Before advances in therapy, public health surveillance of acquired immunodeficiency syndrome (AIDS) provided reliable population-based information that represented trends in the incidence of human immunodeficiency virus (HIV) infection. However, since 1996, highly active antiretroviral therapy (HAART) has prolonged substantially the interval between the diagnosis of HIV infection and the development of AIDS, which has diminished the capacity of AIDS surveillance alone to monitor the underlying patterns of HIV transmission. As a result, CDC recommends that states conduct HIV-infection reporting in addition to AIDS surveillance. This report describes trends in newly diagnosed cases of HIV infection in 25 states that conducted name-based HIV/AIDS surveillance during 1994-2000. The findings indicate that the number of diagnosed HIV infections declined in these states during 1994-1997 and remained constant during 1998-2000. HIV/AIDS surveillance should be conducted by all states to fully characterize persons infected with HIV who need treatment and prevention services.  相似文献

Obesity in persons with diabetes is associated with poorer control of blood glucose levels, blood pressure, and cholesterol, placing persons with diabetes at higher risk for both cardiovascular and microvascular disease. Conversely, intentional weight loss is associated with reduced mortality among overweight persons with diabetes. CDC analyzed the prevalence of overweight and obesity among U.S. adults aged >/=20 years with previously diagnosed diabetes by using data from two surveys: the Third National Health and Nutrition Examination Survey (NHANES III), 1988-1994, and NHANES 1999-2002. This report summarizes the results of that analysis, which indicated that most adults with diagnosed diabetes were overweight or obese. During 1999-2002, the prevalence of overweight or obesity was 85.2%, and the prevalence of obesity was 54.8%. Encouraging patients to achieve and maintain a healthy weight should be a priority for all diabetes-care programs.  相似文献

In 2001, suicide was the third leading cause of death among persons aged 10-19 years. The most common method of suicide in this age group was by firearm (49%), followed by suffocation (mostly hanging) (38%) and poisoning (7%). During 1992-2001, although the overall suicide rate among persons aged 10-19 years declined from 6.2 to 4.6 per 100,000 population, methods of suicide changed substantially. To characterize trends in suicide methods among persons in this age group, CDC analyzed data for persons living in the United States during 1992-2001. This report summarizes the results of that analysis, which indicated a substantial decline in suicides by firearm and an increase in suicides by suffocation in persons aged 10-14 and 15-19 years. Beginning in 1997, among persons aged 10-14 years, suffocation surpassed firearms as the most common suicide method. The decline in firearm suicides combined with the increase in suicides by suffocation suggests that changes have occurred in suicidal behavior among youths during the preceding decade. Public health officials should develop intervention strategies that address the challenges posed by these changes, including programs that integrate monitoring systems, etiologic research, and comprehensive prevention activities.  相似文献

OBJECTIVES: Because of limited reporting of HIV status in case reports to the national tuberculosis (TB) surveillance system, the authors conducted this study to estimate the proportion of US TB cases with HIV co-infection and to describe demographic and clinical characteristics of co-infected patients. METHODS: The 50 states, New York City, and Puerto Rico submitted the results of cross-matches of TB registries and HIV-AIDS registries. The authors determined the number of TB cases reported for 1993-1994 that were listed in HIV-AIDS registries and analyzed data on demographic and clinical characteristics by match status. RESULTS: Of 49,938 TB cases reported for 1993-1994, 6863 (14%) were listed in AIDS or HIV registries. The proportions of TB-AIDS cases among TB cases varied by reporting area, from 0% to 31%. Anti-TB drug resistance was higher among TB-AIDS cases, particularly resistance to isoniazid and rifampin (multidrug resistance) and rifampin alone, In some areas with low proportions of multidrug-resistant TB cases, however, the difference in multidrug resistance between TB-AIDS patients and non-AIDS TB patients was not found. CONCLUSIONS: The proportion of TB cases with HIV co-infection, particularly in some areas, underscores the importance of the HIV-AIDS epidemic for the epidemiology of TB. Efforts to improve HIV testing as well as reporting of HIV status for TB patients should continue to ensure optimum management of coinfected patients, enhance surveillance activities, and promote judicious resource allocation and targeted prevention and control activities.  相似文献

