Suicide Among Adult Cancer Survivors, 2000-2019

<h3>Purpose/Objective(s)</h3> Cancer patients are at elevated risk of suicide due to additional disease-specific factors relating to cancer and its treatments. Given that cancer survivorship in the United States continues to improve, evaluating the risk and identifying factors associated with suicide among cancer survivors is warranted. <h3>Materials/Methods</h3> This population-based study examined the National Center for Health Statistics Multiple-Cause Mortality data for adult cancer survivors aged ≥ 20 with suicide and self-inflicted injury as the underlying cause and malignant neoplasm as a contributing cause of death. Associations with death by suicide were assessed with multivariable logistic regression for demographic and comorbid factors, and univariate logistic regression for anatomic site of cancer stratified by sex. Trends in suicide rates of non-cancer and cancer survivors were assessed with Pearson's correlation coefficient. <h3>Results</h3> Among 12,180,902 adult cancer survivors, 6,254 (0.051%) deaths were by suicide. Male sex, White race, being not married, and having a high school education or higher, were associated with increased odds of suicide. Cancer survivors with a documented history of substance use disorder (OR [95% CI], 0.35 [0.31-0.39], <i>P</i> < .001) or chronic medical condition (0.36 [0.34-0.39], <i>P</i> < .001) had decreased odds, while history of depressive disorder had significantly increased odds of suicide (97.44 [90.61-104.78], <i>P</i> < .001), compared to those without the respective comorbidity. Survivors of head and neck, female breast, or genitourinary cancers had increased likelihood of death by suicide compared to those of thoracic sites (Table). Over the study period, the suicide rate of those without a history of cancer increased (r = 0.95, <i>P</i> < .0005) while the overall suicide rate of cancer survivors decreased (r = -0.60, <i>P</i> = 0.005). Specifically, suicide rates decreased for thoracic, gastrointestinal, genitourinary, and head and neck cancers, with the largest decline in multiple, metastatic, not otherwise specified sites (r = -0.67, <i>P</i> = 0.001). <h3>Conclusion</h3> Among adult cancer survivors, suicide risk varies with sociodemographic status, comorbid conditions, and anatomic cancer site. Although the suicide rate of cancer survivors has declined overall, further research is needed to develop interventions in high-risk cancer patients, particularly those with a history of depression, to mitigate suicide risk and improve survivorship care.

Nonalcoholic Fatty Liver Disease and Alcoholic Liver Disease are Major Drivers of Liver Mortality in the United States.

In the United States, chronic viral hepatitis B and C (CHB and CHC), nonalcoholic fatty liver disease (NAFLD), and alcohol‐related liver disease (ALD) are the main causes of liver deaths attributable to hepatocellular carcinoma (HCC) and cirrhosis. Our aim was to assess the changes in the rates of mortality and years of potential life lost (YLL) for HCC and cirrhosis due to different liver diseases. We used multiple‐cause mortality data (2007‐2017) from the National Center for Health Statistics. Annual percentage change (APC) in age‐standardized death rate per 100,000 (ASDR) and age‐standardized years of life lost per 100,000 (ASYLLR) were calculated. In the United States in 2017, there were 2,797,265 deaths with 73,424 liver deaths, contributing to 1,467,742 of YLL. Of the liver deaths, HCC was noted in 12,169 (16.6%) and cirrhosis in 60,111 (82.0%). CHC was responsible for 50.4% of HCC deaths; NAFLD, 35.4%; HBV, 6.0%; ALD, 5.4%; and others, 2.8%. NAFLD was responsible for 48.9% of cirrhosis deaths; ALD, 34.7%; CHC, 12.3%; CHB, 0.9%; and others, 3.2%. Between 2007 and 2017, the increase in ASDR for HCC due to ALD and NAFLD accelerated after 2014 (APC, 11.38% and 6.55%, respectively) whereas CHC stabilized (APC, 0.63%; P = 0.272) after 2011. The increase in ASYLLR of HCC escalated after 2014 for ALD and NAFLD (APC, 12.12% and 6.15%, respectively) and leveled out for CHC after 2012 (APC, −1.05%; P = 0.056). Furthermore, the highest annual increase in ASDR and ASYLLR for cirrhosis was due to ALD (APC, 3.24% and 3.34%, respectively) followed by NAFLD (APC, 1.23% and 0.49%, respectively). Conclusion: Over the past decade, ASDR and ASYLLR due to ALD and NAFLD have been increasing in the United States. The rising burden of HCC and cirrhosis are primarily driven by NAFLD and ALD.

