Gilbert LR, Tawiah NA, Adepoju OE. Exploring racial and secondary substance use differences in route of administration of opioid drugs: Analysis of the 2015-2019 treatment admission data. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2024; 162:209365. [PMID: 38626850 DOI: 10.1016/j.josat.2024.209365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 03/08/2024] [Accepted: 04/07/2024] [Indexed: 05/13/2024]
Abstract
INTRODUCTION The opioid crisis continues to evolve with increasing opioid-related overdose deaths among under-represented minorities. A better understanding of substance use differences in the route of administration for people using heroin and other opioids can lead to targeted strategies and interventions. METHODS Using the 2015-2019 Treatment Episode Data Set - Admissions (TEDS-A), a multinomial logistic regression model examined the relationship between race/ethnicity and secondary substance use with route of administration in a subset of 591,078 admissions. RESULTS For individuals reporting heroin as their primary substance, minoritized clients were both more likely to smoke (NH Blacks RR: 2.28, 95 % CI 2.16-2.41; Hispanic RR: 1.80, 95 % CI: 1.74, 1.87; Other RR: 2.09, 95 % CI: 2.00, 2.20) or inhale heroin (Hispanic RR: 1.82, 95 % CI 1.78-1.85; Other RR: 1.30, 95 % CI 1.25, 1.34) compared to non-Hispanic (NH) Whites. NH Black clients were nearly seven and a half times more likely to report inhaling (RR: 7.45, 95 % CI 7.28, 7.62) heroin over injecting it. Clients were more likely to smoke heroin compared to injection if they reported secondary drug use of methamphetamines (RR: 2.28, 95 % CI 2.21, 2.35) and other opioids (RR: 1.21, 95 % CI 1.15, 1.28). For clients reporting other opioids as their primary substance, Hispanic (RR: 1.33, 95 % CI 1.19, 1.47) and other racial/ethnic minority clients (RR: 2.50, 95 % CI 2.23, 2.79) were more likely to smoke opioids vs take it orally compared to their NH White counterparts. Individuals who reported methamphetamine use as a secondary substance were significantly more than three times as likely to smoke (RR: 3.07, 95 % CI 2.74, 3.45) or inject (RR: 3.36, 95 % CI 3.17, 3.57) compared to orally ingesting opioids, while those who reported cocaine or crack cocaine use were more than twice as likely to inject (RR: 2.22, 95 % CI 2.09-2.36) opioids than taking them orally. CONCLUSION Findings demonstrate significant racial and ethnic differences in the route of administration. This work expands on the understanding of the complex nature of polysubstance use in the evolving opioid crisis and the secondary substance use of clients on routes of administration of opioids and heroin, highlighting the need for tailored interventions to address the treatment needs of under-represented minorities.

DRUG AND ALCOHOL DEPENDENCE REPORTS 2024; 10:100217. [PMID: 38332901 PMCID: PMC10850106 DOI: 10.1016/j.dadr.2024.100217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/01/2024] [Accepted: 01/02/2024] [Indexed: 02/10/2024]
Abstract
Background The age of people who use illicit opioids has increased, with a clinical picture of accelerated ageing. The study aimed to determine, stratified by age: 1. The circumstances and characteristics of heroin-related toxicity deaths in Australia, 2020-2022; 2. The toxicological profile and autopsy findings; 3. The proportion of cases in which blood 6-acetyl morphine (6AM) was detected, as a measure of survival time. Methods Retrospective study of 610 cases of fatal heroin-related drug toxicity in Australia, 2020-2022. Cases were stratified as: <30 years, 30-39 years, 40-49 years, ≥50 years. Results Compared to the youngest group, those aged ≥50 years were more likely to have a history of chronic pain (12.4 v 3.3 %), to have their death attributed to combined drug toxicity/disease (20.1 v 3.3 %), and to have evidence of a sudden collapse (21.3 v 11.1 %). There were no differences in free morphine concentrations or glucuronide concentrations. Compared to the youngest group, however, the two older groups were significantly more likely to have 6AM present in blood, a proxy measure of a shorter survival time (52.0, 55.2 v 34.5 %). Compared to the youngest group, cases aged ≥50 years were more likely to be diagnosed with cardiomegaly (44.0 v 16.7 %), coronary artery disease (46.0 v 15.0 %), emphysema (35.0 v 5.1 %), hepatic steatosis (15.4 v 3.4 %), hepatic fibrosis (17.6 v 3.4 %), and cirrhosis (19.8 v 0.0 %). Conclusions Older cases of heroin overdose had more extensive heart, lung, and liver disease, and appeared more likely to have shorter survival times.

