Why screen newborns for cocaine: service patterns and social outcomes at age one year.

OBJECTIVE: To compare baseline characteristics, service provision, and child placement for infants exposed to cocaine in utero based on postnatal screening results. METHODS: We studied a retrospective cohort of 40 consecutive drug-exposed, but seemingly healthy term infants who underwent urine drug screening in the newborn nursery of a community hospital. Using clinical and service agency data, two cocaine-exposed cohorts were compared (a) screen-positive at birth (n = 22) versus (b) screen-negative at birth (n = 18). RESULTS: Both cocaine-exposed groups had similar infant birth weights, levels of paternal involvement, maternal ages, gravidity, parity, and lengths of gestation. Mothers in both groups had similar histories of prostitution, poor home environment, drug use, and prenatal drug rehabilitation. Mothers of screen-positive infants were more likely than mothers of screen-negative infants to have other children in foster care (27% vs. 6%, p = .07), to have experienced previous interventions by child protective services (CPS) (55% vs. 17%, p < .01), to have had no prenatal care (32% vs. 6%, p = .09), and fewer prenatal visits (4.7 vs. 8.6, p = .02). Compared to screen-negative infants, more screen-positive infants were referred to a high-risk infant tracking program (91% vs. 6%), referred to CPS (100% vs. 33%), placed outside the mother's home (50% vs. 22%), and had their mothers referred to drug rehabilitation (36% vs. 11%), (p < .01 for each). By 1 year of age, support services differed little between exposed cohorts. However, 6 of 22 screen-positive infants were in foster care and 3 were placed for adoption, while only 1 of the 18 screen-negative infants was in foster care and only 1 had been placed for adoption. There were no services available in this community to provide coordinated or comprehensive services or drug treatment specific to the needs of drug using mothers and drug exposed infants. CONCLUSIONS: Despite similarities between cocaine-exposed infants cared for in a normal newborn setting (with and without positive urine drug screens at birth), differences in referral services were noted. More striking than these differences was that services for families with drug-exposed infants are inadequate to even meet the needs of those families in our setting deemed to be at highest risk. Neonatal drug screening needs to be paired with effective services.

Low literacy and violence among adolescents in a summer sports program.

PURPOSE: To investigate the relationship between inadequate literacy and violent behavior among adolescents. METHODS: This descriptive study involved a convenience sample of 386 adolescents who participated in a summer track and field and literacy program serving youths in low-income neighborhoods in Shreveport, Louisiana, during 1994-1996. Self-reported violence was measured using the Youth Risk Behavior Survey (YRBS) and reading grade levels were measured by the Slosson Oral Reading Test-Revised (SORT-R). RESULTS: Youths ranged in age from 11 to 18 years; 66% were male, and 86% were African-American. Forty-three percent of adolescents tested had below-grade reading levels (> or = 2 grades). Participants with below-grade reading skills had higher rates of self-reported violent behaviors compared with those reading at grade level. When gender, race, and age were controlled for, adolescents reading below grade level were significantly more likely to report carrying weapons [odds ratio (OR) = 1.9; 95% confidence interval (CI) 1.1-3.5], carrying guns (OR = 2.6; CI 1.1- 6.2), to have been in a physical fight at school (OR = 1.7; CI 1.1-2.6), and to have been in a physical fight resulting in injuries requiring treatment (OR = 3.1; CI 1.6-6.1). In addition, youths reading below grade level were significantly more likely to be threatened at school with a weapon (OR = 2.1; CI 1.2-3.7) and to report missing days of school in the previous 30 days because they felt unsafe at school (OR = 2.3; CI 1.3-4.3). In characterizing the violence related behaviors, we found that low reading-level adolescents were more likely to be both aggressor/perpetrator and victim (44% vs. 32%; p = .02) and less likely to be only a victim (6% vs. 12%; p = .04) compared to adolescents with grade-appropriate reading skills. CONCLUSIONS: Below-grade-level reading was significantly related to violence behaviors among adolescents who volunteered for a summer track and field program. Longitudinal studies are needed to further investigate the relationship of below-grade-level reading and aggressive/perpetrator and victim behaviors.

