Behavioral Risk Factor Surveillance System (BRFSS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP).

Mode of Administration

Telephone interview. Interviews for 2004 and later were conducted through computer-assisted telephone interviewing (CATI).

Survey Sample Design

Data collection is conducted separately by each State. Sample design uses State-level, random-digit-dialed probability samples of the adult population (age 18 and over). Most States currently use disproportionate random sampling methods. The BRFSS was initiated in 1984, with 15 States collecting surveillance data on risk behaviors through monthly telephone interviews. The number of States participating in the survey has increased. Since 2001, 50 States, the District of Columbia, Puerto Rico, Guam, and the Virgin Islands have participated in the BRFSS.

Primary Survey Content

The survey consists of a core of questions asked in all States, standardized optional questions on selected topics that are administered at the State's discretion, a rotating core of questions asked every other year in all States, and State-added questions developed to address State-specific needs. Questions cover behavioral risk factors (for example, alcohol and tobacco use), preventive health measures, HIV/AIDS, health status, limitation of activity, and health care access and utilization.

The objective of the BRFSS is to collect uniform, State-specific data on preventive health practices and risk behaviors that are linked to chronic diseases, injuries, and preventable infectious diseases in the adult population.

Population Targeted

U.S. civilian noninstitutionalized population age 18 and over who reside in households with telephones.

Demographic Data

Age, gender, education, race/ethnicity, household income, employment status, marital status.

Years Collected

Since 1984.

Schedule

Annual.

Geographic Estimates

National, State; smaller area estimates possible in some States.

National Ambulatory Medical Care Survey (NAMCS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Field personnel meet with participating office-based physicians and instruct them in survey data collection methods. Physicians are asked to complete a one-page questionnaire (Patient Record Form) on a sample of their office visits during their assigned reporting period.

Survey Sample Design

NAMCS is a national probability sample survey of visits to office-based physicians in the United States. The NAMCS uses a three-stage survey design that involves probability samples of primary sampling units (PSUs), physician practices within PSUs, and patient visits within physician practices. Participating physicians are randomly assigned to a 1-week reporting period during the survey year. A systematic random sample of patient visits during that period is selected, using a visit sampling rate that varies by the size of the practice. The intention is to obtain 30 survey forms per physician. In 2005, 25,665 survey forms were collected.

Primary Survey Content

Information is obtained on various aspects of office visits, including physician practice characteristics, patient characteristics, and other visit characteristics. Only visits to the offices of non-Federal physicians classified by the American Medical Association or the American Osteopathic Association as “office-based, patient care” are included. The survey form is redesigned every 2 to 4 years to address changing health data needs. Among the items collected are patient's age, gender, race, and ethnicity; patient's expressed reason for visiting the physician; intentionality of injury, if any; physician's diagnoses; diagnostic services ordered or provided; therapeutic services; ambulatory surgical procedures performed; medications; providers seen; visit disposition; time spent with physician; and expected source of payment.

Population Targeted

The basic sampling unit is the patient visit. Included in the survey are in-person visits made to the offices of nonfederally employed, office-based physicians who are classified by the American Medical Association or the American Osteopathic Association as being primarily engaged in direct patient care. The specialties of anesthesiology, pathology, and radiology are not included. Also not included are contacts by telephone, visits made outside the physician's office, visits in hospitals or institutional settings, and visits made for administrative purposes only. Sample data are weighted to produce national estimates of office visits.

Demographic Data

Patient's age, gender, race, ethnicity.

Years Collected

Annually from 1973 to 1981; again in 1985; resumed an annual schedule in 1989.

Schedule

Annual.

Geographic Estimates

National, four U.S. Census Bureau regions.

Notes

The NAMCS is a visit-based survey rather than a population-based survey. Therefore, estimates of incidence and prevalence of disease cannot be computed. The survey is cross-sectional in nature. Multiple visits may be made by the same person within the sample.

National Health and Nutrition Examination Survey (NHANES)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

In-person interview in the household and in a private setting at the mobile examination center. Standardized physical examinations and laboratory tests in mobile examination centers.

