Increased risk of suicide in persons with AIDS

The rate of suicide has been reported to be higher in persons with chronic and life-threatening illnesses (eg, cancer, Huntington's disease, and renal failure). We studied the rate of suicide in 1985 in New York City residents diagnosed with the acquired immunodeficiency syndrome (AIDS). There were 668 suicides in New York City residents in 1985, yielding a rate of 9.29 per 100,000 person-years. In men aged 20 to 59 years without a known diagnosis of AIDS, the rate was 18.75 per 100,000 person-years. There were 3828 individuals who lived with the diagnosis of AIDS for some part, or all, of 1985. There were 12 suicides in men aged 20 to 59 years from this group who lived 1763.25 person-years with a diagnosis of AIDS. This yields a suicide rate of 680.56 per 100,000 person-years. Thus, the relative risk of suicide in men with AIDS aged 20 to 59 years was 36.30 times (95% confidence limits, 20.45 to 64.42) that of men aged 20 to 59 years without this diagnosis, and 66.15 times (95% confidence limits, 37.38 to 117.06) that of the general population. We conclude that AIDS represents a significant risk factor for suicide.     

Firearms suicides in Australia.

OBJECTIVE: To examine the rates of suicide by firearms in the five larger Australian States during 1968-1989, and to relate them to differences between those States. We hypothesised that (i) restrictive gun legislation will have reduced the firearms suicide rate in South Australia after 1980, and (ii) firearms suicides would be shown to be more common in States with larger rural:urban population ratios. DESIGN: Data supplied by the Australian Bureau of Statistics were analysed by sex, State and year of suicide. Differences between the firearms suicide rates of capital city and rural dwellers, and of different age-groups, were recorded. RESULTS: Firearms suicide rates in South Australia declined significantly after 1980, following proclamation of gun legislation, in contrast to the four other larger States where an increase in firearms suicides was recorded. The firearms suicide rate in Queensland has remained consistently higher than in the other four larger States during 1968-1989. The number of Australian firearms suicides per year fell by 25% from a peak of 572 in 1987 to 451 in 1989. CONCLUSIONS: Further reductions in the Australian firearms suicide rate might be achieved by tightening gun laws and by a media campaign aimed at reducing easy access by males to guns in rural households.     

Trends of HIV seroconversion among young adults in the US Army, 1985 to 1989. US Army Retrovirus Research Group

Because soldiers in the US Army are recurrently tested for the presence of antibody to the human immunodeficiency virus (HIV), HIV seroconversion rates can be directly measured. From November 1985 through October 1989, 429 HIV seroconversions were detected among 718,780 soldiers who contributed 1,088,447 person-years of follow-up time (HIV seroconversion rate, 0.39 per 1000 person-years). Period-specific seroconversion rates declined significantly from 0.49 per 1000 person-years (November 1985 through October 1987) to 0.33 per 1000 person-years (November 1987 through October 1988) to 0.29 per 1000 person-years (November 1988 through October 1989). The HIV seroconversion risk among active-duty soldiers was significantly associated with race/ethnic group, age, gender, and marital status. Based on these trends, we estimate that approximately 220 soldiers (95% confidence interval, 160 to 297 soldiers) were infected with HIV during 1989 and 1990, with potentially fewer in future years.     

Residents' experiences in, and attitudes toward, the care of persons with AIDS in Canada, France, and the United States.