Adherence to AAP guidelines for well-child care under managed care. American Academy of Pediatrics.

OBJECTIVES: To determine adherence to American Academy of Pediatrics (AAP) Recommendations for Preventive Pediatric Health Care in Monroe County, New York by individual patients and individual pediatricians under managed care practice and to compare adherence-to-recommendations rates for privately insured and publicly funded managed care patients. STUDY DESIGNS AND METHODS: Using claims data for children 0 through 18 years of age cared for by pediatricians, we compared adherence to well-child care (WCC) visit recommendations for 130 572 children enrolled in a privately insured managed care system during 1992, 1993, and 1994 to 17 586 children insured by a publicly funded, Medicaid-managed care system during 1994 and 1995. Criteria for WCC visit adherence were based on 1991 AAP guidelines of 19 office visits from birth through 18 years of age. Adherence-to-recommendations rates by individual pediatricians also were determined. RESULTS: Despite complete financial coverage of WCC visits (with no co-payment or deductible charges) by both insurance systems, strict adherence to AAP guidelines for WCC visits was low. Only 46% of privately insured and 35% of publicly funded children received all the recommended visits during the study period. During the same period, 17% of privately insured and 35% of publicly funded managed care patients received no WCC. There was little difference in the rate of full WCC visit adherence by age in either system with the rates ranging in privately insured patients from 49% in infants (<2 years of age) to 47% in adolescents (12 through 18 years of age) and ranging in publicly funded patients from 36% to 34% in these two age groups, respectively. Only 2% of privately insured infants had no record of WCC compared with 29% of adolescents. This contrasted with 12% of infants and 54% of adolescents who were publicly funded. Of pediatricians, <5% achieved 100% adherence to AAP guidelines for their patients (privately insured or publicly funded). Pediatricians completed an average of 52% of the recommended visits with their publicly funded patients and 68% of the recommended visits with their privately insured patients. CONCLUSIONS: WCC visits were underutilized for children in both managed care systems. Children of parents who have low incomes presumably could benefit greatest by preventive visits, but these children were less likely to receive the recommended number of WCC visits. Finding ways to increase the number of WCC visits that all children make is a major challenge, as is conducting studies that prove their worth.

Black and white middle class children who have private health insurance in the United States.

OBJECTIVE: To compare the health, behavior and school problems, and use of medical, mental health, and special education services of privately insured, middle class black and white children in the United States. DESIGN/METHODS: Analyses of the Child Health Supplement to the 1988 National Health Interview Survey, with a nationally representative sample of 17 110 children age 0-17 years. RESULTS: Privately insured middle class black children had fewer chronic health conditions, but were less likely to be reported to be in excellent health (46.2% vs 57.3%) and more likely to have had asthma (8.5% vs 5.8%) or to have been of low birth weight (10.7% vs 5.6%). There were no differences in rates of having a usual source of routine care (92.2% vs 93.8%) or of being up to date with well-child care (79.3% vs 78.2%), but black children made fewer physician visits, were less likely to use physicians' offices, were more likely to lack continuity of care, and were twice as likely to use emergency departments. These differences in use of medical services persisted in multivariate analyses and analyses restricted to more affluent children. Despite similar rates of behavior problems, black children were more likely to repeat a grade (20.0% vs 12.3%) and to have been suspended from school (11.3% vs 5.0%). Although significantly fewer black middle class children received mental health or special education services in bivariate analyses, no differences in receipt of these services were noted in multivariate analyses. All differences reported were significant. CONCLUSIONS: Among middle class children in the United States, black and white children have similar rates of health and behavior problems, but black children experience substantially increased rates of asthma, low birth weight, and school difficulties. Although not differing in the receipt of mental health or special education services, middle class black children, even in the presence of private health insurance, have markedly different sources and patterns of use of medical services.

