Disparities in human papillomavirus vaccination coverage in the United States,National Health and Nutrition Examination Survey,January 2017–March 2020

BackgroundWe assessed disparities in HPV vaccination coverage by sociodemographic characteristics in the United States.MethodsUsing 2017-March 2020 National Health and Nutrition Examination Survey data, we estimated vaccination coverage of ≥ 1 dose of HPV vaccine by race/ethnicity and poverty, insurance, and nativity status for females and males aged 9–14, 15–19, and 20–29 years.ResultsAmong those aged 9–14 years, coverage among non-Hispanic Black (NHB), Hispanic, and non-Hispanic Asian (NHA) females (40.0%, 33.6%, 34.0%) and males (27.1%, 35.3%, 30.9%) was higher than non-Hispanic White (NHW) females (26.5%) and males (25.2%). Among those aged 15–19 and 20–29 years, coverage varied among NHB, Hispanic, and NHA compared to NHW females and was lower among NHB, Hispanic, and NHA than NHW males. Coverage was lower among uninsured than insured in most comparisons.ConclusionsHPV vaccination coverage varied by race/ethnicity and other characteristics. Efforts are needed to increase HPV vaccination coverage in all populations.     

Reasons for the Increasing Hispanic Infant Mortality Rate: Florida, 2004–2007

Assess whether the 55% increase in Florida's Hispanic infant mortality rate (HIMR) during 2004-2007 was real or artifactual. Using linked data from Florida resident live births and infant deaths for 2004-2007, we calculated traditional (infant Hispanic ethnicity from death certificates and maternal Hispanic ethnicity from birth certificates) and nontraditional (infant and maternal Hispanic ethnicity from birth certificate maternal ethnicity) HIMRs. We assessed trends in HIMRs (per 1,000 live births) using Chi-square statistics. We tested agreement in Hispanic ethnicity after implementation of a revised 2005 death certificate by using kappa statistics and used logistic regression to test the associations of infant mortality risk factors. Hispanic was defined as being of Mexican, Puerto Rican, Cuban, Central/South American, or other/unknown Hispanic origin. During 2004-2007 traditional HIMR increased 55%, from 4.0 to 6.2 (Chi-square, P < 0.001) and nontraditional HIMR increased 20%, from 4.5 to 5.4 (Chi-square, P = 0.03). During 2004-2005, agreement in Hispanic ethnicity did not change with use of the revised certificate (kappa = 0.70 in 2004; kappa = 0.76 in 2005). Birth weight was the most significant risk factor for trends in Hispanic infant mortality (OR = 1.33, 95% CI = 1.10-1.61). Differences in Hispanic reporting on revised death certificates likely accounted for the majority of traditional HIMR increase, indicating a primarily artifactual increase. Reasons for the 20% increase in nontraditional HIMR during 2004-2007 should be further explored through other individual and community factors. Use of nontraditional HIMRs, which use a consistent source of Hispanic classification, should be considered.     

Race/ethnicity and self-reported diabetes among adults in the National Health Interview Survey: 2000-2003

OBJECTIVE: We investigated the effect of race among Hispanic and non-Hispanic people on self-reported diabetes after adjusting for selected individual characteristics and known risk factors. METHODS: Using the National Health Interview Survey 2000-2003, these analyses were limited to Hispanic and non-Hispanic people who self-identified as white or black/African American for a final sample of 117,825 adults, including 17,327 Hispanic people (with 356 black and 16,971 white respondents). RESULTS: The overall prevalence of diabetes was 7.2%. After adjusting for selected covariates, Hispanic white and black respondents were 1.56 (95% confidence interval [CI] 1.32, 1.83) and 2.64 (95% CI 1.10, 6.35) times more likely to report having diabetes than non-Hispanic white respondents. The estimate for non-Hispanic black respondents was 1.45 (95% CI 1.29, 1.64). When compared to low-income non-Hispanic white respondents, low-income Hispanic white respondents (odds ratio [OR] 1.64; 95% CI 1.26, 2.19) and non-Hispanic black respondents (OR 1.71; 95% CI 1.38, 2.11) were more likely to report having diabetes. Hispanic black people born in the U.S. were 3.54 (95% CI 1.27, 9.82) times more likely to report having diabetes when compared to Hispanic white people born in the U.S. In comparison to non-Hispanic white respondents, the odds of reporting diabetes decreased for non-Hispanic black respondents, while the odds remained constant for Hispanic white respondents (p-value for interaction between survey year and race/ethnicity = 0.03). CONCLUSIONS: This study suggests that race may be a proxy for unmeasured exposures among non-Hispanic and Hispanic people. Thus, given the importance of race on health and the racial heterogeneity among Hispanic people, race among Hispanic people should be investigated whenever the data allow it.     

