Sexual behavior, contraception, and risk among college students.

PURPOSE: To characterize the differences and similarities among college freshmen, sophomores, juniors, and seniors regarding their sexual behavior including contraception choices and human immunodeficiency virus (HIV) risk. METHODS: A 41-item sexual behavior questionnaire designed for this study was administered to a convenience sample (N = 797) of a college population. RESULTS: Levels of sexual activity were found to be comparable to other college-based surveys. Notable trends included an increased level of oral contraceptive use among partners reported by seniors, as compared to freshmen, without a corresponding increase in condom use; an increased reliance among seniors, as compared to freshmen, on women to provide contraception; and a low level of self or partner HIV testing either before or after initiating sexual intercourse. Gender differences also revealed greater partner relationship duration, intensity, and communication prior to initiating sexual intercourse among women versus men (p < or = .001). CONCLUSIONS: Sexual behavior among college students differs across the 4 years with regard to rates of intercourse, contraception choice, and responsibility, as well as HIV testing and partner trust. University- and college-based health care programs should address sexual behavior with an awareness of the differences that exist in the four cohorts of students.

PIP: This study aimed to describe the differences and similarities among college freshmen, sophomores, juniors, and seniors concerning their sexual behavior, including contraception choices and HIV risk. The sample (N = 797; mean age = 19 years) were taken from a private 4-year undergraduate college and represented 17% of the college population. It consisted of 474 (60%) females and 318 (40%) males. They were interviewed through the use of a 41-item questionnaire administered in a cross-sectional survey design. In the results, levels of sexual activity were similar to other college-based surveys with 72% reporting ever having had sexual intercourse. The average age of first sexual intercourse was 16.8 years for females and 16.7 for males; 358 (45%) were currently sexually active. Condoms were the most common contraception used, followed by oral contraceptives. The primary purpose in choosing a contraceptive was prevention of both pregnancy and disease. Seniors had increased level of oral contraceptive use and increased reliance on women to provide contraception as compared to freshmen. The percentage of students who had undergone HIV testing also increased from freshman (16%) to senior (32%) years. As to gender differences, women reported greater partner relationship duration, intensity, and communication prior to initiating sexual intercourse as compared to men. In conclusion, college-based health care programs should address sexual behavior with an awareness of the differences that exist in the 4 cohorts of students.

Increase in admission threshold explains stable asthma hospitalization rates.

BACKGROUND: Asthma morbidity and mortality has increased substantially in recent years, but asthma hospitalization rates among many geographic and sociodemographic groups have remained stable. Observations on asthma hospitalization rates and severity of acute episodes might provide valuable insight into the functioning of the health care system during this period of health care reform. OBJECTIVE: To analyze changes between 1991 and 1995 in childhood asthma hospitalization rates and severity of acute episodes. DESIGN AND METHODS: All 29 329 hospitalizations, including 2028 for asthma, for the 198 893 children (<19 years of age) in Monroe County (Rochester), New York, were studied during this 5-year period. Severity was determined by hospital record review on a 22% random sample. Using the worst oxygen saturation (SaO(2)) during the first 24 hours of hospitalization as the primary index of severity, episodes were categorized as mild (0 to >/=95), moderate (90 to 94), or severe (<90). RESULTS: Hospitalization rates are expressed as hospitalizations per 1000 child-years. The overall asthma hospitalization rate was 2.04 (95% confidence interval, 1.95-2.13). The overall annual asthma hospitalization rate remained relatively stable from 1991 (1.90) to 1995 (2.31), whereas the hospitalization rates for severe asthma rose 270%-from 0.57 to 1.55-during this period. Simultaneously, the hospitalization rates for mild asthma decreased from 0.26 to 0.12. As a proportion of all asthma hospitalizations between 1991 and 1995, severe episodes increased from 31.5% to 60.4%; conversely, mild episodes decreased from 14.1% to 4.7%. CONCLUSIONS: Severity increased significantly among children hospitalized for asthma while the overall asthma hospitalization rate remained stable. It seems that the health care system in this community has responded to an increase in severity of asthma by raising the severity threshold for admission.