Survey Sample Design

The NHANES uses a stratified multistage probability sample, nationally representative of the U.S. civilian noninstitutionalized population. The NHANES III survey is designed to be nationally representative for Phase I (1988-1991), Phase II (1991-1994), or the total 6 years (1988-1994) of data collection. People age 5 years and under and those over 59, African Americans, and Mexican Americans were oversampled. In 1999, the NHANES became a continuous survey designed to examine a nationally representative sample of approximately 5,000 people examined at 15 locations each year. From 1999 to 2006, African Americans, Mexican Americans, people with low income, people age 12-19 years, and people age 60 and over were oversampled.

The continuous NHANES is released in 2-year cycles. NHANES 1999-2004 and earlier releases were used for the 2007 NHQR and NHDR. The sample size is smaller than NHANES III, and the number of geographic units in the sample is more limited. The sample design, weighting, and variance estimation methodology also differ from NHANES III. NHANES 2003-2006, the most recent data releases, are incorporated into the 2008 edition of the NHQR and NHDR.

Response Rates (unweighted)

  • NHANES III (1988-1994): Household interview response rate is 86% and the medical examination response rate is 78%.
  • NHANES 1999-2000: Household interview response rate is 82% and the medical examination response rate is 76%.
  • NHANES 2001-2002: Household interview response rate is 84% and the medical examination response rate is 80%.
  • NHANES 2003-2004: Household interview response rate is 79% and the medical examination response rate is 76%.
  • NHANES 2005-2006: Household interview response rate is 80% and the medical examination response rate is 77%.

Primary Survey Content

Chronic disease prevalence and conditions (including undiagnosed conditions), risk factors, dietary intake and nutritional status, immunization status, infectious disease prevalence, health insurance, and measures of environmental exposures. Other topics addressed include hearing, vision, mental health, anemia, diabetes, cardiovascular disease, osteoporosis, obesity, oral health, and physical fitness.

Population Targeted

For NHANES III, the civilian noninstitutionalized population residing in the United States age 2 months and over. Beginning in 1999, people of all ages are included.

Demographic Data

Age, gender, age, education, race/ethnicity, place of birth, income, occupation, industry.

Years Collected

From 1960 to 1994, a total of 7 national examination surveys were conducted. Beginning in 1999, the survey has been conducted continuously. The most recent data release is for the 2005-2006 period.

Schedule

Fielded periodically (1960-1994); continuously beginning in 1999, with data releases occurring in 2-year cycles.

Geographic Estimates

National, four U.S. Census Bureau regions (NHANES III).

National Health Interview Survey (NHIS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Personal interview in households using computer-assisted personal interviewing (CAPI), administered by professional interviewers and conducted in English and Spanish (the CAPI Spanish version was initiated in mid-1998). A new NHIS instrument, which utilizes Blaise® computer-assisted interviewing software, was implemented for the 2004 survey year.

Survey Sample Design

The NHIS is a cross-sectional household interview survey. Sampling and interviewing are continuous throughout each year. The sampling plan follows a multistage area probability design that permits the representative sampling of households. The sampling plan is redesigned after every decennial census. The current sampling plan was implemented in 2006. It has many similarities to the previous sampling plan, which was in place from 1995 to 2005.

The first stage of the current sampling plan consists of a sample of 428 primary sampling units (PSUs) drawn from approximately 1,900 geographically defined PSUs that cover the 50 States and the District of Columbia. A PSU consists of a county, a small group of contiguous counties, or a metropolitan statistical area. Within a PSU, two types of second-stage units are used: area segments and permit segments. Area segments are defined geographically and contain an expected 8, 12, or 16 addresses. Permit segments cover housing units built after the 2000 census. The permit segments are defined using updated lists of building permits issued in the PSU since 2000 and contain an expected four addresses.

