Annual summary of vital statistics: trends in the health of Americans during the 20th century.

The overall improvement in the health of Americans over the 20th century is best exemplified by dramatic changes in 2 trends: 1) the age-adjusted death rate declined by about 74%, while 2) life expectancy increased 56%. Leading causes of death shifted from infectious to chronic diseases. In 1900, infectious respiratory diseases accounted for nearly a quarter of all deaths. In 1998, the 10 leading causes of death in the United States were, respectively, heart disease and cancer followed by stroke, chronic obstructive pulmonary disease, accidents (unintentional injuries), pneumonia and influenza, diabetes, suicide, kidney diseases, and chronic liver disease and cirrhosis. Together these leading causes accounted for 84% of all deaths. The size and composition of the American population is fundamentally affected by the fertility rate and the number of births. From the beginning of the century there was a steady decline in the fertility rate to a low point in 1936. The postwar baby boom peaked in 1957, when 123 of every 1000 women aged 15 to 44 years gave birth. Thereafter, fertility rates began a steady decline. Trends in the number of births parallel the trends in the fertility rate. Beginning in 1936 and continuing to 1956, there was precipitous decline in maternal mortality from 582 deaths per 100 000 live births in 1935 to 40 in 1956. Since 1950 the maternal mortality ratio dropped by 90% to 7.1 in 1998. The infant mortality rate has shown an exponential decline during the 20th century. In 1915, approximately 100 white infants per 1000 live births died in the first year of life; the rate for black infants was almost twice as high. In 1998, the infant mortality rate was 7.2 overall, 6.0 for white infants, and 14.3 for black infants. For children older than 1 year of age, the overall decline in mortality during the 20th century has been spectacular. In 1900, >3 in 100 children died between their first and 20th birthday; today, <2 in 1000 die. At the beginning of the 20th century, the leading causes of child mortality were infectious diseases, including diarrheal diseases, diphtheria, measles, pneumonia and influenza, scarlet fever, tuberculosis, typhoid and paratyphoid fevers, and whooping cough. Between 1900 and 1998, the percentage of child deaths attributable to infectious diseases declined from 61.6% to 2%. Accidents accounted for 6.3% of child deaths in 1900, but 43.9% in 1998. Between 1900 and 1998, the death rate from accidents, now usually called unintentional injuries, declined two-thirds, from 47. 5 to 15.9 deaths per 100 000. The child dependency ratio far exceeded the elderly dependency ratio during most of the 20th century, particularly during the first 70 years. The elderly ratio has gained incrementally since then and the large increase expected beginning in 2010 indicates that the difference in the 2 ratios will become considerably less by 2030. The challenge for the 21st century is how to balance the needs of children with the growing demands for a large aging population of elderly persons.

Race/ethnicity and the 2000 census: implications for public health.

OBJECTIVES: This article addresses the potential impact of the revised standards for race and ethnicity on data from the 2000 census and public health data sources, policies, and programs. METHODS: The authors examine the relationship between race/ethnicity and health in selected measures, identify the factors that influence race/ethnicity identification, consider past experience in race/ethnicity reporting, and explore the challenges in understanding and managing the effects of new racial/ethnic categories in various data sets. RESULTS: The multiple-race group seems to compose only a small percentage of the US population and may have little impact on data for single-race groups. Actual effects will vary according to a number of factors, including the size, composition, and geographic distribution of the group. CONCLUSIONS: More research is needed to support a thorough understanding of the reporting of multirace data and the development of techniques for analyzing these data. Given the importance of understanding the relationship between race/ethnicity and health, the ability to produce useful, comparable, and meaningful data is essential.

Cancer surveillance in the U.S.: can we have a national system?

Cancer-related services are consuming ever-increasing health resources; along with this trend, health care costs are rising. As health care planners, researchers, and policymakers formulate strategies to meet this challenge, they are looking to cancer registries and the health information system built around them as collectors of the most extensive information regarding cancer treatment in the U.S. Currently, there are multiple programs collecting and reporting data regarding cancer incidence, morbidity, mortality, and survival. This report profiles cancer surveillance efforts in the U.S. and describes the National Coordinating Council for Cancer Surveillance, which was organized in 1995 to facilitate a collaborative approach among the organizations involved.