Socioeconomic variation in asthma hospitalization: excess utilization or greater need?

OBJECTIVE: To assess the hypothesis that higher incidence of severe acute asthma exacerbation, not lower severity threshold for admission, explains the difference between the asthma hospitalization rates of inner-city and suburban children. METHODS: All 2028 asthma hospitalizations between 1991 and 1995 for children (aged >1 month and <19 years) dwelling in Rochester, New York, were analyzed. ZIP codes defined residences as inner-city, other urban, or suburban. Based principally on the worst oxygen saturation (SaO2) during the first 24 hours of hospitalization, severity was examined by hospital record review (n = 443) of random samples of inner-city, other urban, and suburban asthma admissions. RESULTS: Large inner-city/suburban differences were noted in many sociodemographic attributes, and there was also a distinct, stepwise gradient in risk factors in moving from the suburbs to other urban areas and to the inner city. Racial and economic segregation was particularly striking. Black individuals accounted for 62% of inner-city births versus <3% in the suburbs. Medicaid covered 65% of inner-city births, whereas Medicaid covered only 6% of suburban births. The overall asthma hospitalization rate was 2.04 admissions/1000 child-years. Children <24 months old, those most commonly hospitalized for asthma, were fourfold more likely to be hospitalized (OR: 3.97, 95% CI: 3. 44-4.57) than children between the ages of 13 and 18 years. The hospitalization rate of asthma in boys was almost twice the rate of asthma in girls. The greatest gender difference was observed among children who were <24 months old. For these children, the rate for boys was 6.10/1000 child-years compared with 2.65/1000 child-years for girls (OR: 2.31, 95% CI: 1.95-3.03). This gender difference diminished gradually in older age groups to the extent that there was no difference among girls and boys between the ages of 13 and 18 years (males, 1.12/1000 child-years vs females, 1.09/1000 child-years). Based on worst SaO2 values, mild (worst SaO2 >/=95%), moderate (90%-94%), and severe (<90%) admissions constituted 10.3%, 41.9%, and 47.7% of all hospitalizations, respectively. Although rates within the community followed a distinct geographic pattern of suburban (1.05/1000 child-years) < other urban (2.99/1000 child-years) < inner-city (5.21/1000 child-years), the proportions of admissions with low severity did not vary among areas. Likewise, the proportions of admissions that were severe (SaO2 <90%) were not significantly different (44.8, 45.7, and 52.1% for suburban, other urban, and inner-city areas, respectively). The distributions of asthma severity, measured by the duration of frequent nebulized bronchodilator treatments and the length of hospital stay, were also similar among children from different socioeconomic areas. CONCLUSION: The marked socioeconomic and racial disparity in Rochester's asthma hospitalization rates is largely attributable to higher incidence of severe acute asthma exacerbations among inner-city children; it signals greater need, not excess utilization. Both adverse environmental conditions and lower quality primary care might explain the higher incidence. Interventions directed at the environment offer the possibility of primary prevention, whereas primary care directed at asthma is focused on secondary prevention, principally on improved medication use. Higher hospitalization rates cannot be assumed to identify opportunities for cost reduction. The extent to which our observations about asthma hold true under other conditions and in other communities warrants systematic attention. Knowledge of when higher rates signal excess utilization and when, instead, they signify greater needs should guide equitable national health policy.

How commonly are children hospitalized for asthma eligible for care in alternative settings?