OBJECTIVE--To evaluate resident physicians' experiences in, and attitudes toward, the care of persons with the acquired immunodeficiency syndrome (AIDS) in Canada, France, and the United States. DESIGN--Cross-sectional survey, using a self-administered, mailed questionnaire to residents in 10 American states, three French regions, and all 10 Canadian provinces, with follow-up surveys of nonresponders in France and the United States. SUBJECTS--Systematic samples of residents in the last year of internal medicine or family medicine residencies prior to subspecialization or entry into medical practice. RESULTS--While the majority of residents had provided inpatient and outpatient care to persons with AIDS, most believed that their training in ambulatory care of persons with AIDS had been deficient. The rate of blood-contaminated needle-sticks from human immunodeficiency virus-infected patients ranged from 4% for internal medicine residents in Canada to 14% in the United States (P less than .05). The majority recognized an ethical obligation to treat AIDS, but 4% in France, 14% in Canada, and 23% in the United States indicated that they would not care for persons with AIDS if they had a choice (P less than .001). A substantial minority of US physicians reported that a patient of theirs had been refused care by a medical specialist (19%) or a surgeon (39%), but less than 10% of French physicians reported such refusals (P less than .001). CONCLUSION--Concerns about caring for AIDS patients were common and many physicians reported that patients were refused care. While most residents acknowledged an obligation to treat human immunodeficiency virus infection, many did not, and viewpoints varied considerably across the countries studied. The lower level of reluctance to treat AIDS patients in France and Canada makes it clear that the higher rate in the United States is far from optimal and needs to be addressed.     

Suicide risk among recently released prisoners in New South Wales, Australia

OBJECTIVE: To determine the risk of suicide and drug overdose death among recently released prisoners. DESIGN, SETTING AND PARTICIPANTS: Retrospective cohort study of 85 203 adult offenders who had spent some time in full-time custody in prisons in New South Wales between 1 January 1988 and 31 December 2002. MAIN OUTCOME MEASURES: Association between time after release and risk of suicide and overdose death. RESULTS: Of 844 suicides (795 men, 49 women), 724 (86%) occurred after release. Men had a higher rate of suicide than women both in prison (129 v 56 per 100,000 person-years) and after release (135 v 82 per 100,000 person-years). The suicide rate in men in the 2 weeks after release was 3.87 (95% CI, 2.26-6.65) times higher than the rate after 6 months. Male prisoners admitted to the prison psychiatric hospital had a threefold higher risk than non-admitted men both in prison and after release. No suicides among women were observed in the 2 weeks after release. No increased risk of suicide was observed among Aboriginal Australians in the first 2 weeks after release. Of 1674 deaths due to overdose, 1627 (97%) occurred after release. Drug-related mortality in men was 9.30 (95% CI, 7.80-11.10) times higher, and in women was 6.42 (95% CI, 3.88-10.62) times higher, in the 2 weeks after release than after 6 months. CONCLUSIONS: Prisoners are at a heightened risk of suicide and overdose death in the immediate post-release period. After 6 months post-release, the suicide rate approaches the rate observed in custody.     

Population-based epidemiology of human immunodeficiency virus infection in Western Australia. Western Australian AIDS Advisory Committee

A total of 328 cases of infection with human immunodeficiency virus (HIV) in Western Australia in 1983-1987 was studied with respect to demographic factors, the risk profile, the clinical progression of disease, the utilization of inpatient services and trends in incidence over time. The crude incidence rates were 8.8 cases/100,000 person-years in men and 0.4 cases/100,000 person-years in women. Age-specific rates peaked at 25 to 29 years of age in men. The risk of HIV infection was associated with metropolitan residence, low socioeconomic level, and two specific occupational groups. Homosexual and bisexual men constituted 86% of all cases; the incidence rate of HIV infection in such men was approximately 1000-times higher than was the incidence rate by apparent sexual transmission in heterosexual persons. However, the proportion of cases that occurred in women or that apparently was caused by heterosexual sexual transmission increased from zero in 1983-1984 to 7.5% and 5.4%, respectively, in 1987. After two years of follow-up, 71% of preclinical (category-C) patients had developed signs, symptoms or evidence of immune dysfunction, and 12% of those patients with lymphadenopathy or with other early clinical features of disease (category-B) had progressed to the acquired immunodeficiency syndrome (AIDS). At 21 months of follow-up, the survival rate with AIDS was 9%. Patients with AIDS utilized an average of 68.9 short-stay hospital bed-days per person-year, while category-B patients used 11.5 hospital bed-days per person-year. Notifications of HIV infection increased each year from 1983 to 1986, but fell by 22% in 1987. The latter may have been as a result of chance, a screening artefact or a real reduction in the incidence rate.     

