b1–regression coefficient with both the independent and dependent variables standardized as z scores; b2–regression coefficient with only the independent variable standardized as a z score; BMI indicates body mass index; HbA1c, glycated hemoglobin; HOMA‐IR‐ homeostatic model assessment for insulin resistance; and SOL Youth, Study of Latino Youth. Model 1: Adjusted for age, sex, place of birth, Hispanic background, household income, parent/caregiver education, Tanner stage, site, min/day of accelerometer wear time, number of wear days, and proportion of wear days that were weekdays. Model 2: Adjusted for the same covariates as Model 1, plus total sedentary time. Model 3: Adjusted for the same covariates as Model 2, plus moderate‐to‐vigorous physical activity.
