摘要：Physical activity, inactivity, and obesity were assessed by questionnaire among a multiethnic sample of 552 girls in grades 5 through 12. Hispanics and Asians reported lower activity levels than other racial groups. Only 36% of the entire sample and less than one fifth of either Asians or Hispanics met the year 2000 goal for strenuous physical activity. Physical activity was inversely associated with age and age-adjusted body mass index. Obesity was unrelated to inactivity.
