- β70% of rural adults had multiple cardiometabolic risk factors, showing how widespread undetected diabetes risk is
- βHigh blood sugar and abdominal obesity were the strongest predictors of overall cardiometabolic risk
- βSimple, low-cost tests like fasting glucose, HbA1c, and waist measurements can effectively identify high-risk individuals

What Was Studied and Why It Matters
Researchers in Peru wanted to understand how common heart and metabolic health problems β including high blood sugar, obesity, and abnormal cholesterol β are in rural communities deep in the Amazon. These populations are rarely studied, yet chronic diseases like diabetes and heart disease are rising across Latin America. The findings, published in Medicina in 2025, could have important lessons for anyone living in underserved or under-screened communities worldwide.
What the Researchers Did
The study screened 205 adults in the San MartΓn region of Peru during community health visits. Researchers checked for seven warning signs: high blood pressure, high blood sugar (hyperglycemia), abnormal cholesterol (dyslipidemia), high uric acid (hyperuricemia), general obesity, belly fat (abdominal obesity), and an unhealthy waist-to-hip ratio. If a person had two or more of these at the same visit, they were considered at high cardiometabolic risk. Researchers also asked about smoking, alcohol use, and physical activity.
What They Found
The results were striking: 7 out of 10 adults (70.2%) already met the threshold for high cardiometabolic risk. The strongest predictors of risk were:
- Abdominal obesity (belly fat) β people with excess waist size were 70% more likely to be in the high-risk group
- High blood sugar β raised the risk by 65%, making it one of the most powerful warning signs
- High uric acid levels β increased risk by 38%
- Abnormal cholesterol β raised risk by 25%
- General obesity β raised risk by 21%
Interestingly, high blood pressure, smoking, alcohol use, and physical activity levels did not independently predict who was at risk once other factors were accounted for.
What This Means for Real Patients
This study sends a clear message: you don't need expensive equipment to identify people at risk for diabetes and heart disease. A tape measure around the waist, a fasting blood sugar or HbA1c test, a basic cholesterol panel, and a uric acid check can flag serious risk β even in remote settings with limited resources.
For people already managing diabetes, this reinforces why regular monitoring matters so much. Tracking blood sugar consistently β whether through fingerstick checks or continuous glucose monitors β is one of the most powerful things you can do. MDS Diabetes offers a wide range of affordable testing supplies to help patients stay on top of their numbers, no matter where they live.
If you carry extra weight around your midsection or have been told your blood sugar or cholesterol is borderline, talk to your healthcare provider about getting a full metabolic screening. These are often quick, low-cost tests that can catch problems early β before they become serious.
Bottom Line
A landmark 2025 study found that nearly three-quarters of rural Amazonian adults already had multiple cardiometabolic risk factors, with belly fat and high blood sugar as the biggest red flags. Simple, affordable tests β including blood sugar monitoring and waist measurements β can identify who needs help most, even in low-resource settings. Early detection saves lives.