Prevalence of health conditions and predictors of mortality in oldest old Mexican Americans and non-Hispanic whites

BackgroundThe oldest old represent a unique group of older adults. This group is rapidly growing worldwide and yet there are gaps in the knowledge related to their health condition. Ethnic differences in disease prevalence and mortality must be understood to better care for the oldest old.ObjectiveTo compare prevalence of common health conditions and predictors of mortality in oldest old Mexican Americans and non-Hispanic whites.MethodsThis study included 568 community-dwelling Mexican Americans (MA) aged 85 years and older from the Hispanic Established Population for the Epidemiological Study of the Elderly 2004–2005 and 933 non-Hispanic whites (NHW) of the same age from the Health and Retirement Study 2004. Measures included sociodemographic variables, self-reported medical conditions, activities of daily living (ADLs), and instrumental activities of daily living. Logistic regression analysis was used to examine 2-year mortality in both populations.ResultsHeart attack was significantly more prevalent in oldest old NHW compared with MA, regardless of gender. Conversely, diabetes was significantly more prevalent among MA men and women compared with their NHW counterparts. Compared with NHW men, MA men had significantly higher prevalence of cognitive impairment and hypertension. Additionally, prevalence of hip fracture was significantly higher for MA women compared with NHW women. Significant differences in ADL disability were observed only between both groups of women, whereas significant differences in instrumental activities of daily living disability were observed only between men. MA men and women had higher prevalence of obesity compared with NHW. Predictors of 2-year mortality for both ethnic groups included older age, male gender, and ADL disability. Cognitive impairment was a mortality predictor only for NHW. Similarly, lung disease was a predictor only for MA.ConclusionHealth-related conditions that affect the oldest old vary by gender and ethnicity and entail careful evaluation and monitoring in the clinical setting. Better care requires inclusion of such differences as part of the comprehensive evaluation of the oldest old adults.     

Hypertension-related mortality among Hispanic subpopulations--United States, 1995-2002

Hypertension remains a major public health problem in the United States even though effective therapy has been available for more than 50 years. Hypertension is a strong independent risk factor for heart disease and stroke and a predictor of premature death and disability from cardiovascular complications. Although age-adjusted prevalence of hypertension is lower among Hispanics than among blacks or non-Hispanic whites, recent data indicate that certain Hispanic subpopulations (Mexican Americans, Puerto Rican Americans, Cuban Americans, and other Hispanic Americans) are characterized by low levels of hypertension awareness, treatment, and control. Because Hispanics are the fastest growing and youngest racial/ethnic population in the United States, targeted strategies to reduce morbidity and mortality rates among this population are essential. Since 1995, information on Hispanic ethnicity has been provided on nearly all death certificates issued in the United States. Although data on Hispanic subpopulations are also available on death certificates, no national mortality statistics on hypertension-related deaths among specific Hispanic subpopulations have been published. To compare age-standardized, hypertension-related death rates among Hispanic subpopulations, CDC analyzed death certificate data from 1995 and 2002. This report describes the results of that analysis, which indicated that Puerto Rican Americans had consistently higher hypertension-related mortality (HRM) rates than all other Hispanic subpopulations and non-Hispanic whites. Comprehensive hypertension prevention and control programs are needed to target these Hispanic subpopulations.     

