Alcohol use disorder (AUD) is a medical condition characterised by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD is a brain disorder that can be mild, moderate, or severe. While no single factor or group of factors will determine whether someone becomes an alcoholic, there are several factors that increase the likelihood of alcohol abuse. These include age, gender, genetics, mental health conditions, personality, drinking patterns, and cultural and social factors.
| Characteristics | Values |
|---|---|
| Age | Alcohol use tends to begin in the late teens or early twenties, peak in the middle and late twenties, and slow by the early thirties. Individuals in their early to mid-twenties are the most likely to abuse alcohol and suffer from alcohol use disorders. |
| Gender | Males had higher rates than females for all measures of drinking in the past month: any alcohol use, binge drinking, and heavy alcohol use. However, women are at greater risk than men for alcohol-related health problems, including liver disease, cardiovascular diseases, and certain cancers. |
| Sexual minority status | The likelihood of heavy drinking or AUD is substantially greater among women who are sexual minorities than among heterosexual women. |
| Genetics and family history | About 50% to 60% of the vulnerability to AUD is inherited. Studies show people with a family history of alcohol use disorder have an increased risk of developing it. |
| Psychiatric disorders | Women who have alcohol-use disorders often have a co-occurring psychiatric diagnosis such as major depression, anxiety, panic disorder, bulimia, post-traumatic stress disorder (PTSD), or borderline personality disorder. Men with alcohol-use disorders more often have a co-occurring diagnosis of narcissistic or antisocial personality disorder, bipolar disorder, schizophrenia, impulse disorders, or attention deficit/hyperactivity disorder (ADHD). |
| Religion | Individuals who are strict adherents to religions that strongly oppose alcohol are less likely to become alcoholics. |
| Education | The more highly educated an individual is, the more likely they are to consume alcohol. |
| Personality | Individuals who are more likely to pursue or disregard risk are more likely to engage in heavy drinking; those who are less inhibited may drink more. |
| Drinking patterns | Drinking at an early age increases the risk of AUD. |

What You'll Learn
Young adults
Peer pressure and social norms also contribute to alcohol abuse among young adults. The perception of alcohol as a harmless social lubricant is pervasive, with many teens observing their parents and other adults consuming beer or wine casually. This normalization of alcohol use, coupled with effective advertising that portrays drinking as glamorous and enjoyable, creates an environment where young adults are more inclined to experiment with alcohol. Additionally, young adults who attend college have more opportunities for high-volume drinking and may delay assuming adult responsibilities, making them more susceptible to alcohol abuse.
Mental health conditions are another critical factor influencing alcohol abuse in young adults. Depression, post-traumatic stress disorder (PTSD), and attention-deficit/hyperactivity disorder (ADHD) have all been linked to an increased risk of developing AUD. Young adults struggling with these mental health issues may turn to alcohol as a coping mechanism, exacerbating their relationship with alcohol.
Furthermore, the unique brain development stage that young adults are in makes them more susceptible to the addictive nature of alcohol. The prefrontal cortex, which is responsible for impulse control and decision-making, is still maturing during this period. As a result, young adults may be less equipped to make rational choices about alcohol consumption and more prone to the addictive qualities of alcohol.
Finally, young adulthood is a time of significant life transitions and increased independence, which can bring added stress and pressure. Some young adults may turn to alcohol as a means of coping with these new challenges, leading to alcohol abuse and potentially the development of AUD. It is important to note that early intervention and treatment options, such as behavioral therapy, medication, and support groups, are available for young adults struggling with alcohol abuse to help prevent the establishment of a long-term disorder.

