Impact of low birth weight on early childhood asthma in the United States.

OBJECTIVE: To estimate the independent contribution of birth weight to asthma prevalence among children younger than 4 years in the United States and to compare the magnitude of its effect on asthma between African American and white children. DESIGN: Cross-sectional analysis using the 1988 National Maternal-Infant Health Survey and 1991 Longitudinal Follow-up Survey. SETTING: United States. PATIENTS: Eight thousand seventy-one subjects, selected from a randomized, systematic population-based sample and weighted to be nationally representative, who completed both initial and longitudinal follow-up surveys and reported information on asthma diagnosis. MAIN OUTCOME MEASURES: Birth weight and other sociodemographic factors linked to birth outcome were analyzed for independent association with physician-diagnosed asthma by age 3 years. RESULTS: The prevalence of asthma varied by birth weight category: 6.7% in children 2500 g or more at birth, 10.9% in children 1500 to 2499 g at birth, and 21.9% in children less than 1500 g at birth (very low birth weight [VLBW]) (P<.001). Some of the characteristics shown to be independently associated with asthma included: VLBW (odds ratio [OR], 2.9; 95% confidence interval [CI], 2.3-3.6), moderately low birth weight (OR, 1.4; 95% CI, 1.1-1.8), and African American race (OR, 1.9; 95% CI, 1.6-2.4). In stratified analyses, the independent association between VLBW and asthma in white and African American populations was: OR(white), 3.1 (95% CI, 2.2-4.3) and OR(African American), 2.5 (95% CI, 2.0-3.3). The prevalence of VLBW, however, was tripled in African American compared with white children (1.8% vs 0.6%). CONCLUSIONS: These data confirm findings of other studies that identify a strong independent association between low birth weight and asthma. For this 1988 national birth cohort, an estimated 4000 excess asthma cases were attributable to birth weight less than 2500 g. Although the strength of the independent association between VLBW and asthma was smaller in the African American population, the substantially increased prevalence of VLBW in this community may contribute to the disproportionately increased prevalence of asthma among African American children.

Residential exposures associated with asthma in US children.

OBJECTIVE: Residential exposures are recognized risk factors for childhood asthma, but the relative contribution of specific risk factors and the overall contribution of housing to asthma in US children is unknown. The objective of this study was to identify risk factors and estimate the population attributable risk of residential exposures for doctor-diagnosed asthma for US children. METHODS: A cross-sectional survey was conducted from 1988 to 1994. Survey participants were 8257 children who were <6 years old and who participated in the Third National Health and Nutrition Examination Survey, a survey of the health and nutritional status of children and adults in the United States. The main outcome measure was doctor-diagnosed asthma, as reported by the parent. RESULTS: Six percent of children had doctor-diagnosed asthma. The prevalence of asthma was higher among boys (6.7%) than girls (5.1%) and was higher among black children (8.9%) than white children (5.2%). Risk factors for doctor-diagnosed asthma included a family history of atopy (odds ratio [OR]: 2.2; 95% confidence interval [CI]: 1.5, 3.1), child's history of allergy to a pet (OR: 24.2; 95% CI: 8.4, 69.5), exposure to environmental tobacco smoke (OR: 1.8; 95% CI: 1.2-2.6), use of a gas stove or oven for heat (OR: 1.8; 95% CI: 1.02-3.2), and presence of a dog in the household (OR: 1.6; 95% CI: 1.1, 2.3). The population attributable risk of >/=1 residential exposure for doctor-diagnosed asthma in US children <6 years old was 39.2%, or an estimated 533 000 excess cases, whereas having a family history of atopy accounted for 300 000. The attributable cost of asthma as a result of residential exposures for children <6 years old was $402 million (95% CI: $296-$507 million) annually. CONCLUSIONS: The elimination of identified residential risk factors, if causally associated with asthma, would result in a 39% decline in doctor-diagnosed asthma among US children <6 years old.

Risk factors for pediatric asthma. Contributions of poverty, race, and urban residence.

