Daily physical activity in young children and their parents: A descriptive study. DISCUSSION (part 3)

The present study is one of the first to investigate relationships between PA in young children and their parents over the entire waking day. It expanded on previous reports by incorporating accelerometry for children, as well as parents, instead of relying on parental reports of children’s PA . Another strength is that we obtained and […]

Daily physical activity in young children and their parents: A descriptive study. DISCUSSION (part 1)

The main purpose of the present study was to examine daily PA in young children and their parents, and to explore the relationship between children’s and parents’ PA. Consistent with previous research, the present study found that young children spend most of their awake time in low intensity PA, and boys spent more time in MVPA […]

Daily physical activity in young children and their parents: A descriptive study. RESULTS (part 3)

Parents spent the majority of their time in light activity. On weekdays, more than 50% of mothers and fathers engaged in 30 min of daily MVPA; however, on weekends less than one-half of the mothers attained 30 min of daily MVPA. Fewer than 20% of mothers and less than one-third of fathers attained 60 min […]

Daily physical activity in young children and their parents: A descriptive study. RESULTS (part 2)

Physical activity Student’s t-tests revealed no differences in time spent in light activity or MVPA between children cared for at home and those in organized care. Children spent the majority of their time in light PA during weekdays and weekends. On weekdays, boys tended to attain more MVPA minutes than girls (t(50) = 1.68, P=0.098) […]

Daily physical activity in young children and their parents: A descriptive study. RESULTS (part 1)

A convenience sample of 54 families (54 mothers and 50 fathers) with children three to six years of age participated in this study. Most children were in full/part-time care during weekdays (Table 1). The majority of parents were well educated, and of high SES, which is characteristic of the study location. Approximately 10% of children […]

Daily physical activity in young children and their parents: A descriptive study. METHODS (part 5)

Statistical analyses Accelerometer data files were examined for sustained periods of zero activity. Data with >10 min of only zero counts were eliminated. Child-specific cut-points were used to categorize children’s PA into time spent in light activity (<1680 bouts of movement/ min) and MVPA (>1680 bouts of movement/min). These child-specific cut-points were developed using 15 […]

Daily physical activity in young children and their parents: A descriptive study. METHODS (part 4)

Accelerometers were used to measure PA (Actigraph model AM7164, Actigraph, USA). This instrument has been successfully used with young children. The sampling interval of the accelerometers was set at 1 min, so that the intervals for parents and children were equivalent. Although the use of a 1 min interval is regarded by some investigators to […]