Giardiasis surveillance--United States, 1992-1997.   总被引:7,自引:0,他引:7  
PROBLEM/CONDITION: Giardia intestinalis, the organism that causes the gastrointestinal illness giardiasis, is the most commonly diagnosed intestinal parasite in public health laboratories in the United States. In 1992, the Council of State and Territorial Epidemiologists assigned giardiasis an event code that enabled states to begin voluntarily reporting surveillance data on giardiasis to CDC. REPORTING PERIOD: This report includes data that were reported from January 1992 through December 1997. DESCRIPTION OF THE SYSTEM: The National Giardiasis Surveillance System includes data about reported cases of giardiasis from participating states. Because most states were already collecting data on occurrence of giardiasis, the assignment of an event code to giardiasis has allowed voluntary reporting of these data to CDC via the National Electronic Telecommunications System for Surveillance. RESULTS: Since 1992, the number of states reporting cases of giardiasis to CDC has risen from 23 to 43. The annual number of giardiasis cases reported has ranged from 12,793 in 1992 to 27,778 in 1996. In 1997, cases per 100,000 state population ranged from 0.9 to 42.3, with 10 states reporting >20.0 cases per 100,000 population and a national average of 9.5 cases per 100,000 population. In 1997, New York State, including New York City, reported the highest number of cases (3,673, or 20.3 cases per 100,000 population), accounting for 14.5% of cases nationally; however, Vermont reported the highest incidence rate in 1997 (42.3 cases per 100,000 population). Both states have active surveillance systems in place for giardiasis. Cases have an approximately equal sex distribution. Nationally, rates were the highest among children aged 0-5 years, followed closely by persons aged 31-40 years. In these two age groups, most cases were reported during late summer and early fall--an indication that transmission occurred during the summer. INTERPRETATION: This report documents the first nationwide look at epidemiologic parameters and disease burden estimates for giardiasis in the United States. Transmission occurs in all major geographic areas of the country. The seasonal peak in age-specific case reports coincides with the summer recreational water season and might reflect the heavy use by young children of communal swimming venues (e.g., lakes, rivers, swimming pools, and water parks)--a finding consistent with Giardia's low infectious dose, the high prevalence of diaper-aged children in swimming venues, the extended periods of cyst shedding that can occur, and Giardia's environmental resistance. Estimates based on state surveillance data indicate that as many as 2.5 million cases of giardiasis occur annually in the United States. PUBLIC HEALTH ACTION: Giardiasis surveillance provides data to educate public health practitioners and health-care providers about the scope and magnitude of giardiasis in the United States. These data can be used to establish research priorities and to plan future prevention efforts.  相似文献

