Racial and Ethnic Disparities in Emergency Department Wait Times for Children: Analysis of a Nationally Representative Sample

ObjectiveTo evaluate the association of race and ethnicity with wait times for children in US emergency departments (ED).MethodsWe performed a cross-sectional study of ED encounters of children (<18 years) from 2014 to 2019 using a multistage survey of nonfederal US ED encounters. Our primary variable of interest was composite race and ethnicity: non-Hispanic White (NHW), non-Hispanic Black, Hispanic, and all others. Our outcome was ED wait time in minutes. We evaluated the association between race and ethnicity and wait time in Weibull regression models that sequentially added variables of acuity, demographics, hospital factors, and region/urbanicity.ResultsWe included 163,768,956 survey-weighted encounters. In univariable analysis, Hispanic children had a lower hazard ratio (HR) of progressing to evaluation (HR 0.84, 95% confidence interval [CI] 0.76–0.93) relative to NHW children, indicating longer ED wait times. This association persisted in serial multivariable models incorporating acuity, demographics, and hospital factors. This association was not observed when incorporating variables of hospital region and urbanicity (HR 0.91, 95% CI 0.83–1.00). In subgroup analysis, Hispanic ethnicity was associated with longer wait times in pediatric EDs (HR 0.76, 95% CI 0.63–0.92), non-metropolitan EDs (HR 0.75, 95% CI 0.64–0.89), and the Midwest region (HR 0.77, 95% CI 0.69–0.87). No differences in wait times were observed for children of Black race or other races.ConclusionsHispanic children experienced longer ED wait times across serial multivariable models, with significant differences limited to pediatric, metropolitan, and Midwest EDs. These results highlight the presence of disparities in access to prompt emergency care for children.     

Disparities in Maternal-Infant Drug Testing,Social Work Assessment,and Custody at 5 Hospitals

ObjectiveTo evaluate for disparities in peripartum toxicology testing among maternal-infant dyads across a hospital network and subsequent child protective services (CPS) involvement.MethodsRetrospective chart review of 59,425 deliveries at 5 hospitals in Massachusetts between 2016 and 2020. We evaluated associations between maternal characteristics, toxicology testing, and child welfare involvement with disproportionality risk ratios and hierarchical logistical regression.ResultsToxicology testing was performed on 1959 (3.3%) dyads. Younger individuals and individuals of color were more likely to be tested for cannabis use or maternal medical complications compared to white non-Hispanic individuals. Among those without a substance use disorder, age <25 (adjusted odds ratio [aOR] 2.81; 95% confidence interval [CI], 2.43–3.26), race and ethnicity (non-Hispanic Black (aOR 1.80; 95% CI, 1.52–2.13), Hispanic (aOR 1.23; 95% CI, 1.05–1.45), mixed race/other (aOR 1.40; 95% CI, 1.04, 1.87), unavailable race (aOR 1.92; 95% CI, 1.32–2.79), and public insurance (Medicaid [aOR 2.61; 95% CI, 2.27–3.00], Medicare [aOR 13.76; 95% CI, 9.99–18.91]) had increased odds of toxicology testing compared to older, white non-Hispanic, and privately insured individuals. The disproportionality ratios in testing were greater than 1.0 for individuals under 25 years old (3.8), Hispanic individuals (1.6), non-Hispanic Black individuals (1.8), individuals of other race (1.2), unavailable race (1.8), and individuals with public insurance (Medicaid 2.6; Medicare 10.6). Among dyads tested, race and ethnicity was not associated with CPS involvement.ConclusionsPeripartum toxicology testing is disproportionately performed on non-white, younger, and poorer individuals and their infants, with cannabis use and medical complications prompting testing more often for patients of color than for white non-Hispanic individuals.     

