Multinomial regression of physical activity and cardiorespiratory fitness at age 16 years on suspected motor problems and low preference for active play at age 8 years.

aMetabolic equivalent-hours based on the intensity and volume of physical activity divided into gender-specific quintiles: 1) active (two highest quintiles), 2) moderately active (third and fourth quintiles) and 3) inactive (lowest quintile).bPeak oxygen uptake (VO2peak) in ml·kg−1·min−1 divided into gender-specific quintiles: 1) high (two highest quintiles), 2) average (third and fourth quintiles) and 3) low (lowest quintile).cAdjusted for mother's and father's socio-economic positions when the children were 7 years old and for change in body mass index from 7 to 16 years. OR, odds ratio; 95% CI, 95% confidence interval.dLow preference for active play was defined as parents reporting that children liked to participate in active play ‘hardly ever’.