PROBLEM/CONDITION: Despite the widespread availability of a safe and effective vaccine against tetanus, 201 cases of the disease were reported during 1991-1994. Of patients with known illness outcome, the case-fatality rate was 25%. REPORTING PERIOD COVERED: 1991-1994. DESCRIPTION OF SYSTEM: Physician-diagnosed cases of tetanus are reported to local and state health departments, the latter of which reports these cases on a weekly basis to CDC's National Notifiable Disease Surveillance System. Since 1965, state health departments also have submitted supplemental clinical and epidemiologic information to CDC's National Immunization Program. RESULTS: During 1991-1994, 201 cases of tetanus were reported from 40 states, for an average annual incidence of 0.02 cases per 100,000 population. Of the 188 patients for whom age was known, 101 (54%) were aged > or = 60 years and 10 (5%) were aged < 20 years. No cases of neonatal tetanus were reported. Among adults, the risk for tetanus increased with age; the risk for persons aged > or = 80 years was more than 10 times greater than the risk for persons aged 20-29 years. All deaths occurred among persons aged > or = 30 years. The case-fatality rate (overall: 25%) increased with age, from 11% in persons aged 30-49 years to 54% in persons aged > or = 80 years. Only 12% of all patients were reported to have received a primary series of tetanus toxoid before onset of illness. For 77% of patients, tetanus occurred after an acute injury was sustained. Of patients who obtained medical care for their injury, only 43% received tetanus toxoid as part of wound prophylaxis. INTERPRETATION: The epidemiology of reported tetanus in the United States during 1991-1994 was similar to that during the 1980s. Tetanus continued to be a severe disease primarily of older adults who were unvaccinated or inadequately vaccinated. Most tetanus cases occurred after an acute injury was sustained, emphasizing the need for appropriate wound management. ACTIONS TAKEN: In addition to decennial booster doses of tetanus-diphtheria toxoid during adult life, the Advisory Committee on Immunization Practices (ACIP) recommends vaccination visits for adolescents at age 11-12 years and for adults at age 50 years to enable health-care providers to review vaccination histories and administer any needed vaccine. Full implementation of the ACIP recommendations should virtually eliminate the remaining tetanus burden in the United States.  相似文献

This study measured the migration of persons with the acquired immunodeficiency virus (AIDS) between diagnosis and death using AIDS case and death reports from 12 states for 1985 to 1992. Of 49,805 persons with AIDS, 10.6% changed their place of residence, and half of these individuals who moved changed their state of residence. Migration had relatively little impact on the numbers of persons with AIDS in the largest metropolitan areas, which accounted for approximately 90% of AIDS diagnoses. Although only 3% of deaths occurred in residents of nonmetropolitan areas, the net effect of migration was a 24% increase in the number of persons with AIDS residing in such areas.  相似文献

BACKGROUND: This paper describes deaths of American workers involving forklifts during the 15-year period from January 1, 1980 to December 31, 1994. METHODS: Death certificate data were obtained from the National Institute for Occupational Safety and Health's (NIOSH's) National Traumatic Occupational Fatality (NTOF) surveillance system. The narrative fields on the death certificate were searched for keywords indicating that a powered industrial vehicle (PIV) or forklift was involved in the death. This study examined the circumstances of the forklift-related deaths, the nature of the injury, and the decedent's age, gender, race, occupation, and industry. Average annual employment data from the Bureau of the Census were used to calculate civilian fatality rates by age, gender, industry, and occupation. RESULTS: A total of 1,021 deaths were identified. The average age of the fatally injured worker was 38 years; the 1,021 forklift-related deaths resulted in a total of 27,505 years of productive life lost. The three most common circumstances of the fatalities were forklift overturns (22%), pedestrian struck by forklifts (20%), and worker crushed by forklift (16%). The greatest proportion of the fatalities (37%) occurred to workers in Manufacturing, followed by Transportation, Communication, and Public Utilities, (TCPU), (17%), Construction (16%), Wholesale Trade (8%), and Agriculture, Forestry, and Fishing (AFF) (7%). The highest forklift-related fatality rates per ten million workers occurred among transport operatives (34.0) and laborers (32.0). CONCLUSIONS: Many of the fatalities resulting from forklift "overturns" might have been prevented if the operator had been restrained with a lap/shoulder belt. Careful consideration should be given to separating pedestrian and forklift traffic, and restricting the use of forklifts near time clocks, exits, and other areas where large numbers of pedestrians pass through an area in a short time. Additionally, systematic traffic control, including rules for pedestrian and forklift traffic, will be necessary to reduce the enormous injury and death toll associated with forklifts. Am. J. Ind.