Resident and family continuity in pediatric continuity clinic: nine years of observation.

OBJECTIVE: To assess resident, patient, and family continuity. BACKGROUND: Continuity clinic is the principal longitudinal primary care experience for pediatric residents. Although it has been a recommendation of the Residency Review Committee for pediatric training for more than 10 years and has been a requirement of the Accreditation Council of Graduate Medical Education since 1989, the extent to which continuity is achieved in this setting has not been reported. METHODS: Nine years (1984-1993) of residents' continuity clinic experience in a community hospital affiliate of a university training program were reviewed. Continuity was defined by recurring visits between the same patient/provider pair. The analysis from 57 different residents includes 48 intern (R1) years, 45 level two (R2) years, and 40 level three (R3) years; 32 of these residents completed all 3 years of training (3-year cohort) in the program during the study period. Observations included 89 952 visits by 11 009 patients in 7130 families. Continuity was determined for the resident, patient, and family. RESULTS: Residents saw an annual average of 93, 136, and 144 visits as R1s, R2s, and R3s. Residents saw 60% of their patients fewer than 3 times and nearly 40% only once. In the final year for those in the 3-year cohort, residents saw an average of 149 visits; 53% of the time these R3s had seen their patients once or twice over 3 years. Thirty percent of the patients never saw their primary care physician (PCP) and 72% of patients had fewer than 3 visits with their PCP. One quarter of the families never saw their continuity resident, and 62% saw their continuity resident fewer than 3 times. CONCLUSIONS: These data demonstrate a remarkable lack of both resident and patient continuity in the principal clinical activity affording longitudinal primary care experiences during residency training. If more continuity is essential for both primary care of patients and education in general pediatrics, change in the structure of continuity experience is required.

Community characteristics associated with elevated blood lead levels in children.

OBJECTIVES: To identify community characteristics associated with children having elevated blood lead levels (> or = 10 micrograms/dL) and examine whether these characteristics can be used to identify children with elevated blood lead levels. PARTICIPANTS AND SETTING: A total of 20,296 children in Monroe County, New York (< 6 years old) who had blood lead testing in the first 12 months after statewide mandated reporting of blood lead tests began. DESIGN: A logistic regression analysis was conducted to examine the association of children's blood lead levels and community characteristics by using community characteristics of 653 census block groups. RESULTS: The following community level variables were associated with increased risk of elevated blood lead levels in children: residence within the city [odds ratio (OR), 2.0; 95% confidence interval (CI), 1.6, 2.7]; block groups with a higher proportion of individuals of Black race (OR, 1.6; CI, 1.4, 2.0); higher screening rate (OR, 1.9; CI, 1.6, 2.4); lower housing value (OR, 1.6; CI, 1.2, 2.0); housing built before 1950 (OR, 1.5; CI, 1.3, 1.8); higher population density (OR, 1.5; CI, 1.3, 1.8); higher rates of poverty (OR, 1.4; CI, 1.2, 1.8); lower percent of high school graduates (OR, 1.3; CI, 1.1, 1.6), and lower rates of owner-occupied housing (OR, 1.2; CI, 1.0, 1.4). Community characteristics were comparable with clinic-based individual risk assessment to identify children with elevated blood lead levels. CONCLUSIONS: These data demonstrate that community characteristics can be used to develop screening strategies to identify children who have elevated blood lead levels and shift our efforts toward identifying houses containing lead hazards before occupancy and before children are unduly exposed.

Increased behavior problems associated with delayed school entry and delayed school progress.