Human immunodeficiency virus infection in Northern Ireland 1980-1989.

To 31st December 1989, 71 persons are known to have attended medical practitioners in Northern Ireland with a diagnosis of Human Immunodeficiency Virus (HIV) infection. Twenty-one of these persons have had the diagnosis of Acquired Immune Deficiency Syndrome (AIDS) and 11 have died. The distribution of reports in the "at risk" categories of homosexual/bisexual males, injecting drug users, heterosexual males and females was significantly different (p less than 0.001) from those reported in the United Kingdom as a whole. Of tests for HIV infection carried out in patients attending the genitourinary medicine department of the Royal Victoria Hospital between 1987-1989, 0.16% have been positive. The prognostic value of the T4 lymphocyte count at presentation for the subsequent development of AIDS was significant (p = 0.0011). The commonest AIDS indicator disease diagnosed was Pneumocystis carinii pneumonia which was seen in seven of the 21 patients (33%).     

Diarrheal deaths in the United States, 1979 through 1987. A special problem for the elderly

OBJECTIVE.--Diarrhea is an important cause of death among young children in both developing and developed countries, but little is known about diarrheal death among adults. In this study, we examined trends in diarrheal deaths among all age groups in the United States. DESIGN/SETTING/PARTICIPANTS.--We reviewed national mortality data complied by the National Center for Health Statistics, Hyattsville, Md, which consists of information from all death certificates filed in the United States for the period 1979 through 1987. A death for which diarrhea was listed as an immediate or underlying cause was considered a "diarrheal death" and included in the analysis. RESULTS.--We found that 28,538 persons died of diarrhea cited as either an immediate or the underlying cause of death during the 9-year period. A majority of diarrheal deaths occurred among the elderly (older than 74 years of age, 51%), followed by adults 55 to 74 years of age (27%), and young children (younger than 5 years of age, 11%). For the elderly, adjusted risk factors for dying of diarrhea included being white, female, and residing in a long-term care facility. Only the elderly and young children had clear, distinct winter peaks of diarrheal deaths, suggesting that the diarrhea may, in part, be infectious in origin. CONCLUSION.--For the elderly, more directed studies of those at risk, such as nursing home residents, are needed to determine if oral rehydration therapy, vaccines, or other preventive measures might benefit this population.     

HIV-1 infection among intravenous drug users in Manhattan, New York City, from 1977 through 1987

Intravenous drug users are the second largest group to develop the acquired immunodeficiency syndrome, and they are the primary source for heterosexual and perinatal transmission in the United States and Europe. Understanding long-term trends in the spread of human immunodeficiency virus among intravenous drug users is critical to controlling the acquired immunodeficiency syndrome epidemic. Acquired immunodeficiency syndrome surveillance data and seroprevalence studies of drug treatment program entrants are used to trace seroprevalence trends among intravenous drug users in the borough of Manhattan. The virus entered this drug-using group during the mid-1970s and spread rapidly in 1979 through 1983. From 1984 through 1987, the seroprevalence rate stabilized between 55% and 60%--well below hepatitis B seroprevalence rates. This relatively constant rate is attributed to new infections, new seronegative persons beginning drug injection, seropositive persons leaving drug injection, and increasing conscious risk reduction.     

Impact of the human immunodeficiency virus epidemic on mortality in women of reproductive age, United States

To assess the effect of the human immunodeficiency virus (HIV) on mortality in US women 15 to 44 years of age and to identify associated causes of death, we examined final (1980 through 1987) and provisional (1988) national mortality statistics. Between 1985 and 1988, the death rate for HIV/acquired immunodeficiency syndrome (AIDS) quadrupled (0.6 per 100,000 to 2.5 per 100,000), and by 1987, HIV/AIDS had become one of the 10 leading causes of death. In 1988, the death rate for black women (10.3 per 100,000) was nine times the rate for white women (1.2 per 100,000). The majority of deaths in both black and white women occurred in women 25 to 34 years of age, for whom HIV-related deaths accounted for 11% and 3% of all deaths in 1988, respectively. Among 1157 death certificates that included any mention of HIV/AIDS in 1987, other leading diagnoses included drug abuse (27%), Pneumocystis carinii pneumonia (20%), other pneumonias (14%), septicemia (10%), other infections not in the AIDS surveillance definition (7%), nephritis (6%), liver diseases (4%), and anemias (4%). If current mortality trends continue, HIV/AIDS can be expected to become one of the five leading causes of death by 1991 in women of reproductive age. Because women infected with HIV are the major source of infection for infants, these trends in AIDS mortality in women forecast the impact of HIV on mortality in children as well.     

