The Relationship

The mean and standard deviation over 24 h for 3 groups of animals - active, intermediate and inactive - in physical activity units were 10948 ± 3360, 2611 ± 1973 and 484 ± 316 respectively. The differences were significant ( P = 0·004), demonstrating the ability of the method to distinguish between groups that can be visibly differentiated. The small within-animal physical activity standard deviation (18·85 PAU) obtained in another group, suggests that it also yields reliable physical activity measurements for non-human primates. The monitoring device used can discriminate between individual nonhuman primate physical activity levels in a free-living environment and does not alter daily behaviour. This makes possible the study of the relationship between physical activity and atherosclerosis in nonhuman primates.

Children’S Physical Activity

Purpose This study examined the associations of physical activity levels between parents and their pre-school children based on gender and weekday/weekend. Method A total of 247 parent-preschool child triads from Shanghai, China were analyzed. The children had a mean age of 57.5 ± 5.2 months. Both sedentary behavior and physical activity were measured in all participants using an ActiGraph GT3X+ accelerometer over seven consecutive days from Monday through the following Sunday. A multivariate regression model was derived to identify significant relationships between parental and child physical activity according to gender and weekday/weekend. Results There was a significant correlation between mothers’ and girls’ moderate-to-vigorous physical activity (MVPA) and total physical activity (TPA) on weekdays. Fathers’ MPVA levels correlated significantly with those of boys and girls, with paternal influence appearing to be stronger than maternal influence. However, there was not a significant correlation between fathers’ and children’s TPA. TPA levels of both mothers and fathers correlated with those of girls, but not with those of boys. Parental sedentary levels on the weekend correlated significantly with girls’ levels, but not with boys’ levels. Children’s physical activity levels on weekends were influenced more by fathers’ activity levels than by mothers’, while the opposite was observed on weekdays. Conclusion Sedentary behavior and physical activity levels of parents can strongly influence those of their preschool children, with maternal influence stronger during the weekdays and paternal influence stronger on the weekends. Parents’ activity levels influence girls’ levels more strongly than they influence boys’ levels.

Observation Period

Background:It is known that children are more physically active outdoors than indoors. However, few previous studies have observed the time course for physical activity as young children transition from indoor to outdoor activities.Methods:Participants were 3- to 5-year-old children enrolled in the Children’s Activity and Movement in Preschool Study (CHAMPS). Trained observers used the Observational System for Recording Physical Activity in Children-Preschool Version (OSRAC-P) to record children’s physical activity levels over 20 minutes in outdoor settings. The 20-minute outdoor observational period began immediately following the transition from indoors to outdoors.Results:Children’s activity levels were moderately high at the time of transition and declined over the 20-minute observation period. Different patterns, however, were observed for boys and girls. Overall, boys were more active than girls. Boys’ activity levels declined in a linear fashion over the 20-minute period, while girls’ activity levels increased slightly, decreased, and then increased slightly again.Conclusions:These data indicate that physical activity levels decline with increased duration of outdoor play. The frequency and duration of outdoor play should be investigated for the purpose of optimizing physical activity levels.

Physical Activity Levels

Background Promotion of increased physical activity is advocated for survivors of an intensive care unit (ICU) admission to improve physical function and health-related quality of life. Objective The primary aims of this study were: (1) to measure free-living physical activity levels and (2) to correlate the measurements with scores on a self-reported activity questionnaire. A secondary aim was to explore factors associated with physical activity levels. Design This was a prospective cohort study. Methods Nested within a larger randomized controlled trial, participants were block randomized to measure free-living physical activity levels. Included participants wore an accelerometer for 7 days during waking hours at 2 months after ICU discharge. At completion of the 7 days of monitoring, participants were interviewed using the Physical Activity Scale for the Elderly (PASE) questionnaire. Factors associated with physical activity were explored using regression analysis. Results The ICU survivors (median age=59 years, interquartile range=49–66; mean Acute Physiologic Chronic Health Evaluation [APACHE II] score=18, interquartile range=16–21) were inactive when quantitatively measured at 2 months after hospital discharge. Participants spent an average of 90% of the time inactive and only 3% of the time walking. Only 37% of the sample spent 30 minutes or more per day in the locomotion category (more than 20 steps in a row). Activity reported using the PASE questionnaire was lower than that reported in adults who were healthy. The PASE scores correlated only fairly with activity measured by steps per day. The presence of comorbidities explained one third of the variance in physical activity levels. Limitations Accelerometer overreading, patient heterogeneity, selection bias, and sample size not reached were limitations of the study. Conclusions Survivors of an ICU admission greater than 5 days demonstrated high levels of inactivity for prolonged periods at 2 months after ICU discharge, and the majority did not meet international recommendations regarding physical activity. Comorbidity appears to be a promising factor associated with activity levels.