Prevalence and hospital discharge status of human immunodeficiency virus-associated pulmonary arterial hypertension in the United States.

Pulmonary arterial hypertension (PAH) is a noninfectious complication of human immunodeficiency virus (HIV) infection that has gained in importance since the advent of antiretroviral therapy. HIV-associated PAH (HIV-PAH) has a higher prevalence than idiopathic PAH (IPAH), although the vascular pathology seen in HIV-PAH is virtually identical to that seen in IPAH. Initiating therapy for PAH at an early stage is associated with a better prognosis; however, because of the nonspecific symptoms associated with PAH, the diagnosis is often delayed. In addition, because of the low prevalence of HIV-PAH, routine screening for this condition has never been recommended. We hypothesize that the failure to create screening guidelines for HIV-PAH has resulted in underdiagnosis of the condition. This, in turn, results in individuals with HIV-PAH remaining undetected, allowing the disease to progress to more advanced stages or even remain unrecognized until death. If this hypothesis is correct, it may provide a strong argument for HIV-PAH screening guidelines, because HIV-PAH portends a poor prognosis and creates a significant economic burden if left untreated. To address this issue, we conducted a retrospective review of the National Hospital Discharge Survey data and the multiple-cause mortality data to determine the prevalence of HIV-PAH at hospital discharge and death. Using these large data sets, we observed that the prevalence of HIV-PAH among HIV-infected individuals at hospital discharge and death was significantly lower than the reported prevalence in the literature. In addition, we found that PAH was designated as the most common cause of mortality in patients with HIV-PAH.

Trends in Unintentional Fall-Related Traumatic Brain Injury Death Rates in Older Adults in the United States, 1980-2010: A Joinpoint Analysis.

Unintentional fall-related traumatic brain injury (TBI) death rate is high in older adults in the United States, but little is known regarding trends of these death rates. We sought to examine unintentional fall-related TBI death rates by age and sex in older adults from 1980 through 2010 in the United States. We used multiple-cause mortality data from 1980 through 2010 (31 years of data) to identify fall-related TBI deaths. Using a joinpoint regression program, we determined the joinpoints (years at which trends change significantly) and annual percentage changes (APCs) in mortality trends. The fall-related TBI death rates (deaths per 100,000 population) in older adults ages 65-74, 75-84, and 85 years and above were 2.7, 9.2, and 21.5 for females and 8.5, 18.2, and 40.8 for males, respectively, in 1980. The rate was about the same in 1992, yet increased markedly to 5.9, 23.4, and 68.9 for females and 11.6, 41.2, and 112.4 for males, respectively, in 2010. For males all 65 years years of age and above, we found the first joinpoint in 1992, when the APC for 1980 through 1992, -0.8%, changed to 6.2% for 1992-2005. The second joinpoint occurred in 2005, when the APC decreased to 3.7% for 2005-2010. For all females 65 years of age and above, the first joinpoint was in 1993 when the APC for 1980 through 1993, -0.2%, changed to 7.6% from 1993 to 2005. The second joinpoint occurred in 2005 when the APC decreased to 3.8% for 2005-2010. This descriptive epidemiological study suggests increasing fall-related TBI death rates from 1992 to 2005 and then a slowdown of increasing trends between 2005 and 2010. Continued monitoring of fall-related TBI death rate trends is needed to determine the burden of this public health problem among older adults in the United States.

Comparison of Rates of Death Having any Death-Certificate Mention of Heart, Kidney, or Liver Disease Among Persons Diagnosed with HIV Infection with those in the General US Population, 2009-2011.

