Abstract
This study compares a number of self-reported measures of drug use with the results of urine testing in a group of patients receiving methadone maintenance treatment. One hundred and twenty-nine subjects were interviewed and 4-5 months later, a second interview was obtained from 87 of these. At each interview subjects were asked about drug use on each of the preceding 7 days and also about the number of days of drug use in the previous month. It was found that most patients were continuing to use heroin, usually fairly infrequently. Direct comparisons of urine test results and self-reported drug use indicate substantial positive correlations. However, there was a tendency for self-report to underestimate drug use in this patient sample. It appears that urine testing is the single most useful measure of drug use. This supports the notion that it is a valid tool in evaluation research. However, the combination of self-report and urine tests provides more information about drug use than any single measure.

Abstract
The health and social conditions of women living in Vancouver's Downtown Eastside has recently been the focus of substantial international attention. Since few studies have examined rates and correlates of death among addicted women in Canada, we have characterized patterns of mortality among female injection drug users (IDUs) in Vancouver. The Vancouver Injection Drug Users Study (VIDUS) is a prospective open cohort study of IDUs. The analyses presented here, were restricted to women enrolled between May 1996 and May 2002 and who were aged 14 years or older. We estimated cumulative mortality rates using Kaplan-Meier methods and Cox regression was used to calculate univariate and adjusted relative hazards. Between May 1996 and May 2002, 520 female IDUs have been recruited from the Vancouver area among whom 68 died during the study period. Elevated rates of mortality were observed among those who reported, baseline sex-trade involvement, those with HIV-infection at baseline, and those who lived in unstable housing at baseline (all log-rank: p<0.05). In adjusted analyses, HIV infection (RH = 3.09 [95% CI: 1.86-5.11]; p<0.001), unstable housing (RH = 1.74 [95% CI: 1.10-2.86]; p=0.029) and sex-trade involvement (RH = 1.82 [95% CI: 0.95-3.45]; p=0.071) were associated with the time to death. When the number of observed deaths was compared to the number of expected deaths based on the general female population of British Columbia using indirect standardization, the rate of death among female IDUs was elevated by a factor of 47.3 (95% CI: 36.1-58.5). In Vancouver, female IDUs have rates of mortality almost 50 times that of the province's female population. Our findings are consistent with a growing number of reports from other settings internationally, and demonstrate the need for an appropriate evidence-based strategy to address the health and social needs of addicted women.

Abstract
OBJECTIVE To estimate the mortality rates from drug-related deaths and other causes among problem drug users and population attributable risk of death due to opiate use in eight study sites in Europe. METHODS Opiate users were recruited from drug treatment centres during the period 1990-1998 and deaths followed up through national or local mortality registries. Gender-specific overall mortality rate, proportion of deaths by cause (drug-related, HIV, other), standardized mortality ratios (SMRs), and the attributable risk fraction (ARF) were estimated. RESULTS Crude mortality rates varied from 1 per 100 person-years in the Dublin and London cohorts to 3.8 per 100 person-years in Barcelona. The highest drug-related mortality rate was 10 per 1,000 person-years in Barcelona; the rates were approximately 7 per 1,000 person-years in Denmark, London, Rome, and Vienna, and <3.5 per 1,000 person-years for the others cohorts. The mortality rate for AIDS was <2 per 1,000 person-years in all the cohorts except Lisbon, Rome, and Barcelona, for which it was approximately 6 per 1,000 person-years. The highest SMR among males was 21.1 in Barcelona, and among females the highest SMRs were 53.7 and 37.7 in Barcelona and Rome, respectively. In Denmark the ARF was 5%, whereas it was >10% in all other study sites and 24% in Barcelona. CONCLUSION Cohort mortality studies, especially in combination with estimates of prevalence, provide useful insights into the impact of opiate use on mortality across European countries and emphasize how preventing overall and drug-related deaths among opiate users can significantly improve the health of the population.

Abstract
PURPOSE This cross-sectional study investigated the predictors for and patterns of health care utilization among young adult injection drug users (IDUs). METHODS The subjects were 206 IDUs, ages 18-29, who were street-recruited from Harlem, New York. Participants were interviewed about their drug use, health conditions, and use of services such as health care, needle exchange programs (NEPs), and drug treatment in the preceding 6 months. Data were analyzed using logistic regression. RESULTS Health insurance was associated with use of health care both among NEP users [AOR (adjusted odds ratio) 10.66] and non-NEP users (AOR 2.45). Use of health care was independently associated with drug treatment (AOR 2.58), being gay/bisexual (AOR 3.86), and negatively associated with injecting cocaine (AOR 0.56). Half the participants (49%) had used health care in the previous 6 months; 48% were uninsured. Many participants who did not use health services reported a condition that would have warranted medical care. IMPLICATIONS Health insurance was strongly associated with use of health care, particularly among those who attend NEPs. Young adult IDUs may benefit from increased efforts to help them arrange and maintain health insurance coverage, potentially at NEPs. NEPs may be connecting young IDUs with health insurance to medical care through referrals.

