Analysing the factors associated with inconsistent condom use amongst men having sex with other men (MSM) in Ciudad Juárez, Chihuahua.
This was an observational, cross-sectional analytic study using a convenience sample (n=186) of MSM from Ciudad Juarez. Socioeconomic status, attitudes toward condom use, drug use, alcohol consumption, sexual orientation were considered as independent variables. Dependent variables were sexual behaviour related to HIV infection (inconsistent condom use in anal penetration and receiving semen in the mouth or anus).
Whereas 30 % of the MSM interviewed infrequently used a condom when they practiced receptive anal sex, when they had insertive anal sex, 39.1 % reported receiving semen in the mouth and 35.5 % in the anus. Multivariate logistic regression models were used, observing that the groups of men having the highest probability of risky sexual behavior (compared to their counterparts) were younger men (<20 years), those earning medium income, those having a negative attitude towards condom use, men using drugs or alcohol and those who reported homosexual identity.
An important percentage of MSM infrequently used a condom. The implications of our findings should be used when designing programmes for promoting condom use amongst MSM.
分析墨西哥奇瓦瓦州华雷斯市男男性行为者（MSM）中与不坚持使用避孕套相关的因素。
这是一项观察性横断面分析研究，采用来自华雷斯市的MSM便利样本（n = 186）。社会经济地位、对使用避孕套的态度、吸毒、饮酒、性取向被视为自变量。因变量是与艾滋病毒感染相关的性行为（肛交时不坚持使用避孕套以及口交或肛交时接受精液）。
在接受访谈的MSM中，30%的人在进行被动肛交时很少使用避孕套，在进行主动肛交时，39.1%的人报告口交时接受精液，35.5%的人报告肛交时接受精液。使用多变量逻辑回归模型，观察到具有最高危险性行为概率的男性群体（与其他男性相比）是年龄较小的男性（<20岁）、中等收入者、对使用避孕套持消极态度的男性、吸毒或饮酒的男性以及报告为同性恋身份的男性。
很大一部分MSM很少使用避孕套。在设计促进MSM使用避孕套的项目时，应考虑我们研究结果的影响。