OBJECTIVE: To investigate whether students who are old-for-grade have higher rates of reported behavior problems and to investigate whether this association is independent of having been retained a grade in school. METHODS: Cross-sectional analyses of parental reports from the nationally representative sample of 9079 children ages 7 to 17 years who participated in the Child Health Supplement to the 1988 National Health Interview Survey. Students older than the modal age for their grade were considered old-for-grade, either due to delayed school entry (those without grade retention) or to delayed school progress (with history of grade retention). Behavior problems were defined as scores >90th percentile on a well-utilized, standardized Behavior Problem Index (BPI). RESULTS: Twenty-six percent of 7- to 17-year-old children in the United States are old-for-grade. Being old-for-grade is more common in males (31%), blacks (33%), Hispanics (32%), those living in single-parent households (31%) or poverty (43%), and those with mothers with low educational attainment (42%). Most children (84%) who repeated a grade are old-for-grade, but only 54% of old-for-grade students have been retained. For children who were old-for-grade, 19% of those grade-retained and 12% of those nonretained had extreme BPI scores, and for those not old-for-grade, 17% of grade-retained and 7% of nonretained children had extreme BPI scores. Although rates of extreme BPI scores were consistently lower for children who were neither old-for-grade nor grade-retained, and consistently higher for those with both, these rates increased with age for children who were old-for-grade without being retained. Controlling for multiple potential confounders with logistic regression, both old-for-grade status and grade retention are independently associated with increased rates of behavior problems. Separate logistic regression analyses for blacks and whites showed that these findings pertained only to white children. CONCLUSIONS: Whereas grade retention is associated with increased rates of behavior problems in children and adolescents, simply being older than others in one's class, without having experienced grade retention, is also associated with increased rates of behavior problems, most noticeably among adolescents. These data suggest that there may be latent adverse behavioral outcomes that result from delaying children's school entry.

Increasing prevalence of recurrent otitis media among children in the United States.

BACKGROUND: The number of visits for otitis media, the most common diagnosis among preschool children, has increased during the past decade. This study was undertaken to determine whether there has been a concurrent increase in the prevalence of recurrent otitis media among children in the United States and to identify risk factors or demographic changes to explain the increase. METHODS: Secondary analyses of cross-sectional data from the Child Health Supplement to the 1981 and 1988 National Health Interview Surveys (n = 5189 [1981] and n = 6209 [1988]) were done to identify temporal changes in the prevalence and any associated risk factors of recurrent otitis media among children <6 years of age. RESULTS: Recurrent otitis among preschool children increased from 18.7% in 1981 to 26% in 1988 (odds ratio [OR] = 1.6, 95% confidence interval [CI] = 1.4, 1.7). Although the prevalence of recurrent otitis increased with age, the greatest increase in recurrent otitis media occurred in infants (OR = 1.9, CI = 1.3, 2.9). Factors independently associated with recurrent otitis were any allergic condition (OR = 1. 9, CI = 1.7, 2.2); survey year (OR = 1.7, CI = 1.5, 1.9); Black race (OR = .6, CI = .5, .7); Hispanic ethnicity (OR = .8, CI = .6, .9); day care (OR = 1.5, CI = 1.3, 1.7); out-of-home care by an unrelated sitter (OR = 1.3, CI = 1.1, 1.6); and male gender (OR = 1.2, CI = 1. 1, 1.3). From 1981 to 1988, there were significant increases in some risk factors associated with recurrent otitis media, including day care (11% vs 21%) and allergic conditions (14% vs 18%). CONCLUSIONS: We conclude that there has been a significant increase in the prevalence of recurrent otitis media among children in the United States, particularly in infants. The increased prevalence of recurrent otitis media was associated with an increase in the use of child care and a higher prevalence of allergic conditions among children.

Increased drug use among old-for-grade adolescents.

