Figure 1 shows the survival curves for age at drinking initiation, panel “A” for males and panel “B” for females. Whites, both men and women, began drinking earlier and had higher rates than Blacks and Hispanics (men: logrank χ2 = 157.58, p < 0.001; women: logrank χ2 = 589.39, p < 0.001). There were no differences between Blacks and Hispanics.
