Abstract

Background
Raw acceleration data lends itself to innovative metrics in which comparisons can be made across populations. This study examined whether the intensity gradient (IG) or average acceleration (AvAcc) was associated with body mass index (BMI) in children and adults and explored parent-child associations between time spent in physical activity intensities and BMI.

Methods
Parent-child dyads (n = 90) wore a wrist-mounted ActiGraph GT3X+ monitor for ≥ 3 valid days (i.e., ≥ 16hrs each day). Participants BMI was calculated.

Results
Girls BMI-z scores were positively associated with parent BMI and inactive time. Parent BMI was negatively associated with boys’ inactive time. Parental inactive time predicted girls BMI-z scores. The metrics were not associated with parent BMI, and no independent effects were observed between the metrics. Associations between boys IG and BMI z-score were observed. No independent effects were observed between the metrics and no significant associations were observed between boys BMI z-score and AvAcc. Girls AvAcc and IG was not associated with BMI z-score and no independent effects were observed between the metrics.

Conclusion
Findings support previous research which suggests that parent’s activity does not influence their child’s activity.
