Blood Alcohol Content (BAC) can be affected by which factors?

Blood Alcohol Content (BAC) can indeed be influenced by several factors, and one of the most significant includes a person's body weight, gender, and the time interval between consuming drinks. Body weight plays a critical role because individuals with higher body mass generally have a higher volume of water in their bodies, which can dilute alcohol, resulting in a lower BAC.

Gender also matters because women typically have a higher percentage of body fat and a lower percentage of water than men, which can lead to higher BAC levels after consuming the same amount of alcohol. Additionally, the time between drinks affects BAC; consuming multiple drinks in a short period can cause BAC to rise more quickly, while spacing drinks out allows the body more time to metabolize the alcohol.

While age and the type of beverage can have some impact, they are not as directly associated with BAC changes as the mentioned factors. Age may affect how one’s body processes alcohol over time, and the beverage type (due to different alcohol content levels) can vary the effect on BAC, but these are not primary influencers compared to body weight, gender, and drinking pace. Therefore, the choice that encompasses body weight, gender, and time between drinks provides a more comprehensive understanding of how BAC is affected.
