The Frequency and Effects of Binge-Drinking Among College Students

Table 12.2


REVIEW: The Chemical Makeup Of Alcohol

Ethyl alcohol or ethanol – the intoxicating substance

Fermentation – yeast organisms break down plant sugars, yielding ethanol and carbon dioxide

Distillation – alcohol vapors from the fermented mash are collected and mixed with water

Proof – measure of percentage of alcohol, the alcohol percentage is 50 percent of the given proof

• 100 proof vodka is 50 percent alcohol by volume


Immediate Effects

The primary action of alcohol is to depress the central nervous system

Diuretic – results in fluid being drawn out of cerebrospinal fluid and leads to mitochondrial dehydration

Alcohol irritates the gastrointestinal system

Hangover

Congeners – forms of alcohol that are metabolized slower than ethanol and more toxic

Drug interactions


Long Term Effects

Effects on the nervous system Cardiovascular effects

• Antithrombotic effect Liver disease

• Alcoholic hepatitis

• Cirrhosis Cancer Irritant to gastrointestinal system Inflammation of the pancreas Block absorption of calcium Interferes with immunity


Alcohol And Pregnancy

Fetal alcohol syndrome (FAS) – alcohol consumed during the first trimester may affect organ development, alcohol consumed during the last trimester may affect CNS development

Fetal alcohol effects (FAE) – children with a history of prenatal alcohol exposure but with fewer than the full physical or behavioral symptoms of FAS


Women And Alcoholism

Trend is for women, especially college-age women to drink more heavily

Women get addicted faster with less alcohol

Women alcoholics have death rates 50 to 100 percent higher than male-alcoholics

Only 14% of women who need treatment get it


Alcoholic Beverages and Their Alcohol Equivalencies

Figure 12.2


Blood Alcohol Concentration (BAC)or Blood Alcohol Level (BAL)

BAC – is the ratio of alcohol to total blood volume

Despite individual differences, alcohol produces some general behavioral effects depending on BAC

Learned behavioral tolerance – person learns to modify their behavior to appear sober despite a high BAC

The Legal LIMIT for a person 21 and over in PA is

.08 or 8- 100th or 2/25

The LEGAL LIMIT for a person under 21 in PA is 0.00


Psychological and Physical Effects of Various Blood-Alcohol Concentration Levels

Absorption And Metabolism

Factors that influence how quickly body absorbs alcohol:

• Alcohol concentration in beverage (includes “proof” of alcohol and mixed drinks vs “regular”)

• Amount of food and non-alcoholic drinks in stomach

• Metabolism

• Age , Gender, diet, other factors

• Body Mass Index

• Mood

• Use of other drugs such as Tobacco or Marijuana


Other factors that influences BAL/BAC

• Body Weight

• Body Height

• Personal Tolerance

• Maturity level

• Speed in which a person consumes alcohol• Exercise (dangerous due to decreased motor functions)


Women And Alcohol

Different body fat composition than men

Women have half the amount of alcohol hydrogenase, the enzyme that breaks down alcohol. If a woman and a man drink the same amount of alcohol, the woman will have a BAC that is 30% higher


Alcohol Poisoning

Death from alcohol poisoning can be caused by central nervous system and respiratory depression or inhalation of vomit or fluid into the lungs

Signs of alcohol poisoning include:

• Weak, rapid pulse

• Unusual or irregular breathing pattern

• Cool, damp, pale, bluish skin

• Mental confusion

• Vomiting

• Seizures


Alcohol Abuse And Alcoholism

Alcohol abuse – interferes with work, school, or social and family relationships or entails any violation of the law

Alcoholism – when personal and health problems related to alcohol use are severe and stopping alcohol use results in withdrawal symptoms


The Causes Of Alcohol Abuse And Alcoholism

Biological and family factors

• Alcoholism is 4-5x more common among children of alcoholics

Social and cultural factors

• Social pressure

• Family attitude toward drinking


Effects Of Alcoholism On The Family

Children in alcoholic dysfunctional families generally assume at least one of the following roles:

• Family hero

• Scapegoat

• Lost child

• Mascot


Costs To Society

Half of all traffic accidents are attributable to alcohol

In 1998, alcohol related costs to society were $184.6 billion when health insurance, criminal justice costs, treatment costs, and lost productivity were factored in

Responsible for > 25% of nation’s medical costs and lost earnings

Every underage drinker costs society and average of $4,680 a year.


Alcohol

Discussion Question:

Discuss situations when you have been drinking or you know someone who was drinking and thought that you/they were in control but may have had a high blood alcohol content. Can you safely trust your own judgment?