Abstract
AIMS To provide an overview of research literature on ageing and older people who use illicit opioids and stimulants by documenting the conceptual frameworks used and content areas that have been investigated. METHODS We conducted a scoping review of literature relating to ageing and older people who use illicit stimulants and opioids, defining 'older' as 40 years and above. Primary studies, secondary studies and editorials were included. Searches were conducted in PubMed and Embase in July 2020 and March 2021; the Cochrane library was searched in November 2021. Charted data included methodological details, any conceptual frameworks explicitly applied by authors and the content areas that were the focus of the publication. We developed a hierarchy of content areas and mapped this to provide a visual guide to the research area. RESULTS Of the 164 publications included in this review, only 16 explicitly applied a conceptual framework. Seven core content areas were identified, with most publications contributing to multiple content areas: acknowledgement of drug use among older people (n = 64), health status (n = 129), health services (n = 109), drug use practices and patterns (n = 84), social environments (n = 74), the criminal legal system (n = 28) and quality of life (n = 15). CONCLUSIONS The literature regarding older people who use illicit drugs remains under-theorized. Conceptual frameworks are rarely applied and few have been purposely adapted to this population. Health status and health services access and use are among the most frequently researched topics in this area.

[PMID: 35430465 DOI: 10.1016/j.socscimed.2022.114971] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Revised: 03/12/2022] [Accepted: 04/07/2022] [Indexed: 01/03/2023]
Abstract
This study aims to fill three knowledge gaps: (1) unclear role of ecological factors in shaping older adults' risk of opioid use disorder (OUD), (2) a lack of longitudinal perspective in OUD research among older adults, and (3) underexplored racial/ethnic differences in the determinants of OUD in older populations. This study estimates the effects of county-level social isolation, concentrated disadvantage, and income inequality on older adults' risk of OUD using longitudinal data analysis. We merged the 2013-2018 Medicare population (aged 65+) data to the American Community Survey 5-year county-level estimates to create a person-year dataset (N = 47,291,217 person-years) and used conditional logit fixed-effects modeling to test whether changes in individual- and county-level covariates alter older adults' risk of OUD. Moreover, we conducted race/ethnicity-specific models to compare how these associations vary across racial/ethnic groups. At the county-level, a one-unit increase in social isolation (mean = -0.197, SD = 0.511) increased the risk of OUD by 5.5 percent (OR = 1.055; 95% CI = [1.018, 1.094]) and a one-percentage-point increase in the working population employed in primary industry decreases the risk of OUD by 1 percent (OR = 0.990; 95% CI = [0.985, 0.996]). At the individual-level, increases in the Medicare Hierarchical Condition Categories risk score, physical comorbidity, and mental comorbidity all elevate the risk of OUD. The relationship between county-level social isolation and OUD is driven by non-Hispanic whites, while Hispanic beneficiaries are less sensitive to the changes in county-level factors than any other racial ethnic groups. Between 2013 and 2018, US older adults' risk of OUD was associated with both ecological and individual factors, which carries implications for intervention. Further research is needed to understand why associations of individual factors with OUD are comparable across racial/ethnic groups, but county-level social isolation is only associated with OUD among non-Hispanic white beneficiaries.

Identification of Morphine and Heroin-Treatment in Mice Using Metabonomics. Metabolites 2021; 11:metabo11090607.

Abstract
Although heroin and morphine are structural analogues and morphine is a metabolite of heroin, it is not known how the effect of each substance on metabolites in vivo differs. Heroin and morphine were administered to C57BL/6J mice in increasing doses from 2 to 25 and 3 to 9 mg kg−1 (twice a day, i.p.), respectively, for 20 days. The animals underwent withdrawal for 5 days and were readministered the drugs after 10 days. Serum and urine analytes were profiled using gas chromatography-mass spectrometry (GC-MS), and metabolic patterns were evaluated based on metabonomics data. Metabonomics data showed that heroin administration changed metabolic pattern, and heroin withdrawal did not quickly restore it to baseline levels. A relapse of heroin exposure changed metabolic pattern again. In contrast, although the administration of morphine changed metabolic pattern, whether from morphine withdrawal or relapse, metabolic pattern was similar to control levels. The analysis of metabolites showed that both heroin and morphine interfered with lipid metabolism, the tricarboxylic acid (TCA) cycle and amino acid metabolism. In addition, both heroin and morphine increased the levels of 3-hydroxybutyric acid and citric acid but decreased the serum levels of 2-ketoglutaric acid and tryptophan. Moreover, heroin and morphine reduced the levels of aconitic acid, cysteine, glycine, and oxalic acid in urine. The results show 3-Hydroxybutyric acid, tryptophan, citric acid and 2-ketoglutaric acid can be used as potential markers of opiate abuse in serum, while oxalic acid, aconitic acid, cysteine, and glycine can be used as potential markers in urine.