OBJECTIVE: To determine whether students older than most other students at their grade level ("old for grade") are more likely to report engaging in alcohol, tobacco, and drug-related behaviors. DESIGN: Cross-sectional analyses of the Centers for Disease Control and Prevention Youth Risk Behavior Survey. SETTING: Monroe County, New York. PARTICIPANTS: A total of 1396 high school students from selected classrooms; 68 classrooms randomly selected within schools with the number of students per school proportionally selected from the 28 schools in the county. MAIN OUTCOME MEASURE: Rates of drug-related behaviors by age-for-grade status. RESULTS: Thirty-six percent of adolescents surveyed were old for grade. Adjusting for multiple potential confounders, old-for-grade high school students were more likely to report being regular smokers, chewing tobacco, drinking alcoholic beverages, driving in a car with someone who had been drinking, using alcohol or other drugs before last sexual intercourse, using cocaine in the past month, ever using crack, and using injected or other illicit drugs. CONCLUSIONS: Old-for-grade status is a potentially important marker for drug-related behaviors in adolescents. The antecedents of adolescent risk-taking behavior may begin before the teen years, and prevention of school failure or interventions targeted toward old-for-grade children could affect their propensity to experiment with or use drugs during adolescence.

The role of community health centers in providing preventive care to adolescents.

OBJECTIVES: To (1) compare preventive health visits by poor and nonpoor adolescents, (2) describe adolescent users of community health centers (CHCs), (3) investigate adolescent preventive visits to CHCs, and (4) determine factors independently associated with timely preventive visits. DESIGN: Analysis of the nationally representative sample of 6635 adolescents aged 11 to 17 years in the Child Health Supplement to the 1988 National Health Interview Survey. RESULTS: Overall, 4% of US adolescents used CHCs for routine health care, and the percentage was higher for poor compared with nonpoor adolescents (11% vs 3%, P < .01). Although CHC users were more likely to be poor (41% vs 10%, P < .001), uninsured (23% vs 10%, P < .001), and to have behavior (16% vs 9%, P = .02) and school problems (56% vs 43%, P < .001), they were as likely to have had timely preventive visits (83% vs 81%, P = .61) as adolescents who used private practices. Using logistic regression, timely adolescent preventive visits were independently associated with having a source for routine care (odds ratio, 4.1; 95% confidence interval, 3.3-5.2), a chronic health condition (odds ratio, 1.2; 95% confidence interval, 1.0-1.5), and the use of seat belts all or most of the time (odds ratio, 1.4; 95% confidence interval, 1.2-1.6), but no independent association was observed between poverty status and timely preventive visits. CONCLUSIONS: Community health centers are an important source of preventive care for impoverished adolescents. Although those who use CHCs have greater psychosocial problems, they seek preventive care as regularly as those using private practices. Thus, periodic comprehensive visits may be an effective strategy for CHCs to provide preventive services to adolescents.

Illicit substance use, gender, and the risk of violent behavior among adolescents.

OBJECTIVES: To analyze data from a nationally representative sample of high school students to investigate the relationship between substance use and violent behavior among adolescents and to examine this relationship in both male and female adolescents. DESIGN: Cross-sectional analyses of the 1991 Centers for Disease Control and Prevention's Youth Risk Behavior Survey. SETTING: Public and private schools in the 50 states. PARTICIPANTS: The participants were 12,272 high school students. MAIN OUTCOME MEASURE: To determine the prevalence of weapon carrying and physical fighting among male and female adolescents. RESULTS: A significant increase in the number of male and female adolescents carrying weapons and physically fighting was associated with all forms of substance use. Reports of carrying a weapon increased with recent alcohol consumption (34% vs 17%, P < .001) and use of marijuana (48% vs 22%, P < .001), cocaine (71% vs 25%, P < .001), and anabolic steroids (62% vs 25%, P < .001). The prevalence of physical fighting was also significantly higher among adolescents who used illicit substances than among adolescents who denied drug use. The risk of violent behavior increased significantly, and was of equal magnitude, for adolescent females and males who were illicit substance users. CONCLUSIONS: Alcohol and illicit substance use are highly associated with an increased risk of violent behavior. These data also demonstrate that the risk of violence by adolescent females who are substance users is substantial.

