Эффективность презервативов — как бывает в реальной жизни

Эффективность презервативов – как бывает в реальной жизни

Исследование выявило, что только каждый седьмой мужчина (13%) поддерживал 100% постоянство использования презервативов в течение всего трёхлетнего периода наблюдения; среди «принимающих» партнёров этот показатель составил 20%.

Американские исследователи оценили эффективность презервативов при анальном сексе

Американский Центр профилактики и контроля за заболеваемостью населения (CDC) опубликовал исследование, по результатам которого было выявлено, что постоянное использование презервативов предотвращают 7 из 10 случаев инфицирования ВИЧ при анальном сексе среди мужчин. В целом, эффективность презервативов составила 70,5%, а в условиях, когда ВИЧ-негативный партнер выполнял «принимающую» роль - 72,3%, сообщает aidsmap.com

По результатам этого эффективность презервативов устанавливается не в идеальных, а в реальных условиях. Очевидно, что 100% постоянное и правильное использование презервативов является более эффективными, чем установленный при исследовании показатель. Но цель исследования была в другом: анализ данных показал наиболее вероятный уровень эффективности презервативов в реальных (жизненных) условиях, что было достигнуто за счёт сравнения уровня заболеваемости ВИЧ-инфекцией среди мужчин-геев, заявивших о постоянном использовании презервативов в течение предыдущих месяцев, с заболеваемостью среди мужчин, которые вообще не пользовались презервативами за тот же период времени.

По результатам анализа Центра профилактики и контроля за заболеваемостью (CDC) было сделано два дополнительных вывода. Во-первых, презервативы практически не оказывали никакого сдерживающего эффекта на заболеваемость среди группы участников, заявивших о периодическом (время от времени) использовании презервативов. В этой группе максимальный защитный эффект презервативов составил всего 25% среди ВИЧ-негативных «принимающих» партнёров. Однако это не означает, что периодическое использование презервативов вообще не является эффективным. Результаты исследования доказывают одно: поскольку понятию «периодического использования презервативов» все еще не дано однозначного определения, в рамках диапазона частоты использования презервативов (варьирующего от «постоянного» до «нулевого») существует граница, при пересечении которой «периодическое» использование презервативов перестает быть эффективным.

Во-вторых, исследование выявило, что только каждый седьмой мужчина (13%) поддерживал 100% постоянство использования презервативов в течение всего трёхлетнего периода наблюдения; среди «принимающих» партнёров этот показатель составил 20%. В то же время, только 4,4% мужчин вообще никогда не пользовались презервативами в течение того же периода наблюдения. Таким образом, периодическое использование презервативов являлось наиболее типичным проявлением поведения на протяжении длительного времени.

Комментарий AIDSMAP.COM: в действительности не существует статистической разницы между 70% эффективностью презервативов, выявленной в рамках этого анализа, и 80% эффективностью, установленной при проведении мета-анализа среди гетеросексуального населения при вагинальном сексе. Важно повторно отметить, что цель этого анализа - не в определение максимально вероятной эффективности презервативов, которая очевидно выше показателя, полученного в этом исследовании, а в определении наиболее вероятной границы эффективности, которая может быть достигнута в реальных условиях, учитывая то, что население не всегда относится к презервативам, как к простым и практичным средствам профилактики.

Эффективность презервативов – как бывает в реальной жизни

Другой вероятной причиной возникновения разницы показателей возможно стало то, что некоторые участники могли выдавать желаемое за действительное, стараясь при этом избегать менее приемлемого варианта - «неиспользование презервативов». Это в свою очередь означает, что истинный уровень использования презервативов мог быть ниже заявленного участниками, что подразумевает их более высокую эффективность.

    I’m the co-founder of JustCBD Store label (justcbdstore.com) and I’m presently aiming to broaden my wholesale side of company. It would be great if someone at targetdomain can help me 🙂 I considered that the most effective way to accomplish this would be to connect to vape stores and cbd retail stores. I was hoping if someone could suggest a trustworthy web site where I can buy UK Vape Shop Database I am presently considering creativebeartech.com, theeliquidboutique.co.uk and wowitloveithaveit.com. Not sure which one would be the best solution and would appreciate any advice on this. Or would it be easier for me to scrape my own leads? Suggestions?

    The next time I read a blog, I hope that it does not fail me just as much as this one. After all, I know it was my choice to read, however I genuinely thought you would have something interesting to say. All I hear is a bunch of complaining about something you could possibly fix if you weren’t too busy looking for attention.

    I’m amazed, I have to admit. Rarely do I encounter a blog that’s equally educative and amusing, and without a doubt, you have hit the nail on the head. The problem is something which not enough people are speaking intelligently about. Now i’m very happy I came across this in my hunt for something relating to this.

I had been wondering if your web hosting is OK? Not that I am complaining, but slow loading instances times will sometimes affect your placement in google and can damage your high quality score if ads and marketing with Adwords. Anyway I am adding this RSS to my email and could look out for a lot more of your respective exciting content. Ensure that you update this again very soon.

    When I originally commented I clicked the -Inform me when brand-new comments are included- checkbox as well as now each time a comment is included I get four e-mails with the same comment. Is there any way you can remove me from that service? Thanks!

    The following time I read a blog, I wish that it doesn’t disappoint me as much as this one. I indicate, I understand it was my option to read, yet I in fact believed youd have something fascinating to state. All I listen to is a bunch of whining concerning something that you can fix if you werent too hectic trying to find interest.

    Can I simply just say what a comfort to find someone who truly understands what they’re talking about on the net. You definitely realize how to bring an issue to light and make it important. More people should check this out and understand this side of your story. I was surprised that you aren’t more popular given that you definitely have the gift.
