A Revised ICD-10-CM Surveillance Case Definition for Injury-related Emergency Department Visits.

Background-Administrative data from medical claims are often used for injury surveillance. Effective October 1, 2015, hospitals covered by the Health Insurance Portability and Accountability Act were required to use the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) to report medical information in administrative data. In 2017, the National Center for Health Statistics (NCHS) and the National Center for Injury Prevention and Control (NCIPC) published a proposed ICD-10-CM surveillance case definition for injuryrelated emergency department (ED) visits. At the time, ICD-10-CM coded data were not available for testing. When data became available, NCHS and NCIPC collaborated with the Council of State and Territorial Epidemiologists and epidemiologists from state and local health departments to test and update the proposed definition. This report summarizes the results and presents the 2021 revised ICD-10-CM surveillance case definition.

Heavy Drinking Among U.S. Adults, 2018.

Heavy drinking is defined as the average consumption of more than 7 drinks per week for women and more than 14 drinks per week for men in the past year (1). Heavy drinking is associated with an increased risk of alcohol use disorders, suicide, interpersonal violence, traffic injuries, liver disease, certain cancers and infectious diseases, and adverse birth outcomes in pregnant women (1,2). This report describes adult alcohol use in the United States and presents the prevalence of heavy drinking by demographic characteristics, select mental health indicators, and select measures of health care access and utilization.

Antidepressant Use Among Adults: United States, 2015-2018.

In 2018, an estimated 7.2% of American adults had a major depressive episode in the past year (1). Depression is associated with diminished quality of life and increased disability (2). Antidepressants are one of the primary treatments for depression (3) and are among the most frequently used therapeutic medications in the United States (4). This data brief provides recent prevalent estimates for antidepressant use among U.S. adults aged 18 and over, by age, sex, race and Hispanic origin, and education. Trends in antidepressant use over the decade from 2009-2010 through 2017-2018 are described.

Race/ethnicity, maternal educational attainment, and infant mortality in the United States.

This study examines patterns of and explanations for racial/ethnic-education disparities in infant mortality in the United States. Using linked birth and death data (2007-2010), we find that while education-specific infant mortality rates are similar for Mexican Americans and Whites, infants of college-educated African American women experience 3.1 more deaths per 1,000 live births (Rate Ratio = 1.46) than infants of White women with a high school degree or less. The high mortality rates among infants born to African American women of all educational attainment levels are fully accounted for by shorter gestational lengths. Supplementary analyses of data from the National Longitudinal Study of Adolescent to Adult Health show that college-educated African American women exhibit similar socioeconomic, contextual, psychosocial, and health disadvantages as White women with a high school degree or less. Together, these results demonstrate African American-White infant mortality and socioeconomic, health, and contextual disparities within education levels, suggesting the role of life course socioeconomic disadvantage and stress processes in the poorer infant health outcomes of African Americans relative to Whites.

Disparities in Sarcoidosis Mortality by Region, Urbanization, and Race in the United States: A Multiple Cause of Death Analysis.

PURPOSE: Sex, race/ethnicity, and geographic disparities in sarcoidosis-associated mortality were assessed for the most recent period. METHODS: US data for multiple causes of death for 1999-2016 were used to determine numbers of deaths and age-adjusted rates for sarcoidosis as an underlying or a contributing cause of death using International Classification of Diseases, 10th Revision code D86 for Hispanics, non-Hispanic blacks, and non-Hispanic whites. RESULTS: For persons of all ages in the United States in 1999-2016, there were a total of 28,923 sarcoidosis-associated deaths. In 2008-2016, 9112 deaths had sarcoidosis as the underlying cause (56%) compared with 16,129 with sarcoidosis listed as any cause. Age-adjusted annual death rates per 100,000 were 5.7 (95% confidence interval [CI], 5.6-5.8) for females and 4.1 (95% CI, 4.0-4.2) for males. Age-adjusted annual death rates were 1.5 (95% CI, 1.4-1.6) for Hispanics and 5.4 (95% CI, 5.3-5.4) for non-Hispanics. Rates in non-Hispanic blacks were 8 times those in non-Hispanic whites. Among females, the highest rate was in non-Hispanic blacks in the East-Central division. Between 1999-2007 and 2008-2016, rates increased most in non-Hispanic white males (52.5%) and least in non-Hispanic black females (5.8%). CONCLUSIONS: Sarcoidosis-related multiple cause of death mortality rates were highest in females and in non-Hispanic blacks, and they varied geographically.

