Background Research indicates the development of motor co-ordination (MC) may be an
important contributing factor to positive or negative weight trajectories across childhood.
Objectives To analyse cross-sectional associations between MC and weight status in children (boys
n = 3344 – girls n = 3281), aged 6–11 years and assess overweight/obese risk across different ages.
Methods Body mass index (BMI) was calculated [body mass (kg)/height (m2)]. MC was evaluated
using the Körperkoordination Test für Kinder (KTK) and a motor quotient (MQ) was calculated.MQ
distribution data were split into tertiles. The effect of age, sex and MQ tertiles on BMI and MC was
tested with a factorial ANOVA. A logistic regression also was performed to calculate odd ratios (OR)
for being overweight/obese at each age.
Results Children with higher MQ demonstrated lower BMI levels (F(2,6224) = 222.09; P < 0.001).
Differences in BMI among MQ tertiles became larger across age (F(10,6224) = 4.53; P < 0.001). The OR
of being overweight/obese in both sexes within the lowest MQ tertile increased in each age group
from 6 to 11 years. Specifically, OR increased from 2.26 to 27.77 and from 1.87 to 6.81 in boys and
girls respectively.
Conclusions Children with low levels of MC have a higher risk of being overweight/obese and this
risk increases with age.