Cranial computed tomography use among children with minor blunt head trauma: association with race/ethnicity

OBJECTIVE To determine if patient race/ethnicity is independently associated with cranial computed tomography (CT) use among children with minor blunt head trauma. DESIGN Secondary analysis of a prospective cohort study. SETTING Pediatric research network of 25 North American emergency departments. PATIENTS In total, 42?412 children younger than 18 years were seen within 24 hours of minor blunt head trauma. Of these, 39?717 were of documented white non-Hispanic, black non-Hispanic, or Hispanic race/ethnicity. Using a previously validated clinical prediction rule, we classified each child's risk for clinically important traumatic brain injury to describe injury severity. Because no meaningful differences in cranial CT rates were observed between children of black non-Hispanic race/ethnicity vs Hispanic race/ethnicity, we combined these 2 groups. MAIN OUTCOME MEASURE Cranial CT use in the emergency department, stratified by race/ethnicity. RESULTS In total, 13?793 children (34.7%) underwent cranial CT. The odds of undergoing cranial CT among children with minor blunt head trauma who were at higher risk for clinically important traumatic brain injury did not differ by race/ethnicity. In adjusted analyses, children of black non-Hispanic or Hispanic race/ethnicity had lower odds of undergoing cranial CT among those who were at intermediate risk (odds ratio, 0.86; 95% CI, 0.78-0.96) or lowest risk (odds ratio, 0.72; 95% CI, 0.65-0.80) for clinically important traumatic brain injury. Regardless of risk for clinically important traumatic brain injury, parental anxiety and request was commonly cited by physicians as an important influence for ordering cranial CT in children of white non-Hispanic race/ethnicity. CONCLUSIONS Disparities may arise from the overuse of cranial CT among patients of nonminority races/ethnicities. Further studies should focus on explaining how medically irrelevant factors, such as patient race/ethnicity, can affect physician decision making, resulting in exposure of children to unnecessary health care risks.     

Interpreting the continued decline in the average age at menarche: results from two nationally representative surveys of U.S. girls studied 10 years apart

OBJECTIVES: To determine whether average age at menarche declined in the United States during the past decade, and whether associations between menarcheal timing, weight status, and race/ethnicity changed. STUDY DESIGN: Relative weight, race/ethnicity, and menarcheal status of girls (n = 1577) in the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) were compared with those of girls (n = 1720) in NHANES 1999-2002. Probit analysis estimated average age at menarche overall and also by race/ethnicity. Logistic regression assessed associations of relative weight and race/ethnicity with menarcheal status. RESULTS: In the United States, average age at menarche declined from 12.53 years (95% confidence interval [CI] = 12.43 to 12.63 years) in 1988-1994 to 12.34 years (95% CI = 12.24 to 12.45 years) in 1999-2002. By race/ethnicity, average age at menarche estimates were as follows: non-Hispanic whites, 12.57 years (95% CI = 12.45 to 12.69 years) and 12.52 years (95% CI = 12.38 to 12.67 years); non-Hispanic blacks, 12.09 years (95% CI = 11.82 to 12.36 years) and 12.06 years (95% CI = 11.81 to 12.32 years); and Mexican Americans, 12.24 years (95% CI = 11.88 to 12.59 years) and 12.09 years (95% CI = 11.81 to 12.37 years). Higher relative weight was consistently associated with increased likelihood of having reached menarche. CONCLUSIONS: Average age at menarche in the United States declined by 2.3 months between 1988-1994 and 1999-2002; by race/ethnicity, declines were considerably smaller. Changes in the population distribution of race/ethnicity and relative weight should be considered when interpreting trends in age at menarche.     

