OBJECTIVES.: To determine a set of perinatal characteristics that predict school difficulties in inner-city children by comparing first graders requiring remediation with first graders progressing normally. METHODS.: In a case-control study, maternal surveys about perinatal characteristics were completed for 74 of 90 remedial pre-first and 62 of 90 randomly selected first graders in the Rochester, NY, City School District. RESULTS.: Pre-first graders, as compared with first graders, were more likely to have had birth weights <2,500 g (27% versus 6%). During pregnancy, their mothers were more likely to have been unemployed (73% versus 50%), to have received WIC (68% versus 50%), to have been covered by Medicaid (58% versus 37%), and to have received late or no prenatal care (9% versus 2%). Of these factors, only low birth weight was independently associated with remedial kindergarten placement. CONCLUSION.: Potential risk factors, unfortunately, were fairly prevalent in both groups of inner-city children. While the remedial group was shown to be at greater risk, these findings have little utility in identifying subsets most likely to require remediation at school entry. Because resources aimed at preventing the long-term consequences of early school failure are limited, better means of identifying educational risk at an early age are urgently needed.

The Rochester, New York community has undergone major changes over the past 20 years. Like many other industrial areas, it has seen an erosion of its manufacturing base and a flight of employment opportunities and population from the city to the suburbs. While commonly misperceived as an affluent, white-collar community, in reality there are many families, particularly within the city of Rochester, that are afflicted by some of the most devastating health and social problems facing the United States today.(1) It was against this backdrop that, in 1991, an ongoing effort was begun to develop a system of coordinated health and human services to more effectively address the needs of Rochester's children and families. As a first step, a study was conducted to obtain a detailed picture of the current service system in Rochester; lay out a series of recommendations to improve collaboration and communication; and foster coordinated and integrated services for high-risk youth and families in the community. Key indicators of child and family health were collected, collated, and analyzed, and extensive interviews were conducted with humanservice and medical providers, government officials, education professionals, and parents. This paper describes the process that was used in the study and the recommendations that were included in the final report, which is intended to create a framework for the creation of a comprehensive, needs-based health care system for impoverished and at-risk children and families, including the effective integration of health services into the human service network.

To be consistent with national health goals and ACOG policies and recommendations, physicians providing prenatal care should encourage breast-feeding whenever possible. The parents' choice to breast- or formula-feed their infant is the consequence of a complex decision. The physician's role is to provide information objectively so that the parents' decision can be made on an informed and factual basis. Clearly, the physician must support parents' decisions. However, the distribution of formula or vouchers in the physician's office during the antepartum period places the physician in the position of advertising or promoting a specific product and of potentially contributing to the failure of some patients to nurse their infants. We urge physicians not to distribute formula or formula vouchers to their pregnant patients, and encourage local and national obstetrics organizations to consider devising and discussing a policy statement discouraging such practices

OBJECTIVE--To test the hypothesis that a reduction of 1000 ppm or more of lead in soil accessible to children would result in a decrease of at least 0.14 mumol/L (3 micrograms/dL) in blood lead levels. SETTING--Urban neighborhoods with a high incidence of childhood lead poisoning and high soil lead levels. DESIGN--Randomized controlled trial of the effects of lead-contaminated soil abatement on blood lead levels of children followed up for approximately 1 year after the intervention. PATIENTS--A total of 152 children less than 4 years of age with venous blood lead levels of 0.34 to 1.16 mumol/L (7 to 24 micrograms/dL). Children were largely poor and had a mean age at baseline of 32 months, a mean blood lead level of 0.60 mumol/L (12.5 micrograms/dL), and a median surface soil lead level of 2075 ppm. INTERVENTIONS--Children were randomized to one of three groups: the study group, whose homes received soil and interior dust abatement and loose paint removal; comparison group A, whose homes received interior dust abatement and loose paint removal; and comparison group B, whose homes received only interior loose paint removal. MAIN OUTCOME MEASURES--Change in children's blood lead levels from preabatement levels to levels approximately 6 and 11 months after abatement. RESULTS--The mean decline in blood lead level between preabatement and 11 months after abatement was 0.12 mumol/L (2.44 micrograms/dL) in the study group (P = .001), 0.04 mumol/L (0.91 microgram/dL) in group A (P = .04), and 0.02 mumol/L (0.52 microgram/mL) in group B (P = .31). The mean blood lead level of the study group declined 0.07 mumol/L (1.53 micrograms/dL) more than that of group A (95% confidence interval [CI], -0.14 to -0.01 mumol/L [-2.87 to -0.19 micrograms/dL]) and 0.09 mumol/L (1.92 micrograms/dL) more than group B (95% CI, -0.16 to -0.03 mumol/L [-3.28 to -0.56 micrograms/dL]). When adjusted for preabatement lead level, the 11-month mean blood lead level was 0.06 mumol/L (1.28 micrograms/dL) lower in the study group as compared with group A (P = .02) and 0.07 mumol/L (1.49 micrograms/dL) lower than in group B (P = .01). The magnitude of the decline independently associated with soil abatement ranged from 0.04 to 0.08 mumol/L (0.8 to 1.6 micrograms/dL) when the impact of potential confounders, such as water, dust, and paint lead levels, children's mouthing behaviors, and other characteristics, was controlled for. CONCLUSIONS--These results demonstrate that lead-contaminated soil contributes to the lead burden of urban children and that abatement of lead-contaminated soil around homes results in a modest decline in blood lead levels. The magnitude of reduction in blood lead level observed, however, suggests that lead-contaminated soil abatement is not likely to be a useful clinical intervention for the majority of urban children in the United States with low-level lead exposure

The need for a widely applicable definition of chronic conditions for research, policy, and program development has led to an extensive review of the development of such definitions, the considerations involved in their use, and some recommendations for a new approach. This paper examines some of the methodologic and conceptual issues related to defining and classifying chronic conditions and describes some consequences resulting from decisions made about these issues. While most examples are taken from child health applications, the basic concepts apply to all age groups. The dominant method for identifying and classifying children as having a chronic condition has relied on the presence of an individual health condition of lengthy duration. This condition-specific or 'categorical' approach has increasingly seemed neither pragmatically nor conceptually sound. Thus, the development of a 'generic' approach, which focuses on elements that are shared by many conditions, children, and families, is recommended. Such a definition might reflect the child's functional status or ongoing use of medical services over a specified time period. In addition, it is suggested that conditions be classified based on the experience of individual children, thus emphasizing the tremendous variability in expression of seemingly similar conditions
