The Light Time-Use Diary and preschool activity patterns: Exploratory study
Year: 2007
Type: article
Abstract: AIM: To conduct an exploratory study of time-use patterns in Australian 5-year-old children, and to pilot the novel Children's Light Time-Use Diary as a potential tool for investigating relationships between children's time-use and weight status. METHODS: Subjects for the present cross-sectional study were drawn from an established longitudinal cohort and included eighty-four 5-year-old Australian children (36 males) originally recruited as infants in three local government areas of Melbourne. Children were weighed and measured, and body mass index (BMI; kg/m(2)) calculated. Over three to four complete 24-hour periods, parents completed the Children's Light Time-Use Diary to record their child's activities in 15-minute blocks and details about the context in which the activities took place, selecting from a list of predetermined options. RESULTS: The children studied were largely sedentary, with television viewing the most time-consuming activity outside sleep. Only 49% of children spent any time walking for transport or pleasure. Children spent a median of 71% of their time in activities that were likely to be physically active when outdoors, compared with 3% when indoors, but averaged only 110 minutes/day outdoors (excluding passive transport). The 11 overweight/obese children watched significantly more television than non-overweight children. CONCLUSION: The Children's Light Time-Use Diary appears to be a practical and informative tool, which may complement accelerometry as a tool relevant to future studies of the determinants of child overweight/obesity. Further validation studies and larger research trials seem warranted.
