Improving asthma outcomes in minority children: a randomized, controlled trial of parent mentors.

OBJECTIVE: Because asthma disproportionately affects minorities, we evaluated the effects of parent mentors (PMs) on asthma outcomes in minority children. METHODS: This randomized, controlled trial allocated minority asthmatic children to the PM intervention or traditional asthma care. Intervention families were assigned PMs (experienced parents of asthmatic children who received specialized training). PMs met monthly with children and families at community sites, phoned parents monthly, and made home visits. Ten asthma outcomes and costs were monitored for 1 year. Outcomes were examined by using both intention-to-treat analyses and stratified analyses for high participants (attending >or=25% of community meetings and completing >or=50% of PM phone interactions). RESULTS: Patients were randomly assigned to PMs (n = 112) or the control group (n = 108). In intention-to-treat analyses, intervention but not control children experienced significantly reduced rapid-breathing episodes, asthma exacerbations, and emergency department (ED) visits. High participants (but not controls or low participants) experienced significantly reduced wheezing, asthma exacerbations, and ED visits and improved parental efficacy in knowing when breathing problems are controllable at home. Mean reductions in missed parental work days were greater for high participants than controls. The average monthly cost per patient for the PM program was $60.42, and net savings of $46.16 for high participants. CONCLUSIONS: For asthmatic minority children, PMs can reduce wheezing, asthma exacerbations, ED visits, and missed parental work days while improving parental self-efficacy. These outcomes are achieved at a reasonable cost and with net cost savings for high participants. PMs may be a promising, cost-effective means for reducing childhood asthma disparities.

Urban minority children with asthma: substantial morbidity, compromised quality and access to specialists, and the importance of poverty and specialty care.

BACKGROUND: Asthma disproportionately affects minorities, but not enough is known about morbidity and specialist access in asthmatic minority children. OBJECTIVE: To examine asthma morbidity and access to specialty care in urban minority children. METHODS: A consecutive series was recruited in 2004-2007 of urban minority children 2 to 18 years old seen for asthma in four emergency departments (EDs) or admitted to a children's hospital. Outcomes assessed included asthma symptom and attack frequency; missed school and parental work; asthma ED visits and hospitalizations; severity of illness; and asthma specialty care. RESULTS: Of 648 children assessed, 220 were eligible. The mean age was 7 years; 68% were poor, 83% had Medicaid, 84% were African-American, and 16% were Latino. Sixty-eight percent of children were not in excellent/very good health, 73% had persistent asthma (moderate/severe = 52%), and only 44% had asthma care plans. The mean number of asthma attacks in the past year was 12, and of monthly daytime and nighttime asthma symptoms, is 12 and 12, respectively. The mean annual number of asthma doctor visits was 6; of ED asthma visits, 3; hospitalizations, 1; missed school days, 7; and missed parent work days, 6. Eighty-three percent of children have no asthma specialist, and 62% use EDs as the usual asthma care source. Poor children were less likely than the non-poor to have asthma specialists (13 vs. 26%; p < 0.03). African-Americans were more likely than Latinos to use EDs for usual asthma care (68% vs. 44%; p < 0.01). In multivariable analyses, poverty was associated with greater odds and having an asthma care plan with lower odds of an asthma attack in the past year; poverty also was associated with half the odds of having an asthma specialist. African-American children were significantly more likely to report the ED as the usual source of asthma care, and having an asthma specialist and male gender were associated with greater odds of having an asthma care plan. CONCLUSIONS: Urban minority children with asthma average 1 asthma symptom daily, 1 exacerbation monthly, and 7 missed school days, 6 missed parental work days, 3 ED visits, and 1 hospitalization yearly; most receive their usual asthma care in EDs and have no asthma care plan or asthma specialist. Urban minority asthmatic children need interventions to reduce morbidity and improve access to specialists and asthma care plans, especially among the poor and African-Americans.

Reasons for prolonged bottle-feeding and iron deficiency among Mexican-American toddlers: an ethnographic study.

