【摘要】 目的利用网络规模叠加法(NSUM)估计哈尔滨市居民社交网络规模、暗娼人群规模及校正参数。方法采用分层随机抽样方法,在哈尔滨市开展社区居民和暗娼人群社交网络规模问卷调查,利用网络规模叠加法原理估计哈尔滨市居民社交网络规模、暗娼人群规模及校正参数。结果哈尔滨市居民社交网络规模原始值平均规模为271人,经标化与校正后,居民社交网络平均规模为267人,该市暗娼人群社交网络平均规模为65人。估计得到该市暗娼人群的规模约为24 116人(95%可信区间:22 910~25 322),约占该市15~49岁女性人口数的0.75%,计算得到该市暗娼人群规模校正参数为4.1。结论可采用网络规模叠加法通过居民社区调查,对艾滋病高危人群开展规模估计,但需对调查中的偏倚进行评估和调整。更多还原