Response to Economic Shock: The Impact of Recession on Rural-Urban Suicides in the United States.

OBJECTIVE: This study examines the effect of economic recession on the suicide differential between rural and urban counties. METHODS: A negative binomial regression model and county mortality data are used to estimate the effect of recession and rurality on county-level suicides from 2002-2016. RESULTS: After accounting for differences in population, urban counties have more female suicides than rural counties, but urban counties experience smaller increases in female suicide numbers during periods of recession than rural counties. Long-term factors such as high chronic poverty or unemployment have a greater impact on male suicide rates, while short-term economic crises have a larger impact on female suicides. Higher percentages of children in the county have an increasing effect on male suicides, but a decreasing effect on female suicides. Finally, farm-dependent counties have fewer suicides than non-farm-dependent counties. This holds true for both males and females. CONCLUSIONS: Periods of recession impact suicide numbers; however, this effect is most noticeable for females, with rural counties having larger increases in female suicide numbers than their urban counterparts during recession years.

National Health and Nutrition Examination Survey: California and Los Angeles County, Estimation Methods and Analytic Considerations, 1999-2006 and 2007-2014.

Background California is the most populated state and Los Angeles County is the most populated county in the United States. National Health and Nutrition Examination Survey (NHANES) sample weights and variance units were developed for these places to obtain subnational estimates. Objective This report describes the California and Los Angeles County NHANES 1999-2006 and 2007-2014 samples, including the creation of the sample weights and variance units and descriptions of the resulting data files. Some analytic guidelines are provided. Results Eight years of NHANES data were combined for each data file to provide an adequate sample size and reduce disclosure risks. Because Los Angeles County has been a self-representing primary sampling unit, sample weights for Los Angeles County were relatively straightforward. However, a modelbased approach was used to create sample weights for California. The relatively large proportion of Mexican- American and other Hispanic persons in California, coupled with the different NHANES 1999-2014 sample design requirements for oversampling these groups within the small number of NHANES locations selected each cycle, led to a relatively large size of these groups in the California and Los Angeles County NHANES files. For example, 1,137 and 374 of the 3,353 Mexican-Americans persons in NHANES 2007-2014 were in the California and Los Angeles County samples, respectively. Conclusion The California and Los Angeles County NHANES 1999-2006 and 2007-2014 samples are available in the National Center for Health Statistics Research Data Center.

Data Quality Assessment of the 2014 Native Hawaiian and Pacific Islander National Health Interview Survey.

The 2014 Native Hawaiian and Pacific Islander National Health Interview Survey (NHPI NHIS) is the first federal survey designed exclusively to measure the health of the noninstitutionalized civilian NHPI population of the United States.

Long-Term Trends in Black and White Mortality in the Rural United States: Evidence of a Race-Specific Rural Mortality Penalty.

PURPOSE: The rural mortality penalty-growing disparities in rural-urban macro-level mortality rates-has persisted in the United States since the mid 1980s. Substantial intrarural differences exist: rural places of modest population size, close to urban areas, experience a greater mortality burden than the most rural locales. This research builds on recent findings by examining whether a race-specific rural mortality penalty exists; that is, are some rural areas more detrimental to black and/or white mortality than others? METHODS: Using data from the Compressed Mortality File from 1968 to 2012, we calculate annual age-adjusted, race-specific mortality rates for all rural-urban regions designated by the Rural-Urban Continuum Codes. Indicators for population, socioeconomic status, and health infrastructure, as a proxy for access to care, are used as predictors of race-specific mortality in multivariable regression models. FINDINGS: Three important results emerge from this analysis: (1) there is a substantial mortality disadvantage for both black and white rural Americans, (2) the most advantageous regions of mortality for blacks exhibit higher mortality than the most disadvantageous regions for whites, and (3) access to health care is a much stronger predictor of white mortality than black mortality. CONCLUSIONS: The rural mortality penalty is evident in race-specific mortality trends over time, with an added disadvantage in black mortality. The rate of mortality improvement for rural blacks and whites lags behind their same-race, urban counterparts, creating a diverging gap in race-specific mortality trends in rural America.