Disparities in gestational age–specific fetal mortality rates in the United States, 2009–2013

PurposeAlthough studies have examined overall temporal changes in gestational age–specific fetal mortality rates, there is little information on the current status of racial/ethnic differences. We hypothesize that differences exist between racial/ethnic groups across gestational age and that these differences are not equally distributed.MethodsUsing the 2009–2013 data from US fetal death and live birth files for non-Hispanic white (NHW); non-Hispanic black (NHB); Hispanic; and American Indian/Alaska Native (AIAN) women, we conducted analyses to examine fetal mortality rates and estimate adjusted prevalence rate ratios and 95% confidence intervals (CIs).ResultsThere were lower risks of fetal mortality among NHB women (aPRR = 0.76; 95% CI = 0.71–0.81) and Hispanic women (aPRR = 0.89; 95% CI = 0.83–0.96) compared with NHWs at 22–23 weeks’ gestation. For NHB women, the risk was higher starting at 32–33 weeks (aPRR = 1.11; 95% CI = 1.04–1.18) and continued to increase as gestational age increased. Hispanic and AIAN women had lower risks of fetal mortality compared with NHW women until 38–39 weeks.ConclusionsFurther examination is needed to identify causes of fetal death within the later pregnancy period and how those causes and their antecedents might differ by race and ethnicity.     

The Association Between Exposure to Maternal Depression During Year 2 of a Child’s Life and Future Child Problem Behavior

Introduction

We examined the association of exposure to maternal depression during year 2 of a child’s life with future child problem behavior. We conducted a secondary analysis to investigate whether race/ethnicity is a moderator of this relationship.

Methods

We used Fragile Families and Child Well-Being Study data (age 3 N?=?3288 and 49% Black, 26% Hispanic, 22% non-Hispanic White; age 5 N?=?3001 and 51% Black, 25% Hispanic, 21% non-Hispanic White; age 9 N?=?3630 and 50% Black, 25% Hispanic, 21% non-Hispanic White) and ordinal logistic regression to model problem behavior at ages 3, 5, and 9 on maternal depression status during year 2.

Results

At age 9, children whose mother was depressed during year 2 were significantly more likely to have higher internalizing (AOR?=?1.92, 95% CI: 1.42,2.61) and externalizing (AOR?=?1.65, 95% CI: 1.10,2.48) problem behavior scores. In our secondary analysis, race/ethnicity did not have moderating effects, potentially due to a limitation of the data that required use of maternal self-reported race/ethnicity as a proxy for child race/ethnicity.

Discussion

Exposure to maternal depression after the prenatal and perinatal periods may have a negative association with children’s behavioral development through age 9. Interventions that directly target maternal depression during this time should be developed. Additional research is needed to further elucidate the role of race/ethnicity in the relationship between maternal depression and child problem behavior.

     

Validity of demographic characteristics on the death certificate.

In a sample of the United States population from the Census Bureau's current Population Surveys, we compared demographic characteristics with those recorded on the death certificate for the 43,000 decedents in the samples followed from 1979 to 1985. Overall percentage agreements were: Sex 99.5, Race 99.4, Place of birth 99.4, Hispanic origin 98.7, and Veteran status 95.2. Relatively fewer American Indians and Asian/Pacific Islanders had death certificates that agreed with the baseline race (73.6% and 82.4%, respectively). The direction of disagreement suggests that current estimates of mortality rates for American Indians and Asian/Pacific Islanders are underestimated.     

Discrepancies between published data on racial classification and self-reported race: evidence from the 2002 North Carolina live birth records

OBJECTIVES: We compared data on race as reported by the mother on North Carolina birth certificates with data on race in officially reported statistics. We also determined to what extent differences in the classification of race affect measures of racial disparity in maternal and child health indicators. METHODS: We examined how data on race are collected, coded, and tabulated in North Carolina via live birth certificates, death certificates, the Behavioral Risk Factor Surveillance System (BRFSS) telephone survey, and the Central Cancer Registry case records. We showed how the data on race collected through North Carolina birth and death certificates are translated into 10 fixed racial categories designated by the National Center for Health Statistics (NCHS) for use in official vital statistics. We compared race as reported by the mother on birth certificates to racial tabulations used in the official published birth statistics. We also examined to what extent differences in the determination of race affect measures of racial disparity in maternal and child health indicators. RESULTS: Out of nearly 118,000 live births in North Carolina in 2002, mothers reported more than 600 different versions of race on birth certificates. These entries were collapsed into the 10 standard racial categories outlined in federal coding rules. Approximately two-thirds of mothers of Hispanic ethnicity report their race with a label that can be categorized as "Other" race, but nearly all of these births are re-coded to "white" for the official birth statistics. Measures of racial disparity vary depending on whether self-reported or officially coded race is used. CONCLUSIONS: This study shows that, given the opportunity to report their own race, North Carolinians describe their race using a wide variety of terms and concepts. In contrast, health statistics are usually reported using a few standardized racial categories defined by federal policy. The NCHS rules for coding race should be reexamined. As the ethnic and racial diversity of the United States continues to increase, these rules will become increasingly antiquated.     