OBJECTIVE: Several studies have shown that prolonged bottle-feeding is associated with iron deficiency. Mexican-American toddlers are the racial/ethnic group at greatest risk for prolonged bottle-feeding and iron deficiency, yet no studies have examined reasons for prolonged bottle-feeding in Mexican-American toddlers. The objective of this study was to assess infant feeding beliefs, knowledge, and behaviors among Mexican-American parents. METHODS: Ethnographic interviews were conducted of parents of Mexican-American toddlers 15 to 48 months old at 3 community sites. A 31-question moderator's guide addressed 4 domains: knowledge and cultural beliefs; sources of nutritional information; anticipatory guidance; and suggestions for ways to change infant feeding practices. Interviews were audiotaped, transcribed, and analyzed using grounded theory. RESULTS: Thirty-nine parents were interviewed; the mean parental age was 29 years, and mean child age, 2.2 years. Parents cited convenience as a reason for prolonged bottle-feeding, and believed that they should give toddlers as much milk as they want. Many parents lacked essential knowledge regarding infant feeding practices and iron deficiency, including when to stop bottle-feeding, health problems caused by prolonged bottle-feeding, the quantity of milk to give a child >1 year old, and iron deficiency as a complication of prolonged bottle-feeding. Parents reported not receiving enough education from physicians, and they supported educational interventions on healthy infant feeding practices, including refrigerator magnet charts, videos, brochures, and teaching by physicians. CONCLUSIONS: Parents of Mexican-American toddlers often are unaware of the adverse consequences of prolonged bottle-feeding and developmental problems associated with iron deficiency. Parents supported educational interventions, including videos, brochures, and refrigerator magnet charts on healthy infant feeding practices.

Why do parents bring children to the emergency department for nonurgent conditions? A qualitative study.

OBJECTIVE: Nonurgent conditions account for 58% to 82% of pediatric emergency department (ED) visits, but only 1 preliminary qualitative study has examined reasons why parents bring children to the ED for nonurgent care. The aim of this study was to identify parents' reasons for choosing the ED over their primary care provider (PCP) for nonurgent pediatric care. METHODS: Audiotaped ethnographic interviews in English and Spanish were conducted of parents of children presenting for nonurgent care on weekdays from 8 AM to 4 PM at a children's hospital ED over a 4-week period. RESULTS: For the 31 families interviewed, the mean parental age was 28 years, and mean child age, 3 years. Reasons cited by caregivers for choosing the ED over their child's PCP were long appointment waits, dissatisfaction with the PCP, communication problems (accents and unhelpful staff at PCP), health care provider referral, efficiency, ED resources, convenience, quality of care, and ED expertise with children. Some parents said they would like education on the urgency of pediatric problems. CONCLUSIONS: Parents bring their children to the ED for nonurgent care because of problems with their PCP, PCP referral, and perceived advantages to ED care. Although parents report that education on the urgency of pediatric conditions would be helpful, substantial reduction of pediatric nonurgent ED use may require improvements in families' PCP office access, efficiency, experiences, and appointment scheduling.

The importance of cultural competency in general pediatrics.

PURPOSE OF REVIEW: There is a growing awareness of the importance of cultural competency in pediatrics. The authors review the most recent studies that examine the impact of cultural competency on general pediatric care, explore cultural beliefs and practices affecting clinical care, and describe culturally sensitive interventions designed to address racial/ethnic health disparities. RECENT FINDINGS: The beneficial effects of cultural competency embrace health outcomes, quality of care, and patient satisfaction, while failure to consider language and culture can have serious adverse consequences for clinical care, including patient safety and healthcare access. A five-component model of cultural competency has been developed, and a growing literature details an array of normative cultural values, folk illnesses, parent beliefs/practices, and provider behaviors that can have a profound impact on pediatric care. Culturally sensitive interventions are being developed to lessen racial/ethnic health disparities. SUMMARY: A goal for the pediatrician is to provide culturally competent healthcare by using trained medical interpreters with limited English-proficient families, being familiar with normative cultural values that affect the healthcare of commonly encountered racial/ethnic groups, and asking about folk illness beliefs and ethnomedical treatments.

Secular trends in the prevalence of iron deficiency among US toddlers, 1976-2002.