The Child Health Supplement to the 1988 National Health Interview Survey was used to examine parent-reported current asthma among a nationally representative sample of 17,110 children zero to 17 yr of age. Numerous demographic variables were analyzed for independent associations with asthma using modified stepwise logistic regression, with models including specific combinations of risk factors. Black children had higher rates of asthma than did white children in unadjusted analyses, but after controlling for multiple factors, black race was not a significant correlate of asthma (adjusted odds ratio = 0.87, 95% CI = 0.63 to 1.21). Compared with nonurban white children, urban children, both black and white, were at significantly increased risk of asthma: urban and black (adjusted OR = 1.45, 95% CI = 1.14 to 1.86), urban and white (adjusted OR = 1.22, 95% CI = 1.01 to 1.48), whereas nonurban black children were not: nonurban and black (adjusted OR = 1.15, 95% CI = 0.83 to 1.61). Similarly, compared with nonurban, nonpoor children, urban and poor (adjusted OR = 1.44, 95% CI = 1.05 to 1.95), urban and nonpoor (adjusted OR = 1.22, 95% CI = 1.004 to 1.48), urban children, both poor and nonpoor, were at significantly increased risk of asthma, whereas nonurban poor children were not: nonurban and poor (adjusted OR = 1.03, 95% CI = 0.72 to 1.48). These results suggest that the higher prevalence of asthma among black children is not due to race or to low income per se, and that all children living in an urban setting are at increased risk for asthma.

Inadequate therapy for asthma among children in the United States.

OBJECTIVE: Childhood asthma morbidity and mortality are increasing despite improvements in asthma therapy. We hypothesized that a substantial number of children with moderate to severe asthma are not taking the maintenance medications recommended by national guidelines. The objective of this study was to describe medication use among US children with asthma and determine risk factors for inadequate therapy. METHODS: The National Health and Nutrition Examination Survey (NHANES) III 1988-1994 provided cross-sectional, parent-reported data for children 2 months to 16 years of age. Analysis focused on children with moderate to severe asthma (defined as having any hospitalization for wheezing, >/=2 acute visits for wheezing, or >/=3 episodes of wheezing over the past year). We defined these children as adequately treated if they had taken a maintenance medication (inhaled corticosteroid, cromolyn, or theophylline) during the past month. Demographic variables were analyzed for independent associations with inadequacy of therapy. The statistical analysis used SUDAAN software to account for the complex sampling design. RESULTS: A total of 1025 children (9.4%) had physician-diagnosed asthma. Of those with moderate to severe asthma (n = 524), only 26% had taken a maintenance medication during the past month. Even among children with 2 or more hospitalizations over the previous year, only 32% had taken maintenance medications. In a logistic regression analysis, factors significantly associated with inadequate therapy included: age </=5 years, Medicaid insurance, and Spanish language. Children surveyed after 1991, when national guidelines for asthma management became available, were no more likely to have taken maintenance medications than children surveyed before 1991. CONCLUSION: Most children with moderate to severe asthma in this nationally representative sample, including those with multiple hospitalizations, did not receive adequate asthma therapy. These children may incur avoidable morbidity. Young children, poor children, and children from Spanish-speaking families appear to be at particularly high risk for inadequate therapy.

'Paradoxical' alpha synchronization in a memory task.

The results of a specially designed memory search paradigm which maximizes episodic short-term memory (STM) and minimizes semantic long-term memory (LTM) demands show that the upper alpha band synchronizes selectively in those conditions and time intervals where episodic STM demands are maximal. This finding of a selective alpha synchronization occurring only in the upper alpha band and during highest task demands is surprising because it is well known that usually alpha desynchronizes during mental activity. Because experiments from our laboratory indicate that desynchronization in the upper alpha band is related to semantic LTM processes, the present finding suggests that a selective synchronization in this frequency band reflects inhibition of semantic LTM. It is assumed that once the capacity limits of STM are reached or exceeded, processing resources are no longer distributed and that potentially interfering, task irrelevant, brain areas or processing systems are inhibited.

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.

Primary prevention of childhood lead exposure: A randomized trial of dust control.