Health care workers with AIDS. National surveillance update.

OBJECTIVES--To characterize health care workers with the acquired immunodeficiency syndrome (AIDS) in the United States and to evaluate the role of occupational transmission of the human immunodeficiency virus (HIV). DATA SOURCE--National AIDS surveillance data. METHODS--Health care workers with AIDS are reported to the Centers for Disease Control by state and local health departments. Health care workers who do not report a nonoccupational risk for HIV infection are termed undetermined risk cases and are investigated by health departments using a standard protocol. RESULTS--Through June 30, 1990, there were 5425 cases of AIDS in health care workers reported in the United States. Three of these workers developed AIDS following well-documented occupational exposure to HIV-infected blood. Of the 539 health care workers initially reported without a nonoccupational risk, follow-up investigations were completed for 303. Nonoccupational risk factors were established for 237 (78.2%) of the 303 investigated health care workers; 66 workers (21.8%) remained in the undetermined category. Follow-up information was incomplete for 236 health care workers who also remained in the undetermined category, resulting in 5120 health care workers (94.4%) with AIDS with nonoccupational risks for HIV infection. Overall, health care workers were more likely than non-health care workers with AIDS to have an undetermined risk for HIV infection (5.6% vs 2.8%; P less than .001). While many of the 66 investigated health care workers had jobs involving contact with patients and/or potential contact with blood, none reported percutaneous, mucous membrane, or cutaneous exposures to blood or body fluids known to be infected with HIV. CONCLUSION--Surveillance data suggest that most health care workers with AIDS acquired their HIV infection through a nonoccupational route.     

Epidemiology of primary and secondary syphilis in the United States, 1981 through 1989

Between 1981 and 1989, the incidence of primary and secondary syphilis in the United States increased 34%, from 13.7 to 18.4 cases per 100,000 persons, the highest since 1949. The populations affected most by syphilis also changed substantially. From a peak of 10.0 cases per 100,000 persons in 1982, the incidence among white men had decreased 69% by 1989 (3.2 cases per 100,000 persons). From 1982 to 1985, the incidence also decreased among black men (30%, 101.9 to 71.5 cases per 100,000) and black women (22%, 45.8 to 35.8 cases per 100,000). However, in 1986 this trend reversed, and the incidence among blacks more than doubled from 1985 to 1989 (52.6 to 121.8 cases per 100,000 persons). Racial differences in syphilis incidence increased (black-to-white incidence rate ratio in 1981 was 14.5 and in 1989 was 47.8), as did regional differences. Trends in syphilis incidence indicate changes in sexual behavior that may determine future sexual transmission of human immunodeficiency virus. Targeting resources at populations most affected by this recent epidemic is an urgent public health priority.     