OBJECTIVE: To examine secular trends in iron deficiency among US children 1 to 3 years old. DESIGN: Secular trend analyses of the National Health and Nutrition Examination Survey II-IV. SETTING: Large-scale national survey conducted by the National Center for Health Statistics from 1976 to 2002. PARTICIPANTS: US children 1 to 3 years old. Outcome Measure Prevalence of iron deficiency. RESULTS: Between 1976 and 2002, there was no change in iron deficiency prevalence in US toddlers. Iron deficiency prevalence remained unchanged in Hispanic and white toddlers but decreased among black toddlers. Across all 3 survey waves, racial/ethnic disparities in iron deficiency persisted between Hispanic and white toddlers, with a disparity ratio of at least 2. Iron deficiency prevalence remained high (20%-24%) in overweight toddlers, significantly higher than in those at risk for overweight (11%) and in normal weight or underweight toddlers (8%). Iron deficiency prevalence decreased from 22% to 9% in toddlers in poor households but remained unchanged in toddlers in nonpoor households (7%). In multivariable analyses, Hispanic, younger, and overweight toddlers had higher odds of iron deficiency. CONCLUSIONS: Despite the decline in iron deficiency prevalence among 1-year-old, black, and poor children, iron deficiency prevalence in US toddlers overall has not changed in the last 26 years and remains elevated in certain high-risk groups: Hispanic, younger, and overweight toddlers. Efforts to reduce the prevalence of iron deficiency in infancy and early childhood are urgently needed and should target high-risk groups.

Leave no asthmatic child behind: the cultural competency of asthma educational materials.

OBJECTIVE: Cultural competency leads to higher quality care for asthmatic children, yet it is not known whether asthma educational materials targeting minority children and families are culturally competent. The study objective was to evaluate the cultural competency of printed asthma educational materials targeting minorities in Wisconsin. PATIENTS AND METHODS: The Wisconsin Asthma Coalition Disparities Workgroup held a series of meetings to develop, test, and apply a tool for evaluating the cultural competency of asthma educational materials targeting minorities in Wisconsin. The tool consists of seven domains: language, normative cultural values, folk illnesses, parent/patient beliefs, provider practices, visuals, and an overall assessment. Asthma educational materials were obtained from healthcare organizations and clinics. All seven domains were scored using a 5-point Likert scale. RESULTS: Only 17 asthma educational materials targeting minorities exist in Wisconsin: 16 for Latinos, one for Native Americans, none for African Americans, and none for Asians/Pacific Islanders. Overall assessment scores for each material ranged from 1-2 (poor-fair), with a mean+/-SD=1.4+/-0.5. The highest mean domain scores were for language (3.5+/-1.2) and illustrations (3.4+/-1.4); the lowest score was for folk illnesses (1.1+/-0.2), with weaknesses identified for parent/patient beliefs (1.8+/-0.7); provider practices (1.8+/-0.7); and normative cultural values (2.5+/-0.7). CONCLUSIONS: The few asthma educational materials targeting minorities that exist in Wisconsin are not culturally competent. More culturally competent asthma educational materials for minorities are needed.

Iron deficiency in early childhood in the United States: risk factors and racial/ethnic disparities.

BACKGROUND: Iron deficiency affects 2.4 million US children, and childhood iron-deficiency anemia is associated with behavioral and cognitive delays. Given the detrimental long-term effects and high prevalence of iron deficiency, its prevention in early childhood is an important public health issue. OBJECTIVES: The study objectives were to (1) identify risk factors for iron deficiency in US children 1 to 3 years old, using data from the most recent waves of the National Health and Nutrition Examination Survey IV (1999-2002) and (2) examine risk factors for iron deficiency among Hispanic toddlers, the largest minority group of US children. PATIENTS AND METHODS: Analyses of the National Health and Nutrition Examination Survey IV were performed for a nationally representative sample of US children 1 to 3 years old. Iron-status measures were transferrin saturation, free erythrocyte protoporphyrin, and serum ferritin. Bivariate and multivariable analyses were performed to identify factors associated with iron deficiency. RESULTS: Among 1641 toddlers, 42% were Hispanic, 28% were white, and 25% were black. The iron deficiency prevalence was 12% among Hispanics versus 6% in whites and 6% in blacks. Iron deficiency prevalence was 20% among those with overweight, 8% for those at risk for overweight, and 7% for normal-weight toddlers. Fourteen percent of toddlers with parents interviewed in a non-English language had iron deficiency versus 7% of toddlers with parents interviewed in English. Five percent of toddlers in day care and 10% of the toddlers not in day care had iron deficiency. Hispanic toddlers were significantly more likely than white and black toddlers to be overweight (16% vs 5% vs 4%) and not in day care (70% vs 50% vs 43%). In multivariable analyses, overweight toddlers and those not in day care had higher odds of iron deficiency. CONCLUSIONS: Toddlers who are overweight and not in day care are at high risk for iron deficiency. Hispanic toddlers are more likely than white and black toddlers to be overweight and not in day care. The higher prevalence of these risk factors among Hispanic toddlers may account for their increased prevalence of iron deficiency.