Abstract
Injection drug use now accounts for the majority of new AIDS cases. Treatment for these patients is both more complex and more costly than for other AIDS patients as the factors associated with drug use are obstacles to treatment. Using data from a national survey of hospices, the findings from this study indicated that resources, hospice size, years in operation, and the Medicaid waiver were associated with hospice involvement with these patients. Staff training and supports are important factors in adequately dealing with the issues that these patients present.

Abstract
Within the framework of the Health Belief Model, this paper examines correlates of perception of AIDS susceptibility among 846 drug-using migrant farm workers and their sex partners. Significant but relatively small differences by ethnicity and gender were found. The data showed a consistent significant statistical relationship between frequency of drug use, high-risk sexual behavior, and perception of AIDS susceptibility. Perception of AIDS susceptibility was significantly related to a subsequent reduction in sexual risk behaviors. Consistent with the Health Belief Model, the data suggest that increasing perception of AIDS susceptibility may be an important motivator in reducing high-risk behaviors.

Abstract
Previous estimates from obituaries and pre-1994 sex surveys suggested that the median age of death for homosexuals is less than 50 yr. Four contemporary databases were used to test that estimate: (1) obituaries in the homosexual press from 1993 through 1997 reflected treatment success for those with AIDS but suggested a median age of death less than 50 years; (2) two large random sexuality surveys in 1994--one in the USA and the other in Britain--yielded results consistent with a median age of death for homosexuals of less than 50 years; (3) the median age of those ever married in Denmark, Sweden, and Norway was about 50 years, while that of the ever homosexually partnered was about 40 yr; further, the married were about 5 times more apt to be old and 4 times less apt to be widowed young; and (4) intravenous drug abusers and homosexuals taking HIV tests in Colorado had almost identical age distributions. The four lines of evidence were consistent with previous findings suggesting that homosexual activity may be associated with a lifespan shortened by 20 to 30 years.

Abstract
This paper describes changes in demographic characteristics and drug use patterns of persons who died while enrolled in a New York City methadone-maintenance program during the years preceding and subsequent to the AIDS epidemic. Persons dying from AIDS were more likely to be younger, Hispanic, and male than those dying from other causes. Drug use increased during the 12-year study period, and the spread of the HIV infection among drug users may be reflected in an increased use of injectable drugs.

Abstract
Women represent the fastest growing group of adults with AIDS, and poor African-American and Latina women are disproportionately affected. There are differences in the clinical presentation of HIV symptoms in women. Although disease progression seems to be similar for women and men, women with HIV infection seem to have a higher mortality rate than men. Gender, racial, and class differences in access to care may account for this. Phases of the natural history of HIV infection in women are reviewed and include prevention opportunities, acute infection, viral and immunologic parameters of pathogenesis, therapeutic plans, and terminal care.

Abstract
OBJECTIVES The purpose of the study was to analyze overall and cause-specific mortality among injection drug users in Rome. METHODS A cohort of 4200 injection drug users was enrolled in drug treatment centers from 1980 through 1988 and followed up until December 1992. RESULTS The age-adjusted mortality rate from all causes increased from 7.8/1000 person-years in 1985/86 to 27.7/1000 in 1991/92. The rise was mainly attributable to acquired immunodeficiency syndrome (AIDS), but mortality from overdose and other causes increased as well. The cumulative risk of death by the age of 40 was 29.3%. CONCLUSIONS The impact of AIDS deaths appears to be additional to a persistent increase of mortality for all other causes.

Abstract
The HIV/AIDS epidemic has had a profound impact on the organization and delivery of clinical services in drug abuse treatment programs. The need for emphasis on HIV prevention vs. treatment services has varied with the geographic distribution of HIV infection among drug injectors. On-site primary medical care services have been developed in some treatment programs, whereas other programs have had to formalize arrangements for referral or contractual care with outside medical providers. No single model of care is necessarily appropriate for all drug treatment programs, and, along with the potential benefit, each may pose structural challenges that need to be addressed. The advent of the AIDS epidemic may have served, in an inadvertently positive way, to draw attention to the increasingly illogical separation between drug abuse treatment and the larger medical care system. This review will examine the epidemiologic, clinical, organizational, and policy issues generated by the increased medical needs of drug users with HIV infection in treatment program settings.

Abstract
The purpose of this study is to model and predict the diffusion of the AIDS epidemic in Puerto Rico. Specifically we aim at identifying primary influences in the geographical distribution of the population affected with AIDS to produce a reasonable projection of the time and space paths that will be followed by the epidemic. The study is based on AIDS incidence data from 1982 through 1992. The epidemic is analyzed statistically through multivariate regression and the potential model to produce a probability surface in which risk behavior and intra-municipality mobility are significant risk factors. The growth forecast is produced using the logistic function fitted to the past growth using an iterative non-linear optimization method. A simulation technique is then employed to forecast the spatial development of the epidemic from 1993 through 1997. The results indicate a clear hierarchical tendency at the beginning of the epidemic, later a wave-like diffusion pattern is also observed. While the absolute number of new cases is expected to remain higher in the more urbanized areas, the relative growth of AIDS cases is likely to become much higher in the rural municipalities. The forecasting procedure employed here is applicable to populations with diverse epidemiological profiles.