Objective : Compare age-adjusted rates of death due to liver, kidney, and heart diseases during 2009-2011 among US residents diagnosed with HIV infection with those in the general population.Methods : Numerators were numbers of records of multiple-cause mortality data from the national vital statistics system with an ICD-10 code for the disease of interest (any mention, not necessarily the underlying cause), divided into those 1) with and 2) without an additional code for HIV infection. Denominators were 1) estimates of persons living with diagnosed HIV infection from national HIV surveillance system data and 2) general population estimates from the US Census Bureau. We compared age-adjusted rates overall (unstratified by sex, race/ethnicity, or region of residence) and stratified by demographic group.Results : Overall, compared with the general population, persons diagnosed with HIV infection had higher age-adjusted rates of death reported with hepatitis B (rate ratio [RR]=42.6; 95% CI: 34.7-50.7), hepatitis C (RR=19.4; 95% CI: 18.1-20.8), liver disease excluding hepatitis B or C (RR=2.1; 95% CI: 1.8-2.3), kidney disease (RR=2.4; 95% CI: 2.2-2.6), and cardiomyopathy (RR=1.9; 95% CI: 1.6-2.3), but lower rates of death reported with ischemic heart disease (RR=0.6; 95% CI: 0.6-0.7) and heart failure (RR=0.8; 95% CI: 0.6-0.9). However, the differences in rates of death reported with the heart diseases were insignificant in some demographic groups.Conclusion : Persons with HIV infection have a higher risk of death with liver and kidney diseases reported as causes than the general population.

Reporting of Aspiration Pneumonia or Choking as a Cause of Death in Patients Who Died With Stroke

It is not known how many stroke patients die from fatal pulmonary complications such as aspiration pneumonia (AP) and choking each year in the United States. This study aimed to determine the frequency of reporting of AP or choking as a cause of death on death certificates with mention of stroke in the United States as a proxy measure of the incidence of dying from AP or choking among patients with stroke. We used multiple-cause mortality data for the years 2001 to 2010 to identify death certificates with mention of stroke (International Classification of Diseases, Tenth Revision code I60-I69), AP (International Classification of Diseases, Tenth Revision code J69), and choking (International Classification of Diseases, Tenth Revision code W78-W80) for analysis. Of 2 424 379 death certificates with mention of stroke in the United States between 2001 and 2010, 5.1% (n=124 503) reported AP as a cause of death, and 1.5% (n=36 997) reported choking as a cause of death. However, if we confined the analysis to autopsy-confirmed cases, the frequency decreased to 1.3% (555/42 732) and 1.3% (541/42 732), respectively. The adjusted odds ratios of reporting AP or choking as a cause of death were higher among men, increased with age, and were higher among decedents who died in a nursing home/long-term care. The estimated incidence of dying from AP and choking among patients who died with stroke was 5% (~12 000 deaths per year) and 1% (~3700 deaths per year) according to information reported on death certificates. Efforts are needed to reduce the number of deaths from these 2 preventable complications.

The Increasing Burden of Mortality From Viral Hepatitis in the United States Between 1999 and 2007

The increasing health burden and mortality from hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States are underappreciated. To examine mortality from HBV; HCV; and, for comparison, HIV. Analysis of U.S. multiple-cause mortality data from 1999 to 2007 from the National Center for Health Statistics. All U.S. states and the District of Columbia. Approximately 22 million decedents. Age-adjusted mortality rates from HBV, HCV, and HIV. Logistic regression analyses of 2007 data generated 4 independent models per outcome (HCV- or HBV-related deaths) that each included 1 of 4 comorbid conditions and all sociodemographic characteristics. Between 1999 and 2007, recorded deaths from HCV [corrected] increased significantly to 15,106, whereas deaths from HIV declined to 12,734 by 2007. Factors associated with HCV-related deaths included chronic liver disease, HBV co-infection, alcohol-related conditions, minority status, and HIV co-infection. Factors that increased odds of HBV-related death included chronic liver disease, HCV co-infection, Asian or Pacific Islander descent, HIV co-infection, and alcohol-related conditions. Most deaths from HBV and HCV occurred in middle-aged persons. A person other than the primary physician of the decedent frequently completed the death certificate, and HCV and HBV often were not detected and thus not reported as causes of death. By 2007, HCV had superseded HIV as a cause of death in the United States, and deaths from HCV and HBV disproportionately occurred in middle-aged persons. To achieve decreases in mortality similar to those seen with HIV requires new policy initiatives to detect patients with chronic hepatitis and link them to care and treatment.

How Can the National Burden of Parkinson’s Disease Comorbidity and Mortality Be Estimated for the Japanese Population?