This study estimated the incidence of clinical neonatal seizures among infants born between 1992 and 1994 in Harris County, Texas, a county with a large and ethnically diverse population. Infants with neonatal seizures were ascertained from four sources: hospital discharge diagnoses, birth certificates, death certificates, and a study of neonatal seizures conducted concurrently with this study at a large tertiary care center in Houston, Texas. There were 207 cases of clinical neonatal seizures among 116,048 live births (an incidence of 1.8 per 1,000 live births). The incidence was highest among infants weighing less than 1,500 g (19/1,000) and decreased as birth weight increased. There was no significant difference in incidence by ethnicity. Twenty-six percent of the seizures (54/207) occurred after the infants had been discharged from the hospital where they were born. The incidence of neonatal seizures in Harris County was lower than the incidence reported recently for Fayette County, Kentucky, for 1985-1989 (3.5/1,000) and for Newfoundland, Canada, for 1990-1995 (2.5/1,000), but was higher than the incidence estimated for Rochester, Minnesota, for 1935-1984 (1/1,000).  相似文献

Tubal sterilization in the United States, 1994-1996   总被引:3,自引:0,他引:3  
CONTEXT: Although the number and rate of tubal sterilizations, the settings in which they are performed and the characteristics of women obtaining sterilization procedures provide important information on contraceptive practice and trends in the United States, such data have not been collected and tabulated for manyyears. METHODS: Information on tubal sterilizations from the National Hospital Discharge Survey and the National Survey of Ambulatory Surgery was analyzed to estimate the number and characteristics of women having a tubal sterilization procedure in the United States during the period 1994-1996 and the resulting rates of tubal sterilization. These results were compared with those of previous studies to examine trends in clinical setting, in the timing of the procedure and in patient characteristics. RESULTS: In 1994-1996, more than two million tubal sterilizations were performed, for an average annual rate of 1 1.5 per 1,000 women; half were performed postpartum and half were interval procedures (i. e., were unrelated by timing to a pregnancy). All postpartum procedures were performed during inpatient hospital stays, while 96% of interval procedures were outpatient procedures. Postpartum sterilization rates were higher than interval sterilization rates among women 20-29 years of age; interval sterilization procedures were more common than postpartum procedures at ages 35-49. Sterilization rates were highest in the South. For postpartum procedures, private insurance was the expectedprimary source of payment for 48% and Medicaid was expected to pay for 41 %; for interval sterilization procedures, private insurance was the expected primary source of payment for 68% and Medicaid for 24%. CONCLUSIONS: Outpatient tubal sterilizations andprocedures using laparoscopy have increased substantially since the last comprehensive analysis of tubal sterilization in 1987, an indication of the effect of technical advances on the provision of this service. Continued surveillance of both inpatient and outpatient procedures is necessary to monitor the role of tubal sterilization in contraceptive practice.  相似文献

Data from the National Hospital Discharge Survey on hospitalizations for acquired immunodeficiency syndrome (AIDS) were analyzed for 1984-85. During 1984, an estimated 10,000 discharges from short-stay hospitals had a diagnosis of AIDS. In 1985, this figure more than doubled to 23,000. Ninety-seven percent of all AIDS discharges were male and 85 per cent were between the ages of 25 and 44. Hospitalizations for AIDS accounted for 510,000 days of hospital care and lasted an average of 15.6 days each.  相似文献

