(Seoul = Yonhap News) Reporter Jandi Kim = A study found that men have a vitamin D deficiency in their body, and women’s immunity decreases when they lack exercise.

On the 27th, a research team led by Professor Oh Su-yeon of the Chaum Immune Enhancement Clinic and Professor Choi Sang-woon of the Clinical Genomics Center obtained these results by using and analyzing ‘NK cell activity’ as an immunity index for 2,95 people who received health checkups in Chaum from 2016 to 2018 said.

NK cells are immune cells called natural killer cells that play an important role in fighting viral infections or preventing cancer. As previous studies revealed that decreased NK cell function increases the risk of cancer and infectious diseases, the NK cell activity test is being used to determine the functional status of immunity.

According to the results of the study, NK cell activity decreased with age in men. This phenomenon was observed only in men, and the NK cell activity decreased sharply with age in those aged 50 or older than in men aged 18 to 40.

It was confirmed that NK cell activity was low even when vitamin D was deficient or exercise was insufficient.

Vitamin D deficiency had a greater effect on men, and lack of exercise had a greater effect on women and the elderly.

In men, the risk of low NK cell activity increased by 2.8 times when vitamin D deficiency occurred, and by 1.9 times in women when not exercising.

In both men and women over the age of 60, lack of exercise was found to have a significant impact on the weakening of immunity. In this age group, the risk of low NK cell activity when exercise was insufficient reached 5.6 times.

The research team said that it is meaningful in that it revealed the difference in NK cell activity according to age and sex, and the effect of vitamin D and exercise on NK cell activity that affects immunity.

Professor Oh said, “As a lack of vitamin D leads to a decrease in NK cells, men must maintain a good nutritional status to improve immunity.” “For women and the elderly, exercise is an important factor for immunity, so exercise 2 to 4 times a week.” It’s good to exercise for 1 to 2 hours.”

The research results were published in the latest issue of Frontiers in Immunology.
