Due to the high prevalence and morbidity sexually transmitted diseases are highly relevant to public health, especially for women.
To determine and compare the behavioral and biological risks associated with human immunodeficiency virus acquisition.
A group of 253 women who voluntarily sought anonymous testing were interviewed to find out their behavioral risk. Biological risk was identified by means of gynecological exam, colposcopy as well as blood and cervicovaginal sampling for serological and microbiological exams. Using known traditional risk factors, a table of scores classified the subjects into high, low and absent for behavioral and biological risks. Frequency and percentage of each risk was tabulated and the correlation between risks was obtained by calculating the Kappa statistic.
79.8% of subjects were found to have behavioral risks, and 79.1% biological risks. It was also found that 66.7% of the women (169) with high behavioral risk also had high biological vulnerability. However, 31 out of 51 women without any behavioral risk had biological vulnerability 12.2 %. The Kappa statistic demonstrated low agreement between the latter risks [K = 0.05 95% CI (-0.06 to 0.17)].
Women who seek care in centers for anonymous testing have high biological risk, which is neither proportional nor concurrent to behavioral risk. The low concordance found between these risks suggests the need for routine gynecological investigation (clinical and microbiological) for all women.
由于性传播疾病的高患病率和发病率，它们与公共卫生密切相关，尤其是对女性而言。
确定并比较与人类免疫缺陷病毒（HIV）获得相关的行为和生物学风险。
对 253 名自愿接受匿名检测的女性进行访谈，以了解她们的行为风险。通过妇科检查、阴道镜检查以及血液和宫颈阴道采样进行血清学和微生物学检查，确定生物学风险。利用已知的传统风险因素，通过评分表将研究对象分为行为风险高、低和无风险。对每种风险的频率和百分比进行制表，并通过计算 Kappa 统计量获得风险之间的相关性。
79.8%的研究对象存在行为风险，79.1%存在生物学风险。还发现，66.7%（169 名）具有高行为风险的女性也具有高生物学脆弱性。然而，51 名没有任何行为风险的女性中有 31 名（12.2%）具有生物学脆弱性。Kappa 统计量表明，后一种风险之间的一致性较低[K=0.05（95%置信区间：-0.06 至 0.17)]。
在匿名检测中心寻求护理的女性具有较高的生物学风险，该风险既不成比例，也不与行为风险同时存在。发现这些风险之间的一致性较低，表明需要对所有女性进行常规的妇科检查（临床和微生物学）。
