Associations of objectively measured MVPA with self reported Variety and Frequency

		Variety and Frequency in separate models					Variety and Frequency in the same model
Outcome	Exposure	Exp. β	95% CI		P-value	% variance explained by exposure	Exp. β	95% CI		P-value	% variance explained by exposure
MVPA	Variety	1.04	1.02	1.06	<0.001	1.18	1.01	0.98	1.04	0.402	1.36
	Frequency	1.04	1.02	1.06	<0.001	1.32	1.03	1.00	1.06	0.051

Variety and Frequency were transformed to z-scores so effect sizes are directly comparable.

Associations were tested using multilevel linear regression.

Models were adjusted for age, sex, parental education level and age standardised body mass index (BMI).

MVPA; moderate-to-vigorous physical activity was log transformed for analysis. The β coefficients and 95% confidence intervals (95% CI) were then exponentiated for interpretation. Exponentiated β (Exp. β) and 95% CI represents a ratio of geometric means and can be interpreted in the same way as odds ratios. i.e. Exp. β and 95% CI <1 equates to a negative association whereas Exp. β and 95% CI >1 equates to a positive association.

P-value for significance of the association of Variety or Frequency with physical activity.
