Waist-to-height ratio centiles by age and sex for Japanese children based on the 1978-1981 cross-sectional national survey data.

OBJECTIVES: To construct waist-to-height ratio (WC/Ht) reference values and centile curves for Japanese children and to compare these references with those from other countries. METHODS: The 1978-1981 national survey data were used for reference and the 1992-1994 national survey data were used for validation. The former included 19 233 children, and the latter included 10 446 children, aged 6 to 18 years. Waist circumferences (WC) were measured at the level of maximum waist narrowing in girls, and at the level of the top of the iliac crest in boys. Age- and sex-specific reference curves were fitted with the LMS method. Cut-off points were arbitrarily set at 85th, 90th, 95th and 97th centiles, and compared with WC/Ht 0.50. RESULTS: The proportion of children in whom WC/Ht exceeded 0.50 was 18.7% of boys and 1.9% of girls, whereas the proportion of children exceeding 90th centile was 42.4% for boys and 17.3% for girls. The reference values decreased with age in girls but varied by age without a clear trend in boys. CONCLUSIONS: The first reference values for WC/Ht are provided for Japanese youth based on the 1978-1981 national survey data. These curves are age- and sex-dependent, precluding the use of universal cut-off for WC/Ht of 0.50.

Promoting education, mentorship, and support for pediatric research.

Pediatricians have an important role to play in the advancement of child health research and should be encouraged and supported to pursue research activities. Education and training in child health research should be part of every level of pediatric training. Continuing education and access to research advisors should be available to practitioners and academic faculty. Recommendations to promote additional research education and support at all levels of pediatric training, from premedical to continuing medical education, as well as suggestions for means to increase support and mentorship for research activities, are outlined in this statement.

Principles of patient safety in pediatrics.

The American Academy of Pediatrics and its members are committed to improving the health care system to provide the best and safest health care for infants, children, adolescents, and young adults. In response to a 1999 Institute of Medicine report on building a safer health system, a set of principles was established to guide the profession in designing a health care system that maximizes quality of care and minimizes medical errors through identification and resolution. This set of principles provides direction on setting up processes to identify and learn from errors, developing performance standards and expectations for safety, and promoting leadership and knowledge.

Body temperature of newborns: what is normal?

Medical records of 203 healthy full-term infants were reviewed to determine the range of axillary temperatures for newborn infants, factors that affect temperature and nursery management of infants with temperatures outside published normal ranges. The mean birth temperature was 36.5 degrees C (S.D. = 0.6 degrees C). Temperature was associated with birth weight (p<0.0005) and the presence of maternal fever (p<0.0001) but not with type of environment or time of birth. The mean temperature increased with age, rising 0.2 degrees C by 2-3 hours after birth (p<0.0001) and 0.3 degrees C by 15-20 hours (p<0.0001). Among a subset of 114 eligible neonates the mean temperature dropped 0.2 degrees C after bathing (p<0.0001). Although 17% of all temperatures measured were in the hypothermic (< or =36.3 degrees C) range, the only response recorded by nursery staff consisted of warming by modifying the environment, e.g., bundling. Blood cultures were drawn from 51 infants (25%), 43 because of maternal intrapartum antibiotic treatment for maternal fever or prolonged duration of ruptured amniotic membranes (>24 hours) and none for evaluation of abnormal temperatures. No infants had systemic infections and all were discharged in stable condition. Newborn axillary temperatures in our nursery were considerably lower than what has been previously described as "normal." Given the frequency of "hypothermia" and absence of associated illness, we believe the reference range for newborn temperatures should be expanded to include lower temperatures.

Regional differences in infant immunization against hepatitis B: did intervention work?

