Factors that Affect BAC
Blood alcohol content (BAC) is a measure of the amount of alcohol that is present the blood, based on the volume of alcohol consumed over a given period of time.
Factors that affect your BAC include the following:
- Age – the older you are the harder it is for your body to efficiently process alcohol.
- Biological Sex – Males tend to produce more of the enzyme alcohol dehydrogenase which helps to process alcohol. Additionally, female-bodied people tend to have lower water content in their bodies than male-bodied people, which makes it harder for their bodies to process alcohol because it is a highly water soluble substance.
- Rate of Consumption – The longer the amount of time it takes you to consume a drink the lower your BAC will stay because you’re providing your body with enough time to process the alcohol.
- Type of drink – Stronger drinks contain more alcohol per volume, which means your body has more alcohol to process in the bloodstream.
- Emotional State – stress, fatigue, depression, etc. call all affect how efficiently your body is able to process alcohol
- Medical conditions – such as diabetes, sickness (ex. flu, respiratory infection, stomach virus, etc.), auto-immune disorders, prescription medications (including: hormones for transgender people, birth control, pain medications, personality and mood disorder medications, allergy medications, etc.), ADHD, etc. If you are taking any medications (including non-prescription), check the product labels for alcohol warnings, or consult your doctor or pharmacist before you drink.
- Food – Foods high in protein and fat reduce the rate at which alcohol is absorbed into the bloodstream, giving your body more time to process the alcohol. Remember: more time = lower BAC.
- Body Composition:
- More body weight = more water content in the body which means a better ability to process alcohol
- Muscle to Fat ratio – muscle has a higher water content than fat which means it is better able to absorb alcohol
- Metabolism – this varies between people and impacts the speed at which your body can process alcohol
Be a Blue Hen Friend: Harm Reduction Strategies
Use these sweet tips to be a Blue Hen Friend and reduce harm associated with high-risking drinking that you or your peers may experience.
- When you’re going out:
- Travel with a group of friends, keep track of your friends and don’t leave anyone behind.
- Come up with a secret code with your friends that signals if one of you needs help.
- Know where you are going and have a plan to get home safely.
- Store emergency numbers in your phone, and use the LiveSafe app to use the Safe Walk feature or to report suspicious activity, people fighting or other emergencies.
- Many UD students do not drink, but if you choose to drink:
- Know your drinking limits and stop drinking when you need to
- Remember to pace yourself. Reasonable drinking looks like 4 drinks or fewer for men and 3 drinks or fewer for women in one night. Note: these numbers can be impacted by factors such as: body composition, medical conditions and stress.
- Eat filling foods that have fats and protein and stay hydrated by alternating with non-alcoholic drinks to avoid consuming too much alcohol.
- Avoid drinks from large, open containers, as well as mixing alcohol with other substance use.
- Anytime and Always:
- Respect everyone. Remember, not everyone drinks, and a sexy outfit is not an invitation for sex.
- Set clear boundaries, and respect the boundaries of others.
- If you witness a creepy situation or someone being aggressive, create a distraction to separate the people involved, ask someone else to step in or call for help.
- Recognize the signs of an alcohol emergency (VITALS) and call 911 for help if you or a friend is experiencing even ONE sign. Remember, Amnesty is available.
VITALS: Alcohol Emergency Signs
If you see a fellow Blue Hen experiencing even ONE of these symptoms, get help immediately! You must find an RA or call 911 to qualify for Amnesty. Don’t forget, according to UD Policy, after you call for help you “must remain with and monitor the student’s condition until assistance arrives, and cooperate fully during the medical and investigative process.”
- Irregular Pulse
- Trouble Breathing
- Abnormal Skin
- Loss of consciousness
A red solo cup filled to the brim with beer as less alcohol in it than a red solo cup filled with wine. This is because alcohol content is not based on the volume of the container. As a result, we refer to the concept of a “standard drink.” Confused? Let’s break it down, one standard drink is equivalent to: 12 ounces of regular beer (or White Claw) = 10 ounces of a wine cooler (or Mike’s Hard) = 5 ounces of wine = 1.5 ounces of hard liquor.
You can use the lines on a Solo cup for an approximation of these measurements:
You can learn more about a standard drink from the National Institutes of Health’s Rethinking Drinking webpage, which is the source of the more comprehensive graphic below:
