The Double Burden of Adolescents in Bandung, West Java, Indonesia: Undernutrition and Emerging Metabolic Risks
A cross-sectional study of 203 adolescents in Bandung, Indonesia, reveals a double burden of malnutrition where undernutrition, normal weight, and overnutrition coexist with high rates of metabolic and lipid abnormalities, particularly dyslipidemia, indicating that metabolic risk assessment must extend beyond BMI alone.

Imagine your body as a high-performance car. For years, scientists have been worried about two very different problems that can break this car down. The first is "undernutrition," which is like trying to drive a race car with an empty gas tank and missing spark plugs; the engine sputters because it simply doesn't have the fuel or parts to run right. The second is "overnutrition," which is like stuffing the car's trunk with so much heavy junk that the engine overheats and the tires can't handle the weight.
For a long time, we thought these two problems happened in different neighborhoods: one in poor areas and one in rich ones. But recently, scientists noticed something strange happening in many cities around the world. They call this the "double burden." It's like finding a car that is both starving for fuel and weighed down by junk, all at the same time. This paper looks at teenagers in Bandung, Indonesia, to see if this weird mix is happening to them, and whether it's causing their "engines" (their hearts and blood sugar systems) to start making strange noises before they even hit adulthood.
The Double Trouble in Bandung
A team of researchers from Universitas Padjadjaran and the University of Otago decided to peek under the hood of 203 teenagers living in Bandung, West Java. These kids were between 15 and 18 years old, living in ten different urban villages. The scientists wanted to see if these teenagers were facing the "double burden" of malnutrition—where being too thin and being too heavy exist side-by-side—and if this was causing hidden metabolic risks, like high blood pressure or weird blood sugar levels.
Think of metabolic risk as the "check engine" light. Even if the car looks fine on the outside, the light might be blinking inside. The researchers checked the teenagers' weight, waist size, blood pressure, and blood chemistry to see if that light was on.
What They Found: A Surprising Mix
The results were a bit like finding a box of mismatched socks. The teenagers didn't fit neatly into just one category.
- The Weight Situation: Most of the kids, about 147 out of 203 (72.4%), were at a "normal" weight. But the rest were split down the middle. About 19 kids (9.3%) were undernourished (too thin), while 37 kids (18.3%) were at risk of being overweight or were already overweight. This confirmed the "double burden": the group had both hungry kids and heavy kids living in the same city.
- The Hidden "Check Engine" Lights: Here is where it gets interesting. You might think only the overweight kids would have "check engine" lights on. But the scientists found that metabolic risks were popping up everywhere, even in the kids who looked perfectly healthy or were too thin.
- Blood Pressure: About 18.7% of the group had high blood pressure.
- Blood Sugar: 5.4% were in the "prediabetes" zone, meaning their blood sugar was starting to get a little too high.
- The Real Trouble Maker (Cholesterol): The biggest surprise was the cholesterol. Dyslipidemia (an imbalance of fats in the blood) was the most common problem. Specifically, 67.5% of all the teenagers had low "good" cholesterol (HDL). That's like having a broken filter in your car's oil system. It didn't matter if they were undernourished, normal weight, or overweight; more than two-thirds of them had this issue.
The "Double Burden" in Action
The study looked closely at how these risks spread across the different weight groups:
- The Undernourished Group: Even among the 19 kids who were too thin, 31.6% had at least one metabolic risk factor (like high blood pressure or bad cholesterol).
- The Normal Weight Group: Among the 147 kids who looked healthy, 20.4% still had a metabolic risk, and a huge 74.8% had at least one lipid (fat) abnormality.
- The Overnutrition Group: As expected, the 37 kids who were overweight had the highest risk, with 56.9% having metabolic issues and 81.1% having lipid problems.
What This Means for the Future
The main takeaway from this paper is that you can't just look at a teenager's weight to know if they are healthy. The study suggests that relying only on Body Mass Index (BMI) is like judging a car only by how much it weighs, ignoring whether the engine is sputtering or the oil is dirty.
The researchers found that metabolic risks are "emerging" in Bandung's teenagers. This means the "check engine" lights are turning on earlier than we might have thought, affecting kids of all sizes. The paper concludes that we need to start checking more than just weight. We need to look at blood pressure, blood sugar, and cholesterol for everyone, not just the kids who are overweight.
The authors suggest that to fix this, we need early screening and better health education in schools and communities. They aren't saying this problem is solved, but they are sounding the alarm that the "double burden" is real, and the "check engine" lights are blinking for a lot of teenagers, regardless of how they look on the outside.