Weight control among obese adolescents: a pilot study.

OBJECTIVE: The present study evaluated weight loss and compliance outcomes for overweight adolescents assigned to one of two dietary interventions differing in the type of snacks allowed. METHODS: The study was a 12-week, controlled clinical trial, among otherwise healthy but overweight (body mass index >or=95th percentile) 11-year-old to 15-year-old girls who were randomly assigned to either a 1,500 kcal/day free-snack program or a 1,500 kcal/day restricted-snack program. All subjects were counseled to consume three servings of dairy products per day, and were provided with a 500 mg calcium supplement as well. Subjects in the free-snack group could choose any 150-calorie item as one of their two daily snacks, including regular soda if desired; however, subjects in the restricted-snack group were limited to diet soda. RESULTS: Thirty-two adolescent girls completed the 12-week intervention. Both diets were equally effective in achieving a modest amount of weight loss, and were equally acceptable to the subjects. Significant decreases in weight, body mass index, anthropometric measures, total cholesterol and triglycerides were observed. CONCLUSIONS: A 1,500 kcal/day diet allowing for a free snack of 150 calories was equally as effective as a more restricted snack policy in achieving a modest amount of weight loss among overweight 11-year-old to 15-year-old girls. In addition, results suggest that some soda may be included in a teen weight control diet, as long as caloric intake is maintained at recommended levels, and care is taken to achieve adequate intake of essential nutrients. Calcium intake among subjects was low at baseline, and, although it increased during the study (due to supplementation), further efforts to increase consumption of naturally calcium-rich and calcium-fortified foods and beverages are needed.

Iron deficiency, prolonged bottle-feeding, and racial/ethnic disparities in young children.

BACKGROUND: Childhood iron deficiency is associated with behavioral and cognitive delays. Few studies have explored the relationship between prolonged bottle-feeding and iron-deficiency anemia among toddlers. OBJECTIVE: To examine the association between prolonged bottle-feeding and iron deficiency in a nationally representative sample of children ages 1 to 3 years. DESIGN AND METHODS: The National Health and Nutrition Examination Survey III provides data on the feeding practices of children 1 to 3 years old and contains measures of iron status including transferrin saturation, free erythrocyte protoporphyrin, and serum ferritin. The prevalence of iron deficiency and duration of bottle-feeding were determined for black, white, and Mexican American toddlers. Bivariate and multivariate analyses were performed to examine the association between bottle-feeding duration and iron deficiency. RESULTS: Among 2121 children ages 1 to 3 years, the prevalence of iron deficiency was 6% among whites, 8% among blacks, and 17% among Mexican Americans (P< .001). With increasing duration of bottle-feeding, the prevalence of iron deficiency among all children increased (3.8%, bottle-fed < or =12 months; 11.5%, bottle-fed 13-23 months; and 12.4%, bottle-fed 24-48 months [P< .001]). At 24 to 48 months of age, 36.8% of Mexican American children were still bottle-fed, compared with 16.9% of white and 13.8% of black children. In multivariate analyses, bottle-feeding for 24 to 48 months and Mexican ethnicity were associated with iron deficiency (odds ratio, 2.8; 95% confidence interval, 1.3-6.0; and odds ratio, 2.9; 95% confidence interval, 1.5-5.6, respectively). CONCLUSIONS: Children with prolonged bottle-feeding and Mexican American children are at higher risk for iron deficiency. Screening practices and nutritional counseling should be targeted at these high-risk groups.