BackgroundGood medical care results in long survival for patients with Parkinson’s disease (PD). However, little is known about the burden of PD comorbidity and mortality in Japan. This is the first study to examine comorbid diseases of PD decedents and extrapolate PD death rates from multiple-cause coding mortality data for the total population of Japan.MethodsData for 4589 certified deaths due to PD as the underlying cause of death (ICD-10 code: G20) were obtained from the 2008 Japanese vital statistics. Of those, comorbidities listed in the death certificates of 477 randomly selected decedents were analyzed. All diseases or conditions mentioned on death certificates were counted and ranked in descending order of frequency. The death rates (per 100 000 population) from PD were calculated using Japanese National Vital Statistics. The estimated rate of deaths with PD was extrapolated using US death data from a multiple-cause coding system, as no such system is available in Japan, with adjustment for the difference in disease structure between countries.ResultsAverage age at death was 80.9 years. The top 5 comorbid diseases ranked as contributory causes of death were cerebrovascular diseases (4.0%), dementia (3.8%), diabetes mellitus (3.6%), malignant neoplasm (2.5%), and heart diseases (2.3%). Overall, the death rates from and with PD were 3.6 and 5.8, respectively.ConclusionsAnalysis restricted to data from the underlying-cause coding system underestimated the national burden of PD comorbidity and mortality. Use of death certificates and multiple-cause mortality data complement the existing system.

Trends in Diseases Reported on US Death Certificates That Mentioned HIV Infection, 1996-2006

We examined trends during 1996-2006 in diseases reported on death certificates that mentioned HIV infection. We analyzed multiple-cause mortality data compiled from all US death certificates with any mention of HIV to determine the annual percentages of deaths with various diseases. Deaths reported with HIV during 1996-2006 decreased from 35 340 to 13 750. Standardized percentages of death certificates reporting AIDS-defining opportunistic infections also decreased: pneumocytosis (6.3% to 5.1%), nontuberculous mycobacteriosis (5.5% to 1.8%), cytomegalovirus (5.7% to 1.2%). Non-Hodgkin's lymphoma rose from 4.8% in 1996 to 6.4% in 1997 and declined to 5.0% in 2001, while Kaposi's sarcoma declined from 3.7% in 1996 to 1.7% in 2001; these AIDS-defining cancers had stable percentages after 2001. All other cancers increased during 1996-2006 (2.7% to 7.3%). The percentage of deaths with diseases not specifically attributable to HIV increased: liver disease (5.8% to 13.0%), kidney disease (7.9% to 12.0%), and heart disease (4.9% to 10.2%). Among deaths reported with HIV, the percentages reported with HIV-attributable diseases decreased, while the percentages reported with other diseases increased. Consequently, these other life-threatening diseases need more attention in the management of HIV-infected persons.

Measures of multiple-cause mortality: a synthesis and a notational framework

Over twenty different measures have been used for analyzing multiple-cause mortality data. Various measures are used in the different fields working with multiple-cause data. A review of the literature shows a general lack of standardization in the use of these measures and a lack of a notational framework for developing formulae for the different measures. This paper aims to make contributions towards closing these two gaps. It provides a synthesis of the literature on different measures and outlines a notational framework for developing multiple-cause mortality measures.

Mortality due to Influenza in the United States—An Annualized Regression Approach Using Multiple-Cause Mortality Data

Influenza is an important cause of mortality in temperate countries, but there is substantial controversy as to the total direct and indirect mortality burden imposed by influenza viruses. The authors have extracted multiple-cause death data from public-use data files for the United States from 1979 to 2001. The current research reevaluates attribution of deaths to influenza, by use of an annualized regression approach: comparing measures of excess deaths with measures of influenza virus prevalence by subtype over entire influenza seasons and attributing deaths to influenza by a regression model. This approach is more conservative in its assumptions than is earlier work, which used weekly regression models, or models based on fitting baselines, but it produces results consistent with these other methods, supporting the conclusion that influenza is an important cause of seasonal excess deaths. The regression model attributes an annual average of 41,400 (95% confidence interval: 27,100, 55,700) deaths to influenza over the period 1979-2001. The study also uses regional death data to investigate the effects of cold weather on annualized excess deaths.

Kidney disease and arthritis in a cohort study of workers exposed to silica.