The validity of information on "race" and "Hispanic ethnicity" in California birth certificate data

OBJECTIVE: To evaluate the validity of racial/ethnic information in California birth certificate data. DATA SOURCES: Computerized birth certificate data and postpartum interviews with California mothers. STUDY DESIGN AND DATA COLLECTION: Birth certificates were matched with face-to-face structured postpartum interviews with 7,428 mothers to compare racial/ethnic information between the two data sources. Interviews were conducted in Spanish or English during delivery stays at 16 California hospitals, 1994-1995. PRINCIPAL FINDINGS: The sensitivity of racial/ethnic classification in birth certificate data was very high (94 percent to 99 percent) for African Americans, Asians/Pacific Islanders, Europeans/Middle Easterners, and Latinas (Hispanics). For Native Americans, however, the sensitivity was only 54 percent. The positive predictive value of birth certificate classification of race/ethnicity was high for all racial/ethnic groups (96 percent to 97 percent). CONCLUSIONS: Despite limited training of birth clerks, the maternal racial/ethnic information in California birth certificate data appears to be a valid measure of self-identified race and Hispanic ethnicity for groups other than Native Americans.     

Out-of-hospital coronary death in an urban population--validation of death certificate diagnosis. The Minnesota Heart Survey

To assess the validity of death certificate diagnoses of out-of-hospital coronary heart disease deaths, the authors studied a one-third random sample of out-of-hospital deaths occurring in 1979 in Minneapolis-St. Paul, Minnesota, residents. Death certificates with diagnoses possibly containing coronary heart disease deaths were enumerated, and cause of death was recorded from the certificate in two ways: as the first listed ("immediate") cause and as the "underlying cause" assigned by a trained nosologist. Validation was performed by standardized physician review of information obtained about the death, which included one or more of the following: an interview with a relative or friend, physician report, autopsy report, medical record, and/or nursing home record. Missing information was frequent, but cases with at least an informant interview and/or autopsy report (82%) were representative and could be used for validation. The sensitivity and specificity of the underlying cause of coronary heart disease (International Classification of Diseases, Ninth Revision, codes 410-414, 427) on the death certificate were 90.3% and 82.7%, respectively, compared with the physician-assigned diagnosis. For the immediate cause, sensitivity and specificity were 90.3% and 67.9%, respectively. These findings suggest that the validity of death certificates for out-of-hospital coronary heart disease death is high, as assessed by this method of retrospective physician review.     

Birth Mode after Primary Cesarean among Hispanic and non-Hispanic Women at One U.S. Institution

BackgroundDespite a lower percentage of primary cesareans than non-Hispanic White and Black women, Hispanic women in the United States had the highest rate of repeat cesarean deliveries (RCD) in 2016; it is unclear if reasons for differences are due to known risk factors. Our study examined the association between ethnicity/race and RCD among women with one previous cesarean and whether demographic (age, marital status, education, language, and delivery year), anthropomorphic (height, prepregnancy body mass index), obstetrical/medical (parity, gestational age, infant birth weight, gestational diabetes, labor induction or augmentation, vaginal birth after cesarean delivery history), or health system (delivery day/time, payer source, provider gender) factors accounted for any observed differences by ethnicity/race.MethodsOur retrospective cohort study used logistic regression to evaluate the relationship between ethnicity/race and RCD based on data from electronic delivery and prenatal records from 2010 to 2016, including 1800 births to Hispanic and non-Hispanic women with one previous cesarean at a District of Columbia hospital.ResultsStatistically significant differences by ethnicity/race were noted after adjustment for obstetric/medical factors, particularly parity and use of induction or augmentation methods. Hispanic (adjusted odds ratio, 2.48; 95% confidence interval, 1.03–6.01) and Black women (adjusted odds ratio, 2.83; 95% confidence interval, 1.67–4.81) had higher odds of RCD than White women.ConclusionsAdjustment for parity and use of induction or augmentation methods revealed higher odds of RCD for Hispanic and Black women than White women. Demographic and anthropometric factors did not alter these results. Our work is a first step in creating effective public health policy and programs that target potentially preventable RCD by highlighting the need to evaluate risk factors beyond those included in the literature to date.     