Abstract
OBJECTIVE Analyze 10-year trends in opioid use disorder with heroin (OUD-H) among older persons and to compare those with typical-onset (age <30 years) to those with late (age 30+) onset. DESIGN Naturalistic observation using the most recent (2008-2017) Treatment Episode Data Set-Admissions (TEDS-A). SETTING Admission records in TEDS-A come from all public and private U.S. programs for substance use disorder treatment receiving public funding. PARTICIPANTS U.S. adults aged 55 years and older entering treatment for the first time between 2008 and 2017 to treat OUD-H. MEASUREMENTS Admission trends, demographics, substance use history. RESULTS The number of older adults who entered treatment for OUD-H nearly tripled between 2007 and 2017. Compared to those with typical-onset (before age 30), those with late-onset heroin use were more likely to be white, female, more highly educated, and rural. Older adults with late-onset were more likely to be referred to treatment by an employer and less likely to be referred by the criminal justice system. Those with late-onset were more likely to use heroin more frequently but less likely to inject heroin than those with typical-onset. Those with typical onset were more likely to receive medication for addiction treatment than those with late-onset. CONCLUSION Late-onset heroin use is increasing among older U.S. adults. Research is needed to understand the unique needs of this population better. As this population grows, geriatric psychiatrists may be increasingly called upon to provide specialized care to people with late-onset OUD-H.

Abstract
Antisocial personality disorder is a risk factor for opioid use. There is a dearth of research which examines self-control and moral disengagement as potential mediators of this relationship. This study utilized data from the Pathways to Desistance study in analyses. Generalized structural equation modeling was utilized to test for mediation of the relationship between antisocial personality disorder and opioid use. Bootstrapped standard errors were computed so that a Clogg Z test could be estimated to determine if identified mediation effects significantly differed. Results indicated that a likely diagnosis of antisocial personality disorder increased risk for opioid use. Inclusion of moral disengagement and self-control into the model resulted in attenuation of this effect to non-significance and reduced the magnitude of the effect by around 45%. The contribution of both constructs to the total indirect effect did not significantly differ and only the total indirect effect was significant.

Abstract
One of the 12 Grand Challenges facing contemporary social work is to close the health gap experienced by those in historically marginalized communities (Uehara et al., 2013). As social workers, we seek to understand the individual, interpersonal, social, and environmental factors along with the structural inequities leading to initiation and continuation of substance misuse. We are constantly contextualizing the circumstances under which substance misuse occurs, as well as contextualizing our approaches to addressing this issue from both a public health and social justice perspective. In order to adequately meet this challenge, considerably more research-based knowledge on the substance use treatment needs and preferences of America's largest ethnic/cultural group, Latinx, is needed. This brief report outlines current challenges associated with substance use research focusing on active Latinx heroin users living in a border state in a time of rapidly evolving social policy related to immigration, substance regulation, and public health.

Abstract
BACKGROUND It is hypothesized that (a) self-perceived oral symptoms (OSs) are worse in intravenous heroin addicts (IHA) than controls; and (b) clinical periodontal inflammatory parameters (plaque index [PI], bleeding on probing [BOP], PD and clinical attachment loss [AL]), number of missing teeth (MT), and radiographic marginal bone loss (MBL) are higher in IHA compared with controls. The aim was to compare the self-perceived OSs and periodontal parameters among young IHA and controls. METHODS Sociodemographic data, self-perceived OSs and duration and daily frequency of intravenous heroin use was gathered using a structured questionnaire. Full-mouth PI, BOP, PD, and clinical AL were measured, and number of MT were recorded. Mesial and distal MBL on all teeth was measured on digital radiographs. Odds ratios (OR) with 95% confidence intervals (CI) were computed for self-perceived OSs and periodontal parameters were assessed using the Mann Whitney U-test and logistic regression analysis. Sample-size was estimated, and level of significance was set at P < 0.05. RESULTS OR (95% CI) for self-perceived loose teeth (P < 0.001), pain in teeth (P < 0.001), dry mouth (P < 0.001), burning sensation in mouth (P < 0.001), bleeding gums (P < 0.001) and pain during chewing (P < 0.001) were significantly higher in the test than control group. Number of MT (P < 0.05), PI (P < 0.05), clinical AL (P < 0.05), and mesial (P < 0.05) and distal (P < 0.05) MBL were statistically significantly higher among individuals in the test group compared with the control group. CONCLUSION Self-perceived OSs and periodontal inflammatory parameters were worse in IHA than controls.

