American and Caribbean Black men's USOC procurement.

Footnotes

*The sample we are analyzing is 68.41% (N=1,217) African American men and 31.59% (N=562) Caribbean Black men. Because of unequal probability of selection of participants the race/ethnicity distribution of our sample differs from the distribution of the general population. To correct for this, we adjust our estimates by using sampling weights and allows us to estimate the race distribution in the general population that we would have if our sample was selected as a simple random sample (SRS). The weighted estimates of 93% African American and 7% Caribbean Black men seen on Table 1 refer to the race distribution of the general population of African American and Caribbean Black men, not the distribution of our sample. We have used the sampling weights to compute all estimates in our paper so that the results are relevant to the general population of African American and Caribbean Black men rather than be limited to the sample population.