The current NHIS sample design continues the oversampling of both Blacks and Hispanics that was a new feature of the previous sample design. A new feature of the current sample design is that Asians are oversampled as well. In addition, the sample adult selection process has been revised so that Blacks, Hispanics, and Asians age 65 and over have an increased probability of being selected. The new sample design is anticipated to result in approximately 87,500 people residing in 35,000 households with completed interviews each year. The survey is designed so that the sample scheduled for each week is representative of the target population and the weekly samples are additive over time.

Primary Survey Content

Information is obtained on demographic characteristics, illnesses, injuries, impairments, chronic conditions, use of health resources, health insurance, and other health topics. The core household interview asks about everyone in the household. Additional questions are asked of one sample adult and one sample child (under 18 years) per family in the household. The sample adult questionnaire includes chronic health conditions, limitations in activity, health behaviors, health care access, health care provider contacts, immunizations, and AIDS knowledge and attitudes. The sample child questionnaire includes questions about chronic health conditions, limitations in activities, health status, behavior problems, health care access and use, and immunizations. Child data are proxy-reported by a parent or other knowledgeable adult respondent. Adult data are all self-reported. Special modules are fielded periodically and cover areas such as cancer, prevention, disability, and use of complementary and alternative medicine.

Population Targeted

Civilian noninstitutionalized population residing in the United States, all ages.

Demographic Data

Age, gender, race/ethnicity, education, income, marital status, place of birth, industry, and occupation.

Years Collected

Continuously since 1957. Current sample design began in 2006; current questionnaire design began in 1997.

Schedule

Annual.

Geographic Estimates

National, four U.S. Census Bureau regions, some of the 10 Health and Human Services regions, some States, metropolitan and nonmetropolitan areas.

Notes

The annual response rate of NHIS is close to 90% of the eligible households in the sample.

Some NHIS and National Vital Statistics System tables report metropolitan statistical areas, based on the 2000 Office of Management and Budget standards for defining metropolitan and micropolitan areas and on the 2000 census, as defined below:

  • Metropolitan categories
    • Large central: Central counties in metro areas of 1 million or more population.
    • Large fringe: Outlying counties in metro areas of 1 million or more population.
    • Medium: Counties in metro areas of 250,000-999,999 population.
    • Small: Counties in metro areas of 50,000-249,999 population.

National Hospital Ambulatory Medical Care Survey (NHAMCS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Hospital staff were asked to complete one-page questionnaires (patient record forms) on a sample of their patient visits during an assigned reporting period.

Survey Sample Design

The NHAMCS is a national probability sample survey of visits to emergency departments (EDs) and outpatient departments (OPDs) of non-Federal, short-stay, and general hospitals in the United States. The NHAMCS uses a four-stage probability design that involves samples of primary sampling units (PSUs), hospitals within PSUs, clinics within hospitals, and patient visits within clinics and/or emergency service areas. Hospital staff are asked to complete Patient Record forms for a systematic random sample of patient visits occurring during a randomly assigned 4-week reporting period during the survey year. Sample data are weighted to produce national estimates of patient visits. About 400 EDs and 225 OPDs participate each year. In 2005, 33,605 ED forms and 29,975 OPD forms were completed.

Primary Survey Content

The NHAMCS includes two files: ED visits and OPD visits. Information is obtained on various aspects of patient visits, including patient, hospital, and visit characteristics. The survey form is redesigned every 2 to 4 years to address changing health data needs. Among the items collected are patient's age, gender, race, and ethnicity; patient's expressed reason for visit; intentionality of injury, if any; physician's diagnoses; diagnostic services ordered or provided; procedures provided; medications; providers seen; visit disposition; immediacy with which patient should be seen; and expected source of payment. Items collected that are specific to the ED include mode of arrival, waiting time, duration of time in the ED, initial vital signs, and cause of injury.

Population Targeted

The basic sampling unit is the patient visit. Included in the survey are in-person visits made to EDs and OPDs of non-Federal, short-stay, and general hospitals, exclusive of Federal, military, and Veterans Affairs hospitals, located in the 50 States and the District of Columbia. Telephone contacts and visits for administrative purposes are excluded. NHAMCS is weighted to give national estimates of ED and hospital OPD visits.