Abstract
BACKGROUND Heroin use is a public health concern in the United States. Despite the unique etiology and patterns of heroin use among U.S. Latinos, long-term heroin trajectories and health consequences among Latinos are not well understood. This study aims to document the distinct heroin use trajectories for a group of street-recruited (non-treatment), young adult Mexican American men living in a disadvantaged community who were affiliated with gangs during their youth. METHODS One-time interviews conducted between 2009-2012 in San Antonio, TX collected retrospective data from a sample of 212 Mexican American young adult men who reported using heroin at least once. Group-based trajectory modeling was applied to determine discrete developmental trajectories of heroin use. ANOVA, Chi square tests, and multinomial logistic regression examined current (past year) social and health indicators among each trajectory group. RESULTS Five discrete heroin trajectories groups were identified: low use (n = 65); late accelerating (n = 31); early decelerating (n = 26); late decelerating (n = 38); and stably high (n = 52). Varying social and health consequences were found among the trajectory groups. CONCLUSION This study describes the unique heroin use trajectories and social and health outcomes among a high-risk subgroup of Mexican American men. The findings suggest that early intervention and intervention available in easy to access non-treatment spaces may be especially useful for groups of people who use relatively less heroin.

Abstract
Hepatitis C virus (HCV) in the U.S. has tripled in the prior five years, and injecting drug use is the primary risk for HCV, with up to 90% of older and former people who inject drugs (PWIDs) testing positive. Laboratory testing of HCV for any PWIDs is the gold standard, however many PWIDs lack access to health treatment or services. Identifying risks of HCV via a data science approach would aid community health workers (CHW) to rapidly link those most at risk of infection with treatment. This study employed a data-science approach to determine the strongest risk factors of HCV in a sample of Mexican-Americans WIDs n = 221 (96 negative/125 positive). Data included 238 demographic and psychosocial predictors. A Random Forest machine learning algorithm demonstrated significant prediction improvement over baseline no information rate comparison. Strongest risks for positive HCV included sharing drug-use equipment and younger age at first heroin use; receiving drug-education during incarceration was protective. A ROC curve fit to the prediction yielded an area under the curve of 0.77. Predictive variables of HCV in the present analysis can be obtained via screening by CHW. Identification of patients most at risk of HCV within community settings can maximize treatment utilization.

Abstract
The influence of the family is not well understood as it relates to drug use behaviors of Hispanic male adults. We examined the family's influence on drug use behavior, as perceived by Hispanic men who use heroin. One-time qualitative interviews were conducted with 21 current and former heroin users who participated in a larger study on long-term heroin use in Mexican-American men. Data were analyzed using a thematic analysis approach. Three main themes emerged: family as a supportive environment for heroin use; heroin as a family legacy; and, the family's strategies for helping to stop using heroin. A sub-theme emerged on the paradox of family involvement, which spanned the three main themes. This research lays a foundation for future work to disentangle the risks and benefits of family involvement to inform culturally-centered therapies and cultural adaptations to traditional therapeutic approaches with Mexican-American men who abuse drugs.

Abstract
Abstract Minority status is associated with mental and physical morbidity, substance dependence, and poor outcomes. To compare characteristics and treatment outcomes between patients from two minority groups in Israel (Christians and Muslims) and patients from the majority population (Jews) in methadone maintenance treatment (MMT), we prospectively studied all patients admitted to our clinic between 1993 and 2012 and followed up until 2013; 655 Jews, 67 Christians, and 37 Muslims. Christian patients differed from Jews and Muslims by younger age at admission to MMT, greater prevalence of drug injectors, and a higher proportion of Hepatitis-C and HIV sera positive. Muslims had comparatively less education and a lower proportion of females. The three groups had similar rates of one-year retention (75.9%) and opiate abstinence (68.1%). They also did not differ in long-term retention (up to 20 years): Muslims 5.5 years (95%CI 3.6-7.4), Christians 7.5 years (95%CI 6-9.1), and Jews 7.6 years (95%CI 7-8.2, p = .3). The Hepatitis-C incidence, however, was higher among the 21 admitted Hepatitis-C seronegative minorities (5.0/100 person years) than the 207 Hepatitis-C seronegative non-minority patients (1.7/100 person years, p=0.03). All groups had good treatment outcomes, except for Hepatitis-C seroconversion, which necessitates a specific preventive intervention among the minority groups.