[Correlation of size and age in Colombian indigenous children based on WHO and NCHS references]. / Concordancia en la talla para la edad entre referencias NCHS y OMS en indígenas colombianos.

Objective To evaluate the correlation of size, according to age, of the anthropometric growth references of Colombian indigenous children studied in Encuesta Nacional de la Situación Nutricional de Colombia 2010 -ENSIN 2010 (National Survey of Nutrition in Colombia - 2010). Method A secondary analysis of 2598 data of indigenous Colombian children under five years of age, evaluated by ENSIN in 2010, was performed. The considered variables were size according to age, gender, height, place of residence, department and socioeconomic position. The classification of the deficit in size, based on the references of the National Center for Health Statistics (NCHS) and the World Health Organization (WHO), was made by using the Z <-2 score and the Anthro software. The Kappa coefficient was estimated to assess the correlation between anthropometric categories and was classified taking into account the proposal of Altman DG. Results One in four children had a deficit in size in the light of both anthropometric references. The prevalence of the deficit was higher when using the WHO standard, increased with age and was higher in children who resided in low altitude (m). The correlation between the two references was good (kappa ≥0,688, p=0,000) for children of both genders and all ages; the exception corresponded to children of age two, since it was moderate (kappa=0,601, p=0,000). The greatest disagreement in the classification was observed in the category "tall". Conclusion According to the statistical correlation found between the two anthropometric references (WHO vs. NCHS), any reference could be used for assessment of size according to for age.

Linkage of NCHS Population Health Surveys to Administrative Records From Social Security Administration and Centers for Medicare Medicaid Services.

Federally sponsored health surveys are a critical source of information on public health in the United States. The National Center for Health Statistics (NCHS) is the nation's principal health statistics agency and is responsible for collecting accurate, relevant, and timely data. NCHS conducts several population-based national surveys as well as collecting vital statistics data, which are used by a broad range of users (researchers and policy makers, among others) to evaluate and profile the health of the American people. These national health surveys provide rich cross-sectional information on risk factors such as smoking, height and weight, health status, and socioeconomic circumstances, but information on longitudinal outcomes is often missing. Demand is increasing to incorporate information from additional sources in order to enhance the availability and quality of information on exposures and outcomes.

Design and operation of the National Survey of Children with Special Health Care Needs, 2009-2010.

OBJECTIVES: This report presents the development, plan, and operation of the 2009-2010 National Survey of Children with Special Health Care Needs, a module of the State and Local Area Integrated Telephone Survey. The survey is conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. This survey was designed to produce national and state-specific prevalence estimates of children with special health care needs (CSHCN), to describe the types of services that they need and use, and to assess aspects of the system of care for CSHCN. METHODS: A random-digit-dial sample of households with children under age 18 years was constructed for each of the 50 states and the District of Columbia. The sampling frame consisted of landline phone numbers and cellular(cell) phone numbers of households that reported a cell-phone-only or cell-phone-mainly status. Children in identified households were screened for special health care needs. If CSHCN were identified in the household, a detailed interview was conducted for one randomly selected child with special health care needs. Respondents were parents or guardians who knew about the children's health and health care. RESULTS: A total of 196,159 household screening interviews were completed from July 2009 through March 2011, resulting in 40,242 completed special-needs interviews, including 2,991 from cell-phone interviews. The weighted overall response rate was 43.7% for the landline sample, 15.2% for the cell-phone sample, and 25.5% overall.

Summary health statistics for U.S. adults: national health interview survey, 2012.

OBJECTIVES: This report presents detailed tables from the 2012 National Health Interview Survey (NHIS) for the civilian noninstitutionalized adult population, classified by sex, age, race and Hispanic origin, education, current employment status, family income, poverty status, health insurance coverage, marital status, and place and region of residence. Estimates (frequencies and percentages) are presented for selected chronic conditions and mental health characteristics, functional limitations, health status, health behaviors, health care access and utilization, and human immunodeficiency virus testing. Percentages and percent distributions are presented in both age-adjusted and unadjusted versions. DATA SOURCE: NHIS is a household, multistage probability sample survey conducted annually by interviewers of the U.S. Census Bureau for the Centers for Disease Control and Prevention's National Center for Health Statistics. In 2012, data were collected on 34,525 adults in the Sample Adult questionnaire. The conditional response rate was 79.7%, and the final response rate was 61.2%. The health information for adults in this report was obtained from one randomly selected adult per family. HIGHLIGHTS: In 2012, 61% of adults aged 18 and over had excellent or very good health. Eleven percent of adults had been told by a doctor or other health professional that they had heart disease, 24% had been told on two or more visits that they had hypertension, 9% had been told that they had diabetes, and 21% had been told that they had some for of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia. Eighteen percent of adults were current smokers and 21% were former smokers. Based on estimates of body mass index, 35% of adults were overweight and 28% were obese.