Bed-wetting in US children: epidemiology and related behavior problems.

OBJECTIVE: To better understand the epidemiology and behavioral correlates of bed-wetting in a nationally representative sample of children. METHODS: Bivariate and multivariate logistic regression analyses of cross-sectional data regarding 10 960 children aged 5 through 17 years from the 1981 Child Health Supplement to the National Health Interview Survey. Behavior problems were determined by extreme scores on a 32-item Behavior Problem Index (BPI, > 90th percentile). RESULTS: Bed-wetting was reported in 33% of 5-, 18% of 8-, 7% of 11-, and 0.7% of 17-years-olds. At all ages, infrequent bed-wetting (fewer than six episodes per year) accounted for half of all reported bed-wetting. Lower age, male gender, and extreme scores on the BPI all were independently associated with both infrequent and frequent bed-wetting. Extreme scores on the BPI were more common among children with bed-wetting than those who did not wet the bed, and the risk for this was similar among children with infrequent and frequent bed-wetting (adjusted odds ratios, 1.8 and 1.7, respectively). Parents' perceived need for help with emotional and behavioral problems, however, was increased only among children with frequent bed-wetting. CONCLUSIONS: Bed-wetting in children aged 5 years and older, irrespective of its frequency, is associated with increased rates of behavior problems. Thus, although infrequent bed-wetting may not warrant medical intervention, this condition should prompt health care providers to explore behavioral issues in greater depth.

Profile of uninsured children in the United States.

OBJECTIVES: To describe the demographic characteristics, utilization of medical services, and health status of uninsured children compared with insured children in the United States and to assess the factors associated with lack of health insurance among children. An estimated 8 million children in the United States are uninsured. Medicaid expansions and tax credits have had little impact on the overall problem. An understanding of the characteristics of uninsured children is essential for the design of appropriate outreach and enrollment strategies, benefit packages, and health care provision arrangements for uninsured children. METHODS: Analysis of the 1988 Child Health Supplement of the National Health Interview Survey. RESULTS: Diverse groups of children in the United States lack health insurance. Residence in the South (odds ratio [OR], 2.3) and West (OR, 1.9. [corrected]) and being poor (OR, 2.2) or nearly poor (OR, 2.1) are independently associated with being uninsured. Substantial differences in both sources of care and utilization of medical services exist between uninsured and insured children. Uninsured children lack usual sources of routine care (OR, 3.1) and sick care (OR, 3.8) and also lack appropriate well-child care (OR, 1.5) compared with insured children. Neither being in fair or poor health nor emergency department use are significant independent predictors of being uninsured among children. Children who have a chronic disease, such as asthma, face difficulties of access to care and utilize substantially fewer outpatient and inpatient services. CONCLUSIONS: Universal health insurance, rather than efforts directed at specific groups, appears to be the only way to provide health insurance for all US children. Uninsured and insured children reveal marked discrepancies in access to and utilization of medical services, including preventive services, but have similar rates of chronic health conditions and limitations of activity. Uninsured children do not appear to form a population that will incur higher mean annual expenditures for medical care compared with insured children.

A cluster of anaphylactic reactions in children with spina bifida during general anesthesia: epidemiologic features, risk factors, and latex hypersensitivity.