Abstract
INTRODUCTION Adverse childhood experiences are associated with the development of substance use disorders. With opioid use disorder, a growing concern in the United States, we were interested in examining the relationship between adverse experiences and three landmarks of opioid use: age of opioid initiation, injection drug use, and lifetime overdose. METHODS Between May and December 2015, we interviewed consecutive persons seeking inpatient opioid detoxification. Participants were asked about age of opioid initiation, last month injection drug use, and lifetime history of overdose, and completed the ten-item Adverse Childhood Experience (ACE) questionnaire. RESULTS Participants (n=457) averaged 32.2 (±8.64) years of age, 71.3% were male, and 82.5% were non-Hispanic White. The mean score on the ACE scale was 3.64 (±2.75). Mean age at time of initiating opioid use was 21.7 (±7.1) years, 68.7% had injected drugs within the past month, and 39.0% had overdosed. After adjusting for age, gender, and ethnicity, the ACE score was inversely associated with age of initiating opioid use (b=-0.50, 95% CI -0.70; -0.29, p<.001), and positively associated with recent injection drug use (OR=1.11, 95% CI 1.02; 1.20, p=0.014) and the likelihood of experiencing an overdose (OR=1.10, 95% CI 1.02; 1.20, p=0.015) in a graded dose response manner. CONCLUSION Greater adverse childhood experiences are associated with three landmarks of opioid use risk. ACE screening may be useful in identifying high-risk subsets of opioid-using populations.

Abstract
Understanding the effect of cultural values on depression and how social networks influence these relationships may be important in the treatment of substance-using, Mexican American populations. Latino cultural values, familismo, personalismo, fatalismo, and machismo, may be associated with depression among Latinos. The current study identified the association of traditional Latino values on depressive symptomatology among a sample of Mexican American heroin injectors. A cross-sectional research design and field-intensive outreach methodology were utilized to recruit 227 Mexican American men. Participants were categorized into depressed and nondepressed groups. Relations among cultural values and depression were examined using logistic regression. Findings indicate that drug-using men with higher familismo and fatalismo scores are protected against depressive symptomatology. Relations between familismo and depression seem to be moderated by having a drug use network. In addition, findings reveal that age is inversely related to depressive symptomatology. Young Mexican American heroin users who do not ascribe to traditional Latino values may be highly associated with depression and therefore more vulnerable to riskier drug use behaviors. Moreover, drug-using social networks may affect the protective nature of certain cultural values. Further research is needed to identify whether culturally tailored treatments can cultivate these values while simultaneously undermining the effect of substance-using social networks in order to reduce depression symptoms among this group of high-risk substance users.

Abstract
Recovery High Schools (RHSs) have been among the continuum of care for adolescents experiencing addiction since 1979 (Moberg & Finch, 2008). Outcome studies for RHSs are limited, and even less is known about RHS engagement of Hispanics. RHS students are overwhelmingly middle-class non-Hispanic White students with prior formal treatment (Moberg & Finch, 2008). Hispanic youth are more likely to live in discordant low-income ethnic enclaves, placing them at high risk for addictive disorders (Torres, Kaplan, & Valdez, 2011). The individualized approach of RHSs could make them a culturally relevant continuing care intervention. This paper reviews the literature to explore the use of RHSs by Hispanics.

Abstract
OBJECTIVE This study examines patterns of multimorbidity among elderly male inmates across four domains of health (chronic medical conditions, drug- and alcohol-related diseases, impairments, and mental and behavioral health) to understand the complex health care needs of this growing population. METHOD We use the 2004 Survey of Inmates in State Correctional Facilities and Latent Class Regression Analysis to examine 22 health problems among 1,026 men aged 50 and older. RESULTS There are four groups of elderly male inmates: (a) relatively healthy (45.1%), (b) substance users with behavioral health issues (23.4%), (c) chronic unhealthy with impairments and violence/injury (23.6%), and (d) very unhealthy across all domains (7.9%). These groups have unique sociodemographic background and incarceration history characteristics. CONCLUSION This study demonstrates the complexity of health for elderly inmates. Prison health should continue to be monitored to aid correctional and community health programs in understanding clinical risks, exposures, and health care needs for this population.

