HIV prevalence estimates for pregnant women from unlinked anonymous surveys are becoming increasingly available and can be used to determine the prevalence of HIV in women in the same population. The ratio of prevalence in pregnant women to that in all women is influenced by HIV-related risk behaviours that are different for pregnant and nonpregnant women and also by differences in fertility level among infected and uninfected women. This ratio is affected by biases that are likely to be culturally and socially specific. A model is proposed for the qualification and quantification of these biases and hence the estimation of general female population prevalence from serosurveillance data on pregnant women.
来自非关联匿名调查的孕妇艾滋病毒流行率估计数据越来越多，可用于确定同一人群中女性的艾滋病毒流行率。孕妇与所有女性的流行率之比受孕妇和非孕妇不同的艾滋病毒相关风险行为以及感染和未感染女性生育水平差异的影响。这一比例受可能因文化和社会而异的偏差影响。本文提出了一个模型，用于对这些偏差进行定性和定量分析，从而根据孕妇血清监测数据估算一般女性人群的流行率。
