Cross-section relationships with Percent Body Fat (%BF).

PA Index is the physical activity index (approximately the square root of average number of steps/day). MVPA is moderate and vigorous physical activity expressed in minutes per day. Ln Energy, Ln SUGAR, Ln CHO and Ln Fat are the logarithms of daily intakes in kilojoules of total energy, sugar, total carbohydrates and fat respectively. All relationships have been adjusted for these covariates in turn, as well as pubertal development, socioeconomic status, and the logarithm of body weight.
