Heavy Soda Diets Could Link to Teen Violence: Study

Researchers in the United States said on Tuesday they had found a shocking association -- if only a statistical one -- between violence by teenagers and the amount of soda they drank.

A "shocking" association -- if only a statistical one -- between violence by teenagers and the amount of soda they drank has been uncovered by researchers in the United States.

High-school students in inner-city Boston who consumed more than five cans of non-diet, fizzy soft drinks every week were between nine and 15-percent likelier to engage in an aggressive act compared with counterparts who drank less.

Teen Violence on the Rise in UK � Seven Asians Convicted for Brutal Hammering
Seven Asian teenagers have been convicted of brutally battering a schoolboy to the brink of death with a claw hammer. In another incident, a student was impaled on a goalpost.

"What we found was that there was a strong relationship between how many soft drinks that these inner-city kids consumed and how violent they were, not only in violence against peers but also violence in dating relationships, against siblings," said David Hemenway, a professor at the Harvard School of Public Health.

"It was shocking to us when we saw how clear the relationship was," he told AFP in an interview.

But he stressed that only further work would confirm -- or disprove -- the key question whether higher consumption of sweet sodas caused violent behaviour.

UK's Armed Teenagers Double in Number
A new survey has revealed that the number of teenagers convicted for carrying knives has doubled in a decade in England.

The new study was based on answers to questionnaires filled out by 1,878 public-school students aged 14 to 18 in the inner Boston area, where Hemenway said crime rates were much higher than in the wealthier suburbs.

The overwhelming majority of respondents were Hispanic, African-American or mixed; few were Asian or white.

Diverse Ways Adopted by Youth to Deal With Violent Neighborhood
A new University of Chicago study has shown that violent experiences cause teens growing up in dangerous neighbourhoods to adopt a range of coping strategies to avoid violence, with

Among the questions were how much carbonated non-diet soft drink, measured in 12-ounce (355-millilitre) cans, the teens had drunk in the previous seven days.

They were also asked whether they drank alcohol or smoked, carried a weapon or showed violence towards peers, family members and partner.

23pc of Spanish Youngsters Getting into Drunken Fights Regularly
A research carried out by the European Institute of Studies on Prevention has revealed that night-time violence among young Spaniards is becoming more common.

What emerged, said Hemenway, was evidence of "dose response," in other words, the more soda was consumed, the likelier the tendency towards violence.

Among those who drank one or no cans of soft drink a week, 23 percent carried a gun or a knife; 15 percent perpetrated violence towards a partner; and 35 percent had been violent towards peers.

At the other end of the scale, among those who drank 14 cans a week, 43 percent carried a gun or a knife; 27 percent had been violent towards a partner; and more than 58 percent had been violent towards peers.

Overall, teens who were heavy consumers of sugary fizz were between nine and 15 percentage points likelier to show aggressive behaviour compared with low consumers, even when ethnicity and other confounding factors were taken into account.

This is a magnitude similar to the link found, in previously researched, with alcohol or tobacco.

Hemenway said the study had included a couple of questions aimed at taking a children's home background into account, including whether the teen had taken a meal with his family in the previous days.

As it was only intended as a preliminary investigation, the questionnaire did not ask what kind of sodas the teens drank, he said.

"This is one of the very first studies to examine" the question, said Hemenway.

"We don't know why (there is this strong association). There may be some causal effect but it's also certainly plausible that this is just a marker for other problems -- that kids who are violent for whatever reason, they tend to smoke more, they tend to drink more alcohol and they tend to maybe drink more soft drinks. We just don't know.

"We want to look at it more carefully in following studies."

The study, published in a British journal, Injury Prevention, will revive memories of the "Twinkie Defence," a US legal landmark in which a killer successfully argued that his behaviour had been swayed by eating junk food.

The defendant in this case, Dan White, had been charged with homicide. His lawyer's successful pleading led to conviction of a lesser charge, of voluntary manslaughter.

Several studies elsewhere have established a link between very high sugar consumption and lack of social bonding or irritable and anti-social behaviour.

Some diet research has also pointed the finger at the lack of micro-nutrients as a source of aggression, but this work is still in its early stages.
