Week 1 epidemiology and harms Flashcards
what is addiction?
Broadly speaking, addiction is a persistent, compulsive dependence on a behaviour or substance despite an awareness of the associated harms to self and others. Addiction is characterised by physiological tolerance to a substance as well as the experience of withdrawal symptoms and craving (Hart & Ksir, 2013). Tolerance to a behaviour or substance occurs when the initial response cannot be achieved without increasing the exposure. Signs of withdrawal are generally the opposite of those observed when affected by the substance or behaviour and, according to Ruiz and Strain (2014)
what is the three diagnostic criteria associated with substance withdrawal?
- Development of a substance specific syndrome as a consequence of cessation of (or reduction in) substance use that has been heavy or prolonged;
- The substance-specific syndrome causes clinically significant distress or impairment in social, occupational, or other important areas of functioning; and
- The symptoms are not a result of a general medical condition and are not better accounted for by another medical or mental disorder.
What is the DSM-5 criteria for substance use disorder (SUD)? And what classifies as mind, moderate and severe?
The severity of an SUD is defined as Mild when 2-3 criteria are present, Moderate when 4-5 criteria are present, and Severe when 6 or more criteria are present (American Psychiatric Association, 2013).
- The substance is often taken in larger amounts or over a longer period than intended.
- There is a persistent desire or unsuccessful efforts to cut down or control substance use.
- A great deal of time is spent in activities necessary to obtain the substance, or recover from its effects.
- Craving, or a strong desire or urge to use the substance.
- Recurrent substance use resulting in a failure to fulfill major role obligations at work, school or home.
- Continued substance use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance.
- Important social, occupational, or recreational activities are given up or reduced because of substance use.
- Recurrent substance use in situations in which it is physically hazardous.
- Substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance.
- Tolerance, as defined by either of the following:
a. A need for markedly increased amounts of the substance to achieve intoxication or the desired effect
b. A markedly diminished effect with continued use of the same amount of the substance. - Withdrawal, as manifested by either of the following:
a. The characteristic withdrawal syndrome for the substance
b. The same (or closely related) substance is taken to relieve or avoid withdrawal symptoms.
What is the DSM-5 criteria for Gambling Disorder? and what classifies as Mild, moderate and Severe.
A. Persistent and recurrent problematic gambling behaviour leading to clinically significant impairment or distress, as indicated by the individual exhibiting four (or more) of the following in a 12-month period:
- Needs to gamble with increasing amounts of money in order to achieve the desired excitement.
- Is restless or irritable when attempting to cut down or stop gambling.
- Has made repeated unsuccessful efforts to control, cut back, or stop gambling.
- Is often preoccupied with gambling (e.g., having persistent thoughts of reliving past gambling experiences, handicapping or planning the next venture, thinking of ways to get money with which to gamble).
- Often gambles when feeling distressed (e.g., helpless, guilty, anxious, depressed).
- After losing money gambling, often returns another day to get even (“chasing” one’s losses).
- Lies to conceal the extent of involvement with gambling.
- Has jeopardized or lost a significant relationship, job, or educational or career opportunity because of gambling.
- Relies on others to provide money to relieve desperate financial situations caused by gambling.
B. The gambling behaviour is not better explained by a manic episode.
what is the diagnostic criteria for SUD using the International Classification of Disease, 10th revision (ICD-10)? what does it focus on in comparison to the DSM-5?
The focus of the ICD-10 is on harmful use or “substance use that results in actual physical or mental damage” (Lowinson et al., p561). To be diagnosed with an SUD using the ICD-10, at least three of the following criteria must be present in the previous 12 months (World Health Organization, 1992):
- A strong desire or sense of compulsion to take the substance.
- Difficulties in controlling substance-taking behaviour in terms of its onset, termination, or levels of use.
- A physiological withdrawal state when substance use has ceased or been reduced, as evidenced by: the characteristic withdrawal syndrome for the substance; or use of the same (or a closely related) substance with the intention of relieving or avoiding withdrawal symptoms.
- Evidence of tolerance, such that increased doses of the psychoactive substance are required in order to achieve effects originally produced by lower doses.
- Progressive neglect of alternative pleasures or interests because of psychoactive substance use, increased amount of time necessary to obtain or take the substance or to recover from its effects.
- Persisting with substance use despite clear evidence of overtly harmful consequences, such as harm to the liver through excessive drinking, depressive mood states consequent to heavy substance use, or substance-related impairment of cognitive functioning. Efforts should be made to determine that the user was actually, or could be expected to be, aware of the nature and extent of the harm.
what is the correct terminology for people that have addictive behaviours?
called consumers.