Silica exposure has been associated with kidney disease and rheumatoid arthritis; an autoimmune mechanism has been proposed. Approximately 2 million people are occupationally exposed to silica in the United States, 100,000 at more than twice the National Institute for Occupational Safety and Health recommended exposure limit of 0.05 mg/m(3). We examined renal disease morbidity and mortality, as well as arthritis mortality, in a cohort of 4,626 silica-exposed workers in the industrial sand industry (an industry previously unstudied). We compared the cohort with the U.S. population and also conducted internal exposure-response analyses using a job-exposure matrix based on more than 4,000 industrial hygiene samples. We found excess mortality from acute renal disease [standardized mortality ratio (SMR) = 2.61, 95% confidence intervals (95% CIs) = 1.49--4.24; 16 deaths], chronic renal disease (SMR = 1.61, 95% CI = 1.13--2.22; 36 deaths), and arthritis (SMR = 4.36, 95% CI = 2.76--6.54; 23 deaths) on the basis of multiple-cause mortality data, which considered any mention of disease on a death certificate. Linking the cohort with the U.S. registry of end-stage renal disease for the years 1977-1996, we found an excess of end-stage renal disease incidence (standardized incidence ratio = 1.97, 95% CI = 1.25--2.96; 23 cases), which was highest for glomerulonephritis (standardized incidence ratio = 3.85, 95% CI = 1.55--7.93; 7 cases). We found increasing end-stage renal disease incidence with increasing cumulative exposure; standardized rate ratios by quartile of cumulative exposure were 1.00, 3.09, 5.22, and 7.79. A positive exposure-response trend was also observed for rheumatoid arthritis on the basis of death certificate data. These data represent the largest number of kidney disease cases analyzed to date in a cohort with well-defined silica exposure and suggest a causal link between silica and kidney disease. Excess risk of end-stage renal disease due to a lifetime of occupational exposure at currently recommended limits is estimated to be 14%, above a background end-stage renal disease risk of 2%.

Hemochromatosis-associated mortality in the United States from 1979 to 1992: an analysis of Multiple-Cause Mortality Data.

Hemochromatosis, which can lead to serious chronic diseases resulting from iron overload, has an estimated prevalence of 50 to 80 cases per 10000 persons. However, little population-based information is available on the impact of hemochromatosis on morbidity and mortality. To evaluate trends over 14 years in deaths and medical conditions associated with hemochromatosis in the United States. We searched Multiple-Cause Mortality Files compiled by the National Center for Health Statistics for the years 1979 to 1992 for all records listing hemochromatosis. We used these data to calculate age-adjusted and age-specific mortality rates, identify medical conditions associated with a known diagnosis of hemochromatosis at death, and calculate proportionate mortality ratios for these medical conditions. The listing of hemochromatosis on death certificates increased 60% from 1979 to 1992. Decedents with hemochromatosis were 23, 13, and 5 times more likely to have liver neoplasms, liver disease, and cardiomyopathy, respectively, than were decedents without hemochromatosis. Conversely, decedents with liver neoplasms, liver disease, and cardiomyopathy were 26, 14, and 5 times more likely, respectively, to have hemochromatosis than were decedents without these conditions. Hemochromatosis was 82 times more likely in persons with the combination of liver neoplasms and diabetes and 43 times more likely in those with the combination of liver disease and diabetes than in those without these conditions. Comparison of the reported prevalence of hemochromatosis among decedents with estimates of prevalence in the general U.S. population suggests that either the penetrance or the recognition of hemochromatosis, or both, is low. Nevertheless, substantial mortality resulting from liver disease, liver neoplasms, cardiomyopathy, and a combination of liver disease and diabetes in patients with hemochromatosis argues for the improved diagnosis and treatment of hemochromatosis in persons with these conditions.

Lung cancer deaths in the United States from 1979 to 1992: an analysis using multiple-cause mortality data.

We sought to describe trends in the presence of lung cancer at the time of death in the United States from 1979 to 1992. We analysed death certificate reports in the Multiple-Cause Mortality Files compiled by the National Center for Health Statistics, searching for any mention of lung cancer, lung cancer as the underlying cause of death, and comorbid conditions. Of the 29,042,213 decedents in the study period, 1,892,129 (6.5%) had a diagnosis of lung cancer listed on their death certificates; of these 1,892,129 decedents, 1,734,767 (91.7%) had lung cancer listed as the underlying cause of death. Decedents with lung cancer listed as being present but not the underlying cause of death were more likely to be male (relative risk [RR] 1.16, 95% confidence interval [CI]: 1.15-1.17), and older (RR 4.61, 95% CI: 4.35-4.88 for decedents older than 85 compared to those aged less than 44), but less likely to be black than white (RR 0.88, 95% CI: 0.87-0.90). The mortality rate, age-adjusted to the 1980 population, increased 23.0%, from 47.9 per 100,000 in 1979 to 58.9 per 100,000 in 1992. Over the study period, black men had the highest mortality rates (117.3-125.2 per 100,000), followed by white men (81.7-88.7 per 100,000), men of other races (37.4-46.7 per 100,000), white women (22.1-39.1 per 100,000), black women (21.4-38.2 per 100,000), and women of other races (12.6-18.1 per 100,000). Age-adjusted, state specific rates varied threefold, from 30.4 per 100,000 in Utah to 93.9 per 100,000 in Nevada. We conclude that the underlying cause of death data base, which captures almost 92% of decedents with lung cancer present, accurately tracks lung cancer mortality trends in the US. Mortality rates of lung cancer, which are decreasing among men, continue to increase among women.