OBJECTIVE: To estimate the proportion of children hospitalized for acute asthma exacerbation who might be cared for successfully in alternative settings such as short-stay units or in-home nursing. DESIGN: Descriptive study based on analysis of hospital discharge files and on retrospective medical record review of a random sample of asthma hospitalizations. METHODS: The 2028 asthma hospitalizations between 1991 and 1995 for children (aged <19 years) dwelling in Rochester, NY, were studied. Measures included the duration of frequent administration of nebulized medication (2 or more times in a 4-hour period), worst oxygen saturation levels, deterioration, and hospital length of stay. Oxygen saturation values and nebulized medication frequency were determined by hospital record review on a random sample of 443 asthma episodes. Length of stay was available for all admissions. RESULTS: Worst oxygen saturation following hospital admission was 95% or greater, 90% to 94%, and less than 90% for 21.3%, 51.6%, and 27.1% of episodes, respectively. Children received frequent nebulized medication treatments for a mean of 2.0 nursing shifts (8 hours per shift), although they remained hospitalized, on average, for 4.3 nursing shifts longer. Deterioration to a critical level of severity was uncommon. Among children initially admitted to the regular pediatric inpatient unit, only 0.7% subsequently deteriorated to the point that they were transferred to the critical care unit. CONCLUSION: More than 70% of asthma hospitalizations in this community could be cared for in alternative settings with supplemental oxygen, nebulized medication treatments, and close nursing observation provided, in most cases, for 2 nursing shifts.

Early effects of a school-based human immunodeficiency virus infection and sexual risk prevention intervention.

OBJECTIVE: To determine the short-term effect of a middle and high school-based human immunodeficiency virus and sexuality intervention (Rochester AIDS Prevention Project for Youth [RAPP]) on knowledge, self-efficacy, and behavior intention. DESIGN: Nonrandomized intervention study with 2 intervention groups and 1 control group. SETTING: Middle and high school health classes in an urban, predominantly minority school district. PARTICIPANTS: Middle and high school students (N = 3635) enrolled in health classes in 9 schools; 50% African American, 16% Hispanic, 20% white, and 14% other. Less than 10% of students refused participation. INTERVENTION: There were 3 study conditions: (1) Control, usual health education curriculum taught by classroom teacher; (2) RAPP adult health educator, intervention curriculum implemented by ethnically diverse male-female pairs of highly trained health educators; and (3) RAPP peer educator, intervention implemented by male-female pairs of extensively trained high school students. Health classes within schools were assigned to 1 of the 3 conditions each semester, and simultaneous implementation of the control program with health educators or peer educators in the same school and during the same semester was not permitted. MAIN OUTCOME MEASURE: A confidential questionnaire administered to all study subjects before and immediately after the intervention, containing scales to measure knowledge, sexual self-efficacy, and safe behavior intention. RESULTS: Preintervention data indicated that the study population was involved in sexual activity and other risk behaviors at rates comparable to those of other urban adolescent populations. Examination of 3 outcome constructs as dependent variables (knowledge, sexual self-efficacy, and safe behavior intention) revealed that the health educators and peer educators increased students' knowledge significantly more than did the control condition for both middle (females, P<.01; males, P<.01) and high (females, P<.001; males, P<.001) school. Comparisons of self-efficacy changes across intervention groups did not reach statistical significance, and safe behavior intention changes differed significantly by intervention group for high school but not for middle school students. For all analyses, the preintervention scores for each outcome variable were the most powerful predictors of postintervention scores, and analysis of variance models predicted substantial overall variance. CONCLUSIONS: At short-term follow-up, the RAPP intervention had a powerful effect on knowledge for all students and a moderate effect on sexual self-efficacy and safe behavior intention, particularly for high school students. The peer educators were found to be equally and, for some variables, more effective than the highly trained adult educators. The substantial effect of the baseline scores and the high prevalence of risk behavior already evident by seventh grade indicate the importance of early implementation of school-based sexuality programs.

Self-reported honesty among middle and high school students responding to a sexual behavior questionnaire.

PURPOSE: To determine self-reported honesty in completing a sexual and other risk behavior questionnaire among middle and high school students, and to relate honesty scores to sexual behavior item responses as a method to detect bias in reporting. METHODS: A self-administered questionnaire measuring overall honesty (7-point rating scale), sexual honesty (5-category scale), and selected sex behaviors was used. Urban, predominantly minority middle and high schools (Grades 7-12) were examined, and participants were 3144 male and female students in middle (mean age = 13.7 +/- 2.0) and high (17.3 +/- 1.6) school health classes. RESULTS: The majority of students stated that they had been very or completely honest in responding to items on the questionnaire. Seventy-eight percent of middle school males (lowest rate), and 94% of high school females (highest rate) reported honesty. Middle school males were most likely to declare dishonesty regarding sexual behavior items, overstating their actual behavior (14%), while middle school girls were most likely to understate (8%) their behavior. Self-reported sexual honesty and reports of behavior were most consistent for understaters. That is, those subjects who answered that their questionnaire responses underreported their true sexual behavior did, in fact, report lower sexual activity on selected survey items. CONCLUSION: Middle and late adolescents reported high levels of honesty in responding to a sexuality-related questionnaire. When interpreting such questionnaire data, correction for the tendency to overstate among middle school males and understate among middle school females should be considered; conclusions about self-reports of sexual behavior among young adolescents need to take into account degree of honesty. However, the presence of some overreported and some underreported behavior does not invalidate interpretation of the overall survey findings.

