TABLE 3.

The relationship between early screen exposure and hyperactive behaviors (N = 42,841).

Annual exposure (yes) or non-exposure (no)	Model 1‡ OR (95% CI)	Model 2§ OR (95% CI)	Model 3¶ OR (95% CI)
Age 0–1	1.66 (1.32–2.08)***	1.51 (1.18–1.95)**	1.48 (1.15–1.91)**
Age 1–2	1.55 (1.20–2.01)**	1.24 (0.92–1.69)	1.23 (0.90–1.66)
Age 2–3	1.31 (0.92–1.87)	1.08 (0.73–1.58)	1.05 (0.71–1.55)

^‡The first model independently analyzed the association between screen exposure and hyperactive behaviors at ages 0–1, 1–2, and 2–3 years.

^§The second model included screen exposure at each age into a binomial logistic regression model to analyze the association between screen exposure at each age and hyperactive behaviors.

^¶The third model analyzed the association between screen exposure and hyperactivity at each age after adjusting for child’s sex, number of children in the family, maternal and paternal age at child’s birth, maternal and paternal education level, monthly household income, and parental marital status.

CI: Confidence intervals. **P < 0.01; ***P < 0.001.