OBJECTIVE: The impact of a community intervention to establish hospital nursery policies for universal newborn immunization against hepatitis B was determined by comparing primary care physician immunization practices in two counties, one intervention and one control. METHODS: Surveys were mailed to 855 physicians in 1994; 322 of 533 respondents were eligible, with 155 from San Francisco (SF), the intervention county, and 167 from Sacramento (SAC), the control county. Adoption of universal hepatitis B immunization was defined as immunizing more than 90% of infants seen in 1993. RESULTS: Although similar proportions of physicians agreed, 79% in SF and 72% in SAC, 64% of SF physicians and 40% of SAC physicians adopted universal infant immunization (P < 0.0001). Universal immunization was greater for pediatricians than for family physicians (OR = 2.00, 95% CI 1.66-2.41) but less for physicians who perceived their patients population to be at low risk for hepatitis B compared to those who did not (OR = 0.60, 95% CI 0.45-0.79). While 94% of physicians in both counties indicated their willingness to provide the second and third doses of the hepatitis B vaccine if the first dose had been administered in the newborn nursery, 64% of SF in contrast to 30% of SAC physicians reported routine nursery administration of the vaccine (P < 0.0001). CONCLUSIONS: Primary care physician adoption of universal hepatitis B infant immunization and routine nursery administration of the first dose of the vaccine were both greater in San Francisco than in Sacramento, suggesting impact of a community intervention to increase hepatitis B immunization rates.

Relationship between reason for placement and medical findings among children in foster care.

OBJECTIVE: To determine the reasons for placement of children in foster care, the prevalence of medical findings during initial placement, and the relationship between reason for placement and medical findings. The association between placement reasons and parental substance abuse also was explored. METHODS: Population-based analysis of medical records of 749 children examined at the Child Protection Center in San Francisco from October 1, 1991, to December 31, 1992. Health evaluations consisted of a clearance examination of children during entry into foster care and a comprehensive examination 3 weeks later. Reasons for foster placement included abandonment, neglect, no available caretaker, physical abuse, sexual abuse, and failed placement. RESULTS: Nearly 50% of children in our study were < 6 years of age. Neglect (30%), physical abuse (25%), and no available caretaker (24%) were the most frequent placement reasons, followed by abandonment (9%), failed placement (7%), and sexual abuse (5%). Substance abuse was documented in 30% of parents, 51% when the placement reason was neglect. Medical findings were identified in 60% of children. Among 0 to 6-year-olds, 27% had upper respiratory illnesses, 23% had developmental delay, and 21% had skin conditions; for children 7 to 12 years of age, 32% failed vision screening, 12% had dental caries, and 11% had upper respiratory illnesses; and among 13- to 18-year-olds, 31% failed vision screening and 12% had positive tuberculin skin tests. For younger children, skin conditions were associated with neglect, no available care taker, and failed placement, and developmental delay with neglect and abandonment. For adolescents, history of psychiatric illness was associated with neglect and failed placement. Marks of abuse for all age groups were limited to children who had been physically abused. Three or more diagnoses were identified for approximately 20% of children who had been neglected or abandoned or had failed placement, compared with 10% of children who had been either physically or sexually abused. CONCLUSIONS: Specific medical findings associated with reasons for placement provide health professionals with additional information to assess more accurately the health care needs of children entering foster care. As important, screening tests revealed high rates of vision problems and exposures to tuberculosis, warranting earlier and more comprehensive screening. Finally, children who have endured variations of neglect or failed placement may have more health problems than anticipated previously.

Insights into medical students' career choices based on third- and fourth-year students' focus-group discussions.

PURPOSE: To identify previously unrecognized factors influencing medical students' career choices and to better characterize the effects of educational experiences, role models, and educational debt on career decisions. METHOD: Fifty-two third- and fourth-year students were recruited from three California medical schools to participate in focus-group discussions. The students were assembled into 12 groups of about four classmates from the same school, each facilitated by a medical student from another school. Focus-group discussions were audiotaped and qualitatively analyzed using content analysis. RESULTS: The students' perceptions of their abilities to influence patients' outcomes and to cope with a large knowledge base differentiated those interested in primary care fields from those attracted to procedure-oriented specialties. Negative role models, based on the students' assessments of interpersonal interactions and career satisfaction, were particularly influential in closing doors to certain fields. Many of the women reported an absence of role models. Most of the students denied any effect of debt or potential income on career choice; while many cited their small debts, some of the women alluded to the anticipation of being in dual-income families. CONCLUSION: Students' career decisions are complex, dynamic, and individualized processes. The use of qualitative measures helps bolster understanding of these processes by identifying new factors (such as mastery of knowledge) and by further characterizing known factors (such as role models and financial considerations). A comprehensive and valid understanding of students' career-decision making is necessary to develop successful strategies to sustain and encourage the choice of primary care careers.