Abstract
OBJECTIVE To examine the applicability of the "maturing out" theory to a sample of aging Mexican American men who are long-term heroin injectors. METHOD Ethnographic data were collected as part of a cross-sectional study of aging Mexican American heroin users in Houston with 20 current heroin users. RESULTS Findings indicate that dysfunctions that emerge in the heroin lifestyle lead not to cessation but rather to "maturing in," a specific process of social readjustment that returns the heroin user to a stable maintenance pattern of use instead of a recovery phase. This process of paradoxical maturing out can be attributed to the unconditional social support provided to the heroin user by family, peers, and the tecato subculture embedded in Mexican American communities. DISCUSSION Results highlight the implications for the intersection of heroin-related conditions, natural age-related impairments, and cognitive functioning that make this population increasingly susceptible to adverse health consequences.

Abstract
Drug use among older adults is a growing concern, particularly for the burgeoning Hispanic population. Older adults seeking drug treatment will double over the next decade to almost 6 million. Cultural factors influence drug use, and more specifically, Hispanic cultural values influence heroin use. This study explored Mexican-American injection drug users' adherence to traditional Hispanic cultural values and their impact on cessation. Ethnographic interviews endorsed contextualized influences of values on heroin use. Cultural values functioned dichotomously, influencing both initiation and cessation. Understanding the impact of cultural values on substance abuse is critical given the changing demographics in American society.

Abstract
This article describes social capital in a cohort of 227 Mexican American men who are long-term injection heroin users. Social capital scores for current and former users were similar, suggesting equal absolute values of capital, but associated with illicit activities in current users and with cessation efforts in former users. Stable drug-using relationships provided high negative capital, whereas conventional relationships provided positive capital. Thus, social capital functions dichotomously in positive and negative contextualized roles. This study provides an alternative understanding of the dynamic interactions between individuals, environment, and drug abuse and can inform prevention and treatment interventions for an important demographic group.

Abstract
BACKGROUND This study explores the spatial accessibility of outpatient drug treatment facilities and the potential relationship with drug use-related outcomes among Mexican American heroin users. METHODS Secondary data on 219 current and former heroin-injecting Mexican American men aged 45 and older were drawn from a research study in Houston, Texas. We used geographic information systems (GIS) to derive two spatial accessibility measures: distance from one's place of residence to the closest drug treatment facility (in minutes); and the number of facilities within a 10-minute driving distance from one's place of residence. Exploratory logistic regression analyses examined the association between the spatial accessibility of drug treatment facilities and several drug use-related outcomes: internal locus of control (LOC); perceived chances and worries of injecting in the next six months; treatment utilization; and location of last heroin purchase. RESULTS Participants with greater spatial access to treatment programs were more likely to report a higher chance of injecting in the near future. However, while current heroin users were more worried about injecting in the next six months, greater spatial access to treatment programs seemed to have a buffering effect. Finally, those who lived closer to a treatment programs were more likely to have last purchased heroin inside the neighborhood versus outside the neighborhood. Spatial accessibility was not associated with internal LOC or treatment utilization. CONCLUSION The findings showed that the presence of outpatient treatment facilities-particularly services in Spanish-may influence perceived risk of future heroin use and purchasing behaviors among Mexican American men. Implications for future spatially-informed drug use research and the planning of culturally and linguistically responsive drug treatment programs are discussed.

Abstract
Objectives Self-rated health (SRH) is a commonly used measure in surveys to assess general health status or health-related quality of life. Differences have been detected in how different ethnic groups and nationalities interpret the SRH measure and assess their health. This review summarizes the research conducted on SRH within and between ethnic groups, with a focus on indigenous groups. Study design and methods A search of published academic literature on SRH and ethnicity, including a comprehensive review of all relevant indigenous research, was conducted using PubMed and summarized. Results A wide variety of research on SRH within ethnic groups has been undertaken. SRH typically serves as an outcome measure. Minority respondents generally rated their health worse than the dominant population. Numerous culturally-specific determinants of SRH have been identified. Cross-national and cross-ethnicity comparisons of the associations of SRH have been conducted to assess the validity of SRH. While SRH is a valid measure within a variety of ethnicities, differences in how SRH is assessed by ethnicities have been detected. Research in indigenous groups remains generally under-represented in the SRH literature. Conclusions These results suggest that different ethnic groups and nationalities vary in SRH evaluations, interpretation of the SRH measure, and referents employed in rating health. To effectively assess and redress health disparities and establish culturally-relevant and effective health interventions, a greater understanding of SRH is required, particularly among indigenous groups, in which little research has been conducted.
