There was an increase in the number of men with diagnosed HIV reporting unprotected sex, but numerous other indicators showed no increase in risk taking. The поведение is reported in the March issue of Sexuality Research and Social Policy full text freely available.

The results contrast with those of a mathematical modelling studywidely reported by the media in February, which suggested that new HIV infections have increased in gay men since the mids, секс the greater use секс HIV секс — because of a modest rise in the мужчины of men having unprotected sex. However, it is important to note that this rise in UAI was an estimation derived from the modelling, rather than empirical data.

In relation to sex, a term previously секс to describe sex without condoms. However, we now know that protection from HIV can be achieved by taking PrEP or the HIV-positive partner having мужчины undetectable viral load, without condoms being required. The term has fallen out of favour секс to its ambiguity. A range of complex mathematical techniques which aim to simulate a sequence of likely future events, in order to estimate the impact of a health intervention or the spread of an infection.

Comparing one group with another, expresses differences in the odds of something happening. An odds мужчины above 1 мужчины something is more likely to happen in the group of interest; an odds ratio below 1 means it is less likely to happen.

Studies aim to give information that will be applicable to a large group of people e. Because it is impractical to conduct a study with such a large group, only a sub-group a sample takes part in a study. Statistical tests are used to judge whether the results of a study could be due to chance and would not be confirmed if the study was repeated. Their new analysis compares responses from andtwo years in which поведение same set of detailed questions about sexual behaviour were asked. Most questions were about whether an individual had engaged in a sexual practice at least once during мужчины previous year — the data cannot, поведение, give an insight into the frequency of risk taking.

Moreover, as the same men did not complete the survey in each year, changes over time must be interpreted with some caution. To minimise bias, only those men recruited online were included in this analysis face-to-face recruitment methods differed from year to year.

Nonetheless, there were some differences between the samples of and men recruited in andrespectively. Inthe sample was considerably older and better educated, somewhat more ethnically diverse, and had a slightly different geographical spread from мужчины first survey. While the researchers did adjust for these factors in their statistical analyses, мужчины is possible that there were other confounding factors that they did not identify.

As has been previously reported from this surveythe number of men taking HIV tests has increased over time. The number who had ever taken a test went up from As a consequence, the number of men with diagnosed HIV went up from 3. After statistical adjustment, men in were around half as likely to report that they had never tested for HIV odds ratio 0. Looking at the whole samples, there were no statistically significant changes in the number of sexual partners reported by participants. However, among men who had either tested negative or never tested, there were statistically significant falls in the number of men who had had five or more sexual partners in the past year.

The one exception was for men with diagnosed HIV. In мужчины, After statistical adjustment, in the later survey men were twice as likely секс report unprotected sex odds ratio секс. For all of these, there were no statistically significant changes from to The only exception was a small increase поведение the number of men reporting any anal intercourse. However there was no evidence for either phenomenon in the data. They мужчины note the possibility that uptake of HIV testing has increased disproportionately in men at greatest risk of HIV поведение men most likely to report unprotected sex.

In поведение words, with such substantial changes in HIV-testing behaviours in recent years, the nature and characteristics of the population of gay men with HIV may have also changed. Surveys of gay men recruited in Glasgow and Edinburgh bars observed an increase towards the end of the s in the number of men with multiple unprotected anal intercourse partners, but found no evidence for further increases between and Surveys of men секс in London gyms similarly reported an increase in the number of men reporting Секс with men of an unknown or different HIV status between and поведение, followed by a decrease and a levelling off поведение and In terms of men reporting any unprotected anal intercourse in the previous year, the data did suggest an increase between andbut this did not quite reach statistical significance.

Finally, it is worth noting the recent mathematical modelling study. This suggested that, although поведение therapy has significantly reduced HIV transmission, the annual number of new HIV infections has nonetheless risen since the late s.

The modelling suggested that this could most logically be explained by a modest rise in unprotected sex between and But the latter figure is an output of the model, rather than мужчины data that was поведение into it. When its results are published — probably in the next секс or two — they are likely to be of considerable interest, due to NATSAL recruiting a large, representative sample of the adult UK population.

Hickson F et al. Sexuality Research and Social Policy Full text available here. Numbers of sexual partners fell, as did the proportion of men reporting unprotected anal sex. It involves HIV-negative individuals taking daily antiretroviral therapy to reduce their risk of infection with the virus. Amyl, butyl or isobutyl nitrite, are recreational drugs sniffed during sex to both intensify the experience and relax anal sphincter muscles.

Regulatory agency that evaluates and approves medicines and medical devices for safety and efficacy in the United States. The FDA regulates over-the-counter and prescription drugs, including generic drugs. However, there is concern in some quarters that use of PrEP may lead to increases in sexual risk behaviour.

Mathematical models suggest that even modest increases in the proportion of gay men reporting unprotected sex could wipe out the beneficial effect of PrEP at a community level. However, the precise impact of PrEP on sexual risk taking is highly controversial.

A total of men were recruited to the study between and All reported anal sex with another man in the preceding twelve months.

The study was double blind and placebo controlled. Participants were randomised either to start treatment immediately or to wait for nine months. The men were interviewed at baseline and then every three months about their sexual risk behaviour and use of recreational and erectile dysfunction drugs. The study lasted 24 months. At baseline, the men reported a mean of 7. This fell significantly during follow-up to a mean of 6 partners between months 3 and 9 and a mean of 5.

These declines were similar in the immediate- and delayed-treatment arms. The mean number of reported HIV-positive partners or partners of an unknown status fell from 4.
