TrendsThe average age when youth first try alcohol is 11 years for boys and 13 years for girls. The average age at which Americans begin drinking regularly is 15.9 years old.According to research by the National Institute on Alcohol Abuse and Alcoholism, adolescents who begin drinking before age 15 are four times more likely to develop alcohol dependence than those who begin drinking at age 21.

Parents RoleParents' drinking behavior and favorable attitudes about drinking have been positively associated with adolescents' initiating and continuing drinking. Children who were warned about alcohol by their parents and children who reported being closer to their parents were less likely to start drinking. Lack of parental support, monitoring, and communication have been significantly related to frequency of drinking, heavy drinking, and drunkenness among adolescents. Harsh, inconsistent discipline and hostility or rejection toward children have also been found to significantly predict adolescent drinking and alcohol-related problems

LESSON 2:What Alcohol Does to the Body?Brain- enters immediately-slows down activity of the CNS- person becomes disorganized and memory & concentration are dulled.

Liver- changes alcohol to water, carbon dioxide, and energy (oxidation)oxidize 1/3 to of an oz. in an hourno way to speed up the process ( shower, coffee)until liver can oxidize all alcohol it circulates through all body parts.

- Blood Vessels- dilate (widen) for an increase in blood flow to the skin. Causes the body to lose warmth

Heart-1. increase in heart rate2. increase in blood pressure3. lead to arrhythmias or abnormal beatingcause scar tissue to build up in the heartincrease the risk of heart attack & stroke Kidneys1. produce more urine2. dehydrated!

Stomachfood slows down the absorption processincrease flow of gastric juices from the stomach lining-repeated high levels & irritation can cause internal bleeding.

Driving Under the InfluenceDWI- driving while intoxicated blood level exceeds legal limit. (.08)**Consequences for DWI50% of all crashes where the passenger dies the driver was intoxicated38% of all traffic deaths were alcohol relatedcould be the victim of drunk drivers**Efforts to reduce DWIs open container law inside the car tests for alcohol- blood, urine, breath- refusal is automatic suspension of license. Organization- MADD and SADD

Designated Drivers- people who chose not to drink to safely get themselves and others home.

The three leading causes of death for 15- to 24-year-olds are automobile crashes, homicides and suicides -- alcohol is a leading factor in all three

BAC- blood alcohol concentration- amount of alcohol in a persons blood.Signs can begin to appear as little as .02%

Long Term EffectsBrain Damagedecrease in brain sizedestroys brain cellsloss of memory and difficulty with problem solving.

Liver Problems1. inability to breakdown fats- build up of fat interferes with the growth of new liver cells, by blocking blood flow. reduced oxygen to cells causing cell deathCirrhosis- is a build up of scar tissue.Hepatitis inflammation or infection of liver.a. weakness, fever, and jaundiceb. can cause liver failure

Tolerance and DependenceTolerance- need to drink more and more to produce the same effects.drinks more but may not appear intoxicatedDependence- (physiologically) body develops a chemical need for alcohol.marked by tolerance and withdrawal (jumpiness, sleeplessness, sweating, tremors and hallucinations).Withdrawal symptoms become so severe, person drinks more to avoid symptoms-result tolerance increases.Synergistic effect- two or more meds are taken simultaneously.

Alcohol and PregnancyFAS (Fetal Alcohol Syndrome)- leading cause of mental retardation in US- condition where fetus has been affected mentally and physically by mothers use of alcohol during pregnancy.Babys experience:low birth weightimpaired speech (clef palate)slow body growthpoor coordination

alcohol moves through the blood, passes through the placenta and umbilical cord to the blood of the unborn child.alcohol remains in the babys body longerFAS is 100% preventable

Lesson 3:Patterns of Alcohol AbuseBinge drinking- periodic excessive drinking.popular among high school and college studentsrisk of alcohol poisoning toxic condition that occurs when a person drinks a large amount of alcohol in a short period of time.Alcoholismalcoholism- physical and psychological dependence of the drug ethanol.Traits of the Alcoholicpreoccupied with alcoholafter one drink- unpredictable behavior and amount going to drink.cannot manage tension with out drinkingpersonality changes and memory lapses.

Binge DrinkingBinge drinking, often beginning around age 13, tends to increase during adolescence, peak in young adulthood (ages 18-22), then gradually decrease. Individuals who increase their binge drinking from age 18 to 24 and those who consistently binge drink at least once a week during this period may have problems attaining the goals typical of the transition from adolescence to young adulthood (e.g., marriage, educational attainment, employment, and financial independence).

Stages of Alcoholism (3 stages)Stage Onebegins with social drinking- relax, relieve stress, or depression. Begin to use to manage stress.a physical and psychological dependence develops.begins to drink and be come intoxicated regularlymakes excuses and tries to rationalize his or her drinking behavior.tolerance increasesassociated a problem drinker

Stages of Alcoholism (3 stages)Stage Tworeaches point where they cant stop drinking-physically dependentdrink everyday- craves a drink earlier and earlier in the dayexcuses for drinking and blame others for what happensdefensive behaviors are evident- denies or tries to hide the problemdrinking becomes the central event in the persons life.performance of job, at home, or school decreases. Absences become more frequent

Stages of Alcoholism (3 stages)Stage threedrinking becomes the most important thing in the persons life.problem can no longer be denied and is uncontrolled.becomes aggressive and is isolated from friends and family

A child who reaches age 21 without smoking, abusing alcohol or using drugs is virtually certain never to do so.- Joseph A. Califano, Jr., Chairman and President, The National Center on Addiction and Substance Abuse at Columbia University
