Trends in alcohol-related mortality among New Mexico's American Indians, Hispanics, and non-Hispanic whites

Wanting and Getting Help for Substance Problems on Both Sides of the US-Mexico Border

The US-Mexico border presents potential cultural and logistic barriers to obtaining substance abuse treatment. We compare the prevalence and correlates of wanting and getting help between border and non-border residents in both the US and Mexico. Data come from the 2011 to 2012 US-Mexico Study on Alcohol and Related Conditions which surveyed 3214 border and 1582 non-border residents in the US and Mexico. Multivariate logistic regressions estimate the effect of border residence on desire for and receipt of help. In both countries, border substance users were about half as likely as nonborder substance users to have wanted or obtained any kind of help, independent of predisposing, need and enabling factors, including migration status. Among those desiring help, however, about half had obtained it, both on and off the border in both countries. While substantial proportions of those who need help do not get it either on or off the border, lower motivation for treatment may be more important than access in explaining border/non-border differences. Future research should investigate whether there are border-specific barriers to wanting help, and how to minimize them.

A randomized controlled trial of guided self-change with minority adolescents

OBJECTIVE

Adolescent substance use and abuse is a pressing public health problem and is strongly related to interpersonal aggression. Such problems disproportionately impact minority youth, who have limited access to evidence-based interventions such as ecological family therapies, brief motivational interventions (BMIs), and cognitive behavioral therapies (CBTs). With a predominantly minority sample, our objective was to rigorously evaluate the efficacy of a school-based BMI/CBT, Guided Self-Change (GSC), for addressing substance use and aggressive behavior.

METHOD

We conducted a school-based randomized, controlled trial with 514 high school students (mean age 16.24 years, 41% female, 80% minority) reporting using substances and perpetrating aggression. We used structural equation modeling to compare participants randomly assigned to receive GSC or standard care (SC; education/assessment/referral-only) at posttreatment and at 3 and 6 months posttreatment on alcohol use, drug use, and interpersonal aggression outcomes as assessed by the Timeline Follow-Back.

RESULTS

Compared with SC participants, GSC participants showed significant reductions (p < .05) in total number of alcohol use days (Cohen's d = 0.45 at posttreatment and 0.20 at 3 months posttreatment), drug use days (Cohen's d = 0.22 at posttreatment and 0.20 at 3 months posttreatment), and aggressive behavior incidents (Cohen's d = 0.23 at posttreatment). Moreover, treatment effects did not vary by gender or ethnicity.

CONCLUSIONS

With minority youth experiencing mild to moderate problems with substance use and aggressive behavior, GSC holds promise as an early intervention approach that can be implemented with success in schools.

Association between alcohol screening scores and mortality in black, Hispanic, and white male veterans

BACKGROUND

Scores on the Alcohol Use Disorders Identification Test Consumption (AUDIT-C) questionnaire are associated with mortality, but whether or how associations vary across race/ethnicity is unknown.

METHODS

Self-reported black (n = 13,068), Hispanic (n = 9,466), and white (n = 182,688) male Veterans Affairs (VA) outpatients completed the AUDIT-C via mailed survey. Logistic regression models evaluated whether race/ethnicity modified the association between AUDIT-C scores (0, 1 to 4, 5 to 8, and 9 to 12) and mortality after 24 months, adjusting for demographics, smoking, and comorbidity.

RESULTS

Adjusted mortality rates were 0.036, 0.033, and 0.054, for black, Hispanic, and white patients with AUDIT-C scores of 1 to 4, respectively. Race/ethnicity modified the association between AUDIT-C scores and mortality (p = 0.0022). Hispanic and white patients with scores of 0, 5 to 8, and 9 to 12 had significantly increased risk of death compared to those with scores of 1 to 4; Hispanic ORs: 1.93, 95% CI 1.50 to 2.49; 1.57, 1.07 to 2.30; 1.82, 1.04 to 3.17, respectively; white ORs: 1.34, 95% CI 1.29 to 1.40; 1.12, 1.03 to 1.21; 1.81, 1.59 to 2.07, respectively. Black patients with scores of 0 and 5 to 8 had increased risk relative to scores of 1 to 4 (ORs 1.28, 1.06 to 1.56 and 1.50, 1.13 to 1.99), but there was no significant increased risk for scores of 9 to 12 (ORs 1.27, 0.77 to 2.09). Post hoc exploratory analyses suggested an interaction between smoking and AUDIT-C scores might account for some of the observed differences across race/ethnicity.

CONCLUSIONS

Among male VA outpatients, associations between alcohol screening scores and mortality varied significantly depending on race/ethnicity. Findings could be integrated into systems with automated risk calculators to provide demographically tailored feedback regarding medical consequences of drinking.

U.S. mortality from liver cirrhosis and alcoholic liver disease in 1999-2004: regional and state variation in relation to per capita alcohol consumption

Apparent per-capita alcohol consumption in 2001 in four U.S. regions (West, Northeast, South, and Midwest), and in 50 states was examined in relation to mortality rates (1999-2004) from liver cirrhosis and for the subcategory alcoholic liver disease. Alcohol consumption and mortality rates were highest in the west. The alcoholic liver disease mortality rate by state was strongly correlated with alcohol consumption, but several outlier or mismatch states were identified. Per-capita alcohol consumption should be useful for US public health policy, as suggested for Europe and Canada, but outlier states require further study.

