Gambling involves risking something of value on an event whose outcome is determined by chance, with the intent to win something else of value. It has been a part of virtually all societies throughout history, and is found in various customs and rites of passage across the globe.

While most people gamble for entertainment purposes, a small group of individuals become seriously involved and experience gambling-related problems that can have significant personal, family, social and financial consequences. Those at highest risk of gambling-related problems are lower socioeconomic groups, and young people, particularly males. Vulnerability is also higher among those who already have a preexisting mental health condition, such as depression.

Although it may not be the main focus of this article, research has shown that there are positive aspects to gambling. For example, people who gamble often develop skills that can be used in a number of ways, such as pattern recognition and study of numbers. In addition, gambling can be a fun way to spend time with friends and family.

However, many people forget about the negative side of gambling. It can affect self-esteem, relationships and work performance. It can also cause stress, guilt and regret. These effects can be felt by gamblers and their significant others, as well as by those around them. In a public health approach, the negative impacts of gambling can be measured by using a health-related quality of life measure (HRQL) known as disability weights (DW). These measures are calculated on a per person basis and can be used to assess how much a health state reduces a person’s ability to function.