Risk of cancer in children with AIDS. AIDS-Cancer Match Registry Study Group

CONTEXT: Population-based data on cancers associated with acquired immunodeficiency syndrome (AIDS) in children are lacking. OBJECTIVE: To determine risk of pediatric AIDS-associated cancers. DESIGN, SETTING, AND PARTICIPANTS: Using records from 11 locations in the United States for varying periods between 1978 and 1996, we linked data for children aged 14 years and younger at AIDS diagnosis to local cancer registry data. MAIN OUTCOME MEASURES: Cancer frequency and, in the 2-year post-AIDS onset period, cancer incidence and relative risk (RR; measured as standardized incidence ratio), by cancer type. RESULTS: Among 4954 children with AIDS, 124 (2.5%) were identified as having cancer before, at, or after AIDS onset, including 100 cases of non-Hodgkin lymphoma (NHL), 8 of Kaposi sarcoma (KS), 4 of leiomyosarcoma, and 2 of Hodgkin disease; there were 10 other or unspecified cancers. Expected numbers for all cancers identified in the study sample, based on population rates (using area-specific registry data), were less than 1. In the first 2 years after AIDS diagnosis (5485 person-years), NHL incidence was 510 per 100,000 person-years (RR, 651; 95% confidence interval [CI], 432-941). Median time for developing NHL after AIDS diagnosis was 14 months (range, 3-107 months). The most common type of NHL was Burkitt lymphoma. However, the risk of primary brain lymphoma (91 per 100,000 person-years) was especially high (RR, 7143; 95% CI, 2321-16,692), and 4 cases were diagnosed more than 2 years (range, 37-98 months) after AIDS onset. Leiomyosarcomas also tended to occur several years after AIDS onset, with 3 of the 4 cases occurring 33 to 76 months after AIDS diagnosis, whereas KS was reported only at or within 2 years of AIDS diagnosis. Hodgkin disease risk was also significantly increased (RR, 62; 95% CI, 2-342). CONCLUSIONS: The spectrum of AIDS-associated pediatric cancers resembled that seen in adults, with the addition of leiomyosarcoma. Both primary brain lymphomas and leiomyosarcomas tended to occur in children surviving several years after AIDS onset. Because the expected numbers of these cancers in this population were less than 1 and because of the small numbers of some types of observed cancers, the RR estimates are imprecise and caution is warranted in their interpretation.

Spectrum of disease in persons with human immunodeficiency virus infection in the United States.

OBJECTIVE--To describe the spectrum of disease in persons with human immunodeficiency virus (HIV) infection. DESIGN--Retrospective survey of medical records. SETTING--More than 50 clinics, hospitals, and private medical practices in nine US cities. PATIENTS--A total of 626 women and 7008 men 13 years of age or older with HIV infection who received medical care from January 1990 through March 1991 were consecutively enrolled. MAIN OUTCOME MEASURES--Any history of diseases in the 1987 case definition for the acquired immunodeficiency syndrome (AIDS), and during the 12-month period preceding enrollment (baseline period), the occurrence of other major diseases, hospitalizations, and results of CD4+ lymphocyte counts. RESULTS--Thirty-two percent of persons met the 1987 case definition for AIDS. The occurrence of an AIDS-indicator disease during the baseline period ranged from 3% (33/1011) to 46% (1254/2748) among persons with CD4+ lymphocyte counts of 0.50 x 10(9)/L or greater and fewer than 0.20 x 10(9)/L (greater than or equal to 500 and less than 200 CD4+ lymphocytes per microliter), respectively, and, at comparable CD4+ lymphocyte levels, was similar among women compared with men, and among persons who reported intravenous drug use compared with men who reported male-to-male sex. The frequency of one or more other major infectious diseases (eg, other pneumonias, bacterial sepsis, pulmonary tuberculosis) ranged from 6% to 16% among persons with CD4+ lymphocyte counts of 0.50 x 10(9)/L or greater and fewer than 0.20 x 10(9)/L, respectively; these illnesses were also associated with a history of intravenous drug use. Among persons who did not meet the 1987 AIDS case definition, 30% of those with an available CD4+ lymphocyte count had fewer CD4+ cells than 0.20 x 10(9)/L, 8% had one or more major infectious diseases, and 14% had one or more hospital admissions. CONCLUSIONS--For every person with AIDS at these sites, two additional persons with HIV infection were receiving medical care, many of whom had severe immunosuppression and a broad spectrum of serious HIV-related disease.     

