  1. Alcohol: Effects on the Body andBehavior Sherri Garcia Full Circle Advertising: A Look at Teen Alcohol Use and Fetal Alcohol Syndrome CDC’s 2005 Science Ambassador Program

  2. Overview • Definitions • Statistics on teen drinking • Short- and long-term effects of alcohol • Blood alcohol levels • Introduction to fetal alcohol syndrome (FAS)

  3. “Drinker” Definitions • Binge drinking: Four or more drinks for a female and five or more drinks for a male at one sitting

  4. “Drinker” Definitions • Chronic drinking: Daily or almost daily alcohol consumption (60 drinks per month)

  5. Statistics on Teen Drinking • Monitoring the Future (MTF) reported that in 2004, nearly one in five 8th graders, more than one in three 10th graders, and nearly one in two 12th graders had a drink in the past month.

  6. Teen Statistics (cont.) From National Survey on Drug Use and Health (2003): • 10.9 million users ages 12-20 • 7.2 million “binge drinkers”

  7. Short-term Effects • Slower reaction times/reflexes • Heavy sweating • Blurry vision • Nausea and vomiting • Lowered reasoning ability

  8. Short-term Effects (cont.) • Poor motor coordination • Slower heart rate/breathing rate • Increased blood pressure • Anxiety/restlessness • Lower inhibition

  9. Short-term Effects (cont.) • Mental confusion • Memory loss • Coma • Death from respiratory arrest

  10. Long-term Effects • Nervous system • Muscles • Lungs • Liver

  11. Long-term Effects (cont.) • Sexual organs • Brain • Heart • Esophagus/stomach

  12. Studies on Teen Drinking

  13. Studies on Teen Drinking

  14. Blood Alcohol Level: What’s It All About? Blood alcohol level (BAL) depends on: • Weight • Amount of food and water in stomach • Carbonated alcoholic beverages • Gender

  15. Blood Alcohol Level Calculations BAL = (150/body weight) x (%alcohol/50) x (ounces consumed) x (0.025)

  16. Blood Alcohol Level Example • 175 pound man drinks four 12-ounce cans of beer with 4% alcohol content • BAL = (150/175) x (4/50) x (48) x (0.025) • =.86 x .08 x 48 x .025 • = .08%

  17. Blood Alcohol Levels: So What? • BAL = 0.03 to 0.12 (Euphoria) • Self-confident/daring • Short attention span • Poor judgment • Fine motor skills impaired

  18. Blood Alcohol Levels • BAL = 0.09 to 0.25 (Excitement) • Sleepy • Memory loss • Reaction time decreased • Uncoordinated/loss of balance • Blurry vision and impaired senses

  19. Blood Alcohol Levels • BAL = 0.18 to 0.30 (Confusion) • Confused/dizzy • Highly emotional • Cannot see/slurred speech • Uncoordinated/sleepy • May not feel pain as easily

  20. Blood Alcohol Levels • BAL = 0.25 to 0.40 (Stupor) • Can barely move at all • Cannot respond to stimuli • Cannot stand or walk • Vomiting • Lapse in and out of consciousness

  21. Blood Alcohol Levels • BAL = 0.35 to 0.50 (Coma) • Unconscious • Reflexes depressed • Decreased body temperature • Decreased breathing rate • Decreased heart rate • Could die

  22. Blood Alcohol Levels • BAL = Greater than 0.50 (Death) • Breathing stops • That says it all!

  23. Driving Limits • Most states set the legal level of intoxication at 0.08 to 0.10

  24. Drinking is a Personal Choice but Who Else is Affected? • Friends and family • Strangers • Unborn babies – Fetal alcohol syndrome

  25. What is Fetal Alcohol Syndrome? • When mother drinks, baby drinks • Alcohol disrupts brain development

  26. Looking Back • Drinking has various definitions • Binge and Chronic • Drinking can have short- and long-term effects • Slower reaction times • Memory loss • Nervous system/liver problems

  27. Looking Back (cont.) • Blood alcohol levels are affected by weight and gender • Drinking is a personal choice, but it can affect those around you
