title: Screen Time at Home and School among Low-Income Children Attending Head Start.
abstract: OBJECTIVE
  To describe the patterns of screen viewing at home and school among low-income preschool-aged children attending Head Start and identify factors associated with high home screen time in this population. Few studies have examined both home and classroom screen time, or included computer use as a component of screen viewing.
  
  
  METHODS
  Participants were 2221 low-income preschool-aged children in the United States studied in the Head Start Family and Child Experiences Survey (FACES) in spring 2007. For 5 categories of screen viewing (television, video/DVD, video games, computer games, other computer use), we assessed children's typical weekday home (parent-reported) and classroom (teacher-reported) screen viewing in relation to having a television in the child's bedroom and sociodemographic factors.
  
  
  RESULTS
  Over half of children (55.7%) had a television in their bedroom, and 12.5% had high home screen time (>4 hours/weekday). Television was the most common category of home screen time, but 56.6% of children had access to a computer at home and 37.5% had used it on the last typical weekday. After adjusting for sociodemographic characteristics, children with a television in their bedroom were more likely to have high home screen time [odds ratio=2.57 (95% confidence interval: 1.80-3.68)]. Classroom screen time consisted almost entirely of computer use; 49.4% of children used a classroom computer for ≥1 hour/week, and 14.2% played computer games at school ≥5 hours/week.
  
  
  CONCLUSIONS
  In 2007, one in eight low-income children attending Head Start had >4 hours/weekday of home screen time, which was associated with having a television in the bedroom. In the Head Start classroom, television and video viewing were uncommon but computer use was common.