Trends and patterns of mortality associated with birth defects and genetic diseases in the United States, 1979-1992: an analysis of multiple-cause mortality data.

Contemporary information on the trends and patterns of mortality associated with birth defects and genetic diseases is lacking in the United States. To study these trends and patterns, we used the Multiple-Cause Mortality Files of the National Center for Health Statistics. From 1979 through 1992, 320,208 deaths in the United States were associated with birth defects and genetic diseases. The age-adjusted mortality rates for people with birth defects declined from about 8.2/100,000 in 1979 to about 6.7/100,000 in 1992, and the mortality rates for people with genetic diseases increased from 2.2/100,000 in 1979 to 2.5/100,000 in 1992. The mortality rate was higher among men than among women and higher among blacks than among whites or other races for both birth defect- and genetic disease-associated deaths. The rate among infants with birth defects was more than 25 times higher than that among other age groups. About half of the children whose deaths were associated with birth defects had cardiovascular system defects, 15% had central nervous system defects, and 12% had chromosomal defects. For deaths associated with genetic diseases, hereditary neurologic or storage disorders were the most common genetic diseases (38%), followed by metabolic disorders (21%), sickle cell and thalassemia (12%). The decline in the rate of mortality from birth defects in the United States probably reflects improvements in medical and surgical care and other factors. Most of the mortality associated with birth defects remains in the pediatric age group (less than 15 years old). The upward trend we detected for the deaths with genetic diseases was most likely related to improved recognition and reporting of some genetic diseases rather than to the increased prevalence.

Pulmonary fibrosis deaths in the United States, 1979-1991. An analysis of multiple-cause mortality data.

We sought to describe pulmonary fibrosis mortality in the United States from 1979 through 1991 by analyzing death certificate reports compiled by the National Center for Health Statistics. Of the 26,866,600 people who died during the study period, 107,292 had a diagnosis of pulmonary fibrosis listed on their death certificates. Among men, age-adjusted mortality rates increased from 48.6 per 1,000,000 in 1979 to 50.9 per 1,000,000 in 1991 and, among women, these rates increased from 21.4 per 1,000,000 in 1979 to 27.2 per 1,000,000 in 1991. Among both men and women rates were higher in older age strata than in younger age strata. Age-adjusted mortality rates were consistently higher among whites and people of races than blacks. The frequency with which pulmonary fibrosis was listed as the underlying cause of death increased from 40% in 1979 to 56% in 1991. Age-adjusted mortality rates varied by state, with lowest rates in the Midwest and Northeast, and the highest rates in the West and Southeast. We conclude that the age-adjusted rate of pulmonary fibrosis among decedents in the United States increased, and pulmonary fibrosis was listed as the underlying cause of death with increasing frequency, over the study period. We cannot determine whether the differences we detected between regions, sexes, and races are related to characteristics of the disease or problems in death certification and coding.

Trends in infectious diseases and cancers among persons dying of HIV infection in the United States from 1987 to 1992.