Incidence of childhood type I and non-type 1 diabetes mellitus in a diverse population: the Chicago Childhood Diabetes Registry, 1994 to 2003

BACKGROUND: Reports of increasing risk for type 1 (T1) and type 2 diabetes mellitus in youth are emerging, but information on socioeconomically diverse populations is limited. METHOD: The Chicago Childhood Diabetes Registry is a city-wide study of patients 0-17 years old at onset. Incidence data came from medical records and interviews; census data provided denominators; analyses used Poisson regression. Non-type 1 (nT1) patients had a type 2-like clinical course or related indicators. RESULTS: There were 1,366 incident cases: 719 in non-Hispanic Black (NHB), 379 in Hispanic, 229 in non-Hispanic White (NHW), and 39 in children of other ethnicities. Average annual incidence was 16.0 (95% CI: 14.6, 17.6)/10(5) for boys, 20.1 (18.3, 22.1)/10(5) for girls, and 18.1 (16.9, 19.3)/10(5) overall. Risk was 21.6 (19.6, 23.8)/10(5) for NHB, 14.6 (13.0, 16.4)/10(5) for Hispanic, and 18.1 (15.9, 20.6)/10(5) for NHW. Children aged 10-14 years experienced the highest incidence, irrespective of ethnicity. T1 was predominant in all ethnic groups, except NHB, where the rates of T1 and nT1 were similar. Over ten years there was a marked increase in all childhood diabetes in Chicago, averaging 2.73% (95% CI: 0.49, 5.02) per annum, adjusted for age. This increase was confined to nT1, with an average annual percent change of +6.23% (2.28, 10.34), while T1 incidence remained stable. CONCLUSIONS: Incidence of childhood diabetes increased between 1994-2003, driven primarily by nT1, suggesting a role for behavioral and/or environmental determinants of insulin resistance. These estimates are likely to be conservative, if nT1 cases were more apt to be missed.     

Motor vehicle crash fatalities by race/ethnicity in Arizona, 1990-96.

OBJECTIVE: To compare rates of motor vehicle crash (MVC) fatalities among different race/ethnic groups in urban and rural Arizona. METHOD: Using the Fatality Analysis Reporting System and the National Center for Health Statistics Multiple Cause of Death file, MVC fatalities in Arizona from 1990-96 inclusive were classified by gender, race/ethnicity, and urban or rural residence. Age adjusted rates of total, occupant, pedestrian, and alcohol related fatalities were calculated. The total MVC fatality rate for each race/ethnic group was then adjusted for proportion of rural residence. RESULTS: Compared with non-Hispanic whites (NHWs), American Indians had raised relative risks for MVC fatality in all gender and residence subgroups. Hispanic females and rural Hispanic males had lower relative risks, as did rural African-American men. Raised relative risks for American Indian men and women included all subgroups: total, occupant, pedestrian, and alcohol related. Hispanic and African-American men both had raised relative risks of pedestrian related fatalities, and Hispanic men had a slightly higher relative risk while Hispanic women had a lower relative risks, for alcohol related fatality. Hispanic men and women and African-American men had lower occupant fatality rates. Close to half (45%) of the excess MVC fatality among American Indians can be attributed to residence in rural areas, where MVC fatality rates are higher. There were 1.85 occupants in crashes involving NHW deaths compared with 2.51 for Hispanics and 2.71 for American Indians (p<0.001). The proportion of occupants not using a seatbelt was higher in Hispanics and American Indians in both urban and rural areas. CONCLUSION: The major disparity in MVC fatality in Arizona is among American Indians. The higher MVC fatality rates among American Indians occur in all age groups, in both urban and rural areas, and among occupants and pedestrians. Rural residence, lower rates of seatbelt use, higher rates of alcohol related crashes, a greater number of occupants, and higher rates of pedestrian deaths all contribute to the American Indian MVC fatality disparity. High rates of pedestrian fatality occur in men in all three race/ethnic minorities in Arizona and among American Indian women. In contrast to other studies, African-Americans and Hispanics did not have raised total MVC fatality rates and compared to NHWs actually had lower rates in the rural areas of the state.     