Disparities in patterns of alcohol use among reservation-based and geographically dispersed American Indian populations

BACKGROUND

High rates of alcohol use and alcohol-related morbidity and mortality among American Indians (AI) are major public health concerns. The purpose of this paper is to describe patterns of alcohol consumption among three distinct samples of American Indians (AIs) compared to a U.S reference population.

METHODS

Data were drawn from two epidemiologic studies: 1) a study of 2,927 AIs living on or near reservations from two culturally distinct tribes in the Southwest (SW-AI) and Northern Plains (NP-AI); and 2) the National Longitudinal Alcohol Epidemiologic Study (NLAES), which included data from a geographically dispersed sample of AIs (n = 780) as well as the US reference population (all-race excluding AIs, n = 30,063). Multivariate analyses were used to assess drinking patterns.

RESULTS

After controlling for demographic characteristics, the prevalence of drinking during the past year was similar among males in the NP-AI, NLAES-AI, and the US populations. SW-AI males and females were significantly less likely to drink during the past year (Odds Ratios of 0.74 and 0.41, respectively), while the odds of NP-AI females being current drinkers were twice that of US females. Among those who drank during the past year, the AIs consumed a larger quantity of alcohol per drinking day than the US reference population. However, the reservation-based AIs consumed alcohol less frequently (Odds Ratios between 0.18-0.40, p < 0.01) than the NLAES-AI and US populations.

CONCLUSIONS

Patterns of alcohol consumption varied substantially between the two reservation-based AI populations, the geographically dispersed sample of AIs, and the US reference population. Careful consideration of these variations may improve the effectiveness of alcohol prevention and treatment programs as they may reflect important underlying differences in the cultures of alcohol consumption across these populations.

Associations between early-adolescent substance use and subsequent young-adult substance use disorders and psychiatric disorders among a multiethnic male sample in South Florida

OBJECTIVES

We examined the associations among early-adolescent substance use, subsequent young-adult substance use disorders, and psychiatric disorders among a community sample of males.

METHODS

Early-adolescent data were collected in classroom surveys (1990-1993), and young-adult data were collected in face-to-face interviews (1998-2000).

RESULTS

We found strong associations between early-adolescent substance use and young-adult substance use disorders and psychiatric disorders. The magnitudes of these associations varied by racial/ethnic group and were strongest among African Americans and foreign-born Hispanics, who reported the lowest early-adolescent substance use.

CONCLUSIONS

Early-adolescent substance use is most strongly associated with a later pattern of dysfunction among the racial/ethnic groups that reported the lowest levels of early use. The implications of our findings in the context of primary and secondary prevention are discussed.

A comparison of traumatic brain injury in the Saskatchewan native North American and non-native North American populations

OBJECTIVE

To compare native North American and non-native North American patients admitted for inpatient rehabilitation following traumatic brain injury in order to identify pertinent differences between the two groups with regards to the initial injury, medical management and allocated resources.

DESIGN

A retrospective chart review was performed on all patients admitted to the unit between July 1994 and March 1997 with the diagnosis of traumatic brain injury.

RESULTS

Significant differences were found between the two groups in the areas of alcohol and drug involvement with the initial injury (p < 0.0001), geographical location of the injury (p < 0.0001), initial treatment received (p = 0.0102), discharge planning (p < 0.0001), and post-discharge follow-up (p = 0.0052).

CONCLUSIONS

The results indicate that native North Americans are more likely to suffer a head injury than non-native North Americans, that alcohol is more likely to be involved, and that native North American patients are less likely to be offered post-discharge resources. Further prospective study to explore these areas is required.

Health-related quality of life for rural American Indians in New Mexico

OBJECTIVES

To determine health-related quality of life for rural American Indians using an economical telephone surveillance system.

DESIGN

We interviewed 618 American Indians by telephone about health-related quality of life using an adaptation of the Behavioral Risk Factor Surveillance System questionnaire.

RESULTS

A smaller proportion of rural New Mexico American Indians (50.7%) reported their general health as 'excellent' or 'very good' compared to the overall New Mexico (58.2%) and US populations (57.9%). American Indians reported a mental health limitation more frequently than the New Mexico and the US populations. However, 13% fewer rural New Mexico American Indians reported a limitation in usual activities. Most limitations were due to musculoskeletal conditions or diabetes mellitus. Survey respondents were found to be representative of the rural American Indian population as reported by the 1990 US Census Bureau by tribal group affiliation and age, but were not representative by income, education, and gender.

CONCLUSIONS

Health-related quality of life for rural American Indians differs little from that of other New Mexicans and the general US population; however, when physical and mental health was rated as poor, fewer American Indians reported a limitation in usual activities. A telephone survey focusing on New Mexico American Indians is an efficient method by which to conduct surveillance of health-related quality of life.