AIDS: the HIV epidemic. A time of transition

The surveillance of clinical cases of acquired immune deficiency syndrome (AIDS) in the United States began in June 1981 when the first case was reported. Since then, state and federal public health officials have continuously monitored progression of the epidemic by the number of persons reported with diagnosed clinical AIDS. The human immunodeficiency virus (HIV) that causes AIDS was identified in 1983 and an antibody test was licensed by the Food and Drug Administration in 1985. Recent studies have shown that the time from HIV infection to development of clinical AIDS is an average of seven or more years. Consequently, the reported cases of clinical AIDS reflect the severity of the epidemic an average of seven years ago or more, not now, and certainly not in the future. The AIDS epidemic is in reality an HIV epidemic. The number of persons with HIV infections is a better measure of the present status and future course of the disease. This paper discusses the development of HIV prevalence and incidence studies and illustrates the use of these data to predict the future number of persons with clinical AIDS and the economic impact of the epidemic.     

Maternal mortality in women aged 35 years or older: United States

To examine maternal mortality among women aged 35 years or older, we used death certificates from the United States for 1974 through 1978. There were 425 maternal deaths, corresponding to a mortality rate of 58.3 deaths per 100,000 live births. This rate was higher than the rate for women 20 through 34 years of age (race-adjusted relative risk [RR] = 4.0; 95% confidence interval [CI], 3.6 to 4.4). The leading causes of death were obstetric hemorrhage and embolism. Black women had higher mortality rates than white women for deaths without abortive outcomes (RR = 3.3; CI, 2.7 to 4.1) and with abortive outcomes (RR = 9.4; 95% CI, 5.8 to 15.3), and the latter difference was largely due to a higher rate of deaths associated with ectopic pregnancy among black women. From 1974 through 1978, compared with 1982, maternal mortality rates for women aged 35 years or older reported by the National Center for Health Statistics declined approximately 50%. Among white women, changes in age and parity accounted for less than half of this decrease, suggesting that improvements have occurred in age- and parity-specific mortality for women aged 35 years or older.     

International correlations between gun ownership and rates of homicide and suicide.

OBJECTIVE: To examine international correlations between reported rates of household gun ownership and rates of homicide and suicide with a gun. DESIGN: Survey. POPULATION: People who responded to a telephone survey conducted by the 1989 International Crime Survey in 11 European countries, Australia, Canada and the United States. RESULTS: Positive correlations were obtained between the rates of household gun ownership and the national rates of homicide and suicide as well as the proportions of homicides and suicides committed with a gun. There was no negative correlation between the rates of ownership and the rates of homicide and suicide committed by other means; this indicated that the other means were not used to "compensate" for the absence of guns in countries with a lower rate of gun ownership. CONCLUSION: Larger studies are needed to examine more closely possible confounding factors such as the national tendency toward violent solutions, and more information on the type and availability of guns will be helpful in future studies. Nevertheless, the correlations detected in this study suggest that the presence of a gun in the home increases the likelihood of homicide or suicide.     

Sociodemographic characteristics of cigarette smoking initiation in the United States. Implications for smoking prevention policy

Cigarette smoking initiation greatly influences smoking prevalence in the United States. To understand better the initiation of cigarette smoking, we estimated the age-specific incidence of cigarette smoking initiation in relation to race/ethnicity, sex, and educational attainment, using the reported age at smoking onset for 18- to 35-year-old respondents in the 1987 National Health Interview Survey (N = 14764) and the Hispanic Health and Nutrition Examination Survey (N = 3123) conducted during 1982 to 1984. Among white, black, and Hispanic respondents the incidence of smoking initiation increased rapidly after 11 years of age, reaching a peak in groups 17 to 19 years of age, rapidly declining in groups through age 25 years, and gradually declining thereafter. Age-specific smoking initiation rates were generally lower among black than white respondents, similar between white and Hispanic respondents, and appreciably higher among black and Hispanic men than women. Compared with persons who graduated from high school, persons with less than high school education were consistently more likely to start smoking cigarettes during childhood and adolescence. These data indicate that age and educational attainment are the factors most consistently associated with cigarette smoking initiation among all race/ethnic groups in the United States. These data also emphasize the need for smoking-prevention education beginning at an early age, particularly among persons of low socioeconomic status.