Comparison of methods for classifying Hispanic ethnicity in a population-based cancer registry.

The accuracy of ethnic classification can substantially affect ethnic-specific cancer statistics. In the Greater Bay Area Cancer Registry, which is part of the Surveillance, Epidemiology, and End Results (SEER) Program and of the statewide California Cancer Registry, Hispanic ethnicity is determined by medical record review and by matching to surname lists. This study compared these classification methods with self-report. Ethnic self-identification was obtained by surveying 1,154 area residents aged 20-89 years who were diagnosed with cancer in 1990 and were reported to the registry as being Hispanic or White non-Hispanic. Predictive value positive, sensitivity, and relative bias were used to assess the accuracy of Hispanic classification by medical record and surname. Among those persons classified as Hispanic by either or both of these sources, only two-thirds agreed (predictive value positive = 66%), and many self-identified Hispanics were classified incorrectly (sensitivity = 68%). Classification based on either medical record or surname alone had a lower sensitivity (59% and 61%, respectively) but a higher predictive value positive (77% and 70%, respectively). Ethnic classification by medical record alone resulted in an underestimate of Hispanic cancer cases and incidence rates. Bias was reduced when medical records and surnames were used together to classify cancer cases as Hispanic.     

COVID-19–Related Hospitalization Rates and Severe Outcomes Among Veterans From 5 Veterans Affairs Medical Centers: Hospital-Based Surveillance Study

BackgroundCOVID-19 has disproportionately affected older adults and certain racial and ethnic groups in the United States. Data quantifying the disease burden, as well as describing clinical outcomes during hospitalization among these groups, are needed.ObjectiveWe aimed to describe interim COVID-19 hospitalization rates and severe clinical outcomes by age group and race and ethnicity among US veterans by using a multisite surveillance network.MethodsWe implemented a multisite COVID-19 surveillance platform in 5 Veterans Affairs Medical Centers located in Atlanta, Bronx, Houston, Palo Alto, and Los Angeles, collectively serving more than 396,000 patients annually. From February 27 to July 17, 2020, we actively identified inpatient cases with COVID-19 by screening admitted patients and reviewing their laboratory test results. We then manually abstracted the patients'' medical charts for demographics, underlying medical conditions, and clinical outcomes. Furthermore, we calculated hospitalization incidence and incidence rate ratios, as well as relative risk for invasive mechanical ventilation, intensive care unit admission, and case fatality rate after adjusting for age, race and ethnicity, and underlying medical conditions.ResultsWe identified 621 laboratory-confirmed, hospitalized COVID-19 cases. The median age of the patients was 70 years, with 65.7% (408/621) aged ≥65 years and 94% (584/621) male. Most COVID-19 diagnoses were among non-Hispanic Black (325/621, 52.3%) veterans, followed by non-Hispanic White (153/621, 24.6%) and Hispanic or Latino (112/621, 18%) veterans. Hospitalization rates were the highest among veterans who were ≥85 years old, Hispanic or Latino, and non-Hispanic Black (430, 317, and 298 per 100,000, respectively). Veterans aged ≥85 years had a 14-fold increased rate of hospitalization compared with those aged 18-29 years (95% CI: 5.7-34.6), whereas Hispanic or Latino and Black veterans had a 4.6- and 4.2-fold increased rate of hospitalization, respectively, compared with non-Hispanic White veterans (95% CI: 3.6-5.9). Overall, 11.6% (72/621) of the patients required invasive mechanical ventilation, 26.6% (165/621) were admitted to the intensive care unit, and 16.9% (105/621) died in the hospital. The adjusted relative risk for invasive mechanical ventilation and admission to the intensive care unit did not differ by age group or race and ethnicity, but veterans aged ≥65 years had a 4.5-fold increased risk of death while hospitalized with COVID-19 compared with those aged <65 years (95% CI: 2.4-8.6).ConclusionsCOVID-19 surveillance at the 5 Veterans Affairs Medical Centers across the United States demonstrated higher hospitalization rates and severe outcomes among older veterans, as well as higher hospitalization rates among Hispanic or Latino and non-Hispanic Black veterans than among non-Hispanic White veterans. These findings highlight the need for targeted prevention and timely treatment for veterans, with special attention to older aged, Hispanic or Latino, and non-Hispanic Black veterans.     