Demographic Data

National Hospital Discharge Survey (NHDS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Manual sample selection and abstraction of inpatient medical records by U.S. Census Bureau field personnel or automated data collection through the purchase of electronic files from commercial sources, States, or hospitals.

Survey Sample Design

The NHDS uses a three-stage national probability design that includes primary sampling units (PSUs) used for the 1985-1994 National Health Interview Survey (NHIS), hospitals within the PSUs, and discharges within the hospitals. Approximately 300,000 discharges are sampled each year from about 500 hospitals.

Primary Survey Content

Variables collected include age; gender; race; ethnicity; admission and discharge dates (length of stay); discharge status; source of payment; hospital size, ownership, and region; from one to seven diagnoses coded using the International Classification of Diseases Ninth Revision, Clinical Modification (ICD-9-CM); and from zero to four procedures using the ICD-9-CM.

Population Targeted

The NHDS contains a sample of discharges from non-Federal, noninstitutional hospitals, located in the 50 States and the District of Columbia. Only hospitals with an average length of stay for all patients of less than 30 days or with a general (medical/surgical) or children's specialty are included in the survey.

NHDS data are weighted to give national and regional estimates of hospital discharges from non-Federal, noninstitutional hospitals.

Demographic Data

Patient's age, gender, race, ethnicity.

Years Collected

1965 to present.

Schedule

Annual.

Geographic Estimates

National, four U.S. Census Bureau regions.

Notes

Data on race are not available from some hospitals because the hospitals provide data from billing forms that do not include race as a required item. In general, nonresponse for race in the NHDS is about 22 to 25%. Nonresponse for Hispanic origin is greater, at about 60 to 63% annually.

National Immunization Survey (NIS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Immunization and Respiratory Diseases (NCIRD), National Center for Health Statistics (NCHS).

Mode of Administration

The NIS is a two-phase survey. The first phase is a list-assisted random-digit-dialing telephone survey of households with children ages 19 to 35 months. The second phase is a mailed survey of vaccination providers identified during the household interviews.

Survey Sample Design

In each of 56 or more State and local geographic areas (which together make up the United States), the NIS draws independent quarterly samples of telephone numbers and then uses random-digit dialing to identify households that have one or more children ages 19 to 35 months. The telephone interview continues by collecting vaccination information for each such child and requesting consent to contact the providers of the child's vaccinations. In a second phase, a mail survey, the NIS asks the providers to report vaccination information from the child's medical record, which is generally more accurate and complete than the household's information.

Primary Survey Content

Vaccination coverage rates for each of 10 recommended vaccines for the Nation and for each of 56 or more selected areas, consisting of the 50 States, the District of Columbia, and 5 large urban areas that receive direct Section 317 immunization grants, and a variable number of other city/county areas designated by State immunization programs.

Population Targeted

Children ages 19 to 35 months living in the United States at the time of the interview.

National Tuberculosis Surveillance System (NTBSS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for HIV, Viral Hepatitis, STD, and TB Prevention (NCHHSTP), Division of Tuberculosis Elimination (DTBE).

Mode of Administration

Currently, individual tuberculosis (TB) case reports (report of verified case of tuberculosis, or RVCT) are submitted electronically via the Tuberculosis Information Management System (TIMS), a comprehensive CDC software system for TB surveillance, patient management, and program evaluation.

Sample Design

Since 1953, through the cooperation of State and local health departments, CDC has collected information on the numbers of reported TB cases in the United States.

In January 1993, DTBE implemented an expanded TB surveillance system, which collects additional information for each reported TB case in order to better monitor trends in TB.

Currently data are collected from 60 reporting areas (the 50 States, the District of Columbia, New York City, Puerto Rico, and other jurisdictions in the Pacific and Caribbean).

Primary Content

Number of new TB cases, patient management, and program evaluation.