BACKGROUND: Dust control is recommended as one of the primary strategies to prevent or control children's exposure to residential lead hazards, but the effect of dust control on children's blood lead levels is poorly understood. OBJECTIVE: To determine the effectiveness of dust control in preventing children's exposure to lead, as measured by blood lead levels, during their peak age of susceptibility. DESIGN: A randomized, controlled trial. SETTING: Rochester, NY. PARTICIPANTS: A total of 275 urban children were randomized at 6 months of age, of whom 246 (90%) were available for the 24-month-old follow-up visit. INTERVENTIONS: Children and their families were randomly assigned to an intervention group (n = 140), which received cleaning equipment and up to eight visits by a dust control advisor, or a control group (n = 135). OUTCOME MEASURES: Geometric mean blood lead levels and prevalence of elevated blood lead levels (ie, >10 microg/dL, 15 microg/dL, and 20 microg/dL). RESULTS: At baseline, children's geometric mean blood lead levels were 2.9 microg/dL (95% confidence interval [CI] = 2.7, 3.1); there were no significant differences in characteristics or lead exposure by group assignment, with the exception of water lead levels. For children in the intervention group, the mean number of visits by a dust control advisor during the 18-month study period was 6.2; 51 (36%) had 4 to 7 visits, and 69 (49%) had 8 visits. At 24 months of age, the geometric mean blood lead was 7.3 microg/dL (95% CI = 6.6, 8.2) for the intervention group and 7.8 microg/dL (95% CI = 6.9, 8. 7) for the control group. The percentage of children with a 24-month blood lead >/=10 microg/dL, >/=15 microg/dL, and >/=20 microg/dL was 31% versus 36%, 12% versus 14%, and 5% versus 7% in the intervention and control groups, respectively. CONCLUSIONS: We conclude that dust control, as performed by families and in the absence of lead hazard controls to reduce ongoing contamination from lead-based paint, is not effective in the primary prevention of childhood lead exposure.

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.

Theta synchronization in the human EEG and episodic retrieval.

Event-related desynchronization (ERD) and synchronization (ERS) was measured during episodic retrieval in a specially designed recognition task which forces subjects to avoid semantic search strategies. ERD represents the percentage of a decrease, ERS an increase in band power. The results show that only the theta band differentiates between good and bad episodic memory performers and that good performance is related to a large degree of theta synchronization. The delta and alpha bands did not yield significant effects. Topographical differences in theta ERS reveal that good performers use primarily their right hemisphere to retrieve episodic information. This finding agrees with respective results from PET studies.

Risk factors for the early acquisition of human herpesvirus 6 and human herpesvirus 7 infections in children.

OBJECTIVE: Human herpesviruses 6 and 7 (HHV-6 and HHV-7) are common infections in children, but risk factors for their early acquisition have not been described. METHODS: Excess sera from children 12 to 31 months of age enrolled in a cross-sectional, random survey were tested for human herpesviruses 6 and 7 infection, as measured by using immuno-blot and immunofluorescence assays. RESULTS: Of 164 children 131 (80%) had antibody to HHV-6, and 79 (47%) of 167 had antibody to HHV-7. In logistic regression analysis low income [odds ratio (OR), 2.9; 95% confidence intervals (CI), 1.02 to 8.7] and having more than 1 sibling (OR=2.1, 95% CI=0.9 to 5.1) were risk factors for HHV-6 infection after adjusting for age, whereas month of test (OR=2.7, 95% CI=1.3 to 5.9) and Black race (OR=2.0, 95% CI=0.9, 4.6) were associated with a higher prevalence of HHV-7 infection. In contrast having ever been breast-fed appeared to protect against HHV-7 infection (OR=0.5, 95% CI=0.3 to 1.1). CONCLUSIONS: Despite studies linking both HHV-6 and HHV-7 with exanthem subitum, risk factors for the early acquisition of HHV-6 and HHV-7 are distinct. Subsequent studies investigating the transmission of HHV-6 should explore family size and other factors associated with poverty, whereas breast-feeding should be examined as a protective factor for HHV-7 infection.

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.

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.