Estimating risk associated with care in alternative settings: deterioration among children hospitalized.

BACKGROUND: Although managed care favors use of alternative settings in an attempt to avoid hospitalization, uncertainty about possible deterioration creates concern about their safety. OBJECTIVE: To derive preliminary estimates for the risk of adverse outcome in children hospitalized with acute illness who met criteria for admission to potentially less-expensive, alternative settings (eg, short-stay unit, home nursing). DESIGN: Description of hospitalization outcomes for a community-wide childhood population. SETTING AND POPULATION: All 11591 hospitalizations for residents of Monroe County (Rochester), New York, aged 1 month to 18 years in 1991 and 1992. MEASUREMENTS: To identify potential adverse outcomes in alternative settings (numerator estimate), hospital medical records for admissions to regular inpatient units were examined. To ascertain deterioration among these admissions, detailed record reviews were conducted if the child died or was transferred to another hospital or to a critical care unit. To estimate the total number of admissions eligible for care in alternative settings (denominator estimate), hospital discharge files were analyzed. RESULTS: Deterioration was found in 83 medical admissions. Of these 83, major chronic problems (n=53) or severe illness at presentation (n=27) precluded alternative setting eligibility, leaving only 3 in whom alternative setting care might have been considered. The total number of admissions eligible for alternative setting care was estimated between 1661 (restrictive criteria) and 3322 (inclusive criteria) for the 2-year observation period. Based on these observations, best- and worst-case estimates for the risk of deterioration in candidates for care in alternative settings were 0.6 and 1.8 per 1000, respectively. For the 3 children for whom alternative setting care might have been considered, the shortest period from first indication of deterioration to arrival in the critical care unit was 3.0 hours. CONCLUSIONS: These preliminary estimates suggest that alternative settings may be safe for the care of many children currently hospitalized. A randomized clinical trial to evaluate directly the potential benefits and harms of alternative setting care should be considered.

Diagnostic clusters in infants as child health outcomes. Variation among socioeconomic areas in one community.

Objectives were to examine geographic variation in rates of infant hospitalization for diagnostic clusters in Monroe County (Rochester), New York and to assess these clusters as indexes of child health. ICD-9 codes were used to cluster all 7,883 hospitalizations of infants (< 24 months) between 1985 and 1991 on the basis of their avoidability. Environmentally sensitive clusters accounted for 63% of admissions. These clusters included environmental, environmental/constitutional, and other infectious disease. Disparities in morbidity between inner city and suburbs were greatest for the environmental cluster, followed by the environmental/constitutional, and other infectious disease clusters. For the constitutional and quality indicator clusters, differences between inner-city and suburban risk were minimal. Environmental interventions may be more important than improved health services to reducing racial and economic disparities in child health. Analysis of morbidity clusters, ascertained from available administrative data bases and aggregated for small geographic areas, may guide child health policy well.

Sibling Adaptation to Childhood Cancer Collaborative Study: the association of sibling adaptation with maternal well-being, physical health, and resource use.

This multi-institutional study investigated the association of behavioral/emotional adaptation among siblings of children with cancer with maternal general well-being, physical health, and resource use. One hundred seventy siblings and mothers completed standardized interviews and self-report measures 6 to 42 months after the cancer was diagnosed. As a group, mothers of children with cancer reported significantly lower levels of well-being than matched controls. When stratified according to the level of the sibling's behavioral/emotional adaptation, mothers of siblings in the Dysfunctional group (1) reported the lowest levels of well-being; (2) during the preceding year, were more likely to have sought professional services than mothers of children in the Resilient group; and (3) were least likely to have found social support helpful. Our results support an association between maternal well-being and sibling adjustment but show it is unlikely that nonspecific social support will improve adjustment. The rationale for problem-solving training for mothers is provided.