Evaluating the Role of Birth Weight and Gestational Age on Acute Lymphoblastic Leukemia Risk Among Those of Hispanic Ethnicity

High birth weight is an established risk factor for childhood acute lymphoblastic leukemia (ALL), especially in children younger than 5 years of age at diagnosis. The goal of this study was to explore the association between being born large for gestational age and the risk for ALL by race/ethnicity to determine if the role of this risk factor differed by these characteristics. The authors compared birth certificate data of 575 children diagnosed with ALL who were younger than 5 years and included in the Texas Cancer Registry, Texas Department of Health, between the years 1995 and 2003 with 11,379 controls matched by birth year. Stratified odds ratios were calculated for risk of ALL by birth weight for gestational age, categorized in 3 groups, small, appropriate, and large for gestational age (SGA, AGA, and LGA, respectively), for each race/ethnicity group. The risk of developing ALL was higher among Hispanics who were LGA (odds ratio [OR] = 1.90, 95% confidence interval [CI]: 1.34–2.68) compared with LGA non-Hispanic whites (OR = 1.27, 95% CI: 0.87–1.86) after adjusting for infant gender, year of birth, maternal age, birth order, and presence of Down syndrome. However, the difference was not statistically significant. These results suggest that there may be differences in the association between higher growth in utero and risk of childhood ALL among Hispanics versus non-Hispanic whites.     

Risk of preterm birth in multiparous teenagers

BACKGROUND: Previous studies of teenage primiparas have found little or no association between young maternal age and preterm birth. However, the risk of preterm birth in teenage multiparas should not be overlooked because of the high rate of repeat teenage pregnancies. OBJECTIVE: To compare the risk of preterm birth in teenage and adult multiparas. DESIGN: Cross-sectional analysis of US Natality Files, 1990 to 1996. METHODS: We calculated the risk of very preterm birth (<33 weeks' gestation) for multiparas aged 10 to 20 years compared with 25-year-olds, stratified by age and race/ethnicity. Adjusted odds ratios (AORs) were estimated controlling for maternal education, marital status, prenatal care, and previous preterm births. Effects of smoking and interpregnancy interval were analyzed separately. RESULTS: Throughout adolescence, multiparas face higher AORs for very preterm births. For white non-Hispanic multiparas compared with 25-year-old multiparas, 10- to 14-year-olds had an AOR of 4.22 (95% confidence interval [CI], 2.26-7.88), 15- to 17-year-olds had an AOR of 2.19 (95% CI, 1.99-2.42), 18- and 19-year-olds had an AOR of 1.69 (95% CI, 1.58-1.80), and 20-year-olds had an AOR of 1.33 (95% CI, 1.24-1.41). A similar pattern of decreasing AOR with increasing maternal age was observed for black non-Hispanic and Hispanic mothers, although wide race/ethnicity disparities exist. Adjusting for maternal smoking and short interpregnancy interval did not change these results. CONCLUSIONS: Risk of very preterm birth in teenage multiparas is associated with young age after controlling for other risk factors. Interventions to prevent repeat pregnancies and the associated risk of premature birth deserve high priority.     

Hospitalization for respiratory syncytial virus among California infants: disparities related to race, insurance, and geography

OBJECTIVES: To evaluate population-based rates of Respiratory Syncytial Virus (RSV)-associated infant hospitalizations related to race/ethnicity, payer source, and geography in California. STUDY DESIGN: Retrospective analysis of RSV-coded infant hospitalizations were performed using the California patient discharge data for 1999 to 2003. All discharge records for infants younger than 1 year of age with an ICD-9-CM code for any RSV-related illness (466.11, 480.1, or 079.6) among any of the diagnosis fields were selected for analysis (n = 45,330). Rates were expressed as the number of RSV-associated hospitalizations per 1000 live births in the same calendar year. RESULTS: Infants enrolled in MediCal (California's version of the United States' national Medicaid program) had a relative risk of 2.03 (95% CI, 1.99 to 2.06) compared with non-MediCal payers (24.3 vs 12.0/1000 live births, respectively). The 1999 to 2003 rates per 1000 live births of RSV-associated hospitalizations for MediCal payers by race/ethnicity were: non-Hispanic white (34.9), African-American (27.9), Hispanic (21.8), Asian/Pacific Islander (12.5), and American Indian/Alaska Native (12.2). CONCLUSIONS: RSV was the leading cause of infant hospitalizations in California between 1999 and 2003. RSV hospitalization rates were highest among non-Hispanic white MediCal insured infants.     