Abstract
OBJECTIVE To determine HIV-1 incidence and HIV-1 associated mortality in a prospective cohort study. To determine whether the cohort is suitable for studies aiming to determine the impact of interventions on HIV-1 incidence. METHODS The study population was a cohort of 1772 urban factory workers (1478 men and 294 women) in northwest Tanzania. The study took place from October 1991 to September 1993. Outcome measures were HIV-1 seroconversion and death. RESULTS HIV-1 incidence was 1.2 (95% CI 0.7-2.0) per 100 person-years (pyr). Crude annual mortality was 4.9 per 100 pyr in those with and 0.3 in those without HIV-1 infection, giving an age and sex adjusted mortality ratio of 12.9 (95% CI 5.4-30.7). Of all deaths, 62% were attributable to HIV-1 infection. CONCLUSION HIV-1 infection was a major public health problem, being the major cause of death in this adult population. At an HIV-1 incidence of 1.2 per 100 pyr, a large cohort size would be required to evaluate the impact of interventions on HIV-1 incidence.

Abstract
Although the U.S. Surgeon General characterized homosexual sex as “normal” and “healthy,” homosexuals and IV drug abusers have suffered disproportionately from the AIDS epidemic. Longevity is often utilized as a measure of health. How long did homosexuals live before the AIDS epidemic and how long do they live today? We examined 6,737 obituaries/death notices from eighteen U.S. homosexual journals over the past thirteen years and compared them to obituaries from two conventional newspapers. The obituaries from the non-homosexual newspapers were similar to U.S. averages for longevity: the median age of death of married men was seventy-five, 80 percent died old (65 or older); for unmarried men it was fifty-seven, 32 percent died old; for married women it was seventy-nine, 85 percent died old; for unmarried women it was seventy-one, 60 percent died old. For the 6,574 homosexual deaths, the median age of death if AIDS was the cause was thirty-nine irrespective of whether or not the individual had a Long Time Sexual Partner [LTSP], 1 percent died old. For those 829 who died of non-AIDS causes the median age of death was forty-two (41 for those 315 with a LTSP and 43 for those 514 without) and <9 percent died old. Homosexuals more frequently met a violent end from accidental death, traffic death, suicide, and murder than men in general. The 163 lesbians registered a median age of death of forty-four (20% died old) and exhibited high rates of violent death and cancer as compared to women in general. Old homosexuals appear to have been proportionately less numerous than their non-homosexual counterparts in the scientific literature from 1858 to 1993. The pattern of early death evident in the homosexual obituaries is consistent with the pattern exhibited in the published surveys of homosexuals and intravenous drug abusers. Homosexuals may have experienced a short lifespan for the last 140 years; AIDS has apparently reduced it about 10 percent. Such an abbreviated lifespan puts the healthfulness of homosexuality in question.

Abstract
Over the past decade, two epidemics have had a severe impact on public health in this country. These health problems involve cocaine abuse and AIDS (or HIV disease). The processes of these two conditions are clearly not independent of each other and may be quite complex. Understanding of this relationship has been hampered by a myriad of social, biological and behavioral variables that are entangled with the basic cocaine-HIV association. This article presents a paradigm for discussion of the interaction between cocaine exposure and HIV disease based on three mechanisms: the relationship between cocaine exposure and increased opportunity for HIV exposure, the direct role that cocaine plays in altering susceptibility to HIV infection, and the influence that cocaine use has on the progression of HIV disease. The goal of this structured approach is to enhance conceptual understanding of the cocaine-HIV relationship while recognizing the complexity of the issue and the limitations of current research efforts. This model will serve as a framework for the discussion of implications for future research, clinical practice, and public policy.

Abstract
OBJECTIVE This study was undertaken to assess the completeness of vital statistics and case reports of acquired immunodeficiency syndrome (AIDS) in measuring human immunodeficiency virus (HIV)-related mortality in women 15 through 44 years of age. METHODS We used vital records to determine the number of deaths attributed to HIV infection and excess deaths due to causes that have increased in tandem with the HIV epidemic. RESULTS In 1988, among women 15 through 44 years of age, there were 1365 deaths with HIV infection listed as the underlying cause, 202 deaths with HIV infection listed as an associated cause, and 149 excess deaths due to conditions highly associated with HIV infection (subtotal = 1716). In addition, there were 780 excess deaths due to causes that may be related to HIV infection or illicit drug use (maximum estimate of HIV-related deaths = 2496). Of the deaths that occurred in 1988, 1532 were reported through AIDS surveillance (1668 deaths when adjusted for reporting delays). CONCLUSIONS Underlying-cause-of-death vital records and AIDS surveillance identified 55% to 80% and 67% to 97%, respectively, of HIV-related deaths in women 15 through 44 years of age in 1988. The wide ranges of these estimates reflect the potential role of both HIV infection and drug use in contributing to excess mortality.