Disparities in Infant Mortality by Race Among Hispanic and Non-Hispanic Infants

Objectives

U.S.-born Hispanic infants have a well-documented health advantage relative to other minority groups. However, little published research has examined racial heterogeneity within the Hispanic population, in relation to health outcomes. The current study aims to explore possible implications of racial identification for the health of U.S. born Hispanic compared to non-Hispanic infants. Methods Data were drawn from 2007 to 2008 NCHS Cohort Linked Live Birth—Infant Death Files, restricted to deliveries of Hispanic black, Hispanic white, non-Hispanic black (NHB) and non-Hispanic white mothers (NHW) (n?=?7,901,858). Adjusted odds ratios for first week mortality, neonatal, postneonatal, and overall infant mortality were calculated for each group, using NHW as the reference group. Results: A distinct health gradient was observed in which NHB infants (n?=?1,250,222) had the highest risk of first week (aOR?2.29, CI 2.21–2.37), neonatal (aOR 2.23, CI 2.17–2.30), postneonatal (aOR 1.74, CI 1.68–1.81), and infant mortality (aOR 2.05, CI 2.00–2.10) compared to NHW infants (n?=?4,578,150). Hispanic black infants (n?=?84,377) also experienced higher risk of first-week (aOR?1.28 (1.12–1.47), neonatal (aOR .27, CI 1.13–1.44), postneonatal (aOR?1.34, CI 1.15–1.56), and infant mortality (aOR 1.30, CI 1.18–1.43) compared to both NHW and Hispanic white infants (n?=?1,989,109). Conclusions for Practice: Risk of infant mortality varies among Hispanic infants by race, with poorer outcomes experienced by Hispanic black infants. Compared to non-Hispanic infants of the same race, Hispanic black infants experience a smaller health disadvantage and Hispanic white infants have better or similar infant health outcomes. Our findings suggest implications of racial heterogeneity on infant health outcomes, and provide insight into the role of race as a social construct.

     

Cardiovascular disease mortality in Hispanics and non-Hispanic whites

Despite a worse cardiovascular disease (CVD) risk profile, Hispanics have lower CVD mortality than non-Hispanic Whites in studies based on death certificates. This study examined 310 deaths that occurred between 1984 and 1998 among 1,862 Hispanic and non-Hispanic White participants in the San Luis Valley Diabetes Study, using medical records to classify cause of death. Among persons without diabetes, the age-adjusted all-cause mortality rate was 6.1/1,000 person-years in non-Hispanic Whites and 7.4/1,000 person-years in Hispanics. Among persons with diabetes, it was 24.3/1,000 person-years in non-Hispanic Whites and 21.9/1,000 person-years in Hispanics. Among nondiabetics, the age-adjusted CVD mortality rate was 2.5/1,000 person-years in non-Hispanic Whites and 1.6/1,000 person-years in Hispanics. Among diabetics, it was 12.9/1,000 person-years in non-Hispanic Whites and 8.8/1,000 person-years in Hispanics. Among nondiabetics, the adjusted hazard ratio for CVD death in Hispanics compared with non-Hispanic Whites was 0.65 (95% confidence interval (CI): 0.34, 1.23). The hazard ratio for coronary heart disease death was 0.95 (95% CI: 0.35, 2.59). Among diabetics, the hazard ratio for CVD death, after adjustment for conventional and diabetes risk factors, was 0.44 (95% CI: 0.26, 0.74), and for coronary heart disease death it was 0.43 (95% CI: 0.21, 0.91). A statistically significant decreased risk of CVD death was observed only in male Hispanics with diabetes. Competing mortality or factors that interact with diabetes may explain these differences.     