Exclusive Breastfeeding in the Northwest: Disparities Related to Race/Ethnicity and Substance Use

Background and ObjectivesMothers who are Black, Indigenous, and people of color (BIPOC) are disproportionately impacted by substance use in pregnancy and less likely to breastfeed. Our objectives were to assess relationships between substance use in pregnancy and exclusive breastfeeding at discharge (EBF) and race/ethnicity and EBF, and determine the extent to which substance use influences the relationship between race/ethnicity and EBF.MethodsThis is a retrospective cohort study of term mother-infant dyads using 2016 to 2019 data from a Northwest quality improvement collaborative, Obstetrical Care Outcomes Assessment Program. Stepwise and stratified multivariable logistic regression analyses were conducted to determine associations between independent variables consisting of characteristics, including maternal race/ethnicity and substance use, and the dependent variable, EBF.ResultsOur sample consisted of 84,742 dyads, 69.5% of whom had EBF. The adjusted odds of EBF for non-Hispanic Black and Hispanic mothers were half, and for American Indian/Alaska Native mothers two-thirds, that of White mothers (aOR [95% CI]: 0.52 [0.48, 0.57], 0.51 [0.48, 0.54], 0.64 [0.55, 0.76], respectively). Substance use did not mediate the association between race/ethnicity and EBF, but it modified the association. Among those reporting nicotine or marijuana use, Hispanic mothers were half as likely as White mothers were to exclusively breastfeed. Other factors associated with a lower likelihood of EBF included public or no insurance, rural setting, C-section, NICU admission, and LBW.ConclusionsDisparities in EBF related to race/ethnicity and substance use were pronounced in this study, particularly among Hispanic mothers with nicotine or marijuana use.     

Cancer occurrence in Southeast Asian children in California

OBJECTIVES: To estimate misclassification of ethnicity and cancer incidence in Southeast Asian children using the population-based California Cancer Registry. METHODS: Asian race/ethnicity was evaluated using lists of Asian surnames. Average annual incidence rates (per million) for 1988 to 1992 were calculated for non-Hispanic white, black, Hispanic, and Asian children (age <15 years). Proportional incidence ratios (PIRs) for 1988 to 1995 were used to compare Southeast Asian children to non-Hispanic white children. RESULTS: Of the Asian children, 4.2% (30/722) were misclassified by subgroup, predominantly Hmong listed as Laotian. The Asian cancer rate was 134.2 versus 159.2 for non-Hispanic whites. The germ cell tumor rate was higher in Asians (9.9) than in non-Hispanic whites (4.8), but the Wilms tumor rate was two-thirds lower (3.1 vs. 9.2). The rates of Hodgkin lymphoma and central nervous system tumors were lower (2.8 vs. 5.6 and 20.0 vs. 33.8) in Asians than non-Hispanic whites. Compared with non-Hispanic whites, the PIR for Wilms tumor in Southeast Asian children was reduced (PIR = 0.1). Southeast Asian children had increased PIRs for Burkitt lymphoma (PIR = 2.6) and leukemias not classified as acute lymphocytic leukemia or acute nonlymphocytic leukemia (PIR = 3.5). CONCLUSIONS: Accurate race/ethnicity classification of Southeast Asian children is a concern. Marked differences were found in the incidence and PIRs of specific cancers among Southeast Asian children, other Asian children, and other children in California.     

