The researchers found that women who have completed at least three years of college courses are 23% more likely to develop glioma than women who have only completed nine years of basic education and never attended college. For men, the probability of similar tumors in men who have completed college education is higher than that in men who have never attended college 19%.
Although we don't know the reason behind it, amal, a research assistant and one of the study authors at the Children's Health Research Center of University College London? Kanunka said: "The reason for this phenomenon is that people with higher education are more likely to find the initial symptoms and receive early treatment than those without higher education. Therefore, people with higher education are more likely to be diagnosed. "
In the study, in order to determine whether Swedes became cancer patients in a certain period of time, the researchers looked up the data of 4.3 million Swedes in the Swedish general population register and tracked their data from 1993 to 17. At the same time, they also collected information about the education level, income, marital status and professional status of these subjects.
According to the data published in the Journal of Epidemiology and Community Health on June 20th this year, in the study of 17 years, * * * 5735 men and 710/women suffered from brain tumors.
In addition, the study found that the occurrence of brain tumors is not only related to the level of education, but also related to personal income. The data show that during the study period, the probability of glioma in men with higher income is higher than that in men with lower income 14%. However, among women, we have not found a positive correlation between cancer risk and income level.
In addition, the study also found that men who are engaged in management work and have made achievements in professional fields are 20% more likely to develop glioma than men who are engaged in manual work. At the same time, the probability of acoustic neuroma in men engaged in management work is 50% higher than that in men engaged in manual labor. Acoustic neuroma is a tumor that grows on the auditory nerve of the brain and affects people's hearing and balance.
Moreover, the researchers also found that the probability of meningioma (a benign tumor) in women who have completed three years of college education is higher than that in women who have not received higher education 16%.
These new findings are consistent with previous studies. The researchers said that in previous studies, they found that the risk of brain tumors was related to higher socioeconomic status.
However, the researchers said: "The new study only shows the relationship between specific brain tumors and certain factors. Studies have not shown that these factors directly lead to brain tumors. At the same time, lifestyle also plays an important role. But we still can't study the relationship between lifestyle and brain tumors. "
The relationship between education level and brain tumor is not a brand-new topic.
Dr Raj K. Narayan, director of neurosurgery at the North Shore University Hospital in Manhasset, new york, said: "There has always been a rumor among neurosurgeons that smart people are more prone to brain tumors." However, he did not participate in this research.
Dr narayanan said in an interview with us: "I was a little surprised when I saw the results of this study. I didn't expect that the rumors that have been circulating might be true. Perhaps, we still don't know the mechanism behind this connection. There may be more brain cells, and people with more active brains are at greater risk of brain tumors. "