Gender differences in physician-patient communication. Evidence from pediatric visits.

OBJECTIVE: To determine whether physician gender and patient gender influence the process of communication and parent and child satisfaction during pediatric office visits. DESIGN: Content analysis of videotaped pediatric office visits. SETTING: University-based pediatric primary care practice. SUBJECTS: Videotaped communication between 212 children, ages 4 to 14 years, parents, and physicians. Thirty-eight percent were child health supervision visits, and 62% were for the management of minor or chronic illnesses. MAIN OUTCOME MEASURES: An established coding system of physician-patient communication and measures of parent and child satisfaction with medical care. RESULTS: Female physician visits were 29% longer than those of male physicians (P < .001). Compared with male physicians, female physicians engaged in more social exchange (P < .01), more encouragement and reassurance (P < .01), more communication during the physical examination (P < .05), and more information gathering (P < .01) with children. Male and female physicians engaged in similar amounts of discussions regarding illness management. Children were more satisfied with physicians of the same gender (P < .05), while parents were more satisfied with female physicians (P < .05). CONCLUSIONS: Children communicate more with female than with male physicians and show preferences for physicians of the same gender. These findings are consistent with communication patterns in adult patients and may have a significant influence on gender disparities in health care. Efforts at improving the process and outcome of medical care should address gender differences.

Children in foster care in the state of Washington. Health care utilization and expenditures.

OBJECTIVE: To determine and compare health care utilization and expenditures of children in foster care with those of other children and to identify and describe high-cost children in foster care. DESIGN: Analysis of the Medicaid program claims data in the state of Washington. POPULATION: A total of 1631 children in foster care and 5316 children in the Aid to Families With Dependent Children (AFDC) program in 1990. The children were ages 0 through 7 years and eligible for Medicaid continuously during the study year. MAIN OUTCOME MEASURES: Health care utilization and expenditures classified by types of health service and health care provider; proportion of children with 1990 expenditures exceeding $10,000 and most prominent diagnoses associated with their health care utilization. RESULTS: Mental health services were used by 25% of children in foster care compared with 3% of AFDC children (P < .001), and supportive services of visiting nurses and physical therapists were used by 13% of children in foster care and 1% of AFDC children (P < .001). Twice as many children in foster care than AFDC children used medical equipment or specialist services or were hospitalized (P < .001). Mean health care expenditures in 1990 were $3075 for children in foster care and $543 for AFDC children (P < .001). High-cost children included 8% of children in foster care and 0.4% of AFDC children. Among the high-cost children in foster care (n = 106), 59% had mental disorders and 31% had congenital conditions. CONCLUSIONS: Results suggest a higher prevalence and greater complexity of illnesses, particularly mental disorders, among children in foster care. Despite the high utilization and cost of mental health services, previous research suggests there may be underutilization of these services compared with need. Appropriate allocation of resources is essential if foster care agencies are to adequately meet the diverse and compelling needs of children in foster care.

Admission, recruitment, and retention: finding and keeping the generalist-oriented student. SGIM Task Force on Career Choice in Primary Care and Internal Medicine.

As the country strives to produce larger numbers of generalist physicians, considerable controversy has arisen over whether or not generalist applicants can be identified, recruited, and influenced to keep a generalist-oriented commitment throughout medical training. The authors present new and existing data to show that: 1) preadmission (BA/MD or post-baccalaureate) programs can help to identify generalist-oriented students; 2) characteristics determined at admission to medical school are predictive of future generalist career choice; 3) current inpatient-oriented training programs strongly push students away from a primary care career; 4) women are more likely than men to choose generalist careers, primarily because of those careers' interpersonal orientation; and 5) residency training programs are able to select applicants likely to become generalists. Therefore, to produce more generalists, attempts should be made to encourage generalist-oriented students to enter medical schools and to revise curricula to focus on outpatient settings in which students can establish effective and satisfying relationships with patients. These strategies are most likely to be successful if enacted within the context of governmental and medical school-based changes that allow for more reimbursement and respect for the generalist disciplines.