Inadequate access to care among children with asthma from Spanish-speaking families.

Despite substantial asthma prevalence and morbidity, children from Spanish-speaking families are at high risk of inadequate maintenance therapy. The reasons for this remain unclear. The objective of this study was to compare patterns of asthma morbidity and access to care of children with asthma from Spanish-speaking and English-speaking families. Cross-sectional data from a nationally representative sample of children with asthma 2-17 years of age were analyzed from the 1999 National Health Interview Survey, conducted in both English and Spanish, with the preferred language identified at the time of the interview. Among the 1,228 children with asthma (physician-diagnosed asthma by parent report), 66 (3%) were from Spanish-speaking families and 1,162 (97%) were from English-speaking families. In a logistic regression model adjusting for gender, insurance, poverty (above or below the federal poverty level, based on reported family income and the U.S. Poverty Threshold produced annually by the Census Bureau), and race/ethnicity, children with asthma from Spanish-speaking families were one-third less likely to have a usual health care provider (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.1-0.8) than children with asthma from English-speaking families. Latino ethnicity was not independently associated with diminished continuity of care. These data indicate that children with asthma from Spanish-speaking families are less likely to experience continuity of health care than their counterparts from English-speaking families. Differences in continuity of care may contribute to inadequate asthma maintenance therapy among these children.

Body size and cardiovascular risk factors in a preschool population.

Data on weight, height, blood pressure, and blood lipids were obtained for 1215 children entering New York Head Start preschools from 1995-1997. In this population, 17% were overweight and 15% were obese; the risk was greatest in Hispanic children. Overall, 13% had high blood pressure. African-American children were at increased risk of elevated blood pressure but had a more favorable lipid profile (high high-density lipoprotein cholesterol level and low triglycerides level) than white or Hispanic children. Body size was a significant predictor of elevated blood pressure, low high-density lipoprotein cholesterol, and increased triglycerides. The association between obesity and blood pressure was evident in white and Hispanic children only. Neither ethnicity nor obesity was associated with total cholesterol level. Obese preschoolers had approximately three times the risk of having high systolic blood pressure and twice the risk of low high-density lipoprotein cholesterol level compared with nonobese children, indicating that at-risk populations can be identified and primary prevention begun at a young age.

Cardiovascular risk reduction in preschool children: the "Healthy Start" project.

OBJECTIVE: To evaluate the impact of a multicomponent cardiovascular health intervention ("Healthy Start") which included a food service modification in a largely minority Head Start preschool population. The primary outcome measure was the change in serum cholesterol from the beginning to the end of the school year. METHODS: Nine Head Start centers in Upstate N.Y. were assigned to either food service modification or control conditions. In addition, half of the centers assigned to the food service modification received supplemental nutrition education (FS/NU--food service modification/nutritional education), while the remaining centers were provided with supplemental safety education materials (FS--food service modification only). The control preschool centers (CON) also received supplemental safety educational curricula for children but their food services remained unchanged. Children had serum cholesterol, as well as height and weight measured at the beginning and end of the school year. A generalized linear univariate procedure was used with percent change in total serum cholesterol as the outcome variable and intervention group as the primary independent variable. RESULTS: There was a significant decrease in total serum cholesterol among preschool children in food service intervention groups, (FS/NU and FS), compared to Controls (-6.0 versus -0.4 mg/dL). In addition to the significant difference in group means, children with elevated cholesterol at baseline were significantly more likely to have a cholesterol level in the normal range (<170 mg/dL) at follow-up if they attended a preschool in the food service modification group. There was a 30% reduction in risk of elevated cholesterol in the latter compared to controls. Participation in the dietary intervention did not affect short-term growth. CONCLUSIONS: A preschool heart health intervention, "Healthy Start," designed to reduce the total and saturated fat content of snacks and meals to recommended levels was effective in reducing serum cholesterol in the study population as a whole and specifically children 'at risk'; i.e., those with initial elevated serum cholesterol.
