概括
在2015年,从未母乳养对日本妇女的癌症发病率 (0.3%) 和死亡率 (0.1%) 贡献最小. 日本的高母乳养率可能解释了这些低的人口可归因部分 (PAF) 的癌症.
科学领域:
- 在瘤学瘤学.
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- 哺乳被认为是预防各种癌症的保护因素.
- 了解由于缺乏母乳养而导致的癌症的人口归因分数 (PAF) 对公共卫生干预至关重要.
- 之前的研究表明,在其他全球人口中,从未母乳养与癌症相关的重大癌症负担.
研究的目的:
- 估计2015年日本妇女从未母乳养的癌症发病率和死亡率的人口归因分数 (PAF).
- 将这些估计与其他国际研究的结果进行比较.
主要方法:
- 利用21世纪婴儿长度调查 (LSB21) 对40岁以下妇女的数据,以及针对40-69岁妇女的日本公共卫生中心下一代前性研究 (JPHC-NEXT) 的数据.
- 定义"永远母乳养"为研究的最佳频率.
- 用不同年龄组的标准公式计算癌症发病率和死亡率的PAF.
主要成果:
- 从未母乳养与2015年日本女性总癌症发病率的0.3%有关.
- 从来没有母乳养占2015年日本女性癌症总死亡率的0.1%.
- 这些分数明显低于其他国家的研究报告的分数.
结论:
- 由于从未母乳养而导致的癌症的可归因比例在日本妇女中很低.
- 在日本,高患母乳养率是导致这些较低的癌症PAFs的一个可能因素.
- 研究结果表明,日本广泛的母乳养实践显著减轻了与哺乳相关的癌症负担.

02:59Cancer Prevention
6.0K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

02:12What is Cancer?
10.4K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.

01:07Teratogenicity
2.3K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

01:22Healthcare Associated Infections II: Preventive Measures
2.3K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

02:59Biological Effects of Radiation
15.1K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
