phase or between the 3 subgroups. Figure 5 shows peak data for balance scores collapsed between the two menstrual cycle phases in each of the 3 subgroups; there were no differences between FHP light and FHP moderate drinkers at any dose. However, FHP light drinkers and FHP moderate drinkers were both less impaired than FHN women on the balance task following the high dose of alcohol (Ps<0.04), whereas only FHP moderate drinkers were less impaired than FHN women following the lower dose of alcohol (p=0.005).