2013 NCHS Urban-Rural Classification Scheme for Counties.

OBJECTIVES: This report details development of the 2013 National Center for Health Statistics' (NCHS) Urban-Rural Classification Scheme for Counties (update of the 2006 NCHS scheme) and applies it to health measures to demonstrate urban-rural health differences. METHODS: The methodology used to construct the 2013 NCHS scheme was the same as that used for the 2006 NCHS scheme, but 2010 census-based data were used rather than 2000 census-based data. All U.S. counties and county-equivalent entities are assigned to one of six levels (four metropolitan and two nonmetropolitan) based on: 1) their February 2013 Office of Management and Budget designation as metropolitan, micropolitan, or noncore; 2) for metropolitan counties, the population size of the metropolitan statistical area (MSA) to which they belong; and 3) for counties in MSAs of 1 million or more, the location of principal city populations within the MSA. The 2013 and 2006 NCHS schemes were applied to data from the National Vital Statistics System (NVSS) and National Health Interview Survey (NHIS) to illustrate differences in selected health measures by urbanization level and to assess the magnitude of differences between estimates from the two schemes. RESULTS AND CONCLUSIONS: County urban-rural assignments under the 2013 NCHS scheme are very similar to those under the 2006 NCHS scheme. Application of the updated scheme to NVSS and NHIS data demonstrated the continued usefulness of the six categories for assessing and monitoring health differences among communities across the full urbanization spectrum. Residents of large central and large fringe metro counties differed substantially on many health measures, illustrating the importance of continuing to separate these counties. Residents of large fringe metro counties generally fared better than residents of less urban counties. Estimates obtained from the 2013 and 2006 schemes were similar.

Reconsidering racial/ethnic differences in sterilization in the United States.

OBJECTIVE: Cross-sectional studies have found that low-income and racial/ethnic minority women are more likely to use female sterilization and less likely to rely on a partner's vasectomy than women with higher incomes and whites. However, studies of pregnant and postpartum women report that racial/ethnic minorities, particularly low-income minority women, face greater barriers in obtaining a sterilization than do whites and those with higher incomes. In this paper, we address this apparent contradiction by examining the likelihood a woman gets a sterilization following each delivery, which removes from the comparison any difference in the number of births she has experienced. STUDY DESIGN: Using the 2006-2010 National Survey of Family Growth, we fit multivariable-adjusted logistic and Cox regression models to estimate odds ratios and hazard ratios for getting a postpartum or interval sterilization, respectively, according to race/ethnicity and insurance status. RESULTS: Women's chances of obtaining a sterilization varied by both race/ethnicity and insurance. Among women with Medicaid, whites were more likely to use female sterilization than African Americans and Latinas. Privately insured whites were more likely to rely on vasectomy than African Americans and Latinas, but among women with Medicaid-paid deliveries reliance on vasectomy was low for all racial/ethnic groups. CONCLUSIONS: Low-income racial/ethnic minority women are less likely to undergo sterilization following delivery compared to low-income whites and privately insured women of similar parities. This could result from unique barriers to obtaining permanent contraception and could expose women to the risk of future unintended pregnancies. IMPLICATIONS: Low-income minorities are less likely to undergo sterilization than low-income whites and privately insured minorities, which may result from barriers to obtaining permanent contraception, and exposes women to unintended pregnancies.

Trends in insurance coverage and source of private coverage among young adults aged 19-25: United States, 2008-2012.