Women
Although the number of men with alcohol use disorder (AUD) exceeds the number of women with the same disorder, research indicates that women may be narrowing the gap. Alcohol misuse, which includes binge drinking and heavy drinking, increases the risk of harmful consequences, including AUD. Binge drinking is defined as a pattern of drinking that brings blood alcohol concentration (BAC) to 0.08% or more. While alcohol affects everyone differently, it affects women sooner and in smaller amounts because, on average, women weigh less than men.
Among women who drink, approximately one in four has engaged in binge drinking in the past month, averaging about three binge-drinking episodes per month and five drinks per episode. Research suggests that women view alcohol as a pleasurable and important aspect of their social lives. This is especially true for younger women, who share photos of cocktails, drinking, and parties on social media. A study by the Centers for Disease Control and Prevention shows that one in ten women in the United States reported symptoms of major depression in the year before the study. Another study linked women with major depressive episodes and/or anxiety disorders with a higher prevalence of substance use, including alcohol.

Genetics
The genes involved in AUD can be categorized into two main groups. The first group influences how the central nervous system responds to alcohol, impacting the brain's modification over time, similar to drug abuse. This modification can make drinking more pleasurable and tolerable, or even provide pain relief, which may motivate some people to continue drinking. The second group of genes affects how the body metabolizes alcohol, with issues in alcohol metabolism leading to alcohol intolerance, commonly seen in individuals of Asian descent.
Researchers have identified several specific genes that are candidates for being inheritable addiction genes, including ADH1B, CHNR5, GCKR, and DRD2. These genes have been found to influence neuronal plasticity, pain perception, and brain communication. Indiana University researchers discovered that it is the alteration of these groups of genes, rather than a single gene defect, that is linked to AUD. This discovery sheds light on the complex interplay between multiple genes and their impact on drinking behaviors.
While genetics plays a significant role, it is essential to consider the influence of environmental factors as well. Epigenetics, the combination of genes and environment, shapes drinking habits. For example, growing up with parents who drink or encourage alcohol consumption can increase the likelihood of developing alcohol-related issues. Recognizing these environmental influences and modifying corresponding behaviors can help mitigate the inherent risks associated with genetic predispositions.
Additionally, mental health conditions, such as depression, post-traumatic stress disorder (PTSD), or attention-deficit/hyperactivity disorder (ADHD), may further increase the risk of alcohol use disorder. The interaction between genetic factors and environmental influences underscores the complexity of AUD development and the need for comprehensive prevention and treatment approaches.

Mental health
Research has found that certain mental health conditions increase the risk of alcohol use disorder (AUD). These include depression, post-traumatic stress disorder (PTSD), anxiety, attention-deficit/hyperactivity disorder (ADHD), bipolar disorder, and personality disorders. Individuals with these pre-existing conditions are more likely to develop an unhealthy relationship with alcohol. The comorbidity of psychiatric disorders and AUD is well-documented, particularly in women. Women with AUD often have co-occurring diagnoses of major depression, anxiety, panic disorder, bulimia, PTSD, or borderline personality disorder.
Childhood trauma is another risk factor for alcohol abuse. Adverse experiences during childhood can have lasting impacts on mental health and increase the likelihood of individuals turning to alcohol as a coping mechanism later in life. Additionally, the age at which an individual starts consuming alcohol is a critical factor. Drinking at an early age, especially before the age of 15, increases the risk of developing AUD in the future. This may be due to the impact of alcohol on the developing brain and the increased vulnerability to addiction during adolescence.
Genetics also plays a significant role in alcohol abuse. Heritability is estimated to account for about 50%-60% of the risk for AUD. Individuals with a family history of alcohol problems are more likely to develop similar issues themselves. However, it is important to note that genetics is just one piece of the puzzle, and the interplay between genes and environmental factors influences the development of AUD.
Finally, personality traits can also impact the likelihood of alcohol abuse. Individuals who are more impulsive, less inhibited, or prone to taking risks may be more susceptible to heavy drinking. Additionally, those who associate alcohol with positive outcomes or believe it enhances their likability or social status may be at higher risk. Social and cultural factors also come into play, with alcohol abuse being more prevalent in cultures where drinking is acceptable or encouraged.

