HIV rates are escalating in Indonesia. At Timika in Papua, the world's largest gold mine employs many single and migrant men, who frequently have sex with female sex workers (FSWs). We investigated trends of sexually transmissible infections (STIs) in FSWs in Timika.
From 1997 to 2002, FSWs at clinics were recruited for their first STI screening. Sociodemographic and sexual behaviour data were obtained and laboratory tests were performed to diagnose STIs.
From 1997 to 2002, 3086 FSWs were recruited. Prevalence of gonorrhoea varied from 11% to 19% (P = 0.71). Positive treponemal serology varied from 1.4% to 5.1% (P = 0.50). Trichomoniasis declined from 16% to 11% (P = 0.03). HIV infection increased significantly from 0.0% to 1.4% (P = 0.002). Chlamydia prevalence did not significantly change from 33% in 1997 compared with 41% in 1998 (P = 0.10). Consistent condom use was low, but increased from 8% to 16% (P = 0.001). Any STI was independently associated with younger age, high frequency of sexual activity, and not using contraceptives.
The high rates of STIs, low condom use and increasing prevalence of HIV among these FSWs require enhanced interventions, and consideration of periodic presumptive treatment. A partnership with industry can aid and sustain an intervention program.
印度尼西亚的艾滋病毒感染率正在上升。在巴布亚省的蒂米卡，世界上最大的金矿雇佣了许多单身和流动男性，他们经常与女性性工作者（FSW）发生性行为。我们调查了蒂米卡女性性工作者中性传播感染（STI）的趋势。
1997年至2002年，诊所中的女性性工作者被招募进行首次性传播感染筛查。获取了社会人口统计学和性行为数据，并进行了实验室检测以诊断性传播感染。
1997年至2002年，共招募了3086名女性性工作者。淋病患病率从11%至19%不等（P = 0.71）。梅毒血清学阳性率从1.4%至5.1%不等（P = 0.50）。滴虫病从16%降至11%（P = 0.03）。艾滋病毒感染率从0.0%显著上升至1.4%（P = 0.002）。衣原体患病率与1997年的33%相比，1998年为41%，无显著变化（P = 0.10）。持续使用避孕套的比例较低，但从8%增至16%（P = 0.001）。任何性传播感染均与年龄较小、性活动频率高以及未使用避孕药具独立相关。
这些女性性工作者中性传播感染率高、避孕套使用率低且艾滋病毒感染率不断上升，需要加强干预措施，并考虑定期进行推定治疗。与企业建立伙伴关系有助于开展并维持干预项目。