Behavioral health in multiracial adolescents: the role of Hispanic/Latino ethnicity

OBJECTIVES: The purpose of the present study was twofold: (1) to determine whether adolescents who self-identify as multiracial have more adverse health behaviors than their monoracial counterparts, and (2) to examine whether the health behaviors of adolescents who are multiracial and Hispanic are more similar to those who identify as monoracial Hispanic or those who are multiracial and non-Hispanic. METHODS: Secondary analyses of data in a subsample from the Youth Risk Behavior Survey of 3,704 (27.2%) adolescents who identified as Hispanic/Latino only, multiracial Hispanic, or multiracial non-Hispanic were conducted. Regression analyses were conducted using SUDAAN for the complex sampling to test for differences in health behaviors (i.e., smoking, exercise, substance abuse, and suicide risk) among the three ethnicity/race groups. RESULTS: Each health behavior scale yielded significant between-group differences according to ethnic/racial identity: Hispanic/Latino adolescents scored significantly lower than both multiracial groups on the measure of cigarette smoking, lower than multiracial Hispanic adolescents on the substance abuse scale, and lower than multiracial non-Hispanic adolescents on the measure of exercise. The multiracial Hispanic group was also at marginally increased risk for suicide compared to the Hispanic/Latino group. CONCLUSIONS: The results support the hypothesis that multiracial Hispanic adolescents have more behavioral health problems than monoracial Hispanic adolescents. The second hypothesis--that multiracial Hispanic adolescents are more similar to multiracial non-Hispanic adolescents--was also supported. The implications of these findings for the classification of Hispanic adolescents in terms of ethnicity and race in relation to health behaviors are discussed.     

Race/ethnicity misclassification of persons reported with AIDS

Objectives. To examine differences in race/ethnicity classifications of persons with AIDS among three reporting sources and to estimate the effect of these differences on calculated AIDS rates.

Methods. We reviewed case reports from the national AIDS surveillance database, interview (self‐reported) data from 11 state/local health departments, and death certificate information from 16 state/local health departments for agreement in race/ethnicity coding among persons reported with AIDS.

Results. Race/ethnicity coding inconsistencies with AIDS case reports were greatest for persons identified as American Indians/Alaska natives on death certificates (46% [47/102] disagreement) and by self‐report (57% 8/14 disagreement). Agreement with AIDS case reports was highest either for persons identified as white from death certificates (4% [1314/31 070] disagreement) and white from self‐reports (2% [26/1068] disagreement) or black from death certificates (3% [440/13 592] disagreement) and black from self‐reports (3% [21/736] disagreement). For other racial/ethnic groups, disagreement with AIDS case reports was intermediate; for Asians/Pacific Islanders, 12% [45/377] disagreement with death certificates and 33% 4/12 disagreement with self‐reports; and for Hispanics, 14% [1151/8527] disagreement with death certificates and 24% [59/249] disagreement with self‐reports:

Conclusion. For certain racial/ethnic groups, classification by race/ethnicity can differ substantially by surveillance data source. Because allocation of public health resources may be determined by estimates of disease impact on different population groups, periodic evaluations of the accuracy of race and ethnicity reporting are needed to assure appropriate distribution of these resources.     

Maternal Pre-Pregnancy Weight and Gestational Weight Gain and Their Association with Birthweight with a Focus on Racial Differences

Our objectives were to examine the interaction between maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) and their association with birthweight, with a focus on racial differences. We used birth certificate data from live singleton births of South Carolina resident mothers, who self-reported their race as non-Hispanic white (NHW, n = 140, 128) or non-Hispanic black (NHB, n = 82,492) and who delivered at 34–44 weeks of gestation between 2004 and 2008 to conduct a cross-sectional study. Linear regression was used to examine the relationship between our exposures (i.e., race, BMI and GWG) and our outcome birthweight. Based on 2009 Institute of Medicine guidelines, the prevalence of adequate, inadequate and excessive GWG was 27.1, 24.2 and 48.7%, respectively, in NHW women and 24.2, 34.8 and 41.0%, respectively, in NHB women. Adjusting for infant sex, gestational age, maternal age, tobacco use, education, prenatal care, and Medicaid, the difference in birthweight between excessive and adequate GWG at a maternal BMI of 30 kg/m² was 118 g (95% CI: 109, 127) in NHW women and 101 g (95% CI: 91, 111) in NHB women. Moreover, excessive versus adequate GWG conveyed similar protection from having a small for gestational age infant in NHW [OR = 0.64 (95% CI 0.61, 0.67)] and NHB women [OR = 0.68 (95% CI: 0.65, 0.72)]. In conclusion, we report a strong association between excessive GWG and higher infant birthweight across maternal BMI classes in NHW and NHB women. Given the high prevalence of excessive GWG even a small increase in birthweight may have considerable implications at the population level.