Breast cancer trends. Incidence, mortality, and survival.

This paper describes trends in the primary measures of breast cancer. Data on incidence and mortality are drawn from the Surveillance, Epidemiology, and End Results Program, and those on mortality are from the National Center for Health Statistics. There has been a steady increase in the rate of breast cancer cases since 1950, with a sharp rise in the 1980s because of the increased use of mammography. Conversely, mortality since 1973 has declined by 11% for women younger than 50 (the decrease is primarily in the 70s) and increased by 6% for women aged 50 and older. There are different racial experiences in breast cancer incidence, with African-American women aged 40 and older having a lower incidence rate, and those younger than 40 having a higher one. For all ages, there is a greater likelihood of mortality (lower survival) for each case. This paper explores these trends and their implications for the future impact of this disease.

Accrual of patients to randomized clinical trials. Factors affecting cancer prevention and control research.

Clinical judgment is increasingly being challenged by the need for randomized clinical trials. The 1987 National Cancer Institute mandate--that the Community Clinical Oncology Program (CCOP) accrue patients to cancer control protocols--provided an opportunity to examine the factors that affect accrual performance. An analysis of 52 CCOPs and their research bases participating in the program found that the availability of protocols, involvement with research base activities, a demonstrated link to community physicians (particularly those physicians, such as surgeons, who had access to patients), and the use of personal contacts to inform non-CCOP physicians about CCOP activities were important facilitating factors for accruing patients to cancer prevention and control trials.

Trends in cancer mortality in 15 industrialized countries, 1969-1986.

BACKGROUND: Assessing trends in cancer provides a means for gauging progress against the disease, estimating future demands for care and treatment, and suggesting clues about shifting causal factors that may account for the more recent changes. PURPOSE: This study was designed to evaluate trends in the major sites of cancer associated with high mortality rates in 15 industrialized countries. To highlight differences among regions, we grouped these countries into six geographic areas: United States, Eastern Europe, Western Europe, East Asia, Oceania, and Nordic countries. In addition, cancer mortality trends in these regions were compared with incidence patterns in the United States. METHODS: Data provided by the World Health Organization were used to evaluate age-specific mortality trends from 1969 through 1986 for lung, breast, prostate, stomach, and colorectal cancers and for all other sites considered as a group. We also assembled and analyzed data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute for the same sites and age groups from 1973 through 1986. RESULTS: Over the period 1969 through 1986, recorded cancer mortality in persons aged 45 years and older in the six regions studied has increased for lung, breast, and prostate cancers in most age groups, while the decline in stomach cancer mortality is substantial. The increase in lung cancer deaths in men aged 45-54 years has slowed greatly or reversed in all areas except Eastern Europe and East Asia. Trends for intestinal cancer vary by age and region. For all other sites considered as a group, increases have occurred for persons older than 64 years in most regions. In Eastern Europe, there are disturbingly high rates and rapid increases for several of the major forms of cancer in persons aged 45-54 years. In general, trends for cancer incidence in the United States parallel those for mortality. For intestinal cancer, however, incidence has increased while mortality has declined. CONCLUSIONS: The trends we report cannot be explained solely by changes in cigarette smoking or aging. Other causes of changes in cancer incidence and mortality need to be determined. IMPLICATIONS: The increasing and decreasing trends in mortality from and incidence of cancer that we found are important for health care planning and may also suggest opportunities for research in cancer prevention.

Projections of the incidence of non-Hodgkin's lymphoma related to acquired immunodeficiency syndrome.

