Sugar-sweetened drinks dental concern for teens

New research on sugar-sweetened drinks reveals one in seven adolescents is guzzling more than two cups a day, and is two to three times more likely to have oral health problems than those who don’t consume the beverages.

The University of Sydney study, published last month in the Australian and New Zealand Journal of Public Health, reports on the daily consumption of sugar-sweetened beverages by 3,671 year 6, 8 and 10 students.

It shows energy drinks are the most popular sweetened beverage with 20 per cent of adolescents consuming at least one cup a day.

Lead author and senior research fellow Dr Louise Hardy, from the Sydney School of Public Health and Charles Perkins Centre, said the study adds weight to the sugar tax debate, highlighting the significant and often overlooked impacts sugar-sweetened beverages have on oral health.

“Consuming two cups a day is roughly equal to 11 teaspoons of sugar which is well in excess of the World Health Organizations’ guidelines for sugar intake without even looking at food consumption,” Dr Hardy said.

“We need strategies to reduce adolescents’ consumption of sugar-sweetened beverages, not only due to weight implications, but also because of oral health.

“Bad teeth can have significant and lasting social and health impacts. It can cause considerable pain and suffering, and by changing what people eat alter their speech and quality of life.”

The research is based on data from the NSW Schools Physical Activity and Nutrition survey, a cross sectional representative survey of NSW primary and high school students.

The study reports associations between different types of sugar-sweetened beverages and oral health impacts showing all beverages, with the exception of fruit juice, were associated with frequent tooth ache or food avoidance.

Interestingly, the odds of oral health problems were highest among adolescents who drank diet soft drinks. The authors suggest further research is needed to explore if this is due to associations with other eating behaviour in this group such as the consumption of sucking confectionary, or is an effect of artificial sweeteners.

The clear association between oral health problems and diet and new generation soft drinks, such as energy, sports drinks and flavoured waters is a real concern as these beverages are marketed as a beverage of choice for adolescents. Many view them as a healthy alternative.
