Parental behavior in relation to physical activity and fitness in 9-year-old children.

Abstract: • Objective. —To examine the relationship between parental behaviors and physical activity and fitness in elementary school—aged children. Design. —Cross-sectional survey of students and parents. Setting .—Seven public elementary schools in a suburban southern California city. Participants. —One hundred forty-eight fourth-grade girls and 149 fourth-grade boys and their parents. Eighty-four percent were white. Interventions. —None. Measurements/Main Results. —Children's physical activity was indicated by self-report, data obtained from a monitor (accelerometer), and results of the mile run/walk. Multiple regression analysis, controlling for ethnicity and body mass index, was conducted separately for girls and boys to explain variation in child activity and fitness. Parents' reported physical activity was not associated with child activity or fitness. However, availability of transportation by parents to sport and fitness activities was significant (or nearly so) in two regressions for boys and in one regression for girls. Parents who played with their children had more active boys, based on self-report, but verbal encouragement to be active was not significant in any model. Conclusion. —The parental role as gatekeeper of access to activity and sport facilities deserves further study. ( AJDC . 1992;146:1383-1388)

Ecosystem Alteration by Mosquitofish (Gambusia affinis) Predation

Abstract: In artificial pools Gambusia affinis greatly reduced rotifer, crustacean, and insect populations and thus permitted extraordinary development of phytoplankton populations (2x108 cells per milliliter). Other effects included decreased optical transmissivity and increased temperature of the water, decreased amounts of dissolved inorganic phosphorus, and increased amounts of dissolved organic phosphorus, inhibition of Spirogyra, and replacement of one annelid, Chaetogaster, by another, Aeolosoma.

Developmental and behavioral needs and service use for young children in child welfare.

Abstract: Objective To determine the level of developmental and behavioral need in young children entering child welfare (CW), estimate early intervention services use, and examine variation in need and service use based on age and level of involvement with CW by using a national probability sample in the United States.