Decline of pediatric admissions with Haemophilus influenzae type b in New York State, 1982 through 1993: relation to immunizations.

OBJECTIVES: To evaluate the impact of vaccination for Haemophilus influenzae type b (Hib) on pediatric hospital admissions in New York State, and to identify risk factors in children who continue to be admitted for Hib invasive disease. METHODS: Retrospective review of hospitalizations in New York state from 1982 through 1993 and a survey of immunization records from physician offices in Monroe Country, New York. RESULTS: In 1982, 769 children were admitted to New York state hospitals for Hib-related conditions; by 1993, this had decreased to 133. Significant declines during the study period occurred in the age-adjusted admission rates for Hib meningitis, septicemia, pneumonia, and epiglottitis, but not for arthritis and osteomyelitis. In 1993 alone, 712 admissions, 18 deaths, and 135 episodes of morbidity were avoided. Since 1991, the rates of admissions for Hib-related conditions have remained fairly constant. Minority subjects continue to be twice as likely as white subjects to be admitted for invasive Hib disease (0.44 vs 0.17/100,000). Children living in urban Rochester also are more likely to be admitted and less likely to be completely immunized against Hib (61%) than those living in suburban areas (82%). CONCLUSIONS: Although Hib vaccine has had a major impact on hospital admissions for Hib-related conditions, the goal of completely eliminating Hib disease will require programs targeted at groups at high risk, such as minorities and those living in cities.

Socioeconomic variation in discretionary and mandatory hospitalization of infants: an ecologic analysis.

OBJECTIVES: To examine geographic variation in rates of infant hospitalization for diagnoses classified by type of hospitalization decision in Monroe County (Rochester), New York. METHODS: Study design was cross-sectional and ecologic. International Classification of Diseases (ICD) codes were used to categorize all 7883 hospitalizations for infants (age, <24 months) beyond the newborn period between 1985 and 1991. Postal zip codes defined socioeconomic areas as inner-city, other urban, and suburban for the population at risk. In 1990, inner-city infants included 62% black and 65% Medicaid-covered infants, whereas suburban infants included 3% black and 6% covered by Medicaid. Hospitalization rates were compared among the three socioeconomic areas. RESULTS: Overall hospitalization rate was 50.3 per 1000 child years. Admissions classified as discretionary accounted for 59% of these, followed by those classified as mandatory, 18%; sometime (congenital heart disease, cleft palate), 15%; discretionary surgery (inguinal hernia, tonsillectomy/adenoidectomy), 6%; and unlikely to need admission, 2%. A stepwise, socioeconomic gradient in hospitalization was found, with rates of 38.1, 51.3, and 82.9 per 1000 child-years, respectively, for suburban, other urban, and inner-city areas. Rates for discretionary, unlikely, and mandatory admissions followed this gradient. Using the odds for hospitalization of suburban infants as the base odds, the odds ratio for discretionary hospitalization for inner-city infants was 2.88 (95% confidence interval [CI], 2.69 to 3. 08) and that for mandatory hospitalization was 2.20 (95% CI, 1.94 to 2.49). In multiple regression analysis, low education level of mothers explained 81% of the variance in discretionary hospitalization rate. Although the per capita rate of hospital care of inner-city infants was more than twofold greater than that for suburban infants, potential for reducing this difference is suggested by the fact that discretionary admissions accounted for 78. 9% of this difference, whereas mandatory admissions accounted for 17. 7% of the difference. CONCLUSION: The hospitalization rate for inner-city infants is much greater than that for suburban infants. A substantial portion of the difference, namely that attributable to mandatory admissions, reflected higher rates of serious illness. Differences attributable to discretionary admissions may reflect higher rates of serious illness to some extent, but also appear to reflect less effective health services to a substantial degree.

