A survey was completed of US pediatric residency programs about the use of community sites in training. A total of 85% of program directors responded and reported a wide use of the 21 identified survey sites. Further study is needed to determine the appropriate contribution that community sites can make to pediatric training.

The use of children in research raises the questions about proper justification, assessment of benefit in relation to risk, ability to consent, compensation, and the just selection of subjects. Although substantive and procedural standards have evolved, subpopulations of vulnerable children created new challenges and concerns.

Despite the magnitude and importance of the problem, little is known about why many students are absent from school. This study assessed what a sample of excessively absent students and their parents believed were the reasons for the students' absences. In response to an open-ended question about their main reason for absence, almost half of the students reported a health-related reason. When asked whether any of 15 potential problems contributed to their absence, many reported common and acute physical illnesses, headaches or stomachaches, and other aches or pains. Half mentioned factors relating to low motivation or a concern about the school environment. The parents' responses were remarkably similar except they were more likely to cite emotional problems of the student, school violence, and racial problems. When individual student's responses were compared with those of his or her parents, agreement on individual items were little better than would be expected by chance.

Excessive school absence is a major educational and social problem in the United States, yet very little is known about its etiology or how to prevent or ameliorate it. This paper reports results from a series of related studies conducted in seven Boston middle schools (grades 6, 7, and 8) to test the hypotheses that health problems and unmet health needs are major characteristics distinguishing excessively absent students from regular attenders and that a health-oriented approach using medically mediated interventions is effective in reducing absences among excessively absent students. There were no significant differences between regular attenders and excessively absent students on multiple measures of student and family health status, health habits, and health service utilization patterns in a case-control study. The intervention program was not associated with a significant decrease in absence school-wide or for participating students. We conclude that demographic and educational characteristics of students exert a greater effect on their behavior in regard to absence from school than do health status or receipt of health services and that a health-oriented approach, such as the one used here, will not have a major impact on what remains one of the most profound educational and social problems involving children in the United States today.
Excessive school absence is a major educational and social problem in the United States which is most pronounced in urban school systems. A case control study of excessively absent inner-city middle-school students and regular attenders failed to demonstrate any differences between groups in terms of health status, health-related behaviors, or utilization of health services. These results contrast dramatically with the findings of a previous study which identified a number of educational and demographic characteristics which clearly distinguish excessively absent students from regular attenders. It is concluded that educational and demographic factors are far more important in influencing excessive absence behavior than are health-related factors. The implications of these findings for the pediatrician are discussed.
Pediatricians' success in the role of advocate can be associated with fewer injuries to children. The authors emphasize the importance of pediatrician advocacy for injury prevention, including preventive health maintenance, education, community organization, professional education, development of emergency medical services, and legislation and regulation.
The authors designed a pilot study to test if exposure to child abuse or neglect is associated with suicidal behavior in adolescence. Each of 159 adolescents who had attempted suicide was age- and sex-matched with two comparison subjects who had been treated for medical conditions unrelated to suicide attempts. The registry of the Massachusetts Department of Social Services was searched for the names of the subjects and comparison subjects. For both sexes prior contact with the Department of Social Services was three to six times more likely for probands than for the comparison subjects.
Demographic and behavioral characteristics, including use of alcohol, were investigated among 1711 women registering for prenatal care at Boston City Hospital. During personal interviews, 9% reported drinking heavily, 37% moderately, and 53% rarely or not at all. The women who drank heavily differed from the rest of the pregnant population on several traits, including age, education, use of cigarettes, marijuana and other drugs, parity, and association with others who drank heavily. Multiple regression analysis revealed that these traits had little predictive power for whether a woman was a heavy drinker. A systematic drinking history remains the most practical method in identifying problem drinkers.
It has been widely reported that adolescent mothers are more likely to experience poor pregnancy outcome, especially low-birth-weight and/or premature infants. Recent data suggest that this poor outcome may be attributed to confounding health and social characteristics of adolescent mothers. A study of maternal health and neonatal development at Boston City Hospital provided an opportunity to assess whether adolescent mothers deliver infants with poorer outcomes at birth than nonadolescents independent of numerous social and health differences between adolescent and nonadolescent mothers. A total of 275 infants of primiparous adolescents (aged 13 to 18 years) were compared at birth with 423 infants of primiparous nonadolescents. Size at birth, length of gestation, Apgar scores, and birth trauma were examined. The only statistically significant difference between the two groups was that adolescent mothers delivered infants whose mean weight was 94 g less (P less than .03) than infants of nonadolescent mothers. Multiple and logistic regression analyses demonstrated that several health and social factors, but not adolescent status, were independently associated with the measures of adverse infant outcome. A subsequent regression analysis demonstrated similarly that being a younger adolescent (16 years and younger) did not independently predict low birth weight at delivery or other measured adverse neonatal outcomes. These data support the view that health and social factors are more important to poor fetal outcome among primiparous mothers than adolescent status. Some of the health factors are amenable to clinical intervention.
A study of 1,709 mother/child pairs at Boston City Hospital examined whether maternal cigarette smoking, drinking, or the use of other psychoactive substances was associated with low infant Apgar scores. The potential confounding effects of other labor and delivery risks were controlled in the analysis. In contrast to previous reports, univariate and stepwise multiple regression analyses did not identify a significant negative association between cigarette smoking and 1- or 5-minute Apgar scores. None of the substance use variables was significantly associated with low infant Apgar scores at 1 and 5 minutes. Other labor and delivery risks, such as short length of gestation, abnormal delivery presentation, placental abnormalities, nuchal cord, and exposure to general anesthesia during delivery, were associated with low Apgar scores.
As part of a prospective study investigating maternal characteristics and habits during pregnancy and their impact on fetal development, 1,690 mother/infant pairs were studied. Of the mothers, 375 reported using Bendectin during pregnancy. Multivariate analyses examining birth weight, length, head circumference, gestational age, and congenital malformations as dependent variables demonstrated no associations between Bendectin exposure and adverse fetal outcome.