To determine trends in the relative frequency of infectious diseases and cancers among U.S. residents dying of human immunodeficiency virus (HIV) infection. National multiple-cause mortality data for 1987 to 1992 compiled from death certificates. Deaths reported with HIV infection as the underlying cause and with nonunderlying causes that could be secondary to HIV infection. Trends in the annual percentage of deaths associated with each infectious disease or cancer that accounted for at least 1.0% of all HIV-related deaths. From 1987 to 1992, the percentage of HIV-related deaths associated with the following diseases decreased: pneumocystosis, from 32.5% to 13.8%; cryptococcosis, from 7.7% to 5.0%; and candidiasis, from 2.3% to 1.7%. The percentage of deaths associated with the following diseases increased: nontuberculous mycobacteriosis, from 6.7% to 12.2%; cytomegalovirus disease, from 5.2% to 9.9%; bacterial septicemia, from 9.0% to 11.5%; non-Hodgkin lymphoma, from 3.9% to 5.7%; tuberculosis, from 2.9% to 4.1%; progressive multifocal leukoencephalopathy, from 0.8% to 1.9%; bacterial pneumonia, from 1.2% to 2.1%; and cryptosporidiosis or isosporiasis, from 0.7% to 1.2%. The percentages of deaths associated with toxoplasmosis, Kaposi sarcoma, and pneumonia caused by unspecified organisms had no significant linear trends (ranges from 4.9% to 5.5%, 10.4% to 12.1%, and 17.6% to 18.6%, respectively). The percentage of HIV-related deaths associated with pneumocystosis has decreased dramatically, probably because of chemoprophylaxis and improved treatment. Pneumonia caused by unspecified organisms has now become the leading secondary cause of death among persons dying of HIV infection. Decreases in the percentages of HIV-related deaths associated with cryptococcosis and candidiasis may reflect the use of new antifungal agents such as fluconazole.

Emergence of diabetes mellitus in a Mexican‐origin population: A multiple cause‐of‐death analysis

The "New World syndrome" is comprised of disorders that are hypothesized to have resulted from an interaction of the Amerindian genotype with an environment that includes marked changes in lifestyle and diet. The principal component of the syndrome is adult-onset (noninsulin dependent) diabetes mellitus. The purpose of this paper is to describe the emergence of diabetes in a Mexican-origin population. Using a unique file of multiple-cause mortality data, we have computed standardized mortality ratios and relative standardized mortality ratios for Mexican-origin individuals and for other white persons age 30 and over from the 1930's through the middle 1980's. Results for the study population residing in Bexar County (San Antonio), Texas, show that diabetes mortality for Mexican-origin individuals did indeed increase in a pattern consistent with the New World syndrome hypothesis. This study is the first description of the emergence of diabetes using a data set with consistently defined causes of death and demographic characteristics.

Trends in Death With Tuberculosis During the AIDS Era

To describe and analyze recent changes in tuberculosis mortality in the United States during the acquired immunodeficiency syndrome (AIDS) epidemic. We used National Center for Health Statistics multiple-cause mortality data and analyzed deaths with tuberculosis (1980 through 1990) and/or AIDS (1987 through 1990) as an underlying or associated cause. We also categorized the 50 states and the District of Columbia into high (five states), medium (23 states), and low (23 states) AIDS incidence groups and then compared the groups' rates of death with tuberculosis during the period 1980 through 1990. Residents of the United States who died in the period 1980 through 1990. Death certificates indicating AIDS and/or tuberculosis. A bimodal age distribution of persons dying with tuberculosis has emerged concurrent with the AIDS epidemic. A new peak spanning the ages 20 to 49 years accompanies the preexisting peak in the elderly. In 1990, 54.2% (729/1344) of the deaths with tuberculosis in persons 20 to 49 years of age occurred in persons who also had AIDS listed on their death certificates. During the period 1987 through 1990, there was an increasing trend in the proportion of AIDS deaths that also had tuberculosis: 2.3% (353/15,075) in 1987, 2.5% (460/18,649) in 1988, 3.0% (738/24,607) in 1989, and 3.0% (836/27,975) in 1990 (P < .001). Of AIDS deaths in 1990, 1.6% (253/15,565) of whites died with tuberculosis, compared with 4.7% (400/8533) of blacks (P < .001) and 4.7% (172/3666) of Hispanics (P < .001). In the high AIDS incidence states, the rate of death with tuberculosis in persons aged 20 to 49 years rose from 0.61 to 2.82 per 100,000 population in the period 1982 through 1990, an increase of 362%. For this age group in the states with medium and low AIDS incidence, the rates of death with tuberculosis during this period rose 52% and 47% (from 0.44 to 0.67 and from 0.19 to 0.28 per 100,000 population), respectively. The increases in the rate of death with tuberculosis within all three groups and the differences among the groups were all highly statistically significant (P < .001). The AIDS epidemic has significantly increased the number and rate of tuberculosis deaths in younger adults through 1990, although in this study discrimination of deaths due to tuberculosis from deaths with tuberculosis was not possible. Vigorous efforts to prevent and treat tuberculosis and AIDS are indicated to reverse the trends we have described.