Not addicts anymore because it describes them as though they are just addicts.
why is alcohol different to drunks?
alcohol is apart of our history as it has had a huge impact on society and the industrial revolution It is apart our our culture, whereas drugs have not had this impact on society.
what percentage of Australians consumed alcohol in in 2016, aged 14 and over? what is the difference between men and women? what was the average age of first consumption?
In 2016, 77.5% indicated they had consumed alcohol in the previous 12 months with a greater proportion of men (79.9%) than women (75.1%) consuming (AIHW, 2017). A significant proportion of young Australians aged 12-17 years (81.2%) have not used alcohol, and the average age at which alcohol is first consumed was 16.1 years in 2016, an increase from 14.4 years in 1998.
What are some of the main findings from alcohol research? in relation to average consumption and binge drinking?
on the surface it appears like those trends are moving in a positive direction but what we have also seen is that this is very different when you talk about state-by-state, by age groups and by consumption trends. So we know, for example that much of this drop in consumption is driven by the Northern Territory, which has seen massive declines in the last five years. Similarly, even though average consumption has gone down what we are finding is that levels of binge drinking particularly in youth (ages 18-25 years) has increased.
what age group is most likely to consume levels of alcohol considered high risk?
While 15.0% of all drinkers in 2016 reported drinking at very high risk levels, this pattern of drinking is most prevalent among those aged 18 to 29 years. Specifically, 29% of drinkers aged 18-24 and 27% of those aged 25-29 had engaged in very high risk drinking at least once during 2016 (AIHW, 2017).
How is alcohol used worldwide?
it is important to note that almost half the world’s population does not drink; in 2016, 55.5% of the global population aged 15 years or older had ever consumed alcohol. There is wide variability in consumption levels across countries, however, with developed countries reporting greater consumption levels (WHO, 2018a). A minority of the total population (18.2%) engaged in monthly heavy episodic drinking. Heavy episodic drinking was more prevalent among young individuals aged 15-19 years (13.6% of all young people) and among male (29.2%) compared to female (7.2%) drinkers.
What is tobacco uses trend over time?
As shown in Table 2, tobacco use in Australia has steadily declined since 1993. In 2016, 14.9% of individuals aged 14 or older were a current smoker, while 62% of individuals surveyed reported that they had never smoked, which constitutes a statistically significant increase since 2013.
what is the tobacco trend worldwide? and what trends are there between ages, sex and countries?
The global trend in tobacco use mirrors that found in Australia. Between 2000 and 2015 the worldwide prevalence of daily tobacco smoking has decreased (see Figure 4 below). Rates of tobacco use differ across age groups, sex, and countries. Tobacco use is higher among men than women, and in developing compared to developed countries. Countries with the highest prevalence of daily smoking in 2016 included Indonesia, Timor-Leste, Russia and Tunisia for men, and Montenegro and Serbia for women (WHO, 2018b).
what is Australia’s drug use trends and statistics in 2016? what are the sex differences? as what is the most commonly used illicit drug?
The proportion of Australians reporting use of illicit drugs in the past 12 months has remained fairly stable over time. Table 3 indicates that, in 2016, 43% of individuals reported they had ever used an illicit drug. During 2016, 15.6% of individuals surveyed indicated illicit drug use in the past 12 months. Past 12 month illicit drug use was more common among males compared to females and among individuals aged 20 – 29 years compared to other age groups. Marijuana/cannabis is the most frequently used illicit drug in Australia, with 10.4% of individuals reporting use in 2016. The use of methamphetamines, hallucinogens and synthetic cannabinoids decreased from 2013 to 2016.
illicit drug usage worldwide. what did the World Drug report and Global Drug Survey find in 2017?
In 2017, an estimated 4.1-6.9% of individuals aged 15-64 worldwide had used an illicit drug in the past 12 months (UN, 2019). Table 4 below shows the global estimate of use of the six most commonly used illicit drugs. As in Australia, cannabis is the most commonly used illicit drug worldwide. Men are two to three times more likely than women to report use of an illicit drug.
what example in the US, shows how things can change over time? Drug usage.
For the last decade, there has been an epidemic of pharmaceutical opiate use. Recent law changes, however, have made it much harder to get these pharmaceutical opiates. Due to this law change, there has been an increase in the illicit heroin market, which has led a marked increase in heroin-related deaths in the US.
how/why might prescription medication be misused?
Some individuals may unintentionally misuse pharmaceutical drugs because they have received inappropriate advice or prescription from a health professional. Other individuals may, either intentionally or unintentionally, misuse prescription medicines by using a greater quantity of a drug or using a drug more frequently than has been prescribed. Other individuals may obtain and use pharmaceutical drugs which have not been prescribed.