Advances in antiretroviral therapy and treatment or prophylaxis against opportunistic infection have resulted in prolongation of the survival of patients with acquired immunodeficiency syndrome (AIDS). Previous research has demonstrated an association between AIDS and risk of non-Hodgkin's lymphoma (NHL). In addition to the approximately 3% of individuals found to have NHL at the time of AIDS onset, others continue to develop NHL following AIDS diagnosis. Data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute demonstrated a sharply increasing incidence of NHL among men in the age range 20-49 years since 1983 in the United States. Based on new data on the risk of NHL following AIDS diagnosis, on estimates of improved survival following AIDS diagnosis, and on projections of future AIDS incidence, we considered four sets of assumptions and estimated the number of AIDS-related NHL cases in 1992 to be between 2900 and 9800. Three of these projections were higher than the estimate of 4700 cases obtained by linear extrapolation of SEER incidence trends. These projections of AIDS-related NHL incidence suggest that between 8% and 27% of all NHL cases that occur in the United States in 1992 will arise as a consequence of infection with the human immunodeficiency virus (HIV), imposing a substantial health care burden. More research into the pathogenesis of lymphoma and new approaches to antiretroviral and antilymphoma therapy will be necessary to prevent and treat this formidable complication of infection with HIV.

Evaluating organizational design to assure technology transfer: the case of the Community Clinical Oncology Program.

Current theories of organizational performance are used to guide researchers at the Health Services Research Center of the University of North Carolina at Chapel Hill and the University of Illinois Survey Research Laboratory in the evaluation of the National Cancer Institute's Community Clinical Oncology Program (CCOP) and to derive policy options to enhance program operations. CCOP represents an innovative mechanism designed to improve the accrual of patients to phase III clinical trials, involve community-based oncologists in clinical research, and potentially to disseminate new information on the state-of-the-art cancer treatment to areas distant from cancer centers and research-oriented medical centers. Examined in this evaluation of the second phase of the CCOP are the ability of the 52 currently funded CCOPs and 17 research bases to accrue patients to cancer treatment and cancer control research protocols, their influence on the patterns of practice for cancer treatment in CCOP communities, and their influence on cancer control awareness and activity among primary care physicians. The evaluation applies selected organizational perspectives to describe the intraorganizational and interorganizational characteristics of the CCOPs, research bases, and the Institute that may affect the performance of the CCOP. This organizational approach relates the accrual and influence of the CCOP to controllable aspects of the program's design and management strategies that can be changed through policies directed by the National Cancer Institute. These policies include the criteria used to select CCOPs, the role of research bases in the development and implementation of treatment and cancer control research protocols, and the use of accrual credits.

Person-years of life lost due to cancer in the United States, 1970 and 1984.

The number of deaths due to cancer in the United States reached an all-time high of 453,450 deaths in 1984 and, due to the dynamics of population growth, will continue to increase if the risk of dying from cancer does not change. Between 1970 and 1984, the total Person-Years of Life Lost (PYLL), the sum of the difference between the actual age at death and the expected remaining lifetime for each person who died of cancer, increased for most cancer sites as well as for all sites combined. In 1984, 6,881,281 person-years of life were lost due to cancer deaths, up from 5,303,668 in 1970. The exceptions are those cancers for which there has been major progress in either prevention or treatment; e.g., stomach and cervix uteri (prevention) and testicular, Hodgkin's disease, leukemia, and childhood cancers (treatment). The Average Years of Life Lost (AYLL) per person dying from cancer in 1984 was generally less than in 1970. Overall, each person who died from cancer in 1984 died 15.2 years earlier than his/her life expectancy. The greatest loss was for those who died of childhood cancers (66.9 years earlier), followed by testicular cancer (35.8 years earlier). The least loss relative to the expectation of life was for those who died of prostate cancer. The 25,400 men who died from prostate cancer in 1984 died an average of nine years earlier than otherwise expected.

Cancer control objectives for the year 2000.

A 50% reduction in the cancer mortality rate can be achieved by the year 2000. This is the stated goal of the National Cancer Institute which has set national cancer control objectives focusing on prevention, screening and detection, and treatment. Prevention in terms of reducing tobacco use and modification of diet, and state-of-the-art treatment are expected to bring about the greatest reductions in mortality. This article summarizes the deliberations and recommendations of the NCI's four working groups.
