Quantifying the effects of body mass index on safety: reliability of a video coding procedure and utility of a rhythmic walking task. Objectives: To evaluate the association between body mass index (BMI) and motor actions related to safety risks (primary aim), and to examine the reliability of a video coding procedure and the utility of a rhythmic walking task in identifying safety risks (secondary aims). Design: Using a cross-sectional design, participants were filmed during a rhythmic walking task at slow, normal, and fast audio metronome paces. A video coding procedure was used to quantify signs of safety risks from the videotaped sessions. Setting: Motor development laboratory in a university. Participants: Adults (N=32) with normal (n=15) and overweight (n=17) BMI scores participated. Interventions: Not applicable. Main Outcome Measures: Chi-squared analyses were conducted to compare the occurrence of coded motor actions (forward and lateral tripping) between participants with normal and overweight BMI scores. A kappa coefficient was computed as a measure of interrater reliability on the video codes. Results: Participants who were overweight exhibited more safety risks compared with participants with normal BMI scores at the slow (χ2 1,N=32=3.94, P<.05, d=.75) and fast (χ2 1,N=32=3.85, P<.05, d=.74) metronome paces. Interrater reliability was high (κ=.90, P<.01). Conclusions: In support of the primary aim, the findings show a relationship between overweight BMI scores and safety risks. Toward the secondary aims, the results demonstrate that a video coding procedure can be reliably used to assess safety risks and that creating tasks appropriate for assessing safety risks in overweight adults is needed. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