PROBLEM/CONDITION: Influenza epidemics occur nearly every year during the winter months and are responsible for substantial morbidity and mortality in the United States, including an average of approximately 114,000 hospitalizations and 20,000 deaths per year. REPORTING PERIOD: This report summarizes U.S. influenza surveillance data from October 1994 through May 1997, from both active and passive surveillance systems. DESCRIPTION OF SYSTEM: During the period covered, CDC received weekly reports from October through May from a) state and territorial epidemiologists on estimates of local influenza activity, b) approximately 140 sentinel physicians on their total number of patient visits and the number of cases of influenza-like illness (ILI), and c) approximately 70 World Health Organization (WHO) collaborating laboratories in the United States on weekly influenza virus isolations. WHO collaborating laboratories also submitted influenza isolates to CDC for antigenic analysis. Throughout the year, vital statistics offices in 121 cities reported deaths related to pneumonia and influenza (P&I) weekly, providing a measure of the impact of influenza on mortality. RESULTS: During the 1994-95 influenza season, 25 state epidemiologists reported regional or widespread activity at the peak of the season. Cases of ILI reported by sentinel physicians exceeded baseline levels for 4 weeks, peaking at 5%. Influenza A(H3N2) was the most frequently isolated influenza virus type/subtype. The longest period of sustained excess mortality was 5 consecutive weeks, when the percentage of deaths attributed to P&I exceeded the epidemic threshold, peaking at 7.6%. During the 1995-96 season, 33 state epidemiologists reported regional or widespread activity at the peak of the season. ILI cases exceeded baseline levels for 5 weeks, peaking at 7%. Influenza A(H1N1) viruses predominated, although influenza A(H3N2) and influenza B viruses also were identified throughout the United States. P&I mortality exceeded the epidemic threshold for 6 consecutive weeks, peaking at 8.2%. The 1996-97 season was the most severe of the three seasons summarized in this report. Thirty-nine state epidemiologists reported regional or widespread activity at the peak of the season. ILI reports exceeded baseline levels for 5 consecutive weeks, peaking at 7%. The proportion of respiratory specimens positive for influenza peaked at 34%, with influenza A(H3N2) viruses predominating. Influenza B viruses were identified throughout the United States, but only one influenza A(H1N1) virus isolate was reported overall. The proportion of deaths attributed to P&I exceeded the epidemic threshold for 10 consecutive weeks, peaking at 9.1%. INTERPRETATION: Influenza A(H1N1), A(H3N2), and B viruses circulated during 1994-1997. Local surveillance data are important because of geographic and temporal differences in the circulation of influenza types/subtypes. PUBLIC HEALTH ACTIONS: CDC conducts active national surveillance annually from October through May for influenza to detect the emergence and spread of influenza virus variants and monitor the impact of influenza-related morbidity and mortality. Surveillance data are provided weekly throughout the influenza season to public health officials, WHO, and health-care providers and can be used to guide prevention and control activities, vaccine strain selection, and patient care.  相似文献

Diabetes can lead to visual impairment (VI) and blindness (1). However, early detection and treatment of many common eye diseases, such as diabetic retinopathy and glaucoma, can reduce the risk for developing VI (1). Surveillance of VI among persons with diabetes is important for evaluating the effectiveness of efforts to reduce VI and other complications of diabetes. To examine trends in the prevalence of self-reported VI among adults (persons aged ≥18 years) with diagnosed diabetes in the United States and to assess reported access to eye-care providers, CDC analyzed 1997-2010 data from the National Health Interview Survey (NHIS). This report describes the results of that analysis, which indicated that although the number of adults with diagnosed diabetes reporting VI increased, the age-adjusted percentage of adults with diagnosed diabetes who reported VI declined significantly, from 23.7% in 1997 to 16.7% in 2010. During this 14-year period, age-adjusted VI prevalence declined significantly among most categories of adults with diabetes: men, women, whites, Hispanics, those with some college or higher education, and those diagnosed with diabetes for ≥3 years. Prevalence also declined among those aged ≥45 years. The percentage of adults with diagnosed diabetes and self-reported VI who reported having consulted an eye-care provider in the past year remained constant at approximately 63%. Continued efforts are needed to sustain and improve the declining trends in self-reported VI and to increase rates of recommended eye examinations in the population with diabetes.  相似文献

Equipment that compacts and bales loose solid waste materials into denser, more easilytransported units is common in refuse disposal and recycling and is used routinely at recycling centers, manufacturing facilities, and retail and wholesale stores to compress paper, textiles, metals, plastic, and other material. Persons operating balers and compactors can become caught by the powered rams of the compression chambers while using these machines. Risk factors resulting from these incidents have been identified through surveillance findings and results of investigations conducted by CDC's National Institute for Occupational Safety and Health (NIOSH) Fatality Assessment and Control Evaluation (FACE) program and the Bureau of Labor Statistics Census of Fatal Occupational Injuries (CFOI), a nationwide multisource reporting system for occupational deaths. This report describes the results of two baler and compactor-related investigations conducted during 1992-2000, summarizes surveillance data from 1992 through 1998, which indicated that some employers and workers may have been unaware of the hazards of operating or working near compacting and baling equipment, and suggests safety recommendations for preventing future incidents.  相似文献