The expanded surveillance system started in 1993 collects additional data to better monitor and target groups at risk for TB disease, to estimate and follow the extent of drug-resistant TB, and to evaluate outcomes of TB cases. The RVCT form for reporting TB cases was revised to collect information on occupation, initial drug regimen, HIV test results, history of substance abuse and homelessness, and residence in correctional or long-term care facilities at the time of diagnosis. RVCT Follow Up Report-1 was added to collect drug susceptibility results for the initial M. tuberculosis isolate from patients with culture-positive disease. To evaluate the outcomes of TB therapy, RVCT Follow Up Report-2 was added to collect information on the reason and date therapy was stopped, type of health care provider, sputum culture conversion, use of directly observed therapy, and results of drug susceptibility testing for the final M. tuberculosis isolate from patients with culture-positive disease.

Population Targeted

Civilian population residing in the United States at diagnosis of TB.

Demographic Data

Age, gender, race, country of origin.

Years Collected

Since 1953 (in aggregate form). Since 1985 (in individual case report form).

National Vital Statistics System—Linked Birth and Infant Death Data (NVSS-I)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Linked birth and infant death data are part of the Nation's vital and health statistics. Vital statistics are provided through State-operated registration systems. Administrative records (death certificates) completed by physicians, coroners, medical examiners, and funeral directors, and administrative records (birth certificates) completed by physicians and midwives are filed with State vital statistics offices; selected statistical information is forwarded to NCHS to be merged into a national statistical file.

Sample Design

NVSS mortality files include data for the 50 States, the District of Columbia, and the territories of Puerto Rico, Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Marianas. All deaths (all ages) occurring in those areas are included (approximately 2.3 to 2.4 million annually).

Standard forms for the collection of the data and model procedures for the uniform registration of the events are developed and recommended for State use through cooperative activities of the States and NCHS.

Software is available to automate coding of medical information on the death certificate, following World Health Organization rules specified in the International Classification of Diseases (ICD).

In the linked birth and infant death data set, the information from the death certificate is linked to the information from the birth certificate for each infant less than 1 year old who dies in the United States, Puerto Rico, the Virgin Islands, and Guam.

Primary Content

The linked files include information from death and birth certificates. The vital statistics general mortality data are a fundamental source of geographic and cause-of-death information and some demographic information. The birth certificate is the primary source of demographic information, such as age, race, and Hispanic origin of the parents; maternal education; live birth order; and mother's marital status; and of maternal and infant health information, such as birth weight, period of gestation, plurality, prenatal care usage, and maternal smoking.

Population Targeted

National.

Demographic Data

Age, gender, race, Hispanic origin of the parents.

Years Collected

Linked data are available for the data years 1983 to 1991 and 1995 to 2004.

Schedule

Data are collected/produced annually.

Geographic Estimates

National, by State.

Place of death is classified by State and county. In residence classification, all deaths are allocated to the usual place of residence as reported on the death certificate and are classified by State, county, and city. The public use file identifies counties of 250,000 population or more.

National Vital Statistics System—Mortality (NVSS-M)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Administrative records (death certificates) completed by funeral directors, physicians, medical examiners, and coroners are filed with State vital statistics offices; selected statistical information is forwarded to NCHS to be merged into a national statistical file. Beginning with 1989, revised standard certificates replaced the 1978 versions; implementation of the next revision, for 2003, is being phased in by the States. Demographic information on the death certificate is provided by the funeral director and is based on information supplied by an informant. Medical certification of cause of death is provided by a physician, medical examiner, or coroner.

Sample Design

NVSS mortality files include data for the 50 States, the District of Columbia, and the territories of Puerto Rico, Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Marianas. All deaths occurring in those areas are included (approximately 2.3 to 2.4 million annually).

Primary Content

Year of death, place of decedent's residence, place death occurred, age at death, day of week and month of death, Hispanic origin, race, marital status (beginning in 1979), place of birth, gender, underlying and multiple causes of death for all States, injury at work (beginning in 1993), hospital and patient status, and educational attainment (beginning in 1989) for selected States.

