Here is a brief look: the age of drinking without alcohol, but the culture of alcohol consumption and parents are not in every country.
In 2016, alcohol purchasing premises and on-premise limitations were not in 11 and 24 countries, respectively, according to data from the World Health Organization.
On the other hand, "some countries have anti-alcohol bans, so it's not lawful for anyone to sell," said Dag Rekve, Mental Health and Absolute Substance Department, in Geneva, Switzerland.
"Far, most of the age limits are from 18 to 20, but there are 21 countries," said Rekv.
"Therefore, it is completely prohibited, no one can buy or sell at an age range of 13 to 25 years, and then there are no age-limiting countries. It's legal for anybody to sell," he said.
However, over the last few years, more attention has been paid to alcoholic drinkers, which are not necessarily for anyone who is not drinking alcohol.
Research suggests that greater economic wealth in the country, more alcohol consumption and higher prevalence of heavy drinking episodes.
Everyone who drinks is the highest and lowest
Binge or heavy episodic drinking for at least 60 grams or more of pure alcohol consumed for at least the last 30 days. Worldwide, about 16% of people under 15 years old, there are a lot of heavy breastfeeding, according to WHO.
"Ten grams of alcohol is a standard drink, nearly a beer bottle almost, a glass or standard drink," said Rekv. In the United States, the Center for Disease Control and Prevention defines a drink equal to 14 grams of pure alcohol.
In 2016, the highest percentage of young people between 15 and 19 years old, in Luxembourg, 54%, according to the WHO. Equatorial Guinea 53.7% and then Lithuania 53.2%.
The other countries did not drink more than half of adolescents in the last days of the age group during the last 30 days.
Countries between the ages of 15 and 19 years did not notice the episode of drinking in the last 30 days in Mauritania, Afghanistan, Kuwait, Libya, Pakistan, Somalia, Syria and Yemen.
"Europe is usually very high for adults and for ages 15 to 19," said Rekv. He has had a week-long heavyweight week over a fifth of the 15-year-old population, according to WHO.
However, he added that many European countries have recently seen the reduction of alcohol use, reflecting the number of absent-minded adolescents drinking.
According to BMC Public Health, a study published in October found that in England, 29% of the population aged 16 to 24 did not drink in 2015, up 18% in 2005.
A WHO report published in September, more than 15 countries in 15 countries and European regions, reported that a 15-year-old 15-year-old girl had a 2002 drink, with the highest prevalence in England, Scotland, Malta and Denmark. But for 2014, Malta had a higher prevalence than 20%.
Among the 15-year-old boys, more than 1 to 5 have published 24 different European countries and regional drinking days, with the highest prevalence in Malta, Denmark, England and Wales. For 2014, more than 20% of the nine countries and regions had the highest prevalence of Croatia, Malta and Italy, according to the report.
In the United States, the drop in teens also declined.
In the year 2018, 8.2%, 18.6% and 30.2% in the last month, respectively, were eighth, seventeenth and sixteenth, respectively, according to a Future Monitoring report issued by the Institute of Michigango University. Social research in December.
The percentage of 2013 fell by 10.2%, 25.7% and 39.2% in the eighth, seventeenth and fifth levels, respectively, according to the report.
Generally speaking, percentages of American adolescents make up percentages of those who use alcohol by 58% in 1994.
"Even though parents have a tolerance to alcohol and, in many cases, can alcoholic beverages give birth to the parties that keep their home, when it's time for teenagers to drink at home," Nora Volkow, Director of the National Institute for Drug Abuse, financed the report.
"So we have a very well-received drinking culture, but we are slowly changing. I think changes in attitudes are seeing smaller measures," he said.
How to reproduce the health of young people
Studies have been diverse, but some researchers do not drink alcohol for beneficial health, and can harm drinking body and brain, especially in young people. The essay links heavy alcohol exposure to brain impairment and cognitive deficits, including memory problems.
During adolescence, brain neurons are growing and boosting, and connections are developing to transmit more rapid information in the brain and to process more complex thoughts on the brain. Research suggests at that time that development occurs in the brain regions with motivation, impulse and dependence.
In general, excessive alcohol consumption is a risk factor for death or disability earlier than 15 to 49 years old, Rekve said.
In other words, all factors that are at risk of death or disability (tobacco use or physical inactivity) were a drinking-out in the global risk factor of this 2016 age, according to a published study in August, Lancet.
Based on data analysis of 195 countries and territories, alcohol use was 3.8% in boys and girls of this age group, up 12.2% of this age group.
"At the same time, we know that nearly 15% of the world's population are not over 15 years of age, which means that there may be many changes in the future," Rekve said in 2016, 57% of all men and women in the world had not abstained from alcohol in the past 12 months.
In September, the initiative called the WHO launched the SAFER effort to reduce the adverse effects of alcohol abuse by governments around the world.
The initiative has five strategies: enforcing and complying with alcohol-related policies, facilitating the reduction of driving reduction measures and facilitating access to interventions or facilitating alcohol treatment, by making alcohol-related restrictions and taking into account alcohol and price policy.
As the WHO says, in many parts of the world, drinking alcoholic beverages are a big part of celebrations and celebrations, but moderation remains a key factor.