The Association Between Racial Discrimination,Race, and Social Class With Health Among US Children

ObjectivesTo assess the association between racial discrimination, race and ethnicity, and social class with child health and unmet health care needs among children in the United States (US).MethodsWe used a nationally representative sample of children aged 0 to 17 from the 2018–2019 National Survey of Children's Health. Bivariate and multivariable logistic regression were used to test associations between measures of discrimination, social class (income, employment, and education), and race and ethnicity with overall child health and unmet health care needs controlling for covariates identified a priori.ResultsOverall, 90.3% of children (n = 59,964) had excellent/very good overall health; 3.1% had unmet health care needs. Black, non-Hispanic children had 8.9 times the odds of having experienced racial discrimination compared to White, non-Hispanic children (95% confidence interval [CI], 7.0–11.4). Having special health care needs was significantly associated with greater odds of racial discrimination (OR 2.3; 95% CI, 1.9–2.8). In multivariable models, underrepresented race and ethnicity groups, lower household income level, and lower caregiver education were significantly associated with poorer overall child health. Conversely, experiencing discrimination was not significantly associated with excellent/good overall child health (adjusted odds ratios [aORs], 0.8; 95% CI, 0.6–1.1) Racial discrimination (aOR 2.7; 95% CI, 1.9–4.0) and lower household income (aOR 2.6; 95% CI, 1.8–3.5) were associated with significantly greater odds of unmet health care needs.ConclusionRace and ethnicity and low social class were significantly associated with worse overall health while racial discrimination and low-income were associated with more unmet health care needs. These findings underscore the importance of policy and health care system innovations that address the effects of racism and poverty on child health.     

What Can Providers Learn From Childhood Body Mass Index Trajectories: A Study of a Large,Safety-Net Clinical Population

ObjectiveTo describe childhood weight gain using body mass index (BMI) z-score trajectories in a low-income urban safety-net population and identify among gender- and race/ethnicity-specific groups any trends for increased risk.MethodsA retrospective cohort study was conducted among 2- to 12-year-old patients (2006–2013) visiting a safety-net provider. BMI z-score trajectories were calculated overall, for gender- and race/ethnicity-specific groups, and for peak BMI percentile subgroups to describe weight gain longitudinally.ResultsFrom 2006 to 2013, a total of 26,234 eligible children were followed for an average of 3.7 years. At baseline (mean age, 4.2 years), 74% of patients were at a normal weight compared to 65% at most recent observation (mean age, 7.8 years). All gender and race/ethnicity subgroups showed increasing average BMI z-scores during childhood. Children consistently under the 50th percentile and those of white race had the most stable BMI z-score trajectories. BMI z-score increased with increasing age in all subgroups. Hispanic boys and black girls had the most significant increase in BMI z-score during this observation period. Children observed in early childhood and whose BMI exceeded the 95th percentile at any time were often already overweight (20%) or obese (36%) by 3 years of age.ConclusionsThe entire population demonstrated an upward trend in BMI z-score trajectory. This trend was most notable among black girls and Hispanic boys. Many obese children were already overweight by age 3, and persistence of obesity after 3 years of age was high, suggesting that intervention before age 3 may be essential to curbing unhealthy weight trajectories.     

Meeting breastfeeding intentions differ by race/ethnicity,Infant and Toddler Feeding Practices Study‐2

Prenatal breastfeeding intentions impact breastfeeding practices. Racial/ethnic disparities exist in breastfeeding rates; it is unknown if prenatal intentions and meeting intentions differ by race/ethnicity. A longitudinal cohort of USDA''s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) which enrolled participants beginning in 2013 were used to estimate prenatal intentions for breastfeeding initiation, exclusive breast milk feeds at 1 and 3 months by race/ethnicity (n = 2070). Meeting intentions were determined by reported breast milk consumption at birth, 1 month and 3 months. Multivariable logistic regression was used to determine the association of race/ethnicity with meeting intentions. There were no differences in prenatal breastfeeding intentions between non‐Hispanic White and non‐Hispanic Black women (initiation: 86.9% and 87.2%; Month 1: 52.3% and 48.3%; Month 3: 43.8% and 40.9%; respectively), but a higher percentage of Hispanic women intended to breastfeed at all time points (95.5%, 68.3% and 56.4%; respectively, P < 0.05). Among women who intended to breastfeed at Month 1, non‐Hispanic Black and Hispanic women had significantly lower odds of meeting intentions compared with non‐Hispanic White women after adjusting for covariates (aORs: 0.63 [95% CI: 0.41, 0.98]; 0.64 [95% CI: 0.44, 0.92], respectively). Similar findings were seen for Month 3. Despite no differences in breastfeeding intentions, non‐Hispanic Black women were less likely to meet their breastfeeding intentions than non‐Hispanic White women. Hispanic women were more likely to intend to breastfeed yet were less likely to meet their intentions. This suggests that non‐Hispanic Black and Hispanic women face challenges to meeting their longer breastfeeding intentions. Understanding how racism, bias and discrimination contribute to women not meeting their breastfeeding intentions may help efforts to reduce breastfeeding disparities.     

