Soft drink consumption patterns and awareness of associated health risks among undergraduates at the University of Peradeniya, Sri Lanka: a cross-sectional study
This cross-sectional study of 480 undergraduates at the University of Peradeniya, Sri Lanka, reveals that while most students consume soft drinks less than once a week primarily for taste and thirst, male students drink more frequently and a small minority report experiencing health issues, highlighting a need for targeted health awareness interventions.

The Sugar Rush and the Silent Sip
Imagine your body is a high-performance car. For years, scientists have known that putting the wrong kind of fuel in the tank—like pouring syrup into a diesel engine—can cause the engine to sputter, rust, and eventually break down. In the world of human health, "soft drinks" are that tricky fuel. They are bubbly, sweet, and often caffeinated beverages that taste great but are packed with sugar and acids. While they might give you a quick energy boost, experts have long warned that drinking too many of them can lead to serious trouble, like making your teeth crumble, your stomach ache, or your heart work too hard.
Now, think of university students as the drivers who have just gotten their license. They are at a pivotal moment where they decide how to run their own engines. They are free to choose what to drink, often without parents watching over their shoulders. But here is the big question: Do these young drivers actually know that the sugary soda in their hand is the same stuff that might rust their engine later? This is the mystery researchers wanted to solve. They wanted to see if knowing the dangers of the "bad fuel" actually stops people from drinking it, or if the taste is just too strong to resist.
The Study: A Sip of Truth from Peradeniya
A team of researchers from the University of Peradeniya in Sri Lanka decided to investigate this very question. They looked at 480 undergraduate students, a group representing nine different faculties, from agriculture to veterinary medicine. Think of them as a giant, diverse pool of young drivers, all in the same university "garage." The researchers asked them simple questions: How often do you drink these fizzy, sugary drinks? Do you know what they do to your body? And does knowing the truth change what you buy?
The Drinking Habits: A Slow Fade
The study found that while soft drinks are popular, the students aren't guzzling them every single day. In fact, more than half of the students (51.25%) said they drink them less than once a week. It's like a party that starts loud but quiets down as the night goes on. The researchers noticed a clear pattern: first-year students were the biggest fans, drinking the most. But as students moved into their second and third years, their drinking habits slowed down. It seems that as students get older and more mature in university, they naturally start to sip less.
However, there was a twist. The students who drank the most weren't necessarily the ones who knew the least. In fact, the students in the Faculties of Medicine, Engineering, and Dental Sciences—those who study the human body and teeth the most—reported the highest frequency of consumption compared to students in other faculties. It's a bit like a mechanic who knows exactly how a car engine works but still drives with the handbrake on. The researchers suggest this might be because these students are under huge stress and have long study hours, so they reach for the quick energy boost of a soft drink despite knowing it's not the best choice.
The "Fuel" Choices: Thirst and Taste
When asked why they drank these beverages, the answers were straightforward. The top reasons were simply to quench thirst (47.3%) and because they tasted good (38.1%). It wasn't about brand names or fancy packaging; it was about immediate satisfaction. Most students bought their drinks from hostel canteens or shops near their homes. Interestingly, many students admitted to using straws, but not always. Only about 18.5% used a straw "always," while 72% used one "sometimes." This inconsistency is like wearing a helmet only when you feel like it; it doesn't offer full protection against the acid in the drinks that can wear down teeth.
The Awareness Gap: Knowing vs. Doing
The researchers also tested how much the students knew about the health risks. The results were a mix of good news and bad news.
- The Good News: Most students (84.7%) knew that soft drinks are linked to diabetes. They also knew about sugar-free options and the "traffic light" system used to label food.
- The Bad News: There were big holes in their knowledge. Only 29.2% of students realized that soft drinks cause "tooth erosion" (where the acid literally melts the tooth surface). Fewer than half knew about the link to heart disease (26.0%) or weight gain (35.2%).
It's as if the students knew the car might break down if they used bad fuel, but they didn't realize the fuel was also eating away the tires.
Does Knowing Help?
The big question was: Does knowing the risks make students drink less? The study found a very small, but real, connection. Students who knew more about the dangers tended to drink soft drinks slightly less often. The researchers described this as a "weak negative correlation." It's like a dimmer switch: turning up the knowledge knob doesn't shut the light off completely, but it does make it a little dimmer. However, the study also found that money played a role. Students from families with higher incomes (over 50,000 LKR) tended to drink soft drinks more frequently, likely because they had more money to spend on treats.
The Takeaway
The study concludes that while these university students have some idea that soft drinks aren't healthy, their knowledge isn't deep enough to stop them from drinking them, especially when they are stressed or in a social setting. The researchers suggest that just telling students "this is bad" isn't enough. They recommend that universities should do more than just hand out facts. They should change the environment—like regulating what drinks are sold in canteens or using clear labels to nudge students toward better choices.
In short, the young drivers at the University of Peradeniya know the road has potholes, but they are still driving fast over them because the ride feels good. The researchers hope that by understanding these habits, they can help build better roads for the future.
