Abstract |
The objective of this study was to determine whether breath alcohol elimination rate varies as a function of age, gender, and drinking practice, factorially combined. Eighty-four men and 84 women drank enough alcohol to produce peak BrACs of .110g/210L for heavy and moderate drinkers and BrACs of .090g/210L for light drinkers. An Intoxilyzer 5000 was used to generate the concentration-time profiles. Mean (M) elimination rates (g/210L/h) were found to be higher for women (N=84, M=.0182, SD=.0033) than for men (N=84, M=.0149, SD=.0029), F(1, 144)=57.292, p<.001; higher for heavy drinkers (N=56, M=.0176, SD=.0038) than for light and moderate drinkers combined (N=112, M=.0160, SD=.0032), F(1, 144)=12.434, p<.01; and higher for older subjects (51-69 years, N=42, M=.0180, SD=.0038) than younger subjects (19-50 years, N=126, M=.0161, SD=.0033), F(1, 144)=14.324, p<.001. None of the two-way interactions (age×gender, age×drinking practice, gender×drinking practice) or the three-way interaction (age×gender×drinking practice) was statistically significant. Limitations of the current study and suggestions for further research are discussed. Language: en |