BACKGROUND: Anaphylactic reactions (ARs) in high-risk pediatric patients undergoing general anesthesia, especially those with spina bifida, have been attributed to anesthetics, muscle relaxants, antimicrobials, ethylene oxide, and latex. METHODS: To identify risk factors for AR during general anesthesia and to investigate the role of latex allergy, we studied epidemiologic and immunologic characteristics of patients with ARs during general anesthesia during a 13-month cluster of such reactions at Children's Hospital of Wisconsin (case patients). Patients with AR were compared with patients with spina bifida undergoing uneventful general anesthesia during the same period (control patients). For each case patient and control patient, we conducted a chart review; a parental interview; skin prick testing with latex, anesthetics, aeroallergens, and banana extract; ELISA and RAST for latex-specific IgE; a total serum IgE; and an ELISA for IgE antibody to ethylene oxide. RESULTS: Anaphylactic reactions occurred exclusively in patients with spina bifida (n = 10) or patients with a congenital urinary tract anomaly (n = 1). Case-patients were more likely than control patients to have a history of asthma (p = 0.002), rubber contact allergy (p = 0.001), food allergy (p = 0.001), rash caused by adhesive tape (p = 0.05), daily rectal disimpaction (p < 0.001), nine or more prior surgical procedures (p < 0.002), latex-specific IgE (p = 0.027), or elevated total serum IgE levels (p = 0.002). Multivariate analysis identified non-white race, rubber contact allergy, history of food allergy, and nine or more surgical procedures as significant independent risk factors. Logistic model equation identified the predicted probability of AR with a sensitivity, specificity, and positive predictive value of 82%, 97%, and 82%, respectively. CONCLUSIONS: These findings demonstrate that atopy, especially symptomatic latex allergy, is associated with AR during anesthesia in patients with spina bifida. Until a standardized latex test is available, a medical history of immediate rubber contact allergy, non-white race, food allergy, or nine or more prior surgical procedures can identify patients with spina bifida at highest risk for ARs. A complete history, including rubber contact and food allergy, should be compiled on all patients with spina bifida before surgery.

Predictors of early grade retention among children in the United States.

BACKGROUND: Despite increasing concerns regarding school readiness, little is known about child health correlates of early school failure among the general child population. The results of this study, conducted to investigate health and social factors associated with early grade retention in a nationally representative sample of children in the United States, are reported here. DESIGN: Analyses of data derived from interviews with parents of 9996 children ages 7 to 17 years who participated in the Child Health Supplement to the 1988 National Health Interview Survey. MAIN OUTCOME MEASURES: History of repeating kindergarten or first grade. RESULTS: Nationally, 7.6% of children repeated kindergarten or first grade. In a logistic regression model, factors independently associated with increased risk of grade retention were: poverty [Odds Ratio (OR) 1.7, 95% confidence interval (CI) 1.4, 2.1], male gender (OR 1.5, CI 1.3, 1.9), low maternal education (OR 1.4, CI 1.1, 1.8); deafness (OR 1.9, CI 1.4, 2.6), speech defects (OR 1.7, CI 1.1, 2.6), low birth weight (OR 1.6, CI 1.2, 2.2), enuresis (OR 1.6, CI 1.1, 2.2), and exposure to household smoking (OR 1.4, CI 1.1, 1.7). High maternal education (OR 0.6 CI 0.4, 0.9) and residence with both biological parents at age 6 years (OR 0.7, CI 0.6, 0.9) were independently associated with a decreased risk of retention. Recurrent otitis media, black race, and low maternal age, although associated with early grade retention in bivariate analyses, were not independently associated with grade retention in a model that controls for these other factors and for the age cohort of the child. Although omitted from the above predictive model because of uncertainty about its temporal relation to early grade retention in this dataset, behavior problems at the time of interview have a strong independent association (OR 1.9, CI 1.5, 2.5) with prior early retention. CONCLUSIONS: This is the first study that uses national data to investigate how health and social factors individually and collectively contribute to early grade retention. It demonstrates that early retention is common, that a number of extremely common child health problems are independently associated with it, and that the magnitude of the heightened risk associated with these problems is similar to that of many of the well-recognized and difficult to change family and social risk factors for early retention. The successful implementations of Pub L 99-457 (The Education for All Handicapped Children Act Amendments of 1986) services in communities nationwide, and the improvement in the educational performance of large numbers of children will be facilitated by pediatricians' advocacy and surveillance for problems that place children at risk for educational failure, and by effective referral to and collaboration with nonpediatric child and family services.