Decreased prevalence of nonalcoholic fatty liver disease in black obese children

OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) is a common cause of pediatric liver disease. Studies suggest decreased prevalence in blacks, females, and younger children. However, the proportion of black subjects in these studies was small, and children under 12 were not included. We propose that abnormal alanine aminotransferase (ALT) is more common in whites than blacks, males than females, and children over 12 compared with younger children in a prospective study. METHODS: We enrolled 181 consecutive asymptomatic obese children attending general pediatric clinics who denied recent fever or known liver disease. Obesity was defined as body mass index (BMI) z score of greater than 1.64 (95th percentile for age and sex). Elevated ALT was defined as greater than 40 U/L. BMI z score, race, sex, age, and parental obesity were compared using the chi-square test and Fisher's exact test. RESULTS: The population included 81 males and 100 females, 147 non-Hispanic black, 33 non-Hispanic white, and 1 Hispanic white. Elevated ALT occurred in 14 (8%) subjects. White children were significantly more likely to have abnormal ALT (odds ratio [OR] = 4.0, P < .02). Very obese children (BMI z score >2.3) were more likely to have abnormal ALT compared with mildly obese children (OR = 4.0, P < 0.05). Sex, age, hepatomegaly, acanthosis nigricans, and parental obesity did not significantly predict elevated ALT. CONCLUSION: Eight percent of asymptomatic, obese children had an elevated ALT suggestive of NAFLD. White and very obese children are more likely to be affected. Sex and age are not good clinical predictors of NAFLD. We suggest that all obese children be screened for NAFLD.     

Dietary and Physical Activity Behaviors of New York City Children From Different Ethnic Minority Subgroups

ObjectiveTo examine racial/ethnic differences in diet and physical activity behaviors in ethnic minority New York City children.MethodsCross-sectional data from a community-based study of 486 6- to 8-year-old children were used. Race/ethnicity was derived using a caregiver's report of child's race and Hispanic ancestry. Dietary intake was obtained by 24-hour diet recalls using the Nutrition Data System for Research. Physical activity was assessed with pedometers and caregiver interviews. We compared diet and activity measures across racial/ethnic subgroups using chi-square and analysis of variance tests. Multivariate analyses adjusted for age, gender, body mass index, and caregiver education (with breastfeeding history and total energy intake included in diet models).ResultsParticipants (N = 486) were categorized as Mexican (29.4%), Dominican (8.4%), Puerto Rican (20.6%), other/mixed Hispanic (14.0%), or non-Hispanic black (27.6%). Obesity rates were lower in non-Hispanic blacks (18%) than in Hispanics (31%). Mexicans had the lowest obesity rates among Hispanic subgroups (25%), and Dominicans had the highest (39%). There were differences in mean daily servings of food groups, with Mexicans having healthier diets and Puerto Ricans and non-Hispanic Blacks having less healthy diets. Sedentary time was lower in Mexicans than in other groups in adjusted models. Examination of additional models, including home language, did not show significant differences in the estimates.ConclusionDiet and activity behaviors varied across racial/ethnic subgroups. Specifically, Mexican children had healthier diets, the least amount of sedentary time, and the lowest rates of obesity among the Hispanic subgroups examined. Targeted interventions in ethnic subgroups may be warranted to address specific behaviors.     