Social and cultural factors
Social Norms and Encouragement: Alcohol abuse is more likely to occur when drinking is socially acceptable or encouraged. For example, in college or university settings, alcohol consumption is often celebrated and even dangerous forms of drinking, such as binge drinking, may be glorified. This normalisation of excessive drinking can increase the risk of developing AUD, especially when it is seen as a way to fit in or gain social acceptance.
Age and Education: An individual's age is a critical factor, with alcohol use typically beginning in the late teens or early twenties and peaking in the middle to late twenties. Younger individuals who start consuming alcohol at an early age, particularly before the age of 15, are more prone to developing alcoholism later in life. This may be due in part to the fact that the prefrontal cortex, which is responsible for impulse control and decision-making, is not fully developed until the mid-twenties. Additionally, education level plays a role, with a higher proportion of college graduates drinking compared to those without a college education.
Gender and Sexual Orientation: Gender and sexual orientation influence drinking patterns and AUD prevalence. Women who identify as sexual minorities have a higher likelihood of heavy drinking or AUD compared to heterosexual women. On the other hand, the prevalence of heavy drinking among gay men is similar to that of heterosexual men. Women with AUD also face a higher risk of alcohol-related health issues, including liver disease, cardiovascular diseases, and certain cancers.
Personality Traits: Certain personality traits increase the likelihood of alcohol abuse. Individuals who are more inclined to pursue risks, have lower inhibitions, or seek social acceptance may engage in heavier drinking. Additionally, those who perceive alcohol positively and expect beneficial effects from drinking are more susceptible to developing alcoholism.
Social Stigma and Treatment Barriers: In cultures where drinking is considered shameful or stigmatised, individuals may be reluctant to seek treatment for AUD due to the fear of being labelled as an alcoholic. This social stigma can hinder effective intervention and recovery.
Social Learning and Family Influences: An individual's social environment, particularly their family, can influence their drinking patterns. Children with parents who drink are more likely to develop AUD themselves. This intergenerational transmission of drinking behaviours may be due to a combination of genetic and environmental factors.
These social and cultural factors interact with individual genetic predispositions and psychological conditions to contribute to the complex problem of alcohol abuse and AUD. Addressing these factors is crucial for prevention and intervention strategies aimed at reducing the harmful impact of alcohol misuse.

Frequently asked questions
According to the American Medical Association, men should limit their drinking to two drinks per day, while women should limit themselves to one. Heavy drinking is defined as five or more drinks in one day or 15 or more drinks in a week for men, and four or more drinks a day or eight drinks a week for women. Alcohol use disorder is characterised by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. Symptoms include craving beverages containing alcohol, continuing to drink despite negative consequences, drinking more than intended, spending a lot of time drinking or recovering from hangovers, and repeatedly failing to meet obligations because of drinking.
There are several risk factors for alcohol use disorder, including age, genetics, family history, mental health conditions, and trauma. Individuals who start drinking at a younger age, particularly before the age of 15, are more likely to develop alcohol use disorder later in life. Genetics also play a role, with hereditability accounting for approximately 50-60% of the risk. Mental health conditions such as depression, post-traumatic stress disorder (PTSD), and attention-deficit/hyperactivity disorder (ADHD) are also associated with an increased risk of alcohol use disorder.
Alcohol use disorder affects different demographic groups in varying ways. For example, women who have alcohol use disorders often have co-occurring psychiatric diagnoses such as depression, anxiety, and PTSD. Women are also more likely to experience physical or sexual assault, abuse, and domestic violence than women in the general population. Additionally, individuals who adhere to religions that strongly oppose alcohol are less likely to become alcoholics. Social and cultural factors also play a role, with alcohol abuse being more common in cultures where drinking is acceptable or encouraged.
Alcohol use disorder can have severe negative consequences on an individual's health, social life, and occupational functioning. It can reduce life expectancy by around ten years, with the most common cause of death in alcoholics being cardiovascular complications. There is also a high rate of suicide among alcoholics, with research finding that over 50% of all suicides are associated with alcohol or drug dependence. Alcohol use disorder can also lead to social isolation and negative consequences in personal and professional relationships.
