B-32 Free Communication/Poster - Epidemiology of Physical Activity and Health in Youth Wednesday, June 1, 2016, 1: 00 PM - 6: 00 PM Room: Exhibit Hall A/B
PURPOSE:This study examined the relationships between motor skills, physical activity levels, and obesity markers in children 7-10 years of age.
METHODS:Participants (n=55) were recruited to measure their height, weight, waist circumference, motor skills, and physical activity levels. Motor skills (manual dexterity, catching and aiming, and balance) were assessed using the Movement Assessment Battery for Children 2nd edition. Motor skills were scored for each component and a total score was also obtained. Body mass index (BMI) and BMI z-scores were calculated. Participants wore an accelerometer for seven days to determine the time spent in moderate and vigorous physical activity, as determined using Evenson et al. cut-points. Correlations were used to examine the relationships between the motor skill components, physical activity levels and obesity markers. Regression analyses were utilized to examine these relationships adjusting for sex.
RESULTS: The majority of the sample was male (53%), Caucasian (71%), a healthy weight (56%), and did not meet current physical activity guidelines (63%). Neither BMI z-score nor waist circumference was related with physical activity levels. Univariate analysis indicated that balance was negatively related to BMI z-score (r=-0.27, p=0.045), and moderate physical activity (r=-0.329, p=0.029); waist circumference approached significance (r=-0.26, p=0.056); no other relationships between motor skills, obesity markers, and physical activity were found. After adjusting for sex, these relationships were no longer significant (p>0.05); however, the relationship between BMI-z score and aiming and catching approached significance (p=0.067).
CONCLUSIONS:BMI and moderate physical activity seem to have limited impact motor skill components. Further, the impact obesity markers and physical activity have on motor skills may differ between boys and girls. Additional research is needed to quantify these relationships.
