Associations between measures of adiposity and physical activity levels.

aModel A: adjusted for age.bModel B: adjusted for age, birth weight, gestational age at birth, maternal smoking during pregnancy, maternal education, parental social class, maternal BMI, stage of puberty, total daily dietary intake, and intake of main food groups.cCoefficients are displayed as sex-specific z-scores for both measures of adiposity and activity levels and have also been rescaled to give more meaningful outcomes relating to the raw units of these variables. The raw-unit difference was computed by multiplying the z-score value by the SD of the variable, taken from Table 1.dModerate-to-vigorous activity was log transformed for analysis.a模型A：针对年龄进行校正。 b模型B：针对年龄、出生体重、出生胎龄、孕期母亲吸烟状况、母亲受教育程度、父母社会阶层、母亲体质量指数（Body Mass Index, BMI）、青春期分期、每日总膳食摄入量以及主要食物类别摄入量进行校正。 c系数以性别特异性z分数（z-score）的形式呈现于体脂水平与活动水平的两项测量指标中，且已进行重新缩放，使其结果可匹配这些变量的原始单位，从而得到更具实际解读价值的结果。原始单位差值通过将z分数乘以变量的标准差（Standard Deviation, SD）计算得出，该标准差取自表1。 d中等至剧烈体力活动经对数变换后用于本次分析。