KEY FINDINGS: Data from the National Health Interview Survey, 2008-2012. The percentage of young adults with private health insurance coverage increased from the last 6 months of 2010 through the last 6 months of 2012 (52.0% to 57.9%). Except for an increase in the first 6 months of 2011, the percentage of privately insured young adults who had a gap in coverage during the past 12 months decreased from the first 6 months of 2008 through the last 6 months of 2012 (10.5% to 7.8%). The percentage of privately insured young adults with coverage in their own name decreased from 40.8% in the last 6 months of 2010 to 27.2% in the last 6 months of 2012. The percentage of privately insured young adults with employer-sponsored health insurance increased from the last 6 months of 2010 to the last 6 months of 2012 (85.6% to 92.5%). Young adults often experience instability with regard to work, school, residential status, and financial independence. This could contribute to a lack of or gaps in insurance coverage (1,2). In September 2010, the Affordable Care Act (ACA) extended dependent health coverage to young adults up to age 26. This provision was expected to lead to increases in private coverage for young adults aged 19-25 when they became eligible for coverage through their parents' employment (3,4). This report provides estimates describing the previous insurance status and sources of coverage among privately insured young adults aged 19-25, using data from the 2008-2012 National Health Interview Survey (NHIS). Comparisons are made with adults aged 26-34, the most similar age group that was not affected by the ACA provision.

Language and immigrant status effects on disparities in Hispanic children's health status and access to health care.

The objective of this study is to estimate Hispanic/non-Hispanic (nH)-white health disparities and assess the extent to which disparities can be explained by immigrant status and household primary language. The 2007 National Survey of Children's Health was funded by the Maternal and Child Health Bureau, and conducted by Centers for Disease Control and Prevention's National Center for Health Statistics as a module of the State and Local Area Integrated Telephone Survey. We calculated disparities for various health indicators between Hispanic and nH-white children, and used logistic regression to adjust them for socio-economic and demographic characteristics, primary language spoken in the household, and the child's immigrant status. Controlling for language and immigrant status greatly reduces health disparities, although it does not completely eliminate all disparities showing poorer outcomes for Hispanic children. English-speaking and nonimmigrant Hispanic children are more similar to nH-white children than are Hispanic children in non-English speaking households or immigrant children. Hispanic/nH-white health disparities among children are largely driven by that portion of the Hispanic population that is either newly-arrived to this country or does not speak primarily English in the household.

Use of family planning and related medical services among women aged 15-44 in the United States: National Survey of Family Growth, 2006-2010.

OBJECTIVE: This report presents national estimates of the use of family planning services and related medical services among women aged 15-44 in the United States in 2006-2010. Selected indicators are compared with similar measures for 2002 and 1995 to examine changes over time. METHODS: Data for this report come primarily from the 2006-2010 National Survey of Family Growth (NSFG), which included 12,279 interviews with women aged 15-44. The response rate for women in the 2006-2010 NSFG was 78%. RESULTS: In 2006-2010, 43 million women aged 15-44 received a family planning or related medical service in the previous 12 months. A Pap test and a pelvic exam were the most common services received by women in the previous year, followed by receipt of a method of birth control. About 18% of women received a family planning or related medical service from a clinic in the past 12 months and one-half of these women received it from a Title X-funded clinic. In contrast, 53% of women received a family planning or related medical service in the past 12 months from a private doctor. Use of Title X-funded clinics was more common among women in cohabiting unions, black and Hispanic women, those who lived in nonmetropolitan areas, those below the poverty level, and those without health insurance.

Nonresponse in the National Survey of Children's Health, 2007.

OBJECTIVES: For random-digit-dial telephone surveys, the increasing difficulty in contacting eligible households and obtaining their cooperation raises concerns about the potential for nonresponse bias. This report presents an analysis of nonresponse bias in the 2007 National Survey of Children's Health, a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. METHODS: An attempt was made to measure bias in six key survey estimates using four different approaches: comparison of response rates for subgroups, use of sampling frame data, study of variation within the existing survey, and comparison of survey estimates with similar estimates from another source. RESULTS: Even when nonresponse-adjusted survey weights were used, the interviewed population was more likely to live in areas associated with higher levels of home ownership, lower home values, and greater proportions of non-Hispanic white persons when compared with the nonresponding population. Bias was found (although none greater than 3%) in national estimates of the proportion of children in excellent or very good health, those with consistent health insurance coverage, and those with a medical home. However, the level and direction of the bias depended on the approach used to measure it. There was no evidence of significant bias in the proportion of children with preventive medical care visits, those with families who ate daily meals together, or those living in safe neighborhoods.
