Rising incidence of lung cancer in Beijing: weak association with haze

Original title: increased incidence of lung cancer experts: weak association with haze

The Beijing News (reporter Dai Xuan) every haze season, there will be frequent haze frequent carcinogenic concerns. Yesterday, the 2017 Beijing health white paper released, showed that in 2007 -2016, the incidence of lung cancer from around 55/10 million to about 70/10 million. At the meeting, experts said that according to the current monitoring results, second-hand smoke and indoor decoration pollution were strongly associated with the incidence of lung cancer, and the relationship between fog and haze was weak.

Increased incidence of acute coronary heart disease and acute stroke

Yesterday, Beijing Health Planning Commission released "Beijing 2017 health and population health report", that is, a healthy white paper. According to the white paper, the main cause of death of Beijing residents in 2017 is still chronic non communicable disease. The top three causes are malignant tumor, heart disease and cerebrovascular disease, which account for 71.7% of all deaths. Compared with 2016, the mortality rate of malignant tumor increased by 3.6%, the mortality of heart disease increased by 5.2%, and the mortality of cerebrovascular disease dropped by 2.4%. In addition, the incidence of acute coronary heart disease and acute stroke also increased.

Liu Jing, a professor of cardiopulmonary and vascular disease research institute in Beijing, said that the key to reduce the incidence of acute coronary heart disease and stroke is to control hypertension, dyslipidemia and diabetes. According to the monitoring of risk factors, the incidence of acute coronary heart disease and acute stroke is rising in male, which is related to the awareness of risk factors of cardiovascular disease, low control rate, and more common factors in men, such as smoking and obesity, and the level of prevention and control of men under 45 years of age is particularly unsatisfactory.

It is understood that in 2016, the incidence of acute coronary heart disease in Beijing, 25 years old and above, was 224.45/10 million, up 4.1% than that in 2015, and the incidence of acute stroke was 367.91/10 million, up 3.4% than in 2015.

Experts predict that with the increasing aging of the population, the health hazards caused by chronic diseases will appear in the next few years, and the prevention and control of chronic diseases is still a top priority.

Secondhand smoke is the main cause of lung cancer

According to the white paper, in 2007 -2016, the incidence of malignant tumors in Beijing registered residents was on the rise. Among them, the incidence of lung cancer was the highest in 2016, followed by colorectal cancer, liver cancer, gastric cancer and prostate cancer. The incidence of breast cancer is the highest in women, followed by lung cancer, thyroid cancer, colorectal cancer and uterine body cancer. Lung cancer is among the best in both sexes.

According to reports, last year, Beijing reported 9238 new cases of lung cancer, accounting for 19.7% of the new cases of malignant tumors. In 2007 -2016, the incidence of lung cancer in the whole city increased from 55/10 million to about 70/10 million. And every autumn and winter haze season, there are many concerns about haze carcinogenesis, then haze is the main factor leading to lung cancer?

Wang Ning, deputy director of the Beijing Institute of cancer prevention and control, said that the incidence of lung cancer in Beijing was the first malignant tumor in the 70s of last century. Monitoring showed that more than 80% of the male lung cancer patients had more than twenty years of smoking history, and secondhand smoke was the main cause of lung cancer.

Specific to environmental impact on the incidence of lung cancer, the current known indoor factors include the unique cuisine of Chinese food that causes indoor PM2.5 rise, as well as indoor decoration pollution. According to the current monitoring results, there is no strong correlation between air quality changes and the incidence of lung cancer in Beijing over the past decade. In addition, the incidence of lung cancer has increased slightly, but has been relatively stable.

The prevalence of poor eyesight declined for 4 years in students

According to the white paper, the prevalence of poor eyesight among primary and secondary school students in Beijing in the 2016-2017 academic year was 58.6%, which was basically the same as that in the school year. In recent four years, the prevalence of poor eyesight in Beijing students has continued to decline, indicating that the rising trend of poor visual acuity in primary and secondary school students has been effectively curbed, and the prevention and control work has been effective.

It is understood that in recent years, Beijing aimed at the primary and middle school students with poor vision problems, such as comprehensive reform of the classroom lighting, the adjustment of desk and chair height, the poor vision of the students to focus on monitoring and so on. Under a series of efforts, the physical quality of primary and middle school students, including vision, has been significantly improved in Beijing. In 2017, the physical health test of primary and middle school students in the city reached 93%, up 0.1% from the previous year; the good rate reached 50%, up 6% compared with the previous year; the excellent rate reached 13%, which was up 6% from the previous year.

In addition, the average height of boys and girls from 6 to 17 years was 0.17 cm and 0.08 cm in height compared with 2016. The average height of boys and girls in the 17 year old age group was 175.7 cm and 163.2 cm respectively. The height gap between urban and rural students continued to shrink.

However, the problem of obesity still needs to be paid attention to. In 2016-2017, the obesity detection rate of primary and middle school students in Beijing was 16.8%, up 3% than that in 2015-2016. Song Yuzhen, deputy investigator of the body and Health Department of the Beijing Municipal Education Committee, said that, in the whole, the students in the middle and lower grades of obese students accounted for 70%, and the parents wanted to change the idea that "the children were fat when they were young", the prevention of obesity should be from Young children and junior students grabbed them.
