Stress-free measures against STDs (chlamydia information)

Sexually transmitted infections are on the rise.It's not just the "young woman's syphilis" that's been in the media lately.According to the number of reports of sexually transmitted diseases published by the Ministry of Health, Labor and Welfare's Health Service Bureau, genital chlamydia among men aged 40 and over is on the rise.This column deals with the management of sexually transmitted diseases, which is necessary to enjoy daddy activities with peace of mind. Consider measures against sexually transmitted infections.

《Chlamydia increased only in middle-aged and older men》

Among the many sexually transmitted diseases, syphilis and HIV have been reported in all cases, while gonorrhea, genital chlamydia, genital herpes, and condyloma acuminata have been reported at fixed points, and are published on the website of the Ministry of Health, Labor and Welfare.The National Institute of Infectious Diseases, which is very active in the fight against the new coronavirus, is responsible for data collection at the field level.

The Central Conference of Public Health Nurses (one of the conferences run by the Health Bureau) will focus on infectious diseases that have seen major changes in the total population of the population as a whole.For example, the number of syphilis cases reported in 1987 (2928) was comparable to that of the 2015 epidemic (2697). .

On the other hand, infectious diseases that do not pose a threat to the nation as a whole are not analyzed in detail.Since it is a tax-funded conference body, work can be divided according to the threshold of "threat to the people."

However, it is important to note that "not parsed" does not equal "no problem at all".Heinrich's law, which is used in occupational accidents, is also applied to infectious diseases, and behind the serious matter of "syphilis" lies several causes for concern, one of which is genital chlamydia infection in middle-aged and older men.Despite the marked decline in females in all age groups and in males under the age of 30, there is an increasing trend only in middle-aged and older males.

《Genital chlamydia infection in numbers》

Take a look at the table below.This is a summary of the "Annual change in the number of sexually transmitted diseases (STDs) reported by age (1999-year age group)" on the Ministry of Health, Labor and Welfare website.To make it easier to understand the changes, we compared the oldest figures (2020) and the latest figures (5) on the current website.Since the variation is large in a single year, we have compared the data for XNUMX years together.

Sex	period	Number of reports and increase/decrease by age
		24 and under	25 ~ 39 old	Over 40 years old
Male	1999-2003 year	2,7494	39,417	13,458
	2016-2020 year	16,930	32,177	15,694
	Increase/decrease in the above period	0.62	0.82	1.17
Female	1999-2003 year	49,286	41,986	7,459
	2016-2020 year	31,762	23,174	4,968
	Increase/decrease in the above period	0.64	0.55	0.67

This table clearly shows that when viewed on a timescale of 20 years, only middle-aged and elderly men have a rate of change of "1.17", exceeding 1, and that genital chlamydia infections are exceptionally increasing.

You may have seen an article on the website of a clinic that said, "Chlamydia infections are increasing among young people."In fact, in 2020, the number of reported infections among women in their 20s was the highest in the last 10 years.However, the "increasing trend" for chlamydia is a relatively short timescale of 10 years, and a different interpretation is required than for syphilis, which is compared to the epidemic season half a century ago.When it comes to chlamydia infections, the 2015 trough was the lowest level of decline on record, and this is the comparison, so the recent numbers inevitably appear to be on the rise.

《Middle-aged men are not good at dating? 》

Chlamydia is the most prevalent sexually transmitted disease among Japanese.For that reason, it is also a sexually transmitted disease that can be dealt with, as it is enlightened, and the examination system and treatment methods are in place.From another point of view, it can be seen that the attitude to deal with chlamydia can be read as awareness of prevention of sexually transmitted infections.

Now, when measured over a 20-year timescale, the rate of decrease in genital chlamydia infections among the younger generation was large for both men and women.The activities of everyone involved in public health, such as schools and venereal disease clinics, must have appeared in a visible way.It's kind of a silly thing to say, but there are people who say, "I can't help myself because writing about 'STIs among young people is declining' makes me feel better!"But it is true that the number is decreasing, and I feel that people in their 20s now have a wider knowledge of sexually transmitted diseases than they did 20 years ago, and I feel that they are getting along well.

It is men in their 40s and older who are not good at dealing with sexually transmitted diseases. Some people may think that they don't care about diseases that can be cured with medicine even if they get infected, but genital chlamydia is a "coal mine canary", a sensor to prevent infectious diseases.It's the same as the broken windows theory.

《Sexually Transmitted Diseases and Normalcy Bias》

The increase in chlamydia among middle-aged and older men is probably the result of many people letting their guard down, saying, "I'm the only one who's okay."

Papa-katsu believes that a “healthy” relationship between young women and middle-aged and elderly men that respects each other is established.Young women are reducing genital chlamydia infections compared to 20 years ago, so middle-aged and older men are also making efforts.In the next installment, I will introduce that middle-aged and older men are more likely to be infected with syphilis than young women.