Population Targeted

U.S. population.

Demographic Data

Gender, race, Hispanic origin (beginning in 1984), age at death, place of decedent's residence, educational attainment (beginning in 1989) for selected States, marital status. Race and ethnic origin are separate items on the death certificate. Beginning with 1992 data, California, Hawaii, Illinois, New Jersey, New York, Texas, and Washington reported expanded Asian and Pacific Islander categories of Asian Indian, Korean, Vietnamese, Samoan, and Guamanian. The rest of the States reported a combined Other Asian and Pacific Islander category in addition to the categories of White, Black, American Indian, Chinese, Hawaiian, Japanese, and Filipino that all States report. As of 1997, all States report Hispanic origin. The categories reported include Mexican, Puerto Rican, Cuban, Central and South American, and Other Hispanic. Beginning with data for 2003, multiple-race data will be available for selected States.

Years Collected

The data system began in 1880, but not all States participated before 1933. Coverage for deaths has been complete since 1933.

Schedule

Annual.

Geographic Estimates

National, regional, State, county. Beginning with 1989 data, some changes were initiated to increase confidentiality protection. Identifying information, including date of death and geographic identifiers for counties of less than 100,000 people, is not available for public use.

National Vital Statistics System—Natality (NVSS-N)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Administrative records (birth certificates) completed by physicians and midwives are filed with State vital statistics offices; selected statistical information is forwarded to NCHS to be merged into a national statistical file. Beginning with 1989, revised standard certificates replaced the 1978 versions; implementation of the next scheduled revision, for 2003, is being phased in by the States. Demographic information on the birth certificate is provided by the informant, usually the mother; maternal and infant health information is provided by the physician.

Sample Design

NVSS natality files include data for the 50 States, the District of Columbia, and the territories of Puerto Rico, Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Marianas. All births occurring in those areas are included (approximately 4 million annually).

Primary Content

Demographic items collected include year of birth, place of mother's residence, place birth occurred, age of mother and father, day of week and month of birth, Hispanic origin and race of mother and father, marital status of mother, place of birth (i.e., State or country) of mother and father, educational attainment of mother, sex of child, and live-birth order. Maternal and infant health information is collected, including month prenatal care began, number of prenatal visits, medical risk factors, tobacco use, alcohol use, maternal weight gain, obstetric procedures, attendant at birth, method of delivery, place of delivery, complications of labor and delivery, period of gestation, birth weight, Apgar score, abnormal conditions of newborn, congenital anomalies, and plurality.

Population Targeted

U.S. resident population.

Demographic Data

Gender of child, race of mother and father, Hispanic origin (beginning in 1978) of mother and father, age of mother and father, place of mother's residence, educational attainment of mother and father (beginning in 1978) (education of father not currently collected), and marital status of mother. Race and Hispanic origin are separate items on the birth certificate. Beginning with 1992 data, California, Hawaii, Illinois, New Jersey, New York, Texas, and Washington have reported expanded Asian and Pacific Islander (API) categories of Asian Indian, Korean, Vietnamese, Samoan, and Guamanian. Eleven States currently collect expanded API categories. The rest of the States report a combined Other Asian and Pacific Islander category in addition to the categories of White, Black, American Indian, Chinese, Hawaiian, Japanese, and Filipino that all States report. As of 1993, all States report Hispanic origin. The categories reported include Mexican, Puerto Rican, Cuban, Central and South American, and Other Hispanic. Birth and fertility rates by race and Hispanic origin for the 1990s through 2001 have been revised and published, using populations consistent with the 2000 census.

Years Collected

The national birth registration system was established in 1915. Not all States participated before 1933. Coverage for births has been complete since 1933.

Schedule

Annual.

Geographic Estimates

National, regional, State, county, cities of 100,000 population or more. Beginning with 1989 data, some changes were initiated to increase confidentiality protection. Identifying information, including geographic identifiers for counties of less than 100,000 people, is not available for public use.