Ensuring high-quality alternatives while ending pediatric inpatient care as we know it.

Child advocates recognize pediatric hospitalization as an issue of great concern because of the serious morbidity it reflects and the adverse psychosocial effects of inpatient experience on children and families. Accounting for almost 50% of child health care costs, estimated at $49.8 billion in the United States in 1987, pediatric hospitalization also represents a substantial financial burden. Studies of the variation in childhood hospitalization rates among geographic areas, however, suggest a large portion of these hospitalizations are avoidable. In individual level analysis, admitting pediatricians judged 28% of acute, general pediatric hospitalizations to be potentially avoidable had specified alternative services been available. Furthermore, evidence supports the safety of care in alternative settings for selected acute illness episodes. Hospitals share incentives for reducing inpatient services as they join managed care organizations that capitate hospital costs. At a time when health care cost reduction has become a dominant theme in industry and politics, concern seems warranted that cost considerations might prevail over quality considerations in shaping change. The concern of child advocates is heightened by the fact that costs are measured as dollars while measures of quality remain comparatively vague.

Avoidable morbidity in infants. A classification based on diagnoses in administrative databases.

OBJECTIVES: A hierarchical classification for avoidable morbidity in infants was developed based on a conceptual model for causes of morbidity. Experts rated the impact of risk factors and health services on diseases coded according to the International Classification of Diseases, 9th Revision, Classification Modification (ICD-9-CM). An etiologic framework was chosen for the classification because knowledge of etiology often suggests strategies for prevention. Causes of morbidity that cluster on the basis of similar risk factors might be avoided using similar strategies. METHODS: Diseases (346 different diagnoses) were rated by 16 general pediatricians; 12 attributes were considered, including the impact on disease occurrence and on severity of five risk factors, preventive health services, and medical treatment. Raters evaluated the impact of health services, constitutional risk factors, and environmental risk factors without regard for service site (eg, inpatient, emergency department, primary care office). Environmental risk factors categories, including family, social, and physical environments, were rated separately. The impact of health services was rated on prevention, treatment, and complications of care. RESULTS: Only ratings indicating that the impact of a risk factor category was substantial were used for the final classification of 275 diagnoses. Consistent with the multifactorial etiology of many diseases, many diagnoses had ratings indicating substantial impact of multiple risk factors. Five mutually exclusive clusters were derived from the 12 ratings based on factor analysis and recognized strategies for prevention. Ordered by level of avoidability, these clusters were termed vaccine-preventable, health-care quality indicators, environmental, environmental/constitutional, and constitutional. CONCLUSIONS: The usefulness of this classification for policy-oriented epidemiologic and health services research is grounded in the premise that prevention is the cardinal objective of child health policy. Cluster-specific hospitalization rates, ie, rates aggregated for all diagnoses falling in a cluster, might be used for allocating resources to interventions directed at environmental or health service determinants of morbidity. Widespread use of ICD-9-CM codes in hospital discharge and ambulatory databases suggests many potential applications for this classification of morbidity burden in population groups.

Composition of gestational weight gain in adolescent pregnancy.

The objective of this study was to test three hypotheses concerning age-related differences in the composition of the weight gained by pregnant adolescents. We studied the change in maternal body composition during gestation in relation to maternal age and infant birth weight in relation to change in maternal body composition in 108 consecutive, low-income, pregnant, black adolescents. Regardless of age, approximately 26% of adolescents' body weight and 38% of the weight adolescents gain during gestation is fat. A hierarchical regression analysis revealed that the rate of gestational weight gain is significant predictor of infant birth weight among younger (R2 change = 0.15, P = 0.004), but not older (R2 change = 0.01, not significant), adolescents. Among younger adolescents, the rate of fat weight gain is the best predictor of infant birth weight. Maternal age interacts with fat weight gain (but not total or lean weight gain) to predict infant birth weight (R2 change = 0.046, P = 0.022). During gestation maternal age does not have a clinically important effect on the composition of the body or weight gained by pregnant adolescents. However, maternal age interacts with the composition of the gestational weight gain to predict infant birth weight; the fat component of the weight gain is a significant predictor of infant birth weight in younger, but not older, adolescents.

