Prediabetes also increases the risk of metabolic diseases

[의학신문·일간보사=오인규 기자] Diabetes is diagnosed when the fasting blood glucose level, the concentration of glucose in the blood, exceeds 125 mg/dL.

Professor Kim Young-sik, Department of Family Medicine, Asan Medical Center, Seoul<사진>The research team led by Professor Seo-Young Kang of the International Medical Center analyzed the relationship between fasting blood sugar levels and metabolic diseases and lifestyles in 13,000 adults who were not diagnosed with diabetes. As a result, it was confirmed that the ratio of obesity, abdominal obesity, hypertension, dyslipidemia, and excessive drinking increased consistently as the fasting blood sugar was higher for both men and women.

Those who are in the pre-diabetic stage, which is the borderline of diabetes, or whose blood sugar is constantly increasing should not be relieved, and the need to manage blood sugar early through periodic blood sugar tests is raised.

While the controversy over the validity of the fasting blood glucose test in the current national health check-up continues, this study proves for the first time the association between pre-diabetes and metabolic disease based on a large domestic population, providing evidence to support the usefulness of the fasting blood glucose test. is expected to be

The research results were published in the latest online edition of the Journal of Diabetes, a renowned journal in the field of diabetes research.

The research team studied 13,625 adults over 30 years of age who participated in the 7th National Health and Nutrition Examination Survey without a diagnosis of diabetes, according to the fasting blood sugar level, △90mg/dL or less △90~99mg/dL △100~109mg/dL △ 110~124mg/dL △125mg/dL or more was classified as a group.

As a result of analyzing the ratio of obesity and abdominal obesity in five groups divided according to the level of fasting blood sugar, it was found that the ratio increased significantly in the group with high fasting blood sugar.

For men, the proportion of obese people in the group with a fasting blood sugar of less than 90 mg/dL was 27.2%. On the other hand, the 90-99 mg/dL group more than doubled to 38.3% and the 110-124 mg/dL group to 55.2%.

A similar trend was observed in women. In the group with a fasting blood glucose of less than 90 mg/dL, the proportion of obese people was 16.9%. On the other hand, 26.8% of the group with 90~99mg/dL and 51.5% of the group with 110~124mg/dL showed that the higher the fasting blood sugar, the more obese people.

It was found that blood pressure, triglyceride, and high-density lipoprotein (HDL) cholesterol index also worsened as the fasting blood sugar level increased.

Hypertension (systolic blood pressure 140mmHg, diastolic blood pressure >90mmHg), hypertriglyceridemia (triglyceride >150mg/dL), and low HDL cholesterolemia (HDL cholesterol <40mg/dL in men and >40mg/dL in females), less than 50 mg/dL) showed an increasing rate.

On the other hand, an association between an increase in fasting blood sugar and a habit of excessive drinking was also confirmed. In the group with a fasting blood sugar of less than 90 mg/dL, the proportion of heavy drinkers was 20.8% for men and 11.0% for women. has been shown to affect

Among lifestyle habits, exercise was found to be unrelated to an increase in fasting blood sugar.

Kim Young-sik, professor of family medicine at Seoul Asan Hospital, said, “If the fasting blood glucose level is 90 mg/dL or higher, cardiovascular disease risk factors such as hypertension, obesity, abdominal obesity, and dyslipidemia increase together. It is necessary, especially if you are obese, have a family history of diabetes, or have hyperlipidemia, high blood pressure, or pre-diabetes, it is good to have your blood sugar checked every year.”

Kang Seo-young, a professor at the International Medical Center at Asan Medical Center in Seoul, said, “In order to manage blood sugar, you need to pay attention to your daily habits, such as eating habits and exercise. Instead of eating fiber-rich vegetables and whole grains, it is better to avoid foods with added sugar or high fructose and alcohol. It is recommended to increase the
