OBJECTIVE To determine the prevalence and correlates of psychiatric disorders among preschool children in a primary care pediatric sample. METHOD In a two-stage design, 3,860 preschool children were screened; 510 received fuller evaluations. RESULTS For quantitative assessment of disorder (> or = 90th percentile), prevalence of behavior problems was(More)
Plants grown in lead contaminated soils can accumulate lead from the adherence of dust and translocation into the plant tissue. In order to evaluate the potential health hazard due to the consumption of plants grown in residential gardens contaminated by lead, a survey of the lead concentrations in a typical array of edible vegetables, fruits and herbs was(More)
This study uses geostatistical techniques to model and estimate soil lead levels in an urban, residential neighborhood. Sixty-two composite soil samples (median 1773 ppm; range 175 to 7953 ppm) in a four-block area of brick and stone homes were obtained. The spatial continuity of soil lead levels was modeled with a semi-variogram, which was then used to(More)
OBJECTIVE To examine the stability of psychiatric disorders with onset in preschool years. METHOD Five hundred ten children aged 2 through 5 years enrolled initially, with 344 participating in a third wave of data collection 42 through 48 months later. The test batteries used for diagnoses varied by child's age, but they included the Child Behavior(More)
Few studies have examined the epidemiology of preschoolers' psychopathology. This study included 796 4-year-old children recruited from schools and pediatric practices in a diverse, urban area. Psychiatric disorder was assessed by a structured interview adapted for preschool children and by questionnaire. The most common disorders were oppositional defiant(More)
OBJECTIVES To examine the extent of parental knowledge about lead poisoning and its prevention and to determine characteristics associated with accurate lead knowledge. SETTING Twenty-three pediatric practices and 1 family practice in Chicago, Ill, and its suburbs. METHODS A 24-question test regarding lead poisoning and its prevention (Chicago Lead(More)
Lead is a common environmental contaminant. Lead exposure is a preventable risk that exists in all areas of the United States. In children, lead is associated with impaired cognitive, motor, behavioral, and physical abilities. In 1991, the Centers for Disease Control and Prevention defined the blood lead level that should prompt public health actions as 10(More)
OBJECTIVE To examine the stability and change in oppositional defiant disorder (ODD) with onset among preschool children in a pediatric sample. METHOD A total of 510 children aged 2-5 years were enrolled initially in 1989-1990 (mean age 3.42 years); 280 participated in five waves of data collection over a period of 48 to 72 months (mean wave 5 age, 8.35(More)
OBJECTIVE To examine the correlates and predictors of stability and change in psychiatric disorder occurring among preschool children in a nonpsychiatric, primary care pediatric sample. METHOD Five hundred ten children aged 2 through 5 years were enrolled; 344 participated in a third wave of data collection 42 through 48 months later. Consensus diagnoses(More)
OBJECTIVE While studies of the effects of prenatal smoking on child psychopathology have found positive relationships, most studies (1) failed to control for a range of correlates of maternal smoking that could affect children's behavior; (2) have been conducted with school-age rather than younger children, so it is not clear when such problems emerge; and(More)