During 2007, approximately 110,000 persons in the United States and Puerto Rico began treatment for end-stage renal disease (ESRD) (i.e., kidney failure requiring dialysis or transplantation). Diabetes is the leading cause of ESRD in the United States, accounting for 44% of new cases in 2007. Although the number of persons initiating treatment for kidney failure each year who have diabetes listed as a primary cause (ESRD-D) has increased since 1996, ESRD-D incidence among persons with diagnosed diabetes has declined since 1996. To determine whether this decline occurred in every U.S. region and in every state, CDC analyzed 1996-2007 data from the U.S. Renal Data System (USRDS) and the Behavioral Risk Factor Surveillance System (BRFSS). During the period, the age-adjusted rate of ESRD-D among persons with diagnosed diabetes declined 35% overall, from 304.5 to 199.1 per 100,000 persons with diagnosed diabetes, and declined in all U.S. regions and in most states. No state showed a significant increase in the age-adjusted ESRD-D rate. Continued awareness of risk factors for kidney failure and interventions to improve diabetes care are needed to sustain and improve these trends.  相似文献

Because of aging trends in the US, the number of prevalent colorectal cancer patients is expected to increase. We projected economic burden to the Medicare program and its beneficiaries through the year 2020. Burden was estimated for the initial phase of care, the period following diagnosis, the last year of life, and the continuing phase. Projected burden was evaluated with varying assumptions about incidence, survival, and costs of care. Estimated costs of care in 2000 in the initial, continuing, and last year of life phases of care were approximately $3.18 billion, $1.68 billion, and $2.63 billion, respectively. By the year 2020 under the 'fixed' current incidence, survival, and cost scenario, projected costs for the initial, continuing, and last year of life phases were $4.75 billion, $2.63 billion, and $4.05 billion. Under the current trends scenario (decreasing incidence, improving survival, and increasing costs), costs were $5.19 billion, $3.57 billion, and $5.27 billion. By the year 2020, estimated costs of colorectal cancer care among individuals aged 65 and older increased by 53% in the fixed scenario and by 89% in the current trends scenario. The future economic burden of colorectal cancer to the Medicare program and its beneficiaries in the US will be substantial.  相似文献

Approximately 800,000 firefighters in the United States are volunteer firefighters and 300,000 are career firefighters. Volunteer firefighters primarily serve communities with fewer than 25,000 inhabitants, whereas most career firefighters serve communities of more than 25,000 persons. To characterize fatalities among volunteer and career firefighters, CDC analyzed data from the U.S. Fire Administration (USFA). This report summarizes the results of that analysis and, to illustrate the most common types of volunteer and career firefighter fatalities, describes two cases investigated by the National Institute for Occupational Safety and Health (NIOSH) Firefighter Fatality Investigation and Prevention Program. Fifty-three percent (610 of 1,141) of U.S. firefighters who died while on duty during 1994-2004 were volunteers, and 32% (368) were career firefighters. The remaining 15% (163) of deaths were among other firefighters (e.g., wildland, paid on-call, and part-time paid firefighters). Among volunteer firefighters, sudden cardiac death (e.g., from myocardial infarction or arrhythmia) and motor vehicle (MV) crashes during emergency response were the leading causes of fatality. Among career firefighters, sudden cardiac death and asphyxiation were leading causes of death. Adoption and enforcement of existing fire-service recommendations regarding fitness standards, mandatory medical evaluations with appropriate work restrictions, and emergency vehicle response protocols are needed to prevent these fatalities among firefighters.  相似文献