Pathways of lead exposure in urban children.

A linear structural equation modeling procedure was used to explore the mechanisms and pathways for lead intake among urban children and the relative contribution of various lead sources to lead-contaminated house dust. Dust lead levels were significantly associated with children's blood lead levels, both indirectly and directly via hand lead. Both soil and paint lead contributed to dust lead levels, but paint contributed significantly more lead to house dust than soil (P < 0.001). Black race and income level both directly affected children's blood lead levels. Finally, time spent outdoors was associated with children putting soil or dirt in their mouths which was, in turn, associated with children's blood lead levels. These data indicate that mouthing behaviors are an important mechanism of exposure among urban children with low-level elevations in blood lead and that lead-based paint is a more important contributor of lead to house dust than is lead-contaminated soil.

Effect of emergency department immunizations on immunization rates and subsequent primary care visits.

BACKGROUND: The Standards for Pediatric Immunization Practices recommend the routine use of emergency department (ED) encounters for screening the immunization status of children and, if indicated, immunizing them. OBJECTIVE: To test the hypothesis that ED immunizations will improve immunization rates without decreasing subsequent primary care visits. DESIGN: A randomized controlled trial of 2 interventions. Children (aged 6-36 months) (n = 1835) were enrolled in the study in the ED; informed consent was obtained from their parents. They were randomized into 1 of 3 groups: (1) the control group (n = 614), in which no intervention was undertaken; (2) the letter group (n = 610), in which a letter to the primary care physician was written indicating the child's estimated likelihood of being underimmunized; and (3) the ED vaccination group (n = 611), in which, based on a decision rule, those likely to be underimmunized were offered immunizations in the ED. After randomization, parents were interviewed in the ED using a decision rule to estimate the likelihood of the child being underimmunized. One year after enrollment in the study, the medical records of the children at their primary care sites were reviewed to determine the immunization status of the children and primary care use patterns. SETTING: An urban ED and 54 primary care sites in Monroe County, New York. RESULTS: The mean age of the participants was 17.9 months. Medical record review-verified underimmunization rates at the time of the ED visit were 33%, 31%, and 28% for the control, letter, and ED vaccination groups, respectively. The demographic characteristics and baseline immunization rates were not different among study groups. According to the decision rule, 248 children (41%) in the ED vaccination group were likely to be underimmunized. Parents of these 248 children were offered immunizations for their children; 117 (47%) accepted, and their children were immunized (with 230 separate immunizations). One month after the ED visits, the underimmunization rates of the study groups were 31%, 28% (P = .40 compared with the control group), and 23% (P = .002). One year later, these rates were 28%, 25% (P = .20), and 25% (P = .20). No clinically meaningful differences were present at either of these times. One year after the ED visit, no differences in the rates of primary care use were found among groups. CONCLUSIONS: This study provides evidence that the immunization of children in this ED was ineffective at raising their immunization rates; primary care attendance was also unaltered. Major obstacles were as follows: (1) an inability to ascertain accurately the immunization status in the ED and (2) a high rate of parental refusal to accept immunizations in the ED. The standards should be modified to de-emphasize the ED as a routine immunization site for children with access to primary care. Efforts and resources should be directed toward strengthening the primary care system and tracking immunization status.

Use of health services by urban youth: a school-based survey to assess differences by grade level, gender, and risk behavior.

PURPOSE: The purpose of this study was: (a) to describe reported access to health care among urban youth, and (b) to compare intention to seek care and risk behaviors for youth who did and did not seek care. METHODS: A cross-sectional survey measuring knowledge, attitudes, self-efficacy, and behavioral intentions related to sexuality and use of and access to health care was administered to 3,677 urban middle and high school students in health education classes. RESULTS: A total of 13% of students reported no established health care, whereas 25% reported no care within the past 6 months. A physical examination was the most common reason for seeking care. Younger teenagers, males, and those not under care were less aware of teen clinics, thought it more difficult to access care, and had less intention to seek care within the next year (P < .001). Older students had greater knowledge and self-efficacy concerning sexual matters, were less positive about abstinence, and higher life and sex risk scores (P < .001). Females reported greater self-efficacy regarding sexual matters, were more positive about abstinence, and had lower life risk scores (P < .001). Adolescents receiving care had higher knowledge and self-efficacy scores, were more positive about condoms, had greater intention to seek care, but had higher life and sex risk scores. CONCLUSIONS: Awareness and use of health care remain low for a sizable number of at risk urban youth, especially younger and male teenagers. The school is a setting in which adolescents not under care can be reached for provision of information about health care.