Mortality after pediatric kidney transplantation in England – a population‐based cohort study

The aim of this study was to explore mortality after pediatric kidney transplantation in England over the last decade. We used data from HES to select all kidney transplant procedures performed in England between April 2001 and March 2012. Data linkage analysis was performed with the ONS to identify all deaths occurring among this study cohort. Data for 1189 pediatric recipients were compared to 17 914 adult recipients (number of deaths, 33 vs. 2052, respectively, p < 0.001), with median follow‐up 4.4 yr (interquartile range 2.2–7.3 yr). There was no difference in mortality within the pediatric cohort; age 0–1 (n = 25, patient survival 100.0%), age 2–5 (n = 198, patient survival 96.0%), age 6–12 (n = 359, patient survival 97.5%), and age 13–18 (n = 607, patient survival 97.4%), respectively (p = 0.567). The most common causes of death were renal (n = 8, 24.2%), infection (n = 6, 18.2%), and malignancy (n = 5, 15.2%). All deaths from malignancy were secondary to PTLD. In a fully adjusted Cox regression model, only white ethnicity was significantly associated with risk of pediatric mortality post‐kidney transplantation (hazard ratio 2.7, 95% confidence interval [1.0–7.3], p = 0.047). To conclude, this population‐based cohort study confirms low mortality after pediatric kidney transplantation with short follow‐up.     

Seat belt use among Hispanic ethnic subgroups of national origin.

OBJECTIVE: Findings from over a dozen studies of Hispanic/white disparities in seat belt use have been inconsistent, variably revealing that seat belt use prevalence among Hispanics is higher, lower, or comparable to use among non-Hispanics. In contrast to previous studies, this study investigates disparities in seat belt use by Hispanic subgroups of national origin. METHODS: Data from the US Fatality Analysis Reporting System were used to compare seat belt use among 60 758 non-Hispanic whites and 6879 Hispanics (Mexican American (MA), n = 5175; Central American/South American (CASA), n = 876; Puerto Rican (PR), n = 412; Cuban (CU), n = 416) killed in crashes from 1999-2003. Logistic regression was used to adjust for age, gender, seat belt law, seat position, urban/rural region, and income. RESULTS: Overall adjusted odds ratios for seat belt use among Hispanic subgroups, relative to non-Hispanic whites, were 1.04 (95% confidence interval (CI) 0.85 to 1.28) for CUs, 1.17 (95% CI 0.95 to 1.44) for PRs, 1.33 (95% CI 1.25 to 1.42) for MAs, and 1.66 (95% CI 1.44 to 1.91) for CASAs. Relative to their non-Hispanic white counterparts, odds ratios among MA and CASA Hispanics were highest for men, younger age groups, drivers, primary law states, rural areas, and lower income quartiles. CONCLUSION: Among all Hispanic subgroups, seat belt use was at least as prevalent as among non-Hispanic whites. In the CASA and MA subgroups, which have the most rapidly growing subpopulations of immigrants, seat belt use was significantly more common than among whites.     

Obesity prevalence in low-income preschool children in oklahoma

Objective. To determine the prevalence of overweight and obesity in low-income preschool children in Oklahoma and to identify potential race/ethnic disparities. Methods. Subjects included 39 151 children aged 2 to 4 years who participated in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in 2009. Body mass index percentiles were calculated from the child's height, weight, sex, and age. Results. In 2009, 30.7% of Oklahoma's children in WIC were overweight, including 13.7% obese. Disparities by race/ethnicity were greatest for obese children: prevalence was 18.8% for American Indians (odds ratio [OR] = 1.8, confidence interval [CI] = 1.54-2.03) and 17.2% for Hispanics (OR = 1.6, CI = 1.52-1.73) compared with 11.8% for non-Hispanic whites, whereas African Americans were less obese (OR = 0.9, CI = 0.79-0.98). Conclusion. Obesity rates in low-income Oklahoma children are highest among American Indians and Hispanic children. Interventions aimed at these high-risk groups need to be explored.
