Children's screen time is a risk factor for obesity. To date, children's screen time has been measured using self-report. We aimed to determine the duration and nature of children's engagement with screen-based and electronic media from immediately after school until bedtime; and examined differences by sex, deprivation, and ethnicity, and season. 169 children (mean age = 12.6y, SD = 0.46; 89 girls, 80 boys) recruited from 16 randomly selected schools in Wellington, New Zealand, wore cameras for four days that photographed their surroundings automatically every 10s. Images from after school on one day were annotated using a pre-determined coding schedule for screen-based activity. Data is being analysed for mean duration of screen time, and the types of screens and electronic media, and screen-based activities the children engaged with, and compared by key socio-demographic factors and seasonality. Key findings will be reported. This is one of the first studies to objectively assess children's screen time and media use. It demonstrates that wearable cameras can assist in assessing screen time. The findings of the study will inform health promotion strategies, including education initiatives and policy development to restrict children's screen time and electronic media use.
