Binge drinking

Binge drinking, or heavy episodic drinking, is a modern epithet for drinking alcoholic beverages with an intention of becoming intoxicated by heavy consumption of alcohol over a short period of time, but definitions (see below) vary considerably. Binge drinking is a style of drinking that is popular in several countries worldwide, and overlaps somewhat with social drinking since it is often done in groups. The degree of intoxication, however, varies between and within various cultures that engage in this practice. A binge on alcohol can occur over hours, last up to several days, or in the event of extended abuse, even weeks. Due to the long-term effects of alcohol misuse, binge drinking is considered to be a major public health issue. Binge drinking is associated with a profound social harm, economic costs as well as increased disease burden. Binge drinking is more common in males, during adolescence and young adulthood. Heavy regular binge drinking is associated with adverse effects on neurologic, cardiac, gastrointestinal, hematologic, immune, musculoskeletal organ systems as well as increasing the risk of alcohol induced psychiatric disorders. A US-based review of the literature found that up to one-third of adolescents binge-drink, with 6% reaching the threshold of having an alcohol-related substance use disorder. Approximately one in 25 women binge-drinks during pregnancy, which can lead to fetal alcohol syndrome and fetal alcohol spectrum disorders. Binge drinking during adolescence is associated with traffic accidents and other types of accidents, violent behavior as well as suicide. The more often a child or adolescent binge drinks and the younger they are the more likely that they will develop an alcohol use disorder including alcoholism. A large number of adolescents who binge-drink also consume other psychotropic substances. Stolle, Sack and Thomasius define binge drinking as episodic excessive drinking. There is currently no worldwide consensus on how many drinks constitute a 'binge', but in the United States, the term has been described in academic research to mean consuming five or more standard drinks (male), or four or more drinks (female), over a two-hour period. In 2015, the US Centers for Disease Control and Prevention, citing the National Institute on Alcohol Abuse and Alcoholism, defines binge drinking as 'a pattern of drinking that brings a person’s blood alcohol concentration (BAC) to 0.08 grams percent or above. This typically happens when men consume five or more drinks, and when women consume four or more drinks, in about two hours.' and estimated that about 16% of American adults met these binge drinking criteria four times per month. One 2001 definition from the publication Psychology of Addictive Behavior states that five drinks for men and four drinks for women must be consumed on one occasion at least once in a two-week period for it to be classed as binge drinking. This is colloquially known as the '5/4 definition', and depending on the source, the timeframe can vary. In the United Kingdom, binge drinking is defined by one academic publication as drinking more than twice the daily limit, that is, drinking eight units or more for men or six units or more for women (roughly equivalent to five or four American standard drinks, respectively). In Australia, binge drinking is also known as risky single occasion drinking (RSOD) and can be classified by the drinking of seven or more standard drinks (by males) and five or more standard drinks (by females) within a single day. When BEACH (Bettering the Evaluation and Care of Health) conducted a study which gathered information of people over the age of 18, it defined binge drinkers as those who consumed six or more standard drinks on one occasion whether that be weekly or monthly. The above definitions are limited in that they do not take into account the time period over which the drinking occurs or the body mass of the person drinking. A person could be defined as a binge drinker even if he or she never becomes intoxicated. The term, however, has succeeded in drawing public awareness to the problem of excess drinking.. Other, less common definitions rely on blood alcohol concentration (BAC). For example, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines the term 'binge drinking' as a pattern of drinking that brings a person’s blood alcohol concentration (BAC) to 0.08 grams percent or above. Whatever the numerical definition used, heavy drinking or rapid consumption over a short period of time with the intention of becoming intoxicated is often implied when the term is used colloquially, since four or five drinks consumed over the course of a whole day and as an accompaniment to meals will not have the same effects as the same amount consumed over a couple of hours on an empty stomach. An alternative colloquial term for binge drinking, 'going on a bender', formerly implied a drinking spree of several days. Acute intoxication, such as binge drinking and alcoholism, are known potent risk factors for suicide. Binge drinking is also associated with an increased risk of unplanned and unprotected sex, unplanned pregnancies, and an increased risk of HIV infection. 10% of women and 19% of men have reported being assaulted as a result of alcohol. Males who drink more than 35 units of alcohol per week report being physically hurt as a result of alcohol, and 15% report physically hurting others as a result of their drinking. Almost 16% of binge drinkers report being taken advantage of sexually, and 8% report taking advantage of another person sexually as a result of alcohol within a one-year period. Heavy drinkers cause approximately 183,000 rapes and sexual assaults, 197,000 robberies, 661,000 aggravated assaults, and 1.7 million simple assaults each year. Binge drinking has been associated with high odds of divorce, spousal abuse, and poor job performance. Binge drinking can cause adverse effects on the body including effects on blood homeostasis and its circadian variation, cardiac rhythm, ischaemic heart disease, blood pressure, white blood cell activity, female reproductive hormone levels as well as adverse effects on the fetus. There is also evidence from animal studies that binge drinking causes brain damage. Binge drinking has been associated with lower abdominal pain in women. Ketoacidosis can occur in individuals who chronically abuse alcohol and have a recent history of binge drinking. Alcohol affects brain development quite significantly especially during adolescence when the brain is still developing. The main lobes that are involved in decision making and complex thought processes are undergoing their final development phase during adolescence and binge drinking can negatively stunt the growth of these frontal lobes.
