According to the National Health Statistics of the Korea Centers for Disease Control and Prevention in 2021, the younger the age, the longer the average daily sitting time, except for those over 70 years old. 9.7 hours for 19-29 years old, 9.0 hours for 30-39 years old, 8.6 hours for 40-49 years old, and 8.4 hours for 50-59 years old. Although not included in the analysis, it is predicted that this age group will spend the longest time sitting, given that the age group of 18 and under is mainly students and they often sit at school for study.
On the 16th of last month, British and Finnish scientists published an analysis in the international journal ‘Journal of Clinical Endocrinology and Metabolism’ that if the time spent sitting in childhood and adolescence increases, the frequency of inflammation in adults increases and the condition worsens. The longer you spend sitting down as a child, the worse your health becomes when you get older.
According to the World Health Organization (WHO), more than 80% of adolescents worldwide do not meet the recommended daily amount of physical activity. Lack of physical activity is estimated to cause about 500 million cases of heart disease, obesity, diabetes and other non-communicable diseases by 2030. It is analyzed that the resulting economic loss will reach 27 billion dollars (approximately 35 trillion won).
In particular, lack of physical activity has been shown to induce chronic low-grade inflammation. Chronic low-grade inflammation means that a low-level inflammatory response continuously occurs in the body, causing pain hypersensitivity and reducing the function of muscle cells and the activity of immune cells.
It is analyzed that it is related to various diseases such as cardiovascular, neurological and musculoskeletal diseases, and cancer. It has also been shown to affect vascular damage in adolescents and young adults.
A research team from the University of Bristol, the University of Exeter in the UK, and the University of East Finland in Finland confirmed these problems through a 13-year follow-up study. The research team followed 792 children aged 11 to 24 years of age. We analyzed the relationship between sitting time and chronic low-grade inflammation in the body at the ages of 11, 15, and 24, respectively.
As a result, it was found that the degree of chronic low-grade inflammation worsened as the time of sitting increased. The research team explained, “It is analyzed that as the time of sitting increases, blood pressure rises, resulting in these results.”
However, the way to reduce the occurrence of chronic low-grade inflammation was simple. It was found that the frequency and severity of inflammation decreased as light physical activity, such as walking or standing, increased. Rather, it was more effective than doing active physical activities such as running fast. The research team said, “Light physical activity was about three times more effective than vigorous physical activity in reducing the frequency or severity of inflammation.” first,” he said.
The research team also advised that body fat mass should be reduced to increase the effect of light physical activity. It was found that the inflammation reduction effect through light physical activity was reduced by about 30% when body fat mass increased. The research team analyzed, “The effect of body fat mass on the occurrence of inflammation is also great.”
Andrew Agvaye, a professor at the University of Eastern Finland’s School of Medicine who led the study, said: “This study confirms that low-level inflammation is exacerbated by increased sitting time from childhood to adolescence. It can become a hidden hero who can prevent the side effects of time and prevent diseases.”