Sibling adaptation to childhood cancer collaborative study: siblings' perceptions of the cancer experience.

Investigated responses of siblings (N = 254) of children with cancer to structured interviews designed to elicit thoughts and feelings about effects of cancer on self and family. Siblings indicated distress about family separations and disruptions, lack of attention, focus of family on the ill child, negative feelings in themselves and family members, cancer treatments and their effects, and fear of death. Siblings also reported becoming more compassionate, families becoming closer, and having experiences they otherwise would not have had. Age and gender differences in responses indicated distinctive perceptions of and vulnerability to the cancer experience. Older siblings were far more likely to report positive effects than younger siblings suggesting that level of maturity can moderate the stress of an ill child within the family.

Hospitalization for lower respiratory tract illness in infants: variation in rates among counties in New York State and areas within Monroe County.

OBJECTIVE: Lower respiratory tract illness (LRI) is the most common serious illness in childhood and the most common reason for hospitalization of infants beyond the neonatal period. This study assessed the potential for cost savings from reduction in hospitalization for LRI. SETTING AND SAMPLE: LRI hospitalization rates for children in the first 2 years of life (infants) were studied for the 62 counties of New York State and six socioeconomic areas within Monroe County (Rochester) for the years 1985 through 1991. DESIGN: Analysis of small area variations. RESULTS: LRI accounted for 51.2% of infant hospitalizations in New York State. The overall LRI hospitalization rate for New York's 62 counties was 27.0 per 1000 child-years and ranged, among the 18 most populous counties, from 10.7 for Monroe County to 39.3 for the Bronx. Unemployment rate was the strongest predictor of LRI hospitalization rates for counties, explaining 29% of the variance in multiple regression analysis. Within Monroe County, LRI hospitalization rates followed a geographic gradient from the inner city (22.5) to the rest of the city (12.2), and to the suburbs (7.3). Deaths from LRI were uncommon (0.36% of state LRI hospitalizations) and varied little between inner city (0.42%) and suburbs (0.51%). If LRI hospitalization rates for Monroe County suburban children prevailed for the entire state, 10,439 hospitalizations and $32,916,000 would be saved annually. CONCLUSIONS: A large portion of the increased cost of health care for children living in poverty is attributable to hospitalization for LRI in infants. Physician discretion in decision making and factors associated with socioeconomic status are probably major determinants of variation. Well-coordinated follow-up of acute illness visits, home monitoring by visiting nurses, and empirically based clinical guidelines for management of LRI might yield both substantial cost savings and better service to families.

Sibling adaptation to childhood cancer collaborative study: prevalence of sibling distress and definition of adaptation levels.

A multisite collaborative study assessed the frequency and intensity of emotional/behavioral distress in siblings of children with cancer. A sample of 254 siblings, aged 4 to 18 years, and their parents completed interviews and self-report measures 6 to 42 (average 22.5) months after diagnosis of cancer in a brother or sister. Matched controls were obtained from respondents to the Child Health Supplement of the National Health Interview Survey administered in 1988 (CHS88). Before diagnosis, the prevalence of parent-reported emotional/behavioral problems among siblings was similar to that in the general population (7.7% vs 6.3%; p = not significant). After diagnosis, prevalence rose to 18% among siblings. When siblings were grouped according to the presence or absence of problems exacerbated by and/or arising after diagnosis, four levels of adaptation, consistent with scores on the Behavior Problem Scales from the CHS88, emerged. This differentiation may help explain inconsistencies in sibling response reported previously and provides a framework for investigating factors that enhance adaptation.
