All β estimates and 95% confidence intervals are obtained from linear regression models. Confidence intervals that do not include 0 are in bold. Model 1 was adjusted for BMI Z-score, age at Tanner stage 4, and daily energy level (total kCal/day). Model 2 was adjusted for model 1 plus maternal education level, hours of daily television watching after school, dairy intake (g/day), meat intake (g/day), waist circumference, and menarche. βs represent absolute differences in outcomes in the second, third, or fourth quartile of SSB intake compared to the first (the reference category). Significant trends were evaluated by modeling the median SSB intake within quartiles as a continuous variable and presented as p values
