A study found that middle-aged men in South Korea with a high socioeconomic status and an irregular lifestyle pattern, as well as those with poor dietary habits, face a higher risk of diabetes.

A research team from the Department of Medical Nutrition at Kyung Hee University College of East-West Medicine followed 2332 men aged 40 to 69 who did not have diabetes, using data from the Korean Genome and Epidemiology Study. The team identified lifestyle patterns using participants' sociodemographic factors, lifestyle habits and dietary data. The participants' lifestyle patterns were classified into the following four categories: ▲healthy lifestyle, regular eating habits including breakfast frequency, with low levels of stress and overeating ▲low-carbohydrate, high-protein, high protein and fat intake with low carbohydrate intake ▲high socioeconomic status and irregular lifestyle, high education and income levels, frequent late-night meals and dining out, and low metabolic equivalents of task, MET ▲poor dietary habits, high frequencies of alcohol consumption, smoking, overeating and fast eating. The team assessed the participants' diabetes risk by conducting physical measurements, body composition analyses, blood pressure measurements and blood tests.

During the follow-up period, 675 participants developed diabetes. The analysis found that the high socioeconomic status and irregular lifestyle pattern and the poor dietary habit pattern were high-risk lifestyle patterns that increased men's risk of diabetes. Those with a high socioeconomic status and an irregular lifestyle had a 25% higher risk of developing diabetes, while those with poor dietary habits had a 21% higher risk.

The research team analyzed the findings as reflecting South Korea's unique sociocultural context, including a culture centered on high work intensity and work-related social gatherings, as well as excessive social obligations. Highly educated and high-income men primarily work in sedentary office or managerial positions, and the team explained that they experience problems such as insufficient physical activity and increased frequency of dining out and late-night meals because of long working hours, heavy workloads, frequent company dinners or business meetings, overtime work and limited leisure time. The poor dietary habit pattern was associated with a high body mass index, BMI, fasting blood glucose and glycated hemoglobin, which contribute to an abnormal metabolic state.

The research team said, “Rather than promoting healthy lifestyles in a uniform manner based on the findings of this study, it is necessary to understand complex risk factors and, based on that understanding, present specific, realistic and personalized approaches.”

Meanwhile, the findings were recently published in the ‘Diabetes&Metabolism Journal.’
